Gwen Harwood Essay

To what extent does your response to ‘Father and Child’ inform your judgement of this poem and Harwood’s poetry as a whole? (In your essay refer to at least one other poem) For a true appreciation of the sanctity of life and for true spiritual maturation, an individual must accept and come to terms with the frail mortality of human life. Harwood’s poetry uses truly harrowing language to convey how her own personal experiences and relationships have led her to an enlightened state of being, with continual use of religious metaphor and allusion to convey her enriched spirituality. One of her poems that shows this is, At Mornington, is a reflection of her life, from her early childhood experiences at the beach, to her present middle-aged self, by the graves of her parents. Another that examines this is Father and Child, which is in two separate sections, the first depicting her initial confrontation with death as a child and the second conveying her acceptance of mortality when she is forced to part ways with her dying father. Life is a fleeting and impermanent state that must be treated with an almost religious sanctity in preserving and protecting it. In Father and Child, Harwood uses the innocent and protected narrative voice of a child to convey the distressing emotions she experiences while watching the pain and suffering of a barn owl, and her shock when witnessing the true nature of death. This is shown in the recurring accumulation of graphic, morbid imagery of the owl as â€Å"this obscene bundle of stuff that dropped, and dribbled through loose straw, tangling in bowels†¦Ã¢â‚¬ . This confrontation leads her into a self-discovery of her own brutality (in the metaphor â€Å"eyes†¦ mirror my cruelty†) and the need to preserve life. It also develops her mental and spiritual maturation while coming to terms with the transience of life. Experiences and relationships can also shape one’s appreciation of life and understanding of the nature of death. This is shown in part two of the poem, Night Fall, when, through a mature narrative voice, Harwood explores how, through loss, we can accept the morbid nature of death and truly appreciate life, as evidenced in the last two lines of accumulation as the narrator mourns the loss of her father, â€Å"grown to learn what sorrows, in the end, no ords, no tears can mend†. This ultimately furthers her ability to realise the value in appreciating the sanctity of life and accepting the inevitability of death. An acceptance of the transient nature of life is an essential part in achieving an enriched state of being and acknowledging the limits of human existence. The second poem, At Mornington, juxtaposes the innocence of youth in her first stanza with the mature an d understanding of her present self, throughout the rest of the poem, to signify the changing perspectives induced by experience and age. The recurring water motif in â€Å"caught by a wave†¦ among rattling shells†¦ on what flood are they borne†¦ fugitive as light in a sea-wet shell†¦Ã¢â‚¬  is symbolic of the various stages of her life and the conflicting nature of emotion, conveying the impermanent and fragile nature of life as she comes to an understanding of its sanctity. Upon reflection, an individual may also find an acceptance of death in an understanding of the transient nature of life, through reminiscing old memories and appreciating the varied yet cyclical nature of life. This is shown through the consideration of past sentiments in the last stanza, using symbolism, metaphor and an accepting tone in â€Å"the peace of this day will shine like light on the face of the waters that bear me away for ever†. Harwood is able to convey this meaning through her poetry so that a responder may be able to reflect upon their own experiences and come to a better understanding and acceptance of life, giving one the opportunity to further their own experiences and enrich their own lives with these wisdoms. It also leads an individual into a self-discovery of their own personal truths in terms of an appreciation of the life they live. For it is only through an acceptance of the frailty of human life and the inevitability of death that an individual can reach true spiritual maturation and fully appreciate life.

Theoretical Considerations Regarding Hazards And Risks Environmental Sciences Essay

The cognition of natural and technological hazards is of the extreme importance for carry oning hazard and impact appraisal surveies, every bit good as land usage planning and exigency response planning. This whole mechanism significantly contributes to the society ‘s sustainable development. For the overall comprehension of this issue, it is extremely relevant to specify the repeating constructs of this work, viz. jeopardy and hazard.The jeopardy constructTo get down with, a short ethimological analysis of the word â€Å" jeopardy † is necessary. This term has been taken by the Gallic from Arabic, where it means dice game ( Mac and Petrea, 2002 ) . Harmonizing to the Longman Dictionary of Contemporary English, 2010, † jeopardy † means â€Å" something that may be unsafe, or cause accidents or jobs † . In 1992, the United Nations International Decade for Natural Disaster Reduction secretariat published a multilingual lexicon so as to clear up and unite the significances of such footings. In this dictionary, jeopardy is defined as â€Å" a baleful event or the possibility for a phenomenon with destructive potency to look in a individual part and in a given period of clip † . Another definition is offered by the Grand Larousse Dictionary, volume V, cited by ZA?voianu and Dragomirescu in 1994: â€Å" accidental and, by and large, unforeseeable interface between two or more causal series, whose common dealingss are purely defined in every minute and whose comparative independency can merely be attributed to our ignorance and impotence † . Scheidegger, 1994, cited by ArmaAY , 2003 defined jeopardy as â€Å" the chance of rapid alteration of a system ‘s province or stable conditions † . In 1997 Grecu defined this construct as â€Å" the possibility that a potentially annihilating phenomenon appears in a certain period of clip and in a certain part. † In 1999 Octavia Bogdan and Elena Niculescu specify jeopardy as â€Å" a random phenomenon on a big graduated table, unpredictable, a deficiency of finding between clip and infinite, a qualitative lap, a threshold in the system ‘s development, downloading immense energy and doing upset, instability on the natural environmental development ‘s graduated table, in its manner towards a new province of equilibrium † . In 2000 Ozunu defines the construct under treatment as aˆza state of affairs with the potency of an accident † ; in 2001, BA?lteanu states that jeopardy is aˆza endangering event, stand foring the possibility for a potentially detrimental phenomenon to go on. † Harmonizing to him, harm to people, goods and the environment occur. Alexander, 2000, cited by Thywissen, 2006, defines hazard as aˆzan utmost geophysical event that can do a catastrophe. aˆsExtreme ‘ refers to an either positive or negative characteristic, harmonizing to the tendency it is related to. The jeopardy ‘s cardinal properties are: location, clip, magnitude and frequence. Many utmost phenomena are perennial in clip and predictable in footings of location. We define hazard as an utmost event arising from the biosphere, lithosphere, hydrosphere or atmosphere. † Mac, 2003, considers hazard as aˆzthe beginning of an utmost event with energy discharge in a certain minute and with a instead unforeseeable magnitude. In fact, jeopardy can be referred to as aˆza phenomenological class that refers to objects and phenomena ( air multitudes, H2O, lithomass, biomass, people, twisters, epidemics, temblors, avalanches etc. ) , to their actions ( inundations, clay flows, landslides, illness etc. ) every bit good as to their characteristics † ( Mac, 2003 ) . In 2003, Cardona, cited by Thywissen, 2006, offers another definition of the term: aˆzthe possibility for a natural and unsafe event to go on in a certain clip and infinite † . Generally, the construct of jeopardy is used to mention to a latent danger or to an external hazard factor of a system or exposed capable. A jeopardy is composed of three basic elements ( C. A. Ericson, 2005 ) : 1. Dangerous belongings – the basic beginning of the danger that creates the jeopardy, i.e. a unsafe energy beginning etc. 2. Initiation mechanism – the event that triggers or initiates the happening of the jeopardy, transforming the jeopardy from a inactive province to an active 1. 3. Target and menace – the individual, object, state of affairs vulnerable to damage caused by the materialisation of the jeopardy. These three elements compose the jeopardy trigon shown in figure 2.1: Figure 2.1 – The jeopardy trigon ( C. A. Ericson, 2005 ) The jeopardy trigon illustrates that all three above mentioned are interlinked. All three constituents are necessary in order to organize a jeopardy. The remotion of one portion of the trigon consequences in the riddance of the jeopardy, because it can non take to an incident. By extenuating the induction mechanism the chance of the incident to happen is reduced, and accordingly by extenuating an component of the unsafe belongings or mark and menace the badness of the incident will be reduced. These theoretical facets and categorization prove to be important in any undertaking refering jeopardy designation, extenuation, and hazard and impact appraisal. The basic construct of jeopardy theory can be summarized as follows ( C. A. Ericson, 2005 ) : Hazards are deterministic entities and non a random 1s ; Hazards are constituted accidentally in systems ; Hazards are predictable and hence can be controlled and prevented ; Hazards can be identified by their constituents ; Hazards will happen taking history of the constituents involved ; Hazards consequence in incidents. One of the term ‘s most recent definitions is the 1 offered in 2009 by the International Strategy for Disaster Reduction Secretariat: â€Å" a unsafe phenomenon, substance, human activity or status that may do loss of life, hurt or other wellness impacts, belongings harm, loss of supports and services, societal and economic break, or environmental harm. † As it can be noticed from the above-named definitions, jeopardy is characterized through certain parametric quantities, such as geographical location, strength ( magnitude ) , frequence and its chance to go on. In many of these definitions, one can detect the accent lies upon entropy, deficiency of determinacy and capriciousness ( Mac 2003 ) . In order to measure these phenomena ‘s possibility to go on, surveies refering their extreme values are considered. Furthermore, in all these definitions the construct of jeopardy has a instead negative intension, since it implies a certain grade of danger. Hazard can take the signifier of some remarkable phenomena or of some combines 1s, in footings of infinite and clip. Hazard appraisal purposes at identifying: the likeliness of a specified jeopardy to go on in the hereafter, in a certain period of clip, its magnitude and impact country ( Pine, 2009 ) . For the appraisal of certain jeopardies such as inundations, temblors and vents there are good established, predefined methods. The consequences of these ratings are extremely relevant in footings of lucubrating land usage planning schemes and in implementing accident bar steps.Hazard vs. hazardThe term â€Å" jeopardy † is closely related with the term â€Å" hazard † . Not few are the instances when confusion arises between the significances of these two constructs. This is why it is necessary to separate between them. Hazards are phenomena whose manifestations can barely be predicted and controlled. They have negative effects on population and on the environment. Imputing the characteristic of jeopardy to a natural or anthropic phenomenon is non conditioned by the production of mater ial harm or by the being of victims, but by the potency of these effects to go on. ( Baldea, 2007 ) . Merely when that jeopardy or phenomenon exceeds certain critical values, taking to material harm or casualties, does it go hazard. Therefore, a jeopardy is the menace that an event might go on and non the event itself. Should it impact a human community, to a certain extent, it becomes hazard. It must be mentioned that the term â€Å" hazard † is attributed assorted significances, being used in different contexts. Its definitions have societal, economic, political and environmental values. In order to better understand its deductions, a short diachronic analysis is necessary. To get down with, the term under treatment was foremost used in the fifteenth century, when it referred to the trade ‘s fiscal danger ( Proske, 2008 ) . Initially, this construct was associated with economic activities, being so used in the theory of chance and gaming. In the nineteenth century it is integrated in economic system, experiential doctrine and determination theory, whereas in the twentieth century it was used as political term in atomic engineering in order to gauge the degree of security that was acceptable for people. Until the 8th decennary of the old century constructs such as hazard, jeopardy and hazard direction were associated with natural phenomena. Hazard and natural or anthropic jeopardies analysis became an interdisciplinary kingdom of survey with its specific nomenclature merely in the last 30 old ages. The Longman Dictionary for Contemporary English, 2010, defines hazard as â€Å" the possibility that something bad, unpleasant, or unsafe may go on † . In 2007 ISDR defines hazard as â€Å" the combination of the chance of an event and its negative effects † . In 1999 Octavia Bogdan and Elena Niculescu define hazard as â€Å" the existent chance or possibility for a phenomenon to go on † . This event is someway expected and has negative reverberations, in response to which world can merely be inactive. Another definition is offered by Ozunu in 2000: â€Å" the chance that the existing jeopardy turns into an accident † . Alwang, 2001, cited by Thywissen, 2006, defines hazard as â€Å" the possible distribution of some known or unknown events. These are characterized by magnitude, frequence, continuance and history † . In the same twelvemonth, Peduzzi, cited by Brauch, 2005, considers risk aˆza step of possible losingss generated by a jeopardy of a certain magnitude, produced in a certain part and period of clip † . It must be stated that natural events can turn into social hazards when they surpass the immediate capacity of being counteracted or absorbed. They are, in most of the instances, utmost events. An utmost natural event is any event or series of events that shows a fleeting or durable fluctuation as compared to its common values. ( White, cited by ArmaAY , 2003 ) The widely accepted definition of hazard as the merchandise between the chance for an event to go on and the negative effects it may hold is expressed as follows: R= F x C ( Eq. 2.1 ) where: R- hazard ( losses/unit of clip ) , F- frequence of happening ( no. of events/unit of clip ) , C- effects ( losses/event ) . Hazard can besides be defined as â€Å" the chance of human exposure, of semisynthetic goods and of the environment to the action of a jeopardy of a certain magnitude and their exposure towards it † ( BA?lteanu, 2005 ) . For Petrea, 2009, hazard is â€Å" the possibility that some negative effects for human communities or losingss ( human lives, hurts, diminished agencies of subsistence, goods, harm of the environmental constituents ) appear as an interaction between natural or anthorpic jeopardies and territorial exposure † . This expression associates two distinguishable elements, viz. the jeopardy and the receiving system ( in most of the instances, a certain population ) . In most of the instances, the undermentioned expression is used: R= Hazard x Vulnerability ( Eq. 2.2 ) This underlines the relation between an event and its effects. In a certain country, the hazard is comparatively changeless. What differs is community exposure, in footings of its reaction to menaces or its degree of readiness to confront them. Harmonizing to the above-named expression, hazard may match to a high-frequency jeopardy and a low exposure or to a low-frequency jeopardy and high exposure. The disadvantage of this expression is that it does non see the population denseness, i.e. its exposure to hazard. Mitchell, 1990, cited by Brauch, 2005, completes this expression, sing jeopardy as a map of hazard, exposure, exposure and response: Hazard= degree Fahrenheit ( hazard ten exposure x exposure x response ) ( Eq. 2.3 ) where: hazard – the chance that negative effects appear, exposure – the size and characteristics of the open population, exposure – the potency of harm to bring forth and response refers to the enforced steps for hazard decrease. Another definition is given by Ozunu and Anghel in 2007: R = F x C x V ( Eq. 2.4 ) where: R – hazard ; F- frequence ; C – effects ; V- exposure ( – ) . The harm produced as a consequence of a catastrophe is really the consequence of the interaction among physical environmental factors ( clime, H2O, landscape etc. ) , population ( societal categories, civilization etc. ) and the built environment ( edifices, substructure etc. ) ( Mileti, 1999 ) . Therefore, jeopardy can be considered the pre-disaster state of affairs, when hazard does non look. A phenomenon ‘s development has three phases, more precisely: the jeopardy one, when merely hazard appears, the hazard phase, when jeopardy can impact human society and, eventually, the catastrophe. ( Alexander, 1993 ) In decision we can province that there are two types of hazards, viz. an acceptable one, where losingss are tolerable for the population and catastrophe, when losingss can non be tolerated by the local community.Categorization of jeopardies and hazardsAs antecedently mentioned, jeopardies and hazards are defined and characterized in multiple ways. In this chapter, a categorization is presented harmonizing to the most relevant features: beginning, effects, frequence, affected surface, etc.Categorization after beginningThe categorization of jeopardies harmonizing to their beginning is presented in table 2.1: Table 2.1 – Categorization after beginning ( BA?lteanu, 2005 ) :Natural jeopardiesEndogenousVolcanic eruptions, seismicityExogenousClimatic Cyclones, twister, storms, lightning, hail, hoar, drouth, etc. Geomorphologic Mass supplanting, eroding Hydrologic Flash-floods Oceanographic Rise of planetal ocean, El Nino Biological Epidemics, viruses, insect invasionsAnthropogenetic jeopardiesTechnologicalIndustrial, agricultural, transport accidentsHuman( Benedek, 2002 ) Social Poverty, unemployment, urbanisation, life style Medical Infectious, viral, chronic, degenerative diseases Demographic Emigration, population growing, aging of population Political Territorial, political differences2.3.2 Classification harmonizing to the manifestation mannerThe categorization of jeopardies harmonizing to their manifestation manner is presented in table 2.2 ( GoA?iu and Surdeanu, 2008 ) : Table 2.2 – Hazards categorization harmonizing to their manifestationViolent jeopardies– temblors – vents – severe storms, twister, etc. – local storms with hail etc. – catastrophic landslides, avalanchesHazards with progressive development– Mediterranean disturbances ( Mediterranean cyclones with retrograde development )Hazards with slow development– drouth – severe drouth – radiation and vaporization mists2.3.3 Categorization after continuanceHazards can besides be classified harmonizing to their temporal development. Harmonizing to ArmaAY , 2008 the categorization after the continuance of jeopardies is presented in table 2.3: Table 2.3 – Hazards categorization harmonizing to their continuanceWith sudden happening and rapid developmentEndogenous, tectonic jeopardies, sudden mass supplantings, flash – inundationsWith long continuanceTerrain debasement, drouths, desertification2.3.4 Categorization after affected surface, and continuance of effectsHazards can endanger assorted extents of a district. Within the affected surface the effects can prevail for assorted sums of clip. Harmonizing to Chardon, 1990 and Grecu, 1997 a categorization after the affected surface and the continuance of effects is presented in table 2.4: Table 2.4 – Hazards categorization harmonizing to affected surface and continuance of effectsCalamity typeAffected surfaceDuration of effectsExamplesGiga calamity100 – 510 mil. km2 several old ages volcanic eruptionsMega calamity1 – 100 mil. km2 several months big temblors volcanic eruptions tropical drouthsMeso calamity10.000 – 1.000.000 km2 several hebdomads – a few months volcanic eruptions temblors, cold moving ridges tropical stormsCalamity100 – 10.000 km2 a few hebdomads little temblors, twister exceeding rainsLocal phenomenaunder 100 km2 a few yearss – a few hebdomads landslides hail storms The present thesis focuses on the appraisal with optoelectronic engineerings of two major jeopardies from the above mentioned categorizations: Natural jeopardies – volcanic ash by active and inactive remote feeling Technological jeopardies – monitoring and patterning the impact of SO2 emanations associated with big burning workss.NATECH jeopardiesThis thesis focuses both on natural and anthropogenetic jeopardies individually. In order to develop efficient schemes for measuring hazards and impact, the NATECH ( natural jeopardies which trigger technological accidents ) rule is necessary to be considered when measuring either of the two above mentioned types of jeopardy. Current EU ordinances in the field of hazard appraisal and catastrophe direction ( European Commission, 2010 ) stress the necessity of a multi-risk and multi-hazard attack in all natural and anthropogenetic jeopardy and hazard surveies. Therefore, there is a turning involvement in the scientific community and among stakeholders sing natural jeopardies which trigger technological accidents ( NATECHs ) . NATECHs have important negative effects on human wellness, the environment and the economic system. The addition in the figure of such events is closely linked with the exponential technological development of the past decennaries, due to the variegation of engineerings, the turning figure of personal exposed, and the substances used in the technological procedures. The effects of NATECH events have become more terrible within this timeframe chiefly due to the exposure of the population life near these installations. Given these facts, there is an pressing demand for raising consciousness about bar and readiness steps refering these high effect low chance events ( Cruz and Okada, 2008 ) . Due to the complexness of NATECH events, their word picture is instead hard, and many NATECHs are analyzed and assessed as separate natural or technological events ( Embelton and Embelton-Hamann, 1997 ) . One needs to take into history that the effects of such an event differ in complexness from the effects of the two events taken individually ( Cruz and Krausmann, 2008 ) . Therefore, there is a demand for scientific research on the interactions and dealingss between natural jeopardies and technological accidents. Addressing NATECHs requires a combined attempt of industrial and technological hazard direction specializers working together with specializers concentrating on natural jeopardy probes. The specific features of a NATECH event ( Domino impacts, multiple effects ) need specific steps for the bar, response and recovery after such an event. An integrated hazard and impact direction scheme must include the possibility of NATECHs to happen, and necessitate specialised planning for extenuation, response, and recovery ( Ozunu et al. , 2011 ) The Activities Report On the Collaboration Agreement between the International Strategy for Disaster Reduction of the United Nations and the Directorate General Joint Research Center of the European Commission proposes a scheme for the extenuation of NATECH events by: iˆ Industry hazard direction specifically turn toing the possible impacts of natural jeopardies on technological installings. Additional hazard direction processs ( Figure 2.2 ) in order to cut down the exposure to NATECHs: the usage of excess safety systems, natural jeopardy resistant designs, guidelines to inform industry about NATECH planning, and strategic arrangement of risky substances inside a unit. Figure 2.2 – Catastrophe Management processs ( Torok et al. , 2009 ) Efficient Emergency planning, including bar and extenuation, and response planning for NATECHs at all degrees of authorities. The purpose of the Risk Analysis procedure is to cut down uncertainnesss by increasing safety degrees by developing more efficient Emergency Plans, offering immediate determinations, detailed, accurate and steady instructions ( ( Torok et al. , 2009 ) iˆ Land usage planning, as an of import tool for setting-up insularity margins in order to protect occupants populating near risky installations. ( Christou et al.,2006 quoted by Torok et Al. 2011c ) . Article 13 of the SEVESO III Directive ( Directive 2012/18/EU ) provinces that: â€Å" Member States shall guarantee that the aims of forestalling major accidents and restricting the effects of such accidents for human wellness and the environment are taken into history in their land-use policies or other relevant policies † Information and instruction of the populace, authorities bureaus and all stakeholders involved in exigency direction, including decision-makers. iˆ Public engagement in NATECH hazard decrease planning, in order to better understand the perceptual experience of the degree of the NATECH hazard and the degree at which this hazard is considered acceptable ( Ozunu et al. , 2011 )Qualitative and quantitative methods for placing jeopardies and measuring hazardsA systematic designation of possible environmental impacts atmospheric pollutants have, every bit good as a strict analysis of their magnitude is required. The intent of such a procedure can be divided in two major issues, on one manus to bring forth quantitatively accurate appraisal of peculiar hazard and a comprehensive list of possible environmental impacts, and on the other manus produce a principle for doing public policy determinations that is both good reasoned, and recognized as legitimate and acceptable by the socio-economical factors. A complex environmental impact appraisal ( EIA ) and hazard appraisal ( RA ) methodological analysis requires assorted sets of informations about beginning footings, emanations, imissions, exposure, local weather forecasting, terrain informations etc.. Most of the air scattering theoretical accounts have been developed for the anticipation of lee concentration of air pollutants and for the appraisal of short-run and medium-term effects of these pollutants. The quality of consequences obtained utilizing these patterning systems depend largely on the versatility and quality of input informations and the right pick of the theoretical account ( Torok et al. , 2011a ) . In instance of EIA surveies, the medium-term effects appraisal requires emanation and meteoric informations for several months in order to obtain a realistic distribution of the largely contaminated countries. The consequence of the complex terrain on the air motion in the commixture bed is important. Therefore the meteoric information for the modeling period should be calculated sing the air flow above the complex terrain. For RA, the appraisal of immediate effects of ague exposure requires on-site informations for a short clip period. These informations sets must incorporate information about emitted substances ( type and concentration ) every bit good as real-time local meteorological informations, which along with terrain informations can be used in a rapid environmental and risk appraisal, which is a valuable tool for on-site exigency planning in instance of accidental or deliberated releases of toxic substances in the ambiance ( Torok et al. , 2011a ) . In the field of hazard analysis and hazard appraisal there are differences of sentiment sing the usage of qualitative or quantitative hazard analysis methods. The qualitative-quantitative factor is the basic belongings of jeopardies analyses methods. Most of the analysis methods are developed in order to place jeopardies and to find the hazard of that jeopardy turning into an accident. For finding the accident hazard of the identified jeopardy, a methodological analysis for the word picture of chance and magnitude parametric quantities must be used. There were developed both qualitative and quantitative methods, which are successfully used, each methods holding its specific advantages and disadvantages ( Torok et al. , 2011a ) .Qualitative methods used in jeopardy analysisA qualitative analysis implies the usage of qualitative standards, utilizing different classs for parametric quantities separation, with qualitative definition which set up the graduated table for each class. Besides, qualitative determinations are made, based on the field experience, in order to delegate elements into classs. This attack is subjective, but it allows a higher generalisation grade, being less restrictive.2.5.1.1 Designation of jeopardiesThe designation of technological jeopardies is the basic measure in hazard appraisal procedure. Hazards appear in the industry all the clip, due to the procedure and runing conditions of the installings and the physical, chemical and toxicological belongingss of the substances used in these procedures. This is why it is extremely of import to place the substances ‘ risky belongingss and the operating conditions that put at hazard these procedures, the series of events that may take to the materialisation of a jeopardy. In order to develop an in-depth survey of jeopardies and hazard analysis, the risky belongingss of the substances must be identified and assessed in order to find conditions or non they pose a jeopardy to human life, the environment of the technological procedure. From a qualitative point of position this can be achieved utilizing checklists. A comprehensive checklist used in the appraisal of jeopardies and hazards posed by substances is presented in table 2.5: Table 2.5 – Hazardous belongingss of substances- Checklist ( Hyatt, 2003 )TypePropertyGeneral belongingssMolecular construction Freezing point Melting point Vapour force per unit area Boiling temperature Critical force per unit area Critical temperature Critical volume Density Specific heat Viscosity Thermal conduction Fluid denseness Latent vaporisation heat Dielectric invariable Electric conductionFlammabilityExplosion/ Flammability bounds Explosion threshold Auto ignition temperature Minimal ignition energy OverheatingCorrosionCorrosive for building stuffs Incompatibility with other stuffsPolymerizationDecompositionFeatures of polymerisation Features of decomposition Features of hydrolysisImpuritiesImpurities in equipment stuffs Impurities in substanceChemical reactions, detonationsHeat of formation Heat of decomposition Combustion heat Thermal stableness Resistance to impact Potential energy jeopardiesToxicityExposure bounds: IDLH ; ERPG1-2-3 ; AEGL 1-2-3 ; LC50 and LD50 Exposure effects ( inspiration, consumption, tegument and oculus contact ) Effectss of long-run exposure with little sums Warning bounds ( odor threshold )RadiationRadiation bounds I ± , I? , I? atoms Material toxicity It must be stated that stuff toxicity depends on a series of physical and chemical factors, in the type of contact and on the interaction of substances with beings. The ways in which this penetrates the organic structure are assorted, viz. unwritten ( through the oral cavity, in the tummy ) , cuticular ( toxicity enters the tegument ) or by agencies of inspiration ( through the respiratory system ) . The harmful belongingss of risky substances can be divided into the undermentioned classs ( Ozunu and Anghel, 2007 ) : acute toxicity ( really toxic, toxic, harmful, annoying ) specific belongingss ( allergic, carcinogenic, with consequence on reproduction or familial consequence ) with harmful impact on the environment Whereas the first two classs mentioned supra have direct inauspicious consequence on wellness, the last one acts indirectly on human existences by damaging the environment. The harmful actions start when little sums of substances appear in the organic structure ; should larger sums appear, they can take to one ‘s decease. The most normally used indexs to find substance toxicity are ( Torok et al. , 2011c ) : medium deadly dose- LD50 is the dosage at which half of the experimental population of animate beings ( or worlds, should human deceases be registered ) dice. LD50 index at consumption and at the skin degree is shown in milligram ( mgs ) of substance per kg of animate being organic structure, taking into history a individual disposal. the medium deadly concentration – LC50: concentration for inspiration is measured in mgs of substance per litre of air breathed or in volumetric parts per million -ppm ( exposure clip differs depending on substance toxicity ) the immediate unsafe concentration for life and wellness – IDLH is inspiration with irreversible effects on wellness These bounds of concentration are used as indexs in both the US and the EU statute law ( NIOSH, 2012 ) . The bounds of toxicity for a series of substances are set in the Dangerous Substances Directive 67/548/ EEC. They are grouped harmonizing to some classs presented below. Each type of danger has a hazard phrase ( Rphrase ) consisting of a figure and of the appropriate hazard description ( Ozunu and Anghel, 2007 ; Directive 67/548/ EEC ) . Table 2.6 – LD50 ( unwritten )ClassLD50( mg/kg )SymbolRphraseVery toxic& lt ; 25 T+ R26, R27, R28Toxic25 – 200 Thymine R23, R24, R25Harmful200 – 2000 Xn R20, R21, R25 The current thesis focal points on two major jeopardies, natural 1s, with a instance survey on volcanic ash, and anthropogenetic 1s, with instance surveies on S dioxide ( SO2 ) . Sing volcanic ash, the most serious jeopardies can be associated with its: caustic belongingss on stuffs, i.e. aircraft engines, windscreens, etc. , runing point, the volcanic ash runing inside the turbine due to the high temperatures, and so solidifies in the ice chest parts of the engine s. denseness, the denseness of volcanic ash is comparatively high, dry ash being up to 5 times, wet ash about 20 times denser than snow. This fact represents a major jeopardy to edifices when ash accumulates on the roofs in sufficient measures, taking to prostrations. In the instance of SO2, the major jeopardies are associated with:Quantitative methods used in hazard appraisalQuantitative analysis implies the usage of numerical or quantitative informations and provides quantitative consequences. This attack is more nonsubjective and more precise. It must be mentioned that the quantitative consequences can be extremely affected by the preciseness and cogency of the input parametric quantities. Therefore, the quantitative consequences within the hazard analyses should non be taken into consideration as exact Numberss, but as estimations, with a variable graduated table depending on informations quality ( Torok, 2010 ) .2.4.2.1. ModelingThe representation of world through mold is extremely relevant, since it offers one the possibility to analyze and analyze systems in footings of mathematics and technology. It must be mentioned that a system consists of a set of elements that interact with one another within some bounds. Furthermore, this system has a specific behavior. These bounds are really the 1s that separate the system from the other 1s. These theoretical accounts can be divided into two classs, viz. physical and abstract ( fanciful or mathematical ) theoretical accounts. With respect to the physical theoretical accounts, they describe the system from a physical point of position, utilizing the physical Torahs that apply upon the system under treatment. The mathematical theoretical account of a system describes it in footings of mathematical equations, utilizing simplifying hypotheses. Abstractization works in both ways, i.e. from object to its representation ( theoretical account ) and so back to world. Still, it must be stated that this theoretical account does non picture world all the clip ; it tries to be as closer to it as possible. The more complex a system is, the more complicated the theoretical account becomes. In this context, the purpose of patterning systems and processes utilizing the computing machine is to make a theoretical account that contains a description realistic plenty for the given application. The basic stairss for the accomplishment of a mathematical theoretical account are as follows ( Savii and Savii, 2000 ) : job designation and the pick of variables building of mathematical dealingss among variables utilizing simplifying premises the purchase of information sing the size, importance and interrelatednesss for each variable under treatment the choice of input signals ‘ parametric quantities constitution of province variables proof of premises and dealingss utilizing the right theoretical account harmonizing to the state of affairs.2.4.2.2. SimulationWith the development of information engineering and computation equipment, the scrutiny of theoretical accounts utilizing simulations has become possible. Simulation allows proving those systems ‘ functionality theoretical accounts that have yet to be or are presently in design stage. Simulation is the lone possibility of analyzing the dynamic behavior of such a theoretical account. Discrete simulation, utilizing theoretical accounts of distinct systems, is of great aid for projecting production systems, where issues of optimisation appear ( Savii and Savii, 2000 ) . In the present thesis we focus chiefly on the mathematical mold of the gas pollutants ‘ scattering in the ambiance. Beginning theoretical accounts are used to specify the quantitative emanation scenario of substances by gauging their flow rate, the scattering of substance after release. Dispersion theoretical accounts turn the end products from beginning theoretical accounts into isoconcentration curves specifying concentration countries and cipher the development of concentration in clip. The mass conveyance of molecular-scale fluid occurs through diffusion, with a changeless diffusion velocity throughout its motion. However, unstable scattering is a procedure different from molecular diffusion, since the mass conveyance occurs at assorted scale lengths of the disruptive motion. Disruptive scattering is much more efficient than molecular diffusion. The scattering rate is non changeless ; it depends on the size of the whirl and of that of the cloud of spread pollutant. These whirls can be of different sizes ; on a big graduated table, they determine the motion of the pollutant cloud, whereas on a little graduated table they contribute to its dilution. The energy and size of these whirls determine gas plumes scattering. Their continuance, length and strength are the chief factors that influence this procedure. The mathematical mold of gas pollutants in the ambiance is based on equations of mass, energy and impulse preservation. Such an equation must be established for each pollutant. It represents the fluctuation of atoms ‘ denseness in clip and infinite. From these equations one can acquire a complex system of equations that can be solved by agencies of numerical methods, obtaining the existent behavior of concentration in clip and infinite. A literature reappraisal reveals two chief methods used for picturing the behavior of pollutants released into the ambiance, viz. the Eulerian formalism and the Lagrangian 1. Both methods are used to depict the statistical belongingss of pollutant concentration. The Eulerian formalism starts from ciphering fluid speeds in the ten, Y and omega waies, measured in fixed points in the fluid under treatment. Input information is comparatively easy to obtain from the measuring or mold of discharges, but work outing the mathematical equations system can be really complex, ensuing in inaccurate solutions. Dispersion coefficients can be retrieved utilizing the Pasquill-Gifford graduated table ( Pasquill, 1961 ) . After this, the imission map for a beginning point and meteoric scenario can be developed. The Lagrangian formalism uses the statistical belongingss of some fluid atoms that move passively, freely. As compared to the Eulerian formalism, the mathematical equations system is easier to work out, therefore it is computationally really efficient, and merely the fraction of the sphere really involved in the scattering is simulated. Disruptive procedures are included in the theoretical account in a more natural manner, and there is no important numerical diffusion ( Stohl et al. , 2005 ) . Still, the method ‘s pertinence is limited by the troubles encountered when finding the statistics of fluid atoms. The Lagrangian formalism is applicable upon long-distance scatterings, when the complex topography influences the flow of air-pollutant multitudes. Although the scattering procedure is a typically Lagrangian one, about all information available refering the ambiance are based on Eulerian measurings. Therefore, a relation between the Eulerian belongingss and the Lagrangian 1s is ( widely ) accepted ( Sandu et al. , 2004 ) .

Research Paper about Lockers

We really appreciate their presence because without them, we would not be able to improve our research paper. Last but not the least, is our loving and forgiving heavenly Father for giving us knowledge, wisdom and a lot of things we need to make for the completion Of this research possible. Introduction Most students nowadays prefer to do things in haste and in the easiest way, not thinking the consequences they could bring. During schooldays, students prefer to use sling bags instead of using backpacks. That is why they come to the point that they demand a locker, so they can secure their valuables at school.Through this, students would either gain or lose trust to others when leaving their things in their own lockers, not knowing what might happen when they are not around. On the other hand, they would also develop a sense of responsibility in maintaining the cleanliness and security of their own gadgets and school paraphernalia entrusted to them. Lockers are designed for the secur ity of valuable things they often bring at school. Lockers in International Christian School of Dave [ICED] are being criticized by both students and teachers not knowing that this facility could change meson's perspective.Statement of the Problem The main purpose of this research is to help the students know the significance of a simple storage box they call as locker. This one significant locker can be the source of mode in their studies. The following questions must be answered after conducting the research: 1 . Why locker is considered important? 2. What are the suggestions or demands for the improvement of lockers? Objectives of the Research TO determine the importance Of lockers for students To know the students' opinion regarding the improvement of lockers Significance of the ResearchThis research will help the problem of students through high percentage of having back and neck pains. In addition, this will also reduce the chances of students leaving their learning tools at h ome. Scopes and Limitations This research focuses on the gathered data based from the answers of all students in International Christian School of Dave who use lockers. This also focuses on the significance of locker and why it is considered as an important matter to be discussed. Definition of Terms 1 . Locker – normally quite narrow, of varying heights and tier arrangements.It is usually equipped with a lock. It is usually intended for the short or long term private use of individuals for storing clothing or other personal items 2. Self storage – an industry in which storage space such as room or locker is rented to tenants, usually on a short-term basis Review of Related Literature Lockers are usually a small storage component customarily shaped as a rectangle and is metal, which simply designed for leaving stuffs with security. Usually, it's a single tier or two tiers. Every locker is never without its padlock or lock combinations.Lockers are usually placed besides the hallway and are found together with the other lockers in the row. Crisp, 2011) In the busy schedule of students due to their projects, assignments, or seat works, lockers are absolutely a necessity for most of them. It is also a very good place to stock valuable stuffs (mostly cellular phones, gadgets, lunches, extra money, emergency shirts, and other school stuffs) because they can get the privacy and security they want depending on how they use it and how they organize it.Most schools usually managed to set the number of lockers depending on the total student population they are expecting or they need, and is usually more affordable depending on its size but most likely pending on the school's finance management. (Proponents, 2013) Some students agreed that, locker is important and provided some known benefits in having them. However, the opposing party said locker is not necessary to have and provided its disadvantages.Here some of those explanations given: Disadvantages of Having a Locker Cannot refer on the Books at home while it's left on the locker Leaving books on the school locker is not a very good thing to do. Students won't be able to refer on their books for assignments and obviously wont be able to study some lessons ahead of time, which most likely causes them to ratiocinate. (Chelsea, 2007) Get in the crowd during dismissal time Instead of going directly to their classrooms or going straight home, they still need to go to their locker with the other students who are also busy with their lockers or just people talking in the hallway.This might also cause students or even teachers from being late to their classes. (Chelsea, 2007) Problems with the Locks Students always encounter this kind of issue because of misplacing their keys or forgetting their password combinations. This would be a pain in the neck especially when your lock is very hard to be pick or jam. Chelsea, 2007) Foods Left behind will Spoil Some students still left their lunch boxes (if they bring one) in their lockers. They find it disturbing or think it might be a bother if they bring it around all day.Bad thing is there's a possibility they might left it Or forgot about it which causes the food to spoil and might create mold and smells in the hallway especially leftovers. (Chelsea, 2007) Can be Stored for some Illegal Objects Teenagers these days, especially boys, tend to think that being a goon makes them look cooler. And about most of them brings deadly or prohibited paeans or objects in school. These objects includes: guns, knife, mini tool kit, illegal drugs, pornography materials, and other things related to it.In United States, the National Education Association (NEE) is performing locker searches every weekend to ensure the safeness of all the students and school staffs. It was to make sure everything in the locker is not harmful or not against the rules and regulations of NEE and the school itself. However, in Philippines, there are no known po licies or regulation about things to be considered in having a locker. (Cornell, 2013) Advantages in Having a Locker Doesn't need to carry heavy bags Children and teenagers should not carry backpacks which weigh about more than 15% of their respective body weights.It can affect the movement of our spines and may cause musculoskeletal problems that the books students carry are getting thicker which means getting heavier. In this students must have. (Patella, 2013) Won't leave the books at home The students have a locker does not mean they do not need to bring their books at home. It is much better to bring those books you just really need so you will just have lighter things to carry in the next school day. Also, in leaving hose others books at your locker, at least would not forgot to bring your book when there are surprise activities, readings or seawater. Patella, 2013) Safe Storage Everything you have on your locker is only safe when you protected it with a durable lock. Lockers are the only known safest place in where the students can put their things when they are in school, especially when bringing things such as musical instruments, props, and other equipment you really need. Though, this would only work on bigger lockers. Which means the school should consider the size of the lockers basing on the programs and different lubes which needed some individual equipment. Patella, 2013) Developing Responsibilities Everything a student put in his/her locker is all the students' responsibility, on how to keep the lockers safe and how to maintain it. By having a locker, a student will be able to develop his/her responsibilities in things such as organizing, memorizing the password combination or keeping in-mind in bringing the key, and being a able to manage him/herself in. This teaches students about social responsibility and etiquette. (Spineless, 2013) Time Management Managing time is Very important especially in the student's education.One just manage time, never waste it, and make plans for something that is relevant to the future. Just like in having a locker, the students need to manage their time on taking and putting books back in forth in their lockers after every class or breaks. This will prevent them from being late. (Spineless, 2013) Heavy Bags Children and teenagers are still in the developing stage of their body. It is advisable that if possible, only 15% percent of our body should be the limit of the things we carry. Counterpart would cause injuries to the body. These injuries include back pains, neck pains, shoulder strain, and general exhaustion.Patella, 201 3) Larger Lockers Most students in every institution demand a larger locker in which the things they mostly use in school wouldn't need an extra space in their classroom. This would let them bring heavy or large necessary things in school. This would also let them have personal things in their locker too. However, this would take up space in school on which is only l imited. Also, smaller locker sizes are intended to limit the students from being Irresponsible for their lockers. (Kevin, 201 1) Locker Searches Teenagers these days can be very violent. We never know that they have been bringing illegal items to their schools.There are already guilty students that have been found bringing illegal items at school such as guns, illegal drugs, and other deadly weapons; which merely means that this Locker Search policy is very helpful and needed in every school. Locker Searches is scheduled every month in school, assigned persons were tasked to perform an investigation in each lockers in a school and makes sure there are no illegal things inside it. Policy 1005 â€Å"School Locker Use and Locker Searches† which is signed last November 20, 2004 and first implemented by the Yukon Education Public School Branch and now spreading across the world.It is not, forever, yet implemented in the Philippines and there is also no known policy or law against freedom use of lockers. (Moore, 2004) Data Gathering All of the ICED high school students who rent a locker were asked to answer the 8 questions we formulated. This was to know their opinions and thoughts about the main topic of this research. 1. For you, what is the advantage of having a locker? Body would not suffer for carrying lots of stuffs Stuffs would not be left at home and would come in handy when needed during classes Organize the personal space with your own stuff 2.For you, what is the disadvantage of having a locker? Cannot study when books are left at school People can break into it and steal your stuffs Provides a place in keeping concealed weapons and other illegal materials 3. What stuff do you generally put in the locker? Books – Clothes 4. Do you feel that the things in your locker are secured? Yes – No 5. Does the locker's price fit its size? 6. Is the locker expensive or affordable? Expensive – Affordable 7. Is there anything you want to sug gest for the improvement of the lockers?Bigger locker that fit with its price- Affordable price – Bigger lockers 8. What is your main purpose of having a locker? Reduce weight Of baggage Safe storage – personal space Interpretation of Data 1. For you, what is the advantage of having a locker? Based from the survey conducted, 12% or 6 out of 50 persons believe that an advantage in using a locker is being able to organize the personal space with their own stuffs. 24% or 12 out of 50 persons believe that another advantage in using a locker is that their stuffs would not be left at home and would come in handy when needed during classes.A 64% or 32 out of 50 persons, which is the majority of the students who were surveyed, believe that using a locker would not let their body suffer from carrying lots of stuffs which may cause ace and neck pains. Based from the survey conducted, 6% or 3 out of 50 persons believe that a disadvantage in using a locker is that it provides a pl ace in keeping concealed weapons and other illegal materials. 28% or 14 out of 50 persons believe that another disadvantage in using a locker is the tendency that people can break into the lockers and steal their stuffs.A 66% or 33 out of 50 persons, which is the majority of the students who were surveyed, doubt to have a locker for it can be a cause for students not to be able to study because of the tendency that their books would be left inside the locker. 3. What stuff do you generally put in your locker? Based from the survey conducted, 4% or 2 out of 50 persons put clothes inside their lockers. On the other hand, 96% or 48 out of 50 persons put books inside their lockers so that they may lessen their baggage when going to school.Based from the survey conducted, 40% or 20 out of 50 persons feel that their things in the locker are not secured since some of the lockers do not have locks. On the contrary, 60% or 30 out of 50 persons believe that the things in their locker are abso lutely secured. Based from the survey conducted, 24% or 12 out of 50 persons believe that he locker's price just fits its size. On the other hand, 76% or 38 out of 50 persons believe that the locker's price does not fit its size because the price is totally expensive, but the lockers space is too small.Based from the survey conducted, 24% or 12 out of 50 persons find the lockers affordable while 76% or 38 out of 50 persons find the lockers expensive to be used for only one school year. Based from the survey conducted, 6% or 3 out of 50 persons want to have bigger lockers because they want to have single or double tier lockers. 34% or 17 out of 50 persons want to have lockers with affordable price. Lastly, 60% or 0 out of 50 persons want to have both bigger and affordable lockers. 8. What is your main purpose of having a locker?Based from the survey conducted, 12% or 6 out of 50 persons wanted to have a locker for personal space which is used to keep all their materials needed at sch ool. 28% or 14 out of 50 persons wanted to have a locker for safe storage. A 60% or 30 out of 50 person, which is the majority of the students who were surveyed, wanted to have a locker to reduce the weight of baggage that may cause misalignments of bones, back and neck pains. Conclusion Most of the students in ICED think that locker is absolutely important because t provides personal space for each student.In addition, it would lessen back and neck pains caused by carrying heavy baggage. However, the students suggest that changes should be pertaining to the lockers. First, the students demand for a bigger locker so that they would be able to put things such as musical instruments, props and sports equipments in it. Second, the students demand for much affordable price that fit with the locker's size which means the price should be acceptable with its own size. Third, the students demand that each locker should have a lock so that they would be able to use their lockers for the enti re school year.

Using internet newsgroups for online market research Paper

Using internet newsgroups for online market - Research Paper Example It is also through these groups that I will be able to relay information about how easy and convenient it is to access my boots. Being an active member in forums and contributing to important topics will play a major role in establishing links and good relationships. Through discussions and frequently asked questions, I will be able to know people’s likes and preferences as well as the challenges they encounter trying to access business services. This way, I will have the ability to adopt the best marketing strategies that are more appealing to the people and that are likely to increase sales. There are discussion groups that will allow me to advertise my products. This will give me an opportunity to attract potential buyers specifically by insisting on affordability and comfort of my boots. There are various ethical principles that I might violate if I use messages from newsgroups however much it may be difficult to distinguish private space from public space on the internet. For instance, I might violate the principle of ownership. Collecting information and claiming false ownership is unethical. The principle of acquisition might also be violated. Acquiring and using information without the owner’s consent is unethical. Another principle is the principle of identity. Providing false identity so as to acquire permission to use information is ethically inappropriate. The principle of accountability might also be at stake. A person is expected to be accountable for any situation that may arise as a result of using message that he/she did not publish (Josephson, 2010). In my view, there is no ethical problem in using newsgroups for marketing purposes or using messages from discussion forums. According to me, ethical problems are only applicable in most internet related activities if content is used for the wrong reasons such as

What does the surviving evidence from Pompeii suggest about the ways Essay

What does the surviving evidence from Pompeii suggest about the ways in which Pompeians spent their time - Essay Example Vesuvius to have been recorded. In 1748, it is when staid excavations start and since then, it has been a tourist trap. Besides, all learning institutions are teaching of this city, with each and every other individual having the desire to make a visit. The historian might be better positioned in eloquently waxing how Pompeii is a city â€Å"frozen in time† as well as how the eruption turned out to be a blessing in disguise to the generation of the present time. On the contrary, the Romans had a totally different view of the destruction of Pompeii and the neighboring cities. In their viewpoint, this eruption was among the worst ever natural disaster to have ever occurred in the history of the world. It is believed that things would have been worse (Cooper 1). Despite the fact that modern day newspaper stories report that twenty thousand people passed on during this eruption, the exact figure of the people who lived there is hardly known. The 20,000 figure is seemingly the most common figure availed, but other sources have the same figure 10,000 lower. Either way, the agreeable guess figure is that over 35000 people died and in Pompeii alone, between 1600 and 2000 were trapped in the eruption. What remains is the surviving evidence to tell us how the situation was like (Cooper 1). The surviving evidence presents us with one of the very best glimpses of what the everyday life was like in a Roman city. Being a resort town as well as a center of commerce, the surviving evidence depicts how the rich in the society had come to this town so as to free themselves from the hassles of living in Rome, and ships put into the Bay of Naples from all corners of the globe. In addition, the surviving evidence presents both the aura and the prosperity of e njoyment that seems to have been in prevalence (Maiuri and Battaglia 652). These two (the prosperity and the aura of enjoyment) have hardly been shared in any other of the workaday towns. From this evidence, we are lured to believe that hardly was there peace and harmony in Pompeii. By the virtue of there being an excess of the rich in the society it is probable that there was a big-me/little-you division with the ordinary town folks. Tis same scenario was in Rome and from the judgment of how things are as regards to what was left, the inhabitants of Pompeii undeniably knew very well how to enjoy themselves (Gore 556). It is worth noting that historians may not be totally certain of the number of days in each of the Roman Months. The thought of these historians is that the roman months just resemble ours, though there is enough uncertainty for any given date to be off by a couple of days. The surviving evidence also testifies that the Pompeians rose up early in the morning, as is th e case with the present Romans. Besides, it can be told from the very first glance that they were respectable middle class persons. If this was not the case, there would have been an evidence of a slave waking then up and probably helping them dress. This may actually sound somewhat strange since the Pompeian’s’ clothes, from the surviving evidence, were unpretentious in the extreme (Harris 56). For each and every Roman national, irrespective of whether poor, middle class or rich, tunic was the main piece of clothing. Having been made of wool, the tunic was simply a two-square piece cloth sewn together, with holes having been left for the arms and the head. From the surviving evidence, the tunic- having been as wide as it was broad hung loosely on all but the heftiest frame. Moreover, the cut had been made in such a way that the excess clothe did form sleeves of a sort, with its appearance resembling a long shirt dropping somewhere between the calf and the

Population and migration Essay Example | Topics and Well Written Essays - 250 words

Population and migration - Essay Example The development of the mega-cities is immense as research shows that the megacities hold the richest 25 cities in the world. The endless city covers a small fraction of less that 18% of the world’s population but account for more than 66% of all the economic activities and more than 80% technology and scientific innovations, which is crucial to economic growth (Snarr & Snarr, 78). I support Neo-Malthusian because there has been immense growth of population over the years that have surpassed supply increase leading to catastrophic checks in the people. Without population control, the people will diminish by catastrophes such as drought or war (Snarr 44). To resolve this problem, the world should join and urge people to control population by using measures such as sterilization, abstinence, among others. China for instance, has introduced punishment for people who bear more than one child as the country is facing population overgrowth and many parents can barely support the children they

Nuclear Power and Solar Power Essay Example | Topics and Well Written Essays - 500 words

Nuclear Power and Solar Power - Essay Example In a nuclear power station, the element uranium is applied in the process of producing nuclear power. The process of producing nuclear energy takes place in a nuclear reactor. In the nuclear reactor, the fuel used is uranium rods, and through nuclear fission, heat is generated. Heat in the nuclear core is generated when neutrons split in half after shattering into nucleus of the uranium atoms. Thereafter, water is passed through the heat, and as a result, steam, which drives turbines, is produced. Generators, connected to these turbines produce electricity (Petersons 23). It is also possible to produce nuclear energy via fusion. Fusion generally utilizes tritium or deuterium as a fuel, while recent advances have seen boron and lithium used. This process is, however , is expensive and complex thus has yet to be utilized commercially. Spent nuclear fuel can be assimilated into fuels of mixed oxides, and this is done in large scale, in France and Britain (Petersons 34). However, France, the most efficient of the assimilators, only reprocesses 28% of fuel used yearly. In a solar plant, sunlight is converted to electric energy via PV or CSP. CSP or concentrated solar power utilizes lenses and systems for tracking in order to focus large sunlight areas into smaller beams (Petersons 52). PV or Photovoltaics utilize Photoelectric effect to convert sunlight into energy, which is electricity. Commercial CSP plants were established commercially in the 1980s (Petersons 54). PV has been utilized since the 1860,s after fears on the â€Å"foreseeable† shortage of coal. Rationally, the facts are stacked in favor of solar energy. Recent studies by NC WARN show that costs related to nuclear energy are going up with the most recent estimate being 20 ¢$/kwh, while costs related to solar energy are going down, recently estimated at 15.9 ¢/kwh, before transmission charges at the site (Petersons

The Circle Essay Example | Topics and Well Written Essays - 1500 words

The Circle - Essay Example The images and sounds are equally pitiful and terrifying for the viewer. In quick summary, the movie begins with a miraculous event- the birth of a child. Unfortunately, the joy never follows because the child is a girl, even though the doctors told the family it would be a boy. Then the viewers meet Arezou and Nargess who have escaped from prison. They try to find their way to what they hope might be a country paradise. Another woman, Pari, is pregnant, but since her husband has been executed, she cannot get approval for an abortion. She is trying desperately to get one anyway. Yet another woman is trying to abandon her young daughter with the hopes that another family will take pity on her and give her a happy home. A prostitute, a luckily remarried woman, and a woman whose husband remarried while she was in prison round out the cast. It should be noted that the cast was not one of Hollywood starts, but of real Middle Eastern women. This lends a feel of authenticity and reality to the film. All of the women in director Jafar Panahi's film suffer from two things: their gender and their marital status. Single females in Iran are open to torturous and demeaning treatment every day. Their dress, travel, work, and hobbies are all subject to male approval. Their struggles are incomprehensible to women in the western world who alternate between voicing dismay at their plight and conveniently avoiding it. For these reasons. Panahi's film stings so deeply into the cores of viewers everywhere, especially women. Western society cannot understand, let alone justify, these treatments of women. Fortunately, two Middle Eastern women can provide explanations about the substance of this film as it relates to life for women in Tehran and the Middle East as a whole. Suad Joseph is currently a Professor of Anthropology of Women and Gender Studies and the Director of Middle East/South Asia Studies at the University of California at Davis. She is a native of Lebanon and has spent years researching women, family and children in her native land. Her research focuses on their concepts of self, citizenship and rights. She has written several books on the subject including Gender and Citizenship in the Middle East and Intimate Selving in Arab Families. She is the founder of the Association for Middle East Women Studies and of four American universities in the Middle East. Shemeem Burney Abbas is a native of Saudi Arabia. She has taught at colleges in both Islamabad and in Texas. She spent the years from 1987 to 1992 at the University of Austin in Texas and then at the Allama Iqbal Open University in Islamabad from 1992-1999 and then again from 2002-2003. She has given lecture of her article "The Female Voices in Sufi Ritual: An Ethnography of Speaking at the University of Texas, the University of North Carolina, Duke University, Columbia University, and the University of Pennsylvania in the United States. She currently holds a Ph.D. in English Language. According to Joseph, in Gender Citizenship in the Middle East, an examination of the legal documents related to citizenship has revealed that citizenship is extremely gendered in all arenas, particularly the political, economic and cultural. Joseph argues that the struggle for women to gain a sense of self and identity through citizenship has been compromised by the nations' struggles for identity themselves. The nations of the Middle East, on

SOP Essay Example | Topics and Well Written Essays - 1000 words

SOP - Essay Example I worked in the Jeddah office for a little over a year in the sales department. There, my core job was to help the customers get the best health insurance for them and their families. After my stint with the Insurance Company, I joined Samba Financial Group, where I worked in the customer service department for two years. This job required me to provide satisfactory explanation to many questions posed by customers about all the products and services we offer. The experience I gained by working for these organizations made me realize that I love helping people, and created a strong inclination in me towards finding self-fulfillment in helping others. All my life I have been encountering injustice in the treatment of people with disabilities in my country, that’s precisely why I want to work in the public sector and run programs to raise awareness for people with special needs in order for me to contribute to society. Society has given me so much and it is just about time for me to give something back to the society. After working those five years in different jobs I found myself developing and helping others gain the most value from the products and services I sold them, and I changed my mind about what had been built in it from the Saudi society that all women are not aim to work and give. In Saudi Arabia we have to wait for marriage and live under the wings of a man and cannot be independent, which made me careless when I was in college and didn’t care about my grades. In June 2010 I shifted my base to the United States and am presently pursuing proficient level English courses at EC Boston. Since the time I have come to the US I have noticed that people with disability are independent and living as there is nothing can stop them from enjoying their life and I find this amazing, I have learned a lot from such people. They are the epitome of courage and dedication, And that is totally different from how it is in Saudi Arabia, which

Long Term Impact of Parental Divorce Essay Example for Free

Long Term Impact of Parental Divorce Essay This is an interesting study about how divorce can affect adulthood. At the age of sixteen, all students from one town completed a questionnaire. All the students were given a follow up questionnaire at thirty two years of age. Coming from a divorced family affects women more than men. This could be because of the close relationship between mother and daughter. Several studies have showed that parental divorce increases the risk of divorce for offspring. Children that have divorced parents have a lower self-esteem than those who do not. Divorce negatively affects children in the personal and social development in adolescence, which reduces the quality of intimate relationships in adulthood. The reason the quality of intimate relationships are lowered, is because parent-child relationships have been found to play an important role in perceptions of social support in adulthood. Many women have big issues with the trust factor that needs to accompany an intimate relationship. Women are less likely to get married, and the women that do marry are more likely to get divorced. This does not affect boys as much because boys do not need the parent-child relationship as much as girls. If doing a research paper on the topic of social development in adulthood, this would be a good article to get information. The article is a peer reviewed journal, making it a reliable source. The study was also done over a long period of time. It is important for other to see how divorce parents could be having an effect on their social development as an adult. Many women may not see the significant coming from divorced parents maybe affecting their relationships in adulthood. This journal along with other could only give a better look into problems in social development in adulthood.

Technology Means The Study Of Something Sociology Essay

Technology Means The Study Of Something Sociology Essay The word technology is the Greek word and its means the study of something, or the branch of knowledge of a discipline. Technology is the knowledge about tools, systems and many more. Technology changes the life style of the world and we are now considered as technical world. Technology is now in big demand and its reaches on the peak height but still people wants new and new technology. The great saints said everything has its two sides similarly technology has merits and demerits. Technology provides the people now life to think wide and able to prove that things.Technology decreases the death rate and able to do that surgeries which earlier not possible. Now we heard that now the 3d televisions are about to come. We is going on it does not matter whether we are sleeping or not. Technology makes the life fast and the work which we do the work with much time earlier and its is done in minutes. An ever transport makes the whole world close to each and take less time to travel. Education, social life, every electric things show the advancement in the technology. Now Talked about the demerits of technology, it makes the life machine porn and makes us more lazy. We are going away from the nature and the respect towards the nature is declining.We are now only thinking for ourselves, the love towards humanity is vanished earlier we have that.So in the conclusion we can say that technology makes our life easy and technical but it forms a path which ends on destruction. Everything that provides us lots of things like comfort, easy and many other it must be in limit. Limited things always create wonders. Jaspreet Singh Technology, general term for the processes by which human beings fashion tools and machines to increase their control and understanding of the material environment. Many historians of science argue not only that technology is an essential condition of advanced, industrial civilization but also that the rate of technological change has developed its own momentum in recent centuries. Innovations now seem to appear at a rate that increases geometrically, without respect to geographical limits or political systems. The Roman Empire that engulfed and succeeded that of the Greeks was somewhat similar in this respect. The Romans, however, were great technologists in the sense of organizing and building; they established an urban civilization that enjoyed the first long peaceful period in human history. The great change in engineering that occurred in the Roman period came as a shift from building tombs, temples, and fortifications to the construction of enormous systems of public works. Using water-resistant cement and the principle of the arch. Roman engineers were also responsible for introducing the water mill and for the subsequent design of undershot and overshot water wheels, which were used to grind grain, saw wood, and cut marble. In the military sphere, the Romans advanced technology by improving weapons. As agricultural productivity increased and medical science developed, Western society came to have a strong belief in the desirability of technological change despite its less pleasant aspects. Pride and a large measure of awe resulted from such engineering achievements as the laying of the first Atlantic telegraph cable, the building of the Suez and Panama canals, and the construction of the Eiffel Tower, the Brooklyn Bridge. The telegraph and railroads connected most of the major cities with one another. In the late 19th century, the American inventor Thomas Edisons light bulb began to replace candles and lamps, and within 30 years every industrial nation was generating electric power for lighting and other systems. World War I and the Great Depression forced a sobering reassessment of this rapid technological explosion. The development of submarines, machine guns, battleships, and chemical warfare made increasingly clear the destructive side of technological change. In addition, worldwide mass unemployment and the disasters met by capitalistic institutions. Then, with World War II, came the development of the weapon that has since become a general threat to life on earth: the atomic bomb. Another technological outgrowth of World War II-the development of computers and transistors and the accompanying trend toward miniaturization. Innovations in transportation during the middle Ages revolutionized the spread of technologies and ideas across wide areas. These innovations tend to transform traditional cultural systems, frequently with unexpected social consequences. Thus technology can be conceived as both a creative and a destructive process. Md. Atiqur Rahman Nowadays, our lives are completely directed and influenced by technology which has changed people ´s lifestyles. We can see it everyday in the streets where it ´s almost impossible to find someone without using technology. The truth is that we need technology for everything because we are used to living with the advantages that technology offers and for example, it ´s not easy to spend a day without television, computer, vehicle etc. With new discoveries of Technology, difficult tasks are made simple and easy to perform. Technology is a huge contributor to the well being of human kind. Just try to imagine how hard it would be to make it through the day without the simplest of technologies. We have gotten so used to the luxuries that technology provides that many wouldnt know how to adapt to the traditional and simpler methods. Technology has surely proven itself to be very beneficial. Technology took a huge part in changing society from the simple household to warfare. Lets imagine, if one day the power goes off the whole city will be stopped because they are totally paralyzed without using machines and computers which are parts of technology. For our daily life we are so used to technology that if there is no heating system or air conditioning systems either we are going to freeze to death or die in hot. Also now we are so depended on technology that without technology students will stay illiterate for ever because without computers, fax machines or printing machines our school and colleges are like human without any body parts. Technology has definitely changed the lifestyle and common purpose of many humans. Technology has a lots of goods sides but also its have lots of bad side. So I found technology basically harmful and also its make people life lazier. Technology can change our sense of common purpose. For millions of years, mankind has been using to do everything for themselves. For a long time peoples main concern were survival. To survive means to go out into the woods or forests and shoot animals for the food which the family needed to eat for the day. People of modern society never think about hunting for food or clothes. The new standard for survival means making money to go to a mall or supermarket and getting everything a family needs. A family can get food and clothing at these places without ever going into a forest or a lake. This thought is even so frighteningThe technology- resistance movement begins by pointing out that we are cobbling together virtual communities while our real cities crumble, at least partly because our sense of common purpose has frayed. Today, only about 5 percent of American households are on-line, but what happens, the critics wonder, when half the country is wired? Will we escape the unpleasant complications of the world outside our locked doors by opting for communities in cyberspace, where we can enjoy the company of people who share our interests and our views? Where the streets never need to be cleaned and you d ont have to keep an eye on your neighbours house? What happens if the sirens outside become too distracting? Will we simply buy insulated drapes? Humans are getting lazy. Almost everything must be done for them in advance. However, sometimes this change in lifestyle is forced upon humans.At last,I think that this big progress has made our life better and more carious and comfortable but the world isnt better. In the environment there is a lot of pollutions, the crime rate is gone high and the only one thing what people care about is money! People are not eager to do their work by using their energy therefore now a days people are suffering of many diseases. One of the main issue that i consider is a cause of technology is teenagers are getting spoiled because of computers. So as we can see technology is harmful to our health, teenagers, environment and in a word its harmful to this generation. So beside of seeing only the positive sides of technology we should also think of the negative sides and try to think of a better life without using technology. DETERMINISM VS HUMANISM Efficiency and Humanism Together, define the terms, efficiency and humanism, in your own words, and explain how they oppose each other in a paragraph. Efficiency, ratio of the amount of power produced by a machine to the amount of power put into it. But, in philosophy, is skillfulness in avoiding wasted time and effort. Humanism, in philosophy, attitude that emphasizes the dignity and worth of the individual. A basic premise of humanism is that people are rational beings who possess within themselves the capacity for truth and goodness. The term humanism is most often used to describe a literary and cultural movement that spread through western Europe in the 14th and 15th centuries. Technique Technique is the skill or command used to accomplish a specific activity or task. In simple words we can say that special ability to do the task in many ways or in efficient way. Technique is the unstoppable force because technology giving the path to the technique and technology is directly proportional to technique. If the technique increased the technology automatically inflates .We can see the inflation of technique from the early ages they used the technique to solve the different purposes and different works. Till now we see the increase in the technique and with high percentage. In today modern world if someone improving his skill and ability they taking the support of technology because without technology they cannot be finalized there technique. So in last we can say that to make life easier and to do the work new and new inventions takes place. Pre-industrial Society Pre-industrial was a period of gradual change in the way people lived and worked as well as a time when continuity of traditional values and beliefs persisted. Many new technologies were been developed and put into practice due to new demands. This began to revolutionize traditional forms of industry, transport and government. Different classes in society were given a fresh incentive to find new ways of practice which resulted in the birth of capitalism demanding innovation. However much of this change was simply an unconstrained continuance much like a chain reaction, one thing leading to another, therefore not completely replacing established society. The reorganization of pre-industrial Britain was brought about by the combination of many different social, economical, climatic and technological facets. these were the fast evolution of industry and machinery, the advancement of transport, population growth and also importantly the fortunes of agriculture, which in essence acted as a catalyst to the changed. Industrial Society It is defined as the society which refers to have a modern structure. Its basically called the modern society. Every coin has its two sides that are why the industrial society has merits and demerits. First talk about the merits industrial society plays a Vitol role in converting the life of the humans into more technological way. It usually means more jobs, wages going up; more need to have better education. It brings to most a higher standard of living. It makes the life of the people more easy and comfortable. The heavy work or jobs which are earlier did by hands now all the stuff is occupied by the machines. A machine makes the work easier and it takes less time to that work. Businesses become quite easier from early days. All the work and deals are done by sitting in one place through internets, phones, laptops etc. The demerits of the industrial society are through industrialization the poor and the people who are below the poverty line are suffered a lot. Many individuals benefited from the new technological advances, job opportunities, and products. With those wages they could provide for themselves enough to adequately meet their needs for survival. The poor were able to enter the workforce and receive wages. Industrialization helped to reduce poverty which eased the stress on governments. Living conditions for the poor became a pressing matter. Also it puts the really bad effect on environment due to use of much machinery and the excessive use of fossil fuels creates lots of problems like pollution and global warming. In conclusion, it is evident that industrialization had both its ups and downs in society. Technological Society Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons. Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including todays global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms. MAJOR PROBLEMS AND THEIR RELATION TO PAST TECHNOLOGIES Overpopulation Together, show that you know how technology freed us from some things on one hand but created new problems on the other. Overpopulation, growth of population to such a size that space, food, water, or other resources available to support it are insufficient. The rapid and dramatic rise in world population that has occurred over the last few hundred years. The worlds population increased from 1.65 billion in 1900 to 3.02 billion in 1960. The United Nations estimated that the population reached 6 billion in late 1999. Thus, the size of the population nearly quadrupled in the span of 100 years, a historically unprecedented rate of increase. Most of this growth is now taking place in the worlds developing countries, where rates of natural increase are much higher than they are in industrialized countries. Concern that this might lead to overpopulation has led some countries to adopt population control policies. Pollution Together, show that you know how technology freed us from some things on one hand but created new problems on the other. Pollution,  contamination  of  ESarths environment with materials that interfere with human health, the quality of life, or the natural functioning of ecosystems (living organisms and their physical surroundings). Although some environmental pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities. Pollution  exists  in  many forms and affects many different aspects of Earths environment. Point-source pollution comes from specific, localized, and identifiable sources, such as sewage pipelines or industrial smokestacks. Nonpoint-source pollution comes from dispersed or uncontained sources, such as contaminated water runoff from urban areas or automobile emissions. The  effects  of  these  pollutants may be immediate or delayed. Primary effects of pollution occur immediately after contamination occurs, such as the death of marine plants and wildlife after an oil spill at sea. Secondary effects may be delayed or may persist in the environment into the future, perhaps going unnoticed for many years. DDT, a nondegradable compound, seldom poisons birds immediately, but gradually accumulates in their bodies. Birds with high concentrations of this pesticide lay thin-shelled eggs that fail to hatch or produce deformed offspring. These secondary effects, publicized by Rachel Carson in her 1962 book, Silent Spring, threatened the survival of species such as the bald eagle and peregrine falcon, and aroused public concern over the hidden effects of nondegradable chemical compounds. As  humans  developed  new technologies, the magnitude and severity of pollution increased. Many historians speculate that the extensive use of lead plumbing for drinking water in Rome caused chronic lead poisoning in those who could afford such plumbing. The mining and smelting of ores that accompanied the transition from the Stone Age to the Metal Age resulted in piles of mining wastes that spread potentially toxic elements such as mercury, copper, lead, and nickel throughout the environment. Evidence  of  pollution during the early Industrial Revolution is widespread. Samples of hair from historical figures such as Newton and Napoleon show the presence of toxic elements such as antimony and mercury. By the 1800s, certain trades were associated with characteristic occupational diseases: Chimney sweeps contracted cancer of the scrotum (the external sac of skin enclosing the testes, or reproductive glands) from hydrocarbons in chimney soot; hatters became disoriented, or mad, from nerve-destroying mercury salts used to treat felt fabric; and bootblacks suffered liver damage from boot polish solvents. By  the  21st  century,  pollution had evolved from a mainly localized problem to one of global consequences in which pollutants not only persisted in the environment, but changed atmospheric and climatic conditions. The Minamata Bay disaster was the first major indication that humans would need to pay more attention to their waste products and waste disposal practices, in particular, hazardous waste disposal. In the years that followed, many more instances of neglect or carelessness resulted in dangerous levels of contamination. In 1976 an explosion at a chemical factory in Seveso, Italy, released clouds of toxic dioxin into the area, exposing hundreds of residents and killing thousands of animals that ate exposed food. In 1978 it was discovered that the Love Canal housing development in New York State was built on a former chemical waste dump. The development was declared uninhabitable. The worlds worst industrial accident occurred in Bhopal, India, in 1984. A deadly gas le aked from an American chemical plant, killing more than 3,800 people and injuring more than 200,000. The  1986  Chernobyl  nuclear reactor accident demonstrated the dangerous contamination effects of large, uncontained disasters. In an unprecedented action, pollution was used as a military tactic in 1991 during the conflict in the Persian Gulf. The Iraqi military intentionally released as much as 1 billion liters (336 million gallons) of crude oil into the Persian Gulf and set fire to more than 700 oil wells, sending thick, black smoke into the atmosphere over the Middle East. Global Warming Together, show that you know how technology freed us from some things on one hand but created new problems on the other. Global Warming or Climate Change,  measurable  increases in the  average temperature of Earths atmosphere, oceans, and landmasses. Scientists believe Earth is currently facing a period of rapid warming brought on by rising levels of heat-trapping gases, known as greenhouse gases, in the atmosphere. Greenhouse  gases  retain the radiant energy (heat) provided to Earth by the Sun in a process known as the greenhouse effect. Greenhouse gases occur naturally, and without them the planet would be too cold to sustain life as we know it. Since the beginning of the Industrial Revolution in the mid-1700s, however, human activities have added more and more of these gases into the atmosphere. For example, levels of carbon dioxide, a powerful greenhouse gas, have risen by 35 percent since 1750, largely from the burning of fossil fuels such as coal, oil, and natural gas. With more greenhouse gases in the mix, the atmosphere acts like a thickening blanket and traps more heat. Economic Collapse If we talked about the todays problem the most ongoing problem is the economy collapse. Normal people feels less percent problem from pollution, global warming. Its effects but not as much as due to the collapse of the economy because it effects every single person in the world directly or indirectly. WAR is the major victim behind the economy collapse because lots and lots of money spend during war time. Same thing is happens with America. Other reasons behind economy collapse are united States have the biggest economy in the world. Due to war reasons and the major industries shifted to Asia we saw there is a great fall in economy. The whole world is affected and it swallows every single person to its effect. Great decline in employment and goods. The people doing lower jobs who are much educated. The major effect we see in United Kingdom because of migration of economy and worldwide economy collapse. PRESENT TECHNOLOGIES AND THE MODERN CORPORATION Together, discuss how the humanist policies and benefits of the modern corporation are the result of technology changing the workplace. Md. Atiqur Rahman Technological Changes of the Past and Present The technology which surrounds almost everyone in the modern society, affects both work and leisure activities. Technology contains information that many would rather it did not have. It influences minds in good and bad ways, and it allows people to share information which they would otherwise not be able to attain. Even if a person does not own a computer or have credit cards, there is information on a computer somewhere about everyone. The technology which is just now beginning to be manipulated and harnessed is affecting the minds of small children and adolescents in ways that could be harmful. It is affecting our immediate future. It also gives another form of communication and exchange of information which was not available before, information that is both good and bad. Technology is one of the principal driving forces of the future; it is transforming our lives and shaping our future at rates unprecedented in history, with profound implications which we cant even begin to see or understand. Many different elements affect how satisfied we are with our lives. The impact of technology on these elements can change how safe, healthy and happy people feel. Simranjit singh gill According to me the economy defines as the system of the country controlled and managed by the indivisible or by the government or by together in the areas like labour, capital, development. Earlier years there was only one system called physical system where the country is controlled by a person called king. Because he had the power so he controlled the workers according to his work. There was no time limitation, on minimum wage fixed, no safety of the workers. People were less educated and they did not about the work and laws. They did their work like a machines and hear the instructions behindly and did what they gave or what they want. But due to advancement in the in the technology and in the education system people become much aware from past period. They formed the legislation (certain rules and regulations )called workplace legislation. People are much aware about their rights and duties. All this factors led to changed the physical economy into the knowledge economy. There are different types of economies but i am going to explain only two economies 1. Mixed economy 2. Command economy MIXED economy means in which government and the private people controls and managed the economy system. Example Canada , United states, Australia. COMMAND economy means in which all the system of economy controlled and managed by the government. Earlier this system is in these countries China, India and other but due to the time they realised that if we bring the mixed economy it will be more helpful in development so they changed there economy. Jaspreet Singh Ahluwalia We have seen that until now there have been always an end of a generation. If we Compare this to physical economy it has to end one day because the system never has an end with the life. It have to changed one day. Physical economy means there are no limits of work, they can be as the wages paid or the time worked. This is the physical economy people suffered with in olden time. Now days this is not so, we have mixed economy, legislation, command economy and capitalism. ETHICS OR TECHNOLOGICAL DETERMINISM IN POLITICS Ethics and Professionalism: Together, discuss ethics and professionalism, showing you know how both are commonly understood, such as the six stages of ethics and the two levels of professionalism. Ethics,  as  a  branch  of philosophy, is considered a normative science, because it is concerned with norms of human conduct, as distinguished from the formal sciences, such as mathematics and logic, and the empirical sciences, such as chemistry and physics. The empirical social sciences, however, including psychology, impinge to some extent on the concerns of ethics in that they study social behavior. For example, the social sciences frequently attempt to determine the relation of particular ethical principles to social behavior and to investigate the cultural conditions that contribute to the formation of such principles. Economic Imperialism and Globalization Together, show how technology allows economic imperialism, globalization and propaganda. Globalization,  comprehensive  term  for the emergence of a global society in which economic, political, environmental, and cultural events in one part of the world quickly come to have significance for people in other parts of the world. Globalization is the result of advances in communication, transportation, and information technologies. It describes the growing economic, political, technological, and cultural linkages that connect individuals, communities, businesses, and governments around the world. Globalization also involves the growth of multinational corporations (businesses that have operations or investments in many countries) and transnational corporations (businesses that see themselves functioning in a global marketplace). The international institutions that oversee world trade and finance play an increasingly important role in this era of globalization. CULTURAL IMPERIALISM AND TECHNOLOGY Together, discuss what role does technology play in cultural imperialism? Will the Internet play the same role as the phonograph, radio, movies, TV, or will it have a different effect? Cultural imperialism is the practice of promoting, distinguishing, separating, or artificially injecting the culture of one society into another. So this leads to influence of colonies, colony is generally distinguished from overseas possession. So technology is relate with the culture because to travel everything needs a path that path is made by technology. Technology plays a Vitol role in inflation of the culture imperialism. Sets the tone for the relentless critical scrutiny of the rest of the work, with the carefully assembling a system of arguments which ultimately cast a shadow of doubt on the legitimacy of defining aspects of U.S. and Western foreign interventions as cultural imperialism. American culture is rich, complex, and unique. It emerged from the short and rapid European conquest of an enormous landmass sparsely settled by diverse indigenous peoples. Although European cultural patterns predominated, especially in language, the arts, and political institutions, peoples from Africa, Asia, and North America also contributed to American culture. All of these groups influenced popular tastes in music, dress, entertainment, and cuisine. As a result, American culture possesses an unusual mixture of patterns and forms forged from among its diverse peoples. Jaspreet Technology has been a dialectical and cumulative process at the center of human experience. It is perhaps best understood in a historical context that traces the evolution of early humans from a period of very simple tools to the complex, large-scale networks that influence most of contemporary human life. The earliest known human artefacts are roughly flaked stones used for chopping and scraping, found primarily in eastern Africa. The next big step in the history of technology was the control of fire. By striking flint against pyrites to produce sparks, people could kindle fires at will, thereby freeing themselves from the necessity of perpetuating fires obtained from natural sources. Besides the obvious benefits of light and heat, fire was also used to bake clay pots, producing heat-resistant vessels that were then used for cooking grains and for brewing and fermenting. Innovations in transportation during the middle Ages revolutionized the spread of technologies and ideas across w ide areas. Such devices as the horseshoe, the whiffletree (for harnessing animals to wagons effectively), and the spring carriage speeded the transfer of people and goods. Twentieth-century technology spread from Europe and the U.S. to other major nations such as Japan and the Soviet Union. It has not, however, pervaded all the countries of the world, by any means. Some so-called developing nations have never experienced the factory system and other institutions of industrialization. The leaders of such countries tend to feel that the acquisition of modern weapons and new technology will provide them with power and prestige. No one, however, can predict the religious, social, and cultural consequences of the transfer of technologies to these countries. Technology has always been a major means for creating new physical and human environments. It is possible to ask today whether technology will also destroy the global civilization that human beings have created.
