Criminology Paper

To discuss further, the theory of Sampson and L pub supposes that the individual characteristics of a person are not the sole reason for his early delinquency and deviant behavior later in his life. There are social circumstances that may modify the behavior Of other persons while others proceeds with offending. There are three main components proposed in the age-graded life-course theory of Sampson and Lab. First, the delinquency in childhood and adolescence can be explained by their informal relation with their family as well as the environment they have at school.These informal relations they build within their family and at school as well as the social controls coming from these two [family and school] intervene with the micro- level structural context of the children (Sampson & Lab, 1992). Second, in different realms of life, the antisocial behavior from childhood through adulthood continues. Lastly, the informal social attachments that individuals develop to their family and em ployment during adulthood explicate modifications in criminality over their life in spite Of their early childhood tendencies (Sampson & Lab, 1992).The most crucial findings of Sampson and Lab is that the social attachments that individuals develop during adulthood increase some people's social capital, thus leading them to discontinue from most types of aberrant behavior. The theory further discussed how deviant behavior of individuals mitigate as they build social bonds to their spouse or coworkers. People's attachment to their spouse or coworkers increases their self-control that leads to their distance from committing offenses.In the article of Sampson and Lab, they also discuss what trajectories, transitions, and turning points are. A trajectory, as explained in the article, is â€Å"a pathway or line of development over the life span such as workable, marriage, parenthood, self-esteem, and criminal behavior†Ã¢â‚¬Ëœ (Sampson & Lab, 1992, p. 66). In other words, trajector ies are the â€Å"long-term patterns and sequences of behavior† (Sampson & Lab, 1992, p. 66).Transitions, on the other hand, are the specific events in the life of a person. Good examples of transitions are first marriage or first job (Sampson & Lab, 1992). These transitions are implanted in trajectories. Transitions are the changes that are more or less sudden. The close causal connection of trajectories and transitions may create what is called a turning point. A turning point refers to a â€Å"change in the life course† (Sampson & Lab, 1992, p. 66).It involves a certain experience, event, or awareness that leads to the change in the pathway or trajectory of a person over the long-term. According to Sampson and Lab, school, work, marriage, the military, and parenthood are examples of social institutions and triggering life experiences that may change trajectories (1992). The concepts of trajectory, transition and turning points re important in the study of crime beca use they help in understanding the dynamics of life course.From the theories presented by Sampson and Lab, as well as by Cottonseeds and Hirsch, life course is a path, and the understanding of trajectories and turning points help us to give meaning to the different factors that intervene and disturb the path of a person's life course that may lead him to developing deviant or criminal behaviors. Looking at the trajectories of a person, one can ascertain the different relationships that the person has developed throughout time, thus causing IM to becoming what he is in the present time.Trajectories will help us determine the environment that a person has been into, thus leading him to develop characteristics and personalities he has presently. Transitions, on the other hand, help determine whether or not the timing between one event and the happening of another event is enough for a person to adjust This adjustment is important because lack of this may lead a person to develop devian t behaviors. Turning points, or changes in life trajectories, are very crucial in the study of crime because these are often what cause children, or managers, or even adults to exhibit or develop aberrant behaviors.These turning points, such as divorce of parents, retirement, or death, if will not match the behavior of a person may lead to delinquent behaviors. While Sampson and Lab speak of individual's characteristics, social circumstances, as well as social bonds in understanding the criminality of a person, Cottonseeds and Hirsch, in their â€Å"general theory of crime†, propose that the imprudence and criminality of a person can be anticipated merely by looking at the lack of self-control of a person (Sampson & Lab, 1992).They et aside the possibility of the other life and social factors that may intercept in the development of deviant behavior of a person. Nonetheless, Cottonseeds and Hirsch admit that although the personality of a person, for example his lack of self-c ontrol, does not change through time, the connection between self-control and crime is susceptible to change. The concept of life-course perspective of Cottonseeds and Hirsch is inversely linked to the level of self-control of a person.According to them, a person's self-control is what shapes his agency in a manner that he tends to choose to e part of an environment that counterparts his level of self-control. The life course perspective of Sampson and L pub has been recognized by Cacao and Kennedy in explaining social control theory in general. Cacao and Kennedy agree that life course perspective is different from the other perspectives about social control and criminality because it acknowledges how different events or factors in the life course of people affect their progress at different times.By reconciling two contradicting findings in the field of crime research, one finding proposes that adult criminality is strongly impacted by patterns of childhood behavior while the other finding puts forward that changes in the life of people impact their tendency of criminality, Sampson and Lab are able to provide an explanation as to whether or not the propensity to commit an offense changes or remains the same over the life course of people (Cacao & Kennedy, 2011).Cacao and Kennedy further say that the principles laid in the life course perspective are important in understanding the different informal social control present or become present in the life course of an offender that lead to the modification of a arson's criminal involvement (2011). Additionally, the life course approach is a useful tool in ascertaining how changes in crime pattern of people across their life course are being affected with the opportunities and circumstances that they face as they move forward in life.In general, the life course perspective theory' is related to the social control theory in general with respect to the person's bond or attachment to society. Social control theory pos tulates that delinquent acts are often the result of people having a weak or broken bond to their society. This means that when people are less attached to others, they are more prone to deviating from social norms and standards. Since they no important relationships with other people, they really have nothing to lose, therefore, it becomes very easy for them to commit a crime.The life course perspective of Sampson and Lab basically offers the same path of explaining how informal social relations can affect a person's commitment to his society. They say that the attachment or bond that a person develop throughout life with his spouse or coworkers makes a person more committed to his society. He loses his motivation to deviate or to commit an offense because Of the social bond he has developed mainly due to her concern for his spouse or coworkers.

Concocting a Divisive Theory

Concocting a Divisive TheoryThe phenomenal recovery of an mtDNA section from the arm of the Feldhofer Cave Neandertal was greeted with the enthusiasm and yes, even with the ballyhoo it deserved. 1 It was a truly important discovery, and from a research lab that every bit late as a twelvemonth before had predicted it could n't be done. The protagonists of the theory that Neandertal mans are a different species were beyond exuberance ( few others were quoted on the issue ) . And so, in a crescendo of excitement, Stringer and McKie2 delivered their putsch de gra?ce in a New York Times op-ed discoursing the significance of the Neandertal mtDNA findings: The deductions for the thought of race are profound. If modern humanity is made up of people who are all recent posterities of a few African innovators, it is every bitclear that Homosexual sapiens must be a startlingly homogeneous species. We merely hold non had clip to diverge genetically in any meaningful mode. However, some scientists and those with narrow political dockets have put frontward statements to prolong the thought that races exist with cardinal biological differences. Alternatively of concocting dissentious theories, we would be better served to acknowledge the importance of recent informations that will assist us happen the properties that separated Homo sapiens from other early worlds like the Neanderthals.Is this more opera or is it all over?Have the antediluvian DNA surveies brought us a existent discovery and ended the Neandertal contention so exhaustively that the lone holdouts should halt concocting their dissentious theories because they can merely differ if they have a political docket about race? Tattersall3 believes it is all over. He interprets the mtDNA consequences as demoing that the Neandertals were a distinguishable species for 600,000 old ages. For this reading, one must presume that the history of the Neandertal mtDNA line of descent section is a population history, that invariably roll uping mutants are the exclusive cause of mtDNA development, and that the mutant rate of mtDNA is known with sufficient truth to day of the month the putative split. Belief in the Eve theory of modern human beginnings is the most of import requirement for these premises because it ties mtDNA history to population history through the account that low mtDNA diverseness inworlds comes from a recent population- size constriction ( in this instance, a new species ) . It is no surprise that Eve theoreticians reacted to the intelligence with joy. It is non that I want to rain on anybody ‘s parade, but there are some shrewish inside informations. Let ‘s expression at what was really done. Krings and coworkers1 reported that the 379 base-pair section of mtDNA found in the Feldhofer specimen has 27 differences from the mention human sequence and, significantly, that 25 of these differences were at places that varied in at least one of their comparative human samples of 2,051 persons. When the Neandertal sequence was compared with 994 modern-day human line of descents of known geographic beginning, the figure of differences was more than three times greater than the average figure of differences between the worlds.But possibly the most surprising determination was that several of the worlds were found to differ from each other more than the Neanderthal differs from some worlds.Lineages in the human sample have between 1 and 24 pairwise differences reflecting mutants, while the Neandertal differed from these worlds by between 22 and 36 mutants. Taking the difference in ages into history, every bit good as the fact that any peculiar mtDNA line from that clip had merely a little opportunity of prevailing until today, this form of fluctuation is to be expected, given that an ancient Neanderthal man is being compared with modern-day worlds. In such a comparing, the pairwise differences must ever be greater than they would be for the ascendants of the modern-day worlds in the analysis who were populating at the same clip as the Neandertal. This is because the modern-day homo mtDNA lines have had a longer clip to mutate. Whether the magnitude of fluctuation is to be expected is a different inquiry. The reply could depend on the mtDNA mutant rate. Here, excessively, there have been surprising finds. Until late, the rate of alteration for human mtDNA was determined phylogenetically. Dates for mtDNA coalescency were estimated by comparing the maximal pairwise difference among worlds to the figure of differences dividing human and chimpanzee sequences. Dates for human and chimpanzee divergency were so used to gauge the rate of alteration. The Neanderthal divergency day of the month estimated by Krings coworkers assumes a mutant rate at about the center of the But possibly the most surprising determination was that several of the worlds were found to differ from each othermore than the Neanderthal differs from some worlds. scope for phyletic findings: 0.01 to 0.2 permutation sites each million old ages. But, in fact, even the fastest of these rates may be wrong. When Czar Nicholas II and his household were exhumedin 1991, their designations were based on fiting their mtDNA with that of other descendants of the Czar ‘s female parent. These analyses out of the blue revealed immensely more mutational alterations than the phyletic rates predicted.4 Subsequent computations of mutant rates between coevalss proved to be dramatically higher than had been assumed from the longer-range phyletic considerations. In two different surveies, 100s of base brace from the mtDNA control part ( more than in the Neandertal analysis ) were sequenced and intergenerational mutant rates of 1.2–4.0 permutations per myr were derived.5,6 The Eve theory postulates that a recent population-size constriction took topographic point at the clip of mtDNA coalescency in worlds. But if mtDNA mutant rates are so every bit high as the intergenerational analyses indicate, the ‘‘Eve † of these surveies could good hold been a Biblical figure because she would hold lived merely about 6,500 old ages ago. Of class, a population-size constriction this recent is extremely improbable because ‘‘it remains puzzling how the known distribution of human populations and cistrons could hold arisen in the past few thousand old ages. †6 A much more likely account for today ‘s mitochondrial diverseness is that there was no recent population constriction, but that the mtDNA has limited fl uctuation because of choice. It is known that the development of human mtDNA departs from neutrality. Choice can explicate this and the limited fluctuation in human mtDNA by, for illustration, long-run background choice against somewhat hurtful mutants, 7 or by episodes of directional choice, or, possibly a selective sweep.8 Selection is an of import component in mtDNA development because mtDNA does non recombine. Therefore, choice against any part reduces variableness in the full genome. 9 Even on the same chromosome, nonrecombining parts have much lower fluctuation than do recombining parts. One dissentious theory is that choice has reduced mtDNA fluctuation in worlds since the Neandertal lived. A concluding item is related to the claim of Krings and coworkers1 that the Neandertal is every bit related to all life people. This contributes to the perceptual experience that he was genetically isolated from them. But these writers merely presented their comparings for wide continental groups ( Africans, Europeans, and so on ) . A more appropriateanalysis is populational. A comparing of the Feldhofer Neandertal with gene-bank informations for 14 world-wide populations resulted in an mean pairwise difference of 27.3, the same average difference as in the survey by Krings and coworkers.1 But in this instance, pairwise differences for specific populations could be straight examined. These ranged from 21.3 to 33.2: the smallest average difference was between the Neandertal and a sample from Finland. One can conceive of the dissentious theory that might be concocted from these findings. There are others, largely geneticists, who besides have been busy concocting dissentious theories about modern human lineage agree on one point: The Eve theory is wrong.9,11 The job they all reference is that a population constriction terrible plenty to reset mtDNA fluctuation to zero would reset atomic fluctuation as good. Mitochondrial cistrons should retrieve their fluctuation and return to equilibrium much more rapidly because of their higher mutant rate and smaller effectual population size. But it is merely the antonym. MtDNA is out of equilibrium and has small fluctuation, whereas all impersonal atomic cistron systems studied so far are in equilibrium and have more variation.7,8,12 This entirely regulations out a terrible population-size constriction. One late supported theory is that modern worlds are non a new species but descend from a little hereditary group that lived in Africa for at least a million years.13 Others are based on analyses of the beta-globin genes14 and the Y chromosome,15 each of which reveals grounds for important genetic exchanges both out of Africa and into Africa much earlier than the period of mtDNA coalescency, even when the phyletic mutant rate estimations are used. A population-size constriction would hold erased this older fluctuation. But if the Eve theory is incorrect, there is no ground to restrict accounts of the Neandertal mtDNA to past species divergency ; nil to confute the contention that the Neandertal reflects a greater magnitude of mtDNA fluctuation in the yesteryear than in the present ; and nil to take away from the impression that mtDNA can differ dramatically between sections of the same species. Human fluctuation with and without Neandertals is similar to the difference between Pan troglodytes races. In that comparing, Pan troglodytes verus has much more mtDNA fluctuation than does Pan troglodytes schweinfurthii.12So what does the antediluvian DNA mean with regard to the topographic point of Neandertal mans in human development? The deductions are inconclusive. It seems that dodo anatomy still provides cardinal informations about human development. Many Neanderthal characteristics persist in much later post-Neandertal Europeans.16 Furthermore, it is normal to happen mixtures of assorted Neandertal characteristics in Europeanstoday. One recent analysis of Neandertal and early Upper Paleolithic European nonmetric traits indicates that their fluctuation requires Neanderthal alloy of at least 25 % .17 Further survey of these informations estimated an about 6 % Neandertal familial input in modern European cistron pools, a determination that is in line with the pairwise difference analysis ( but does non necessitate ancient mtDNA ) . And what does this mean for the Multiregional theory of development? Here, the reply is clearly nil because multiregionalism means development in more than one part, but non needfully in every region.18 It could be a valid account for human development even if every individualSo what does it intend? The antediluvian DNA findings are compatible with both phyletic readings of Neandertal mans: separate species or human race.Neanderthal became nonextant without issue. Human populations do non prevail infinitely or continuously through clip. All of them either go nonextant without issue or merge with other populations. So what does it intend? The antediluvian DNA findings are compatible with both phyletic readings of Neandertal mans: separate species or human race. But there are other, independent grounds for rejecting the impression that Neandertal mans are a different species. Tattersall and I have discussed some of these in old arguments in Evolutionary Anthropology. The fact remains t hat ‘‘the familial fluctuation between the modern and Neanderthal sequences is within the scope of other species of Primatess. †19 If Neandertal mans are non a separate species and the Feldhofer Neandertal informations prove valid, they give us two of import pieces of information. First, they indicate that if a selective expanse in human mtDNA led to its presently low degree of fluctuation, it was more recent than at least some of the European Neandertals. This could supply independent support for generational clock rates, but extra antediluvian Deoxyribonucleic acid analysis is necessary to analyze this possibility. Second, they remind us that computation of mean effectual population size in the yesteryear from coalescency theory has no relation to the existent figure of engendering females populating then.9,13 Although the sample made up of the Neandertal plus life worlds has a much larger effectual mitochondrial population size than life worlds do, it is unreasonable to reason that there were more people alive during Neandertal times than there are today. Ironically, even as the new informations raise the Neandertalargument to a higher and more interesting rational degree and represent how familial and palaeontological informations can be wed, the political degree of argument sinks to a new low.Mentions1 Krings M, Stone A, Schmitz RW, Krainitzid H, Stoneking M, Pa?a?bo S ( 1997 ) Neandertal DNA sequences and the beginning of modern worlds.

Factors Affecting Development

Skinner views are that children learn language through imitation, and they copy from how their parents talk. He thought that children learn mostly through positive and negative reinforcement. When an adult feels as if the child is learning how to say a word from their babble such as ‘baby’ they will repeat it continuously so that in the end result the child will learn how to say the word. (6-12 months) Bowlby thought that a mother and a new born would need to bond with close contact for a good long term development.His views were that babies wanted to be close with the main parent/carer at all times to feel safe and when it was achieved, the babies constant need for attention would stop. When the baby is put in a new environment or separated from their main carer they will feel unsafe and start their crying for attention so they can be close with their carer again. This theory is called ‘attachment’. (0-3 months) Darwin believed that children were born with basic emotions; babies learn appropriate emotional responses from watching other people around them and observing how they react to things.They check their parent’s facial expressions or body language before responding positively or negatively to a situation (Squire 2007:105). (0-3 months) Schaffer views were that there were three stages of development in infancy, in stage 1 it showed that the baby was more drawn to people than inanimate objects and would smile more around a human than if left with inanimate objects like toys. In stage 2, the baby will be around 3 months and will be able to recognize the difference between their parent/carer and other strangers, babies may not mind being held at this stage because they’re too young to see the strangers as a threat.In stage 3, around 6 months a baby will form a stronger bond with their main caregiver and will try to seek attention. The child may become distressed when their carer is out of sight and will also cry around strangers because they may be scared. (0-3 months) Piaget believed that children learnt through first-hand experience and discovering things and exploring rather than just being told or shown. He thought that that the parents/carers should make sure that they are providing resources to help the child develop further.Letting children play freely will benefit the child as long as there are boundaries put in place to make sure it is safe for the child to explore e. g. if the child was playing outside in the garden, they will need to be supervised because they may hurt themselves or eat something they shouldn’t. The gates should also be checked to make sure that the child can’t get out. (1-2 years) Vygotsky believed that the level of development for a particular child was known as ‘the zone of actual development' but he thought that a child was capable of more if encouraged and assisted by their parents.The difference between the two levels was the ‘zone of pr oximal development ‘Adult intervention is necessary if the child is to move on from one level to the next. For example if a child is learning how to stand up without holding onto anything the next step would be for their parents to assist them in taking a few steps with them or providing a walker for the child to learn independently. (2-3 years) Factors affecting developmentSmoking while pregnant will cause the baby to have low birth weight and there will be a higher change of you’re the baby being stillborn. There will also be a higher chance of cot death. Smoking may cause miscarriage or premature birth. Smoking around new-born can affect new-borns even though they are outside the womb because they are inhaling second hand smoke, it can cause severe respiratory diseases and it can delay growth of their lungs.  (0-3 months)Children in the age range of 7-12 mostly socialize with their own gender because they go through the stage when they may dislike the opposite gend er and think there gender is the best. The NIH Study shows that girl’s brains develop before than a boys brain does and that girls reach maturity before boys. (7-12 years) Children living in better conditions are more likely to have a healthy lifestyle which affects their physical development, they will be more likely to be able to go on a lot of holidays, pursue hobbies like music and dance and art.They will be more likely to have the clothes that everybody wants and the school may be in an area where there are better schooling opportunities which will increase the chance of emotional stability. Children living in poverty are unlikely to have poor housing, diet and education. There may be higher crime rates in the area which would influence the children’s social and emotional behaviour. They may also have fewer chances to join clubs or join into hobbies they like or to go on holidays. (3-7 years)

Manufacturing Industry Evaluation - Essay Example As a result, the larger firms keep acquiring other small firms as they continue dominating in the markets, effectively reducing competition in this industry (Lynn, 2002). The Envelope industry is such other industry of the US that has low competition. The larger firms control most of the US markets for this industry. Oligopoly refers to a market condition, where the market has many buyers and very few sellers. In an oligopolistic market, just a few firms, mostly the larger ones, dominate the market (Elmer, 1999). Since there are few sellers in such a market, every firm operating in that market has the chances of knowing the moves and the trends that the other firms are making in order to achieve a competitive advantage in the market. Consequently, the firms operating in an oligopolistic market conditions are most likely going to make their decisions based on those decisions made by other firms. Thus, in an oligopolistic market, the decision made by one firm affects the other firms and vice versa (Case, Fair, and Oster, 2009). The characteristic oligopoly market involves the firms producing and selling their products at the quantities and prices they feel are suitable to grant them the profit margin they require. Thus, oligopolies set the market prices for their products, other than selling their products at the existing market prices (Elmer, 1999). In the US, the Envelopes and the Fluid Milk industries qualify as oligopolies. The Fluid milk industry in the US is an example of an oligopolistic market condition, where the market in the industry is dominated by few firms. The dairy cooperative of the country called the Dairy Farmers of America have effectively established close alliances with the other players in the industry, notably the Dairy Market services, which has on its side collaborated with the US major milk manufacturers (Lynn, 2002).

Strategy, Information Systems (IS) and Knowledge Management Essay

Strategy, Information Systems (IS) and Knowledge Management - Essay Example However, it is crucial to understand why competitive advantage is of significant value. The paramount reason is that it allows a business to hold a superior status in the market. Having a dominant position implies that a business can have cost leadership, where it dictates the prices of products by partnering with suppliers in a monopoly-like manner. This is not sustainable over the long run; subsequently, business must create unique value around their products to draw out the largest market share. Hence there arises two ways of gaining competitive advantage, through cost or through differentiation. Either way, a business should seek this as it allows creation of profits that exceed their competitors. These excess profits in turn, can be used to further market the business by promoting its products and services, and boosting its image. In addition, the business can set aside money for continual assessment of its strategies, which involves research that ensures it is always up-to-date with trends within the industry (Worth, 2009). One of the core competencies that all businesses have or can easily acquire is information. Businesses need to create an environment that allows for dynamic use of information, to maintain high levels of performance, continuous growth and facilitate approaching of beneficial risks. To achieve these results from information effectively, there needs to be a shift in thinking from the traditional perspective to a dynamic one. Organizations need to think about information in three different ways, in order to leverage information systems to gain competitive advantage. These are recognizing the various sources of information within a business, acknowledging the purposefulness of a well-informed business solution and going over the overall IT situation to ensure it supports the business needs as and when they occur (Hurwitz and Kaufman, 2007). Recognizing the various sources of information involves looking at non-traditional sources of inform ation, in the sense of original point. That is, managers should seek information from emails, custom applications and reports as opposed to conventional sources such as content management systems e.g. ERM and customer databases. Of significance with this aspect is that quality of information will be high, and decision-makers can make timely decisions as they will recognize this information and act on it prudently. Managers should not ignore these sources as gaining competitive advantage necessitates leveraging all kinds of relevant information, as this will enable establishment of sustainable strategies (Hurwitz and Kaufman, 2007). Acknowledging purposefulness of a well-informed business solution is reliant on the infrastructure currently adopted by business. This means that a business solution will have a certain modularity and level of flexibility depending on the structures and systems in place. Modularity and flexibility implies that linkages between rigid information systems an d structures, and applications can be adjusted to meet the changing needs of a business as dictated by the environment. An effective business solution should unify the metadata such that for instance; characteristics that describe how to locate, access and utilize data will be maintained. Essentially, all relevant informat

Elements influencing Robustness of the research Essay - 3

Elements influencing Robustness of the research - Essay Example The discussion section also relates the study to back to the literature review and places the study in context. For instance, it has been identified in the literature review that the duration of showering that is considered therapeutic for laboring women is approximately 30 minutes. According to the literature and discussion of the article, prolonged showering to more than 30 minutes may put the women at risk for dehydration and hypotension; thus, enough hydration, drinking of cold water, and securing availability of an adult after showering is recommended. Meanwhile, the hypothesis was identified and supported in the discussion section. The hypothesis that women would benefit from showering within 30 minutes of showering was indeed supported as findings of the study found out that the intervention being tested would not likely to cause hyperthermia or fluid shifts. The strengths, limitations, and generalizability of the study were also discussed. Strengths include careful monitoring of the pilot study, values within the normal range, and safety of the intervention. Limitations include small sample size and failure of the participants to follow the instructions in adjusting water temperature and flow. The researchers stated that even of the study has small sample size and is underpowered, the result of the study among non-pregnant women could also be applied to the general population of pregnant women. All references are accurately cited and referenced in APA format. Olson, Wahab, Thompson & Durrant (2011) presented appropriately the findings that drives Hispanics, Native Americans, and Anglos to complete a suicide using their suicide notes (1491). The report of suicide among these races addressed what is already known about the motivation one has regarding completion of suicide. In the study, authors stated that suicide involves diverse motives

A fountain pen Essay Example | Topics and Well Written Essays - 1250 words

A fountain pen - Essay Example Companies source raw materials required in the production process from various stockholders and international suppliers. Before distribution to various target markets, assembling of the components occurs at specific sites (Anklesaria 211). The design of fountain pens is in various ways and styles. A fountain pen may be custom made or produced in bulk. In designing custom fountain pens, an individual generally decides the elements and style that he wants to be incorporated in the product, thus may include specifications like, color, laminating strips, the engraving of particular patterns on the surface, or inlaying materials like gemstones into surface. A custom pen usually has a different and unique look from the design of other fountain pens produced in bulk. Mass produced pens usually resemble in design and shape but may differ in color. This is because custom pens are generally expensive to produce than the mass-produced pens. A fountain pen incorporates various materials in its production process. The pen’s barrels are made from a series of materials including gold, silver or copper; however, these materials are utilized for custom pens. Consequently, mass produced pens are produced out of inexpensive materials including Lucite also referred as acrylic resin, cellulose acetate among other moldable polymers. Consequently, hand-made fountain pens use stable and solid materials including plywood, leather, antlers, and crushed velvet. These affordable materials utilize simple tools in production. Moreover, the nib is also a vital component of the fountain pen, which is usually made out of stainless steel, gold, or sterling silver as the former is the widely utilized material. On the other hand, the pen fittings and clips are made out of electroplated gold alloys while custom pens may make use of gold (Anklesaria 211). The ink is also an important

As a department head in the hospital, you and your colleagues need to Term Paper

As a department head in the hospital, you and your colleagues need to decide on whether to purchase new equipment - Term Paper Example A decision whether to own or lease a particular piece of hospital equipment would have to take into account many factors. The most obvious is the cost of the equipment. In the given scenario, the cost to buy is $75,000. Needless to say that this is a considerable sum of money to pay outright and therefore there is an alternative consideration at hand whether to lease the equipment for five years. The lease rental is $ 11,000 per year, for five years. Depreciation is one factor that needs to be considered as well as it would reduce the value of the equipment. Another factor would be revenues and number of people using that equipment. In an operating lease, the lessor would bear the cost of reduction in the value of the asset, but in the case of a capital lease, this would be transferred to the lessee. A lease is considered to be a capital lease if (a) the terms of lease contain a bargain price option, (b) the lease term is equal to 75% or more of the estimated useful life of the asset, (c) the present value of the minimum lease payments amount to 90% or more of the fair value of the leased asset, and (d) the lease transfers ownership of the asset to the user at the end of the lease term (Meigs & Meigs, 1993). We are told nothing about (a) or (d) but can calculate (b) and (c). We are told nothing about the discount rate to use here to calculate the present value of the lease rentals. However if we assume a discount rate of 10 percent, the present value of the lease rentals will be as under: This calculated present value is more than 90 percent of the depreciated value of the equipment as at year 5. Ninety percent of the depreciated value of the equipment amounts to $40,500 in year 5. So it is definitely a Capital Lease. In the current circumstances, it would be better to buy the equipment rather than to lease it. This is because the salvage value of the equipment at

Legalization of marijuana. How can it boost the U.S economy Research Paper

Legalization of marijuana. How can it boost the U.S economy - Research Paper Example Legalizing marijuana will increase the government tax revenue. The government loses huge revenue from the illegal trade and use of marijuana. Marijuana is the most consumed and most traded substance of abuse in the US. Whether legal or illegal consumers must always find a way of getting it and traders have to smuggle it in the country through the black market. The implication of illegal trading of marijuana is the huge loss of revenue the government could raise through taxation. Therefore, legalizing marijuana gives the government a chance to regulate it through taxation hence increase of national income. For example, the state of Colorado estimated a revenue increase of about $67 million from marijuana sales the first year after legalization. Increase in national revenue will contribute to economic growth because the additional revenue can be used to carry out development activities of the government.Legalizing marijuana will increase employment because many people can open up busin esses as traders, farmers, distributors, etc. Increase in employment opportunities in the country is a contributing factor to economic growth through income they earn. Increase in citizens’ income results to increase consumption hence increase in economic growth.The U.S. government incurs huge expenses to the tune of $40 billion to enforce drug regulations every year. Most of the inmates causing congestion in the U.S. prisons are victims of drugs that have not been involved in any crime of violence.

Performance Measurement Systems of Organizations Essay

Performance Measurement Systems of Organizations - Essay Example The different types of performance measures are input measures, process measures, output measures, outcome measures and impact measures. The organizations can develop their own customised systems to meet their specific requirements and circumstances or utilize a number of performance management models and tools to develop their framework. The major performance measurement systems in use today are Balanced scorecard, Activity-based Costing and Management, Investors in People Standard, Quality Management, Charter Mark and Performance Prism. The frameworks are explained in the following sections. A Balanced scorecard defines what management means by "performance" and measures whether management is achieving desired results. Kaplan and Norton (1992) noted that it was designed to improve current performance measurement systems by providing alternatives to managing organizational performance exclusively through financial measures. According to them (1996), "the name reflected the balance between short- and long-term objectives, between financial and non-financial measures, between lagging and leading indicators, and between external and internal performance perspectives." According to CIMA (2005) official definition, the Balanced scorecard is "an approach to the provision of information to the management to assist strategic policy formulation and achievement". A Balanced scorecard is used to clarify or update a business's strategy, link strategic objectives to long-term targets and annual budgets, track the key elements of the business strategy, incorporate strategic objectives into resource allocation processes, facilitate organizational change, compare performance of geographically diverse business units and increase companywide understanding of the corporate vision and strategy. Evolution of the concept The concept was originated by Robert Kaplan and David Norton (1992) as a performance measurement framework that added strategic non-financial performance measures to traditional financial metrics to give managers and executives a more 'balanced' view of organizational performance.The developments in the concept are as follows: a. 1st generation- The Balanced scorecard designs feature a small number of performance measures typically spread across four perspectives, namely; financial, customer, internal processes and learning and growth, as proposed by Kaplan & Norton (1996). b. 2nd generation- New Balanced scorecard designs illustrate how the various objectives are related using a diagram called the 'strategic linkage model' or 'strategy map' (Kaplan & Norton, 2004). Using objectives and linkages helps to provide a stronger basis for choosing measures and for justifying these choices to others. c. 3rd generation- The third generation of Balanced scorecard designs were developed in 2000. These are easier to develop, implement and use than any earlier version. Balanced scorecard has become the focus of a wider strategic management process - a framework for strategic management and control rather than just a performance measurement device. Perspectives The Balanced scorecard sets out a framework of four key perspectives (Kaplan and Norton, 1996), as shown in the following figure. Figure 1 - Perspectives of Balanced

Human Resource Management - Research Paper Example ed customer requirements, difference in the cultural values among the people or the workers, an overabundance of stakeholders like customers, investors and so on with varied claims, diverse economic, political as well as legal environments and lastly the assortment of strategies of the competitors (Financial Times, 2007). Cultural Factors Cultural factors are considered to be the slightest substantial factor but for international organizations, they turn out to be one of the most important factors. Culture is perceived to be the features and behavioral structure of the people of a particular society. Cultural factors include religion, customs and approaches, language, values and mind-sets, education, material constituents, social foundations and aesthetics. Culture can also be said to be the complete system of life of the people in a specific society. For organizations to be successful, it is vital that they take into deliberation and adapt to the culture of the country or society. U nderstanding the cultural factors assists in endowing with competitive advantage to some extent to the organizations (Lan & Unhelkar, 2005). For instance, the Indian culture is quite open to new products, ideas and thoughts and accepts change without much hesitance. Thus, the people in India working as employees can adapt to the different working style and ways without much hesitance, whereas the Japanese culture is quite rigid and is not open towards accepting all and every kind of alterations in their society. Thus, organizations branching out in Japan should take it into concern and should be careful to practice their business operations according to the societal ways. Any alteration in the ways of working in the organizations would not be readily accepted by the local employees and... This essay stresses that the growing organizations require complying with the Organization for Economic Cooperation and Development or the OECD. This is considered as the developer of rules in case of industrialized countries. The International Labor Organization, involved with the issue of ‘direct investment’ in the developing nations, can also be considered as another developer of code of conduct for globalizing companies. This article makes a conclusion that organizations need to concentrate and focus on multiple factors while planning their global expansion. The success or the failure of organizations is dependent on the proper treatment and understanding of the above mentioned factors. It is quite important for organizations to take these issues into consideration so as to attain competitive advantages along with global success. Successful global expansion would ensure the sustained existence of such organizations in this fiercely competitive age. It should be kept in mind that the adaption of effective human resource management strategies is the most significant aspects to be considered while expanding globally. It can not only minimize the risks associated with environmental and cultural divergences, but can also reward the organization with better productivity and sustainable growth in the market. With this concern, the human resource management practices should be altered according to the cultur e, preference and trends of the host market.

A clockwork orange Essay Example for Free

A clockwork orange Essay By the end of the novel Alex has changed as if by clockwork, because he cannot stop himself growing up into an adult and he knows that he will become one of the bullied people as the new youth are born, and if he has kids that they will go through the same process as he did, just like clockwork and he cannot stop it from happening: and nor would I be able to stop him. And nor would he be able to stop his own son, brothers. And so it would itty on to like the end of the world. After chapter two, he said I am a clockwork orange, this is because after Lodovicos technique, he had no free will because as he could not even protect himself from fights because whatever the doctors said he would do, in this sense he has become a machine, or a clockwork toy, like childrens toys, as this novel has many references to childrens things, which have been warped, like the milk with drugs in it, and now Alex being a clockwork toy. These attempts to change him failed because he had become a mechanism of the doctors, and change was forced upon him, but the final chapter of the book shows that people change and mature naturally from within, change cannot be forced upon them. The novel Dr Jekyll and Mr Hyde has a completely different structure to that of A Clockwork orange. In Dr Jekyll and Mr Hyde there is the use of multiple narrators, instead of just the one. This tells us, that there was no voice for the people not in the higher class of society with the upper class only important, because all the narrators are all high-class people with well paid jobs, as seen by: Mr Utterson the lawyer this shows that Victorians had a very narrow view of society. This relates to Robert Louis Stevensons background because he was brought up in the upper middle classes of Edinburgh, he was raised as a Calvinist, in which the elect were the ones blessed by God, who turn out rich and the reprobates had a bad life, however Stevenson rebels against this and gives up law to become a writer, and he marries an already divorced woman with three children, he also by the final years of his life travels the world, this is why we only hear from Jekyll/Hyde in the last chapter, because Hyde represents rebellion , as Roberts life was very restricted, like Jekyll before he rebelled, but after he rebelled he was free like Hyde. Stevenson breaks the book apart in this way because at the time he wrote the book, society was disintegrating, as immigrants were coming to London bringing disease, religion was breaking apart because of science, crime was rising, and there was a huge division of classes, and Hyde in the novel is represented as foreign, as he is described as some damned juggernaut, which is a Indian religious statue which is carried through the streets not stopping even if people are crushed underneath it, portraying him a some sort of disease. The language of Jekyll represents that of the other narrators in the novel, because all of them are upper class men so they are expected to talk in a certain manner, as seen: But I have been pedantically exact, as you call it, this is quite a high class way of speech, and Jekyll is narrowed by this way of speech because he is high class. However in the final chapter, the language starts to change because he has to make a final decision about who to stay as, Jekyll, or Hyde, as he start to become scared, as when Jekyll starts to describe his transformation into Hyde the language becomes more fluent, fun, youthful language: Edward Hyde would pass away like a stain of breath upon a mirror However Jekylls speech was respectable, but with boundaries, and was very sharp and did not flow like Hydes. Jekyll enjoys evil in the form of Hyde, because in a way it gives Jekyll an opportunity to experience free life without having to be a lower class. He enjoys the life of Hyde more because it has no boundaries, and he feels free with it. In Jekylls normal life he is bounded by upper class rules so he has no passion, which he really wants. This resembles A Clockwork Orange, as the final chapter of A clockwork Orange, ends unhappily, because Alex has lost all his passion, and beauty, because of his changes in music: I was slooshying more like malenky romantic songs when he was small he was full of life when hearing Beethoven, and he has lost that as he has become older, his fun youth days have gone. This is like Dr Jekyll and Mr Hyde because with Jekyll his class binds him, so he cannot be free and have wild fun, but when he is Hyde he is free and youthful: I was often plunged into a kind of wonder at my vicarious depravity, he is also younger, lighter, happier, and he gets a heady recklessness when Hyde. Stevenson is like Hyde in the sense that, Hyde is a figure of rebellion again the upper class boundaries, and Stevenson did exactly the same as he rebelled against Calvinist beliefs. He could also be seen like Jekyll, bounded because of his class, but Stevenson bounded by his illness, and all the time he wanted to break free, and finally he did, to become an individual, not held back by beliefs, or morals. This novel says that morals and classes cannot bind human nature, people have to become what they become, and there is no stopping that, because as people grow they will change, and rebel against beliefs, which they think, are wrong.

Comparison between hmv and itunes stores

Comparison between hmv and itunes stores Introduction: In the past 10 years the internet or e-technology has altered how the industries operate. More affected by the new technology is the music and video industry later the book industry with eBooks. Traditionally consumers have purchased music, video or a book from a store. If it is a music or a video it is bought on CD / DVD and but with the internet came new ways of getting digital content. Apple has launched ITunes for delivery of digital content directly to the consumer, with no physical presence. HMV is using a mixed strategy of maintain a physical store as well as having a website for selling the digital content but the delivery is through shipment of CD/ DVDs. They both operate under the same model B2C. But they have different ways of delivering the goods / services to customer. HMV HMV is the UK and Irelands leading specialist retailer of Music, DVD/Video, Computer Games and Related Products. The company operates around 200 stores in key shopping locations nationwide, equating to over 1million sq. ft. of trading space, as well as a successful online store at www.hmv.co.uk, operated by HMV Guernsey1. HMV sells content in physical from and operates in physical as well as virtual space. ITunes Store The iTunes Store is a software-based online digital media store operated by Apple Inc. Opening as the iTunes Music Store on April 28, 2003, with over 200,000 items to purchase; it was as of April 2008 the number-one music vendor in the United States. As of January 2009, the store has sold 6 billion songs, accounting for 70% of worldwide online digital music sales and making the service the largest legal music retailer. As of Sep 2009 the sales of ITunes are 8.5 billion songs, 1+ million HD movies and TV episodes, 2 billion apps with a combines revenue of $ 6.7 Billion 2 . ITunes sells digital content and has virtual presence only. SWOT Analysis: HMV Strengths: * Has both online and physical store presence. Customer can access any of the 2 ways to interact with HMV. * Can sell any item MUSIC/ DVD/ GAMES, no need for any arrangement with HMV. * Can deliver physical items like gaming consoles, posters/ cards etc. Weakness: * Cannot sell individual items in music albums or individual episodes in TV shows. * Not available all the time (except online, which requires shipping of product) Opportunity: The opportunity for stores lies in enhancing the customer experience at the stores. Threat: The physical stores are fast losing significance; the rivals like Zavvi, Woolworths have closed most of their physical stores. Becoming obsolete is the threat faced by the stores of HMV. Itunes: Strengths: * Suits the needs of the current generation. * Content is immediately available for consumption. * Available anytime and anywhere. * It is backed by one of the best companies in the tech world, Apple. Weakness: * Can sell only the products like music that it has been agreement with companies and is authorized to sell. * Cannot sell and deliver online physical items like posters/ cards etc. * Cannot sell items that are huge in size in terms of memory. Games DVDs are usually of a size of 4 Giga Bytes or more and are difficult to download online. * Not available in all the countries. Opportunity: The opportunities lie in expanding into other segments of digital content like eBooks. The Ibooks which is a past of iStore is planning to sell eBooks directly to the customer. Threat: The model of ITunes is easily replicable. The threat is from rivals like Amazon and HMV who want to sell digital music to sell directly to customers same way as ITunes does now. SLEPT Analysis Before creating any business strategy or while evaluating an existing strategy it is extremely important to scan the external environment. SLEPT analysis is an investigation of the Social, Legal, Economic, Political, and Technological influences on a business3. Social: The changing demography of the people will have an impact on the business. The social changes can be psychological, demographical etc. The psychological change that is witnessed is the need for making things happen fast. People do not want to wait for placing an order and waiting to receive it by post. Most of the music albums have one or two hot songs and todays consumers are not willing to pay for the entire album. They want to pay only for the songs they like. Legal: Since the advent of new technology the music industry has been losing its revenue. The illegal file sharing has eaten into the revenues of music companies. Music companies have been suing the file sharing sites like Napster and more recently the piratebay. Even the individuals are sued by the industry; Recording Industry Association of America (RIAA) has successfully sued a Minnesota woman for copy right infringement and illegal file sharing4. Legal battles resulted in buying of digital content by the consumers. The legal issues lead to the online stores like ITunes that sell music legally online. Legal structure is well in place to support the business of ITunes and HMV. Economical Economy and business cycles affect the business. We are in the middle of an economic recession. Customers will be counting every penny they spend. The most the costs associated with dealing a company the more the customers shy away from that company. HMV: The costs associated with purchasing content from HMV are far more compared to buying music from iTunes. Customer needs to visit a store, browse through a variety of catalogues before zeroing on the music / video to buy. This involves time and travel cost. ITunes: customer can access iTunes by sitting in their homes. Carry the music with them in an iPod. Buying a single song instead of buying an entire album is always cheaper. Political Political changes are related to the influence that government has upon the industry. The political changes usually do not affect much the entertainment industry. In rare cases the governments may feel that some music / video content may be decided to be inappropriate for their country or will hurt the sentiments of the people. They ban the particular content from distribution and delivery. Technological: If there is any singular factor that changed the dynamics of an music industry, it is technology. With the ubiquitous internet, people are able to share digital content freely, which includes music, videos etc. Technology also facilitated the illegal copying and distribution of music and video. Technology also deintermetized the content delivery. As the music is directly delivered to the consumers there is no need for the manufacturers or suppliers of CDs/ DVDs. Technology made it possible to carry the content with us in our IPods, Laptops, Phone etc. Digital content everywhere and on any device is the MANTRA of technology. Companies that fast adapt to this tsunami of technology changes survive while others perish. BCG MATRIX: Boston Consulting Group (BCG) MATRIX is developed by BRUCE HENDERSON of the BOSTON CONSULTING GROUP IN THE EARLY 1970s. According to this technique, businesses or products are classified as low or high performers depending upon their market growth rate and relative market share ITunes: Growth: The Itunes is the undisputed star in the BCG matrix . Between 2000 and 2009 the population using internet has become 1.7 billion from 360 million5. High internet users mean high growth potential for the itunes. Cashflows: Itunes revenues are steadily increasing every year. Strategy: The strategy to be adopted for stars is to hold or invest for growth. Apple is investing in ITunes store by adding app store, which sells games and applications for mobile and computers. With the launch of Ipad Apple is adding the fastest growing segment , eBooks to iTunes , calling it as iBook store as a part of Itunes. HMV: Growth: The growth of the HMV stores has been moderate and better. The increase in sales also partly due to the demise of its closest rivals like Zavvi , Woolworths6. Cashflows: The cash flows for the physical stores are steady but not exactly encouraging. The online stores sales are increasing, hmv.com grew by 16% and waterstones.com grew by a phenomenal 60%7. Strategy: The recommended strategy is to hold or add market share. The company is losing sales as well as sales in the physical stores domain but is growing in the online space. That is why HMV is launching its own delivery of music and other content through direct download from its own website. Shopping Experience: The shopping experience is diametrically different for both HMV and itunes HMV Customer has 2 ways of interacting with HMV. A physical store visit and through online at the website of HMV for purchasing content. its own web site, which operates a sales model of e business. Customer can walk into the HMV stores, touch and feel the products and buy them. This is required especially while buying products like cards and posters. They can seek assistance from the store assistants, whenever they need it. When a customer visits the website www.hmv.com he can buy CDs that are delivered to him by post. When a customer buys any product directly from the store he can use it immediately, but when ordered online using the stores, he needs to wait till he receives the product by post to start using the product. The payment methods are cash or card for physical store payments and only through cards for online payment. ITunes To be a part of ITunes customers need the following: 1. A computer 2. Access to Internet 3. Download iTunes software 4. Have credit / Debit card 5. Error free internet connection. Customers are connected virtually. Customers can search the item they are looking for in no time. Customers can buy the item and start using them immediately, no need to wait for any shipment to arrive. The payment method is only through cards and NO CASH payments. Pricing of goods: HMV: The pricing of goods is entirely dependent on the content (CD/ DVD) that customer is going to buy. Music is sold through albums and the price is fixed per album. The individual items in a Music album or individual episodes in a TV show are not available for purchase. ITunes: The items are sold as bundled products like albums or sold separately as individual items. For example a customer wanting to buy music has an option of buying the complete album or individual songs in the album. Return Procedures: HMV The return policy is dependent on the kind of product purchased. Unwanted, damaged and incorrect or faulty items can be returned to HMV and customer can get a refund or get a damaged item replaced. ITunes When shopping with the iTunes Store, all sales are final. The customer needs to decide what are the items he wishes to buy and add them to the shopping cart. As soon as he clicks the BUY button, the purchases are charged to his account. The money is taken from his debit or credit card account. Once the order is placed there is no way a customer can cancel the order or get a refund. It is the responsibility of the customer to check for compatibility of the items purchased. Type of technology for website: HMV: The technology used by the HMV is * A browser interface for content viewing, no need to for any software (like iTunes). Anyone can view the content with the help of popular browsers like IE, Firefox or Chrome. * Order acceptance via website. No user account needed for buying items from HMV.com * Handles acknowledgement of payment and shipment delivery details for the order ITunes: The technology used by ITunes is Apple proprietary. Items are not sold through a web browser interface like other ecommerce sites. Anyone wanting to access ITunes need to download the software from APPLE and all the actions are through the software. The ITunes comprises of: * An interface for viewing the music/ video catalogs * An order processing system via iTunes account and credit card/ debit card * A delivery system via download from iTunes. ITunes restricts the sale of digital content to those people who are not having iTunes software. HMV and ITunes and E-Business Ladder Technology has changed the way the business happens. E-business is any process that a business organization conducts over computer-mediated network channels. Business organizations include any for-profit, governmental, or non-profit entity. Examples of these processes are on-line purchasing, on-line sales, on-line logistics, customer support, employee training and recruiting, and vendor-managed inventory, production design and control 8. The e business ladder is the ladder that shows where the organization stands with respect to what is possible to achieve in terms of available technology. The ladder shows how effectively the organization is using the advantage of technology and has integrated with business strategy. We will see where HMV and ITunes stand with respect to e -business ladder model of Cisco e-Adoption Ladder (DTI, 2000) HMV needs to move up the ladder to compete with Itunes. HMV is making moves towards this. HMV is adding another business dimension to its website www.hmv.com. The new delivery channel is by means of downloads directly from the website of HMV. This is currently under construction and will be available soon9. Which means HMV is moving up the ladder from just taking orders online and processing them offline to accepting orders and delivering through internet. ITunes is at the top of the ladder. It has tie ups with all leading content providers (music production companies, TV studios, movie producers etc). The customers just need to visit iTunes store to buy any content. This is a seamless integration of suppliers and buyers by iTunes acting as a intermediary facilitating B2C transactions. Emerging Technologies in e-business The emerging technologies that can be used for e-business are * Cloud computing * Mobile computing. ITunes has already made inroads into mobile computing by offering iTunes in its iphone. But iTunes is available only for iPhones. HMV can use the other platforms for mobile computing like Android from Google, Windows Mobile from Microsoft for building applications to sell content on mobiles. Cloud computing is the area that both iTunes and HMV needs to explore. The current business model is delivering the content to the customer by means of download or physical delivery of CD/DVD. Apple restricts the number of machines that can play the content that is downloaded from iTunes. We cannot play the content on more than 5 machines and those machines need to be authorized using the users iTunes account. With cloud computing the content is not necessarily delivered but it can be accessed from anywhere when connected to internet. A customer who buys a music album or songs need not download it to his computer but can access from anywhere and from any computer or any device, say , mobile. Cloud computing is possible only when the connectivity is always established with internet, which is not impossible in near future. How can HMV and ITunes increase market share HMV 1. Showing growth in the existing websites which is possible by new offerings like making downloads available 2. Introducing new product range like selling e readers and new gaming hardware like DSI 3. Introducing loyalty cards. 4. Strong tie up and product sharing with group company Waterstones for selling books and eBooks. 5. Live ticketing , HMV wants to sell tickets for events of the artists along with albums. 6. Starting Pay to Play gaming centers as the new gaming fever catches up across all age groups for games like Call of Duty. ITunes 1. Make it accessible to more people, via browser interface. 2. Make eBooks available 3. Remove the restrictions on the usage of the content bought from iTunes. Conclusion There are valuable lessons to be learnt from the strategy and models adopted by HMV and ITunes. Companies need to be aware of the forces that affect their business including competitors, customers, technology, suppliers, and at times most importantly new entrants into the market. The ITunes has once again proved that, the how ever dominant is the firm in the market it is never safe. Companies must be aware of the technological circumstances that surround the business in order to be on the cutting edge of new developments in the market. New entrants must also be aware of the technology that can give them the advantage over firms that are already dominating the market. Disintermediation is one important way that firms can use technology to streamline production and increase profits. And most importantly, a firm must never become complacent; they must always be on the lookout for new markets in which to expand.

Humans Activity And Climate Change Environmental Sciences Essay

Humans Activity And Climate Change Environmental Sciences Essay Climate change has been occurring on the planet for billions of years since its inception. At different times it has been caused by a catastrophic global event or by the dynamic inner workings of the earth. These climate changes have been proven by science over long periods of time. The big question these days is whether human activity such as the burning of fossil fuels is a major contributor to the climate change of the planet In 2007, the Intergovernmental Panel on Climate Change, stated that human activities contribute to climate change by causing changes in Earths atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contributing human activity comes from the burning fossil fuels that release carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and outgoing infrared (thermal) radiation that are part of Earths energy balance. Along with the change in temperatures come heat waves, new wind patterns, worsening drought in some regions, heavier precipitation in others, melting glaciers and Arctic ice and rising global average sea levels. A collaborated effort by hundreds of climate experts and government representatives from 113 countries, believe that climate change is caused by human activities. Most of the observed increase in globally averaged temperature since the mid-twentieth century is very likely due to the observed increase in anthropogenic (human-caused) greenhouse gas concentrations. Climate change is real, rapid and humans are playing a large part in transitioning to a warmer world. Human Activity and Climate Change When I turn the television on, and surf the news channels I get a quick snap shot of the latest events that have unfolded. At any given time Ill be informed of the latest earthquake, tsunami, flood, tornado or drought thats taken place while I was away. I dont remember these uncommon events being in the news as often as they have been. Not only that but they have been more violent as well. The increases in these events are sure indicators that a climate change is occurring on the planet as we speak. Climate change is defined as any long-term significant change in the weather patterns of an area. This has been occurring on the planet for billions of years since its inception. At different times it has been caused by a catastrophic global event or by the dynamic inner workings of the earth. These climate changes have been proven by science over long periods of time. The big question these days is whether human activity such as the burning of fossil fuels is a major contributor to the climate change of the planet. (Desonie, 2012) Humans have reached a level of knowledge and technology that allows us to detect a change in climate, identify the causes and consequences for that change. For example, I live in Twentynine Palms, CA which is located in the Mojave Desert. Climate changes here show a slow warming of the Mojave and Sonoran Desert regions. This warming is altering rainfall and weather patterns, altering plant cover and productivity, plus affecting ecosystem functions and species distribution. Desert ecosystems are predominantly sensitive to changes in atmospheric carbon dioxide. Future rises in atmospheric carbon dioxide will affect rates of plant photosynthesis and water loss, and are predicted to increase efficiency and productivity in certain desert plants. Increased plant productivity, particularly the productivity of invasive grasses, will increase the occurrence of wildfires in the desert. Increased severe and persistent droughts are also predicted for these desert ecosystems. (Webb, 2009) So, sim ply said climate change is already having and will continue to have major implications for plants, wildlife species, and ecosystem processes in this particular region. In 2007, the Intergovernmental Panel on Climate Change, stated that human activities contribute to climate change by causing changes in Earths atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contributing human activity comes from the burning fossil fuels that release carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and outgoing infrared (thermal) radiation that are part of Earths energy balance. (Solomon, 2007) Along with the change in temperatures come heat waves, new wind patterns, worsening drought in some regions, heavier precipitation in others, melting glaciers and Arctic ice and rising global average sea levels. (Hogan, 2007) A collaborated effort by hundreds of climate experts and government representatives from 113 countries, believe that climate change is caused by human activities. Most of the observed increase in globally averaged temperature since the mid-twentieth century is very likely due to the observed increase in anthropogenic (human-caused) greenhouse gas concentrations. (Solomon, 2007) Climate change is real, rapid and humans are playing a large part in transitioning to a warmer world. Studies have shown that humans have been burning fossil fuel at an alarming rate. By burning fossil fuels to produce energy to run vehicles or provide electricity, we emit carbon dioxide. Carbon dioxide has been scientifically proven to have harmful effects on the earths atmosphere. (Roach, 2007) The causes and effects of humans burning fossil fuels are easy to understand. By burning fossil fuels we emit carbon dioxide; carbon dioxide in turns depletes our ozone layer. The ozone helps block some of the suns heat and radiation. Without the ozone layer more sunlight, sun heat, and sun radiation reach the surface of the earth. This immediately means warmer temperatures. Warmer temperatures cause climate change. A very simple concept to understand yet the average individual seems to have a nonchalant attitude towards this fact. Granted natural climate change has been occurring for billions of years, but I believe that humans are greatly influencing the current climate change by our own activities. The industrial era for the human race began around 1750 and since this point in time we have been affecting the climate in many ways not known until recently. I also believe that humans are not concerned enough with the consequences that will result from our continued pollution of the earth, I am very surprised with the lack of urgency on our part. (Desonie, 2012) We produce four main greenhouse gases that possibly affect climate change, CO2 (carbon dioxide), CH4 (methane), N2O (nitrous oxide), and halocarbons. All of these types of gases contribute to the depletion of the atmosphere, but CO2, is the one mainly produced from the burning of fossil fuels. Levels of these gases have increased significantly since the industrial era, and are attributed to human activities. Changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system. (Solomon, 2007) Given the time and resources, there is no limit to what the human mind can do. Unfortunately, much of the knowledge and technology that has been used has had a negative impact on the environment. Yes, climate change is a natural occurring phenomenon as well but we have long been burning fossil fuels use before we understood the consequences. All pollution thats been levied upon the earth was cause by the human animal. So, my answer to the question of whether human activity, especially the burning of fossil fuels, is a major contributor to climate change is, yes, we are.

Disease and disorders affect a vast amount of lives in today’s world. Diseases are conditions that affect normal functions of the body. Many diseases and disorders are still being discovered and explored by scientists. One disorder that can disturb a person’s daily life and events is Generalized Anxiety Disorder also known as GAD. Generalized Anxiety Disorder is a disorder causing constant and often unrealistic worry and anxiety. It alters the way a person thinks and can ultimately lead to physical symptoms. This disorder, while having many physical and emotional affects, can be managed and maintained. Pathophysiology Worry, doubt, irritability, exaggerated anxiety, and unexplained tension are just a few of the many effects of Generalized Anxiety Disorder or GAD. While the symptoms aren’t life threatening, they remain unpleasant to control and many feel so overwhelmed, this can lead to patient’s use of substances and occasionally suicide. Though the cause of this disorder remains unknown, the main source of GAD comes from the brain. Genetics, Brain chemistry, and environmental factors are believed to be the main causes of onset of GAD. â€Å"Trauma and stressful events, such as abuse, the death of a loved one, divorce, changing jobs or schools, may lead to GAD†(WebMD: Anxiety & Panic Disorders Health Center, 2012, p.2). The neurotransmitters tell the brain how to feel and react. Many neurotransmitters have been connected to this disorder, including serotonin, GABA, and Norepinephrine. When hormones become thrown off or unbalanced this can also trigger Generalized Anxiety Disorder. Calm Clinic: Neurotransmitters and Anxiety states (2013), â€Å"Interestingly, too much or too little of any hormone may also affect anxiet... ...d health professionals as well. Medical practitioners encourage healthy habits, such as an exercise plan, to push the body to producing and releasing more endorphins. The medical provider may also recommend life style changes and that the patient find a hobby to preoccupy those anxious thoughts. There are many options available to help a patient deal with this illness. Generalized Anxiety Disorder is becoming more commonly recognized every day by healthcare providers; therefore the physical and mental symptoms are becoming more easily managed. The worrying, stress, and physical symptoms brought on by GAD can be treated with many options, previously not available. While an untreated patient may feel hopeless and helpless, with a treatment plan created by healthcare professionals, a person can feel like they are in control of their mental status and life again.

Choosing a Career Path Essay -- building management

Never once was there a doubt in my mind that I wasn’t going to college. But the question as to what career path do I want to pursue was always the hard part. When declaring my major, I had no idea that Michigan State had so many different options. My original major was pre-law, and then it was general management, now I’m leaning towards construction management. I watched â€Å"A Family That Preys† by Tyler Perry, and one of the characters was a construction manager. Like a child, watching this movie persuaded my decision to go into this field. I didn’t declare this as my first major because I was uneducated on the field, so I went with a major that I knew about. I am only in my second semester of college and I have changed my major twice. My uncle has been very successful and he has greatly inspired my choice of continuing my education. He was a successful insurance agent at state farm, and then went on to owning his own insurance company. Even though he i s in the insurance field, he is going back to school for trucking and looking into construction as well. One night we sat at my grandmother’s dinning room table and discussed my future career plans. I told him that I was interested in construction management but I was uneducated in the field so I didn’t change my major yet. I need to educate myself about being in the construction field by reading books, interviews, magazines, etc. The name construction management in itself sounds like a hand full, there’s no question that pursuing this major will be a lot of hard work and dedication. When I looked up the course requirements, the requirements reinforced my preconceived notations about this field. Calculus, microeconomics, and accounting, sounds scary and they are only 3 of the 120 cr... ...MSU RO:Academic Programs: Construction Management." MSU RO:Academic Programs: Construction Management.
