Government Internet Intervention Essays - Content-control Software

Government Internet Intervention Government Internet Intervention The Internet is a method of communication and a source of information that is becoming more popular among those who are interested in, and have the time to surf the information superhighway. The problem with much information being accessible to this many people is that some of it is deemed inappropriate for minors. The government wants censorship, but a segment of the population does not. The Internet should not be considered a bad source for people, considering all the uses and information it distributes. During the past decade, our society has become based solely on the ability to move large amounts of information across large distances quickly. Computerization has influenced everyone's life. The natural evolution of computers and this need for ultra-fast communications has caused a global network of interconnected computers to develop. This global net allows a person to send E-mail across the world in mere fractions of a second, and enables even the common person to access information worldwide. With the advances with software that allows users with a sound card to use the Internet as a carrier for long distance voice calls and video conferencing, this network is the key to the future development of technologies. At present this net is the image of the First Amendment: freedom of speech. It is a place where people can speak their mind without being reprimanded for what they say, or how they choose to say it. Recently, Congress has been considering passing laws that will make it a crime punishable by jail to send vulgar language over the net. The government wants to maintain control over this new form of communication, and they are trying to use the protection of children as a smoke screen to pass laws that will allow them to regulate and censor the Internet, while banning techniques that could eliminate the need for regulation. Censorship of the Internet threatens to destroy its freelance atmosphere, while methods such as encryption could help prevent the need for government intervention (Levy 56). The current body of laws existing today in America does not apply well to the Internet. Is the Internet like a bookstore, where servers cannot be expected to review every title? Well, according to an article written by Michael Miller in PC Magazine, The Internet is much more like going into a book store and choosing to look at adult magazines (Miller 75). The Internet differs from other forms of media. In that one cannot just happen upon a vulgar site without first, either entering a complicated address following a link from another source, or by clicking on the agreement statement at the beginning of the site acknowledging that one is of the legal age of 18. This lawless atmosphere bothered many people. One such person is Nebraska Senator James Exon (D), who is one of the founding fathers of the Telecommunications Decency Act of 1996 which regulates any obscene or indecent material via the Internet to anyone under 18 years of age.? Exon's bill would also according to an article written by Steven Levy in an April 1995 issue of Newsweek magazine criminalize private mail, Levy also stated emotional I can call my brother on the phone and say anything-but if I say it on the Internet, it's illegal (Levy 55). One thing that Congress seems to have overlooked in its pursuit of regulations is that there are no clear boundaries from information being accessed over the Internet from over countries. All it takes is a click of a mouse to access, even if our government tried to regulate information accessed from other countries, we would have no control over what is posted in those countries, and we would have no practical way to stop it. Today's Internet works much like that of our own human brains. In that if one barrier or option is taken, your brain tries to find an alternate route or option. Today's Internet works on a similar design, if a major line between two servers say in two countries, is cut, then the Internet users will find another way around this obstacle. This process of obstacle avoidance makes it virtually impossible to separate an entire nation from indecent information in other

Sacagawea essays

Sacagawea essays Sacagawea was a crucial part of the Lewis and Clark expedition. At first she was just their translators 15 year old pregnant wife, but turned out to be much more. She was a very good icon for the natives that they were encountering. The natives saw a young native woman that had a young child and knew they were not in any danger. (pg 164) There were also many times when they didnt have any food and Sacagawea picked the right roots and berries to keep them from starvation. She was mostly noted for saving precious instruments, gathered food, recognized important geographical signposts, and interpreted on numerous occasions. (pg 165) Unfortunately the diaries that were kept by the others on the journey do not talk about her personality or her opinions on many things. In other hostile situations Sacagaweas presence calmed the men and seeing the woman was like a sign of peace. She was also very important because she knew her way around and was very useful as a navigator. Sacagawea was never really acknowledged by the party because, in my opinion, the diaries that were kept were never accurate when describing her. She was not in a lot of them or only talked about as a translators wife. I dont think she was ever compensated because she was a young woman and a part of a different culture. During that period of time, women were not as respected as men, unfortunately. I think if she was European and male, she would have gotten a ton more appreciation, but then if she was a man, she couldnt have done some of the things that she did. ...

Political Fiction Essay Example | Topics and Well Written Essays - 2500 words

Political Fiction - Essay Example It can serve as a weapon towards change in a prevailing social system, tackle direct social and political repercussions, and discuss social struggle. Fiction can employ a particular topic and convey meaning and symbol related to an existing social and political system. The significance of fiction in history is not only confined within the realm of literature, but also explores the domain of politics. Fiction is seen to have worked its way in the political domain when Ignacio Salome's novel; Fontamara (1933) became popular upon gaining a favourable opinion of Mussolini's Fascism (Hanne 1994). Likewise, Alexander Solzhenitsyn's One Day in the Life of Ivan Denisovich (1962) personally authorized for publication by Soviet leader Khrushchev in order to discredit Stalin, is another example of fiction being influenced by politics. However, this connection is not limited to external influencing but extends to the more important functions of fiction and politics - that of the conveyance of meaning and symbol of political phenomena through their depiction of the fiction. Likewise, the realm of politics is likened to a fiction, including all its elements from plot to setting, characters, and scenes. Such is made possible through political representation embo died in the fiction, especially when it is a political novel. The Problems with Political Representation It is from assumptions, biases, and news reports from which political beliefs are normally spring, which makes politics a drama that takes place in an assumed world in which people as spectators, do not directly observe or touch. Politics is a domain that consists of images and models wherein people usually translate the reported news, a task considered a necessary undertaking (Edelman 1995). Edelman says that this translation is seen in an example in which a report about American missiles were launched against Baghdad to punish the Iraqi dictator which creates meaning for everyone's repertoire on the images of images of military actions, Arabs, and how war brings devastation even to civilians. Political phenomena are thus not taken as they are without any political representation involved. More so, political representation is an essential part of how symbols and messages are conveyed, in that in another example set by Edelman (1995), a report about an increase or reduction of welfar e benefits brings images of cheaters and victims, as well as the possible consequences of such increase or reduction in relation to tax rates, and so on. These are examples of political images being drawn on the minds of people caused by attached meanings and assumptions on them. Political fiction often offers direct criticism of a present government, society, or political figure and presents an alternative of a sometimes fantastic reality, to what is being criticized (Edelman 1995). In doing such, political fiction often employs satire like The Simpsons in its depiction of the Western culture. It may be inferred that beliefs about politics and political discourse are products of art in which complex causal connection is drawn. This being said, Edelman states that art is a

The Marketing of Services Essay Example | Topics and Well Written Essays - 2000 words

The Marketing of Services - Essay Example In addition, the economic down turn in the United Kingdom and the rest of the world caused increased levels of uncertainty and unemployment among the potential customers. The impact was a reduction in the consumption of the discretionary services offered by the enterprises in the sector. These changes in consumer behavior have affected several music retailers further aggravating the decline that was being experienced in an already underperforming sector. Prior to the financial crisis, various industry players had been facing financial difficulties due to the shifting interest of consumers from the musical services to computer games. However, things look bright as the sector continues to recover albeit at a slow pace. In the music retail industry, there are several retailers and enterprises covering the entire United Kingdom. They include single stores, independent outlets and chains of retail stores. This gives a wonderful mix of shops dealing in a variety of services. Services like instrument hire, music recording, repair of educational establishments, music teaching and site music facilities are offered in the shops. Some of the major competitors include Asda Group limited, HMV, Woolworth Group Plc, Virgin Books Ltd and Play.com. Others are AA Music, Academy Chimes Music and Ackerman Music Limited. Most of these retailers have been affected by the recent decline in purchases. HVM remains the leading retailer in the United Kingdom. Just like any other service sector, the music retail industry faces a number of problems coming from the nature of services which are offered (Dotchin & Oakland 2004). The five service characteristics are helpful in understanding some of these major problems. Perishability is perhaps one of the most difficult characteristic of the services in this sector to appreciate (Porters 2005). Services are highly perishable compered to physical products. This can be best understood when one considers the kind of services that enterprises such

Literary analysis of Cathedral Essay Example | Topics and Well Written Essays - 500 words

Literary analysis of Cathedral - Essay Example Furthermore, the close relationship between his wife and the blind man that existed through the years provided additional ire and ill feelings. The transcending climax in the plot revealed how Robert, despite his blindness, was able to actually open the mind and constricted perspectives of the narrator through a unique experience of the cathedral. The characters of the story are the narrator, as the protagonist, whose instrumental point of view revealed details of the plot. As the narrator, he is considered a round character, where his personal views and feelings towards other characters are relevant in the development of the story. He foretold the experience of his wife, unnamed, yet instrumental in inviting Robert to their home. The wife is a flat character, through described in more details, as necessary to advance the events that are about to unfold. The blind man, Robert, is initially seen as the antagonist, providing conflict to the narrator due to the impending visit that he o penly disliked. The story told in a straightforward style, manifests diverse symbolism in terms of the cathedral, itself, as a manifestation of strong and steadfast faith as giving immense ability to transform a nonbeliever into a brand new person with optimistic perspectives. Through the cathedral as the impetus for discussion between Robert and the narrator, an eye-opening transformation for the narrator ensued.

Shape Memory Alloys Research

Shape Memory Alloys Research 1.1 General considerations When a regular metallic alloy is subjected to an external force greater than its elastic limit, it deforms plastically, i.e. the deformation persists after returning to the unloaded state. The Shape Memory Alloys (SMAs) do not follow this behavior. At low temperatures, an SMA specimen may undergo a plastic deformation of about few percent, and then fully recover its initial shape that had at higher temperature by simple heating above a threshold temperature. Their ability to recover their form when the temperature is raised, makes this class of materials unique. This phenomenon has been discovered in 1938 by researchers working on the gold-cadmium alloys [Gilbertson (1994)]. The shape memory effect remained a laboratory curiosity until 1963, when the first industrial and medical applications appeared. 1.2 Martensitic Transformation The shape memory effect is based on the existence of a reversible phase transformation of thermoelastic martensitic type [Kurdjumov, Khandros (1949), Kumar, Lagoudas (2008)], between a microstructural state at high temperature (austenite phase) and a microstructural state at low temperature (martensite phase) [Patoor et al. (2006), Lagoudas et al. (2006)]. Austenite has in general a cubic crystal lattice, while martensite is of tetragonal, monoclinic, or orthorhombic crystal lattice. The transformation from one crystal lattice to the other occurs by distortion of the shear lattice does and not by atoms diffusion. This type of transformation is called martensitic transformation [Perkins (1975), Funakubo (1987), Otsuka, Wayman (1999)]. In reality, the matrenitic transformation in SMAs is a phase transformation of the first order, where there is co-existence of several phases, and there is presence of interfaces between the phases [Guà ©nin (1986)]. Historically, the term martensitic transformation describes the transformation of the austenite of steels (iron-carbon alloys) to martensite during a quenching. By extension, this term has been generalized to a large number of alloys whose phase transformations have certain characteristics typical of the transformation of steels [Rosa (2013)]. During martensitic transformation of a SMA, the crystal lattice of the material changes its shape. The microstructure of martensite is characterized by a change in shape and by the difference in volume, which exists between matrensitic and austenitic phase [Duerig et al. (1990)]. Therefore, internal strains arise during the emergence of martensitic areas within the austenite. The internal strains can be partially relaxed by the formation of several areas of self-accommodated martensite crystals that minimize the overall deformation induced. These areas called variants and are oriented in different crystallographic directions [Kumar (2008)]. In the absence of external strains, these variants are equally possible and the distribution of self-accommodated groups allows the material to be transformed in order to retain its original shape. Therefore, the formation of the martensite results in elastic (reversible) deformations [Funakubo (1987)]. At constant temperature, the martensite-austenite interfaces are in steady state. A change in temperature in one direction or the other results in moving these interfaces to the benefit of one or the other phase structure. The interfaces can also move under the action of an imposed strain. A specimen can therefore be distorted not by sliding, which is the usual mechanism of plastic deformation, but by the appearance and disappearance of martensite variants [Kumar (2008)]. Therefore, during martensitic transformation atoms in the structure move on very small distances leading to deformation of the crystal lattice. This causes a small variation in volume with shearing of the structure in a specific direction. During the transformation process, the growth of martensite crystals occur in form of platelets to minimize the energy at the interface. The martensitic variants can occur in two different types: twinned martensite (formed by combination of self-accommodated martensite variants) and detwinned martensite (reoriented martensite) where a particular variant dominates [Liu, Xie (2007)]. The characteristic behavior of SMAs is based upon the reversible phase transformation from austenitic phase to martensitic phase and the opposite. By cooling under zero loading, the crystal sructure changes from austenitic to martensitic phase (forward transformation to twinned martensitic phase). This transformation is resulting in the development of a number of martensitic variants, which are arranged in a way that the average change in macroscopic shape is insignificant, causing a twinned martensite [Leclercq, Lexcellent (1996)]. When the material is heated at the martensite phase, the crystal structure is transforming to austenite (reverse transformation from detwinned martensitic to austenitic phase), leading to recovery of shape [Sabu ri, Nenno (1981), Shimizu, Otsuka, Perkins (1975)]. The above process is called Shape Memory Effect (SME) [Schetky (1979), Wayman, Harrison (1989)]. The martensitic transformation is characterized by four temperatures (Figure 2) [Gotthard, Lehnert (2001)]: MS: Temperature below which the martensite appears (martensite start) MF: Temperature below which the entire sample is transformed into martensite (martensite finish) AS: Temperature above which the austenite appears (austenite start) AF: Temperature above which the entire sample is transformed into austenite (austenite finish) The transformation begins at the cooling to the temperature MS. This transformation is completed to the temperature MF. Between these two temperatures, there is coexistence of two phases, which is a characteristic of transformation of the first order. If the cooling is interrupted, the material will not change. To go back to the initial shape, the temperature is increases so that the inverse transformation begins at the temperature AS and finishes to temperature AF, which is higher than MS [Massalski et al. (1990)]. If the trace on a diagram (Figure 1) the volume fraction of material processed as a function of temperature, there is a hysteresis loop, due to the presence of an irreversible energy corresponding to dissipation of mechanical energy transformed into heat [Ortin, Planes, Delaey (2006), Wei,Yang (1988)]. Figure 1 Martensitic transformation temperatures [Gotthard, Lehnert (2001)] The thermoelastic reversibility of the crystal lattice is certain in the case of an ordered alloy [Otsuka, Shimizu (1977)]. The correlation between the manifestation of martensitic transformation and atomic order was shown experimentally in Fe-Pt SMAs [Dunne, Wayman (1973)]. Nevertheless, in disordered alloys, such as Fe-Pd, Mn-Cu and In-TI, can occur thermoelastic transformation too. The atomic order is, therefore, a sufficient condition for manifestation of thermoelastic transformation, but not necessary [Otsuka, Shimizu (1977)]. 1.3 Thermomechanical properties of SMAs Several effects specific to the SMAs appear through the transformations of the crystal lattice as a function of temperature and of the field of stresses applied on the material [Duerig, Melton, Stà ¶ckel (2013)]. 1.3.1 Pseudoelastic Effect In general, by pseudoelasticity we describe both the materials superelastic behavior, as well as rubble-like behavior. Superelastic behavior is called the reversible phase transformation produced by thermo-mechanical loading. Rubber-like effect refers to the reversible martensitic re-orientation. The stress-strain curve during this process resamples to the superelastic behavior, which is similar to rubbers nonlinear elastic behavior [Otsuka, Wayman (1999)]. Therefore, a part from inducing phase transformation thermally, martensitic transformation can also be prompt by applying on the material appropriately high mechanical loading, resulting in creating a martensitic phase from austenite. When the temperature of the SMA goes above AF, shape recovery is resulted while unloading. Such behavior of the material is termed pseudoelastic effect [Kumar (2008)]. Stress-induced martensite, is generally forming from austenite when external stress is present. The process of forming stress-induced martensite can occur through different thermomechanical loading routes [Miyazaki, Otsuka (1986)]. One form of stress-induced martensite is the detwinned martensitic phase formed from austenitic after application of external stress. The material, during the stress-induced martensitic transformation and the reversed process, shows nonlinear elastic behavior described by closed à Ã†â€™-ÃŽÂ µ curves. This nonlinear elastic behavior is called pseudoelastic transformation [Otsuka, K. and K. Shimizu (1981)]. The shape recovery is due to crystallographic reversibility of transformation, like in the shape memory effect. Hence, the two phenomena, transformation pseudoelasticity and shape memory effect are practically the same except the fact that reverse transformation is produced by warming the specimen to temperature above AF. In reality, an alloy that un dergoes thermoelastic martensitic transformation exhibits both transformation pseudoelasticity and shape memory effect [Otsuka, K. and K. Shimizu (1981)]. Nevertheless, for occurring transformation pseudoelasticity, the necessary stress for slip should be greater than that for stress-induced martensite transformation. As an example, we can refer to equiatomic Ti-Ni alloys which are exposed to slip and do not exhibit any transformation pseudoelasticity, regardless of their Ni content. It was shown, however, that Ni-rich Ti-Ni alloys subjected to annealing after cold working, causing refining of their grain size, leads in raising critical slip stress, which results in any transformation pseudoelasticity [Miyazaki et al. (1982), Saburi, Tatsumi, Nenno (1982), Saburi, Yoshida, Nenno (1984)]. The existence of transformation pseudoelasticity is affected by crystalline orientation, composition of the alloy, and direction of applied stresses [Miyazaki, Otsuka (1986)]. 1.3.2 One-Way Shape Memory Effect Another property of SMAs is the one-way shape memory effect. It takes place in four steps: (1) The material is cooled to a temperature lower than MF (the parent austenitic phase) to obtain self-accommodated martensite. (2) Re-orientation of variants of the martensite is obtained via application of stress. (3) The stress is released at constant temperature T F. The material remains to a shape depending on the stress field. (4) The sample is heated at a temperature T > AF making re-appear the austenitic phase and the material gets its original shape, as shown in Figure 2. Figure 2 One-way shape memory effect [Miyazaki, Otsuka (1986)] Two conditions are necessary for occurring shape recovery by shape memory effect. Firstly, the transformation should be reversible, and second, slip should not occur during the entire deformation process. Martensitic transformations in ordered alloys are reversible in nature [Miyazaki, Otsuka (1986), Arbuzova, Khandros (1964)], so the entire shape memory effect mainly occurs in this type of alloys. The second condition is necessary because in the case of high stress and every type of deformation mode (stress-induced martensitic transformation in parent phase, twinning in the martensitic phase) slip can be induced, resulting in plastic strain and, not completed recovery of shape. In the one-way shape memory effect, the shape in memory by the SMA is the one of the parent phase. 1.3.3 Two-Way Shape Memory Effect The two-way shape memory effect is the reversible passage of a shape at a high temperature to another shape at low temperature under stress. The two-way shape memory effect should precede the SMA training [Nagasawa, et al. (1974]. Training of SMAs consists of temperature cycling at constant stress or stress cycling at constant temperature. During training, microstructural defects (i.e. dislocations) lead to internal stresses and therefore promote oriented martensite. A SMA subjected to training can then move from austenitic phase to oriented martensite under zero load by simple change of temperature [Schroeder, Wayman (1977)]. It has then a shape in memory for each of the two phases. Various methods that cause two-way shape memory effect have been suggested, such as, large deformation in stress-induced martensite transformation at temperatures > MS [Delaey et al. (1974)], shape memory effect training [Schroeder, Wayman (1977)], stress-induced martensite training [Schroeder, Wayman (1977)], training involving both of shape memory effect as well as stress-induced martensite [Perkins, Sponholz (1984)] remaining in martensite state while heating at a temperature > AF [Takezawa, Shindo, Sato (1976)], as well as using precipitates [Tadaki, Otsuka, Shimizu (1988)]. 1.4 Transformation Induced Plasticity (TRIP) Several experimental studies have shown the development of nonlinear plastic (irreversible) strain when phase transformations occur [Greenwood, Johnson (1965), Abrassart (1972), Magee (1966), Desalos (1981), Olson, Cohen (1986), Denis et al. (1982)]. This mechanism of deformation is termed Transformation Induced Plasticity (TRIP), resulting from internal stress rising from the change in volume related to the transformation, as well as from the associated change in shape [Marketz, Fischer (1994)]. TRIP differs from classical plasticity. Although plasticity is caused from the applied stress or variation in temperature, TRIP is triggered by phase variations, and occurs even at low and constant stress levels [Gautier et al. (1989), Leblond et al. (1989), Gautier (1998), Tanaka, Sato (1985), Fischer et al. (2000, 1996)]. TRIP takes place because of two separate mechanisms. The first, refers to a process of accommodation of micro-plasticity related to volume change [Greenwood, Johnson (196 5)]. The other, refers to an orientation caused by shear internal stresses, favoring the direction of preferred orientation for the formation of martensite when and external stress is present, which involves change in shape [Magee (1966)]. TRIP is caused by the difference in compactness of the lattice structure between the austenite (parent) and the martensite (product) phase [Greenwood, Johnson (1965)]. During martensitic transformation, this difference has produces a change in volume as well as internal stresses causing plasticity in the phase with less yield stress, which is weaker   [Paiva, Savi, Pacheco (2005)].

Parents of Pre-term Infants Essay -- social workers, parental stress,

Article Review One The first article, Parents of Pre-term Infants Two Months after Discharge from the Hospital: Are They Still at (Parental) Risk? (Olshtain-Mann, O. & Auslander, G. K , 2008), describes a study in Israel that was designed to gain further understanding of † the emotional state and functioning of parents of pre-term infants, after an initial period of adjustment following the infants’ discharge from a Neonatal Intensive Care Unit (NICU)†. Specifically, this study compared the stress levels of parents and self-perceptions of competence as parents among mothers and fathers, two months after discharge of their babies from the hospital. The study compared parents of pre-term babies with parents of full-term babies. A target group of 80 pairs of parents of pre-term babies and a non-matched comparison group of 80 pairs of parents of full-term babies were interviewed for the study. Respondents were selected as follows: All couples (both mothers and fathers) in both groups were Hebrew speaking. The target group had pre-term infants who were hospitalized in the NICU of any of three hospitals in Jerusalem during 2001-2002. These premature babies weighed less than 3.85 pounds and were born in the 36th week or earlier. All were treated in the NICU for one week or more. According to the article, exclusions included parents of children who were not expected to survive or those who had congenital abnormalities. Parents of the full-term babies had infants who were born in the same time period, and in the same hospitals, as the target group. All babies in both groups were singletons. The interviews were conducted by social workers and followed a specific protocol. A further questionnaire was completed by both mothers and fa... ...e employed to develop programs that will offer support to the new parents of higher risk children.

Importance of a Small Class Size Essay

Wenyan Dong Writing 6 First draft Causes and Effects of Reducing Class Size Improving the quality of education becomes common trend today. People have made many ways to support education. Most of schools reduce the size of class that make more chances for students and teachers to communicate face to face. The reducing of class result from some courses and also makes some effects to teachers and students. The first significant cause is the attention from teachers is not equal to different grade students. Small class had origin in early years. Follow the increasing of population, small size class has become bigger. Recent research reveals that there were 50†60 students in one class, but Just one or two teachers advise class. It means that one teacher Just pay a little patient for each student in presentation, speech, question, and homework. Thus, many teachers pay more attention on students who have prefect grade and ignore students who have a low grade. It is not equal to low grade students because they pay same tuition and fee to school also study hard.. In addition, teachers who teach in a big class have to take a lot of work after class and exhaust them. They have to correct students’ homework for a long time. Also students ask many question after class if they do not understand, however, it exhaust teachers’ energy and patient and they don’t have enough time and disable to answer each question to each students. As a result, student could not get help immediately. Meanwhile, environment in class is important. Teachers could not control teaching environment in big class, because it is difficult to make students keep quiet and concentrate on blackboard whole time. Also students do not have enough personal environments, because it is crowd, usually two students have to share one big desk on big class, hence, there are no room for other hings but book. Due to those causes, it would decrease the quality of education, at the same time, lost a lot of labor cost, also waste time and money of students and parents. Thus, school reducing the size of class. It could make more time for teacher work for each student; furthermore, teacher can communicate with student face to face. In addition, it could make study environment better for students. Consequently, teachers who teach in small class do not need to do many assignments after class, even if they also need to make a correction about students’ homework, but they may have more time to be a tutor and help students who do not nderstand in the class. Meanwhile teacher could focus on the question for each student that would be equal for every student. Moreover, on being assigned to smaller classes, teacher reported that class atmosphere is better, that students could receive more individualized attention and that the teachers have more flexibility to use instructional approaches and assignments. To sum up, reducing the class size is inescapably. It leads to higher achievement of students and make more time improve the quality of education, but also make students and teachers keep touch closely. Therefore, reducing class size is good way for students and teachers.

Economic Simulation Reflection United Kingdom Economics Essay Essays

Economic Simulation Reflection United Kingdom Economics Essay Essays Economic Simulation Reflection United Kingdom Economics Essay Essay Economic Simulation Reflection United Kingdom Economics Essay Essay The impact of rising prices was illustrated in the game in a assortment of ways. First, when our state ( Great Britain ) experienced high rising prices in the early phases of the simulation due to high authorities disbursement degrees, we noticed that the exchange rate to change over British lbs into other currency was really low and that when we did exchange, we received really small in return of the other currency. This of class made trade highly expensive and as a consequence hard to construct substructure and derive indispensable resources such as nutrient that we were non able to bring forth. Second, lifting rising prices meant lifting monetary values and made other states avoid trade trades due to the high cost of our resources. The high monetary values drove other states to happen better trades elsewhere as they were non able to obtain good value as the small resources from our state would non hold been deserving their money. Consequently our state s grosss suffered as a consequence. Not merely had our grosss from trade trades suffered, but existent GDP fell in our state as a consequence of the uncontrolled rising prices exceling the GDP growing rate due to both, no disbursement ( as we had small money from no trade ) and few policy alterations to command the diminution of the economic system. Finally, due to rising prices take downing the criterion of life in a state, our workers went on work stoppage and non merely were we non able to, at times, even produce resources doing a loss in grosss and the inability to better substructure without obtaining resources elsewhere ( which was expensive ) . The impact of rising prices was demonstrated to us throughout the class legion times in pecuniary policy, and the economic construct that we experienced the most in the simulation was the construct of magnitude. The class construct of magnitude was seen at times as rising prices outweighed involvement, which led to less buying power with the British lb ( as experienced during the simulation ) and led to few resources being obtained by our state. Magnitude causes consumers to pass money now instead than subsequently as they realize that merchandises will merely be more subsequently down the route as the buying power of their money lessenings. This of class causes farther stimulation of the economic system ( at a clip when it would be un-beneficial and the chilling of an economic system is needed ) and further drives up cost of merchandises ( or resources ) and therefore increases rising prices even more to unmanageable degrees. The impact of rising prices and magnitude was experienced during the 1920 s in Germany where hyperinflation was so rapid, workers would be paid twice a twenty-four hours and given a half-hour deferral so that they could hotfoot out and purchase basically anything before the value of their money would drop and they were non able to feed their households[ I ]. Inflation in Germany even got to the point where the monetary value of the dollar ( in 1923 ) had risen to 381,700,000,000 % while the cost of life, as a comparing, had risen good beyond 560,000,000,000 % . Measured by how many Markss it took to purchase a dollar, monetary values were 222 times higher. The hyperinflation eliminated all debts that existed prior to 1921. For illustration, the value of German mortgages in 1913 measured in U.S. dollars was about $ 10 billion ; in late 1923 these mortgages were deserving merely one U.S. penny. These statistics illustrate non merely the quickly diminishing buying power of the German grade, but besides the badness of what is now considered to be one of the work rising prices crises of all clip. Importance of substructure During the simulation, the importance of substructure became progressively evident as during the initial old ages, monetary values of goods in our state began to lift and other states avoided trade trades. This of class cost us important gross, which made it progressively hard to raise capital and obtain necessities ( nutrient ) . Prior to bettering upon, and constructing our ain substructure nevertheless, we noticed that monetary values of resources in other states were steadily diminishing as a consequence of their substructure betterments, which at the same time caused the frequence of trade between these states and their Alliess to increase and doing them important net incomes. Once we began to better on our ain substructure following this observation nevertheless, which included roads, communicating, mills, and office towers ( for the corporate triumph status ) , we non merely found that monetary values of our goods fell, but besides, due to the fact that substructure is a signifier of authorities disbursement ; GDP began to lift. Along with authorities disbursement through the addition in substructure, the increased trade from our now lowered monetary values caused exports to other states to lift ( an injection to the round flow ) and allowed us to bring forth more net income at that clip. As a consequence of the initial alteration to lower monetary values of our resources, we besides noticed that due to our merchandises holding more demand as a consequence of lowered monetary values, our escapes ( chiefly imports ) were outweighed by our injections ( the addition in exports ) , which made that twelvemonth really profitable. This rise in GDP combined with the, at that clip, controlled rising prices, led to Great Britain s currency being deserving more in footings of exchange rate on the planetary market, and other states began to near us more often for resources. The importance of substructure is a fluctuation of the construct of economies of graduated table from the economic sciences class. Economies of graduated table provinces that the larger the production graduated table ( or in footings of the simulation ; the more mills and substructure ) , the cheaper the cost per unit as you are able to distribute to fixed costs of doing a merchandise ( resource ) over more units of production ensuing in less fixed costs per unit and a cheaper merchandise or in this instance, resource. In existent life the importance of substructure and the ensuing cost decreases are seen in an illustration from the United Kingdom ( besides the same state from our simulation ) . In the UK, the authorities had begun to increase the technology of air current turbines as a beginning of renewable energy in an attempt to cut the cost of electricity and go more efficient[ two ]. In the instance of renewable energy, economic systems of graduated table are a clear manner to cut down costs per unit and salvage money. The more energy you can acquire out of a individual device, the lower the cost per megawatt. If you build a 10MW turbine, instead than two 5MW 1s, you get important nest eggs in all of those and that brings your monetary value per megawatt down significantly. This of class was besides illustrated in our simulation through the pick of either constructing little or big production mills, which would change the cost of the resource produced, but changing in precisely the sum of nest eggs and the resources used to build in order to be the most efficient. Impact of revenue enhancements and disbursement The impact of revenue enhancements and disbursement were experient two different ways during the G7 economic simulation. First, as we raised revenue enhancements to counter the high rising prices experienced early on in the simulation, we found that resources became progressively expensive to buy and therefore as a consequence, the limited money that we had at that clip was non plenty to prolong us with indispensable resources and reinforced substructure at the same clip. This caused early stagnancy in the growing of our economic system and the growing of our corporation as the high cost of our ain resources prevented important GDP growing and enlargement. Second, as a consequence of high revenue enhancements, small disbursement from other states for our merchandises took topographic point for our resources and we experienced small gross from exports and small to no GDP growing early in the simulation as a consequence. The limited disbursement from other states for our merchandises had an consequence on our ain disbursement, as there was small money generated, and therefore small available for our ain state to pass. This disbursement quandary nevertheless was all a consequence of our initial high revenue enhancement rate as a method of inflationary restraint and the effort to happen a balance between commanding rising prices and take downing monetary values. During the initial old ages of the simulation we had besides noticed that other states who had low revenue enhancement rates, but besides lower rising prices, were merchandising among each other more often as the revenue enhancements on resources, and therefore overall cost was lower. This of class led them to do more gross and spread out their economic systems along with the corporation facet. Following this observation, our primary end was to command rising prices and instantly lower revenue enhancements to increase trade entreaty. The construct of revenue enhancements and disbursement was touched upon in the macroeconomics part of the class and specifically in financial policy. The construct of raising and take downing revenue enhancements by the authorities along with authorities disbursement are considered agencies of economic stimulation as they are considered both escapes ( revenue enhancements ) and injections ( authorities disbursement ) . We used this construct from the financial policy unit in our economic simulation in an attempt to advance economic stimulation with a revenue enhancement cut ( without making a deficit of grosss ) and besides attempted to increase authorities disbursement ( in moderateness to guarantee we still had adequate money left to buy indispensable resources ) . The financial policy unit outlined precisely what authoritiess would make in both bull and bear markets to either stimulate, or forestall farther growing and as we experienced both good and bad times during the simulation. We used the construct of revenue enhancements and disbursement to both stimulate and stagnate growing in our economic system when it was necessary. A existent life illustration of the execution of revenue enhancements and its consequence on disbursement can be seen in Australia as the authorities imposed a new revenue enhancement on crude oil doing the oil giants, unable to absorb all costs, to turn around and increase monetary values on consumers[ three ] In order to remain competitory, concerns seek to go through cost additions onto their clients. ( Microeconomics construct ) Despite gas being a necessity and the industry an oligopoly causation demand for the resource to stay comparatively changeless, more consumers will more than likely effort to cut down gas ingestion in order to diminish their disbursement following the revenue enhancement addition and the new, higher cost of the trade good. Why do we merchandise? What makes it possible? Necessary? As the simulation consisted of 7 states all holding entree to assorted sums of assorted resources, the ability for one state to prolong both their economic system and construct their corporation was non possible with merely the production of their ain resources. Therefore, as some states produced what others could nt, the demand for trade became progressively evident. Not merely, during the simulation, did all states commence in trade with at least one or more other states in order to obtain both indispensable, and excess resources for substructure and development of their corporation, but it became rather apparent that trade was the lone means for some states to go on to feed their population and basically run into their one-year demands. This became evident first manus to our state ( Great Britain ) as we were non able to bring forth nutrient and therefore had to trust on trade with other states every twelvemonth to get necessities in order to avoid farther loss of GDP as a end point punishment. Trade during the simulation was comparatively simple nevertheless, provided that adequate capital was raised to pay for the basal monetary value of the resource and the revenue enhancements set by each single state. No trade barriers, extra fees or duties, nor external issues were experienced during the simulation and therefore trade was both possible and highly good once trades and orders between states were established. As expected nevertheless, the states with the lowest monetary value of resources and lowest revenue enhancements ( such as the EU for several old ages ) were favorites by others for trade trades. This of class made them important gross and gave them first pick in measure of the resources that they required and subsequently obtained from such trade spouses. Merely in the ulterior phases of the simulation did certain states avoid trade trades with each other in order to cut off resources to certain states and as a consequence put strain on their ability to run into demands in an attempt to, basically seek and lower their GDP for a personal triumph status. This effort to cut off supply to other states illustrates some points from the class construct of Porter s 5 forces such as supply power, rivalry/ competition, and handiness of replacements. The construct of free trade from the economic sciences class was besides another chief factor in the trade trades between states in the simulation. Although non all states specifically specialized in the production of one peculiar resource, good dealingss between states allowed for the free trade construct to get down and most states found at least one other trade spouse who was able to provide them with what they required. Without the construct of free trade and specialisation nevertheless, both efficiency and wealth maximization would diminish, but the hazard of mutuality for states would besides fall, exemplifying both the pros and cons of international trade. An illustration of the importance, ability, and benefits of trade can be seen with the export of Canadian canola to the Chinese market[ four ]. It has been confirmed that China will widen its steps to let Canadian canola exporters to subscribe contracts with Chinese importers for extra canola to be shipped and traded. This is good intelligence for China, and both Canadian husbandmans and the Canadian authorities as Canola is one of Canada s most valuable exports to China, worth about $ 1.3 billion. This illustration illustrates both the demand for trade to have merchandises non able to be grown in China for illustration and the important grosss that would be lost had trade barriers and extra revenue enhancements been imposed on the Canadian goods. Specialization Specialization of resources during the simulation became indispensable in our states ability to run into the one-year demands of nutrient and oil. As we were non able to bring forth nutrient, we relied on our constitution of a trade trade with the EU, as they ever produced an copiousness of nutrient and therefore as a consequence provided us with a low monetary value and an one-year supply of what we required. Not merely had the EU experienced the benefits of specialisation from changeless trade and gross from our state, but our ain state besides realized the benefits of specialisation and produced more oil than we needed on an one-year footing in order to provide Japan as they ever proceeded to purchase from us. Our specialisation in oil production meant changeless gross from Japan, and gave us close ties with them for resources that they produced, which we needed. The construct of specialisation and free trade was covered in the international trade unit of the class and outlined the benefits of a state non holding to bring forth all the resources that they required doing states to specialise and merchandise with each other and as a consequence, maximising universe wealth. The lone issue with specialisation is interdependence as states begin to trust on merely one provider of a certain resource ( as they no longer need to bring forth it ) , which presents the possible hazard of supply coming to a sudden arrest and the importing state enduring economically. This class construct was besides experienced in the simulation as in the last 2 old ages, the EU began to cut Japan s supply of resources and they found it progressively hard to happen what they required as no other trade trades for that peculiar resource were established. In existent life the construct of resource specialisation can be seen with Iran being a universe leader in the export of oil ( ranked as the 2nd largest exporting member of the Organization of Petroleum Exporting Countries )[ V ]. The benefits of specialisation can besides be illustrated with the important grosss produced as a consequence of big markets. For illustration, Iran s primary export markets included Japan, China, South Africa, Brazil, Pakistan, Sri Lanka, Spain, India and the Netherlands, while oil grosss as a consequence of such extended trade accounted for 80 per centum of Iran s foreign currency grosss and 60 per centum of Iran s overall budget. This illustrates non merely the sum of wealth that a state may see as a consequence of specialising in the production of a certain resource, but besides the sum of other states that rely on states specialising in order to obtain resources for their ain usage and sale in their economic systems.

Nectar in a Sieve - Puli essays

Nectar in a Sieve - Puli essays Puli is first introduced to the readers in chapter 25 as a quick-witted and incisive ragamuffin whom for which his street know how is dually noted. The author states, He was an artful child in many ways, and more than a match for us (Markandaya 176). With a quick tongue and an acute mind he makes his day in day out routines seem facile, despite his distinct physical impediments. Fingers or no fingers, life is worth living for this child who takes advantage of every opportunity for self-gain and internal completeness. This urchin is brought into this novel with his sense of direction needing to be imparted upon a duo of country-bumpkins who obviously have no grasp of where there intended destination is. Puli assists in this operation, but not for free, for Puli is no ignoramus. Puli is incorporated into the final chapters of Nectar in a Sieve by residing with Ruku and Nathan. In order to provide a more blissful future for the couple Puli once again assists by providing employment for Ruku and Nathan. A career in stone breaking, this time a gift for free. A free donation, already showing the growing closeness between the couple and Puli. A new Puli is being formulated.

Understanding strategic management - Essay Example h of the global airlines and predicts $560 billion in its revenue with the net profits of about $8.9 billion, the European air sector is expected to have loss of $1.3 billion (IATA, 2010). In particular, the number of the UK airports’ passengers has fallen by 7.3% - the biggest fall in the overall history of records (Milmo, 2010). In spite of the all-European negative trend, the Ryanair’s business has been stable and strong – today the company reports about the growth in profits in â‚ ¬ 318.8 million over 2010 (RAa, 2010). As it is claimed in the Ryanair Annual Report 2010: â€Å"All the key indicators including traffic growth, market share, unit costs, profits, new route and base development, confirm that Ryanair continues to successfully roll out our unique low fares formula across Europe for the benefit of our passengers, our people and our shareholders† (RAa, 2010, p.6). However, one cannot but admit that the competitive environment of the global airline industry is changing dramatically, entailing challenges for even successful businesses. In order to respond appropriately to these emerging challenges, companies should constantly analyse, evaluate and formulate anew their strategies. The history of Ryanair began in 1985, when the company launched the first short daily route from Waterford in the Ireland to London Gatwick, pioneering the low-fares flight’s operating model in Europe. Thanks to a number of reasonable strategic decisions and changes provided by the company’s executives, the Ryanair have managed to strengthen market position enormously. Today Ryanair Limited is the largest and top-ranked low cost (or no-frills) airline company at the European passenger airline market. It serves low-fares, point-to-point routes from the so called â€Å"Ryanair’s bases of operations† consisting of about 40 airports in Ireland, the UK, Continental Europe and Morocco (RAa, p. 53).
