Annoyances of my life Essay

Through my life, I can say for many reasons it is annoy. The main reasons that causes my life annoys are the following: Being a minor, the transportation, language and pressure. I have to handle all of them every day; I do have a plan to keep going and almost all of them are not permanent. First, to be 17 years old is not easy. It is a challenge for me, because I am independent but not old enough to be free. I have to ask for permission to do everything, also there is a problem to find a job. I remember when I was 16 years old I broke my finger. The doctor did not want to see me because I am minor. A lot of disadvantages are caused by my age. Transportation is one of the biggest annoyances in my life. I have to leave home more than a hour to be on time for class, If I own a car that could be about 15 minutes. I hate when the bus is more than 2 minutes late because that makes me miss the trolley. English is not my first language; It is annoy when I cannot understand anything. I do not like to have to read my books so many times to make sure I understood the lecture. It is annoy when people laugh because of my pronunciation or any spelling mistake. Learn another language is interesting but sometimes it makes me frustrate. I am a kind of person who does not feel well under pressure. My family are first to ask for more than what I can do. It makes me mad because I always do the best I can. Especially in college the pressure is greater, a lot of classes and homework. Sometimes I am scare about not pass my classes, it does not let me sleep. Pressure is super annoyed for me. In conclusion, there are several things that make my life annoy. Almost all of them have a way to be solved. I will turn 18; I will get a license and be able to drive a car. College is not forever and is for a better life, my mom and brothers will be proud of me when I done my career. Thinking positive makes me see the annoyances of my life in the good way. It is great to know I am doing my best to reach my goals.

Gelatin: Colloid and Conductivity Essay

In recent years there has been a revival of interest in the micellar theory of structure proposed by N~tgeli in 1852 as a theory for the structure of protoplasm. This theory has been taken over by colloid chemists and applied to the structure of many colloids as a result of the work of Zsigmondy (1), Pauli (2), McBaln (3, 4) and their co- workers. Laing and McBain (4) have further extended the micellar theory to the sol-gel transformation by proposing that the micellar unit of the gel state is identical with that in the sol. According to these authors: â€Å"All that is necessary is to assume that the particles become stuck together or oriented into loose aggregates, which may be chance granules or, more probably threads. † This conception is based on a study of sodium oleate, for which they found that in spite of the enormous change in viscosity involved in the change from sol to gel, such properties as electrical conductivity, lowering of the vapor pressure, refractive index, and sodium ion concentration remained identical in both the sol and the gel state. In support of their theory, Laing and McBain point out that Arrhenius (5) found the conductivity in gelatin-water-salt systems to be the same in both sol and gel. This aspect of the micellar theory has been extended by Gelfan (6) to protoplasm because he found that the conductivity of protoplasm remained independent of changes in viscosity and by Gelfan and Quigley (7) to the blood coagulation process since their experiments showed that during the coagulation process there is no change in the conductivity of shed whole blood or plasma, in spite of the almost infinite increase in viscosity during coagulation. In view of the concentration of excess electrolytes in the gelatin experiments of Arrhenius, as well as in protoplasm and in blood, the question arises whether the generalization from the findings on sodium oleate to all gelling systems, particularly among the proteins, is valid. In other words, is the identity of conductivity in the sol and gel state due to an identical micellar structure of these protein sys- tems, or is it due to the conductivity of the excess electrolytes being so much greater than the conductivity of the ionized protein salts that the difference in conductivity produced by the structural changes involved in the sol-gel transformation was not detectable by the experimental procedure employed? That there is little or no change in the conductivity and diffusibility of lectrolytes in colloidal systems on changing from sol to gel has long been known and is not a vital point in connection with the micellar theory of Lalng and McBain, since all theories of gel structure postulate that the structure pro- duced is enormous in size compared with ionic dimensions and thus exerts almost no hindering effect on ionic movement. To obtain a fuller insight into the question, the following study has been carried out on the conductivity of gelatin sols and gels. Gelatin was selected because it is an example of a protein capable of undergoing a reversible sol-gel transformation. In carrying out the study we had in mind the work of Krishnamurti (8) who, from a study of the light-scattering in sols and gels of agar, has concluded that the micellar structures in the two states are not identical; and also that of Craig and Schmidt (9) who found differences between the refractive indices of gelatin sols and gels. Experimental Procedure In measuring the conductivity, the Kohlrausch principle was employed, with the difference that a one-stage vacuum tube amplifier was introduced between the bridge and the telephone, which made it readily possible to make measure- ments accurate to 0. per cent. The source of the bridge current was a General Radio Oscillator, and the capacity of the conducting cell was balanced in parallel by the setting of an adjustable condensor. The conductivity cell used through- out the experiments was of the bottle type, constructed of Pyrex glass. A ther- mometer, readable to 0. 1 A °, was fitted into the neck of the ceil in such a way that it could be immersed in the gelatin without interfering with the continuity of the liquid betweeen the electrodes. All measurements were made at 25A °C. â€Å"Difco† granular gelatin was used in the experiments. It was purified and made ash-free according to the procedure described by Loeb (10). The purified gelatin on analysis was found to be totally ash-free and in aqueous solutions to have a pH value of 4. 75 as measured by the hydrogen electrode. The analysis of the gelatin in the experimental solutions was carried out by evaporating l0 cc. portions to dryness in porcelain crucibles and then heating at 110A °C. to constant weight. The plan of the experiments was to warm the gelatin to a temperature of about 37* to obtain the sol, fill the conductivity cell with he liquid gelatin, and then immerse the filled ceil in an oil thermostat kept at 25*. The leads of the con- ductivity bridge were connected with the ceil and when the temperature of the gelatin fell to 25 A ° as shown by the thermometer immersed in the gelatin, the con- ductivity reading was first taken, and then further readings were made at various time intervals. To check the conductivity readings, the gelatin in the cell w as again warmed up to 37 A ° and the procedure repeated. To obtain the conductivity of the gel, the cell filled with gelatin was cooled down in an ice chest to about 10 A ° to obtain a firm gel. The conductivity cell was then returned to the 25 A ° bath and the conductivity reading taken when the gel reached the 25A °temperature. As with the sol, the readings for the gel were checked by repeating the cooling. The experiments carried out were first, a series at different concen- trations of the pure isoelectric gelatin itself to determine the effect of variation in the concentration of gelatin. The results of this series are given in Table I. In this series, it was found that all concentrations of gelatin above 1 per cent set to a firm gel at 25 A °, but that concen- trations of 1 per cent or less remained in a semiliquid state at this temperature. From the results on the pure gelatin, a concentration of gelatin was selected that would set to a firm gel at the temperature of the conductivity measurements, namely, about 3 per cent, and experiments were next carried out on the effects of electrolytes on the conductivity of the sol-gel transformation. The electrolytes used were hydrochloric acid, sodium hydroxide, and sodium chloride at varying concentrations. The results of these experiments are re- corded in Table II where there are recorded the gelatin content, the concentration of electrolyte added, the conductivity of sol and gel respectively, and the percentage difference of conductivity between the two states. In the measurement of the conductivity of the gelatin sols and gels it was found, except for those samples where there was no difference in conductivity between sol and gel, that the conductivity did not attain a constant value as soon as the 25 A ° temperature was attained, but on the contrary, continued to drift slowly even though the temperature remained unchanged thereafter. This drift was in the direction of a decreasing conductivity for the sol and an increasing conductivity for the gel, which on being allowed sufficient time, starting from either The lack of correspondence to a small degree between the gelatin concentration and the conductivity in certain of the experiments listed is explained by the drift in the conductivity noted in the text which makes an exact reproducibility in gelatin solutions impossible. the sol or gel state, finally reached a constant value representative of the equilibrium state of the gelatin at that temperature. In the present experiments, this equilibrium state for all except the 0. 9 percent gelatin of Table I was a firm gel. In the experiments where no difference in conductivity was found between the sol and gel condition, this drift was absent and in these samples when the thermostat tem-perature was once attained, the conductivity became constant. This was the result found for the first experiment of Table I, with a con- centration of 0. 90 per cent gelatin for which a semiliquid state was the state at 25 A ° and for the experiments of Table II where the con- ductivity difference between sol and gel was zero although firm gels were stable at the 25 A ° temperature. The conductivity figures for the rest of the experiments in Tables I and II are the values measured just after the thermostat temperature was attained by the gelatin. The data with the pure gelatin and the electrolyte-containing gelatin solutions are not in accord with McBain’s theory. Rather they are in harmony with the viewpoint that there is a distinct difference in the micellar units of the sol and gel state when a definite firm gel is formed. The gel state shows the lower conductivity of the two forms, which would be expected if the micellar unit of the gel is composed of aggre- gates of the sol micelles, thus naturally resulting in a lower electrical mobility. That the difference in conductivity is due mainly to electrical changes accompanying the structural changes of the sol-gel transformation is indicated by the experiments of Table I. Since in these experiments, the gelatin was completely ash-free, the measured conductivity can only be a measure of the electrical charge of the gelatin in the solution and the accompanying hydrogen ions. From the pH value of 4. 75 given by these solutions, the hydrogen ion concentration is less than 2 A— 10 -5 tools per liter, which, using the value of 350 for the hydrogen ion mobility, leads to the value of 0. 7 A— 10 -5 for the specific conductivity. This value in comparison with the values found for the gelatin, points to the conductivity coming mainly from the charged gelatin and that the decrease in conductivity on gelation is due to aggregation of the gelatin units. The data of Table II substantiate this point of view. When the electrolyte concentration is low there is a distinct difference between the conductivity of the sol and gel state. This difference decreases with increase in the electrolyte concentration and is no longer detected when the conductivity of the electrolyte-containing solutions increases about 100-fold the value of the difference in the conductivity between the sol and gel of the original isoelectric gelatin. The conductivity difference between the gelatin sols and gels as shown in Table II becomes undetectable at an electrolyte concentration of approximately 0. 01 molal, yet blood and protoplasm contain more than tenfold this amount. On this account, the experiments on the electrolyte-containing gelatin solutions throw grave doubts on the conclusion drawn by Gelfan for protoplasm and by Gelfan and Quigley for the blood coagulation process. In view of the large excess of free electrolytes in the systems studied by the above authors, the fact that they found no change in conductivity with changes in viscosity or on gelation, is, under the circumstances, no proof of either an identity of micellar structure in the different physical states of the systems they studied or of a micellar structure at all. From the present studies, along with Craig and Schmidt’s refractometric results, and the work of Krishnamurti on agar, it must be con- cluded that the McBain theory of an identical unit structure for the sol-gel state has no general applicability.

Professional development - Coursework Example The key trends in the specialty of occupational health nurses include electronic records to integrate primary care and occupational health. This is the biggest change that is happening to the health care reforms particularly for the occupational health nurses. Use of electronic records will ensure employees are treated for personal medical issues by use of on-site clinic (American Association of Occupational Health Nurses). There is need for resources and for the relevant management to acknowledge the significance of occupational medicine or occupational health. The managers need to understand the cases and why we insist on occupational health on a daily basis. Most people who are outside the field have no knowledge what the occupational nurses do. Another trend that I notice in the American association of occupational hazard nurses is increase in OSHA surveillance and more awareness concerning environmental hazards and their impacts (American Association of Occupational Health Nurses). Environmental health is the main aspect of occupational medicine. Most nurses are starting to recognize the need for patient advocacy. Patients are helped by the occupational health nurses to navigate through surgeries since they are sort of case managers. The occupational health nurses carry out activities that determine whether a section of workers is suffering from an occupational illness because of exposure to certain hazards. Currently, employees are exposed to human blood, animals and other body fluids, viruses and bacteria. By increased health surveillance, more employees who have been exposed to infectious biological agents have gone through immunization. Health surveillance operates on the basis on environmental assessment, and the exposures are evaluated and documented. Health promotion and protection is yet another trend within the occupational health nurses. The nurses are aware that they are responsible for health

Multinational Business in the Chinese Economy Research Paper - 1

Multinational Business in the Chinese Economy - Research Paper Example The persistence poverty level, especially in Northern Shaanxi and other parts of China, is due to economic disparities. The income disparity has been the key issues in China; thus, here is the need to widen the geographical income gaps, avoid industrial clusters and improve infrastructures, which are barriers to economic growth in the interior geographical locations of China. Dimensions of Distance The distance matters for multinational business because of varied issues. First, the cultural distance is one of the matters for successful business performance and economic growth of China. Differences in language are one of the cultural issues impacting the economic and geographical locations of the multinational companies. The language barrier is still a problem for companies carrying out business activities overseas. This is because the Chinese have their language, which they use in the country, and it is difficult for foreigners to understand. Moreover, different ethnicities and poor social network communication are attributes of cultural distance. Lack of effective and well-developed social networks may hinder the successful business performance of multinational companies. China has many industries, some of which are multinational companies located within the economy. However, due to poor infrastructure development, especially roads and the communication network, many of them are unable to meet their demanding goals because of lack of connective ethnic or social networks. Ghemawat argues that an economy’s cultural attributes such as ethnicity, social norms, different languages or national identity on consumer products matter a lot in business activities.  This is because religious beliefs, ethnicity, language or social norms are capable of creating distance between two economies (Ghemawat 140). Secondly, the administration distance is another matter for multinational business. Historical and political organizations being shared by more than one country may create an impact on multinational business. Ghemawat points out that government policies, political hostility, lack of shared or political connections and institution weakness are among the attributes creating administrative distance (140). These attributes may impact the effective business performance of multinational companies. China is one of the emerging economies that have made efforts to improve the economic growth. However, an administrative distance is still a matter towards becoming a fully developed nation. For instance, individual government policies including environmental, trade and other policies create a barrier for successful multinational business. Thirdly, geographical distances matter for multinational business. This is through creating barriers towards successful business performance because of increased transportation costs, bulk ratio issues and losses encountered in the transportation of fragile or perishable commodities in a long distance. Geographical d istance is not a matter of how far is the place in terms of miles or kilometers – other attributes contribute to geographical distance. These include the physical scene of the nation, topography, access to waterways as well as transportation and communication infrastructures. These are among the attributes that have impacted the effective business performance of the multinational business in the Chinese economy.

Examine an interaction or event from your clinical placement, which Essay - 1

Examine an interaction or event from your clinical placement, which has required you to demonstrate professional conduct (NMC 2008) - Essay Example The author employed a variation of the Thornwaite-type technique, as well as correlated AET and Deficit supported by tree species distribution. The data used is primary because it was collected and analyzed by the authors, and not mined from some other sources. Temporal analysis is used on a moderate scale, and the analytical method used is plots (Lutz, Wagtendonk, & Franklin, 2010). The author uses plots to analyze the data and to represent the data sets. The author plots the data sets as graphs depicting the correlation between multiple sets of data. The authors computed species climatic envelopes in wide ranges of climatic gradients. They also distinguished tree species using Deficit and AET. For all species, modeled Deficits grew by an average of 5% from past and present, while forecasted growth in Deficit from present and future were found to be 23% in all plots (Lutz, Wagtendonk & Franklin, 2010). The authors have answered the hypothesis by providing sound analyses and evidence to meet the aims (Lutz, Wagtendonk & Franklin, 2010). The authors also discuss further studies in the areas of topographic scale distributions of aquatic balance, potential impacts of climate change situations, the scale of vegetation change, sensitivity of plant and animal species, and the downscaling problem (Lutz, Wagtendonk & Franklin, 2010). What I find most interesting is the analyses conducted on AET and

Global warming by human caused Essay Example | Topics and Well Written Essays - 2000 words

Global warming by human caused - Essay Example In addition to this, several non-human activities, such as variation in the orbit of earth around the sun, rapid changes in atmospheric composition, volcanic eruptions and solar luminosity are also responsible for the global climate change. Global climate change has become one of the most challenging and critical issue that is affecting ecological and environmental balance of the globe. It is difficult to justify the major responsible reasons behind this global warming. Several scientists have argued that human beings’ unethical activities are responsible for this issue. On the other hand, some of the scientists around the globe are trying to illustrate that volatile change in natural and environmental structure is causing rapid global climate change. The essay will provide an argument on the topic i.e. â€Å"Can the humans be held responsible for global warming?† Major Reasons behind Global Warming There are several reasons behind the climate and temperature change in the earth’s surface. The part of the essay will provide an argument about the real causes behind the global warming and rapid global; climate change. Non-Human Reasons The temperature of the earth depends upon the balance between the planet’s system and energy entering. When the energy from sun is absorbed, earth warms. On the other hand, when the energy of the sun is reflected back then the earth generally avoids warming. There are several non-human reasons that are affecting the global temperature. Green house effects, variation in the energy of sun and change in earth’s surface as well as atmospheric reflectivity are the factors responsible for global warming. Several scientists pieced a picture of the climate, dating back thousands of years through the analysis of various indirect measures like tree rings, glacier lengths, ice cores, and ocean sediments, changes in the orbit of earth and pollen remains. The valuable historical record shows that the global cl imate system varies naturally (Lawson 22). The output of the sun shows narrow variations over the course of a particular 11 year time cycle. These cyclic changes effectively correlate with the frequency and number of sun spot. It is known as solar cycle. This solar spot is growing slowly and gradually. However, the rapid increase of solar spot is affecting global climate. The climate is getting hotter and hotter due to this reason. On the other hand, position of the earth with respect to the sun slightly varied over a longer period of time due to the change in orbit of earth. However, this frequent change is termed as Milankovitch cycle (Shrivastava 109). According to the view of several scientists, these changes are major culprits for the global climate change since the Ice Age of earth. These changes have limited impact on the global temperature and climate change for a shorter time cycle. These changes have occurred slowly and gradually. This Milankovitch change has impacted the global climate and earth surface’s temperature. It has resulted in long-term climate and temperature fluctuations. Water vapor is considered as the most abundant green house gas in the atmosphere of earth although the changes in the water vapor’s concentration are generally the result of temperature changes. Consequently, this water vapor can significantly act as the part of feedback loop (Arnold 272). In the feedback loop, the increase in temperature typically triggers an effective increase in the evaporation of the water. The

Sustainable Architecture Essay Example | Topics and Well Written Essays - 1000 words

Sustainable Architecture - Essay Example Engineered structural materials is defined as "recycled/reconstituted wood materials that employ laminated wood chips or strands and finger jointing (the gluing of larger pieces together)" (Sustainable Building Sourcebook, 2006). The materials that formulate the structured materials fall under the category of engineered wood and as such it means that the "tolerances in stability, consistency, straightness and strength are more precise then dimensional lumber, making the products easier to work with. In joist and rafter applications, the reconstituted products are particularly useful for long spans without bowing or lateral movement" (Sustainable Building Sourcebook, 2006). When making these building materials look to drastically minimise the amount of waste that is created in processing the raw materials as waste wood and entire trees, regardless of their size, age or species can be utilised in making these products. "Finger jointed studs reduce waste in two ways. Short pieces that normally would be unusable are combined rather than disposed and the engineered quality of finger jointed materials eliminate warping or cracking. The strength of the joints in good quality material is such that the solid wood portions will be more likely to break than the adhered finger joint" (Sustainable Building Sourcebook, 2006). The following graph outline both satisfactory and unsatisfactory or difficult in various circumstances of recycled/reconstituted wood and explain the ease of both finding satisfactory results in finding the technology and costs relatively low. There is also the issue of both finding the financing in engaging in implementing the recycled/ reconstituted wood along with much more public acceptance as the public continues to be interested in companies that engage in sustainable material practices. Figure 1 Commercial Status Implementation Issues Recycled/Reconstituted Wood Legend Satisfactory Satisfactory in most conditions Satisfactory in Limited Conditions Unsatisfactory or Difficult When looking toward sustainable materials in the construction industry it is important to start with forestry management. There are many companies that look toward accomplishing sustainable building product development by first looking toward how to better utilise the forest itself. Hunt and Winandy (2002) write about how 3D engineered fibreboard as "an economically viable process to produce three-dimensional structural fibreboard products that can utilise a wide range of lignocellulosic fibres contained in the forest undergrowth and in underutilised timber. This will encourage the public and private sector to undertake thinning or clearing of these components from the forest thereby reducing or removing dangerous fuels and minimising costs to the federal government for fire mitigation" (106). Hunt and Winandy's (2002) proposed product "consists of a structural material which can be made from a wide range of little or no-value

Case Review and Principles Governing Application of Privacy Related Essay

Case Review and Principles Governing Application of Privacy Related Torts - Essay Example In the previous history of the case, the plaintiff, Wentworth, lodged an amendment complaint against Settlement Funding, the defendants asserting that the defendant took part in actions that amounted to copyright violation, trademark dilution, injury to the business reputation and false representation in breach of sections 32 (1) and 43 (a) of the Lanham Act, 15 U.S.C pursuant to section 114 (1) and 1125 (a) (2006) (O’Neill 1). The plaintiff also claimed trademark violation and unfair competition under Pennsylvanian state law. The plaintiff claims originate from the defendant’s supposed use of plaintiff’s emblems in two ways: through Google’s Adwords program and the â€Å"meta-tags† for defendant’s webpage (O’Neill 2). The plaintiff alleged that the two usages of the plaintiff’s brand name guarantees that a link to defendant’s webpage will appear instantly adjacent to a link to defendant’s webpage when people carry out internet searches for â€Å"J.G. Wentworth† or â€Å"JG Wentworth† (O’Neill 4). The plaintiff further claimed that the use of the plaintiff’s emblems constitute violating deeds that were aimed at confusing the consumers and to divert prospective customers away from the plaintiff’s webpage (O’Neill 6). Plaintiff noted that this also would steal their potential customers and wear down the uniqueness of plaintiff’s emblems, therefore, resulting to a considerable loss of profits. In its judgment, the court granted the defendants the motion to dismiss and, therefore, the plaintiff’s claims were dismissed (O’Neill 8). ... In the previous history of the case, the plaintiff had moved to court and lodged claims against trademark violation and false advertisement. The plaintiff relied on sections 32 (1) and 43 (a) of the Lanham Act. The plaintiff claims originate from the defendant’s supposed use of plaintiff’s emblems next to the defendant’s name in the search results. The plaintiff noted that the appearance of the trademark next to the defendant’s name could indicate a relationship with the defendant. In the first circuit, the court had discharged charges on trademark violation relating to material on the defendant’s webpages since none of the rings were branded â€Å"dating rings†, the trademark of the plaintiff. However, the court permitted trademark violation linking to purchase to survive and dismissed the false advertisement claim. In the second circuit, the court established that this type of entry of the search results next to the plaintiff’s emble m included a â€Å"use† under the Lanham Act. In the case J.G Wentworth, S.S.C. Limited Partnership vs. Settlement Funding LLC, in order to determine breaches of section 32(1) and 43(a) of the Lanham Act, the court, as according to Fisons Horticulture, Inc. vs. Vigoro Indus, Inc., 30F.3d 466, 472 (1994), required the plaintiff to demonstrate that the plaintiff’s emblem is lawful and protected by law, that the plaintiff is the rightful owner of the mark and that the defendant’s use of the emblem to recognize goods or services was most probable to generate confusion regarding the origin of the goods (O’Neill 5). Additionally, as according to the claims of the defendants, the plaintiff would not meet the third aspect of the Lanham Act on trademark

To Think or Not To Think, That is The Question Essay Example for Free

To Think or Not To Think, That is The Question Essay â€Å"Judgment matters: it is what separates winners from losers† (260). Blink by Malcolm Gladwell is a book about understanding how we arrive at the judgments we make. There are two ways that we make every decision: in the blink of an eye or with well thought out decision making processes. In this book Gladwell explores the many different ways that we make decisions using our adaptive unconscious. He attempts to convince the reader that snap decisions can be just as good as ones we ponder upon. In all aspects of our life we are continuously making decisions. Often times we go with our instincts. An instinct is something that is created by a collage of past experiences and the knowledge we have gained from them. The unconscious can make better decisions than the conscious at times. Have you ever had a â€Å"gut reaction† to something and then thought about it for a while and changed your mind? Frequently thinking is the wrong thing to do and the instinctive decision was the best one. Teaching us how the mind works during decision making is Gladwell’s main goal. From there it is up to us. The book begins with the story of the Getty Museum in California and the fourteen month process involved in their purchase of a Greek kuoros. The museum hired lawyers, geologists and researched the basics on what the style of a Greek kuoros would be. Eventually they were satisfied with all the information they had gathered and they purchased the statue. There was a big problem though. Numerous art experts looked at the kuoros and within seconds had a bad feeling about it. Their instincts were telling them that the statue was a fake. After much debate, the museum resigned itself to listing the kuoros in their catalog with the words â€Å"About 530BC, or modern forgery† (8). One way to hone our instincts is using something called thin-slicing. This is the process where you slow down what is happening. You take thin slices of time and use the pieces of knowledge you gain from that slice to make your decision. Gladwell draws on multiple studies and experiments to explain this. The study that is the most prevalent and mentioned throughout the book was what would become The Mathematics of Divorce by John Gottman. In this study Gottman videotaped couples engaging in a discussion about a contentious topic in their marriage. There were multiple sensors monitoring the couple’s physical changes, such as heart rate and movement. He found that by breaking down the videotaped interaction into fractions of a second and applying the information to a mathematical chart he was able to predict divorce rates among the couples. After watching just an hour of video tape per couple, Gottman is able to predict the divorce rate in the span of fifteen years with ninety-f ive percent accuracy. The next section of the book explains what defines a snap decision. When you experience something there is a feeling of knowing. You can’t explain how you know, you just know. He gives the example of tennis coach Vic Braden. Braden is able to predict when a tennis player is going to double-fault on his serve before the player had even released the ball from his hand. Braden was searching for an answer as to why he was able to do this and he couldn’t find one. It was a snap judgment, an instinct and something that cannot be explained. Instincts can also lead you astray. Gladwell’s chapter about Warren Harding explains how the former president rose up through the political ranks based solely on his appearance and the way he spoke. He was not a terribly impressive man intellectually, but voters went with their first impression of him. He won because he was the most handsome and eloquent candidate, not because he was the best. Our first impressions are not 100% reliable. We all have associations between certain things that are ingrained in our unconscious minds and we’re not even aware of them. There are stereotypes inside everyone, even when we consciously think there are not. Gladwell explains that â€Å"unconscious  attitudes are not compatible with values† (85). Our experiences create our first impressions, including those experiences that are negative. As I stated earlier, associations become ingrained in our unconscious minds even if we’re not aware of them on a conscious level. That is a case where a snap decision would be one made without having enough information. The opposite can be true as well. Sometimes we have too much information. Gladwell tells the story of heart attack diagnoses at the Cook County Hospital in Chicago. The doctors were running many tests and gathering too much information to accurately separate patients of different heart attack probabilities. The hospital reformed the way they analyzed heart attack patients by talking extensively with them along with doing some minimal testing. Using this new system proved to be more effective than when they were amassing a large amount of data. The author states that â€Å"truly successful decision making relies on a balance between deliberate and instinctive thinking† (141). Gladwell goes on to cite a study by Jonathan Schooler and Timothy Wilson regarding people’s preference in jam. Random shoppers at the grocery story were asked to sample several types of jam and rank them in order based on which was the best. When asked to explain why they made the choices they did many of the shoppers changed the order in which they’d ranked the jams. Why? Because when you have to explain an instinctive decision it’s difficult to put into words. This can lead people to change their choice to one that can be explained. One snap decision that was difficult to explain involved the shooting of Amadou Diallo, and unarmed man, by four police officers. They spotted Diallo in a dark entry way in a bad part of town late at night. When they spoke to him, he did not comply with their orders and began pulling something from his pocket. The situation was unfolding quickly. The officers didn’t take time to thin slice what was happening, to read Diallo’s mind. They assumed he was reaching for a gun, so they shot him. In truth he’d only been reaching for his wallet. Events need to be slowed down and thin sliced in order to listen to what instinct is telling us. We need to  pay attention to what is occurring in fractions of seconds, not in minutes. Gladwell states, â€Å"Every moment – every blink – is composed of a series of discrete moving parts, and every one of those parts offers an opportunity for intervention, for reform and for correction† (241). In the end, it is up to each of us to explore our adaptive unconscious and discover the pieces that make up our snap decisions. Gladwell clearly states his opinion, â€Å"The best we can do, I think, is try to puzzle out the right mix of conscious and unconscious analysis on a case-by-case basis† (269). We need to know what goes on inside our minds so that we can make solid judgments and know when to think and when to react without thinking. This book opened my eyes to many things. I found the studies fascinating and informative. The theory of thin-slicing is definitely something I’m going to try to use in my daily life, slowing things down and really paying attention. I believe there is a lot to be learned about what guides my choices and molds my snap judgments. This book is very relevant to the world of work. Business today moves faster than ever before. Information shoots back and forth at lightning speeds thanks to the progress that’s been made in communications technology. It’s vital that business people know how to read their own minds and are aware of some of the biases that may be involved in instinctual judgments that they make. There are so many times in business when you need to make urgent decisions and don’t have the luxury of time to contemplate. Another area where this book’s insight would be valuable is human resources/hiring. The sections on hidden prejudices serve as an invaluable reminder that we may have firm beliefs, but there are stereotypes hidden within our unconscious mind. It is good practice to be aware that how you are behaving, your body language, will affect how the potential employee will behave during an interview. Even if what is being said is benign, our faces show everything. Gladwell words it perfectly: â€Å"The face is not a secondary billboard for our internal feelings. It is an equal partner in the emotional process† (208). The quote at the beginning of this paper shows the attitude we must take when dealing with business in the twenty-first century. You have to possess the ability to make solid judgments in minimal time. Business decisions made now have an extremely large impact on society as a whole, directing the world down whatever path it goes. If the decision makers are able to look inside and see what makes them tick they will make better choices. Business today has a social responsibility, just as every person has a social responsibility. Gladwell leaves us by clearly defining the weight that is on our shoulders, â€Å"It is not enough simply to explore the hidden recesses of our unconscious. Once we know about how the mind works – and about the strengths and weaknesses of human judgment – it is our responsibility to act† (276). So one last time I quote this author, â€Å"Judgment matters: it is what separates winners from losers† (260). Works Cited Gladwell, Malcolm. Blink: The Power of Thinking Without Thinking. 2005.

Implementation Of The BIM Technology Information Technology Essay

Implementation Of The BIM Technology Information Technology Essay Around the globe, designers have started using the new technology known as BIM which is still to be used by their Indian counterparts. Their reluctance to use this technology has held them back in aspects like walkthroughs and visualizations (Autodesk, 2005). There could be two factors for the lack of use of this technology. This technology is not known by the designers or the users of the Indian AEC industry lack the skills required to use this technology. BIM services are being outsourced by the Indian development centers to places like UK, U.S and the countries in Europe in order to avoid any delays, clashes on site, cost overruns etc. The Indian talent is being made use of by the AEC firms situated in U.K, U.S and the European countries. They are getting various advantages like the talent of Indian developers and low cost production (PRLog, 2007). Complex designs and projects are being built by Indian architects. There are requirements is aspects like integration and information technology, development, simulation, communication, coordination and knowledge sharing. At present, there is no standard consistency regarding the use of the BIM technology and the process of its implementation. This lack of uniformity has been acknowledged even by the Associated General Contractors of America. A lot of software firms have tried to get the best of BIM by developing programs pertaining to several parts of the BIM although none so far have looked at it as a transformation process. This is one of the reasons that we need to build a standard and make the implementation of the BIM technology on the global scale. Significance Architecture is a well to do field in India with a vast client base (Autodesk, 2005). The systems are according to the global standards which are managed by well trained staff of skilled people. There has been rapid modernization in the form of malls, IT parks, and residential complexes in India which has led to the demand of architects. India is still a developing country and is short on infrastructure in almost every sector (Autodesk, 2005). Construction and planning is taking place in full force at present. The low wages of worker has been a factor in using alternate automated solutions. The advantage of BIM however is found in savings and better system than the competitors. The time of turnaround is less which is a huge factor to gain a competitive edge. Firms in architecture should use this technology and stay ahead with the times by keeping in sync with the technology and engineering aspect of architecture. The design of a building should follow a non deterministic method rathe r than forming a closed opinion from the start. New architectural experiments can be performed with the help of this approach to achieve tectonic perfection. Purpose The use of BIM systems in combination with simulation and analytical tools helps in building of a prototype of the building, gain information related to activities of construction and performance even before breaking ground. High value is associated with such a prototype. BIM is useful in such situations as it encourages designers to improve the quality and efficiency by avoiding less than effective practices and making use of the best available techniques. It is necessary for BIM to create a digital model which can be used to ascertain schedule, quality take offs and estimates to lessen the effort and time spent on it. This is required to achieve the optimum benefit of BIM. The project purpose is to find the difficulties in front of Indian architects with regards to the use of BIM while being aware of the principles of the Indian AEC industry to create a strategy for implementation of BIM technology. Building Information Modeling or BIM is a process of documentation which gives information related to the various phases of a project like planning, construction, design, operation and facility management. It is a documentation process providing details of construction application and operational visualization, design coordination and scheduling. The main benefit of using BIM is the aspect of visual coordination used in building systems such as MEP (Mechanical, Electrical, Plumbing). It is also useful in the identification of difficulties that can be taken care of before the construction of building resulting in savings in terms of time and money (Damian, Han Yan and Peter (1)). In a report by the National Institute of Standards and Technology, it was reported (NIST, 2004 (2)) regarding the lack of necessary interoperability that burdens the U.S facilities by around 15.8 billion dollars every year. The BIM technology application has thus far not been used in India but has the chance to use it on a large scale. Introduction Architectural Documentation of Structures BIM has enabled maturity of the Architectural Documentation. A properly maintained documentation using a system can be dated back to the Renaissance in the presentation of the plans for Santa Maria del Fiore by Fillippo Brunelleschi in Italy. The patron was made to understand the design of the building by means of drawings. Architectural Documentation has become more modern in its usage over the years. A data model can be created from the design process to the conceptual and operational phase with the computer aided software. A summary of the evolution of the Architectural Documentation ahs been mentioned in the following text. First phase- Early 1980s: The design documents before the year 1980 were made with the help of lines that would represent the building. The documents would be of the pattern of plan, elevation and section that acted as the base to show the picture of the building to be created. Second phase- At the start of the twenty first century: Building that are constructed nowadays are complex in nature than ever before. The drawings of the building are worked upon by a large number of people. There is a phenomenal increase in the number of buildings which can be owed to the technological advances. Buildings are constructed keeping in mind HVAC (Heating, Ventilation, Air Conditioning) and energy necessities. Computer technology helps in greatly reducing errors but one has to remember that the collections in the end are created manually in the form of text and lines. BIM Concept There is a change in the expectation and process taking place in the Indian construction field in lieu of the economic ups and downs and the architects have stepped up to the plate. There has been a change in the working of the more common 2D based practice related to economic, functional and energy. A single database can be used to share the disciplines in a project. Structure, architecture, electrical, mechanical, construction ad infrastructures are bind together and the coordination between all these factors is a tough task. Energy analysis can take place along with the design phase. The costs of construction have become predictable. With BIM, it is possible to use a parametric 3D model to generate automatically building documents like sections, plans, details, elevations and schedule. BIM supported software produces drawings that are in correlation with representation of the model. If there are any changes made in the project, they are coordinated in the rest of the project autom atically. This is a big advantage as there is lesser risk of coordination issues and helps in improving the quality of work on the whole. Various modeling software packages are known that can be used in the application of conceptual level models although they do not possess the capability of documenting a design for construction of a building. CAD and BIM The basic difference in Computer Aided Design or CAD and BIM is that CAD is a 2D document that is created separately and does not relate in any way to the other documents created separately. A wall is represented by two lines in CAD. A wall is created as an interactive tool in BIM that has its specifications like height, width, bearing and nonbearing principle, interior or exterior, fire rating, demolished or new and materials such as bricks and boards. All the information is assembled by the BIM platform into one single location and then goes on to cross link the data among its related objects. Linkage is not seen between the data that is developed by CAD. Comparative efficiency between BIM and CAD is seen in Table 1. In case of BIM, there are three types of information which is related to the model. Object based geometry- For instance; in BIM a window is an object with qualities similar to a real window rather than just being a collection of lines, points and surfaces. The wall receives a window when the window is placed in the wall by means of adjusting the geometry to fit the placement of the window. The wall allows the window o be placed in locations that are pre defined by the parameters that have been programmed for it. Parametric integrity is yet another feature of BIM geometry which relates to the connection between elements which are maintained consistently even when the model is being manipulated. For instance, suppose a window was programmed to a distance of four feet from a door and there is movement in the position of the window then the window automatically moves itself in order to maintain the distance of four feet from the door. The second form of information related to the BIM model is the non graphical information. It defines the structure and function of the model and any properties that are related to it like fire rating, cost, reflectivity, materials content and conductivity. There is a big list of these properties which is limited only by the information that is required the computation power required to process it. Linked information is the third form of information which is associated but not contained in the model directly. Gantt charts and fabricatorà ¢Ã¢â€š ¬Ã¢â€ž ¢s shop drawings used in scheduling and construction are two such examples of this form of information. A common incorrect assumption is that CAD relates to 2D design whereas BIM relates to 3D design. CAD technology can also be used for 3D designs. The main concern for any BIM service is whether the model that has been created is computable or not. Information regarding the model can be easily understood according too the modelà ¢Ã¢â€š ¬Ã¢â€ž ¢s purpose if the model is computable. For example, a 3D model wall that looks good will not be understood by the computer as a wall. The wall cannot insert a window in it and cannot be viewed as a wall created by raw materials. Another aspect of BIM is the Virtual Design and Construction or VDC. According to CIFE, VDC is defined as the use of multidisciplinary performance models of design construction projects. CIFE acknowledges BIM as a tool useful to support product design that is a part of VDC which highlights the organization, product and design construction operation team processes. It is said by some that BIM is more than design software and can be viewed as a module that involves the whole project team. Irrespective of the definition of BIM, the success in implementation of VDC or BIM lies in the coordination throughout all the project teams which is talked about in later parts of the paper. 1.2 Big BIM vendors There are many high roller vendors in the BIM technology market. REVIT is the creation of Autodesk that is directed towards the collection of all the building elements in a single database which helps in providing the users to see results of design modification quickly and enable them to identify interference issues. Bentley Systems makes use of another approach that produces a family of the application modules that relate to each other easily. The modules include Bentley Structural, Bentley architecture, Bentley Building Electrical Systems and Bentley Building Mechanical Systems. Graphisoft is another big name that was purchased by a German firm by the name of Nemetschek in the year 2006. The approach of their BIM is to make a virtual building model to support their main product ArchiCAD that would associate itself with other applications. At last, there is CATIA which was developed by Dassault Systemes that was created for the aerospace industry. It has been adapted by Gehry Technologies to use it in the AEC industry. 1.3 Contribution Building owners and developers lay the most emphasis on information modeling as said by publications related to BIM. A definitive framework to show the value in the life cycle of the creation of the building is missing. For instance, The Contractors Guide to BIM which is established by The Associated General Contractors of America is an informative and precise document with the focus being on BIM from the point of view of a contractor. Similarly, publications floated by fabrication or design related organizations show the perspective of their companies. It is clear from the above two statements that the content of the information on BIM is in favor of the organization who writes it which is more often than This paper is from the point of view of developers and owners who are the most important factor in the construction industry as these entities are responsible for the expense related to the creation of a building. 2 Methodologies Published information was used for the majority of data provided in this paper that contains the following- Journal and magazine articles Publications related to trade organizations Marketing publications and white papers by software vendors Presentation of practitioners Academic papers Case studies Surveys Architects, developers and researchers were interviewed like, Sera Architects and Gerding Edlen Development, LLC which are both outside of Portland., Oregon. The selection of the firms was based on their prior experience with valid developments and implementations of BIM. Researchers like John Kunz and Martin Fischer from Stanford University and Professor Chuck Eastman from Georgia Tech were interviewed. Selection of individuals was based on their expertise with BIM related techniques and architectural computing. The main criterion was to find out the reliability of the data with regards to the completion or near completion of the project. Case data from a yet to be started project has not been included since this paper is from the perspective of the developer. Statements from online publications, articles and interviews were not entirely in specification with the project and hence the same criterion was not used as the statements may refer to multiple project experiences. The different forms of data found in this paper ranges from quantitative data to qualitative opinions about time, cost and efficiency. Quantitative information on the performance of the project was taken into account to gauge the level of effectiveness of a particular modeling implementation or modeling. BIM technology is a fairly new concept and practitioners wanted to see proof of the value of the BIM implementation to a project before investing resources and time. The information from real projects shows this proof and the errors and lessons that have been learned from previous mistakes. The major portion if the quantified information seen in this paper is taken from development projects of major size like office and residential towers, schools, hotels and event centers. The bias in data is mainly due to lack of information on the use of BIM in small scale projects. There is a degree of uncertainty if the lack of information is the reason behind the application of BIM in small scale projects or whether the information related to small projects using BIM is not being published. Additional information on the small projects using BIM would further enhance the argument on the benefits of BIM. 2 Questionnaires 2.1 Objectives and sample This questionnaire has got two major objectives. The first is to survey and find the ratio of AEC companies in the U.S, U.K and other nations that use BIM. The next objective is to determine the benefits these companies enjoy from this technology. The AEC industry academics and practitioners were sent the questionnaire to fill up. Analysis was the focus for the two countries of U.K and U.S. U.S is clearly ahead of the rest in the development of the BIM technology. The companies in U.K have spent a lot of time to carry out research on this technology. Some of the companies are leaning towards this technology. Academics who participated in the research of BIM also took part in the questionnaire. Poverty Issue in Pakistan There are several facets to poverty in the country of Pakistan. The people suffering from poverty in Pakistan are secluded from basic amenities like clean drinking water, education, proper sanitation and health. This discourages them and their abilities while limiting their opportunities to get a safe and secure employment. This tends to the poor being secluded from society and exposes them to a sad affair of states. This problem only worsens as the government does not make any policies and plans for the betterment of these people and help them in the long run. The depth and extent of the poverty calculated from different ways based on different definitions and indices used but there is a general consensus regarding the shocking state of the people suffering from poverty. It has been agreed upon by all that the fight against poverty seen in the 1980à ¢Ã¢â€š ¬Ã¢â€ž ¢s has died down entirely. IF anything, the extent of poverty has only increased at the turn of the next decade as there was no per capita growth in GDP. The government in Pakistan on the basis of the information available regarding the current situation of the people living in poverty has agree with the IPRSP with respect to the trends in the prevalence of poverty. During this period, the Planning Division has enforced an official poverty line that is based on the norm of 2350 calories per adult per day. Strategy of poverty reduction The poverty reduction strategy has basically been put in place to help the needy who have long been suppressed by the conditions brought on to them on account of poverty. Those living under the poverty line in Pakistan have to face a lot of hardships on a daily basis and it is of essence to provide them with some facilities in order to improve their standard of living both socially and economically. The poverty reduction scheme of the Pakistan government is based on the following principles: Increasing the economic growth and keeping the macroeconomic condition stable. Human capital investment Expansion of social safety nets Bettering the governance The major steps and policies brought into effect by the Pakistan government are the following: Financial sector Reforms and Monetary Policy Market based indirect instruments are used to conduct the monetary policy in Pakistan. The free float exchange rate prevalent from July 2000 has meant that the monetary policy has a huge impact on the exchange rate, surpluses, rising current account and the liquidity as a result seen in the inter bank foreign exchange market, pressure exerted on the U.S$ and Rupee parity by H1-FY03. The state Bank of Pakistan has kept intact the cautious policy standpoint and mopped up the major portion of the excess liquidity from the inter bank market witch enabled the rupee to increase in value. The value of the rupee increased by just 3.1% throughout the period. The monetary standpoint adopted is unlikely to change if there is no shift in the inflation overview. There has been a drop in the average lending rates from fourteen percent in the NOV. 2001. To more than ten billion dollars in the recent time and the return from the National Savings Scheme instruments have decreased. The major parts of financial sector reforms are: Measures include elimination credit controls, interest rates and lower cash reserve ratio, development of financial market that include treasury bill market, inter bank market, increased competition, capital markets, high competition in between banks, foreign firms and privatization of financial institutions, strengthening prudential supervision and regulation, enforcement of anti money laundering law in FY04 made for establishment of Financial Intelligence Unit. The strategy for reducing strategy keeps in mind the social, economic and governance. The aim is to improve development that should be proportional to every citizen that includes the unemployed, poor, illiterate, ill health, poor sanitation and housing and unclean drinking water. The main objectives of the policy are: Providing the essential productive assets to those who are poor. Providing a safety net to take care of the very poor. Enhancing the capability of people with the help of human development programs. Providing the necessary resources to finance the programs made for reducing the poverty. Strengthening and reforming the institutions to deliver the public services in a better manner. Micro finance- The concept of micro credit has become a very helpful tool to enabling the poor in increasing their income. Reducing their vulnerability to shocks and building small businesses. Microfinance can be applied to more aspects like savings, credit and insurance as part of the broader services. This concept has many institutions like the First Microfinance bank, Kashf Foundation, First Women Bank and SME Bank. The disbursements and the beneficiaries of the microfinance can be seen in Table 10.1 for the period of 2008-2009, 2009-2010 and the target for 2010-2011. The State Bank of Pakistan has been very helpful in the encouragement that they have provided to Development Financial Institutions and banks to work towards the funding of Microfinance Institutions, NGOà ¢Ã¢â€š ¬Ã¢â€ž ¢s and Microfinance Banks in order to achieve the targeted outreach. TO further enhance the passage of funds to the field of microfinance, The State Bank of Pakistan has developed a Microfinance Credit Guarantee Facility or MCFG which helps in easing the constraints on credit. This is viewed as an incentive by the microfinance institutions and ultimately helps the general public in their fight against poverty and to get a new lease of life in the right direction. In accordance with the MCFG facility, The State Bank of Pakistan provides a guarantee cover to a percentage of forty on the principal amount in the scenario of a partial Guarantee and to a percent of twenty five in the scenario of First Loss Default Guarantee on the facility of credit being extended to the qu alifying borrowing institution by the lending institution. The micro finance institutions that are in place currently are sure to be supported strongly by the development of service and product innovations and also the enhancement to the access of credit for women Microfinance services are set for a considerable amount of expansion that will be seen both horizontally and vertically which will help in the long run for the strengthening of the framework for the financial services being provided from the legal point of view.

The Annunciation: A Painting by Francisco de Zurbaran :: Essays Papers

The Annunciation: A Painting by Francisco de Zurbaran Works of art can best be appreciated when the elements of design, the principles of design, and the iconography of the work are observed and understood. The Annunciation, a painting by the Spanish artist Francisco de Zurbaran, is a work of art that incorporates both the elements and principles of design. The iconography of the painting is of great importance as well as its aesthetic quality. The ability to create a picture of The Annunciation in one’s mind is a key factor in understanding the analysis of the work. Francisco de Zurbaran approaches the painting with a naturalistic style. The painting features a room in which a woman – like angel is seen at the left kneeling on the ground before the Virgin Mary. The figure of Mary is placed between a chair and a small wooden table draped with a green cloth. Mary disregards an open Bible on the table, as she appears solemn while staring at the floor. Floating above the two main figures in the upper left side of the painting are cherubs resting on a bed of clouds. They happily gaze down at Mary with eyes from Heaven. The Annunciation uses elements of design to create a visually pleasing picture. The visual elements consist of light, color, texture, shape, and line. The use of light is one of the most evident elements in this painting. The source of light is not directly visible in the painting, but appears as a radiant angelic host floating above the two main figures. Light emphasizes the fair skin of the Angel and Mary as they both look down towards a shadowy floor. Light also reflects the open Bible on the table suggesting emphasis on the holiness of Mary. The rest of the room remains eerily dark and dull. Color is used to draw attention to important characters and objects in the painting. The red of Mary’s shirt emphasizes her place as the main figure. A bright, yellow cloud floating above the room symbolizes the joy of the angelic figures. De Zurbaran uses warm colors in the foreground. The room, used as the background for the scene, is painted in dark colors utilizing different hues of gray and brown. An observer can also obtain a sense of texture in this painting.

Childhood Toys :: Essays Papers

Childhood Toys Wham, bang, hay-ya! Those were probably the kinds of sounds you might have heard if you passed by my room as a child. All of those greatly preformed sound effects came from none other than myself, unless I had a friends help who was of course only allowed to be the villain in whichever toys we were playing. I guess this interests me now because I can realize as an adult just how much watching certain shows, having certain toys, and playing certain games have had a part in shaping the person I am today. I can remember when I was the ring bearer at my aunt’s wedding, no more than five or six years old, and being caught on camera talking to my watch in the back of the church. â€Å"Everything’s ok here KIT, it’s all-clear†, is what I was saying. No, I wasn’t a disturbed child. I was imitating Michael Night, the normal guy with the not so normal talking car, who always saved the day on the show NightRider. GI Joe, He-Man, Teenage Mutant Ninja Turtles......I’ve been all of them (Or in my mind anyway). Also, like most kids, I probably could of single handedly kept up one of those toy makers with all of my purchases. I have to wonder though, if I hadn’t watched these shows and played these games, if I would be the same person I am today. Even today, maybe if people didn’t grow up watching Superman, Batman, the Hulk.......we wouldn’t have people who are as courageous as the firefighters and police we have at the World Trade Cen ter right now. After all, selflessness and courage are traits, which cannot be taught through an academy, they are things instilled in you from your childhood years. Possibly the years you were watching the â€Å"Caped Crusader† fight for good. I’m happy to have those memories, and maybe they are part of the reason I have wanted to be a police officer. Maybe we should think before we say no to our children next time the want that action figure at the toy store, who knows, it might be the reason they save somebodys life one day.

Othello: A Man of Love and Passion Essay

In this age of epic, fantasy, scientific fictions and other creative stories, people are sometimes bound to forget the best things found in the past, the origin of everything that we are enjoying now. One of the best examples is the literary masterpieces that can be found way back a long time ago. William Shakespeare’s works are considered one of the best ideas of all time. His works might have been millenniums ago, but are still passed generations to generations due to its all time effect and appeal to all the people at any age. Some of his famous works are the forbidden love of Romeo and Julie, the power of Macbeth, and of course, the Othello. Othello is a story that revolves about how love can grow deadly and fierce. Indeed, love is a precious thing that is sometimes shadowed by jealousy and betrayal. Racism is also tackled on the story, the story has shown a how a simple skin color can widely affect one’s whole life. The story circulated on the life of the major character Othello, he is greatly described nowadays this way: A noble â€Å"Moor†, in the service of the Venetian State, Othello is introduced to us in the very first scene by the term â€Å"Moor†, when Iago complains that Othello has made Cassio his lieutenant and not him. We also learn from Iago that Othello has a relationship with the fair Desdemona. Respected by the Duke of Venice, who is the first to address him by Gulin 2 name (Othello in Act I, Scene III) and who sends for him when Cypress is threatened by Turkish forces, Othello is continuously described by his critics (Brabantio, Iago) as a â€Å"Moor† a reference to his dark skinned appearance and a reference to the race of Muslim peoples of north-western Africa to which Othello belongs. Othello to sum it all up is a simple African prince who lives together with his family on Europe. On his stay on the premises of Europe, he had become a Venetian military with the rank as general. Being a soldier, he got to help other people in need, thus, making him more a bit more knowledgeable than other people with regards to women. In the middle of the story, Othello and Desdemona, the daughter of Barbatio, will eventually be married with each other. Othello can best symbolize men who are undergoing discrimination in the society just because their skin color is darker than other people, a fact they would have never meant to be. But indeed, despite of all this betrayals that succumbs his whole personality and lies of the people around him, he still manage to show his wife Desdemona his unconditional and true over just like any other man unto his wife. The story Othello is now known to be the mother of all modern drama due to its mass appeal and timely story.

The flask was stoppered and shaken carefully upside down several times. 5) More water was added to the flask about a cm below the graduation line. A dropper was used to accurately drop the right amount of water to the flask so the bottom of the meniscus was on the graduation line. 6) A 20mL pipette was used to put 20mL of sodium carbonate solution into each of the four 100mL conical flask. 3 drops of methyl orange indicator was added to each. 7) The burette was filled with the solution of brick cleaner. 8) The sodium carbonate solution was titrated with the solution of brick cleaner until there was a clear permanent colour change. 9) Steps 7 and 8 were repeated until 3 concordant results were Results: Weight Volumetric flask 78.968g Brick cleaner 6.00g Titre 1 2 3 Initial vol 2.3 23.4 3.0 Final vol 23.4 44.5 24.0 Vol added 21.1 21.1 21.0 Calculations: On page attached. Discussion: The weight for the brick cleaner may not be 6.00g as the volumetric flask was not weighed again with the brick cleaner in it because that step was forgotten. So the result above was taken from another student that did the prac. This will affect the results as the mass of the brick cleaner is used to determine the percentage by mass of HCL in brick cleaner. All 3 titres show that they are only within 0.1 of each other. The hypothesis has been disproved because it was suggested the 30% of HCL would be in brick cleaner and there’s only 2.4% although it’s not certain that those steps were done correctly. There were no problems encountered during this prac. Focus Questions: 8)a) the manufacturer says that brick cleaner is made up of around 35% HCL, which is a massive difference to the answer that was got in this prac but again question 7 was not done correctly. b) differences in class results occur because not everybody would have done the exact volume of brick cleaner, sodium carbonate etc as each other therefore the difference in results obtained. 9) To correctly clean up a spill of 20mL brick cleaner you would mop it up immediately, washing it away with massive amounts of water 10)a) volumetric flask= once with water twice with brick cleaner b) Burette= once with water twice with diluted solution of brick cleaner c) pipette= once with water twice with diluted brick cleaner d) conical flask=once with water twice with sodium carbonate solution Conclusion: To conclude, there should be 35% HCL in brick cleaner although it was found that there was only 2.4%

Basic Concepts of Effective Communication

Objectives: * Describe the nature of communication in science and technology; * Understand the meaningful process of communication; * Explain the components of communication; * Overcome their difficulties in communication; * Consider the most describable characteristics of an effective style for technical writing; and * Compare and contrast technical writing from nontechnical writing. The nature of Communication Communication comes from the Latin word con-meaning with, munus- meaning a business, communis meaning common, and commonico-to confer or to relate with one another.In layman’s language, communication emanates from the need to share ideas or information from one person to another by the use of symbols such as words, pictures, figures and graphs. Common Concepts about Communication Different authorities have common concepts about communication. Some of these are present hereunder. * Communication is a purposive activity which is prompted by need to express ideas, feeling s, attitude and course of action to attain a predetermined goal * Communication is the process of conveying and exchanging facts, ideas, and research results.Communication is a two-way process which entails a communicator and a receiver. * Communication is a continuing process which Is interactive. * Communication emerges in response to the different functions and contexts that it calls for. Be it oral or written, people communicate to ask and give information explain something, agree or argue with others, narrate or describe an event, report an accomplishment, and so forth. * Communication is needed when recent discoveries, inventions and developments in science and technology are to be disseminated.Its importance is also felt when pertinent information should be imparted through letters, reports and memoranda. People are by nature social beings. They have to interact to attain a common goal. In so doing, use of language to communicate their ideas, opinions and feelings is undeniab ly inevitable. In communication, the skillful use of language can readily influence the opinion beliefs, values and behaviors of the members of an organization. Particularly, the use of simple, concise and accurate language in giving instructions in a certain industry or firm can facilitate mutual understanding between and among employee and employers.Effective communication is one of the determiners of success in any organization. It is an essential instrument in implementing the goals and objectives of a company. It serves as a tool in decision- making , providing permanent record, information from top to bottom level of management, and the like. As such, it plays an important role in the operational efficiency of a form. Written communication, specification reports, could be considered as the prime mechanism by which technical men and businessmen transmit their messages to action. Likewise, jobs to be done in any firm or organization are formally requested through communication.F indings of researches are known through oral and written communication. Oral presentation of reports is usually done in top-level management meetings. Consider the following illustrations: * In the morning, the engineer listens to the weather bureau’s forecast for the day over the ratio. * For a panel discussion, the computer technician presents through Powerpoint each detail of the researcher’s report. * A Veterinary Medicine sophomore writes a research paper on â€Å"The Effects of Rabies on Humans†. Each of the abovementioned situations illustrates the call for communication.The individual, in each of the examples cited, enters the common, shared world of other human beings. Aside from oral and written communication, there are other means of communication like facial expressions, Gestures, nods, signal, marks on paper, electric data and others. However, the raw materials of language are the sounds made by the human voice and the written patterns that are form ed from with them. The Process of Communication The cycle of communication, according to Eugene White , can also be applied in oral communication for science and technology.This is usually done in presenting/reporting periodic activities during meetings with top management. The presentor will undergo eight stages: thinking, symbolizing, expressing, transmitting, receiving, decoding, reacting and monitoring. The speaker will think of what information will be provided to the audience. These ideas which will be transformed into words and sentences will be expressed to the listeners through an organized report. Such will affect the receiver via sound waves. As the message is sent, the reciever’s mind starts decoding the information.The value of the information to the listener/receiver and the clarity of presentation will affect the reactions. Being aware of the audience’s reaction, the presentor and ends with his monitoring activities. Components of the Communication Proce ss The communication process consists of the following components: A. Communication Situation- the particular context by which a need to tell something arises; B. Communicator- the provider of the information; C. Medium- this consist of oral and written modes of communication; D. Information-the message that will be imparted to a particular audience and; E.Receiver- the reader or listener of the information Reports in Communication Process The communication process consists of the following components: A. Communication Situation- the particular context by which a need to tell something arises. B. Communicator- the provider of the information. C. Medium- this consists of oral and written modes of communication. D. Information- the message that will be imparted to a particular audience. E. Receiver- the reader or listener of the information. Reports in the Communication Process How do reports fit into the communication process? It requires a minimum of two persons to communicate.In th e case of superior-subordinate relationship, communication usually emanates from the former if he/she wants a certain course of action to be done. The subordinate, who is the report writer, will research and gather facts in fulfillment of the assignment give to him. If the supervisor is satisfied with the information given, the communication process will stop temporarily. But if it does not meet his standards, additional work will be asked for. Thereby, the process of communication will start again. In sum, communication process is unsending- it’s a continuing process.Suppose the writer developed a description of the three phenomena, all in one paragraph. The paragraph would run quite long. Instead of one long paragraph, write three shorter ones, one on each phenomenon so that the material can be separated into small units. The style which is characterized by objectivity accuracy and conciseness should be utilized to communicate with people who belong to specialized professio ns. Example: Operation was becoming uneconomical both labor and full costs were more than what had been anticipated. -Adapted The word operation has different meanings to different people.In this case, it means a military action or mission. The scientific style of writing uses the third person and the passive voice for an impersonal approach in writing. If possible, avoid using â€Å"I† which will only lead to subjectivity. Technical writing is concerned with the action being done and not the person who has done action. This concept does not imply that the use of personal pronouns and verbs in the active voice is erroneous. However, the adaptation of such will also create another style of writing. Example: Set up the testing equipment in the laboratory and run three tests before I read the conclusions stated in this report. First Person, Singular, Active Voice) The testing equipment was set up in the laboratory and three tests were run before the conclusions stated in this re port. (Third Person, Passive Voice)-Adapted The second example is the style commonly found in technical reports. Qualities of Good and Effective Scientific and Technical Style Some of the qualities that could lead to a good and effective scientific and technical style are the following : * Honesty about facts * Care in obtaining and evaluating the facts * Accuracy in Presenting Data * Dignity and Restraint in Manner Objectivity in Analyzing and Interpreting Information Ways of Presenting Information Different companies have varied ways of presenting information. Some follow standard formats and others adopt their own format. This denotes that all technical writers must consider the usual practice of a certain company and the expectation of the receiver of the message. Hence, the use of formal or informal style is dependent upon context. Personal communication between business associates or personal friends calls for a Personal Writing Style while major reports which are submitted to top management are usually Impersonal in Style.It requires the format of a report. Requisites of a Technical Style The following are the requisites of a technical style in writing: Factual- refers to the orderly presentation of facts and ideas which could be achieved through careful planning. Functional- gives pertinent information and does not amuse or argue with anybody else. Informative- conveys facts and information. Objective- free from biases and prejudices, personal beliefs, emotions and attitudes. Concreteness- tantamount to definiteness, therefore generalizations should be supported by concrete facts or evidences.Consistency- the shift of tense and point of view in presenting a report will lead to inconsistency. Shifting of such will affect the personality of the writer and his style as well. For long and formal reports, it is better to use the third person consistently. Dignity- is achieved when the writer avoids colloquial/slang expressions and contractions. Simplicity- simple and familiar words are more emphatic and striking, hence, highfalutin words are less preferred in technical writing.

Concept of Prometheus Within Frankenstein

The concept of â€Å"Prometheus† within Mary Shelley’s â€Å"Frankenstein† Index Introduction – 3 Greek Promethean myth – 4 The Modern Prometheus – 5 Conclusion – 7 Bibliography – 8 Introduction In this short work, it will be made an explanation about what is the Greek Promethean myth and the message behind this myth. It will also be made a comparison between this message and the subjacent theme of the â€Å"Modern Prometheus† in Mary Shelley’s â€Å"Frankenstein†.Looking at the main character of Mary Shelley’s novel, it will also be important to describe in what way, and according to the Greek Promethean myth, Victor Frankenstein is the â€Å"Modern Prometheus† as referred in the title of the book. Greek Promethean myth The Promethean myth first appeared in the late 8th-century BC Greek epic poet Hesiod's Theogony. He was a son of the Titan Iapetus, one of the Oceanids (keepers of the water). In Greek mythology, Prometheus is a Titan whose name meant â€Å"forethought†, and indeed, he was said to have the ability to look into the future.Prometheus was the creator of mankind. The goddess Athene taught him architecture, astronomy, mathematics, navigation, medicine, and metallurgy, and he in turn taught them to humans. Zeus, the chief of the Greek gods, became angry at Prometheus for making people powerful by teaching them all these useful skills. He is the younger brother of Atlas, who was banished to Tartarus during the Titanomachy. Prometheus, however, sided with the gods in the war, having foreseen their victory. Helios and Epimetheus also chose to defect.In doing so, Prometheus also tried to persuade his brother Atlas and their father Iapetus to side with the Olympians, but both of them ignored his attempts. After the Great War, Prometheus fashioned man from clay and helped them, even to the point of severely angering Zeus and, when the gods chose Prometheus as arbiter in a dispute, he fooled the gullible Zeus into picking the worst parts of the sacrificial bull by hiding them under a rich layer of fat. To punish Prometheus, Zeus withheld fire from men. â€Å"Let them eat their flesh raw,† he declared.In response, Prometheus, snuck up to Mount Olympus, lit a torch from the sun, and hid a burning piece of charcoal in a hollow stalk. He slipped away with it and thus delivered fire to mankind. As punishment however, Zeus then chained him to a mountain for an Eagle to peck out his liver only to have it regenerated through the night. Heracles eventually killed the eagle and freed Prometheus, which Zeus allowed as he deemed Prometheus' suffering sufficient. Modern Prometheus The Modern Prometheus is Mary Shelley’s novel subtitle (though some modern publishings of the work now drop the subtitle, mentioning it only in an introduction).The term â€Å"Modern Prometheus† was actually coined by Immanuel Kant, referring to Benjamin Franklin and his experiments with electricity (this having to do with the way the creature was brought to life). As mentioned before, Prometheus was the Titan who created mankind, a task given to him by Zeus. He was to create a being with clay and water in the image of the gods. Prometheus taught man to hunt, read, and heal their sick, but after he tricked Zeus into accepting poor-quality offerings from humans, Zeus kept fire from mankind. Prometheus took back the fire from Zeus to give to man.When Zeus discovered this, he sentenced Prometheus to be eternally punished by fixing him to a rock where each day an eagle would peck out his liver, only for the liver to regrow the next day because of his immortality as a god. He was intended to suffer alone for all of eternity, but eventually Heracles (Hercules) released him. The way Prometheus makes man from clay and water is a relevant theme to Frankenstein, as Victor rebels against the laws of nature (how life is naturally made) and as a result is punished by his creation.The Titan in the Greek mythology of Prometheus parallels Victor Frankenstein. Victor's work by creating man by new means reflects the same innovative work of the Titan in creating humans. According to the original myth, fire was the one thing that man was not supposed to have because it belonged solely to the Gods, so when Prometheus stole fire for man, it meant that man was trespassing on immortal territory and man suffered because of Prometheus's gift. While Prometheus had his liver eaten every day, Victor didn’t have an organ ripped violently from his lower torso.But he did suffer a similar form of prolonged torture: all his loved ones being singled out and killed. He was not punished for stealing fire, but he was punished for trespassing on immortal territory by playing God. Also, fire is associated with goodness and knowledge. Fire is symbolic of human progress as well as the dangers of human invention, or possibly the dangers of natu re as opposed to humans, and Victor’s creature is paralleled to fire in the Greek Myth: the creature could be good or bad, depending on how much care you take in approaching it. And in Victor’s case, that would be no care at all.While fire is good and useful, bringing warmth and the ability to cook, it can also be a weapon, a massively destructive force, if not properly controlled. The monster is the same. He had so much potential for good. He desired to be good, gentle, kind, and loving, but at every turn he was denied. Because of this he became a destructive force bent on the ruin of his maker. Victor Frankenstein is plagued by his creation. He is hunted, haunted, and tormented. The rest of his life becomes a game, a chase between creator and created. Much like Prometheus, Frankenstein suffers greatly for the good he tried to do. However, there are differences.Fire is an unthinking, unfeeling thing. It need not be taught. It does not require love. Fire did not requir e anything from Prometheus. The monster, on the other hand, was a being of great depth and feeling. He was capable of growth and good, but his master neglected and abandoned him. Frankenstein should not have abandoned the thing he created. He should have faced what he had done and given it a chance at a better life. There is also an other interpretation for this, perhaps a more plain one. In more recent science fiction, the Promethean myth is applied in the following way: mankind receives technology that is beyond their understanding.For instance, in the TV show â€Å"Stargate†, the first human interstellar ship is called â€Å"Prometheus† and it is build with the help of an alien race. This concept can also be applied to the work of Mary Shelley, explaining that men do require time and study to understand things as they truly are. The creature was not bad. It was made bad by men surrounding it. So, it can be said that both Prometheus and Frankenstein successfully crea ted human life and faced results not in line with their expectations. In an attempt to help their creations, both Prometheus and Victor Frankenstein caused more damage and disorder.This eventually led to the harm of both, either through death or eternal torture. Conclusion As we could see, there are many similarities between the stories of Prometheus and Victor Frankenstein. Both tried to do â€Å"bend† the rules, in order to achieve something they believed would be beneficial. But in the end, they both caused more harm than good. Bibliography Shelley, Mary.

Stress and Fatigue in Police Personel and how it affects them Research Paper

Stress and Fatigue in Police Personel and how it affects them - Research Paper Example Research has also revealed that male and female police personnel perceive stress and fatigue differently (Zhao, et al; 2002).According to Keinan & Pines (2007), professional stress always directly impacts work performance of the employees; since police job is a sensitive and significant profession, there should be some strategy to reduce this work stress faced by police personnel. 1.2 Nature of Job Dealing with stress greatly depends upon one’s coping skills, however, Gaines & Jermier, 1983) have identified that job related fatigue is encouraged and elevated due to emotional exhaustion in high stress organizations (Zhao, et al; 2002). Police department in itself is a high stress department where police personnel get exposure to all dark and criminal sides of life. Gaines & Jermier (1983) further point out that the nature of police job and mandate of police in society is a bit contradictory and emotionally critical; which is why special attention is needed in this field to devi se and implement stress reduction strategies. 2. REVIEW OF RELEVANT LITERATURE A lot of academic and scholarly literature is available on the topic. Some of the relevant researches are reviewed under the three categories below: 2.1Causes of Stress and Fatigue among Police Personnel and its effects Abdollahi (2002) conducted a detailed review based study to investigate the stressors faced by police force personnel. The results of the study revealed four categories of stressors: Intra personal (Factors related to personality), Occupational, organizational and health related. According to Haines (2003), more police officers face stress due top relationships rather than job, because the tough nature of police job impacts their personal and family life. In another study, White and colleagues (1985) explored the factors that cause stress among police professional and found that these stressors can be broadly distributed into the three categories namely: physical or psychological threat, l ack of support and evaluation systems. Research has also focused on the job burnout in prison department. One study by Keinan & Pines (2007) has revealed that not only there are differences in perceived stress among personnel from various police departments like security, administration and treatment; differences are also found in stress level experience as per seniority position or rank wise. The main stressors identified include: working extra shifts without compensation, low salary packages and excessive work load. Boyce (2006) has explained stressors faced by police personnel in terms of external and internal factors. External factors of stress as per Boyce (2006) include: negative publicity, untimely court appearances, distorted police related press accounts, negative attitude and discouragement from friends and family on choice of profession. 2.2 Gender differences in Police Stress According to Boyce (2006), the female police personnel face an extra stress of proving themselve s since their ‘handling the situation’ skills are more often questioned as compared to those of males. Gachter and colleagues (2009) investigated gender differences in stress among police personnel. They measured stress on two scales, one for physical and other for psychological stress. Their findings were
