Comparing Scal Measurements And Pore Network Flow Environmental Sciences Essay

In this thesis undertaking, a comparative analysis between parametric quantities from an bing experimental informations of SCAL measurings and pore web flow theoretical accounts is carried out. The SCAL parametric quantities include comparative permeableness and capillary force per unit area. The experimental dataset was obtained from a big figure of sandstone Fieldss consisting capillary force per unit area and comparative permeableness informations for drainage and imbibition. The curves from different procedures were obtained from suiting theoretical accounts such as: Corey or power jurisprudence ( comparative permeableness ) , Brooks & A ; Corey ( drainage capillary force per unit area ) and Skjaeveland ( primary imbibition capillary force per unit area ) . In add-on, correlativities were established between curve parametric quantities and permeability/porosity and wettability for the complete subset of sandstone stones. In the same manner, a set of statistical practical stones w as created utilizing the procedure based Reconstruction technique. The Reconstruction starts from the grain size distribution of certain sedimentary stone type such as Fontainebleau, Bentheim, Berea and a customized North Sea reservoir in order to imitate the natural procedures of organizing sedimentary stones ; i.e. deposit, compression and diagenesis. This technique allowed the creative activity of a sum of 34 sandstone practical stones with different petrophysical belongingss. Subsequently, the pore web theoretical accounts were extracted and a sum of 3210 pore web flow theoretical accounts were obtained with changing oil-wet pore fraction, contact angles ( making 3 different conditions ) and administering oil-wet elements based on pore size: uncorrelated with pore size ( random ) , preferred large-pores and preferred small-pores. The information points obtained from the pore web flow theoretical accounts were fitted by implementing the Marquard-Levenberg and Trust Region algorit hm curve suiting techniques utilizing the same theoretical account curves explained before ( Corey, Brooks & A ; Corey and Skjaeveland ) . In a undermentioned measure suiting parametric quantities were plotted against permeability/porosity and wettability index giving a 2nd set of correlativities. Both sets of informations were compared ensuing in understandings in some instances and dissensions in others. It was found that for primary drainage all parametric quantities agreed good ( Pe, Sir ) but the curve form factor a demoing lower tendency values compared with the experimental dataset. The ground might be associated with either the absence of kineticss effects in the pore web theoretical accounts or the unsimilarities in the grain size distribution. Parameters for primary imbibition showed some understandings every bit good as dissensions. In footings of capillary force per unit area parametric quantities, the oil curve form factor ao showed a comparatively good correlativity wi th regard to experimental informations and proposing that the experimental nucleus sample should be classified as intermediate-wet. In add-on, the H2O curve form factor aw pore web values resulted in slightly higher than experimental informations. It is of import to observe that the experimental value of aw was fixed at 0.2 accounting for non dependable experimental values at low impregnations. With respect to the entry force per unit areas, cw showed comparative similar values as to experimental informations whereas carbon monoxide was somewhat lower. Furthermore, the pore web flow theoretical accounts wettability consequences were compared with the experimental informations utilizing different contact angle ranges, changing the oil-wet pore fraction and altering the distributing of oil-wet elements based on pore size. No clear correlativity was found for mixed-wet and fractionally-wet wettability categories with theoretical tendencies. However, some variables did act upon the wett ability of the pore web flow theoretical accounts. Both comparative permeableness curves, form and values showed some sensitiveness when analyzed with different pore-scale supplanting mechanism, oil-wet pore fraction, contact angle and pore size distribution. It is of import to take the possible being of mistakes into history for both, experimental dataset, every bit good as the curve fitting process and some failings related to the pore-scale physical premises in pore web mold.1. IntroductionPresents due to the necessity of understanding how the hydrocarbon recovery could be increased as a effect of the world-wide depletion of conventional oil reservoirs, several elaborate surveies of the reservoirs are carried out. Normally to obtain a stone sample from a reservoir, a nucleus must be cut from it. Subsequently, the nucleus must be shipped to research lab installations where a sample must be collected. Laboratory experiments performed on reservoir nucleuss have been the chief beginning of informations, nevertheless, these nucleuss have to go through through a long and boring procedure before any information can be acquired. These procedures include cleansing, criterion and particular nucleus analysis, ageing in order to find petrophysical belongingss such as porousness, seawater permeableness, capillary force per unit area, comparative permeableness and others. The most appropriate handling and readying processs vary with the ultimate aim of the nucleus analysis. From a common nucleus analysis, belongingss such as: porousness, permeableness in different waies, residuary oil impregnation and connate H2O impregnation can be obtained. In contrast, for particular nucleus analysis samples are handled with particular attention to reconstruct the reservoir wettability conditions in order to use measurings. The informations obtained could be: capillary force per unit area, comparative permeableness, wettability and residuary oil impregnation. Therefore, a tool that could potentially supply the nexus between the reservoir sample and the indispensable information required without holding to execute research lab experiments is used in this work. Its prognostic capablenesss ( still non proved engineering ) are based on pore web theoretical accounts of digital stone. Network theoretical accounts were pioneered by Fatt in the 1950s [ 3 ] by administering the pores and pharynxs on a regular planar lattice and consecutive make fulling them in the order of inscribed radius utilizing the Young-Laplace equation. During his research, he was able to formalize the pore web theoretical account with experimental informations and to obtain capillary force per unit area and comparative permeableness curves for drainage as a map of mean impregnation. At the same clip, the classical infiltration theory was introduced by Broadbent and Hammersley [ 4 ] , patterning the random flow of a fluid through a medium and depicting how elements of the medium independently permit or fail to allow transition. However, farther progresss from Fatt ‘s position did non happen until the early 80s, when Larson et Al. [ 5 ] , looking at pore degree natural philosophies combined the infiltration theory with a stochastic attack to foretell the distribution of the non-wetting stage during two stage flow. Since so, understanding of the implicit in physical mechanisms and the function of pore-space geometry and topology has been increasing. Lenormand et Al. [ 6 ] , K.K. Mohanty et Al. [ 7 ] used theoretical accounts with rectangular cross-section capillaries to detect and depict the supplanting processes during imbibition. These theoretical accounts are still the foundations for web mold: piston-like supplanting, snap-off and pore-body filling, leting the pore-scale natural philosophies of supplanting to be understood. Thereafter in the early 90s, two-phase and three-phase web theoretical accounts and the ability to include wettability change were developed by several writers. Kovscek et Al. [ 8 ] , incorporated thin wetting movie forces into a aggregation of capillary tubings theoretical account to depict the geological development of alleged mixed-wettability in reservoir stones. Their theoretical account emphasizes the singular function of thin movies. Blunt [ 9 ] extended their analysis to different fractions of oil-wet pores, contact angles and initial H2O impregnation. Sahimi et Al. [ 10 ] , developed a two stage comparative permeableness theory utilizing stochastic constructs from infiltration theory. The extension of the three -phase flow web theoretical accounts to existent porous media has been complicated by the trouble of depicting the 3-D pore construction of existent stones. Therefore, the usage of webs derived from a existent porous medium was foremost introduced by Bryant et Al. [ 11 ] by pull outing their web from a random close wadding of every bit sized domains and doing anticipations of comparative permeableness, capillary force per unit area and electrical conduction. Widening this attack for a wider set of sedimentary stones, Oren et Al. [ 12 ] introduced a procedure based method which mimics the terminal province of the geological procedure that formed the stone. This attack has proved its foretelling capablenesss in several plants [ 13, 14, 15 ] . Nowadays, many groups of research are dedicated to the country of pore web patterning, such as Imperial College, Heriot-Watt University, Australian National University and Numerical Rocks. Digital stone natural philosophies or pore web mold is an emerging field that may add a great potency for the approaching old ages. In this work, the experimental dataset used was antecedently generated in-house by Shell International Exploration and Production B.V. , happening correlativities between SCAL parametric quantities and porosity/permeability measurings for drainage and imbibition. The capillary force per unit area was obtained by utilizing the extractor method where a cylindrical sample is foremost saturated with oil and mounted in a extractor in order to whirl in stairss of increasing rate. The centrifugal forces throw oil from the sample, while drawing environing H2O into the sample. The continuance of each velocity measure must be sufficient for production of oil to discontinue. In add-on, comparative permeableness measurings were done utilizing steady province methods. In each experiment, fluids are injected at changeless rate and fractional flow. The force per unit area bead and impregnation are non recorded until they reach stable values. Then the fractional flow is changed and the process is re peated. The consequences obtained from research lab experiments are stored in a database and the information is analyzed looking at some tendencies or correlativities. Smits and Jing [ 2 ] , investigated comparative permeableness curves utilizing the Corey Model or â€Å" power jurisprudence † . He linked the six Corey parametric quantities to happen out their several correlativities to water/oil imbibition. The survey included 13 sandstone reservoirs. Cense [ 1 ] suggested a set of correlativities utilizing the consequences of laboratory experiments on water/oil primary drainage and imbibition for capillary force per unit area in sandstone and carbonate reservoirs. From these two plants, the best tantrum for drainage is based on the semi-empirical relationship of Brooks and Corey [ 16 ] parametric quantities: and ( 1.1 ) where Personal computer is the capillary force per unit area in Pascal, Pe is the entry force per unit area in Pascal, Sr is the decreased impregnation, Sir is the irreducible H2O impregnation and a is the curve form factor. For imbibition and secondary drainage, a Skjaeveland [ 17 ] tantrum is used to depict the capillary force per unit area curves: ( 1.2 ) and ( 1.3 ) where cw is the H2O entry force per unit area, carbon monoxide is the oil entry force per unit area, aw, ao are the H2O and oil curves shape factor severally. The equation 1.2 consists of two subdivisions. The first subdivision is called H2O subdivision and is defined by parametric quantities cw, aw and Srw whereas the parametric quantities co, ao and Sro define the 2nd subdivision or so called oil subdivision. During this work, practical stones utilizing a procedure based Reconstruction technique are created and their several pore webs are extracted. Once the pore web theoretical account is created, the flow in the web is modeled to obtain for primary drainage, primary imbibition and secondary drainage, the comparative permeableness and capillary force per unit area curves. A set of suiting parametric quantities that describes old curves are correlated with permeableness, porousness and wettability. Therefore, the importance of this work relies on an alternate attack capable to place failings and strengths resulted from the informations comparing between the web flow mold and research lab experiments. The workflow procedure of this work is done utilizing the e-Core package ( see appendix A ) . It is chiefly conformed by three phases: the first one is related to the creative activity of the geological theoretical account, where the digital stone samples are generated utilizing petrophysical parametric quantities. The geological theoretical accounts have to go through through the different typical chief organizing sandstone procedures, such as: deposit, compression and diagenesis. Second, the pore web is extracted from the geological theoretical account where several nodes and links stand foring the pores and pharynxs of the stone are recreated. Last, the pore web flow theoretical accounts describes the stone fluid interaction occurred at pore-scale. This is done in order to foretell constituent relationships of comparative permeableness and capillary force per unit area. Once the constituent relationships are acquired, some analytical correlativities are used in order to happen a representative tendency between the pore web flow theoretical accounts informations and research lab informations.

The Twin Paradoxical: Acme and Omega Electronics Study Case

The Paradoxical Twins: Acme and Omega Electronics E-mail : [email  protected] co. id Introduction: In this case, two similar electronic companies named Acme and Omega, Which situated closely one to another. Both of them are originally formed from the same company, but they grew into completely different companies. Below listed their company details and unique points, right after company’s establishment: Acme: ? ? ? ? ? ? Company size: 550 employees, with annual sales $10 million The president: John TylerRetaining the original management and upgrading general manager to president Has a relatively more effective management and bigger net profits Management culture: bureaucracy/ hierarchy culture, it is stated by John Tyler â€Å"he retained the basic structure† and company has a well structured organization chart. Management get used to routine and predicted activity, stated in â€Å"Tyler was confident that has the demand had not been so great†¦. †, and â⠂¬Å"we have been able to beat Omega regularly.. † Omega: ? ? ? ? ? ? Company size: 480 employees, with annual sales $8 millionThe president: Jim Rawls Hired a new president who is a former director of a large electronics research laboratory, and upgrading several of the existing personnel within the plant. Relaying on face to face communication which leads to ineffective time management. Management culture: adhocracy/ entrepreneurial culture, stated in â€Å"Jim Rawls did not believe in organization charts†¦Ã¢â‚¬ , â€Å".. people from mechanical, electrical, production and industrial engineering got together.. †, and â€Å"Jim Rawls called a meeting on Friday, July 8, that included all departments head.. †Team oriented and project based organization are used, based on Jim Rawls’ background as a researcher and his capacity as the president. Case Summary: In July 1996, on of major photocopy manufacturer was looking for a subcontractor to assemble the memory unit, whereas this project worth $5-7 million. This project required 100 prototypes, and speed is a critical factor indeed. Both Acme and Omega had at most 2 weeks to get this project done. Acme Timeline: ? ? ? ? ? ? ? ? ? ? ? Monday (July 11th): Blueprint arrived and purchasing decision has been made by purchasing department.Tuesday (July 12th): mechanical engineering received manufacturing prints and evaluated their capabilities in completing this project. Wednesday (July 13th): Purchasing found that a particular component could not be purchased due to summer vacation in manufacturer region. Tyler decided to continue on producing with the missing component, and add the missing on the last stage. Friday (July 15th): Mechanical engineering informed an additional assembly time might be occurred because of the missing component. Monday (July 18th): Tyler got information from shipping department if most of the component has arrived.Foreman ignored the normal procedure of contac ting method engineers due to time limit. As a matter effect, the method engineers were very upset because they have no chance in designing proper layout. They had spent an entire weekend in analyzing the motion needed and his process was very inefficient and imbalanced. The foreman refuses to stop working, due to short time limit. Tyler got himself complained by the method engineers, but no one of them could change his decision and he wants to get all the prototypes ready as soon as possible. They just said each other if the units must be almost completely tear down in installing the missing unit.Friday (July 22nd): They have their last unit produced Tuesday (July 27th): Missing parts have delivered Wednesday (July 28th): Foreman found that they have to tear the units to install the missing units. Thursday (July 28th): Tyler decides to tear down all units. Friday (July 29th): 50 units of prototypes have been completed, and shipped without final inspection. Tuesday (August 2nd): The rest 50 units were shipped Omega ? ? ? Friday (July 8th): Jim Rawls called all department heads, and soon after he had received the blueprints. Monday (July 11th): Blueprint arrived and all department heads met to discuss this project.Wednesday (July 13th): They found that one component would not be ready in the next two weeks. Substitution of component must be made to keep the assembly time by using Ja pan material. ? ? ? Friday (July 15th): on process, industrial engineering department reported that the missing component would increase the assembly time. Relaying on this, the head of electrical engineering tested and ensured that the Japan component will definitely work. Monday (July 18th): All engineering gathered in finishing the units needed. Friday (July 22nd): all units were completely inspected and shipped.As a result, ten of Acme’s units were defective, while all Omega’s units passed the test. The client was disappointed with Acme’s delivery delay and i ncurred further delays in repairing the defective Acme units. However, rather than giving the entire contract to one firm, the final contract was split between Acme and Omega, with two added directives: maintained zero defects and reduced final cost. Analysis: 1. The importance of organization chart On the writer’s point of view, well structured organization chart is critical to illustrate distribution of management structure.This opinion supported by Colquitt which said organizational chart helps organization members and outsiders understand and comprehend how work is structured within the company (Colquitt et al, 2011). Based on Harvard Business Review, there would be several disadvantages occurred within a management with not organizational chart, which listed below: a. The â€Å"unworkable† job: an unworkable job means the absence of organizational chart, brings an unclear distribution or task and responsibility. One man has to do several tasks within the same time and reports to several bosses.As a matter effect, some tasks won’t be completed and reported when the time needed. b. Politics: An uncertain organization hierarchy often influences members to reach the highest level of organization hierarchy. Even more, inappropriate behavior might occur to get a higher authority and power. c. Over-regulation: The absence of organizational chart leads to uncertainty for job approval. One project must be approved some of majority member of organization before comes to realization. d. Cultural clashes: Unavailability of organizational chart often leads to unidentified organizational culture.Each member claims their own culture and also bring their previous company culture. 2. Distribution of authority in both company Based on Colquit (2011), elements of organizational structure divided into: a. Work Specialization ? Acme: individual specialization is used in Acme, where well structured of work flow has been divided into several steps of flow w hich given to different specific department. ? Omega: team work is used to bring the best performance, since the tendency is to get everyone involved in finishing one project. Everyone has almost similar knowledge and skills since everyone does all things together. . Chain of Command ? Acme: Well structured chain of command in Acme, creates a clear reporting order from subordinates to the manager. ? Omega: Group approval is needed since almost everyone has an obligation to do everything together. Moreover decision can only be produced after team discussion. c. Span of Control ? Acme: Tall organization chart symbolized this span of control which in Acme it is shown by the organizational chart. ? Omega: Relatively flat organization chart, even though there is no organization chart. In Omega, everyone has almost the same responsibility and authority. d.Centralization ? Acme: Centralized decision maker where Tyler as the decision maker or Tyler’s approval is the key point on orga nization activities. ? Omega: Decentralized decision maker, where everyone was involved by Rawls. e. Formalization ? Acme: Standardized procedure with specific rule set to maintain working behavior in Acme, such as using memo as communication tool (Mechanistic Organization). ? Omega: Flexible procedure and direct communication were highly encouraged to avoid misunderstanding in Omega. The Organizational dimensions displayed as below: Source: Colquitt, Jason A et all (2011) 3.The influence of company strategy to company distribution of authority Colquitt (2011) mentioned that company strategy has an influence on organizational structure, which described as below: ? Mechanistic Organization Acme has a mechanistic organization where the efficiency strategy, and work specialization are the unique mark of this organization. ? Organic Organization Omega has an organic organization where lateral communication, decentralized knowledge, and low degree of work specialization to maximize organ ization performance. 4. Cost efficiency failure in Omega In writer’s opinion, there are several inefficiency recourses in Omega which ead to higher cost, which described below: ? People Management Rawls encourages everyone to get involved in certain project even though they not directly related with such project. Moreover, direct contact and discussion are recommended to eliminate misunderstanding. ? Time Management Inefficiency of people management causes inefficient time management which several jobs can’t be completed in the same time, whereas everyone involved in one job. ? Resource Management Omega has a tendency in wasting resources for a fast solution. In this case, Omega uses substitute product to replace the missing component.Even it’s perfectly fit with the requirement; this solution increases cost of production. 5. Personal recommendation to Omega Washington University highly recommends the organization restructured in Omega for a better management ro le. Well structured organization will give a clear view of everyone role, responsibility and authority. This recommendation can be broken down into several actions which are: ? Restructuring Organization Restructuring organization includes creating clear job description, organizational chart, adding and eliminating position. Omega should define each member’s position, task, responsibility and authority. Forming Labor Relation Labor relation is important in manufacturing company, since large numbers of labor are employed. This organization utilized as the communication medium between labor and company management. ? Change Management Change management is needed in restructuring organization, since many things must be socialize to different. This team prioritizes the change order and methods.

Methods Used to Assess Learners Writing Ability Assignment

Methods Used to Assess Learners Writing Ability - Assignment Example As a result of their proven utility, tests as well as other standardized assessments are broadly applied in educational settings. To reap the potential benefits that are associated with tests, it is critical that they are understood completely and their strengths and weaknesses evaluated (Wall & Walz, 2004). Testing is a special way of collecting information that can be employed while making decisions about a person, a program or an organization and tests consist of items that prompt responses from a person. Testing does not comprise of the simple administration of a set of questions or tasks that have to be performed as the tests need to be scored and the results used for evaluation (Wall & Walz, 2004). Essay tests are usually considered to be more valid as compared to multiple-choice questions when measuring the writing ability of students as they have the ability of sampling a broader range of composition skills. On the other hand, variance in the scores associated with essay tests can demonstrate irrelevant factors like speed and fluency under the pressure of time or penmanship (Weigle, 2002). Multiple choice testing over-predicts the performance of minority students as far as essay testing is concerned and there is no certainty as to whether these tests have fundamentally equivalent predictive validity for candidates who are not in the same academic discipline where what they are supposed to write is not the same. The best tests that assess writing ability blend both essay and multiple-choice questions but this approach may be too expensive while the alternatives that may be relatively cheaper may have a compromising effect on the quality of the assessment.

Nursing Models Essay Example | Topics and Well Written Essays - 1000 words

Nursing Models - Essay Example Numbers of important nurse theorists such as Clara Weeks-Shaw, Isabel Hampton Robb, Imogene King, Hester Frederick, Myra Levine, Hildegard Peplau, Bertha Harmer, and Virginia Henderson contributed to the emerging discipline by describing various nursing models throughout the late 19th - late 20th centuries (Wesley, 1995). Each model of nursing has two elements: a method to assess individual needs of the patient and a method to implement the adequate type of care. These elements are used to a document known as a 'care plan' that is employed to identify the essential characteristics of a patient's treatment by doctors, nurses or/and health professionals. The process of treatment is measured and the quality of a patient's care is evaluated with appropriate changes being done to the care plan (Polit, & Hungler, 1995). In the 19th century, nurses were predominantly viewed as mere executors of the doctor's prescribed care. Such limited perception of the nurse's function resulted in emergence of a set of biomedical models of nursing that continue to strongly affect the modern nursing practices (Snyder, 2001). The key characteristic of the biomedical model is excessive attention to pathophysiology and altered homeostasis which did not allow advocates of this approach to properly identify individual differences between the patients. Consequently, although the biomedical model was effective for traditional medical and physical care, it failed repeatedly in cases which went beyond traditional frameworks: the focus on the treatment of disease prevented the nurses and doctors from making appropriate account of sociocultural, psychological, religious, or economic differences between the patients (Hawkins, 1987). The development of constructivist, functionalist, and interpretive epistemologies over the second half of the last century led many to revise the traditional biomedical models. As a result, the social model of nursing and healthcare that emerged in the 20th century highlighted the social aspects of treatment and nursing. While the biomedical model basically viewed all patients suffering from the same illness or disease as the same population, the social model emphasized the individual difference in religious, cultural, ethnic background of the patients (Wesley, 1995). The holistic principles promoted by the social models perfectly complement for the drawbacks of the biomedical models. The modern models of nursing aim to find the most effective combination of the biomedical and social models. Dorothy Johnson's Behavioural System Model "focuses on a behavioural system (the patient), its subsystems, and its environment" (Polit, & Hungler, 1995: 102). Johnson views the patient's behaviours are the primary objects of nursing analysis claiming the human being has seven behavioural subsystems: attachment, dependency, ingestive, eliminative, sexual, aggressive, and achievement. Each of these subsystems arises from a drive related to a desired goal, a set of likely responses specific to the individual, a group of choices as to effective responses, and the observable outcomes known as behaviour (Johnson, 1990). Some claim that nursing diagnoses in the Behavioural System Model may deal with insufficiency, discrepancy, incompatibility, or dominance Another well-known model of nursing

Assignment 6 - Essay Example This wildfire also resulted in the death of 86 people. This wildfire was so devastating that it prompted the Congress to set aside funds to assist the National Forest Service prevent and fight wildfires. Despite the measures that have been put in place to prevent wildfires, the U.S. still, continue to suffer from the effects of wildfires. Causes of Wildfire Both human and nature are responsible for wildfires witnessed in the U.S. According to Hamilton (2010), about 90% of wildfires that burn the U.S. forests and lands are started by humans. Firstly, arson attack is responsible for most wildfires in the U.S. Arson attacks happen when an individual deliberately starts fire with the aim of destroying the land of a person perceived as an enemy. In 2010 alone, the U.S. fire department reportedly responded to about 260,000 wildfires intentionally started by arsonists (The National Fire Protection, 2013). These intentional fires resulted in at least 390 deaths, and left at least 1,340 peopl e with serious injuries. The fires also resulted in the destruction of property worth $1.2 billion. In fact, the wildfire that burnt more than 147,000 acres of land in Southern California in 2009 was caused by arson, according to the U.S. Forest Service report (CNN, 2009). This wildfire also destroyed many homes in the northern part of Los Angeles. Most wildfires in the U.S. are also caused by people burning debris. Most people in the U.S. have the habit of burning debris. However, sometimes the wind ends up blowing the debris to a dry grass and forest cover resulting in massive wildfires as has been the case in Michigan. The Michigan Fire department reveals that most wildfires in the state are caused by people burning debris (Hamilton, 2010). Smoking is also blamed for the rising incidences of wildfires in the U.S., according to Hamilton (2010). It has been observed that some wildfires are started by discarded burning cigarettes. When an individual discards a burning cigarette on a dry grass or forest, this sometimes ends up triggering a massive wildfire that result in the destruction of several acres of land. A small percentage of wildfires in the U.S. are caused by sparks from moving trains, vehicle exhaust, and heavy equipment. Some of the wildfires that burn the U.S. forests are caused by nature, such as lightning and lava. Silverstein, Silvertein, and Nunn (2009) reveal that whereas 90% of wildfires are caused by humans, the remaining 10% are caused by nature. Normally, when lightning occurs, electric currents are sent to the earth’s surface resulting in wildfires. For instance, report indicates that about half of all wildfires in Florida are stated by lightning. Lightning is also responsible for about 2% of all wildfires in Michigan. Volcanic eruption is also responsible for a significant number of wildfires in the U.S. When an eruption occurs, hot magma is through onto the earth’s surface that cools down to form lava. However, when the ho t lava encounters dry grass or leaves, this sometimes starts wildfires as noted by Silverstein, Silvertein, and Nunn (2009). The physical nature of wildfires The physical nature of wildfire is very complex and depends largely on fuel type, geographical location, humidity, moisture content, temperature of an area and topography. For a wildfire to occur, the necessary elements must be available. Firstly, an ignition source

INTERNATIONAL PRODUCTION AND GOVERNANCE Essay Example | Topics and Well Written Essays - 2000 words

INTERNATIONAL PRODUCTION AND GOVERNANCE - Essay Example Food retailing is a subcategory of the retail industries. The business sector of food retailing is experiencing a dramatic change over these few years. The main driving forces of the retailing industry specifically the food industry are the consumers. They are creating the demand for the products that is increasing the scope for the expansion of this sector of the retail industry. The population growth of the developing countries and the increasing wealth in the hands of the consumers are influencing the rapid growth of these retail industries thus they are attracting more and more investments. (Retail, 2011) However these foreign investments in the food retailing sectors of other countries have certain influence on the economy of the country in which the investment is ultimately being made. The influence may to a certain extent impose a positive driven force for the country’s economy however it may have some adverse consequences. This is the scope of study of this paper. Impa ct of foreign direct investment on food retailing on receiver country’s economy The retail sectors of the modern economy had its base in the traditional retail supermarkets. Then with its emergence in the period of the last eight decades, it spreads slowly in the western region of the European continent and in the United States of America. During the period of their expansion in the Western Europe and United States there was hardly any foreign direct investment made in retails sectors of the economy. The spread of the retail sectors in the developing countries of the world were over five times faster than that in the developed countries in the past. The main reason behind this sudden significant transformation from traditional shops to retail was the huge amount of the foreign direct investment that the retail sector of these developing countries could attract. The expansion of retailing that had been achieved in the United States over the last eight decades had been achieved by the developing economy of Brazil within a period of just two decades only because of the huge rate of foreign investment that were made in the expanding sectors of the emerging economy. Moreover the sub sector of the food supply in the total retailing took more time of adjustments in the retail transformation in the developed economies. However this was an advantage for the sector as food retailing became much better equipped with capital and the support they received from the public sectors of the economies. The scenario of food sector in the developing economies of the world was a bit different. Small firms constitute majority of the food suppliers in the developing countries, which have a relatively low capital base, and lack of support from the public sectors of the countries. The growth of this sub sector of retailing in the developing economies of the world had been mainly due to the increased Foreign Direct Investments in these sectors. The Foreign Direct Investments poss ess the potential of improving the performance of the food retailing in the developing economies. The international expansion of the food retail sector had been substantially due to the investments made in the new emerging markets from the period of the nineties. (Reardon & Hopkins, 2006, p 522-524: McKinsey & Company, n.d, p. 7) The overall impact of the Foreign Direct investment in the food retail sector of the countries especially the developing ones are considered to be positive.

Business Communication 2 Assignment Example | Topics and Well Written Essays - 1500 words

Business Communication 2 - Assignment Example The facilitation of nonverbal communication is featured by the use of gestures, body language, facial expression of eye contact etc. Besides these features, the prospect of one person’s speech being different from another by way of voice, style and stress also constitutes to the functioning of nonverbal communication. Similarly, even in written format of communication, there are certain features like handwriting, organization of sentences and the word selection can altogether constitute an insignia of a person’s nonverbal communication elements. The following paragraphs give a clear-cut ideal of the scope, function and practical application of nonverbal communication in different spheres of life. It is also essential to recognize the prominence of the seven aspects of this model of contact between people such as paralanguage, body language, environment, distance, touch, time and eye contact has to be clearly evaluated for their use and management in the practical applic ation of nonverbal communication. Managing nonverbal communication Managing communication in the absence of words is arguably one of the most challenging tasks for the managers of organized groups. It is equally important to manage the feelings and their reflections in the daily life of individuals. There can be many examples of the regular life of individuals in which they have to adopt the process of nonverbal communication aspects. Sometimes a look or a gesture does the role of a great command. In other contexts, body language or time set for a regular action can influence the stakeholders of the process of exchange of information. There can be certain references to prove that the use of words and their pronunciation doubtlessly making the communication easier and more cognitive; however, the transfer of feelings and intellectual significance of a conversation or relationship between individuals is influenced more by non-verbal communication channels than the routine voice based elements. For instance, as Soon (2012) points out, a meeting of two people is specifically garnished by their shaking each other’s hands or by a hugging; in either case, the process of the meeting commences with the routine greeting of the time covering that meeting. From a certain angle of view, it is visibly annoying to find that the absence of such a physical endorsement of feelings makes the communication less effective. In order to manage the communication using the nonverbal media, the communicator has to effectively analyze and make use of his body language, touch and vocal qualities with the careful concern for time, space and situations. Moreover, it may also be regulated and empowered by the use of symbols and graphic pictures developed by the modern technology such as printed documents, visual projects and placards etc (Pecha Kucha 6 minutes 40 seconds). The functional success of a nonverbal medium is directly connected to time and environment at which it is used. If a person winks an eye at a stranger as a gesture of information transfer, it becomes provoking sometimes to the opposite person. For another instance, the combined atmosphere and distance effect in a nonverbal communication event matters to a great extent in the completion of a meaningful transfer of information. In military operations and surgical or scientific experimental environments, the need for gestures as a device is necessary; and the right cognitive effect of this is analysed by the timing of such

Grand Theft Auto's Detrimental Impact toward Gamers Essay

Grand Theft Auto's Detrimental Impact toward Gamers - Essay Example This paper has brought out the fact that incarceration is one of the major consequences for youth and young adults arrested for committing violent crimes. The violent crimes include murder, rape, robbery, and aggravated assault (Delgado, 2001, p. 3). This, however has not appeased society nor has it abated one's fears of crime and its circumstances, which games such as grand thief auto have contributed to. Much attention has been paid to the propitious drop in the nation's crime rates, and more specifically, the murder rate. An increased rate of incarceration is considered one of the key factors behind this drop, although a number of notable criminologists disagree. Incarceration is one of the major consequences for youth and young adults arrested for committing violent crimes such as murder, rape, robbery, and aggravated assault .(Delgado, 2001, p. 3) This decrease however has not appeased society nor has it abated one's fears of crime and its circumstances. Researchers continue to report that crimes are however densely populated in urban communities; and usually consist of black on black crimes. On the other hand, it is imperative that one accept that urban areas are not the only locations where crimes are committed. In fact, there are various types of crimes that continue to occur because of the violence in video games Since the early 1960s, research evidence has been accumulating that suggests that exposure to violence in television, movies, video games, cell phones, and on the Internet increases the risk of violent behavior on the viewer's part, just as growing up in an environment filled with real violence increases the risk of them behaving violently. In the current review this research evidence is critically assessed and the psychological theory that explains why exposure to violence has detrimental effects for both the short and long-term is elaborated. Finally the size of the "media violence effect" is compared with some other well-known threats to society to estimate how important a threat it should be considered (Huesmann). Evidence has shown that researchers examine the correlations between race and crime, as well as the discrimination that occurs when classification of crimes and its perpetrators come into account.(Knepper, 2000, p. 15) There is however not an objective definition of race given. Knepper continues to express that current statistical methods are not accurate nor due they portray the proper picture of current criminals and their circumstances. Knepper questions the idea of whether or not African Americans do in fact show a higher instance of criminality than others do, or are the statistics biased and skewed in nature. He concludes that there are currently four officials races used for classification: White, black, American Indian/Alaskan Native, and Asian and Pacific Islander and two official ethnic groups: Hispanic origin and not of Hispanic origin. This is also shown in the game Grand Thief Auto, which race is related to crime. Furthermore, it has been discussed that when it comes to crime certain racial groups are thought to commit certain crimes. From there, the death penalty is extremely racial because some people feel that individuals that are not of the white race are quickly sentenced to death. Fortunately, this is only a feeling among minority groups due to the fact that they are among the minorities. Statistics show whites are served the

Dimensions of Word Meaning

Dimensions of Word Meaning NGUYEN QUANG NGOAN Introduction The issue of defining and clearing the meaning of the words is by no means an easy talk. In other words, words are names or lables for things. Besides, linguists also realize the need to distinguish what a word or expression denotes from what they can be used to refer to, we will identify the difference between denotation and reference. There are many different ideas that the meaning of a word reflects reality or express human conceptualization of reality, as it were. However, we will discuss about various attempts designed to define probably one of the most difficult issues of semantics -meaning. Problems Depending on what it is understood by meaning, we can distinguish two main semantic theories: the referential / denotational approach-meaning is the action of putting words into relationship with the world; the representational /conceptual approach-meaning is the notion, the concept or the mental image of the object or situation in reality as reflected in mans mind. The two basic types of meaning were first mentioned by S. Stati in 1971- referential definitions which analyse meaning in terms of the relation symbol- object /referent; conceptual definitions which regard the relation symbol- thought/reference. 2.1 .Denotational /Referential Theories of Meaning. Before describing the characteristics of these theories, a clarification of the terms used is necessary. All languages allow speakers to describe or model aspects of what they perceive. In semantics the action of picking out or identifying individuals/ locations with words is called referring/denoting. To some linguists the two terms, denote and refer are synonymous. J. Saeed (1997: 23) gives two examples of proper names whose corresponding referents are easily recognizable e. g. I saw Michael Jackson on TV last night. We have just flown back from Paris. The underlined words refer to/denote the famous singer, respectively the capital of France, even if in some contexts they may be used to designate a person different from the singer, or a locality other than the capital of France. To John Lyons the terms denote and refer are not synonymous. The former is used to express the relationship linguistic expression- world, whereas the latter is used for the action of a speaker in picking out entities in the world. In the example A sparrow flew into the room. A sparrow and the room are NPs that refer to things in the world.; room, sparrow denote classes of items. In conclusion, referring is what speakers do and denoting is a propertyof words. Denotation is a stable relationship in a language, it doesnt depend on anyones use of the word unlike the action of referring. Returning to the problem of theories of meaning, they are called referential/ denotational when their basic premise is that we can give the meaning of words and sentences by showing how they relate to situations- proper names denote individuals, nouns denote entities or sets of individuals, verbs denote actions, adverbs denote properties of actions, adjectives denote properties of individuals-.In case of sentences, they denote situations and events. The difference in meaning between a sentence and its negative counterpart arises from the fact that they describe two situations e. g. There is a book on the shelf. There isnt a book on the shelf. Referential theories consider meaning to be something outside the world itself, an extra-linguistic entity. This means reducing the linguistic sign, i. e. the word to its material aspect, be it phonic or graphic. The impossibility of equating meaning with the object denoted by a given word can be explained considering three major reasons the identity meaning-object would leave meaning to a large extent undefined because not all the characteristic traits of an object as an extra- linguistic reality are identical with the distinctive features of lexical meaning; not all words have a referent in the outside world; there are: non- referring expressions so, very, maybe, if, not, etc. referring expressions used generically: e. g. A murder is a serious felony. words like nouns, pronouns with variable reference depending on the context: e. g. The president decides on the foreign policy. She didnt know what to say. words which have no corresponding object in the real world in general or at a certain moment: e. g. The unicorn is a mythical animal. She wants to make a cake this evening. different expressions/words that can be used for the same referent, the meaning reflecting the perspective from which the referent is viewed e. g. The morning star is the same thing as the evening star. The president of the USA/ George Bush/ Barbara Bushs husband was to deliver a speech. Besides the referential differences between expressions, we can make useful distinctions among the things referred to by expressions-referent thing picked out by uttering the expression in a particular context; extension of an expression = set of things which could possibly be the referent of that expression. In Lyons terminology the relationship between an expression and its extension is called denotation.(Saeed 1997: 27) A distinction currently made by modern linguists is that between the denotation of a word and the connotations associated with it. For most linguists, denotation represents the cognitive or communicative aspect of meaning (Schaff 1965), while connotation stands for the emotional overtones a speaker usually associates with each individual use of a word. Denotative meaning accounts for the relationship between the linguistic sign and its denotatum. But one shouldnt equate denotation with the denotatum.What is the denotation of a word which has no denotatum. As far as the attitude of the speaker is concerned, denotation is regarded as neutral, since its function is simply to convey the informational load carried by a word. The connotative aspects of meaning are highly subjective, springing from personal experiences, which a speaker has had of a given word and also from his/her attitude towards his/ her utterance and/ or towards the interlocutors (Leech, 1990: 14). For example dwelling, house, home, abode, residence have the same denotation but different connotations. Given their highly individual nature, connotations seem to be unrepeatable but, on the other hand, in many instances, the social nature of individual experience makes some connotative shades of meaning shared by practically all the speakers of a language. It is very difficult to draw a hard line between denotation and connotation in meaning analysis, due to the fact that elements of connotation are drawn into what is referred to as basic, denotative meaning. By taking into account connotative overtones of meaning, its analysis has been introduced a new dimension, the pragmatic one. Talking about reference involves talking about nominals- names and noun phrases. They are labels for people, places, etc. Context is important in the use of names; names are definite in that they carry the speakers assumption that his/ her audience can identify the referent (Saeed, 1997: 28). 2.2.The Relationship Between Sense And Reference The referent of an expression is often a thing or person in the world. The sense of an expression is not a thing at all it is an abstraction that can be entertained in the mind of a language users. Its difficult to say what sort of entity the sense of an expression it isà ¢Ã¢â€š ¬Ã‚ ¦it is useful to think of sense as that is a part of meaning of an expression that is left over when reference is factored out. Its much easier to say whether or not expressions have the same sense. Connotation and denotation revisited We have discussed the meaning of a word, it helps to know the difference between denotation and connotation. These two terms are easy to confuse because they describe related concepts. Moreover, both denotation and connotation stem from the Latin word. The connotation of a word is the additional meaning that the word has beyond its denotative meaning. It shows peoples emotion and/or attitudes towards what the word refers to. The Denotation of a word is the core, central or referential meaning of the world found in a dictionary. In English, a content word may have its denotation described in term of a set of semantic features that serve to identify the particular concept associated with the word For example, the words home and house have similar denotations or primary meanings: a home is a shelter that is the usual residence of a person, family, or household, and a house is a building in which people live. However, these terms carry different associations or secondary meanings, also known as connotations. Many people would agree that home connotes a sense of belonging and comfort, whereas house conveys little more than a structure. The connotation of a word depends on cultural context and personal associations, but the denotation of a word is its standardized meaning within the English language. The change and development of meaning 3.1 .Change of meaning The development of vocabulary is the first of all reflected in the development of semantic structure of the words: new meaning of the words appear, some old meanings drop out of the language of coexist with the new ones. The first is extending the meanings of existing words or acquisition of new meaning by existing words based on the occurrence of a relationship between the old and new meaning. For example: 1. She turned a cold face to me 2. My brother is a pig => Semantic extensions Occurrence of a relationship between the old and new meaning 3.2. Causes of semantic change The factors accounting for semantic changes may be subdivided into three main groups: a. Extra-linguistic causes : various changes in the life of the speech community changes in economic and social structures changes in culture, knowledge, technology, arts changes of ideas, scientific concepts, way of life b. Linguistic factors : Ellipsis a change of meaning when the meaning of a word-combination is given to only one word of this combination For example: daily daily happening every day a daily newspaper daily a daily newspaper Discrimination of synonyms conflict of synonyms when a perfect synonym of a native word is borrowed from other language. For example: tide OE tide 1)time 2)season 3)hour from French time, season, hour Modern English tide regular rise and fall of the sea caused by the moon c. One more linguistic cause of semantic change is called fixed context. E.g. the word token brought into competition with the word sign and became restricted in use to a number of set expressions, such as love token, token of respect etc. and also became specialized in meaning. 3.3. Nature of semantic change: a. Restriction of meaning (narrowing) restriction of the types or referents denoted by the word. It can be illustrated by the semantic development of the word hound which used to denote dog of any breed but now denotes only a dog used in the chase. If the word with a new restricted meaning comes to be used in the specialized vocabulary of some limited group within the speech community it is usual to speak of the specialization of meaning. b. Extension of meaning (widening ) application of the word to wider variety of referents It may be illustrated by the word target which originally meant a small round shield but now means anything that is fired at. If the word with extended meaning passed from the specialized vocabulary into common use, the result of the semantic change is described as generalization of meaning. The connotational meaning may be changed in two ways as follows: Amelioration (elevation) of meaning implies the improvement of the connotational component of meaning, e.g. the word minister originally denoted a servant but now a civil servant of higher rank, a person administrating a department of state. Deterioration (degradation) of the meaning implies the acquisition by the word of some derogatory emotive charge, e.g. the word boor was originally to denote a peasant and then acquired a derogatory connotational meaning and came to denote a clumsy or ill-bred fellow. Transference of meaning 4.1. Definition of metaphor: The other perspective from which we can approach semantic change is the nature of the change or the connection between the new and the old meaning. We also call this feature a transfer. The meaning can be transferred from the original to the new position via three main types of association: Metaphor is the semantic change based on the association of similarity between referents the meaning is transferred on the basic of the fact that the two referents resemble on onother. The basic structure of the metaphor is very simple. There is a thing we are talking about and that to which we are comparing it. The transference may be based on similarity of Shape. E.g: head of a cabbage, crane bulb, the teeth of a saw Position. E.g: the foot of mountain Movement. E.g: caterpillar of a tank. Function. E.g: the key to the mystery Colour. E.g: orange, rose. Size. E.g: midget, elephantine The names of the parts of human body are transferred to others objects ( the nose of a plane, the leg of the table) The names of animals are also often transferred to the human beings ( A cunning person is a fox, a spiteful person is a snake, a rude person is a bear, a hard-working person is a bee or a beaver, birds view, crocodile tears) Proper names transferred to common ones( a jealous person is called an Othello, an eloquent speaker is a Cicero.) 4.1.2. The differences between similes and metaphors Both compare things that are essentially unlike. Metaphor implies the comparison hidden comparison ( no formal element of comparison) Simile expresses the comparison by the use of some word or phrase like, as, than, similar to, resembles, seems. For example My love is a rose -> metaphor My love is like a rose -> comparison 4.1.3.The classifications of metaphor Living ( poetic, individual) when a word is used in unusual meaning and metaphor is felt E.g: Peace is our fortress. Faded (trite) metaphor is one which lost its freshness because of long use and became habitual E.g: Fruitful effort, golden youth, to fall in love Dead metaphor where metaphoric sense is not felt. Dead metaphor are words which lost their direct meaning and are used only figuratively E.g: To ponder originally meant to weigh, but it is used now only in the meaning to mediate, to consider thoughtfully 4.2. Definition of metonymy Metonymy (contiguity of meaning) the name of an attribute of a thing is used instead of the thing itself. In other words, metonymy can be defined as the substitution of one word for another with which it is associated. For example Hollywood is used as a metonym (an instance of metonymy) for American cinema, because of the fame and cultural identity of Hollywood, as the historical center of movie studios and movie stars. Proper names as metonymy can be illustrated by : read Shakspeare, listen to Mozart, it was a Waterlooà ¢Ã¢â€š ¬Ã‚ ¦ Major cases of metonymy: Use the name of container instead of the thing contained: E.g: to drink a glass, 2. Names of parts of human body may be used as symbols E.g: clever head, kind heart, 3. The concrete is used instead of abstract E.g: Let me give you a hand; to go to bed 4. The materials are used for the things is made of the materials E.g: glass 5. The name of the author is used for his works. E.g: Picasso, Ampere, Watts 6. Part is used for the whole and vice versa E.g: We all live under the same roof. She is wearing a fox. 7. The instrument which the doer uses in performing E.g. she is a good piano, 8.

The Role of Food in Erich Maria Remarque’s All Quiet in the Western Front and Elie Wiesel’s Night :: Comparison Compare Contrast Essays

The Role of Food in Erich Maria Remarque’s All Quiet in the Western Front and Elie Wiesel’s Night Food means different things to people in different countries of the world; pasta is common in Italy, hamburgers are a favorite in the US and tacos are a typical dish in Mexico. Human existence solely depends on this source of energy. A person’s fundamental need for food makes it a very important item, placing the people who control the food in a very high esteem. Consistency is also important in the delicate balance of life. Erich Maria Remarque, author of All Quiet in the Western Front, and Elie Wiesel, author of Night, both use food in their novels to convey this idea. Many of their thoughts and â€Å"meanings† concerning food paralleled one another. Food, one of the quintessential elements of life, plays a significant role in wartime experiences around the world and even in different time periods. Food is essential to basic life. It provides people with the energy to think, speak, walk, talk, and breathe. In preparation for the Jews deportation from the ghettos of Transylvania, â€Å"the (Jewish) women were busy cooking eggs, roasting meat, and baking cakes†(Wiesel, 13). The Jewish families realized how crucial food was to their lives even before they were faced with the daily condition of famine and death in the concentration camps. The need for food was increased dramatically with the introduction of the famine-like conditions of the camps. Wiesel admitted that, although he was incredibly hungry, he had refused to eat the plate of thick soup they served to the prisoners on the first day of camp because of his nature of being a â€Å"spoiled child†. But his attitude changed rapidly as he began to realize that his life span was going to be cut short if he continued to refuse to eat the food they served him. â€Å"By the third day, I (Elie Wiesel) was eating any kind of soup hungrily† (Wiesel, 40). His desire to live superseded his social characteristic of being â€Å"pampered†. Remarque also uses his characters to show to how a balanced diet promotes a person’s good health. Paul Bà ¤umer uses food to encourage Franz Kemmerich, his sick friend, â€Å"eat decently and you’ll soon be well again†¦Eating is the main thing† (Remarque, 30). Paul Bà ¤umer feels that good food can heal all afflictions. The bread supply of the soldiers in All Quiet on the Western Front was severely threatened when the rats became more and more numerous.

The Ebonics Controversy Essay -- Education Language Speaking Essays

The Ebonics Controversey What is the controversy over Ebonics about? The Internet offers diverse views on the Ebonics topic. Ebonics entered the lime light in December of 1996. The television and news media have made the issue unclear and have left many people wondering what the recent controversey over Ebonics entails. Long after the "six o'clock news" has comfused and abandoned the public on the issue of Ebonics, the Internet is alive with commentary. Sampled together, the pages present a social mood, conscience, or lack thereof. Depending on the page you visit, you will learn that the answers for the above question are mixed, jaded and sometimes very opinionated. The term "Ebonics" is the most recently coined name for a speech pattern that has been around for several hundred years. Synonyms for Ebonics include, but are not limited to, Black English, Black Vernacular, African American Vernacular English (AAVE),"Jive," "Rappin," even the derogatory term of "Nigger Talk"(Shabaz). The words "language" and"dialect" are ambiguous and often interchanged when they should not be, because of the confusion they can elicit. For my own use of the terms, I draw on the commonly available reference book, Webster's New World Dictionary. I will use the word "language" to signify " the vocal sounds, words, and the ways of combining them, common to a particular nation." When the term "dialect" is used, it is to signify "any form of speech considered as deviating from a real or imaginary standard speech [or language]". The use of these two words as interchangeable has led to much confusion, particularly in the case of the Oakland Unified School District 's resolution.

Neuropathology and Etiology of Alzheimer’s disease

Scientists have not yet fully come to full grips with the real causes of Alzheimer’s disease, however, one clear aspect of the development of this disease arise from a very complex chain of activities taking place in the brain over a long period of lifetime. It has been argued that genetic, environmental and even lifestyle factors have contributed to major causes of this disease. Risk and protective factors may include genetic, medical, biological, environmental, dietary, social and cultural aspects (Draper, 2004).In genetic aspect, APOE E2 is rare and creates protection against Alzheimer’s disease and in case it does occur in much later years than in people with APOE E3 and APOE E4. APOE E3 forms the most common Allele and is assumed to perform a neutral role in Alzheimer’s disease. This means it neither stimulates nor increases reactions that would lead to the development of Alzheimer’s. The APOE E4 occurs in the most common and occurs in approximately 4 0% in those who suffer from late onset Alzheimer’s disease. It is therefore common that people with APOE E4 are more likely to suffer from Alzheimer’s disease (Kuhn & Verity, 2007).It is infact known as the risk factor gene in that it increases one’s level of risk of developing Alzheimer’s disease. Early – onset Alzheimer’s disease, affecting few people is as a result of chromosome different gene mutations on specific chromosomes (Martinison&Musaswes, 1993). These include chromosome 21, 14 and chromosome 1 and all these produces abnormal proteins. Permanent changes in chromosome 21 lead to the creation of APP (Abnormal Amyloid Precursor Protein) while the same process in chromosome 14 leads to the formation of abnormal presenilin and mutation in chromosome 1 lead to creation of abnormal presenilin.Inheritance of even one of these genes from both or one parent is most likely to develop early onset Alzheimer’s disease. This kind of inhe ritance pattern is referred to as â€Å"abnormal dominant inheritance†. Another possible risk towards the development of Alzheimer’s disease is SOR1 (Roudier et al, 1991). This gene is solely responsible for the transportation of APP (Abnormal Amyloid Precursor Protein) within the cells and was discovered to be connected to Alzheimer’s disease. While it is present in low levels, beta amyloid levels increase and may have a negative effect on neurons (Ramanathan, 1997).The difference in genetic make up from one person to another either delays or completely prevents the onset of Alzheimer’s disease, also known as Familial Alzheimer’s disease. It is mainly inherited from parents and is caused by mutations in three genes. (APOE E2, APOE E3, APOE E4). There is a 50-50 chance of an offspring developing early onset Alzheimer’s diseases if one of the parents had it, averagely at the age of 30-60. As many as 5. 3 million Americans are living with Alzh eimer’s disease.It is know to destroy brain cells and hence cause problems with behavior, thinking and memory severely enough to affect work, lifelong hobbies or social infract It has been graded the sixth-leading cause of death in the United States (Mace & Rabins, 2007). There is no known cure to Alzheimer’s disease yet but an attempt to control it is going on. Scientists and researchers have come up with brain implants aimed to controlling it. These implants contain proteins called Nerve Growth Factors (NGF) which directly delivered to brain nerve cells, which in turn stimulates their growth and thus reduces the chances of their degeneration.Nerve Growth Factor (NGF) is responsible for controlling cell regeneration in the entire body but it is denied entry into the brain, this makes brain cells lack ability to self-regenerate (Taylor, 2006). Alzheimer’s’ disease has no cure however and irreversible. It is as a result of progressive brain damage characte rized by the building up of amyloid plagues and neurofibrillary tangles, lack of connection in the brain cells and the eventual death of these verve cells. Symptomatic treatment in combination with right support and proper service can lessen the pain of living with this disease.Change in different forms of lifestyle choices can also reduce the prevalence of this disease. It is a complex disease to understand because it affects individuals differently in the order in which symptoms come to surface, their order of appearance, the duration it lasts before end point and variation in the duration of stage. Increased vigor worldwide to find a lasting break through in proper treatment of this disease is underway (Coste, 2004). These include efforts to delay its onset, reduce late of its development and eliminate it from the body.Research also suggests that different forms of lifestyle such as nutrition, social activities; mentally involving activities are factors likely to reduce Alzheimer ’s disease. Progression of series of Alzheimer’s disease consists of five stages expanded to seven stages by the use of a Modified Global Deterioration scale (GDS). This scale assists doctors to measure the exact level of progression of the disease in a patient and administer right medication. Stages of Alzheimer’s disease include the early stage where the individual has mild impairenent arising from this disease (Pearce, 2007).Symptoms in this stage include rapid changes in mood and behavior, forgetfulness, and lack of proper communication. This group still contains most of their capabilities and thus needs very minimal life support. Further deterioration in this stage one leads to the middle stage. Mild cognitive impairment (MCI) is a condition in which a person has memory problems greater than those expected for his or her age. However, people with MCI do not have the personality changes or cognitive problems that characterize (Callone, 2007).Memory loss, dif ficulty in identifying people and objects are symptoms of middle stage although there may be little awareness. The late stage eventually does not allow verbal communication or one to take care of himself. This level require external support although their lives. The fourth stage, at end of life, is when one comes close to death and comfort is the main focus.Global Deterioration Scale (GDS) or Reisberg scale provides care givers with a better accurate measure of the level of deterioration stage.

Divine Roles Across Cultures Matrix Essay

Select one common divine role that recurs in world mythology. Possible options of divine roles include the following: father or mother divinities, divinities of war, home or hearth divinities, divinities of love, divinities of wisdom, divinities of medicine or health, divinities of the wind, divinities of agriculture, divinities of the sky, ruler of all the gods, and so on. Identify the role in the title of your matrix. Select two myths, each from a different culture, in which the divine role appears. Identify the divinity names and cultures in columns A and B. Complete the matrix by answering each of the five questions for both selected divinities. Title: Divinities of Love and Beauty Column A Divinity Name: Aphrodite Culture of Origin: Greek Column B Divinity Name: Freyja Culture of Origin: Norse 1. How is this divinity portrayed? Describe the divinity’s role within the myth. She was portrayed to be the goddess of love and beauty often shown smiling. She is the daughter of Zeus. Some myths also say they daughter of Uranus (Aphrodite, 2002). One of the more known and told myth is her helping Paris to abduct his love Helen of Troy. She was the goddess of love, lust, fertility and magic. According to Freyja (1996), she is believed to be the  daughter of the sea god Njord and the earth-goddess Nerthus. She had a twin brother named Frey. Some believe that she was married to Od and once he passed away she never married again and used her powers to have sex with gods, mortals, dwarfs, giants and dwarfs. Others say that she is the same person as Frigg who is wife to Odin (Freyja, 1996). 2. Is the divinity male or female? What function does this gender play? Aphrodite is female. Her gender function would be the sexual aspect of the myth surrounding her because she is known for seduction. Freyja was a female who was the goddess of lust and love. 3. Within the myth of origin, how does this divinity compare with other divinities? How does this divinity interact with or compare to divinities of the same gender and to divinities of the opposite gender? Aphrodite is one of the twelve great Olympians. Aphrodite was able to make all the gods and mortals fall in love or be overcome with desire, except Athena, Artemis, and Hestia (Aphrodite, 2002). She is known to have had many affairs against her mortal spouse with other gods and mortals. Aphrodite was equally quarrelsome and manipulative to both genders of divinities. If anyone wronged her she would make them fall in love with whomever or whatever she pleased. Freyja is one of the most respected of the goddesses. She is very well respected by the female gender of goddesses. She is the goddess of fertility and it was said that if a female wanted children they just needed to call on her and just being in her presence would become with child. The male gender is most lustful after Freyja. She was able to manipulate any male sexually. 4. What are the divinity’s attributes, such as divine powers or characteristics? What objects does the divinity possess, such as a weapon or animal, that assist him or her? She was able to make anyone fall in love. She could seduce anyone she wanted. She was able to encourage sexual desire, the care of women in child birth, magic, and she helped half the mortal heroes killed in battle to Valhalla. She was known to ride a board or be in a chariot pulled by cats. 5. Identify one character from contemporary culture that shares characteristics of each divinity and explain why you chose each character. What real-life ideals  does this divine role represent? How attainable are these ideals? For Aphrodite I think of the vampire characters from the television show and book series of True Blood. They are able to compel people to do whatever they want by either being lustful or on humans by hypnotizing them to do what they want. I think it shows that even in the beginning sex was still the key to being able to manipulate to get what you want. I don’t completely agree with these ideas. I think depending on who you are these ideals can be easily attainable. For Freyja I am going to use True Blood again but with the character of Sookie Stackhouse. She was lusted after from most males that came around her and she was magical because of being a fairy. Again, depending on the type of person you are some of the ideals are great. I know for women who have difficulty becoming pregnant would love to have her divine power of fertility. Scientifically there are ways to help women become pregnant but still not everyone is able to bear a child. Summary: Write a 150- to 350-word short essay addressing the following: Why do so many cultures have divinities in similar roles? I feel that as a human the thirst for knowledge is why many cultures have divinities with similar roles. I think that a lot of these mythological divinities were created as a way to explain why things are the way that they are. There as to be a reason why things are this way and before modern science finding the exact reasons were next to impossible. There are also people out there that believe the reason that all of these divinities are so similar is because they gods are actually aliens from other planets visiting our world. I don’t know whether any of the stories told have any semblance of truth, but it does make you think of the possibilities. In many religions they believe that there is only one god that created everything. There is no right or wrong answer at this point because I believe that until we find a way to travel back in time we can’t know exactly why these mythical divinities are so similar.

Liver cancer or ‘hepatocellular carcinoma’

Liver cancer or ‘hepatocellular carcinoma’ (or malignant hepatoma) is a malignant tumor that develops from the cells of the liver.   The tumor may develop from liver as the primary site, or from spread from other sites in the body (secondary cancer).   Primary cancer of the liver less frequently occurs compared to secondary cancer.   So far, in the year 2007, about 19, 000 new cases of liver cancer (both primary and secondary cancers) have developed in the year, and about 16, 800 patients have died from the disorder (NCI, 2007).   The type of treatment utilized and the outcome of the disorder depend on several factors including staging and spread of the cancer and the general health of the patient (and also other patient factors).If the disorder is detected and treated in the early stages, the outcome is usually better.   Some of the treatment methods recommended for liver cancer include surgery, chemotherapy, radiotherapy, liver transplantation, etc.   As th e current treatment available is rather ineffective in treating liver cancers, it is necessary that newer modalities be developed to treat the condition that would be both safe and effective.   Some of the newer therapies that are being researched for liver cancers include chemotherapy, chemoembolization, immunotherapy and radiofrequency ablation (NCI, 2002).Chemoembolization is a procedure characterized by mechanically or surgically obstructing the blood supply to the liver and then administering chemotherapeutic agents into the cancerous site so as to destroy them.   As the level of chemotherapeutic agents is high at the site, they are more capable of destroying the tumor.   Besides, the risk of side-effects are less, as the chances of the drug spreading in the blood is minimal.   Chemoembolization is usually performed to treat liver cancers that cannot be treated by surgery.   However, those patients in whom the liver cancer was advanced, spread to other sites of the bo dy, or developed associated renal failure, were excluded from the study.   Out of 908 patients who were initially identified, 112 matched the criteria and were a part of the study.   The drug frequently utilized is doxorubicin.The initial results that were obtained through the study were promising.   At present, no option is currently available to treat liver cancer.   Liver transplantation may have a few limitations.   Previously arterial embolization was utilized to treat liver cancer, but the survival rates in such cases could not be determined.   In this trial, the 112 patients were divided into 3 groups, and one received arterial emobolization only, the other received chemoembolization (arterial embolization and chemotherapy) and the third received conservative treatment.   The results obtained through chemoembolization were amazing.   21 out of the 40 patients treated by this method died (survival rate was 47.5 %).On the other hand, 25 out of the 35 patients tr eated through conservative methods died (survival rate 29 %) and 25 out of 37 (survival rate 32.5 %) died from receiving treatment through arterial embolization.   However, the complete or long-term results could not be obtained through this trial, as the initial results demonstrated that chemoembolization results were very beneficial.   The one-year survival rate for chemoembolization was about 82 % and the two year survival rate was about 63 %.   The one-year survival rate for arterial embolization was 75 % and two-year survival rate was 50 %.   The one year survival rate for conservative treatment was 63 % and the two year survival rate was 27 % (NCI, 2002).Radiofrequency ablation is frequently utilized to treat liver cancers that cannot be treated by surgery or other methods.   In this technique, a specialized probe that emits certain waves, and generates heat in the tissues is utilized.   The probe generates heat, and the cancerous cells are destroyed.   This proc edure is usually conducted under anesthesia (NCI, 2002).Pancreas cancer or ‘islet-cell cancer’ is a malignant tumor that develops from the cells of the pancreas.   It is a rare form of cancer, and in the US, in 2007, about 37, 000 new cases of pancreas cancer has developed and about 33, 370 individuals died from the disorder (NCI, 2002).   Pancreatic cancer may be difficult to be diagnosed early and treated problem, as the pancreas is a tiny internal organ and usually the condition does not produce any signs or symptoms.   Presently, surgery, radiotherapy and chemotherapy are utilized to treat pancreatic cancer.   Immunotherapy is still undergoing research for its effectiveness and safety in treating pancreatic cancer.A clinical trial was performed to determine the effectiveness of treating pancreas cancer with gemcitabine and chemoradiation.   The effectiveness of 5-fluroracil (an chemotherapeutic agent) and radiotherapy was compared to gemcitabine, along wit h 5-fluroracil and radiotherapy.   One out of every five pancreatic tumors can be treated by surgery.   Besides, the outcome following surgery for pancreatic cancers is very poor. The tumor can recur, thus reducing the survival rates.   Presently, in the US, chemoradiation is frequently utilized along with surgery in treating pancreatic cancers.   5-Flurouracil is frequently utilized in the chemoradiation.   As the chances of recurrences are still high with this modality, researchers have suggesting a clinical trial in which an additional chemotherapeutic agent is utilized along with the standard therapy.Gemcitabine was the drug selected to be utilized along with 5-flurouracil and radiotherapy, following surgery.   The main aim of the study was to demonstrate an improved outcome or a better survival rate following use of this combination in treating pancreas cancer.   About 442 individuals were selected for this trial and were divided into 2 groups.   The individuals of both groups had undergo surgery to remove the tumor and had to also undergo chemoradiation later.   In the first group, gemcitabine was administered before and after the chemoradiation, whereas in the second group, 5-Flurouracil was administered before and after the surgery.   Tumors that developed from the head and the tail of the pancreas were included in the study.   Gemcitabine used to treat pancreatic head tumors along with chemoradiation was had a survival period of about20.6 months.On the other hand, about 16.9 months was the survival period of those who received 5-Flurouracil.   The there year survival rate in those who received gemcitabine was about 32 %, and the three year survival rate in those who received 5-Flurouracil was about 21 %.   However, the risk of side-effects was higher in individuals who received gemcitabine.   These cells tended to destroy the blood cells.   Supportive drugs seemed to be more beneficial in treating gemcitabine-induced depr ession in the blood cell counts.   The study demonstrated that gemcitabine was more effective in treating tumors arising from the head of the pancreas after surgery, than 5-Flurouracil (NCI, 2006).Another study was conducted to determine the beneficial effects of gemcitabine along surgery, and surgery alone.   The study population (consisting of 368 individuals) was divided into two groups, the first group was administered gemcitabine following surgery, and the second group was treated with surgery alone.   The study demonstrated that recurrence rates of the tumor treated with gemcitabine and surgery was much better than those treated by surgery itself.   Recurrence occurred after 13.4 months in those treated with gemcitabine and after 6.9 months in those treated with surgery alone (NCI, 2007).References:National Cancer Institute (2002), Liver Cancer – Introduction.
