Hunan Resource-Does motivation come from within a person or is it the Essay

Hunan Resource-Does motivation come from within a person or is it the result of the situation - Essay Example However, motivation seems to arouse out of any of the discussed situations and it has to be considered that motivation cannot be seen in majority of the people as external or internal influence as a whole. Motivation can be classified into two types they are intrinsic and extrinsic motivation. Intrinsic motivation are engender within a person as a result of factors such as liability, autonomy to act, capacity to point out and apply the skills and an enthusiasm to face challenging works. Where as Extrinsic Motivation is created in people by outside influences such as rewards, backing, sponsorship, endorsement etc. However, most of the researchers observe Motivation as a behavioural intervention influenced wither by external forces or forces necessitated within the person. It is very important to analyse the reasons every action of human beings as that would help in giving the exact background for motivation. The reasons to get motivated could be sketched out at two levels they are, individual exhibiting certain activity in addition to how these activities came about. There lies a background for every action performed under motivation. The background of motivation might have come from the influence two forces that might be either a positive or a negative force. However, any kind of motivated action constitutes a goal within inside. For example, Toates’s [1980, 1986] observed motivation as involving a goal-oriented pattern, in which an organism is motivated to behave in a particular way; this behaviour might get changed completely after the organism achieves the goal. Therefore, any motivated behaviour is an influence of some conditions, which are required by the organism. Where as McFarland [1989] has a contradictory observation which says that motivation under the influence of a goal would continue even after the goal has been achieved. From this observation, it appears that McFarland’s notion about motivated actions results either from a

Does the current system of funding higher education support student Literature review

Does the current system of funding higher education support student academic learning - Literature review Example The authors have not shown the evidence of Universities that are struggling with issues of funding or the ones trying to cut their costs because of poor funding. One may not believe in the results of the study because the authors do not prove some of their claims such as the real reasons affecting universities funding and the level of investments other governments put in their universities (Connaway & Powell 2010, pp. 63-65). This may help in understanding whether indeed UK underinvests in their higher learning institutions compared to other countries. The data source is very reliable because the study has been carried out by a professional organization, Russell Group that entails several higher learning institutions. The group also contains academic professionals such as Professor Michael Arthur who is the chairman of the group (Russell Group 2010, pp. 45-50). There are also financial reports that have been used in carrying out the study. The sources used in the study are also relevant and are very reliable. The data used in the study are up to date because none of them is more than ten years old.

Using Tight-Binding Model Essay Example for Free

Using Tight-Binding Model Essay Abstract— In this study, using tight binding model a simple analytical approach has been proposed to investigate the energy dispersion of graphene under the conditions of different planner strain distribution. Here the change in the angle between the primitive unit vectors due to application of external strain has been taken into consideration to propose the approach. From our proposed model it is found that graphene under relaxed or symmetrical strain distribution is a zero bandgap semiconductor. However a band gap is opened as the asymmetrical strain is applied to it. It is seen that upto a certain level of strain (i.e. 12.2 % parallel to carbon-carbon bond and 7.3% perpendicular to carbon-carbon bond) the band gap of graphene increases and then begin to fall . So, four different assumptions have been made for angular change of primitive unit vectors for four different regions of applied strain (i.e. before and after the strain of 12.2 % parallel to carbon-carbon bond before and after the strain of 7.3% perpendicular to carbon-carbon bond). The result obtained in the present study are compared and found an excellent agreement, with more or less 96% accuracy with that of determined from first principle technique. Keywords—Graphene, planner strain, tight binding model, energy dispersion, band-gap. I. INTRODUCTION Graphene, a strictly two-dimensional material having unusual and interesting properties [1] is a rapidly rising star on the horizon of material science and condensed matter physics. It is a material of interest in semiconductor industry because of its exceptionally high crystal and electronic quality, excellent transport properties (i.e. high electron mobility [2] and high thermal conductivity), and as it is planner, it is capable of extreme device scaling comparing with silicon technology. However these excellent properties are associated with a major drawback; graphene is a zero bandgap semiconductor or semimetal [3]-[4]. For large scale manufacturing, the absence of bandgap is the most difficult engineering issue to solve. The zero bandgap revels that it is impossible to switch graphene based device from the conductive to the nonconductive state. So it can not be used in the logic circuit. As the zero bandgap property of graphene limits its application in practical fields, scientists are working to find out the methods to open the bandgap in graphene. To solve this problem several methods have been proposed, such as graphene nanoribbin using quantum confinement effect in its transverse direction [5]-[8], bilayer graphene introducing symmetry breaking between two carbon layers via an external electric field [9],[10] , by the process of doping [11]-[13] and by the process of external strain [14],[15]. To investigate the bandgap opening by the above methods, several techniques have been applied for calculating the band structure of graphene such as first principal calculation, tight binding modeling, k.p method etc. All of them are performed earlier using the software simulation or numerical techniques, which require a huge computational complexity and time consuming and need high capacity super computer. In our study we have proposed a simple analytical approach to investigate the energy dispersion of graphene under different planner strain condition. Using the proposed method the bandgap opening is calculated under the application of asymmetrical strain parallel and perpendicular to the carbon-carbon bond in graphene. The results obtained from the proposed method is compared with the result published by the first principle method and found to be in good agreement with more or less 96 % accuracy. II. METHOD Graphene is a honeycomb lattice of regular hexagonal structure. But it loses its regular hexagonal structural symmetry under uniaxial/shear strain. When planar stress is applied to graphene, the position of carbon atoms shift relative to each other. As a result the vector position of lattice point changes. To explain this, the angle between a1 and a2 is considered here as ÃŽ ¸ instead of assuming 60o which is true for ideal or relaxed graphene structure. The eï ¬â‚¬ect in the tight-binding Hamiltonian is that the parameters of tight-binding scales changes accordingly. The strained lattice structure of graphene is shown in Fig.1. We have used the simple nearest Neighbor tight binding model. Here each Carbon atom is ÏÆ' bonded with three of its nearest neighbor Carbon atoms. Fig.1 : The direct lattice structure of graphene under strained condition The primitive unit vectors can be represented by where The separation of the carbon atoms (A and B) can be represented by three vectors R1, R2, R3 From Tight-binding energy dispersion model the formula of energy dispersion is given by [13] (1) Where Here is a fitting parameter which is often called the nearest neighbor overlap energy or hopping integral. The value of varies from 2.7eV to 3.3eV. (2) This is the generalized equation for the energy dispersion of graphene. Here is the angle between the primitive unit vectors. For the unstrained or relaxed condition, the value of the angle = 60o. In this case the Ï€ bands overlap at direct point or K point of the two dimensional brillouin zone. (a) (b) Fig.2(a) energy dispersion of relaxed graphene and (b) the corresponding brillouin zone. We have investigated the electronic structure of graphene under different planar strain distributions by the tight-binding (TB) approach. The graphene has been strained in three different ways [12]. These are : (i) symmetrical strain distribution (keeping the hexagonal symmetry unchanged) as shown in fig. 3.1(a) , (ii) asymmetrical strain distribution parallel to C-C bonds as shown in Fig. 3.1(b) , (iii) asymmetrical distribution perpendicular to C-C bonds as shown in Fig.3.1(c). Fig 3(a) Graphene system with symmetrical strain distribution, (b) asymmetrical strain distribution perpendicular to C-C bonds, and (c) asymmetrical strain distribution parallel to C-C bonds. Corresponding primitive cells in black, reciprocal lattices in green dashed and Brillouin zones in green grey are illustrated below the deformed lattices. Γ, K, M, R and S are the high symmetrical points. Lx and Ly are the half of the diagonal lengths of the primitive cells in parallel and perpendicular direction of the carbon-carbon bond. As the strain is applied to the graphene, it causes the deformation of the regular hexagonal structure of it . It also causes the deformation in the primitive unit cell. If the strain is symmetric then the band property of the system does not change but for asymmetrical strain , the band property of the system changes due to symmetry breaking. When an asymmetrical strain parallel to C-C bond is applied, it causes a deformation in the primitive unit cell. This deformation is taken as a change in angle between the primitive unit vectors. Here the strain is applied upto 12.2 % and it is seen that with the increase in strain the angle between the primitive unit vectors is reduced by following a 3 degree polynomial with respect to Lx and Ly(where Lx and Ly are in nanometer). The equation of is (3) This value of is then put in equation (2) to calculate the band gap under different strain distribution . It is seen that up to Ly =0.2396 nm band gap of graphene increases then the bandgap begin to fall . For this region the assumption of is different and it is, (4) In case asymmetrical applied strain perpendicular to C-C bond , up to 7.3 % strain the angle between the primitive unit vectors is increased by following a 2 degree polynomial with respect Lx and Ly. The equation of is, (5) Now up to Lx = 0.1323 nm band gap of graphene increases and then the bandgap begins to fall. For this region the assumption of is, (6) III.RESULT Asymmetrical strain distribution results in the opening of the bandgap between the maximum of the valance band and the minimum of the conduction band in graphene. When an asymmetrical strain parallel to carbon-carbon bond is applied, Ly increases. Then for the system in order to come back to its lowest energy, Lx decreases during the structural relaxation. Due to change of Lx and Ly, the angle between the primitive unit vectors decreases and causes the symmetry breaking. This angular change is taken as the parameter of deformed primitive cell to calculate the electronic structure of graphene. For example, for Ly = 0.2196, 0.2236, 0.2396, and 0.2436 nm the corresponding optimized values of Lx are Lx= 0.1228, 0.1224, 0.1217 and 0.1216 nm. Then from our proposed model the corresponding angle between the primitive unit vectors are =59.47o, 58.91o, 54.79o and 57.75o. The corresponding electronic structure or band diagrams are shown in fig.4 with the extended view at K point (a) (b) (c) (d) Fig.4 Extended view of bandgap opening for (a) Ly=0.2196 nm and Lx=0.1228 nm (b) Ly=0.2236 nm and Lx=0.1224 nm (c) Ly=0.2396 nm and Lx=0.1217 nm (d) Ly=0.2436 nm and Lx=0.1216 nm. Similar behavior is obtained in the graphene system, when asymmetrical strain perpendicular to carbon-carbon bond is applied. In this case for example for Lx =0.1268, 0.1292, 0.1353 nm the corresponding optimized Ly are Ly=0.2126, 0.2120 and 0.2105 nm and the corresponding deformed angle are = 60.52o, 61.05oand 60.38o. The opening of bandgap corresponding to these deformed angle are shown in fig.5 (a) (b) (c) FIG.4 EXTENDED VIEW OF BANDGAP OPENING FOR (A) LX=0.1268 NM AND LY= 0.2126 NM (B) LX= 0.1292 NM AND LY=0.2120 NM (C) LY=0.1353 NM AND LX= 0.2105 NM . These results revels that the zero bandgap or semi-metallic behavior of graphene sheet gets modified or a bandgap is opened when asymmetrical strain is applied to it. Now the question is what is the reason behind this? We know that planner graphene consists of strong bonds and delocalized pz electrons. Here orbitals are formed by overlapping the pz orbitals of the carbon atoms in the hexagonal lattice. These and bands touches each other at the K point causing zero bandgap. When the strain is applied the carbon-carbon bonds of graphene get elongated. Due to this elongation of carbon-carbon bonds, the electron clouds get localized on the corresponding carbon atoms. Therefore a restriction is imposed on movement of the electrons which causes the opening the bandgap at the K point. In this way, under strained condition, graphene loses its semimetal characteristics and turns into a direct bandgap semiconductor. IV.COMPARISON WITH ESTABLISHED METHOD: In this study, we have calculated the band gap of graphene under the application of asymmetrical strain by an analytical approach. The calculated value is found to be in great agreement with the measured value obtained by first principle calculation [14]. It is found that in case of asymmetrical strain distribution parallel and perpendicular to C-C bond, the percentage of error is more or less 4 % for most of the data which is shown In this study an analytical model has been proposed for investigating the energy dispersion of strained graphene under the distribution of the planner strain in parallel and perpendicular to carbon-carbon bond. Using the proposed model the energy dispersion for different planner strain has been calculated. From our study it is seen that for relaxed or symmetrically strained graphene, the band gap of the system is zero. When asymmetrical strain parallel or perpendicular to carbon-carbon bond is applied then a finite bandgap is opened. And it is also seen that tuning the percentage strain, the band gap can also be tuned. Here it is also seen that comparing the perpendicular strain, parallel strain parallel to the carbon -carbon bond more induces more bandgap. Finally we have compared our results with the results obtained from the established method and found good agreement with around 96 % accuracy. References [1]A.K. Geim and K.S.

Grounded theory in research

Grounded theory in research Evaluate the contribution of grounded theory, as an approach to data analysis Introduction The concept of grounded theory is from the Glaser and Strauss research in 1967. In 1960s, they made a research for medical personnel to deal with an imminent death of the patients field observation in a hospital, and then discovered and developed the grounded theory. In this essay, I will evaluate the grounded theory in 5 parts. The first part is the characteristics of grounded theory; the second part is the procedure of grounded theory; the third part is comparison with other types of research methods and the forth part is the contribution of grounded theory research in management field, and the last part is the future of grounded theory. 1. The characteristics of grounded theory Some perspectives of grounded theory In Suddabys (2006) view, the grounded theory can be described as: â€Å"Grounded the ­ory is best understood historically. The methodology was developed by Glaser and Strauss (1967) as a reaction against the extreme positivism that had per ­meated most social research.† (Suddaby 2006, p.633) And Gephart (2004) points out: â€Å"Glaser and Strauss (1967) proposed grounded theory as a practical method for conducting re ­search that focuses on the interpretive process by analysing the â€Å"the actual production of meanings and concepts used by social actors in real settings† (Gephart, 2004, p.457). And another view is Glasers perspective (1992, p16), he argues that: â€Å"The grounded theory is a general methodology of analysis linked with data collection that uses a systematically applied set of methods to generate an inductive theory about a substantive area.† Grounded theory research method is a type of qualitative research which is based on induction. It used in many sociological research areas such as education, religion, and many others. Zhigang (2007) argued that the method is characterized by extracting the theory from the phenomenon to create or enrich existing theoretical system. In the view of Layder (1993), Grounded theory method is a process of generating a theory, which including constant comparison, thinking, analysis and transformation of information. The characteristics of emphasis on information and more interactive approach, which makes the researchers collect data by making use of a continuous and intimate interactions of the parties and events. In summary, in the first place, according to Zhigangs perspective,(2007) the grounded theory is a bottom-up approach to establish substantive theory, which is finding the core concepts reflects the social phenomenon based on systematical data collection, and then generate the relative theory through the links between these concepts. Secondly, grounded theory must be supported by empirical evidence, but it is not the main feature of grounded theory, the main feature is that it generates new theory or idea abstracted form the experience and data analysis. Lastly, in philosophical ideology, grounded theory approach is a paradigm based on the post-positivist, which emphasize on falsifying current theory which has been constructed. The comparative analysis the core of data analysis of grounded theory Strauss Corbin (1998) pointed out that the grounded theory emphasizes on development of the theory, but also the theory is based on the data collection of realities, and continuing data analysis through the comparison. The strategy of comparative analysis usually used in sociology research. In grounded theory, it is a very important process. Glaser and Strauss (1967) argued that it should be first contrasted the use of the method with certain other users in the research process, and then define and describe what type of theory be created through comparative analysis. The purpose of comparative analysis, as a strategic method for generating theory, is to obtain the accurate evidence, which is the difference between establishing theory and verifying theory. The evidence collected from some comparative groups, which is used to examine whether the original evidence was correct. The characteristic of comparative analysis for establishing theory or concept puts a high emphasis on theory as process. In other words, theory is not perfected; it needs develop continuously through comparative analysis. Glaser and Strauss (1967) believed that theory renders the reality of social interaction and its structural context as a process. The coding Coding is a key element of the data analysis in grounded theory. BaiKai and YuanBo (2009) argued that the encoding is the usually used technology in the qualitative research which is entirely different from quantitative research. In qualitative research, the purpose of coding is not counted, but rather deconstruction of information to form the concept. They would be re-arranged in different categories, in order to promote the comparison of information and proposition of theoretical concepts in one category. Zhigang (2007) points out that the effective use of the grounded theory primarily depends on the following two aspects: on the one hand, the researchers should make an effort to choose a meaningful direction or area of research. It is difficult to identify the gaps that may exist in the theoretical proposition; On the one hand, the researchers should pay attention to data collection and collation, and propose some theoretical assumptions and refining the new conclusions in accordance with the principles, steps and techniques of the grounded theory. 2. The procedure of the grounded theory In Strauss and Corbins view (1998), it is important that focus mainly on the process. They believe that the process is more important as describing and coding everything which is continuously changing. The process of grounded theory research made based on the view of Pandit. N (1996) Source: Pandit. N (1996) The Creation of Theory: A Recent Application of the Grounded Theory Method As can be seen clearly, there are mainly 3 phases in the process of grounded theory research design phase, data collection phase and data analysis. The whole process is started at review of technical literature and finished at reaching closure, but it is need to note here is that if the result is theoretical saturation after the theoretical sampling step, it should be restarted the second step selecting cases. According to the Suddabys view (2006), There are 2 key points in the method which described by Glaser and Strauss (1967) â€Å"constant comparison,† and â€Å"theoretical sampling,† in which data are collected and ana ­lysed simultaneously, and â€Å"theoretical sampling,† in which decisions about which data should be collected next are determined by the theory that is being constructed. Therefore, the most important steps in the process are data analysis and theoretical sampling, which are the key difference in contrast with other research methods. 3. Comparison with other methods of qualitative research Grounded theory and other various ways in social research have different advantages and disadvantages. Possibly different types of methods can be used in different areas. Researchers select different research methods, could means that they have different research ideas and objectives. At the same time, selection and use of methods could more depend on the topic or the attribute of research. The necessary requirement of obtaining the valuable research findings is the appropriate combination between objectives and methods of the research. Comparison with Hypothesis Testing The Hypothesis testing method is different from the Grounded theory method. The definition of Hypothesis testing can be described as: â€Å"Hypothesis testing research investigates a phenomenon in terms of a relationship between an independent and dependent variable, both of which are measurable numerically. This relationship is called a hypothesis. The aim of the research is to test whether the hypothesized relationship is actually true, using statistical methods.† (Auerbach and Silverstein, 2003, p.3) Although hypothesis testing and grounded theory are good research methods to do the research in some areas, there are some differences between them. The hypothesis testing method is mainly different from the grounded theory in the process of building theory. In hypothesis testing method, the hypothesis or idea has been generated first. Researchers can make hypothesis without any evidence, then they will look for the evidences or collect data and information to support their hypothesis or idea. In contrast, grounded theory is an inductive method which focuses on the discovery and does not rest on hypothesis testing but on building hypotheses according to the data and relative information. Suddaby (2006) point out: â€Å"Glaser and Strauss rejected positivist notions of falsification and hypothesis testing and, instead, described an organic process of theory emergence based on how well data fit conceptual categories identified by an observer, by how well the categories explain or pred ict ongoing interpre ­tations, and by how relevant the categories are to the core issues being observed.† (Suddaby, 2006, p.634) It is clear that the hypothesis testing a grounded theory would be used in different fields, such as the hypothesis could be used for working out the mathematics problem and grounded theory could be used in the research in the social areas. Which method can be chosen for research depends on the objectives of the research. Comparison with Ethnography Creswell (1998) argued that ethnography involves prolonged observation of the group, typically through participant observation in which the research is immersed in the day to day lives of thepeople or through one on one interviews with members of the group. Clearly, the ethnography method could be more used in the research of human, culture and language etc. From the view of Creswell (1998, p148), the following table can describe the differences between grounded theory and ethnography in data analysis process. Data analysis and representation Grounded theory Ethnography Data managing Create and organize files for data Create and organize files for data Reading, Memoing Read through text, make margin notes, form initial codes Read through text, make margin notes, form initial codes Classifying Engage in axial coding Engage in open coding Analyse data for themes and patterned regularities Interpreting Engage in selective coding Develop a conditional matrix Interpret and make sense of findings Representing, Visualizing Present a visual theory Present propositions Present narrative presentation augmented by tables, figures and sketches Source: Creswell, J. (1998) Qualitative inquiry and research design: choosing among five traditions As can be seen clearly, the most difference between grounded and ethnography is from classifying step to visualizing step. The 3 core coding steps play an important role in the data analysis of grounded theory, which make the grounded theory can be developed through the constant comparison. And also it is one of the advantages of grounded theory in contrast with other qualitative methods as an approach to data analysis. Mello and Flint (2009) believe that the grounded theory primarily uses interviews, but also uses observation and documents analysis like an ethnography method. It differs from an ethnography method because of its purpose, which is to build theory. Like many other interpretive qualitative approaches, grounded theory has helped other disciplines open up fruitful new avenues of research. Hammersley (1990) argues that much ethnography places emphasis on the ‘description as an important purpose of research, there are other strands that focus on a form of ‘theoretical description. However, while Glaser and Strauss think that grounded theory is related to the wider context of qualitative analysis and method. The grounded theory approach is highly distinctive and unlike other types of qualitative methods. 4. Grounded Theory in management research It is no doubt that the grounded theory can be used in a wide range of research such like nursing, business and management, mathematics and many types of sociology. Then, I will talk about the contribution of grounded theory focus on the business and management area. Firstly, the following table gives some examples of the grounded theory used in management research. Examples of grounded theory in management research Example references Senior executives and IT Systems development Managing understanding in orgnisations Organisational culture Staff perspectives on work Retailer response to manufactures low-cost programmes Rural women entrepreneurs Competitive strategy and manufacturing Process technology Building co-operation in competitive industries Consumer behaviour Advertising and mass media Marketing Career development Electronic data interchange Leadership in organisations Strategic alliances Ideal business images for women Tourist behaviour Employment outcomes Seeley and Targett (1997) King (1996), Calloway and Ariav (1995) Brown (1994, 1995) Turner (1981, 1988) Clegg et al.

(2002) Grounded Theory: A Practical Guide for Management, Business and Market Researchers From the table above, it is obvious that the grounded theory can be used in many researches about business and explores a wide range of management problems. â€Å"These situations merely serve to demonstrate the transcending nature of grounded theory and its potential for application in the field of management research.† (Goulding, 2002, p.51) Taking the marketing field as an example, â€Å"grounded theory has begun theoretical development in the areas of the creation of a market oriented firm, moving away from previous research that merely described what a market oriented firm looks like.† (Gebhardt, Carpenter, and Sherry, 2006, citied in Mello, and Flint (2009) A Refined View of Grounded Theory and Its Application to Logistics Research p.109) 5. Grounded theory in the future What grounded theory will happen in the future? It is no doubt that the grounded theory will be used for doing research in the wider range of fields. Increasing researchers will choose the grounded theory as the first choice. Youhui (1996) think that one of the characteristics of grounded theory method is that the discover believe that it is necessary to generate theory in the research of sociology and both data analysis and theory building should be focused in qualitative research and any other research methods. Therefore, the grounded theory method is ideally suited to the areas such as: the existing theoretical system which is not perfected, the phenomenon which is very difficult to effectively explain, or the new areas and phenomenon which has no systematical theory currently. About the Justifying Grounded Theory in the future, Glaser described it as: â€Å"The future will bring less need to legitimize grounded theory; hence, there will be less need to justify using it. Now, many researchers have to explain it and argue for its use. Its future portends that grounded theory will be as accepted as are other methods (e.g., surveys) and will require little or no explanation to justify its use in a research project.† (Glaser, B.G. 1999, pp.845) Charmaz (2005 citied in Denzin, N.K. and Lincoln, Y.S. (2005) Handbook of Qualitative Research) believe that a major strength of the grounded theory is that they provide tools for analysing process, and these tools hold much potential for studying social justice issues. She also believed that coding practices can help us to see our assumptions, as well as those of our research participants. Rather than raising our code to a level of objectively, we can raise questions about how and why we developed certain codes. Grounded theory has its own advantages, it is to believe that grounded theory will be developed deeper and suitable for the research, Charmaz (2005 citied in Denzin, N.K. and Lincoln, Y.S. (2005) The SAGE Handbook of Qualitative Research 3rd ed.) write that: â€Å"As its best, grounded theory provides methods to explicate an empirical process in ways that prompt seeing beyond it. By sticking closely to the leads and explicating the relevant process, the researcher can go deeper into meaning and action than given in words. Thus, the focused inquiry of grounded theory, with its progressive inductive analysis, moves the work theoretically and covers more empirical observations than other approaches. In this way, a focused grounded theory portrays a picture of the whole.† (Charmaz, 2005, pp.529) Conclusion To sum up, the grounded theory has a wider use range than other methods. For those social areas which lack current theory and some phenomenon which lack enough evidence and explanation, the grounded theory method is an effective analytical technique as an approach of data analysis. This method not only can help researchers to use inductive methods to abstract the basic theory from the phenomenon in the research, but also it is a good way to build and develop the theoretical system gradually to achieve the combination with the current theory effectively. There are many contributions of grounded theory in many different areas such as business, education, medicine and other many others. In terms of many advantages and characteristics of grounded theory, we believe that it will be use in more range of social research as an approach to data analysis and developed more to be accepted by more researchers.

Against School Dress Codes and Uniforms Essays -- Clothing Clothes Sch

The Debate Between School Dress Codes and Uniforms The debate over school uniforms and dress codes has been going on for years and is still widely debated and talked about in the education system. Each side of the argument has many supporters. There are many pros and cons to each side so it is hard to really know what the right choice is. In Three Cups of Tea written by Greg Mortenson and David Oliver Relin education is the main focus of the book. Although most of the book takes place half way across the world many topics are relevant to the school systems today in America. In the book the girls received, â€Å"crisp new school uniforms neatly folded inside its cellophane wrapper† and they are completely overjoyed to hold their first set of new clothes ever (194). The history of the topic helps bring light to the decisions that are being made in schools, as well as discussing pros and cons associated with the implementing uniforms or not. Both sides to the argument bring valid points to the table and must be heard by e ducators, parents, students and government officials in order to come to the correct decision on whether school uniforms and dress codes should be implemented in Americas school systems. School uniforms and dress codes should not be placed the school system because it violates the first amendment and uses funding that the school systems do not have available to them. Many people think that school uniforms are a thing of the past, however this is only partially true. According to Wendell Anderson research analyst and writer for the ERIC Clearinghouse on Educational Management, says that in the 1950s and 60s â€Å"dress codes prohibited girls from wearing slacks [and] stipulated the length of girls’ skirts.

Public Relations Issues :: essays research papers

As the public relations manger I have been asked to outline issues with regards to the working conditions within this firm. I have had concerns about a variety of areas and I wish to address you all on them. As new employees you are required to do the same job as others in the same position for the same amount of money. Because you are new does not mean you should be paid any less than some one who has been working there the longer than you. An award is a document that sets out the rights and responsibilities of employees who work in a particular type of job, regardless of who they are employed by. An individual employer gets no say in an award once it has been put in place. The award is designed to protect the rights of employees. The system of awards developed from the English system in the 19th century when protection against employers who would do the wrong thing by employees when exploited workers are being paid a very low wage and are expected to work long hours. An Award wage is in place to protect you as employees from being paid less that of what is required. Awards set out the minimum wage and conditions of employment for specific employees. These awards can include things such as the minimum rates of pay and allowances, overtime, shift penalty and other penalty rates, how If the many hours of work are required and leave provisions such as sick leave or personal leave. The protection for employees given by awards is good, but it is not always a strong form of protection when put to work. Employees might find that their employer is underpaying them. In other words the employer is paying them less than they are entitled to under the ward which is illegal. Though many employees are often unwilling to do anything about it because they think if they do complain their employer will make it harder for them at work or find a way to get them dismissed which is no exception. The employers also have many rights just as you the employee does. Some of the employers rights include. Paying the correct wages and deducting tax from employee’s wages, Contributing to the employee’s superannuation. The superannuation guarantee has been in place since 1st of July 1992 and it requires employers to provide sufficient superannuation support for their employees.

‘The Great Gatsby’ is an interesting novella about the intertwining lives of those who are striving for the artificial American Dream

‘The Great Gatsby' is an interesting novella about the intertwining lives of those who are striving for the artificial American Dream. It is a story of contrasts: the rich and poor, the loved and unloved and the different aspects of society that are shown in this passage through dramatic symbolism and highly structured parallels. The parallels between the first and third chapters show rich and privileged lifestyles, first the life of Tom and Daisy then Gatsby's party. This passage is conveniently placed between the two to show the â€Å"real world† of the likes of Wilson and other â€Å"sickly†, â€Å"ash-grey men†. It helps us to understand Myrtle as a character. Her hopes and dreams to get away from this life that is a constant struggle. This also describes the way both Gasby and the author Fitzgerald lived as children, and therefore their reasons to follow their dreams and aspire to something better. These parallels are a typical example of how novella's are tightly structured. We are led to believe that Nick is the narrator of this passage, however Nick has never been to the area before so when it is described cinematically and we are told of how passengers on trains wait â€Å"for as long as half an hour† we realize Nick could not have previously known this and therefore it is told to us directly by Fitzgerald. This poses a problem because the reader knows and trusts Nick but not Fitzgerald so he manipulates the reader into thinking it is Nick so that we believe him. The drawbridge in the final paragraph symbolises how it is not easily to get out of the Valley of Ashes, reflecting how it is not easy to get out of a hard life and achieve the American Dream. Myrtle tries hard in the novella to do this, and for a while Gatsby does, which is one reason why we see him as a hero. Images of how the American Dream has died are shown in the â€Å"Valley of Ashes†. Ash is symbolic of death, as in â€Å"ashes to ashes, dust to dust†, a traditional phrase at funerals. In the Valley of Ashes everything is bare, dull, lifeless and dead. It is based on the Corona Dump in Queens, which Fitzgerald famously resented on sight. He also nicknamed the Corona Dump the â€Å"Valley of Ashes†. ‘Of Mice and Men' by John Steinbeck also mentions â€Å"ash pile† in the beginning of the novel about the struggle to reach an American Dream. Death is represented by ash later on in the novella when Gatsby is described as â€Å"ashen† after his death. He was born in ash and died as ash. His life started as a struggle in a poor area and although he died wealthy, he still died in ash. The dust which â€Å"drifts endlessly† could symbolise shards of the American Dream which are helplessly out of reach of the people who live here, but drift in the air to taunt them about what they could become. The empty valley of ashes reflects the empty lives of the people who live in it. â€Å"Occasionally† grey cars enter the â€Å"desolate† area, so they made occasional breaks in the emptiness. This is parallel to the empty lives of the inhabitants. Occasionally there is a break and they have visions of hope, such as Myrtle's aspiration to be rich in a life with Tom. This also reflects Gatsby's funeral which was empty apart from Nick and Gatsby's father. Fitzgerald thought of himself as a failure as his writings were not particularly successful during his lifetime, so he may have had himself in mind when describing these lives wih failed hopes and empty dreams. This passage also gives the impression that morality in the modern world has died. As its place in the novel, the passage is between Nick meeting Tom's wife and Tom's mistress, his situation proves Tom's lack of morals. The passage is the no-mans land between the two women. Nick, the only character proved to have morals in the novella, is introduced to the â€Å"eyes of Doctor T. J. Eckleburg† on an advertising board. The â€Å"blue and gigantic† eyes look down over the Valley of Ashes and this could be interpreted as God watching over his world. This idea is later strengthened when Wilson looks up at him and refers to him directly as God. Eckleburg, however, wears â€Å"enormous yellow spectacles† and also his vision is clouded with dust, and as we see God as our ‘all-seeing' moral guide, this could symbolise a lack of moral guidance in the jazz age of the 1920's. There is no-one to show people the way. Doctor T. J. Eckleburg is another good example of sym bolism in the passage. Sight is the link between the three paragraphs of this passage. It moves from sight being obscured by ash and dust, to clarity of sight which is implied by how suddenly the narration switches from grey and dull areas to the bright colours blue and yellow on the ‘all-seeing' symbol of T. J. Eckleburg, to train passegers observing what's going on. These are the three ways that Fitzgerald wants us to see the characters, from all angles. An example is how we learn about Gatsby and his life becomes clearer to us by the end of the novella. Life and death are symbolised by T. J. Eckleburg and ash in this passage and they are described intertwined so as to make it impossible to work out where one ends and another begins. However, mostly this passage is mostly about death: the death of morality, the American Dream and the death of hope. Without these three things, the lives of the people in the area were totally meaningless. Tony Tanners' quote about how the narrator respnds reflects the readers response to this realisation. â€Å"Nick cannot tolerate the thought of confronting a reality that is merely poor and bare, dust-covered and wrecked. There must be more than that.†
