The creation and consumption of Pornography objectifies women Research Paper

The creation and consumption of Pornography objectifies women - Research Paper Example To objectify means to present or regard as an object. While the pornographic industry has presented women as objects, it is equally guilty of degrading women and belittling their status in the eyes of men, especially those who are subscribers to pornographic magazines. Back in the days before pornography was so rampant, social attitudes towards sex were that it was a deeply personal subject and public displays and discussions about it were strictly taboo. Then came the Golden Age of Porn, a period lasting from the 1960s to the 1980s, in which there was a movement for sexual liberation following the Flower Power revolution. ‘Make Love, Not War’ was a popular message on T-Shirts from the Woodstock era. It opened the way to live-ins and the love-child. Opportunists like Hugh Hefner and Larry Flynt saw a quick and easy way to make big bucks out of the changing scenario. Playboy was launched in 1953 and Hustler in 1974, making both of them millionaires in the process. Although there have been efforts to suppress pornography and the victimization of women from many quarters, the foremost objections coming from religious leaders, feminists and moralists, the evolution of the Internet, the profusion of media types and the effects of pornography’s rich contribution to the media industry have been some of the reasons even the Government is reluctant to take steps to stop this billion dollar industry (Schlosser, ‘Reefer Madness’, 32). It has been estimated that on the average, 70 percent of men between the ages of 18 and 34 years visit a pornographic website, a store or a brothel in a typical month. The sad thing is that the profusion of pornographic sites on the Internet has brought this evil right into our homes without much public outcry at all. Try as we might, pornography will prevail. The outrage is that not only do pornographic magazines demean women, they also help create sex offenders and weirdos by

Human Resource Management 2 (MASTER) - Essay Example There are some who argue against peternity leave as being a valid HR benefit, however despite these criticisms, there is enough evidence available which illustrates that peternity benefits could be used to reduce turnover and satisfy employees’ needs both psychological and sociological. This report offers considerably more advantages to peternity leave policy implementation than disadvantages. Reward employees for accomplishing organisational objectives, as part of a performance management package, by offering additional peternity leave days-off in the event of future issues with qualifying pets. type of leave in an effort to improve retention and also enhance the public reputation of the company while also satisfying a variety of stakeholder interests. This has made peternity leave a potential topic of interest for improving the business’ human resources policies regarding employee benefits. The purpose of this report is to identify the viability of establishing a similar peternity leave policy at the company in an effort to enhance business reputation and employee retention. The impact of establishing such a new benefits policy on total organisational performance is the main focus of this report. The report consulted with a wide variety of case studies and secondary literature in the domain of human resources management and psychology to uncover whether establishing a new peternity policy would be of long-term value to the company. Virgin Mobile Australia has established its own version of peternity leave to include specific criteria for being able to take advantage of this policy. First, it is only available to employees when they are introducing a new puppy or kitten to the family household and the pet must not be older than 10 weeks (Moran, 2009). Additionally, this leave does not apply to rats, fish or other pets such as snakes and iguanas (Moran). It is apparent that Virgin Mobile Australia recognises the

Research Methodology Chapter | Qualitative Research

Research Methodology Chapter | Qualitative Research The aim of this chapter is to undertake a critical review of the research method used, including an awareness of alternatives approach and the basic research question is discussed. This chapter describes the approach that the researcher undertake in order to carry out the research needs of this paper. The research objectives are to examine the marketing strategies, how a company creates the good relationships between customer and the service provider in telecom sector. This chapter plays an important role as a part of dissertation because it discusses the methods available to the researcher and justifies the method chosen. Its implication lies on the fact that it supports the findings of the researcher by validating the selected technique as appropriate for the situation. In the first stage of this chapter researcher defined the methods and techniques in detail and in the later part of this chapter the reason has been provided which research method was suitable for this study of rela tionship marketing. A research methodology is a method for how research study is to be carried. It helps the researcher to answer questions authentically, completely and precisely. Research methodology refers to the procedural framework within which the research is conducted (Remenyi et al., 1998). There are many factors to be considered when choosing an appropriate research methodology, with the topic to be researched and the specific research question being primary drivers (Remenyi et al., 1998). (Kumar, 1999, Blaxter, Hughes Tight, 1996) argue that the basic characteristics of study are intend to be, a designed, careful, methodical and dependable means of finding out or deepening understanding. McGrath (1982) posit that the choices make it apparent that there are no perfect solutions, only a sequence of compromises. Patton (1990) expresses the same view: research, like diplomacy, is the art of the possible. Noteworthy, however, a methodology must not, regardless of all other conditions, dominate the research procedure. A preliminary framework for this study was developed from the literatures about the relationship marketing, the role of CRM, Customer loyalty and information technology to create relationships (Hagel and Singer, 1999; Peppers et al., 1999). This framework has the three usual parts of a system: inputs, processes and outputs. That is, inputs of Internet information about customers are processed and converged with a firms customer databases, to produce a series of strategic outputs such as improved customer relationship management. As a result of the diverse ways of understanding relationship marketing, no set of best practice has been promoted although several approaches nevertheless have been proposed (e.g. DeSouza, 1992; Rosenberg and Czepiel, 1984; Stone and Woodcock, 1995). It has even been suggested that no guidelines exist that guarantee an effective design, implementation, monitoring and measurement of a relationship marketing programme (Grande, 1996; Pinto, 1997). For example, when the term relationship marketing is used in so many different ways that confusion sets in (Palmer, 1998, p. 106) is it then not possible to identify activities that, if practised, can be presented as substantive evidence of the practice of relationship marketing itself? Also, how are programmes of relationship marketing implemented and subsequently monitored (Cravens, 1998; Gummesson, 1998)? Finally, Gummesson (1997) notes that the measuring of returns on relationship marketing is still in its infancy so in what way(s), if at all, are returns on relationship marketing measured? 3.2 Research Paradigm Research can be conducted in a number of ways. It is important to determine which paradigm is most suitable for this research. Paradigm offers a framework comprising an accepted set of theories, methods and ways of defining data (Hussey Hussey, 1997). There are two research paradigms exist: Positivist and phenomenological. The principles of these two paradigms will be discussed in terms of their relevant strength and weaknesses in order to justify the researchers choice. 3.2.1 Positivism Paradigm Positivism is that the social world exists externally and its properties should be measured through objective methods rather than subjective methods through sensation or intuition (Smith, 2002). Positivists emphasize on highly structured methodology and to develop quantitative data for an appropriate set of preconceived hypotheses is to be tested. They consider objective criteria rather than human beliefs and interests to determine the study area. (Smith, Thorpe lowe, 2002; Saunders, Lewis Thornhill, 2003). According to Hussey (1997) research undertaken in this way will be precise, objective and the process of researching will have no affect on what is being researched. This type of research is performed in order to invent, confirm or reject an accepted theory. A key criticism of this approach is it is difficult to treat people as being separate from their social contexts and they cannot be understood without examining the perceptions they have (Hussey Hussey, 1997). However, consistency is high with generalisations being possible from data collected from a sample or population. In testing a theory, research will either attempt to prove or disprove a theory. Positivists emphasize on highly structured methodology and to develop quantitative data for an appropriate set of preconceived hypotheses is to be tested. They consider objective criteria rather than human beliefs and interests to determine the study area. (Smith, Thorpe lowe, 2002; Saunders, Lewis Thornhill, 2003). 3.2.2 Phenomenological Paradigm Phenomenological (interpretive science) investigation uses qualitative and naturalistic ways to inductively identify individual experience in context-specific situation. This approach attempts to recognize and describe a phenomenon, rather than exploring for exterior reason or primary laws (Easterby-Smith, 1991; Remenyi et al., 1998). Because of criticism on the positivist paradigm, the phenomenological paradigm was developed. According to Bryman(1999) understanding human behaviour from the participants own frame of reference. The main advantage of using the phenomenological paradigm is its ability to enable the researcher to elaborate and embrace several different themes simultaneously to achieve a greater understanding of what is occurring in the phenomena. The major disadvantage of this paradigm is that the reliability is very low. Thus the generalizations to a wider population cannot be made to any degree of accuracy. 3.3 Research Methods In the perspective of data collection, Jackowicz (1995) defines method as a systematic and orderly approach taken towards the collection of data so that the information can be obtained from those data. One of the most difficult tasks of a researcher is to turn the data into information. To explain the difference between data and information, the main characteristics of data is that it is raw, specific, undigested and therefore largely meaningless; information in contrast of data is what comes out when data have been arranged in such a way that uncertainty is lessened, queries resolved, and questions answered. To get data to generate literature review, two paths are followed one is the theoretical concepts, and the other is investigation of secondary sources of data within telecom industry. The literature review is designed to give critique of the area of relationship marketing. Its aim is to create a background for the primary and secondary research. Within the methodological field in marketing research the two wide ways of quantitative and qualitative work have fascinated both appreciation and disapproval (Birn et al., 1990; Goodyear, 2000). Research can be classified into two dissimilar types Quantitative Method. Qualitative Method. In quantitative method data is gathered and analysed using statistical tools. The data is often gathered through surveys, interview, questionnaires, etc. Edem (1994) argues that quantitative methodology validate research findings and gives the researcher a security of completion or reassurance in contributing to the development of knowledge. Bryman (1993) condemns quantitative research methods for their obvious method and linearity, and their lack of concern over the influence of resource limitations. Gable (1994) considers quantitative research to be relatively weak when used with the objective of discovery and during data collection. 3.4 Qualitative Research Method The principal consideration is to identify research methods that increase ones understanding of an issue rather then build upon existing theories and test relevant hypothesis. This position is supported by Bell (1993), according to Bell Researchers who adopt a qualitative perspective are more concerned to understand individuals perceptions of the world. They seek insight rather than statistical analysis. (Bell, 1993) The selection of qualitative methodology dictates the character of data gathering approaches done in relationship marketing context which is largely inductive (Creswell, 1994; Cuba and Lincoln, 1994; Quinn-Patton, 1987). The inductive logic means research should evolve in an undefined pattern rather than a determined specific result oriented pattern. Research therefore emerges from the field research with the interactions between the participants and the interviewees, as well as through the observations. In essence, this means while researching on relationship marketing services the framework in the beginning will be limited and predetermined on few objectives, after that the research will be let to evolve itself. In most of the cases it is hard to dissociate all deductive aspects but the plan is to keep this to a minimum. It is for this reason that the use of qualitative rather than quantitative research methods shall be employed. With the decision to use qualitative method decided, it becomes necessary to consider the specific applications that shall be used. Basically, it is necessary to consider the resources available to the research process. Many of the constraints placed upon qualitative methods involved issues regarding the amount of time available to the process. According to Bell The extent of your data collecting will be influenced by the amount of time you have. this may seem a rather negative approach, but there is no point in producing a grandiose scheme that requires a year and a team of researchers if you are your own, have no funds and in any case have to hand in the project report in three months . (Bell, 1993) This position makes several valid points, reminding us that one must ensure that the resources that are available to the research process are utilised fully. A qualitative, rather than quantitative approach is chosen because it is considered that many of the key factors in relationship marketing are socially constructed. (Hirschman, 1986). Phenomenological method has been used to provide informative and interesting interpretations of behaviour by a growing number of consumer researchers. However, at the onset it is important to note that phenomenology is not just a set of techniques for gathering, analysing and interpreting data; it is as much a philosophy whose intellectual foundations need to be understood if the method is to be implemented in its true form (Christina Goulding, 1999). It is decided to take a phenomenological approach, rather than positivist one, the reason to choose phenomenological, it was considered the subject matter of the study was unlikely to be objectively determined, this being the criteria for the positivist approach (Easter by-Smith et al, 1999), and the approach was suited to the socially constructed phenomen a that is the chosen area of research. A qualitative is used to aim to draw first hand experiences, in-depth motivations and personal feelings of interviewees towards relationship marketing and its role in telecom industry. One fundamental importance to this study is the fact that qualitative research will disclose problems, answers and insights that may go unnoticed in a quantitative study using closed or list questions. This may have limited the usefulness of the study and would probably not do justice to the fascinating and dynamic nature of marketing strategy. 3.4.1 Benefits of chosen approach: The benefit of qualitative research starts firstly with the fact it is not very time consuming. As Gilmore and Carson (1996) advocates qualitative techniques are highly appropriate for marketing research in the services industry, given the dynamic nature of the service delivery and they mostly occur through human interaction. They felt that the examination of complex and dynamic service situations could be more effectively achieved since the qualitative research process offers an open, flexible and experiential approach. It provides with the subjective information which may help to analyze the complex questions that cannot be answered. Respondents are encouraged to answer in their own words providing rich, fertile, but disorganized data Jankowicz (1993). It also provides the opportunity and opens the doors for the new research areas because of richer source of ideas. The qualitative research literature ( Kirk and Miller, 1986; Cresswell, 1994; Carson et al., 2001) proposes that quali tative research in common is reliable, valid and trustworthy, the authors were mostly watchful of the reliability, validity and general matters that are connected with drawing conclusions and making implications from non-probabilistic, small samples (Patton, 1990; Bock and Sargeant, 2002). Because of time restraints and availability of resources, the qualitative approach was the best option for the researcher conducting a single study. The value of qualitative approaches has become more apparent in consumer research over the past ten years with a number of researchers gaining insight into the phenomena not easily understood through quantitative measures (Woodruff and Schumann, 1993; Masberg and Silverman, 1996). 3.5 Data Collection Methodology Basically the data was collected in two stages, shown below. First Stage: Theory Study The first part of the research was completed by examining and reviewing previous literature, which facilitated to develop the themes which were discussed in more depth by the later stage of the research study. Second Stage: Focus Groups exploration In the second stage the researcher is trying to demonstrate the need for the appropriate approach from all the available methods in qualitative research methods because of the exploratory nature of the study. Convenient sampling method was used fort he chosen method: focus groups. Convenience sampling is the method used for selecting the sample for the chosen research methods: focus groups and semi-structured interviews. Although these methods of non-probability sampling are less scientific than the more robust methods of probability sampling (Zikmund, 2000), it is appropriate for the purpose of this study as it is best utilized for exploratory research (Zikmund, 2000). The groups enabled the researcher to explore themes, and expressed feelings much better than the questionnaire, which would not have enabled the expansion of topics in the same way. According to (Morgan and Krueger, 1998) The goal in focus groups is to gain an understanding by hearing from people in depth and this requires selecting a purposive sample that will generate the most productive discussion in the focus groups. A purposive sampling strategy chooses the focus group participants according to the projects goals. Focus groups are a qualitative technique allowing for the explicit use of group interaction to produce data and insights that would be less accessible without the interaction found in a group (Morgan, 1990). Focus groups are an admirable technique at establishing the why behind the informant perspectives (Morgan, 1990). Focus group is an addition to an individual interview as focus groups are thought to produce more critical explanation than personal interviews (Watts and Ebbutt, 1987). The focus allows the interaction between the people of different races and careers to express them their feeling and share their thoughts or experiences. Different people are gathered and brought into conversation for a focuses discussion related to a specific subject or question the results are used to increase understanding of that particular topic. In market research focus groups have been exercised to learn about consumers approaches and feelings as well as developing marketing strategies (Crabtre e and Miller, 1992; Hedges, 1985; Keown, 1983). This method is open-ended. That is, they use a form of questioning in which the respondents are encouraged to answer in their own words while the researcher may have an idea about the kind of answers that should be expected, it is not possible to specify assumptions in advance. In focus groups the moderator asks a question to each member in turn. Inside these restrictions, though, the meaning has reasonably broader limitations and several ways of collecting data are viable (Mitchell and Branigan, 2000). The focus group is relatively unstructured and unrestricted; they provide bulky amounts of productive but disorganized data. Some new forms of focus groups are also emerging these days as online focus groups they have facilitated qualitative research to be the beneficiary for the electronic development. Conducting online qualitative research is getting more famous and significant as a method of gathering information and data to know the methodologies and its key benefits (Sweet, 2001). Focus are not always easy to plan and execute as Atiken (1996) argues the benefits of focus groups, but also point out that they are not easy to arrange, run and report on. Focus groups are also helpful if the respondents are friendly towards the researcher as qualitative interviews this also depends on the association between interviewer and interviewees in raising an open dialogue which can allow a joint construction of understanding in the interview (Kvale, 1996). Overall the chosen methodology which has suited the study better than that of a more quantitative nature, as the properties involved are not physical or easily measurable In the paradigm of qualitative research focus groups have many advantages and disadvantages that can be taken into consideration while exploring the research better synopsis could not be found on the limitations and strengths of the focus group method as qualitative consumer research than one written by Morgan and Spanish (1984, p. 260): In essence, the strengths of focus groups come from a compromise between the strengths found in other qualitative methods. Like participant observation, they allow access to a process that qualitative researchers are often centrally interested in: interaction. Like in-depth interviewing, they allow access to the content that readers are often interested in: the attitudes and experiences of our respondents. As a compromise, focus groups are neither as strong as participant observation on the naturalistic observation of interaction, nor as strong as interviewing on the direct probing of informant knowledge, but they do a better job of combining these two goals than either of the other two techniques. The researcher believes this is a useful combination and one which, for some types of research questions, may represent the best of both worlds. The focus group enables the researcher to explore themes, and expresses feeling much better than questionnaire. As Lovelock (1996) posits, focus group have been used very effectively to illicit useful information about likes, dislikes, wants and desires of the participants. Focus groups have these disadvantages which comprises of standing, information and cultural differences among respondents, group domination by intellectual persons, forceful agreement and are deficient in inconsistency in viewpoints (McDonald, 1993; Ulmenstein, 1995). The outcomes of the focus groups are unstructured. This deficiency of structure possibly will leave participants lacking a sense of completion and may provide respondent disappointment (Van de Ven and Delbecq, 1974). 3.6 Focus Group interviews The qualitative part of this study was designed to include both focus-group and semi structured interviews. It included two different kinds of tools for interviewing and collecting the qualitative data in order to achieve appropriate richness in terms of understanding the variables behind the relationship marketing and customers evaluations in the telecom sector. The researcher himself acted as a moderator because he knows that moderator can have a deep impact on the usefulness of focus groups, in view of the fact that he can control equally the content of what is said by respondents, (Myers, 1998) and manage of participation (Morgan, 1996). The researcher before deciding the participants of focus group always kept the goals in his mind about the different styles, status and experience participant remain involve. The first part of qualitative study involved two focus groups moderated by a research professional. Two sessions were conducted, including a two hour discussion per group. The two focus groups consisted of three people each. Some of them were students; users and the rest of them were from different call centres. This criterion was set partly because researcher want to compare the results under investigation to other groups. Prior to interviews, formal introductory letters stating the research objectives were sent to interviewees in o rder to remind and trust along with establishing relationship. These will be followed up by telephone calls and re-inforcement of research objectives which will enable interviewees to address any queries they have prior to the interviews. Semi-structured interviews of approximately forty minutes to one hour are used from the people who are working in call centres for managing customer relations and providing customer service. Focus group are also a consideration for this research, because interaction among respondents might have stimulated new ideas and thoughts that may not have arisen during one to one interviews, group pressures are immediate, the greatest potential for distorting the focus group research is during the group interview itself (McDaniel and Gates,1996) For example, focus group may be subject to unstructured discussions which drift far from research objectives. Furthermore focus group may also contain introverted and non-respondents. But for the research of relationship marketing in telecom industry focus group is a good option. From the 1970s, focus group used mainly in the sphere of market research (Morgan, 1997). They are now widely used in anthropology, communication, education, marketing, political science, psychology, nursing and public health. It is not easy to define an interview questions because of the variety of the types of interview. According to Patton (1980), it is a useful starting point: the purpose of interviewing is to find out what is in and on someone elses mind. Researcher interview people to find out from them those things we cannot directly observe. A variety of open-ended questions are considered for inclusion in focus group discussion and in interviews. A key consideration during the discussion is the accuracy of the information collected. Interviews and group discussion will not be capable of being repeated due to time constraints and professionalism. Throughout the session, questioning was purposeful to acquire the reason what participants feel about relationship marketing in current business. The best the researcher could do was to encourage the respondent to express their thoughts and experiences. Researcher tried let the discussion remain focused as he has to play the key role throughout. Analysis of the outcome of the groups was undertaken by collating the comments made and categorizing responses. According to Marshall and Rossman (1989), the advantages of interviewing that face-to-face meeting with informants obtains large amount of expansive and contextual data which facilitate access for immediate follow-up. Data collection for clarification and omissions is possible. Data are collected in natural setting because data obtains on non-verbal behaviour and communication. Interview facilitates analysis, validity checks, and triangulation, which also provides background context for more focus on activities, behaviours, and events. Interviewing is great utility for uncovering the subjective side, the natives perspective of organisational processes. Some of the disadvantages of interviewing that data are open to misinterpretation due to cultural differences, especially in diverse society. Depends on the co-operation of a small group of key informants and procedure are not always explicit. Interviewing depends on researchers opportunity or characteristics because data are often sub ject to observer effects; obtrusive or reactive because its dependent on the honesty of those providing the data , dependent on the ability of the researcher to be resourceful, systematic and honest; to control bias. 3.7 Analysis: Unquestionably, data analysis is the most composite and puzzling of all of the phases of a qualitative project (Thorne, 2000).Therefore, to analyze the data, it was important to choose a relevant method which suited the research approach. Considering all possibilities available Grounded Theory was decided to be the most suitable form of analysis, as grounded theory offers a way of attending in detail the qualitative material in order to develop systematically theories about the phenomena which have been observed (Turner, 1983). It also gives internal validity to a study because of its systematic processes. The discussion from each focus group was listened to a couple of times, and the transcription read a couple of times so as to develop a familiarity to the researcher with the content, as Hague and Jackson (1999) points out that with interviews it is generally good practice to transcribe them into typed up context and carry out analysis with this material. A lot of revelations became and most noticeable being the differences and similarities between the groups. The researcher spent time on examining upon the different parts of the discussions so as to attain a right understanding of what was actually meant by the respondents. Interpreting the data and simplifying meaning from the analysis (Miles and Huberman, 1994) is difficult task. All the emerging ideas were examined further at each stage of analysis, with the regular refining which formed the recoding stage of the grounded theory process. All through this analysis stage an attempt was made to relate the concepts to the previous re search where possible. Accessibility is essential to people within the organizations i.e. telecom industry that are involved in customer relationship management, management of customer data to retain the data of existing customers. Such sources would give key insights into how organizations are responding to the threats and opportunities of relationship marketing in the electronic age and with a freshness and energy that would deliver inspirational and perhaps leading edge thinking into e-marketing and the link with content. In summary the methodology of this research is developed from the question, to get better understanding of the concept relationship marketing. How content is being used to build relationship with existing customers. Throughout the development of the methodology, the most suitable research design methods is chosen with regards to this question alongside other more practical considerations. The limitations of research methodology are included accessibility to the research population of interest and time constraint. A major consideration in this study was perceptual and subjective bias although this is likely to apply to any research of this type and topic. However, ultimately the interpretation of the results is subject to the researchers own perception especially due to the researchers natural interest in the subject matter. 3.8 Methodological Critique This section reveals the flaws and defects which may have resulted because of the chosen methodology. Firstly, the qualitative approach was chosen but some practitioners who still believe that the qualitative research even now experiences from an uncertain image (Coldwell, 1990). The qualitative research which does not meet the requirements of validity and reliability as opponents of qualitative research time and again refer to the fact that this kind of research does not meet the demands of validity and reliability, standard which are usually viewed as the basis of any research. Indeed, as a consequence of the relative choice and lack of structure and inflexibility characteristic of most qualitative research methods it is simple to question validity and reliability in their conventional sense (Kirk and Miller, 1986; Warren, 1991; Warren and Cragg, 1991). Even the selected sample size was too small and cannot be said to provide the accuracy for the research as the small, qualitative study cannot maintain the power; mainly the sample studied cannot stand for the whole population sight and feelings. Methodological triangulation can be utilized to improve the reliability and validity of the facts (Denzin, 1989). Triangulation, whereby methods are derived from se veral sources, ideally using both qualitative and quantitative data would have been a superior approach this enhances validity (Threlfall, 1999). It would have also allowed cross referencing of data. As the researcher himself was the moderator, so it cannot be said a perfect condition for the focus group because a moderator for the focus group facilitation should be experienced and have some topic background, if available, would be an ideal moderator (Seggern and Young, 2003). The methodology of using focus groups and the availability of past research allowed the researcher to have data from different sources. The participants were known to the researcher and the majority were friends and colleagues, so the biasness to the discussion could have been created by them and the direction given by the moderator at times did not allow the respondents to express their true view, as the data acquired from the focus group is likely to symbolize the preconceived thoughts of the moderator as the approach of the subject interviewed (Threlfall, 1999). The group discussion in the focus group may let the respondents to leave the major conflicting views as it has been argued that group interaction can also be a major disadvantage of focus groups as it may inhibit the exchange of opinions and ideas and lead to the loss of minority or opposing points of view (Gordon and Langmaid, 1988). The discussion for this kind of study have provided the researcher with the substantial amount of data, some of which were relevant to the study and much which had no direct connection with the topic investigated because participants focus on one another rather than the researcher (Kitzinger, 1994). During the focus group discussion, respondents engaged in active talks to reach a same view for the group and it was hard to correctly record this conversation with a tape recorder, since on many occasions more than one respondent was conversing at one time. There is a possibility that the topic remain less or more inert throughout the discussion because the guide given by the questioner which may escort them the other way (Threlfall, 1999). In other terms researcher can say that the information gathered

Euthanasia Essay -- Euthanasia Essays

Euthanasia and Physician-Assisted Suicide   Ã‚  Ã‚  Ã‚  Ã‚   Individual cases presented to justify legalizing physician assisted suicide fail to deal with underlying medical failures to control pain, creating an illusion of control over death, and not acknowledging the thousands of patients murdered inappropriately. This is an interesting and a very controversial issue in today’s society. Euthanasia has negative sides, it can hurt society, and everyone needs to learn more bout it.   Ã‚  Ã‚  Ã‚  Ã‚  The word Euthanasia is Greek in origin. It arrived from the prefix â€Å"eu†, meaning fear, easy, and fortunate and from the word â€Å"thanatos† meaning death. The main idea of Euthanasia is that someone has a conscientious death or a fortunate one. In other words, we attempt to ease one’s pain by murdering another human being to give him/her a so-called â€Å"easy death† which is illegal and morally wrong. The key element of one human being taking the life of another human being is not present. It is exactly this element that causes euthanasia to be morally wrong (Gay-Williams,288)   Ã‚  Ã‚  Ã‚  Ã‚  There are different cases that might be hard to distinguish whether it is, or isn’t Euthanasia. There are murders in â€Å"just†, war, when trying to protect oneself, and in federal executions. It can be said that one of those is amiss; it would be arduous to prove that they are always amiss. When someone looks at those examples above and euthanasia, he/she can tell their inequality. The person who is murdered above is considered by the murderer as an adversary, an assaulter, or criminally culpable. But the individual in Euthanasia is neither of the three we mentioned (Gay-Williams, 288). As I defined earlier, euthanasia is taking someone’s life, either his/her own or of another person to add to that, the human being whose life is confiscated must be a person that is assumed to be experiencing a disease or injury from which regaining life cannot reasonably be anticipated. Ultimately, the attempt must be deliberate and intentional. Thus, euthan asia is purposely confiscating the life of a believed hopeless person, whether it is the person’s own or of a relative or friend, it is still euthanasia. It is critical to be apparent about the deliberate and intentional appearance of the death. If a desperate person is injected with the incorrect drug unintenti... ...Cited Darr, Kurt. â€Å"Physician-Assisted Suicide and the Supreme Court: Implications for Health Services   Ã‚  Ã‚  Ã‚  Ã‚  Delivery.† 22 Jun. 1997.

Biodegradable Plastics Contribution To Global Methane Production Environmental Sciences Essay

Industry of biodegradable Plastics is a freshly emerged sector, which originated to plan degradable plastics by common biological beings such as, bacteriums, algae and Fungi. Invention of bioplastics specifically resulted to suppress the monopoly of petrochemical plastics in the market since ; petrochemical plastics have become a onerous issue due to economic emphasis, environmental impacts and resource deficit caused by use of non-renewable crude oil oil. Since biodegradable plastics are designed to degrade in the biological environments, the most common and executable method of terminal of life scenario is landfills. Objective of the present survey is to gauge maximal extra methane coevals via biodegradable plastics under landfill anaerobiotic conditions. Literature was reviewed on presently available types of biodegradable plastics, single polymers comprised, production capacity ( twelvemonth 2007 ) and methane production informations from single polymers. Empirical information fo r methane coevals were based on the published experimental literature on single polymers under research lab simulated landfill conditions utilizing thermophilic anaerobiotic sludge digestion. Methane coevals in organic molecules was theoretically calculated based on derived presently available chemical equations, presuming standard temperature and force per unit area conditions. Global methane part by biodegradable plastics was calculated merely utilizing theoretical values since no sufficient informations were available at experimental conditions. Study demonstrates 0.011 % of planetary part of methane by biodegradable plastics if full production capacity in twelvemonth 2007 is assumed to be landfilled and wholly biodegraded. 1.52 % of methane is contributed to planetary emanations, if 90 % of petrochemical plastics are substituted by biodegradable plastics, which the per centum of petrochemical plastics could be technically substituted harmonizing to the studies of PROBIP ( 2009 ) . In comparing of theoretical and experimental informations, experimental information was in the scope of 55.9- 68.84 % upon theoretical informations. The estimated values demonstrate a low degree of methane emanation compared with other anthropogenetic methane beginnings, showing a negligible impact to planetary methane emanation and/or planetary heating by biodegradable plastics. Introduction Plastics are man-made, typically long concatenation polymeric molecules. Substitution of natural stuffs by plastics came about to the scenario back in 1907 after innovation of man-made polymer â€Å" Bakelite † from phenol and methanal ( Thompson et al. , 2009 ) . Improvement of the synthesis methods and techniques have ameliorated the quality of plastics with more stable and lasting belongingss ( Shah et al. , 2008 ) . Today plastics have become an indispensable portion of the worlds ‘ life peculiarly due to their extended usage in packaging, cosmetics, chemicals, and detergents. Plastics we use today are synthesized stuffs extracted from rough oil, coal and natural gas ( Seymour, 1989 ) which is termed as Petroleum based plastics. Property of high doggedness ( really slow biodegradation rate ) of plastics have created being immune to environmental degradability which mounted social consciousness and concerns of proper disposal and direction ( Albertsson et al. , 1987 ) . Wide assortment of plastics are manufactured including polypropene, polystyrene, polyvinyl chloride, polythene, polyurethane and rayonss with estimated planetary production of about 140million dozenss per twelvemonth ( Shimao 2001 ) . Therefore inordinate utilizations of plastics have exerted a immense force per unit area globally in footings of salvaging of confined petroleum oil, waste disposal and direction, and environmental diversion. To get the better of the jobs related to petroleum based plastics attending of scientists have devoted their attending that lead to advance research activities to give rise to alternate stuffs, intended to degrade through biological procedures ( Shah et al. , 2008, Lenz and Marchessault, 2004, Amass et al. , 2001 ) . A new type of thermoplastic polyester was foremost produced by Imperial Chemical Industries Ltd- London in 1982, which was considered to be wholly biodegradable ( Anderson and Dawes, 1990 ) . The invented merchandise is known as biodegradable plastic since, it ‘s degraded by environmentally available micro-organisms. Term Bioplastic ( BP ) is perplexingly used today to construe bio-based and bio-degradable stuffs. However the survey will chiefly see on the Biodegradable plastics ( BDP ) , which is intended to utilize as a promising solution for the crude oil based plastics. Harmonizing to ASTM definition of BP, BP is a degradable plastic in which the debasement con sequences from the action of naturally-occurring micro-organisms such as bacteriums, Fungis, and algae ( Narayan, 1999 ) . Many different types of BPs have been successfully produced and have invaded the market during past few old ages. BPs are synthesized utilizing works extracted polymers or usage of growing of micro-organisms. Tailoring the belongingss of works extracted polymers via chemical alteration of the chief polymer by hydrolysable or oxidisable groups and utilizing polymer blends ( Amass et al. , 1998 ) have amended BP to utilize in a wide scope of applications contained with novel and good features. The primary end expected over innovation of BPs was the environmental concerns including waste direction, decrease of nursery gas release, and salvaging of non-renewable energy ( petroleum oil and gas ) . Apart from that secondarily, economic facets and new proficient chances came into scenario ( PROBIP, 2009 ) . Today BPs are popular compounds used in packaging stuffs, wetting agents, as biomedical stuffs ( eg: lesion dressings, drug bringing, Surgical implants ) , and agricultural compounds ( eg: command the fertiliser and pesticide release ) . BPs used as packaging stuffs has led to first-class direction scheme chiefly to forestall environmental accretion ( Amass et al. , 1998 ) . Merely 0.3 % ( 0.36 million metric dozenss ) of the world-wide production of conventional plastics has replaced by biodegradable plastics by the twelvemonth of 2007. In twelvemonth 2007 universe plastic coevals was reported as 205 million dozenss ( Gervet and Nordell. , 2007 ) . However 90 % of the conventional plastics are estimated the per centum is capable of technically substituted by BPs. There is an rush in coevals of bio based plastics globally that resulted in an estimated planetary growing of 38 % from 2003 to 2007 ( PROBIP, 2009 ) . Initially when BPs were come ining to the market ( 1990 ) no standard processs were existed to look into the biodegradability of the plastics. To forestall misconceptions with biodegradability of BPs, criterions have been developed by standard organisations to place the actual biodrgradability of BPs in trade good ( Mohee et al. , 2007 ) . At the terminal of the service life BPs wind up in landfills, anaerobiotic intervention workss or composting installations. Based on the degradable belongingss and the belongingss of the material terminal of life, the options vary. Landfill disposed BPs will finally undergo anaerobiotic biodegradation where, the stuffs are disintegrated to methane, C dioxide, H sulfide, ammonium hydroxide, H and H2O as a consequence of series of microbic metabolic interactions ( ATSDR, 2010 ) . Methane gas is a well-known and of import by merchandise which public attending has paid as a planetary heating gas and besides as an economically feasible biofuel. The surv ey is a preliminary effort to look into the degrees of extra methane gas released if terminal of life option is chosen to be a landfill utilizing normally available types of BPs globally, with different biodegradability degrees.Back landTypes of BPs Literature studies legion types of BPs in the market today, such as amylum plastics, Poly glycolic acid ( PGA ) , Poly lactic acid ( PLS ) , poly lactic acid-co-glycolic acid, poly 3- hydroxybutanoate ( P3HB ) , Poly 3- hydroxyl valerate ( PHV ) , Polyethylene succinate ( PES ) , Poly butylenes succinate, Poly propiolactone ( PPL ) , starch blends, etc ( Figure 1 ) ( Shah et al. , 2008, PROBIP, 2009 ) , derived from renewable resources such as amylum, works based oils, or cellulose ( Beta analytic, 2010 ) . The survey covers 5 major groups of BDPs presently available in the market with inside informations on different makers engaged in fabricating procedure ( Table 1 ) . Except these chief groups mentioned, chitin ( polyose ) , protein ( collagen, casein ) , and amino acid based BDPs are manufactured in undistinguished degrees, which are non covered in this survey. Main group of polymer contributes the planetary BP production is Cellulose plastics, which the production capacity is ab out 4000Mt per annum. To be considered as a bioplastic, it should be certified lawfully through criterions, EN 13432 or EN 14995 in Europe, ASTM D-6400, ASTM D6868, ASTM D6954, ASTM D7081 in United States, DIN V4900 in Germany or ISO 17088 in other states ( Beta analytic, 2010, ASTM, 2010 ) . As mentioned earlier all BPs are non biodegradable and the biodegradability is based basically on the molecular construction of the compound. ASTM D-6400 requires 60-90 % decomposition of BPs within 180 yearss in natural environment in order to be considered as a biodegradable plastic. ASTM has demonstrated both aerophilic and anaerobiotic criterion methods to place ( severally in composting environments and anaerobiotic digestion procedures ) the extent of biodegradability of BDPs ( Narayan, 1999 ) . Decomposition Degradation and possible degradability of a peculiar BDP varies depending on the environment exists: anaerobic or aerobic ( Ishigaki et al. , 2004 ) . Based on the debasement belongings of a peculiar BDP, terminal of life option should be chosen, whether it is to be disposed in a landfill or composting installation. Different types of dirt micro-organisms ( bacteriums and Fungis ) are responsible for the biodegradation of different types of BPs specifically ( Shah et al. , 2008 ) . Rate and procedure of biodegradation of BPs rely on the Soil belongingss, nature of the pretreatment, features of the polymer such as tactual sensation, mobility, molecular weight, functional groups present, additives, handiness and optimum growing of specific micro-organisms ( Artham and Doble, 2008, Glass and Swift, 1989, Gu et al. , 2000 ) . Initially biodegradation starts with decomposition of the polymer via physical and biological forces. Some fungous hyphae are able to perforate the polymer construc tion and cause clefts and swelling of the stuff ( Griffin, 1980 ) . Heating, chilling, stop deading melt, wetting and drying like physical forces besides contribute the mechanical debasement procedure ( Kamal and Huang, 1992 ) . By and large high molecular weighted polymers have a lesser possible to biodegrade than the low molecular weighted compounds. Broadly extracellular and intracellular microbic enzymes are responsible for biodegradation procedure, and so converted into oligomers, dimers and monomers which can be easy penetrable into bacterial cells. Therefore utilizes for bacterial energy production let go ofing CO2, CH4, and H2O ( Hamilton et al. , 1995, Gu et al. , 200 ) . Present survey will be given accent landfills, as the terminal of life clip option. Less information is available on the biodegradation of BDP in landfill anaerobiotic conditions than aerophilic composting. Thence more probes have to be implemented and few have been reported ( Yagi et al. , 2009 ) . In a l andfill high per centum is readily degraded by anaerobiotic communities in anoxic conditions. As a consequence of series of physical, chemical, cubic decimeter and biological reactions that take topographic point in a landfill, landfill gas is produced, with changing composings based on the type of waste contained ( Barlaz et al. , 1990 ) . Anaerobic debasement of C, Hydrogen and Oxygen incorporating substance is given by the Buswell equation as follows ( Yagi et al. , 2009 ) . CnHaOb + ( n- a/4 – b/2 ) H2O ( n/2 + a/8 – b/4 ) CH4 + ( n/2 – a/8 + b/4 ) CO2 ( A ) Anaerobic decomposition of Carbon, Hydrogen, Oxygen and Nitrogen incorporating substance is given as follows ( Behera et al. , 2010 ) . CaHbOcNd + ( ( 4a-b-2c+3d ) /4 ) H2O ( ( 4a+b-2c-3d ) /8 ) CH4 + ( ( 4a-b+2c+3d ) /8 ) CO2 + vitamin D NH3 ( B ) CO2 and CH4 are the chief gaseous substances released during anaerobiotic debasement of any compound. Methane produced in landfills is recovered as an energy beginning where provides an economic advantage. However if non recovered, methane would readily come in to the ambiance, which is listed as one of the major subscriber to planetary heating. Methane is an effectual heat pin downing agent in the ambiance and over 20 times more powerful than CO2 ( USEPA, 2010 a ) . Surveies have reported on methane outputs obtained via anaerobiotic biodegradation for few polymers ( Cellulose ester, Polycaprolactone and Poly lactic acid ) and most are yet to be studied.Methane as a potent planetary heating gasGlobal heating is understood as the chief causing of planetary clime alteration. Global heating is caused due to increase of green house gases in the ambiance such as Carbon dioxide, methane, Nitrous oxide, and H2O vapour ( US composting council, 2009 ) . Methane is considered as a green house gas with high heat pin downing capacity which lasts about 9- 15 old ages in the ambiance. Global warming possible ( GWP ) of green house gases are represented in relation to a mention gas, CO2, where GWP is considered as 1. Global warming potency of methane gas is 21 which infers, 21 times more effectual heat pin downing agent than CO2. Methane is emitted to the ambiance chiefly from anthropogenetic and natural beginnings. 50 % of methane in the ambiance is attributed to anthropogenetic beginnings such as fossil fuel burning, biomass combustion, rice cultivation, carnal farming, and waste direction. Contribution of anthropogenetic methane to planetary green house gas emanation was 282.6 million dozenss in the twelvemonth 2000 ( 22.9 % ) as declared by USEPA ( 2006 ) . Natural beginnings of methane emanations include emanations from wetlands, permafrost, white ants, oceans wild fires and fresh H2O organic structures. Degrees of methane emitted from each part or state depends on facto rs, such as climatic conditions, industrial and agricultural lands, energy type used and godforsaken direction processs. Largest methane emanation homo related beginnings in USA are landfills, carnal farming, and manure direction where the 2nd highest of the list goes to landfills. In the facet of planetary methane production, landfills attributed the 3rd highest beginning of emanation and globally methane part by landfills was over 12 % for twelvemonth 2000 ( USEPA, 2010 B ) . Organic compounds in a landfill, upon decomposition release methane as mentioned above and recent appraisal suggests that 72 % of MSW watercourse contained with organic substances: paper, nutrient garbages, yard dust, textiles/ leather, and wood. Percentages of each MSW constituent landfilled was severally, 34 % , 12 % , 13 % , 7 % , and 6 % ( US composting council. , 2009 ) . Thus methane coevals from each MSW constituent may be assumed being in the same order as above from each MSW constituent, since methan e production is relative to the C sum in an organic substance. Thus paper is the chief methane gas subscriber to the ambiance from a landfill while others play a minor function. BDPs is fresh emerging organic compound set in the landfills and besides a new planetary beginning of methane breathing from a landfill.Gas Generation theoretical accountLandfill gas appraisal is utile for landfill operators, regulators, energy users and energy recovery undertaking proprietors to look into how gas is produced and recovered in a peculiar clip period. USEPA has generated a Landfill methane gas appraisal theoretical account to imitate the gas production in landfills utilizing first order decay curve, which is written as, M ( T ) = M0 vitamin E -kt. Where M ( T ) is the mass of a batch waste staying at any clip, M0 is the initial mass of waste, K is the decay rate ( clip -1 ) and T is the clip since decay was begun. Gas production is straight correlated to mass doomed, which is termed as L0 ( M3 of methane per metric ton of waste ) . Entire Volume of gas ( G0 ) that can be produced by the debasement of mass of weight ( M0 ) is, calculated utilizing the equation, G0 = L0 M0. BDP is a freshly emerging landfill constituent which contributes the planetary methane coevals. The survey will supply an appraisal of extra methane produced upon this new reaching.MethodsStudy was based on appraisal of extra methane gas sum produced from landfills with subsequent outgrowth of BDPs to the market. Literature was reviewed related to trade name names, measure, polymer types incorporated and biodegradability ( particularly in footings of methane production ) of BDPs normally found in the planetary market ( Table1 and Table 2 ) . Manufacturer and measure informations obtained were associated with the twelvemonth 2007. This survey has considered merely biobased and non biobased BDPs and not degradable bio based or non biobased plastics have non been used for analysis as they are incapable of degrade in a landfill and release methane. Study was carried out in 4 stairss. Measure 1: Methane production per twenty-four hours was calculated utilizing published experimental informations on methane gas production in fake landfill conditions presuming entire manufactured BDPs were being landfilled ( Table 2 ) . Biodegradability of a peculiar BDP is likely to change based on the per centums of single polymers contained in the blend. Although production capacity was available in regard to a peculiar trade name name, no production informations was available for single polymers individually. Since a peculiar manufacturer industries different types of BDP stuffs related to fabric, agribusiness, biomedical points and packaging, per centums of single polymers used for blends vary mostly from each other even within the same trade name name. Therefore it ‘s hard to nail a distinguishable per centum for each polymer in a peculiar BDP being manufactured. Further information on per centums of each polymer are neither readily available from the makers ‘ web sites nor descriptive surveies have done sing per centums. Therefore trade name names with multiple polymer types were assumed to be every bit distributed, therefore manufactured capacity from each polymer was obtained by averaging the manufactured capacity of the peculiar trade name name. Most published literature was based on the biodegradability of single polymer types instead than the biodegradability of a peculiar trade name name except for Mater Bi amylum BDP ( Mohee et al. , 2007 ) . Measure 2: Methane production per twenty-four hours was calculated utilizing theoretical stoichiometric methane production informations presuming entire biodegradation of the compound and entire manufactured BDPs ( 2007 ) were being landfilled. Trade names with multiple Numberss of polymers, per centums of single polymers are assumed every bit distributed as mentioned in step1 ( Table 3 ) . Methane gas sum released is theoretically calculated utilizing the chemical equations ( A ) and ( B ) . Maximum biogas ( CO2, CH4 and NH3 ) sum produced by debasement of 1 kgs ton of Poly lactic acid ( ( C2H4O2 ) N ) was calculated to be 7.5 ten 10 5 M3 ( ( 106/60 ) x 22.4x 2 ) at standard temperature and force per unit area. CH4: CO2 ratio for poly lactic acid is 1:1. Theoretical maximal volume of CH4 produced calculated harmonizing to the combined gas jurisprudence was reported to be 3.73 ten 10 5m3, presuming entire biodegradation of the compound. Table 3 displays the maximal theoretical methan e volume produced at standard temperature and force per unit area for C, H, O and N related polymers intended to discourse in this survey. Measure 3: Maximal methane production was calculated sing the sum of BDPs being landfilled per twelvemonth when 90 % ( the possible sum that can be technically substituted by BPs from petrochemical plastics in usage today ) of petrochemical plastics were substituted over BPs. All BDPs produced are assumed to be readily ( during a period of twelvemonth ) biodegradable in this scenario. Measure 4: Contribution of landfilled BDPs to planetary methane emanation was calculated utilizing the entire methane emanation informations obtained from measure 3 and step 4.RESULTS AND DISCUSSIONDatas on methane coevals ( Table 2, step 1 ) was obtained from published experiments on anaerobiotic decomposition of single polymer compounds, imitating landfill, thermophilic conditions by utilizing anaerobiotic sludge as the medium in controlled research lab conditions. However, since different writers have used different conditions with different types of sludges and diversed microbic communities, ( affects diverseness of microbic communities ) ( Abou-Zeid et al. , 2004 ) would impact the dependability of the survey in using the values for comparing, due to debut of many prejudices. It was non possible to gauge planetary methane production based on published experimental informations since sufficient informations were non available to cover a sensible figure of polymers attended this s urvey. However, appraisal for planetary methane production from BDPs was able to obtained by utilizing theoretical computation to near the aims as showed in measure 2, Table 3 ( see appendix for computations ) . If assumed the full manufactured BDPs in twelvemonth 2007 were landfilled and entire landfilled is wholly biodegraded, the methane sum produced was calculated to be 8.31 ten 10 8m3. Global part resulted was 0.011 % in this scenario ( see appendix ) . MSW watercourse is declared to be composed of 205 million dozenss of petrochemical plastics in twelvemonth 2003 ( Garnet and Nordell, 2007 ) . The sum of BDPs that could perchance replace to petrochemical plastics was calculated to be 184.5 million dozenss. Assuming equal proportions of different BDPs tabulated in Table 2 are being landfilled, the sum of methane released is calculated to be 1.06 ten 1011m3 / twelvemonth. 90 % permutation scenario is an appraisal undertaken to understand whether methane released causes important part to planetary anthropogenetic methane gas emanation, in its maximal degree of BDP industry. The scenario is responsible for 1.38 % of planetary methane part. This was 116 % of entire landfill methane coevals based on the twelvemonth 2006 sum methane emanation ( USEPA, 2006 ) , which is higher than the entire current landfill methane coevals. The values were obtained on the footing of 2007 BDP industry informations nevertheless expected entire plastic production will besides be raised seemingly at the clip of 90 % permutation petrochemical plastics upon BDPs. Entire BP production capacity amounted to be in twelvemonth 2020 is 1.5-4.4 million dozenss ( PROBIP 2009 ) . In comparing of the methane outputs ( m3/kt ) from theoretical stoichiometric computations and research lab measurings ( Table 4 ) , extremely vary. It is obvious that, experimental methane production in laboratory conditions is lower than the theoretical information. Percentage of experimental methane emanation was in the scope of 55.9-68.84 % of the theoretical values, when compared the methane emanation degrees of available experimental informations ( PCL and PCL ) . Methane sums will be farther diminished if methane emanation is calculated sing the experimental information. Efficiency of biodegradation procedure occur in a landfill governs the rate and sum of methane generated into the ambiance. Numerous factors such as size of waste atom, composing of waste, pH, temperature, design of the landfill, foods and as the most of import factor wet control the methane emanation in a landfil ( Micales and Skog, 1996, Augenstein and Pacey, 1991 ) . Rathje and Murphy ( 1992 ) have demonstr ated mummification of garbage under degrees where, a landfill does non have optimal degree of wet hindering debasement or methane release ( Barlaz et al. , 1987 ) . Bogner and Spokas ( 1993 ) have shown that C transition value of 25-40 % for even readily degradable stuffs in a landfill and Aragno ( 1988 ) reported 35-40 % organic affair debasement to Carbon dioxide and methane under ideal laboratory conditions. However in the present survey Methane coevals resulted was higher than the published literature, showing higher methane emanations from BDPs than other beginnings such as wood, paper, etc. Therefore under existent landfill conditions released methane sums is lesser than the controlled research lab obtained values as confirms by published informations and informations from the present survey. Further debasement procedure in a landfill takes topographic point over decennaries of periods and even after 20-30 old ages of period big measures of non-degraded parts have been observe d even for readily degradable stuffs ( Micales and Skog, 1996 ) . Therefore methane outputs per twelvemonth should be more lessen than the quoted values in the survey. Efficient and effectual usage of landfill methane as a good fuel or enrgt beginning would farther relieve the methane release into the ambiance in landfills ( Gregg, 2010 ) .SUMMARY AND CONCLUSIONSThe survey estimates maximal extra planetary theoretical methane resulted from decomposition of BDPs which is a fresh methane beginning emerged from landfills. Result suggest that the planetary part of BDPs to methane coevals is relatively less compared with other anthropogenetic beginnings. However in comparing of the methane emanation from BDPs, with other landfill constituents, BDPs are likely to lend a considerable sum of methane, which demonstrated the highest sum of methane emanation other landfill constituents. Experimental information groundss an overestimate of the theoretical estimations. Study has come across with many premises in each word picture scenario, which weakens the appraisal. However survey provides an appraisal of the extra methane gas released globally due to BDP landfilling, where no surveies or appraisals have done so far in a maximal possible logical and scientific manner using available informations. Further surveies on single polymer debasement are indispensable in order to beef up and verify the consequences obtained for sound actual appraisals.MentionsATSDR ( Agency for Toxic substances & A ; Disease Registry ) . 2010. hypertext transfer protocol: //www.atsdr.cdc.gov/hac/landfill/html/ch2.html.

pollution in the fox river essays

pollution in the fox river essays In Health Occupations Academy, students are offered numerous opportunities that outside students are not. One of them being the class Advanced Topics In Medical Science. In this class, students are exposed to debates and problems of the environment first semester, and health and medical issues second semester. Throughout first semester we engaged in multiple environmental issues, the biggest being water pollution. We started this unit by looking at frog deformities and the main cause of them. This led into the water pollution problem. We came across the issues of human pollution both chemically and physically. Mr. Lundquist introduced us to chemical testing first by going to the school's pond. Here we tested by only looking, not physically testing. We saw that the pond had an excessive amount of moss, meaning there were high phosphate levels in the water. This is caused by the lack of movement of the water and the fish's bowel movements, which produce phosphate. This experience ga ve us a taste of what the actual river walk was going to be like. During the time we were planning on doing our testing, there was a controversy between the Friends of the Fox and Fox Metro. The Friends of the Fox is a community formed group to protect the Fox River, and Fox Metro is Aurora's water treatment center. Friends of the Fox claim to have gotten much, much, higher levels of phosphate than Fox Metro had recorded. So we hoped that with our testing, we could find out ourselves which source had the right information We took a trip Students can make a difference! to where the Marina Valley Water Treatment Center effluent was found, then to the mouth of the Waubonsee Creek and the Fox River. Here we met Dr. David Horn and members of the Ecology Club from Aurora University. We split up into three different units. In one unit we did the actual testing on the Marina Valley effluent, then on the Waubonsee Creek water. In this unit we tested for ni...

Application Of GIS In Tourism Tourism Essays

Application Of GIS In Tourism Tourism Essays Application Of GIS In Tourism Tourism Essay Application Of GIS In Tourism Tourism Essay Introduction: Tourism is one of the most quickly increasing concern sectors in the universe and the success of this concern sector varies from state to state depending on different policies, ability to develop sufficient substructure to back up, ability to pull off and make market and overall selling through the whole universe about the merchandise. Many of the states depend on the touristry sector for their economic growing. To advance, program, implement, manage and selling, touristry are non easy undertaking at any degree of any state. There are batch of factors affect touristry in different ways. To keep all facets of touristry in a planned, sustained and economically sound manner, calculating and IT technologies installations are necessary in this modern universe. GIS- the particular analytical tool can be helpful in touristry sector at different ways. GIS is now recognized widely as a valuable tool for managing, analyzing, and exposing big volumes of diverse informations to many different de grees of planning activities. In instance of touristry planning and direction, GIS is utilizing as a really utile tool. Definitions: It is of import to understand Tourism and GIS clearly earlier discoursing the application of GIS in touristry. Different sections of touristry require different types of informations and analysis. In be aftering touristry, to develop touristry activities further, to discourse touristry chance, to analysis tourer Numberss, to market research GIS can be used otherwise. The definitions and some facets of GIS and touristry are stated below briefly- Gilbert: Geographic Information System ( GIS ) is considered as important scientific discipline and analytical tool in the whole universe for modern research and surveies specially related to spacial informations. Uses of GIS in the developed states cover a broad scope of countries whereas the development states are utilizing this utile tool in some limited sectors due to miss of skilled staffs, adequate support and some other proficient drawbacks. Geographic Information System ( GIS ) is an analytical tool, originated from Computer Aided design ( CAD ) helps to make maps at different graduated tables in different projections with a database to bring forth new information and nowadays it in different formats ( other than maps ) . It besides creates links between spacial and tabular informations and happen out spacial relationships between the characteristics of maps. It helps to roll up, shop and integrate spacial informations to analyze and show them as new information. It is considered as a powerful tool to execute these plants. GIS is non a field by itself but instead the common land between information processing and the many Fieldss using spacial analysis techniques ( Tomlinson, 1972 ) . GIS is computer-assisted systems for the gaining control, storage, retrieval, analysis, and show of spacial informations ( Clark, 1986 ) . GIS is a powerful set of tools for roll uping, hive awaying, recovering at will, transforming and exposing spacial informations from the existent universe ( Burrough, 1986 ) . Tourism: Tourism is the activities of people during his leisure period, apart from his life, usual environment for a fixed period of clip and executing some other activities. To advance, program and implement touristry activities, spacial informations are required as it depends on location, environment and some other factors. The term tourer is derived from the word tour intending a journey at which one returns to the get downing point ; a round trip for concern, pleasance or instruction during which assorted topographic points are visited and for which in path is normally planned. ( Murphy, 1985 ) . Tourism is a composite of activities, installations, services and industries that deliver a travel experience, that is, transit, adjustment, feeding and imbibing constitutions, amusement, diversion, historical and cultural experiences, finish attractive forces, shopping and other services available to travelers away from place. ( Tourism and Leisure Committee, 1997 ) The international national brotherhood of official travel administrations ( IUOTO ) in 1968 declared visitant as- any individual sing a state other than that in which he has his usual topographic point of abode, for any ground other than following an business remunerated from within the state visited. There is another term excursionists is used as visitants but there are difference between tourer and sightseers. Tourist- who are visitants doing at least one over dark halt in a state or part and remaining for at least 24 hours. Excursionists- who are visitants that do non do an over dark Michigans but pass through the state or part. An sightseer stays for less than 24 hours and includes day-trippers and people on sails. Harmonizing to Leiper, touristry is a system that consists three elements- the individual who makes circuit, geographical location or topographic points that travelled during circuit and the whole sector that controls the full system of touristry. The categorization is given below: Tourists- it means the individuals or homo who is doing circuits. That indicates the homo who is the chief histrion of the full system. Geographic elements- geographical location is classified three more categories traveler bring forthing region- bring forthing market for touristry, push to excite and actuate travel. Tourist hunt for information, engagements, departs. tourers destination region- crisp terminal of touristry. Pull factors of touristry. transit route region- non merely the topographic point of short period of stay to make concluding finish but besides intermediate topographic points which may be visited ( Cooper, et.al. , 2005 ) . In this subdivision push and pull factors have been stated where the push factors are those which influence people to go such as vacations from work, run intoing with relations, instruction and concern intents and some clip spiritual and medical intents. The pull factors are the attractive sites, museums, amusement Parkss, natural heritage sites and other attractive sites or festivals. Tourism sector- Tourism sector means the whole concern sector and the whole administration that supply different merchandises for clients to pull. Here the merchandises are tourist attractive forces and the clients are the tourers. In some instances, touristry is defined as the full activities of a tourer individual during his circuit. From a conceptual point of position touristry is -the activities of a individual going to and remaining in topographic points outside their usual environment for non more than one back-to-back twelvemonth for leisure, concern and other intents. ( WTO and UNSTAT, 1994 ) , ( Cooper, et.al. , 2005 ) . That means the touristry is a construct, means the activities of a going individual. From get downing point of the journey until it ends, touristry is at that place. When the individual is back to his usual life environment, touristry terminals for him. The whole activities ( sight visual perception, nutrient, adjustment, shopping etc. ) during the circuit are considered as touristry. There are some critical points to specify tourer and touristry as it depends on the clip continuance or the entire length of travel or circuit. If the entire travel clip or entire length of travel is more than a twelvemonth or less than a dark it will non be accepted as a touristry activity. Minimum length of stay- one dark ( visitants who do non remain overnight termed as same twenty-four hours visitants or sightseers ) ; Maximum length of stay- one twelvemonth. One more point is involved to specify touristry. That is distance. Distance from the usual life environment is considered. How far a traveler is traveling from his usual environment is a inquiry. World Tourism Organisation ( WTO ) suggests that if a individual is going at least 160km off from his life environment will be considered as touristry. Categorization of tourers: Depending on the standards of tourers, their finish, intent of travel, tourers are classified into different classs. The different classs of tourers have different picks, different finishs. So planning and implementing touristry for them and using different tools for analyzing touristry informations varies. Some categorizations of tourers are given below: Within range of travel and touristry: International- intercontinental, continental: individuals who are going from one state to another. They are known as International Tourist. Others: commuters, crews, pupils, migrators, and impermanent workers. Domestic- interregional, regional: individuals who are going within the state but from one part to another. From example- going from London to Scotland. Depending on the topographic points ( largely international ) : Inbound: tourers who are coming to a attractive finish are inward tourer for that peculiar topographic point. Example- a individual is going to London from any part or any state. That individual is inward tourer for London. Outbound: tourers who are traveling to another topographic point or go forthing a topographic point are outward tourers for the leaving topographic point. Example-a individual is going from London to any other part or state. He is outward tourer for London. Purposes: Depending on the intents of travel, tourers are classified as good. Some travel for concern, some for faith, some for festivals, some to run into their relations, some for instruction, some for jaunt etc. Depending on the intents of the tourers, their activities varies. Incentives of travel: In general there are some incentives for going. They are-War, faith, trade, find, festivals, wellness. Elementss need to pull tourer: Merely the intents can non act upon people to do a circuit. There are some elements which attract tourer for a peculiar location. The elements are- Transport, engineering, attractive forces, adjustment ( with nutrient ) , finish organizer. Transport- this is the most of import component to pull tourers. If there is deficiency of conveyance installations, people will be less interested for going to that specific location. There are three manners of transport- land, H2O, air. Land conveyance consists of route and rail. Sometimes transport installations themselves act as touristry specially in H2O and air conveyance. Technology- from the international point of position, engineering is really of import for touristry. Absence of engineering, deter international touristry as there are limited connectivity and opportunity of being isolated during touristry. In this instance, proper public-service corporation supply and specially telephone, Mobile and internet connexion are critical to pull international tourers. Attractions- it indicates chiefly natural and semisynthetic attractive forces. Aesthetic beauty of a topographic point, subject Parkss, memorials, sculptures, museums, sea beaches are of import. Some topographic points become attractive for touristry without holding aesthetic beauty or any amusements. Religious topographic points, historical topographic points, archeological sites are tourists attractive forces as good. Accommodation-if the adjustment and nutrient supply are non appropriate, touristry can non prolong as tourers are non attract. During travel or touristry, tourers need proper nutrient and remainder. Without these the whole touristry may travel in vena. On the other manus, some attractive hotels, some nutrients ( particular dishes-local or Continental ) are tourist attractive forces by themselves. Destination organiser- finish organizer indicates the factors those are related to a tourer finish apart from the top elements. It includes the entire system of a peculiar topographic point, security, attitude of local people and over all how the whole touristry is managed at that place. Factors impacting development of touristry: There are two types of factors that affect the development of touristry. Micro and macro. Macro factors: MACRO factors are the external factors of touristry. In short, they are known as PESTEL ( Political, Economical, Social, Technological, Environmental, Legal ) . Political- political factors indicates govt. attitude, political state of affairs of the state, political stableness the state etc. Economic- this indicates the economic status of the host state. Fiscal policy, economic growing etc. are included here. Social- over all societal status, societal construction, norms and societal values, societal civilization, behavioral form of the host state etc. are included in this sector. Technological- usage of engineering, development of engineering, handiness of modern engineerings ( cyberspace, nomadic web, Wi-Fi, etc. ) are the factors of touristry. Environmental- natural catastrophes, eco-tourism, degree of pollution, green environment, seasonal fluctuation etc. are the environmental factors of touristry. Legal- legal facets towards tourers, legislative bindings, revenue enhancement regulations, legal position towards tourists etc. Micro: Micro factors are the internal factors of touristry. Supplier, distributer, stakeholder, stockholder, consumers, employees, rivals, public etc. are the micro factors of touristry. Now a yearss, it is realized that Tourism is a manner of conserving the environment, making occupations and advancing more touristry. Tourism has the potency of going the highest generator of foreign currency. GIS and Tourism: GIS is used in touristry sector in different ways in the different states. In general the most common usage of GIS in touristry is location analysis and related to transport and adjustment. In general the undermentioned consequences can be achieved by questions in GIS Design and Application for Tourism: Determination of of import and necessary topographic points for touristry. Determination of historical and tourist topographic points. Determination of the best suited hotel. Determination of the optimal program for sightseeing topographic points Determination of the shortest distance between the selected topographic points The usage and application of GIS in the touristry sector can be divided into the undermentioned three classs: 1 ) Tourism planning 2 ) Tourism development and research 3 ) Tourism selling For touristry, one of the most of import things is the local map of the tourer site. Map and GIS is closely related to each other. Maps with relevant spacial informations can be produced with GIS. It can demo the of import characteristics, attractive sites, possible paths of travel, location of hotels, eating houses, bars, shopping installations with inside informations. General information from this map and paths for travel can be used by tourers in choosing their finishs and further planning for travel and stay. For touristry path is besides of import. To make that GIS base map is besides helpful. Application of GIS in Tourism: Some examples- In IRAN: Esfahan Council of Tourism in IRAN investigated the usage of GIS in Tourism Research in hive awaying, pull stringsing and analysing the voluminous touristry informations and study carried out. To make this research, the Esfahan council of touristry in IRAN conducted some stairss which are narrated shortly- Network Analysis: By and large a web is a set of additive characteristics. Common illustrations of webs include main roads, railroads, metropolis streets, rivers, transit paths ( e.g. , theodolite, school coachs, refuse aggregation, and mail bringing ) , and public-service corporation distribution systems ( e.g. , electricity, telephone, H2O supply, and sewerage ) . For the Esfahan council, they use GIS to make web analysis in the additive characteristics utilizing vector theoretical account of GIS. Network Allocation: One of the most of import procedures in the Planning and investing activities is web allotment. In other words, Network allotment is an analysis happening at the same clip of geographical entities and finding procedure. Network Routing: Network routing determines the optimum way along a additive web. The choice of the way can be based on legion standards, such as shortest distance, fastest path, no left turns and minimal cost. Network Tracing: Network following determines a peculiar way through the web In the design stage, after choosing a topographic point which is the most attractive topographic point for tourer, informations procedure and physical design carried out with the aid of ARC position 3.2 with web analysis extension and ARC info. ( www.esri.com ) . Boundary maps, current maps, orthophotos, in-between lines of roads and their name are used as graphical constituents of GIS Design and Application for Tourism in this instance. Middle lines of roads which have vector and graphical feature for web analysis, and historical and touristry topographic points and all of the geographical objects considered as necessary points for touristry were designed as point bed. Merely constructing bed was designed as polygon bed. Different beds for analysis has been used. There is general information on the entry demands to the state, the clime, regulations of the route and disease bar. ArcView web analyst is used to cipher the shortest path between topographic points and generate waies. This is printed for the tourers which help them to happen out their optimal finish. Distance between Parkss and hotels are besides included and the easier path is besides demoing which help the tourers who are driving and utilizing ain conveyance. From this farther optimum planning is possible which will assist to salvage clip and money every bit good. In GHANA: GIS has the ability to execute spacial analysis. This ability has been used in GHANA every bit good. Harmonizing to Daniel longmatey Simple analysis such as statistical sum-ups ( lower limits, upper limits, agencies, and amounts ) and analysis of inter-relationships between assorted touristry related variables could be carried out in a GIS environment. For illustration, the informations sets of historic memorials and roads could assist work out the job of happening all historic memorials along a primary route. In Ghana, GIS is used for cartographic development with the aid of ESRI ARC Info and ARC GIS package. Labels and suited in writing symbols were assigned to the assorted characteristics for easy classification, designation and visual image. Facilities such as roads were besides classified. A composite digital tourer map was therefore produced. With the digital tourer map a tourer can time on a peculiar location and that peculiar point will demo the inside informations of that location. Even the distance measuring, other suited attractive topographic points can be found in that digital tourer map. Use of GIS engineering for touristry planning offers a group of advantages in informations certification and processing that is found in Ghana- Thematic mapmaking can be generated in a fast and cheap manner. Maps are produced in variable graduated tables harmonizing to different sorts of users. Information can be updated fast and easy. To do applications with basic information and to bring forth new information through variable combination is faster and cheaper that traversing informations in manual manner. They can demo consequences in cartographic, statistical, or table signifier. Mistakes can be corrected dinamically, salvaging the clip and stuff that they would be if corrections need to be done on printed maps or tabular arraies. Mapmaking can be presented better and more truth. Information can be integrated easy, through automated relation between different database that describes the same geographic infinite harmonizing different subjects. In Turkey: The Tourism Information and Promotion System ( TIPS ) was developed in Turkey based on a GIS application. The three following entities can utilize the TIPS. They are- Persons on any group of people going to Turkey All travel agents and Tour operators In this system, Digital Tourist Information Bank and a elaborate map established demoing all major, secondary roads, and other roads that provide entree to major historic and natural sites, political boundaries, all metropoliss, important colonies, historical and archeological sites, National Parks, watering place, touristry Centres ( sea athleticss, winter athleticss, etc. ) , ports of entry, and physical boundaries such as sea, lake, and river as separate beds. With the ARC View Network analyst question and expose the shortest distance and travel clip between the specified beginning and finish points are calculated as all the route sections are given distances in stat mis and kilometers, with route quality and degree of service. For illustration, a tourer who wants to travel to Ephesus from Istanbul will come in the names of the two locations, either as a text or by snaping on the map, and the shortest and safest path will be displayed on the screen. Besides, other topographic points of involvement and service countries along that path will be displayed, demoing more possibilities for way stations. It is besides planned to come in the names, references and telephone Numberss of the manager services, air passages, and railroads ( Adil, A. et. Al. ) . Site programs of of import historic, natural sites, street maps of major metropoliss are prepared in a digital format supplying maps demoing streets, location of museums, hotels, eating houses, convention centres, infirmaries, train Stationss, tube Stationss, which allow reference matching and web analysis. ArcView GIS Network Analyst extension gives an chance to set together a full, comprehensive image of the roads in footings of distance, clip, shortest distance, cost, propinquity to certain areas/points, route conditions, degree of service, travel limitations, etc.ArcView GIS provides a holistic position of beds, full information about the state, and entree to broad assortment of hotlinks such as text, image, sound, etc. ( Adil, A. et. Al. ) . In Zimbabwe: In Zimbabwe, GIS has been used to make market research for touristry. Sing touristry as a concern this research has been carried out. It was tried to happen out the following questions utilizing GIS in the touristry sector of Zimbabwe- _ Where clients are located _ The possible turnover of the concern _ Where can farther develop and how For market growing and concern development, it is necessary to cognize the location of the bing clients, the bend over point of the concern and peculiarly which side is in perfect form for farther development at that peculiar clip. In Zulia province, Venezuela: The Tourism Planning Geographic Information System ( SIGTUR, abbreviation in Spanish ) was established in 1997 by the six professors of the University of Zulia based on GIS. SIGTUR usage Esri ArcView GIS with Network Analyst extension and other with 3dAnalyst extension, to make complex thematic maps and on the other manus Esri ArcExplorer is used to back up to confer withing urban research activities.SIGTUR is based on three sort of procedure, uniting automated bids and know-how operators knowledge ( www.proceedings.esri.com ) : 1. Documentation. This procedure feeds GIS system with graphical and prenominal information. Recolection, by in-site enrollment, telephonic studies and institutional information. Systematization, telling information harmonizing subsystem variables. Transcription, digitising. 2. Analysis. It use GIS capacities to cipher relation phenomena between urban variables. Concentration, using statistical analysis to number sum of units per locality or urban country. Proximity, utilizing buffers to cipher influence countries from punctual, direct or polygonal attracting sites. Accessibility, utilizing web analyst to determinate best paths to interesting sites. 3. Consequences. It search the boundary line and making of possible touristry sites. Direct concluding products- Thematic maps by facet, by screen or ready-to-print Database studies, by hunt standards or stock list end products Indirect sub-products Digital maps, utile as consumables for another application. From the above mentioned illustrations, application of GIS in touristry can non be understand to the full. There are many other ways of using GIS in touristry sectors in many ways. If it is chalked out the application of GIS in touristry the undermentioned subjects are found. Data entry, storage and use, Map production, Database direction, Data questions and hunts, Spatial analysis, Spatial mold, Decision support, Location, Condition, Routing, Identify most suited locations for development, Measuring touristry impacts at the different parts, Visitor management/flows, Analyze relationships, Assess possible impacts of touristry development etc. Decision: Tourism finishs are normally characterized by three different landscape characteristics: points, lines, and polygons. Point characteristics are single tourer attractive forces, for illustration, a characteristic in a park, or a historic site along the main road. Coastal beaches and resorts frequently follow a additive form, while large subject Parkss or natural Parkss are features of a polygon characteristic. These locational properties are indispensable to a geographic information system. It is evident that GIS has enormous potency for application in touristry. GIS has been applied in many subjects including geographics, forestry, urban planning, and environmental surveies. Similarly, touristry is a topic related to geographers, economic experts, concern, conservationists, contrivers, anthropologists, and archeologists. For that the potency for GIS applications in touristry is important. Its usage in environmental planning is quickly increasing. Tourism is an activity extremely dependant on environmental resources. Now eco-tourism is going more popular instead than traditional touristry. On the other manus, the strength of touristry planning can be enhanced by GIS applications. So as whole it can be said that GIS is a utile and efficient tool for sustainable touristry development and for touristry research every bit good.
