To what extent did the invasion of Iraq in March 2003 signify a change Essay

To what extent did the invasion of Iraq in March 2003 signify a change in the way that force is used in international relations - Essay Example An urge to conduct an investigation in Iraq emerged when the Iraq government attacked US in the year in 2001. The US government felt vulnerable, especially after this attack that is believed to have been an operation of Al-Qaeda, one of the rogue groups in Iraq. The US government felt vulnerable and feared that the Iraq government would use the weapons of mass destruction against the US government. Another fear was that with these weapons available in Iraq, the Al-Qaeda group would access them and conduct a more severe attack than one of 2001. Thus, the US felt the need to launch an effective operation to inspect and disarm the Iraq government of any weapons of mass destruction that they could be holding. Although many felt that the rumour on the presence of weapons of mass destruction in Iraq was a mere speculation, the UN team engaged a powerful gear to unravel the truth of the matter. In 2002, the plan of inspection was underway and there was light that the Iraq government would comply with the inspection plan. On the other hand, the US government felt that this process was slow and that there was a need to hasten the process to avoid the looming threat that the weapons would be used against the US. In essence, they felt that the UN and the international bodies were slow in neutralizing a threat that would have dire consequences on US. However, the international body insisted that it was important to give Iraq sometime to comply with the demands of the inspection as there was still hope that the process would succeed. Even a number of the US allies accepted that this was not a time of war as there was no any evidence that there was any destructive weapon. Despite the efforts of many countries and international bodies to stop US from engaging Iraq in a war, the US government declared a war in the country and organized their troops

Principle of teaching Essay Maintaining an environment for ï ¬ rst-class higher education Nine educational principles underpin the University of Melbourne’s teaching and learning objectives. These principles represent the shared view within the University of the processes and conditions that contribute to ï ¬ rst-class higher education. The nine principles were ï ¬ rst adopted by the University’s Academic Board in 2002. This renewed edition of the document reï ¬â€šects the bold changes the University has undergone since then with the implementation of the Melbourne Model. Many elements of the nine principles are embedded in the philosophy of the Melbourne Model. The provision of a cohort experience, the breadth component, research-led teaching, attention to the physical and intellectual learning environment, knowledge transfer opportunities: these features of the Melbourne Model incorporate the nine principles on a structural level, reinforcing their importance and the University’s commitment to them. Aspects of the principles guiding knowledge transfer with regard to teaching and learning are the most signiï ¬ cant additions and while they are embedded throughout the document, they are particularly concentrated in principles two and seven. In principle two the interrelations between research, knowledge transfer and teaching and learning are described while in principle seven the practical elements of embedding knowledge transfer in teaching and learning are discussed. Nine guiding principles 1. An atmosphere of intellectual excitement 2. An intensive research and knowledge transfer culture permeating all teaching and learning activities 3. A vibrant and embracing social context 4. An international and culturally diverse learning environment 5. Explicit concern and support for individual development 6. Clear academic expectations and standards 7 Learning cycles of experimentation, feedback and assessment . 8. Premium quality learning spaces, resources and technologies 9. An adaptive curriculum The nine guiding principles are interrelated and interdependent. Some relate to the broad intellectual environment of the University while others describe speciï ¬ c components of the teaching and learning process. Together, these principles reï ¬â€šect the balance of evidence in the research literature on the conditions under which student learning thrives. Each principle has a direct bearing on the quality of students’ intellectual development and their overall experience of university life and beyond as they embark on a process of lifelong learning, regardless of whether they come to the University as undergraduate, postgraduate coursework or postgraduate research students. Generic statements of beliefs, values and practices cannot completely capture the diversity and variation present in a large and complex University. However, the underlying principles presented in this document hold true despite variations across the disciplines in traditions of scholarship and in philosophies and approaches towards teaching and learning. Indeed, the nine principles described here support the process of interdisciplinary learning encouraged by the Melbourne Model: they provide a framework under which teachers from different backgrounds and disciplines can work together to plan, develop and provide coherent interdisciplinary learning experiences for students. The ultimate objective of the University of Melbourne’s teaching and learning programs is to prepare graduates with distinctive attributes — described in the next section — that enable them to contribute to our ever-changing global context in a meaningful and positive way. The purpose of the present document is to guide the maintenance and enhancement of teaching and learning standards that serve this end. It is a statement of what the University community values. As such, it has aspirational qualities and the suggestions for good practice offered provide laudable benchmarks to which the University is committed within the availability of resources. Responsibilities The maintenance of the University of Melbourne’s teaching and learning environment is the responsibility of the whole institution. This document identiï ¬ es various University, Faculty and individual responsibilities, though not all of the detailed implications apply equally to all members of the University community. The Academic Board is responsible to the University Council for the development of academic policy and the supervision of all academic activities of the University of Melbourne, including the preservation of high standards in teaching and research. It has core quality assurance functions, including the approval of selection criteria, the monitoring of student progress, the approval of new and changed courses, and the monitoring of the quality of teaching and learning. The Provost is responsible to the Vice-Chancellor for the conduct, coordination, and quality of the University’s academic programs and the planning of their future development. The Provost provides academic leadership, working in close collaboration with the Academic Board, deans and professional staff to ensure the alignment of accountability, budgets and initiatives in the delivery of academic programs and consistent, high quality student support. The Academic Board and Provost together ensure that the University: †¢ recognises and rewards excellence in teaching through its policies in staff recruitment, selection and promotion criteria; †¢ provides extensive opportunities for professional development in teaching and learning; †¢ supports and promotes research-led teaching; †¢ develops and maintains high quality teaching and learning spaces and resources; †¢ places high importance on the place of knowledge transfer activities in making its degrees relevant and distinctive and supports its staff and students in pursuing such activities; †¢ encourages and supports innovative approaches to teaching and learning, including through the application of advancements in information and communications technology; and †¢ provides mechanisms for on-going curriculum review involving all stakeholders (students, community, industry, professional associations, and academics) of the content, structure and delivery of courses and the learning experiences of students. The University is committed to the scholarship of teaching in the belief that academic staff in a research-led environment should apply scholarly principles to teaching and to the leadership of student learning. In practice, the scholarship of teaching involves academic staff being familiar with and drawing on research into the relationship between teaching and student learning. It also involves evaluating and reï ¬â€šecting on the effects on student learning of curriculum design, knowledge transfer activities, teaching styles and approaches to assessment. The present document is designed to support consideration of the University’s obligations in terms of the scholarship of teaching and to assist in the review and enhancement of the quality of personal teaching practices. Students have responsibilities as well for the quality of teaching and learning. The effectiveness of a higher education environment cannot be expressed simply in terms of the challenge, facilitation, support and resources provided by teaching staff and the University as an institution. Students have complementary responsibilities. Students have responsibilities for their personal progress through their level of engagement, commitment and time devoted to study. Students also have obligations to contribute to the creation and maintenance of an effective overall teaching and learning environment. These obligations include: †¢ collaborating with other students in learning; †¢ contributing to the University community and participating in life beyond the classroom; †¢ developing a capacity for tolerating complexity and, where appropriate, ambiguity; †¢ respecting the viewpoints of others; †¢ being reï ¬â€šective, creative, open-minded and receptive to new ideas; †¢ actively participating in discussion and debate; †¢ seeking support and guidance from staff when necessary; †¢ accepting the responsibility to move towards intellectual independence; †¢ being familiar with the Graduate Attributes and consciously striving to acquire them; †¢ respecting and complying with the conventions of academic scholarship, especially with regard to the authorship of ideas; and †¢ providing considered feedback to the University and its staff on the quality of teaching and University services. The Attributes of University of Melbourne Graduates The University of Melbourne Graduate Attributes are more than simply an aspirational vision of what the University hopes students might become during their candidature. They can be used practically to guide the planning and development of teaching, knowledge transfer and research to ensure the University’s students acquire the experience, skills and knowledge necessary for graduates in today’s complex global environment. Graduate Attributes The Melbourne Experience enables graduates to become: Academically excellent Graduates will be expected to: †¢ have a strong sense of intellectual integrity and the ethics of scholarship †¢ have in-depth knowledge of their specialist discipline(s) †¢ reach a high level of achievement in writing, generic research activities, problem-solving and communication †¢ be critical and creative thinkers, with an aptitude for continued self-directed learning †¢ be adept at learning in a range of ways, including through information and communication technologies Knowledgeable across disciplines Graduates will be expected to: †¢ examine critically, synthesise and evaluate knowledge across a broad range of disciplines †¢ expand their analytical and cognitive skills through learning experiences in diverse subjects †¢ have the capacity to participate fully in collaborative learning and to confront unfamiliar problems †¢ have a set of ï ¬â€šexible and transferable skills for different types of employment Leaders in communities Graduates will be expected to: †¢ initiate and implement constructive change in their communities, including professions and workplaces †¢ have excellent interpersonal and decision-making skills, including an awareness of personal strengths and limitations †¢ mentor future generations of learners †¢ engage in meaningful public discourse, with a profound awareness of community needs Attuned to cultural diversity Graduates will be expected to: †¢ value different cultures †¢ be well-informed citizens able to contribute to their communities wherever they choose to live and work †¢ have an understanding of the social and cultural diversity in our community †¢ respect indigenous knowledge, cultures and values Active global citizens Graduates will be expected to: †¢ accept social and civic responsibilities †¢ be advocates for improving the sustainability of the environment †¢ have a broad global understanding, with a high regard for human rights, equity and ethics Principle 1: An atmosphere of intellectual excitement The excitement of ideas is the catalyst for learning Intellectual excitement is probably the most powerful motivating force for students and teachers alike. Effective university teachers are passionate about ideas. They stimulate the curiosity of their students, channel it within structured frameworks, and reveal their own intellectual interests. While students have strong vocational reasons for enrolling in courses of study, unless they are genuinely interested in what they are studying their chances of success are low. Pascarella and Terenzini’s (1998) meta-analysis of research on the effects of university education concluded that the evidence unequivocally indicates that greater learning and cognitive development occur when students are closely engaged and involved with the subjects they are studying. The research evidence shows that most undergraduates commence university with a strong interest and curiosity in the ï ¬ eld they have selected, providing a strong foundation on which to build. A Centre for the Study of Higher Education study of applicants for university places (James, Baldwin McInnis, 1999) showed that intrinsic interest in the area of knowledge was among the most important inï ¬â€šuences on their choice of a university course. University of Melbourne graduates conï ¬ rm these sentiments. When asked for their views of their educational experience at the University some time after graduation, graduates consistently stress the inï ¬â€šuence of staff who were excited about ideas, and the importance to them of studying in an atmosphere of intellectual stimulation and discovery. Part of fostering an atmosphere of intellectual excitement in students includes providing them with stimulating experiences that enable them to realise the value and knowledge of their skills in external settings. Some of these experiences will involve activities in the classroom – such as problem and project-based approaches and involvement of community and industry participants in class activities – but many will take students beyond the University’s campuses, to include such activities as ï ¬ eld and industry placements or internships, on-location subject delivery and student exchange programs. As well as providing students with a vibrant intellectual experience, embedded knowledge transfer activities allow students to understand and analyse the social, cultural and economic contexts in which their own knowledge acquisition is situated as well as help them realise their capacity, responsibility and opportunity for current and future knowledge transfer. Implications for practice †¢ Subjects are planned and presented in terms of ideas, theories and concepts. †¢ Conï ¬â€šicting theories and approaches are incorporated into courses to stimulate discussion and debate. †¢ Courses are designed to foster an understanding of the legal, political, social, economic, cultural and environmental contexts for practice in national and international settings, and of codes of conduct and the ethics of practice. †¢ Knowledge is presented in terms of broader contexts — intellectual, social, political, historical — to help students understand the signiï ¬ cance of what they are studying. †¢ Students’ personal engagement is fostered by teaching which encourages them to relate their learning to their own experiences. †¢ Staff convey enthusiasm for the subject matter and work to provoke students’ curiosity. †¢ Courses and subjects are revised regularly to incorporate new theories and approaches. †¢ Staff model the excitement of intellectual exploration when working with students. †¢ Students are given opportunities to make discoveries for themselves and creativity is rewarded. †¢ Innovative approaches to teaching and learning are incorporated into existing courses so that necessary, ‘base-line’ learning is revitalised. †¢ The University provides resources and activities to allow students to develop their interests beyond the experiences provided within their courses. Principle 2: An intensive research and knowledge transfer culture permeating all teaching and learning activities A climate of inquiry and respect for knowledge and the processes of knowledge creation and transfer shapes the essential character of the education offered by a research-led University It is a basic conviction within the University of Melbourne that the University’s research activities and research culture must infuse, inform and enhance all aspects of undergraduate and postgraduate teaching and learning. Across all disciplines and across all study levels, education in a research-led university develops its distinctive character from an understanding of and respect for existing knowledge and the traditions of scholarship in particular ï ¬ elds, recognition of the provisional nature of this knowledge, and familiarity with the processes involved in the ongoing creation of new knowledge. Historically, research and teaching have always been considered in symbiotic relationship at the University of Melbourne; however, the Melbourne Model introduced a crucial third strand to this relationship: knowledge transfer. In the context of teaching and learning, knowledge transfer experiences â€Å"underpin the development of high levels of skill and ï ¬â€šexibility in problem-solving, in creative contributions in the workplace, in understanding, assessing and initiating innovative contributions to community needs and in promoting and developing egalitarian ideals and social, civic, ethical and environmental responsibility† (Curriculum Commission 2006: 35). Research thus lays the foundations for knowledge transfer, but knowledge transfer, in turn, elucidates the signiï ¬ cance of research by placing the knowledge it produces in context. The process of knowledge transfer is also inherently two-way: as students engage in activities such as substantial ï ¬ eld-based projects or placements and internships, so too they engage with industry, the professions and the broader community, taking their knowledge – which has its origins in research and experiences to the world. Not all students are directly involved in research activity, but the University has a strong commitment to the teaching-research nexus, and aims for all undergraduate and postgraduate students to beneï ¬ t from being taught or supervised by active researchers, from studying a curriculum informed by the latest research developments, and from learning in a research-led environment. Training in research skills is fundamental to students acquiring the skills of critical thinking. As Baldwin (2005) has shown, there are myriad opportunities and methods for teachers to incorporate research in teaching, a process fundamental to students ’learning how to learn’; that is, how to effectively process and apply both their present understandings and giving them a framework and skills for using the knowledge they will acquire in future. It is essential, therefore, that teaching staff are learners too and that their teaching is infused by their learning and their love of research and scholarship. The particular beneï ¬ ts for undergraduate students of an intensive research culture derive from experiencing the ‘latest story’ — curricula underpinned not only by the corpus of human knowledge in the particular ï ¬ eld but also by the latest research and scholarship — and from learning in an educational climate in which knowledge claims are viewed as fallible, ideas are questioned and inquiry-based learning is given a high priority. Knowledge transfer adds yet another dimension, giving students the opportunity to see knowledge at work in social, economic and cultural context. Interdisciplinary learning and teaching can also provide students with unique perspectives and solid understandings of how knowledge is created and used. However, while interdisciplinarity should be embraced — underpinned by the maintenance of established quality assurance and evaluation processes — a strong disciplinary focus should, nonetheless, be preserved (Davies and Devlin 2007). A climate of respect for ideas and spirited inquiry in which theories and ideas are actively contested supports the development of critical thinkers and heightens student sensitivity to the history of the evolution of knowledge, the provisional nature of knowledge and the processes of knowledge renewal. Knowledge transfer adds a signiï ¬ cant new dimension to curriculum design and delivery, encouraging innovation and dynamism in approaches to teaching. It is essential, however, that the overriding principles of coherence and appropriateness – within both a subject and the broader course of study itself – are maintained; that is, that knowledge transfer activities are embedded, relevant and targeted to the overarching goals of the degree. Ultimately, exposure to the interdependence of research, learning and teaching and knowledge transfer provides students with the opportunity to acquire the graduate attributes (see page 4), and to use them in practice. Implications for practice †¢ Teachers model intellectual engagement in the discipline, including an approach of analytical scepticism in the evaluation of all research. †¢ Current research and consultancy experiences are directly incorporated into teaching content and approaches. †¢ Teachers demonstrate that they value lifelong learning, and foster in students an awareness that it will be essential in their professional and personal lives. †¢ Students are trained in the research skills of particular disciplines, but that they are also aware of the possibilities for and challenges in interdisciplinary and multidisciplinary research; †¢ Students are made aware of the traditions of scholarship in particular ï ¬ elds, the history of knowledge development, and the body of existing knowledge. †¢ Teachers keep abreast of current developments in their own and related disciplines and incorporate this knowledge into their teaching. †¢ Evidence-based or scholarship-informed practice is emphasized, and students gain experience in critically evaluating and contributing to the evidence base, or in critically assessing and contributing to the scholarly discourse on practice. †¢ Research students are exposed to current research through involvement in staff seminars and conferences. †¢ Students are made aware of the questioning of paradigms that is central to the development of knowledge. †¢ Staff demonstrate a commitment to professional values and ethical practice in the conduct of research. †¢ Students conducting research are made to feel part of the community of researchers while they are being trained in its procedures and values. †¢ Staff adopt a scholarly, evidence-based approach to the decisions made about curriculum design, teaching approaches and assessment methods. †¢ As appropriate, staff conduct research into the effects of teaching on student learning. †¢ Staff demonstrate a willingness to revise their own views and admit error, and encourage this attitude in students. †¢ Students are enabled to see the relevance of research to current practice through exposure to experienced practitioners, e-enabled case experiences, ï ¬ eld trips and other in situ learning experiences.

Nature versus Nurture :: Genes vs Environment

Abstract The paper covers the debate of nature versus nurture. Within the paper there is an introduction in which the hypothesis is given and a literature review that provides the reader with previous studies done with nature versus nurture. The methods, results, discussion and recommendations from the research study are also provided within the paper. Introduction and literature review The research question is: When comparing Nature verses Nurture in children which one is stronger than the other? The hypothesis is: Nature has a stronger correlation than nurture when it comes to individual differences between males and females. There is a big controversy between whether inherited genes or the environment influences and affect our personality, development, behavior, intelligence and ability. This controversy is most often recognized as the nature verses nurture conflict. Some people believe that it is strictly genes that affect our ways of life, others believe that it is the environment that affects us, and some believe that both of these influence us. A wide variety of characteristics have been considered in such debates, including personality, sexual orientation, gender identity, political orientation, intelligence, and propensity for violence or criminality (Wright, 1998). Human nature is the range of human behaviors that is believed to be innate rather than learned. There is much debate over which behaviors are innate and which are learned, and whether or not this division applies equally to all individuals. Although "nurture" may have historically referred mainly to the care given to children by their parents, any environmental (not genetic) factor also would count as "nurture" in a contemporary nature versus nurture debate, including one's childhood friends, one's early experiences with television, and one's experience in the womb(Wright,1998). Indeed, a substantial source of environmental input to human nature may arise from external variations in prenatal development (Wright, 1998). Either way, social scientists have been struggling for centuries deciding whether our personalities are born or made. Tests are done often on identical twins that were separated to see how they are influenced. In the past twenty years, it has been discovered that there is a genetic component to about every human trait and behavior (Pinker, 2002). However, genetic influence on traits and behavior is partial because genetics account on average for half of the variation of most traits (Pinker, 2002). Researchers are finding that the balance between genetic and environmental influences for certain traits change as people get older (Pinker, 2002).

Comparative Essay between La Goulue & Les Girard

The city of lights was all about fun and the nightlife during the 19th century. Fortunately enough, Jules Cheerer and Henry De Toulouse-Ululate were able to perfectly capture the essence of Parish's blooming nightlife through their posters. Generally speaking, both posters are the same style, however, each artist was able to create different visual effects and atmospheric perspective using their own aesthetic sense. In this situation, both posters are advertising to the viewer the exhilarating nightlife n Parisian cabarets back in the 19th century.Yet, Latter's poster managed to capture a distinctive and sensual atmosphere compared to Cheerer's joyful atmosphere. Louise Weber, the female dancer In Latter's poster, can be seen performing the provocative cancan dance, which exposes her undergarments as she kicks her legs. The audience in the background looks as if they are interacting with the dancer even if they are Just watching her. Meanwhile, the dancers in Cheerer's poster are che erfully dancing with their hands in the air with no audience around.Even though the figures depicted in both posters are 2-dimensional, Latter's poster has more depth because of the way he places his figures through out different layers. The male dancer and the unusual yellow shape on the left dominate the foreground. The main focus of this image is the female figure placed in the center and between the foreground and background. The contrasting silhouettes behind her further highlight the focus on her. The figure in the middle of Cheerer's poster is wearing a vibrant red dress, which easily catches the viewer's eye even though two lively nagging men overlap her.The two male figures are framing the woman in the middle with their legs. The soft, textured, and plain background contrast with the red and black of the flat figures and brings them out. There Is minimal use of shading, but instead, crisp black lines outline the figures, giving the illustration a flat look. Nothing seems to have a definite structure since there is no sense of strong, angular and straight lines but instead, the lines look more organic as seen with the text and figures.This poster might look a bit symmetrical but the artist drew both men who re facing each other with slight differences to add more to the unstructured and organic feel of the Image. One of the main features of Less Gerard is how the text and illustrations can be seen interacting with one another. One figure looks like as if he is standing on the letter G while the other figure has his legs passing through the letter o. The small 3rd figure relationship can be seen between the text and illustrations in the way they were rendered. The have a long pointed form.For example, the tip â€Å"A† in â€Å"Less Gerard mimics the man's foot. The text was customized by the artist hence the similarities between the illustrations and the text. Ululate uses several different fonts in his poster. In this case, Latter's font does n ot interact with the figures in the poster and does not look like it was drawn by hand but instead is placed on top of the figures with low opacity. The other text that is dominating the top part of the poster has more bold colors and is outlined in black, which balances out the heavy image filled bottom part of the poster.Since Ululate was influenced by Cheerer, the similarities in their work. Ululate also chose to work using the same medium, lithography, which is why their work has strong bold colors. There is no doubt that both artists were influenced by the Japanese style, as it is evident in most of their work. The flat planes of color, 2-dimensional figures, and crisp black contour lines are elements from the Kikuyu-e woodblock print style. Latter's composition of figures overlapping each other is also derived from the Japanese art style. On the other hand, the composition in Cheerer's poster is almost symmetrical.This shows us that even though Ululate was influenced by Cheere r, Ululate had a better understanding of Japanese art and was able to fuse that with his own work in order to produce his own style. In conclusion, the posters may seem to be very similar in style; nevertheless, slight differences between those posters do exist and those differences showcase each artist's unique touch. This demonstrates the endless cycle of an artist influencing another artist who in turn modifies and develops what he learned in order to develop his own style and that may even result in a whole new art movement.

Music-Induced Affect as Treatment of Elderly Depression Essay

Abstract   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Depression in elderly patients is one of the most prevalent psychological problems today. However, research and knowledge regarding this subject is limited and those involved in the application of this knowledge to help elderly individuals experiencing depression are lacking in efficient strategies and training. This paper aims to explore the efficacy of inducing positive affect through music as a strategy in treating depression in elderly individuals. The paper focuses on the effectiveness of music alone as tool in treating depression based on its capability to induce positive affect. It is hypothesized that positive affect continuously induced via music within a set time-period will lessen signs of depression. Introduction Depression has recently been recognized as one of main psychological problems facing society today. Literature shows that treatment of depression needs to be specialized in terms of the population it addresses. Certain groups, such as adolescents, respond to certain treatments differently when compared to another group, such as the elderly. (Aryan & Alvidres, 2001; Von Kroff et al, 2001) Depression among the elderly has specifically been found to be rampant and mostly unchecked mainly due to the fact that it was regarded earlier on as a normal step in an individual’s aging. (Casey, 1994) The need for further research on the subject is stressed by the fact that treatments and solutions for depression among elderly individuals are studied only in areas wherein a majority of the population is in the late stages of life. (Bramesfeld, 2003) Also, research has shown that general practitioners involved in treating depression in the elderly need to have more training and information on how best to handle depression in older patients. (Rothera et al, 2002) Diagnosis of depression is also a problem with 70-90% of depressed elderly patients going undiagnosed. (Koenig, 1999) A new strategy being researched for its effectiveness in treating depression employs the use of music techniques. Hendricks et al (1999) showed the potency of music in treating adolescent depression mainly because of its ability to inspire a change in the individual’s emotions. Hanser & Thomson (1994) and Hanser (1990) studies have also shown promise in the use of music techniques to treat depression in older individuals. This paper aims to validate these previous studies but will focus only on the musical aspect of the treatment. Previous research included exercise, muscle relaxation techniques, and recall of experiences which could have confounded the results of the previous studies attesting to the effectiveness of music techniques. Research Question   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     The goal of this paper is to determine whether there is a significant relationship between music-induced affect and depression. Can positive affect induced by music reduce depression? It is hypothesized that positive music-induced affect has a significant negative relationship with depression. Methods   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The design of the study is experimental and random. Specifically, it makes use of a 2Ãâ€"2 between-subjects factorial design. One variable will be the music-induced affect which will have two levels in the experiment, presence and absence of music-induced affect. Negative music-induced affect will not be used for ethical reasons. The other variable will be the test scores of the participants assessing the intensity of their depression. This will have two levels, test scores prior to the application of the music technique and test scores acquired after application. The two variables contribute tot eh 2Ãâ€"2 factorial design. (Mann, 1949) Setting   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The study will be conducted in a laboratory setting within primary care facilities from which the participants will be gathered. Performing the experiment in a primary care facility will be more convenient especially because the participants involved are elderly individuals. The laboratory setting will control for confounding variables that could be present in a real environment. Population   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The research sample will be composed of individuals from age 65 onwards coming from primary care facilities and who have been diagnosed with depression (ranging from mild to severe). This is to avoid ethical and scientific concerns regarding clinically-induced depression. Data Collection The independent variable is the positive music-induced affect will be measured with the State Form of the Multiple Affect Adjective Check List-Revised (MAACL-R). (Zuckerman & Lubin, 1985) The depression level, the dependent variable, of the participants will be measured with the Beck Depression Inventory (BDI). (Beck et al, 1961) Participants will be randomly assigned to two groups. The experimental group will be administered with music sessions aimed at inducing positive affect. The music will be pre-tested on a different set of participants also with depression to check its validity in inducing positive affect. The control group will not be administered with music sessions and will only be administered the Beck Depression Inventory at the start and at the end of the experimentation period.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The experimental group will be administered the selected music once daily for a duration of four weeks. During the sessions, participants of the experimental set-up will be asked to clear their minds and to concentrate only on the music being played. The State Form of the Multiple Affect Adjective Check List-Revised will be administered before and after each session to ensure that positive affect was induced. The Beck Depression Inventory will also be administered to this group at the start and end of the four-week experimentation period to document depression levels. Data Analysis   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Collected data will be analyzed statistically with the use of a one-way analysis of variance (one-way ANOVA). The computed marginal means in the ANOVA will be the determining statistical value indicating the effect of positive music-induced affect on depression scores with the Beck Depression Inventory. Conclusion   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Music as a technique employed in treating depression will provide healthcare workers and low-income families with a relatively cost-free strategy of helping elderly individuals experiencing depression. This is also a technique that doesn’t require much training or medical expertise in its administration. All one would need in order to be able to administer this technique is knowledge as to which music selections are prescribed and certified to induce positive affect. This technique, because of its simplicity and speed of application, could also be used as a supplementary strategy to medication, counseling and psychotherapies being employed to treat depression in elderly patients.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The research, however, has many limitations. The range of elderly individuals that will be available for experimentation will only be confined to a specific locality. Time constraints will also be an issue. Further study should be conducted on a larger sample size and over a longer experimentation period. Different music styles and variations can also be checked to ascertain maximum effectiveness of the treatment. Gender could also be checked as a factor.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Depression is indeed a psychological problem that afflicts today’s elderly individuals. Research regarding effective techniques has to be continued and expanded in order for healthcare workers to be able to best address this growing problem. References Arean, P., & Alvidrez, J. (2001).

Describe the role of Lipids in Living Organisms Essays

Describe the role of Lipids in Living Organisms Essays Describe the role of Lipids in Living Organisms Paper Describe the role of Lipids in Living Organisms Paper Lipids are a large and varied group of organic compounds, (3) which are insoluble in water, but soluble in organic solvents such as ethanol and ether. (7). The molecules contain atoms of hydrogen, carbon and oxygen. The ratio of hydrogen to oxygen atoms is always greater than 2:1. (2)Triglycerides are fats and oils and are made when glycerol form condensation reactions with three fatty acids to produce ester bonds. (2). At 20à ¯Ã‚ ¿Ã‚ ½C fats are solids whereas oils are liquids. One of the major roles of lipids in organisms is the use of these fats as energy stores. Upon breakdown they yield 38 kJ/g of energy compared favourably with carbohydrates which yield 17 kJ/g, (3) so they therefore store twice as much energy than carbohydrates. Animals store fat when hibernating and fat is also found below the dermis of the skin of vertebrates where it serves as an insulator. (10). Plants usually store oils and a small mass for energy is used in plants where the dispersal of small seeds by w ind or insects is much easier. (9). Triglycerides are also compact, insoluble, can be stored at high concentrations, without requiring water as a solvent and are not mobilised as easily as carbohydrates, (5) which makes them long term energy stores. (5)Fats also act as shock absorbing layers. (2). This protects delicate organs such as the kidneys or the heart from physical damage. Aquatic mammals such as whales have extremely thick subcutaneous fat, called blubber. (3). The blubber is extremely important in thermoregulation as underwater hair is ineffective as an insulation because it cannot trap water in the same way as it can air. (10). Therefore as it is a poor conductor of heat, the layer of fat under the skin of aquatic mammals helps them to keep warm in cold climates. Fats aid buoyancy in aquatic mammals because they are less dense than water. This is especially true in vertebrates such as aquatic birds. (2)Lipids are used for electrical insulation in Schwann cells. The membra nes of Schwann cells are largely composed of lipid and they do not contain the protein channels. (9). The Schwann cells produce the fatty material myelin that surrounds the axons of many mammalian nerve cells. (6)Triacylglycerols also release twice as much water as do carbohydrates when oxidised in respiration. (5). A more indirect role of triacylglycerols is the use of their metabolic water, this is the water produced from their oxidation. (5). This metabolic water is of vital importance, which include the development of very young reptiles when enclosed in eggshells or the daily metabolisms of animals such as camels, which live in habitats where water is scarce. (5). Triglycerides are also commonly used in waterproof coverings. (2). Oil coats animal skin to waterproof it along with fur and feathers so that water is repelled and the animals insulation is not affected.However, insects and plant leaves use wax to form a waxy cuticle, which prevents water loss by evaporation and trans piration. (9). The waxes are esters of fatty acids with long chain alcohols other than glycerols. (10). Exoskeletons may also be coated with it. Saturated fatty acids that have no carbon-carbon double bonds have a high melting point and are found in animals whereas unsaturated fatty acids with one or more double bonds have lower melting points and are found in plants. (4). These fatty acids are also used to derive plant scents, which attract insects and aid pollination.Phospholipids are lipids containing a phosphate group and are formed when one of the primary alcohol groups of glycerol (head) forms an ester with phosphoric acid (tail), instead of a fatty acid. (10). The presence of the phosphate group means that the charge on the head of the molecule is unevenly distributed. It is said to be polar and is attached to water. The head end of the molecule is described, as being hydrophilic (soluble in water). The hydrocarbon tails do not have this uneven charge distribution. They are t herefore non-polar and will not mix with water. The tail end of the molecule is described as being hydrophobic (insoluble). (4). The main role of phospholipids in living organisms is that they are a major component of membranes and it is these solubility characteristics, which are of extreme importance in cells because lipids tend to associate into non-polar groups and barriers, as in the cell membranes that form boundaries between and within cells. (8).Therefore, if phospholipids were placed in water, they would arrange themselves into a phospholipid bilayer where the tails point inward and the heads outwards. (7). This bilayer forms the basis of cell membranes. The membrane is partially permeable as water; water soluble and polar molecules cannot pass through whereas gases, lipids and non-polar molecules can. Other more minor roles of phospholipids in living organisms are in the transport of fat between gut and liver in mammalian digestion and as a source of acetylcholine. (5)Ster oids are lipids whose molecules contain four rings of carbon and hydrogen atoms with various side chains. (9). Steroids are common in all organisms, mainly as hormones. Phosphatidyl inositol (a phospholipid lacking the group esterified to the phosphate) acts to release inositol trisphosphate and diacylglycerol as intercellular second messengers to hormones. (1). Terpenes are common in plants as pigments whereas cholesterol is the most common in humans. From cholesterol are made the bile salts, the sex hormones and the hormones of the adrenal cortex, (5) aldosterone and cortisone. (10). A steroid closely related to cholesterol occurs in the human skin and is converted to vitamin D by the ultraviolet rays in the sunlight. (5)Lipids also lower the surface tension in the air breathing vertebrates to make breathing possible. (11)Therefore evolution development has facilitated the compartmentalisation of cells with the aid of phospholipids it can be considered as a vital compartment, whi ch has enabled complex development and variation with birds fro example. Such variation as buoyancy, insulation etc are brought about by triglycerides.

Death Speech- a Streetcar Named Desire Essays

Death Speech- a Streetcar Named Desire Essays Death Speech- a Streetcar Named Desire Paper Death Speech- a Streetcar Named Desire Paper Essay Topic: A Streetcar Named Desire Blanche’s death speech plays a vital role in the development of the play â€Å"A Streetcar named Desire†. In the monologue the tension between Blanche and Stella comes to a zenith as Blanch explodes with rage as she expresses her jealousy-driven feelings to Stella. In doing so Blanche reveals much more, including her unstable mental state, her emotional reaction to the lost of Belle Reve, and most importantly her preoccupation with the theme of death. One of the roles of this excerpt is to provide the background towards understanding Blanche, and the justifications for her mental state and actions. It is evident that in the past she belonged to a higher class where extravagance was common. But when her family in Belle Reve gradually died off, not only did she have to experience the pain of losing her loved ones, but she was also left with no money or financial aid to keep the estate and ultimately was forced to let it go. Blanche defends herself by figuratively saying that the grim reaper put up his tent right on her doorstep and that is how â€Å"it slipped through my (Blanche’s) fingers†. She even goes on to accuse Stella of dealing with the crisis by â€Å"ignoring† it and moving on, hence leaving Blanche to deal with an unbearable burden. This is most obvious when she rhetorically asks Stella, â€Å"I let the place go?† This quote aids in leading the audience to perceive that it was Stella that let the estate go by not trying to help the situation. To accentuate her point Blanche brings up the irony of her being â€Å"at the bed when they (her family) cried out hold me† while condemning Stella for being â€Å"In bed with your (Stella) Polak.† During the speech there are numerous indications that prove Blanche was deeply hurt by her experience at Belle Reve. Firstly, the seemingly unnecessary long explanation in itself demonstrates the importance of Belle Reve to Blanche. Secondly, the frustration and anger she expresses with Stella highlights the importance of their home to her. Throughout the piece Blanche repeats words and phrases many times underlining her fury. For example, at the beginning she says, â€Å"I, I, I†, in the middle she utters â€Å"I saw,  Saw! Saw!† and in the end cries â€Å"I let the place go!, I let the place go?† Thirdly, it seems as if Blanche is accusing Stella of blaming her for losing Belle Reve when in the book Stella simply asks about what happened. This becomes clear when Blanche reproaches Stella by telling her: â€Å"And you sit there telling me with your eyes that I let the place go† and â€Å"Yes accuse me! Sit and stare at me thinking I let the place go!† This sort of presumptuous attitude and thinking influences the reader to assume that Blanche is unable to let go. In addition when Blanche says â€Å"I took the blows in my face and body†¦Farther, Margret, Mother†¦had to be burnt like rubbish† she is also directly conveying her agony. It is clear that Tennessee Williams carefully crafted this specific speech to introduce the theme of death, of which is recurrent in the course of the play. He makes sure to describe the devastation of having to deal with death through Blanche. â€Å"Funerals are quiet but deaths- not always†, â€Å"Sometimes they even cry out to you, ‘Don’t let me go’†, â€Å"Unless you were there at the bed when they cried out ‘Hold me’ you would never suspect there was a struggle for breath and breathing†, and â€Å"Why the Grim Reaper set up his tent on our doorstep† are some quotes that specifically and profoundly relate to the subject of Death. After reading these quotes and knowing that Tennessee Williams suffered from hypochondria (a cynical fear of death and diseases), one could decipher that Blanche’s mindset in this case is almost an emulation of the playwright himself. Due to the structure of the speech one could infer that the body language of Blanche goes from grief to anger to resentment and conclusively to disgust as she ends with that derogatory word â€Å"Polak†. As you can see Williams cleverly structures this one speech to portray and provide lots of valuable information about Blanche’s current state and past life; this in turn foreshadows her inner and external conflicts as the book progresses.
