Refractory Pain, Existential Suffering, And Palliative Care: Releasing An Unbearable Lightness Of Being, George P. Smith Ii

Scholarly Articles

Since the beginning of the hospice movement in 1967, “total pain management” has been the declared goal of hospice care. Palliating the whole person’s physical, psycho-social, and spiritual states or conditions is central to managing the pain which induces suffering. At the end-stage of life, an inextricable component of the ethics of adjusted care requires recognition of a fundamental right to avoid cruel and unusual suffering from terminal illness. This Article urges wider consideration and use of terminal sedation, or sedation until death, as an efficacious palliative treatment and as a reasonable medical procedure in order to safeguard the “right” …

Freshman Orientation Sessions Can Teach Incoming Students About Healthful Lifestyles, Marjorie Freedman, Jennifer Waldrop

Faculty Publications

Currently, 32% of college students are overweight or obese (body mass index ≥ 25),which is likely because many adolescents enter college with an elevated body mass index. Further, the transition from high school to college is associated with weight gain.On their own for the first time, freshmen have greater independence in all aspects of their lives. Increased independence, in turn, often results in changes in types of food and beverages consumed, and in overall eating and exercise patterns—changes that often affect weight gain. Although the popular media continues to perpetuate the “Freshman 15” myth, a recent meta-analysis reported freshmen gain, …

Point-Of-Selection Nutrition Information Influences Choice Of Portion Size In An All-You-Can-Eat University Dining Hall, Marjorie Freedman

Faculty Publications

There is limited information about point-of-selection nutrition information on food choices in all-you-can-eat university dining halls, where food cost is controlled. This pilot study examined effects of point-of-selection nutrition information (pictures of different portion sizes with corresponding nutrition information) on students' choice of French fries and salad dressing and portion size of French fries. Point-of-selection nutrition information significantly decreased percentage consuming “large” portions of French fries (p < 0.05) but had a limited effect on salad dressing choice. Surveys indicated that >99% of respondents (n = 359) recalled point-of-selection nutrition information; more females used point-of-selection nutrition information to determine portion size. Additional studies are needed to support these promising results.

Response To Violent Prone Female Adolescents: The Chicago Public School Approach, Marian E. Dozier

Dissertations

School violence has become increasingly more prevalent among adolescent females over the last ten years. As administrators, teachers, parents, and law enforcement officials try to control and decrease the number of violent incidents that occur in our schools, adolescent females continue to exhibit inappropriate and violent behavior at an alarming rate within our school communities. Adolescent females who behave badly have historically been overlooked or ignored, as girls have often been perceived as being incapable of demonstrating hostile conduct in an academic setting.

The purpose of this study was to investigate, describe, and analyze the frequency and nature of violent …

High School Transfer Student Transitions And Changes: Risk, Success, Failure, And The Vital Role Of The Counseling Curriculum, Benjamin M. Grais

Dissertations

Transfer students move schools for reasons other than promotion. They typically change residence and can change country, cultures and/or languages of instruction. These students have twice the risk of failure or not graduating and total 15-18% of the United States high school population. Effective means of improving success rates are needed. Achieving this goal requires first understanding the problem(s). Perhaps transfer students themselves can help us in our search. What can we learn from talking with transfer students?

For this mixed method study, the investigator interviewed ten diverse but carefully selected transfer students. The data revealed that transfer students describe …

Abstention To Consumption: The Development Of American Vegetarianism, 1817-1917, Adam Daniel Shprintzen

Dissertations

The history of vegetarianism in the United States has long been shrouded in myth, assumption and obfuscation. Vegetarianism as a vital ideological and political movement has often been presented--even by its proponents--as a product of twentieth century modernism, reflecting a rise in ethical consumer awareness. The historical record of the nineteenth century, however, tells a very different story. The notion that dietary choices could be connected with larger social and political goals was formulated during, and changed dramatically in the nineteenth century. This dissertation charts the rise and evolution of vegetarianism in the United States from 1817 until 1917.

Girls' Secondary Education In Uganda: Assessing Policy Within The Women's Empowerment Framework, Shelley Jones

Institute for Educational Development, East Africa

This paper makes the case that policies, such as the National Strategy for Girls' Education in Uganda (NSGE), intended to achieve gender equity in education for girls in developing countries, have limited relevance to, and impact on girls' actual educational experiences. Recent considerations of girls' education acknowledge that gender equity within education is more than access to schooling; it entails the cultivation of capabilities necessary for girls to participate fully, actively and equally in all aspects of their societies. Drawing on a longitudinal, ethnographic policy research case study with 15 Ugandan schoolgirls in rural Masaka District, Uganda, from August 2004 …

Stratigraphy And Palaeoenvironment Of The Paleocene/Eocene Boundary Interval In The Indus Basin, Pakistan, Muhammad Hanif

School of Geography, Earth and Environmental Sciences Theses

Marine sedimentary sections across the Paleocene/Eocene (P/E) boundary interval are preserved in the Patala Formation (Upper Indus Basin) and Dungan Formation (Lower Indus Basin), Pakistan. The P/E interval of the Patala Formation is composed of limestone and shale inter-beds indicating deposition on a carbonate platform. The analysis of larger foraminifera across the P/E interval from the Patala Formation (Kala Chitta Ranges), allows the recognition of the Larger Foraminiferal Turnover (LFT). The Larger Foraminiferal Turnover (LFT) observed in the Patala Formation is associated with the PETM (Paleocene Eocene Thermal Maximum) global climatic event and allows the recognition of the P/E boundary …

The Uses Of Expertise: Science, Medicine And Body/Self-Fashioning, Amanda J. Counts

Master's Theses

This paper draws on empirical evidence collected from pro-anorexia websites and qualitative interviews with dieters to develop an analysis of the uses of medical and scientific expertise in processes of body- and self-fashioning. It builds on previous work by examining how `lay publics' refashion expertise in order to use it for new purposes, sometimes contradictory to the purposes of medicine itself. Four distinct groups are analyzed: Women diagnosed with anorexia; women diagnosed with EDNOS (Eating Disorder Not Otherwise Specified); dieters using traditional methods of caloric restricting; and dieters using a new method called Primal Dieting. Overall, respondents indicated an ambivalence …

The Decentralization And Centralization Of Curriculum In The Primary Education Of Burkina Faso, Simon A. Ziba
