Sustainable Mountain Tourism Development Illustrated In The Case Of Switzerland, Benedikt Schorner

SPNHA Review

The concept of sustainable mountain tourism development meets the needs of the present tourists and host regions while protecting and enhancing opportunities for future generations (WTO, 2001). The principles of sustainable tourism development are composed of environmental, economic, and socio-cultural aspects. In order to be successful in the long-term, an equilibrium among these three dimensions must be established (Samy & El-Barmelgy, 2005). The Swiss Federal Council established a general framework for its Sustainable Development Strategy 2000, which is used in this paper to show successful policymaking in this area. Furthermore, policy priorities, recommendations, challenges, and successful strategies for sustainable mountain …

State Level Efficiency Measures For Healthcare Systems, Kamil Makiela

SPNHA Review

This article presents a parametric approach to healthcare system productivity analysis across the USA between 2000 and 2003. Though similar productivity analyses have been made on a country level, little research is devoted to state-level healthcare efficiency analysis. Hence, the aim of this exercise is to compute the so-called technical frontier also known as the best practice frontier which represents maximum obtainable output given inputs. The difference between each state’s health level and its potentially attainable maximum denotes a given state healthcare inefficiency. The Stochastic Frontier approach used in this article allows the computation of efficiency scores as well as …

Effects Of A Computerized Professional Development Program On Teacher And Student Outcomes, Joseph B. Fisher, Jean B. Schumaker, John Culbertson, Donald D. Deshler

Peer Reviewed Articles

Effects of a computerized professional development (PD) program for a concept teaching routine were investigated in two studies. For each, teachers were randomly assigned to either a virtual workshop group that used a multimedia software program for PD or an actual workshop group that participated in a live PD session. In Study 1, the teachers’ knowledge about the routine and planning for the routine significantly improved after completing either workshop; no significant differences were found between the groups. Both teacher groups were satisfied with the PD. In Study 2, the teachers’ performance of the routine in their classrooms improved, as …

Cohabiting, Family And Community Stressors, Selection, And Juvenile Delinquency, Christopher A. Kierkus, Brian R. Johnson, John D. Hewitt

Peer Reviewed Publications

Prior research has established that children from traditional, two-parent nuclear families experience a lower risk of delinquency than children raised in alternative family structures. However, many studies have ignored the effect of parental cohabiting on delinquent development. A growing body of research suggests that cohabiting (even among biological parents) may be harmful to children. This study tests the hypothesis that cohabiting is associated with four different types of delinquent behavior. It examines two theoretical models, a family stress model and a community stress/selection model, as possible explanations of ‘‘the cohabiting effect.’’ The analysis reveals that cohabiting is generally associated with …

Price And Pretense In The Baby Market, Kimberly D. Krawiec

Faculty Scholarship

Throughout the world, baby selling is formally prohibited. And throughout the world babies are bought and sold each day. As demonstrated in this Essay, the legal baby trade is a global market in which prospective parents pay, scores of intermediaries profit, and the demand for children is clearly differentiated by age, race, special needs, and other consumer preferences, with prices ranging from zero to over one hundred thousand dollars. Yet legal regimes and policymakers around the world pretend that the baby market does not exist, most notably through prohibitions against “baby selling” – typically defined as a prohibition against the …

From Judge To Dean: Reflections On The Bench And The Academy, David F. Levi

Faculty Scholarship

In July of 2007, having served nearly seventeen years as a United States District Judge with chambers in Sacramento, California, I moved to Durham, North Carolina, to become the fourteenth dean of the Duke University Law School. I would concede that in the grand scheme of things such a transition must be deemed unremarkable. Lawyers have become soldiers, presidents, artists, and inn keepers. Judges have left the bench to do much the same. Nonetheless, in the somewhat closed worlds of the federal bench and the legal academy, at a time when the two worlds have seemed to drift apart, such …

Human Rights And Intellectual Property: Mapping The Global Interface, Laurence R. Helfer, Graeme W. Austin

Faculty Scholarship

Human Rights and Intellectual Property: Mapping the Global Interface explores the intersections between intellectual property and human rights law and policy. The relationship between these two fields has captured the attention of governments, policymakers, and activist communities in a diverse array of international and domestic political and judicial venues. These actors often raise human rights arguments as counterweights to the expansion of intellectual property in areas including freedom of expression, public health, education, privacy, agriculture, and the rights of indigenous peoples. At the same time, the creators and owners of intellectual property are asserting a human rights justification for the …

Development Of Novel Backscatter Communication Systems Using A Multi-Hop Framework And Distributed Beamforming, Vikram Reddy Surendra

Masters Theses

"The goal of this thesis it to develop a wireless networking framework for battery-free devices based on passive, backscatter communication. In contrast to traditional, active communication systems, where the radio signal has to be generated using large amount of energy from batteries, the passive systems reflect the RF signal. The information is encoded by modulating the reflected signal, which consumes significantly less energy than active transmission. The existing passive, backscatter systems have limited communication capabilities. For example, the Radio Frequency Identification (RFID) systems support short-distance, direct communication between active reader and passive tags. The communication range is limited due to …

Semantic Processing In Adults With High Functioning Autism, Katherine Deragon

Electronic Theses and Dissertations

This study examined the semantic processing of 19 adults with high-functioning autism (HFA) and 18 age and verbal-IQ matched controls using language tasks that varied in the demand for simple or integrative processing. On standardized measures, the individuals with autism had relatively intact vocabulary skills compared to controls, whereas the comprehension and use of figurative language was relatively weaker. The adults with HFA were relatively insensitive to context and incorrectly completed sentences with a commonly associated word pair rather than a semantically appropriate response. On a 3-letter word stem completion task, the autism group provided a similar mean number of …

Reducing Defaults In Microfinance: A Case Study Of Fundación Integral Campesino (Finca) Costa Rica, Katherine Stackel

Electronic Theses and Dissertations

This study seeks to determine why some microfinance institutions have high default rates, while others have low ones. Three literature-based hypotheses regarding default reduction were tested on communal credit enterprises (CCEs) of a poverty-focused microfinance program called FINCA Costa Rica. Specifically, five CCEs in the Osa region, and one CCE (not within the Osa) created by FINCA CR. Four financially healthy CCEs that have low default rates were compared with the one that is at a high-risk for failure, to determine what exactly caused this to happen when so many variables were controlled. It is hypothesized that more group unity, …

Multivariate Outlier Mining Using Cluster Analysis: Case Study - National Health Interview Survey, Md Monir Hossain Sharker

Electronic Theses and Dissertations

Outlier mining is a fundamental issue in many statistical analyses, especially in multivariate cases. Outliers may exert undue influence on outcomes of the analysis. In most cases, it is a big challenge to reveal the pattern of the outliers and the "outlyingness". There are several approaches and methods to detect anomalous data points in data. But no single method is perfect for every data set especially when the data dimension and volume is high. In this thesis, I review distance-based clustering methods for multivariate outlier mining and demonstrate the usefulness of it in a medical setting. Specifically, I discuss Hierarchical …

Average peak torque (T), peak torque/body weight (T:BW), average power (P), and rate of torque development (RTD) were assessed. Electromyographic data were obtained from elbow extensors and flexors. A repeated measures ANOVA with post hoc analysis demonstrated that T, T:BW, P, and RTD were higher in the baseline, compared to the post ACC …

The Acute Time Course Of Concurrent Activation Potentiation, Luke Garceau, Erich Petushek, Mckenzie Fauth, William Ebben

Exercise Science Faculty Research and Publications

This study evaluated the acute time course of the ergogenic effect of concurrent activation potentiation (CAP). Forty-two men and women, including CAP non-responders and responders, performed a 5 second isometric knee extension on a dynamometer with the use of remote voluntary contractions (RVC). Mean torque was assessed in seven 500 millisecond (ms) time periods. A two-way repeated measures ANOVA revealed significant main effects for time period (p ≤ 0.001), but no significant interaction between time period and CAP non-responders and responders (p > 0.05). The ergogenic effects of CAP are accrued during the first 1000ms. Concurrent activation potentiation responders produce greater …

Paddy And The Public: Irish Immigrants, New York City, And Mass Culture, 1830-1860, William Patrick Mcgovern

Electronic Theses and Dissertations

This thesis investigates the role of visual images in reflecting and shaping attitudes of the native-born towards Irish immigrants in antebellum New York City. Representations in mass culture, specifically in the popular press and on minstrel sheet music covers, serve as a window into understanding native-born discourses on Irish Americans. Various elements of the Irish immigrant trope are analyzed, including massive immigration, crowding, disease, poverty, drunkenness, violence, public women, labor competition, and political corruption. In addition to visual analysis, gender, environmental, and discourse analysis are applied to representations of Irish immigrants. Taking the study of antebellum nativism in a new …

An Exploration Of Counselling Practices With Women Survivors Of Childhood Sexual Abuse: Should Therapists Ask About Thoughts Or Behaviour Involving Sex With Children?, Angela Karen Hovey

Theses and Dissertations (Comprehensive)

Helping professionals and women, themselves, have been reluctant to recognize or acknowledge that females can and do sexually abuse children and adolescents. Research has also demonstrated that females most at risk to abuse children are those who were themselves victims of severe child sexual abuse (CSA) The purpose of this research was to explore whether or not current counselling practices with women survivors of CSA reflect the belief that women do not sexually abuse children. This study also focuses on whether or not therapists create space for discussion about thoughts and behaviour involving sexual abuse of children and adolescents with …

Place And Food: A Relational Analysis Of Personal Food Environments, Meanings Of Place And Diet Quality, Ellen Desjardins

Theses and Dissertations (Comprehensive)

This study investigates the relational layers of meanings that people experience at places in their food environment, and how individuals express a sense of place through their collective interactions with, and understandings of, food places. It also explores the patterns of difference among these meanings of place and sense of place in terms of their potential association with dietary quality. The context of this inquiry was two-fold: first, the need identified by several population health researchers and to re-imagine place as relational and include it in the study of behavioural responses to the changing food environment; and secondly, my interest …

Jane Austen In Contemporary Film: Interpretations And Reflections Of Austen's Novels In Contemporary Culture, Lindsay Anderson

Senior Honors Theses and Projects

There is no escaping Jane Austen. Though it has been nearly two hundred years since her death, Austen and her work continues to capture the minds and hearts of readers worldwide. Our fascination with her novels continues to grow, finding new expression in literature, television and film each year. What makes this phenomenon so interesting is the reality that Austen’s novels are so firmly “dated” – that is, so rigorously cemented and relevant to the age in which it was written. Why do readers and viewers continue to find Austen’s works so relevant, given that it is so bound to …

Intercultural Competence For The Nutrition Professional, Cynthia S. Klement

Senior Honors Theses and Projects

Diversity training for nutrition care professionals is essential in order to provide patients with culture-specific strategies that allow them to succeed with their health program. Nutritionists are faced with the challenge of understanding the dietary preferences of their cross-cultural patients, as well as appreciating a patient's religious beliefs regarding dietary selections by identify foods that will or won't support a prescribed nutritional program. Knowledge of intercultural nonverbal and verbal behaviors is becoming increasingly necessary, as is who ultimately makes medical decisions for the patient.
