Faculty Perceptions Of The Role Of Foreign Language Education At West Virginia University, William L. White May 2007

Faculty Perceptions Of The Role Of Foreign Language Education At West Virginia University, William L. White

Graduate Theses, Dissertations, and Problem Reports (ETD)

Foreign language education has a long history within higher education. However, since the late 1960s, foreign language enrollment, measured by percentages of students taking language courses, has declined by almost 50% in American colleges and universities. The author contends that much of this decline can be explained by three concomitant forces; including (1) the rise of professional programs that are constrained by an exactness of education that precludes study beyond rather narrowly defined plans of study; (2) the lack of language learning success that foreign language students demonstrate upon completion of language programs; and (3) the failure of language departments …

Smoking As A Maladaptive Method Of Weight Control In Female College Students: Perceived Negative Health Effects And Weight Control Properties., Melissa M. Garrison

Graduate Theses, Dissertations, and Problem Reports (ETD)

Women are at great risks for smoking-related health consequences. Lung cancer is the leading cause of cancer deaths among women in the United States. A relationship exists between smoking behavior and weight control in women. Women are more likely to smoke to control their weight and experience higher relapse and dropout rates in smoking cessation programs due to issues of weight concern. The most effective smoking cessation programs are those that contain a cognitive behavioral component that addresses issues of weight concern in conjunction with the standard smoking cessation treatment. However, women are still experiencing high relapse and dropout rates …

Perceptions Of The Environment For Physical Activity: Perspectives From Community Residents And Policy Officials., John R. Geer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Adult residents (n = 184) of two counties in West Virginia completed a survey assessing perceptions of their physical and social environments, and self-reported physical activity (PA). Semi-structured interviews were conducted with nine of these participants who met CDC PA recommendations, and with 10 individuals involved in public policy regarding perceptions of their communities for PA and issues related to PA barriers. Active residents were more likely to use community facilities than inactive residents (p < .001). In addition, active residents reported significantly higher self-efficacy for meeting PA recommendations than inactive residents (p < .001). Overall, participants with high self-efficacy were eight times more likely to meet recommended levels of PA. Residents’ environmental barriers to PA included lack of accessibility to facilities, lack of community walkability, and safety and traffic issues. Personal barriers to PA were also commonly cited by residents, including being too busy/having competing demands and poor attitude/motivation. Residents cited the use of exercise partners or groups as being important for increasing physical activity. Policy officials cited similar environmental and personal barriers, but often placed responsibility for overcoming those barriers on the residents within their communities.
