Producing Early Modern Space And The Mind In Public And Closet Drama, Megan M. Gallagher

Dissertations and Theses @ UNI

The construction of space has become such a common process for modernity that its culture would argue spatial experiences as intrinsic in nature. However, it is through the consideration of the experience of space and spatial boundaries one notices the cooperative nature of space. This thesis explores the early modem constructions of space and the development of the modem idea of the mind through the closet dramas of John Milton (Samson Agonistes) and Elizabeth Cary (The Tragedy of Mariam the Fair Queen of the Jewry), and the public dramas of William Shakespeare (Measure for Measure and Julius Caesar). Our notions …

Disordered Eating Habits And Extreme Weight Loss Techniques In Collegiate Wrestlers: A Qualitative Analysis, Jaime Marie Mayer

Dissertations and Theses @ UNI

Wrestlers have often been targeted as high-risk athletes for developing eating disorders. Research has found that wrestlers do practice extreme weight loss and disordered eating behaviors that are consistent with eating disorders. However, little evidence suggests that wrestlers also possess the psychological aspect that is required in order for a person to be diagnosed with an eating disorder according to the DSM (2000).

Many times researchers conclude that few wrestlers meet the criteria for eating disorders, but they participate in many behaviors that put them at risk of developing an eating disorder in the future. Very few if any researchers …

Data indicated that although empirical research states …

Asking School Psychologists How Job Satisfaction Can Be Increased, Justin S. Janssen

Dissertations and Theses @ UNI

School psychology faces retention issues due to a current and projected shortage of school psychologists and the large number of baby boomers getting ready to retire. Meeting this need becomes vital in order to prevent negative effects of the shortage from continuing. Research has supported a link between job satisfaction and retention in the school psychology research as well as in job satisfaction research in general. Much of the current literature on the job satisfaction of school psychologists, however, focuses only on the identification of correlates with job satisfaction and largely avoids asking practitioners how their job satisfaction can be …

Being In The World : An Existential Inquiry Of Knowing One's Self Through A Personal Project : In The Context Of Dissertation Survival, Tomoe Kitajima

Dissertations and Theses @ UNI

This study--a philosophical exploration, partly in an autoethnographical account--provides an empirical demonstration that one's personal project has a strong and positive impact on the dissertation process both for endurance to complete the process and for quality of the product. The concept of project is often explained as one's pursuit of his or her most important philosophical issues. This dissertation originated in the very beginning of my doctoral education in summer 2000 when I first encountered the man behind the coffee shop counter. In his life story he expressed a strong question about the problem of knowledge and authentic living. How …

The Role Of Animal-Assisted Therapy In Initial Psychotherapy Sessions With Adolescents, Erin B. Stromberg

Dissertations and Theses @ UNI

Animal-assisted therapy (AAT) is defined as "a goal directed intervention in which an animal, meeting specific criteria, is an integral part of the treatment process" (Nebbe, 1995, p. 40). Since its first introduction into the scientific community in the 1960s, AAT has grown in both recognition and application. This is primarily attributable to the characteristics of AAT that allow it to be appropriate for a wide range of populations. These qualities are shown to be especially effective in research with children (Menzies Inc., 2003). Interventions that exercise the advantageous qualities of AAT, and its service in promoting the well being …

Development Of An Ankle Function Model, Kelli R. Snyder

Dissertations and Theses @ UNI

Lateral ankle sprains (LAS) represent the most common orthopedic injury treated by athletic trainers, yet there is no consensus regarding the measurement of the effectiveness of care (e.g. outcomes). Further compounding this problem is the repetitive nature of LAS, often referred to as "functional" or "chronic" ankle instability (FAI, CAI, respectively). Although a common entity in practice and research, FAI is inconsistently defined and assessed. Essentially, athletic trainers are neglecting to address one of the most important issues identified in their profession (outcomes) for the most common injury for which they provide care (LAS). Therefore, the purpose of this research …
