Participation Of Students In Their Own Transition/Education Planning Process: Perceptions Of Key Persons., Billie L. Friedland Jan 1998

Participation Of Students In Their Own Transition/Education Planning Process: Perceptions Of Key Persons., Billie L. Friedland

Graduate Theses, Dissertations, and Problem Reports (ETD)

The literature indicates that a lack of participation in their own decision-making process has contributed to a diminished quality of life for people with disabilities (Sands, Kozleski, & Goodwin, 1991; Sands & Doll, 1996). Classroom and living situations often foster learned dependence, resulting in over-reliance on others to find problem solutions. To improve students' influence over their transition outcomes, educators and community persons need to provide students with appropriate instruction and opportunities to participate fully in their own life planning. This exploratory, comparative study utilized individual interviews, focus groups, and Individual Transition-Education Plan (ITEP) document reviews to explore and compare …

The goals of this exploratory study were to identify the issues associated with the inclusion or exclusion of recording in the social work curriculum and describe teaching strategies and materials used by instructors who include content on recording. The four research questions addressed: whether social work faculty perceive recording as legitimate curriculum content; the factors associated with deciding to include or exclude recording; the content of any instruction on recording; and teaching …


The Relations Among Daily Minor Stressors, Solicitous Spousal Responding, And Illness Behavior In Type Ii Diabetes Mellitus., James Curtis Findley Jan 1998

The Relations Among Daily Minor Stressors, Solicitous Spousal Responding, And Illness Behavior In Type Ii Diabetes Mellitus., James Curtis Findley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although persons with Diabetes Mellitus (DM) report more physical symptoms than do relatively healthy persons, the relation between blood glucose (BG) and symptom reporting in persons with DM has been shown to be idiosyncratic. Even in subjects that demonstrate and significant BG/symptom relation, the effect is not stable over time (i.e., greater than eight months). Daily minor stressors and solicitous spousal responding have been shown to be related to symptom reporting in other chronic illness populations and might account for variance in symptom reporting by persons with DM. Thirty-three participants with Type II DM monitored BG, physical activity, and stress …

Investigative Interviewing With Children: Evaluation Of The Effectiveness Of A Training Program For Child Protective Service Workers., Kurt Andrew Freeman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Conducting investigative interviews with children who were allegedly sexually abused is perhaps one of the most challenging aspects of child protective service (CPS) workers' jobs. Previous research suggests that training workshops on investigative interviewing conducted with front-line workers, such as police officers and CPS workers, may result in improved knowledge about appropriate strategies to use. However, limited research has addressed whether such trainings result in improvements in actual interviewing skills. The present investigation assessed the impact of a six-hour training workshop on CPS workers' knowledge about and performance during investigative interviews. Results suggest that the training impacted participants' knowledge on …

A Study Of The Impact Of Mentoring On West Virginia Public School Teachers., Linda K. Dunlap

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the wave of educational reform that swept the United States during the decade of the eighties, many became concerned about the apparent large number of beginning teachers who were leaving the profession in the first three years. Those who worked closely with teacher education programs, began to look at how teachers were trained. Out of their research and dialogue came the need to foster better ways to help new teachers make the transition from student to classroom teacher. Teacher induction programs which included formal mentoring programs were initiated very quickly across many states, since it was believed that a …


States And War Coalitions: A Case Study Of The Gulf War., George Sprowls Jan 1998

States And War Coalitions: A Case Study Of The Gulf War., George Sprowls

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation discusses the theoretical and empirical differences between war coalitions and alliances. It also provides some answers to the question: "Why do some nations choose to join war coalitions while other nations, in apparently similar circumstances, choose not to join?" At the systemic level of analysis, dependence on economic aid, membership in a formal alliance with a key participant, and proximity to the conflict are correlated with the level of participation in a war coalition. At the state level, the degree of democratization, levels of regime fragmentation and vulnerability, and the presence of statutory prohibitions against using military force …

Foundations Of Object-Based Specification Design, David March Fleming Dec 1997

Foundations Of Object-Based Specification Design, David March Fleming

Graduate Theses, Dissertations, and Problem Reports (ETD)

To enhance applicability and encourage its use, a component or a component-based system must have a well-designed set of interface features as well as a proper explanation of these features. The dual problem of designing a suitable set of interface features in addition to properly explaining its behavior is termed the specification design problem. This dissertation identifies observability, controllability, and a performance-motivated pragmatic criterion as essential properties of desirable formal specifications for reusable object-based software components. The pragmatic criterion guides the design of component interfaces and component libraries to a suitable set of features so that they are widely applicable, …

Vincennes: From French Colonial Village To American Frontier Town, 1730-1820., Denise Marie Wilson

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation explores the social, political, and economic transitions which occurred among the French-Canadian inhabitants of Vincennes (in present-day southern Indiana) as the colonial French village became an American frontier town. Few studies in recent decades have explored the colonial history of the Middle West, and even fewer make the chronological transition from the Colonial Period to the Early National Period. This study investigates the changes experienced by the French when they became British subjects (in 1763) and American citizens (in 1783). It also contributes to a fuller understanding of midwestern history by showing how the normal process of pioneer …

A Signal Detection Analysis Of Body Image Distortion Among Women With Bulimia Nervosa., Lynda Anne Szymanski

Graduate Theses, Dissertations, and Problem Reports (ETD)

The clinical conceptualization of body-image distortion among persons with eating disorders typically emphasizes sensory disturbances and de-emphasizes nonsensory, environmental variables. The present study examined body-size misperceptions using a signal detection paradigm in 20 women with bulimia and 20 women without present symptomology or history of an eating disorder. First, subjects estimated their body sizes using a video distortion camera. Second, each subject judged how similar or dissimilar each of 192 distorted and undistorted images was to her actual body size using a 5-point rating scale. The second phase of the study was repeated with one-half of the subjects given instructions …

Isolation And Characterization Of The 22 Kd Subunit Of Gluconate Dehydrogenase Derived From Pseudomonas Aeruginosa Pao1., John David Gordon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Approximately 95-99% of soil phosphorous is unavailable to plants, with {dollar}\\sim{dollar}90% of phosphate fertilizers also being rendered unavailable upon application. 2-Ketogluconate (2KG) has been shown to solubilize insoluble phosphates in vitro. If plants themselves could solubilize the insoluble phosphate in the soil, this would greatly reduce the need for phosphate fertilizers. Two greenhouse experiments were conducted to examine in vitro and in situ solubilization of insoluble phosphates (calcium phosphate, RP, and iron phosphate, IP) with increasing concentrations of 2KG, as seen through plant (Lycopersicon esculentum) growth and Pi uptake. In the first experiment (in situ solubilization), water alone showed a …


Male Adolescent Sex Offenders: The Relationship Between Early Victimization And Subsequent Offense Patterns., Mark Steven Metz Jan 1997

Male Adolescent Sex Offenders: The Relationship Between Early Victimization And Subsequent Offense Patterns., Mark Steven Metz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Twenty-three (23) incarcerated male adolescent sex offenders participated in structured interviews about their experiences as both victims and perpetrators of sexual assault. Data were analyzed for indications that some perpetrators use their offenses to reenact their victimization experiences in an effort to achieve mastery over their own sexual traumata. Data were also evaluated for evidence of differential victimization histories by molesters and rapists. Significant relationships were found between victimization and offense experiences, including the selection by offenders of victims who were the same race as the perpetrators against them, the recurrence in offenses of two types of sexual activity--simulated intercourse …
