A Mixed Methods Analysis Of The Concept Of Female Sexual Health, Laura C. Ford

Dissertations

The theoretical concept of health includes the ability to function physiologically, perceive a state of wellness, participate in social relationships, and be disease-free. Currently, the medical field approaches sexuality from a disease prevention and treatment perspective. Female sexual health must be understood holistically (i.e., emotionally, sociologically, and physiologically) for healthcare providers to help their patients optimize their sexual health; however, little research has been conducted from a holistic perspective. This study's purpose was to begin an exploration of the meaning of female sexual health.

This study utilized focus groups and a survey to explore the concept female sexual health as …

The Role Of Communication Channel, Feedback Valence And Cultural Differences In Performance Appraisal Outcomes, James C. Matchen

Dissertations

The effects of feedback valence (positive or negative) across culture (Individualistic or Collectivistic) for both the verbal and nonverbal communication channels on performance appraisal outcomes were investigated. It was hypothesized that participants would react differently to the performance appraisal they received based on (1) their own cultural values and on (2) the valence of the verbal feedback and nonverbal feedback provided by the manager. Main effects of both verbal feedback valence and nonverbal feedback valence were predicted and found. Participants reported more positive reactions to both the performance appraisal process and to the manager after receiving positive feedback than after …

Wireless Lan 802.11x In U.S. Educational Institutions: Technology Adoption And Digital Divide Perspective, Sang-Baek (Chris) Kang

Dissertations

The current study of wireless local area networks (WLAN) adoption in educational institutions is motivated by three reasons. First, most students are exposed to information technology when they are at K-12 schools. Indeed, educational institutions represent the largest segment in the WLAN market in the United States in terms of the number of adopters. Second, WLAN requires a substantial financial investment before it can enable an "anytime, anywhere" learning environment, and may thereby aggravate the digital divide between rich and poor schools. Third, although WLAN is infrastructure technology, it has different characteristics compared to other infrastructure information technologies; traditional infrastructure …

Nurturing Peace: United Nations Peacebuilding Operations In The Aftermath Of Intrastate Conflicts, 1945-2002, Duk Hyang Kim

Dissertations

After World War II, intrastate conflicts rapidly replaced interstate conflicts as the dominant threat to international peace and security, a trend that has become all the more evident in the post-Cold War era. Given the prevalence of civil wars, there is increasing awareness of the need for post-conflict settlement procedures, development of local capacity for conflict resolution, and long-term peacebuilding efforts. In his 1992 An Agenda for Peace, former UN Secretary General Boutros Boutros-Ghali encouraged the international community to take responsibility for the full range of post-conflict management roles by introducing ?post-conflict peace-building.? Even though the term ?peacebuilding? did not …

Structural Models Of Comorbid Anxiety And Depression In A Primary-Care Older Adult Sample: Effect Of Medical Illness Severity, Threat, Chronicity, And Progressiveness On Model Fit, William Michael Palmer

Dissertations

Recent research suggests that anxiety disorders may be more common in later life than previously thought. Among other factors, the presence of comorbid mood disorders and medical illness confounds accurate assessment and diagnosis of these conditions in the elderly. There have been few studies, however, examining the structural relationships between anxiety and depression with older-adult samples, and even fewer have considered the effect of medical illness on these relationships. This study examined three established structural models of anxiety and depression, using a clinical sample of older adults seeking treatment in a primary-care setting (N = 2,163). It was hypothesized that …

Novel Model Of Cerebrospinal Fluid Dynamics Based On Hemodynamically Driven Cyclic Brain Compliance Variation, Bruno A. Mantilla

Dissertations

This study provides a novel explanation for the CerebrQ-Spinal Fluid (CSF) flow pattern observed in phase contrast cine-MRJ studies. CSF dynamics has been traditionally explained as a bulk flow from the site of production to the site of absorption. Studies done with phase contrast cine-MRI show a more complex CSF movement, that is not explainable by the bulk flow paradigm. This study describes a mechanism explaining how the energy delivered by the heart in each cycle is responsible not only for the blood flow, but also for the CSF circulation. This mechanism is based on a cyclic variation of brain …

Designing Multimodal Interaction For The Visually Impaired, Xiaoyu Chen

Dissertations

This research investigates sighted and visually impaired users' multimodal interaction choices when given an interaction grammar that supports speech and touch input modalities. It investigates whether task type, working memory load, or prevalence of errors in a given modality impact a user's choice. Theories in human memory and attention are used to explain the users' speech and touch input coordination.

Among the abundant findings from this research, the …

Design And Implementation Of Split Tcp In The Linux Kernel, Rahul Jain

Dissertations

The Transmission Control Protocol (TCP) was designed for reliable communication between computers over networks of unpredictable quality. It has admirably succeeded in satisfying the needs of the growing internet. Yet, there are combinations of network problems too bad even for TCP. In particular, in the situation of simultaneously very high delay (e.g. a satellite link) and high loss or even fading (a low quality earthlink or wireless link) on the same connection TCP can break down.

A known solution is “Split TCP” where one or more proxies (called Helper Boxes) are introduced to break the end-to-end connection into few (almost) …
