Factors That Influence Physicians To Assume Leadership Roles: A Focus On Clinical Integration, Jennifer Lynne Jackson

Dissertations

The Patient Protection and Affordable Care Act of 2010 (PPACA) drastically altered the healthcare industry in the United States. Along with multiple other directives, the PPACA mandated that physicians and hospitals work together in strategies known as clinical integration. For effective clinical integration to be achieved, interdependence among physicians and hospitals is required to provide the highest quality outcomes for patients at the best possible value. To this end, healthcare leaders have identified that the key to establishing successful clinical integration is the presence and commitment of physician leaders (Penlington & Marshall, 2016).

This study explores factors that influenced a …

Viewability Prediction For Display Advertising, Chong Wang

Dissertations

As a massive industry, display advertising delivers advertisers’ marketing messages to attract customers through graphic banners on webpages. Display advertising is also the most essential revenue source of online publishers. Currently, advertisers are charged by user response or ad serving. However, recent studies show that users barely click or convert display ads. Moreover, about half of the ads are actually never seen by users. In this case, advertisers cannot enhance their brand awareness and increase return on investment. Publishers also lose much revenue. Therefore, the ad pricing standards are shifting to a new model: ad impressions are paid if they …

Protein Engineering Of Cota Laccase By Using Bacillus Subtilis Spore Display, Silu Sheng

Dissertations

Spore display offers advantages over more commonly utilized microbe cell-surface display systems. For instance, protein-folding problems associated with the expressed recombinant polypeptide crossing membranes are avoided. Hence, a different region of protein space can be explored that previously was not accessible. In addition, spores tolerate many physical/chemical extremes. The aim is to improve pH stability using spore display. The maximum activity of CotA is between pH 4 and 5 for the substrate ABTS (ABTS = diammonium 2, 2’-azino-bis(3-ethylbenzothiazoline-6-sulfonate)). However, the activity dramatically decreases at pH 4. The activity is not significantly altered at pH 5. CotA is used as a …

Nurses' Perceptions Of The Image Of The Profession Of Nursing, Lorraine E. Emeghebo

Dissertations

The purpose of this study was to understand the evolution of nurses' perceived image of nursing from the time nurses begin their career and through various phases of nursing experience. The image of nursing as perceived by nurses and by the public affects recruitment of new nurses and retention of experienced nurses (Buerhaus, 2000, Irvine & Evans, 1995, Nevidjon & Erickson, 2001). There is a projected deficiency of 800,000 nurses by 2020 (National Center for Health Workforce Analysis, 2002) that has been attributed, in part, to low enrollments and graduations from nursing programs, as well as nurses leaving the profession. …

Healthcare Use Self-Efficacy In Adults Who Are Homeless, Jared Ian Israel

Dissertations

The physical and mental health care needs of homeless adults are extensive. However, these needs regularly go unmet. Healthcare use behavior is complex and involves a range of obstacles. As such, self-efficacy, an individual’s belief in his or her ability to perform a given behavior, appears to be a relevant factor in healthcare use. While current theory supports this notion and research has confirmed the role of self-efficacy in health behavior generally, a validated measure of healthcare use self-efficacy has not previously existed. The aim of this study was to develop and validate the Healthcare Use Self-Efficacy List (HUSEL) in …

A Study Of The Pokot Cultural Worldview: Missiological Implications For Seventh-Day Adventist Witness Among The Pastoral Nomads Of Kenya, Haron Matwetwe

Dissertations

Seventh-day Adventist witness among the nomadic peoples of the East Africa region is faced with a number of challenges. Although the Church enjoys relative success in reaching most communities, its growth and development appears restricted to locations occupied by the settled communities. Unfamiliarity with nomads’ cultural structures and values is partial explanation for why missionaries have failed to effectively connect with the nomads thereby hampering the establishment of a more vibrant mission work in pastoral nomadic regions.

This qualitative research sought to describe the Pokot cultural worldview as a step toward understanding their socio-cultural context and identify barriers to effective …
