<p> This thesis sought to narrow some of the knowledge gaps in political communication and advertising. By examining the content of local newspapers about U.S. Senate candidates, this research determined female candidates receive just as much, if not more, newspaper coverage than male candidates. There were few endorsements given to candidates, especially from national and state office holders. Additionally, this thesis found that many of the newspaper articles were focused on non-issues. Previous studies on women in politics suggested female candidates often face more media hurdles than their male counterparts, specifically receiving less print media coverage. In contrast, this thesis found that women may no longer face the same barriers as they once did.</p>

<p>This sequential, mixed methods research addressed emerging social media use practices among IT professionals and explored lived experiences of senior IT leaders relative to successful organizational social media adoption and use. The study was informed by structuration theory and elements from the universal technology adoption and use (UTAUT) model, generation theory, and open leadership theory. In the first, quantitative descriptive research phase, an online survey was administered to describe IT professionals' uses of and attitudes toward social media in the workplace. Survey results based on 406 responses from IT professionals in the greater Seattle area indicated widespread use of different social media applications, and also showed that Millennial IT professionals use social media more extensively and are have more positive opinions about social media as compared to their older colleagues. Survey findings also indicated that an increasing number of employers are developing formal social media strategies and adopting policies and guidelines governing the use of social media in the workplace. The second, qualitative hermeneutic phenomenological research phase built on survey results and involved interviews with 13 senior IT leaders in the greater Seattle area. Findings indicated that despite the inherent user-driven nature of social media, senior leadership plays a key role in driving strategic social media adoption and in ensuring broad participation across generational cohorts and employee groups. Findings from the qualitative research phase further suggested that social media can help employees and stakeholders communicate and collaborate more effectively and efficiently, and that leaders can derive significant benefits from social media without compromising the integrity of their organizations. </p>

<p> Extrinsic motivation may affect knowledge sharing in a virtual community. As virtual communities have become ubiquitous, understanding knowledge sharing in virtual communities has become very important. Knowledge sharing is one of the factors that allow virtual communities to be viable. This study sought to observe knowledge sharing in a virtual community, which does not use extrinsic motivation techniques as incentives to share knowledge. This correlation study used a framework that included the elements of social capital and outcome expectations. This study found that extrinsic rewards over time appear not to be important in knowledge sharing. The long term effect may be that extrinsic rewards are much less important than the design of the virtual community and the internal motivation of the members of the virtual community. One-hundred and thirty-three persons participated in this study.</p>

<p> This paper examines national Internet control from a policy regime perspective. The mechanisms through which governments attempt to control the Internet may be developed and implemented by different institutions and agencies, or fall outside of a formal regulatory structure entirely. As such, the totality of the institutions and practices of national Internet control is better conceptualized not as a regulatory regime, but as a control regime. After a survey of the critical policy and control dimensions, a six-part typology of control regimes is proposed. The purpose of this study and typology is exploratory. With comparative research about Internet control regimes at a relatively early stage, this paper aims to enable the formation of concepts and hypotheses about the interrelationship, or co-presence, of key distinguishing variables in different Internet control regimes.</p>
