The Effect of Social Media on Public Awareness and Extra-Judicial Effects: The Gay Marriage Cases and Litigating for New Rights

Peterson, Sarahfina Aubrey 17 October 2014 (has links)
When the Supreme Court grants new rights, public awareness is a crucial part of enforcement. Gerald N. Rosenberg and Michael J. Klarman famously criticized minority rights organizations for attempting to gain new rights through the judiciary. The crux of their argument relied heavily on the American media's scanty coverage of Court issues and subsequent low public awareness of Court cases. Using the 2013 United States v. Windsor and Hollingsworth v. Perry rulings as a case study, I suggest that the media environment has changed so much since Rosenberg and Klarman were writing that their theories warrant reconsideration. Minority rights groups now have access to social media, a potentially powerful tool with which to educate the public about the Supreme Court and new rights granted by the Court.

Grief Lives Online: An Empirical Study of Kübler-Ross' Categories of Bereavement on MySpace Profiles

Malenkovich, Ilona Yurivna 04 October 2013 (has links)
With the widespread use of the Internet, grief has been extended in its representation. Specifically, social networking sites, like MySpace, have turned grief presentation from private expressions into public displays of mourning. This study utilizes the theoretical foundations of the grief presentation process of Kübler-Ross' (1969) five categories of bereavement (denial, anger, bargaining, depression and acceptance) to determine whether the grief presentation process is present in an online setting. In this study, the researcher conducted an empirical investigation of 4,931 comments, resulting in 22,263 bereavement themes outlined by Kübler-Ross, which were condensed into 2,288 time-point comparisons posted to 140 MySpace profiles of users who have passed-on. Results revealed noteworthy practices surrounding grief presentation on the MySpace profiles of the deceased. Specifically, bereaved commenters post a significantly greater number of bereavement narratives in the first three months post-mortem as opposed to months four through six. Additionally, race and sex of the deceased, as well as sex of the bereaved, did not prove to be mitigating factors in online grief presentation. Moreover, across observed races and sexes, the bereavement category of acceptance was found most often, followed by depression, denial, anger, and bargaining. Findings suggest that post-mortem commenting behavior blends current memorializing practices while also extending the space for communication and grief presentation. Additional implications for understanding grief communication on MySpace and future directions for research conclude this study.

Involvement in the Online Autistic Community, Identity, Community, and Well-Being

Kidney, Colleen Anne 01 January 2012 (has links)
The values of the disability rights movement and community psychology promote research that focuses on improving the lives of individuals with disabilities (Dowrick & Keys, 2001). Using the Internet for social interactions has been shown to contribute to an individual's identity development, sense of community, and well-being (Obst, Zinkiewicz, & Smith, 2002a; Turkle, 1995). While challenges in typical social interactions have traditionally been considered a defining feature of autism spectrum disorder, autistic individuals have taken advantage of the Internet to develop social interactions (Blume, 1997a). The present study focused on the online Autistic community and how the importance and value of involvement in it is related to Autistic identity, sense of community, and psychological well-being. The Academic Autistic Spectrum Partnership in Research and Education (AASPIRE) partnered with the Gernsbacher Lab to form the Gateway Project. Using the Gateway Project, AASPIRE conducted the Internet Use, Community, and Well-Being Study and collected data from 72 autistic adults online. It was hypothesized that the importance and value of involvement in the online Autistic community would be positively related to Autistic identity and sense of community, Autistic identity and sense of community would be positively related, and Autistic identity and sense of community would be positively related to psychological well-being. It was also hypothesized that the positive relationship between the importance and value of involvement in the online Autistic community and psychological well-being would be mediated by Autistic identity and sense of community. Correlations were examined among the hypothesized relationships, and a mediated regression model (Baron & Kenny, 1986) was used to explore the relationship between the importance and value of involvement in the online Autistic community and psychological well-being with Autistic identity and sense of community as mediators. Significant relationships were found between the importance and value of involvement in the online Autistic community and Autistic identity, between the importance and value of involvement in the online Autistic community and sense of community, and between autistic identity and sense of community. As a first step to test the mediated regression models, psychological well-being was regressed on the importance and value of involvement in the online Autistic community. The regression was not significant; therefore the hypothesized model was not significant. Despite non-significant mediated regression model results, significant relationships among the importance and value of involvement in the online Autistic community and Autistic identity and sense of community offer important results. These finding illuminate the potential positive impact of the importance and value of involvement in the online Autistic community, including evidence counter to the myth that autistic individuals lack skills necessary for social relationships. These findings support the positive utility of involvement in the online Autistic community for autistic adults. Further research with a larger sample size is recommended, due to low power coefficients in the analyses. Additional research may also further illuminate the findings of the current study. Possible topics may include sense of community and Autistic identity in individuals that do not use the Internet, differences in the way the Internet is used in autistic individuals, and different measures of involvement in the online Autistic community and well-being.

Trust management of social network in health care

Chomphoosang, Pawat 12 November 2013 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / The reliability of information in health social network sites (HSNS) is an imperative concern since false information can cause tremendous damage to health consumers. In this thesis, we introduce a trust framework which captures both human trust level and its uncertainty, and also present advantages of using the trust framework to intensify the dependability of HSNS, namely filtering information, increasing the efficiency of pharmacy marketing, and modeling how to monitor reliability of health information. Several experiments which were conducted on real health social networks validate the applicability of the trust framework in the real scenarios.

The effect of shared dynamic understanding on willingness to contribute information: design and analysis of a mega-collaborative interface

Newlon, Christine Mae 06 May 2016 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Collaborative helping via social networking conversation threads can pose serious challenges in emergency situations. Interfaces that support complex group interaction and sense-making can help. This research applies human-computer interaction (HCI), computer-supported cooperative work (CSCW), and collaboration engineering in developing an interactive design, the Mega-Collaboration Tool (MCT). The goal is to reduce the cognitive load of a group’s growing mental model, thus increasing the general public’s ability to organize spontaneous collaborative helping. The specific aims of this research include understanding the dynamics of mental model negotiation and determining whether MCT can assist the group’s sense-making ability without increasing net cognitive load. The proposed HCI theory is that interfaces supporting collaborative cognition motivate contribution and reduce information bias, thus increasing the information shared. These research questions are addressed: 1. Does MCT support better collaborative cognition? 2. Does increasing the size of the shared data repository increase the amount of information shared? 3. Does this happen because group members experience 1) a greater sense of strategic commitment to the knowledge structure, 2) increased intrinsic motivation to contribute, and 3) reduced resistance to sharing information? These questions were affirmed to varying degrees, giving insight into the collaborative process. Greater content did not motive group members directly; instead, half of their motivation came from awareness of their contribution’s relevance. Greater content and organization improved this awareness, and also encouraged sharing through increased enthusiasm and reduced bias. Increased commitment was a result of this process, rather than a cause. Also, MCT increased collaborative cognition but was significantly hampered by Internet performance. This challenge indicates MCT’s system components should be redesigned to allow asynchronous interaction. These results should contribute to the development of MCT, other collaboration engineering applications, and HCI and information science theory.

Political engagement and social networking sites exploring the relationship between social networking sites and political engagement in young adults

Toney, Jeffrey A. 01 January 2009 (has links)
Social Networking Sites (SNS) have extremely high rates of young adult users. Facebook.com report.s that more than half of its users are of college age. Due to the increasing number of political figures and political information on SNS, this study analyzes the relationship between SNS and political engagement. Specifically, this study seeks to determine if adults' consumption of political information on SNS leads to higher levels of political engagement. Political engagement is broken down into three different variables: political knowledge, political interest, and political participation. This study draws its data from a sample of 355 undergraduate college students. Data was collected through a volunteer self-administered survey questionnaire. Three sections respectively measured political engagement, social networking site dependency for political information, and demographic information. Data were collected from a junior college and a private university in Northern California. This study found a positive relationship between SNS dependency for political information and political interest and participation. In other words, individuals who depend on SNS for political information have higher levels of political interest and participation. There was no significant relationship found between political knowledge and SNS dependency. These results suggest that SNS may help foster political engagement in young adults.

A study of Myspace and Facebook from the perspectives of uses and gratification and impression management

Urista, Mark A. 01 January 2008 (has links)
This thesis explored MySpace and Facebook, two popular social networking sites (SNS), from the perspectives of the uses and gratification model and impression management theory. As a qualitative exploratory study, this thesis had three objectives. First, it investigated why young people use SNS. Second, it sought to discover how members use SNS for self-presentation. Finally, it aimed to contribute to the current body of literature and serve as a basis for future qualitative and quantitative studies on SNS. The focus groups that were conducted for this thesis elicited ten themes that provided insights on the motivations and behaviors of individuals who use SNS for needs fulfillment and impression management. These themes included: 1) efficient communication, 2) convenient communication, 3) curiosity of others, 4) popularity, 5) relationship formation and reinforcement, 6) self-enhancement, 7) otherenhancement, 8) self-disclosure, 9) conformity and 1 0) identity-management. Based on the first five themes, the study suggested that an emerging theory of instant gratification is being developed. The theory helps researchers explain why young people use SNS and predict what factors motivate young people to get ,_ involved heavily in SNS. Based on the second five themes, this study confirmed the relevance of Goffi:nan's theories of the presentation of the self in explaining how young people manage their impressions through SNS. As a powerful socialization agent, SNS provide new opportunities and diverse ways of presenting one's self online. Though there are some evident differences between online and face-to-face social interaction, it is clear that Goffman's theories will continue to help researchers explain self-presentation within the context of SNS.

Virtual group movie recommendation system using social network information

Manamolela, Lefats'e 27 November 2019 (has links)
M. Tech. (Department of Information and Communication Technology, Faculty of Applied and Computer Sciences), Vaal University of Technology. / Since their emergence in the 1990’s, recommendation systems have transformed the intelligence of both the web and humans. A pool of research papers has been published in various domains of recommendation systems. These include content based, collaborative and hybrid filtering recommendation systems. Recommendation systems suggest items to users and their principal purpose is to increase sales and recommend items that are predicted to be suitable for users. They achieve this through making calculations based on data that is available on the system. In this study, we give evidence that the research on group recommendation systems must look more carefully at the dynamics of group decision-making in order to produce technologies that will be more beneficial for groups based on the individual interests of group members while also striving to maximise satisfaction. The matrix factorization algorithm of collaborative filtering was used to make predictions and three movie recommendation for each and every individual user. The three recommendations were of three highest predicted movies above the pre-set threshold which was three. Thereafter, four virtual groups of varied sizes were formed based on four highest predicted movies of the users in the dataset. Plurality voting strategy was used to achieve this. A publicly available dataset based on Group Recommender Systems Enhanced by Social Elements, constructed by Lara Quijano from the Group of Artificial Intelligence Applications (GIGA), was used for experiments. The developed recommendation system was able to successfully make individual movie recommendations, generate virtual groups, and recommend movies to these respective groups. The system was evaluated for accuracy in making predictions and it was able to achieve 0.7027 MAE and 0.8996 RMSE. This study was able to recommend to virtual groups to enable social network group members to engage in discussions of recommended items. The study encourages members in engaging in similar activities in their respective physical locations and then discuss on social network.

The use of social networking services to enhance the learning experience and academic performance of tertiary level learners

Da Rocha, R. D. 01 1900 (has links)
M. Tech. (Department of Information and Communication Technology, Faculty of Applied and Computer Sciences). Vaal University of Technology. / There are many learning paradigms in the academic field, many of which have been used since the advent of universities and other learning institutions. However, the advent and subsequent popularisation of the Internet in the early 1990's has led to the development of new learning paradigms. Simultaneously, students currently enrolled at higher education institutions (HEI) fall under the Generation Z cohort, otherwise known as Millennials. This generation has grown up with widespread usage of the internet, and research has shown that engagement with these students in an educational setting has slowed down. This study endeavoured to establish whether the use of Social Networking Services (SNSs) could aid to better engage student in the teaching and learning process, and if so, whether there would be a measurable improvement in the marks of students enrolled in a final year Information Technology (IT) module at a HEI. Facebook and YouTube were the SNSs chosen as the focus of the study. Data collection was achieved by means of mixed-methods methodology. Semi-structured interviews were held with lecturers to determine their perceptions regarding the use of Facebook from an educational perspective. thematic analysis was performed to identify prominent themes in the qualitative data. Statistical analysis was performed on the result of two groups of students that took the final year module over two semesters. An action research based case study was designed as intervention for students in the 2nd semester involving the use of SNSs. The marks of the two groups were compared and contrasted to determine whether an improvement in results had taken place. Students participating in the action research case study also completed a survey for the purpose of gauging their experiences in the use of SNSs for the action research interventions are also highlighted and discussed, and thematic analysis is performed. After analysis of the gathered data had taken place, it was clear that the majority of participants in the study found that SNSs could add value to the teaching and learning process and there was a small to moderate improvement in results. Guidelines for other institutions that would like to integrate SNSs into their teaching and learning processes are proposed and a model has been developed.
