The concept of social media has grown rapidly in the last years. This can be attributed to the rate of adoption and the penetration of social media around the world. Currently, there is an estimate of over two billion people that are actively using social media. The increased usage of social media has changed the way people interact and communicate. Literature suggests that Internet-enabled social networks (relationship between or among individuals and groups) are developing faster than offline relationships. Previous studies have linked social media to the social network theories that define social relationships based on the actors, the ties that exist and the flow of resources among them. This is made possible by social networking sites and other Internet enabled services that allow friends to meet, connect and interact. Social media allow for individuals, groups or organisations to build their social network of friends and followers. It also facilitates the formation of communities with common interest. Social media facilitate the creation and exchange of content such as text messages, images, audio and video formats among individuals or communities that share a common interest or belong to the same social network. Social capital theorists suggest that the ties that exist in social interaction like on social media have the ability to create benefit for the actors in the networks. This provides the foundation to study the benefits that individuals and organisations can obtain from social media. The opportunity to target and communicate directly with the target market and potential customer qualifies social media as a valuable marketing tool and an important component of the integrated marketing communication. As a marketing communication tool, social media introduces a completely new paradigm into marketing communications. Therefore marketing professionals and academics are continuously seeking how to take advantage of social media for different industries. In the field of politics, the use of marketing concepts to engage voters and drive collective participation in political processes has become critical due to stiff competition. The use of social media for political campaigning and engagement could be beneficial, but politicians and political organisations are not taking full advantage of the concept. Previous studies show that organisations are aware of the opportunities that social media could provide for their organisations. However, they are reluctant because they are faced with the problems of lack of information on how to implement social media for business purposes. This treatise investigates the approach and critical success factors for the use of social media for political campaigning and engagement. To evaluate the conceptual framework that was suggested by this study based on the literature review and case studies, an empirical study was conducted among the members of the Democratic Alliance in the Eastern Cape. A survey was conducted among the members of the Democratic Alliance in the Eastern Cape using a questionnaire and 92 responses were received. The questionnaire measured the respondents’ social media usage, level of political engagement, perception on the use of social media for political engagement and the level of political activities on social media. Also, hypotheses were tested to examine the assumption that there might be an association between the respondents’ gender, population group and level of political activities on social media. The findings of this study indicate that a structured approach, a strong emphasis of engaging followers socially and micro-targeting are critical to effective implementation of social media for political campaigning and engagement. Other factors include the direct involvement of leadership, listening and encouragement of user generated contents. This study concludes that political organisations can use social media to establish multi-levelled social networks that provide access to their target audience and also reach potential audience through their friends. This social connectedness can then be translated into political social capital for campaign and engagement purposes.

This study examined the professional networking of North and West Texas public school superintendents. It looked at how these superintendents professionally network, use professional organizations in networking, and how they extend opportunities beyond the organizations to gain knowledge and information about their demanding and stressful responsibilities. Lastly, it looked at superintendents in the field on whom others rely for knowledge and understanding. Surveys were mailed out to 443 North and West Texas public schools. Only the superintendents from those districts were asked to complete the survey. This limitation was desired to restrict the population to only the superintendents of schools, thus focusing the study on the professional networking of only superintendents. Three hundred sixty (360) superintendents responded to the survey, a return rate of 81.3%. This research concluded that superintendents professionally network by communicating through monthly meetings, organizational conferences or meetings, or email. Their networks are facilitated through communication, contacts, location, longevity, and organizational associations. These organizations provide the superintendent's primary network contact. The number of contacts in a network is usually a small group of 5 to 9 professionals who are known from longevity in the profession, prior educational positions, similar district size, being located in or near a city, and other geographic neighbors.

The fight against epidemics/pandemics is one of man versus nature. Technological advances have not only improved existing methods for monitoring and controlling disease outbreaks, but have also provided new means for investigation, such as through modeling and simulation. This dissertation explores the relationship between social structure and disease dynamics. Social structures are modeled as graphs, and outbreaks are simulated based on a well-recognized standard, the susceptible-infectious-removed (SIR) paradigm. Two independent, but related, studies are presented. The first involves measuring the severity of outbreaks as social network parameters are altered. The second study investigates the efficacy of various vaccination policies based on social structure. Three disease-related centrality measures are introduced, contact, transmission, and spread centrality, which are related to previously established centrality measures degree, betweenness, and closeness, respectively. The results of experiments presented in this dissertation indicate that reducing the neighborhood size along with outside-of-neighborhood contacts diminishes the severity of disease outbreaks. Vaccination strategies can effectively reduce these parameters. Additionally, vaccination policies that target individuals with high centrality are generally shown to be slightly more effective than a random vaccination policy. These results combined with past and future studies will assist public health officials in their effort to minimize the effects of inevitable disease epidemics/pandemics.

Thesis (M.Inf) --University of Limpopo, 2019. / The use of social media (SM) tools in both public and private institutions is growing remarkably. Academic libraries, in particular are confronted with serious challenges of becoming the leader in adopting various SM platforms to enhance the delivery of library and information services to their users. This study investigated the extent and ways in which librarians attached to the University of Limpopo library use SM platforms in the provision of library and information services to their patrons. The study examined types of SM tools used, purposes that SM tools are used for in academic libraries, factors that determine and impede the use of SM, as well as the attitudes of the library staff towards the use of SM in providing library and information services. The study adopted a qualitative research approach through the use of a semi-structured interview (administered face-to-face) with 10 academic librarians at the University of Limpopo (UL) as a data collection method. The findings of the study show that UL library staff largely use SM platforms such as Facebook to market and promote library services as well as Library-Blog to liaise with the schools or faculties. The study further revealed that librarians at UL are not in charge of SM applications. Instead the Marketing and Communication Department administrator is responsible for the management of SM in the university. The study notes that library personnel are aware of various SM platforms. Therefore, it has a direct influence on their use in work-related tasks. Moreover, the ease of use, low cost, high demand and usefulness of SM applications are contributory factors which motivated the librarians to want to use it. The study further reveals factors that inhibit the effective use of these applications and recommends that library management should create SM policies to boost the effective use of SM for the benefit of library patrons.

The aim of the study was to analyze the psychometric properties of the Adolescent- Risk of Addiction to Social Networks and Internet Scale (ERA-RSI) in Peruvian students. The sample was composed by 755 students (52.2% women), whose ages ranged from 13 to 24 years (M = 17, SD = 2.93) and attended private schools (62.2%) or universities (33.8%). The internal structure of the ERA-RSI, the invariance according to the level of instruction and sex, its relationship with other variables, and the reliability by internal consistency were analyzed. The results of the Confirmatory Factor Analysis (CFA) indicate a four-dimensional structure with adequate fit indices (χ2 / gl = 3.81, CFI = .91, TLI = .90, RMSEA = .061 [.058, .065], SRMR = .061) and which is invariant according to the level of instruction (school and university) and sex (men and women). In addition, good reliability is shown by internal consistency (ω = .74 to .83). For its part, convergent validity was performed with the Social Media Addiction Questionnaire (ARS) a positive, moderate to strong statistically significant correlation were found between the dimensions of both tests. In conclusion, the present adaptation of the ERA-RSI has, in general, adequate empirical evidence of validity and reliability and can be used in future research. / El objetivo fue analizar las evidencias de validez y confiabilidad de la Escala de Riesgo de Adicción-adolescente a las Redes Sociales e Internet (ERARSI) en estudiantes peruanos. Participaron 755 estudiantes (52.2% mujeres), con edades comprendidas entre los 13 a 24 años (M = 17, DE = 2.93) pertenecientes a escuelas (62.2%) o universidades privadas (33.8%). Se analizó la estructura interna de la ERA-RSI, la invarianza según nivel educativo y sexo, su relación con otras variables y la confiabilidad por consistencia interna. Los resultados del Análisis Factorial Confirmatorio (AFC) indican una estructura de cuatro dimensiones con adecuados índices de ajuste (χ2 / gl = 3.81, CFI = .91, TLI = .90, RMSEA = .061 [.058, .065], SRMR = .061) y que es invariante según el nivel educativo (escolares y universitarios) y el sexo (hombres y mujeres). Además, se evidencia una buena confiabilidad por consistencia interna (ω = .74 a .83). Por su parte, la validez convergente se realizó con el Cuestionario de Adicción a las Redes Sociales (ARS) y se encontró, entre las dimensiones de ambas pruebas, correlaciones positivas, estadísticamente significativas y de magnitud entre moderadas y fuertes. En conclusión, la presente adaptación de la ERA-RSI cuenta, en general, con adecuadas evidencias empíricas de validez y fiabilidad y puede ser usada en futuras investigaciones.

Autistic individuals experience marginalization and stigmatization, and are often not connected to mainstream services or organizations fostering peer relationships (Boundy, 2008; Jaarsma & Welin, 2012; Robertson, 2010). Therefore, the accomplishments of the online Autistic community in building a community for self-advocacy, peer-support, friendships, and identity development (Brownlow & O'Dell, 2006; Kidney, 2012) are important to recognize, empirically examine, and promote (Blume, 1997a; Davidson, 2008). Utilizing a community-based participatory research approach (CBPR; Israel, Schulz, Parker, & Becker, 1998) the Academic Autistic Spectrum Partnership in Research and Education (AASPIRE; www.aaspire.org) conducted the AASPIRE Internet Use, Community, and Well-Being Study, and collected data from 151 autistic adults and 173 non-autistic adults. The current study utilized data from the AASPIRE Internet Use, Community, and Well-Being Study on involvement in the online Autistic community, communication preferences, Autistic identity, and self-determination. The aims and rationale for the study were to contribute to the small body of quantitative literature on the online Autistic community, including expanding on findings that support positive outcomes of involvement in the online Autistic community (Kidney, 2012), and whether communication preference influences the relationships. The study also sought to examine the fit of an integrated model of associations among involvement in the online Autistic community, Autistic Identity, and self-determination in autistic adults who do and do not prefer online communication. Additionally, the study aimed to promote positive Autistic research and the voices of autistic participants and CBPR partners by challenging common misperceptions about autistic individuals and community/social interactions, understand the impact of communication preference, and inform policy and education designed for autistic individuals. The study used data to develop a multi-dimensional construct of involvement in the online community as well as explore the Autistic Identity Scale. The main findings included positive relationships between involvement in the online Autistic community and Autistic identity (r=.33, p<.01), as well as between involvement and self-determination (r=.38, p<.01) in autistic adults. Exploratory analyses yielded mixed results in the cross-sectional sample that was relatively limited in demographic diversity and small considering the number and type of analyses (n=324). Main findings include no moderating impact of preference to communicate online or population type (autistic or non-autistic) on the significant relationships between (1) involvement in the online community and self-determination or (2) involvement in the online community and Autistic identity. However, exploring the relationships among the variables with structural equation modeling, analyses indicated that no significant relationship exists between involvement in the online Autistic community and self-determination in autistic adults who do not prefer online communication. Findings indicate the need for further research on the complex impact of communication preference in larger samples of autistic adults. Despite sample limitations and mixed results from exploratory analyses, the findings mostly support the associations of involvement in the online Autistic community with Autistic identity and self-determination. The discussion addresses implications of the findings for theory, research, and action. For example, findings may influence how autistic individuals are provided education about and access to new media for fostering community, or lead to the development of online interventions or techniques for the promotion of positive outcomes in autistic individuals.

How we share our good news with people can have a significant effect on our lives. Sharing good news on social media sites involves a process called capitalization. Capitalization has been shown to increase well-being when others provide appropriate responses in face-to-face interactions. To see if this effect on well-being extends to our online presence, this study utilized the social media site Facebook to observe if capitalization predicted well-being and relationship satisfaction. This study used data collected from 137 participants recruited from an undergraduate participant pool and from Amazon Mechanical Turk. Consistent with hypotheses, participants who reported receiving active and constructive responses after sharing a positive event on Facebook also reported greater personal well-being and relationship satisfaction. Although future experimental research is needed to establish causality, the current results suggest that the ways in which friends respond to social media posts are associated with personal and relationship well-being. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

Thesis (MPhil) -- Stellenbosch University, 2012. / ENGLISH ABSTRACT: In a time of uncertainty for newspapers due in part to dwindling circulation, loss of advertising revenue and declining readership, Internet-based technologies have continued to grow. The unprecedented rise of social media, of which Facebook and Twitter are wellknown examples, has not gone unnoticed by the newspaper community. Despite their initial misgivings about the credibility of the information disseminated on these media, mainstream journalists worldwide have gradually started to adopt social media as professional tools. Social media serve as channels that help to funnel information towards journalists. Some newspaper journalists also use these media to broadcast news and promote their personal brands. The continued use of social media on a professional level will arguably have an impact on the daily routines and cultures within a newsroom. Academic research in this area is limited, especially within the South African context. This study explores whether the professional use of social media, with specific reference to Facebook and Twitter, influences the processes and cultures of news selection and presentation at the South Africa newspapers Rapport and the Mail & Guardian. A newsroom study within a social constructionism paradigm employed a combination of quantitative and qualitative research methodologies, including self-administered questionnaires, semi-structured interviews and ethnography. The main findings of this study were that the majority of journalists at Rapport and the Mail & Guardian used Facebook and Twitter actively on a professional level – mainly for trend tracking. The newsroom cultures were open and encouraging towards social media use. Journalists were also aware that social media create opportunities for their audiences to challenge the traditional roles of journalists and the realities constructed by the mainstream media. According to the journalists from Rapport and the Mail & Guardian the professional use of social media had not significantly altered their processes of news selection and presentation. / AFRIKAANSE OPSOMMING: Terwyl koerante ’n onsekere tyd beleef, deels weens dalende sirkulasiesyfers, ’n verlies aan advertensie-inkomste en ’n afname in lesertalle, het Internetgebaseerde tegnologieë aanhou groei. Die ongekende groei van sosial media, waarvan Facebook en Twitter welbekende voorbeelde is, het nie ongesiens by die koerantgemeenskap verby gegaan nie. Ondanks hul aanvanklike bedenkinge oor die geloofwaardigheid van inligting wat op dié media versprei word, het hoofstroomjoernaliste wêreldwyd geleidelik begin om sosiale media as professionele hulpmiddels te aanvaar. Sosial media dien as kanale waardeur inligting na joernaliste vloei. Sommige koerantjoernaliste gebruik ook die media om nuus uit te saai en hul persoonlike handelsmerk te bemark. Die volgehoue gebruik van sosial media op ’n professionele vlak sal bes moontlik ’n impak op die daaglikse roetine en kulture binne ’n nuuskantoor hê. Akademiese navorsing op die gebied is beperk, veral binne die Suid-Afrikaanse konteks. Hierdie navorsing ondersoek of die professionele gebruik van sosiale media, met spesifieke verwysing na Facebook en Twitter, ’n invloed het op die prosesse en kulture van nuusseleksie en -aanbieding by die Suid-Afrikaanse koerante Rapport en die Mail & Guardian. ’n Nuuskantoorstudie, binne ’n sosiale konstruktivisme paradigma, het ’n kombinasie van kwantitatiewe en kwalitatiewe navorsingsmetodologieë ingespan, insluitende: selfgeadministreerde vraelyste, halfgestruktureerde onderhoude en etnografie. Die hoofbevindinge van die studie was dat die meerderheid van die joernaliste by Rapport en die Mail & Guardian Facebook en Twitter aktief op ’n professionele vlak gebruik het – hoofsaaklik om tendense dop te hou. Die nuuskantoorkulture was oop en aanmoedigend teenoor die gebruik van sosiale media. Joernaliste was ook bewus daarvan dat sosiale media geleenthede skep vir hul gehore om die tradisionele rol van joernaliste, sowel as die realiteite wat deur die hoofstroommedia geskep word, te betwis. Volgens die joernaliste van Rapport en die Mail & Guardian het die professionele gebruik van sosiale media nie hul nuusinsamelings- en aanbiedingsprosesse noemenswaardig beïnvloed nie.
