This study examines factors associated with the frequency with which users of location-based social networks (LBSNs) "check-in" with their "friends." In addition to a variety of control factors (i.e., sex homophily, race homophily, geographic proximity, length of friendship, and "friendship" type, including non-romantic friend, romantic partner, and family), the central factors of interest were users' background and attitude homophily with, and relational closeness to, their "friends." Results demonstrate that relational closeness and "friendship" type (i.e., romantic partner) were significantly, positively associated with "check-in" frequency.

Facebook is among the top used websites in the world, and research has shown that Facebook use is related to individual personality characteristics such as well-being and self-esteem. This study builds on previous research, expanding to investigate attachment-related anxiety and avoidance and relational certainty. The current study examined relationships between Facebook use (both general and for surveillance) and relational certainty, attachment-related anxiety and avoidance, and self-esteem in undergraduate students (N = 261). Online methods were used for data collection, and individuals with their relationship displayed on Facebook reported more relational certainty; however, the more time they spent on the site, the less certain they were with their relationship. Individuals with high attachment-related anxiety were more likely to use Facebook for surveillance, and both attachment anxiety and Facebook use for surveillance were linked to lower self-esteem. These findings indicate that individuals with their relationship status displayed on Facebook have more relational certainty and exhibit less attachment-related anxiety and avoidance. Individuals with high attachment anxiety use Facebook for surveillance. These results add to the expanding literature on Facebook and social networking sites, showing that different people use Facebook in varying ways. As social networking continues to be a staple in the lives of nearly one billion users, it is important to keep researching how people use it and what the potential implications of this use are.

Thesis (M. A. (Media Studies)) -- University of Limpopo, 2022 / Social networking became a common international trend which has spreads and reached almost every corner of the world. The use of social media platform has developed and exploded into an online platform where individuals can generate content, share it, bookmark it and network at an enormous rate. Amongst the users of social media, students and youth are the main users of social media sites. The research explored Facebook as a tool for improving marketing services at University of Limpopo. Institution of higher learning utilise Facebook for various reasons such getting more followers, maintain existing relationship between the university and its audience and also to communicate with the university audience. Social media can have a great impact on the university and its audience depending on the usage as a two-way communication platform. The main objectives of the study are to identify the manner in which institutions of higher learning use Facebook for marking purposes; examine the performance of Facebook for marketing; and establish the challenges and opportunities of using Facebook as a marking tool. The study employed Nick Couldry’s practice theory and Marketing communication mix theory which are highlighting the relationship between the media, people and organisations. The study also analysed other literature that supports the aim and objectives of the study. A qualitative method was used in the study and results obtained through the use of online observation and semi-structured interview. Content and thematic analysis was applied to analyse the data collected. The population used as a sample were marketing and communication department employees at the University of Limpopo who are working with the university social media pages. With online observation of the University of Limpopo’s Facebook page the findings show that the university’s social media portray specifically Facebook as a one-way communication which they convey messages on the platform without taking into consideration the comments, criticism and queries of the students or audience at large. The empirical findings of the study indicate that Facebook is the most used social media platform at the University of Limpopo. Moreover, participants have highlighted that the purpose of all social media platforms are used to market the institution and as platforms to convey messages to their followers, staff members and university community. v The findings expose the various opportunities and challenges in using social media. However, it is proved that the opportunities outweigh the threats. Some institutions of higher learning use more than one social media platform. However, Facebook was proven to be the most widely used social media followed by YouTube, Twitter and Instagram.

The increase in online social network (OSN) usage has led to personal details known as attributes being readily displayed in OSN profiles. This can lead to the profile owners being vulnerable to privacy and social engineering attacks which include identity theft, stalking and re identification by linking. Due to a need to address privacy in OSNs, this thesis presents a framework to quantify the vulnerability of a user¿s OSN profile. Vulnerability is defined as the likelihood that the personal details displayed on an OSN profile will spread due to the actions of the profile owner and their friends in regards to information disclosure. The vulnerability measure consists of three components. The individual vulnerability is calculated by allocating weights to profile attribute values disclosed and neighbourhood features which may contribute towards the personal vulnerability of the profile user. The relative vulnerability is the collective vulnerability of the profiles¿ friends. The absolute vulnerability is the overall profile vulnerability which considers the individual and relative vulnerabilities. The first part of the framework details a data retrieval approach to extract MySpace profile data to test the vulnerability algorithm using real cases. The profile structure presented significant extraction problems because of the dynamic nature of the OSN. Issues of the usability of a standard dataset including ethical concerns are discussed. Application of the vulnerability measure on extracted data emphasised how so called ¿private profiles¿ are not immune to vulnerability issues. This is because some profile details can still be displayed on private profiles. The second part of the framework presents the normalisation of the measure, in the context of a formal approach which includes the development of axioms and validation of the measure but with a larger dataset of profiles. The axioms highlight that changes in the presented list of profile attributes, and the attributes¿ weights in making the profile vulnerable, affect the individual vulnerability of a profile. iii Validation of the measure showed that vulnerability involving OSN profiles does occur and this provides a good basis for other researchers to build on the measure further. The novelty of this vulnerability measure is that it takes into account not just the attributes presented on each individual profile but features of the profiles¿ neighbourhood.

Tesis por compendio / [EN] Nowadays, online social networks (OSNs) have become a mainstream cultural phenomenon for millions of Internet users. Social networks are an ideal environment for generating all kinds of social benefits for users. Users share experiences, keep in touch with their family, friends and acquaintances, and earn economic benefits from the power of their influence (which is translated into new job opportunities). However, the use of social networks and the action of sharing information imply the loss of the users’ privacy. Recently, a great interest in protecting the privacy of users has emerged. This situation has been due to documented cases of regrets in users’ actions, company scandals produced by misuse of personal information, and the biases introduced by privacy mechanisms. Social network providers have included improvements in their systems to reduce users’ privacy risks; for example, restricting privacy policies by default, adding new privacy settings, and designing quick and easy shortcuts to configure user privacy settings. In the privacy researcher area, new advances are proposed to improve privacy mechanisms, most of them focused on automation, fine-grained systems, and the usage of features extracted from the user’s profile information and interactions to recommend the best privacy policy for the user. Despite these advances, many studies have shown that users’ concern for privacy does not match the decisions they ultimately make in social networks. This misalignment in the users’ behavior might be due to the complexity of the privacy concept itself. This drawback causes users to disregard privacy risks, or perceive them as temporarily distant. Another cause of users’ behavior misalignment might be due to the complexity of the privacy decision-making process. This is because users should consider all possible scenarios and the factors involved (e.g., the number of friends, the relationship type, the context of the information, etc.) to make an appropriate privacy decision. The main contributions of this thesis are the development of metrics to assess privacy risks, and the proposal of explainable privacy mechanisms (using the developed metrics) to assist and raise awareness among users during the privacy decision process. Based on the definition of the concept of privacy, the dimensions of information scope and information sensitivity have been considered in this thesis to assess privacy risks. For explainable privacy mechanisms, soft paternalism techniques and gamification elements that make use of the proposed metrics have been designed. These mechanisms have been integrated into the social network PESEDIA and evaluated in experiments with real users. PESEDIA is a social network developed in the framework of the Master’s thesis of the Ph.D. student [15], this thesis, and the national projects “Privacy in Social Educational Environments during Childhood and Adolescence” (TIN2014-55206- R) and “Intelligent Agents for Privacy Advice in Social Networks” (TIN2017-89156-R). The findings confirm the validity of the proposed metrics for computing the users’ scope and the sensitivity of social network publications. For the scope metric, the results also showed the possibility of estimating it through local and social centrality metrics for scenarios with limited information access. For the sensitivity metric, the results also remarked the users’ misalignment for some information types and the consensus for a majority of them. The usage of these metrics as part of messages about potential consequences of privacy policy choices and information sharing actions to users showed positive effects on users’ behavior regarding privacy. Furthermore, the findings of exploring the users’ trade-off between costs and benefits during disclosure actions of personal information showed significant relationships with the usual social circles (family members, friends, coworkers, and unknown users) and their properties. This allowed designing better privacy mechanisms that appropriately restrict access to information and reduce regrets. Finally, gamification elements applied to social networks and users’ privacy showed a positive effect on the users’ behavior towards privacy and safe practices in social networks. / [ES] En la actualidad, las redes sociales se han convertido en un fenómeno cultural dominante para millones de usuarios de Internet. Las redes sociales son un entorno ideal para la generación de todo tipo de beneficios sociales para los usuarios. Los usuarios comparten experiencias, mantienen el contacto con sus familiares, amigos y conocidos, y obtienen beneficios económicos gracias al poder de su influencia (lo que se traduce en nuevas oportunidades de trabajo). Sin embargo, el uso de las redes sociales y la acción de compartir información implica la perdida de la privacidad de los usuarios. Recientemente ha emergido un gran interés en proteger la privacidad de los usuarios. Esta situación se ha debido a los casos de arrepentimientos documentados en las acciones de los usuarios, escándalos empresariales producidos por usos indebidos de la información personal, y a los sesgos que introducen los mecanismos de privacidad. Los proveedores de redes sociales han incluido mejoras en sus sistemas para reducir los riesgos en privacidad de los usuarios; por ejemplo, restringiendo las políticas de privacidad por defecto, añadiendo nuevos elementos de configuración de la privacidad, y diseñando accesos fáciles y directos para configurar la privacidad de los usuarios. En el campo de la investigación de la privacidad, nuevos avances se proponen para mejorar los mecanismos de privacidad la mayoría centrados en la automatización, selección de grano fino, y uso de características extraídas de la información y sus interacciones para recomendar la mejor política de privacidad para el usuario. A pesar de estos avances, muchos estudios han demostrado que la preocupación de los usuarios por la privacidad no se corresponde con las decisiones que finalmente toman en las redes sociales. Este desajuste en el comportamiento de los usuarios podría deberse a la complejidad del propio concepto de privacidad. Este inconveniente hace que los usuarios ignoren los riesgos de privacidad, o los perciban como temporalmente distantes. Otra causa del desajuste en el comportamiento de los usuarios podría deberse a la complejidad del proceso de toma de decisiones sobre la privacidad. Esto se debe a que los usuarios deben considerar todos los escenarios posibles y los factores involucrados (por ejemplo, el número de amigos, el tipo de relación, el contexto de la información, etc.) para tomar una decisión apropiada sobre la privacidad. Las principales contribuciones de esta tesis son el desarrollo de métricas para evaluar los riesgos de privacidad, y la propuesta de mecanismos de privacidad explicables (haciendo uso de las métricas desarrolladas) para asistir y concienciar a los usuarios durante el proceso de decisión sobre la privacidad. Atendiendo a la definición del concepto de la privacidad, las dimensiones del alcance de la información y la sensibilidad de la información se han considerado en esta tesis para evaluar los riesgos de privacidad. En cuanto a los mecanismos de privacidad explicables, se han diseñado utilizando técnicas de paternalismo blando y elementos de gamificación que hacen uso de las métricas propuestas. Estos mecanismos se han integrado en la red social PESEDIA y evaluado en experimentos con usuarios reales. PESEDIA es una red social desarrollada en el marco de la tesina de Master del doctorando [15], esta tesis y los proyectos nacionales “Privacidad en Entornos Sociales Educativos durante la Infancia y la Adolescencia” (TIN2014-55206-R) y “Agentes inteligentes para asesorar en privacidad en redes sociales” (TIN2017-89156-R). Los resultados confirman la validez de las métricas propuestas para calcular el alcance de los usuarios y la sensibilidad de las publicaciones de las redes sociales. En cuanto a la métrica del alcance, los resultados también mostraron la posibilidad de estimarla mediante métricas de centralidad local y social para escenarios con acceso limitado a la información. En cuanto a la métrica de sensibilidad, los resultados también pusieron de manifiesto la falta de concordancia de los usuarios en el caso de algunos tipos de información y el consenso en el caso de la mayoría de ellos. El uso de estas métricas como parte de los mensajes sobre las posibles consecuencias de las opciones de política de privacidad y las acciones de intercambio de información a los usuarios mostró efectos positivos en el comportamiento de los usuarios con respecto a la privacidad. Además, los resultados de la exploración de la compensación de los usuarios entre los costos y los beneficios durante las acciones de divulgación de información personal mostraron relaciones significativas con los círculos sociales habituales (familiares, amigos, compañeros de trabajo y usuarios desconocidos) y sus propiedades. Esto permitió diseñar mejores mecanismos de privacidad que restringen adecuadamente el acceso a la información y reducen los arrepentimientos. Por último, los elementos de gamificación aplicados a las redes sociales y a la privacidad de los usuarios mostraron un efecto positivo en el comportamiento de los usuarios hacia la privacidad y las prácticas seguras en las redes sociales. / [CA] En l’actualitat, les xarxes socials s’han convertit en un fenomen cultural dominant per a milions d’usuaris d’Internet. Les xarxes socials són un entorn ideal per a la generació de tota mena de beneficis socials per als usuaris. Els usuaris comparteixen experiències, mantenen el contacte amb els seus familiars, amics i coneguts, i obtenen beneficis econòmics gràcies al poder de la seva influència (el que es tradueix en noves oportunitats de treball). No obstant això, l’ús de les xarxes socials i l’acció de compartir informació implica la perduda de la privacitat dels usuaris. Recentment ha emergit un gran interès per protegir la privacitat dels usuaris. Aquesta situació s’ha degut als casos de penediments documentats en les accions dels usuaris, escàndols empresarials produïts per usos indeguts de la informació personal, i als caires que introdueixen els mecanismes de privacitat. Els proveïdors de xarxes socials han inclòs millores en els seus sistemes per a reduir els riscos en privacitat dels usuaris; per exemple, restringint les polítiques de privacitat per defecte, afegint nous elements de configuració de la privacitat, i dissenyant accessos fàcils i directes per a configurar la privacitat dels usuaris. En el camp de la recerca de la privacitat, nous avanços es proposen per a millorar els mecanismes de privacitat la majoria centrats en l’automatització, selecció de gra fi, i ús de característiques extretes de la informació i les seues interaccions per a recomanar la millor política de privacitat per a l’usuari. Malgrat aquests avanços, molts estudis han demostrat que la preocupació dels usuaris per la privacitat no es correspon amb les decisions que finalment prenen en les xarxes socials. Aquesta desalineació en el comportament dels usuaris podria deure’s a la complexitat del propi concepte de privacitat. Aquest inconvenient fa que els usuaris ignorin els riscos de privacitat, o els percebin com temporalment distants. Una altra causa de la desalineació en el comportament dels usuaris podria deure’s a la complexitat del procés de presa de decisions sobre la privacitat. Això es deu al fet que els usuaris han de considerar tots els escenaris possibles i els factors involucrats (per exemple, el nombre d’amics, el tipus de relació, el context de la informació, etc.) per a prendre una decisió apropiada sobre la privacitat. Les principals contribucions d’aquesta tesi són el desenvolupament de mètriques per a avaluar els riscos de privacitat, i la proposta de mecanismes de privacitat explicables (fent ús de les mètriques desenvolupades) per a assistir i conscienciar als usuaris durant el procés de decisió sobre la privacitat. Atesa la definició del concepte de la privacitat, les dimensions de l’abast de la informació i la sensibilitat de la informació s’han considerat en aquesta tesi per a avaluar els riscos de privacitat. Respecte als mecanismes de privacitat explicables, aquests s’han dissenyat utilitzant tècniques de paternalisme bla i elements de gamificació que fan ús de les mètriques propostes. Aquests mecanismes s’han integrat en la xarxa social PESEDIA i avaluat en experiments amb usuaris reals. PESEDIA és una xarxa social desenvolupada en el marc de la tesina de Màster del doctorant [15], aquesta tesi i els projectes nacionals “Privacitat en Entorns Socials Educatius durant la Infància i l’Adolescència” (TIN2014-55206-R) i “Agents Intel·ligents per a assessorar en Privacitat en xarxes socials” (TIN2017-89156-R). Els resultats confirmen la validesa de les mètriques propostes per a calcular l’abast de les accions dels usuaris i la sensibilitat de les publicacions de les xarxes socials. Respecte a la mètrica de l’abast, els resultats també van mostrar la possibilitat d’estimarla mitjançant mètriques de centralitat local i social per a escenaris amb accés limitat a la informació. Respecte a la mètrica de sensibilitat, els resultats també van posar de manifest la falta de concordança dels usuaris en el cas d’alguns tipus d’informació i el consens en el cas de la majoria d’ells. L’ús d’aquestes mètriques com a part dels missatges sobre les possibles conseqüències de les opcions de política de privacitat i les accions d’intercanvi d’informació als usuaris va mostrar efectes positius en el comportament dels usuaris respecte a la privacitat. A més, els resultats de l’exploració de la compensació dels usuaris entre els costos i els beneficis durant les accions de divulgació d’informació personal van mostrar relacions significatives amb els cercles socials habituals (familiars, amics, companys de treball i usuaris desconeguts) i les seves propietats. Això ha permés dissenyar millors mecanismes de privacitat que restringeixen adequadament l’accés a la informació i redueixen els penediments. Finalment, els elements de gamificació aplicats a les xarxes socials i a la privacitat dels usuaris van mostrar un efecte positiu en el comportament dels usuaris cap a la privacitat i les pràctiques segures en les xarxes socials. / Alemany Bordera, J.

This thesis examines the political public relations campaign of the Democratic Alliance in the 2009 elections in order to explain the party’s performance in these elections. The research is premised on John Petrocik’s (1996) issue ownership theory. A number of quantitative and qualitative content analyses were conducted to provide answers to the main research questions. These involved: the party’s 286 media releases; party leader Helen Zille’s 2009 campaign speeches; and Zille’s Facebook platform. Results revealed that although the DA demonstrated extreme political resilience amidst fierce challenges in the 2009 elections, the party primarily campaigned on an anti-ANC ticket and a fair amount of negative advertising against the governing party to win itself votes. Not only did the party fail to “associate” itself with real issues affecting South African voters—especially the poor Black African majority which constitutes the largest voting bloc—it failed to pronounce itself clearly on other issues. Instead, the party attached itself to a multitude of shared issues, often “trespassing” on issues of common concern not necessarily “owned” by any one political party. This study also deduced that while Facebook facilitated public opinion on the DA in the 2009 elections, it still could not be regarded as a genuine public sphere in the South African context. / Communication Science / M.A. (Communication)

Thesis (MPhil (Political Science))--University of Stellenbosch, 2010. / In the 17th and 18th centuries the bourgeois public sphere emerged as the conceptual space between the public, with its enclosed institutions and organisations, and the circle of the private life. It is within this more or less autonomous space that public discourse took place and public opinion, as a function of public discourse, was produced. The public sphere was realised as a necessary precondition of deliberative democracy where it needed to manifest commitments to freedom and equality in the communicative interaction between those partaking in the deliberative process. Since the 17th and 18th centuries, the public sphere has undergone various transformations and, even though it is largely argued that the utopian public sphere as conceptualised by Habermas does not yet exists, it is regarded as a necessary precondition that all democracies should strive towards. Since the 19th century, media has been one of the main intermediary institutions of the public sphere. Initially, the earlier mass media of press and broadcasting were regarded as adequate and beneficial for the conduct of democratic politics and the facilitation of public opinion in the public sphere. Information flow was, however, vertical and the heightened commercialisation experienced within the media market lead to the neglect of democratic communication roles between the public itself and the leaders, institutions and organisations. These forms of mass communication thus limited access and discouraged active political participation and deliberative dialogue within the public sphere. In the 20th and 21st centuries, new media, especially the internet, have been hailed as a potential way to break away from the vertical information flow and to create new arenas for public discourse. One emerging contending form of new media is social networking sites (SNSs). Even though SNSs were not initially developed for political reasons, they have been utilised by political figures in an attempt to broaden voter reach and to enhance their campaigns. Amongst the SNSs available on the internet, Facebook has emerged as the largest, fastest growing and most popular SNS amongst internet users between the ages of 18 and 24 in the world. In the past, this age demographic has shown a disinterest in politics and has thus been recognised as the previously politically disengaged age demographic. American president Barack Obama realised the potential of Facebook and incorporated it in his new ii media campaign during the presidential election of 2008. Facebook enabled Obama to expand his voter reach and communicate with the previously politically unengaged age demographic. It also enabled him to create an arena where political information regarding the candidate, campaign and relevant political issues can be provided. This opened a communication flow between Facebook members and the president. Arenas for public discourse were also established and the potential of Facebook to facilitate public opinion was realised. In this study, the question is asked whether Facebook, as a SNS, can be seen as an adequate forum where public discourse takes place and public opinion, as the function of public discourse, is facilitated. This study will therefore aim to explore whether a Facebook, as SNS, can be seen as a public sphere. With the help of a case study of the 2008 Obama campaign, Facebook has shown the potential to allow for public discourse to take place. Thus the notion of Facebook as facilitator of public opinion is supported by this study. / Die burgerlike openbare sfeer, as die konseptuele area tussen die publiek, met sy ingeslote instellings en organisasies, en die private lewe, het sy ontstaan vanuit die 17de en 18de eeu. Dit is binne hierdie min of meer outonome area waar openbare diskoers plaasvind en waar openbare mening, as ʼn funksie van die openbare diskoers, geproduseer word. Die openbare sfeer is ʼn noodwendige voorvereiste van ʼn beraadslagende demokrasie waar dit nodig is om verbintenisse tot vryheid en gelykheid in die kommunikasie interaksie tussen die wat aan die beraadslagingsproses deelneem, te manifesteer. Die openbare sfeer het verkeie omvormings ondergaan en, al word daar geargumenteer dat die utopiese openbare sfeer soos deur Habermas gekonseptualiseer nog nie bereik is nie, word dit as ʼn noodsaaklike vereiste waarna enige demokrasie moet streef, gesien. Sedert die 19de eeu word media as een van die hoof intermediêre instellings van die openbare sfeer beskou. Die drukpers en uitsaaipers was aanvanklik voldoende en voordelig vir die bedryf van demokratiese politiek en die fasilitering van openbare mening in die openbare sfeer. Die vloei van inligting was egter vertikaal en die verhoogde kommersialisering van die mediamarkte het tot die afskeep van demokratiese kommunikasierolle tussen die publiek self en die leiers, instellings en organisasies gelei. Hierdie vorms van massakommunikasie het dus toegang tot, en die aktiewe deelname in die politieke en beraadslagende dialoog binne die openbare sfeer beperk en ontmoedig. Gedurende die 20ste en 21ste eeue is nuwe media, veral die internet, as ʼn potensiële manier om van die eenrigting kommunikasievloei weg te breek en nuwe arenas vir openbare diskoers te skep, erken. Sosiale Netwerkingswebtuistes (SNWs) is een van die opkomende kompeterende vorms van nuwe media. Selfs al was SNWs aanvanklik nie vir politieke doeleindes ontwikkel nie, was dit wel deur die politieke figure, in ʼn poging om kiesersomvang te verbreed en om hul veldtogte uit te brei, gebruik. Onder die SNWs wat op die internet beskikbaar is, het Facebook as die grootste, vinnigste groeiende en gewildste onder die internetgebruikers tussen die ouderdom van 18 en 24 jaar in die wêreld ontstaan. In die verelede het hierdie jaargroep belangeloos teenoor politiek opgetree en was hulle sodoende as die voorheen polities onbetrokke jaargroep erken. Die Amerikaanse president, Barack Obama, het die iv potensiaal van Facebook besef en dit in sy nuwe-media veldtog gedurende die 2008 verkiesing ingesluit. Facebook het Obama in staat gestel om se kiesersomvang te verbreed en om veral met die voorheen polities onbetrokke jaargroep te kommunikeer. Dit het hom ook in staat gestel om ʼn arena te skep waar politieke inligting oor die kandidaat, veldtog en ter saaklike inligting aan Facebook-lede beskikbaar gestel is. Dit het ʼn vloei van kommunikasie tussen Facebook-lede en die president geskep. Arenas waar openbare diskoers kon plaasvind, is ook skep en die potensiaal van Facebook om openbare mening te fasiliteer, is besef. In hierdie studie word die vraag gestel of Facebook, as ‘n SNW, as ‘n genoegsame forum waar openbare diskoers plaasvind en openbare mening as ‘n funksie van openbare diskoers gefasiliteer word, dien. Hierdie studie poog derhalwe om ondersoek in te stel of Facebook, as SNW, as ‘n openbare sfeer erken kan word. Met behulp van die gevallestudie aangaande die 2008 Obama veldtog, blyk dit dat Facebook die potensiaal het om openbare diskoers te fasiliteer. Die idee dat Facebook ʼn fasiliteerder van openbare mening is, word derhalwe deur hierdie studie ondersteun.

The introduction of Social Media (SM) into sports communications in professional leagues is disrupting the traditional methods of sports media relations. In the past, teams used websites to post information for fans, but it was strictly a one-way format of communication whereby a story was posted for fans to read. To fully engage with this new communication channel, the sports communications departments in professional leagues have begun to use SM to communicate directly with fans through platforms like Twitter and Facebook. Currently, SM like Twitter allows the team communication departments to communicate directly with fans in an interactive two-way format that is not mediated by a reporter or someone from a traditional media outlet. In addition, the open format of SM means that media relations staff are no longer the only intermediary between the media and the players; through the use of SM like Twitter, a professional athlete can now communicate directly to fans without gatekeepers like the media or the sports communications department of the team. This thesis will explore how SM has changed media relations from several different perspectives. The first perspective is related to the risks that are associated with the use of SM by professional athletes: without an intermediary or a filter for athlete-fan communication, many athletes have caused irreparable damage to their reputation and the reputation of their team. The second perspective is related to the benefits for teams that use SM as a platform to connect with fans: the ability to connect with fans using SM is new to sports communications and represents an interactive one-to-one and one-to-many mode of communication through which the fan can directly communicate with the team. Finally, this research will look at how Twitter has changed media relations in sports from the perspective of the lived experiences of people who work in sports media. To explore the risks associated with athletes’ use of social media, this research used Situational Crisis Communication Theory as a theoretical framework to explore reputation-damaging incidents that occurred through social media. The study reviewed national media stories reported in North America from 2009 to 2010 that were perceived to have negative impact on athletes’ reputation. In total, 17 incidents were reviewed — seven incidents in particular demonstrated the athlete as the source of the SM crisis. Through the review and categorization of these 17 situations, the study was able to identify four broad categories of situations that a sports communication manager needs to be prepared for. The four categories identified were “Rookie Reporter”, “Team Insider”, “Opportunist”, and “Imposter”. Each of these categories are invaluable for team communication managers to recognize in order to address the risks associated with social media. To explore the benefits associated with the communications department’s use of social media, this research used Uses and Gratification theory as a theoretical framework to explore how and why fans followed team Twitter accounts. This study was conducted in partnership with the Canadian Football League (CFL) and a total of 526 people responded to an online survey that was tweeted out to them for their feedback. The results of the survey indicated several significant findings — in particular, the phenomenon of converged sports fan consumption was identified, which has not been previously acknowledged in academic research. The phenomenon of converged sports fan refers to the multi-screen environment whereby a sports fan decides where, when, and how they want to consume sporting content. This research identified that in-game consumption of SM while watching television and the mobile consumption of SM are both dominant ways for fans to interact with their teams. This multi-modal format of connecting with the team supports the idea of Henry Jenkins’s Black Box Fallacy (2006, p. 13): as teams move forward in developing communications platforms to reach their fans, they will need to recognize that all channels can and do work together. In order to further understand how Twitter has changed sports media relations, the study used long semi-structured interviews with a phenomenological research design to understand how Twitter has impacted sports media relations. The phenomenological analysis of the informant interviews suggested that Twitter is the source of three themes of change: general media relations, mechanical job functions, and other changes specific to sports media relations. The significance of Twitter’s impact on sports media relations cannot be understated. With the ubiquitous use of SM like Twitter, it is important to understand how sports media relations can use SM to manage the image of their respective teams and athletes. After looking at SM and sports from three different perspectives, the pivotal finding was the role that Twitter and mobile communications play in ‘flattening’ sports media relations. Similar to how Friedman (2006) argued that the convergence of the personal computer drove globalization, Twitter and the increased adoption of mobile communications have flattened the role of sports media relations. This research will explain how the flattening of sports media relations happened and what the implications might be for sports media professionals.

DISSERTATION SUBMITTED IN FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF COMMERCE IN INFORMATION SYSTEMS TO THE FACULTY OF COMMERCE, LAW AND MANAGEMENT UNIVERSITY OF THE WITWATERSRAND, JOHANNESBURG FEBRUARY 2015 / Social Network Sites (SNS) such as Facebook, Instagram, Twitter, Piniterest and Google+ have made it easy for youth to communicate, produce and share information. Using SNS has become a daily activity for many youth and young adults around the world, including South Africa. The use of SNS by youth may be motivated by needs for safety, belonging, self-esteem and self-actualization, and others such as enjoyment. Yet, the use of SNS by youth may also carry a number of risks. They include risks to violations of privacy, social and psychological risks that may harm the user’s self-image, as well as time and financial risks resulting from excessive SNS usage. The purpose of this study is to understand the tension between risks and motivation in the use of SNS by university students. To do so, this study developed an extended Technology Acceptance Model (TAM). Multi-dimensional risk and motivation constructs were examined for their interactions with TAM constructs of perceived ease of use and perceive usefulness and their effects on SNS usage intentions and actual usage were examined. To test the model, a non-probability convenience sampling method was adopted using students from the University of the Witwatersrand, Johannesburg. Five hundred and fifteen students participated in the study. The ages ranged between 18 and 34 years, 26% males and 74% females took part in the study, and included students from 1st year through to 4th year undergraduate or Honours level. Facebook was found to be the most used SNS. Approximately 80% of respondents reported accessing SNS on their mobile phones and 66% reported being always connected. More than 25% of respondents were actively using SNS for more than 3 hours a day, with 35% using less than one hour per day. Interestingly, only 35% reported having public profiles although 10% did not know whether their profiles were public or private, and nearly 40% of respondents knew less than half the “friends” they were connected to on SNS Partial least squares approach to structured equation modelling was used to test the hypothesised research model. Results showed that motivation influences perceived usefulness (β=0.239, p<0.001) and perceived ease of use (β=0.319, p<0.001) positively. The results suggest that when motivations such as enjoyment and need to belong are high, SNS will be perceived as useful and easy to use. Risk was found to have a negative influence on perceived usefulness (β=-0.0764, p<0.05) and perceived ease of use (β=-0.3265, p<0.001). The results show that when risks are considered high, users are likely to increase their vigilance and consequently will report SNS as less easy to use. Moreover, as a result of risk users may find the SNS less useful. Perceived usefulness (β=0.295, p<0.001) influences intention to use SNS positively. This suggests that when SNS is useful to users, they will have intentions to use it. Intention to use SNS is also influenced by perceived ease of use (β=0.0396, p<0.01). An easy to use SNS will make users want to use it, as opposed to one considered more complex and requiring more effort. Motivation (β=0.281, p<0.001) was found to have more of an effect than risk (β=-0.071, p<0.05) on intentions to use. Respondents thus appear to recognize some risks associated with SNS use, but they appear to be driven more by motivations and less by risk avoidance when deciding on SNS usage. The study will have implications for researchers, SNS providers and users. The results of the study have implications for how researchers conceptualize risk and motivation. The study shows how different dimensions of risk and dimensions of motivation affect the overall risk and overall motivation construct respectively. Currently SNS providers may not have deep understanding of the risks which hinder the use of SNS and motivations which drive the use of SNS. Providers will be better informed to design SNS that are less risky and where possible mitigate the risks. Results also show that SNS providers should not only mitigate risks but also provide online social networks that better fulfil motivational needs of youth. Users will be aware of different risks they are exposing themselves to by using SNS. Since users will be aware of the different types of risks, they can be vigilante when using SNS. / MT2017
