Over the last few years Facebook has become a widespread and continuously expanding medium of communication. Being a new medium of social interaction, Facebook produces its own communication style. My focus of analysis is how Facebook users from the city of Malaga create this style by means of phonic features typical of the Andalusian variety and how the users reflect on the use of these phonic features. This project is based on a theoretical framework which combines variationist sociolinguistics with CMC to study the emergence of a style peculiar of the online social networks. In a corpus of Facebook users from three zones of Malaga, I have analysed the use of non-standard phonic features and then compared them with the same features in a reference corpus collected on three beaches of Malaga. From this comparison it can be deduced that the analysed social and linguistic factors work differently in real and virtual speech. Due to these different uses we can consider the peculiar electronic communication of Facebook as a style constrained by the electronic medium. It is a style which serves the users to create social meaning and to express their linguistic identities.

Social networks offer horizontal integration for any mobile platform providing app users with a convenient single sign-on point. Nonetheless, there are growing privacy concerns regarding its use. These vulnerabilities trigger alarm among app developers who fight for their user base: While they are happy to act on users’ information collected via social networks, they are not always willing to sacrifice their adoption rate for this goal. So far, understanding of this trade-off has remained ambiguous. To fill this gap, we employ a discrete choice experiment to explore the role of Facebook Login and investigate the impact of accompanying requests for different information items / actions in the mobile app adoption process. We quantify users’ concerns regarding these items in monetary terms. Beyond hands-on insights for providers, our study contributes to the theoretical discourse on the value of privacy in the growing world of Social Media and mobile web.

For smart cities applications, a key requirement is to disseminate data collected from both scalar and multimedia wireless sensor networks to thousands of end-users. Furthermore, the information must be delivered to non-specialist users in a simple, intuitive and transparent manner. In this context, we present Sensor4Cities, a user-friendly tool that enables data dissemination to large audiences, by using using social networks, or/and web pages. The user can request and receive monitored information by using social networks, e.g., Twitter and Facebook, due to their popularity, user-friendly interfaces and easy dissemination. Additionally, the user can collect or share information from smart cities services, by using web pages, which also include a mobile version for smartphones. Finally, the tool could be configured to periodically monitor the environmental conditions, specific behaviors or abnormal events, and notify users in an asynchronous manner. Sensor4Cities improves the data delivery for individuals or groups of users of smart cities applications and encourages the development of new user-friendly services.

Cybermobbing ist ein brisantes Thema, das seit über einem Jahrzehnt weltweit für Aufsehen sorgt. Es handelt sich um eine elektronische Mobbingvariante, die vom Versenden einer beleidigenden SMS bis hin zum Veröffentlichen von peinlichen Videos auf YouTube oder Facebook geht. Cybermobbing kann als ungünstiges Nebenprodukt des gesellschaftlichen Wandels hin zur digitalen Kommunikation gesehen werden. Cybermobbing ist deswegen nicht nur ein individuelles, sondern auch ein gesellschaftliches Problem, das in diesem größeren Rahmen betrachtet werden muss. Sowohl das Individuum als auch die Familie, die Gleichaltrigen, die Schule und der gesellschaftliche Kontext sind wichtige Akteure einerseits bei Entstehung und Aufrechterhaltung von Cybermobbing, andererseits bei dessen Prävention und Intervention.

On online social networks such as Facebook, massive self-disclosure by users has attracted the attention of industry players and policymakers worldwide. Despite the impressive scope of this phenomenon, very little is understood about what motivates users to disclose personal information. Integrating focus group results into a theoretical privacy calculus framework, we develop and empirically test a Structural Equation Model of self-disclosure with 259 subjects. We find that users are primarily motivated to disclose information because of the convenience of maintaining and developing relationships and platform enjoyment. Countervailing these benefits, privacy risks represent a critical barrier to information disclosure. However, users’ perception of risk can be mitigated by their trust in the network provider and availability of control options. Based on these findings, we offer recommendations for network providers.

Since the emergence of the Internet and Social Media, privacy concerns and need for regulation in this area have been a frequent subject on the agenda of numerous stakeholders and policy-makers worldwide. Contributing to this debate, this paper builds on the responses of 553 Internet users to uncover users’ current privacy concerns and their attitudes towards legal assurances in this context. Our findings suggest that users have a complex attitude towards these issues. While they express strong concerns about privacy when asked directly, they often have difficulties formulating the exact nature of these concerns. In the Facebook context, Facebook itself is often mentioned as the primary source of threat, closely followed by marketing organizations. Users feel ill-protected by existing legal framework, especially when using Social Networking Sites. Reasons include common beliefs that the law is unable to address complexities of the Internet; local character of laws; possibilities to disregard the law, particularly since enforcement is difficult. Overall, positive changes in legal framework are desirable, with many respondents willing to pay more in taxes to ensure progress in this area.

As Social Network Sites (SNS) permeate our daily routines, the question whether participation results in value for SNS users becomes particularly acute. This study adopts a 'participation-source-outcome' perspective to explore how distinct uses of SNS generate various types of social capital benefits. Building on existing research, extensive qualitative findings and an empirical study with 253 Facebook users, we uncover the process of social capital formation on SNS. We find that even though active communication is an important prerequisite, it is the diversified network structure and the increased social connectedness that are responsible for the attainment of the four benefits of social capital on SNS: emotional support, networking value, horizon broadening and offline participation. Moreover, we propose and validate scales to measure social capital benefits in the novel context of SNS.

By enabling connections between individuals, Social Networking Sites, such as Facebook, promise to create significant individual as well as social value. Encouraging connections between users is also crucial for service providers who increasingly rely on social advertising and viral marketing campaigns as important sources of their revenue. Consequently, understanding user’s network construction behavior becomes critical. However, previous studies offer only few scattered insights into this research question. In order to fill this gap, we employ Grounded Theory methodology to derive a comprehensive model of network construction behavior on social networking sites. In the following step we assess two Structural Equation Models to gain refined insights into the motivation to send and accept friendship requests – two network expansion strategies. Based on our findings, we offer recommendations for social network providers.

Unprecedented success of Online Social Networks, such as Facebook, has been recently overshadowed by the privacy risks they imply. Weary of privacy concerns and unable to construct their identity in the desired way, users may restrict or even terminate their platform activities. Even though this means a considerable business risk for these platforms, so far there have been no studies on how to enable social network providers to address these problems. This study fills this gap by adopting a fairness perspective to analyze related measures at the disposal of the provider. In a Structural Equation Model with 237 subjects we find that ensuring interactional and procedural justice are two important strategies to support user participation on the platform.

Worldwide social networks, like Facebook, face fierce competition from local platforms when expanding globally. To remain attractive social network providers need to encourage user self-disclosure. Yet, little research exists on how cultural differences impact selfdisclosure on these platforms. Addressing this gap, this study explores the differences in perceptions of disclosure-relevant determinants between German and US users. Survey of Facebook members indicates that German users expect more damage and attribute higher probability to privacy-related violations. On the other hand, even though American users show higher level of privacy concern, they extract more benefits from their social networking activities, have more trust in the service provider and legal assurances as well as perceive more control. These factors may explain a higher level of self-disclosure indicated by American users. Our results provide relevant insights for the social network providers who can adjust their expansion strategy with regard to cultural differences.

Las nuevas tecnologías y el procesamiento digital han facilitado considerablemente la lingüística de corpus, por ejemplo Internet es una herramienta fácil y barata para recopilar corpus. Internet es cada vez más popular y más importante para la comunicación a causa de la enorme influencia de los nuevos medios y ha afectado la vida y la sociedad de muchas maneras y en parte, de manera fundamental. No sorprende por eso que la lengua y la comunicación misma se vean afectadas. Uno de los fenómenos más interesantes dentro de la comunicación mediada por ordenadores (CMC) son las redes sociales en línea, que en pocos años se han convertido en un medio de comunicación muy difundido y en expansión continua. Su estudio es particularmente interesante porque debido al desarrollo constante de la tecnología las redes sociales en línea no son una entidad estática, sino que cambian incesantemente, introduciéndose frecuentemente novedades para su uso. Estas novedades están condicionadas por el medio electrónico que a su vez influye decisivamente en el estilo de comunicación empleado en redes sociales como Facebook y Tuenti. Al ser un nuevo medio de interacción social, las redes sociales en línea producen un estilo de comunicación propio. El objetivo de análisis de mi tesis es cómo los usuarios de Facebook y Tuenti de la ciudad de Málaga crean este estilo mediante el uso de rasgos fónicos propios de la variedad andaluza y de qué manera la actitud lingüística de los usuarios influye en el uso de dichos rasgos fónicos. Este estudio se basa en un corpus elaborado a partir de enunciados de informantes en Facebook y Tuenti. Un corpus constituido por transcripciones amplias de grabaciones de hablantes malagueños me sirve de corpus de comparación. Otra herramienta metodológica empleada para recopilar datos será la encuesta: un tipo de encuesta estará destinada a captar las actitudes de los participantes frente a diversos rasgos del habla andaluza/malagueña y otro a examinar por qué la gente utiliza estos rasgos en Facebook y Tuenti. Este estudio se apoya en los resultados de un estudio piloto que muestran que los factores sociales y lingüísticos analizados funcionan de manera distinta en el habla real y virtual. Debido a estos usos diferentes podemos considerar la comunicación electrónica de Facebook y Tuenti como un estilo condicionado por el tipo de espacio virtual. Se trata de un estilo que sirve a los usuarios para crear significado social y para expresar sus identidades a partir de la lengua.

Internet has affected our lives and society in manifold ways, and partly, in fundamental ways. Therefore, it is no surprise that one of the affected areas is language and communication itself. Over the last few years, online social networks have become a widespread and continuously expanding medium of communication. Being a new medium of social interaction, online social networks produce their own communication style, which in many cases differs considerably from real speech and is also perceived differently. The focus of analysis of my PhD thesis is how social network users from the city of Malaga create this virtual style by means of phonic features typical of the Andalusian variety of Spanish and how the users’ language attitude has an influence on the use of these phonic features. The data collection was fourfold: 1) a main corpus was compiled from 240 informants’ utterances on Facebook and Tuenti; 2) a corpus constituted of broad transcriptions of recordings with 120 people from Malaga served as a comparison; 3) a survey in which 240 participants rated the use of said phonetic variants on the following axes: “good–bad”, “correct–incorrect” and “beautiful–ugly” was carried out; 4) a survey with 240 participants who estimated with which frequency the analysed features are used in Malaga was conducted. For the analysis, which is quantitative and qualitative, ten variables were chosen. Results show that the studied variants are employed differently in virtual and real speech depending on how people perceive these variants. In addition, the use of the features is constrained by social factors. In general, people from Malaga have a more positive attitude towards non-­‐standard features if they are used in virtual speech than in real speech. Thus, virtual communication is seen as a style serving to create social meaning and to express linguistic identity. These stylistic practices reflect an amalgam of social presuppositions about usage conventions and individual strategies for handling a new medium. In sum, the virtual style is an initiative deliberately taken by the users, to create their, real and virtual, identities, and to define their language attitudes towards the features of their variety of speech.

Das Internet wird ein immer populäreres und wichtigeres Kommunikationsmittel, besonders die sogenannten Social-Networking-Sites. In dieser Studie wird untersucht wie die Social-Networking-Sites, Facebook und Tuenti, die Kommunikation beeinflussen. In einem Korpus von Usern aus Málaga, wurde der Gebrauch von nicht-Standard Merkmalen analysiert und mit dem in der gesprochenen Sprache verglichen. Aus diesem Vergleich lässt sich schließen, dass die untersuchten sozialen und linguistischen Faktoren in der virtuellen und der reellen Sprache unterschiedlich funktionieren. Aufgrund dieses unterschiedlichen Gebrauchs kann die elektronische Kommunikation Facebook und Tuenti’s als Stil betrachtet werden, welcher den Usern dazu dient, soziale Bedeutung zu kreieren und ihre sprachliche Identität auszudrücken.

Research findings on how participation in social networking sites (SNSs) affects users’ subjective well-being are equivocal. Some studies suggest a positive impact of SNSs on users’ life satisfaction and mood, whereas others report undesirable consequences such as depressive symptoms and anxiety. However, whereas the factors behind the positive effects have received significant scholarly attention, little is known about the mechanisms that underlie the unfavorable consequences. To fill this gap, this study uses social comparison theory and the responses of 1,193 college-age Facebook users to investigate the role of envy in the SNS context as a potential contributor to those undesirable outcomes. Arising in response to social information consumption, envy is shown to be associated with reduced cognitive and affective well-being as well as increased reactive self-enhancement. These preliminary findings contribute to the growing body of information systems research investigating the dysfunctional consequences of information technology adoption in general and social media participation in particular.
