Benigni, Matthew Curran. "Detection and Analysis of Online Extremist Communities". Research Showcase @ CMU, 2017. http://repository.cmu.edu/dissertations/949.
Texto completo da fonteResumo:
Online social networks have become a powerful venue for political activism. In many cases large, insular online communities form that have been shown to be powerful diffusion mechanisms of both misinformation and propaganda. In some cases these groups users advocate actions or policies that could be construed as extreme along nearly any distribution of opinion, and are thus called Online Extremist Communities (OECs). Although these communities appear increasingly common, little is known about how these groups form or the methods used to influence them. The work in this thesis provides researchers a methodological framework to study these groups by answering three critical research questions: How can we detect large dynamic online activist or extremist communities? What automated tools are used to build, isolate, and influence these communities? What methods can be used to gain novel insight into large online activist or extremist communities? These group members social ties can be inferred based on the various affordances offered by OSNs for group curation. By developing heterogeneous, annotated graph representations of user behavior I can efficiently extract online activist discussion cores using an ensemble of unsupervised machine learning methods. I call this technique Ensemble Agreement Clustering. Through manual inspection, these discussion cores can then often be used as training data to detect the larger community. I present a novel supervised learning algorithm called Multiplex Vertex Classification for network bipartition on heterogeneous, annotated graphs. This methodological pipeline has also proven useful for social botnet detection, and a study of large, complex social botnets used for propaganda dissemination is provided as well. Throughout this thesis I provide Twitter case studies including communities focused on the Islamic State of Iraq and al-Sham (ISIS), the ongoing Syrian Revolution, the Euromaidan Movement in Ukraine, as well as the alt-Right.

Texto completo da fonteResumo:
Social networking sites and virtual spaces have flourished in the past few years. The author explores the impact of such social networking services on the local community at a small liberal arts college. The author investigates modern trends in community theory. Defining community has become more difficult in modern society, where community is no longer easily distinguished by geographical boundaries. From the background of modern community theory the author explores the designation of virtual spaces as “virtual communities.” Literature and research about virtual spaces indicates that they can provide many of the values thought be to inherent to community membership. The strong localized community on campus makes students hesitant in calling Facebook a “virtual community,” despite its strong integration with the face-to-face community itself. Facebook is seen as simply a tool. This thesis incorporates research on one specific case study: through mathematical and ethnographic research of Facebook.com, the author evaluates the opinions of students in considering virtual spaces as communities.

Texto completo da fonteResumo:
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.

Texto completo da fonteResumo:
The capacity for online learning environments to provide quality learning experiences for students has been the focus of much speculation and debate in the higher education sector from the late 1990s to the present day. In this area, 'quality' has become synonymous with engaging students in a learning community. This study reports on a qualitative research project designed to explore the significance of community for students when they study in online learning environments. This project used three case studies to explore tertiary students' thoughts and expectations about community in the online environment. The research was constructed iteratively. Data from the initial case suggested the need to explore the relationship between the constructed online learning environment and the development of learning communities or what I have termed Social Learning Support Networks (SLSN). To explore this issue further, the project was expanded and subsequent cases were chosen that included fundamentally different types of online learning environments. The project had two significant results. Firstly, students not only confirmed popular educational theories on the value of learning communities, but also described how this form of social connection might practically benefit their learning. Secondly, the project found that certain forms of synchronous online environments provided enhanced opportunities for students to form social connections that supported their learning. This project provides new evidence of the benefit of community for students studying online and argues that future online learning environments should be shaped by five key principles designed to foster a sense of social connection between students.

Kayes, Md Imrul. "Content Abuse and Privacy Concerns in Online Social Networks". Scholar Commons, 2015. http://scholarcommons.usf.edu/etd/5967.
Texto completo da fonteResumo:
Online Social Networks (OSNs) have seen an exponential growth over the last decade, with Facebook having more than 1.49 billion monthly active users and Twitter having 135,000 new users signing up every day as of 2015. Users are sharing 70 million photos per day on the Instagram photo-sharing network. Yahoo Answers question-answering community has more than 1 billion posted answers. The meteoric rise in popularity has made OSNs important social platforms for computer-mediated communications and embedded themselves into society’s daily life, with direct consequences to the offline world and activities. OSNs are built on a foundation of trust, where users connect to other users with common interests or overlapping personal trajectories. They leverage real-world social relationships and/or common preferences, and enable users to communicate online by providing them with a variety of interaction mechanisms.
This dissertation studies abuse and privacy in online social networks. More specifically, we look at two issues: (1) the content abusers in the community question answering (CQA) social network and, (2) the privacy risks that comes from the default permissive privacy settings of the OSNs. Abusive users have negative consequences for the community and its users, as they decrease the community’s cohesion, performance, and participation. We investigate the reporting of 10 million editorially curated abuse reports from 1.5 million users in Yahoo Answers, one of the oldest, largest, and most popular CQA platforms. We characterize the contribution and position of the content abusers in Yahoo Answers social networks. Based on our empirical observations, we build machine learning models to predict such users.
Users not only face the risk of exposing themselves to abusive users or content, but also face leakage risks of their personal information due to weak and permissive default privacy policies. We study the relationship between users’ privacy concerns and their engagement in Yahoo Answers social networks. We find privacy-concerned users have higher qualitative and quantitative contributions, show higher retention, report more abuses, have higher perception on answer quality and have larger social circles. Next, we look at users’ privacy concerns, abusive behavior, and engagement through the lenses of national cultures and discover cross-cultural variations in CQA social networks.
However, our study in Yahoo Answers reveals that the majority of users (about 87%) do not change the default privacy policies. Moreover, we find a similar story in a different type of social network (blogging): 92% bloggers’ do not change their default privacy settings. These results on default privacy are consistent with general-purpose social networks (such as Facebook) and warn about the importance of user-protecting default privacy settings.
We model and implement default privacy as contextual integrity in OSNs. We present a privacy framework, Aegis, and provide a reference implementation. Aegis models expected privacy as contextual integrity using semantic web tools and focuses on defining default privacy policies. Finally, this dissertation presents a comprehensive overview of the privacy and security attacks in the online social networks projecting them in two directions: attacks that exploit users’ personal information and declared social relationships for unintended purposes; and attacks that are aimed at the OSN service provider itself, by threatening its core business.

Nilphan, Pan. "Online communities and social networks : an ethnographic study of a Thai fan community". Thesis, University of Leicester, 2006. http://hdl.handle.net/2381/7375.
Texto completo da fonteResumo:
This thesis investigates how the social networks of Thai fans can be expanded through participation in an online community. We examine not only practices within online communities and social networks, but also broader contexts of the Internet which include fandom. Examining a Thai case illustrates how the use of the Internet is influenced by local contexts and cultures. Thai cultural values are used to explain the online social interactions of the Thai people. An online community of fans of the Thai novel, Petchprauma is selected for study. This community represents a ‘critical case’, where theoretical ideas concerning a decentralised role of the Internet, online fandom and relationships can be studied. This research was conducted using an ethnographic approach. The key methods comprised of non-participant observation, participant observation, textual analysis, and face-to-face interviews. This approach involved intensive participation as a Petchprauma fan both within the online and offline environments of the case study. The data collected from these different viewpoints was triangulated in order to ensure the validity, reliability and consistency of the research findings. This thesis argues that fans can expand their social networks through participation in on and offline activities. However, the degree of social network expansion is dependent on the fans’ positions in the hierarchical structure within the community. The difference in status of the community’s members results from the members’ levels of participations and personal characteristics. This finding also reflects the influential role of the Internet as social technology and as part of people’s daily lives, and as decentralised medium. The original contribution of this thesis is not only the study of the empirical data which provides original information for Thailand where there are a limited number of Internet studies, but also the use of particular analytical tools. Additionally, this thesis examines factors that contribute to different social status within online fan communities to explain the different degrees of social networks expansion of fans.

Ray, Aaron Parker. "Planning Connected: Using Online Social Networks to Improve Knowledge about Places and Communities". DigitalCommons@CalPoly, 2011. https://digitalcommons.calpoly.edu/theses/580.
Texto completo da fonteResumo:
The advent of Social Networking Systems (SNS) has introduced new possibilities for planners to refine and extend conventional engagement and data-gathering techniques by leveraging user-contributed, spatially-referenced content freely available online. This study examines the use of SNS content as community input, complementing input gathered through traditional participatory processes such as workshops, public comment hearings, and charrettes. Four case studies of recent community planning projects in the United States are analyzed, comparing the data gathered from traditional participatory processes with available SNS content related to each project study area, to determine to what extent the inclusion of SNS data would improve the overall data- gathering efforts of these projects. Three significant findings emerge from this analysis: (i) that SNS data analysis can positively complement data gathered from traditional participatory processes, (ii) that although SNS data analysis can provide useful data to planners, it is not a direct replacement for conventional engagement techniques, and (iii) that SNS data analysis is most effective for projects in neighborhoods with a well- defined identity. The study also examines the characteristics of effective SNS data analysis integration and discusses broader implications for planning practitioners and additional research needed.

Texto completo da fonteResumo:
Online social networks are experiencing an explosive growth in recent years in both the number of users and the amount of information shared. The users join these social networks to connect with each other, share, find content and disseminate information by sending short text messages in near realtime. As a result of the growth of social networks, the users are often experiencing information overload since they interact with many other users and read ever increasing content volume. Thus, finding the "matching" users and content is one of the key challenges for social networks sites. Recommendation systems have been proposed to help users cope with information overload by predicting the items that a user may be interested in.
The users' preferences are shaped by personal interests. At the same time, users are affected by their surroundings, as determined by their geographically located communities. Accordingly, our approach takes into account both personal interests and local communities. We first propose a new dynamic recommendation system model that provides better customized content to the user. That is, the model provides the user with the most important tweets according to his individual interests. We then analyze how changes in the surrounding environment can affect the user's experience. Specifically, we study how changes in the geographical community preferences can affect the individual user's interests. These community preferences are generally reflected in the localized trending topics. Consequently, we present TrendFusion, an innovative model that analyzes the trends propagation, predicts the localized diffusion of trends in social networks and recommends the most interesting trends to the user. Our performance evaluation demonstrate the effectiveness of the proposed recommendation system and shows that it improves the precision and recall of identifying important tweets by up to 36% and 80%, respectively. Results also show that TrendFusion
accurately predicts places in which a trend will appear, with 98% recall and 80% precision.Ph. D.

Online communities have grown to be an important feature of modern life, and substantial economic assets in their own right. Over the years, organizations that provide them have adopted a range of management practices, or policies. We propose that the choice of policies to manage an online community can be viewed under the lens of mechanism design. Using both empirical data and computer simulations, we investigate how online community providers might decide to put in place and evaluate such mechanisms.

This paper proposes an audience selection framework for online brand advertising based on user activities on social media platforms. It is one of the first studies to our knowledge that develops and analyzes implicit brand-brand networks for online brand advertising. This paper makes several contributions. We first extract and analyze implicit weighted brand-brand networks, representing interactions among users and brands, from a large dataset. We examine network properties and community structures and propose a framework combining text and network analyses to find target audiences. As a part of this framework, we develop a hierarchical community detection algorithm to identify a set of brands that are closely related to a specific brand. This latter brand is referred to as the "focal brand." We also develop a global ranking algorithm to calculate brand influence and select influential brands from this set of closely related brands. This is then combined with sentiment analysis to identify target users from these selected brands. To process large-scale datasets and networks, we implement several MapReduce-based algorithms. Finally, we design a novel evaluation technique to test the effectiveness of our targeting framework. Experiments conducted with Facebook data show that our framework provides significant performance improvements in identifying target audiences for focal brands.

Texto completo da fonteResumo:
Thesis (MBA)--Stellenbosch University, 2011.The purpose of this study is to identify the user features for an online sports community network. Social networks sites are on a rapid increase. Designers of these sites need to consider what features are critical to optimally facilitate their users’ behaviour on these sites. This identification of features will seek to enhance the growth and development of a site’s social communities and allow for its ultimate success. This study focuses on establishing the social networking ecosystem by identifying the role of social networks in society, the user behaviour trends on social network sites and the key features required for a social network site. Furthermore, the study establishes the role of sports fans in society and digital trends for online sports fans visiting sports sites. This study met the research objectives from the findings gained from relevant literature and the employment of an empirical research study. The latter was carried out by means of an online questionnaire targeting an audience that qualified to be both social media lovers and online sports fans. The research disclosed fundamental findings with regards to the user behaviour and frequency of usage of both social network sites and sports sites. Specifically, it was determined that the technological behaviours in the social technographic profile for online users were aligned to those of the social technographic profile for social media lovers and online sports fans. Consequently, the key features of social network sites and most frequently-used features on sports sites could be used to identify the features required for an online sports community network. The main conclusion drawn from this research was a list of features required for a sports community network. These features were determined for the initial launch phase of a sports community network. Enhancement and development of new features would be required to facilitate the user requirements as the site grows. It is therefore important for the success of the sports community site that the owners or designers continuously review the user requirements and adapt, enhance and develop features as the site gains traction. This research study recommends that the list provided be used for the initial design and launch phase of an online sports community network. This list should be constantly evaluated from a usercentric perspective as the site grows.

Texto completo da fonteResumo:
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.

Texto completo da fonteResumo:
For many faculty, teaching online represents a new instructional delivery method, requiring the development of new teaching skills. This exploratory investigation builds upon Rogers' (2003) Diffusion of Innovations theory and communication channels to describe the influence of faculty discussions on their perceptions and decisions about teaching and learning. A sequential explanatory mixed-methods research design, using both sociometric and phenomenological methodologies, guided the exploration of faculty personal network exposure models and social learning opportunities. The study utilized online survey and open-ended interview instruments for the investigation. Faculty from several colleges at the University of Central Florida voluntarily completed the survey instrument identifying with whom, how, and why they discuss teaching online, including the influence of these discussions. In-depth interviews offered internal descriptions of their personal networks. Survey results established baseline data for demographic and future comparisons and identified concerns, issues, and trends unique to synchronous and asynchronous Internet-based faculty development and support needs. Phenomenological data produced the emergent categories and themes used to investigate and explain faculty's communication channel usage and social learning experiences. Similarities between diffusion and knowledge research findings and participants reflected more conformity than anticipated. Differences in communication channel and learning style preferences and usage and faculty's 24/7 work life needs, present challenges to administrators and educators responsible for providing development and support systems.Ed.D.

Texto completo da fonteResumo:
Criado a partir do trabalho colaborativo de grupos de pessoas, o ciberespaço expressa vocação para abrigar incontáveis agrupamentos, diversos e distintos como a natureza humana. Parte desses agrupamentos tem recebido o nome de redes de aprendizagem online e comunidades virtuais de aprendizagem. Uma vez que a aprendizagem é intrínseca ao homem, em variados tempos, lugares e situações, todos os agrupamentos do ciberespaço podem proporcionar aprendizagens. Mas o fato de que há aspectos em comum na diversidade não retiraria a necessidade de estabelecer diferenças entre os agrupamentos porque não se deve confundir multiplicidade com indistinção. Nesse sentido, esta investigação buscou identificar elementos que podem distinguir as redes e comunidades virtuais de aprendizagem dos demais agrupamentos do ciberespaço. A partir da compreensão de que as palavras são signos ideológicos e que seu emprego formata a realidade (BAKHTIN, 1981), verificamos que também há distinção entre redes de aprendizagem online e comunidades virtuais de aprendizagem. A reflexão proporcionou ainda mapearmos indicadores de formação de comunidades virtuais em situação de aprendizagem. Para levantar os elementos mencionados, realizamos revisão bibliográfica e examinamos três agrupamentos do ciberespaço, apontados neste trabalho como uma rede social, uma rede de aprendizagem online e uma comunidade virtual de aprendizagem. Mais do que apresentar uma sugestão quanto ao emprego dessas expressões, esta dissertação costura uma série de reflexões sobre rede e intencionalidade educativa, certos de que rede é a metáfora mais fundamental para a Educação do século XXI.Elaborated from co-operated work by groups of people, the cyberspace expresses the vocation to shelter countless groupings, several and different as the human nature. Some of these groupings have been receiving the name of online learning networks and virtual learning communities. Once the learning is intrinsic to the man, in several times, places and situations, all groupings of the cyberspace can provide learning. But the fact that there are aspects in common in the diversity would not remove the need to establish differences among the groupings because it should not confuse multiplicity with indistinct. In that sense, this investigation looked for to identify elements that can distinguish the online learning networks and the virtual learning communities of the other groupings of the cyberspace. Starting from the understanding that the words are ideological signs and that its use formats the reality (BAKHTIN, 1981), we verified that there is also distinction between online learning networks and virtual learning communities. The reflection provided mapping of indicators of virtual communities\' formation in learning situation. To survey the mentioned elements, we accomplished bibliographical revision and examined three groupings of the cyberspace, pointed in this work as a social network, an online learning network and a virtual learning community. More than to present a suggestion for the use of those expressions, this dissertation sews a series of reflections on net and educational intentionality, convinced that net is the most fundamental metaphor for the Education of the XXI century.

Martin, Sarah Ruth. "Community Connections: Exploring the Constructive Potential of Facebook for Civic Engagement". PDXScholar, 2014. https://pdxscholar.library.pdx.edu/open_access_etds/1987.
Texto completo da fonteResumo:
Recognizing the importance of civic engagement to the health of local communities and the overall success of a democracy, this research sought to better understand the relationship between online media use and civic engagement. Specifically, the constructive potential of the social networking site Facebook was explored using the theoretical framework of communication infrastructure theory (CIT; Ball-Rokeach, Kim, & Matei, 2001). Results of a cross-sectional survey with a national sample of 375 participants indicated that Facebook does hold potential for civic engagement. The two most important findings of the research were that Facebook facilitated connection to neighborhood storytelling and that connection to storytelling was positively associated with civic engagement. As such, results indicated that Facebook holds potential for civic engagement insofar as the site facilitates connection to neighborhood storytelling. Additionally, Facebook was a regular part of participants’ daily routines, a means to maintain social capital, and a forum for occasional civic participation. Cumulatively, these results highlight a number of strengths that citizens and communities can build upon to improve social capital and increase civic engagement.

Askander, Gloria. "What significance does physical activity and sedentary behaviour have for members of online health promoting communities? Learning from AustraIia’s HeartNET community". Thesis, Edith Cowan University, Research Online, Perth, Western Australia, 2015. https://ro.ecu.edu.au/theses/1669.
Texto completo da fonteResumo:
My study used the HeartNET (HN) community to investigate the significance of physical activity and sedentary behaviour for members of online health-promoting communities by using online surveys and netnography. It found concerns about heart health and general health can be both a barrier and an enabler to increasing physical activity or reducing sedentary behaviour.
Gentle efforts to address sedentary behaviour could build confidence to increase physical activity. By offering role models and encouraging friendly rivalry, peer support via an online community (or other type of social networking sites) can increase physical activity and reduce sedentary behaviour. Fun, laughter and peer support can assist in challenging and reducing the tendency to underestimate sedentary behaviour and its health hazards as well as the fear and uncertainty and the perceived constraints to engage with physical activities.
My study highlighted both the value of netnography as an analytic tool and its potential use for strategic and tailored health promoting interventions in online communities and for interventions in other online environments to promote desired behaviours stipulated by community guidelines. Such gentle and respectful interventions would need to take careful account of factors such as age, gender and the individual’s role within the online community.
This study has particular relevance for users of online health-promoting communities and organisations engaged in health promoting activities, especially those operating online and seeking to minimise risks to their members’ health. This research may also encourage online communities and other social networks not focused on health promotion to consider developing strategies to reduce prolonged sitting time and encourage healthier behaviours. Follow-up studies are needed to determine the sustainability and applicability of my conclusions and recommendations in emerging online communities, where smartphones and ‘apps’ are the primary means of internet access, and where wristbands can conveniently and unobtrusively monitor physical activity and sedentary behaviour.

Texto completo da fonteResumo:
This paper’s chief focus lays in essence, in the examination of what the eventual relevance of the internet has for refugee youth in Sweden, regarding the realisation of a sense of community and participation therein. Rather than acquiring grounds with which to make generalisations feasible, it is an approach towards attaining a better comprehension in understanding the significance of a youth’s views and perceptions, through which ultimately also their internalisation, of the internet as a medium towards eventual capitalisation of the cybersocial potential. However, by ‘sense of community’, this primarily refers to interactional and relational aspects, rather than on premises of eventual membership within forums that may in turn prove to be ’dormant’.

Texto completo da fonteResumo:
In an attempt to shed light on the further sophistication of opinion leadership in online communities, this study examined the forces and structures that affect their formation in the League of Legends subreddit. By investigating what users thought about the various types of individuals with which the communicate, the researcher hoped to begin to understand and record how those forces work bother on this particular subreddit and in mass media beyond. Opinion leadership continues to be an integral force in deciding what information is consumed by a public and under what frames and agendas it is contextualized. If researchers can operationalize formal definitions for the influences and structures that occur online, they can better navigate the deep waters that are global communication on the internet.

GeNeMe steht für Gemeinschaften in Neuen Medien, im englischen Sprachgebrauch bezeichnet als Web-based Communities oder Online Communities. Einen wichtigen Impuls erfuhren die wissenschaftliche Analyse und die wirtschaftliche Nutzung dieser Communities unter der Metapher des Web2.0. Internet-basierte Technologien wie z. B. Social Media Werkzeuge, aber auch (soziale) Intranet-Systeme und Wissensplattformen bestimmen mehr denn je Lernen, Forschen und Arbeiten in Wirtschaft, Wissenschaft und Bildung und insbesondere das private (Zusammen-) Leben. Dabei führt die zunehmende Mobilität moderner multimedialer Systeme (Smartphone, Tablet PC, etc.) zu neuen Nutzungsoptionen und kollaborativen Anwendungen - sei es im Bereich des Gaming, der Barrierefreiheit oder beim gemeinsamen Gestalten digitaler Produkte.
Die GeNeMe ’13 richtet sich in gleichem Maße an Wissenschaftler und Praktiker, die sich über den aktuellen Stand der Arbeiten auf dem Gebiet der Gemeinschaften in Neuen Medien informieren möchten. Im 16. Jahr der Tagung geht es weiterhin um Fragen der (Ver-)Gemeinschaftung bei der Nutzung neuer Medien, virtueller Communities und des Social Web. Unabhängig von der sektoralen Zugehörigkeit der behandelten Szenarien zu Wirtschaft, Wissenschaft, Bildung und Unterhaltung geht es schwerpunktmäßig um folgende Themen:
• Research Communities
• Multi- and Rich Media Communication/Collaboration in mobilen Anwendungsszenarien und Kollaborative Barrierefreiheit
• Global Communities, transnationale Kooperationen und - Netzwerke
• Virtual and Massive Communities in Education
Neben der methodischen und technologischen Perspektive interessiert das Verhältnis von individueller versus gemeinschaftlicher Aktivität, respektive Nutzung. Stärker als 2012 wurde auch die themenbezogene Praxis von Communities berücksichtigt. Der Sammelband zur Tagung „Gemeinschaften in Neuen Medien“ steht 2013 unter dem Rahmenthema „Online Communities: Enterprise Networks, Open Education and Global Communication“ und strukturiert sich in Beiträge zu den Themenfeldern Community Technologies, Community Topics und Community Didactics.

Texto completo da fonteResumo:
GeNeMe steht für Gemeinschaften in Neuen Medien, im englischen Sprachgebrauch als Web-based Communities oder Online Communities bezeichnet. Diese Konfigurationen aus Informationstechnologie und sozialer Gemeinschaft sind gleichermaßen Thema für Anwendung und Forschung. Dabei wird deutlich, dass diese Konfigurationen aus Informationstechnologie und sozialer Gemeinschaft in vielfältigen Kontexten zu beobachten sind. Online Communities sind ohne Softwaretechnologie nicht denkbar - ebenso wenig wie ohne die neue Kultur gemeinschaftlichen Online-Handelns in Wirtschaft, Forschung und Bildung oder in privaten Räumen. Online Communities sind daher Thema mehrerer Fachdisziplinen: Informatik und Wirtschaftswissenschaft, Bildungswissenschaft und natürlich Kommunikationswissenschaft. Auf der GeNeMe trifft Medien- und Softwaretechnologie auf Wirtschaftsinformatik, Sozial- und Erziehungswissenschaft, werden Wissensarchitektur und -kooperation diskutiert. Diese Interdisziplinarität ist Tradition und Stärke der GeNeMe auch im 17. Jahr ihres Bestehens. Die Schwerpunkte des vorliegenden Bandes widmen sich eingangs überblicksartig der Analyse und Exploration von Trends und der Ausdifferenzierung von Forschungsfeldern. In den folgenden Kapiteln stehen dann zum einen die Beobachtung und Analyse von Informations- und Kommunikationshandeln unterschiedlicher Zielgruppen sowie zum anderen praktische Ansätze zur technologisch-didaktischen Gestaltung kollaborativer Systeme im Vordergrund. Nach Beiträgen aus spezifischen Einsatz- bzw. Forschungsfeldern bilden Analysen zu Nutzerverhalten in Business-Netzwerken sowie zu Geschäftsmodellen für MOOCs den Abschluss.:Inhalt

Mano, Mattias. "How does the crowd debate and consent in an open online context? A case study : Reddit – Change My View". Thesis, Institut polytechnique de Paris, 2020. http://www.theses.fr/2020IPPAX082.
Texto completo da fonteResumo:
L’émergence d’Internet a révolutionné une grande partie de la vie des individus, en touchant tous les aspects, notamment sur la façon de communiquer. Depuis les premiers newsgroups des années 1980 aux réseaux sociaux, les individus échangent quotidiennement des informations en ligne. Par ailleurs, différents événements politiques de part le monde, comme le mouvement des Gilets Jaunes en 2018, ou le scandale dit de Cambridge Analytica la même année, ont mis en exergue la place de l’espace Internet comme moyen d’expression de la sphère politique de nos sociétés. En dehors de la sphère politique, nous observons d’autres impact d’Internet sur la collaboration entre individu. Wikipedia, encyclopédie en ligne, est le résultat d’actions individuelles. Elle rassemblait déjà à la fin de 2018 plus de 35 millions de contributeurs. Tous ces phénomènes permettent d’étudier la notion d’intelligence collective. C’est l’objectif de ce travail doctoral, qui porte sur l’étude de l’émergence de l’intelligence collective au sein des fora ouvert en ligne. Le cas présenté dans cette thèse est celui du forum Reddit –Change My view, où un individu présente son opinion sur un sujet et demande à la communauté de lui apporter les arguments nécessaires à ce qu’il change d’avis. Ce cas d’étude permet d’analyser d’abord le cycle de vie des communautés en ligne. Mais également les différentes façons de débattre sur ce forum. Et enfin, nous y étudions le processus de cette communauté à établir un consensus entre ces membres. Ce dernier point nous a permis de faire émerger un nouveau concept : le Consentement de la FouleThe development of the Internet revolutionized multiple aspects of daily life, and particularly how one communicates with another. From the 1980s and the first newsgroup to today’s online social networks, people commonly exchange message online. Different political events over the world,such as the movement of the « Gilets Jaunes » in France, 2018, or the Cambridge Analytica scandal, the same year, highlight the place of Internet such as a powerful expression vector on the political sphere.Besides, we observe other impacts on the collaboration among individuals, through Internet. Wikipedia, the most popular online encyclopedia, is mainly the result of individual production. It counted at the end of 2018 more than 35 millions of registered users.All these phenomena highlight the notion of collective intelligence. The purpose of this doctoral work is to study the emergence of collective intelligence within open online fora. The case study Reddit –Change My View, is a forum where an individual exposes his opinion on a subject and asks to the community to bring him arguments to change his opinion.This case study allows to analyze the life cycle of online communities. But also the different processes leading to a constructive debate. Third, we study the process of this community to establish a consensus among his members. This last point highlighted a new concept: the Consent of the Crowd

Nagel, Lynette. "The dynamics of learner participation in a virtual learning environment". Thesis, University of Pretoria, 2008. http://hdl.handle.net/2263/22951.
Texto completo da fonteResumo:
While online students should take charge of their own learning and form collaborative learning communities, constructivist instructors should scaffold online learning without dominating course discussions. This research continues the longitudinal investigation of web-based courses at the Faculty of Education, University of Pretoria. The mixed methodological approach this investigation followed consisted predominantly of qualitative methods, augmented with quantitative approaches. I used two distinct online tools to explore student participation in an eight-week online Masters’-level course delivered via the WebCT™ platform. First, I reviewed the use of metaphors in the literature by a framework of requirements for successful online learning. The use of metaphor supports constructivism, facilitates course interaction, helps to avoid students’ initial inertia in online discussions, and contributes to the development of virtual learning communities. I researched how an explanatory metaphor as tool supported online participation and indicated that metaphors eased students’ communication of important and difficult issues. Secondly, I used the tool of a covert virtual student that also acted as an additional facilitator and course helper. I examined the ethical implications of the carefully concealed real identity of the mythical online helper, methical Jane. As she took part in all course activities and assignments, as well as providing her co-students with cognitive and technical support, the students accepted and integrated her presence in their virtual learning community. I consequently analysed students’ reactions to her identity after disclosure of her origin after the course. Although the exposure precipitated students’ shock, disbelief and dismay as she was a convincing virtual student, they did not object to the presence of a virtual student, but rather felt betrayed due to her hidden real identity. The benefits of this teaching intervention include experts supplying technical expertise, multiple faculty enriching the learning experience, and support and teaching assistants and tutors participating with smaller groups in large online classes. I further examined how frequency of course access, discussion postings, collaborative behaviour and integration into a virtual learning community relate to learning and course completion. Quantitative indices indicated highly significant differences between the stratifications of student performance. Absent and seldom-contributing students risked missing the benefits of the online learning community. Students were discontent with peers who rarely and insufficiently contributed to group assignments. Low participation varied from only reading, skimming, or deliberately harvesting others’ contributions, to high student contributions of little value. Conclusions on the formation of an online learning community indicate that the passport to membership of the community is quality participation, rather than prior peer acquaintance. I indicated that students’ learning benefited from contributing high quality inputs to online learning communities while students with poor participation did not benefit from the online learning community. Online facilitators contribute to students’ learning through the timeliness and quality of tailored scaffolding. Recommendations for future research include uncovering the reasons for students’ stressful experiences of online learning; the effect of online assessment on student course participation; the alignment of learning metaphors in multi-cultural learning environments; and the support of non-participating online students.Thesis (PHD)--University of Pretoria, 2009.

Dillon, Kenneth Walter. "A study of the role of an online community in the community in the professional learning of teacher librarians". University of Southern Queensland, Faculty of Education, 2005. http://eprints.usq.edu.au/archive/00001422/.
Texto completo da fonteResumo:
The thesis has its origins in a concern that teacher librarians in schools throughout Australia were disadvantaged in the development of their professional learning due to their professional and often geographical isolation in schools. A listserv (online discussion network) called OZTL_NET was developed to facilitate the enhancement of teacher professional learning for this group of teachers. OZTL_NET has been available to teacher librarians and others interested in teacher librarianship for over nine years. The study sought to determine whether usage of OZTL_NET was associated with the enhancement of teacher librarians’ professional learning. The study also explored the characteristics of teacher professional learning from the literature and sought to determine which characteristics of online communities may contribute to teacher professional learning. A case study design for the research was adopted using a mixed methods approach. The methods of data collection were a web survey and semi-structured interviews. Quantitative and qualitative data were collected and analysed and a detailed description of the object of study, OZTL_NET, was provided. A major finding of this study was that usage of OZTL_NET was significantly related to the enhancement of teacher professional learning. It was concluded that online learning communities may provide appropriate contexts for teacher professional learning and that, in relation to the case of OZTL_NET, various aspects of the concept of online learning communities and, to a lesser extent, communities of practice, are portrayed in the listserv. The findings supported the assertion that online learning communities have the potential to enhance the professional learning of teachers and provide opportunities for teachers to learn online. The study also revealed that community building online is a complex and demanding activity. Usability and sociability factors must be carefully considered and developed over the lifetime of the community. This process should include input from the community, the leadership of which should be broad-based and inclusive. Two broad principles emerged from the research that provide guidance for the management of listservs for teacher professional learning online. First, the study revealed that involvement and collaboration were critical ingredients in teacher professional learning online. Involvement was portrayed not only in the learning that ensued from the interactivity that necessarily underpins the sharing of tacit knowledge through information exchange and professional discussion between and among subscribers online but also by individuals through less obvious means such as lurking, archive searches and off-list communications. In terms of collaboration, this study found that in addition to high levels of trust, subscribers experienced a strong sense of collegiality and support as members of OZTL_NET. Second, the major finding above confirms that involvement and collaboration are strongly related to individual and collective orientations of teacher professional learning. The broad concept of individual or collective orientation recognises that teacher professional learning occurs in both orientations online as it does offline. Teachers have long recognised their colleagues as their major source of professional information. The difficulty in the past has been in the identification of a means by which teachers can readily access a wider pool of colleagues with whom they can discuss important issues, seek advice and so on. This is particularly important for teachers who are professionally isolated as a consequence of their teaching speciality (such as teacher librarians) and those who are geographically isolated making real time meetings with colleagues expensive and/or impracticable. In this context listservs such as OZTL_NET can play a critical role in providing the infrastructure to support distributed models of teacher professional learning online.

This thesis explores network science methods and media and communication theory to investigate structures and dynamics of national and global publics. It does so in two studies: one regarding the sharing of hashtags and links on Twitter around acute events, such as the Sydney Siege; the other about communities, publics, and possible echo chambers in the Australian Twitter follower network. It leads to new evidence about structures and dynamics within communities and the public sphere on Twitter, revealing the epistemological implications of network analysis algorithms and outlining a methodological framework to better connect media and communication studies with network science.
