Growing an online community takes time and effort. Relationships in an online community must be initiated based on trust followed by privacy, and then carefully cultivated. People are using web based social networks more than recent past, but they always want to protect their private data from unknown access; meanwhile also eager to know more people whom they are interested. Among all other system, trust based recommenders have been one of the most used and demanding system which takes the advantage of social trust to generate more accurate predictions. In this work we have proposed for Meven (An Enterprise trust-based profile recommendation with privacy), which uses Social Network Content (User Profiles and trends) with Trust and privacy control policy. The idea of system is to provide Social Networks with the ability to quickly find related information about the users having similar behaviors as the current user. The users will also be able to set the privacy metrics on their profiles so they will not get recommendation of those they feel less important and this is achieved by Privacy metrics. To generate accurate predictions, we defined trust between two users as a strong bond which is computed using different metrics based on user’s activities with respect to different content such as blogging, writing articles, commenting, and liking along with profile information such as organization, region, interests or skills. We have also introduced privacy metric in such a way so that users have full freedom to hide themselves from the recommendation system or they can also have the opportunity to customize their profiles to be visible to certain level of trustworthy users. We have exposed our application as a web service(api) so that any social network web portal can access the recommendations and publish them as a widget in social network.

Innovation as the most important way for firms to retain their long-term competitiveness has been extensively researched lately. In this thesis, the author perceived innovation from the bottom up approach, where innovation spans over a broad spectrum of actors, reaching the initiative at a very low level. From this perspective, although innovation starts from an initial idea within an individual’s mind, the connections and interactions between individuals in a social context are very important for idea generation and innovation implementation. Thus social links and interaction within the enterprise context hold an important role in the firms’ innovation. Enterprise Social Network (ESN), defined as “a set of technologies that creates business value by connecting the members of an organization through profiles, updates, and notifications”, comes as one strategy to facilitate professional social networking activities within firms to support better collaboration and communication. However, nowadays when social networking becomes very popular, theimplementation of ESN appears more of a trend for firms instead of a well planned strategy. Most ESN implementations lack means of evaluation of their impacts towardthe firms’ performance, including innovation. In response to that, this thesis’s aim is to answer the ‘how’ question on ESN support toward 9 innovation climate characteristics and social interaction within firm. In this research, an interpretive research methodology was applied towards a case in a global telecom company, Ericsson, with their ESN called MyNET. As part of the methodology, a survey and interviews were done to assess MyNET users’ experience and opinion in this matter. The social network graph was also used in this methodology as an additional input for the interviews. There were 672 respondents participating in the survey and 10 interviews were conducted. The results show that the targeted goals of MyNET implementation support innovation climate characteristics. The results also show that professional social networking activities supported by MyNET such as individual user profile, add colleague in the social network, share information, ask and answer questions, join community, etc, provide an innovative way for social interaction supporting better communication and collaboration which is important for innovation in a global ompany.

The economic capital, cultural capital especially social capital have significant effect on forming the small-sized Chinese city. This article argues for understandings of the spatial form of capital based on the special context in China and mainly focuses on social network in the scale of neighborhood. Reviews of documentation in the city discussed are exemplified as firsthand data for case study. Furthermore, the qualitative narration concerning five elements of social capital- “social network, trust, security, sense of belonging and participation”-is adopted as useful lens for evaluating the existing situation and better involvement of social capital in space is prompted as an effective solution. An overall assessment of the performance of social capital in the case is concluded and recommendations are presented for future improvement of enhancing social capital onsite.

The sharing economy, or collaborative consumption, refers to peer-to-peer sharing of goods and services coordinated through a commercialized or community-based online platform. Collaborative consumption platforms are used for sharing of our under-used assets, e.g. our homes, tools, and vehicles, and can bring social communities together. Through sharing we use our resources more effectively, and contribute towards a more sustainable lifestyle. Hoffice was started in 2013 in Stockholm and promotes the concept of working for free in the homes of others, and is getting a lot of attention around the world. This nonprofit network helps people arrange home offices, where hosts share their residence with people who, through Facebook, can reserve a seat for the day. The purpose of these work events is to create free workspaces, with the possibilities for social, structured and disciplined environments, while allowing individuals to benefit from the support and intelligence of others. This research aims to study the hosts in the Hoffice network, to find ways to explain the key driving values, as well as barriers, and apply it to a tailored platform in order to motivate more people to host work events. The central research question is furthermore How could well adapted social platforms increase motivation for people to engage in the collaborative consumption as exemplified by Hoffice? Six semi-structured interviews with past host from year 2014-2015 were conducted to gain qualitative answers about how an online platform can be developed in order to motivate Hoffice members to become hosts. The questions were divided into three different sections; Background, About Hoffice, and Online platform. Observations were performed with a purpose of understanding the structure of a Hoffice event, and to gain a better understanding of the users needs and behaviors. After a first version of a prototype was developed, evaluations and user tests were completed with the interviewees and the founder of Hoffice. Results show that communication, offline and online, is important when people engage in collaborative consumptions, and Facebook has a great impact on people when communicating and spreading information. Although Facebook has some weaknesses when it comes to planning and inviting people to events due to their restrictions and functionalities. Also, when using Facebook for a sharing service, the users are forced to have a Facebook account to partake. All services that involve sharing should consider and support geographical location features. Moreover, to show appreciation is important. People find motivation from feeling liked and appreciated, and want to feel that their contribution is making a positive impact on other people's lives. Finally, it is important to have clear rules and guidelines for monitoring member’s behavior, otherwise uncertainties and dissatisfaction will occur. / Delande ekonomin, eller gemensam konsumtion, hänvisar till peer-to-peer-delning av varor och tjänster som samordnas genom en kommersialiserad eller samhällsbaserad online-plattform. Plattformar för gemensam konsumtion används för delning av våra underutnyttjade tillgångar, t.ex. våra hem, verktyg och fordon, och kan skapa sociala gemenskaper. Genom att dela använder vi våra resurser mer effektivt och bidrar till en mer hållbar livsstil. Hoffice startades 2013 i Stockholm och främjar gratis arbetsplatser i hemmen, och har fått stor uppmärksamhet runt om i världen. Detta ideella nätverk hjälper människor anordna hemmakontor, där värdar delar deras bostad med människor, som genom Facebook kan reservera en plats för dagen. Syftet är att skapa gratis arbetsytor, med möjligheter för sociala, strukturella och disciplinerade miljöer, samtidigt som individer drar nytta av stöd och intelligens från andra. Denna forsknings syfte är att studera värdarna i Hoffice nätverket, för att hitta sätt att förklara de viktigaste drivkrafterna, liksom hinder, och tillämpa det på en skräddarsydd plattform för att motivera fler människor att vara värd. Den centrala frågeställningen är dessutom, Hur kan välanpassade sociala plattformar öka motivationen för människor att engagera sig i kollaborativ konsumtion som exemplifieras av Hoffice? Sex semistrukturerade intervjuer med tidigare värdar från år 2014-2015 genomfördes för att få kvalitativa svar om hur en plattform online kan utvecklas för att motivera Hoffice medlemmar att bli värdar. Frågorna delades in i tre olika sektioner; Bakgrund, Om Hoffice, och Online-plattform. Observationer utfördes med ett syfte att förstå strukturen hos en Hoffice-arbetsdag, och för att få en bättre förståelse av användarnas behov och beteenden. Efter att en första version av en prototyp tagits fram utfördes utvärderingar och användartester. Resultaten visar att kommunikation, både offline och online, är viktigt när människor engagerar sig i kollaborativ konsumtion, och Facebook har en stor inverkan på människor vid kommunikation och spridning av information. Facebook har dock vissa brister när det gäller att planera och bjuda in folk till evenemang på grund av sina begränsningar och funktioner. När man använder Facebook för en delningstjänst tvingas användarna även ha ett Facebook-konto för att delta. Alla tjänster som innebär att dela bör överväga och stödja geografiska platsfunktioner. Dessutom, att visa uppskattning är viktig. Folk motiveras av känslan från uppskattning, och vill känna att deras bidrag gör en positiv inverkan på andra människors liv eller situation. Slutligen är det viktigt att ha tydliga regler och riktlinjer för övervakning av medlemmars beteenden, annars kommer osäkerhet och missnöje att inträffa.

One important part of the management of zoo populations is the exchange of animals. The removal of an individual can have unknown effects on the social dynamics of the group. Social network studies are a well-established method to describe the social interactions within a group. This study aims to describe the social interactions in a group of chimpanzees and to test how social dominance rank predicts social interaction patters using a social network approach. Data was collected via observations on Kolmarden Wildlife Parks chimpanzee group, which is composed of seven males and eleven females. A total of 50 h of data was collected over 16 days. This resulted in a dominance rank and four different social networks for different behaviors (touch proximity, proximity, affiliative and agonistic behavior). The eigenvector coefficient, with the notable exception of the proximity network, was rarely correlated with the dominance rank and the highest ranked individual was never the most central. The more dominate individuals had fewer links to others through proximity and affiliative interactions. My analysis of the social network structure provides some evidence that the removal of high-ranking individuals would be unlikely to disproportionally affect the structure of the social network in this group. I highlight the possibility of further analysis such as knock-out analysis (where you examine the consequences of the removal of specific individuals) on existing data and argue that more observations would help to draw up a well-structured plan for translocations of individuals in this group. / En viktig del i förvaltningen av djurparkspopulationer är utbytet av djur. Att flytta en individ från en grupp kan ha okända effekter på gruppens sociala dynamik. Studier av djurs sociala nätverk är en väletablerad metod för att beskriva sociala interaktioner inom en grupp av djur. Syftet med denna studie är att beskriva de sociala interaktionerna i en grupp av schimpanser och testa huruvida en ranking av dominans förutspår mönster i dessa sociala interaktioner genom att tillämpa ’social network analysis’ metoden. Observationsdata samlades in på Kolmårdens djurparks schimpansgrupp, som består av sju hanar och elva honor. Totalt samlades 50 timmar av data under 16 dagar. Detta resulterade i en dominansrankning och fyra olika nätverk för olika typer av sociala interaktioner (närhet med beröring, närhet, affiliativa och agnostiska beteenden). Egienvector koefficienten, med det anmärkningsvärda undantaget för närhets nätverket, var sällan korrelerat med dominansrankningen och den högst rankade individen var aldrig mest central. Mer dominanta individer hade färre länkar till andra genom närhet med beröring och affiliativa interaktioner. Mina analyser av de sociala nätverkens struktur ger vissa bevis för att borttagandet av högt rankade individer inte skulle ge oproportionerliga effekter på den sociala strukturen i denna grupp. Jag uppmärksammar också möjligheterna att med mer analyser som t.ex. knock-out analyser (där man undersöker konsekvensen av att ta bort individer från olika nätverk) på befintlig data, samt mer observationer skulle hjälpa för att kunna göra en väl strukturerad plan för flytt av individer från denna grupp.

<p>Similarity in academic achievement among friends (i.e., academic homophily) can arise from two processes, selection and influence. This study applied stochastic actor-based modeling using SIENA to disentangle friendship selection and social influence regarding academic achievement of Chinese adolescents in a three-year longitudinal sample of 880 middle school students (400 girls, year 1 mean age = 13.33) and 525 high school students (284 girls, year 1 mean age = 16.45). SIENA analyses revealed significant selection and influence effects pertaining to academic achievement for both middle school students and high school students across three years. Chinese adolescents preferred friendships with similarly achieving or higher achieving peers but avoided friendships with lower achieving peers. Friends’ influence on academic achievement can be both beneficial and detrimental. Chinese adolescents were more likely to increase in achievement when they befriended high-achieving peers, but decreased achievement when they were friends with low-achieving peers. There were no significant sex differences or school year differences (i.e., the first to second years versus the second to third years) in selection or influence effects for academic achievement. Influence effects were stronger for middle school students than for high school students, but no significant grade level differences emerged for selection effects. This study expands upon prior research by simultaneously assessing selection and influence effects on academic achievement and further examining the direction and strength of selection and influence processes regarding academic achievement using sophisticated modeling analyses. These results provide insights into the important role of cultural context in peer relationships and academic development by considering the strong pressure Chinese adolescents experience to be academically successful.</p>

This study focuses on how applying MCII, a wish-fulfillment and goal-setting method researched by Gabriele Oettingen, benefits the quantity and quality of English language learners' (ELLs) social networks while participating in a study abroad program in the United States. This is done by instructing participants in the use of MCII, giving them weekly reminders on that instruction and the goals they set, and by measuring change from beginning to end. Analyzing the social networks of 36 English language learners at an intensive English program (IEP) after 14 weeks of instruction shows that the ELLs displayed growth in the number of ways they met new people and in the depth of their relationships. This study also shows although learners who used MCII largely perceived it positively and noted using it in their lives, there was no significant difference between that group and those who did not use MCII in terms of proficiency development.

More than half a billion people use Online Social Network Sites (OSNS) today. They disclose personally identifiable information such as names, date of birth, email address, phone numbers, and home address on their profiles. Some OSNS users also disclose their political and religious views and personal interests. The huge commercial potential of OSNS users’ information and the integration of OSNS with third party advertisers and/or aggregators pose threats to users’ privacy. This thesis reports a study which contributes to our understanding of the form and nature of online privacy by critically analysing the privacy concerns related with the failed launch of Facebook’s advertising tool Beacon. Beacon is an interesting case study because it highlighted the privacy concerns of OSNS users. Qualitative data was gathered from 29 weblogs (blogs) representing user opinions (492 comments) published between 6th November 2007(when Beacon was launched) and 28th February 2008 (when commentary had dwindled). A thematic analysis of the blogs contributed in the development of a taxonomy of privacy concerns of OSNS users specifically related with the third party information use. Noticeably, the concerns such as commercialism, terms of service (TOS), lack of user control, lack of user awareness and data protection influence user perceptions of online privacy. The limitations and key implications for designers and service providers of OSNS are also discussed.

Idag lever vi i ett samhälle som drabbats av en ensamhetsepidemi där de värst drabbade är äldre människor över 60 år. Ensamheten påverkar oss människor mentalt och fysiskt, vilket kan vara en faktor som leder till en mer fortgående mental åldringsprocess men även en tidigare bortgång. Detta arbete syftar till att utforska hur en användarcentrerad designprocess kan bidra till att öka sociala nätverk hos äldre. Studien bygger på litteratursökning, kvalitativa intervjuer och observationer med äldre över 65 år. För att avgöra vem som känner sig ensam gjordes en `UCLA Loneliness Scale´ som vanligtvis används i forskningssyfte för att mäta ensamhet. Designarbetet består av en förstudie (intervju, observation och autoetnografi) och designprocess som innefattar kravspecifikation och idegenerering. Arbetet resulterade i ett produktförslag i form av en brosch som bärs av användaren. Tanken är att den ska ge en känsla av tillhörighet vilket kommer minska känslan av ensamhet eller till och med förhindra förekomsten av ensamhet hos användaren. Produkten är avsedd för kommande generationer och utesluter inte digital utveckling. / Today we live in a society affected by an epidemic of loneliness where the worstaffected are  older people over 60 years. Loneliness affects us people mentally and physically, which can be a factor that leads to a more progressive mental aging process but also earlier death. This work aims to explore how a user-centered design process can contribute to incease social networking amongst elderly people. Research strategy involves literature search, qualitative interviews and observations with elderly over 65 years. Design work consists of survey methods (interview and observation) and design process, which includes requirements specification and idea generation. To determine who feels lonelly, a ´UCLA Loneliness Scale´ was made, which is commonly used in research studies to measure loneliness. Design work consists of research methods (interview, observation and autoetnography) and design process, which includes requirements specification and ide generation. The work results in a product proposal in the form of a badge that is used as an accessory. This would give the user a sense of belonging and reduce the feeling of loneliness or prevent the feeling of loneliness. The product is intended for future generations and does not exclude digital development.
