Overconfidence and its relationship to investor market participation is well established in the finance literature. The research into investors and social networks is only in its infancy, however. This thesis extends the literature by expanding on both subjects individually, then bringing them together. Empirical work on individual investors in the existing literature links overconfidence and excess trading, resulting in impaired returns. The preferred activity metric, monthly account turnover, encapsulates two separate elements, though. One is trade frequency. The other is leverage use. Chapter 4 of this thesis theorizes based on the existing literature that in fact trade frequency is not a good measure of overconfidence. It then demonstrates through empirical analysis of a group of individual non-professional foreign exchange traders that leverage is much more suitable to that role. Chapter 5 turns the focus to social networks, particularly with respect to information transfer. The literature in finance anticipates that network members benefit from their membership. Further, network position (social capital) enhances that benefit. This thesis challenges that expectation with respect to non-professional investors. Findings based on analysis of members of an online retail foreign exchange trader social network indicate that while there may be an educational benefit accruing to unsophisticated members, for more sophisticated ones membership appears to have a negative effect on returns. One potential explanation for the negative impact of network membership is explored in Chapter 6 in the form of impression management. It is hypothesized that sophisticated investors are influenced in their behaviour by the realization they are being observed, and also the size of their audience. Analysis of foreign exchange traders indicates an increase in leverage use among sophisticated investors as their audience size increases, coinciding with a decline in trade excess returns, making the case for an observation-based rise in overconfidence.

Companies may need an infusion of capital for a multifold of reasons. The importance of capital needed for innovation applies not only to large companies but also to start-ups. In recent years crowdfunding has evolved and become a common alternative for entrepreneurs to finance their start-up. Research about crowdfunding is still in its infancy, and few articles about crowdfunding has yet been published. The purpose of this paper is to examine how social media influences crowdfunding as a communication and marketing channel. The paper is based on a quantitative research strategy, with data regarding 156 campaigns, featured on Kickstarter.com. The outcome of this paper shows that many campaigns used social media to market the campaign. On the contrary not all campaigns used all examined social media. Some social media were more commonly used than other, such as Facebook or Twitter. The outcome of the paper however shows that the number of updates made on the campaigns site does not have any connection regarding the funding level. It can furthermore be other factors that play a crucial role whether or not a campaign reaches its funding goal.

This dissertation uses a relational approach and a contentious politics framework to examine the archaeological record. Methodologically, it merges spatial and social network analyses to promote a geosocial archaeology. Combined, the articles create a counter-narrative that highlights how environmentally focused investigations fail to explain how and why societies in the Southwest often reorganize horizontally. The first article uses geosocial networks, which I argue represent memory maps, to reveal that the socially important, and sophisticated, act of forgetting was employed by people in the Gallina region during A.D. 1100 - 1300. A concomitant community level, settlement pattern analysis demonstrates similarities between the arrangement of Gallina and Basketmaker-era settlements. These historically situated settlement structures, combined with acts of forgetting, were used by Gallina region residents to institute and maintain a horizontally organized social movement that was likely aimed at rejecting the hierarchical social atmosphere in the Four Corners region. The second article proposes that as ideologically charged material goods are consumed, fissures within past ideological landscapes are revealed and that these fissures can demonstrate acts of resistance in the archaeological past. It also contends that social and environmental variables need to be combined for these conflicting religious and political practices to be correctly interpreted. The third article applies many of the ideas outlined in the second article to a case study in the Greater Southwest during A.D. 1200 - 1450. Fractures in the ideological landscape demonstrate that the Salado Phenomenon was a religious social movement formed around, and successful because of, its populist nature. Based on variations in how the Salado ideology interacted with contemporaneous hierarchical and non-hierarchical religious and political organizations it is probable that the Salado social movement formed around desires for the open access to religious knowledge.

Due to the increased number of the amount of asylum-seekers that have migrated to Sweden lately, the topic has received increased attention. This has contributed to housing shortage and policy reforms for new migrants to arise in order to ensure that everybody gets housing. Asylum seekers often experience more difficult patterns to housing, and for LGBT asylum seekers especially since they are such a marginalised group in our society already. Housing is an important part in the initial settlement stage and good housing enables successful resettlement and that will help with the integration process. The aim of this thesis is to look at LGBT asylum seekers mobility and what constrains and opportunities they face in that process. To answer these questions qualitative method and semi-structured life story interviews have been performed with twelve LGBT asylum seekers. The result of these interviews has been presented around four different concepts that were factors contributing to their mobility. These four concepts that were found in the interviews was forced migration, homophobia, social network and freedom. These findings should be of interest for further studies in order for LGBT asylum seekers mobility patters to become more safe and secure.

Job seekers and employers frequently make application and selection decisions based on how well they believe there is a ‘fit’ with the organization and job. The personenvironment fit literature has strongly supported this practice demonstrating that fit is an antecedent to attraction, selection, and attrition. What has been lacking, however, is evidence that once individuals enter the organization their fit relates to performance. Using a social network analytical lens, I develop a framework that integrates PE fit and social networks to explore antecedents to employee performance. Using this framework, I explore how informal workplace relationships may act as catalysts through which fit either enhances or detracts from individual performance, how fit might directly influence performance once the social context is taken into account, and how fit might make an individual an attractive exchange partner benefiting performance. Results suggest that PE fit is related to individual performance (both in- and extra-role) but that this relationship differs depending on how well embedded the employee is in the informal social networks of the organization. It is only when accounting for the ‘who you know’ element of organizational life that we can see how ‘who you are’ relates to performance.

Resource mobilization theory and political opportunity theory are often used to describe separate portions of social movements. This dissertation proposes a combined model of these two theoretical perspectives which describes how social movement organizations effectively engage in social marketing both online and offline. The field of social marketing highlights the utility of standard commercial marketing practices to achieve non-commercial goals. I argue that, while commercial marketing practices may benefit social movement organizations and are more cost effective given emerging technology, momentum for gathering resources, will be stifled unless a political opportunity presents itself. Guided by theory about the ways that political opportunities are translated into action by organizations, and momentum acquired through mobilizing resources, cycles of opportunity and resulting resource responses by housing social movement organizations are examined over time to present a case study for this theoretical model. The seemingly endless cycle of resource gathering underscores organizational mobilization of resources as a process rather than an outcome. My model outlines numerous forces that shape an organization’s ability to mobilize in two distinct ways, through resources deployed (online and offline) and resources gathered. Resources will be discussed in three categories: organizational characteristics, network structure/position, and media/Internet presence. The relative importance of these factors and this process are described at length in the review of theoretical literature and will be illustrated in the case study that I provide: the housing social movement. Data for this case study has been collected through hyperlink network analysis, general webometrics, and congressional archives. My research aims to provide suggestions for the strategic socio-technical networking and social marketing of social movement organizations.

My dissertation examines how individuals respond to workplace social comparisons. I measure the explicit set of referent others that individuals compare themselves against in order to evaluate their own level of performance. I examine how the social context of these comparisons impact discretionary performance related behaviors by examining how an individual’s position within a social network and the structural characteristics of an individual’s reference group influences the experience of discrete emotions. Specifically, I examine how malicious envy and benign envy mediate the relationship between social comparison and workplace behavior in a field setting. Results indicate that social network structure plays a significant role in motivating both productive and counterproductive responses to social comparison. Whether or not an employee responds to upward social comparisons by increasing their own work effort or engaging in deviant behavior is influenced by the experience of benign and malicious envy, which is in turn influencedby the network structure of reference groups. Furthermore, social network position plays a moderating role in the occurrence of workplace deviance by either enhancing or limiting the opportunities an employee has to engage in deviant behavior.

This paper provides insights on how five different frames of the Edward Snowden issue (Hero, Patriot, Traitor, Whistleblower, Dissident) have been diffused on the Twitter platform. This study uses NodeXL to collect, analyze and visualize all the tweets including the keyword “Edward Snowden” from February 17 to April 10, 2014 to examine the flow of information and the interaction between opinion leaders along with the characteristics of opinion leaders in this specific issue. Findings provide insight about future strategic communication for general branding and public image maintenance. / text

Given the increasing number of younger immigrants from China, we have noticed diversified performances of Chinese-American teenagers based on the age they come to the U.S. This thesis thus examines three specific aspects—assimilation, social network site (SNS) use, and reaction to Asian stereotype—of Chinese-American teenagers living in Austin, regarding intraethnic differences between and among different clusters of this cohort as the second generation immigrant. By employing semi-structured interviews conducted with teenagers who have respective immigrant history and family background, a wide array of patterns about assimilation, SNS use, and reaction to Asian stereotype are traced and analyzed alongside demonstrating outlines and traits in terms of different generation clusters (1.25ers, 1.5ers, 1.75ers and 2.0ers). A total of ten Chinese-American teenagers, aged from 15 to 18, are recruited and interviewed through snowball approach, allowing for the surface of intraethnic variations on the aforementioned aspects. Preliminary discussions are made to tease out how these three aspects are intertwined. / text

<p>Abstract</p><p>As online social network services are becoming one of the dominant media channels the importance of disseminating messages through them is of high importance for governments, organizations, companies etc. The online social network services are several and changes rapidly as they grow and evolve. Being networks, the services give the user the tools to send, as well as receive text and information. This proposes us with yet another obstacle in communication via online social network services since sender and receiver merges together.</p><p>Online social network services and the Blogosphere, which essentially also is a network, exist in the context of Web 2.0. The crucial feature of Web 2.0 is to a large degree the harnessing of collective intelligence i.e. the collection of individual knowledge and information. Many of the tools and sites within Web 2.0 are therefore of a network structure, hence further stressing the importance to communicate via networks in general.</p><p>Network Analysis is the discipline through which we can see and understand the larger patterns of networks. In this thesis I have looked into three key concepts of Network Analysis; Weak Links, Growth and Preferential Attachment. I have found that we can use the knowledge of Network Analysis to disseminate messages via online social network services since it provides us with the raw structures of how networks tend to grow, and how messages tend to disseminate.</p><p>Title: Web 2.0 and Network Society – PR and Communication: The Challenge of Online Social Networks</p><p>Number of pages: 34</p><p>Author: Max Tandefelt</p><p>Tutor: Else Nygren</p><p>Course: Media and Communication Studies C</p><p>Period: HT 07</p><p>University: Division of Media and Communication, Department of Information Science, Uppsala University.</p><p>Purpose/Aim: Facilitate message dissemination through online social network services, as they are becoming one of the dominant media channels</p><p>Material/Method: Network Analysis</p><p>Main results: I have presented crucial concepts of Network Analysis that can be used for message dissemination via online social network services</p><p>Keywords: Online Social Network Services, Network Analysis, Web 2.0, Message Dissemination</p>
