Our purpose was to research the new reform amendment" Lag om etableringsinsatser för vissa nyanlända invandrare", and whether the establishment of the reform is good and if it was a necessary amendment. For that reason, we have chosen to answer our purpose in these issues with this question formulation; how can the change of the law establishing operations influence the newcomers in the labour market, the problems the law intends to address, how the new change in the law is different from when the municipality "kommun" was responsible, and how the law can be discussed based on theories of social capital and weak ties. The method used in this study is from a adductive approach where the research is based on both empirical evidence and existing theory that interact between these two. The results that emerged in our work was that the newcomers within the labour market has been remote, the way the municipality’s addressed the problem did not work and the result of this was a new reform amendment, where a new participant established. The previous research has shown that there was a variation to how different the municipality managed the establishment of the new arrivals. According to the government the municipality failed in the matter of establishing new arrivals. Further investigation has also shown that the social network has been central point in the establishment of the arrivals.

The object of this master’s dissertation has been to investigate one-person enterprisers’ (OPE) experiences of conducting both personal identity and brand at social network sites (SNS). The purposes of this research have been to elaborate on sociological theories of brand and identity in a network society context and to present hypotheses on how SNS can be developed to empower all OPEs. Since this field is rather unexplored in sociological research, and because it is the experiences of the OPEs that are the focus of the research, ethnographic methods, i.e. qualitative interviews, were chosen. These interviews were then analysed, primarily through Erving Goffman’s theory of self-presentation, Manuel Castells’s theory of identity, and the sociological concept of life-conduct deriving from Max Weber. The findings provoked both theoretical and empirical conclusions. The theoretical hypothesis is that Castells’s and Goffman’s respective theories should be used as back and front end interpretations of everyday life conduct. The empiric hypothesis provoked is that some OPEs have a strategic (as opposed to a sincere) approach to SNS. These OPEs are experiencing alienation and anomie. To manage this, SNS need to focus more on tools for social communication and less on methods for making SNS ends in and of themselves.

Social network site (SNS) has been very popular with global Internet users since 2008, the amount of social network users grew very much. Based on some reasons, users enjoyed using social network site. However, whether the current users or new users will continue to use social network site or not is an issue today. To assure social network site¡¦s company could develop and run well in the future, we must realize the factors that can increase and retain the user to use. This study based on expectation confirmation theory (ECT) and through literature review to explore the factors that can influence the user¡¦s satisfaction. Successfully, we integrated perceived utilitarian benefit and perceived hedonic benefit into original ECT model. In this study, an empirical survey methodology with eight hypotheses was applied to verify this model. Covariance-based structural equation model (SEM) was used to analyze data and evaluate the model. The results pointed out that past ECT model with only one aspect can be extended from utilitarian and hedonic dimensions. It indicated that confirmation of utilitarian benefit, perceived utilitarian and hedonic benefits have significant influence on user¡¦s satisfaction. Lastly, user¡¦s satisfaction will positively influence the continuance intention. In sum, this study integrated utilitarian and hedonic dimensions into original ECT model, and proposed a more comprehensive framework to explain the continuance usage of social network site. This study also provided a reference model for future continuance intention research and some suggestions for social network site practitioners.

As the number of users grows, more and more companies and brands use Facebook to shape their own images. What they want is ¡§Word of Mouth (WOM). However, each user has his/her own characteristics, and it might affect the WOM activities on Facebook. This research try to (1) explore the traits of WOM on Facebook, (2) find users¡¦ motivations of WOM behaviors on Facebook, (3) figure out what kind of characteristics might influence the WOM activities on Facebook, and (4) find some situational factors that have impacts on WOM activities on Facebook. The results show that (1) users who have high needs of uniqueness likes to share WOM to out-group members, (2) users prefer to share non-business messages and the messages which are related to their own benefits, (3) users with different characteristics have different motivations of WOM activities on Facebook. Keywords: Word of Mouth, Facebook, Characteristics, Situational Factors, Focus-group Interview, On-line Survey, social network site.

Nowadays, the rapid development of New Technologies of Information such as internet has a tremendous impact on people's life and environment. People now are not only using Blog and social network as a mean to share their life, but also they are using this platform to divulge and promote their diaries, articles, and life experiences. Fashion Guide, the most famous website in Taiwan, combining Blogs, social websites ,discussions forums is an eloquent example. This research is trying to find out whether Fashion Guide website has an influence on Taiwanese female purchasing behavior of cosmetics. This empirical evidence underscoring the impacts of websites such as Fashion Guide on females purchasing decision has the following outcomes: 1-Fashion Guide¡¦s members are over 80 percent and are mostly living in north of Taiwan, most of them are working for IT industries and their age range from 26 to 30 years old.2-The motivation of using the website lies on the fact that they are avoiding risks, above all the risk of getting the products they do not like.3-The members of Fashion guide find the discussion forums more trustworthy than social networks and Blogs.4-Most of members believe that Fashion Guide¡¦s website contents are more reliable than television commercials and suppliers cosmetics websites, therefore in the future marketing can make use of forums, social networks and blogs as a non-negligeable broadcasting platform.

Enterprises spread messages usingcomputer networks has become a trend due to popularity of the Internet. It is important for enterprises to select appropriate network media to achieve high effectiveness. It¡¦s even more important for Internet marketing companies to deploy marketing strategies given all possible media selections. The network media is progressing with new technical applications, such as email, blog, micro-blog and social network, etc. Each has its own development background and can achieve different effectiveness. The study of this thesis is to explore the differences of spread rates, diffusion time distribution etc. by spreading the same network messages with different network media (such as Email, social network, Facebook etc.). It will help enterprises to understandthe characteristics and effectiveness of each network medium. As a result, enterprisescan learn how to choose the right media to get the best message diffusion result. The study shows that various message carriers willexhibit different effectivenessdue to the nature of message contents. For example, commercial messages can be best delivered with Facebook while messages of special interests can be effectively delivered by email. Regardless what medium is chosen, two common phenomena can be observed: high click rate within the first 24 hours, and the low click rate in midnight.Enterprises will do a good spread messages plan using computer networks in known the two common phenomena.

This study examines the effects of social tie strength, value fit and affect-based trust of overseas workers on their cultural knowledge acquisition in foreign countries. Based on the assumption that cultural knowledge is acquired through social interactions, the research model encompassed 3 social-related independent variables and tested empirically from 536 interpersonal relationships reported by 136 respondents. The results revealed that social tie strength and value fit have positive impacts on cultural knowledge acquisition not only directly but also indirectly, through the mediation role of affect-based trust. However, the mediation effect differs between relationships with local nationals and relationships with non-local nationals. Specifically, affect-based t rust is essential for the effect of social tie strength to local nationals instead of that to non-local nationals; moreover, the mediation effect is sufficient on value fitted non-local nationals but is incomplete on value fitted local nationals. The implications of the findings and the need for future research were also discussed.

This dissertation considers graph theoretic generalizations of the maximum clique problem. Models that were originally proposed in social network analysis literature, are investigated from a mathematical programming perspective for the first time. A social network is usually represented by a graph, and cliques were the first models of "tightly knit groups" in social networks, referred to as cohesive subgroups. Cliques are idealized models and their overly restrictive nature motivated the development of clique relaxations that relax different aspects of a clique. Identifying large cohesive subgroups in social networks has traditionally been used in criminal network analysis to study organized crimes such as terrorism, narcotics and money laundering. More recent applications are in clustering and data mining wireless networks, biological networks as well as graph models of databases and the internet. This research has the potential to impact homeland security, bioinformatics, internet research and telecommunication industry among others. The focus of this dissertation is a degree-based relaxation called k-plex. A distance-based relaxation called k-clique and a diameter-based relaxation called k-club are also investigated in this dissertation. We present the first systematic study of the complexity aspects of these problems and application of mathematical programming techniques in solving them. Graph theoretic properties of the models are identified and used in the development of theory and algorithms. Optimization problems associated with the three models are formulated as binary integer programs and the properties of the associated polytopes are investigated. Facets and valid inequalities are identified based on combinatorial arguments. A branch-and-cut framework is designed and implemented to solve the optimization problems exactly. Specialized preprocessing techniques are developed that, in conjunction with the branch-and-cut algorithm, optimally solve the problems on real-life power law graphs, which is a general class of graphs that include social and biological networks. Computational experiments are performed to study the effectiveness of the proposed solution procedures on benchmark instances and real-life instances. The relationship of these models to the classical maximum clique problem is studied, leading to several interesting observations including a new compact integer programming formulation. We also prove new continuous non-linear formulations for the classical maximum independent set problem which maximize continuous functions over the unit hypercube, and characterize its local and global maxima. Finally, clustering and network design extensions of the clique relaxation models are explored.

This thesis begins with the economic globalization, and uses secondary data analysis to explore the labor structural change and employment conditions in Taiwan under globalization. Then, using the social exclusion theory, through qualitative in-depth interview methods, this study explores the unemployment and re-employment experiences of the long-term unemployed and the marginally employed, as well as the economic, psychological, and social network exclusion in the process of employment to unemployment. This study also discusses the roles of government employment policies, familial and social relationship networks. Finally, policy suggestions are proposed according to related research discoveries. The study finds that: first, in terms of unemployment and re-employment experience, most laborers regard unemployment with a passive and external attribution attitude; this negatively influences emotions, interpersonal relationships, and later re-employment. While unable to return to the original career, unemployed laborers develop different life choices. Those who return to the labor market the earliest return because they succumb to economic pressure, becoming marginal workers who are willing to do any work, and the other kind are those who are continuously accumulate capital and convert it into employment resource; these are the active workers. On the other hand, there are two types of people who remain unemployed. One is the type that becomes waiting unemployed because they are unwilling to budge on employment conditions, and the other is the type that is limited by their own employment abilities and become helplessly unemployed. Additionally, unemployed people with different identities also have different life choices at their inability to return to their original careers. Secondly, from labor market exclusion to social exclusion: 1.Labor market exclusion and economic exclusion: unemployment results in decreased income, which further impairs daily living needs, basic medical care, and educational services, as well as stops one from participating in entertainment and leisure activities; these impact basic life opportunities and makes one feel more and more exclusion. 2. Labor market exclusion and psychological exclusion: emotional changes during unemployment are primarily affected by decreased income, but it is also affected by personal expectations of future re-employment. For the involuntarily unemployed, they feel a greater sense of lack of control and impotence over their lives. 3. Labor market exclusion and social relationship exclusion: as a result of lack of self esteem or economic considerations, the unemployed have significantly less social interaction, in a singularized network structure, which would provide relatively smaller economic or re-employment support. 4. Social networks have a positive influence on alleviating the multifaceted exclusion caused by unemployment, but the majority of unemployment laborers have significantly insufficient social network functions. Those who are unemployed with weak formal and informal social networks would fall into social exclusion, have a bleak outlook on the future and believe that there is no chance to extricate oneself from the various unfavorable situations caused by unemployment. ¡@¡@The end of the thesis also discusses some related issues, such as the unemployment issue (unemployment conceptualization? Who are the unemployed? Work or retire?), social exclusion issues (applicability of social exclusion theories? what is the role of the country in labor market exclusion? Does the employment policy cause social cohesion or social exclusion?), social structures, and individual action interactions. Finally, from labor market intervention, construction to social network, and proposes related policy suggestions to reverse social exclusion.

The invention of Internet affects human life style and also creates many innovations and applications of business models. Social Network Service, SNS, is an innovative application and business model in recently years. It changes the development and communication of current social network and gathers high-traffic viewers to create more business opportunities. However, what¡¦s value attracted users to use SNS. This study focuses the usages of SNS from the users of Taiwan area by empirical research. From the customer point of view, satisfaction and word-of-mouth could be relative to and affected by utilitarian value and hedonic value. Therefore, this study builds an applicable integrated model and uses Structural Equation Modeling, SEM, to analyze and approve the relations of constructs. The following is the conclusions of this study. (1) The theory of this study confirms fit indices in SEM, and cause and effect of each construct is very obvious to support it. (2) Utilitarian value can be measured by factors of sociality, convenience, and information availability; hedonic value can be measured by factors of adventure, escapism, and affiliation. (3) Utilitarian value and hedonic value affect customer satisfaction; customer satisfaction affects word-of-mouth. (4) Utilitarian value and hedonic value positively affect word-of-mouth, but providing a good customer satisfaction can enhance word-of-mouth. (5) Influence of hedonic value is higher than that of utilitarian value relative to customer satisfaction and word-of-mouth. It shows that the users prefer hedonic value in SNS. Therefore, this study can be the reference of business administration and academic research.
