The purpose of this study was to increase knowledge about what the lives of the unemployed youth of immigrant background looks like, and what the views of the unemployed young people are about work and employment. The study is a qualitative study where the empirical material is based on interviews with seven unemployed immigrant youth between the ages of 19 and 25 years. A study where the central questions was to explore how the informants' living conditions and identity are affected by being unemployed. The other issues aimed at how informants background affected their ability to enter the labour market, and the job expectations the informants had about the future and the Swedish labour market. Empirin have been analyzed with regard to methodology tool based theory, as well as theoretical starting points, such as social capital, formal and informal channels, ethnicity and stigma theory. The result is shown in five different disciplines on the basis of informants experiences of the situation they are in. These topics are The unemployment and welfare, The social network's importance, The foreign name the obstacles, The road to the labour market and finally, The social environment. The results show that informants welfare was affected in a destructive way when informants experienced a lack of employment. Informants perceived that the social network's importance was very prominent in the labour market, which proved, however, that informants social networks were very limited and without a resource for them. The result also shows that the majority of informants had been discriminated against by employers. A crucial factor for this form of discrimination were informants background and the foreign name. Road to the labour market was perceived stressful when the economic situation in the country was unstable and in decline. The results suggest that the informants had to lower their job expectations when they could not change the situation. Moreover, it appeared to indicate that ambient performances that immigrant segregated areas are perceived as socially vulnerable, both as a social problem for society. Informants self-image was negatively affected by the social environment perceptions of immigrants segregated neighbourhoods, which were seen by informants as a contributing factor that made their job opportunities more difficult.

隨著個人電腦與網際網路科技的逐漸成熟，網路上每日都有巨量資料（Big Data）產生。近年來隨著社群網站的崛起，如何處理這些巨量的社群資料，並有效率地提供出有意義的社群資訊，將是這幾年社群網路領域研究的重點。每當內閣改組消息一出的時候，各政府部門單位的官職繼任官員，都會成為社會公眾關注的議題。本研究將使用中華民國政府官職資料庫，以社群網路分析與連結預測理論為基礎，並透過資料庫中所提供的資料，隨著不同評選時間點以及評選官職建置出網路。擷取網路的資訊，利用本文所提出的多面向模型（Multiperspective Model）產生多種觀點的分數。接著使用評選模型（Evaluation Model）將各個觀點的分數整合，進行某官員繼任某官職可能性計算，然後輸出官職繼任官員的評選清單（Evaluation List）。最後對輸出的評選清單分別對空降繼任狀況、各級上司對於繼任人選決定影響力、單一觀點與多觀點評選方式的評選結果、多觀點評選方式下重視的觀點，以及官職繼任成因五項分析進行探討。 / With the well development of personal PC and the Internet technology, there is a huge amount of data (Big Data) being generated on the Internet every day. Because of the debut and rise of social websites, how to deal with such a huge amount of community information as well as efficiently provide meaningful data to the public has been an explored main issue in the field of social network research in recent years. When the news about cabinet changing was released, the successor of various government departments will become the actively concerned topic for the public. This research applied a government position transaction database as the elements to build the network, which based on Social Network Analysis and Link Prediction theory with different evaluation position and evaluation time. Captured information in the network was used to generate the scores of multiple perspectives according to the Multiperspective Model. Then using the Evaluation Model, which can integrate each observed perspective, and calculate the probability of an official succeeds of a position. Finally the network could output the evaluation list of position successor. In the end, the outcome of the evaluation list was applied to analyze and discuss the following 5 research questions: The situation that the successor isn’t from the unit of successive position, the influence of all levels superiors on the succession decision, result of evaluative methods of a single view and multiple perspective, the important perspective of Multiperspective evaluation, and causal relationship of official successor.

The World Wide Web has become a medium for people to share information. People use Web-based collaborative tools such as question answering (QA) portals, blogs/forums, email and instant messaging to acquire information and to form online-based communities. In an online QA portal, a user asks a question and other users can provide answers based on their knowledge, with the question usually being answered by many users. It can become overwhelming and/or time/resource consuming for a user to read all of the answers provided for a given question. Thus, there exists a need for a mechanism to rank the provided answers so users can focus on only reading good quality answers. The majority of online QA systems use user feedback to rank users’ answers and the user who asked the question can decide on the best answer. Other users who didn’t participate in answering the question can also vote to determine the best answer. However, ranking the best answer via this collaborative method is time consuming and requires an ongoing continuous involvement of users to provide the needed feedback. The objective of this research is to discover a way to recommend the best answer as part of a ranked list of answers for a posted question automatically, without the need for user feedback. The proposed approach combines both a non-content-based reputation method and a content-based method to solve the problem of recommending the best answer to the user who posted the question. The non-content method assigns a score to each user which reflects the users’ reputation level in using the QA portal system. Each user is assigned two types of non-content-based reputations cores: a local reputation score and a global reputation score. The local reputation score plays an important role in deciding the reputation level of a user for the category in which the question is asked. The global reputation score indicates the prestige of a user across all of the categories in the QA system. Due to the possibility of user cheating, such as awarding the best answer to a friend regardless of the answer quality, a content-based method for determining the quality of a given answer is proposed, alongside the non-content-based reputation method. Answers for a question from different users are compared with an ideal (or expert) answer using traditional Information Retrieval and Natural Language Processing techniques. Each answer provided for a question is assigned a content score according to how well it matched the ideal answer. To evaluate the performance of the proposed methods, each recommended best answer is compared with the best answer determined by one of the most popular link analysis methods, Hyperlink-Induced Topic Search (HITS). The proposed methods are able to yield high accuracy, as shown by correlation scores: Kendall correlation and Spearman correlation. The reputation method outperforms the HITS method in terms of recommending the best answer. The inclusion of the reputation score with the content score improves the overall performance, which is measured through the use of Top-n match scores.

The subjects such as the internet evolution and the own interactive social networks (especially Twitter, Facebook and YouTube), the fast technological changes that happens in the digital environment and the communication agencies role in the virtual market were considered. In this sense, it was possible to observe the social network importance, nowadays, in the organization business. The lack of academic material about this theme turns the visits and data collection at websites into a valuable complementary resource. In addition, with the focus on the Brazilian scenario, semistructured qualitative interviews were made with 11 companies managers and three advertising agencies managers. This allows us to gather the motivations for the use of the social networks by the companies, as well as to collect other valuable information for this study. The theoretical framework persues to contextualize a prime outlook for this investigation, considering the internet dynamic environment, the interactive social networks and its value, the mobile access, and the advertising agencies and the social networks. Besides the results presented on this study, the field discoveries and its discussions fostered the creation of the social maturity degree table in terms of the moment that the organization is facing in the digital context, as well as the development of the organizational learning in the virtual environment for social networks model. Finally, the conclusions were presented, as well as the final considerations. This study has shown the social networks importance in the daily use of the companies and the need to be present in the virtual environment, once they are already there, even in a passive manner. Although there was no generic element that could be used as a motivational pattern for the initial investment in the social networks, the branding in this media, followed by the need to establish a relationship channel stood out as the most relevant motivating factors. / Esse estudo objetiva compreender porque as empresas, no Brasil, decidem investir em redes sociais na internet. Foram considerados fatores como a evolução da internet e das próprias redes sociais interativas (em especial Twitter, Facebook e YouTube), as rápidas mudanças tecnológicas que ocorrem no ambiente digital e o papel das agências de comunicação no mercado virtual. Nesse contexto, foi possível observar a importância das redes sociais, atualmente, no negócio das empresas. A falta de material acadêmico sobre o assunto fez com que a visita e a coleta de materiais em diversos websites fossem um recurso complementar valioso. Adicionalmente, com o foco no cenário brasileiro, foram realizadas entrevistas qualitativas semiestruturadas, com 11 gestores de empresas e três gestores de agências de comunicação, o que propiciou um mapeamento das motivações para a utilização das redes sociais pelas empresas, assim como o levantamento de outras informações valiosas para esse trabalho. O referencial teórico buscou contextualizar um panorama privilegiado nesse estudo, considerando o ambiente dinâmico da internet, as redes sociais interativas e seu valor, a mobilidade de acesso, e as agências de publicidade e redes sociais. Além dos resultados apresentados nesse estudo, as revelações de campo e suas discussões propiciaram a elaboração de uma tabela de grau de maturidade social em relação ao momento em que as empresas estão no âmbito digital, assim como o desenvolvimento de um modelo de aprendizagem organizacional no ambiente virtual para redes sociais. Finalmente, foram apresentadas as conclusões, assim como as considerações finais. O estudo demonstrou a importância das redes sociais no cotidiano das empresas e a necessidade de estarem presentes no ambiente virtual, já que estão nesse universo mesmo que de maneira passiva. Embora não tenha havido um fator genérico que possa ser utilizado como padrão motivacional para o investimento inicial nas redes sociais, a visibilidade da exposição da marca nesse meio, seguida pela necessidade de criar um canal de relacionamento com o cliente destacaram-se como fatores motivacionais mais relevantes para esse movimento.

This work reviews the current literature and application methods of strategic KPI frameworks, KPI definition and measurement, target setting and benchmarking for social networks based on journals, books and whitepapers while including an interview with a social media agency. In a second step, the acquired knowledge is applied on a case study for a salon haircare company. The conclusions are based on in-company experts in the field, external social media agencies and an internal survey. Based on a behavioral survey, the requirements and gaps in the organization are identified. This leads to the application of a theoretical framework on the case company and a suitable definition of KPIs. The final delivery includes an analytical tool measuring all KPIs. Finally, all KPIs are related to targets and benchmarks from industry, social network sites, competitors and historical data. The final results are easily transferrable to other players in the industry.

The diploma thesis is focused on the social networking sites in terms of their use for increasing the competitiveness of companies. The first part deals with a theoretical introduction to social networks where the basic concepts are defined and then characterized by major networks globally. Each social network is analyzed both in terms of the structure of its users, and are listed as individual options, which provides for promotion within their system - they are mentioned both paid and unpaid opportunities. At the end of this section are described the general possibilities of using social networking for business - ways to measure the impact of these activities, risks and requirements of their operation within the company. The second part is a practical solution to use social networks to support the selected e-commerce business. The introduction provides basic parameters of the e-shop is defined by the competitive environment. The analysis carried out various solutions to various social networks. It is designed and implemented their own social network to the target audience the company. The practical part ends with a final report including recommendations for further progress in the use of social networks. The main contribution of the paper is to present a detailed analysis of selected enterprise communication on social networks, including putting all the relevant data from which the conclusion can be drawn in specific recommendations to further enhance competitiveness.

Thesis describes social networks as a new tool, which affects the way how people use in-ternet and how they communicate. This relatively new technology and trend is firstly de-scribed from technological perspective, which is in harmony with Green ICT. In detail describes contributions of virtualization, cloud computing and Web 2.0 which allowed this innovation in a first place. On the other side it describes social networks from sociological perspective as simple adapting to natural development, which doesn't require any big be-havioral changes. It seems that it is just another step in development of tools for infor-mation exchange and communication. Secondly thesis separates enterprise social network and characterize their potential application inside the company for supporting operation, communication, documents and information sharing, managing or decision making. Thesis analyze and compare current available enterprise social networks and creates multi-criteria matrix, which provides manual or guide for choosing the right ESN tool according to company's preferences. Simultaneously based on sample activities and dealing various situations from project management, compares communication by using enterprise social network with communication via email. On this examples demonstrate added value by using enterprise social networks by knowledge workers in the meaning of more effective cooperation and higher employee satisfaction.

Several studies shows that the dominant norms of masculinity are a hinder for boys to perform in school and a hinder for men to choose female-dominated occupations. Moreover, selecting a career can be a complex decision for young adult men´s to choose a female-dominated higher education - and this dilemma has been a topic of much reports and research. However, there is still a lack of understanding regarding the influence of social capital on young people as they transition to higher education. Not many studies have been made on the male student´s experience of the impact of social capital on their gender-breaking higher education choices.Therefore the aim of this study is to understand which social capital and social network relations are of importance to young male students´ gender-breaking higher education choices. Furthermore, this study aims to examine the conditions that have broadened the informants' motive to choose a higher education.A qualitative method with semi-structured interviews was used to answer the purpose of this essay and the method of choice for analysis were social networks analysis of ego-net, which is a method on studying social relations. The result is being analyzed by using a conceptional model based on Lent el. al (1994) Social Cognitive Careers Theory, Pierre Bourdieu’s (1986) Theory of social capital and Ego-net (Crossley et. al 2015).The results of this study show that social background and gender have a limited significance in relation to the informants' gender-breaking choice of higher education and career path. There are various motives that have encouraged and motivated the informants' gender-breaking choices. Three different motives appears that has affected their gender-breaking educational and professional choices; (I) Making a difference (II) Security in working-life and (III) Skills and knowledge seeking. These motives challenge notions of gender as well as other aspects of an “ideal” job and career for men.The study concludes that the informants' gender-breaking higher education choices have been preceded by a process of different types of events in the transition to working life, as well as connections and networking with other individuals in the adult life who have influenced their career and decision-making. It is found that social capital and heterogeneous network has a significant role for the informant’ gender-breaking education and careers choices - e.g. male role models, inspirers such as professionals in primay and secondary education and colleagues in the world of work, who have contributed to changing their stereotypical notions of female-dominated professions, new preferences and altruistic goals such as helping others, themselves and their future.

Syftet med studien är att få en helhets förståelse för sociala nätverkens betydelse i etableringen på den svenska arbetsmarknaden för arabisktalande och persisktalande individer som har invandrat till Sverige. Studien ämnar även att besvara på hur informanterna använder sitt sociala nätverk för etablering på arbetsmarknaden, på vilket sätt de upplever att kompetenser och kunskap har för betydelse i etableringen på den svenska arbetsmarknaden samt vilken betydelse platsen har för nätverkande och etablering.Studien har genomförts med en kvalitativ metod där sju informanter intervjuades. I ramen av den föreliggande studien använde vi oss av tidigare forskning med en relevant koppling till studiens syfte och frågeställningar. Den insamlade empirin analyserades med utgångspunkt i Hodkinsons och Sparkes Careership-teori, Pierre Bourdieus kapitalteori och Robert D. Putnams teori om sammanbindande och överbryggande socialt kapital. Vidare analyserades deninsamlade empirin utifrån social nätverksanalys. Studiens resultat kring nätverkande pekar på att informanterna har använt sig av olika vägar för etableringen på arbetsmarknaden. Det som framkommer tydligt är att för vissa informanter har sammanbindande och överbryggande socialt kapital haft en betydelse för etableringen. Resultatet visar tydligt att utbildning kan en avgörande betydelse för etableringen. Andra faktorer som kan påverka etableringen är språkkunskapen och arbetslivserfarenheter enligt informanternas berättelser. Vidare har det framkommit att geografiska läget har en nära koppling till informanternas livskontext. Utifrån studiens resultat tyder allt på att det svenska språket är den mest avgörande aspekten för nätverkandet och etableringen. / The purpose of the study is to gain a holistic understanding of the importance of social networks in the establishment in the Swedish labor market for Arabic-speaking and Persian-speaking individuals who have immigrated to Sweden. The study intends to answer how immigrants use their social network to establish themselves in the labor market, it also tends to understand in which way the informants experience that competence and knowledge are important in the establishment in the Swedish labor market. Lastly, it aims to understand what significance the place has for networks and establishment.The study was conducted using a qualitative method where seven informants were interviewed. In the framework of the related study, we used previous research with a relevant connection to the study's purpose and issues. The collected empirical data were analyzed on the basis of Hodkinson's and Sparkes Careership-theory, Pierre Bourdieu's capital theory and Robert D. Putnam's theory of connecting and bridging social capital. Furthermore, the study was conducted with the help of an egocentric network analysis. The results of the study indicate that the informants have used different paths for establishment in the labor market. What is clear is that for some informants, connecting and bridging social capital has been important for the establishment. The results clearly show that education is of crucial importance for the establishment. Other factors that can affect the establishment are language skills and work experience according to the informants’ stories. Furthermore, it has emerged that the geographical location has a close connection to the informants' life context. Based on the results of the study, everything indicates that the Swedish language is the most crucial aspect for networking and establishment.

Globally, the incidence of infection caused by Neisseria gonorrhoeae is the second highest among the bacterial sexually transmitted infections. In Canada, declining rates during the 1990s suggested progress toward curbing gonorrhea; however, those have been increasing since 1999, with rates in Saskatchewan among the highest in the country. Infection can cause serious complications in men and women, and reported resistance to third-generation cephalosporins could lead to potentially untreatable infections. Increased understanding of gonorrhea transmission dynamics, sexual networks, and predictors of antimicrobial resistance development is needed to inform the development of improved approaches to prevention and treatment. The research presented herein draws upon data from Shanghai, China, and Saskatchewan, Canada, to compare and contrast varying epidemiologic approaches to enhancing understanding of gonorrhea in the two settings. Using traditional statistical approaches, multi-level statistical modeling, social network analysis, and dynamic simulation modeling, questions related to sexual behavior, partner presentation, and antimicrobial resistance development are explored. Each technique is evaluated for its potential contribution to overall understanding of the issues related to the ongoing gonorrhea epidemic, globally, and in Saskatchewan. The relative strengths and limitations of the application of the analytical approaches in the different settings are described. Socio-demographic characteristics provided useful indicators of antimicrobial resistant infection among patients with gonorrhea from Shanghai. Further, socio-demographic characteristics were also useful for predicting presentation of a partner for testing and treatment and the use of condoms during intercourse, among this study population. In Saskatchewan, socio-demographic characteristics were useful in predicting coinfection with gonorrhea and chlamydia at the time of diagnosis as well as repeat infection with gonorrhea. Social network analysis of the Saskatchewan dataset provided little additional understanding of the gonorrhea epidemic in the province. This result was largely related to how STI data are collected and stored in the province. The utility of dynamic simulation modeling to investigate the potential impact of antimicrobial resistance in Saskatchewan was also limited due to the same data constraints. However, the insight gained from the model building process and findings from the working model did offer a starting point for conversations around the best ways to postpone the development of antimicrobial resistance in N. gonorrhoeae in Saskatchewan, as well as contribute additional information about how the ways in which STI data are collected and stored in the province considerably restrict the applicability of otherwise powerful epidemiologic tools. With persistently high rates of disease transmission, and the threat of untreatable infections due to antimicrobial resistance, N. gonorrhoeae remains a substantial public health threat locally and globally. The research presented herein describes various approaches to understanding and controlling this disease, applied in contrasting settings. There are a wide variety of elements that should be considered when choosing the appropriate tool(s) to address gonorrhea in a given population; there is no “one size fits all” solution. The local epidemiology of disease, cultural and behavioural norms, the characteristics of the notifiable disease reporting and information systems, and the availability of suitable data all affect the relative strengths and weaknesses of the available analytic methods and disease control approaches.
