The focus of this research is on identifying the determinants of local-level climate change adaptive capacity in Caribbean small island communities. A single case study approach was employed to assess retrospectively both internal and external factors that contributed to the adaptive capacity of Paget Farm, Saint Vincent and the Grenadines. The Caribbean region’s first solar-powered desalination plant was implemented in the community specifically as a climate change adaptation strategy and thus provides an ideal case for retrospective analysis. A series of semi-structured interviews with local residents and key stakeholders revealed a number of interacting social and institutional factors that contribute to community-based adaptive capacity. Further analysis of institutional factors was undertaken using Social Network Analysis, which enabled visualization and quantification of vertical and horizontal institutional integration of the networks formed during different phases of project implementation. The research extends scholarly understanding of the determinants that influence local-level climate change adaptive capacity and provides practical evidence that can assist small island communities to respond to a changing climate.

The thesis focuses on the social web and on the analysis of social networks with particular emphasis on their temporal aspects. Social networks are represented here by Time Varying Graphs (TVG), a general model for dynamic graphs borrowed from distributed computing. In the first part of the thesis we focus on the temporal aspects of social networks. We develop various temporal centrality measures for TVGs including betweenness, closeness, and eigenvector centralities, which are well known in the context of static graphs. Unfortunately the computational complexities of these temporal centrality metrics are not comparable with their static counterparts. For example, the computation of betweenness becomes intractable in the dynamic setting. For this reason, approximation techniques will also be considered. We apply these temporal measures to two very different datasets, one in the context of knowledge mobilization in a small community of university researchers, the other in the context of Facebook commenting activities among a large number of web users. In both settings, we perform a temporal analysis so to understand the importance of the temporal factors in the dynamics of those networks and to detect nodes that act as “accelerators”. In the second part of the thesis, we focus on a more standard static graph representation. We conduct a propagation study on YouTube datasets to understand and compare the propagation dynamics of two different types of users: subscribers and friends. Finally, we conclude the thesis with the proposal of a general framework to present, in a comprehensive model, the influence of the social web on e-commerce decision making.

The subject of this graduate thesis is primarily identification of influencers on the social network Facebook, group FM VŠE. Furthermore, the thesis deal with verification of influence power of influencers and comparison with the power of less influential people at the Faculty of Management. Thanks to literature review from international environment is in the thesis described the term influencer and for the purpose of identification of influencers is there also description of the theory of social network analysis. Identification is performed by analysing of the social network Facebook and for verification of powerful of influence is used questionnaire.

Social networks - a description of principles and theoretical background, dynamics and possibilities of their use, particularly in management and marketing; methods for detection of social networks and work with them, the available software tools, the practical application of theoretical knowledge - analysis of specific data structures and social networks subsequent processing with regard to potential applications in management

Commercial usage of social networking is one of the most discussed topic in marketing these days. There are two general ways how to use social network -- to built communities of social networks' users and to advertise in classic display advertising. Czech companies do not place social network to their communication mix so often as foreign ones. They still have to learn how to create the most effective strategy and how to communicate with users. The most important is the activity and interaction. Only then the campaign can reach the communication goals.

Web 2.0 is a term describing the second stage of the web devel-opment in which static websites and presentations have trans-formed and continue to transform into a dynamic environment filled with user interaction and interpersonal communication. The aim of the diploma thesis was to introduce the reader to the term Web 2.0, describe the possibilities of its use and point out examples of successful application in practice. The first part of the diploma thesis tries to explain the term Web 2.0, define its basic properties and specify its typical ap-plications. The second part characterizes new generations of Internet users, provides description of the individual uses of Web 2.0 tools and services and summarizes their advantages and disadvantages. The final chapter provides examples of the use of the said tech-nologies and processes in practice which serve as a basis for evaluation of the current approaches and recommendations for potential users.

Internal communication is a subject increasing in importance. This subject has, as many other things, been influenced by the Internet-based and connected world that we live in today. As a result, Enterprise Social Networks has appeared as a tool for organisations to use. While the usage of this tool is growing, the existing research on the subject is yet very limited. So is the research on employees‘ needs when it comes to internal communication. In this study, we aim to fill these gaps, by exploring the use of these enterprise social networks from an organisational actor‘s perspective. In order to fulfil this purpose, a qualitative case study within multiple embedded units of analysis was used. The empirical material was gathered through in-depth semi- structured interviews as well as observations. Furthermore, we took on real-life experience by using the ESN tool ourselves. Several themes were then identified using a thematic analysis. By using this method, we conclude that organisational actors use ESNs for private, public and remote communication. We also provide the reader with five characteristics of ESNs that are perceived as important by organisational actors, namely; easy to learn, easy to use, accessible, informal and avoids disturbance. Several perceived outcomes resulting from ESN usage is then identified. We conclude the study by explaining that if organisations identify a need for an ESN, use it in the right way, and have the appropriate culture, the implementation of an ESN can be very beneficial. This, as organisational actors experience it as a good tool for internal communication.

The subject of this thesis is internet labour market in the Czech Republic. The aim of this thesis is to analyse and evaluate the online job market and the tools used by university degree applicants in search for jobs and tools used in online recruitment and selection of employees including future trends outlines. The theoretical part explains the terms such as labour market, online technology and social networks phenomenon and their expected future trends with the help of professional literature. The practical part is based on qualitative research analysing behaviour of the sample of the respondents on the job market and a recruiter work processes in a large media company. The information obtained from the respondents should serve as a recommendation for employers recruiting and selecting employees. The conclusion summarizes the main points resulting from the analysis including the possible online job market trends.

This thesis evaluates why the implementation of a tree plantation project in Chiapas, Mexico, called Scolel Te failed in its attempt to participate in the CDMs scheme. The Scolel Te project brings together farmers and local organisations into a network of exchange of resources that aims at producing an outcome that is only possible through the co-ordination and co-operation of all participants: the emission of carbon certificates. This thesis studies the co-ordination problems that local actors face at the moment of establishing the carbon projects by identifying how formal and informal mechanisms such as contracts, economic incentives, trust, and reputation, create or solve co-ordination problems in the Scolel Te network. The thesis also describes how changes in the distribution of power among actors affect the functioning of the network and how individual's interests and strategic alliances have the potential of derailing the aims of the environmental project. For such purposes, this thesis analyses the exchange relationships among actors at the micro level and identifies how exchange relationships evolve over time. Then an overall picture of the exchange relationships is presented (macro level) with focus in understanding how and why power in the network is exerted. Findings suggest that relying on economic incentives as the main mechanism to generate commitment among communities has failed to create stable exchange relationships in the long term. Trust and reputation are stronger mechanisms to achieve commitment. Moreover, we find that the ability to generate commitment depends highly on the generation of interdependencies between tree plantation projects and the main economic activities of local actors. However, type of land tenure, main economic activity, and pre-existing power relationships embedded at local level are also the principal factors that determine the dynamism of the social exchange relationships and commitment in the long-run. This thesis considers that co-ordination failure occurs because a lack of knowledge about the real dependencies between local actors and their natural resources in the design of CDMs. At macro level, this thesis found that the lack of accountability of the unregulated local carbon market at local level has created unintended incentives for actors to adopt less environmentally responsible strategies and disincentive participation in the CDMs.

Following the financial crisis that began in 2007, various groups and individuals demanded an ecologically diverse banking sector to help spread risk in the banking industry and to more effectively cater to customer needs. To date, however, measures to change retail banking have been limited to modest structural and incentive adjustments to boost competition and modify the banking culture which prompts an investigation about the nature of the ethical banking sector and its ability to grow and thrive. The lack of progress in reforming banking in the UK raises questions of whether and how we could encourage and sustain ethical, social and non-profit alternatives to current high street banks. Because prior academic research in ethical has been limited, the research aims to fill gaps with regards to understanding the network established between ethical banks their business models and to identify the type of intervention needed to promote ethical banking as an alternative to established mainstream retail banking.The research presented in this thesis investigates how the ethical banking sector is embedded in the UK financial services industry and draws out political-economic dynamics that facilitate as well as hinder the development of the sector. To this end, the thesis develops a conceptual framework that draws on literatures on industrial districts and embeddedness. The thesis also models and analyses the ethical banking network using social network analysis, before developing an understanding of ethical banks’ business models and how the sector is organised within the banking industry. Data on the banks’ relationships with other organisations were gathered through questionnaires, and interviews were conducted with respondent firms to explore ethical banking as a sector from the perspective of ethical banks themselves. In addition, company, industry and legislative publications have been analysed to add context and validate findings.At the broadest level, the results draw a picture of ethical banking as a diverse but disorganised subsector which is dominated by two players and lacks prospects to develop into an alternative banking sector that could compete with the full banking services offered by high street competition. Only if the sector manages to reorganise itself internally with support from external players could it form a more coherent and centralised subsector with a clear and shared understanding as to what its ambitions are. Thus the research highlights the potential of ethical banking which is expanding rapidly, but, at the same time, the research also raises the difficulties in developing ethical banking as a sector which retains its distinctiveness from high street banks. In sum, the research findings are in line with current ambitions to develop and promote a more diverse and sustainable UK banking industry: ethical banks should receive more attention from policy makers as they are a set of diverse actors that has grown significantly since the beginning of the financial crisis and, could if strengthened, contribute to developing a stronger retail banking sector more responsive to customer needs. Government efforts to reorganise banking should include developing ethical banking as an alternative to Plc retail banks which would change competition by increasing consumer choice instead of creating yet more large scale banks.
