Tocqueville in Miami : political culture and political organizing in Miami's Cuban community

This study examines the effectiveness of civic organizations focusing on leadership and the role of culture in politics. The study is based on a quasi-experimental research design and relies primarily on qualitative data. The study focuses on Miami's Cuban community in order to examine the role of public initiative in grassroots civic and community organizations. The Miami Cuban community is a large, institutionally complex and cohesive ethnic community with dense networks of community organizations. The political and economic success of the community makes it an opportune setting for a study of civic organizing. The sheer number of civic organizations to be found in Miami's Cuban community suggests that the community's civic organizations have something to do with the considerable vibrancy and civic capacity of the community. How have the organizations managed to be so successful over so many years and what can be learned about successful civic organizing from their experience? Civic organizations in Miami's Cuban community are overwhelmingly ethnic-based organizations. The organizations recreate collective symbols that come from community members' memories of and attachments to the place of origin they hold dear as ethnic Cubans. They recreate a collective Cuban past that community members remember and that is the very basis of the community to which they belong. Cuban Miami's ethnically based civic organizations have generally performed better than the literature on civic organizations says they should. They gained greater access to community ties and social capital, and they exhibited greater organizational longevity. The fit between the political culture of civic organizations and that of the broader political community helps to explain this success. Yet they do not perform in the same way or in support of the same social purposes. Some stress individual agency rather than community agency, and some pursue an externally-oriented social purpose, whereas others focus on building an internal community.

On the Bleeding Edge : Debloating Internet Access Networks

As ever more devices are connected to the internet, and applications turn ever more interactive, it becomes more important that the network can be counted on to respond reliably and without unnecessary delay. However, this is far from always the case today, as there can be many potential sources of unnecessary delay. In this thesis we focus on one of them: Excess queueing delay in network routers along the path, also known as bufferbloat. We focus on the home network, and treat the issue in three stages. We examine latency variation and queueing delay on the public internet and show that significant excess delay is often present. Then, we evaluate several modern AQM algorithms and packet schedulers in a residential setting, and show that modern AQMs can almost entirely eliminate bufferbloat and extra queueing latency for wired connections, but that they are not as effective for WiFi links. Finally, we go on to design and implement a solution for bufferbloat at the WiFi link, and also design a workable scheduler-based solution for realising airtime fairness in WiFi. Also included in this thesis is a description of Flent, a measurement tool used to perform most of the experiments in the other papers, and also used widely in the bufferbloat community.

Women's writing networks in Spanish magazines around 1900

As an output of the HERA Travelling Texts project, created with the aim of uncovering the realities of women’s literary culture on the fringes of Europe during the long nineteenth century, this study was conceptualised to find out more about the networks of women writers in Spain around 1900, using the digitised corpuses of contemporaneous periodicals as the primary source material. Each chapter of the study centres on a particular periodical, which is used as the starting point for the community of writers and readers, both real and imagined. This thesis looks at the realities of the literary culture for creative women in the late nineteenth century-early twentieth century, exploring the strategies used by women (and men) to support each other in their literary endeavours, how they took inspiration and courage from each other, how they promoted their own names, and how they were received by wider society. The study will also focus on the transnational nature of this literary culture, looking at how women of different nations influenced each other’s work, with a view to understanding more about how cultural change takes place. Finally, this thesis hopes to persuade the reader that the periodical is a rich and under-utilised resource for discovering more about the lives of women writers and their network of relationships.
