On and off air: an ethnographic exploration of minority radio in Portugal

Taking a Media Anthropology’s approach to dynamics of mediated selfrepresentation in migratory contexts, this thesis starts by mapping radio initiatives produced by, for and/or with migrants in Portugal. To further explore dynamics of support of initial settlement in the country, community-making, cultural reproduction, and transnational connectivity - found both in the mapping stage and the minority media literature (e.g. Kosnick, 2007; Rigoni & Saitta, 2012; Silverstone & Georgiou, 2005) - a case study was selected: the station awarded with the first bilingual license in Portugal. The station in question caters largely to the British population presenting themselves as “expats” and residing in the Algarve. The ethnographic strategy to research it consisted of “following the radio” (Marcus, 1995) beyond the station and into the events and establishments it announces on air, so as to relate production and consumption realms. The leading research question asks how does locally produced radio play into “expats” processes of management of cultural identity – and what are the specificities of its role? Drawing on conceptualizations of lifestyle migration (Benson & O’Reilly, 2009), production of locality (Appadurai 1996) and the public sphere (Butsch, 2007; Calhoun & et al, 1992; Dahlgren, 2006), this thesis contributes to valuing radio as a productive gateway to research migrants’ construction of belonging, to inscribe a counterpoint in the field of minority media, and to debate conceptualizations of migratory categories and flows. Specifically, this thesis argues that the station fulfills similar roles to other minority radio initiatives but in ways that are specific to the population being catered to. Namely, unlike other minority stations, radio facilitates the process of transitioning between categories along on a continuum linking tourists and migrants. It also reflects and participates in strategies of reterritorialization that rest on functional and partial modes of incorporation. While contributing to sustain a translocality (Appadurai, 1996) it indexes and fosters a stance of connection that is symbolically and materially connected to the UK and other “neighborhoods” but is, simultaneously, oriented to engaging with the Algarve as “home”. Yet, besides reifying a British cultural identity, radio’s oral, repetitive and ephemeral discourse particularly trivializes the reproduction of an ambivalent stance of connection with place that is shared by other “expats”. This dynamic is related to migratory projects driven by social imaginaries fostered by international media that stimulate the search for idealized ways of living, which the radio associates with the Algarve. While recurrently localizing and validating the narrative projecting an idealized “good life”, radio amplifies dynamics among migrants that seem to reaffirm the migratory move as a good choice.

Valuing an offshore exploration project through real options analysis

This thesis applied real options analysis to the valuation of an offshore oil exploration project, taking into consideration the several options typically faced by the management team of these projects. The real options process is developed under technical and price uncertainties, where it is considered that the mean reversion stochastic process is more adequate to describe the movement of oil price throught time. The valuation is realized to two case scenarios, being the first a simplified approach to develop the intuition of the used concepts, and the later a more complete cases that is resolved using both the binomial and trinomial processes to describe oil price movement. Real options methodology demonstrated to be capable of assessing and valuing the projects options, and of overcoming common capital budgeting methodologies flexibility limitation. The added value of the application of real options is evident, but so is the method's increased complexity, which adversely influence its widespread implementation.

Attachment to parents: the mediating role of inhibition of exploration and individuality on health behaviors

This study’s goal was to analyze whether the quality of university students’ relationship with their parents mediated the association between mental health and physical symptoms and health behavior. Participants were 250 university students (66% female and 34% male), aged between 17 and 29 years old (M = 20.88, SD = 2.03) that answered the Father/Mother Attachment Questionnaire (FMAQ), the Physical Symptoms Scale from the Rotterdam Symptom Checklist (RSCL), the Health Behavior Questionnaire (HBQ), and the Hospital Anxiety and Depression Scale (HADS). The results showed that the indirect effect of physical symptoms on health behavior was significantly mediated by the father’s and mother’s inhibition of exploration and individuality (IEI). Also the indirect effect of psychological distress on health behavior was significantly mediated by the father’s and mother’s IEI. These results suggest that young adults who had more restrictions to their individuality show worse health behaviors. Separation Anxiety and Dependence (SAD) and Quality of Emotional Bond (QEB), the other 2 attachment scales, were not mediators of the relationship between physical symptoms/ psychological distress and health behavior. This study shows the importance of promoting positive parenting practices that contribute to healthier behavior choices and less risky behaviors, as well as the need for more studies that clearly identify these practices in young adult populations.

Exploring scenario exploration

Model finders are very popular for exploring scenarios, helping users validate specifications by navigating through conforming model instances. To be practical, the semantics of such scenario exploration operations should be formally defined and, ideally, controlled by the users, so that they are able to quickly reach interesting scenarios. This paper explores the landscape of scenario exploration operations, by formalizing them with a relational model finder. Several scenario exploration operations provided by existing tools are formalized, and new ones are proposed, namely to allow the user to easily explore very similar (or different) scenarios, by attaching preferences to model elements. As a proof-of-concept, such operations were implemented in the popular Alloy Analyzer, further increasing its usefulness for (user-guided) scenario exploration.

The Irish pub as a third place : a sociological exploration of people, place and identity

There is considerable interest in alcohol in Irish society, yet minimal sociologcial understanding of its consumption, particularly of the sites where most drinking occurs: the country's 8750 pubs. Despite widespread public discussions on the role of the pub, there is scant social science evidence to better inform debate. Pubs are central to Irish community and are key sites of social interaction. American sociologist Ray Oldenburg has argued that "third places" (neither workplace nor home) are crucial to the maintenance of the community and the enhancement of social capital. According to Oldenburg, the role of the third place in the community is to provide continuity, regularity, a sense of place - all of which conceptually contribute to the construction of the self, the projection of the self within the public sphere, the distribution of social capital and the generation of a collective identity. The pub is the archetypal third place, but Oldenburg is concerned that modern pubs are less able to provide this vital function. Social scientists have suggested that community is in a state of fragmentation and decline due to changes in modes of social interaction and a decrease in shared spaces, resulting in a weakened connection to place. Community without propinquity has been characterised by social alienation, fragmentation and what Oldenburg refers to as the "problem of place" (13). Third places, and thus the Irish pub, have been particularly affected. In order to increase the sociological knowledge of the pub in Ireland, this project critically engages with the pub to assess the importance that public drinking houses have in the everyday. Moreover, this research sets out to investigate the people/place relationship using the pub as an investigative lens and examine the ways in which people shape place, place shapes people and how that relationship is implicated in the construction of irish identities. Furthermore, this is also an articulation of a cultural shift within Ireland and Irish places whose effects are deep and multi-layered. This project aims to explore the development of the contemporary geography of identity as the irish pub as a third place is transformed or disappears from the social landscape.

Kommentierte Übersetzung des NASA-Berichtes „Pioneering Space: NASA’s Next Steps on the Path to Mars“ vom Englischen ins Deutsche

Die Bachelorarbeit besteht aus der Übersetzung des NASA-Berichtes „Pioneering Space: NASA’s Next Steps on the Path to Mars“ vom Englischen ins Deutsche und einer Textanalyse nach dem Analysemodell von Christiane Nord. Dieser Analyseansatz wird grob nach den sog. textexternen und textinternen Faktoren aufgeteilt. Zu den Besonderheiten und Herausforderungen der Übersetzung werden u.a. das hohe fachsprachliche Textniveau sowie diverse Abkürzungen und Abteilungsnamen innerhalb der NASA, die im Bericht auftauchen, gehören. Da darüber hinaus die Berichte und Kommunikation in der Weltraumszene hauptsächlich in englischer Sprache erfolgt, muss ein Kompromiss gefunden werden, um die Wörter so im Text einzubringen, dass der Textfluss nicht übertrieben gestört wird.
