Die vorliegende Dissertation verfolgt das Ziel, zu untersuchen, wie sich ehemalige Schweizer Nachwuchs-Elite-Athleten unter dem Aspekt des sportlichen Erfolgs entwickelt haben und wie sich ihre heutige Lebenssituation präsentiert. Zudem will die Arbeit ergründen, inwiefern der sportliche Erfolg durch ausgewählte institutionelle, sportwissenschaftliche und individuelle Parameter vorhergesagt werden kann. Zu diesem Zweck wurden alle deutschsprachigen Nachwuchs-Elite-Athleten untersucht (N = 221), welche im Jahre 1999 Inhaber einer Swiss Olympic Talent-Card waren. Die Prädiktoren stammen teilweise aus einer ersten schriftlichen Befragung, welche 1999 durchgeführt wurde (Rücklauf: 79%). Die Daten für die Beschreibung der Laufbahn sowie der heutigen Situation wurden im Sommer 2011 durch eine weitere schriftliche Befragung erhoben (Rücklauf: 48%). Die Daten wurden mit deskriptiven, inferenzstatistischen, cluster- sowie regressionsanalytischen Verfahren ausgewertet. Die Resultate zeichnen insgesamt ein positives Bild. Trotz verschiedener Hürden im Nachwuchsalter schafften die meisten befragten Athleten den Sprung in die Elite-Stufe. Knapp ein Drittel von ihnen konnte dabei grosse Erfolge (Medaillengewinn) an bedeutenden internationalen Wettkämpfen erringen. Die bereits zurückgetretenen Athleten scheinen das Laufbahnende grösstenteils gut bewältigt zu haben, was wohl damit zusammenhängt, dass die Mehrheit von ihnen freiwillig zurückgetretenen ist und konkrete Pläne für die nachsportliche Laufbahn hatte. Insgesamt deuten die Ergebnisse darauf hin, dass sich ein Engagement im Leistungssport nicht negativ auf die Entwicklung in anderen Lebensbereichen auszuwirken scheint. So zeigte sich, dass sich die heutige Situation der ehemaligen Nachwuchs-Elite-Athleten in gesundheitlicher, psychologischer, sozialer, beruflicher und finanzieller Hinsicht durchwegs positiv präsentiert – in gesundheitlicher, beruflicher und finanzieller Hinsicht sogar besser als jene von gleichaltrigen Vergleichspersonen der Schweizer Bevölkerung. Bei der Vorhersage des sportlichen Erfolgs zeigte sich, dass Athleten aus weniger geförderten und weniger bedeutenden Sportarten später insgesamt erfolgreicher sind an bedeutenden internationalen Wettkämpfen. Darüber hinaus erwies sich die mentale Stärke als langfristiger Erfolgsfaktor. Die Ergebnisse erweitern das bestehende Wissen über Laufbahnen von Leistungssportlern sowie über Determinanten von sportlichem Erfolg generell, besonders aber hinsichtlich des Schweizer Sportsystems. Athleten und ihr Umfeld erhalten dadurch einen vertieften Einblick in die Chancen und Risiken eines Engagements im Leistungssport. Swiss Olympic und die Verbände gewinnen ein besseres Verständnis darüber, wie sich Nachwuchs-Elite-Athleten in ihrer sportlichen Entwicklung noch besser unterstützen lassen. Bund, Kantone und Gemeinden können anhand der Ergebnisse besser abschätzen, inwiefern sich die Förderung des Spitzensports durch öffentliche Gelder rechtfertigen lässt.

Commercial actors play an essential role in the organisational structure of snowboarding by sponsoring athletes, arranging events, contributing to product development and developing long-term partnerships with other key actors. However, the particularities of their role in the alternative sports cultures which are related to brand marketing strategies have not been extensively researched. Based on Hitzler and Niederbachers (2010) framework of social scenes, Stegbauers (2008) social network and Adjouri and Stastnys (2006) branding theories, analysis is carried out using an ethnographic approach. This includes participant observation of relevant events and semi-structured interviews with over forty key actors of the sport to examine the roles and activities of core actors within snowboarding. The findings reveal that brands have gained an important position within the scene; where they can build partnerships with other core and periphery actors in order to market particularly identities, lifestyles and products. This contributes to the development of a sport which is dependent on brands for its continuity. By using promotional strategies of sponsoring athletes, organising events and feeding media with scene-related content, the aesthetical values of the snowboarding sport are communicated and transferred, while ensuring exposure of the brand’s image and lifestyle. Social contacts as well as knowledge on particularities of the sport allow the commercial actors to gain an influential position and identity within the snowboarding core culture.

Volunteers are the most important resource for non-profit sport clubs seeking to bolster their viability (e.g. sporting programs). Although many people do voluntary work in sport clubs, stable voluntary engagement can no longer be granted. This difficulty is confirmed by existing research across various European countries. From a club management point of view, a detailed understanding of how to attract volunteers and retain them in the long term is becoming a high priority. The purpose of this study is (1) to analyse the influence of individual characteristics and corresponding organisational conditions on volunteering in sports clubs as well as (2) to examine the decision-making processes in relation to implement effective strategies for recruiting volunteers. For the first perspective a multi-level framework for the investigation of the factors of voluntary engagement in sports clubs is developed. The individual and context factors are estimated in different multi-level models based on a sample of n = 1,434 sport club members from 36 sport clubs in Switzerland. Results indicate that volunteering is not just an outcome of individual characteristics such as lower workloads, higher income, children belonging to the sport club, longer club memberships, or a strong commitment to the club. It is also influenced by club-specific structural conditions; volunteering is more probable in rural sports clubs whereas growth-oriented goals in clubs have a destabilising effect. Concerning decision-making processes an in-depth analysis of recruitment practices for volunteers was conducted in nine selected sport clubs (case study design) based on the garbage can model. Results show that the decision-making processes are generally characterised by a reactive approach in which dominant actors try to handle personnel problems of recruitment in the administration and sport domains through routine formal committee work and informal networks. In addition, it proved possible to develop a typology that deliver an overview of different decision-making practices in terms of the specific interplay of the relevant components of process control (top-down vs. bottom-up) and problem processing (situational vs. systematic). Based on the findings some recommendations for volunteer management in sport clubs are worked out.

A debate about Caster Semenya's female sex began shortly after the South African runner won gold in the women’s 800m final at the 2009 Athletic World Championships held in Berlin. Her victory was disputed through questions about her right to compete as a ‘woman’, with the International Association of Athletics Federation (IAAF) announcing she would be required to undergo a gender verification test before her victory could be confirmed. Using the theoretical frame of social constructionism (Berger & Luckmann), poststructuralism (Foucault), gender- and postcolonial theories (Butler; Hall; Spivak) and the methodology of critical discourse analysis (Jaeger), the paper explores the way the possible intersexuality of Caster Semenya was contextualised in mainstream Swiss German-language print media. The analyses will firstly look at the way in which Caster Semenya was constructed as a ʻfallen hero’ and stigmatised as a double-dealer and unacceptable deviant body. The rumours amongst athletes and commentators became news in the media, which focused on descriptions of her habitus, her muscular body and her deep voice. Through theoretical discussion the paper argues that the media response to Caster Semenya exemplifies Butler’s claim that the discursive framework of gender constructs and naturalises sex. A key question is therefore whether the designation of deviant bodies to a ʻfield of deformation’ (Butler) works to pluralise the field of gender, or rather, as Butler suggests, it tends that those bodies might call into questions. The final part of the paper discusses how gender, ethnicity and sexuality combine to constitute the black female sporting body as a spectacle of otherness. It is evident that this otherness is made manifest through the function of those bodies as a site of transgression, as the boundary between male and female, and often as the boundary between culture and nature (Hall). Using the example of the controversy surrounding Caster Semenya, this paper aims to demonstrate how the post/colonial white female body is reproduced by western norms of gender, sexuality, beauty and sporting behaviour, in the sense of a feminine sporting genderperformance. The media controversy will be also read through the lens of the globalisation of certain ideas of normative bodies, sex, ethnicity and gender and the challenge of changing stereotypes through transgression. Keywords: gender- and postcolonial theories, discourse analysis, print media, Caster Semen-ya, deviant body, ethnicity, intersexuality

Forest management not only affects biodiversity but also might alter ecosystem processes mediated by the organisms, i.e. herbivory the removal of plant biomass by plant-eating insects and other arthropod groups. Aiming at revealing general relationships between forest management and herbivory we investigated aboveground arthropod herbivory in 105 plots dominated by European beech in three different regions in Germany in the sun-exposed canopy of mature beech trees and on beech saplings in the understorey. We separately assessed damage by different guilds of herbivores, i.e. chewing, sucking and scraping herbivores, gall-forming insects and mites, and leaf-mining insects. We asked whether herbivory differs among different forest management regimes (unmanaged, uneven-aged managed, even-aged managed) and among age-classes within even-aged forests. We further tested for consistency of relationships between regions, strata and herbivore guilds. On average, almost 80 of beech leaves showed herbivory damage, and about 6 of leaf area was consumed. Chewing damage was most common, whereas leaf sucking and scraping damage were very rare. Damage was generally greater in the canopy than in the understorey, in particular for chewing and scraping damage, and the occurrence of mines. There was little difference in herbivory among differently managed forests and the effects of management on damage differed among regions, strata and damage types. Covariates such as wood volume, tree density and plant diversity weakly influenced herbivory, and effects differed between herbivory types. We conclude that despite of the relatively low number of species attacking beech; arthropod herbivory on beech is generally high. We further conclude that responses of herbivory to forest management are multifaceted and environmental factors such as forest structure variables affecting in particular microclimatic conditions are more likely to explain the variability in herbivory among beech forest plots.

The heat waves of 2003 in Western Europe and 2010 in Russia, commonly labelled as rare climatic anomalies outside of previous experience, are often taken as harbingers of more frequent extremes in the global warming-influenced future. However, a recent reconstruction of spring–summer temperatures for WE resulted in the likelihood of significantly higher temperatures in 1540. In order to check the plausibility of this result we investigated the severity of the 1540 drought by putting forward the argument of the known soil desiccation-temperature feedback. Based on more than 300 first-hand documentary weather report sources originating from an area of 2 to 3 million km2, we show that Europe was affected by an unprecedented 11-month-long Megadrought. The estimated number of precipitation days and precipitation amount for Central and Western Europe in 1540 is significantly lower than the 100-year minima of the instrumental measurement period for spring, summer and autumn. This result is supported by independent documentary evidence about extremely low river flows and Europe-wide wild-, forest- and settlement fires. We found that an event of this severity cannot be simulated by state-of-the-art climate models.
