Competing Under Pressure : State Anxiety, Sports Performance and Assessment
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Elevated levels of anxiety are a common response to stressful competitive sports situations, are known to moderate athletic performance and are referred to as an unpleasant emotional state associated with perceptions of situational threat. The empirical studies in this dissertation considered primarily psychometric, methodological and conceptual issues of relevance for the study of anxiety and sports performance. In Study I, athletes were followed across a full competitive season to explore patterns of inter- and intra-individual variability of anxiety and self-confidence in relation to performance. The findings imply intra-individual anxiety and self-confidence variability to affect performance differently than the specific intensity level and are discussed in relation to more stable personality dispositions such as private self-consciousness. Study II evaluated the psychometric properties of the 27-item Competitive State Anxiety Inventory-2 (CSAI-2) and alternative versions of this scale. General support for a 17-item version (CSAI-2R) was found, but there are also psychometric limitations future research needs to resolve. Study III investigated assessment of intensity and directional ratings on single anxiety items with reference to the conceptualisation of anxiety symptoms as interpreted on a debilitative-facilitative continuum. The findings question the importance and rationale of assessing anxiety direction and revealed serious concerns with assessment procedures and statistical techniques applied in previous research. These concerns were also supported in Study IV, which explored athletes’ idiosyncratic experiences of debilitative and facilitative anxiety symptoms in terms of intensity and emotional valence. The findings are discussed and summarised in a model in order to increase conceptual clarity and provide implications for future research regarding anxiety and related emotional performance states.

Pastoral pasts in the Amboseli landscape : An archaeological exploration of the Amboseli ecosystem from the later Holocene to the colonial period
- 2018

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Amboseli ecosystem, home of Amboseli National Park, is renowned for its extraordinary biodiversity, and has long drawn the attention of conservationists and ecologists hoping to safeguard the healthy functioning of this Kenyan rangeland and the pastoral traditions that have brought this landscape into being. There is major concern currently however, as present day Amboseli pastoral livelihoods are said to be in decline owing to rangelands being settled, fenced, and converted to farmland. The processes by which pastoral livelihood diversification is occurring in this landscape have historical roots, and appreciating this context is an important component of understanding current trends in socio-economic and environmental adaptability and sustainability. Yet, the human history of Amboseli’s ecosystem tends to be conceptualised and discussed by scholars in terms of a narrow and ahistorical model of subsistence-based pastoralism. The research presented in this thesis provides an alternative history of pastoral pasts in Amboseli.In more specific terms, the primary focus of this thesis is detailing and analysing the results of archaeological surveys and the excavation of ten sites located on Olgulului/Ololarashi group ranch, an archaeological terra incognita. These date to varying stages of the last few millennia. Inspired by the interdisciplinary approach of historical ecology, these exploratory archaeological findings are contextualised and integrated with archival, palaeoenvironmental, ecological, linguistic, and local knowledge sources. In doing so, I present a culture history of Amboseli, and an examination of the evidence for livestock herding in this landscape organised into three parts: the mid-Holocene arrival of domestic stock and emergence of specialised pastoralism; the Early to Late Iron Ages; and finally, the 19th century and colonial period. Throughout these chapters, a continuous theme discussed is the multitude of ways in which cultivation and trade have featured in the Amboseli landscape and contributed to the livelihoods of pastoral people inhabiting this ecosystem. In delving into the history of pastoralism in Amboseli, it is apparent that both its occupants’ livelihoods and the landscape itself must be understood as having been shaped by a heterogeneity of economic pursuits and resource use strategies.
