Abstract:
As a unique habitat that encompasses steep environmental gradients, it is important to evaluate threats posed to the intertidal zone by rapid climate change. It is thought that intertidal ectotherms are living close to their physiological limit; therefore slight changes in temperature could result in high levels of mortality. Past studies on intertidal species measured thermal tolerance under constant temperatures, neglecting to consider the impacts of natural variation in field temperatures. I conducted a study on the barnacle, Balanus glandula, to assess if a variable thermal environment wou

Abstract:
Antimicrobial resistance is a serious and imminent threat to human health, though its rise may be controlled with improved stewardship strategies that limit the emergence and spread of resistant strains. Motivated by theoretical models from population genetics and ecology, my M.Sc. experimentally evaluates how varying drug availability in either time or space impacts the prevalence of resistance in a population. By experimentally evolving Pseudomonas aeruginosa under different antibiotic selection regimes in vitro, I show that spatial, but not temporal, drug free refuges delay the fixation of

Abstract:
This dissertation is a cross-national investigation of the relationship between cultural heterogeneity and regimes' respect for basic human rights. The quantitative human rights literature has not yet addressed the question of whether high levels of cultural diversity are beneficial or harmful. My research addresses this gap. I address the debate between those who argue that diversity is negatively related to basic human rights protection and those who argue it is likely to improve respect for these rights. Ultimately, I propose that regimes in diverse countries will be less likely to provide

Abstract:
Water resources in hard rock terrain are difficult to characterize due to heterogeneity and anisotropy in the fracture network, low porosities and limited recharge volumes available during the summer season. Three methods were developed and evaluated in order to assist in water supply planning. A groundwater resources potential index was estimated using multivariate statistics, where physical and geological variables were classified using Analysis of Variance and Fisher's Least Significant Difference tests according to their effect on hydraulic properties.

Abstract:
This paper analyses the role of the spatial structure of migrant networks in the location decision of migrants to the European Union at the regional level. Using a random parameters logit specification, a significant positive effect of migrant networks in neighbouring regions on migrants' location decisions is found. Although this spatial spillover effect is smaller than the effect of networks in the host regions, omitting to control for this spatial dependence results in a 40% overestimation of the effect of regional migrant networks on the location decision of newly arriving migrants.

The present thesis explores the internationalisation of firms in relation to regionsector characteristics.

In the introductory chapter we provide a general conceptual framework and selective review of the literature. Our starting point is that internationalisation is heterogenous across firms as it requires ownership advantages. Ho

Fire is central to the maintenance of pine sandhill communities and two conceptual hypothesis regarding burn frequency have come to light in maintaining the unique species composition and richness of these

Commodities are known to exhibit a cyclical behavior. The present work studies the dynamics of commodities regimes and their portfolio diversification properties. Using an extension of the regime-switching model, we find that the twelve commodities studied can be clustered into four classes with different regime dynamics. This demonstrates that commodities are far from having a homogenous asset class behavior. The existence of two regimes is transversal to the assets studied. One regime marked by a high volatility and the other by a low volatility. In both regimes, most of the commodities exhi
