An analysis of hatching success in the great reed warbler Acrocephalus arundinaceus

Hatching success is a potentially important fitness component for avian species. Previous studies of hatching success in natural populations have primarily focused on effects of inbreeding but a general understanding of variation in hatching success is lacking. We analyse data on hatching success in a population of great reed warblers Acrocephalus arundinaceus in Lake Kvismaren in south central Sw

Multi-organizational Emergency Response Management - A Framework for Further Development

This doctoral thesis suggests a framework for how multi-organizational emergency response management can be understood. A method for collecting and analyzing data on individuals and their interactions has been developed and tested. The method is rooted in social network theory and facilitates further exploration of the complexity associated with responses to emergencies in which various resources

The Activity Diamond - Modeling an Enhanced Accessibility

The purpose of the research presented in this thesis is to enhance the field of accessibility to include a multitude of perspectives. Based on cultural-historical activity theory (CHAT), it analyzes how human, artifactual and natural factors impact an individual’s possibilities to act in concrete situations that are part of a systemic whole.The thesis presents two main results:An enhanced accessib

PPs, particles and polysemy of a basic Swedish speech act verb

Every language has a set of verbs which denote the various actions we perform when we communicate through spoken language. In linguistic literature, these are commonly referred to as speech act verbs and they typically include communicative categories like asking, answering, promising, accusing, telling and a host of others. Most speech act verbs have very specific meanings which limit their usage

Multiple Scattering, Underlying Event, and Minimum Bias

In this talk I first discuss the experimental evidence for multiple scattering and the properties of the underlying event. The extensive analyses by Rick Field of data from CDF cannot be reconciled with traditional wisdom concerning multiple collisions and the AGK cutting rules. Data seem to imply some kind of color recombination or unexpectedly strong effects from pomeron vertices. I then discuss

Characterization of MIMO antennas with multiplexing efficiency

A simple and intuitive metric of multiplexing efficiency is proposed for evaluating the performance of MIMO antennas in the spatial multiplexing mode of operation. The metric is particularly useful for antenna engineers whose goal is to achieve the optimum antenna system design. Experimental results involving prototype mobile terminals highlight the effectiveness of our proposal.
