Mobile Agents for Mobile Tourists: A User Evaluation of Gulliver's Genie
How mobile computing applications and services may be best designed, implemented and deployed remains the subject of much research. One alternative approach to developing software for mobile users that is receiving increasing attention from the research community is that of one based on intelligent agents. Recent advances in mobile computing technology have made such an approach feasible. We present an overview of the design and implementation of an archetypical mobile computing application, namely that of an electronic tourist guide. This guide is unique in that it comprises a suite of intelligent agents that conform to the strong intentional stance. However, the focus of this paper is primarily concerned with the results of detailed user evaluations conducted on this system. Within the literature, comprehensive evaluations of mobile context-sensitive systems are sparse and therefore, this paper seeks, in part, to address this deficiency
Essays on Poverty and Wellbeing
Although economic growth has brought significant improvements in the standard of living in the UK over recent decades, there are still individuals living in poverty. Furthermore poverty in the UK is expected to rise. Although monetary poverty has wide ranging impacts such as poor health, low educational attainment and employability and reduced life expectancy, it does not (in the form of a poverty line at 60% of the median equivalised household income) appear to have an impact on wellbeing when the threshold was tested. Instead, multidimensional poverty – that purported by the Capabilities Approach – is a more individually relevant measure of poverty. Using a list, developed by Nussbaum, of core capabilities seen as essential for human life, capability measures were taken from the British Household Panel Survey. In analysis, some are found to be significant determinants of wellbeing, individually and in sum. Furthermore, individuals within the dataset experience loss aversion to capabilities. This thesis concludes that poverty measurement should be meaningful at the individual level, and to that aim, the Capabilities Approach provides a richer and more relevant evaluation of what poverty really means
Narrowing the wingless-2 mutation to a 227Â kb candidate region on chicken chromosome 12.
Wingless-2 (wg-2) is an autosomal recessive mutation in chicken that results in an embryonic lethal condition. Affected individuals exhibit a multisystem syndrome characterized by absent wings, truncated legs, and craniofacial, kidney, and feather malformations. Previously, work focused on phenotype description, establishing the autosomal recessive pattern of Mendelian inheritance and placing the mutation on an inbred genetic background to create the congenic line UCD Wingless-2.331. The research described in this paper employed the complementary tools of breeding, genetics, and genomics to map the chromosomal location of the mutation and successively narrow the size of the region for analysis of the causative element. Specifically, the wg-2 mutation was initially mapped to a 7 Mb region of chromosome 12 using an Illumina 3Â K SNP array. Subsequent SNP genotyping and exon sequencing combined with analysis from improved genome assemblies narrowed the region of interest to a maximum size of 227Â kb. Within this region, 3 validated and 3 predicted candidate genes are found, and these are described. The wg-2 mutation is a valuable resource to contribute to an improved understanding of the developmental pathways involved in chicken and avian limb development as well as serving as a model for human development, as the resulting syndrome shares features with human congenital disorders
