Abstract:
Clustering is the art of locating patterns in large data sets. It is an active research area that provides value to scientific as well as business applications. There are some challenges that face practical clustering including: identifying clusters of arbitrary shapes, sensitivity to the order of input, dynamic determination of the number of clusters, outlier handling, high dependency on user-defined parameters, processing speed of massive data sets, and the potential to fall into sub-optimal solutions. Many studies that were conducted in the realm of clustering have addressed some of these c

Abstract:
Population structure, gene flow and dispersal are some of the most commonly estimated population parameters in population genetics, evolutionary biology and conservation genetics. The primary aim of thesis is to test the precision and accuracy of genetic estimates of population structure, gene flow and dispersal. The controlled replicated Drosophila melanogaster experiments of known effective population size (Ne = 14.3) and dispersal rate (m = 0.0025 - 0.04) all adhered to Wright??s demographic island model. Three statistical approaches were empirically tested: 1) the conversion of population

Abstract:
This study deals with the trend of male bodybuilding in Korea and investigates the motivations and aesthetic ideals of Korean male bodybuilders. The author of the study uses the few hitherto academic research works on the subject and tries to give an overview of the history of Korean bodybuilding. Besides, the author has conducted a digital survey in order to collect answers from Korean male bodybuilders about their motivations, aesthetic ideals, etc. The aesthetic ideals of the bodybuilders are then compared to the male aesthetic ideals of modern Korean society and also discussed in relation

Abstract:
The typical intermediate morphology of hybrids may result in their failure to utilize the same niches as their parents. However, the fitness consequences of the potentially intermediate life-history traits of hybrids have been given less scientific attention. In this study I aimed to investigate how life-history divergence in parental species affects the relative fitness of nestling hybrids resulting from crosses between collared (Ficedula albicollis) and pied flycatchers (F. hypoleuca). Previous studies showed that collared flycatcher nestlings beg more intensively and grow faster under good

Syfte: Denna studie ämnar beskriva och analysera organisationsformer och ledarskap inom svensk golfverksamhet. Svensk golf är speciell eftersom den både finns i ideell form inom Riksidrottsförbundets ramar, i kombination med ett aktiebolag och som rent kommersiell verksamhet. Svensk idrottsverksamhet lägger högt fokus på samhällsvärde, samtidigt som organisationer behöver hantera en komplex ekonomisk verksamhet. Oavsett verksamhetsform kan friktion uppstå och organisationer med multipla institutionella logiker behöver hantera de krav som skapas.   Metod: Studien utfördes genom intervjuer med n

Abstract:
Studies were conducted in 1996 through 1999 to: (1) evaluate the responses of one imidazolinone (IMI)-susceptible (S) and four -resistant (R1, R2, R3, and R4) smooth pigweed populations to various acetolactate synthase (ALS)-inhibiting herbicides, (2) determine the mechanism of resistance, and (3) evaluate the relative growth and competitiveness of each population. Field studies were conducted in 1996 near Marion, MD, in a field with a history of repeated imazaquin use. Smooth pigweed control with IMI herbicides was < 8 percent, but control with sulfonylurea (SU) herbicides ranged from 73 to 9

Introgression of genes from crops into ruderal populations is a multi-step process requiring sympatry, synchronous flowering, chromosomal compatibility, successful pollination and development of the zygote, germination, establishment and reproduction of hybrid progeny. The goal of this thesis was to generate data on as many steps in this process as possible and integrate them into a predictive statistical model to estimate the likelihood of successful introgression under a range of scenarios.

Abstract:
This thesis evaluates the Children’s Fitness Tax Credit and similar credits to determine whether they are suitable to increase physical activity levels in Canada. It begins by reviewing the literature on physical activity to establish that increasing physical activity is a worthy public policy goal. It then reviews the literature on tax expenditures and health behaviour interventions to provide information in order to evaluate the credits. The credits are then described and their stated purpose is discussed. This description establishes how quickly the credits expanded from one small credit to
