Kant's argumentation in the scholia to theorem VI in “Nova dilucidatio”: T. Pinder and J. Schmucker’s interpretations
No full textThis article considers Kant’s objection to the ontological argument in his early work “A New Elucidation of the First Principles of Metaphysical Cognition”. The alternative interpretations of Kant’s argumentation offered by T. Pinder and J. Schmucker are discussed. The author comes to the conclusion that none of these interpretations has advantages over the traditional one

A Case Study of the Population Ecology of a Topmouth Gudgeon (Pseudorasbora parva) Population in the UK and the Implication for Native Fish Communities
No full text1. The topmouth gudgeon Pseudorasbora parva is a small Asian cyprinid species that has proved invasive throughout many European countries. Following an initial introduction into the wild in 1996, the species is now proving invasive in the UK, with at least 25 infested waters in England and Wales, of which 10 are known to have direct connection to a major river catchment.
2. To demonstrate the threat of P. parva to fisheries in the UK, a case study is presented on a lake located in the Lake District of England where the species was introduced in 2000. The species rapidly established a breeding population that, by 2003, was the dominant species in size classes <70 mm. In 2004, they were the only species in the lake that produced young-of-the-year.
3. Individual P. parva adopted the reproductive tactics of early maturity, multiple spawning, male dominance and male nest guarding; sexual dimorphism was manifested in larger body size of males. These traits were in contrast to the resident, native species of the lake, including roach Rutilus rutilus and gudgeon Gobio gobio, which adopted traits of later maturity and single spawning.
4. This case study, therefore, revealed relatively rapid establishment of a P. parva population, their subsequent numerical dominance of the fish community, and the impediment of the recruitment of native fish. The implications for UK fisheries are concerning: should P. parva continue to disperse and individuals adopt similar traits as those in this case study, there may be few waters immune from their invasion, numerical dominance and subsequent impacts
Autofiction as feminist practice and the significance of art in how should a person be? and motherhood
No full textThis thesis examines two novels by the Canadian author Sheila Heti, How Should a Person Be? and Motherhood, through a feminist theoretical lens established in Simone de Beauvoir’s The Second Sex, Monique Wittig’s essay “One Is Not Born a Woman,” and Judith Butler’s Gender Trouble. The thesis argues that in Heti’s novels art is important to a woman’s self-exploration. To be exact, the undefined conventions of the autofictional genre parallel the freedom one is given through the process of “making art,” which ultimately disrupts gendered ideals of womanhood and femininity.Chapter One establishes the theoretical framework for the discussion of genre and gender by detailing how the works of feminist theorists Beauvoir, Wittig, and Butler lend themselves to the gendered reception of life writing. Chapter Two examines Heti’s How Should a Person Be? and uses the theoretical argument in Chapter One to ground its argument that the process of “making art” is more suitable than “using art” and that the malleable form of autofiction enables self-discovery of femininity and art for both the fictional character Sheila and the author Heti. Finally, Chapter Three analyzes Motherhood, illuminating the significance Heti finds in actively engaging in artistic media that reinforce the creative process and support the expansion of the limits of pre-determined feminine identity.</p
Life Between the Highways: Living with Traffic Noise in Suburban Copenhagen
No full textThis thesis explores what it is like to live with the sound of highway traffic as a constant aural presence in Mørkhøj, a suburb of Copenhagen, Denmark, that lies between two highways. In light of rising noise levels and mounting evidence that noise from traffic and other sources causes increased risks of physical health problems, abating noise is increasingly seen as an urgent urban planning problem. Noise is handled by acoustic engineers, who’s positivist, specialized and technical approaches do not deal with the lived realiDes of noise-affected citizens. This thesis represents an alternative to this approach by taking a qualitative, sensory ethnographic approach to the experience of noise. Drawing on communication theory, phenomenology and practice theory, the study finds that the perception and everyday experience of traffic noise is contingent on a complex interplay of embodied listening practices and aurally mediated information, everyday practice routines, and socially structured life circumstances. By integrating these social and lived dimensions of noise into sonic urban planning work, it is the opinion of the author that future noise-related urban planning interventions may be beMer tailored to the specific needs and problems of noise- affected citizens

Preliminary studies developing methods for the control of Chrysomya putoria, the African latrine fly, in pit latrines in The Gambia.
No full textOBJECTIVE: To explore ways of controlling Chrysomya putoria, the African latrine fly, in pit latrines. As pit latrines are a major source of these flies, eliminating these important breeding sites is likely to reduce village fly populations, and may reduce the spread of diarrhoeal pathogens. METHODS: We treated 24 latrines in a Gambian village: six each with (i) pyriproxyfen, an insect juvenile hormone mimic formulated as Sumilarv(®) 0.5 G, a 0.5% pyriproxyfen granule, (ii) expanded polystyrene beads (EPB), (iii) local soap or (iv) no treatment as controls. Flies were collected using exit traps placed over the drop holes, weekly for five weeks. In a separate study, we tested whether latrines also function as efficient flytraps using the faecal odours as attractants. We constructed six pit latrines each with a built-in flytrap and tested their catching efficiency compared to six fish-baited box traps positioned 10 m from the latrine. Focus group discussions conducted afterwards assessed the acceptability of the flytrap latrines. RESULTS: Numbers of emerging C. putoria were reduced by 96.0% (95% CIs: 94.5-97.2%) 4-5 weeks after treatment with pyriproxyfen; by 64.2% (95% CIs: 51.8-73.5%) after treatment with local soap; by 41.3% (95% CIs = 24.0-54.7%) after treatment with EPB 3-5 weeks after treatment. Flytraps placed on latrines collected C. putoria and were deemed acceptable to local communities. CONCLUSIONS: Sumilarv 0.5 G shows promise as a chemical control agent, whilst odour-baited latrine traps may prove a useful method of non-chemical fly control. Both methods warrant further development to reduce fly production from pit latrines. A combination of interventions may prove effective for the control of latrine flies and the diseases they transmit
Biological surveillance of chalk-streams
No full textAn article reviewing the methods of biological surveillance of chalk-streams developed and commonly used at that time, with a focus on their application to the River Frome catchment in Dorset. In evaluating the surveillance methods, the author looks at sampling methods (including cores and kick-sampling), the level of identification of macroinvertebrates, and temporal and spatial variations. Responses of indices to organic pollution are also discussed. A number of accompanying figures are also included
