The words beneath the sand: an examination of the works of three Virgin Islands poets, Cyril Creque, J. P. Gimenez, and J. Antonio Jarvis, 1995
No full textThis study is an excavation and examination of the works of Virgin Islands poets, Cyril Creque, I. P. Gimenez, and Antonio Jarvis, who wrote in the first half of the twentieth century. It looks at the historical and literary context that fostered them and provides a thorough study of one aspect of each man's poetry. In particular Creque's Romanticism is examined, as are Gimenez's vernacular poems, and Jarvis' dual consciousness. All three are examined from the perspective of the tensions created by their being products of the United States Virgin Islands, a territory at once Caribbean and American. The study set out to refute the assertions of critics that Virgin Islands poets were mere imitators of the European style. What has been revealed is a rich tapestry of original imagery and language, reflective of the Virgin Islands unique history and culture. A thorough examination of selected poems of each writer was conducted, as was research on each writer. This research was supported by available data and to a significant extent by information gathered from interviews with persons who knew the subjects of the study. This dissertation is, most likely, the first comprehensive critical work on Virgin Islands poetry and on Creque, Gimenez, and Jarvis. As such it will be useful to scholars interested in the literature of the Virgin Islands and also of the Caribbean and the United States of which the territory is a part. It verifies, not only the presence of a poetic heritage, but testifies to its quality as well as its significance in the two poetic traditions of which it is a part

Comparing Mediated and Unmediated Agent-Based Negotiation in Wi-Fi Channel Assignment
No full textChannel allocation in dense Wi-Fi networks is a complex problem due to its nonlinear and exponentially sized solution space. Negotiating over this domain is a challenge, since it is difficult to estimate opponent’s utility. Based on our previous work in mediated techniques, we propose the first two fully-distributed multi-agent negotiations for Wi-Fi channel assignment. Both of them use a simulated annealing sampling process and a noisy model graph estimation. One is designed for Alternating Offers protocols, while the other uses the novel Multiple Offers Protocol for Multilateral Negotiations with Partial Consensus (MOPaC), with experimental promising features for our particular domain. Our experiments compare both proposals against their mediated counterparts, showing similar results on social welfare, Nash product and fairness, but improving privacy and communication overhead.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Interactive Intelligenc
Sustainable Cities and Society / A new analytical tool for a more deliberate implementation of Sustainable Drainage Systems
No full textThis paper presents a new analytical tool for a more deliberate qualitative assessment of and guidance for the way Sustainable Drainage Systems (SuDS) are governed and technically implemented. It is the result of a combination of concepts from various alternative “sustainability” approaches and provides for the first time a set of detailed but not exhaustive aspects and sub-aspects that are critical for holistic implementation. A wide range of topics relevant for the attainment of radical change are embraced that had been rarely simultaneously considered in practice and research until now. Analyses at neighbourhood level in the solarCity (Linz, Austria) and Monges-Croix du Sud (Cornebarrieu, France), where SuDS have been comprehensively deployed, demonstrate the suitability of the tool for the provision of a more holistic perspective and direction for further change. Both projects represent the accomplishment of important steps towards sustainable stormwater management, but wider perspectives are required if the positive effects achieved are to be extended. Efforts have been made to understand the bio-physical traits of place prior to design and subsequently fulfil some technical demands, but reticence remains to: a) explore “closer to nature” solutions and transformative social considerations, and b) enter a continuous cycle of co-evolution.Marc Gimenez-Maranges, Jürgen Breuste, Angela Ho
Déterminants de la survie et de la dispersion de reproduction par une approche Capture-Marquage-Recapture chez l’Hirondelle bicolore au Québec.
No full textEn Amérique du Nord, la superficie des monocultures utilisatrices d’intrants tels que des fertilisants et des pesticides couvre aujourd’hui 85 % des surfaces agricoles et autant de pâturages ont disparus en 50 ans afin de répondre aux besoins de l’Homme. Ces changements d’usage des terres ont profondément transformé le paysage et altéré la biodiversité des agro-écosystèmes. Parmi les espèces d’oiseaux champêtres, les insectivores aériens tels l’Hirondelle bicolore, Tachycineta bicolor, ici étudiée, présentent un fort taux de déclin des effectifs, reflétant probablement une dégradation des agro-écosystèmes. Les mécanismes biologiques à l’origine de ce déclin sont encore méconnus ainsi que les patrons de dispersion chez les passereaux migrateurs. Le présent travail vise à étudier les effets environnementaux sur les traits individuels (survie et succès reproducteur) et la dispersion de reproduction (probabilité de disperser et taux d’occupation des sites de reproduction) chez l’Hirondelle bicolore. Pour ce faire, 2200 reproducteurs et 8000 oisillons ont été bagués entre 2004 et 2013 et suivis en reproduction pendant 10 ans sur une aire d’étude au Sud du Québec, laquelle est composée de 40 sites et couvre une mosaïque de paysages agricoles hétérogènes. Le développement d’un nouveau modèle de capture-marquage-recapture, flexible d’utilisation, a permis de réduire les biais d’estimation des probabilités de survie et de dispersion de l’espèce. Cette approche a permis de tester l’effet de plusieurs variables en lien avec la qualité de l’habitat, l’information publique et les caractéristiques individuelles sur la variabilité des paramètres de dispersion, de survie et de succès reproducteur au niveau individuel. Les milieux cultivés intensivement associés à la présence du Moineau domestique, Passer domesticus, un compétiteur pour les cavités de reproduction, diminuaient au maximum de 19 % la survie des mâles. Les femelles étaient quant à elles affectées par le coût de la reproduction, qui était d’autant plus grand en milieu intensif qu’il y avait une présence de moineaux et une disponibilité moindre en ressources alimentaires. Pour autant, la décision de disperser n’était pas affectée par les conditions environnementales que ce soit par la présence de compétiteurs ou la qualité du milieu, et ne dépassait pas les 4 % chez les mâles. Les femelles dispersant jusqu’à 14 fois plus s’appuyaient sur leur expérience personnelle pour décider de disperser. Un échec de reproduction augmentait jusqu’à 7 fois la probabilité de disperser et pour la première fois chez une espèce à courte durée de vie, nous avons montré que la probabilité de disperser était augmentée l’année suivant une première dispersion. Ces patrons de dispersion étaient stables dans le temps. La dispersion semblait donc être un processus coûteux, comparé à la fidélité au site, qui apparaissait comme un phénotype minoritaire dans la population. Elle répondait à des conditions défavorables de reproduction. Enfin, ce travail montre l’utilisation de l’information publique dans la décision de s’établir sur un site généralement fortement dense et productif en jeunes l’année précédente et ce, une fois que la décision de disperser est amorcée. La présence de moineaux et la forte proportion de cultures intensives dans un rayon proche participaient également à ll‘évitement des sites lors de l’établissement. D’après ces résultats, le milieu intensif contribuerait au déclin de l’Hirondelle bicolore.In North America, monoculture areas using high inputs of fertilizers and pesticides cover 85 % of agricultural lands, and as many pastures disappeared in the past 20 years to satisfy human food needs. These land-use changes have deeply transformed landscapes and altered the biodiversity of agro-ecosystems. Among farmland birds, aerial insectivores such as Tree Swallow, Tachycineta bicolor, studied here show a high rate of decline in their abundance, partly reflecting the degradation of agro-ecosystems where they breed. Biological mechanisms leading to the decline and dispersal patterns in migratory passerines are still poorly known. The present work quantifies the environmental effects on Tree Swallow individual traits (survival, reproductive success) and breeding dispersal (probability to disperse and occupation rates of breeding sites). Between 2004 and 2013, 2200 breeders and 8000 chicks were ringed and monitored during 10 breeding seasons on a study area composed of 40 sites and covering a mosaic of heterogeneous agricultural landscapes in southern Québec. The development of a new, flexible capture-mark-recapture model has reduced estimate bias of survival and dispersal probabilities of Tree Swallows. This approach allowed to assess the effect of several variables linked to habitat quality, public information and individual characteristics on dispersal, survival and reproductive success parameters of individuals. Within intensively cultivated landscapes associated to the presence of a nest site competitor, the House sparrow, Passer domesticus, male survival is up to 19 % lower. Females were affected by the cost of reproduction, especially in intensive landscapes where House sparrows and found and where food resources and nest site appear limited. Dispersal probability was not affected by environmental conditions either through the presence of House sparrows or habitat quality, and was restricted to 4 % in males. Females, which dispersed up to 14 times more than males, based their decision on their personal experience. Breeding failure increased up to 7 times the probability to disperse and for the first time in a short-lived species, I show that dispersal likelihood increased if the individual had dispersed in the previous year. These dispersal patterns were stable in time. Dispersal appeared as a costly process compared to site fidelity and was a minority phenotype in the population. It appeared an answer to unfavorable condition for reproduction. Finally, this work shows the use of public information (partners density, fledglings productivity the previous year) on the decision to settle on a site and this, after the dispersal decision had been initiated. The presence of House sparrows and the proportion of intensive areas near nest boxes were used as information to select a breeding site. Based on these findings, agricultural intensification likely plays a role in the decline of Tree swallow populations
