Utilisation de systèmes d'information géographique pour l'évaluation des risques liés à la dégradation du pergélisol. Étude de cas : Tasiujaq, Nunavik, Québec

Les régions nordiques à pergélisol seront largement affectées par l'augmentation prévue des températures. Un nombre croissant d’infrastructures qui étaient autrefois construites avec confiance sur des sols gelés en permanence commencent déjà à montrer des signes de détérioration. Les processus engendrés par la dégradation du pergélisol peuvent causer des dommages importants aux infrastructures et entrainer des coûts élevés de réparation. En conséquence, le contexte climatique actuel commande que la planification des projets dans les régions nordiques s’effectue en tenant compte des impacts potentiels de la dégradation du pergélisol. Ce mémoire porte sur l’utilisation de systèmes d’information géographique (SIG) appliqués à l’évaluation du potentiel d’aménagement des territoires situés en milieu de pergélisol. En utilisant une approche SIG, l’objectif est d’élaborer une méthodologie permettant de produire des cartes d'évaluation des risques afin d’aider les collectivités nordiques à mieux planifier leur environnement bâti. Une analyse multi-échelle du paysage est nécessaire et doit inclure l'étude des dépôts de surface, la topographie, ainsi que les conditions du pergélisol, la végétation et les conditions de drainage. La complexité de l'ensemble des interactions qui façonnent le paysage est telle qu'il est pratiquement impossible de rendre compte de chacun d'eux ou de prévoir avec certitude la réponse du système suite à des perturbations. Ce mémoire présente aussi certaines limites liées à l’utilisation des SIG dans ce contexte spécifique et explore une méthode innovatrice permettant de quantifier l'incertitude dans les cartes d'évaluation des risques.

Consumption of Bias and Reptition as a Revisionary Strategies in Palace of the Peacock and in the Thought of Wilson Harris

Wilson Harris créée dans son roman Le palace du paon un espace de transformation intellectuelle d’une nature inédite. Cet espace se confond avec la matrice narrative de son roman. Celle-ci permet la génèse de l’identité guyanaise, non pas à partir des vestiges pré-coloniaux, ni grâce aux récits des historiens des vainqueurs mais avec des ingrédients philosophiques et littéraires de nature à transformer l’étoffe même de notre imaginaire et énergie créative. Il utilise pour ce faire la répétition comme stratégie narrative permettant de rompre la linéarité chronologique qui joint passé, présent et avenir. Ainsi faisant, il déjoue toutes les attentes de ses lecteurs les habituant ainsi à ce que Derrida appelle la logique spectrale qui permet l’influence mutuelle entre passé et présent. Ce travail est l’exploration des mécanismes de ce lâcher prise imaginatif mais aussi de toutes les voix qui répètent, à travers le temps et les continents, cet appel à l’hospitalité inconditionnelle envers l’Autre, c'est-à-dire une ouverture envers le paradoxal, le multiple, le différent en soi et en dehors de soi.

Design of a Knowledge-Based Geographic Information System

A GIS has been designed with limited Functionalities; but with a novel approach in Aits design. The spatial data model adopted in the design of KBGIS is the unlinked vector model. Each map entity is encoded separately in vector fonn, without referencing any of its neighbouring entities. Spatial relations, in other words, are not encoded. This approach is adequate for routine analysis of geographic data represented on a planar map, and their display (Pages 105-106). Even though spatial relations are not encoded explicitly, they can be extracted through the specially designed queries. This work was undertaken as an experiment to study the feasibility of developing a GIS using a knowledge base in place of a relational database. The source of input spatial data was accurate sheet maps that were manually digitised. Each identifiable geographic primitive was represented as a distinct object, with its spatial properties and attributes defined. Composite spatial objects, made up of primitive objects, were formulated, based on production rules defining such compositions. The facts and rules were then organised into a production system, using OPS5

Biochar improves fertility of a clay soil in the Brazilian Savannah: short term effects and impact on rice yield

The objective of this study was to report single season effects of wood biochar (char) application coupled with N fertilization on soil chemical properties, aerobic rice growth and grain yield in a clayey Rhodic Ferralsol in the Brazilian Savannah. Char application effected an increase in soil pH, K, Ca, Mg, CEC, Mn and nitrate while decreasing Al content and potential acidity of soils. No distinct effect of char application on grain yield of aerobic rice was observed. We believe that soil properties impacted by char application were inconsequential for rice yields because neither water, low pH, nor the availability of K or P were limiting factors for rice production. Rate of char above 16 Mg ha^(−1) reduced leaf area index and total shoot dry matter by 72 days after sowing. The number of panicles infected by rice blast decreased with increasing char rate. Increased dry matter beyond the remobilization capacity of the crop, and high number of panicles infected by rice blast were the likely cause of the lower grain yield observed when more than 60 kg N ha^(−1) was applied. The optimal rate of N was 46 kg ha^(−1) and resulted in a rice grain yield above 3 Mg ha^(−1).

Agricultural Production and Yield Estimation: Two distinctive aspects of Brazilian Agriculture and a perspective on world food problems

Brazil has been increasing its importance in agricultural markets. The reasons are well known to be the relative abundance of land, the increasing technology used in crops, and the development of the agribusiness sector which allow for a fast response to price stimuli. The elasticity of acreage response to increases in expected return is estimated for Soybeans in a dynamic (long term) error correction model. Regarding yield patterns, a large variation in the yearly rates of growth in yield is observed, climate being probably the main source of this variation which result in ‘good’ and ‘bad’ years. In South America, special attention should be given to the El Niño and La Niña phenomena, both said to have important effects on rainfalls patterns and consequently in yield. The influence on El Niño and La Niña in historical data is examined and some ways of estimating the impact of climate on yield of Soybean and Corn markets are proposed. Possible implications of climate change may apply.

The Brazilian Zero Hunger social program implications in achieving sustainable development

This article aims to analyse the progress taken by Brazil towards the accomplishment of a sustainable development, mainly highlighting the success of the Zero Hunger social programme in achieving the elimination of starvation. As one of the essential pillars to the sustainable development, the State’s social performance demands actions directed to the elimination of extreme poverty and hunger, establishing a basis for equitable growth. It is necessary to clarify the juridical and constitutional framework of Brazil, aiming to emphasise the Zero Hunger importance in achieving the Brazilian Republic’s goals and reaching an international pattern on sustainable development. Also, it will be stressed that the international order influences Brazilian domestic law and is one of the main aspects for the Zero Hunger program development.

How do consumers perceive organic food from different geographic origins? Evidence from Hong Kong and Shanghai

The objective of this paper is to understand how Chinese consumers perceive certified organic food, especially the differences between locally and nationally produced organic food compared to food produced overseas. In 2012, a consumer survey was conducted at supermarkets in Hong Kong and Shanghai (N=245). Participants were asked for their perception on four different food origins: locally produced organic food, organic food from China, imported organic food, and locally produced conventional food. Consumers in Hong Kong had a positive attitude towards local organic food and imported organic food. However, they were sceptical about organic food from China, in particular regarding chemical residues and the trustworthiness of producers. Consumers in Shanghai, in contrast, had a positive attitude towards all three tested geographical origins of organic food. Overall, the results suggest that it is challenging for marketers to promote and boost the sales of China-produced organic food in China. Better communication is essential to convince consumers that organic food from China is of similar quality as organic food produced elsewhere.

Incidencia de la Cuenca Amazónica en las relaciones colombo-brasileñas, en materia de seguridad. Periodo 2006-2011

La Amazonía fue por mucho tiempo tan solo un gran espacio selvático, de difícil penetración, con un clima de gran humedad, lejano de los centros de poder y por lo tanto, relegado a un segundo plano en las políticas nacionales. Sin embargo, la región amazónica ha cambiado profundamente en las últimas décadas, lo que a su vez ha generado una profunda transformación en las políticas dirigidas hacia dicho espacio, la atención internacional que la cuenca recibe y las dinámicas e intereses nacionales e internacionales que alrededor de ella se encuentran. Dicha transformación llevó a una multiplicación y a una diversificación de las dinámicas de seguridad e inseguridad en la región y en el continente, modificando las relaciones entre actores internacionales con intereses en la región.

Turing’s imitation game and human thought

In 1950, the English mathematician Alan Mathison Turing proposed the basis of what some authors consider the test that a machine must pass to establish that it can think. This test is basically a game; nevertheless, it has had great infl uence in the development of the theories of the mind performance. The game specifications and some of its repercussions in the conception of thinking, the consciousness and the human will, will be ramifications of the path that will take us through the beginning of the artificial intelligence, passing along some of its singular manifestations, to culminate in the posing of certain restrictions of its fundaments.

Familiar characteristics and received familiar support among Brazilian adolescents with and without pregnancy experience

The present paper aimed to investigate how adolescents with pregnancy experience evaluate received support from their families in comparison with an adolescent group without pregnancy experience. 452 low income adolescents, both sex, aged 14 to 19 years old answered to a questionnaire. The results revealed that more girls (64.2 %) than boys (35.8 %) declared pregnancy experience, ?2 (2, n = 2617) = 48.32, p < .001. Moreover, it was observed that the group with pregnancy experience, in comparison with other group, revealed more perception on the family relationships safety, t (408) = -3.0, p < .01; mutual respect among family members in their homes, t (392) = -2.3, p < .05; and received stronger general support from their family, t (397) = -1,3, p < .05. These results are discussed.
