Governments and the Decentralization

The Purpose of This Article Is to Show How Costs and Benefits of Geographical Decentralization of R&D Can Be Identified and Compared. the Benefits for the Region That Receives R&D Activities Are Studied in Section 1. They Stem From the Short-Run Multiplier Effect, the Amelioration of Human Capital and the Possible Modernization of the Local Industrial Structure. on the Cost Side Examined in Section 2, the Observable Impacts of the Decentralization of R&D Concern the Loss of Returns to Scale and of the Production of the R&D Output. It Is Shown, in Section 3, That the Flows of Costs and Benefits Must Be Discounted by the Social Cost of Capital. the Main Conclusion of This Article Is That the Decentralization of R&D in a Large Sparsely Populated Country Entails Social Cost and Would Weaken Its Competitive Position in World Commerce. on the Other Hand, the Issue of Decentralization Is More Crucial for Small Countries (In Terms of Population and Economic Size) Than for Large Ones, Like the U.S., Where Critical Masses of Research Efforts Cna Be Simulataneously Attained in Many Fields and in Many Places.

L’archivage numérique des projets « Europan » comme situation d’analyse scientifique du concours d’idées en architecture

Il existe somme toute peu de théories du projet offrant une modélisation construite à partir de la complexité et de la diversité du projet d’architecture. Pourtant,certaines situations rassemblant parfois plusieurs dizaines de projets s’offrent d’elles-mêmes comme des situations comparatives et expérimentales : les concours d’architecture, d’urbanisme et de paysage. Le Laboratoire d’étude de l’architecture potentielle de l’Université de Montréal (Aménagement), après avoir développé un système d’archivage numérique des concours canadiens, a entrepris, avec le soutien du Groupement d’intérêt public « Europe des projets architecturaux et urbains », de développer la base de données documentaire des concours d’idées Europan. Au-delà des questions d’archivage numérique, se profilent clairement des possibilités de théorisation s’appuyant sur les logiques d’une base de données, en particulier sur la constitution du diagramme entités et relations, modélisation indispensable à sa traduction informatique. Cette recherche entreprend une première mise à jour de ces éléments conceptuels et tend à montrer que la base de données est un véritable modèle théorique du projet ouvrant sur de nouvelles avenues de recherche et de connaissance.

Attitudes stigmatisantes envers les personnes vivant avec le VIH : développement et validation d’un instrument de mesure intégrant un dispositif participatif

Contexte : De manière générale, on considère que le processus de validation d’un instrument de mesure porte sur la validité et la fiabilité. Or, la nature dynamique et évolutive de certaines problématiques, comme la stigmatisation des personnes vivant avec le VIH (PVVIH), laisse croire qu’il est particulièrement important de réinvestir rapidement dans la pratique, les résultats produits par les mesures ainsi validées. Objectifs : La présente thèse vise à développer et valider une échelle de mesure des attitudes stigmatisantes envers les PVVIH en intégrant un dispositif participatif. La thèse utilise en partie les données d’une enquête de surveillance des attitudes envers les PVVIH au Québec, elle comporte trois études qui répondent aux trois objectifs spécifiques suivants : (1) valider la version révisée d’un instrument de mesure des attitudes favorables à la stigmatisation dans la population générale du Québec envers les PVVIH; (2) analyser la relation entre la mesure des attitudes favorables à la stigmatisation et le recours au dépistage du VIH dans la population générale du Québec; (3) décrire et analyser les processus de circulation et d’utilisation des connaissances produites par l’instrument de mesure dans les réseaux professionnels des membres d’un comité consultatif. Méthodes : Un comité consultatif réunissant plusieurs partenaires issus de différents milieux a été constitué dès l’obtention de la subvention. Il a été consulté et informé avant, pendant et après l’enquête téléphonique populationnelle (n=1500) ayant permis de colliger les données. L’Échelle des Attitudes Stigmatisantes envers les Personnes Vivant avec le VIH (EASE-PVVIH) a été validée au moyen de plusieurs analyses psychométriques : analyses factorielles exploratoires et confirmatives, corrélations, régression linéaire multiple, test-t, tests d’hypothèses d’invariance de la structure factorielle et alphas de Cronbach (objectif 1). L’association entre les attitudes favorables à la stigmatisation et le recours au dépistage du VIH a été testée à l’aide de régressions logistiques hiérarchiques (objectif 2). Quant aux processus de circulation et d’utilisation des connaissances dans les réseaux professionnels, ils ont été analysés au moyen d’une étude de cas rétrospective (objectif 3). Résultats : Les analyses ont révélé trois résultats importants. Premièrement, d’un point de vue psychométrique, l’EASE-PVVIH est un outil fiable et valide pour mesurer les attitudes stigmatisantes envers les personnes vivant avec le VIH. Deuxièmement, sous une certaine forme caractérisée par l’inquiétude éprouvée lors de rencontres occasionnelles, les attitudes stigmatisantes par rapport aux personnes vivant avec le VIH semblent nuire au recours au test de dépistage dans la population générale au Québec. Troisièmement, un dispositif participatif en particulier, soit un comité consultatif, semble être un moyen pour favoriser le réinvestissement rapide et étendre la portée des résultats produits par la recherche dans des actions concrètes de santé publique. Conclusion : Ces résultats mettent en lumière la portée d’un dispositif participatif pour la validation d’instrument de mesure. L’arrimage entre les préoccupations scientifiques et pratiques apparaît être une avenue prometteuse pour améliorer la qualité et la pertinence sociale des données produites par les mesures.

L'oeuvre au service de la traduction : l'écriture vianesque, une invitation à la traduction créative

Stanley Chapman n’est pas un traducteur ni même un écrivain très connu. Le volume de ses écrits originaux, qui sont d’ailleurs difficiles voire impossibles à trouver, et des traductions à son actif reste mince. Peut-être serait-il même passé complètement inaperçu, sauf bien sûr chez ses compères du Collège de ’Pataphysique, de l’Oulipo et de l’Outrapo, s’il n’avait pas traduit deux romans phares de l’écrivain français Boris Vian: L’Écume des jours et L’Arrache-coeur. La prose singulière de Vian l’aurait-elle incité à passer à l’acte d’écriture qui trouve justement sa source et se déploie dans l’acte du traduire ? Par ailleurs, les affinités intellectuelles que partageaient Vian et Chapman pourraient-elles aussi être en cause dans cette expérience du traduire ? Henri Meschonnic et Antoine Berman nous informent que la critique de la traduction a le pouvoir de révéler le rapport intime entre la pensée, l’écriture et la traduction. À partir de la « poétique du traduire » de Meschonnic et de « l’analytique de la traduction » de Berman, ce mémoire interroge en quoi Heartsnatcher, la traduction anglaise de L’Arrache-coeur, peut être considérée comme un acte de « traduire-écrire ». Étayée des notions de rythme et de signifiance, notre critique identifie les stratégies qui émergent de cette activité de création qu’est la traduction et par le fait même, révèle la manière particulière dont Stanley Chapman est parvenu à traduire L’Arrache-coeur.

La reintegración social y económica de los grupos armados ilegales en Colombia: reflexiones a partir de la trayectoria de nueve excombatientes

Esta investigación toma como marco general la Política de Reintegración Social y económica de personas y grupos alzados en armas en Colombia, en donde tras el estudio de las trayectorias en el conflicto de un grupo de 9 excombatientes, se aborda la relación existente entre los beneficios otorgados por dicha política y aquello que facilitó y motivó el ingreso, la permanencia y desmovilización de los grupos armados. Se presenta una caracterización e interpretación conceptual de las denominadas trayectorias en el conflicto, son establecidas relaciones y diferencias entre las organizaciones ilegales FARC y las AUC, se revisan las percepciones que frente a los beneficios del programa de reintegración tienen excombatientes y profesionales de la entidad que lidera dicho proceso y a partir de ello, es argumentada la incidencia que sobre el éxito de esta política tienen las características individuales y particulares, tanto de los excombatientes como de las organizaciones armadas ilegales.

Career journeys and turning points of senior female managers in small construction firms

There is under-representation of senior female managers within small construction firms in the United Kingdom. The position is denying the sector a valuable pool of labour to address acute knowledge and skill shortages. Grounded theory on the career progression of senior female managers in these firms is developed from biographical interviews. First, a turning point model which distinguishes the interplay between human agency and work/home structure is given. Second, four career development phases are identified. The career journeys are characterized by ad hoc decisions and opportunities which were not influenced by external policies aimed at improving the representation of women in construction. Third, the 'hidden', but potentially significant, contribution of women-owned small construction firms is noted. The key challenge for policy and practice is to balance these external approaches with recognition of the 'inside out' reality of the 'lived experiences' of female managers. To progress this agenda there is a need for: appropriate longitudinal statistical data to quantify the scale of senior female managers and owners of small construction firms over time; and, social construction and gendered organizational analysis research to develop a general discourse on gender difference with these firms.

Climate and more sustainable cities: climate information for improved planning and management of cities (producers/capabilities perspective)

In the last two decades substantial advances have been made in the understanding of the scientific basis of urban climates. These are reviewed here with attention to sustainability of cities, applications that use climate information, and scientific understanding in relation to measurements and modelling. Consideration is given from street (micro) scale to neighbourhood (local) to city and region (meso) scale. Those areas where improvements are needed in the next decade to ensure more sustainable cities are identified. High-priority recommendations are made in the following six strategic areas: observations, data, understanding, modelling, tools and education. These include the need for more operational urban measurement stations and networks; for an international data archive to aid translation of research findings into design tools, along with guidelines for different climate zones and land uses; to develop methods to analyse atmospheric data measured above complex urban surfaces; to improve short-range, high-resolution numerical prediction of weather, air quality and chemical dispersion through improved modelling of the biogeophysical features of the urban land surface; to improve education about urban meteorology; and to encourage communication across scientific disciplines at a range of spatial and temporal scales.

Patient and public involvement in healthcare quality improvement: how organizations can help patients and professionals to collaborate

Citizens across the world are increasingly called upon to participate in healthcare improvement. It is often unclear how this can be made to work in practice. This 4- year ethnography of a UK healthcare improvement initiative showed that patients used elements of organizational culture as resources to help them collaborate with healthcare professionals. The four elements were: (1) organizational emphasis on nonhierarchical, multidisciplinary collaboration; (2) organizational staff ability to model desired behaviours of recognition and respect; (3) commitment to rapid action, including quick translation of research into practice; and (4) the constant data collection and reflection process facilitated by improvement methods.

Evaluation of Red Colour Segmentation Algorithms in Traffic Signs Detection

Colour segmentation is the most commonly used method in road signs detection. Road sign contains several basic colours such as red, yellow, blue and white which depends on countries.The objective of this thesis is to do an evaluation of the four colour segmentation algorithms. Dynamic Threshold Algorithm, A Modification of de la Escalera’s Algorithm, the Fuzzy Colour Segmentation Algorithm and Shadow and Highlight Invariant Algorithm. The processing time and segmentation success rate as criteria are used to compare the performance of the four algorithms. And red colour is selected as the target colour to complete the comparison. All the testing images are selected from the Traffic Signs Database of Dalarna University [1] randomly according to the category. These road sign images are taken from a digital camera mounted in a moving car in Sweden.Experiments show that the Fuzzy Colour Segmentation Algorithm and Shadow and Highlight Invariant Algorithm are more accurate and stable to detect red colour of road signs. And the method could also be used in other colours analysis research. The yellow colour which is chosen to evaluate the performance of the four algorithms can reference Master Thesis of Yumei Liu.

Tradução e adaptação transcultural do instrumento de avaliação prenatal selfevaluation questionnaire

Introduction: The human gestation period is 40 weeks. This is the essential time for maternal psychosocial adaptation, in which there is the intense transformation of a life without offspring into a life with one or more children. The Pregnancy Self-Evaluation Questionnaire (PSEQ) has 79 items, subdivided into seven subcategories: acceptance of pregnancy, identification with the maternal role, well-being of mother and baby, preparing for labor, control in labor, relationship with the mother and the relationship with the partner. Objective: To translate and cross-culturally adapt the instrument PSEQ to be used with Brazilian women. Methods: It is a cross-sectional observational study. We followed some methodological steps to achieve the cross-cultural adaptation of this measuring instrument. They are: translation, synthesis, back translation, analysis of the committee of specialists and pre-test. Another questionnaire was applied to characterize the socio-demographic and clinical status of the pregnant women (n = 36). The descriptive statistics was gotten through the average, standard deviation (SD), absolute and relative frequency. The statistical test used for the analysis of the internal consistency was Cronbach's alpha coefficient, using SPSS version 17.0. Results: The volunteers had low socioeconomic status, average age of 25.1 years (± 5.52), and average gestational age of 25.9 weeks (± 8.11). 58.3% of these volunteers had not planned their current pregnancy. The pretest showed that 75% of pregnant women found the questionnaire easy to understand. There was an average of 76.9 (± 3.23) answered items among the participants. Regarding the instrument PSEQ, the identification with the maternal role was the subcategory which showed the highest average 24.8 (± 5.6), while the relationship with the mother had the lowest average 15.4 (± 7.7). The internal consistency ranged from 0.52-0.89. Conclusion: The translation and cross-cultural adaptation of the PSEQ to Portuguese language were carried out with methodological rigor and can be considered an instrument with good internal consistency

Systematic reviews showed insufficient evidence for clinical practice in 2004: What about in 2011? the next appeal for the evidence-based medicine age

Rationale and aim The aims of the Cochrane systematic reviews are to make readily available and up-to-date information for clinical practice, offering consistent evidence and straightforward recommendations. In 2004, we evaluated the conclusions from Cochrane systematic reviews of randomized controlled trials in terms of their recommendations for clinical practice and found that 47.83% of them had insufficient evidence for use in clinical practice. We proposed to reanalyze the reviews to evaluate whether this percentage had significantly decreased. Methods A cross-sectional study of systematic reviews published in the Cochrane Library (Issue 7, 2011) was conducted. We randomly selected reviews across all 52 Cochrane Collaborative Review Groups. Results We analyzed 1128 completed systematic reviews. Of these, 45.30% concluded that the interventions studied were likely to be beneficial, of which only 2.04% recommended no further research. In total, 45.04% of the reviews reported that the evidence did not support either benefit or harm, of which 0.8% did not recommend further studies and 44.24% recommended additional studies; the latter has decreased from our previous study with a difference of 3.59%. Conclusion Only a small number of the Cochrane collaboration's systematic reviews support clinical interventions with no need for additional research. A larger number of high-quality randomized clinical trials are necessary to change the 'insufficient evidence' scenario for clinical practice illustrated by the Cochrane database. It is recommended that we should produce higher-quality primary studies in active collaboration and consultation with global scholars and societies so that this can represent a major component of methodological advance in this context. © 2012 John Wiley & Sons Ltd.

O CME do município de Ananindeua na construção da política educacional: a busca pela participação social

O Estudo denominado o CME do Município de Ananindeua na Construção da Política Educacional: a busca pela participação social. Teve como objetivos: analisar como a participação da sociedade civil organizada por meio de seus diferentes representantes vem sendo construída no interior do Conselho Municipal de Educação na tentativa de construir uma política educacional com base nos princípios de democracia participativa; analisar como a participação da sociedade civil organizada vem sendo oportunizada na construção da política educacional por meio do CME/Ananindeua; analisar a atuação do CME na promoção de uma política educacional na busca pela promoção da participação social e analisar como vem sendo desenvolvida à relação do CME com os demais elementos que compõe o Sistema Municipal de Ensino na construção da política educacional. Análise Documental e Entrevistas semi-estruturadas foram os instrumentos utilizados para responder os objetivos explicitados. O tratamento dos dados foi possível através de análise de conteúdo (investigação bibliográfica) e análise das fontes primárias (Atas; Leis Decretos; Pareceres; Regimento Interno). Os resultados alcançados com a investigação nos levam a inferir que a participação social como princípio educativo no interior do CME em Ananindeua vem sendo construída de forma gradual, uma vez que a democratização da gestão educacional por meio da participação direta, tanto no chão da escola como nos outros elementos que compõem o sistema educacional é um processo que precisa ser construído cotidianamente no coletivo. No caso da participação da sociedade no CME através das diversas categorias representadas vem se constituindo um desafio, pois os conflitos, as tensões, correlações de forças, disputa de poder estão sempre presentes. Esse fato em algumas circunstâncias é positivo uma vez que também é possível a construção de política educacional em meio à diversidade de opiniões. As categorias da sociedade civil organizada e representada no CME apresentam diferentes graus de participação, algumas participam mais ativamente enquanto outras têm uma menor atuação no momento de reuniões de Câmara e Plenárias onde são debatidas e feitas as proposições no que tange a construção da política educacional em Ananindeua. A falta de formação teórica, pedagógica e política em alguns casos servem como fator que limita a participação social nas ações do CME.

Biologia pulpar: da agressão à reparação

The study of the dental pulp can be extended from factors related to its aggression to those related to new concepts of regeneration. The purpose of this compilation of studies is to present the evolution of a research subject from damage to repair. Innitially, studies will demonstrate the ability of dental procedures to generate heat and consequently affect the dental pulp. In sequence, studies will also present some effects of different pulp capping materials on dental pulp cells, related to the cytotoxicity of these materials and inflammatory potential. Finally, as the subject is emmerging and gaining importance in the literature, this compilation will present data from recent studies on the role of dental pulp progenitor cells in the regeneration and repair of dental pulp, as well as an alternative for a scaffold that could be used for clinical translation of research in the field. In summary, dentists must be aware of these different aspects and that the knowledge on factors and mechanisms involved in the aggression of the dental pulp can also serve as basis for understanding aspects for regeneration.
