Understandings of transnational families in debates on Migration and development

International migration sets in motion a range of significant transnational processes that connect countries and people. How migration interacts with development and how policies might promote and enhance such interactions have, since the turn of the millennium, gained attention on the international agenda. The recognition that transnational practices connect migrants and their families across sending and receiving societies forms part of this debate. The ways in which policy debate employs and understands transnational family ties nevertheless remain underexplored. This article sets out to discern the understandings of the family in two (often intermingled) debates concerned with transnational interactions: The largely state and policydriven discourse on the potential benefits of migration on economic development, and the largely academic transnational family literature focusing on issues of care and the micro-politics of gender and generation. Emphasizing the relation between diverse migration-development dynamics and specific family positions, we ask whether an analytical point of departure in respective transnational motherhood, fatherhood or childhood is linked to emphasizing certain outcomes. We conclude by sketching important strands of inclusions and exclusions of family matters in policy discourse and suggest ways to better integrate a transnational family perspective in global migration-development policy.

Temor, silencio y deliberación: la inhibición de la opinión en Tucídides

Tucídides es una de nuestras mejores fuentes de información para conocer la práctica argumentativa de la deliberación democrática. En este trabajo se analiza uno de los vicios que, según el historiador, haría su aparición en la escena política ateniense a la muerte de Pericles: la instrumentalización del miedo para obtener la victoria momentánea en la asamblea. El temor prudente, que fuera una arma periclea para conducir la deliberación racional en aras del bien común, habría desaparecido siendo sustituido por el amedrentamiento del rival, la calumnia, el obstruccionismo y la parálisis de la confrontación dialéctica. Instauradas en la ciudad la desconfianza y la sospecha de ocultación, los golpistas del 411 hallaron el terreno abonado para callar las voces contrarias y, gracias al silencio, instaurar el terror.

La congruence des valeurs : un facteur à considérer pour rehausser le leadership transformationnel et son efficacité ?

Les théories sous-tendant le leadership transformationnel suggèrent que la congruence des valeurs personnelles et organisationnelles est au cœur du fonctionnement du leadership transformationnel. Or, l’examen de cette proposition soulève certaines questions. Par exemple, il y a lieu de s’interroger quant à l’importance du type (subjective ou objective) et de la cible (équipe, organisation) de congruence considérés, du contenu des valeurs utilisées pour juger de la congruence, des contingences situationnelles modulant l’importance de la congruence, et du rôle de la congruence des valeurs des leaders eux-mêmes. Ainsi, afin d’enrichir les connaissances sur le rôle des valeurs en regard du leadership transformationnel, cette thèse propose trois articles dans lesquels ce rôle des valeurs et de leur congruence est abordé sous trois angles. Les données utilisées dans cette thèse proviennent d’une grande organisation canadienne, et des sous-ensembles de données sont créés pour répondre aux objectifs de chaque article. Le premier article s’intéresse aux liens qu’ont a) les valeurs personnelles des gestionnaires, b) les valeurs qu’ils perçoivent dans leur organisation et c) la congruence de ces deux ensemble de valeurs avec l’émission de comportements de leadership transformationnel tel que perçus par leurs subordonnés. Les résultats suggèrent que la congruence des valeurs n’a pas de lien avec le leadership transformationnel, mais que c’est le cas pour certaines valeurs au niveau personnel et organisationnel qui présentent effectivement un lien. Le deuxième article porte sur le potentiel rôle modérateur de la congruence des valeurs personne-organisation des subordonnés dans la relation entre le leadership transformationnel et les comportements d’habilitation. Les résultats montrent que la congruence des valeurs peut effectivement modérer cette relation, et que la forme de la modération peut dépendre de l’ancienneté des employés. Le troisième article traite du rôle modérateur de la présence de valeurs et de leur congruence au niveau de l’équipe dans la relation entre le leadership transformationnel et les comportements d’habilitation. Les résultats suggèrent que les valeurs et leur congruence dans les équipes peuvent modérer l’efficacité du leadership transformationnel en regard des comportements d’habilitation. De façon générale, la présence et la congruence de cinq valeurs, parmi les sept testées, semblent rehausser la relation entre le leadership transformationnel et les comportements d’habilitation. Ainsi, la présente thèse, en ajoutant des considérations quant aux questions qui avaient été soulevées par l’examen de la proposition théorique du rôle des valeurs et de leur congruence dans le leadership transformationnel, permet d’améliorer la compréhension de ce rôle. Spécifiquement, les résultats de cette thèse suggèrent que globalement, la congruence des valeurs peut être plus importante pour l’efficacité du leadership transformationnel lorsque les valeurs considérées sont plus importantes dans l’équipe de l’individu, et lorsque l’individu a peu d’ancienneté dans son organisation. De plus, en ce qui a trait aux leaders, il semble que la présence de valeurs de bien-être collectif et d’ouverture au changement ait un lien avec l’émission de comportements de leadership transformationnel. Une discussion traite de ces résultats et indique les limites de la thèse ainsi que des pistes de recherche future.

Shear Strength of Granular Materials, 1967

A theory was developed to allow the separate determination of the effects of the interparticle friction and interlocking of particles on the shearing resistance and deformational behavior of granular materials. The derived parameter, angle of solid friction, is independent of the type of shear test, stress history, porosity and the level of confining pressure, and depends solely upon the nature of the particle surface. The theory was tested against published data concerning the performance of plane strain, triaxial compression and extension tests on cohesionless soils. The theory also was applied to isotropically consolidated undrained triaxial tests on three crushed limestones prepared by the authors using vibratory compaction. The authors concluded that, (1) the theory allowed the determination of solid friction between particles which was found to depend solely on the nature of the particle surface, (2) the separation of frictional and volume change components of shear strength of granular materials qualitatively corroborated the postulated mechanism of deformation (sliding and rolling of groups of particles over other similar groups with resulting dilatancy of specimen), (3) the influence of void ratio, gradation confining pressure, stress history and type of shear test on shear strength is reflected in values of the omega parameter, and (4) calculation of the coefficient of solid friction allows the establishment of the lower limit of the shear strength of a granular material.

Les stratégies syndicales face aux restructurations d’entreprises : une étude comparative des contre-pouvoirs syndicaux dans le secteur des équipementiers automobiles en France et au Canada

Cette thèse tente de comprendre l’impact des restructurations des entreprises multinationales sur les stratégies syndicales. Les acteurs syndicaux locaux sont-ils déterminés par l’appartenance à des régimes nationaux et à des contingences organisationnelles ou peuvent-ils influencer des décisions objectives comme les restructurations ? Cette recherche s’insère dans une problématique large qui fait la jonction entre la mondialisation économique sur une base continentale, la réorganisation productive des entreprises multinationales et l’action syndicale. Au plan théorique, nous confrontons trois grandes approches analytiques, à savoir : le néo-institutionnalisme et les structures d’opportunités ; l’économie politique critique et la question du pouvoir syndical ; la géographie économique critique mettant de l’avant les contingences, l’encastrement et l’espace concurrentiel. Sur la base de ces trois familles, nous présentons un modèle d’analyse multidisciplinaire. Au plan méthodologique, cette thèse est structurée autour de quatre études de cas locales qui ont subi des menaces de restructurations. Cette collecte a été effectuée dans deux pays (la France et le Canada) et dans un secteur particulier (les équipementiers automobiles). Trois sources qualitatives forment le cœur empirique de cette thèse : des statistiques descriptives, des documents de sources secondaires et des entretiens semi-dirigés (44), principalement avec des acteurs syndicaux. L’analyse intra et inter régime national éclaire plusieurs aspects de la question des stratégies syndicales en contexte de restructurations. Les principales contributions de cette thèse touchent : 1. l’impact des facteurs relationnels et des ressources de pouvoir développées par les syndicats locaux sur les structures d’opportunités institutionnelles; 2. l’importance des aspects « cognitifs » et d’envisager le pouvoir de manière multi-niveaux; 3. l’importance de l’encastrement social et des dynamiques relationnelles entre syndicats et patronats; 4. l’influence de la concurrence internationale/nationale/régionale/locale dans le secteur des équipementiers automobiles; et 5. l’importance des arbitrages et des relations entre les acteurs de l’entreprise par rapport à la théorie de la contingence pour comprendre les marges structurelles des syndicats locaux. Notre recherche invite les acteurs sociaux à repenser leur action dans le cadre des restructurations. En particulier, les syndicats locaux se doivent d’explorer de nouveaux répertoires stratégiques pour répondre aux nombreux défis que posent le changement économique et les restructurations.

A representação social do papel de gestores em organizações não governamentais

The discussions concerning the absence of a management model appropriate to the peculiarities of third sector organizations have not been impeditive to their emphasized expansion in the last decades. In the attempt of understanding this phenomenon from the perspective of those who manage social organizations, this work based on the theory of social representations to understand the notion that organization managers of the third sector - based in Fortaleza CE - have of the part that they play and how this notion influences the direction of their activities. Social representations of managers of four different categories of non-governmental organizations have been investigated, each category composed of two unities. The categories researched were: social integration through art and education, prevention and treatment of alcohol and drug abuse, children s health assistance and community action. By using Doise s Societal Approach, the role of social managers translated in intraindividual, interindividual and situational processes of their actions, has been analysed within the social representations, focusing on beliefs, values, symbols and stories that give meaning to the existence of non-governmental organizations. Analysis and discussion of data displayed the existence of diversity in the understanding of managers within their practice, in other words, the management profile is also its own manager s. The branch where an organization acts is also preponderant in the shaping of a management style. It could be deduced, from to the organizations researched, that professional formation and the manager s social insertion mainly, are determinative factors in the outlining of a management model of its own. It was concluded that, due to heterogeneity of interests and action segments, there is no systematic process for social management among organizations. Management styles are supported by their director s own perception of achievement, who model organizations according to their contingencies

Climbing Up the Leaderboard: An Empirical Study of Applying Gamification Techniques to a Computer Programming Class

Conventional taught learning practices often experience difficulties in keeping students motivated and engaged. Video games, however, are very successful at sustaining high levels of motivation and engagement through a set of tasks for hours without apparent loss of focus. In addition, gamers solve complex problems within a gaming environment without feeling fatigue or frustration, as they would typically do with a comparable learning task. Based on this notion, the academic community is keen on exploring methods that can deliver deep learner engagement and has shown increased interest in adopting gamification – the integration of gaming elements, mechanics, and frameworks into non-game situations and scenarios – as a means to increase student engagement and improve information retention. Its effectiveness when applied to education has been debatable though, as attempts have generally been restricted to one-dimensional approaches such as transposing a trivial reward system onto existing teaching materials and/or assessments. Nevertheless, a gamified, multi-dimensional, problem-based learning approach can yield improved results even when applied to a very complex and traditionally dry task like the teaching of computer programming, as shown in this paper. The presented quasi-experimental study used a combination of instructor feedback, real time sequence of scored quizzes, and live coding to deliver a fully interactive learning experience. More specifically, the “Kahoot!” Classroom Response System (CRS), the classroom version of the TV game show “Who Wants To Be A Millionaire?”, and Codecademy’s interactive platform formed the basis for a learning model which was applied to an entry-level Python programming course. Students were thus allowed to experience multiple interlocking methods similar to those commonly found in a top quality game experience. To assess gamification’s impact on learning, empirical data from the gamified group were compared to those from a control group who was taught through a traditional learning approach, similar to the one which had been used during previous cohorts. Despite this being a relatively small-scale study, the results and findings for a number of key metrics, including attendance, downloading of course material, and final grades, were encouraging and proved that the gamified approach was motivating and enriching for both students and instructors.

Geografia da dominação: um estudo sobre a organização espacial da terra do sal (Macau-RN)

This work aims to understand the spatial organization in the Town of Macau, State of Rio Grande do Norte, Brazil. This approach focus on bringing back the history of the town, the main personages responsible for the construction of this place, denominated "social agents", as well as its social processes and the spatial forms derived from them. As the personages and their practices were identified, it was found out the existence of a driving force for structuring, interlocking, and maintaining the actions carried out by the social agents during the time. Such actions were materialized in the urban space: "the social segregation". The social segregation takes place as a specific geography of domination. The outcome of those owning the best areas" and ways of accessibility in the urban space, varies from the enrichment by property valorization, because of the concentration of public investments of infrastructure, to the comfort of easily reaching all the daily needs related to the displacements in the urban space. In the latter case, such facility has contributed to improve life quality. While one takes advantage of the location in the urban space, others are negatively affected by the same process. This research identified the salina worker as the weakest element of this social structure, occupying the urban periphery of the town of Macau. Such area is characterized by the lack of services and urban equipment in opposition to the center of the town, the locus of elite. This way, it is established the most known segregation pattern: center x periphery, in which the space acts as a mechanism of segregation

Ulisses e o feminino: eros e epos

Na Odisseia, as errâncias de um homem à procura de um destino e em luta sem tréguas pela sobrevivência, contra as contingências naturais da vida, constituem um dos motores da narrativa da viagem de regresso de Ulisses. No relato das suas aventuras aparecem um conjunto de estadias localizadas em sítios fantásticos e de encontros com figuras não humanas, geralmente representadas no feminino. Com base numa leitura dos célebres episódios eróticos de Circe, de Calipso e de Nausícaa, pretende-se neste artigo analisar como a díade epos-eros contribuiu para uma caracterização mais humanizada das experiências de vida de um herói astucioso e versátil, que foi capaz de resistir a todos os perigos e nunca se deixou iludir pelas tentações que punham em risco o seu nostos.

The Relation between Substance Use and Medication Adherence among HIV Positive Substance Users in Residential Treatment

Poor medication adherence is problematic among HIV positive, low-income African-American substance users. Substance use has been shown to be associated with poor medication adherence, though we do not know the mechanism that underlies this relationship. Lack of positive environmental rewards and the propensity to discount delayed rewards may be possible mechanisms to explain this relationship. Using baseline data from a randomized controlled trial, we examined the relationships between substance use and medication adherence, testing both environmental rewards and delay discounting as independent mediators. There was a main effect of substance use on adherence, such that high frequency of substance use predicted poor adherence. There was also a main effect of environmental rewards on adherence, such that a lack of environmental reinforcement predicted poor adherence. This study shed light on the processes that contribute to low adherence, namely substance use and lack of environmental contingencies, and suggests important targets for intervention.

O impacto das medidas da Troika no desempenho económico-financeiro das empresas portuguesas

Os efeitos despoletados com a crise financeira de 2008 marcaram uma mudança radical de pensamentos e políticas entre as várias economias mundiais. Esta crise ficou marcada pelo enorme esforço que as economias tiveram que suportar, obrigando todos mercados a moldarem-se em função das contingências implementadas. Após análise e leitura de diversa literatura é consensual a referência ao início da crise financeira nos Estados Unidos da América (EUA) com o chamado subprime, percebendo-se também que muito rapidamente atingiria a Europa e todo o mundo. Desta forma, a Europa e inevitavelmente Portugal, acabaria por ser atingido e sofrer diversas consequências resultantes desta crise financeira. Na verdade, fruto da enorme turbulência dos mercados mundiais e da globalização, Portugal (incapaz de por si só sair da crise em que se viu envolvido) vê-se na necessidade de recorrer a ajuda externa por parte da Troika. Neste sentido, a presente dissertação tem como objetivo relatar resumidamente o início da crise financeira mundial, analisando o impacto das políticas de combate à crise implementadas em Portugal, no desempenho económico-financeiro das empresas portuguesas. Este estudo recaiu sobre a análise e perceção de comportamento de alguns indicadores económico financeiros entre os anos de 2010 a 2014, período durante o qual a Troika esteve presente em Portugal, implementando uma serie de reformas e políticas de combate à crise. Assim, debruçamo-nos sobre quatro setores de atividade (Construção Civil, Restauração, Hotelaria e Indústria do Calçado), observando os dados financeiros extraídos da base de dados SABI (Sistema de análise de Balanços Ibéricos) sobre empresas inseridas nos respetivos setores de atividade. Com base nos resultados do estudo realizado podemos concluir que o desempenho dos indicadores económico financeiros foram mais penalizados nos setores da Construção Civil e da Hotelaria.
