O trabalho coletivo do Departamento de Educação Física e a gestão da ecologia das aulas : a integração da agenda social dos alunos nas decisões de planeamento e ação dos professores

O estudo das condições que potenciam o ensino-aprendizagem em educação física precisa de considerar mais consistentemente e explicitamente as evidências do mesossistema estabelecido entre as ecologias do trabalho colaborativo do grupo disciplinar e as das suas aulas. Especificamente, incita-se à compreensão como a negociação integradora do sistema social dos alunos pode ser potenciada pelo grupo disciplinar. Para alcançar essa compreensão articularam-se os modelos das comunidades de aprendizagem profissional e da ecologia da aula, através da bioecologia do desenvolvimento humano. Conduziu-se um desenho de estudo de caso longitudinal integrado, triangulando métodos, fontes e dados de um grupo disciplinar de educação física com qualidade colaborativa. Simultaneamente, observaram-se duas ecologias de aulas de educação física, diferenciadas pelas disposições de negociação dos respetivos professores, detalhando paralelamente os perfis de agenda social dos alunos para essas ecologias. Os resultados permitem salientar a interação das propriedades Pessoa-Contexto-Processo-Tempo como condições mesossistémicas favorecedoras da integração do sistema social dos alunos, nomeadamente: as caraterísticas do grupo como comunidade de aprendizagem profissional focada na integração; a interação macrossistémica e a alternância intencional cíclica grupo-aula; e a articulação entre o desenvolvimento curricular colaborativo e a partilha e produção de conhecimento em espirais curriculares plurianuais e anuais. Estas condições refletiram-se nas ecologias das aulas como semelhanças tendencialmente integradoras do sistema social na instrução e na organização. Todavia, também emergiram particularidades em cada ecologia traduzidas numa congruência mais consistente entre os perfis de agenda social encontrados para o envolvimento integrador, por associação às diferenças de alinhamento instrucional na negociação pelos professores. Este estudo lança implicações para a investigação relacionadas com a verificação e aprofundamento das condições mesossistémicas identificadas. Paralelamente, a prática profissional de professores e de formadores de professores encontra implicações sobre a melhoria da qualidade colaborativa profissional para promover continuamente melhores experiências de ensino-aprendizagem da educação física nos microssistemas aqui analisados.

La négociation mixte : observation de la négociation d’une convention collective

Dans le domaine des relations industrielles, on a vu apparaître, ces dernières années, différents changements au niveau des relations du travail, notamment en matière de négociation collective. En effet, de nouvelles formes de négociation ont vu le jour en réponse aux changements qui se sont produits sur le marché du travail. De façon plus précise, les théoriciens se sont penchés, d’une part, sur des méthodes de négociation moins conflictuelles et les acteurs concernés par la négociation collective ont su les mettre en pratique, d’autre part. Cependant, bien que certains aient tenté de substituer ces méthodes plus coopératives à la négociation traditionnelle de façon intégrale, les théoriciens et praticiens se sont aperçus qu’il était plutôt difficile de les adopter à l’état pur et ce, de façon alternative à la négociation traditionnelle. Afin d’optimiser les gains mutuels lors de la négociation d’une entente, les négociateurs vont plutôt opter pour un usage combiné des méthodes plus traditionnelles et des nouvelles formes dites plus coopératives; on parle alors de négociation mixte. Toutefois, peu d’études portant sur la négociation mixte ont été conduites. Nous croyons néanmoins que cette forme de négociation est plus appropriée, notamment en raison de la nature des enjeux traités à l’occasion d’une négociation collective. S’insérant dans ce contexte, l’objet de notre recherche est donc l’étude, par l’entremise d’un cas particulier, de la négociation mixte. De façon plus précise, nous cherchons à évaluer la méthode de négociation adoptée lors de la négociation collective ayant eu lieu entre le Centre de la petite enfance Pomme Soleil (CPE) et le Syndicat des intervenantes en petite enfance de Montréal (SIPEM) – CSQ en 2005. Afin d’y parvenir, nous avons vérifié les propositions et hypothèses suivantes : (1) la nature du climat des négociations précédentes a une influence sur la méthode de négociation de type mixte adoptée par les parties au cours de la négociation de la convention collective, (2) la nature du climat des relations industrielles a une influence sur la méthode de négociation de type mixte adoptée par les parties au cours de la négociation de la convention collective, (3) le passage du temps a un effet de transition sur la méthode de négociation de type mixte qui manifeste une dominante intégrative dans les étapes initiales de la négociation et une dominante distributive dans les étapes finales, (4) les négociateurs ayant reçu une formation à la négociation basée sur la résolution de problèmes ou basée sur les intérêts adoptent une méthode de négociation de type mixte à dominante intégrative, (5) l’expérience des négociateurs patronal et syndical a une influence sur la méthode de négociation de type mixte adoptée par les parties au cours de la négociation de la convention collective, (6) la stratégie de négociation initiale adoptée par les parties a une influence sur la méthode de négociation de type mixte au cours de la négociation de la convention collective et (7) la négociation des clauses à incidence pécuniaire donne lieu à une méthode de négociation de type mixte à dominante distributive. Grâce aux résultats que nous avons recueillis par l’entremise de l’observation de la négociation collective entre le CPE Pomme Soleil et le SIPEM, mais principalement par le biais des entrevues, nous sommes en mesure d’affirmer que, conformément à notre question de recherche, la négociation fut mixte, à dominante intégrative. Cependant, la question salariale, bien qu’elle ne fut pas abordée à la table de négociation mais avec le gouvernement provincial, prit une tangente distributive. En ce sens, nous pouvons dire que la négociation fut mixte et ce, de façon séquentielle.

Diversity of free-living marine nematodes (Enoplida) from Baja California assessed by integrative taxonomy

We used morphological and molecular approaches to evaluate the diversity of free-living marine nematodes (order Enoplida) at four coastal sites in the Gulf of California and three on the Pacific coast of Baja California, Mexico. We identified 22 morphological species belonging to six families, of which Thoracostomopsidae and Oncholaimidae were the most diverse. The genus Mesacanthion (Thoracostomopsidae) was the most widespread and diverse. Five allopatric species, genetically and morphologically differentiated, were found in two localities in the Gulf of California (M. sp1 and M. sp2) and three in the Pacific coast (M. sp3, M. sp4 and M. sp5). Overall, we produced 19 and 20 sequences for the 18S and 28S genes, respectively. Neither gene displayed intraspecific polymorphisms, which allowed us to establish that some morphological variation was likely either ontogenetic or due to phenotypic plasticity. Although 18S and 28S phylogenies were topologically congruent (incongruence length difference test, P > 0.05), divergences between species were much higher in the 28S gene. Moreover, this gene possessed a stronger phylogenetic signal to resolve relationships involving Rhabdodemania and Bathylaimus. On the other hand, the close relationship of Pareurystomina (Enchilidiidae) with oncholaimids warrants further study. The 28S sequences (D2D3 domain) may be better suited for DNA barcoding of marine nematodes than those from the 18S rDNA, particularly for differentiating closely related or cryptic species. Finally, our results underline the relevance of adopting an integrative approach encompassing morphological and molecular analyses to improve the assessment of marine nematode diversity and advance their taxonomy.

Impact of Childhood Cancer on Parents` Relationships: An Integrative Review

Purpose: The diagnosis of cancer and the treatment decisions associated with it may cause uncertainty, stress, and anxiety among parents. Emotional tensions can affect parents` relationships during the trajectory of the child`s cancer illness. We conducted an integrative review to examine the evidence related to the effects of childhood cancer on parents` relationships. Methods: An integrative literature search of studies published between 1997 and 2009 was conducted in the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Psychology Information (PsycINFO), PubMed, Scopus, CUIDEN, and Latin American and Caribbean Health Science Literature (LILACS). The key words used were neoplasms, child, marriage, spouses, family relations, and nursing. Articles were reviewed if the (a) topic addressed parents` relationships during childhood cancer; (b) participants were mothers, fathers, or both; (c) design was either qualitative or quantitative; (d) language was English, Portuguese, or Spanish; (e) date of publication was between January 1997 and October 2009; and (f) abstract was available. Results: Fourteen articles met the search criteria and were reviewed using Cooper`s framework for integrative reviews. Four themes emerged: (a) changes in the parents` relationship during the trajectory of the child`s illness; (b) difficulty in communication between couples; (c) gender differences in parental stress and coping; and (d) role changes. Conclusions and Implications: Findings revealed positive and negative changes in parents` relationships, communication, stress, and roles. Nurses need to assess the impact of cancer diagnosis and treatments on parent relationships, offer support and encouragement, and allow expression of feelings. Future research is needed to develop and test interventions that increase parents` potentials and strengthen relationships during the challenging trajectory of their children`s cancer and treatment. Clinical Relevance: The multiple sources of stress and uncertainty associated with a child`s cancer diagnosis and treatment affect parents` relationships. Difficulties in communication appear frequently in parents` relationship. Our findings may guide healthcare professionals in identifying parents at risk for developing conflicts, communication problems, and lack of alignment between parents that could interfere with providing optimal care for their child with cancer. Healthcare professionals may promote dialogue and encourage parents to express their feelings, seek mutual support, and establish a partnership in dealing with the child`s illness.

DR-NEGOTIATE - A system for automated agent negotiation with defeasible logic-based strategies

This paper reports on a system for automated agent negotiation, based on a formal and executable approach to capture the behavior of parties involved in a negotiation. It uses the JADE agent framework, and its major distinctive feature is the use of declarative negotiation strategies. The negotiation strategies are expressed in a declarative rules language, defeasible logic, and are applied using the implemented system DR-DEVICE. The key ideas and the overall system architecture are described, and a particular negotiation case is presented in detail.

An integrative approach for studying the etiology of alcoholism and other addictions

Studies of alcoholism etiology often focus on genetic or psy-chosocial approaches, but not both. Greater understanding of the etiology of alcohol, tobacco and other addictions will come from integration of these research traditions. A research approach is outlined to test three models for the etiology of addictions — behavioral undercontrol, pharmacologic vulnerability, negative affect regulation — addressing key questions including (i) mediators of genetic effects, (ii) genotype-environment correlation effects, (iii) genotype x environment interaction effects, (iv) the developmental unfolding of genetic and environmental effects, (v) subtyping including identification of distinct trajectories of substance involvement, (vi) identification of individual genes that contribute to risk, and (vii) the consequences of excessive use. By using coordinated research designs, including prospective assessment of adolescent twins and their siblings and parents; of adult substance dependent and control twins and their MZ and DZ cotwins, the spouses of these pairs, and their adolescent offspring; and of regular families; by selecting for gene-mapping approaches sibships screened for extreme concordance or discordance on quantitative indices of substance use; and by using experimental (drug challenge) as well as survey approaches, a number of key questions concerning addiction etiology can be addressed. We discuss complementary strengths and weaknesses of different sampling strategies, as well as methods to implement such an integrated approach illustrated for the study of alcoholism etiology. A coordinated program of twin and family studies will allow a comprehensive dissection of the interplay of genetic and environmental risk-factors in the etiology of alcoholism and other addictions.

China's proposing behavior in Global Governance: the cases of the WTO Doha Round negotiation and G-20 process

This article examines China's proposals on the reform of global governance, and discusses the main features of China's proposing behavior in the cases of the WTO Doha Round negotiation and G-20 Process. The main findings are: (1) in the critical junctures of global governance reform, China engaged the reform of the global governance institutions proactively, and put forward a series of reform proposals; (2) in proposing behavior, China argued the global governance institutions should be properly adjusted without intention to change the basic principles, refrained from playing a leadership role while proposing jointly with other countries, and upheld the principled idea of pro-development.

A novel framework for modeling value for the customer, an essay on negotiation

This paper proposes a novel framework for modelling the Value for the Customer, the so-called the Conceptual Model for Decomposing Value for the Customer (CMDVC). This conceptual model is first validated through an exploratory case study where the authors validate both the proposed constructs of the model and their relations. In a second step the authors propose a mathematical formulation for the CMDVC as well as a computational method. This has enabled the final quantitative discussion of how the CMDVC can be applied and used in the enterprise environment, and the final validation by the people in the enterprise. Along this research, we were able to confirm that the results of this novel quantitative approach to model the Value for the Customer is consistent with the company's empirical experience. The paper further discusses the merits and limitations of this approach, proposing that the model is likely to bring value to support not only the contract preparation at an Ex-Ante Negotiation Phase, as demonstrated, but also along the actual negotiation process, as finally confirmed by an enterprise testimonial.
