Optimització i aprofitament del temps de pràctica motriu en les classes deducació física d'un grup de 4t ESO

Amb aquest treball d‟investigació es pretén fer veure al docent la importància d‟una adequada gestió del temps de classe d‟Educació Física (E.F.), concretament, abans, durant i al final de la sessió, amb l‟objectiu d‟augmentar el temps de compromís motor dels alumnes. Tanmateix citaré autors i esmentaré estudis que demostren que un increment en el temps de compromís motor per part de l‟alumne, augmenta la probabilitat de que s‟assoleixin els objectius proposats i, per tant, el procés d‟ensenyament – aprenentatge serà més eficaç. En conseqüència, s‟analitzen les categories i variables temporals (temps d‟informació del professor, temps d‟organització dels alumnes i del material i temps d‟imprevistos) que poden restar minuts al temps de pràctica motriu i, a la vegada, es presenten una sèrie de recursos i estratègies que ajuden al professor d‟E.F a reduir les accions i variables temporals que incideixen negativament a fi i efecte d‟augmentar el temps de pràctica motriu.

Raison et déraison de la loyauté familiale: un cas clinique

Le concept de loyauté appliquée à l'univers de la thérapie familiale est énormément tributaire de la pensée de Boszormenyi-Nagy. Il semble le placer dans un registre humaniste mais immanent. Si on se réfère à son origine étymologique, la loyauté implique l'obligation légale de tenir la parole donnée. Les enfants apprennent tôt à être loyaux. Leurs comportements réparateurs à l'égard des parents, même négligents ou violents, sont considérés comme l'expression d'une loyauté transmise. L'auteur s'interroge sur l'articulation entre une loyauté comme qualité morale du sujet qui choisit de se soumettre à la loi, à la parole donnée et un conditionnement obligé qui contraint le sujet à assumer des comportements « déraisonnables ». Les avancées de la neurobiologie permettent de répondre, tout au moins en partie, à une telle question. The concept of loyalty in the field of the family therapy is in debt to Boszormenyi-Nagy's work. According to his thought, loyalty commitment is the result of a humanistic but immanent believe. Etymologically, loyalty implies legal commitment to fulfill the promise. Children learn in their early years to be loyal. Reparations towards their parents, even if neglecting or violent, are considered the expression of a transmitted loyalty. The author questions the articulation between loyalty as a moral quality of the subject who chooses to accept the law and the given word, and a forced conditioning which brings the subject to adopt "un-reasonable" behaviors. Recent advances in neuroscience enable us to answer this question, at to some extent.

CD8+ T cell development: CD4 to the rescue.

How immature CD4+CD8+ thymocytes become committed to either the CD4 (helper) or CD8 (cytotoxic) lineage is controversial. Genetic ablation of a silencer element in the gene encoding CD4 provides new evidence that CD8 lineage commitment occurs via a stochastic, rather than instructive, mechanism.

THE USEFUL SIDE OF AMBIVALENCE: Ambivalent attitudes can be adaptive and socially valued

En s'inspirant de la littérature récente qui a dépeint l'ambivalence comme étant adaptative et en lien avec des comportements stratégiques, cette thèse examine le versant utile des attitudes ambivalentes. Elle met tout d'abord en évidence que son expression peut-être sciemment contrôlée et mise en avant pour des raisons d'auto-présentation. De plus, elle démontre que les individus peuvent présenter une attitude ambivalente afin de gagner l'approbation sociale sur un objet d'attitude controversé alors que l'inverse a été observé sur des objets consensuels (Première ligne de recherche). Cette thèse a également révélé que l'expression d'attitudes ambivalentes pouvait amener à être valorisé socialement. En effet, contrairement à des attitudes plus tranchées (pro-normatives ou contre-normatives), les attitudes ambivalentes ont été évaluées de façon plus importante sur la dimension de l'utilité sociale (une dimension qui indique la compétence d'autrui ou encore la propension à évoluer dans la hiérarchie sociale). La valorisation de l'ambivalence n'est apparue que sur la dimension de l'utilité sociale et non sur la dimension de la désirabilité sociale (une dimension qui indique la sympathie d'autrui ainsi que la propension à être apprécié socialement). De plus, ce résultat a été observé sur des thèmes controversés et non sur des thèmes consensuels (Seconde ligne de recherche). Dans l'ensemble cette thèse soutient une approche de l'ambivalence comme donnant lieu à des bénéfices. Elle peut également ouvrir la voie à l'étude de l'ambivalence en lien avec la pensée critique. - Drawing on the recent literature that portrayed ambivalence as being adaptive and linked with strategic behaviors, this thesis examines the useful side of ambivalent attitudes. It first revealed that the expression of ambivalent attitudes could be controlled and purposely displayed for self-presentational concerns. Furthermore, it demonstrated that people could put ambivalence forward to gain social approval when expressing it on controversial social issues, whereas the opposite was true on consensual social issues (First line of research). The thesis also revealed that the expression of ambivalent attitudes could lead to be socially valued. Indeed, contrary to clear-cut attitudes (either pro-normative or counter-normative attitudes), ambivalent attitudes have been evaluated the highest on the social utility dimension (a dimension indicating people's competence as well as the extent to which they are likely to climb in social hierarchy). The valorization of ambivalent attitudes only appeared on social utility and not on social desirability (a dimension indicating people's niceness as well as the extent to which they are likely to be socially appreciated). This effect was true on controversial social issues but not on consensual ones (Second line of research). Overall, this thesis provides support for an approach that conceives attitudinal ambivalence as leading to benefits. It also may open avenues for the study of ambivalence in relation with critical thinking.

Improving Traffic Safety Culture in Iowa, 2011

Vehicle crashes rank among the leading causes of death in the United States. In 2006, the AAA Foundation for Traffic Safety “made a long- term commitment to address the safety culture of the United States, as it relates to traffic safety, by launching a sustained research and educational outreach initiative.” An initiative to produce a culture of safety in Iowa includes the Iowa Comprehensive Highway Safety Plan (CHSP). The Iowa CHSP “engages diverse safety stakeholders and charts the course for the state, bringing to bear sound science and the power of shared community values to change the culture and achieve a standard of safer travel for our citizens.” Despite the state’s ongoing efforts toward highway safety, an average of 445 deaths and thousands of injuries occur on Iowa’s public roads each year. As such, a need exists to revisit the concept of safety culture from a diverse, multi-disciplinary perspective in an effort to improve traffic safety. This study summarizes the best practices and effective laws in improving safety culture in the United States and abroad. Additionally, this study solicited the opinions of experts in public health, education, law enforcement, public policy, social psychology, safety advocacy, and traffic safety engineering in a bid to assess the traffic safety culture initiatives in Iowa. Recommendations for improving traffic safety culture are offered in line with the top five Iowa CHSP safety policy strategies, which are young drivers, occupant protection, motorcycle safety, traffic safety enforcement and traffic safety improvement program, as well as the eight safety program strategies outlined in the CHSP. As a result of this study, eleven high-level goals were developed, each with specific actions to support its success. The goals are: improve emergency medical services response, toughen law enforcement and prosecution, increase safety belt use, reduce speeding-related crashes, reduce alcohol-related crashes, improve commercial vehicle safety, improve motorcycle safety, improve young driver education, improve older driver safety, strengthen teenage licensing process, and reduce distracted driving.

Constitution, Diversification and Normalisation of a Health Problem: Organising the Fight against AIDS in Switzerland (1984-2005)

The article traces the formation, diversification and normalization of the AIDS cause in Switzerland. Particular emphasis is placed on interactions between the medical field, public authorities and associative space, the latter being understood as the place where individual and collective actors compete to define the cause. The authors argue that the major phases in the structuring of the struggle, the pace of state intervention and the creation of a multi-organizational field, can only be understood if one adopts a 'configurational perspective' attentive to the manner in which, in a given context and under the effect of particular constraints, key actors strategically interact and contribute to transforming their environment and their chances of reaching their goals. This approach takes into account the changing socio-biological characteristics of those who have committed themselves to the cause. In turn, internal movement divisions about how to respond to the epidemic as well as the changing perceptions of the disease have modified the opportunities for commitment, encouraging certain individual kinds of people and excluding others.

Less is more ? The Commission proposal on access to EU documents and the proper limits of transparency

Transparency is now seen as a key tool of democratic governance. The European Union's commitment to transparency is now at the centre of a crucial debate between the Commission and the Parliament on the future of citizen's right of access to information. This article presents the main characteristics of the current regime and questions the pertinence of the proposed changes in light of the international drive at modernising access to information laws and the attempt at identifying the ̳proper limits of transparency'. The questions raised range from the identification of what can be accessed to the definition of exemption and the protection of competing interests.

Travail militant, action collective et rapports de genre

In that paper we propose a gendered approach to social movements and political activism, based on a critical review of the litterature in French and English. In social movements and militantism studies, gender lines of division are most of the time ignored. Social movements are perceived as being « gender neutral ». However, that dimension is a determinant factor of collective action at the macro level of political opportunities and contexts, at the meso level of organisations and their modes of functionning, at the micro level of the logics of individual commitment and the division of militant labor.

09008-005 Hewitt Creek Final Report

The primary goal of the Hewitt Creek watershed council is to have Hewitt-Hickory Creek removed from the Iowa impaired waters (303d) list. Hewitt Creek watershed, a livestock dense 23,005 acre sub-watershed of the Maquoketa River Basin, is 91.2% agricultural and 7.5% woodland. Since 2005, sixty-seven percent of 84 watershed farm operations participated in an organized watershed improvement effort using a performance­ based watershed management approach, reducing annual sediment delivery to the stream by 4,000 tons. Watershed residents realize that water quality improvement efforts require a long-term commitment in order to meet their watershed improvement goals and seek funding for an additional five years to continue their successful watershed improvement project. Cooperators will be provided incentives for improved environmental performance, along with incentives and technical support to address feedlot runoff issues and sub-surface nitrate-nitrogen loss. The Phosphorus Index, Soil Conditioning Index and cornstalk nitrate test will be used by producers as measures of performance to refine nutrient and soil loss management and to determine effective alternatives to reduce nutrient and sediment delivery. Twenty-five livestock operations will improve feedlot runoff control systems and five sub-surface bioreactors will be installed to reduce nitrate delivery from priority tile-drained fields. The Hewitt Creek council will seek additional cost-share funding for high-cost feedlot runoff control structures, sediment control basins and stream bank stabilization projects.

Water Rights and Allocation, January 2010

Iowa Department of Natural Resources commitment to improving the management of both the quantity and quality of water resources, a committee was formed to assess the current policies and practices regarding water rights and allocation, and to make recommendations that would assist the state in moving toward a sustainable future. Water allocation concerns have been raised again in the past few years as increases in the demand for water are projected due to ethanol production, geothermal heating-cooling, and potential irrigation expansion.

Callings in career: A typological approach to essential and optional components

A sense of calling in career is supposed to have positive implications for individuals and organizations but current theoretical development is plagued with incongruent conceptualizations of what does or does not constitute a calling. The present study used cluster analysis to identify essential and optional components of a presence of calling among 407 German undergraduate students from different majors. Three types of calling merged: "negative career self-centered", "pro-social religious", and "positive varied work orientation". All types could be described as vocational identity achieved (high commitment/high self-exploration), high in career confidence and career engagement. Not defining characteristics were centrality of work or religion, endorsement of specific work values, or positivity of core self-evaluations. The results suggest that callings entail intense self-exploration and might be beneficial because they correspond with identity achievement and promote career confidence and engagement while not necessarily having pro-social orientations. Suggestions for future research, theory and practice are suggested.

06033-015 Fox River Watershed Final Report

With WIRB funding the Fox River Ecosystem Development board will install prioritized practices identified by assessments within the impaired segment of Fox River that currently will not be funded by Iowa Section 319 or Watershed Protection Funds. The FRED board is also asking for funding for a three year position for continuing assessment, planning, and technical assistance. Through various funding sources local work groups have been able to address some of the critical and high priority areas. But, as further assessments are made, commitment, and need expressed from landowners grow, the FRED board and SWCD districts in both Iowa and Missouri are committed not only to seek funding to continue water quality efforts for more practices but also enhance and protect existing practices and investments that protect our water quality and economic viability in both states.

08025-015 Remsen Source Water Protection Final Report

The City of Remsen is proactively addressing an increase of nitrates in their public water supply before it becomes a financial catastrophe for them. An intensive assessment was conducted by the Iowa DNR Source Water Protection program as one of four pilot projects in the state. This assessment far surpassed standard desktop assessments and gathered monitoring information in-the-field led by a local watershed group. This was incorporated into a computer modeling program to help the local watershed group discuss alternatives. This comprehensive approach clearly identified the source of nitrate infiltration as a cropland area adjacent to the City well field. Many options were evaluated but only one option provided an economical, viable and secure answer to the water supply needs of Remsen for generations to come. The watershed planning group chose to seek the purchase of this critical area of cropland and convert it to a deep rooted mixture of native grasses. This WIRB funding is intended to be used to acquire a small area totaling 21.1 acres. It represents about 22% of the total local project effort. This will be added to the existing City well field of 40.2 acres and another piece of adjacent property, 35.34 acres, that the City recently acquired as part of an overall aggressive program to protect the community water supply. The City has a signed purchase agreement for 14.4 acres of the 21.1 and a strong verbal commitment to obtain the remaining 5.7 acres. This project has been very active for almost 2 years and is ready to implement immediately upon funding notification. The establishment of native grasses, funded by the local chapter of Pheasants Forever, will take approximately the next three years of operation & maintenance.

06012-006 Lime Creek NPS Project Final Report

Lime Creek is a sub-watershed of the Cedar River above; approximately 25 miles from Cedar Rapids. The lower half of the stream is on the Iowa 2004 Section 303(d) impaired waters list. Monitoring by the Cedar River Watershed Monitoring Coalition documents that Lime Creek delivers above average amounts of nitrate+ nitrite-N, ammonia-Nand total phosphorus (above the 901 percentile) compared to other Cedar River sub-watersheds. The Cedar Rapids water utility is concerned about increasing delivery of nitrate+nitrate to the Cedar River, which provides drinking water for about 125,000 people in the area. A group of local citizens has formed the Lime Creek watershed council with the goal of reducing pollutant delivery to the creek and promoting sustainable, watershed-wide action by producers, urban and rural residents for improved environmental management. The council has established a performance-based program that rewards cooperators for improvement in research-based test and index scores which directly measure environmental impact of BMPs. The Iowa Com Growers Association is funding the performance rewards. The Watershed Coalition is contributing in-kind monitoring. Council and performance cooperators participate primarily with commitment of their own resources. WIRB funds will be used to increase program cooperators and for staff support. In addition to improvement of water quality in Lime Creek, the project will establish baseline values for arket-based a pro ch to valuing pollutant reduction by intensive livestock operations in eastern Iowa.
