The importance of physical tests in evaluating the level of some physical attributes of soccer players
No full textThe study that is in your hands aims to know the importance of physical tests in evaluating the level of some physical attributes of soccer players , and for that we followed the descriptive approach, where the sample of the study amounted to 16 coaches and we used to collect data the questionnaire whose results were analyzed by calculating k2 and percentages, The most important results of the study are that most of the trainers are aware of the importance of physical tests in evaluating some physical characteristics, so we find that they use them Before each stage of training, to know the current level of the player, and thus set the appropriate program. The study reported that the trainers perform physical tests after each stage of training to determine the extent of the development of the level of some qualities, and the results obtained from physical tests help determine the training program and it We recommend conducting periodic tests to measure the level of physical attributes of the players and providing physical tests and modern methods for coaches
Un champ associatif tunisien en quête de reconnaissance : entre légitimité historique et légitimité rationnelle
No full textEn peu de temps, les ONG ont réussi à s'imposer comme des interlocuteurs incontournables des États et des Organisations Internationales. De ce fait, elles sont de plus en plus interrogées sur leur efficacité et leur légitimité à agir. Elles s'efforcent désormais à justifier leur existence en démontrant leur utilité sociale. De quel(s) type(s) de légitimité(s) une OSC tunisienne peut-elle se prévaloir aujourd'hui dans un contexte de transition politique ? Est-ce seulement en avançant son passé qu'une organisation est aujourd'hui entendue, reconnue et considérée comme influente ? À travers une étude des modes de légitimations de deux associations tunisiennes, nous verrons comment les décisions et les évènements passés influent sur les décisions actuelles et futures d'une organisation. Par ailleurs, ce mémoire entend également démontrer l'influence des discours de légitimation sur la structure organisationnelle d'une association. Un peu moins de deux ans après l'immolation de Mohamed Bouazizi à Sidi Bouzid, la société civile tunisienne doit faire face à de nombreux défis d'ordres conjoncturels et structurels. Les associations tunisiennes se lancent désormais dans une difficile quête de reconnaissance sociale. Les organisations dites "traditionnelles", parmi lesquelles la Ligue Tunisienne de défense des Droits de l'Homme, ont résisté aux différentes politiques de déstabilisation du régime de Ben Ali. Leur notoriété découle aujourd'hui de cette légitimité historique. Or, l'ouverture du champ politique marque le début de la concurrence entre les associations. Dans ce contexte, la légitimité d'une organisation se fonde désormais sur des critères liés à la qualité, l'efficacité, la transparence, l'expertise ou encore le professionnalisme de celle-ci. La LTDH doit donc s'engager vers une réorganisation de son mode de fonctionnement sous peine d'être concurrencée par des associations plus jeunes, qui ne détiennent certes pas de légitimité historique, mais qui se montrent tout de même capables de répondre aux besoins de la société tunisienne. Fondé en mai 2011, le Forum Tunisien pour les Droits Économiques et Sociaux est décidé à prendre le relais d'une LTDH diminuée par une crise de légitimité. Responsable de l'organisation du FSM en mars 2013, elle a la possibilité d'accroître sa visibilité et de devenir ainsi un acteur incontournable sur la scène nationale. Ainsi, le contraste saisissant entre l'image d'association en déclin de la LTDH et l'essor impressionnant de cette jeune association qu'est le FTDES peut s'expliquer à travers une étude des processus de légitimation des deux organisations
The contribution of green plant parts to grain filling of durum wheat under water deficit
No full textThe grain developing and filling are considered as key step for durum wheat yield (Triticum turgidum), under water deficit. The present work aimed to evaluate the contribution of green organs to grain filling. Excision and shading the green organs were performed on five genotypes contrasted for their reaction for the water deficit. The experiment was conducted under three water treatments, 100%, 60% and 30% of field capacity. The contribution of current photosynthesis and reserves remobilization in the grain filling, were obtained by excision and shading of plant organs. The results showed that the contribution of each green organ to grain filling was dependent greatly on genotype and also the water supply. The photosynthetic activity of ear and reserves re-mobilization, contributed the largest rates in grain filling. This contribution, mainly the remobilization, increased more in most genotypes under the water deficit. The contribution rate of the current photosynthesis of the flag leaf and awns proved more effective in well-watered conditions. The reserves translocation resulting from the photosynthetic activity of the spike’s neck for grain filling were greatly dependent on the genotypes where it was higher in ACSAD1361 and Waha. However, it rose with increasing water deficit
