Text in French / Member of the union of black workers in the port of Marseille, in France, and an eyewitness to the misery of black workers in the European environment, Sembène Ousmane, in 1956, wrote, using his personal experiences, his first book entitled The Black Docker. In this novel, he describes the sufferings of the working class, the struggle between colonisers and colonised. In 1960, he uses as a pretext the strike of the Senegalese railway workers in 1937 to write a book entitled God's Bits of Wood. In this story where two forces clashed, on one hand, the colonised struggling against the colonial system and want, at all costs, to improve their living conditions, and on the other hand, the colonisers that are in support of their colonialist ideals and refuse the changes, the author tells the epic story of strikers in Senegal and their relentless struggles against the colonisers to change their living conditions for better. In 1973, an eyewitness of the daily realities of his native country, Senegal, after gaining national sovereignty, Sembène Ousmane wrote and published a book entitled Xala. In this book, he describes the evils of neo-colonialism and criticises the new African middle class, born after independence. After reading these novels, one notes that Sembène Ousmane, a defender of freedom, denounces the injustices done to the blacks, both in the colonial era as well as in the post colonial period. This is why from a book to another, he continues tirelessly his struggle against colonialism and neo-colonialism, evoking the sufferings and tragedies endured by the Africans. It occurs constantly in his imaginary creations, a theme, or better still a dialectical; commitment and militancy. What does he mean by « commitment » and « militancy » ? How do these two concepts manifest themselves in the works of the Senegalese writer? What strategy does he propose to the oppressed in the struggle against the oppressors? What means has he put at the disposal of the disinherited struggling to break the yoke of oppression and exploitation in order to achieve freedom and equality? / Membre du syndicat des travailleurs noirs, au port de Marseille, en France, et témoin oculaire de la misère vécue par les ouvriers noirs dans ce milieu européen, Sembène Ousmane, en 1956, écrit, en se servant de ses expériences personnelles, son premier ouvrage intitulé Le Docker noir. Dans ce roman, il décrit la souffrance de la classe ouvrière, la lutte entre colonisateurs et colonisés. En 1960, il se sert d’un prétexte, la grève des ouvriers sénégalais en 1937, pour écrire un ouvrage intitulé Les Bouts de bois de Dieu. Dans ce récit, où s’affrontent deux forces, d’une part les colonisés qui luttent contre le système colonial et veulent, à tout prix, l’amélioration de leurs conditions de vie, et d’autre part, les colonisateurs qui soutiennent les idéaux colonialistes et refusent le changement, l’auteur relate l’histoire épique des grévistes au Sénégal, et la lutte implacable qu’ils mènent contre les colonisateurs pour le changement de leurs conditions de vie. En 1973, témoin oculaire des réalités quotidiennes de son pays natal, le Sénégal, après son accession à la souveraineté nationale, Sembène Ousmane écrit et publie, un ouvrage intitulé Xala. Dans ce livre, il décrit les méfaits du néocolonialisme et critique la nouvelle classe bourgeoise africaine, née après l’indépendance. Après lecture des trois romans, on constate que Sembène Ousmane, défenseur de la liberté, dénonce les injustices faites aux Noirs, aussi bien à l’époque coloniale qu’à la période postcoloniale. C’est pourquoi, d’un ouvrage à l’autre, il continue, inlassablement, sa lutte contre le colonialisme et le néocolonialisme, en évoquant les souffrances et les drames endurés par les Africains. Il revient, constamment, dans ses créations imaginaires, à une thématique, ou mieux une dialectique, l’engagement et le militantisme. Qu’entend-il par « engagement » et « militantisme »? Comment ces deux lexèmes se manifestent-ils dans les écrits de cet écrivain sénégalais? Quelles stratégies propose-t-il aux opprimés dans la lutte qui les oppose aux oppresseurs? Quels moyens met-il a la disposition des déshérités en lutte pour briser le joug de l’oppression et celui de l’exploitation afin d’obtenir la liberté et l’égalité? / Linguistics and Modern Languages / D.

It also aims to probe the existence of a modulating effect between this relationship and the respective team' s pressure perception. One of the challenges that managers face is how to keep a team motivated and mobilized in an increasing pressure environrnent. In the first and second chapter we introduce the theme and define the Problem to be studied. In the third chapter, we walked through labor, organization and human history willing to ground in a timeline the joumey in the search ofbalance laborlaborer, the mankind's place in shaping this history and some important thinkers of people management. This chapter is a door opener for the next one where we study stress, particularly, occupational stress. In this fourth chapter we point the difference between pressure - present in the environrnent - and stress, derived from the individual interpretation. Our interest in this subject comes from the observation that pressure arises when the market suffers a retraction but also arises when it is heated, so, it increases every time. So, if there is a correlation between how teams or a person 'perceives' his leader and the 'pressure around', this information could be useful for people management, particularly addressing occupational stress. We deepen the concept of Social Support, the net that protects the employee in high-pressure contexts with an emphasis on the leader's role as the main source ofthis support. In chapter 5 we deepen in conjlict due to its' impact on occupational stress leveIs. The workplace relationship is, by its nature, a long term relationship and that makes conflict management a relevant issue on manager's agenda. However, the appropriate conflict management depends on the diagnosis (technical approach) and the confidence leveI build in the relationship (relationallevel). Although we are aware that significant part of the conflicts are related to the corporate structure and strategy, we purposely drove our attention to managers and middle leaders that are part of more representative part of the company' s leadership group aiming to provoke ideas that could contribute to the relationships and results improvement. In chapter six we present the Methodology used and in the seventh chapter we discuss the field research results carried with big companies' Human Resource managers. In this chapter we seek, through HR's sight, a perception over the impact of the leadership comparing them using a subjective perception of higher or lower negotiation capabilities with their teams. The research used a flexible grid supported by a semi-structured questionnaire. Data were decoded by Content Analysis method. Due to the sample size, a statistic treatment was not necessary. The evaluation allow infer that there is a straight relationship between a leader behavior over his team stress perception at the workplace. The study pointed the need for a deeper analysis of the issue considering that the literature and the initial results show an important role of immediate report over the team stress leveI perception. Concluding this study, the research offers questions regarding the company and the leader role on dealing with teams under constant pressure. / Este estudo tem por finalidade identificar perspectiva dos profissionais de Recursos Humanos a correlação entre as competências gerenciais e a relação construída entre líderes de diferentes níveis hierárquicos e suas equipes diretas, bem como o impacto na percepção da pressão e do estresse pelas suas respectivas equipes. Um dos desafios que gerentes e outros líderes encontram é como manter um time motivado e mobilizado em um ambiente de pressão crescente, seja decorrente de uma expansão ou uma retração do seu mercado. No primeiro capítulo e no segundo capítulos fazemos a introdução e a definição do Problema, os objetivos e delimitações do estudo. No terceiro capítulo caminhamos pela história do trabalho, da organização e do homem, buscando fundamentar no tempo a jornada em busca do equilíbrio trabalho e trabalhador, o lugar do homem na construção desta história e alguns importantes pensadores da gestão de pessoas. Este capítulo abre portas para entendermos o capítulo seguinte, no qual estudamos o estresse e, em particular, o estresse ocupacional. Mostramos, ainda, a diferença entre pressão – que está no ambiente externo- e estresse, que deriva da percepção do indivíduo. O interesse neste tema é decorrente da constatação prática de que a pressão aumenta em tempos de retração do mercado, mas também aumenta em períodos em o mercado está aquecido. Logo, se houver uma correlação entre como uma equipe ou um liderado ‘percebe’ o seu líder, essa informação poderá ser útil para a Gestão de Pessoas. Aprofundamos o conceito de Suporte Social, a rede que protege o colaborador nem contextos de alta pressão e demos maior ênfase ao papel do líder como importante fonte deste suporte. No quinto capítulo analisamos o tema conflito por ser um dos temas que mais impactam o estresse ocupacional. As relações de trabalho são, por sua natureza, relações de longo prazo, o que faz do manejo adequado do conflito no ambiente de trabalho um assunto relevante na agenda do gerente. Entretanto, seu manejo adequado depende tanto do diagnóstico correto, bem como da relação de confiança construída pelo líder. Embora cientes de que parte significativa dos conflitos está relacionada às estruturas e estratégias corporativas, propositalmente dirigimos nossa atenção aos gerentes e líderes que compõem a massa de liderança dessas organizações visando provocar idéias que possam contribuir para a melhoria das relações e dos resultados. No sexto capitulo apresentamos a Metodologia e no último capítulo apresentamos e discutimos o resultado da pesquisa realizada com profissionais de Recursos Humanos de grandes empresas, buscando, através do olhar do RH, uma percepção sobre as lideranças de cada empresa e a comparação entre líderes com maior ou menor capacidade de negociação junto à sua equipe. O estudo usou uma grade flexível suportada por um questionário semi-estruturado e os dados foram tratados usando a metodologia da Análise de Conteúdo sem que fosse necessário um tratamento estatístico devido ao tamanho da amostra. O estudo apontou para a necessidade de uma exploração mais profunda do tema uma vez que a literatura e os resultados iniciais demonstraram um importante papel da chefia direta na percepção grupal do estresse e no clima organizacional. Ao concluir o trabalho a pesquisa oferece algumas ponderações sobre o papel das lideranças e o papel das corporações na equalização de equipes que vivem sob pressão constante.

Les nématodes à galles demeurent l'un des problèmes les plus graves des ‎agriculteurs de serres du Liban et du Moyen-Orient. Dans le passé, la fumigation du sol au ‎bromure de méthyle a été considérée comme la meilleure mesure de contrôle contre ces ‎nématodes. Toutefois, à la lumière de l'élimination globale du bromure de méthyle, l'accès ‎aux alternatives efficaces et durables est devenu une nécessité essentielle.‎L'objectif de cette étude est d'évaluer l'efficacité des deux engrais verts, le radis ‎huileux (Raphanus sativus oleifera) et à la roquette (Eruca vesicaria sativa) appliquées ‎avec ou sans bâche en plastique, séparément et en combinaison avec Oxamyl, dans la ‎gestion des nématodes à galles en cultures de concombres de serre. En outre, cette étude ‎vise à évaluer la faisabilité financière de la technique de biofumigation avec les deux ‎cultures utilisées et de la rentabilité finale de ces engrais verts en termes de taux coût-profit ‎par rapport au bromure de méthyle.‎A cette fin, trois expériences sur le terrain ont été menées dans des serres ‎commerciales, situées sur la zone côtière du Liban.‎Dans les deux expériences A et B, des résultats cohérents ont été enregistrés en ‎termes de production de rendements significativement plus élevés et de la réduction des ‎populations de nématodes avec les engrais verts‎ utilisés avec ou sans bâche en plastique, ‎par rapport au témoin non traité.‎Quant aux résultats obtenus par les engrais verts‎ par rapport ‎ au bromure de ‎méthyle, dans l'expérience A, le rendement produit par le bromure de méthyle était ‎significativement plus élevé que celui du radis huileux avec bâche en plastique. ‎Cependant, la différence n'était pas significative entre la réduction de la population de ‎nématodes résultant du bromure de méthyle et celle du radis huileux avec bâche en ‎plastique. Les différences du rendement ainsi que la réduction des nématodes étaient ‎significatives entre le bromure de méthyle et le radis huileux sans bâche en plastique.‎Dans l'expérience B, aucune différence significative n'a été observée dans le ‎rendement ni la réduction de la population de nématodes entre aucun des deux engrais ‎verts‎ utilisés avec bâche en plastique et le bromure de méthyle. Ces différences étaient ‎significativement en faveur du bromure de méthyle uniquement lorsque le radis huileux a ‎été utilisé sans bâche en plastique.‎Dans l'expérience C, où Vydate (Oxamyl) a été appliqué à la dose de 1 litre par 1,000 ‎m2 à tous les traitements, il n'y avait pas de différence significative dans le rendement ni la ‎réduction de la population de nématodes entre chacun des deux engrais verts utilisés avec ‎ou sans bâche en plastique et le bromure de méthyle.‎L'analyse coût-profit menée sur tous les traitements appliqués dans les 3 ‎expériences a montré que dans tous les cas, tous les traitements appliqués, qu'ils soient ‎chimiques, non-chimique (avec ou sans bâche en plastique) ou en association ont produit ‎des bénéfices nets supérieurs au bromure de méthyle, même lorsque le rendement produit ‎par le bromure de méthyle était significativement plus élevée.‎L'utilisation du plastique pour couvrir les radis huileux a généralement produit de ‎meilleurs résultats en termes de production de rendements plus élevés, une meilleure ‎réduction des populations de nématodes à galles dans le sol, ainsi conduisant à des ‎augmentations raisonnables des profits nets.‎A la base de ces résultats et à la lumière de l'élimination globale du bromure de ‎méthyle, on peut conclure que l'utilisation du radis huileux et la roquette comme engrais ‎verts avec bâche en plastique peut être considéré comme un outil alternatif pour la gestion ‎des nématodes à galles dans la production de concombres de serre dans les conditions ‎libanaises.‎ / Root-knot nematodes remain one of the most serious problems faced ‎by ‎greenhouse farmers of Lebanon and the Middle East region. In the past, soil fumigation ‎with methyl bromide has been considered as ‎the best control measure against root-knot ‎nematodes. However, in the light of the global phase out of methyl bromide, finding ‎efficient and viable alternatives is an essential necessity.‎The objective of this study is to evaluate the efficacy of the two biofumigation ‎crops ‎Oil Radish (Raphanus sativus oleifera) and Arugula (Eruca vesicaria sativa) applied ‎with ‎and without plastic tarp, separately and in combination with Oxamyl in the ‎management of ‎the root-knot nematodes in greenhouse cucumber crops. Additionally, this ‎study aimed at ‎assessing the financial feasibility of the biofumigation technique with the ‎two cops used ‎and the final profitability of these green manure crops in terms of cost to ‎benefit ratio as ‎compared to methyl bromide.‎For this purpose, three field experiments were carried out in ‎commercial ‎greenhouses situated on the coastal zone of Lebanon.‎In both experiments A & B consistent results were recorded in terms of production ‎of ‎significantly higher yields and reduction of nematode population with the ‎biofumigation ‎crops used whether with or without plastic cover, as compared to untreated ‎fallow.‎As to the results achieved by the biofumigation crops with respect to methyl ‎bromide, ‎in experiment A yield produced by methyl bromide was significantly higher than ‎oil radish ‎with plastic cover. However, no significant difference was found between ‎reduction of ‎nematode population resulting from methyl bromide and oil radish with plastic ‎cover. ‎Difference was significant between methyl bromide and oil radish without plastic ‎cover in ‎both yield and reduction of nematodes.‎In experiment B no significant difference was observed in neither yield nor ‎reduction ‎of nematode population between any of the two biofumigation crops used with ‎plastic ‎cover and methyl bromide. These differences were significantly in favor of methyl ‎bromide ‎only when oil radish was used without plastic cover.‎In experiment C where Vydate (Oxamyl) was incorporated at the rate of 1 liter ‎per ‎‎1,000 m2 to all treatments, there was no significant difference in neither yield nor ‎reduction ‎of nematode population between any of the two biofumigation crops used with or ‎without ‎plastic cover.‎Cost-benefit analysis made on all treatments applied in the 3 experiments ‎showed ‎that in all cases, all treatments applied, whether chemical, non-chemical (with or ‎without ‎plastic cover) or in combination have produced higher net profits than methyl ‎bromide, ‎even when yield produced by methyl bromide was significantly higher.‎Use of plastic for covering oil radish has generally produced ‎better results in terms ‎of ‎production of higher yields, better reduction of soil ‎populations of root-knot nematodes‏‎ ‎and ‎‏leading to ‎‏reasonable increases of net profits.‎Based on these findings and in the light of global phase out of methyl bromide, ‎it ‎can be concluded that the use of oil radish and arugula as biofumigation crops with ‎plastic ‎cover can be considered as ‎an alternative management tool for the root-knot ‎nematode in ‎greenhouse cucumber ‎production under Lebanese conditions.‎

The primary purpose of this study is to identify those people at most risk of being bullied at work. While much research is being conducted on school bullying, little has been conducted on workplace bullying. Using data gathered from a 2004 study conducted by the National Opinion Research Center for the General Social Survey, which included a Quality of Work Life (QWL) module for the National Institute for Occupational Safety and Health (NIOSH), linear regressions indicated significant findings. As predicted, workers in lower level occupations, as ranked by prestige scoring developed at National Opinion Research, are more likely to be victimized. Data also suggest that being young, Black, and relatively uneducated may contribute to being bullied in certain situations. Future research is needed to examine influences of socio-economic, legal, and other demographic factors that may predict the chance of being bullied.
