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.

Clinical practice guideline on diagnosis and treatment of hyponatraemia

Hyponatraemia, defined as a serum sodium concentration <135 mmol/l, is the most common disorder of body fuid and electrolyte balance encountered in clinical practice. It can lead to a wide spectrum of clinical symptoms, from subtle to severe or even life threatening, and is associated with increased mortality, morbidity and length of hospital stay in patients presenting with a range of conditions. Despite this, the management of patients remains problematic. The prevalence of hyponatraemia in widely different conditions and the fact that hyponatraemia is managed by clinicians with a broad variety of backgrounds have fostered diverse institution-and speciality-based approaches to diagnosis and treatment. To obtain a common and holistic view, the European Society of Intensive Care Medicine (ESICM), the European Society of Endocrinology (ESE) and the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA), represented by European Renal Best Practice (ERBP), have developed the Clinical Practice Guideline on the diagnostic approach and treatment of hyponatraemia as a joint venture of three societies representing specialists with a natural interest in hyponatraemia. In addition to a rigorous approach to methodology and evaluation, we were keen to ensure that the document focused on patient-important outcomes and included utility for clinicians involved in everyday practice.

Spiritual Violence: Queer People and the Sacrament of Communion

This thesis addresses spiritual violence done to queer people in the sacrament of Communion, or Eucharist, in both Protestant and Roman Catholic churches in the U.S. Rooted in the sexual dimorphic interpretation of Genesis, theologians engendered Christianity with sexism and patriarchy, both of which have since developed into intricate intersections of oppressions. Religious abuse is founded on the tradition of exclusionary practices and is validated through narrow interpretations of Scripture that work to reassert the authority of the experiences of the dominant culture. The resultant culture of oppression manifests itself in ritualized spiritual violence. Queer people are deemed “unworthy” to take ‘the body and blood of the Christ’ and, in fact, are excluded altogether. This “unworthiness” is expressed as spiritual violence against queer people who are shunned and humiliated, internalize hateful messages, and are denied spiritual guidance or life-affirming messages. By “queering” Scripture, or reading the Bible anew through a framework of justice, queer people have begun to sacramentalize their experiences and reclaim their place at the table.

Biopolymers - facts and statistics

One of the main concerns of this publication is to furnish a more rational basis for discussing bioplastics and use fact-based arguments in the public discourse. Furthermore, “Biopolymers – facts and statistics” aims to provide specific, qualified answers easily and quickly for decision-makers in particular from public administration and the industrial sector. Therefore, this publication is made up like a set of rules and standards and largely foregoes textual detail. It offers extensive market-relevant and technical facts presented in graphs and charts, which means that the information is much easier to grasp. The reader can expect comparative market figures for various materials, regions, applications, process routes, agricultural land use, water use or resource consumption, production capacities, geographic distribution, etc.

Rapid detection of bovine coronavirus by a semi-nested RT-PCR

Bovine coronavirus (BCoV) is a member of the group 2 of the Coronavirus (Nidovirales: Coronaviridae) and the causative agent of enteritis in both calves and adult bovine, as well as respiratory disease in calves. The present study aimed to develop a semi-nested RT-PCR for the detection of BCoV based on representative up-to-date sequences of the nucleocapsid gene, a conserved region of coronavirus genome. Three primers were designed, the first round with a 463bp and the second (semi-nested) with a 306bp predicted fragment. The analytical sensitivity was determined by 10-fold serial dilutions of the BCoV Kakegawa strain (HA titre: 256) in DEPC treated ultra-pure water, in fetal bovine serum (FBS) and in a BCoV-free fecal suspension, when positive results were found up to the 10-2, 10-3 and 10-7 dilutions, respectively, which suggests that the total amount of RNA in the sample influence the precipitation of pellets by the method of extraction used. When fecal samples was used, a large quantity of total RNA serves as carrier of BCoV RNA, demonstrating a high analytical sensitivity and lack of possible substances inhibiting the PCR. The final semi-nested RT-PCR protocol was applied to 25 fecal samples from adult cows, previously tested by a nested RT-PCR RdRp used as a reference test, resulting in 20 and 17 positives for the first and second tests, respectively, and a substantial agreement was found by kappa statistics (0.694). The high sensitivity and specificity of the new proposed method and the fact that primers were designed based on current BCoV sequences give basis to a more accurate diagnosis of BCoV-caused diseases, as well as to further insights on protocols for the detection of other Coronavirus representatives of both Animal and Public Health importance.

The queen is dead-long live the workers: intraspecific parasitism by workers in the stingless bee Melipona scutellaris

Insect societies are well known for their high degree of cooperation, but their colonies can potentially be exploited by reproductive workers who lay unfertilized, male eggs, rather than work for the good of the colony. Recently, it has also been discovered that workers in bumblebees and Asian honeybees can succeed in entering and parasitizing unrelated colonies to produce their own male offspring. The aim of this study was to investigate whether such intraspecific worker parasitism might also occur in stingless bees, another group of highly social bees. Based on a large-scale genetic study of the species Melipona scutellaris, and the genotyping of nearly 600 males from 45 colonies, we show that similar to 20% of all males are workers` sons, but that around 80% of these had genotypes that were incompatible with them being the sons of workers of the resident queen. By tracking colonies over multiple generations, we show that these males were not produced by drifted workers, but rather by workers that were the offspring of a previous, superseded queen. This means that uniquely, workers reproductively parasitize the next-generation workforce. Our results are surprising given that most colonies were sampled many months after the previous queen had died and that workers normally only have a life expectancy of similar to 30 days. It also implies that reproductive workers greatly outlive all other workers. We explain our results in the context of kin selection theory, and the fact that it pays workers more from exploiting the colony if costs are carried by less related individuals.

Circular proteins in plants - Solution structure of a novel macrocyclic trypsin inhibitor from Momordica cochinchinensis

Much interest has been generated by recent reports on the discovery of circular (i.e. head-to-tail cyclized) proteins in plants. Here we report the three-dimensional structure of one of the newest such circular proteins, MCoTI-II, a novel trypsin inhibitor from Momordica cochinchinensis, a member of the Cucurbitaceae plant family. The structure consists of a small beta -sheet, several turns, and a cystine knot arrangement of the three disulfide bonds. Interestingly, the molecular topology is similar to that of the plant cyclotides (Craik, D. J., Daly, N. L., Bond, T., and Waine, C. (1999) J. Mol. Biol, 294, 1327-1336), which derive from the Rubiaceae and Violaceae plant families, have antimicrobial activities, and exemplify the cyclic cystine knot structural motif as part of their circular backbone. The sequence, biological activity, and plant family of MCoTI-II are all different from known cyclotides. However, given the structural similarity, cyclic backbone, and plant origin of MCoTI-II, we propose that MCoTI-II can be classified as a new member of the cyclotide class of proteins. The expansion of the cyclotides to include trypsin inhibitory activity and a new plant family highlights the importance and functional variability of circular proteins and the fact that they are more common than has previously been believed, Insights into the possible roles of backbone cyclization have been gained by a comparison of the structure of MCoTI-II with the homologous acyclic trypsin inhibitors CMTI-I and EETI-II from the Cucurbitaceae plant family.

Influence of ankle functional instability on the ankle electromyography during landing after volleyball blocking

The purpose of this study was to describe, interpret and compare the EMG activation patterns of ankle muscles - tibialis anterior (TA), peroneus longus (PL) and gastrocnemius lateralis (GL) - in volleyball players with and without ankle functional instability (FI) during landing after the blocking movement. Twenty-one players with FI (IG) and 19 controls (CG) were studied. The cycle of movement analyzed was the time period between 200 ms before and 200 ms after the time of impact determined by ground reaction forces. The variables were analyzed for two different phases: pre-landing (200 ms before impact) and post-landing (200 ms after impact). The RMS values and the timing of onset activity were calculated for the three studied muscles, in both periods and for both groups. The co-activation index for TA and PL, TA and GL were also calculated. Individuals with FI presented a lower RMS value pre-landing for PL (CG = 43.0 perpendicular to 22.0; IG = 26.2 perpendicular to 8.4, p < 0.05) and higher RMS value post-landing (CG = 47.5 perpendicular to 13.3; IG = 55.8 perpendicular to 21.6, p < 0.10). Besides that, in control group PL and GL activated first and simultaneously, and TA presented a later activation, while in subjects with FI all the three muscles activated simultaneously. There were no significant differences between groups for co-activation index. Thus, the rate of contraction between agonist and antagonist muscles is similar for subjects with and without FI but the activation individually was different. Volleyball players with functional instability of the ankle showed altered patterns of the muscles that play an important role in the stabilization of the foot-ankle complex during the performance of the blocking movement, to the detriment of the ligament complex, and this fact could explain the usual complaints in these subjects.

Hyperplastic polyps of the colorectum - Innocent or guilty?

Hyperplastic polyps have traditionally been regarded as nonneoplastic polyps lacking malignant potential. The demonstration of genetic alterations within these lesions indicates an underlying neoplastic cause. There is evidence that hyperplastic polyps are heterogeneous. Most are innocuous, but subsets may have malignant potential. Risk factors for neoplastic progression include multiple, large, and proximally located polyps. Aberrant methylation resulting in the silencing of cancer genes may be an important underlying mechanism, particularly in pathways progressing to tumors with DNA microsatellite instability. Lesions intermediate between hyperplastic polyp and cancer include admired polyps and serrated adenomas. Currently, pathologists have different thresholds for diagnosing serrated adenomas, including the distinction from large hyperplastic polyps. Reasons for over looking this pathway in the past may include rapid tumor progression and the fact that proximally located hyperplastic polyps may be flat and not especially numerous. Management of the serrated pathway of colorectal neoplasia may require novel approaches to screening, early detection, and prevention.

The development of a pilot telemedicine network in Scotland: lessons learned

A pilot telemedicine network was established in 11 sites using funding provided by the Department of Trade and Industry in the UK. The main purpose of the project was to develop and evaluate clinical and educational links between central and peripheral sites in Scotland, The results were very encouraging, and clinical services were established in accident and emergency medicine, tele-ultrasound and clinical psychology. An undergraduate medical teaching service was also successfully established. All of these services are to be continued after the completion of the project. Many lessons were learned during the establishment of this network which will be useful in future projects. These included the importance of training for telemedicine users, the importance of identifying a telemedicine champion, the pitfall of health economics and the fact that services must be needs driven.

Sa??de do trabalhador: um (n??o) olhar sobre o servidor p??blico

O presente artigo pretende tecer algumas considera????es a respeito dos discursos e pr??ticas da ??rea da sa??de do trabalhador em rela????o aos trabalhadores dos servi??os p??blicos. Na primeira parte, demarca a constru????o do campo da Sa??de do Trabalhador enquanto pol??tica p??blica no Brasil, identificando como as Confer??ncias Nacionais de Sa??de do Trabalhador trataram o tema da sa??de do servidor p??blico. Em seguida, analisa entrevistas realizadas com profissionais da Per??cia M??dica de um estado brasileiro. Ao final, conclui que a????es voltadas ?? aten????o da sa??de do servidor p??blico n??o integram uma pol??tica p??blica, mas ficam ?? merc?? dos diferentes governos, sendo que os enunciados sobre a sa??de do trabalhador t??m uma fr??gil penetra????o em um campo ainda hegem??nico da medicina do trabalho. A sa??de do servidor p??blico n??o tem merecido investimento, apenas controle, em conson??ncia com um longo hist??rico de desvaloriza????o do setor p??blico.

As reformas administrativas no Brasil: modelos, sucessos e fracassos

O artigo rev??, com base na bibliografia especializada, as reformas e tentativas de reformas administrativas realizadas no pa??s, desde o Estado Novo, passando pelas tentativas dos governos militares e pelas propostas mais recentes da Nova Rep??blica, e chegando at?? a reforma Bresser Pereira. O balan??o cr??tico ?? bastante negativo, sobretudo, porque as grandes reformas, precisamente pela sua abrang??ncia, nunca foram efetivamente implementadas. O sistema do m??rito no servi??o p??blico federal ?? um bom exemplo. As dificuldades de implementa????o das grandes reformas, advindas principalmente de sua grande complexidade, resultam tamb??m de sua intera????o negativa com o contexto pol??tico mais geral, pela carga ret??rica de que se fazem acompanhar, e pelo fato de subestimarem os aspectos t??cnicos necess??rios ?? sua implementa????o.

As políticas de proteção social no contexto escolar

Esta dissertação teve o objetivo de investigar como a formalização das políticas de proteção social via programas e projetos socioeducativos se articulam com a educação escolarizada. Realiza uma discussão conceitual acerca das políticas de proteção social e “vulnerabilidade e risco social” a partir de aspectos históricos situando-as na lógica societária das desigualdades e complexificações das refrações da questão social do modelo capitalista de produção e reprodução social, sobretudo no contexto das reformas do Estado brasileiro enquanto demanda dos ajustes neoliberais. O lócus da pesquisa foi uma escola da rede pública municipal de Serra/ES. As investigações foram realizadas em duas etapas. A primeira constituiu-se de um estudo exploratório de caráter qualitativo. Por meio das análises abstraídas dessa fase, foi realizado um estudo de caso como segunda etapa da pesquisa. Os instrumentos utilizados, análise de documentos, observação participante e entrevistas, evidenciam que os programas e projetos socioeducativos desenvolvidos no espaço escolar visando a uma suposta proteção social, não guardam relação concreta com a melhoria dos processos de aprendizagem dos alunos, logo, seus efeitos na vida escolar desses alunos não foram evidenciados. Verificou-se ainda profunda desarticulação entre as propostas pedagógicas da escola e dos docentes com os programas e projetos investigados. A partir dos dados da pesquisa, pudemos ainda constatar que tais programas e projetos adentram o espaço escolar por meio de demandas externas envolvendo a Secretaria Municipal de Educação e a iniciativa privada. Concluímos que a proteção social no espaço escolar via programas e projetos socioeducativos necessita voltar-se à articulação com políticas públicas que ultrapassem os muros da escola e que de fato garantam o acesso a bens materiais e simbólicos com vista à melhoria das condições de vida material e sociocultural dos alunos a quem são destinados e, consequentemente, a melhoria da qualidade da educação escolarizada.
