Tapoyo, Vanessa. "La spiritualité perçue comme un facteur de performance du leadership dans les organisations : cas des dirigeants en France et au Gabon." Thesis, Montpellier 3, 2019. http://www.theses.fr/2019MON30005.
Full textThe contemporary society is in permanent evaluation in a speed always more greater, a competition always stronger and creating more and more a faintness at the people with responsibility who work in an atmosphere of big uncertainty, of loss of humanity and marks. For the leaders today, the challenge is to find the peace, serenity and confidence in the work every day; to find alternatives for their good to be and has to better yield one their leadership. It is by this way that intervenes the spirituality. This search highlighted the way the spirituality participates to improve and to maint performance of the leadership in organizations. By the construction of a theory of the Including Spiritual Leadership, we understand why, how and in which purpose the spiritual intervenes in the life of the managers/leaders. The spirituality appears as engine of efficiency of the leadership of the managers/ leaders, essentially by a report to one, to the otherness, to the belief, to the transcendent, to the religious order and to the faith. It is « the ascendancy of the spirit on the body ». The manager/leader finds in the spirituality a frame to think and of action which through by the sense, the introspection, the optimism and the confidence. The leader takes example and embodies the example, he is less vulnerable and more productive. His « spiritual competence » influences its choices, its state of mind and its interactions, allowing him to go at the end of its realizations through « love » of « others »

Full textStarting from the idea that externalisation practices allow companies to make higher profits, the research aims to identify the special arrangement and mechanisms within buyer-seller relationships likely to create value for the partners in a context of international trade Indeed, multiculturalism is at the heart of cooperation; yet this dimension is often left out, taken for granted, as if common objectives were beyond these differences of point of view and beyond the management of collective action or as if the common technical knowledge led to a natural dialogue between pairs. In order to determine the mechanisms likely to create value for the partners, I have shown that a long term orientation is an indicator of the quality of the cooperation, since it implies that the partners are getting benefits from their cooperation. Then, I have referred to the fundamental theories of cooperation, that is to say the Transaction Cost Theory and the Social Exchange Theory but also based my analysis on dyadic and network approaches, in order to bring out (or more precisely isolate) four key mechanisms in value creation: trust, satisfaction, communication and equity. In order to study the means of contextualisation of this general pattern, I have tested its validity in the specific field of tourism in Cameroon through a quantitative survey, then by applying the theories of multiculturalism and through case-studies, I have tried to name the main contingency factors of the long-term orientation and their impact on the relational mechanisms identified namely: trust, communication, satisfaction and equity. More generally, this research can be understood as a tribute to the study of the methodological implications of cooperation theories. It opens perspectives in Business to Business Marketing and in International Marketing. It suggests a framework to implement it in specific contexts. It leads to further developments concerning the issue of multiculturalism in B to B cooperation

Full textSince the seminal work of Gary Becker and Theodore Schultz in the 1960s, the concept of human capital is still of great interest in academia. It is widely held that human capital is a source of value creation for individuals, firms and nations. At firm level, the concept of human capital deals with both internal production issues and those related to corporate governance. The aim of this thesis is to analyze the involvement of human capital on corporate performance and competitive advantage. We develop two essential dimensions that constitute the two parts of this thesis.In the first part, we examine the effects of human capital involvement on performance and competitive advantage in the banking sector. The chapter 1 examines the strategic challenges of human capital in the banking sector and reviews the empirical literature on the measurement of human capital. The chapter 2 suggests a measure of specific human capital and tests its impact on the performance and competitiveness of a regional bank branches. The results highlight a positive and significant impact of the specific human capital at individual level and at branch level as well as on the competitive advantage of branches.In the second part, we focus on employee ownership as mechanism by which the firm-specific human capital development process can be stimulated and protected. The chapter 3 analyzes the role of human capital intensity and governance factors in the implementation and progression of employee ownership in a sample of French companies listed over the period 2000-2014. The results showed that firms that are intensive in human capital have a higher probability of the implementation of employee ownership scheme. The results also showed the impact of governance factors, in particular, related to entrenchment mechanism on the development of employee ownership. The chapter 4 analyzed the impact of "significant" employee ownership, i.e. the impact of major number of employee presence in the capital. The econometric results revealed a negative effect of significant employee ownership on the economic performance of companies; this effect is reinforced by the presence of employee directors in the board

Full textThis thesis deals with the modeling and simulation of the Integer-N PLL circuits for the purpose of an accurate and quick design verification. The main PLL verification issues such as steady-state response, random/deterministic noise, and dynamic performances are involved, and the objective is to provide new algorithms and models which allow the prediction of the main characteristics of the PLL with the same precision of the transistorlevel simulation using much less simulation time. First, concerning the calculation of the PLL steady-state response, we carefully consider the block interfaces loading conditions and propose a rigorous iterative algorithm which allows achieving a good precision and a quick simulation convergence. Then, to predict the phase noise and deterministic noise of the PLL, block-level models for the PLL building blocks are brought forward, based on the obtained steady state response. Finally the analysis of the PLL dynamic performances is studied. We propose a modeling methodology for various blocks which can achieve an enormous simulation speed-up with a precision comparable with the transistor-level simulation

Full textLean is an approach aiming at eliminating non-value added operations, used by companies to improve the performance of their production activities. Companies applying this approach are observing rapid gains in operational terms but gradually some observe a fall in operating results or a degradation of the health of work force. We seek to overcome these limits and we ask about the ability of those of the company to anticipate and to take corrective actions. For this, we question about the performance model and the decision adopted by corporate actors to deploy Lean. We propose thatcorporate actors evaluate the efficiency of production, processed by the Lean approach, taking into account not only the operational level of performance, but also the human dimension integrating realwork activity. We define a performance model that supports a kind of “actor” vision of man at work.To help corporate actors to change their existing model of Lean performance, we offer a support methodology based on a reengineering approach integrating coaching aimed at changing there presentations of the actors by a sociocognitive learning. This methodology is based on a framework and modeling tools to represent the impacts of this new performance model on the decision and on the sustainability of the lean benefits

Full textMany specialists have shown interest in the values tha sport can convey in a company. However, few analysed the skills and abilities gained by a high level sportsman in their career and what this can bring to their managment within an organisation. Within the context of perpetually changing global environment executives are constantly looking for ways in which to gain further developement from their human capital in order to guarantee the success of the firm. It is therefore interpersonal skills rather than well practised managemnt techniques that are a distinguishing factor. An important theoretical debate concerns the acquisition of "managerial skills". The multiplication of qualifications shows the importance of an academic training to gain managerila skills. However, such a necessity has been brought into question by such eminent managment theoreticians as Mintzberf. He argues that managment requires first and formost interpersonal skills which are important as technical skills. However, it is difficult to indoctrinate implicit knowledge and emotional intelligence through one universal method of leraning. Whitin this persperctive the question remains as whether the type of educion received in high level sporting competition can compensate for deficiencies from academic education. Our thesis therefore is a reflection that has been studied very little in an academic sense and will lead us to develop an emprirical method, firstly through the creation of a questionnaire to gain access to the experts opitions and the to apply the methodology DELPHI, which is particulary well adapted to construct the beginnings of a discussion in a field which has so far had too little attention in scientific work

Full textThis work aims at understanding hope’s beneficial effects in physical and sports activities. After ensuring the viability and sustainability of Snyder’s hope model (Snyder et al., 1991, 1996) through a validated measurement tool, we tried to identify how hope contributes to success in physical education at school, and hope’s beneficial effects on students’ performance and resilience during a cycle ergometer session. The experimentation results prove Snyder’s hope model reliability from an empirical viewpoint, despite the reservations about its theoretical validity. In a school context, trait hope enables to predict their cycle-end grades, through a mediation of state hope and perceived ability. This data corroborates the existence of a hierarchical model in the concept of hope. Furthermore, hope can also be associated to better performance in experimental situation, after receiving a failure feedback. By having a protective effect on the result perception, hope offers a better resilience, immediately after the feedback. Thanks to the diversified contexts and methods, our research brings light on hope’s effects and consequences in physical and sports activities, and more generally speaking, on the relevance of this yet unknown theory that should be developped and extended to other study populations and contexts

Full textRésumé : Les poutres profondes en béton armé (BA) sont couramment utilisées comme poutre de transfert ou coude de pont, comme quoi sa sécurité est souvent cruciale pour la sécurité de l’ensemble de la structure. Ces éléments sont exposés à un environnement agressif dans les climats nordiques causant des problèmes de corrosion de l’acier en raison de l’utilisation excessive de sels de déglaçage. Les polymères renforcés de fibres (PRF) sont apparus comme des matériaux de renforcement non corrodant pour surmonter ces problèmes dans les BA. La présente étude vise à examiner la question de l'applicabilité des poutres profondes en béton complètement renforcées de barres en PRF. Dix poutres profondes à grande échelle avec des dimensions de 1200 × 300 × 5000 mm ont été construites et testées jusqu’à la rupture sous chargement en deux points. Les variables testées comprenaient différents ratios de cisaillement porté/profondeur (égal à 1.47, 1.13 et 0.83) ainsi que différentes configurations d’armature dans l’âme (incluant un renforcement vertical avec ou sans renforcement horizontal). La rupture de tous les spécimens a été précédée par l’écrasement du béton dans le mât diagonal, ce qui est la rupture typique pour les poutres profondes en BA. Les résultats ont révélé que toutes les configurations de renforcement de l’âme employées dans les spécimens d'essais avaient un effet négligeable sur la résistance ultime. Toutefois, la résistance des spécimens contenant uniquement un renforcement horizontal était étonnamment inférieure à celle des spécimens sans renforcement. La contribution principale du renforcement de l’âme était dans le contrôle de la largeur de fissuration. Les spécimens examinés présentaient une déflexion raisonnable par rapport à ce qui est disponible pour les poutres profondes renforcées en acier dans la littérature. Le développement de l'effet d'arche a été confirmé par la distribution quasi uniforme des déformations le long du renforcement longitudinal dans tous les spécimens. En outre, l'hypothèse de base du modèle des bielles et tirants (MBT) a été utilisée adéquatement pour prédire la distribution de déformation le long du renforcement longitudinal, confirmant l'applicabilité du MBT pour les poutres profondes armées de PRF. Par conséquent, un modèle basé sur un MBT a été proposé afin de prédire la résistance des poutres profondes renforcées de PRF en utilisant les données expérimentales en plus de la mise à l'épreuve expérimentalement des poutres profondes renforcées de PRF trouvées dans la littérature. Une évaluation des MTB disponibles dans les dispositions des codes a été menée afin de déterminer les paramètres importants affectant le facteur d'efficacité de la bielle. La tendance de chaque paramètre (la résistance à la compression du béton, le ratio de cisaillement porté/profondeur, et la déformation dans le renforcement longitudinal) a été évaluée individuellement contre le facteur d'efficacité. Des calculs basés sur l’énergie des déformations ont été effectués pour identifier le modèle de treillis approprié afin de détailler les poutres profondes renforcées de PRF. Par conséquent, seulement quatre spécimens avec un renforcement vertical dans l’âme présentaient la formation de modèles avec deux panneaux de treillis. Le modèle proposé a été capable de prédire la capacité ultime des poutres profondes testées. Le modèle a également été vérifié contre une base de données de 172 poutres profondes renforcées en acier aboutissant en un niveau acceptable de pertinence. La capacité ultime et la performance des poutres profondes testées ont été également adéquatement prédites employant un programme d'éléments finis en 2D (VecTor2), ce qui fournira un puissant outil pour prédire le comportement des poutres profondes renforcées de PRF. L'analyse non linéaire par éléments finis a été utilisée afin de confirmer certaines hypothèses associées à l'étude expérimentale.

Full textWhy do some high-tech start-ups succeed and others do not ? This question on the performance of high-tech start-ups has received much attention in recent literature and practitioners' discussions. Prior literature has treated the question mainly in two ways: (1) by building holistic qualitative frameworks and (2) by building partial quantitative models. However, in order to make performance predictions these two approaches need to be brought together in a holistic and quantitative framework. The present study addresses this gap by exploring alternative mathematical methods for the prediction of the global prospects of high-tech start-ups, as well as for their investment readiness. For this purpose, prior literature on new venture performance is reviewed. The present study integrates the diverse prior results by the proposition of an alternative integrative framework. It is furthermore proposed that such a framework should integrate non-linear relationships. Three alternative research methods - linear multiple regression, cluster analyses, and Fuzzy Theory analyses - were carried out on a sample of 124 European high-tech start-ups. Comparison of the three methods suggests that an integrative framework is quantified best by Fuzzy Theory. First, the fuzzy models show substantially superior accuracy of the performance predictions over regression and cIuster analyses. Second, their generalizability and predictive power exceed those of the statistical methods. It is therefore shown that alternative analytical methods may improve the predictive power of entrepreneurial models. The results of the present study confirm that performance can be explained best by a holistic view. Ln fact, performance is predicted best by models (1) involving salient factors from ail high-tech start-up domains; (2) involving interactions between ail salient factors; and (3) involving non-linearities of the performance relationships. The results are transferred onto the practical terrain by the development of a hightech start-up diagnostic tool- the Venture Coach. The study advances entrepreneurship theory and has important implications for the practical terrain

Full textThe filter technologies, resonators, oscillators and sensors are essential elements fortelecommunications, automotive, military, medical industries. The most of radio frequency surface acousticwave (RF-SAW) filters, present in mobile phones, are based in LiNbO3 (LN) and LiTaO3 (LT) single crystalsbecause they have high electromechanical coupling factor (K2). However, these materials have a problemrelated to the variation of the operating frequency with temperature (TCF), whose value is about -40 to -95ppm / ° C. On the other hand, it has been previously shown in the literature that the physical and structuralproperties of LT and LN change with Li non-stoichiometry, including elastic properties.The aim of this work was the investigation of the impact of Li2O concentration on the performance ofSAW devices based on YXl/42 (42 RY-LT) and YXl/128 (128 RY-LN) single crystals. In the case of 42 RY-LT,we focused in the reduction of TCF without the degradation of other properties (K2 and insertion losses) andin the case of 128 RY-LN crystals we focused in the stability of devices at high power densities. First, singlecrystals of LT and LN with different Li2O concentration: 48.5-50 ml% were prepared, by using the VaporTransport Equilibration (VTE) method. Afterwards, SAW and bulk acoustic wave (BAW) devices based on LTand LN VTE treated crystals, were fabricated and characterized, in order to study the effect of Li nonstoichiometryand the effect of ferroelectric domains on the performance of devices

Full textThis thesis explains and clarifies the ways in which responsible performance can increase financial performance for investors. Based on data gathered between 1992 and 2012 and a state-of-the-art KLD scoring system, we demonstrate that Corporate Social Responsibility (CSR) does not consistently increase the performance of a share portfolio. CSR, when proactively implemented, proves to be a cost granted by investors concerned about their ethical models. Depending on the sector observed, restrictions on irresponsible acts can however improve financial performance. Our research highlights the importance of selecting portfolio assets beforehand. We found that CSR strategies improve financial performance provided that some criteria which restrict managerial opportunism. Our multi-criteria analysis revealed that the expenditure of responsibility is a result of excess cash flow. The weighted average cost of the debt will determine the effectiveness of these strategies on the company's profitability. Finally, we highlight discrepancies in Corporate Social Responsibility reports, according to the ethical level and financial performance of each company. These lexical fields inform the investor of managers’ intentions and hence, allow a better selection of the assets

Full textHigh Performance Computing is preparing the era of the transition from Petascale to Exascale. Distributed computing systems are already facing new scalability problems due to the increasing number of computing resources to manage. It is now necessary to study in depth these systems and comprehend their behaviors, strengths and weaknesses to better build the next generation.The complexity of managing users applications on the resources conducted to the analysis of the workload the platform has to support, this to provide them an efficient service.The need for workload comprehension has lead to the collection of traces from production systems and to the proposal of a standard workload format. These contributions enabled the study of numerous of these traces. This also lead to the construction of several models, based on the statistical analysis of the different workloads from the collection.Until recently, existing workload traces did not enabled researchers to study the consumption of resources by the jobs in a temporal way. This is now changing with the need for characterization of jobs consumption patterns.In the first part of this thesis we propose a study of existing workload traces. Then we contribute with an observation of cluster workloads with the consideration of the jobs resource consumptions over time. This highlights specific and unattended patterns in the usage of resources from users.Finally, we propose an extension of the former standard workload format that enables to add such temporal consumptions without loosing the benefit of the existing works.Experimental approaches based on workload models have also served the goal of distributed systems evaluation. Existing models describe the average behavior of observed systems.However, although the study of average behaviors is essential for the understanding of distributed systems, the study of critical cases and particular scenarios is also necessary. This study would give a more complete view and understanding of the performance of the resources and jobs management. In the second part of this thesis we propose an experimental method for performance evaluation of distributed systems based on the replay of production workload trace extracts. These extracts, replaced in their original context, enable to experiment the change of configuration of the system in an online workload and observe the different configurations results. Our technical contribution in this experimental approach is twofold. We propose a first tool to construct the environment in which the experimentation will take place, then we propose a second set of tools that automatize the experiment setup and that replay the trace extract within its original context.Finally, these contributions conducted together, enable to gain a better knowledge of HPC platforms. As future works, the approach proposed in this thesis will serve as a basis to further study larger infrastructures

Full textHypodynamia-hypokinesia is a condition in which the motor activity (hypodynamia) as well as the weight exerted on the lower limbs (hypokinesia) are reduced. In humans, this condition is induced in immobilization, bed-rest, spaceflight or ageing (immobility syndrome) and is characterized by a chronic reduction in neuromuscular activity. This hypoactivity results in a profound alteration of motor task performances, in particular posture, gait and locomotion. These impairments are due to alterations in the muscular system (atrophy, phenotypic changes), but also to plastic changes in neural functions (cortical reorganization, alterations in cortical excitability, morphologic modifications). While degradation of the muscular system is described in the literature, the mechanisms involved in cortical plasticity are still unclear. A better understanding of the systems involved in hypodynamia-hypokinesia would allow the development of preventive and / or recovery strategies for patients affected by this hypoactivity. In this regard, hindlimb unloading is a disuse rodent model in which the elevation of the hindlimbs, during 14 days, prevents the weight to be normally exerted on the hindlimbs and reduces the normal muscular activity, finally causing hypoactivity. Studies performed on this model have shown that hindlimb unloading and human hypoactivity have similar effects. Today, our interest is turned towards insulin-like growth factor 1 (IGF-1), a ubiquitous protein involved in many cerebral functions. Indeed, IGF-1 is known to improve, inter alia, angiogenesis, neurogenesis and to be involved in synaptic plasticity in the whole brain. Moreover, several publications suggest that IGF-1 might mediate the beneficial effects of exercise on the brain.The aim of this study is to characterize the role of IGF-1 in cortical reorganization induced by hindlimb unloading as well as its functional consequences on motor performance. In the first part of the study, we have determined the effects of hindlimb unloading on IGF-1 level and the impact of its downstream main molecular pathways in motor control (sensorimotor cortex, striatum, cerebellum). Our results indicate that hindlimb unloading induces a decrease in IGF-1 level specifically in the sensorimotor cortex. This alteration is associated to a decrease in activation of the PI3K-AKT pathway. The second part of this study is dedicated to the effects of a restoration of IGF-1 levels, during the whole unloading period, on cortical reorganization and behavioral alterations focusing on sensory cortex and tactile sensory discrimination as well as motor cortex and motor performances. Our results show that treatment with IGF-1 partially prevents cortical reorganization and degradation of tactile sensory discrimination. Additionally, it appears that restoration IGF-1 levels prevent some of the effects of hindlimb unloading on the motor system.Taken together, ours results suggest that the decrease in the level of IGF-1 in the sensorimotor cortex during hindlimb unloading plays a key role in the cortical reorganization induced by hypoactivity. Moreover, our study shows that the prevention of this cortical reorganization, even when partial, can induce functional improvement in motor performance

Full textThis thesis presents a research model that contributes to a better understing of the performance of small and medium business. Specifically, answers are sought to the following questions : How can we explain the differences in the observed economic performance of small and medium business ? Why do entrepreneurs seek to achieve differents objectifs or goals through business ownership ? The proposed model is composed of several variables : orientation of the entrepreneur in terms of his motivations and competencies as measured by the importance attributed to his objectifs and competencies, criteria of performance valued by the entrepreneurs in evaluating the success of their business, family responsabilities, professional experience and individual characteristics (age, gender, education level, marital status). The entrepreneurial performance is the last dimension of the model and is the result of the interaction of all of the other variables in the model. .

The method used, called Equimetrix, is based on the measurements of accelerations at a point near the center of gravity of the horse. The main advantages of that method are an easiness of use in the field and a fast obtention of biomechanical data. The locomotor test presented here allows the quantification of a great number of gait variables. Their reproducibility is shown as well as theirs main factors of influence : speed, age/training status, level of performance. Relationships between physiological and gait data are described, as well as the heritability of locomotor variables
Balducci, Pascal. "La place du coût énergétique dans les facteurs de performance en trail running." Thesis, Lyon, 2017. http://www.theses.fr/2017LYSE1043.
Full textTrail running is a discipline with increasing popularity over the last 2 decades. Trail performance depends on many genetic, energetic, technical, strategic and motivational factors. Among these factors, the energy cost of locomotion is debated. The studies in this Thesis focus on the level/graded correlations of this variable, on the calculation of an uphill cost from a level cost, on the influence of a forced modification of stride frequency on running economy, and on the impact of fatigue generated by an ultra trail on level and uphill costs. Taking account of the muscular and biomechanical constraints on the one hand, and the factors influencing the running economy on the other hand, as well as the results of our main field study, we hypothesize that energy cost and its pre/post fatigue variations, are not performance indicators of the activity. Force, endurance of force and pacing, in addition to aerobic power and endurance, are the tested variables best correlated to ultra trail performance

Full textThe aeronautical field is clearly a complex system; a complexity that should be extended in the coming years with the increased traffic and the autonomy diversification of the aircraft. The complexity is embedded in the technological systems design in order to enable the operators to define in an effective, efficient and satisfactory way a solution facing challenges posed by the complexity of the reality on their performance and safety. These properties are those of a system that we name here simplex. Nevertheless, the current available methods in ergonomics to assess Human-Simplex System Interactions (HSSI) are limited face the Human Oriented Approach of Complexity. In this regard, we focused on the development of ergonomic criteria in support of the human factors specialists’ diagnosis task. The criteria definition followed a user-centred design process by involving 4 Human Factors specialists from the industrial and university sector throughout the whole design and assessment process. A primary version has been built by following the Grounded Theory methodology. Then, the criteria have been successively updated after 3 assessments. Two studies focused on the usability level of the criteria. They were based on an assignment task of aeronautical problems to the elementary criteria proposed. A study focused on the reliability and valid level of the criteria to identify problems. It was based on an inspection task carried out with an aeronautical concept and a system from the general public. The set of these studies has been performed with 39 Human Factors specialists and 22 engineers involved in Human Complex System Interactions This work led to the development of 26 elementary criteria dealing with the adaptability properties of the system (i.e., adapted and adaptive).

Full textThe aim of this work was i) to validate a method to calculate force during bench press exercise according to data obtained with a kinematic device; ii) to relate the muscle characteristics of the upper and lower limbs of throwers (discus, hammer and shot-put) to the performance; and iii) to propose a protocol adapted to throwers’ evaluation. Firstly, forces calculated according to data obtained with a kinematic device during bench press exercise were compared to those simultaneously measured with a force platform. The results showed the importance of taking the upper limbs mass into account when forces are calculated using a kinematic device. Secondly, muscular characteristics of the upper (maximal power, force and velocity determined from bench press exercise) and lower limbs (maximal power, force and velocity determined from half squat exercise and musculotendinous stiffness) were analyzed in a group of high level male throwers. Whatever the throwing events considered, results demonstrated that throwing performance was associated on the one hand with high lower limb strength and a high level of leg stiffness, and on the other hand with a upper limbs maximal power. Finally, force, velocity and power determined during cycling and those obtained from half squat exercise were compared. From a quantitative point of view, power, force and velocity values determined during cycling were significantly different. However, the same relationships between muscular characteristics and throwing performance were evidenced. In line with previous analysis the following testing protocol could be suggested: half-squat 1-RM (one repetition maximal) and musculotendinous stiffness determination for lower limbs, and maximal power estimation from one bench press against a barbell without load for upper limbs

Full textOur aim was to show that self-description in personality inventories communicate individuals' self-knowledge about their social value. Following social judgment framework, social value is defined around two fundamental dimensions: social desirability and social utility. The former refers to the individuals' reputation to elicit positive affects in interpersonal relations. The latter refers to the individuals' reputation to perform in social systems. We postulated that self-description in personality inventories rely more on the social utility and social desirability of the items (evaluative information) than on the personality factors they are supposed to measure (descriptive information). We first showed that personality items could cover more or less social desirability or social utility. Then, we showed that these two components serve the malleability of self-descriptions according to explicit or implicit social exigencies. In a third set of studies, we studied the role of descriptive and evaluative information on performance inferences. Results showed the primacy of evaluative over descriptive information for professional performance inferences. Finally, the last two studies show that personality factors predict performance primarily through the items whose social value is congruent with the value mobilized by the performance criterion (selection, social relations). Taken together, the results support our hypothesis and indicate that individuals express an intuitive knowledge of their social value in personality inventories

Full textCreated by americans and developed by japanese, quality circles arrived in France in the begining of the 80s. Their aim, owing to the mobilization of participants intelligence, consists in improving the quality of products, the productivity and costs, and the satisfaction of participants which corollary is the decline of absenteeism and turnover. The impact of quality circles on the performances of unities in which they are grafted has been rigorously studied, more particular in the United States. These studies show that, whatever the methodology used, one find out sometimes performance improvements, sometimes almost nothing. Therefore, in some cases quality circles induce performance improvements and in others they don't. The aim of this research was precisely to determine the profile and characteristics of the context in which quality circles have high performances. An exploratory study based on 25 firms belonging to different activity sectors, and an analysis of collected data on a sample of 206 quality circles in industrial environment show that the performances of a circle are high in the quality circles comprising 5 to 12 members, an age ranging from six months to five years, and they belong to firms having the following characteristics : a thorough preparation of organization according to quality circles approach, an active support and middle management involvement, a commitment and visible support of the top management, a participative management. .

Full textExport performance of the small entreprise, calculated by export on sales ratio is a reality which shows that the size is not a discriminating factor against export. That performance is bound to the quest for market power which derives from specialization, that is to say, from the whole of the competences, and from the industrial organisation in which these entreprises find themselves. In fact, because of an uncertain environment, the large firms have developed an industrial organization in terms of flexibility and networks that include the small entreprises through the relations of association and competition. When the abilities of the small entreprises from efficient organization of production or work processes, this means that, from an industrial specialization, their association relationships with large entreprises corresponds to oligopsony. Small entreprises export is made by concerted forms and international subcontractor concluded by the large entreprises. It will depend on their competencies and the market potentialites. If their competencies are related to a product, to a custom, to the possession of technology, that is to say, to a marrowed specialization; their relationships, with the large entreprises are competitive; and their export depends on their will but also on the

Este trabalho tem como objetivo observar a possível relação teórica entre grupos estratégicos da indústria automobilística brasileira e o desempenho das empresas pertencentes a estes grupos estratégicos. Para cumprir este objetivo, foram analisadas 30 montadoras de automóveis, identificando os grupos estratégicos formados, utilizando a tipologia de Michael Porter como base. Após a identificação das estratégias competitivas foi realizada análises sobre o desempenho dos grupos, observando como os grupos estratégicos se apresentam dentro desta indústria. Os dados foram analisados estatisticamente (Z-score, Shapiro-Wilks, análise fatorial, K-means clusters, ANOVA e MANOVA), permitindo análises mais consistentes sobre o coalinhamento estratégico das empresas da indústria em questão. Como resultados, foram encontrados cinco grupos estratégicos, com diferenças significantes entre os seus desempenhos médios para algumas variáveis dependentes, especialmente para a variável Satisfação dos clientes. Esta diferença entre o desempenho médio dos grupos estratégicos indica a importância do estudo das estratégias competitivas das empresas de determinada indústria, sugerindo possível relação teórica entre a estratégia e o desempenho.
This study aims to evaluate the possible theoretical relationship between strategic groups of the Brazilian automobile industry and the performance of companies belonging to these strategic groups. To achieve this goal, were analyzed 30 car assemblers companies, identifying strategic groups, using Michael Porter s typology as a base. After the identification of competitive strategies, analysis was conducted on the performance of the groups, observing how the strategic groups present within this industry. Data were statistically analyzed (Z-score, Shapiro-Wilks, factor analysis, K-means clustering, ANOVA and MANOVA), allowing more consistent analyzes of the strategic co-alignment of industry companies concerned. As a result, five strategic groups were found, with significant differences between their average performances for some dependent variables, highlighting the Consumer Satisfaction variable. This difference between the average performances of strategic groups indicates the importance of studying the competitive strategies of the particular industry companies, suggesting a possible theoretical relationship between strategy and performance.

Full textThe present thesis fits on the border of muscle physiology and biomechanics. Three studies investigated the factors influencing the relationship between vertical jump (DV) and maximal power out on cycle ergometer (Pmax). Study A, conducted on 106 participants from two groups (volleyball players, VB, and physical education students (PES) without specific training in jumping or cycling exercises) including 67 Caucasian (C) 39 West African (WA) origins, showed significant effects of sports practice (VB>PES) and enthnicity (E) (WA>C) on countermovement jump with arm swing (CMJA). However, the difference in Pmax was not significant between groups. The CMJA-Pmax relationships were different in C and WA (P=0.003). Therefore, CMJA predicted from Pmax would be underestimated in WA. The same difference was observed for CMJA-PmaxArms relationship. Study B, conducted on 84 participants, showed E significant difference (WA>C) in DV on a force platform in squat jump (SJ), countermovement jump (CMJ), CMJA, CMJA-CMJ, CMJA/CMJ. The effect sizes of E were large for CMJA, CMJA-CMJ, CMJA/CMJ and medium for CMJ and SJ. E effect of countermovement jump (CMJ-SJ) was not significant. In study C, the effects of anthropometric factors [body height (BH), sitting height (SH), foot length (FL), leg length (LL), Body Weight (BW), BMI, Body fat (BF), BF/BW and Skelic (Sk=LL/SH) or Cormic (Co=SH/BH) indices], and E (C vs WA) on SJ, CMJ and CMJA)] have been measured on a force platform in 55 PES [32 Caucasians (group C) and 23 West-Africans (group WA)]. Only SH, Sk and Co were significantly different in C and WA. All DV performances were higher WA The ethnic difference in SH could partly explain the higher DV values in WA
