Comprendre ce qui amène un leader à émettre des comportements de leadership transformationnel fascine les chercheurs et praticiens depuis plusieurs années (Bommer, Rubin, & Baldwin, 2004; Bono & Judge, 2004; Shamir & Howell, 1999 ; Stogdill, 1948; Yukl, 1999). Or, jusqu’à présent, ces facteurs sont encore bien peu étudiés et compris comparativement aux conséquences de ce style de leadership. Dans cette lignée, la présente thèse répond à différents enjeux soulevés par les auteurs à ce sujet (Dinh & Lord, 2012; Zaccaro, 2007) en cherchant à préciser le rôle joué par différents antécédents individuels et contextuels du leadership transformationnel. Cet objectif sera poursuivi par l’adoption d’une perspective interactionniste qui intègre des antécédents de personnalité et de contexte ainsi par l’évaluation de la personnalité à l’aide d’une modélisation de la personnalité orientée vers le critère à prédire (variable composite). La présente thèse est composée de trois articles poursuivant les objectifs suivant : 1) Effectuer une synthèse de la littérature empirique portant sur les antécédents individuels et contextuels du leadership transformationnel; 2) Vérifier les liens empiriques entre la personnalité mesurée à l’aide de variables composites, plus précisément le modèle des Great Eight de Bartram (2005), et le leadership transformationnel; 3) Tester empiriquement l’effet d’interaction entre les variables de personnalité et les variables contextuelles pour prédire le leadership transformationnel. Le premier article vise d’abord à circonscrire et organiser les connaissances empiriques actuelles provenant d’une quarantaine d’articles concernant les antécédents du leadership transformationnel. L’article s’organise en trois thèmes principaux : les antécédents individuels de personnalité, les antécédents contextuels et l’étude des interactions entre le volet individuel et contextuel. Plusieurs constats et pistes de recherches sont discutés et mettent la table pour les deux articles subséquents. Ainsi, le second article s’intéresse au potentiel explicatif d’un modèle de personnalité orienté vers le critère pour prédire le leadership. Plus spécifiquement, le modèle des Great Eight proposé par Bartram (2005) est mis en relation avec les comportements de leadership transformationnel et de récompense contingente. Les résultats, obtenus auprès de 113 gestionnaires et de leurs 799 subordonnés, donnent peu d’appui à la valeur ajoutée du modèle utilisé, mais indiquent que certaines tendances de personnalité sont associées au leadership. Des analyses supplémentaires permettent de nuancer la compréhension des effets observés dans la documentation scientifique et offrent quelques pistes de groupements de traits pouvant prédire les différents comportements de leadership. Le troisième article s’inspire de la théorie de l’activation des traits (Tett & Burnett, 2003) pour vérifier l’effet combiné de la personnalité du gestionnaire et du contexte dans lequel il évolue en vue de prédire le leadership transformationnel. Les résultats (ngestionnaires = 89; nsubordonnés = 643) n’offrent qu’un appui modéré au rationnel sous-jacent du modèle de l’activation des traits. Toutefois, il en ressort que l’aspect relationnel du gestionnaire (opérationnalisé par le composite de personnalité « soutien et coopération ») est associé à l’émergence du leadership transformationnel uniquement lorsque les facteurs contextuels (considération organisationnelle, latitude décisionnelle) sont perçus positivement par le gestionnaire. L’étude permet donc d’éclaircir une part de la variabilité observée dans les études antérieures concernant la tendance relationnelle du gestionnaire, en soulignant sa sensibilité à des facteurs contextuels positifs. / Understanding what can influence a leader to demonstrate transformational leadership behaviours has intrigued researchers and practitioners for several years (Bommer, Rubin, & Baldwin, 2004; Bono & Judge, 2004; Shamir & Howell, 1999; Stogdill, 1948; Yukl, 1999). Yet, until now, these factors were little researched and poorly understood in comparison to the consequences of this type of leadership. Along these lines, this thesis answers to numerous issues raised by authors on this topic (Dinh & Lord, 2012; Zaccaro, 2007) by seeking to clarify the role of different individual and situational antecedents of transformational leadership. This objective is pursued through the adoption of an interactionist perspective which integrates individual and contextual antecedents to the assessment of personality supported by a criterion-centric personality model (compound variable). This thesis is composed of three articles that pursue the following objectives: 1) Review empirical literature on individual and contextual antecedents of transformational leadership; 2) Validate the empirical links between a new personality model (i.e. compound variable) and transformational leadership; 3) Test empirically the correlations between personality and contextual variables to predict transformational leadership. The first article aims to review and organize the current empirical knowledge from more than forty articles regarding transformational leadership indicators. The article is built on three major themes: the individual personality factors, the contextual elements and the study of the interaction between both. Multiple findings and research leads are discussed and set the stage for the following articles. In turn, the second article investigates the explanatory potential of a criterion-centric personality model to predict leadership. Specifically, the Great Eight model, put forward by Bartram (2005) is leveraged to understand the relationships between behaviours tied to transformational and transactional leadership. Results from a survey of 113 managers and their 799 subordinates provide little support for the explanatory value of this model, but indicate that some personality traits are associated with leadership. Further analysis allows us to put the results in perspective with the academic literature and provide some insights regarding the potential for some personality trait groupings to predict leadership behaviours. The third article builds on the traits activation theory (Tett & Burnett, 2003) to validate the combined effects of a manager’s personality and the context in which he or she operates to predict transformational leadership. The results ((nmanagers = 89; nsubordinates = 643) offer limited support to the rationale underlying the traits activation theory. Yet, it appears a manager’s relational traits (operationalized by the personality compound variable “supporting and cooperating”) are correlated to demonstrations of transformational leadership, when contextual factors (organizational consideration, decision latitude) are perceived positively by the manager. As a result, this research sheds some light on an element of variability put forth in previous studies regarding a manager’s relational inclinations by highlighting its sensitivity to positive contextual factors.

La dimension somatique du féminin est négative et mortifère et menaçant.Présentation de la population. L’échantillon est constitué de vingt femmes rencontrées dans le période d’ avril-octobre 2010 chez le service de gynécologie de l’Hôpital ARNAS Civico de Palerme. Outils. Entretiens et Test du Rorschach. Conclusions. A partir de l'analyse des protocoles Rorschach il est possible de repérer des points communs :- un défaut du processus associatif et de symbolisation témoignent d’une difficulté dans la gestion des affects.- Des angoisses somatiques.- Humeur instable.étude IIla discrepance du soi chez les femmes atteintes d’endometrioseObjectif. approfondir les aspects représentationnels concernant l’image du soi maternel et séductif chez les femmes atteintes d'endométriose et souligner les possibles effets de modération de la Discordance du Soi sur le lien entre endométriose et dépression. Hypothèse. L'endométriose n'est pas nécessairement cause d'une souffrance psychologique manifeste; la relation entre ces deux variables pourrait être modérée par des facteurs relatifs à une réorganisation de la représentation de l’identité propre.Outils. - ISDI "integrated Self-Discrepancy Index" Hardin et Lakin 2009 - Beck Depression Inventory (BDI) Beck et au.1961Conclusiones. L'endométriose induit la dépression chez les femmes qui, en même temps présentent un sentiment d'inadéquation concernant la représentation maternelle du Soi, elles se perçoivent comme des mères, réelles ou fantasmatiques, mauvaises et inadaptées. / Study IThe psychological functioning in women affected by endometriosisObjective. To investigate the articulations of the relationship between psyche-body, the mental functioning and to the psychological experience of women affected by endometriosis.Hypothesis. Women affected by endometriosis, would be have an inequality of the psychic functioning and they have difficulties in the management of the feelings and of the own physical representation. The somatic dimension of the feminine is negative and threatening.Participants. Participants are twenty women, met in period of April-October, 2010 at the gynaecology service of the ARNAS Hospital Civico of Palermo. Tools. Psychological consult; and Test of Rorschach. Resulted. From the analysis of Rorschach protocols it is possible to stress some common points:- defect of associative and symbolization process,- difficulty in the affectivity management.- somatic fears.- unstable mood.Study IIThe self discrepancy in women affected by endometriosisObjective. To investigate the self discrepancy concerning the maternal and seductive representation in women affected by endometriosis. To underline the possible effects of moderation of the self discrepancy on the link between endometriosis and depression. Hypothesis. The endometriosis is not a direct cause of a psychological suffering; the relation between these two variables could be moderated by personality factors.Tools. - ISDI "integrated Self-Discrepancy Index" Hardin et Lakin 2009 - Beck Depression Inventory (BDI) Beck et al.1961Conclusions. The endometriosis leads to the depression only in women who, at the same time present discrepancy of the self maternal representation, only if they perceive themselves as bad and inappropriate, real or imaginary, mothers.

Loneliness occurs in the absence of belonging or social connectedness and has been linked to many physical and mental health problems. Among these conditions are depression, anxiety, sleep disturbance, and stress. College students report these four conditions as the largest barriers to good academic performance. For as much is known about loneliness, much less is known about belonging and health or the role loneliness plays in these relationships prompting a need for investigation. Using a sample of 301 university students, we replicated previous findings that loneliness predicts depression, anxiety, sleep disturbance, and stress. Next we replicated and contributed new findings for the relationship between social connectedness and the same health outcomes of interest. Previous research has found gender to be a moderator in the relationship between loneliness and social connectedness. The current study found no evidence of moderation. Based upon the available literature, it was hypothesized that loneliness would mediate the relationship between social connectedness and the health outcomes of interest. Using conditional process modeling, loneliness was found to be a mediator in every case. These findings validate previous findings on the effects of loneliness on health. They also highlight the significance of social connectedness as a factor in health. Future research should investigate the effectiveness of social connectedness as focal point for treatment of mental and physical health conditions.

L’intérêt marqué et simultané de plusieurs champs de recherche pour le développement des fonctions exécutives (FE) a permis de mettre en lumière le rôle primordial de ces fonctions dans plusieurs sphères du développement de la petite enfance jusqu’à l’âge adulte. Les mécanismes développementaux associés aux différences individuelles restent par ailleurs encore peu étudiés. Les deux articles empiriques qui constituent la thèse visent à documenter le rôle des comportements maternels observés en bas âge dans la prédiction des FE mesurées à l’âge préscolaire. Les deux articles s’inscrivent dans la foulée des travaux qui, selon une approche écologique (Bronfenbrenner, 1979), considèrent les effets d’interaction entre différents facteurs explicatifs pour mieux comprendre les mécanismes impliqués dans le développement de l’enfant. En ce sens, le premier article examine les interactions possibles entre le statut socioéconomique (SSE) de la famille et différentes dimensions du concept de sensibilité maternelle, dans la prédiction de deux dimensions des FE, soit les FE-conflit et les FE-inhibition. Dans le cadre de cette étude, 114 dyades mères-enfants ont participé à trois visites à domicile. Le SSE a été mesuré par questionnaire dans le cadre d’une première visite dans la famille lorsque les enfants avaient six mois, la sensibilité maternelle a été évaluée à 12 mois à partir du Tri de cartes de comportements maternels (Pederson & Moran, 1995) et les FE à 36 mois à partir d’une batterie de tâches choisie sur la base des orientations proposées par Carlson (2005). Le deuxième article explore, en se basant sur postulats de la Théorie de la susceptibilité différentielle (TSD), les possibles interactions entre différentes dimensions du concept de sensibilité maternelle et le tempérament de l’enfant, et ce également dans la prédiction des FE. Pour ce faire, 72 dyades ont également participé à trois visites à domicile. La sensibilité maternelle a été évaluée à 12 mois à partir du Tri de cartes de comportements maternels (Pederson & Moran, 1995), le tempérament à 15 mois à l’aide d’un questionnaire rempli par la mère (ICQ; Bates, Freeland, & Lounsbury, 1979) et les FE à 36 mois à partir de la même batterie de tâche (Carlson, 2005). Les résultats du premier article révèlent des interactions significatives entre le statut socioéconomique et certaines dimensions de comportements maternels, de telle sorte que des comportements maternels de meilleure qualité sont prédicteurs d’une meilleure performance aux tâches de FE, mais seulement chez les enfants provenant de familles relativement désavantagées sur le plan socioéconomique et essentiellement en ce qui concerne les FE-inhibition. Quant aux résultats du deuxième article, ils confirment les hypothèses de la Théorie de la susceptibilité différentielle, en révélant que les enfants ayant un tempérament difficile sont plus affectés par des comportements maternels hostiles, de même que par l’absence de comportements positifs et bénéficient davantage de la présence de comportements positifs et de l’absence de comportements négatifs, et ceci également au regard des FE-inhibition. / The simultaneous and marked interest of many fields of research for the notion of executive functioning (EF) has allowed for the primordial role of these functions in many spheres of development to be identified. However, the developmental mechanisms associated with individual differences in EF are still under studied. The two empirical articles constituting this dissertation aim at documenting the role of maternal behaviors in the prediction of EF in the preschool period. Using an ecological approach (Bronfenbrenner, 1979), interaction effects between different explanatory factors are considered, with the goal of reaching a better understanding of the mechanisms underlying early EF development. To do so, the first article examines the interactions between family socioeconomic status (SES) and different dimensions of maternal behavior in the prediction of two specific components of EF, namely, conflict-EF and impulse control. 114 mother-child dyads participated in three home visits. SES was measured by a questionnaire filled by mothers during the first visit when their child was six months old and maternal behavior was observed in a second visit when the child was 12 months old, using the Maternal Behavior Q-Sort (MBQS; Pederson & Moran, 1995). Finally, child EF was assessed at 3 years with a battery of tasks chosen based on Carlson’s (2005) measurement guidelines. The second article explores, based on Differential Susceptibility Theory (DST), the interactions between different dimensions of maternal behavior and child temperament in the prediction of child EF. Seventy-two mother-child dyads participated in three home visits. Maternal sensitivity was observed when children were 12 months old, using the MBQS, child temperament was assessed at 15 months using a maternal report (ICQ; Bates, Freeland, & Lounsbury, 1979), and child EF was assessed with the same battery of tasks as in the first article. The results of the first article showed significant interactions between family SES and the quality of maternal behaviors in the prediction EF, such that maternal behavior was related to EF only for children in the lower end of the SES spectrum and those relations were found especially for impulse control. The results of the second article confirmed the hypothesis put forward by DST, revealing that children with difficult temperaments were more affected by hostile maternal behavior and the absence of positive behavior, and that these same children benefit more than their easier peers from the presence of positive behaviors, but only in the prediction of impulse control.

Social comparison influences well-being, especially during psychological threat. Social comparison outcomes have been theorized to depend on motivation, frequency, contrast versus identification, with a better- versus worse-off other. To reduce this complexity in the theory, 94 senior-housing residents were interviewed and cluster analysis was conducted. Four clusters emerged. Half the interviewees formed a cluster using only adaptive social comparison methods. Adaptives were contrasted with a cluster of indiscriminate comparers, a cluster striving for improvement, and a cluster of participants disagreeing with most questions. Clusters differed especially in patterns of downward identification, upward and downward contrast. Self-evaluation and uncertainty-reduction also differed between clusters; self-enhancement and self-improvement motivations did not. Cluster membership had no direct effect on well-being, but moderation analysis demonstrated threat-buffering of high neuroticism in the adaptive cluster. The benefits were not due to self-esteem or educational level. By separating individuals rather than behaviors, cluster analysis provides a fresh perspective.

The Syrian Muslim Brotherhood has since the start of the Syrian uprising in March 2011 moved from a low-key position in exile to become one of the main actors in the political opposition. There appears to be a consensus among researchers today on the democratic commitment of the Syrian Brotherhood. However, ambiguity remains regarding its commitment towards gender equality, women’s rights and participation. This essay focuses on the gender discourse of the Syrian Brotherhood’s leadership, according to its policy-documents, from 2004 – 2013. By applying a critical discourse analysis, a movement from a more Islamist, exclusionary discourse in 2004 towards a more inclusive, feminist inspired discourse in 2013 becomes apparent. Nonetheless, traditional gender roles linger and more Islamist and pan-Arab, pan-Islamic discourses are not distant features. The movement of the gender discourse towards greater inclusion confirms claims made by democratic theorists on inclusion and moderation.

In addition, evidence suggests that certain psychological characteristics of workers would vary positively or negatively influence the magnitude of the resources on the links with work and on well-being. Based on this evidence this study aimed to analyze the influence of organizational justice (distributive, procedures and interactional) and psychological capital on engagement at work and subjective well-being (emotional balance and life satisfaction). From the main goal, four hypotheses have been proposed: perception of organizational justice increases engagement at work (H1) and subjective well-being (H2); psychological capital was moderator of the relationship between organizational justice and subjective well-being (H3) and the relationship between organizational justice and engagement (H4), and that high levels of psychological capital would strengthen relations. The design was a cross-sectional quantitative, descriptive and non-probability sampling. From a sample of 293 workers with an average age of 38.3 (SD = 10.7) years, of which slightly more than half were women (56.3pc), coming from all regions of Brazil, predominantly in the Southeast (65.2pc) was measured with valid and accurate scales, through an online questionnaire, the organizational justice levels, psychological capital, engagement at work and subjective well-being. Two sets of multiple linear regression analysis to test the hypotheses were performed. In the first set of analyzes, the results of standard multiple linear regressions indicated that organizational justice influenced the levels of engagement at work and subjective well-being, and, in relation to engagement and emotional balance, only the interactional dimension of justice was significant predictor while distributive justice was the only significant predictor of life satisfaction. In the second set of analyzes, the hierarchical multiple linear regressions for each dimension of organizational justice, along with psychological capital and interaction term upon engagement at work and subjective well-being, they indicated that psychological capital moderated the relations of procedural justice and interactional justice on engagement at work. It was concluded from the results that the perception of being adequately remunerated for their efforts at work, participate in decisions that affect the work and be treated with respect and sincerity can influence the levels of pride and inspiration at work, engagement features, and may increase the subjective well-being levels, contributing to the prevailing experience of positive affect and positive satisfaction ratings with life. Moreover, although it is not possible to say that workers with higher levels of belief in their ability to perform their tasks and with good prospects for the future, can do without fair environments to engage in work, the results showed that these workers can suffer less influence of interactional and procedural justice to establish that bond with their work, demonstrating that these personal characteristics would act as shock absorbers given the lack of environmental resources. / Há indicativos de que recursos sociais do ambiente de trabalho, entre eles justiça organizacional, poderiam influenciar vínculos com o trabalho, além de impactarem os níveis de bem-estar dos trabalhadores. Além disso, evidências apontam que certas características psicológicas dos trabalhadores fariam variar positiva ou negativamente a magnitude da influência dos recursos sobre os vínculos com o trabalho e sobre bem-estar. Com base nessas evidências esse estudo teve como objetivo principal analisar a influência de justiça organizacional (distributiva, procedimentos e interacional) e capital psicológico sobre engajamento no trabalho e bem-estar subjetivo (balanço emocional e satisfação com a vida). A partir do objetivo principal, foram propostas quatro hipóteses: percepção de justiça organizacional aumenta o engajamento no trabalho (H1) e bem-estar subjetivo (H2); capital psicológico seria moderador da relação entre justiça organizacional e bem-estar subjetivo (H3) e da relação entre justiça organizacional e engajamento (H4), sendo que, níveis altos de capital psicológico fortaleceriam as relações. O delineamento utilizado foi de natureza quantitativa transversal, descritiva e com amostragem não probabilística. A partir de uma amostra composta por 293 trabalhadores com média de idade de 38,3 (DP=10,7) anos, dos quais um pouco mais da metade era composta por mulheres (56,3pc), oriundos de todas as regiões do Brasil, com predomínio da região Sudeste (65,2pc), mediu-se com escalas válidas e precisas, por meio de um questionário online, os níveis de justiça organizacional, capital psicológico, engajamento no trabalho e bem-estar subjetivo. Foram realizados dois conjuntos de análises de regressão linear múltipla para teste das hipóteses. No primeiro conjunto de análises, os resultados das regressões lineares múltiplas padrão indicaram que justiça organizacional influenciou os níveis de engajamento no trabalho e bem-estar subjetivo, sendo que, em relação a engajamento e balanço emocional, apenas a dimensão interacional da justiça foi preditora significativa, enquanto justiça distributiva foi a única preditora significativa de satisfação com a vida. No segundo conjunto de análises, as regressões lineares múltiplas hierárquicas de cada dimensão de justiça organizacional, juntamente com capital psicológico e termo de interação sobre engajamento no trabalho e sobre bem-estar subjetivo, indicaram que capital psicológico moderou as relações entre justiça de procedimentos e justiça interacional com engajamento no trabalho. Concluiu-se a partir dos resultados que a percepção de ser remunerado adequadamente pelos esforços no trabalho, participar das decisões que afetam o trabalho e ser tratado com respeito e sinceridade pode influenciar os níveis de orgulho e inspiração no trabalho, características de engajamento, além de poder aumentar os níveis de bem-estar subjetivo, contribuindo para a vivência predominante de afetos positivos e de avaliações positivas da satisfação com a vida. Além disso, apesar de não ser possível afirmar que trabalhadores com maiores níveis de crenças em sua capacidade para executar suas tarefas e com perspectivas positivas em relação ao futuro, possam prescindir de ambientes justos para se engajarem no trabalho, os resultados demonstraram que esses trabalhadores podem sofrer menos influência de justiça de procedimentos e interacional para estabelecerem esse vínculo com seu trabalho, demonstrando que essas características pessoais funcionariam como amortecedores diante da falta de recursos do ambiente.
