Conspiracy theories can be treated as both rational narratives of the world as well as outcomes of underlying maladaptive traits. Here, we examined associations between belief in conspiracy theories and individual differences in personality disorders. An Internet-based sample (N=259) completed measures of belief in conspiracy theories and the 25 facets of the Personality Inventory for DSM-5 (PID-5). Preliminary analyses showed no significant differences in belief in conspiracy theories across participant sex, ethnicity, and education. Regression analyses showed that the PID-5 facets of Unusual Beliefs and Experiences and, to a lesser extent, Suspiciousness, significantly predicted belief in conspiracy theories. These findings highlight a role for maladaptive personality traits in understanding belief in conspiracy theories, but require further investigation.

This article introduces the Dyadic Coping Inventory (DCI; Bodenmann, 2008) and aims (1) to investigate the reliability and aspects of the validity of the Italian and French versions of the DCI, and (2) to replicate its factor structure and reliabilities using a new Swiss German sample. Based on 216 German-, 378 Italian-, and 198 French-speaking participants, the factor structure of the original German inventory was able to be replicated by using principal components analysis in all three groups after excluding two items in the Italian and French versions. The latter were shown to be as reliable as the German version with the exception of the low reliabilities of negative dyadic coping in the French group. Confirmatory factor analyses provided additional support for delegated dyadic coping and evaluation of dyadic coping. Intercorrelations among scales were similar across all three languages groups with a few exceptions. Previous findings could be replicated in all three groups, showing that aspects of dyadic coping were more strongly related to marital quality than to dyadic communication. The use of the dyadic coping scales in the actor-partner interdependence model, the common fate model, and the mutual influence model is discussed.

Syndrome de stress scolaire chronique, le bumout de l'élève ou bumout scolaire suscite un intérêt grandissant mais ses déterminants sont encore peu connus. De plus, ce phénomène est rarement étudié chez les adolescents francophones et aucune recherche n'a encore été menée en Suisse. Par conséquent, au travers de ce travail de thèse, nous proposons d'étendre la recherche sur le bumout scolaire aux adolescents de Suisse francophone et d'apporter des précisions sur ses facteurs de risque ou de protection. Pour ce faire, nous avons mené deux recherches empiriques impliquant 861 adolescents âgés de 14 à 18 ans et scolarisés en Suisse francophone. Ces adolescents ont répondu à une série d'échelles évaluant notamment le burnout scolaire, le stress scolaire, le soutien social, la consommation de substances et le parcours scolaire. Les résultats montrent tout d'abord que l'inventaire de Burnout Scolaire, version française du School Burnout lnventory, est un outil fiable et valide. Ensuite, il apparaît que le burnout scolaire touche jusqu'à 24% des adolescents de Suisse francophone et que ce dernier se caractérise par une perte d'intérêt pour l'école, une grande remise en question du sens du travail scolaire ainsi qu'un sentiment élevé d'insuffisance à l'école. Il apparaît également que le stress scolaire lié au succès et à l'avenir scolaire augmente le risque de bumout alors que le soutien des parents et des enseignants le diminue. Par ailleurs, nous mettons en évidence que l'effet du soutien social sur le burnout scolaire est médiatisé par le stress scolaire, ce qui souligne d'autant plus le rôle protecteur du soutien social. Nos résultats montrent également que les niveaux de bumout scolaire varient en fonction, d'une part de certaines caractéristiques du contexte scolaire et d'autre part en fonction de la sévérité de la consommation de substances des adolescents. Enfin, les connaissances accumulées dans ce travail et leur mise en perspective dans un modèle d'intervention précoce permettent d'insister sur le rôle de l'école et des professionnels de l'école dans la prévention du burnout scolaire. -- Syndrome of chronic school stress, pupil 's bumout or school bumout is of growing interest. However, little is known about its determinants. Moreover, this phenomenon is rarely studied in French speaking adolescents and no research has yet been conducted in Switzerland. Therefore, through this thesis, we propose to extend the research on school bumout to Swiss French speaking adolescents and to clarify its risk and protective factors. To achieve this, we conducted two empirical research involving 861 adolescents aged 14 to 18 and enrolled in the French part of Switzerland. These adolescents were asked to answer a questionnaire about school bumout, academic stress, social support, substance use and schooling. Results first show, that the French version of the School Bumout Inventory is a reliable and valid tool. lt then appears that school bumout affects up to 24% of adolescents in the French speaking part of Switzerland and that this phenomenon is characterized by a loss of interest in school, a great challenge to the sense of school work and a high sense of insufissance school. lt also appears that stress related to school success and academic future increases the risk of bumout while parents and teachers support decreases it. Moreover, we highlight that the effect of social support on school bumout is mediated by school stress, which further underscores the protective role of social support. Our results also show that school bumout levels vary depending on characteristics of the school context and on the severity of substance use of adolecents. Finally, the knowledge accumulated in this work and putting it onto perspective within early intervention model enable to insist on the role of school and school professionals in the prevention of school bumout

Adaptive systems of governance are increasingly gaining attention in respect to complex and uncertain social-ecological systems. Adaptive co-management is one strategy to make adaptive governance operational and holds promise with respect to community climate change adaptation as it facilitates participation and learning across scales and fosters adaptive capacity and resilience. Developing tools which hasten the realization of such approaches are growing in importance. This paper describes explores the Social Ecological Inventory (SEI) as a tool to 'prime' a regional climate change adaptation network. The SEI tool draws upon the social-ecological systems approach in which social and ecological systems are considered linked. SEIs bridge the gap between conventional stakeholder analysis and biological inventories and take place through a six phase process. A case study describes the results of applying an SEI to prime an adaptive governance network for climate change adaptation in the Niagara Region of Canada. Lessons learned from the case study are discussed and highlight how the SEI catalyzed the adaptive co-management process in the case. Future avenues for SEIs in relation to climate change adaptation emerge from this exploratory work and offer opportunities to inform research and adaptation planning.

In this thesis T-policy is implemented to the inventory system with random lead time and also repair in the reliability of k-out-of-n system. Inventory system may be considered as the system of keeping records of the amounts of commodities in stock. Reliability is defined as the ability of an entity to perform a required function under given conditions for a given time interval. It is measured by the probability that an entity E can perform a required function under given conditions for the time interval. In this thesis considered k-out-of-n system with repair and two modes of service under T-policy. In this case first server is available always and second server is activated on elapse of T time units. The lead time is exponentially distributed with parameter and T is exponentially distributed with parameter from the epoch at which it was inactivated after completion of repair of all failed units in the previous cycle, or the moment n-k failed units accumulate. The repaired units are assumed to be as good as new. In this study , three different situations, ie; cold system, warm system and hot system. A k-out-of-n system is called cold, warm or hot according as the functional units do not fail, fail at a lower rate or fail at the same rate when system is shown as that when it is up.

The thesis deals with analysis of some Stochastic Inventory Models with Pooling/Retrial of Customers.. In the first model we analyze an (s,S) production Inventory system with retrial of customers. Arrival of customers from outside the system form a Poisson process. The inter production times are exponentially distributed with parameter µ. When inventory level reaches zero further arriving demands are sent to the orbit which has capacity M(<∞). Customers, who find the orbit full and inventory level at zero are lost to the system. Demands arising from the orbital customers are exponentially distributed with parameter γ. In the model-II we extend these results to perishable inventory system assuming that the life-time of each item follows exponential with parameter θ. The study deals with an (s,S) production inventory with service times and retrial of unsatisfied customers. Primary demands occur according to a Markovian Arrival Process(MAP). Consider an (s,S)-retrial inventory with service time in which primary demands occur according to a Batch Markovian Arrival Process (BMAP). The inventory is controlled by the (s,S) policy and (s,S) inventory system with service time. Primary demands occur according to Poissson process with parameter λ. The study concentrates two models. In the first model we analyze an (s,S) Inventory system with postponed demands where arrivals of demands form a Poisson process. In the second model, we extend our results to perishable inventory system assuming that the life-time of each item follows exponential distribution with parameter θ. Also it is assumed that when inventory level is zero the arriving demands choose to enter the pool with probability β and with complementary probability (1- β) it is lost for ever. Finally it analyze an (s,S) production inventory system with switching time. A lot of work is reported under the assumption that the switching time is negligible but this is not the case for several real life situation.

This thesis is devoted to the study of some stochastic models in inventories. An inventory system is a facility at which items of materials are stocked. In order to promote smooth and efficient running of business, and to provide adequate service to the customers, an inventory materials is essential for any enterprise. When uncertainty is present, inventories are used as a protection against risk of stock out. It is advantageous to procure the item before it is needed at a lower marginal cost. Again, by bulk purchasing, the advantage of price discounts can be availed. All these contribute to the formation of inventory. Maintaining inventories is a major expenditure for any organization. For each inventory, the fundamental question is how much new stock should be ordered and when should the orders are replaced. In the present study, considered several models for single and two commodity stochastic inventory problems. The thesis discusses two models. In the first model, examined the case in which the time elapsed between two consecutive demand points are independent and identically distributed with common distribution function F(.) with mean (assumed finite) and in which demand magnitude depends only on the time elapsed since the previous demand epoch. The time between disasters has an exponential distribution with parameter . In Model II, the inter arrival time of disasters have general distribution (F.) with mean ( ) and the quantity destructed depends on the time elapsed between disasters. Demands form compound poison processes with inter arrival times of demands having mean 1/. It deals with linearly correlated bulk demand two
Commodity inventory problem, where each arrival demands a random number of items of each commodity C1 and C2, the maximum quantity demanded being a (< S1) and b(
