Este proyecto trata sobre la construcción de un modelo explicativo del Burnout y Engagement en trabajadores cordobeses. Se presentan como variables fundamentales al rol de las emociones y la autoeficacia profesional en este modelo. Se detallan primero los antecedentes del tema, los objetivos general y específicos, luego la metodología a implementar en una muestra de 300 trabajadores cordobeses. Se describen los procedimientos estadísticos a utilizar y las escalas psicométricas (Escala de Autoeficacia Profesional, AP-10, Escala PANAS, Escala de Burnout Maslach, Escala de Engagement (en las versiones adaptadas al medio local)

Background: Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS). Objective: To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Methods: Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged <65 years, hospitalized with diagnosis of ACS. The Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI), which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE), emotional distancing (EmD), dehumanization (De) and professional fulfillment (PF). The Lipp’s Stress Symptoms Inventory for Adults (LSSI) was applied to evaluate global stress. Results: Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. Conclusion: We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

Fragestellung: Diese Arbeit befasst sich mit der kritischen Auseinandersetzung mit demBurnout-Syndrom, sowie der Stellung dessen in der Öffentlichkeit und den Medien. Im diesemZusammenhang wird der Frage nach der Notwendigkeit dieser Diagnose nachgegangen.Methode: Während einer ausführlichen Literatur- Recherche, in der Stendaler Hochschulbibliotheksowie einer Online-Recherche, wurden viele aktuelle Beiträge zum Thema gesammelt.Auf dieser Grundlage erfolgte die theoretische und kritische Auseinandersetzung mitdem Burnout-Syndrom.Ergebnisse: Bei der Auseinandersetzung mit dem Thema Burnout fällt auf, dass in den letzten40 Jahren seit der „Entdeckung“ lediglich zusätzliche Informationen hinzugefügt werdenkonnten. Jedoch wurden keine validen Daten erhoben und so ist die wissenschaftliche Abgrenzungvon Burnout als eigenständiger Diagnose nicht erfolgt.Diskussion: Positive Effekte, die sich durch die Diagnose ergeben haben, sind Burnoutunspezifischund führen daher zu dem Schluss, dass Burnout als eigenständige klinischeDiagnose unbrauchbar ist.Schlüsselwörter: Burnout – Kritik – Depression - Medien

Préface My thesis consists of three essays where I consider equilibrium asset prices and investment strategies when the market is likely to experience crashes and possibly sharp windfalls. Although each part is written as an independent and self contained article, the papers share a common behavioral approach in representing investors preferences regarding to extremal returns. Investors utility is defined over their relative performance rather than over their final wealth position, a method first proposed by Markowitz (1952b) and by Kahneman and Tversky (1979), that I extend to incorporate preferences over extremal outcomes. With the failure of the traditional expected utility models in reproducing the observed stylized features of financial markets, the Prospect theory of Kahneman and Tversky (1979) offered the first significant alternative to the expected utility paradigm by considering that people focus on gains and losses rather than on final positions. Under this setting, Barberis, Huang, and Santos (2000) and McQueen and Vorkink (2004) were able to build a representative agent optimization model which solution reproduced some of the observed risk premium and excess volatility. The research in behavioral finance is relatively new and its potential still to explore. The three essays composing my thesis propose to use and extend this setting to study investors behavior and investment strategies in a market where crashes and sharp windfalls are likely to occur. In the first paper, the preferences of a representative agent, relative to time varying positive and negative extremal thresholds are modelled and estimated. A new utility function that conciliates between expected utility maximization and tail-related performance measures is proposed. The model estimation shows that the representative agent preferences reveals a significant level of crash aversion and lottery-pursuit. Assuming a single risky asset economy the proposed specification is able to reproduce some of the distributional features exhibited by financial return series. The second part proposes and illustrates a preference-based asset allocation model taking into account investors crash aversion. Using the skewed t distribution, optimal allocations are characterized as a resulting tradeoff between the distribution four moments. The specification highlights the preference for odd moments and the aversion for even moments. Qualitatively, optimal portfolios are analyzed in terms of firm characteristics and in a setting that reflects real-time asset allocation, a systematic over-performance is obtained compared to the aggregate stock market. Finally, in my third article, dynamic option-based investment strategies are derived and illustrated for investors presenting downside loss aversion. The problem is solved in closed form when the stock market exhibits stochastic volatility and jumps. The specification of downside loss averse utility functions allows corresponding terminal wealth profiles to be expressed as options on the stochastic discount factor contingent on the loss aversion level. Therefore dynamic strategies reduce to the replicating portfolio using exchange traded and well selected options, and the risky stock.

Background : In the present article, we propose an alternative method for dealing with negative affectivity (NA) biases in research, while investigating the association between a deleterious psychosocial environment at work and poor mental health. First, we investigated how strong NA must be to cause an observed correlation between the independent and dependent variables. Second, we subjectively assessed whether NA can have a large enough impact on a large enough number of subjects to invalidate the observed correlations between dependent and independent variables.Methods : We simulated 10,000 populations of 300 subjects each, using the marginal distribution of workers in an actual population that had answered the Siegrist's questionnaire on effort and reward imbalance (ERI) and the General Health Questionnaire (GHQ).Results : The results of the present study suggested that simulated NA has a minimal effect on the mean scores for effort and reward. However, the correlations between the effort and reward imbalance (ERI) ratio and the GHQ score might be important, even in simulated populations with a limited NA.Conclusions : When investigating the relationship between the ERI ratio and the GHQ score, we suggest the following rules for the interpretation of the results: correlations with an explained variance of 5% and below should be considered with caution; correlations with an explained variance between 5% and 10% may result from NA, although this effect does not seem likely; and correlations with an explained variance of 10% and above are not likely to be the result of NA biases.

Epuisement émotionnel, déshumanisation progressive de la relation avec l'autre et un sentiment d'échec professionnel. Le burnout est tout ça à la fois. La difficulté est de déceler à temps ces symptômes qui peuvent mettre parfois des mois, voire des années à se déclarer. Définition et tour d'horizon du burnout.
