L'influence de la culture organisationnelle sur l'épuisement professionnel ; étude comparative entre cols blancs et policiers d'un service de police urbain.

Ce mémoire élaboré dans le cadre d'une étude plus vaste sur la santé mentale au travail étudie l'effet de la culture organisationnelle ainsi que certains facteurs du travail comme la supervision abusive, la latitude décisionnelle, l'utilisation des compétences, l'autorité décisionnelle, les demandes psychologiques, le soutien social ainsi que l'horaire de travail sur l'épuisement professionnel et ses trois dimensions. Ces facteurs, à l'exception de la culture organisationnelle ont fait l'objet d'études approfondies dans le passé. Ce mémoire se base sur un modèle connu et régulièrement utilisé mesurant l'effet de ces facteurs du travail sur la santé mentale. Ce modèle est communément appelé le modèle demandes-contrôle de Karasek. L'échantillon à l'étude est constitué de 384 policiers et travailleurs cols blancs travaillant pour le service de police de la Ville de Montréal. La récolte des données à été effectuée en 2008 et 2009. Ce mémoire confirme en partie les résultats fréquemment observés dans les études sur le sujet. La supervision abusive, les demandes psychologiques et certains types de culture augmentent le niveau d'épuisement professionnel. D'autres variables comme la latitude décisionnelle et certains autres types de culture organisationnelle réduisent le niveau d'épuisement professionnel.

Les pratiques de la police de proximité dans le Canton de Vaud (Suisse) avant la Loi sur la Police Vaudoise du 1er Janvier 2012

En Grande-Bretagne et en Amérique du Nord, la police est une institution publique qui suscite de nombreux travaux académiques. En France, elle est perçue comme un objet sale jusqu’aux travaux de Montjardet. En Suisse, la police est le reflet de la structure fédérale du pays. A travers un cadre réglementaire et légal, chaque canton a organisé sa police. Ainsi, le canton de Vaud s’est doté d’une police cantonale et de polices municipales dont le fonctionnement se fonde sur la proximité. Seules la police cantonale et celle de Lausanne disposent d’une compétence maximale. Bien que la police de proximité soit bien documentée au niveau légal, il n’existe pas de recherche compréhensive sur le fonctionnement de cet ensemble de principes policiers. Ce manque de connaissance pratique est problématique car le canton a entrepris une réforme policière qui est entrée en vigueur au 1er Janvier 2012. Dans ses pratiques liées à l’information, la police de proximité semble s’inspirer de deux modèles incompatibles que sont la police de communauté et l’intelligence led policing. C’est pourquoi, dans cette recherche, nous souhaitons comprendre comment les modèles théoriques trouvent à s’appliquer dans la pratique de la police de proximité. Nous avons opté pour une démarche qualitative semi-dirigée en réalisant 23 entretiens avec des policiers vaudois. L’analyse thématique a été réalisée à l’aide du logiciel Atlas Ti. Trois résultats ont retenu notre attention. Tout d’abord, notre analyse a permis de clarifier la notion de proximité par rapport à celle de communauté tout en tenant compte des particularismes locaux de redevabilité. Ensuite, nous avons identifié les divers circuits de l’information et mis en évidence les divergences dans le vocabulaire lié à l’analyse criminelle. Enfin, il apparaît que la police vaudoise se positionne comme une interface qui coordonne les partenaires susceptibles de résoudre les problèmes de la population.

Lower Cortisol Activity is Associated with First-Time Driving while Impaired

Driving while impaired (DWI) is a grave and persistent high-risk behavior. Previous work demonstrated that DWI recidivists had attenuated cortisol reactivity compared to non-DWI drivers. This suggests that cortisol is a neurobiological marker of high-risk driving. The present study tested the hypothesis that this initial finding would extend to first-time DWI (fDWI) offenders compared to non-DWI drivers. Male fDWI offenders (n = 139) and non-DWI drivers (n = 31) were exposed to a stress task, and their salivary cortisol activity (total output and reactivity) was measured. Participants also completed questionnaires on sensation seeking, impulsivity, substance use, and engagement in risky and criminal behaviors. As hypothesized, fDWI offenders, compared to non-DWI drivers, had lower cortisol reactivity; fDWI offenders also showed lower total output. In addition, cortisol activity was the most important predictor of group membership, after accounting for alcohol misuse patterns and consequences and other personality and problem behavior characteristics. The findings indicate that attenuated cortisol activity is an independent factor associated with DWI offending risk at an earlier stage in the DWI trajectory than previously detected.

Human Rights Violations in Police Custody

Human rights are the basic rights of every individual against the state or any other public authority as a member of the human family irrespective of any other consideration. Thus every individual of the society has the inherent right to be treated with dignity in all situations including arrest and keeping in custody by the police. Rights of an individual in police custody are protected basically by the Indian Constitution and by various other laws like Code of Criminal Procedure, Evidence Act, Indian Penal Code and Protection of Human Rights Act. The term `custody' is defined neither in procedural nor in substantive laws. The word custody means protective care. The expression `police custody' as used in sec. 27 of Evidence Act does not necessarily mean formal arrest. In India with special reference to Kerala and evolution and development of the concept of human rights and various kinds of human rights violations in police custody in different stages of history. Human rights activists and various voluntary organisations reveals that there are so many factors contributing towards the causes of violations of human rights by police. Sociological causes like ambivalent outlook of the society with respect to the use of third degree methods by the police, economic causes like meager salary and inadequate living conditions, rampant corruption in police service, unnecessary political interference in the crime investigation, work load of police personnel without any time limit and periodic holidays, unnecessary pressure from superior police officers and the general public for speedy detection causing great mental strain to the investigating officers, defective system of recruitment and training, imperfect system of investigation and lack of public co-operation are some of the factors identified in the field survey towards the causes of violations of human rights in police custody.

Influence of the driving mechanism on the response of systems with athermal dynamics: The example of the random-field Ising model

We investigate the influence of the driving mechanism on the hysteretic response of systems with athermal dynamics. In the framework of local mean-field theory at finite temperature (but neglecting thermally activated processes), we compare the rate-independent hysteresis loops obtained in the random field Ising model when controlling either the external magnetic field H or the extensive magnetization M. Two distinct behaviors are observed, depending on disorder strength. At large disorder, the H-driven and M-driven protocols yield identical hysteresis loops in the thermodynamic limit. At low disorder, when the H-driven magnetization curve is discontinuous (due to the presence of a macroscopic avalanche), the M-driven loop is reentrant while the induced field exhibits strong intermittent fluctuations and is only weakly self-averaging. The relevance of these results to the experimental observations in ferromagnetic materials, shape memory alloys, and other disordered systems is discussed.

‘Driving Forces of Investment Decisions in Mutual Funds’

Unfortunately, in India it is a fact that most of the investors are not interested in mutual funds. Those who are investing, they are investing only very small amounts. But what is important to be noted here is that when compared to other financial instruments, investments in mutual funds are safer and also yields more returns on the investment portfolio. Moreover as an investment avenue mutual fund is available for those investors who are not willing to take any exposure directly in the security market. It also helps such investors to build their wealth over a period of time. At the retail level, investors are unique and are highly heterogeneous, and the mutual fund schemes' selection will also differ depends on their expectations. Hence, investors’ expectation is a very important factor in this regard that needs to be analysed by all the investment houses. Hence, the factors that drive the investment decisions of individual investors to meet their expectations by investing money in mutual funds need an in-depth analysis. These driving forces include the preference of investors on mutual fund compared to various available avenues of financial investments, risk attitude of investors, influence of characteristics of instruments of mutual funds on investors, the investment specific attitudes of investors, and influence of qualities of fund management on investors. The success of any mutual fund, a popular means of investment, depends on how effectively an Asset Management Company has been able to understand the level of influence of these factors on the decision of investors to invest in mutual funds. For a substantial growth in the mutual fund market, there must be a high level precision in the design and marketing of the products of mutual funds taking into account these driving forces by the Asset Management Companies. Therefore, there is a need to conduct a detailed study on investments in mutual funds in this direction. A review of available literature also revealed that no detailed study on mutual funds has so far been attempted in this direction; hence the present study on Driving Forces of Investment Decisions in Mutual Funds is undertaken.

Reinforcement Learning solution for Unit Commitment Problem through pursuit method

Unit commitment is an optimization task in electric power generation control sector. It involves scheduling the ON/OFF status of the generating units to meet the load demand with minimum generation cost satisfying the different constraints existing in the system. Numerical solutions developed are limited for small systems and heuristic methodologies find difficulty in handling stochastic cost functions associated with practical systems. This paper models Unit Commitment as a multi stage decision task and Reinforcement Learning solution is formulated through one efficient exploration strategy: Pursuit method. The correctness and efficiency of the developed solutions are verified for standard test systems

The Pursuit of Alternatives

Stories of peoples’ struggles across the globe are testaments to their determination to resist exploitation and injustice, and to imagine and construct their own narratives of economic and political difference. These stories of emancipatory moments demonstrate that something radically different in terms of dominant socio-economic relations and mental conceptions of the world may arise out of and beyond capitalism. The Pursuit of Alternatives: Stories of Peoples’ Economic and Political Struggles Around the World presents a fresh and new perspective on how the ‘process of becoming’ alternatives might take place based on peoples’ lived experiences. The chapters here, by labour activists and academics, explore how various forms of peoples’ economic and political initiatives and struggles in six countries – Brazil, Canada, Colombia, Nigeria, the Philippines, and South Korea – might become ‘actually existing’ spaces and moments for the development of critical consciousness and transformative capacities which are both central in challenging the dominant social, economic and political relations. The stories in this book bring to light today’s language of peoples’ struggles; what inspires people to create their own emancipatory moments and spaces for transformative self-change. While this book does not aim to propose an alternative to capitalism per se, it makes a stimulating contribution to the continuing debate on what alternatives to capitalist relations and arrangements might look like by grounding these alternatives in the everyday lives and struggles of workers, women, aboriginal peoples, the unemployed, and the poor.

The Pursuit of Acquisition Intrapreneurs

This report represents research conducted at the Massachusetts Institute of Technology under the Lean Aerospace Initiative (LAI) program. The research focused on identifying Acquisition Intrapreneurs, viewed and defined for the purpose of this research as, individuals within the acquisition profession who take direct responsibility for turning ideas into products through assertive risk taking. The basis for this research stems from the agile acquisition push for “breeding innovators” to achieve a leaner and more responsive approach to the design, build, test and fielding of warfighting systems.

Les expériences françaises de police de proximité

El artículo explora las experiencias francesas del modelo de policía de proximidad. Con base en la división policial francesa entre la gendarmería de corte militar y la policía nacional, institucional civil. El autor da cuenta de las experiencias de vieja data y el desarrollo que ha tenido la policía de proximidad en Francia. Aunque el modelo fue adoptado de manera reciente en ese país (desde finales de los años 90), la policía francesa ha tenido siempre una vocación de cercanía con los vecinos y los ciudadanos en general. Sin embargo, recientemente las experiencias de policía de proximidad han cedido ante las tareas y políticas de represión impuestas para combatir la delincuencia creciente. Sólo las policías municipales, enteramente dependientes de los alcaldes y tradicionalmente cuestionadas, han suplido tangencialmente este rol de policía cercana a la comunidad. El modelo de policía de proximidad en Francia no ha sido suficientemente evaluado y se encuentra en medio del debate sobre su eficacia real.-----This article examines the French experience with the so called ‘police de proximite’ or ‘proximity police’. Based on the French division of the police force into the gendarmerie, of military nature, and the national police, a civil institution, the autor describes in detail the experiences and developments of the longstanding ‘police de proximite’ in France. Even if the model was established as recently as the late 90’s, the French police force has tended right from its beginnings to be close to neighbours and citizens in general, an experience that has yielded lately to repressive tasks and policies to combat a raising crime rate. Only the local boroughs’police, entirely dependent on the city mayors and traditionally called into question, has marginally played this role of communityclase policing. In short, the proximity policing model has not been sufficiently assessed and its efficiency is now in the middle of intense debate.

Aplicación del cuestionario nórdico para el análisis de síntomas musculoesqueleticos en trabajadores del Cuerpo Técnico de Policia Judicial: investigacion (CTI)

RESUMEN INTRODUCCION Los desórdenes musculoesqueléticos constituyen uno de los más comunes y costosos problemas de salud en el trabajo en todo el mundo. La detección a tiempo de síntomas iniciales debe ser una prioridad de los sistemas de vigilancia epidemiológica. El objetivo de este trabajo de investigación fue determinar la prevalencia de los desórdenes musculoesqueléticos (DME) en la población de funcionarios del cuerpo de policía judicial de Bogotá en el año 2014. MATERIALES Y METODOS Estudio de corte transversal con una muestra de 300 trabajadores a los que se les aplico el cuestionario Nórdico de Síntomas musculoesqueléticos. RESULTADOS Se encuesto al 33,9% de los trabajadores pertenecientes al cuerpo técnico de Policía Judicial de la Fiscalía General de la Nación en la ciudad de Bogotá. Los trabajadores evaluados tienen una edad promedio de 41,9 años, con un predominio del género femenino (54%), encontrándose que la mayoría de los que respondieron al cuestionario 87,66% (n=263) habían presentado algún síntoma musculoesqueléticos en los últimos 12 meses. Un hallazgo significativo fue la afectación cervical en el 53% (n=159) de los que reportaron sintomatología musculo esquelética. CONCLUSIONES La población perteneciente a la Policía Técnica Judicial en la ciudad de Bogotá presenta una alta prevalencia (87,66%) de síntomas que afectan al sistema musculoesquelético, principalmente comprometiendo las regiones de columna cervical, parte baja de la espalda y parte alta de la espalda, con una mayor afectación a las personas de género femenino.
