Environnement dissuasif, risques et stratégies délinquantes

L‟utilité de la théorie de la dissuasion est régulièrement remise en question pour expliquer la relation entre les peines et la criminalité puisque les propriétés objectives de la peine ne semblent pas affecter les taux de criminalité, les perceptions que s‟en font les individus et la récidive des délinquants. Trois limites conceptuelles des auteurs qui remettent en question la dissuasion sont soulevées. Premièrement, les unités spatiales utilisées sont des territoires sur lesquels plusieurs corps policiers sont en fonction. Il y a donc peu de chances que tous les citoyens présents soient exposés au même message pénal. Deuxièmement, les chercheurs ont mesuré le risque objectif d‟être arrêté à l‟aide d‟un ratio entre le nombre d‟arrestations et le nombre de crimes rapportés. Cette conceptualisation est problématique puisque les résultats d‟autres études suggèrent que les citoyens ont peu de connaissances des propriétés objectives et qu‟il serait, ainsi, intéressant de se référer aux stimuli dissuasifs pour conceptualiser la notion de risques. Troisièmement, pour plusieurs chercheurs, la délinquance est considérée comme une activité pour laquelle les délits impunis découlent du hasard. Pourtant, les délinquants utilisent fréquemment des stratégies pour éviter les autorités policières. Ils sont donc proactifs dans leur impunité. De ces limites découlent quatre propositions : 1) afin de détecter les réels effets des propriétés de la peine sur la criminalité, les territoires utilisés dans les études doivent représenter des juridictions sur lesquelles un seul corps policier opère; 2) afin de détecter les réels effets des propriétés de la peine sur la criminalité, les études doivent être effectuées avec des données provenant d‟une juridiction dans laquelle les activités de répression sont augmentées significativement par rapport à leur seuil antérieur et maintenue sur une période de temps suffisamment longue; 3) les stimuli dissuasifs observés doivent être considérés comme des expériences vicariantes ; 4) l‟impunité doit être définie comme étant une expérience recherchée par les délinquants. Deux études ont été réalisées dans le cadre de cette thèse. D‟abord, une étude a été réalisée à l‟aide de données issues des rapports policiers de collisions et des constats d‟infraction rendus. Les résultats montrent que l‟augmentation de la répression policière ii sur le territoire du Service de Police de la Ville de Montréal a fait diminuer le nombre de collisions. Au même moment, les collisions sont demeurées stables sur le territoire desservis par le Service de police de la Ville de Québec. Dans un deuxième temps, une étude perceptuelle a été réalisée avec un échantillon d‟étudiants universitaires. Les résultats démontrent des effets mitigés des stimuli dissuasifs sur les perceptions que se font les individus de leurs risques d‟être arrêté et sur leurs comportements délinquants. Chez les moins délinquants, les stimuli dissuasifs font augmenter la perception que les délinquants se font de leurs risques. Par contre, les plus motivés à commettre des délits de la route développent des stratégies en réaction aux opérations policières plutôt que d‟en craindre les représailles. Ces tactiques d‟évitement n‟assurent pas une impunité totale, ni une perception moins élevée des risques de recevoir une contravention, mais elles retardent le moment où le délinquant sera confronté à la punition.

Territorialización de la inseguridad ciudadana en Bogotá: La Calle del Bronx

La tesis devela la connotación sistemática y multicausal de lo que a través de la investigación se denomina como "Procesos de Territorialización de la Inseguridad Ciudadana". Mediante un estudio de caso, se pone en evidencia la apropiación y captura sostenida en el tiempo de fenómenos como la inseguridad y la criminalidad, sobre determinadas zonas o barrios urbanos que por sus características socioeconómicas, políticas, geográficas, culturales, laborales y de mercado de quienes los habitan o frecuentan, se consideran como sectores "críticos y/o vulnerables".

Fatores que influenciam a predisposição dos usuários em aderir a uma política de segurança da informação

The information constitutes one of the most valuable strategic assets for the organization. However, the organizational environment in which it is inserted is very complex and heterogeneous, making emerging issues relevant to the Governance of information technology (IT) and Information Security. Academic Studies and market surveys indicate that the origin of most accidents with the information assets is the behavior of people organization itself rather than external attacks. Taking as a basis the promotion of a culture of safety among users and ensuring the protection of information in their properties of confidentiality, integrity and availability, organizations must establish its Information Security Policy (PSI). This policy is to formalise the guidelines in relation to the security of corporate information resources, in order to avoid that the asset vulnerabilities are exploited by threats and can bring negative consequences to the business. But, for the PSI being effective, it is required that the user have readiness to accept and follow the procedures and safety standards. In the light of this context, the present study aims to investigate what are the motivators extrinsic and intrinsic that affect the willingness of the user to be in accordance with the organization's security policies. The theoretical framework addresses issues related to IT Governance, Information Security, Theory of deterrence, Motivation and Behavior Pro-social. It was created a theoretical model based on the studies of Herath and Rao (2009) and D'Arcy, Hovav and Galletta (2009) that are based on General Deterrence Theory and propose the following influencing factors in compliance with the Policy: Severity of Punishment, Certainty of Detection, Peer Behaviour, Normative Beliefs, Perceived Effectiveness and Moral Commitment. The research used a quantitative approach, descriptive. The data were collected through a questionnaire with 18 variables with a Likert scale of five points representing the influencing factors proposed by the theory. The sample was composed of 391 students entering the courses from the Center for Applied Social Sciences of the Universidade Federal do Rio Grande do Norte. For the data analysis, were adopted the techniques of Exploratory Factor Analysis, Analysis of Cluster hierarchical and nonhierarchical, Logistic Regression and Multiple Linear Regression. As main results, it is noteworthy that the factor severity of punishment is what contributes the most to the theoretical model and also influences the division of the sample between users more predisposed and less prone. As practical implication, the research model applied allows organizations to provide users less prone and, with them, to carry out actions of awareness and training directed and write Security Policies more effective.

Deterrence and Incapacitation: Towards a Unified Theory of Criminal Punishment

Economic models of crime have focused primarily on the goal of deterrence; the goal of incapacitation has received much less attention. This paper adapts the standard deterrence model to incorporate incapacitation. When prison only is used, incapacitation can result in a longer or a shorter optimal prison term compared to the deterrence-only model. It is longer if there is underdeterrence, and shorter if there is overdeterrence. In contrast, when a fine is available and it is not constrained by the offender's wealth, the optimal prison term is zero. Since the fine achieves first-best deterrence, only efficient crimes are committed and hence, there is no gain from incapacitation.

A theory of optimal random crackdowns

An incentives based theory of policing is developed which can explain the phenomenon of random “crackdowns,” i.e., intermittent periods of high interdiction/surveillance. For a variety of police objective functions, random crackdowns can be part of the optimal monitoring strategy. We demonstrate support for implications of the crackdown theory using traffic data gathered by the Belgian Police Department and use the model to estimate the deterrence effectof additional resources spent on speeding interdiction.

A Simple Theory of Increasing Penalties for Repeat Offenders

A feature of many penal codes is that punishments are more severe for repeat offenders, yet economic models have had a hard time providing a theoretical justification for this practice. This paper offers an explanation based on the wage penalty suffered by individuals convicted of crime. While this penalty probably deters some first-timers from committing crimes, it actually hampers deterrence of repeat offenders because of their diminished employments opportunities. We show that in this setting, an escalating penalty scheme is optimal and time consistent.

[the Teaching Of Social Sciences In Health: Between Practice And Theory].

The models of teaching social sciences and clinical practice are insufficient for the needs of practical-reflective teaching of social sciences applied to health. The scope of this article is to reflect on the challenges and perspectives of social science education for health professionals. In the 1950s the important movement bringing together social sciences and the field of health began, however weak credentials still prevail. This is due to the low professional status of social scientists in health and the ill-defined position of the social sciences professionals in the health field. It is also due to the scant importance attributed by students to the social sciences, the small number of professionals and the colonization of the social sciences by the biomedical culture in the health field. Thus, the professionals of social sciences applied to health are also faced with the need to build an identity, even after six decades of their presence in the field of health. This is because their ambivalent status has established them as a partial, incomplete and virtual presence, requiring a complex survival strategy in the nebulous area between social sciences and health.

Atomic Charge Transfer-counter Polarization Effects Determine Infrared Ch Intensities Of Hydrocarbons: A Quantum Theory Of Atoms In Molecules Model.

Atomic charge transfer-counter polarization effects determine most of the infrared fundamental CH intensities of simple hydrocarbons, methane, ethylene, ethane, propyne, cyclopropane and allene. The quantum theory of atoms in molecules/charge-charge flux-dipole flux model predicted the values of 30 CH intensities ranging from 0 to 123 km mol(-1) with a root mean square (rms) error of only 4.2 km mol(-1) without including a specific equilibrium atomic charge term. Sums of the contributions from terms involving charge flux and/or dipole flux averaged 20.3 km mol(-1), about ten times larger than the average charge contribution of 2.0 km mol(-1). The only notable exceptions are the CH stretching and bending intensities of acetylene and two of the propyne vibrations for hydrogens bound to sp hybridized carbon atoms. Calculations were carried out at four quantum levels, MP2/6-311++G(3d,3p), MP2/cc-pVTZ, QCISD/6-311++G(3d,3p) and QCISD/cc-pVTZ. The results calculated at the QCISD level are the most accurate among the four with root mean square errors of 4.7 and 5.0 km mol(-1) for the 6-311++G(3d,3p) and cc-pVTZ basis sets. These values are close to the estimated aggregate experimental error of the hydrocarbon intensities, 4.0 km mol(-1). The atomic charge transfer-counter polarization effect is much larger than the charge effect for the results of all four quantum levels. Charge transfer-counter polarization effects are expected to also be important in vibrations of more polar molecules for which equilibrium charge contributions can be large.

Beliefs Related To Adherence To Oral Antidiabetic Treatment According To The Theory Of Planned Behavior.

to identify salient behavioral, normative, control and self-efficacy beliefs related to the behavior of adherence to oral antidiabetic agents, using the Theory of Planned Behavior. cross-sectional, exploratory study with 17 diabetic patients in chronic use of oral antidiabetic medication and in outpatient follow-up. Individual interviews were recorded, transcribed and content-analyzed using pre-established categories. behavioral beliefs concerning advantages and disadvantages of adhering to medication emerged, such as the possibility of avoiding complications from diabetes, preventing or delaying the use of insulin, and a perception of side effects. The children of patients and physicians are seen as important social references who influence medication adherence. The factors that facilitate adherence include access to free-of-cost medication and taking medications associated with temporal markers. On the other hand, a complex therapeutic regimen was considered a factor that hinders adherence. Understanding how to use medication and forgetfulness impact the perception of patients regarding their ability to adhere to oral antidiabetic agents. medication adherence is a complex behavior permeated by behavioral, normative, control and self-efficacy beliefs that should be taken into account when assessing determinants of behavior.

Pulsar binary systems in a nonsymmetric theory of gravitation II. Dipole radiation

This paper deals with the emission of gravitational radiation in the context of a previously studied metric nonsymmetric theory of gravitation. The part coming from the symmetric part of the metric coincides with the mass quadrupole moment result of general relativity. The one associated to the antisymmetric part of the metric involves the dipole moment of the fermionic charge of the system. The results are applied to binary star systems and the decrease of the period of the elliptical motion is calculated.

Nonexistence of regular stationary solution in a metric nonsymmetric theory of gravitation

It is proven that the field equations of a previously studied metric nonsymmetric theory of gravitation do not admit any non-singular stationary solution which represents a field of non-vanishing total mass and non-vanishing total fermionic charge.
