Le contrôle précis des boucles de régulation existantes sur une machine frigorifique est essentiel à son bon fonctionnement. Il existe plusieurs méthodes de régulation parmi lesquelles on retrouve la plus ancienne et la plus connue : la commande PID (Proportionnelle, Intégrale et Dérivée). Malgré la simplicité apparente des relations mises en jeu, le régulateur PID est assez délicat à ajuster sur des processus présentant de fortes perturbations comme les installations frigorifiques. L’objectif du travail présenté est de mettre en œuvre une commande prédictive fonctionnelle (PFC) afin de réguler la surchauffe en sortie d’évaporateur, la pression de condensation et la puissance frigorifique sur une installation munie d’un compresseur à vitesse variable. L’utilisation d’une commande PFC nécessite de réaliser une prédiction de l’évolution à venir de la sortie du procédé. C’est un modèle interne qui fait office de modèle de connaissance. En assimilant le procédé à un système du premier ordre, la mise en œuvre de cette commande ne nécessite que trois paramètres : un gain statique, une constante de temps et un retard pur. L’originalité de la démarche développée a consisté à réaliser une modélisation physique de la machine afin de déterminer les paramètres précédents par une approche macroscopique. Une bibliothèque de modèles physiques a été élaborée permettant de simuler le comportement de différents évaporateurs, condenseurs, compresseurs ou vannes de détente. La commande développée a ensuite été implantée sur un automate industriel programmable et des expériences ont été réalisées sur deux machines différentes. La première est constituée de deux échangeurs à tubes et calandre et d’un compresseur à pistons, alors que la seconde comprend un évaporateur à plaques, une batterie à ailettes et un compresseur à vis. / An accurate control of fluids flow is essential in any refrigeration system. As the conventional Proportional-Integral-Derivative (PID) control with invariable parameters can lead to unsatisfactory performance because of the variation of refrigeration unit parameters under disturbances, the aim of the work presented here is to develop a method for using Predictive Functional Control (PFC) to regulate the evaporator superheat, the condensing pressure and the cooling capacity on a variable-speed refrigeration system. Using a predictive controller requires to predic future change at the output of the process. This prediction is based on an internal model used as known model. By assuming that the behaviour of refrigerating machine heat exchangers can be represented using a first-order model, the implementation of PFC requires only three parameters: gain, time constant and time delay. In order to determine these parameters an original method has been developed which is based on the physical modelling of the machine. Physical models for different types of evaporator, condenser, compressor or expansion valve have been established to quantify heat transfer and refrigerant flow rate in these components. The control system created has been incorporated into an industrial programmable logic controller and used for experiments on two different refrigerating machines: the first one is composed of two shell and tube heat exchangers and a reciprocating compressor, whereas the second one is composed of a plate evaporator, a finned-tube condenser and a screw compressor. The tests performed show that PFC controller succeed in maintaining a precise chilled liquid temperature.

This research assessed the perceived and actual roles of Faith-Based Organizations (FBOs) in their community and in working with offenders and their families in relation to the Criminal Justice System (CJS). Additionally, the research study evaluated this issue on the local level in an attempt to ascertain whether FBOs still do what they have historically been perceived to do or whether their involvement with the CJS has shifted in any way. Particularly, the research study also examined perceptions of staff members from FBOs regarding services and support provided for families of offenders. The sample was selected using a combination of convenience and snowball sampling. Group sizes ranged from 2-5 participants. A total of 14 participants interacted in the focus groups. Each focus group lasted approximately one hour. All focus groups were recorded using a digital audio recording device, and transcriptions of the focus groups were prepared. The transcripts were prepared using a combination of edited and intelligent transcription techniques. Researchers reviewed the transcriptions for recurring themes. Twenty-four initial themes were generated. Researchers then reviewed the themes for redundancy which resulted in 10 themes being identified. The transcripts were then coded based on the 10 revised themes. These themes focused on issues related to the perceived and real roles of FBOs in relation to the Criminal Justice System. As expected, the researchers found that FBO programming difficulties and concerns (f = 65) and misperception and lack of church involvement in the lives of offenders and the CJS (f = 50) were the most recurring themes. Miscommunication and lack of connection between the CJS and community was found to be the third most recurring theme (f = 15), followed closely by lack of reunification of offenders with their families (f = 14). Perceptions of participants such as clergy and mental health practitioners confirmed the researcher’s expectations that offenders often express deep anxiety and concern over being separated from their families. Thus, current programming efforts may reflect a lack of emphasis on services designed to rejoin offenders with their families or reintegrate them in family systems based on participants’ perceptions. Analysis of the data is ongoing. Researchers will return to the data to further discuss theme coding and to determine if additional themes emerge. All identified themes will be further assessed for inter-rater reliability.

Using participant observation, in-depth interviews, and legislative histories, we examine Westboro Baptist Church, a religious group infamous for homophobic rhetoric and funeral protests. Employing cultural and interactionist perspectives that focus on the semiotics of death, the sacred, and desecration, we outline how Westboro’s activities purposively violate deeply held signifiers of moral order through language, while simultaneously respecting extant laws of behavior. This strategy, in conjunction with the political profitability of opposing the group, explains why the group’s activism triggered extensive legal disputes and modifications at multiple levels of governance. Westboro’s actions and use of symbols—and those of others against the group—lay bare multiple threads in the sacred cultural fabric of American society.

Book Summary: Does theism dominant the language and practices of public life in the United States? This volume explores this question from a humanist perspective, and in so doing it provides insight into the relationship of religion to public policy, and offers ways to advance a more democratic and secular public arena.

Research on the topics of atheism, agnosticism, and irreligion has been limited during much of the last century. We explain the reasons for a lack of research in this field and discuss the recent interest in this topic. The most recent wave of research has been concentrated during the past decade and tends to look at the dual issues of who composes the religiously unaffiliated and why they choose this self-identification. Recent research has begun to take a much wider and deeper view on the subject. This includes research on particular segments of the population such as atheists, as well as understanding how the religiously unaffiliated are viewed by the broader culture. We conclude by describing important directions for future research. In particular, there is a need to break out the separate forms of irreligion and use creative new methodologies to find and study this significant portion of the population.

Gender gaps in religiosity among Western populations, such that women are more religious than men, are well documented. Previous explanations for these differences range from biological predispositions of risk aversion to patriarchal gender socialization, but all largely overlook the intersection of social statuses. Drawing on theories of intersectionality, we contribute to the cultural and empirical analysis of gender gaps in religiosity by documenting an interactive effect between gender, education, and political views for predicting religious nonaffiliation and infrequent attendance at religious services among Americans. For highly educated political liberals, gender gaps effectively disappear, such that men and women are almost equally likely to be secular (or religious). The results have implications for the long-standing disputes about the gendered “nature” of religiosity and highlight the importance of multiple intersecting statuses and modalities in shaping aggregate patterns of religiosity and secularity.

Book Summary: The Routledge Handbook on Deviance brings together original contributions on deviance, with a focus on new, emerging, and hidden forms of deviant behavior. The editors have curated a comprehensive collection highlighting the relativity of deviance, with chapters exploring the deviant behaviors related to sport, recreation, body modification, chronic health conditions, substance use, religion and cults, political extremism, sexuality, online interaction, mental and emotional disorders, elite societal status, workplace issues, and lifestyle. The selections review competing definitions and orientations and a wide range of theoretical premises, while addressing methodological issues involved in the study of deviance. Each section begins with an introduction by the editors, anchoring the topics in relevant theoretical and methodological contexts and identifying common themes as well as divergence. Providing state-of-the-art scholarship on deviance in modern society, this handbook is an invaluable resource for researchers and students engaged in the study of deviance across a range of diciplines including criminology, criminal justice, sociology, anthropology, and interdisciplinary departments, including justice studies, social transformation, and socio-legal studies.

There is an overrepresentation of youths with disabilities in the juvenile justice system. As a result, each year thousands of juvenile offenders despite of the seriousness of the crimes committed, are released from incarceration with the hopes of living a successful life in society. Despite progressive research on identifying factors associated with desistance, it is still unclear what factors contribute to desistance for serious juvenile offenders and especially those with disabilities. The current study investigated the individual differences (e.g., moral disengagement, motivation to succeed and impulse control) and social factors (e.g., employment, education and maternal warmth) that are important in the process of desistance for serious juvenile offenders. The sample of 14 to 17-year-old male and female offenders (N =1354) was composed primarily of ethnically marginalized youths who have committed serious offenses. Results of the study indicated that both social and individual factors are significant predictors of desistance from crime. However, varied significance was found as it relates to Aggressive, Income Offending and desistance. Results obtained are applicable to scholarship across multiple disciplines, as well as inform policy, practice and future research on desistance from crime. Limitations of the study were also stated.

This dissertation explores the mechanisms of the increasing female crime in China from the effect of the one-child policy, which is treated herein as a natural experiment. Data reveal that the women’s share of documented crime dramatically increased after the mid-1990s when the first one-child generation reached the age of legal responsibility. This change reflects the interplay of the behavioral change and the net-widening effect. The increasing criminality of the one-child generation is attributable to the gap between the equal gender expectations of the individual, which has been reshaped by the unique socialization practices under the influence of the policy, and a stubbornly unequal gender hierarchy in the society. As a result, the one-child-generation women who disproportionately suffer the resulting strains are more likely to become involved in property and occupational crime as the alternative means to fulfill their aspirations for economic success. Additionally, the effect of the policy affects not only the individual gender roles of the only children but also their peers who have siblings through the intermediary of a culture shift. Therefore, the policy has changed the behavior of a whole new generation through the process of socialization and the lag in the structural change. The net-widening effect is another pathway of the unequal gender structure and ideologies to the increasing female crime. Moral panic associated with the emergence of diverse forms of female offenses lead to an inordinate degree of adverse attention focused upon the one-child-generation women by criminal justice professionals. The increased criminalization of sexuality brought an increasing number of the one-child-generation women into conflict with the law, usually for prostituting themselves for easy money to fulfill their material satisfaction. Consequently, the one-child-generation female offenders are perceived as “doubly deviant” from the law and from the socially prescribed ideology of gender and are, therefore, punished more harshly than before by the criminal justice system. This dissertation not only explores an understudied country in criminological research but also seeks to apply the findings to a broad sphere to explain the increasing female crime that has been observed worldwide. It disentangles the theoretical controversy in explaining the increase in the share of crime committed by women in general by embedding the argument in a multidimensional gender role repertoire.

This three-paper dissertation quantitatively identifies and examines three different substantive areas using data from the American College Health Association’s Fall of 2016 National College Health Assessment (ACHA-NCHA). Specific areas of inquiry include, marginalized populations and college campus sexual assault, intersectional analyses of risk factors for college campus sexual assault, and drinking protective behavioral strategies as prevention tools for college campus sexual assault. Paper one, titled, “College Campus Sexual Assault and Students with Disabilities,” explores a particular marginalized group of students that have been largely left out of college campus sexual assault studies: female college students with disabilities. The logistic regression analyses find that having any disability increases risk for any type of college campus sexual assault more than other commonly cited risk factors such as binge drinking, or Greek affiliation. Moreover, the study indicates that odds for female students with disabilities are varied depending on the type of assault, completed, attempted, or relationship, as well as the specific type of disability. Results are discussed, and policy implications, limitations, and opportunities for future research are delineated. Paper two, titled, “College Campus Sexual Assault: Moving Toward a More Intersectional Quantitative Analysis,” is guided by an intersectional theoretical framework. The study employs classification and regression tree analyses (CART) to identify more specific groups of students that are at disproportionate risk for sexual assault beyond singular variables or even interaction effects. Unlike traditional regression techniques, CART does not assume a linear relationship, and can simultaneously account for independent variables relationship to one another while determining which variables have the most explanatory power for the dependent variable and for which unique groups of students. The study discusses results of analyses in relationship to intersectional research both theoretically and methodologically, as well as future research, and policy implications. Alcohol consumption, particularly binge drinking, has been consistently linked to greater risk for college campus sexual assault victimization. However, there is a lack of college campus violence prevention and intervention programming that addresses alcohol consumption in relation to campus sexual assault. As such, paper three, titled, “Drinking Protective Behavioral Strategies and College Campus Sexual Assault,” uses logistic regression to explore whether or not the use of drinking protective behavioral strategies (PBS) lowers risk for sexual assault in female college students that drink alcohol. The study examines both the main effects of drinking PBS on sexual assault risk, as well as whether or not the use of drinking PBS moderates the risk of frequent alcohol consumption, and binge drinking on college campus sexual assault. The paper discusses findings, limitations, policy implications, and avenues for future research.
