Je propose la première étude quantitative des corrections radiatives du modèle EPRL en gravité quantique à mousse de spins. Ce modèle est la proposition la plus élaborée de gravité quantique Lorentzienne 4D dite 'indépendante du fond' ('background independent'). C'est une réalisation, par intégrale de chemin, de la quantification de la Relativité Générale comme somme sur les géométries. L'étude se focalise sur les propriétés et les aspects géométriques de l'analogue du graphe de self-énergie du modèle, connu comme le graphe 'melonique'. Je montre que les contributions dominantes à un tel graphe divergent beaucoup moins que celles de modèles similaires en théorie topologique des champs. De plus, je dérive en détails la dépendance des amplitudes aux données de bords, et montre que ce graphe n'induit pas une renormalisation de la fonction d'onde. Ceci est dû à des raisons reliées aux fondements du modèle. Cependant, il se trouve que l'amplitude se réduit à une telle renormalisation dans la limite de nombres quantiques élevés. Ensuite, je montre les conséquences de ces calculs sur une observable physique : la fonction à deux points de la métrique quantique. Ainsi, je montre comment l'insertion du graphe de self-énergie dans l'intérieur de la mousse de spins utilisée a des effets non-triviaux sur la fonction à deux points, modifiant ses contributions à l'ordre dominant. De façon intéressante, ces effets ne disparaissent pas dans la limite des nombres quantiques élevés. Enfin, je discute les conséquences de ces calculs pour le modèle lui-même, et je souligne et commente les traits généraux qui semblent commun à tout modèle de mousse de spins basé sur le schéma présenté ici. / I present the first quantitative study of radiative corrections within the EPRL model of quantum gravity. This model is the most advanced proposal of Lorentzian 4-dimensional background-independent quantum gravity. It is a realization of the path-integral quantization of general relativity as a sum over geometries. The present study focuses on the properties and geometrical features of the analogue of the self-energy graph within the model, often referred to as the "melon"-graph. Here, I show that the dominating contribution to such a graph is characterized by a degree of divergence much smaller than that of closely related topological quantum field theories. Moreover, I work out in detail the dependence of the amplitude from the boundary data, and find that the self-energy graph does not simply induce a wave function renormaliziation. This happens for reasons deeply related to the model foundations. However, it turns out that the amplitude reduces to a wave function renormalzation in the limit of large quantum numbers. Then, I show the consequences of this calculations on a concrete spinfoam observable: the quantum-metric two-point function. In doing this, I show how the insertion of the self-energy graph in the bulk of the (first-order) spinfoam used in the calculation, has non-trivial effects on the correlation function, modifying its leading order contributions. Most interestingly, this effects do not disappear in the limit of large quantum number. Finally, I discuss the consequences of these calculations for the model itself, and I point out and comment those general features which seem to be common to any spinfoam model based on the present model-building schemes.

In the past twenty years boot camps have been evaluated for effectiveness on reducing recidivism, crowding, and costs to the Departments of Corrections. Program and offender characteristics have been studied. This analysis intends to determine how well studied boot camps are, why there is so much disagreement in the findings, and what impact, if any, boot camp programming has had in corrections.

Recent events have given attention to the public perception of criminal justice field in the United States. Although there has been much political debate about problems in the criminal justice field, attention should be turned to the prospective employees who will soon be seeking out these debates: college students seeking to enter the criminal justice field. The current study did that through survey data obtained from 112 students enrolled in criminal justice courses at East Tennessee State University during the Fall 2020 semester. Analysis revealed much about student interest in various criminal justice occupations, their perceived ability to perform the duties associated with them and the factors that motivated their decision-making. It also indicated that certain characteristics may influence desire to enter the policing and legal fields. Each of these findings is discussed.

On t.p.: Master in Social Work (Welfare Programme Management) / Thesis (MA)--Stellenbosch University, 2001. / ENGLISH ABSTRACT: This study attempts to gain insight into the nature of psychosocial stress experienced by correctional officials. In order to achieve this, a literature study was undertaken regarding the nature of psychosocial stress from an ecological perspective as well as strategies that the occupational social worker, management and central government can employ to address stress experienced by correctional officials. Secondly, an empirical study was undertaken and information on the research topic was obtained from correctional officials that worked on the sections inside prisons and who worked directly with inmates. The study indicated that low motivation amongst colleagues, insufficient salaries and bad collegial co-operation were factors that had a major influence on psychosocial stress experienced by correctional officials. Factors such as family responsibilities as opposed to work responsibilities; drug-or alcohol abuse as well as physical constraints have less of an impact on psychosocial stress. It was furthermore found that the need for confidentiality, guidance in stress management and emotional support enjoys a high priority with correctional officials regarding social worker intervention. Issues such as the need that the social worker should form part of a multi-disciplinary team or that he/she should mobilise their colleagues and supervisors for support enjoyed a lesser preference with correctional officials. With regard to the role of management it was found that correctional officials require that management should primarily provide more promotional opportunities and should develop a more satisfactory merit system. Dissatisfaction with the Department of Correctional Services' Employee Assistance Programme and the present shift system were less of a concern to correctional officials. It was concluded that that stressors experienced by correctional officials are varied and include feelings of anger, depression and a general dissatisfaction with managerial styles and certain departmental actions and procedures. It was also very evident that many correctional officials felt that they do not have an appropriate avenue to deal with their stress. If this situation prevails, it was concluded that it will exacerbate correctional officials' poor social functioning. With regard to social worker intervention it was concluded that the vast majority of correctional officials are in dire need of social work intervention to assist them in effectively dealing with stress. It was further concluded that the Department of Correctional Services does not have sufficient structures in place to support correctional officials during stressful periods. Management has a vital role to play in supporting correctional officials when coping with psychosocial stress. If the present situation remains unattended to by management it may impede correctional officials' ability to deal with stress. Recommendations by respondents also indicated a low level of involvement by management in the practical stressors which correctional officials may face. It was also concluded that present attempts by management to deal with psychosocial stress effectively through the induction of an Employee Assistance Programme and the longstanding grievance procedure, have severe practical limitations. Recommendations were made to the social worker, management and central government regarding effectively addressing psychosocial stress experienced by correctional officials working on sections and who are primarily responsible for the guarding of inmates. / AFRIKAANSE OPSOMMING: In hierdie studie is ondersoek ingestel na die aard van psigo-sosiale stres wat deur korrektiewe beamptes ervaar word. Ten einde hierin te slaag,is eerstens 'n literatuurstudie onderneem ten opsigte van die aard van psigo-sosiale stres vanuit 'n ekologiese perspektief. Daar is ook gekyk na strategieë wat die bedryfsmaatskaplike werker, bestuur sowel as die sentrale regering kan aanwend om psigo-sosiale stres wat deur korrektiewe beamptes ervaar word aan te spreek. Daarna is 'n empieriese studie onderneem deur vraelyste aan korrektiewe beamptes te stuur wat direk op seksies binne in gevangenis met gevangenes werksamig is. Die navorsing het aangedui dat lae motivering onder kollegas,onvoldoende salarisse en swak kollegiale samewerking die grootste bydraende faktor is tot psigososialestres wat deur korrektiewe beamptes ervaar word. Faktore soos alkohol- of dwelmmisbruik en liggaamlike gebreke oefen In mindere invloed uit op psigososiale stres wat deur korrektiewe beamptes ervaar word. Met betrekking tot die behoefte aan maatskaplike intervensie is daar bevind dat vertroullkheld, leiding in stres hantering en emosionele steun die hoogste prioriteit by korrektiewe beamptes geniet. Faktore soos die behoefte dat die maatskaplike werker deel moet vorm van 'n multi-dissiplinêre span of dat hy/sy die korrektiewe beampte se kollegas en supervisors moet mobiliseer vir ondersteuning, het 'n mindere prioriteit by korrektiewe beamptes geniet. Met betrekking tot die rol van bestuur, is daar gevind dat korrektiewe beamptes meer bevorderings geleenthede en 'n verbeterde meriete stelsel van bestuur verwag. Ontevredenheid met die Departement van Korrektiewe Dienste se werknemer bystandsprogram (WBP) en die huidige skofstelsel was 'n laer prioriteit vir korrektiewe beamptes. Die gevolgtrekking is gemaak dat stressors wat ervaar word deur korrektiewe beamptes uiteenlopend van aard is en dit sluit in gevoelens van depressie, woede sowel as 'n algemene ontevredenheid met bestuurstyle en sekere departementele aksies en prosedures. Dit was ook baie duidelik dat baie korrektiewe beamptes nie 'n geskikte hulpmiddel het om hulle in staat te stelom psigososiale stres effektief te hanteer nie. Indien die huidige situasie bly voortbestaan, kan korrektiewe beamptes se swak maatskaplike funksionering verder belemmer word. Met betrekking tot maatskaplike werk intervensie ,is gevind dat die oorgrote meerderheid van korrektiewe beamptes 'n noodsaaklike behoefte daartoe het dat die maatskaplike werker hulle moet ondersteun om psigososiale-stres effektief te hanteer. Voorts is die gevolgtrekking gemaak dat die Departement van Korrektiewe I Dienste nie oor toereikende strukture beskik om die korrektiewe beampte te ondersteun tydens stresvolle tydperke nie. Bestuur het 'n noodsaaklike rol in die ondersteuning van die korrektiewe beampte in sy/haar hantering van psigososiale stres. Indien die huidige situasie nie voldoende deur bestuur aangespreek word nie, kan dit die korrektiewe beampte se vermoë om psigososiale-stres te hanteer verder strem. Aanbevelings deur respondente het ook 'n lae vlak van betrokkenheid deur bestuur aangedui by die praktiese stressors wat korrektiewe beamptes mag ervaar. Die gevolgtrekking is ook gemaak dat huidige pogings deur bestuur om psigososiale stres aan te spreek deur middel van 'n werknemer bystandsprogram en die reeds gevestigde griewe prosedure, grootskaalse beperkings het. Aanbevelings is aan maatskaplike werkers,bestuur en die sentrale regering gemaak oor hoe om psigososiale stres wat deur korrektiewe beamptes werksaam op seksies binne in gevangenisse en wat primêr vir die bewaking van gevangenes verantwoordelik is, aan te spreek.
