Intervention dans le processus de réinsertion sociale au Québec : une étude du point de vue des agents de réinsertion sociale en collectivité

Ce mémoire a pour objectif de comprendre l’expérience de travail des agents œuvrant en réinsertion sociale auprès de condamnés provinciaux en collectivité au Québec. Plus précisément, cette recherche souhaite saisir le rôle exercé par ces agents, dans un contexte où ils exercent un double mandat de sécurité publique et de réinsertion sociale. L’étude tente aussi de mettre en lumière leurs pratiques de travail, inscrites dans une logique de gestion efficace des risques. Enfin, ce mémoire vise à comprendre la place qu’occupe la réinsertion sociale dans le cadre de leur travail. Pour ce faire, l’approche qualitative a permis de mener quinze (15) entretiens auprès d’agents de probation et d’intervenants issus du secteur communautaire responsables de la surveillance de justiciables provinciaux en collectivité. Deux (2) thèmes principaux émergent de ces entrevues. D’une part, Le travail est décrit par les participants en regard du double rôle exercé, des responsabilités légales et cliniques qui leur incombent, et de l’intervention centrée sur le risque et la réinsertion sociale auprès des contrevenants. D’autre part, Le contexte de travail réfère au partenariat établi entre les intervenants, au recours aux outils actuariels, ainsi qu’aux instances modulant leurs pratiques de travail : les médias, la Commission québécoise des libérations conditionnelles et les Services correctionnels du Québec. Il ressort de nos analyses que la sécurité publique par la gestion efficace des risques se manifeste par une forme de rationalisation des pratiques de travail et par l’intégration d’un rôle de contrôle. Il appert cependant que ces deux (2) aspects sont motivés avant tout par le désir de venir en aide à la population contrevenante. Il résulte finalement de l’étude que la réinsertion sociale ne constitue qu’un objectif de l’intervention parmi d’autres. Les participants doivent jongler avec ces diverses finalités afin de s’ajuster à l’acteur principal de leur travail : le contrevenant.

De episcopis Hispaniarum : agents of continuity in the long fifth century

En année 408 après J.-C., l’Espagne, malgré sa position péninsulaire à la fin de l’Europe, était intégrée à une culture pan-Méditerranéenne qui s’étendait du Portugal jusqu’à la Syrie. Trois décennies n’étaient pas encore passées depuis l’instauration du Christianisme comme religion de l’état romain et l’Eglise Catholique était en pleine croissance. L’année suivante, l’Espagne entra sur une voie de transformation irrémédiable alors que les païens, avec leurs langues barbares Germaniques franchirent les Pyrénées portant la guerre et la misère aux Hispano-Romains et fondant leurs royaumes là où auparavant gouvernait l’état romain. Dans le désarroi du Ve siècle, les évêques Catholiques luttèrent pour imposer leur dominance dans les communautés et dans les coeurs des pieux. À la lumière des progrès dans l’archéologie et la qualité des éditions critiques de nos sources littéraires est venu le moment d’identifier les évêques ibériques avec une attention aux conditions régionales. Ce mémoire caractérise les évêques de l’Espagne et du Portugal et démontre les épreuves auxquelles ils firent face comme intermédiaires entre indigènes et envahisseurs, comme évangélistes parmi les païens, persécuteurs des apostates et gardiens de la romanitas à la fin du monde Antique.

Cure Characteristics of Short Polyester Fiber-PolyurethaneElastomer Composite with Interfacial Bonding Agents Based on Polymeric 4,4'-Diphenylmethanediisocyanate

Cure characteristics of short polyester fiber-polyurethane composites with respect to different bonding agents (MD resins) based on 4, 4' diphenylmethanediisocyanate (MDI) and various diols like propyleneglycol (PG), polypropyleneglycol (PPG) and glycerol (GL) were studied. Tmax. - Tmin. of composites having MD resin were found to be higher than the composite without MD resin. Minimum torque and Tmax. - Tmin., scorch time and optimum cure time were increased with the increase of MDI equivalence. Optimum ratio of MDI / -of in the resin was found to be within the range of 1-1.5. It was observed from the cure characteristics that for getting better adhesion between short polyester fiber and the polyurethane matrix the best choice of MD resin was one based on MDI and 1:1 equivalent mixture of polypropyleneglycol and glycerol.

Rheological Properties of Short Polyester Fiber-Polyurethane Elastomer Composite with Different Interfacial Bonding Agents

The rheological behavior of a short-polyester-fiber-filled polyurethane elastomer composite containing different bonding agents has been studied in the temperature range 120-160°C and in the shear rate range 63-608 s-'. The composite with and without bonding agents showed a pseudoplastic behavior which decreased with the increase of temperature. Composites containing bonding agents based on polypropyleneglycol and 4,4'-diphenylmethanediisocyanate showed the lowest viscosity values at a particular shear rate, whereas composites containing a glycerol- (GL) based bonding agent showed the highest viscosity. The viscosity of the composite decreased sharply after a particular temperature (140°C) and the fall was less drastic in the composite containing a GL-based bonding agent.

Stress Relaxation of Polyester Fiber-Polyurethane Elastomer Composite with Different Interfacial Bonding Agents

The stress relaxation behavior of polyurethane elastomer and short polyester fiber filled elastomer composites with and without bonding agents at different strain levels and strain rates was studied. It was found that these compounds exhibit a multistage relaxation mechanism and that the rate of relaxation and cross-over time depend on the strain level and strain rate. The incorporation of fibers reduced the stage-I relaxation rate and increased the cross-over time of the gum vulcanisate. A higher rate of relaxation (first stage) was shown by the composites with longitudinal fiber orientation and composites with bonding agents.

Studies on the curing of short polyester fiber-polyurethane elastomer composite with different interfacial bonding agents

The cure characteristics of short fiber-polyurethane elastomer were studied with respect to different fiber-matrix bonding agents. A hexamethylenetetramine- resorcinol -hydrated silica based bonding agent was found to affect the stability of the composite. A new bonding agent, TP resin, based on polymeric toluenediisocyanate and polypropylene glycol has been developed. Cure characteristics of the composite with and without TP resin at different fiber loadings were also compared. Minimum torque, scorch time and optimum cure time increased with fiber content. Maximum torque was consistently higher with TP resin at all fiber loadings.

A comparative study on aniline alkylation activity using methanol and dimethyl carbonate as the alkylating agents over Zn–Co–Fe ternary spinel systems

The catalyst compositions of the Zn1−xCOxFe2O4 (x= 0, 0.2, 0.5, 0.8 and 1.0) spiel series possessing ‘x’ values, x less than or equal to 0.5, are unique for selective N-monomethylation of aniline using methanol as the alkylating agent. Since dimethyl carbonate (DMC) is another potential non-toxic alkylating agent, alkylation of aniline was investigated over various Zn–Co ferrites using DMC as the alkylating agent. The merits and demerits of the two alkylating agents are compared. Catalytic activity followed a similar trend with respect to the composition of the ferrospinel systems. DMC is active at comparatively low temperature, where methanol shows only mild activity. However, on the selectivity basis, DMC as an alkylating agent could not compete with methanol, since the former gave appreciable amounts of N,N-dimethylaniline (NNDMA) even at low temperature where methanol gave nearly 99% N-methylaniline (NMA) selectivity. As in the case of methanol, DMC also did not give any C-alkylated products.

Marine Actinomycetes as Source of Antiviral Agents and as Probionts for Penaeus monodon Culture Systems

The present study revealed the importance of marine actinomycetes as a potent source of bio active secondary metabolites. The selected isolates were capable of protecting Peaneus monodon against WSSV infection. They also proved to be inhibitory to vibrios and is a rich pool of hydrolytic enzymes. Their capacity to proliferate in saline environments and their property of non-pathogenicity to prawns makes them good candidates to be applied as probionts in penaeid shrimp aquaculture. They also enhanced the immune status of shrimps challenged with WSSV and act as a good source of antioxidants. Exploitation of the potential for the prophylactic and therapeutic measures in aquatic animal health management would be highly rewarding. This work is a preliminary study targeting marine actinomycetes as a source of antiviral compounds and as probionts in Penaeus monodon culture systems. More work is needed to understand the nature and mode of action of the bioactive compound, the various aspects of immune and antioxidant responses under challenge and when exposed to pro active treatments, and the dose and frequency of application of such compounds under rearing conditions.

Studies On Vulcanization, Rheology And Reinforcement Of Natural Rubber Latex With Special Reference To Accelerator Combinations, Surface Active Agents And Gamma Irradiation

In the present work, studies on vulcanization, rheology and reinforcement of natural rubber latex with special reference to accelerator combinations, surface active agents and gamma irradiation have been undertaken. In vulcanization, the choice of vulcanization system, the extent and mc-zie of vulcanization and network structure of the vulcanizate are important factors contributing to the overall quality of the product. The vulcanization system may be conventional type using elemental sulfur or a system involving sulfur donors. The latter type is used mainly in the manufacture of heat resistant products. For improving the technical properties of the products such as modulus and tensile strength, different accelerator combinations are used. It is known that accelerators have a strong effect on the physical properties of rubber vulcanizates. A perusal of the literature indicates that fundamental studies on the above aspects of latex technology are very limited. Thereforea systematic study on vulcanization, rheology and reinforcement of natural rubber latex with reference to the effect of accelerator combinations, surface active agents and gamma irradiation has been undertaken. The preparation and evaluation of some products like latex thread was also undertaken as a part of the study. The thesis consists of six chapter
