Full textWe are currently experiencing an aging of the population in the province of Québec. Even though many elders are food insecure, very few of them resort to food aid programs. However, the reasons behind this low take-up are unknown. This study aims to document the food access strategies used by food insecure lone elders living in the Limoilou neighborhood and to better understand the motives behind their use and non-use of several types of food aid programs (food banks, collective kitchens, etc.). We carried out two waves of fourteen individual interviews with food insecure lone elders from Limoilou, which deepened our understanding of their experience. The results of this study suggest interesting avenues for research and intervention to facilitate their access to food and adapt food aid programs to the elders’ needs and realities.

Full textState surveillance of the poor has a long history. It begins several centuries ago, more precisely with the creation of modern nation-states. According to social theorists, the strengthening of the state’s surveillance capabilities results from both mass bureaucracy and democracy. It also stems from people’s desire to assert their civil rights. This thesis examines state supervision from a welfare recipient point of view. It aims to identify recipients’ rationales and practices of resistance. We interviewed 19 participants from both cities of Montreal and Quebec City. Results suggest the extent of resistance at work: two different resistance rationales, as well as six tactical moves emerged from our analysis.

Full textThe Act Respecting End-of-Life Care came into force in Quebec in December 2015. Since that day, a person may, in certain circumstances, apply for medical assistance in dying (MAID). As such, anyone requesting this service has to go through a multistep process. However, as explained in this Act, the main health professionals involved in this process are doctors and the place of social workers is very little discussed and often absent. Therefore, our study aims to answer the following question: What is the role of psychosocial support in the practice of medical aid in dying in Quebec (MAID)? Currently in Quebec, there isn’t any study to our knowledge that is focused on the needs in terms of psychosocial support of a person requesting medical aid in dying. A literature review allowed the study of 273 essays that were filled to the National Assembly of Quebec during the Consultation from the Select Committee on Dying with Dignity. The analytic questioning approach (Paille & Mucchielli, 2012) as allowed the analysis of 20 essays that were selected for our sample because they made recommendations regarding psychosocial support in the MAID. Nonetheless, several observations and recommendations to that effect were not considered during the development of this Act. Based on Kübler-Ross (1969) model known as the five stages of of grief, the results of this study demonstrate the importance of psychosocial support during the medical aid in dying along the continuum care at the end of life, until death. These conclusions highlight the importance of multidisciplinary work in the MAID process, in order to allow optimal support when it comes to the needs of those persons at the end of life, more specifically when assessing the restrictive conditions and decisionmaking. Moreover, the psychosocial support of families during the process is just as important, even after death. Finally, this study highlights the place of social workers in supporting patients and family going through medical aid in dying. -- Keywords: Medical aid in dying, psychosocial support, end-of-life care, five stages of grief of Kübler-Ross

Full textA discrete/continuous choice model is used to analyze the ownership of private motor vehicles and their use in Quebec. The estimation of the discrete choice model is based on the Mixed Logit specification and each of the 224 different vehicle models appears as specific element of the choice set. A generalization of Heckman’s correction term is incorporated in the vehicle use equation for each alternative. The data come from a special survey conducted by the Société de l’assurance automobile du Québec in 1996-1997. The empirical results show that car choice is highly related to driver’s age and fuel consumption. Prices of car do not affect the probability of owning most of vehicle classes, including SUV. Gender, household location, age, and fuel price are among the main determinants of car use.

Full textL’industrie forestière est un secteur économique générant beaucoup d’emplois au Québec, Canada. Dans le but d’assurer la compétitivité et la profitabilité des scieries, plusieurs propriétaires se voient donc dans l’obligation de revoir leurs systèmes de production. De plus, ceux-ci sont à la recherche de nouvelles opportunités pour générer des profits, comme le programme de gestion de la demande en puissance (GDP) d’Hydro-Québec, programme visant à redistribuer l’usage de l’électricité vers des périodes hors-pointe. C’est dans cette optique que s’insère cette maîtrise, dont le but est d’évaluer l’impact technico-économique de l’implantation de stratégies permettant à une scierie typique de participer au programme de GDP. Pour ce faire, une revue de la littérature a été faite, afin d’établir un état de l’art sur les systèmes de gestion de l’énergie en industrie, la gestion de la demande en puissance et les modèles de planification existants dans le milieu de la fabrication de bois d’oeuvre. Ensuite, l’étude d’un système de production de bois d’oeuvre réel et la collecte d’informations quant à la consommation d’électricité des équipements et de chauffage des espaces de travail utilisés ont été réalisées. Ces informations ont par la suite été intégrées à l’intérieur d’un modèle de planification tactique des opérations. Avec un tel modèle, il devenait donc possible de tester différentes stratégies permettant de réduire l’appel en puissance des équipements en cas d’évènement de GDP et de mesurer les gains financiers ou encore les pertes engendrées par la mise en place de telles stratégies. Plus particulièrement, six stratégies ont été testées. À la suite d’une étude comparative basée sur la profitabilité de chaque stratégie, il s’est avéré que le meilleur scénario permettait d’augmenter les profits de la scierie à l’étude de près de 5%, tout en offrant une augmentation de profit durant un grand nombre d’heures de GDP (68 heures). Somme toute, l’étude a permis de trouver, pour une scierie type du Québec, la meilleure stratégie à mettre en place pour participer au programme de GDP d’Hydro-Québec. Elle a également a permis de développer un modèle de planification pour l’industrie du bois d’oeuvre intégrant la facette énergétique et de générer une méthodologie générale permettant de reproduire les travaux réalisés dans le cadre de la recherche à d’autres secteurs.
The forestry industry is an economic sector that generates a lot of jobs in Quebec, Canada. In order to ensure the competitiveness and profitability of sawmills, many owners are therefore obliged to review their production systems. In addition, they are looking into new opportunities to generate profits like Hydro-Quebec's Demandresponse program (DR). It is in this perspective that this master project is integrated, whose aim is to find the best strategy at the level of profitability, for a typical Quebec sawmill, to participate in Hydro-Quebec’s DR program. To this end, a literature review was conducted to establish a state of the art on energy management systems in industry, on demand-response programs and on existing planning models in the lumber manufacturing industry. Then, the study of a real lumber production system and the information collection about the equipment electricity consumption and the workspace heating used were realized. This information was subsequently integrated into a tactical operations planning model. With such a model, it became possible to test different strategies to reduce the equipment power demand in case of DR event and measure the financial gains or the losses generated by the implementation of such strategies. More specifically, six strategies were tested. As a result of a comparative study based on the profitability of each strategy, it turned out that the best scenario allowed the sawmill profits to increase by almost 5% while offering a profit increase for a large number of DR hour (68 hours). All in all, the study found that, for a typical Quebec sawmill, the best strategy to put in place to participate in Hydro-Québec's DR program. It also helped develop a planning model for the lumber industry integrating the electrical energy facet and generates a general methodology for replicating the work done in the present research to other sectors.

Full textLes groupes de traitement de la toxicomanie en milieu carcéral offrent un contexte d’intervention particulier. Bien que plusieurs études abordent leur efficacité, les processus d’intervention qui y prennent place ont été très peu explorés dans les écrits scientifiques. Il devenait alors pertinent d’entreprendre cette recherche, qui tente de saisir l’expérience des hommes qui participent à un groupe psychoéducatif dans le cadre du programme Toxico-Justice offert en milieu carcéral. S’inscrivant dans la perspective de l’interactionnisme symbolique, l’étude utilise l’entretien qualitatif semi-directif afin d’élaborer un portrait subjectif de l’expérience de groupe ainsi que du rôle des interactions dans cette expérience. L’échantillon est constitué de dix hommes ayant complété le programme Toxico-Justice depuis moins d’un an au moment de l’entrevue. Les résultats obtenus ont permis d’analyser la présence de huit facteurs d’aide au sein du groupe : le partage d’information, la connaissance de soi, la cohésion, l’universalité, l’altruisme, la catharsis, la révélation de soi et l’apprentissage par imitation. La présence de ces facteurs d’aide a été modérée par certaines difficultés qui ont teinté les interactions entre les membres du groupe. Le contexte de groupe ouvert ainsi que le contexte carcéral font partie des facteurs qui auraient rendu les interactions entre les membres du groupe plus difficiles. Néanmoins, les résultats montrent que les participants ont atteint l’objectif du groupe, qui est d’approfondir leur réflexion sur leurs habitudes de consommation et de réduire leur risque de récidive en regard des conduites délinquantes associées à la toxicomanie. Différentes pistes sont explorées afin d’amenuiser l’impact des difficultés vécues dans l’expérience des participants.
Prison-based substance abuse treatment groups provide a specific context for intervention. Although several studies address their effectiveness, the group processes of these groups have been little explored in scientific literature. It became relevant to undertake this research, which attempts to capture the experience of men who participate in a psychoeducational group as part of the Toxico-Justice, a prison-based program. Based on symbolic interactionism, the study uses semi-directive interviews to develop a subjective picture of group experience and the role of interactions in this experience. The sample consisted of ten men who completed the Toxico-Justice program for less than one year at the time of the interview. Results highlighted the presence of eight therapeutic factors within the group: information sharing, self-understanding, cohesion, universality, altruism, catharsis, self-disclosure and interpersonal learning. The presence of these therapeutic factors has been moderated by some difficulties encountered in the interactions between the members of the group. The open group context as well as the prison context are among the factors that would have made interactions between group members more difficult. Nevertheless, the results show that participants met the group's objective of deepening their reflection on their using habits and reducing their risk of recidivism in relation to delinquent behaviors associated with drug addiction. Different avenues are explored in order to reduce the impact of the difficulties encountered in the participants' experience.

Full textPlanning for timber supply in Quebec's public forests represents a complex case of a divergent supply chain (Alayet and al., 2015). The customers of this chain can be numerous. They participate in planning by interacting with the Ministry of Forests, Wildlife and Parks (MFFP) which is the supplier of the plans. Customers also interact with each other to coordinate activities leading to the delivery of different products from a stand or tree to different factories. In general and more particularly in the context under study, alignment of objectives and capacities of stakeholders participating in planning is one of the main factors of success in the supply chain (Lee, 2004; Gunn, 2005; Simatupang and Sridharan, 2005; Fawcett and al., 2008; Cao and Zhang, 2013, Wong and al., 2012). Alignment represents the fit, in terms of objectives, structures and processes internally and between the different functions and stakeholders of a supply chain (Wong and al., 2012). In Quebec, potential timber supply and harvested timber show a historical inadequacy, with 30 % or more of the total annual allowable cut of the public forest not being harvested. In addition, the management strategies leading to the allowable cut calculations take little or no account of the economic aspects, which results in dissatisfaction of industrial customers with the value generated by the supply plans. Finally, planning stakeholders express dissatisfaction with the planning process and the value of plans (Gharbi, 2014). The first part of this research, which consists of a descriptive case study, aims to verify if there is a lack of alignment by studying the current planning process and its alignment mechanisms. The process is compared to a conceptual reference framework developed from theoretical concepts collected in the literature and from the main components of the Supply Chain Council's Supply Chain Organizational Reference model (SCOR). Surveys and interviews with forest planners helped to map, describe and interpret the process, and establish concordances and disagreements with the conceptual framework. Although several sub-processes are comprehensively defined by the MFFP, the study shows that the organization of the planning process is not clearly defined. Roles, responsibilities and tasks are broken down and executed in silos rather than fostering the integration of stakeholder capacities. The hierarchical breakdown of planning does not conform to scientific conventions, leading to inconsistencies between planning levels and difficulties in understanding and communicating among stakeholders. The production and supply objectives are not sufficiently clear and defined. Finally, the use of indicators and dashboards is not widespread, which does not facilitate collaboration, adaptation and adjustment. Thus, the feedback and performance measurement mechanisms are deficient. This research allowed us to verify that there is a lack of alignment and identify the main factors involved. The second part of this research aims to propose and test a strategic level planning process focused on the alignment of objectives and planning capacities for woody material supplies from the principles of the conceptual framework adopted. A project was carried out in action research mode. Planning stakeholders were invited to participate in the development of a Regional Timber Production Strategy (SRPB). They were offered a process that put forward principles for aligning objectives and capacities. This approach demonstrates that it is possible to increase stakeholder satisfaction with the planning process by promoting alignment of goals and capabilities, which answers the research question. Although the project (SRPB) only addresses the strategic level of planning woody material supplies in Quebec public forests, we believe that the results of this research, specifically the conceptual framework supporting the configuration of a process, are transferable at the tactical and operational planning scales as well as in other regional contexts in Quebec and elsewhere. We also believe that these findings may inspire approaches to configuring systems and planning processes in other areas where supply planning involves multiple stakeholders. This research project contributes to filling the gap noted in the literature concerning the field of alignment of objectives and capacities in the planning process of the woody material supply.

Full textRemediation actions scoped on the contaminated sediments of Lake Saint-Augustin are essential to control the main internal phosphorus intake that accelerates the eutrophication of the lake. Several restoration scenarios combining hydraulic and mechanical dredging, phosphorus inactivation with alum treatment and active capping using limestone are developed on the most heavily contaminated areas of the lake. The use of multicriteria methods for decision support helps to assess the best restoration scenario on the basis of technical, economic, environmental and social criteria. The inactivation of phosphorus by alum followed by the application of a limestone cap on the most heavily contaminated areas of the lake as well as the hydraulic dredging of these areas with polymerisation and filtration of pumped sediments through a filter bag appear to be the two most efficient scenarios to implement at Lake Saint-Augustin on a large scale. Mechanical dredging scenarios come last, even behind the do-nothing option.

Full textThe numerous negative impacts linked to the democratization of cars in the last century led to rethink transportation systems and transportation planning practices. Transportation systems should be planned to safeguard long-term ecological vitality, provide basic accessibility and ensure equal access to transport services. This is sustainable transportation. Many actions and strategies were proposed in the last decades to implement sustainable transportation. Redesigning streets in favor of active and public transportation is one of these strategies. However, there is currently a gap between the plans, that adopt a sustainable transportation vision, and practices, that still realize unsustainable transportation projects. The different government levels require new decision aid tools to change their decision processes. Multicriteria decision aiding (MCDA) is one method that is more and more discussed in the transportation literature to integrate a holistic perspective to decision processes. In this regard, this thesis studies more specifically the use of MCDA to improve decision processes linked to street redesigns. First of all, a descriptive literature review was conducted to better understand the evaluation methods that are currently used in transportation decision processes. The two main evaluation methods in the field (cost-benefit analysis and MCDA) were examined according to their perceived strengths and weaknesses, to the different ways to combine them and to their abilities to integrate sustainable development principles in the decision processes. To take into account the different conceptualizations of decision-aiding, the results were analyzed according to four decision-aiding approaches based on the concept of communicative action from Habermas (objectivist, conformist, adjustive and reflexive). Subsequently, a method to develop a multicriteria spatial decision support system (MC-SDSS) to prioritize the streets to redesign as Complete Streets was proposed and applied in collaboration with the City of Quebec in Canada. Complete streets is a popular movement in North America for sustainable transportation to design " streets for everyone ". The MC-SDSS was developed during multidisciplinary group workshops (transportation, urban planning, environment, infrastructure, urban design and public participation) gathering Quebec City professionals using the MCDA method MACBETH. The development of the MC-SDSS was split in five phases: (1) structuring the problem, (2) constructing attractiveness scales, (3) deriving scaling constants, (4) validating the model and (5) producing priority maps. The process has been successful. Indeed, Quebec City has been using this MC-SDSS in the elaboration of its Complete Streets strategy since 2017. Following the MC-SDSS developed in Quebec City, a post-project evaluation framework, specific to MCDA, was generated and applied to the MC-SDSS. The evaluation framework is based on five questions: why evaluate?, what to evaluate?, on what is the evaluation based?, how to evaluate? and who is involved in the evaluation?. The evaluation was applied under the form of a series of individual interviews carried with the professionals involved in the development and use of the MC-SDSS. The interviews were about the development, use and future of the MC-SDSS and were analyzed according to the thematic analysis method. Based on the challenges and difficulties identified in the thematic analysis, various recommendations are suggested to improve practices. Finally, to assess the potential to export the development of MC-SDSS to other contexts, the practices and perceptions of professionals from 11 municipalities in the Province of Quebec were documented during multidisciplinary group workshops (infrastructure, transport, urban planning, environment and geomatics). The objectives of these workshops were (1) to create a portrait of current practices for street rehabilitation and redesign to integrate urban planning, transportation and environment and (2) to identify the issues and challenges of developing MC-SDSS in various municipal contexts. The workshops were analyzed by schematizing the current decision processes and by using the causal mapping method. A series of guidelines is proposed to allow the development of MC-SDSS with the municipalities. Those guidelines aim at easing the development of a new type of decision support system for municipalities, but also at allowing the improvement of current municipal decision processes by better integrating the sustainable vision adopted in the politics and plans and the projects realized by the professionals.

Full textThe coagulation process is the first step of the conventional drinking water treatment chain. It is an important treatment step since it affects the efficiency of the subsequent treatment steps namely flocculation, settling, filtration and disinfection. It is relevant to develop decision aid tools to assist operators in the choice of the coagulant dose. This project aims at developing such tools. More specifically, the objective of the study was to provide tools for the operators of the Sainte-Foy water treatment plant to help them in choosing the appropriate aluminum sulphate dose (alum). As part of this project, three tools were developed: a model for the prediction of the coagulant dose, two models for the prediction of dissolved organic carbon (DOC) concentration of settled water and a virtual sensor which allows predicting DOC concentration of raw and settled waters. All models are neural network models. The first model allows the prediction of the alum dosage by mimicking the good previous operation performed at the plant in terms of turbidity reduction. The input variables of the model are the month, the conductivity, temperature, turbidity and pH of raw water. The model was developed from operation data collected every 5 minutes during 4 years (378 535 data sets). Dosages predicted vary by an average of 5,9% of those actually applied. The second model allows the prediction of the DOC of the settled water. The input variables are the UV absorbance and DOC of raw water, pH of coagulation and alum dosage applied. Performances of the second model are compared with those obtained from two others empirical models (from the literature) that allow the prediction of the DOC of the settled water. Compared to these models, the second neural model gives better prediction performance. DOC concentrations predicted by the second model vary by an average of 9,6% of those actually measured. The third model allows the prediction of the DOC of raw and settled water. The input variables are the UV absorbance, temperature, turbidity and pH. The model acts as a virtual sensor of DOC concentration and allows the evaluation of the removal efficiency of natural organic matter by the coagulation, flocculation and settling steps. DOC concentrations predicted by the third model vary by an average of 13,2% of those actually measured. Finally, the fourth model allows the prediction of the DOC of settled water from UV absorbance of raw water instead of DOC. Concentrations predicted by that model vary by an average of 10,7% of those actually measured. The database for the adjustment of the second, third, and fourth models includes one year of DOC and UV absorbance monitoring at raw and settled water performed twice daily and operation data continuously collected. The models performances are presented and discussed according to their implementation and use in the treatment plant. A way to improve developed models is also described. Actually, only the first model could be implemented on a short term basis. Models 2, 3 and 4 are actually preliminary models that would need to be updated with larger databases including more variation periods before implementation. Developed models could be integrated to allow the operators to choose the alum dosage that can afford to make a compromise between the different objectives of the coagulation process. This could further improve the treated water quality.

Waiting times for health care are a major health policy concern in many industrialized countries. In Quebec, the median time between a referral from a general practitioner and an appointment with specialist was 7.3 weeks in 2012, compared to 2.9 weeks in 1993, despite increases in number of physicians over the same period. For policy makers contemplating such outcomes, it is of particular importance to understand the structure of physician labour supply and how it affects the supply of health services. I consider two main policies in this respect. First, I estimate how physicians react to monetary incentives and I use my estimates to consider how compensation policy can be used to determine the short-term supply of services. Second, I consider how physician productivity is affected by experience, through learning-by-doing, and I use my estimates to determine how many inexperienced physicians must be hired to replace a retiring experienced physician in order to keep the supply of services constant. My dissertation develops and applies economic and statistical methods to measure the reaction of physicians to monetary incentives and to estimate their productivity profiles (measuring how productivity varies with experience throughout a physician's career) using survey and administrative panel data on Quebec physicians. Our data contain information on the labour supply of each physician, the different types of services they produce and their prices. These data cover a period during which the Quebec government changed the relative prices of medical acts. I use a model-based approach to develop and estimate a structural model of physician behaviour with multitasking. In my model, physicians take the prices of different services as given and choose the number of hours they wish to work as well as how those hours are distributed across different services. The model generates an earnings equation that depends on the total hours worked and a price index that gives the marginal return to hours when hours are optimally distributed across services. The price index depends on the prices of services and technology parameters that determine how physicians react to changes in relative prices. I apply the model to panel data on payments to Quebec physicians matched to time-use data on the same physicians. I use the model to investigate two dimensions of the supply of health services. First, I look at the use of monetary incentives to induce physicians to alter their supply of different services. While previous studies have often sought to compare physician behaviour across different compensation systems, relatively little is known about how physicians respond to fee changes. Recent debates in Canadian health policy circles have focussed on the importance of income effects in determining the response of physicians to fee increases. My work contributes to this debate by identifying and estimating the substitution and income effects resulting from changes in the relative fees paid for services. Second, I look at how experience affects physician productivity. This has important implications for the hiring of physicians to meet increased demand from an ageing population, particularly when experienced physicians are retiring. First, I estimate the earnings function conditional on hours worked, using instrumental variables to control for the potential endogeneity of hours worked. As instruments, I use dummies of age, marginal tax rate, returns on market investments, its squared and cubed. I show that this provides a lower bound to the own-price elasticity of any particular service. This allows me to test if physicians respond to monetary incentives. I find that the lower bounds of own-price elasticities of services are positive and statistically significant, suggesting that physicians do respond to monetary incentives. A relative change in prices leads physicians to supply more of the services whose prices have risen. Second, I estimate the full model by explaining the variation in hours worked by physicians, the volume of services supplied, and individual earnings. I do so using a Simulated Method of Moment estimator. The results show that the own-price elasticities for services are large and positive, implying that the volume-increasing response of services to their own-price is strong. Cross-price elasticities are also large but negative. Furthermore, there is an income effect associated with fee increases. I use the structural model estimates to simulate the total effect of a recently observed price increase that was offered to physicians in Quebec, increasing the prices of all services by 32%. The results show that physicians would reduce their total hours worked (average elasticity of -0.02) and clinical hours worked (average elasticity of -0.07). They would also reduce the volume of services provided (average elasticity of -0.05). Third, I exploit the link between fee-for-service physicians'earnings and their productivity to estimate physician productivity profiles. To do so, I modify the specification of the modelto take into account the relationship between a physician's productivity and his/her experience. I estimate the earnings equation using an unbalanced panel dataset, correcting for non-randomly missing observations by estimating a selection model. The results suggest that productivity profiles are increasing concave functions of experience. Furthermore, the shape of the profile is robust to parametric assumptions. A one-year increase in experience increases the production of services by approximately 1,003 CAN dollars. I use the model estimates to calculate the replacement ratio: the number of inexperienced physicians needed

Full textEnergy utilities such as Gaz Métro and Hydro-Québec must ensure that the capacity of their network is sufficient to satisfy the needs of its customers. When the distribution networks are used at full capacity and the demand for energy increases, these companies have the choice of investing to increase their capacity or encourage their customers to consume less. Investments can be deferred by offering customers energy efficiency programs that reduce demand. Historically, the two distributors and the Régie de l’énergie who supervised them preferred to increase the capacity of their respective networks in order to secure the supply of their customers, especially because they felt like it was not possible to adequately control energy demand. Moreover, as business incomes increase with demand, these firms have no incentive to attempt to reduce it. In this paper, I propose a method for estimating the profitability of an active deferral strategy for an investment aimed at increasing the capacity of distrubution networks coupled with an incentive mechanism. My method combines the updated assessment of the costs and benefits of the investment with a pattern of consumer behavior.

Full textNatural ventilation is a passive strategy, i.e. without mechanical means, that can maintain a comfortable interior environment. The aim of the current research is to develop a method allowing designers to understand, at the preconceptual stage and in a cursory fashion, the influence of key architectural features on the capacity to cool down a building by natural ventilation. A computer based tool developed in the framework of this research, HUVENT, helps designers of naturally ventilated buildings to evaluate the effect of building orientation, opening localization and sizing. A validation study of the tool has been completed and is part of this master’s thesis. With the countdown on global warming well underway and keeping in mind that opportunities for natural ventilation will be increasingly restricted, this research presents the favourable period for passive cooling in Quebec climate.

Full textIn this thesis, we assess the effect of employment assistance programs on the number of exits from social assistance and the cumulative duration spent outside of it among beneficiaries living with severe constraints. It is obvious that not all beneficiaries will derive the same benefits from participating in a program and for this reason it is useful to assess treatment effects conditional on the characteristics of each individual. To answer the research question, we need a flexible method that allows us to estimate differentiated treatment effects based on individual characteristics. To do this, we use a machine learning technique called generalized random forests (grf ) allowing us to evaluate heterogeneous treatment effects by conditioning on the characteristics of individuals. We used a database provided by the Ministère du Travail, de l’Emploi et de la Solidarité sociale (MTESS) containing monthly observations of all recipients of social assistance between 1999 and 2018 in Quebec. Using the grf method and the MTESS database, we found that beneficiaries with the longest cumulative durations on social assistance had lower treatment effects than those with shorter durations. We also observed that the younger and more educated beneficiaries benefited more from program participation than the others. This is also the case for individuals who have an auditory diagnosis and those who do not have an organic diagnosis.

Full textEmotion regulation strategies (ERS) are used to modulate emotions and emotional processes in different ways and for different purposes. Some ERS focus on the situation that can trigger emotions while others target the emotions themselves once they have emerged (Gross, 2015). In some circumstances, the difficulty to cope with the situation generates negative emotions which, if not adequately regulate, accentuate the adaptation problem. In clinical perspective, emotional vulnerability is characterized by a high sensitivity to emotional stimuli, an intense response to emotional stimuli and a slow return to emotional baseline. People with high emotional vulnerability have difficulty to keep emotion in optimal zone that can be manageable. These people have a limited access to coping strategies (Linehan et al., 2007). Considering these elements, what role do ERS play in the process of change in relation to the situation and emotions? To explore these questions, we conducted 13 deep case studies in qualitative setting. The participants were 13 men who had consulted a psychotherapist or a social worker at least five times in the past year and signed a confidentiality agreement with the researcher. Inspired by Stake’s (2006) case study method, we had three sharing sessions (two interviews and a writing feedback) with each participant to reconstruct their own process of change retrospectively. The qualitative data were analyzed with MAXQDA-11 and interpreted on the basis of the ERS model of Linehan et al. (2007) and following the method of thematic analysis (Paillé et Mucchielli, 2012). The process of change described by participants indicates a significant improvement in their emotional state and the situation with which they initially struggled to adapt. To explain theses change, the participants believed that psychotherapy helped them to identify maladaptive ERS (rumination, suppression, alcohol, etc.) and progressively replaced these by adaptive ERS (reappraisal, problem-solving, etc.): “I prefer to talk to someone than to ruminate. I prefer to take a time out than to stay inactive” (Francesco). Furthermore, participants said they had learned to make a conscious choice to stop maladaptive ERS and took the risk to use new adaptive ERS (positive expression of emotion, acceptance, meeting their needs, etc.): “When I realized the benefits of evacuating frustration, sadness and negative emotions, I felt wow! I felt good when expressing my emotions, I felt better than when keeping them inside me” (Martial). From the perspective of the participants, psychotherapy helps to reduce emotional vulnerability, which facilitates emotional regulation and adjustment to the situation: “My psychotherapist is part of my team to be able to create strengths, to give me the tools to be able to face different types of individuals in different contexts with better strategies” (Paul). The results of this qualitative study support the idea of Linehan et al. (2007) that psychotherapy, by promoting the adoption of adapted ERS, reduces the emotional vulnerability and promotes adjustment. More specifically, this study shows that the ERS used affect the trajectory of the change process. Thus, the almost exclusive and frequent use of maladaptive ERS corresponds to regression cycles (left wheel) whereas the regular use of adaptive ERS coincides with cycles of progression (right wheel). Moreover, as Linehan (1993) suggests, different interventions would favor the adoption of adapted ERS. The present study agrees in the same direction by associating these interventions with the process of change. Finally, this study explains how ERS facilitates adaptation by acting on both emotions and the situation that generates them. The proposed explanatory model differs from that of Gross (2015) and of Linehan et al. (2007) emphasizing the role of ERS in the process of change as seen by men who have consulted a psychotherapist. However, this model remains to be validated more widely because it was developed from a small number of male participants who perceived a positive role for emotions during their psychotherapeutic process. It would be interesting to interview women or men who believe more or less important the role of emotions in their process of change in order to see their specific way of using the ERS.

Full textThe construction industry represents a major sector for the Quebec Province, subject to constant technological advances as well as social and environmental pressure. It is in line with this dynamic that many companies are currently looking for answers to the performance problems of the traditional delivery system, highlighted by the drop in activity of recent years. In this context, this research focuses on the development of a framework for the Design-Build delivery system. This system aims at integrating both design and construction competences in a single entity responsible for the entire completion of the project. In particular, the project introduces a decision support tool that may help the user to determine if a project is adapted to the use of the Design-Build delivery system, taking into account the project characteristics as well the companies involved. To develop such a tool, the Design-Build delivery system was first compared to the traditional Design-Bid-Build system in terms of cost performance, schedule and quality, to determine its positive and negative aspects. The impact of the method on the different stakeholders of the project was then considered in order to identify the requirements of such an organization on the actors of the project. A series of interviews allowed to validate the previous results while providing further details on the particularities of the Quebec situation, which led to the development of the framework for the application of the method. This framework has finally been translated into a decision support tool to facilitate its use.

Full textSince the early twentieth century, natural outdoor and adventure settings have been used in education and psychosocial intervention (Gass, Gillis, & Russell, 2012; Miles & Priest, 1999; Russell & Hendee, 2000; Tucker & Norton, 2013). Predominantly utilized by groups with educational and therapeutic aims, some effects on individuals taking part in those programs with personal and interpersonal plans have been reported, notably on selfperception (Whittington, 2006), self-efficacy (Ronalds & Allen-Craig, 2008; Török, Kökönyei, Károlyi, Ittzés, & Tomcsányi, 2006), social skills and leadership (Sibthorp, 2003; Stott & Hall, 2003). These effects demonstrate the relevance of this type of intervention. Certain underlying elements of reported effects have been identified, such as the importance of the group in the experience of participants (Deane & Harré, 2014; Scheinfeld, Rochlen, & Buser, 2011), but there is much left to be understood about the group’s place in natural outdoor and adventure experiences. Considered to allow in-depth examination of operating processes in groups, the Helping Factors model developed by Yalom et Leszcz (2005) provides a conceptual framework that is open to possibility. Defining the processes acting within a group as underlying the individual benefits taken away by members, this conceptual framework permits an understanding of what participants encounter in experiences in natural outdoor and adventure settings. Conducted with 23 college students, this qualitative research aims to identify the active Helping Factors in an educational program that takes place in natural outdoor and adventure settings. This general objective can be broken down into two specific objectives: 1) To identify which Helping Factors emerge in group interventions in experiences in natural outdoor and adventure settings; and (2) to determine their relative importance, according to the perspectives of the participants. The results obtained demonstrate a strong presence of the majority of the Helping Factors proposed by Yalom and Leszcz (2005). Interpersonal Learning, Development of Socializing Techniques and Cohesiveness are found to be among the most important. Secondarily, Altruism, Imitative Behavior and Imparting Information are found. Of lesser importance are Corrective Recapitulation of the Primary Family Group, Catharsis, Hope and Existential Factors. The relative importance of different Helping Factors could be attributable to the educational nature of the group and the absence of problems experienced by the participants. The results equally indicate that the fact of being in nature, of carrying out activities that require personal coping strategies and experimenting with challenge and success through risk-taking have a catalytic effect on the occurrence of Helping Factors. These results resonate with elements that are already recognized in programs implemented in the context of natural outdoor and adventure settings, such as experimenting with challenge and success through risk-taking, adaptive dissonance and the relationships between stakeholders and members of the group (McKenzie, 2003; Panicucci, 2007; Priest, 1999a; Russell & Phillips-Miller, 2002). The choice of Helping Factors as an analytical framework brings new light to the central position that the group occupies in interventions in natural outdoor and adventure settings. In this sense, the results of this thesis are breaking new ground. Within the literature, few links have been made between Helping Factors and interventions in natural outdoor and adventure settings (Gass et al., 2012; Williams, 2000). Furthermore, studies on Helping Factors have been predominantly carried out in traditional intervention environments and with clinical and adult populations (Shechtman, 2003; Shechtman, Bar-el, & Hadar, 1997; Yalom & Leszcz, 2005), whereas this doctoral study focuses on young adults in natural outdoor and adventure settings. This thesis demonstrates that Helping Factors can occur within different conditions, pointing to possible future avenues of research in social work.
