This thesis provides an ethnographic account of the journey from diagnosis with a life-limiting illness to the end of life. It tracks the lives and eventual deaths of eight people and 83 family members for a period of three and a half years in total. Culture is located as a central element or lens by which to view this journey. The role, function and issues for social work as a profession are discussed in various chapters. The theoretical underpinnings of the thesis are informed by the ecological perspective combined with psychosocial theories of loss and grief. Drawing on a broad social systems theory, in conjunction with an ethnographic methodology and grounded theory analysis, contributes to the development of research which firmly takes culture into account. Four primary topic areas are presented: a narrative exploration of diagnosis, the changing landscape that participants encounter, the embodiment of new places and spaces, and finally, the journey’s end. The themes from the four topic areas contribute to the development of the two core categories “time and place” and “preparedness for death”. A schematic representation of the paths participants took is provided in the discussion of the core categories. Lastly, the New Zealand Palliative Care Strategy (Ministry of Health, 2001) is drawn on to aid the discussion of issues arising from the research and the implications for practice in this field.

L'objectif de cette thèse composée de six articles théoriques et empiriques, est d'identifier les moyens les plus efficaces d'encourager les usagers de drogues – légales et illégales – à adopter des habitudes plus saines en réduisant leur consommation. La première étape consiste à évaluer l’ampleur du problème en mesurant le coût social des drogues (tabac, alcool et drogues illicites) en France en 2010. Malgré les campagnes de prévention massives, la proportion inquiétante des consommateurs de substances nocives, mais surtout, la part élevée de personnes déclarant regretter d'avoir commencé leur consommation, conduisent à reconsidérer le paradigme traditionnel de l’addiction rationnelle, à la base de la plupart des travaux de recherche sur les addictions en économie. Au contraire, admettre une polyphasie cognitive chez les individus avec d’une part, un planner prenant ses décisions aussi rationnellement que ses capacités cognitives ne le lui permettent, et un doer ne cherchant qu’à atteindre une satisfaction immédiate, permet de construire un cadre théorique original tenant compte des émotions de court terme et de long terme des agents, ainsi que le rôle des normes sociales sur leurs décisions de consommation addictives. Le modèle construit à partir de ce cadre, ainsi que son analyse sur un panel de fumeurs français, permet de proposer des politiques novatrices visant à renforcer la motivation des individus à arrêter leur consommation addictive en réduisant leurs problèmes d’autocontrôle, en agissant sur leur perception des dangers liés à l’usage de drogues, et en ciblant un changement normatif de leur consommation. La plupart de ces recommandations ne sont pas applicables aux drogues illégales en raison de leur statut juridique. De ce fait, le seul levier permettant de définir une stratégie visant à réduire les coûts induits, est l’étude des alternatives juridiques à la pénalisation de la consommation, en particulier en ce qui concerne le cannabis, qui est la drogue illicite la plus largement utilisée en France, mais également dans la plupart des pays développés. / The objective of this thesis, composed of six academic papers, is to identify how to encourage people to adopt healthier habits by reducing their ⎯ legal and illegal ⎯ drug consumption. The first step is to evaluate the importance of the problem by measuring the social costs of drugs (tobacco, alcohol, and illegal drugs) in France in 2010. Despite massive prevention campaigns, the worrying proportion of harmful substance users and the high proportion of individuals who declare they regret having started consumption leads to reconsideration of the traditional paradigm of rational addiction and its extensions at the basis of most research works on addiction in economics. In contrast, admitting that individuals exhibit a dual process of reasoning, with a planner acting as rationally as the individual’s cognitive capabilities permit on the one hand and a doer who only seeks short-term rewards on the other, allows the construction of an original theoretical framework that takes into account consumers’ short-term and long-term emotions, and the role of social norms in addictive consumption. The model built from this framework and its testing through an analysis of smokers permit the proposal of innovative policies aiming to enhance individuals’ motivation to quit addictive consumption by (i) reducing their self-control problems, (ii) acting on their perception of the danger of the drug, and (iii) by targeting a normative change. Most of these recommendations are not applicable to illegal drugs due to their legal status. Thus, the strategy to reduce harm in this instance is to study the legal alternatives to the criminalization of use, especially for cannabis, which is the most widely used illegal drug in France, as it also is in most developed countries.

Although many studies discuss the negative impact of it, few of them emphasize the relationship between cognitive impulsiveness and decision making in non-clinical subjects. The aim of this study is to investigate the effects of cognitive impulsiveness on decision making and explore the strategies used by participants to solve problems. For this purpose, we apply two measures of impulsivity: the self-report Barratt Impulsiveness Scale (BIS-11) and the performance based Cognitive Reflection Test (CRT).This is the first study that compares self-report impulsiveness based on BIS-11 and performance-based reflectivity measured by CRT. Moreover, due to the fact that we apply the instruments on pen and paper, it is possible to evaluate participants’ reasoning processes employed to answer CRT questions. These reasoning processes are related to the role of Executive Functions for decision making and its relationship with impulsiveness. In practical terms, we observed participants’ strategies by analyzing their calculation expressions and data organization to answer CRT questions in the paper sheet. The sample consists of 191 non-clinical adults, professionals, and undergraduate students from the fields of business, management, and accounting. Results show that cognitive impulsiveness may negatively affect performance. Moreover, there is no difference in strategies used by impulsive and non-impulsive people during a decision making, and who calculate in the paper sheet perform better. Finally, people who inhibit their immediate answers also perform better during a decision making.

This is a review of what the currently dominant theories of moral decision-making are and where they derive from. While the introduction serves as a common ground to explain what moral decision-making is, the earlier parts of the thesis describe older traditionalist theories within the field,  theories of emotional decision-making, in the form of the somatic marker hypothesis, as well as critique of the older traditionalist theories through the social intuitionist model. Both of these two theories are explained as the foundation of the current theories of moral decision-making and after establishing a clear basis on what the currently dominant theories of moral decision-making are built on, said theories are introduced in the form of the dual-processing theory and the event-feature-emotion complexes which are thoroughly reviewed, explained in detail and serves as the core of the text. This is afterward followed by criticism as well as arguments in favor of both theories as well as criticisms from other researchers who disagree with the methodology which the theories of moral decision-making are conducted on. The essay reviews the current state of the field of moral decision-making which has been split up into two different approaches, the locationist approach and the constructionist approach. The essay concludes that there are terms which needs to be clarified in order for the field to move forward and studies to be made regarding the social implications of gut reactions in moral decision-making.

Two studies were conducted to support the dual process model of moral decision making, which states that there are two pathways to moral decisions: one emotional and the other cognitive. Decisions made in personal dilemmas are driven by emotions and intuition, while decisions made in impersonal dilemmas are driven by cognitive factors. Intuitive, emotional reactions tend to lead to non-utilitarian decisions while deliberative reasoning tends to lead to utilitarian decisions. For the current studies, undergraduate students from the University of North Florida completed working memory tests, an empathy scale, and also responded to moral dilemma scenarios. In the second study, participants were asked to respond to the moral dilemma scenarios in the following conditions: baseline, working memory condition (counting task), cold water (cold pressor task), and warm water. In Study 1, participants in the high working memory group had slower reaction times while responding to self dilemmas. In Study 2, the empathy item “I feel other people’s joy” was the best predictor of participants’ utilitarian decisions. These results are framed in terms of the dual process model and possible directions for future research.

El enfoque experimental es el corazón de algunos de los desarrollos más interesantes de la economía. Básicamente, los experimentos se utilizan para generar datos controlados. El término "datos controlados" se refiere al hecho de que la mayoría de los factores en los que influyen las conductas se mantienen constantes, y solo un factor de interés (el "tratamiento'') cambia a la vez. Este es el punto crítico para hacer una inferencia causal. A veces, este proceso de generación ocurre de forma natural (es decir, un "experimento natural''). Sin embargo, la mayoría de las veces, el investigador es el encargado de desarrollar y controlar el proceso de generación. Todas las áreas de la ciencia (incluida la economía) deben considerar todas las metodologías que se pueden aplicar. La teoría, los experimentos de laboratorio, los experimentos de campo, los experimentos online, la neuroeconomía, la investigación observacional y social, las encuestas y más, contribuyen a nuestra comprensión del mundo. En el primer capítulo de a tesis, se presentan resultados experimentales sobre subastas. Se consideran dos tratamientos experimentales: si el comprador prefiere más la calidad a la dimensión del precio, o si este último importa más que la calidad. Los participantes se asignan al azar a uno de estos dos tratamientos y se emparejan en grupos de cinco. Juegan una subasta de períodos múltiples, donde la calidad es exógena asignada en cada ronda y los sujetos presentan una rebaja al precio base anunciado. Las pujas se transforman en puntuaciones que combinan la calidad exógena y la rebaja. El vendedor con la puntuación más alta gana la subasta. Los resultados sugieren que, cuando el peso de la rebaja es mayor, los participantes pujan más cerca del equilibrio. Sin embargo, la probabilidad de obtener un resultado eficiente es mayor cuando se pone más peso en la calidad. En el segundo capítulo analizo los resultados de un experimento en línea en el que los sujetos juegan cuatro versiones del juego Stag-Hunt. Hay tres tratamientos: línea de base, retraso de tiempo y retraso motivado. En el segundo, los sujetos deben esperar 40 segundos antes de elegir una decisión. En el tercero, deben esperar 40 segundos y escribir un texto para motivar sus decisiones. Al final del juego, los participantes informan sobre creencias, preferencias de riesgo y una medida de confianza. El resultado principal es que los sujetos optan por colaborar menos cuando deliberan más. La explicación es que este tratamiento ayuda a los sujetos a comprender que esta es la opción más segura. En el tercer capítulo, los autores estiman el impacto de un programa educativo basado en juegos destinado a promover el uso sostenible del agua. Esto se hizo en la ciudad de Lucca, con miles de alumnos de 2º a 4º de primaria. Los hallazgos indican que los estudiantes del grupo de tratamiento (participantes del programa) mostraron una mayor conciencia sobre el consumo de agua respecto a aquellos estudiantes que no participaron en el programa. Además, encuentran que el efecto positivo aún se observa después de seis meses, lo que sugiere que los programas educativos basados en juegos pueden ser un instrumento eficaz para promover comportamientos prosociales en el consumo de agua.

<p>The Theory of Applied Mind of Programming (TAMP) provides a new model for describing how programmers think and learn. Historically, many students have struggled when learning to program. Programming as a discipline lives in logic and reason, but theory and science tell us that people do not always think rationally. TAMP builds upon the groundbreaking work of dual process theory and classical educational theorists (Piaget, Vygotsky, and Bruner) to rethink our assumptions about cognition and learning. Theory guides educators and researchers to improve their practice, not just their work but also their thinking. TAMP provides new theoretical constructs for describing the mental activities of programming, the challenges in learning to program, as well as a guidebook for creating and recognizing the value of theory.</p> <p>This dissertation is highly nontraditional. It does not include a typical empirical study using a familiar research methodology to guide data collection and analysis. Instead, it leverages existing data, as accumulated over a half-century of computing education research and a century of research into cognition and learning. Since an applicable methodology of theory-building did not exist, this work also defines a new methodology for theory building. The methodology of this dissertation borrows notation from philosophy and methods from grounded theory to define a transparent and rigorous approach to creating applied theories. By revisiting past studies through the lens of new theoretical propositions, theorists can conceive, refine, and internally validate new constructs and propositions to revolutionize how we view technical education.</p> <p>The takeaway from this dissertation is a set of new theoretical constructs and promising research and pedagogical approaches. TAMP proposes an applied model of Jerome Bruner's mental representations that describe the knowledge and cognitive processes of an experienced programmer. TAMP highlights implicit learning and the role of intuition in decision making across many aspects of programming. This work includes numerous examples of how to apply TAMP and its supporting theories in re-imagining teaching and research to offer alternative explanations for previously puzzling findings on student learning. TAMP may challenge conventional beliefs about applied reasoning and the extent of traditional pedagogy, but it also offers insights on how to promote creative problem-solving in students. </p><br>

Antimicrobial resistance is a major global health challenge. It threatens the achievement of multiple SDGs with disproportionately negative consequences for LMICs. AMR is associated with the misuse of antibiotics, which is especially dominant in livestock farming. On-farm biosecurity has been identified as an effective way to prevent diseases. This requires a change in the daily behaviours of farmers. While the application of social-psychological models gained immense popularity in veterinary and agricultural research, these models lack predictive and explanatory character, leading to the so-called intention-action gap. The emerging field of behavioural sciences likely offers a better explanation of human behaviour, however, studies published often lack use of an explicit theoretical framework. Therefore, this exploratory study aims to address this gap by using Kahneman’s Dual-Process Theory as a theoretical framework for behaviour science studies. To this end, a qualitative study with 15 smallholder poultry farmers in rural Ghana was conducted. The findings suggested the presence of cognitive biases and heuristics that hinder farmers’ uptake of biosecurity measures, such as temporal discounting, social cues, cognitive overload, psychological inertia and habits. However, all factors must be considered, including knowledge gaps, as well as practical and economic constraints. It is clear from the study that farmers are not a homogenous group and that any promotion of biosecurity is destined to fail if they do not take farmers' psychological and contextual reality into consideration. Therefore, this thesis concludes that additional insights and hypotheses can be generated using behavioural science and that it offers a better and more holistic theoretical framework than currently used behavioural change models. Suggestions for further work include more empirical study in farmer decision-making related to on-farm biosecurity from a behavioural lens. Specifically, the use of quantitative and experimental methods to investigate and confirm the hypotheses that emerged from this study.

Les développements récents de la recherche en sciences cognitives ont établi que les individus détectent fréquemment qu'ils sont en train de commettre certaines erreurs de raisonnement, alors même qu'ils n'identifient pas, et peut-être ne peuvent pas identifier, la source de ces erreurs. Jusqu'à maintenant, ce programme de recherche a principalement visé à démontrer que même les individus aux raisonnements les plus biaisés faisaient preuve de tendances à la détection de conflits. Le présent travail s'appuie sur ces résultats et analyse trois domaines d'enquête connexes et encore inexplorés : (1) les sous-types de détection de conflits ; (2) les différences individuelles quant à la détection ; (3) le caractère de généralité ou de spécificité au domaine des sensibilités pour la détection de conflits. En identifiant des sous-types de détection de conflits de plus en plus spécifiques, ce projet a pour objectif d'examiner les corrélations entre, d'une part, certaines sensibilités pour la détection de conflits, et des prédicteurs cognitifs, d'autre part. Il s'agit, fondamentalement, d'un travail préparatoire en vue d'une analyse différentielle complète des sensibilités particulières de détection de conflits parmi les individus en train de raisonner. / Recent state of the art research into cognitive biases has revealed that individuals often detect that they are making certain reasoning errors even when they themselves do not, perhaps cannot, articulate the source of the error. Until now, this research has focused primarily on demonstrating the existence of conflict detection tendencies among even the most biased reasoners. This thesis builds on this research by analyzing three related and unexplored areas of inquiry: (1) subtypes of conflict detection; (2) individual-specific differences among detectors; and (3) the domain generality or specificity of conflict detection sensitivities. By identifying increasingly fine-tuned detection subtypes, the project aims to explore correlations between particular conflict detection sensitivities and other cognitive predictors. It is, essentially, preparatory work for a complete differential analysis of conflict detection sensitivities among reasoners.

Each year millions of people face the medical decision-making cycle that comes with a diagnosis of cancer. For patients and their families, this can be a rollercoaster of confusion and fear. Researchers have indicated that the complexity of the decision-making process is underrepresented in the current approach of informed decision-making. The purpose of this study was to add to scientifically-validated research expanding the identification of factors that influence decision-making for individuals diagnosed with cancer. Fuzzy trace theory (FTT) is the dual process memory theory used as the framework for this study. Qualitative data were collected using semistructured interviews with 10 participants. The sampling strategy included purposeful sampling and snowball or chain sampling. The audio-recorded interviews were transcribed and analyzed. Software tools were used to aid in the creation of word mapping and clusters and a naming structure emerged. A comprehensive thematic analysis was completed. Participants detailed experiences with family and social dynamics, psychological or emotional stress, external influencing factors to the decision-making process, and experiences with cancer advertising. This research can create positive social change through the advancement of scientifically-validated research to support patients during the decision-making process.
