Respiratory Sinus Arrhythmia and Emotional Responding to Dyadic Discussions of a Disagreement as Predictors of Helping Related Subjective Well-Being in Older Mothers and Their Adult Daughters

The current study considered affect-related variables as predictors of the quality of helping relationships between older mothers and their adult daughters. Specifically, self-reported and observed emotional responses to the dyadic discussion of a disagreement between mothers and daughters, as well as baseline measures of respiratory sinus arrhythmia were considered as predictors of mothers' and daughters' satisfaction with their helping relationships. Relationship satisfaction was measured by considering mothers' and daughters' subjective well-being specifically in regards to the help they gave and received. Overall, these variables predicted more variance in mothers' satisfaction with their helping relationships than daughters', and RSA (respiratory sinus arrhythmia) was a stronger predictor than the self-reported or observed emotional reactions to the dyadic discussion of a disagreement. Implications of these findings and limitations to the current study are discussed.

Unpacking Pieces of a Puzzle: Understanding Obesity-Related Health Risk through Lifestyle Behaviours and Well-Being

The primary objective of this non-experimental study was to examine the differences based on obesity-related health risk in terms of physical activity, sedentary behaviour and well-being in adults. Participants (N = 50; Mage = 38.50, SDage = 14.21) were asked to wear a SenseWear Armband (SWA) across a seven day monitoring period followed by a questionnaire package. Using the National Institute of Health’s (1998) criteria, participants were classified as either least, increased, or high risk based on waist circumference and Body Mass Index scores. Differences between these classifications were found in the amount of time spent in active energy expenditure for bouts of ten minutes or more (p = .002); specifically between least and high risk (p < .05). No other differences (p > .05) emerged. Participants’ also perceived the SWA as a practical and worthwhile device. Overall, these findings provide practical applications and future directions for health promotional research.

Two Levels of Motivation and Two Types of Well-Being: Relations Between General and Goal-Specific Motivations, and Eudaimonic and Hedonic Well-Being

In this thesis I assess the individual and joint predictive associations and effects between multiple motivation and well-being concepts. In particular, three pairs of motivation concepts (intrinsic/extrinsic, approach/avoidance, and eudaimonic/hedonic) are assessed simultaneously at two levels of analysis (disposition and goal) and examined in relation to two types of well-being (eudaimonic and hedonic) in two studies, one correlational and the other experimental. Study 1: Using a correlational design, participants (N = 325, M age = 19.10, 87% female) completed self-report measures assessing six motivation and two well-being concepts. Exploratory factor analyses were used to assess patterns of associations among the motivational constructs. Results indicated that constructs displaying conceptual and empirical similarities co-occur, particularly, intrinsic, approach and eudaimonic motivation. Regression models were used to assess predictive relations between the motivational constructs and well-being. Both types of well-being were predicted by approach and avoidance dispositions, and hedonic goals. Additionally, eudaimonic well-being was uniquely predicted by eudaimonic dispositions and goals, and intrinsic dispositions; and hedonic well-being was uniquely predicted by extrinsic dispositions and approach goals. The patterns of associations among motivational constructs, and similarities and differences in the ways they predict each type of well-being, are discussed. Study 2: Using an experimental design, participants (N = 447, M age = 19.30, 88% female) were randomly assigned to one of eight experimental conditions, each involving a manipulation aimed at priming combinations of the three pairs of motivational constructs at the goal level. Participants then completed measures of both types of well-being. ANOVAs were used to assess the main effects and interactions of experimental condition for each of the three pairs of motivational constructs on well-being. Main effects of experimental conditions were non-significant. However, results indicated that focus on each of the three pairs of motivational constructs predicted well-being and that the manipulation impacted well-being indirectly, through experimentally-shifted motivational focus. Few interactions emerged. Implications for future experimental research and the conceptual integration of motivation and well-being constructs are discussed. In conclusion, Studies 1 and 2 inform the motivation and well-being fields in novel ways and provide preliminary steps towards studying these fields from an integrated and comprehensive motivational framework.

Informing the structure of subjective well-being through examining changes in life satisfaction, positive affect, and negative affect

Subjective well-being (SWB) refers to how individuals evaluate and experience their lives in positive ways, and encompasses global judgments of life satisfaction (LS), as well as the frequency of positive and negative affect (PA and NA, respectively) in one’s life. To inform the current ambiguity concerning the structure of SWB, the aim of this Masters thesis was to evaluate the structure of SWB based on whether the three components of SWB change together or independently naturally, over time and following experimental manipulation. In Study 1, associations among changes in LS, PA, and NA were evaluated using a longitudinal approach tracking natural changes in the components over periods of three months and three years. Results indicated that change in one component was related to change in the other two components. In Study 2, an experimental design was used to manipulate each SWB component individually, and evaluate changes in all three components following each manipulation. Manipulation materials designed to target LS only were effective (i.e., led to heightened focus on LS, and not PA or NA) and created an increase in both LS and PA. Manipulation materials designed to target PA and NA only were not effective (i.e., led to heightened focus on the target component, as well as on LS). Furthermore, in both studies the strength of an individual’s SWB (assessed in terms of structural consistency and structural ambivalence in Study 1 and Study 2, along with subjective ambivalence in Study 2) did not consistently moderate the degree to which changes in the components were associated with one another. Together, these findings indicate that the structure of SWB may be complex and dynamic, rather than static. Alternatively, the components of SWB may not be easily manipulated in isolation of one another. Implications for existing structural models of SWB are discussed.

Mindfulness Practices and Children’s Emotional and Mental Well-Being: Activities to Build and Strengthen Everyday Resilience Adapted for Primary School Teachers

This project reviewed current research on mental health and Canadian children, and then examined the practice of mindfulness as a means of supporting well-being and circumventing the potential detrimental effects of mental health problems. By contextualizing these findings within the recently released educational vision of the Ontario Ministry of Education (2014), which identifies well-being as one of the core principles of education in Ontario, this project investigated how mindfulness-based practices can be brought into the primary grade classroom. The ultimate purpose of this project is the development of a handbook for Ontario teachers of students in grades 1 to 3 (ages 6 to 8). This resource was developed from a comprehensive literature review and provides educators with easy-to-follow activities to use in the classroom to encourage the development of resilience and emotional well-being through mindfulness. The handbook also includes additional information and resources regarding both mindfulness and mental health that may be helpful to teachers, students, and parents.

Student Perspectives of the Context of Recess; Implications for Student Well-Being

With most students in Canada spending approximately 180 days a year in school, averaging more than six hours a day (Morrison & Kirby, 2011), Wei, Szumilas and Kutcher (2011) argue that this places educational institutions in an unique position in terms of influencing the health and well-being of students. This brings forth the need for school environments to be utilized in ways that are conducive to promoting student development. Much of the educational and developmental components embedded within the school system as well as experiences within greatly influence student’s health and well-being. A national statement was made a concerning American children’s education and mental health that is greatly applicable to the Canadian school system. It was stated that schools “must be active partners in the mental health care of our children” because of the “important interplay between emotional health and school success” (Lazarus & Sulkowski, 2011, pp. 15-16). This identifies the need to ensure that all students, as much as possible, are being provided with safe environments and sufficient support in order to encourage positive developmental trajectories of student health and well-being.

Interpersonal Comparisons of Well-Being

This paper, which is to be published as a chapter in the Oxford Handbook of Political Economy, provides an introduction to social-choice theory with interpersonal comparisons of well-being. We argue that the most promising route of escape from the negative conclusion of Arrow’s theorem is to use a richer informational environment than ordinal measurability and the absence of interpersonal comparability of well-being. We discuss welfarist social evaluation (which requires that the levels of individual well-being in two alternatives are the only determinants of their social ranking) and present characterizations of some important social-evaluation orderings.

Well-Being Freedom and The Possibility of Public-Provision Unit in Global Context

The purpose of this paper is, first, to investigate the interconnections of substantive freedoms, which are indispensable for every individual to “lead the kind of lives they have reason to value” (Sen, 1999b, p.10,18), and which have legitimate and ethical reasons to be publicly secured, second, to investigate a conception of public-provision unit that embodies “the right to well-being freedom”, and a conception of decision-making unit that corresponds to it, based on the perspective of Sen’s capability theory and its extension, comparing with that of Rawls’ Theory of Justice and A Law of People. If we intend to construct such a public-provision unit, which conducts redistribution as a whole, and which receives every individual who cannot belong to any fixed local group, what kind of a body should we assume as a public-provision unit? And further, what kind of a body should we assume as a decision-making unit, which is responsible for deciding or revising the basic conceptions of public provision unit?

Moral Loopholes in the Global Economic Environment: Why Well-Intentioned Organizations Act in Harmful Ways

Thomas Pogge’s notion of moral loopholes serves to provide support for two claims: first, that the ethical code of the global economic order contains moral loopholes that allow participants in special social arrangements to reduce their obligations to those outside the social arrangement, which leads to morally objectionable actions for which no party feels responsible and that are also counterproductive to the overall objective of the economic system; and, second, that these moral loopholes are more likely to exist as our economic order becomes more global. Finally, it will be shown that attempts to rectify the situation with voluntary corporate codes of conduct are inadequate. The argument proceeds through analysis of one case study, concerning action by the executive of the Cerrejón mining operation at La Guajira Penisular, Colombia.

A detailed study of the lithiation of iron phosphate as well as the development of a novel synthesis of lithium iron silicate as cathode material for lithium-ion batteries

Dans cette thèse nous démontrons le travail fait sur deux matériaux de cathodes pour les piles lithium-ion. Dans la première partie, nous avons préparé du phosphate de fer lithié (LiFePO4) par deux méthodes de lithiation présentées dans la littérature qui utilisent du phosphate de fer (FePO4) amorphe comme précurseur. Pour les deux méthodes, le produit obtenu à chaque étape de la synthèse a été analysé par la spectroscopie Mössbauer ainsi que par diffraction des rayons X (DRX) pour mieux comprendre le mécanisme de la réaction. Les résultats de ces analyses ont été publiés dans Journal of Power Sources. Le deuxième matériau de cathode qui a été étudié est le silicate de fer lithié (Li2FeSiO4). Une nouvelle méthode de synthèse a été développée pour obtenir le silicate de fer lithié en utilisant des produits chimiques peu couteux ainsi que de l’équipement de laboratoire de base. Le matériau a été obtenu par une synthèse à l’état solide. Les performances électrochimiques ont été obtenues après une étape de broyage et un dépôt d’une couche de carbone. Un essai a été fait pour synthétiser une version substituée du silicate de fer lithié dans le but d’augmenter les performances électrochimiques de ce matériau.
