The purpose of this study was to develop and evaluate an assessment that measured savouring leisure. The assessment items developed were reviewed for content validity by eight international therapeutic recreation (TR) educators and administrators as well as eleven TR practitioners. An exploratory factor analysis was conducted to determine the most suitable items for the assessment. The results suggest that the original three subscale design needed to be modified to five. The reliability of the total assessment is α=.84. Statistical analysis for construct validity reveal 58.52% of the variance explained, and a moderate correlation was found between this study and other savouring assessments. The implications of the shift in conceptualization are reviewed through discussing factor analysis issues, the lived experience of savouring leisure, and the impact of the content validity process. This study contributes to the ongoing dialog of savouring leisure. Recommendations for future research are discussed.

In this thesis we study the properties of two large dynamic networks, the competition network of advertisers on the Google and Bing search engines and the dynamic network of friend relationships among avatars in the massively multiplayer online game (MMOG) Planetside 2. We are particularly interested in removal patterns in these networks. Our main finding is that in both of these networks the nodes which are most commonly removed are minor near isolated nodes. We also investigate the process of merging of two large networks using data captured during the merger of servers of Planetside 2. We found that the original network structures do not really merge but rather they get gradually replaced by newcomers not associated with the original structures. In the final part of the thesis we investigate the concept of motifs in the Barabási-Albert random graph. We establish some bounds on the number of motifs in this graph.

Many real-world optimization problems contain multiple (often conflicting) goals to be optimized concurrently, commonly referred to as multi-objective problems (MOPs). Over the past few decades, a plethora of multi-objective algorithms have been proposed, often tested on MOPs possessing two or three objectives. Unfortunately, when tasked with solving MOPs with four or more objectives, referred to as many-objective problems (MaOPs), a large majority of optimizers experience significant performance degradation. The downfall of these optimizers is that simultaneously maintaining a well-spread set of solutions along with appropriate selection pressure to converge becomes difficult as the number of objectives increase. This difficulty is further compounded for large-scale MaOPs, i.e., MaOPs possessing large amounts of decision variables. In this thesis, we explore the challenges of many-objective optimization and propose three new promising algorithms designed to efficiently solve MaOPs. Experimental results demonstrate the proposed optimizers to perform very well, often outperforming state-of-the-art many-objective algorithms.

Un diagnostic de cancer du sein met la relation d’un couple à l'épreuve. La communication à propos du cancer peut aider les conjoints à s’appuyer mutuellement afin de mieux s’adapter à la maladie. Cependant, dans la documentation existante, peu d’échelles mesurent explicitement cette forme de communication. Ce projet avait pour but de valider l’échelle de communication des couples aux prises avec le cancer (CCC). Les patientes (N = 120) et leurs conjoints (N = 109) ont été interrogés au sujet de leur expérience avec le cancer du sein. Une analyse factorielle performé sur l’ensemble des données a permis de retenir deux facteurs pour l’échelle CCC, l’évitement et l’ouverture à la communication. L’échelle a démontré une bonne validité convergente avec le Primary Communication Inventory (r = .54, p <.01 patientes; r = .55, p <.01 partenaires). Finalement, l’échelle CCC prédit la dépression (Δr² = 0.029) et l’ajustement marital (Δr² = 0.032) au-delà de la communication générale. Avec plus ample développement, l'échelle actuelle pourrait servir à des fins de recherche ainsi que dans des contextes cliniques où une évaluation après un diagnostic de cancer permettrait, au besoin, la mise en oeuvre précoce d’interventions sur la communication conjugale au propos de la maladie.
