The present study sought to extend goal-setting research by examining the nature of individuals' self-regulation with respect to performance goals while pursuing multiple, simultaneous goals. It was proposed that goal revision and effort allocation would be influenced by goal-performance discrepancies (GPD), causal attributions for factors affecting performance, self-efficacy, and rate of progress toward task goals. Results indicated that GPDs predicted goal revision direction and magnitude, and that controllability attributions moderated the GPD – revision relation. GPD size determined prioritization between tasks, as did self-efficacy. Mixed results were found for self-efficacy moderating the relation between GPD size and task prioritization. Rate of progress toward a task goal generally predicted prioritization between tasks and the amount of exerted effort within a single task. Although many results were not in the anticipated form, they still fit with modern theoretical frameworks associated with work motivation. Implications and suggestions for future research are discussed. / Master of Science

The transnational traffic of narcotics has had undeniable impacts on international development, for instance, stagnant economic growth in Myanmar (Chin, 2009), unsustainable agricultural practices in Yemen (Robins, 2016), and human security threats in Columbia (Thoumi, 2013). Furthermore, globalization is a catalyst for the transnational narcotics traffic (Robins, 2016; Aas, 2007; Kelly, Maghan & Serio, 2005). Several qualitative studies exist on the transnational narcotics traffic, yet few quantitative studies examine the issue. There is thus an opportunity for novel quantitative studies on the general question: “what are the main economic factors that influence the transnational traffic of narcotics between countries?” This study looked at the specific question: “are distance and economic size correlated with the volume of narcotics traffic between countries?” This study chose the gravity model as it centres on bilateral trade (Tinbergen, 1962), accounts for trade barriers (Kalirajan, 2008) and is empirically robust (Anderson 2011). This study defined a basic functional gravity model relating a proxy of the narcotics traffic to distance and economic size. Four augmented functional gravity models were also advanced to address omitted variable bias. The research was limited conceptually to cross sectional and pooled time series data. In addition, the data was also limited practically to a convenience sample of secondary data drawn from: the United Nations Office on Drugs and Crime’s (UNODC) (2016a) Individual Drug Seizures (IDS); the World Bank’s (2016) World Development Indicators; and the CEPII’s GeoDist (2016) datasets. This study used a novel “dosage” approach to unit standardization to overcome the challenge posed by the many measures and forms of narcotics. The study used the Poisson pseudo maximum likelihood (PPML) estimator as its estimations of the gravity model are consistent (Gourieroux et al., 1984), allow heteroscedasticity (Silva & Tenreyro, 2006) and avoid back transformation bias (Cox et al., 2008). The evidence analyzed in this study seem to indicate that the gravity model may not be applicable in its current form to the transnational narcotics traffic among countries that report drug seizures to the UNODC. However, the sampling method and the choice of proxy are likely to influence these findings. Moreover, the low explanatory power of the gravity model for the narcotics traffic, reflected in the values of the pseudo-R-squared coefficient of determination, indicates that other factors are at play. For instance, authors such as Asad and Harris (2003) and Thoumi (2003) argue that institutions could be a key factor in the narcotics traffic. Future empirical research into this topic could build on the theses findings to introduce new proxies and to explore alternate theoretical frameworks.

La violence contre les policiers a des répercussions importantes à la fois chez les policiers et pour les administrateurs de la police. En 2005, le taux canadien de voies de fait contre la police a atteint son plus haut sommet en plusieurs décennies, faisant état d’une situation préoccupante. Plusieurs provinces canadiennes connaissent d’ailleurs une hausse marquée de la violence contre leurs policiers depuis plusieurs années. Cette étude vise donc à examiner et à comprendre l’évolution du phénomène de violence contre les policiers au Canada par l’identification de facteurs qui pourraient expliquer les variations du taux de voies de fait contre les policiers. La méthode d’analyse privilégiée dans le cadre de cette étude est une analyse transversale de séries chronologiques regroupées (pooled time series) qui traite des données portant sur les dix provinces canadiennes pour une période allant de 1986 à 2006. Les résultats indiquent que plusieurs facteurs ont un impact sur la violence dont sont victimes les policiers : la proportion de la population âgée entre 15 et 24 ans, la proportion d’hommes de 15 ans et plus, la proportion de la population vivant dans une région urbaine, la proportion de gens divorcés, les taux résiduels de crimes de violence et de crimes rattachés aux drogues, et le nombre d’évasions et de personnes en liberté sans excuse. La présence croissante de policières, qui fait encore l’objet de débats, semble quant à elle réduire le nombre de voies de fait contre la police, quoique l’impact de ce facteur soit de faible portée. Au Québec, la une hausse importante du taux de voies de fait contre les policiers pourrait s’expliquer par la hausse de plusieurs facteurs identifiés comme jouant un rôle dans le phénomène, bien qu’il ne faille pas écarter qu’un changement dans la reportabilité puisse entrer en ligne de compte. / Violence against police officers has important implications both for police officers and police administration. In 2005, the Canadian rate of assault against police officers rose to its highest in decades, showing a worrying situation. Moreover, several Canadian provinces are experiencing a marked increase in violence against their police officers for several years. This study aims to examine and understand the trend of violence against the police officers in Canada by identifying factors affecting the rate of assaults against police officers. In order to do so, a pooled time series analysis, which processes data on the ten Canadian provinces for the period from 1986 to 2006, was performed. Findings indicate that several factors have an impact on the violence against the police: the proportion of young people aged 15-24, the proportion of males aged 15 and more, the proportion of population living in urban areas, the proportion of divorced people, the residual rates of violent crimes and drug crimes, and the number of people who escaped custody and prisoners unlawfully at large. The growing presence of women police officers, which is still debated, appears to reduce the number of assaults against police officers, although the impact of this factor is of limited scope. In Quebec, the continual increase in the rate of assaults against the police officers can possibly be explained by the increase of several factors identified as playing a role in the phenomenon, although a change in crime reporting can also be taken into account.
