A DYNAMIC FRAMEWORK FOR THE RELATIONS BETWEEN FOREIGN EXCHANGE RATES, SAVINGS AND INVESTMENTS

The Meese-Rogoff forecasting puzzle states that foreign exchange (FX) rates are unpredictable. Since one country’s macroeconomic conditions could affect the price of its national currency, we study the dynamic relations between the FX rates and some macroeconomic accounts. Our research tests whether the predictability of the FX rates could be improved through the advanced econometrics. Improving the predictability of the FX rates has important implications for various groups including investors, business entities and the government. The present thesis examines the dynamic relations between the FX rates, savings and investments for a sample of 25 countries from the Organization for Economic Cooperation and Development. We apply quarterly data of FX rates, macroeconomic indices and accounts including the savings and the investments over three decades. Through preliminary Augmented Dickey-Fuller unit root tests and Johansen cointegration tests, we found that the savings rate and the investment rate are cointegrated with the vector (1,-1). This result is consistent with many previous studies on the savings-investment relations and therefore confirms the validity of the Feldstein-Horioka puzzle. Because of the special cointegrating relation between the savings rate and investment rate, we introduce the savings-investment rate differential (SID). Investigating each country through a vector autoregression (VAR) model, we observe extremely insignificant coefficient estimates of the historical SIDs upon the present FX rates. We also report similar findings through the panel VAR approach. We thus conclude that the historical SIDs are useless in forecasting the FX rate. Nonetheless, the coefficients of the past FX rates upon the current SIDs for both the country-specific and the panel VAR models are statistically significant. Therefore, we conclude that the historical FX rates can conversely predict the SID to some degree. Specifically, depreciation in the domestic currency would cause the increase in the SID.

Dispositional Forgiveness and Health in Romantic Relationships: An Exploration of Sex Differences, Actor Effects, and Partner Effects

The individual and dyadic associations between dispositional forgiveness of self, others, and situations and mental and physical health in individuals involved in romantic relationships were examined. Sex differences in the relationship between dispositional forgiveness and health were examined. Sex differences in the dyadic relationship between forgiveness and health were also examined. The dispositional forgiveness scores of 297 partners involved in a romantic relationship were used to predict their own as well as their partners' physical and mental health. Both members of the relationship separately completed an Internet-based questionnaire assessing personality traits, relationship variables, and physical and mental health. The couple was provided with monetary compensation. Analyses revealed that women's dispositional forgiveness of self, others, and situations were positively associated with their own physical and mental health. Similarly, men's dispositional forgiveness of self, others, and situations were positively associated with their own mental and physical health. At the individual level, there were no sex differences in the relationship between dispositional forgiveness and health, nor were there sex differences in men and women's reports of dispositional forgiveness. Analyses revealed that men's forgiveness of others and situations were positively associated with their female partners' mental health. There were no partner effects for women or for physical health. The implications of these results for research in the forgiveness-health literature and research on forgiveness in romantic relationships were discussed as were directions for future research.

The Relationship Between Youth Risk-Taking Behaviour and Activity Engagement

Youth have been found to engage in various risk-taking behaviours at higher rates than any other age group. However, there is a lack of research on the division between adaptive and maladaptive risk behaviours among adolescents and emerging adults. Adaptive risk-taking behaviours may present youth with ways to successfully partake in the risk behaviours that they are naturally inclined to engage in. The relationship between activity engagement and positive youth development has been extensively studied and cited as a way to expose youth to positive experiences and promote successful development. However, the relationship between activity engagement and risk behaviours among youth has yetto be studied in depth. This study investigated the potential relationship between various adaptive and maladaptive risk behaviours and activity engagement among youth, through an indirect link through five mediator variables. These potential mediators represented the three systems in Jessor's Problem Behaviour Theory. Participants included 276 youth (M = 19.06 years, SD = 1.60, 89.1 % female) from Brock University. Results revealed that activity engagement significantly predicted greater adaptive social risk behaviours among youth. However, there was no mediating effect through the problem behaviour systems. Correlations revealed that being male was associated with more maladaptive risk behaviours and fewer adaptive risk behaviours than females. Additionally, behavioural engagement specifically related to less maladaptive physical health risks and psychological engagement related to greater adaptive social risks. Overall, these findings suggest that activity engagement may be differentially related to the various types of risk-taking and gender associations may exist between the various types and dimensions of risk behaviours, but future work is needed to understand the variables that may explain such relationships.

Socio-demographic factors, smoking, symptoms, morbidities and pulmonary function and quality of life in individuals with a heavy smoking history

Objective: To determine which socio-demographic, exposure, morbidity and symptom variables are associated with health-related quality of life among former and current heavy smokers. Methods: Cross sectional data from 2537 participants were studied. All participants were at ≥2% risk of developing lung cancer within 6 years. Linear and logistic regression models utilizing a multivariable fractional polynomial selection process identified variables associated with health-related quality of life, measured by the EQ-5D. Results: Upstream and downstream associations between smoking cessation and higher health-related quality of life were evident. Significant upstream associations, such as education level and current working status and were explained by the addition of morbidities and symptoms to regression models. Having arthritis, decreased forced expiratory volume in one second, fatigue, poor appetite or dyspnea were most highly and commonly associated with decreased HRQoL. Discussion: Upstream factors such as educational attainment, employment status and smoking cessation should be targeted to prevent decreased health-related quality of life. Practitioners should focus treatment on downstream factors, especially symptoms, to improve health-related quality of life.

Cryptic species status of Anopheles (Diptera: Culicidae) mosquitoes in Canada using a multidisciplinary approach

Many species of Anopheles mosquitoes (Diptera: Culicidae) are now recognized as species complexes whose members are often indistinguishable morphologically but identifiable based on ecological, genetic, or behavioural data. Because the members of species complexes often differ in their vector potential, accurate identification of vector species is essential for successful mosquito control. To investigate the cryptic species status of Anopheles mosquitoes in Canada, specimens were collected from across the country and examined using morphological, molecular, and ecological data. Six of the seven traditionally recognised species from Canada were collected from locations in British Columbia, Quebec, Newfoundland and Labrador, and throughout Ontario, including Anopheles barberi, An. earlei, An. freeborni, An. punctipennis, An. quadrimaculatus s.l., and An. walkeri. Variation in polymorphic traits within An. earlei, An. punctipennis, and An. quadrimaculatus s.l. were quantified and egg morphology examined using scanning electron microscopy. Morphological identification of adult and larval specimens suggested that two described cryptic species, An. perplexens and An. smaragdinus, were present in Canada. DNA sequence data were analysed for evidence of cryptic species using three molecular markers: COl, ITS2, and ITS!. Intraspecific COl variation was very low in most species «1 %), except for An. punctipennis with 2% sequence divergence between those from British Columbia (BC) and Ontario (ON), and An. walkeri with 7% sequence divergence between populations from Manitoulin Island (NO) and Long Point Provincial Park (LP). Similar patterns were also seen using ITS2 and ITS 1. Therefore, molecular data revealed the presence of two putative cryptic species within two species examined (i.e., An. walkeri and An. punctipennis), corresponding to collection location (i.e., NO vs. LP and BC vs. ON, respectively). Surprisingly, there was no molecular support for the presence of either An. perplexens or An. smaragdinus in Canada despite the morphological assessments. Ecological data from all collection sites were recorded and are available in an online database designed to manage all collection and identification data. Current bionomic information, including regional abundance, larval habitat, and species associations, was determined for each species. This multidisciplinary study of Anopheles mosquitoes is the first detailed investigation of these potential disease vectors in Canada and demonstrates the importance of an integrated approach to anopheline systematics that includes molecular data.
