The effect of viticultural and oenological treatments on fruit and wine composition of Chardonnay musque Study I: Effect ofveraison leafremoval and cluster thinning A one-year study was performed analysing die effects of leaf removal, cluster thinning, yeast strain selection, and enzyme usage on the chemical composition and sensory properties of Chardonnay musque wine. A number of substantial differences were found between treatments in °Brix, TA, pH, and in free and potentially volatile terpene concentrations. Greatest variations in sensory attributes were created however through use of different viticultural practices.Study II: Effect ofcluster thinning timing A two year study was conducted investigating the effect of cluster thinning timing, yeast strain selection, and enzyme usage on the chemical composition and sensory attributes of Chardonnay musque wine. Time of thinning was found to impact °BrLx, titratable acidit}% pH, and free and potentially volatile terpene concentrations, as well as, a number of yield parameters.Yeast strain selection and enzyme usage also impacted wine composition, andwas found to exhibit a greater effect on sensory properties than application of cluster thinning.

Both learning and basic biological mechanisms have been shown to play a role in the control of protein int^e. It has previously been shown that rats can adapt their dietary selection patterns successfully in the face of changing macronutrient requirements and availability. In particular, it has been demonstrated that when access to dietary protein is restricted for a period of time, rats selectively increase their consumption of a proteincontaining diet when it becomes available. Furthermore, it has been shown that animals are able to associate various orosensory cues with a food's nutrient content. In addition to the role that learning plays in food intake, there are also various biological mechanisms that have been shown to be involved in the control of feeding behaviour. Numerous studies have documented that various hormones and neurotransmitter substances mediate food intake. One such hormone is growth hormone-releasing factor (GRF), a peptide that induces the release of growth hormone (GH) from the anterior pituitary gland. Recent research by Vaccarino and Dickson ( 1 994) suggests that GRF may stimulate food intake by acting as a neurotransmitter in the suprachiasmatic nucleus (SCN) and the adjacent medial preoptic area (MPOA). In particular, when GRF is injected directly into the SCN/MPOA, it has been shown to selectively enhance the intake of protein in both fooddeprived and sated rats. Thus, GRF may play a role in activating protein consumption generally, and when animals have a need for protein, GRF may serve to trigger proteinseeking behaviour. Although researchers have separately examined the role of learning and the central mechanisms involved in the control of protein selection, no one has yet attempted to bring together these two lines of study. Thus, the purpose of this study is to join these two parallel lines of research in order to further our understanding of mechanisms controlling protein selection. In order to ascertain the combined effects that GRF and learning have on protein intake several hypothesis were examined. One major hypothesis was that rats would successfully alter their dietary selection patterns in response to protein restriction. It was speculated that rats kept on a nutritionally complete maintenance diet (NCMD) would consume equal amount of the intermittently presented high protein conditioning diet (HPCD) and protein-free conditioning diet (PFCD). However, it was hypothesized that rats kept on a protein-free maintenance diet (PFMD) would selectively increase their intake of the HPCD. Another hypothesis was that rats would learn to associate a distinct marker flavour with the nutritional content of the diets. If an animal is able to make the association between a marker flavour and the nutrient content of the food, then it is hypothesized that they will consume more of a mixed diet (equal portion HPCD and PFCD) with the marker flavour that was previously paired with the HPCD (Mixednp-f) when kept on the PFMD. In addition, it was hypothesized that intracranial injection of GRF into the SCN/MPOA would result in a selective increase in HPCD as well as Mixednp-t consumption. Results demonstrated that rats did in fact selectively increase their consumption of the flavoured HPCD and Mixednp-f when kept on the NCMD. These findings indicate that the rats successfully learned about the nutrient content of the conditioning diets and were able to associate a distinct marker flavour with the nutrient content of the diets. However, the results failed to support previous findings that GRF increases protein intake. In contrast, the administration of GRF significantly reduced consumption of HPCD during the first hour of testing as compared to the no injection condition. In addition, no differences in the intake of the HPCD were found between the GRF and vehicle condition. Because GRF did not selectively increase HPCD consumption, it was not surprising that GRF also did not increase MixedHP-rintake. What was interesting was that administration of GRF and vehicle did not reduc^Mixednp-f consumption as it had decreased HPCD consumption.

Objectives: The primary objective ofthis study was to explore motivation and psychological need salience in the initiatory and maintenance experiences of older female exercIsers. Methods: Female initiates (n = 3) and reflective maintainers (n = 3) 65 years of age or older (M = 76 years; SD = 5.37) participated in semi-structured interviews. Data were analyzed holistically and categorically, following a hermeneutic approach to inquiry. Results: Perceived importance of exercise benefits appeared to be the strongest motive for initiates at this stage of life and connections to others were perceived as valued, but less important in exercise contexts. Also, listening to one's body over instructions from the exercise leader emerged as a key factor to success. Conclusions: Overall, the results ofthis study implicate more self-determined than controlled motives as sources of regulation in older females' exercise initiation experiences. Evidence for psychological needs was more heterogeneous and less conclusive.

Background: The purpose of this study was to examine the relationships between physical activity and healthy eating behaviour with the participant's motives and goals for each health behaviour. Methods: Participants (N 121; 93.2% female) enrolled in commercial weightloss programs at the time of data collection, completed self-reported instruments using a web-based interface that were in accordance with Deci and Ryan's (2002) Self-Determination Theory (SDT). Results: Multiple linear regression models revealed that motivation and goals collectively accounted for between 0.21 to 0.29 percent and 0.03 to 0.16 percent of the variance in physical and healthy eating behaviours in this sample. In general, goals regarding either behaviour did not appear to have strong predictive relationships with each health behaviour beyond the contributions of motives. Discussion: Overall, findings from this study suggest that motives seem to mattermore than goals for both physical activity and healthy eating behaviour in clientele of commercial weight-loss programs. Therefore commercial weight-loss program implementers may want to consider placing more attention on motives I than goals for their clientele when designing weight-loss and weight-maintenance initiatives.

The purposes of this study were: a) to examine the role of personality and selfregulation in the gambling behaviour participation of late adolescents and emerging adults. In particular, the present study examined i f certain personality traits were more prevalent in high-risk gamblers than in young people considered low or at-risk gamblers; and, b) to examine i f the ability to self-regulate helped distinguish differences among the three groups of gamblers (low-risk, at-risk, and high-risk gamblers). A sample of late adolescents and emerging adults (N = 100) attending Brock University, completed a survey that assessed current gambling behaviour (both frequency and consequence experience), personality, self-esteem, and self-regulation. It was found that high-risk gamblers had lower scores on the personality dimensions Emotionality, Conscientiousness (especially on its Prudence facet), and Honesty-Humility (especially on its Fairness, Greed Avoidance, and Modesty facets) than at-risk or low-risk gamblers and higher scores on impulsive sensation seeking and impulsivity than at-risk or low-risk gamblers. Similarly, high-risk gamblers reported lower levels of self-regulation than both at-risk and low-risk gamblers. The findings from this study support past research which suggests that young people who gamble at problematic levels differ on many personality traits and often have more difficulty self-regulating than young people who do not participate at problematic levels. Findings may aid in the development of intervention and prevention programs that utilize specific self-regulation techniques with a young gambling population.

This thesis considers that the purport of the Bhagavadgita is to prioritize the philosophy of loving devotion to God (bhakti), not the propagation of color-coded-caste (varna system). The distinction between bhakti and caste becomes clear when one sees their effect on human life and on the society. Jnana and karma, two of the other polarities with which the Gita contends, finally support bhakti towards betterment, not deterioration, if done selflessly and with balance. Caste, however, is a totally different tension, which is always detrimental to the well-being of the person and the society. In the Gita, the devotees' mystical or emotional love of, God apprehends their ~ oneness with the Supreme God and with all beings, and transcends the pitiless segregation of the caste system, and opens the path of salvation to all irrespective of race, color, caste, class or gender in life. In spite of much opposition from orthodoxy, the bhakti movement spread allover India, and bhakti itself rose to the level of orthodoxy and has become the faith of millions of people especially of the south, and surprisingly, of even of those of the so called highest caste. And yet, caste still remains as an indelible mark of every Hindu, even after they change their religion. Although caste is less venomous now, it is still openly present in all walks of Indian life and shows up its ugly head at important moments such as marriage, elections for public office, admission to school or employment. True, bhakti is the antidote for. caste; but only real bhakti can remove caste completely, not mere lip-service to it. This thesis claims that bhakti is the deliberate major thrust of the teaching of the Gita while caste seems to be a contradiction of this thrust.
