The current study investigated body image differences in post-menopausal women who self-reported having (SRO) or not having (SRN) osteoporosis and the impact of a 16-week exercise program on body image in these groups. Participants completed a measure of body image, and were randomly assigned to a 16-week exercise program or control group, stratified by self-reported osteoporosis status. After 16 weeks, they completed the same body image measure. There were no differences in body image between the two osteoporosis groups. The exercise intervention had a positive impact on body image for both the SRO and SRN groups. The exercise groups showed increases in fitness and health orientation and body areas satisfaction from baseline to 16-weeks, while the non-exercise group showed decreases in appearance and health evaluation, health orientation and body areas satisfaction. The results suggest an exercise program for post-menopausal women can lead to improvements in body image, regardless of osteoporosis status.

In Ontario 27% of young adults smoke, and annual surveillance data suggests tobacco use is plateauing after years of decline. The availability of inexpensive contraband tobacco products maybe contributing to this situation. Limited research has been conducted on the use of contraband tobacco and despite the increasing availability of contraband 'Native cigarettes', no studies to date have examined their use among young adults. Accordingly, this study examines: (a) what proportion of cigarette butts discarded on post-secondary campuses are contraband; and (b) whether the proportion of contraband butts varies between colleges and universities, across seven geographical regions in the province and based on proximity First Nations reserves. In March and April 2009, discarded cigarette butts were collected from the grounds of 25 post-secondary institutions across Ontario. At each school, cigarette butts were collected on a single day from four locations. The collected cigarette butts were reliably sorted into five categories according to their filtertip logos: legal, contraband First NationslNative cigarettes, international and suspected counterfeit cigarettes, unidentifiable and unknown. Contraband use was apparent on all campuses, but varied considerably from school to school. Data suggest that contraband Native cigarettes account for as little as 1 % to as much as 38 % of the total cigarette consumption at a particular school. The highest proportion of contraband was found on campuses in the Northern part of the province. Consumption of Native contraband was generally higher on colleges compared to universities. The presence of contraband tobacco on all campuses suggests that strategies to reduce smoking among young adults must respond to this cohort's use of these products.

The pyruvate dehydrogenase (PDH) complex regulates the oxidation of carbohydrates in mammals. Decreased activation of PDH following exhaustive exercise may aid the resynthesis of glycogen through increased activity of PDH kinase-4 (PDK4), one of four kinases that decrease the activity of the PDH complex. The purpose of this study was to examine the role of PDK4 in post-exercise glycogen resynthesis. Wild-type (WT) and PDK4-knockout (PDK4-KO mice) were exercised to exhaustion and were sampled at rest (Rest), at exercise exhaustion (Exh), and after two-hours post-exercise (Rec). Differences in feeding post-exercise led to the addition of a PDK4-KO group, pair-fed (PF) with WT mice. Glycogen fully recovered in all Rec groups in muscle however remained low in the PF group in liver. Flux through PDH was elevated in PDK4-KO muscle with feeding and low in the PF group in both tissues. This suggests PDK4 may fine-tune flux through PDH during exercise recovery.

Background. This study examined whether experiences of and relationships between depressive symptoms and substance use differs for first year college and university students. Methods. A proportionate stratified random sample of 6,100 university students and a census sample of 7,300 college students were invited to anonymously complete the National College Health Assessment. The final sample included 444 young adult first year university (n = 298) and college (n = 146) students. Results. More college than university students used tobacco (26.7; 11.1%) and marijuana (26.7%; 20.8%). Similar proportions consumed alcohol (75.3%; 76.5%). Almost all students reported past-year depressive symptoms. Mean number of symptoms was 5.43. Tobacco, alcohol and marijuana use were each positively associated with depression after adjusting for age and gender. Educational setting moderated the relationship between depression and tobacco use, and depression and marijuana use, with the relationship being stronger for university students. Implications. University campus health professionals especially, need to assess depression among students using substances and vice versa. Differences between college and university students require further attention.

Within the context of international adoption, previous research has focused on parentchild attachment relationships and various aspects of the adoption process. However, less is known about other aspects of parent-child relationships (e.g., cohesion, conflict) within internationally adoptive families. Additionally, there is a need for research that explores both parent and child perceptions of the process of adoption - including pre- and post-adoptive factors - and its connection to the quality of parent-child relationships. This research utilized a qualitatively-oriented methodology to conduct separate, in-depth interviews with 10 adoptive Canadian mothers and their adopted Chinese children (aged 9 to 11 years). Results highlight parent and child reports of mainly strong, positive relationships. Several pre-adoption experiences are examined, including institutionalization, age at the time of adoption, and parental stress/expectations. A key finding concerns the link that adoptive parents perceive between the quality of their child's pre-adoptive care (i.e., mainly early institutionalized care) and the quality of their relationship. Interestingly, this link is perceived in two different ways - either as a challenge for the parent-child relationship or as a means to strengthen it. Post-adoption experiences are also explored, including cultural socialization, creating a transracial family, discussing adoption, parental stress, and sibling involvement. A key finding involves parent and child reports that cultural socialization efforts (i.e., familiarizing children with Chinese culture) are linked to more positive parent-child relationships. The implications of these findings are discussed in relation to theory and practice within the context of international adoption.

ABC's popular television series Lost has been praised as one of the most innovative programs in the history of broadcast television primarily due to its unique storytelling content and structure. In this thesis, I argue that in spite of its unconventional stances in terms of narrative, genre, and character descriptions, Lost still conforms to the conventional understanding of family, fatherhood, and subjectivity by perpetuating the psychoanalytic myth of the Oedipus complex. The series emphasizes the centrality of the father in the lives of the survivors, and constructs character developments according to Freud's essentialist and phallocentric conception of subjectivity. In this way, it continues the classic psychoanalytic tradition that views the father as the essence of one's identity. In order to support this argument, I conduct a discursive reading of the show's two main characters: Jack Shepherd and John Locke. Through such a reading, I explore and unearth the mythic/psychoanalytic importance of the father in the psychology of these fictional constructs.

When working with under-served youth, possibly the most important, yet often times the most difficult, thing for practitioners to do is to build positive, trusting, open relationships. This study aims to address this challenge. Two groups of under-served youth were examined, one being teens deemed at-risk and one being youth with Autism Spectrum Disorder (ASD). This study was novel in its approach as all efforts were made to ensure the youth's opinions on how to be relational with them were heard. Two youths with ASD were nonverbal and a special picture interview procedure was developed to allow their participation. Three thematic statements emerged from the data collected: 1. Youth need low anxiety relationships. 2. Youth need novel forms of engagement. 3. Youth need us to understand that their actions reflect their histories. The analyses that lead to these statements are described as well as the reasoning and implications of these statements.

This study investigates the mediating impact of psychological capital and follower-leader relational capital on the relationship between ethical leadership and in-role performance through the lenses of social exchange theory, social information processing theory, and psychological resources theory. Analysis of data collected from a sample of 171 employees and 24 supervisors from Pakistan reveals that ethical leadership has a positive effect on followers in-role job performance, yet this effect is fully explained through the role of psychological capital and partially through follower-leader relational capital. Significant implications of these findings for further research and practice are discussed.

Across taxa, the early rearing environment contributes to adult morphological and physiological variation. For example, in birds, environmental temperature plays a key role in shaping bill size and clinal trends across latitudinal/thermal gradients. Such patterns support the role of the bill as a thermal window and in thermal balance. It remains unknown whether bill size and thermal function are reversibly plastic. We raised Japanese quail in warm (308C) or cold (158C) environments and then at a common intermediate temperature. We predicted that birds raised in cold temperatures would develop smaller bills than warm-reared individuals, and that regulation of blood flow to the bill in response to changing temperatures would parallel the bills role in thermal balance. Cold-reared birds developed shorter bills, although bill size exhibited catch-up growth once adults were placed at a common temperature. Despite having lived in a common thermal environment as adults, individuals that were initially reared in the warmth had higher bill surface temperatures than coldreared individuals, particularly under cold conditions. This suggests that blood vessel density and/or the control over blood flow in the bill retained a memory of early thermal ontogeny. We conclude that post-hatch temperature reversibly affects adult bill morphology but irreversibly influences the thermal physiological role of bills and may play an underappreciated role in avian energetics

Classical relational databases lack proper ways to manage certain real-world situations including imprecise or uncertain data. Fuzzy databases overcome this limitation by allowing each entry in the table to be a fuzzy set where each element of the corresponding domain is assigned a membership degree from the real interval [01]. But this fuzzy mechanism becomes inappropriate in modelling scenarios where data might be incomparable. Therefore, we become interested in further generalization of fuzzy database into L-fuzzy database. In such a database, the characteristic function for a fuzzy set maps to an arbitrary complete Brouwerian lattice L. From the query language perspectives, the language of fuzzy database, FSQL extends the regular Structured Query Language (SQL) by adding fuzzy specific constructions. In addition to that, L-fuzzy query language LFSQL introduces appropriate linguistic operations to define and manipulate inexact data in an L-fuzzy database. This research mainly focuses on defining the semantics of LFSQL. However, it requires an abstract algebraic theory which can be used to prove all the properties of, and operations on, L-fuzzy relations. In our study, we show that the theory of arrow categories forms a suitable framework for that. Therefore, we define the semantics of LFSQL in the abstract notion of an arrow category. In addition, we implement the operations of L-fuzzy relations in Haskell and develop a parser that translates algebraic expressions into our implementation.
