Cannabis use has been purported to cause an amotivation-like syndrome among users. The purpose of this study was to investigate whether third party observers noticed amotivation among cannabis users. Participants in this study were 72 undergraduate university students, with a mean age of M=19.20 years old (SD=2.00). Participants nominated Informants who knew them well and these informants completed a version of the 18-item Apathy Evaluation Scale. Results indicated that more frequent cannabis use was associated with higher informant-reported levels of amotivation, even when controlling for age, sex, psychotic-like experiences, SES, alcohol use, tobacco use, other drug use, and depression symptoms (β=0.34, 95% CI: 0.04, 0.64, p=.027). A lack of motivation severe enough to be visible by a third party has the potential to have negative social impacts on individuals who use cannabis regularly.

Description
Youth who turn 18 in the foster care system often face the difficulty of transitioning to adulthood without traditional emotional and financial supports. Early experiences of trauma impact their mental health and receipt of services both while in care as well as decisions whether to continue services after leaving care.
Using the behavior analytic model, this dissertation explores the challenging and supportive situations former foster youth experience with mental health services while transitioning to adulthood. Qualitative interviews and focus groups inform the development of a quantitative instrument in a mixed methods, sequential exploratory research design. The resulting instrument identifies the most intense and frequently encountered situations former foster youth experience, related to their mental health and transitions to adulthood.
Results indicate the most challenging situations foster youth experience during the transition are related to overwhelming expectations, receiving mixed messages from professionals, feelings of isolation, and a lack of voice and choice with regard to mental health services. Young adults in this study also emphasized the importance of responsive engagement, self-efficacy, and consistency in relationships both formally and informally.
This research provides important implications for social work practice, policy, and education. Acknowledging the voice of foster youth gives them a choice in services and allows for realistic transition planning. Developing problem-solving skills and a support network beyond foster care are necessary strategies of preparation to age out. Finally, practitioners should recognize the impact of trauma and other contextual factors when conducting assessment and treatment, to promote positive outcomes.

Description
Vitamin B12, found only in animal products, is a water-soluble vitamin important for DNA methylation, purine and pyrimidine synthesis, and the myelination of nerves. Symptoms of vitamin B12 deficiency include anemia, gait disturbances, altered vibration proprioception, impaired vision, psychosis, depression, dementia-like illness, and ultimately death. Because vegetarians and vegans consume fewer animal products in their diet than omnivores, they are inherently more at risk for developing these symptoms of vitamin B12 deficiency. Thus, the purpose of this study is to examine the correlation between nervous system markers (balance, dexterity, and vibration sensitivity) and markers of vitamin B12 nutriture (serum B12 and serum holo-transcobalamin II) in a cross-sectional study (n=38). In addition, the impact of daily oral vitamin B12 supplementation on these markers in an 8-week randomized controlled trial was also examined (n=18). The results of the cross-sectional study revealed a moderate correlation (R=-0.351, p=0.031) between serum B12 and left-hand functional dexterity. The results of the intervention study revealed no significant time*group interactions for markers of nervous system functions and biochemical values (after the removal of outliers). In addition, the time*group interaction appeared to be larger for those individuals with a baseline serum B12 of less than 303 pmol/L. These results suggest that vitamin B12 supplementation may have a more pronounced effect on those individuals who are in a state of vitamin B12 depletion (<303 pmol/L serum concentration). In addition, the results also suggest that 8 weeks of oral supplementation is not a long enough period to create significant clinical change, and it is likely that improvements in neurological measures would require long-term supplementation.

Description
This exploratory quantitative study examined the risks and needs expressed by gender/sexual minority emerging adults in Phoenix, Arizona. Differences in experiences and perceived service needs between gender minorities and cisgender sexual minority emerging adults were also identified. Respondents (N=102) completed a 78-item questionnaire in March and April of 2015. Individuals reported high rates of risk factors and physical needs, with those individuals who were both gender and ethnic minorities more likely to report having a perceived service need than their cisgender white counterparts. In addition, the study found significant positive correlations between housing factors (i.e., having experienced homelessness, ever/currently being in foster care, not having a safe/stable living situation) and other risk factors and needs. Risk factors were also correlated with wishing for a different gender identity or sexual orientation. With the majority of the respondents reporting a service need, implications include the need for culturally competent and accessible services, as well as services that continue to build on the protective factors of having an accepting family, friend group, and a sense of belonging to a community.

Description
Life course criminology is characterized by a two-pronged approach to research. The first branch emphasizes social integration and involvement with pro-social institutions as turning points in the criminal career. The second branch of this work assesses how access to the institutions that facilitate social integration are conditioned by factors such as involvement in the criminal justice system. Theories of capital are chiefly concerned with social integration and the continuity of conventionality, conformity, and prosperity offered through social ties and social networks. Absent from life course criminology is a better understanding of how different forms of criminal capital can influence access to institutions like higher education, marriage, and employment during the transition to adulthood. Drawing on insights from distinct bodies of literature on peers, capital, and status attainment, the present study elaborates on the influence of criminal capital for (un)successful transitions to adulthood. Using three waves of data from the National Longitudinal Study of Adolescent to Adult Health (“Add Health”), the effects of adolescent criminal social capital on criminal cultural and human capital, and subsequent educational, occupational, and marital attainment in early adulthood are examined. Results from a series of regression models demonstrate that criminal social capital has minimal effects on fatalistic beliefs or thoughtful and reflective decision making, and that these forms of criminal capital generally have inconsistent effects on later life transitions. Implications for theory and future research are discussed.

Description
Intervertebral Disc Degeneration (IVDD) is a complex phenomenon characterizing the desiccation and structural compromise of the primary joint in the human spine. The intervertebral disc (IVD) serves to connect vertebral bodies, cushion shock, and allow for flexion and extension of the vertebral column. Often presenting in the 4th or 5th decades of life as low back pain, this disease was originally believed to be the result of natural “wear and tear” coupled with repetitive mechanical insult, and as such most studies focus on patients between 40 and 50 years of age. Research over the past two decades, however, has demonstrated that environmental factors have only a modest effect on disc degeneration, with genetic influences playing a much more substantial role. Extensive research has focused on this process, though definitive risk factors and a clear pathophysiology have proven elusive. The aim of this study was to assemble a cohort of patients exhibiting definitive signs of degeneration who were well below the average age of presentation, with minimal or no exposure to suspected environmental risk factors and to conduct a targeted genome analysis in an attempt to elucidate a common genetic component. Through whole genome sequencing and analysis, the results corroborated findings in a previous study, as well as demonstrated a potential connection and influence between mutations found in IVD structural or functional genes, and the provocation of IVDD. Though the sample size was limited in scale and age, these findings suggest that further IVDD research into the association of variants in collagen, aggrecan and the insulin-like growth factor receptor genes of young patients with an early presentation of disc degeneration and minimal exposure to suspected risk factors is merited.

Description
The current study examined effects of representations of relationships with parents on young adults’ representations of romantic relationships and self-esteem, with particular attention paid to the role of fathers, instability of representations, and bidirectional effects. Data were obtained from two waves (Waves 4 and 5) of a five-wave study. At wave 4, 287 young adults (mean age = 20) participated, and at Wave 5, 276 young adults (mean age = 22) participated. One-time interviews (Behavioral Systems Questionnaires; BSQ) were conducted to measure the level of representations of relationships with parents. Nightly diary checklists (7 nights at Wave 4, and 5 nights at Wave 5) were used to measure the level and instability of representations of romantic relationships (BSQ) and self-esteem (Rosenberg Self Esteem Scale). Two styles of representations, including secure versus dismissing (e.g., relying on parents or romantic partners when distressed versus not relying on them) and preoccupied (e.g., worrying about rejection and excessive dependency) were measured for relationships with parents and romantic partners. The results showed evidence for unique roles of fathers, instability of representations, and bidirectional effects. Relationships with fathers affected young adults’ self-esteem. More nightly fluctuations in security with romantic partners predicted higher levels of security with romantic partners, but only in the context of more secure relationships. More nightly fluctuations in self-esteem predicted more dismissive representations of fathers. Bidirectional effects involved young adults’ representations of both romantic relationships and self-esteem, and their representations of relationships with parents. The relation between instability of representations of romantic relationships and later security in romantic relationships might represent learning about romantic relationships. The relation between instability of self-esteem and later dismissive styles with fathers (e.g., not relying on fathers when distressed) at this age might be an indication of learning to become autonomous from fathers. Finally, I also hypothesize that during emerging adulthood, fathers tend to encourage children to solve their stress or problems by themselves, while mothers tend to still provide help when children are distressed. These suggested hypotheses should be examined in future research.

Description
ABSTRACT Many musicians, both amateur and professional alike, are continuously seeking to expand and explore their performance literature and repertory. Introducing new works into the standard repertory is an exciting endeavor for any active musician. Establishing connections, commissioning new works, and collaborating on performances can all work together toward the acceptance and success of a composer's music within an instrument community. For the flute, one such composer is Daniel Dorff (b. 1956). Dorff, a Philadelphia-based composer, has written for symphony orchestra, clarinet, contrabassoon, and others; however, his award-winning works for flute and piccolo are earning him much recognition. He has written works for such illustrious flutists as Mimi Stillman, Walfrid Kujala, and Gary Schocker; his flute works have been recorded by Laurel Zucker, Pamela Youngblood and Lois Bliss Herbine; and his pieces have been performed and premiered at each of the National Flute Association Conventions from 2004 to 2009. Despite this success, little has been written about Dorff's life, compositional style, and contributions to the flute repertory. In order to further promote the flute works of Daniel Dorff, the primary focus of this study is the creation of a compact disc recording of Dorff's most prominent works for flute: April Whirlwind, 9 Walks Down 7th Avenue, both for flute and piano, and Nocturne Caprice for solo flute. In support of this recording, the study also provides biographical information regarding Daniel Dorff, discusses his compositional methods and ideology, and presents background information, description, and performance notes for each piece. Interviews with Daniel Dorff regarding biographical and compositional details serve as the primary source for this document. Suggestions for the performance of the three flute works were gathered through interviews with prominent flutists who have studied and performed Dorff's pieces. Additional performance suggestions for Nocturne Caprice were gathered through a coaching session between the author and the composer. This project is meant to promote the flute works of Daniel Dorff and to help establish their role in the standard flute repertory.

Description
The present study examined whether a history of childhood sexual abuse would be related to attachment to mother, to father, and to friends, mattering to parents and to friends, and coping behaviors. In addition, whether use of force, duration of abuse, and severity of abuse were related to perceived negative impact of childhood sexual abuse was examined. Gender differences among survivors were also investigated. Specifically, from the initial sample of 258 young adults, 186 who met the age requirement were included in the tests of the hypotheses. All participants were between the ages of 18 and 25. Compared to those with no history of childhood sexual abuse (n = 109), survivors (n = 77) reported lower attachment to father and less mattering to parents. There were no differences in attachment and mattering to friends or in emotion-focused and problem-focused coping. When gender differences were examined among survivors, females reported greater use of problem-focused coping and perceiving their childhood sexual abuse experiences as more negative than did the male survivors. There were no differences among male and female survivors of childhood sexual abuse on emotion-focused coping. Force and severity, but not duration, were linked to more negative perceptions of the childhood sexual abuse. Attachment to mother emerged as a key variable in that attachment to mother was positively related to attachment to friends, mattering to friends, and the use of problem-focused coping. Stronger attachment to mother and attachment to father, but not a history of childhood sexual abuse, were related to more perceived mattering to parents. These results highlight the importance of attachment to caregivers in developing peer attachment and a sense of mattering to friends, problem-focused coping skills, and perceiving childhood sexual abuse as having a less negative impact on their lives. Clinical and research implications and suggestions for future directions are discussed.
