Substance use disorders are chronic brain disorders and must therefore be treated on an ongoing basis. Accordingly, the concept of recovery capital has been developed to account for the internal and external resources that an individual can mobilize in order to recover from a substance use disorder. However, the concept has scarcely been applied to emerging adults. Although they are at twice the risk of developing a substance use disorder relative to their adult or adolescent counterparts, emerging adults in addiction and recovery are understudied. This phenomenological study aims to explore and describe the experience of emerging adults in recovery and to identify the barriers and facilitators to their recovery. The informants (n=8) were 18-25 year olds in recovery from substance use disorders. Data was collected using semi-structured interviews and subsequently analyzed for emerging themes. The results from this study suggest that the developmental tasks facing emerging adults are exacerbated in addiction and recovery.

In face of the rapid globalization, more and more emerging market MNEs (EMNEs) are assigning expatriates to establish and manage overseas tasks in order to gain the competitive advantages in global markets. Consequently, the issue of expatriate management within the context of EMNEs has become an important concern in the field of IHRM. The purpose of the thesis is to delineate how expatriate management of Chinese MNEs that shaped by unique Chinese informal institutional environment may impact upon the expatriate effectiveness (work adjustment and job performance) in foreign countries. The thesis uses a qualitative research and collects empirical data from 11 Chinese expatriates working in 3 different Chinese MNEs’ Nordic divisions. The empirical results reveal the fact that Harmony is positively related to work adjustment through indoctrinating the specific corporate value, Group Orientation (family attachment) has positive relationship with job performance, Top-down control has negative relationship with work adjustment because of the hierarchy pressure, and Guanxi has no link with expatriate effectiveness under the given regulations and staffing policies. In the context of EMNEs, the influences of four different informal institutional factors are able to intervene the IHRM practices so as to increase or decrease the expatriate effectiveness.

This thesis is a collection of essays where I explore and extend the study of the role of financial frictions for the determination of asset prices, financial stability, and economic resilience. The frictions included in the analysis are individual and aggregate uncertainty, agent heterogeneity, money, liquidity and default. The first essay is an empirical study that motivates my research objectives. This work starts with the exploration of the role of liquidity on asset prices, specifically on sovereign bonds of emerging countries. I present a comprehensive model where I developed a novel methodology for finding the role of liquidity in the determination of asset prices during the financial crisis. In the second essay, illuminated by the empirical findings, I apply and expand the general equilibrium theory of money, default and financial stability. The contributions at the theoretical level are the extension of two-period model with discrete state space to the infinite horizon dynamic stochastic setting, and the inclusion of liquidity restrictions. In the third essay, I further extend this framework, allowing for production technology and endogenous market liquidity. Given the theoretical setting, I have analyzed the responses of financial stability and economic performance variables to real and financial shocks. Finally, in the fourth essay I produce an empirical application of this work. I apply a novel semi-parametric financial stability metric, and evaluate its relevance for the determination of asset prices, in the presence of liquidity restrictions. As a result, this thesis suggest plausible explanations for financial and economic issues that conventional models have not dealt with adequately.

This study is focused on exploring quality of life in young adults in the autism spectrum and the factors that contribute to their own perception of satisfaction with their lives. Autism Spectrum Disorder is a neurodevelopmental disability that is associated with deficits in social interaction and communication and with restricted and repetitive behaviors (American Psychiatric Association, 2013). There has been a documented increase in the diagnosis of Autism Spectrum Disorders (ASD), making it to be one of the fastest growing diagnosed disabilities in children (Hartley-McAndrew, 2014). In the United States, the prevalence of ASD is approximately 1 in 68 children, with 1 in 42 among boys (CDC, 2014). With this increase in recognition of the disorder, adult outcomes have become an increasing priority for this population. While the concept of quality of life has been used in the field of intellectual disabilities for decades, the factors contributing to quality of life of persons with autism spectrum disorder (ASD) have received relatively little attention. The aim of this study was to examine the influences of degree of disability, social and communication ability, academic success, employment, and independence and autonomy on quality of life in young adults with high-functioning autism. Participants (N @ 230) were individuals from the dataset of the National Longitudinal Transition Study 2 (NLTS2) who had a diagnosis of autism spectrum disorder (ASD) (Cameto, et al., 2004). Results indicated that employment, social involvement, communication (being able to communicate, converse, and understand), and autonomy were significant in predicting higher quality of life. Factors found not to contribute to QoL included degree of disability (Woodcock-Johnson III) and education. This study helps to shed light on the development of higher quality of life in young adults with ASD and highlights areas for future research and training with these members of society.

The developmental stage of emerging adulthood often poses substantial challenges that negatively impact bereavement experiences (Schultz, 2007; Tanner & Arnett, 2009). Some emerging adults may be even more at risk for adverse grief outcomes due to individual differences such as gender and ethnicity, but very few studies have investigated these variables within the population. We addressed this gap in the literature by investigating the influence of gender and ethnicity on college students’ bereavement experiences using the Hogan Grief Reaction Checklist (HGRC; Hogan, Greenfield, & Schmidt, 2001) Results indicates a significant relationship between ethnicity and levels of personal growth, use of religious coping, and type of loss. The present study found no clinically significant differences in male and female college student bereavement characteristics.

The current study used a three-phase mixed-methods design to produce a new self-report measure of the strategies that college students use to cope with the death of a loved-one. College students are commonly bereaved and may be in the process of undergoing important developmental tasks related to emerging adulthood. However, the application of grief-specific stress-and-coping theories (i.e., the Dual Process Model of Coping with Bereavement) to this population has been hampered by measurement issues. The current study aimed to address the flaws asserted above through the use of a mixed-methods scale development design. To this end, the researcher made use of the discussion component of a bereavement-focused special topics course to refine a focus-group facilitation guide and generate a preliminary list of content domains. In Study 1, three bereaved students participated in a formal focus-group. Three graduate-level bereavement researchers drew from the qualitative data available from the Pilot Study and Study 1 to develop a pool of 192 items for use in quantitative analysis. In Study 2, these items were administered to a sample of 700 bereaved undergraduates. Exploratory and Confirmatory factor analyses suggested that a 5-factor model was the best fit for the data. Results suggest that bereaved students use a variety of strategies when coping with bereavement, including using drugs and alcohol, seeking support from others, accessing religious faith, exploring new relationships and identities, and experiencing depression symptoms. Preliminary support was provided for the validity of a 26-item coping strategies measure with five subscales named the GCOPE.

Research suggests college students with high incidence disabilities experience more distress than their peers without disabilities as they adapt to college. The expressive writing paradigm developed by Pennebaker and Beall (1986) effectively reduced distress in college students and other nonclinical samples when participants wrote about emotions they experienced surrounding an upsetting event. Previous research on expressive writing has not addressed the effectiveness of the paradigm with students with disabilities. A randomized control trial study examined changes in distress and daily hassles for participants with disabilities who engaged in expressive writing compared to a control condition in which participants wrote about non-emotional topics. Emotional competencies and coping were also explored as possible proximal outcomes, while distress at baseline and social support were explored as possible moderators of expressive writing outcomes. Fifty seven students, 51% male and mostly European-American (83.6%), from a large, public university and a local community college both in the Southeastern United States, wrote for 15 minutes on three consecutive days on their own personal computers, with assessment at pre-test, post-test and 30-day follow-up. Expressive writing did not significantly decrease stress or daily hassles, nor did treatment condition differ from the control condition on any of the factors examined. Discussion of participant factors explored possible ceiling effects due to low baseline distress scores and possible limitations related to employing a sample of students with disabilities who are currently receiving college-level support services. Other methodological and procedural issues were also discussed as they relate to best expressive writing practices as well as meeting the needs of students with disabilities. For example, although use of the computer for writing was deemed important for this group of participants, longer writing sessions that may be necessary to impact psychological outcomes could be difficult for students with disabilities. Future directions include qualitative analysis of writing samples in order to develop areas of concern for this population, beginning and ending expressive writing to align with the college academic calendar, as well as use of a control group without disabilities in order to control for baseline levels of distress.

Marijuana use among American young adults is rising, and perceptions of harm are declining. Individual states continue to enact more lenient marijuana use and possession laws. Marijuana use is associated with many serious negative outcomes. Thus, marijuana use among this age group has become a public health concern. According to Primary Socialization Theory, parents exert their influence on youth behavior through the parent-adolescent bond and through communication. Previous researchers have identified parent-offspring communication about alcohol and tobacco as a potentially important target of prevention efforts. Little research has yet explored marijuana communication and its potential influence on use-related outcomes. This study sought to model the influence of the parent-adolescent bond and parent-offspring communication about marijuana on marijuana use and problems related to use. In order to model this influence, the Communication about Marijuana (CAM) measure first was developed. In Study 1, an initial pool of items tapping marijuana communication was tested using a sample of 18-25 year old (M=20.22) undergraduate students (N=433). Confirmatory factor analyses were performed to test the fit of the data to the proposed model. In Study 2, a revised CAM measure was tested with a second sample of 18-25 year old (M=20.40) undergraduate students (N=432). The final measure included four content topic factors comprising 9 items, and 3 descriptive items tapping communication context. Structural equation models were specified to model the parent-adolescent bond and marijuana communication content on student self-reported past year marijuana use and marijuana use problems. Results suggested that the parent-adolescent bond was protective on marijuana use frequency, while models including only the manifest variable parental support better fit the data with regard to marijuana use problems. Communication content was somewhat differentially related to outcomes. Discussions encouraging abstinence, offering advice on peer pressure and monitoring use were related to more frequent use. Communication that conveyed disappointment about marijuana use and offered advice about peer pressure and choosing non-using friends was related to more marijuana use problems. Positive relations between communication and use outcomes were unexpected, but may reflect reactive parenting. Results and implications for future research are discussed in the context of the extant literature.

Bereavement is an important research area as it can result in grief reactions that lead to serious psychological and health consequences, particularly for the at-risk group of emerging adults (Arnett, 2000; Balk, Walker, & Baker, 2010; Fisher, Murray, & Frazer, 1985; Stroebe, Schut, & Stroebe, 2007). Expressive writing is a well-researched intervention for trauma and adjustment, yet research repeatedly has revealed null results with the classic Pennebaker paradigm as a bereavement intervention (Stroebe et al., 2002; Stroebe, Schut, & Stroebe, 2006). It may be premature, however, to conclude expressive writing is ineffective for the bereaved due to limitations in extant research. For example, Pennebaker’s paradigm is based on the premise that participants freely choose the stressful topic to write about, whereas expressive writing bereavement studies have required participants to write about their loss (Collison & Gramling, manuscript in preparation). The present study reports on data from a larger study (Konig, Eonta, Dyal, & Vrana, 2014; N=246) that assessed psychological and physiological outcomes in college students who wrote about a traumatic stressor using Pennebaker’s paradigm. This provided the opportunity to rigorously test it with bereavement and compare death loss to other forms of trauma. Analyses examined the impact of expressive writing with the bereaved who freely identified death loss as the traumatic stressor (n=69) and were randomly assigned to either emotional disclosure or control writing on outcome measures of physical symptoms (PILL), event-related distress (DTS), and depression (CES-D). Linguistic Inquiry and Word Count (LIWC; Pennebaker, Mayne, & Francis, 1997) and Latent Semantic Analysis (LSA; Campbell & Pennebaker, 2003) results were also used to compare these groups. Exploratory analyses investigated potential differences between the bereaved and those who endorsed a non-bereavement trauma (“other trauma”; n=71) using outcome measures and text analytic techniques (i.e., PILL, DTS, CES-D; LIWC, LSA). Results were consistent with findings from previous expressive writing studies with the bereaved, in that the intervention resulted in no detectable benefits when compared with control writing. No remarkable differences between the bereaved and “other trauma” participants emerged. Researchers’ time may be better spent examining more clinically relevant writing exercises for bereavement interventions.

In the last decade emerging contaminants research has intensified in a bid to answer questions about fate, transport, and effects as these chemicals as they get released into the environment. The chemicals of interest were the antimicrobials; triclocarban (TCC) and triclosan (TCS), and a metabolite of triclosan, methyl triclosan (MTCS). This research was designed to answer the question: what is the fate of these chemicals once they are released from the waste water treatment plant into receiving streams. Three different assessment methods; field monitoring, in-situ experiments, and laboratory studies were used to answer the overall question. TCS, TCC, and MTCS levels were measured in surface water, sediment and the Asiatic clam Corbicula fluminea. Field studies were conducted using four sites at Pecan Creek, Denton TX. Levels of all three chemicals in clams were up to fives orders of magnitude the water concentrations but an order of magnitude lower than in sediment. Highest sediment levels of chemicals were measured in samples from the mouth of Pecan Creek (highest organic matter). TCC was the most and TCS was the least accumulated chemicals. In-situ and lab studies both indicated that uptake of these chemicals into the clams was very rapid and measurable within 24hours of exposure. The after clams were transferred into clean water most of the compounds were depurated within 14 days.
