Description
The frontostriatal reward circuit serves an underlying role in reward processing, cognitive planning, and motor control in the context of achieving a goal. Furthermore, research suggests a relationship between the reward circuits and behavior expressed in Attention Deficit Hyperactivity Disorder (ADHD); however, the specific structural differences of the reward circuits in those with ADHD remain ambiguous. Diffusion tensor imaging (DTI) techniques were used to analyze diffusion weighted magnetic resonance imaging (DWI) data in order to examine the structural connectivity of frontostriatal reward pathways in ADHD adolescents compared to typically developing (TD) adolescents. It was hypothesized that measures of impulsivity would be predicted by white matter tract integrity measures in frontostriatal tracts related to affective processing (ventromedial prefrontal cortex to ventral striatum, vmPFC) in adolescents with ADHD, and that there would be reduced tract integrity in tracts related to executive control (dorsolateral prefrontal and anterior cingulate cortex—dlPFC and ACC, respectively). Frontostriatal tracts as well as the hippocampus and amygdala were examined in relation to age and impulsivity using both correlation and regression models. Results indicated that impulsivity declined with age in the TD group while no significant trend was identified for the ADHD group. The hypotheses were not supported and results for both predictions on the affective and executive circuits showed opposite trends from what was expected.

Description
Posttraumatic Stress Disorder (PTSD) affects nearly 10% of adult women in general population samples. In populations of impoverished ethnic minority women, those lifetime prevalence rates may possibly exceed national averages due to lack of mental health resources. Mothers with PTSD are more likely to exhibit negative parenting styles and experience higher levels of perceived parenting stress, both of which are associated with poor child outcomes. However, there is a lack of evidence on how maternal PTSD may affect parenting for ethnic minority mothers. This study evaluated the prevalence of lifetime PTSD and its effects on parenting stress and infant problem behaviors in a sample of 322 low-income Mexican-American mothers (mean age = 27.8; 86% born in Mexico). Lifetime PTSD diagnoses were assessed at a prenatal home visit (24-36 weeks gestation) using the WHO Composite International Diagnostic Interview (CIDI). Mothers reported parenting hassles at 24-weeks postpartum (PDLH; Crnic & Greenberg, 1990), and child problem behaviors at infant age one-year (BITSEA; Briggs-Gowan et al., 2004). I hypothesized that 1) women with PTSD would report more parenting stress than women without PTSD, 2) women with PTSD would report more infant problem behavior symptoms than women without PTSD, and 3) parenting stress mediates the relationship between PTSD and infant problem behavior. Results found that 16.5% of women met criteria for past or present PTSD. Compared to women without PTSD, women with PTSD reported more parenting stress but a similar level of infant problem behaviors. Parenting stress significantly mediated the relationship between maternal PTSD and infant problem behaviors. Study findings suggest a need for mental health screenings during prenatal care in order to promote the healthy development of high-risk children.

Description
The NBA has experienced success because of its ability to adapt and reform business operations to reflect dynamic economic conditions. This critical analysis uses the Collective Bargaining Agreement to explore the NBA operational structure, examine the current state of affairs, and propose solutions to fundamental issues. Included is an in-depth investigation into correcting team financial reporting and fixing market inequality across the league. Most notably, a proposal to restructure the current revenue sharing system is presented. By progressing the system to correlate winning with team financial performance, there is potential to improve competition and alleviate existing conflict. This will produce a better overall product for the NBA that drives more consumer interest, yields more revenue, and supports stronger international growth opportunity.

Description
Ford Motor Company has remained a staple U.S. auto manufacturer in both the American and worldwide markets, ranking 2nd only behind General Motors on the Fortune 500. Ford Motor Company is currently faced with an industry wide shortage of automotive technicians. Successfully addressing this issue and taking action is crucial for Ford to remain competitive in its ability to efficiently service customers' vehicles. Ford must have a comprehensive strategy to interest students in automotive service careers as well as improve their current recruiting tactics. In order to create this plan, I conducted an external analysis of the service technician market as well as internal analysis of Ford Motor Company. It is vital for Ford Motor Company to be aware of the external environmental trends in the technician market. The changing demographic of the technician workforce presents a quickly approaching hurdle for dealers to hire millennial technicians to replace their retiring master technicians. The societal education shift away from vocational training has drastically reduced the number of high school students interested technical careers but opens the opportunity for Ford to create awareness about opportunities in the industry. Ford must also modernize their current recruiting tactics to appeal to millennial candidates through social media and online job postings. This plan will focus on maximizing Ford's strengths in the market including their industry leading number of students receiving Ford TCEP training and excellent field operations teams. Ford will also have to improve current dealership recruiting standards and combat competitors offering higher starting hourly salaries for entry level technicians. My strategy will also explore opportunities for Ford to expand the number of schools with TCEP curriculum, hire a larger percentage of TCEP students at dealerships, and improve high school awareness about the benefits of pursuing a career in the automotive service industry. My technician recruiting marketing plan is intended to be utilized as an integrated effort between Ford Corporate and its network of retail dealerships.

Description
This paper explores the idea of xenophilia and the circumstances under which it may occur. Xenophilia is the preference for an outgroup member over an ingroup member. This preference does not have to be amicable, and in fact can be exploitative under certain circumstances. Previous research indicates that xenophobia is much more common, but a few researchers have found support for the existence of xenophilia. To experimentally test the circumstances under which xenophilia might occur, I conducted a survey-based experiment on Amazon’s Mechanical Turk. This consisted of directed visualizations that manipulated participant goal (self-protection vs. mate acquisition) and the resources offered by both a fictitious outgroup and the hometown ingroup, followed by measures of ingroup/outgroup preference. I hypothesized that when the resource offered by the group addressed the participants’ goal, they would prefer the group with the “matched” resource—even if it was the outgroup providing that resource. My hypothesis was not supported, as the univariate analysis of variance for preference for the outgroup was not significant, F (2, 423) = .723, p = .486. This may have occurred because the goal manipulations were not strong enough to counteract the strong natural preference for ingroup members.

Description
Las Vegas, Nevada has been considered the "Entertainment Capital of the World" bolstering what seems like endless possibilities and attractions for those who come looking to have a good time. From the many storied casinos that line The Strip, to replicas of wonders of the world, and the countless attractions the city hosts such as the world-renowned shows and other blockbuster events, Vegas seems to have it all. However, one thing seems to be missing \u2014 professional sports. This project highlights the introduction of Las Vegas' first ever professional sports franchise, the Golden Knights, along with the journey it took to get there. Beginning with origins of professional hockey and the foundation of the NHL in 1927, the League has grown substantially in size that spans over 19 states, from coast to coast, across the country. From the NHL's first expansion in 1967, the league has witnessed immense growth through the influence of broadcasting rights and seen through increased television ratings, in-game attendance numbers, and youth hockey registration numbers in markets throughout the United States. The growth and promotion of hockey culture in regions outside the North and Northeastern part of the nation have led to the recent expansion of hockey into Las Vegas. This thesis covers the steps in which the new Vegas franchise was formed, in addition to the key factors that led to the team's incredible inaugural season success which has marked them the most successful expansion team ALL North American sports history. Finally, after displaying the contributions the Golden Knights have had on the ice, this thesis illustrates the impact the team has made off the ice both for the Las Vegas economy and the local community. Through the construction of Vegas' state of the art arena, the franchise's ticket and merchandise sales, the media value and attention the team has brought to Las Vegas, and the increase in jobs created for the city, the Golden Knights have been generating hundreds of millions of dollars for Las Vegas. As the city's first professional sports franchise, the Golden Knights have truly become a successful addition to the "Entertainment Capital of the World," and to the NHL itself.

Description
This thesis explores revenue management within the domestic United States airline market from a broad research base including peer-reviewed journals, professional articles, industry studies, government statistics, and consumer surveys. Among other topics, the thesis synthesizes data from these sources to effectively understand how airlines turn a profit in one of the world’s most competitive industries. Within that scope, the thesis explores the history of the industry, how technology affects revenue management strategies, how deregulation affected competition, and how different costs impact an airline’s operations. This is accomplished primarily with the literature review, governmental statistics, and professionals in the field. Moreover, the surveys provide a human element to these numbers. Namely, how does the public perceive the airline industry? Moreover, what drives the decision to purchase a seat on a particular airline over another? The research suggests four main trends in the US’ airline industry: increase in low-density long-range routes, high-density short-range routes, redefining high-density routes’ capacity utilization, and expansion of the Low-Cost Carrier. The former, due to the scope of this thesis, will be diminished in its analysis. The latter three will be expanded upon. A case study of three U.S. airports identified as small, medium, and large is present at the end to expand upon a hypothesis presented.

Description
Social media has grown into one of the most popular tools in the marketing industry. As social media continues to evolve, it allows for even greater transparency, communication, and relationships among users and businesses. There is no doubting that social media is an effective way to foster brand loyalty and a community of brand advocates, however successful social media marketing requires a depth of knowledge, understanding of the market, and an established strategy. Social media has been extremely effective in sports business as it allows organizations to create a community for their fans where they can find real-time news, promotions, content, and information about their favorite teams. As an intern for the New York Mets tasked with covering the Arizona Fall League, my experience provided first-hand insight into the use of social media in the MLB. Through an analysis of the New York Mets social media strategy, this thesis discusses the effectiveness of social media as a marketing strategy, best practices, and current trends to provide a well-rounded analysis of the successful implementation of this tool.

Description
Incidents relating to professional/collegiate athletes and their use of social media have been a prominent topic in the news for the last several years. For collegiate athletes, a distasteful, offensive post can have a substantial impact on the rest of their lives, as he/she can have scholarships revoked, legal action taken upon them, and professional offers cut. An athlete's poor actions will affect their brand image and that of the school whose uniform they wear. Outcry over these incidents have caused teams, themselves, to compensate in a variety of ways. The following thesis is a narrative representation of these incidents, resulting outcry, and desperate compensation. The narrative touches upon the impact social media can have on a team, athletic department, and university. It explores the rules/restrictions of social media, marketing concepts such as branding, the right to free speech, and the impact/consequences of bad choices. The narrative is preceded and followed by analysis of real-world examples to provide sound rationale for the actions taken in the narrative.

Description
The present study utilized longitudinal data from a high-risk community sample (n= 377; 166 trauma-exposed; 54% males; 52% children of alcoholics; 73% non-Hispanic/Latino Caucasian; 22% Hispanic/Latino; 5% other ethnicity) to test a series of hypotheses that may help explain the risk pathways that link traumatic stress, posttraumatic stress disorder (PTSD) symptomatology, and problematic alcohol and drug use. Specifically, this study examined whether pre-trauma substance use problems increase risk for trauma exposure (the high-risk hypothesis) or PTSD symptoms (the susceptibility hypothesis), whether PTSD symptoms increase risk for later alcohol/drug problems (the self-medication hypothesis), and whether the association between PTSD symptoms and alcohol/drug problems is due to shared risk factors (the shared vulnerability hypothesis). This study also examined the roles of gender and ethnicity in these pathways. A series of logistic and negative binomial regressions were performed in a path analysis framework. A composite pre-trauma family adversity variable was formed from measures of family conflict, family life stress, parental alcoholism, and other parent psychopathology. Results provided the strongest support for the self-medication hypothesis, such that PTSD symptoms predicted higher levels of later alcohol and drug problems among non-Hispanic/Latino Caucasian participants, over and above the influences of pre-trauma family adversity, pre-trauma substance use problems, trauma exposure, and demographic variables. Results partially supported the high-risk hypothesis, such that adolescent substance use problems had a marginally significant unique effect on risk for assaultive violence exposure but not on overall risk for trauma exposure. There was no support for the susceptibility hypothesis, as pre-trauma adolescent substance use problems did not significantly influence risk for PTSD diagnosis/symptoms over and above the influence of pre-trauma family adversity. Finally, there was little support for the shared vulnerability hypothesis. Neither trauma exposure nor preexisting family adversity accounted for the link between PTSD symptoms and later substance use problems. These results add to a growing body of literature in support of the self-medication hypothesis. Findings extend previous research by showing that PTSD symptoms may influence the development of alcohol and drug problems over and above the influence of trauma exposure itself, preexisting family risk factors, and baseline levels of substance use.
