Spousal loss is a common, significant life event that can negatively affect multiple facets of individual health and psychological adjustment. Social support is one factor that is shown to improve adjustment following spousal loss, but much less is known regarding which facet of social support is most predictive of positive adjustment outcomes following spousal loss. This study examined the course of changes in mental health and well-being following spousal loss and which facets of social support are associated with better outcomes following spousal loss. Latent growth curve modeling was applied to data from 265 widowed individuals, ages 65 and older, across four assessments (baseline, and 6-, 18-, and 48- months following spousal loss). I examined the following research questions: (1) adjustment following spousal loss will follow a trajectory of an increase in depressive symptoms and anxiety and decrease in well-being with a leveling-off over time, with between-person differences, and (2) emotional support and instrumental support given will lead to more positive adjustment outcomes over time. Depressive symptoms followed the hypothesized trajectory but anxiety and well-being showed relative stability before and after spousal loss. Instrumental support was the most beneficial facet of social support, such that receiving more instrumental support was associated with lower levels of depressive symptoms and anxiety 6-months following spousal loss. Giving more instrumental support led to an increase in well-being following spousal loss. Instrumental support given and received led to increases in well-being as a function of spousal loss. The discussion focuses on whether and how these findings can help to identify ways through which support and help can be given to individuals to improve adjustment to spousal loss and fully recover.

Adolescent Prosocial Behavior at SES Extremes

Description
The literature has consistently established levels of adolescent maladjustment well above national norms for both socioeconomic (SES) extremes (Lyman & Luthar 2014). Yet literature on positive adolescent adjustment, and its protective or even corrective factors is lacking (Eisenberg, Zhou, & Coller, 2001). This study examined the effects of gender and…

The literature has consistently established levels of adolescent maladjustment well above national norms for both socioeconomic (SES) extremes (Lyman & Luthar 2014). Yet literature on positive adolescent adjustment, and its protective or even corrective factors is lacking (Eisenberg, Zhou, & Coller, 2001). This study examined the effects of gender and SES on parent attachment in relation to reports of prosocial behavior. Eleventh grade adolescents (N = 397) were recruited from two public high schools for academically-gifted students who were either high or low-level SES (i.e. the extremes). The students provided passive consent and answered questions on their demographics, perceived relationship with their parents, and tendency to behave in a prosocial manner. Multivariate analyses of variance and follow up analyses of variance were run by gender and SES to determine main effects for gender and SES on parent attachment and prosocial behavior. Regressions following preliminary correlations analyzed whether parental attachment predicted higher levels of adolescent prosocial behavior. Results demonstrated that females communicated with their mothers significantly more and reported higher levels of prosocial behavior than their male counterparts. Findings with regard to SES revealed that high SES adolescents reported increased parent attachment, whereas low SES adolescents reported higher levels of community\u2014based prosocial behaviors. Finally, certain dimensions of parent attachment predicted increases and decreases only in specific prosocial behaviors. Because prosocial behaviors change throughout adolescence, future ventures should consider a longitudinal analysis to obtain a more comprehensive picture of adolescent positive adjustment.

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.

The goal of this study was to examine whether there is any effect of phonotactic probability during the early phases of novel word recognition. In order to determine this, I performed two experiments. In Experiment 1, 33 adult monolingual English speakers learned 24 novel word-object pairings, half of which were high English phonotactic probability words and the other half were low English phonotactic probability words. I additionally included three conditions that varied the amount of exposures to each novel word-object pairing (i.e. One Exposure Condition, Two Exposures Conditions, and Five Exposures Condition). Experiment 2 was designed to clarify results found in Experiment 1, with improved randomization and fewer conditions (i.e. One Exposure Condition and Five Exposures Condition). The findings from both experiments were statistically significant in accuracy for Training condition, but not statistically significant for phonotactic probability nor for an interaction between phonotactic probability and Training condition. Although participants demonstrated learning across conditions there is no indication of a relationship between high and low phonotactic probability and novel word recognition. Collectively, these findings suggest that future studies will be necessary to determine if there is indeed an effect of phonotactic probability on early novel word recognition.

Supply & Demand, the phrase speaks to the tango between college graduates seeking employment & employers seeking talent. Recruiters desire candidates with employability skills to lead, but report significant skill gaps among applicants. This thesis aims to (1) define the skills gap evidenced by employers, (2) determine students’ career preparedness, and (3) identify strategies to bridge the gap among undergraduate students as they prepare to join the workforce. Qualtrics, an experience management, and survey platform, was used to reach and collect information from nearly 1,200 students in order to quantitatively assess their career development skills and needs. As part of this thesis, I have partnered with the T.W. Lewis Center for Personal Development, a center of Barrett, The Honors College at Arizona State University in an effort to test and provide effective solutions to bridge the employability skills gap. Through this collaboration, we have constructed a Career Development Workshop Series for students using the data collected from students. The workshop was built to teach students about professional skill topics that they desired to learn about, but could not find on or off-campus. The Lewis Center Career Development Workshop is a 5-part series with topics ranging from negotiation and job interviewing to strength-building. In each workshop, an expert is selected as the guest speaker to share their experience and insights with students as they prepare for their career journeys. Guest speakers include CEOs, entrepreneurs, business executives, and more. The series is intended to deepen students’ business acumen, so they can enter the workforce with a sustainable advantage and ultimately supported the professional and personal growth of over 100 students. The series serves as an example of ways our university can improve its career development offerings to students. In an increasingly competitive labor market, the research collected and solutions presented are designed to empower students in their careers.
