For many decades, the number of minority students, particularly Hispanics, dropping out from school has been noticeable to say the least (Rumberger, 1995). These students have in the past and continue in the present to struggle with the educational system, and it is certain, but not clear, that various factors contribute to Hispanics’ poor academic performance and not being able to graduate from High School (Rumbaut & Cornelius, 1995). Some of these factors are organized in three groups: School-Related; Parental-Related; and Student-Related. Thus, this study is an attempt to understand how immigrant students and parents are currently responding to the challenges of dealing with a foreign educational system. The focus is primarily on how students have to manage a sense of identity while they are trying to incorporate to their schools, and how parents are supporting their children and keeping a dialogue with the schools. It was hypothesized that students’ overall ethnic identity would correlate significantly with students’ psychological sense of school belonging. Quantitative results showed no statistical correlations between students’ ethnic identity and students’ sense of school membership. A forced entry multiple regression analysis was conducted to evaluate if any of the subscale scores on the MEIM predicted sense of school belongingness. The predictors were Affirmation and Belonging, Ethnic Identity Achievement, Ethnic Behaviors, and Other-group orientation, while the criterion variable was the total score on the PSSM. The Affirmation and Belonging subscale was the only subscale that was significantly related to psychological sense of school belongingness.

People aged 65 and older account for 12.8% of the population and for 30% of all visually impaired individuals. Age-related Macular Degeneration (ARMD) has been identified as a significant public health issue, with a potential 8 million Americans at risk. While the literature supports a connection between LOC and adaptation to ARMD, there is a gap in the current literature supporting this relationship even when other factors are controlled (i.e. age, sex, education, type of ARMD, when diagnosed, the use of medical treatments, the use of visual assistance devices, participant engagement in rehabilitation, and depression). The present survey study used hierarchical regression to examine the relationship between LOC and adjustment to ARMD while controlling for these factors. A sample of 75 adults aged 60 and older diagnosed with ARMD for at least 6 months completed the Multidimensional Health Locus of Control Scale-Form C (MHLC), the Adaptation to Age-Related Vision Loss Scale (AVL) and the Geriatric Depression Scale-Short Form (GDS). LOC accounted for 30% of the variance in adjustment beyond what was explained by the control variables, with higher internal LOC being associated with greater adaptation to loss. The present results add to the existing literature and enhance social change initiatives by guiding the development of interventions to mitigate the difficulties experienced by people with ARMD, reduce their dependency on others, and improve their ability to maintain their quality of life.

Workplace bullying is a global problem that leaves workers emotionally harmed and organizations financially strapped; yet in many cases, business leaders fail to adequately address the problem. The purpose of this research was to determine if the top leader had a direct impact on the presence of bullying within the workplace. Based on personality trait theory as a theoretical foundation, the key issue this study explored was the relationship between the presence of workplace bullying and observed narcissistic behaviors exhibited by the top leader. Participants consisted of 84 human resources professionals reporting directly to the CEO/president of companies located in the United States. Observer-rated assessments were used to measure the leader's observed narcissistic behaviors along with the prevalence of bullying within the workplace. Logistic regression and Pearson correlation were used to analyze assessment data. Results revealed a strong and positive relationship between top leaders' observed narcissistic behaviors and the presence of bullying within the organization. These results suggest the top leader may not only directly impact the presence of workplace bullying, but may actually create the problem. This study contributes to social change by providing support for the need to use personality assessments when hiring or promoting top leaders. By identifying those who contribute to the sustainability of bullying, these individuals can be excluded from the selection process and workplace bullying will therefore be minimized, improving the well-being of employees and the financial performance of organizations, world-wide.

<p>Sex differences, hormones and intrasexual competition and their relation to social status and romantic partner attraction were examined, uniting two bodies of literature: status-striving and romantic attraction. In Chapter 2 different forms of social status, (i.e., dominance, power, popularity, prestige) were examined as they relate to testosterone levels in men and women. Factor analysis revealed that dominance was a separate psychological construct from power, popularity and prestige. Furthermore, a positive association was shown between dominance and testosterone levels whereas lower testosterone levels were associated with the power, popularity and prestige composite. In Chapter 3 psychopathy and indirect aggression were examined in relation to cortisol levels, again in men and women. Results indicated that lower cortisol levels were associated with primary psychopathy and higher cortisol levels were associated with secondary psychopathy, in women only. Results also showed that primary psychopathy but not secondary psychopathy was positively correlated with indirect aggression. In Chapter 4, romantic attraction was examined from an evolutionary perspective to predict the characteristics of people who invade an existing romantic relationship as well as those characteristics that predict people who are targets for defection away from their primary romantic relationship. In men, successful mate poaching was best predicted by high self-esteem, cold affect, and criminal tendencies. These men also showed lower levels of testosterone and higher levels of cortisol. In women, physical attractiveness best predicted success in mate poaching. For both sexes, physical attractiveness also determined the frequency of being a target for a poach. Collectively, these studies provide evidence to support behavioural patterns that are consistent with evolutionary ideas relating to social status acquisition and romantic attraction.</p> / Doctor of Philosophy (PhD)

The United States is experiencing a shortage of registered nurses, and institutions of higher education are unable to graduate enough prepared nurses to reduce this employment shortage. A significant relationship between personality traits and academic performance has been found; however, how personality traits combine with students' self-efficacy of job performance and stress susceptibility to impact nursing students' academic performance has yet to be demonstrated. This study, grounded in the five-factor model (FFM) of personality traits, self-efficacy, and stress theories, sought to determine whether self-assessments of the NEO-Five Factor Inventory, the Nursing Practice Self-Efficacy survey, and the Susceptibility Under Stress Survey would predict academic performance, as measured by grade point average (GPA). The sample consisted of 197 nursing students attending 2-year nurse education programs at 3 community colleges in the northeastern United States. This correlational, quantitative study examined the relationship among the personality traits of the FFM, self-efficacy of job performance, stress susceptibility, and the GPAs of nursing students. Multiple regression analysis was used to examine the strength of the relationship among the variables. Self-efficacy and conscientiousness were significant predictors of GPA. Given that nurse education programs are a rigorous field of study with high attrition rates, the implications for social change include the addition of specific types of support for nursing students to facilitate their progress and success in a competitive degree program that will benefit them and address the nursing shortage, which ultimately benefits hospitals and patients.

<p>I examine female aggression as a competitive strategy for achieving reproductive success. In Chapter 1 an evolutionary theory of female aggression is presented. In Chapter 2 intrasexual competition for mates is considered by examining longitudinal links between aggression and dating behaviour among male and female adolescents. Results indicated that indirectly aggressive boys and girls were significantly more likely to have a dating partner at 1-year follow-up. Adolescents who reported being victimized by their peers were significantly less likely to have a dating partner at follow-up.</p> <p>In Chapter 3 I examine female mate-guarding behaviour. Results demonstrated that aggression toward peers and partners was greater among heterosexual females who perceived intrasexual competitors as being more attractive than them. These links were mediated by romantic jealousy. Females perceiving themselves as more attractive than peers frequently reported being targets of females’ peer-aggression. The findings of chapters 2 and 3 suggest that females actively compete to attain and retain mates.</p> <p>Chapter 4 examines implications for male victims of female aggression. We found that male victims of female partner violence were lower in testosterone than were non-victimized males. Participants held more negative attitudes toward male versus female victims. Males were less likely to seek-help and were more likely to minimize their perceived victimization. These findings suggest threats to male dominance and greater stigma likely reinforce males’ minimization and concealment of victimization.</p> <p>This dissertation contributes to the field of aggression by empirically demonstrating evolutionary-based motives and functions of female aggression as a strategy for bolstering reproductive fitness.</p> / Doctor of Psychology (PsyD)

Experimental aesthetics research has been conducted since the nineteenth century. Interestingly, however, few studies have examined the perceived beauty of naturally shaped objects. In the current experiment, 204 participants were presented with a set of ten snowflake silhouettes that varied in complexity (perimeter relative to area); they were similarly presented with ten randomly-shaped, computer-generated, solid objects that also varied in complexity. For each stimulus set, the participants selected the single snowflake or object that was the most beautiful (Fechner’s method of choice). The results for the solid objects replicated the findings of earlier research: the most and least complex objects were chosen as the most beautiful. Moderately complex objects were rarely selected. The results for the snowflakes were different. For these visual stimuli, the least complex snowflakes were almost never chosen; only the complex snowflakes were perceived to be most beautiful, with the aesthetic preference increasing with increases in complexity.

Life-stories offer an approach to understanding personality processes within a larger, developmental context. This study examines the role that one area of a person’s larger context (namely romantic relationships) plays in that person’s life-story. Specifically, the study examines whether this role changes over the lifespan. Nineteen students from a consortium of colleges in southern California, and an equal number of older adults living in a nearby retirement community, were interviewed about their romantic relationship history. The interview was semi-structured and asked participants about past and current relationships, and their most meaningful relationship overall. The interviews were coded for the themes of agency, redemption, and contamination, reported self-growth, and an additional variable called unprompted discussion of sexuality that was added based on a series of unexpected occurrences during the interviews. The results showed significant differences in both agency and unprompted discussion of sexuality between the romantic relationship narratives of young and older adults. However, no significant differences were found between the age groups on any of the other three variables, or between the sexes on any of the five variables. The results not only help us to better understand the ways in which our stories about our romantic relationships change across the lifespan, but also suggest significant differences between how younger and older adults think about love and sex.

Organizational justice and citizenship behaviors are important components that contribute to an organization’s overall effectiveness. Additionally, when an employee enters into a new organization, they form psychological contracts with their employer that consists of elements such as fairness and consultation. This study aimed to integrate the literature on organizational justice, psychological contract, and organizational citizenship behaviors, as well as look at the possible effects uncertainty may play. Specifically, it was proposed that psychological contract would mediate the moderating effects of uncertainty and justice in predicting prosocial behavioral intentions. Results did not support the hypothesis. Interestingly, however, identification with the university seemed to play a role in the uncertainty by fairness interaction in predicting perceived contract fulfillment.

Engagement is an increasingly important construct in organizational and educational settings. Research indicates that engagement is positively related to satisfaction, commitment, and performance in the workplace. This study investigated the relationship of Total Engagement to complete a thesis with Self-Determination Theory individual motivational constructs, the personality constructs of Psychological Capital and Core Self-Evaluations, and the experiential construct of Flow Propensity. The results indicated significant relationships between all constructs and engagement. Further, Psychological Capital and Flow Propensity explained 55% of the variance in Total Engagement to complete a thesis.
