Description
In this dissertation Mexican American (MA) youths environmental risk contexts, HPA axis functioning and mental health symptomatology were investigated in two separate studies. In the first study, environmental risk contexts were examined utilizing a person-centered approach and focusing on MA adolescents' family, peer, and cultural risk factors in fifth grade (N = 750). Environmental contexts were then linked to mental health symptomatology in seventh grade. Results revealed three distinct environmental contexts: Low risk, Moderate risk-language, and High risk-peer. Youth in the High-risk peer context reported the highest levels of symptomatology; greater major depressive disorder (MDD), anxiety, conduct disorder (CD)/oppositional defiant disorder (ODD), and attention deficit hyperactive disorder (ADHD) symptoms than youth experiencing Low risk or Moderate risk-language context. Females, in particular, experiencing the High risk peer context appeared at greatest risk for MDD symptoms. Finally, adolescents in the Moderate risk-language context displayed similar levels of symptoms to the individuals in the Low risk context, with the exception of higher anxiety. This study suggested that MA youth live in unique environmental contexts and these contexts are differentially related to mental health symptomatology. In the second study, 98 MA youth participated in a three-day diurnal cortisol protocol in hopes of linking perceptions of discrimination and HPA diurnal cortisol rhythms. Results revealed that discrimination was related to greater overall cortisol output and marginally related to the cortisol awakening response and evening levels of cortisol. Results suggest that important physiological processes underlie the experiences of discrimination.

Description
Meteorology is an uncommon term rarely resonating through elementary classrooms. However, it is a concept found in both fourth and sixth grade Arizona science standards. As issues involving the environment are becoming more pertinent, it is important to study and understand atmospheric processes along with fulfilling the standards for each grade level. This thesis project teaches the practical skills of weather map reading and weather forecasting through the creation and execution of an after school lesson with the aide of seven teen assistants.

Description
Plants are essential to human life. They release oxygen into the atmosphere for us to breathe. They also provide shelter, medicine, clothing, tools, and food. For many people, the food that is on their tables and in their supermarkets isn't given much thought. Where did it come from? What part of the plant is it? How does it relate to others in the plant kingdom? How do other cultures use this plant? The most many of us know about them is that they are at the supermarket when we need them for dinner (Nabhan, 2009) (Vileisis, 2008).

Description
Restraint stress is the most commonly used laboratory stressor. It is difficult to characterize as psychological or physical, because past studies show psychological features, but the nature of confinement adds a physical dimension. This was the first study to investigate how experience with restraint stress affects brain response to the next stress without a physical burden. Pair-housed adult male rats were transported to a novel context and restrained or left undisturbed (6hr). The next day, rats were returned to the same context and were either restrained or left undisturbed in the context (n=8/group). After 90min, rats were euthanized to determine functional activation in limbic structures using Fos immunohistochemistry and to measure HPA axis reactivity through blood serum corticosterone levels. Regardless of day 1 experience, context exposure on day 2 enhanced Fos expression in CA1 and CA3 of the hippocampus, basolateral amygdala, and central amygdala. Conversely, other regions and corticosterone levels demonstrated modulation from the previous day's experience. Specifically, rats that were placed back into the restraint context but not restrained on day 2 showed enhanced Fos expression in the dentate gyrus suprapyramidal blade (DGSup), and infralimbic cortex (IL). Also Fos expression was attenuated in rats that received two restraint exposures in the IL and medial amygdala (MEA), suggesting habituation. Only the DG infrapyramidal blade (DGInf) showed enhanced Fos expression to restraint on day 2 without influence of the previous day. While context predominately directed Fos activation, prior experience with restraint influenced Fos expression in the DGSup, IL, MEA and corticosterone levels to support restraint having psychological components.

Description
The issue of adolescent dating violence is a relatively new field of research, but several studies have shown that adolescent dating violence is distinct from adult domestic violence and has its own implications and patterns. Many studies have shown that both males and females appear to be the victims and perpetrators of dating violence, and often times in abusive dating relationships, the perpetration is mutual. Involvement with adolescent dating violence has serious physical and psychological health consequences, and in order to combat this social phenomenon, effective prevention programs are needed. The present study discusses key characteristics of school-based prevention programs that have been shown to be effective, as well as looks specifically at one such prevention program called BLOOM for Healthy Relationships™. The researcher in this study originally set out to conduct a program evaluation of BLOOM, but encountered several obstacles with the approval process that prevented the evaluation from being completed in the available time frame. This report is now framed as a case study that will discuss the necessary resources for preparing to conduct a program evaluation, describe the obstacles encountered in the approval process and make suggestions for future strategies to complete program evaluations of BLOOM.

Description
This dissertation used an evolutionary approach to examine the antecedents and outcomes to early pubertal development in girls in four major ethnic groups (i.e., European American, African American, Hispanic American, and Asian American). In the first study, logistic regressions were conducted to investigate the links between socioeconomic status (SES), parenting behaviors, and father absence to pubertal development across and within ethnic groups. SES and father absence predicted earlier pubertal development among European, African, and Hispanic Americans but not for Asian Americans. In the second study, growth curves were estimated for sexual outcomes across ethnic groups. Early developing European and African American girls had higher levels of sexual risk and pregnancy into adulthood. Puberty did not predict outcomes for Hispanic and Asian American girls. Overall, the findings from both studies revealed the importance of investigating childhood environmental contexts, puberty, and sexual health outcomes using an evolutionary perspective.

Description
Identity theorists have emphasized the importance of integration across identity domains for psychosocial well-being. There remains little research, however, on associations across identity domains, group differences across identity profiles, and the joint association of multiple identity domains with academic outcomes. This dissertation includes two studies that address these limitations in the identity literature. Study 1, examined the ego-social identity profiles that emerged from ethnic identity exploration and commitment, American identity exploration and commitment, and ego identity integration and confusion among an ethnically diverse sample of emerging adults using latent profile analysis (N = 8,717). Results suggested that an eight-profile solution was the best fit for the data. The profiles demonstrated differences in identity status and salience across identity domains. Significant ethnic, sex, nativity, and age differences were identified in ego-social identity membership. Study 2 focused on the ego-social identity profiles that emerged from the same identity domains among biethnic college students of Latino and European American heritage (N = 401) and how these profiles differed as a function of preferred ethnic label. The association of ego-social identity profile with academic achievement and the moderation by university ethnic composition were examined. Results indicated that a two-profile solution was the best fit to the data in which one profile included participants with general identity achievement across identity domains and one profile included individuals who were approaching the identity formation process in each domain. Ego-social identity profile membership did not differ based on preferred ethnic label. Individuals who had a more integrated identity across domains had higher college grades. University ethnic composition did not significantly moderate this association. Taken together, these two studies highlight the intricacies of identity formation that are overlooked when integration across identity domains is not considered.

Description
The Paradise Valley Family Resource Center (PVFRC) is a not for profit, community based organization funded by First Things First and a part of the Paradise Valley Unified School District (PVUSD) in Phoenix, Arizona. The mission of this organization is to connect and strengthen families with children from birth to five years old in the Phoenix valley. The PVFRC longed to be more cognizant of what the needs of the community they serve are, and how they, as an organization, can administer programs of value to the community. Hence, the PVFRC entered a partnership with the Community Action Research Experiences (CARE) program at Arizona State University to develop a research proposal to improve their effectiveness and efficiency at achieving their mission. The purpose of this research project was to identify and evaluate the needs of the families with children ages birth to five within the community, to improve upon existing programs and services or to implement new programs, and to discover more effective modes of awareness and advertisement to the community about the programs and services the PVFRC provides. The main research questions of the experiment included asking participants about what programs and services they need, wish, or want to exist at the PVFRC, what barriers or gaps they see or experience regarding attending the PVFRC, how did participants learn about the PVFRC, and what are the best ways to contact families in their community. The methods of the research included conducting focus group interviews with families who utilize the programs and services at the PVFRC and with early childhood professionals in the Paradise Valley Unified School District (PVUSD), which included social workers and preschool teachers. A total of 25 participants were interviewed (10 families, 6 social workers, and 9 preschool teachers) and responses from the interviews were coded by the researcher. The results of the research was that the PVFRC is meeting many needs and current families are satisfied, participants desire some changes to current programs and services, and the best modes of advertisement and awareness were "word of mouth" and the internet. It was recommended that in order to better achieve their mission, it is advised that the PVFRC make appropriate changes to programs and services as suggested by the participants, connect with mom's or parents groups in the community, collaborate with preschool teachers on the front line, and increase their online presence through the use of social media and their website.

Description
The Community Action Research Experiences (CARE) program collaborated with Singleton Moms, a local non-profit organization that provides financial, psychological, and social support services to single parents with cancer. The purpose of this action research project was to assess the volunteer program at Singleton Moms. Both past and present Singleton Moms' volunteers (N = 123; 87.0% female) completed an online survey assessing their motivation for volunteering and their satisfaction with the organization. A mixed ANOVA was conducted to identify the most important motivation and satisfaction domains and to see if the findings depended on whether the volunteers were current or past volunteers. For the motivation assessment, results indicated that the volunteers rate the cancer specific and moral/human kindness domains as the strongest reasons for motivating them to volunteer at Singleton Moms. In addition, results revealed that the social connection motivation domain was the only domain with differences between the ratings of the past and present volunteers. For the satisfaction assessment, results indicated that the volunteers rate the organizational climate domain as the most fulfilled area of satisfaction within the Singleton Moms' volunteer program. It was also revealed that there were no significant differences between the ratings of the past and present volunteers among all satisfaction domains. Both the quantitative and qualitative findings suggest that Singleton Moms' implications for action may include: 1) a volunteer database audit, 2) streamlining communications, 3) variability in volunteer times, and 4) bolstering volunteer motivation. Implementing some of these actions may help Singleton Moms increase volunteer motivation and satisfaction and thus create a more effective volunteer program. Ultimately, this may encourage volunteers to continue their services at Singleton Moms and thus help Singleton Moms expand their support programs and assist additional families.
