Empathizing-Systemizing Cognitive Styles: Effects Of Sex And Academic Degree, Rachel Kidron, Leon Kaganovskiy, Simon Baron-Cohen

Department of Behavioral Science Publications and Research

This study tests if the drives to empathize (E) and systemize (S), measured by the Systemizing Quotient-Revised (SQ-R) and Empathy Quotient (EQ), show effects of sex and academic degree. The responses of 419 students from the Humanities and the Physical Sciences were analyzed in terms of the E-S theory predictions. Results confirm that there is an interaction between sex, degree and the drive to empathize relative to systemize. Female students in the Humanities on average had a stronger drive to empathize than to systemize in comparison to males in the Humanities. Male students in the Sciences on average had a …

From Research-To-Practice: An Adaptation And Dissemination Of The Compass Program For Home Care Workers, Ryan Olson, Jennifer Hess, Kelsey N. Parker, Sharon V. Thompson, Anjali Rameshbabu, Kristy Luther Rhoten, Miguel Marino

OHSU-PSU School of Public Health Faculty Publications and Presentations

The COMmunity of Practice And Safety Support (COMPASS) program was developed to prevent injuries and advance the health and well-being of home care workers. The program integrates elements of peer-led social support groups with scripted team-based programs to help workers learn together, solve problems, set goals, make changes, and enrich their supportive professional network. After a successful pilot study and randomized controlled trial, COMPASS was adapted for the Oregon Home Care Commission’s training system for statewide dissemination. The adapted program included fewer total meetings (7 versus 13), an accelerated meeting schedule (every two weeks versus monthly), and a range of …

What Does The Fos Say? Using Fos-Based Approaches To Understand The Contribution Of Stress To Substance Use Disorders, Jayme R. Mcreynolds, John P. Christianson, Jordan M. Blacktop, John Mantsch

Biomedical Sciences Faculty Research and Publications

Despite extensive research efforts, drug addiction persists as a largely unmet medical need. Perhaps the biggest challenge for treating addiction is the high rate of recidivism. While many factors can promote relapse in abstinent drug users, the contribution of stress is particularly problematic, as stress is uncontrollable and pervasive in the lives of those struggling with addiction. Thus, understanding the neurocircuitry that underlies the influence of stress on drug seeking is critical for guiding treatment. Preclinical research aimed at defining this neurocircuitry has, in part, relied upon the use of experimental approaches that allow visualization of cellular and circuit activity …

17Β-Estradiol Potentiates The Reinstatement Of Cocaine Seeking In Female Rats: Role Of The Prelimbic Prefrontal Cortex And Cannabinoid Type-1 Receptors, Elizabeth M. Doncheck, Luke A. Urbanik, Margot C. Debaker, Laura M. Barron, Gage T. Liddiard, Jennifer J. Tuscher, Karyn M. Frick, Cecilia J. Hillard, John Mantsch

Biomedical Sciences Faculty Research and Publications

Clinical observations imply that female cocaine addicts experience enhanced relapse vulnerability compared with males, an effect tied to elevated estrogen phases of the ovarian hormone cycle. Although estrogens can enhance drug-seeking behavior, they do not directly induce reinstatement on their own. To model this phenomenon, we tested whether an estrogen could augment drug-seeking behavior in response to an ordinarily subthreshold reinstatement trigger. Following cocaine self-administration and extinction, female rats were ovariectomized to isolate estrogen effects on reinstatement. Although neither peak proestrus levels of the primary estrogen 17β-estradiol (E2; 10 μg/kg, i.p., 1-h pretreatment) nor a subthreshold cocaine dose …

Assessment Of Peripheral Bdnf Levels Over 30 Days, Sally Hang

Cal Poly Humboldt theses and projects

Brain health, and the benefits of exercise have been linked to the biological signaling molecule called brain-derived neurotrophic factor (BDNF). Animal and human studies have provided some support for physical exercise as a mechanism for increasing BDNF levels. However, results have been inconsistent, which may be attributed in part to incomplete information about normal variation in circulating peripheral BDNF levels. This investigation examined capillary-drawn whole blood samples from nine healthy adult participants over 30 days with the goal of documenting variability in resting BDNF levels and changes that may be attributed to physical exercise. It was hypothesized that BDNF concentrations …

Investigating Differing Degrees Of Foxo3a Expression In Adult Neural Stem Cells Between Age Groups In Zebrafish, Francis G. Bacik

Cal Poly Humboldt theses and projects

One factor influencing organismal longevity is the activity of transcription factors of the “fork head domain” family, otherwise known as “Forkhead box” (Fox) proteins. Studies of the four isoforms of the “O” subclass of Fox proteins found in human genes have revealed a direct relationship between FoxO3a-dependent gene expression and the conservation of neural stem cell (NSC) in the adult brain, specifically in the subgranular zone of the dentate gyrus in the hippocampus and the subventricular zone of the cortex. This transcription factor has also been shown to regulate apoptosis in nervous tissue during embryonic development in zebrafish. The current …

Effects Of A Peer-Assisted Physical Activity Program On Depression And Anxiety In College Students, Crystal Stroud

Cal Poly Humboldt theses and projects

The purpose of this qualitative study was to examine the effects of a peer-assisted, self-selected physical activity program on depression and anxiety in students at a four-year university, and to explore the various possible mechanisms by which depression and anxiety were affected. These mechanisms included physical activity, self-efficacy, relatedness, competence, and autonomy. A secondary purpose was to examine the benefits of participation for the physical activity buddies who provided the peer-support. In-depth interviews were conducted with three program participants with depression and/or anxiety, six physical activity buddies who supported the participants, and three referring professional healthcare providers. A qualitative data …

Differences In Hair Significance Among Black And White Women: An Exploratory Study On Black Hair, Yasmine S. Keen

Cal Poly Humboldt theses and projects

In Western culture, standards of beauty are often based on European characteristics that Black women are inherently unable to meet. African American history and anecdotal accounts suggest that hair in particular can have a significant impact on the perception and body image of Black women, though whether that impact is positive or negative is not clear. The current study takes a quantitative approach to examining women’s relationship with their hair. Black women (n = 146) and White women (n = 1,116) participated in an anonymous online survey regarding time devoted to hair maintenance, money spent on hair upkeep, …

The Effects Of Descending Resistance Sets Compared To Constant Resistance Sets On The Volume Completed During A High Intensity Free Weight Back Squat Exercise, Jason E. Meyer

Cal Poly Humboldt theses and projects

Improving anabolic hormone production is an important training adaptation in resistance training; however, no previous research has developed optimized descending resistance sets to increase training volume. The purpose of this research was to compare two different loading protocols of constant resistance sets (CRS) and descending resistance sets (DRS) on the free weight back squat. Eleven resistance trained male participants (mean ± SD, age = 22 ± 3 yr, and back squat 1RM ratio (1RM/body weight) = 1.65 ± 0.2) completed 4 experimental sessions over 2 weeks, during which 4 sets of the back squat were performed with 85% 1RM and …

Religion, Language, Gender, And Culture: Challenges Experienced By Saudi International Students In Humboldt County, Dafer Sahab Alqarni

Cal Poly Humboldt theses and projects

The effects of culture shock on individuals living abroad are well known. Less well known, however, are the specific experiences, needs, and challenges of Saudi Arabian students studying internationally, especially in Western nations. In this study, I used qualitative research to explore the needs and difficulties of Saudi international students in Humboldt County and at Humboldt State University (HSU). Using semi-structured interviews with eight participants, diversified by gender and marital status, I provide a holistic view of HSU Saudi international students’ experiences and challenges which could help to understand Saudi students’ experiences abroad generally, and in Humboldt County specifically. I …

Hobby preferences have been shown to influence physical activity participation. PURPOSE: The purpose of this study is to examine the hobby preferences of children with ASD and determine if there are differences depending on the children’s physical activity level and the nature of their preferred activities. A secondary purpose is to describe the hobby preferences of children with ASD. METHODS: Participants include 98 nine-year-old children (with and without ASD) from the National Growing up …

The Entangled Student: Identity Control Theory And Student Identity, Joshua Smith

Cal Poly Humboldt theses and projects

This study examines the strengths and opportunities in applying the frame of Identity Control Theory (ICT) to understanding the first-year experiences of students in higher education. Through thirty-one semi-structured interviews with undergraduate and graduate students during their first term in the program of study, different components of the ICT model are explored and tested. Results indicate ICT is modestly effective in explaining the first term experience for these students, but could be enhanced through further development in the areas of identity connectedness, identity exploration and resources/resilience. Recommendations for higher education programming and suggestions for a potential research agenda for ICT …

Children's Mental Health Care Needs Assessment In Six Rural Northern California Counties, Brandi L. Goodspeed

Cal Poly Humboldt theses and projects

Mental health problems affect millions of children and adolescents each year. Furthermore, the prevalence of these difficulties may be higher among children living in rural communities. Primary care providers are playing a larger role in the treatment of mental health challenges in youth. The present study examined the experiences and knowledge of rural parents and primary care providers regarding children’s mental health care.

While providers practicing in six counties were invited, all respondents (N = 19) practiced in Humboldt County. Parents were recruited through schools which agreed to distribute the survey. Ten principals in four counties agreed, including Del …

The Positive Effects On Attitude Among High School Students Towards Students With Autism Spectrum Disorder, Mario Castillo-Urbina

Cal Poly Humboldt theses and projects

Inclusion in the classroom requires that the local education agency provide services (i.e., direct, related) to support each student’s needs. The philosophy guiding inclusion is that these services will allow each student to keep pace or catch-up with his or her typically developing peers (Elkins, Van Kraayenoord, & Jobling, 2003). Students’ attitudes towards their peers with disabilities have been researched and reported through the years however, little work has examined these attitudes in a physical education setting (Archie & Sherrill, 1989; Block & Malloy, 1998; Block & Zeman, 1996; Tripp, French, & Sherrill, 1995). Researchers have reported that individuals avoid …

We Break Our Bodies To Save Our Souls: Identity Construction Through The Participation In Flat Track Roller Derby, Torisha Stone

Cal Poly Humboldt theses and projects

While sociology of sport has been growing steadily over the last few decades, with an increased focus on how sports participation allow for active identity construction, research on roller derby is incredibly limited. I argue that research on roller derby provides an important window for understanding gendered sports construction and participation. Derby also provides a space where identities are created through performance in addition to the creation of unique personas or in some cases primary identities. In this study, I conducted 15 semi-structured open ended interviews using non-probability and snowball sampling techniques of a rural roller derby league as well …

Using Functional Infrared Thermal Imaging To Measure Stress Responses, Julia Tenaya Kandus

Cal Poly Humboldt theses and projects

The stress response reflects a coordinated pattern of physiological changes that serves the adaptive function of increasing an organism’s ability to cope with situations that require action or defense. The changes in blood flow associated with the stress response may be detectable using the relatively new research technique of functional infrared thermal imaging (fITI). The present study was designed to determine the time-course and topography of temperature changes in human faces during the experience of a stressor. Infrared images were taken from 29 female participants while they completed the mental arithmetic component of the Trier Social Stress Test (TSST). Continuously …

Test Of Bpa's Estrogenic Effects On Brain Aromatase Expression, Neural Activity, And Locomotive Behavior In Zebrafish Larvae, Ryan J. Mcauley

Cal Poly Humboldt theses and projects

Bisphenol A (BPA) is a well-known endocrine disrupting chemical that mimics the effects of estrogens. Aromatase B (Cyp19a1b) is a brain-specific enzyme that converts testosterone to estrogen and is highly upregulated in response to estrogen receptor activation localized to radial glial cells. During embryonic zebrafish development, there is a small window of time denoted by an increase in neurogenesis and estrogen receptor activity. Previous studies have demonstrated that a low dose BPA exposure (0.1µM) during this window causes hyperlocomotion in larval zebrafish, yet no further explanation for this behavior change has been described. The purpose of this study was to …

Legacies Of Industrial Contamination: Voices Of Resistance In White Lake, Michigan, Elizabeth A. Revord

Cal Poly Humboldt theses and projects

This research presents a case study of resistance to contamination from three large chemical plants by activists in the communities of Montague and Whitehall located on White Lake, Michigan. Although clean-up efforts have met state and federal guidelines for brownfield and Superfund sites, the people and community of White Lake have continued to be vigilant regarding environmental protection and harbor many concerns regarding their future and redevelopment of sites that are likely still contaminated.

The connection to place and sense of community that the residents of White Lake honor is the foundation of their resistance. Using data collected from semi-structured …

Involvement And Campus Climate On The Academic Success Of Black College Students, Tyries Delemar

Cal Poly Humboldt theses and projects

There has been an increasing number of Black students entering into higher education, but they continue to have disparities in academic achievement when compared to White students. An institution's campus climate has been found to influence student success. This study seeks to examine the factor of campus climate, specifically negative campus racial climate (NCRC), as it relates to the GPA and university satisfaction of Black students at a rural institution. The study adds to the literature by exploring the degree to which involvement (Faculty (FOI) and Club/Organization Involvement (COI)) may act as a moderating force within the relationship.

Three surveys …

Researchers have reported a limited number of studies on best-practices to improve performances in the physical education setting for children with attention deficit hyperactivity disorder (ADHD; Verret, 2010). The purpose of this study was to provide an analysis of literature on the current teaching practices to improve student performance in the physical education environment for children with ADHD. The following databases SportsDiscus, PsychINFO, PsychARTICLES, PubMed/Medline, ProQuest, Child Development and Adolescent Studies, and ERIC from 1970 to 2017 were used for this literature search. Results from this investigation demonstrated no significant results in behavioral outcomes in aggression, anxiety/depression, attention, externalized/internalized problems, …

Chicana Feminist Participatory Action Research: Collaborative Environmental Justice In The Imperial Valley And The Identifying Violations Affecting Neighborhoods Community Development Project, Kristian Michelle Salgado

Cal Poly Humboldt theses and projects

In 2007 in Imperial County, a community-based organization called Comite Civico del Valle (CCV), along with the Department of Toxic Substances, and concerned residents, created the Identifying Violations Affecting Neighborhoods (IVAN). IVAN is a community-based environmental reporting and monitoring system that is built on the idea that residents are the most knowledgeable about their environment and therefore should have a place at the table alongside environmental regulation agencies. For more than a decade, this has allowed residents to better report environmental concerns. However, for many residents there is still a lack of knowledge about how to properly utilize the IVAN …

The 2016 Election: Conservative Female Voters Agentive, Adversarial And Resolutely Republican, Laura F. Benne Ms

Cal Poly Humboldt theses and projects

In the American General election of 2016, the political discourse in the popular media demonstrated a nationwide expectation that female voters and their allies would elect the first female head of state on election day. As the President and his administration assumed control, many of those who had expected a different electoral result expressed bewilderment after learning that 53% of white, female conservative women chose the Republican male candidate Donald Trump for President. Narratives critical of the voting behavior of conservative women were prevalent. This discourse was informed by a blame and shame paradigm of accusations ranging from racism, lack …

Out Of Sight, Out Of Mind: An Analysis Of Household Food Waste In Arcata, California, Jennifer Michelle Domareki

Cal Poly Humboldt theses and projects

A rising demand for healthy and sustainably grown food has become a trend of our time. However, there is dissonance in contemporary awareness about where food comes from and where it ultimately ends up. Globally, one third of all food produced is never used. In the United States alone, approximately 55 million tons of food is discarded each year (Venkat, 2012). This is problematic because food waste has environmental, economic and social costs associated with it. Organic materials accelerate anthropogenic climate changing greenhouse gas emissions by releasing methane as they decompose in landfills. In addition, unused food embodies and thus …

Does Developmental Task Disruption Mediate The Link Between Childhood Adversity And Psychopathy?, Kali C. Williams

Cal Poly Humboldt theses and projects

Research has linked adult psychopathy with abuse or neglect in childhood; however, less is known about how it relates to other adverse childhood experiences. The prevention of psychopathic traits may be possible if the issue is examined from a developmental psychopathology perspective, which attempts to understand how early experiences and disruptions in stage-salient tasks may contribute to pathological behavior. ACEs may disrupt the attachment bond between child and parent and continue to impact adult relational functioning, via cognitive templates of adult attachment styles and difficulties with emotion regulation.

This study examined whether ACEs were related to psychopathic trait scores in …

Sniffing Out Decomposition: Investigating The Reliability Of Human Remains Detection Dogs, Kristen Marie Nawn

Cal Poly Humboldt theses and projects

The purpose of this study was to investigate the reliability of trained Human Remains Detection (HRD) dogs in the field. HRD dogs are trained to locate deceased individuals, typically in conjunction with law enforcement agencies, by using their enhanced olfactory systems to detect scents that humans cannot. Limited research has been conducted on both the strengths and weaknesses of these dogs and their abilities to locate human remains. This study focused on one North Carolina based organization that trains HRD dogs. Data were collected by distributing surveys and by observing regularly scheduled training exercises conducted by the organization. The collected …

Listening To Our Graduate Students' Feedback: Graduate Student Exit And Alumni Surveys, Alison W. Hong-Novotney

Cal Poly Humboldt theses and projects

Student and alumni surveys have become some of the most widely-used methods of assessment of student learning in higher education. While the majority of literature on student surveys and assessment focuses on undergraduate students, this study looks specifically at why graduate student exit and alumni surveys can be valuable tools within a comprehensive assessment plan. Listening to the feedback of current and former graduate students, and then acting upon that feedback, is crucial for the engagement and success of this unique population of students who bring their particular strengths and needs to their educational experiences. This study examined how master’s …
