Intermittence For Humans Spreading 45,000 Years Ago: From Eurasia To The Americas, J. C. Flores

Human Biology Open Access Pre-Prints

From northeastern-Eurasia to the Americas, a three stage spread of Modern Humans is considered through large scale intermittence (exploitation/relocation). Conceptually, this work supports intermittence as a real strategy for colonization of new habitats. For the northeastern Eurasia travel, the first stage, we adapt our model to archaeological dates determining the diffusion coefficient (exploitation phase) as D=299.44 [km²/yr] and the velocity parameter (relocation phase) as v_o=4.8944 [km/yr]. The relative phaseweight (≈ 0.46), between both kind of motions, is consistent with a moderate biological population rate (r'≈ 0.0046 [1/yrs]). The second stage is related to population …

Understanding Less Than Nothing: Children's Neural Response To Negative Numbers Shifts Across Age And Accuracy, Margaret M. Gullick, George Wolford

Dartmouth Scholarship

We examined the brain activity underlying the development of our understanding of negative numbers, which are amounts lacking direct physical counterparts. Children performed a paired comparison task with positive and negative numbers during an fMRI session. As previously shown in adults, both pre-instruction fifth-graders and post-instruction seventh-graders demonstrated typical behavioral and neural distance effects to negative numbers, where response times and parietal and frontal activity increased as comparison distance decreased. We then determined the factors impacting the distance effect in each age group. Behaviorally, the fifth-grader distance effect for negatives was significantly predicted only by positive comparison accuracy, indicating that …

An Examination Of The Relationship Between Exposure To Violence In The Home And Attachment Characteristics Among Youth With Sexually Harmful Bahaviors, Talia J. Jackson

Theses, Dissertations, and Projects

The aim of this study was to investigate the relationship between exposure to violence in the home and attachment characteristics in youth with sexually harmful behaviors. In this study the following was investigated: whether maternal/paternal attachment plays a mediating role in the relationship between exposure to violence in the home (both experienced and witnessed) and adolescent sexual/non-sexual offending. The sample size was 296 male youth with sexually harmful behaviors placed in six residential treatment facilities. Four mediation models were used to examine attachment and exposure to violence in the home in youth with sexually harmful behaviors. Results showed no support …

"What Are You, Anyway?" : How Parents Help Their Multiracial Children Live In A World Of Singular Racial Categories, Chloe A. Jhangiani

Theses, Dissertations, and Projects

The growing numbers and visibility of multiracial individuals in the United States necessitate that social workers, parents, and researchers understand the unique strengths and stressors multiracial individuals face. This study qualitative study explored the ways in which parents racially socialized their multiracial children. Fifty-three multiracial adults completed online surveys about their childhood experiences with racism, monoracism and racial socialization. Participants wrote about how their parents handled racial socialization (or how they did not) in a variety of ways: by embracing racial stereotypes, denying the existence of race and racism, giving general pride but no discussion of race, teaching about racism, …

Crossover Of Organizational Commitment, Rebecca A. Bull Schaefer, Stephen G. Green, Mahima Saxena, Howard M. Weiss, Shelly M. Macdermid Wadsworth

Psychology Faculty Publications

Spousal commitment toward an employee's organization is a little-studied construct that deserves attention because his or her spouse may influence the employee's assessments of organizational commitment and turnover intentions. Using 186 couples, this study investigated spousal influence on U.S. military members’ organizational commitment and their decisions to reenlist. Results of a structural equation model analysis indicate that indirect mechanisms of crossover (e.g., positive emotions displayed by the spouse during discussions of reenlistment) facilitated the positive relationships between the organizational commitment of military spouses and members. Findings and discussion contribute to the fields of organizational commitment and crossover, and we conclude …

A Case Study Of Gender Neutral Policies In University Housing, Josh Chave

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Gender neutral housing is an innovative new policy being developed in colleges around the country. One reason to create these policies is an attempt to meet the unique needs and challenges of lesbian, gay, bisexual, and transgender students. As the number of gender neutral housing policies in the United States continues to rise, research has been slow to meet the growing demand for empirical data on gender neutral housing.

The dissertation presented a case study of one institution. Interviews and focus groups were conducted with administrators, gender neutral housing committee members, residence life staff, and students. This dissertation examined the …

Stigma, Race And Mental Illness : African-American Clinicians' Perceptions Of How These Factors Influence Help-Seeking Behaviors In African Americans, Rabi'ah S. Jamar

Theses, Dissertations, and Projects

They also shared their perceptions of African American attitudes, based upon client interactions, towards mental illness and whether a change has occurred within the past 5-10 years; identifiable stigmas within the African American community; inhibitors to help-seeking behaviors; variables that influences help-seeking behaviors; and their recommendations for improving African Americans' comfort with disclosure within the therapeutic setting. …

Patterns Of Senescence In Human Cardiovascular Fitness: Vo2 Max In Subsistence And Industrialized Populations, Anne C. Pisor, Michael Gurven, Aaron D. Blackwell, Hillard Kaplan, Gandhi Yetish

ESI Publications

Objectives—This study explores whether cardiovascular fitness levels and senescent decline are similar in the Tsimane of Bolivia and Canadians, as well as other subsistence and industrialized populations. Among Tsimane, we examine whether morbidity predicts lower levels and faster decline of cardiovascular fitness, or whether their lifestyle (e.g., high physical activity) promotes high levels and slow decline. Alternatively, high activity levels and morbidity might counterbalance such that Tsimane fitness levels and decline are similar to those in industrialized populations.

Methods—Maximal oxygen uptake (VO2max) was estimated using a step test heart rate method for 701 participants. We compared these estimates …

Myelin Basic Protein And Glial Fibrillary Acidic Protein Antibodies In Autism, Edward Stevenson, Dr. Erin Bigler

Journal of Undergraduate Research

Autism is a developmental disorder. There has been an increasing trend in the diagnosis of autism in the past 15 years. After years of research there is still little agreement as to the causes of autism. It has been hypothesized that autistics could be the result of the body’s immune system attacking the brain through cytotoxicity and antibody mediated responses.2 Studies between immune factors and autism have had some interesting results, yet due to the complexities of the central nervous system and immune system, solid conclusions have not been reached.

While working in this role I investigated and gathered details of the Somali Bantu women’s daily experiences involving urban immigrant acculturation and assimilation.

The World Vs. The United States How The International Community Defied A Superpower To Create The International Criminal Court, Anna Sanders, Dr. Darren Hawkins

Journal of Undergraduate Research

The International Criminal Court has been an item of some debate both here in the United States and in the international community. The United States opposition and the subsequent creation of a supranational body without it’s support provide an interesting case for studying international organizations. It is puzzling to consider: why would nations go against the wishes of the world superpower and create a court with unparalleled supranational authority? What influences negotiating positions and how did these change throughout the drafting process? We hypothesized that nations’ positions were influenced by their dependence on other nations. More plainly, we supposed that …

Education In Rural Mexico: What Stops Students?, Jared A. Wilkerson, Dr. Harold Miller

Journal of Undergraduate Research

Providing regular education in rural Mexico has been a focus for the Mexican government for the last few decades. Even twenty years ago, many teachers were quite unwilling to visit rural areas, where the facilities and transportation were far under par. By the beginning of this decade, however, kindergarten and elementary schools had reached even the most remote parts of the country, with middle schools and high schools increasingly accessible to all potential students. Seeing the still-low rates of rural student matriculation, and especially noting the extremely low rates of male education, I wondered what inhibited youth from finishing, or …

Alleged Rape Perception And Function Of Ambivalent Sexism, Adriane Queiroz, Dr. Niwako Yamawaki

Journal of Undergraduate Research

The purpose of this study was to discover how a perceived power difference between rape victim and perpetrator influence external observers’ rape perception, or more specifically, to investigate the effects of a rapist’s power status on rape perceptions, such as minimization of the seriousness of rape, blaming victim, and excusing the perpetrator. This study also explored the moderating role of ambivalent sexism to explain the effects of power on rape perceptions.

Effects Of The Neurosteroid Pregnenolone Sulfate On Hippocampal Physiology, Marc Jones, Dr. Scott Steffensen

Journal of Undergraduate Research

Several recent studies have established a role for estrogens in ameliorating specific neurodegenerative disorders, mainly those associated with the cholinergic neurons of the basal forebrain and their targets in the cortex and hippocampus. We have previously demonstrated that endogenous and exogenous application of the neurosteroid dehydroepiandrosterone sulfate (DHEAS) markedly reduces GABA-mediated recurrent inhibition and synchronizes hippocampal unit activity to theta rhythm. In this study, I evaluated the role of muscarinic receptors in mediating the effects of the GABA-modulating neurosteroid, pregnenolone sulfate (PREGS) on monosynaptic evoked potential responses, paired-pulse inhibition, paired-pulse facilitation and GABA interneuron activity in the dentate gyrus and …

Adverse Selection In The Market For Health Insurance, Jonathan Hall, Dr. Mark Showalter

Journal of Undergraduate Research

The presence and severity of adverse selection in the market for health insurance has profound implications for public policy. Adverse selection occurs when individuals who are higher risk than observationally equivalent individuals purchase more insurance. Adverse selection can be used to argue in favor of nationalized health care, and at the same time suggests it that regulation simply makes problems worse. Due to the importance of this question, researchers from a wide variety of fields—public health, economics, insurance, law, human resources and medicine, to name a few—have contributed to the literature on adverse selection. Unfortunately, most researchers seldom cross disciplinary …

Censored Regression With Flexible Distributions, Randall Lewis, Dr. James Mcdonald

Journal of Undergraduate Research

In the field of economics, the estimation of causal relationships is fundamental. The economist formulates a model or mechanism through which human behavior affects outcomes. Then, by using real-world data, economists can estimate these relationships. For example, one simple relationship that has been a subject of study is the causal effect of education on income. Whereas in other fields correlation is typically the object of interest, in economics, the actual quantitative effect on outcomes of changing a causal variable, such as years of education, is of interest.

The Economics Of Childhood Obesity, Stephen Done, Dr. Eric Eide

Journal of Undergraduate Research

Over the past three decades, there has been a significant increase in the percentage of obese persons in the United States. Among adults, rates have more than doubled, while nearly tripling for children over the same period (Anderson, Butcher, & Levine, 2003). Now the second leading cause of death in the United States, obesity contributes to heart disease, stroke, high blood pressure, diabetes, depression, and many types of cancers (Rashad, Grossman, & Chou, 2005). Economic costs, in the form of health care and lost productivity, amounted to $12.7 billion in 1994 alone (Tomson, Edelsburg, Kinsey, & Oster, 1998). It is …

Primary Sources On C. E. Kelsey And The Northern California Indian Association, Larisa K. Miller

Journal of Western Archives

This article provides a brief history of and identifies primary sources on C. E. Kelsey and the Northern California Indian Association, which brought federal support to the nonreservation Indians of northern California in the early 1900s. Kelsey is a frequently mentioned but largely unknown figure in the unique history of Indian-white relations in California. As an officer of the Northern California Indian Association (NCIA) and special agent for the Indian Office he altered the landscape for California Indians. Because there is no corpus of Kelsey's personal papers, NCIA records, or government records, he remains largely unknown, to the point that …
