Internalized Gender Role Stereotypes Within Young Women And The Presentation Of Somatic Symptomatology Of Major Depressive Disorder, Michelle Miselevich

Dissertations and Theses

Evidence suggests that two distinct disorders are currently being diagnosed as depression. One, somatic depression, involves depression plus several somatic symptoms while the other, pure depression, involves depression without as much somatic symptomatology. Somatic depression has been hypothesized to afflict women who view themselves non traditionally and thus do not agree with traditional stereotypes of women. Measures of agreement with negative stereotypes of members of their own group have been found in several groups to be positively related to depression. This may apply among women to pure depression. Thus, women who exhibit pure depression are hypothesized to exhibit agreement with …

Dissertations and Theses

Climate change poses a potentially unique generational crisis, as it threatens the viability of the very world that the current adolescent generation stands to inherit. While some studies have begun to appreciate the specific experience of adolescents as it pertains to climate change, they attend to young people’s behavior or self-reported feelings. The present study aims to employ psychoanalytic constructs, with attention to the unconscious determinants of psychic life and behavior, in an empirical examination of this topic, and to introduce a level of sensitivity to the vicissitudes of the adolescent period that have not previously been addressed in the …

Early Adversity, Emotion Regulation, Object Relational Functioning, And The Moderating Effect Of Gender Identity: A Community Sample Study, Victoria Schilder

Dissertations and Theses

Introduction: Clinical and social psychological literature have long demonstrated group status, culture, and social support as equally integral and influential factors which contribute directly both to the quality of one’s lived experience, and to the development and experience of one’s sense of identity or selfness. For example, acceptable norms regarding behavior, dress, and emotional experience – particularly when an individual does not live up to societal standards – have been demonstrated to contribute to deleterious internalizations surrounding self-confidence, self-worth, and self-esteem. More specifically, the social and cultural implications of being identified as “female” versus “male” have been found to be …

Immigrant Risk, Self-Discontinuity, And The Role Of Nostalgia, Leila Talhouk

Dissertations and Theses

Background: There are conflicting theories and data about immigrants’ health in the host country (e.g., immigrant risk vs. paradox), which have encouraged researchers to examine more nuanced factors related to immigration to clarify these inconsistencies. This two-part study aimed to shed light on these discrepancies by investigating psychoanalytic concepts that have not yet been empirically tested. The study focuses on immigrant self-discontinuity, a migration- induced disruption in one’s sense of self-sameness and unconscious sense of going-on-being, manifesting in moments of disorientation, disorganization, or dissociative-like experiences. There is no adequate instrument to measure this construct; as such, Part 1 of the …

Auditory Processing Deficits In Msh2-Ko Mice Are Linked To Aberrant Inhibitory Neuron Function In The Thalamic Reticular Nucleus, Sadia N. Rahman

Dissertations and Theses

DNA repair mechanisms are crucial for both cellular development and function. One highly conserved DNA repair factor is Mut-S Homolog 2 (Msh2), which corrects base-base mismatches and insertion/deletion loops. In humans, defects in this repair pathway are linked to diseases that have severe neurological pathologies. These include Lynch syndrome, Huntington’s disease and demyelination of the corpus callosum. The fundamental role of Msh2 in brain function is unknown. Using an Msh2^-/- mouse model we began an exploration of its impact on the processing of sensory information, a crucial function to an animal’s survival. The goal of this …

Fine Characterization Of Leafing Phenology In The Brazilian Atlantic Forest By Optical And Microwave Remote Sensing, James B. Bell

Dissertations and Theses

Tropical forests provide important ecosystem functions in the global biosphere, but they remain among the most poorly understood elements of land surface models, especially with regard to their seasonal dynamics. For instance, in seasonally dry forests, the pattern of the annual green-up in their canopies closely follows annual patterns of rainfall. The same, however, does not occur in wet forest canopies which are dominated by evergreen trees. In the latter, water is not scarce enough to limit leaf photosynthetic function. Canopy leafing phenology in these forests is therefore poorly characterized by optical remote sensing methods which are not sensitive to …

The Nexus Of Climate Change And Human Rights: An Examination Of How Social, Political, And Environmental Impacts Of Climate Change Jeopardize The Protection Of Human Rights In The African Sahel, Camden R. Malone

Dissertations and Theses

Climate change is a threat multiplier by its driving forces of environmental stress and scarcity. In the developing world, countries are hit hardest and most frequently by the effects of climate change, such as severe floods, droughts, and desertification. In this thesis, I argue that existing models for the umbrella-term of climate-security underemphasize dimensions of human security through exclusion of HR violations linked to climate such as subjection to food/water stress, compromised health, displacement, and violent conflict. Therefore, the climate-security paradigm should be recast to pay closer attention to its consequences related to human rights protection, which I refer to …

Unity Against Adversity: Examining The Moderating Effect Of A Sense Of Community Between Discrimination And Discrimination-Related Distress Among Racial And Ethnic Minoritized Adults, Kimberly Velazquez

Dissertations and Theses

Background: Racial and ethnic minoritized populations are significantly more likely to develop mental health conditions, such as depression, anxiety, and posttraumatic stress disorder, than White populations. Some of the predominant causes are rooted in the impact of discrimination, and other social determinants of health (SDOH), including adverse experiences. Studies found that discrimination can lead to a distinct form of anxiety described as discrimination-related distress, which has a higher negative association with poor mental health symptoms. It has been suggested that having a strong sense of community (SOC) –a collective sentiment shared by community members regarding their membership, feelings of belonging, …

Assessment Of Material Properties In Bone Surrounding Microdamage, Niovi Dollas

Dissertations and Theses

Bisphosphonates [BPs] are the mainstay for osteoporosis treatment. They suppress bone resorption/remodeling, preventing bone loss. However, BPs also suppress the beneficial bone remodeling that replaces microscopically damaged bone that occurs from normal mechanical wear-and-tear or fatigue, leading to impaired tissue material properties and in some instances atypical femoral fractures.

In these studies, we assessed the effects of acute fatigue, fatigue induced remodeling, and fatigue microdamage with remodeling suppression using the clinical BP, alendronate [ALN], on local bone material properties. Studies were performed on cortical bone sections from rat ulnae into which fatigue damage had been introduced in vivo. Rat …
