Relationship Between Self-Silencing And Self-Neglect Behaviors And Disordered Eating And Stigma Toward Seeking Behavioral Health Support Among Black Women Who Adopt The Superwoman Schema, Veanda Hemphill

Walden Dissertations and Doctoral Studies

Self-silencing and self-neglect behaviors, key dimensions of the superwoman schema (SWS), function as protective coping mechanisms in response to psychosocial stressors. However, these behaviors often perpetuate self-sacrifice, leading to an increased risk of physical and mental health decline. The purpose of this quantitative correlational study was to examine the relationship between self-silencing and self-neglect behaviors (independent variables) and disordered eating and stigma toward seeking support from behavioral health services (dependent variables) among Black women who adopt the SWS. The theoretical and conceptual frameworks of silencing the self and intersectionality guided this study. The 78 participants who self-identified as Black and …

Social Comfort And Attractiveness Perception: Impact Of Prosthetics, Physical Disability And Comfort Distance On Interpersonal Interactions, Farid Pazhoohi, Samantha Wing, Alan Kingstone Feb 2025

Social Comfort And Attractiveness Perception: Impact Of Prosthetics, Physical Disability And Comfort Distance On Interpersonal Interactions, Farid Pazhoohi, Samantha Wing, Alan Kingstone

School of Psychology

Derived from the disease-avoidance model is the hypothesis that people may direct negative cognitive and behavioural responses towards individuals with physical disfiguring conditions, including physical disabilities. According to the behavioral immune system, physical disability—a non-contagious physical disfigurement—may falsely activate cognitive disease-avoidance processes, resulting in prejudicial or negative responses toward individuals with physical disabilities. For the first time this hypothesis is put to the test by investigating whether ratings of attractiveness and comfort for a social interaction vary systematically with physical disability (Studies 1 and 2). In addition, we tested whether these ratings were associated with individual differences in pathogen disgust …

Influence Of Oil Density On Self-Propelled Motion Of Belousov-Zhabotinsky Reaction Droplet, Vivek Bharat Meshram, Anupama Sebastian, Puthiyapurayil Sibeesh, T K Shajahan

Northeast Journal of Complex Systems (NEJCS)

Belousov-Zhabotinsky reaction serves as an example of the nonlinear chemical oscillator in which the reacting substance undergoes sequential oxidation and reduction. A droplet containing the BZ reaction, when placed within the oily environment, can self-propel. In this experimental work, we explore the effect of oil medium density on the BZ reaction droplet dynamics. In an oil medium with lower density, the BZ droplet exhibits higher speed and effective diffusivity but a shorter lifetime. Both the distance and speed of the droplet initially increase with droplet volume. However, beyond a critical volume, the distance decreases while the speed stays constant. Interestingly, …

Architecting A More Gender-Inclusive Curriculum For Graduate Leadership Education, Galen J. Talis

Libraries

Graduate leadership education is an important context for increasing gender-inclusivity. Incoming students are increasingly likely to support an all-gender approach; transgender and nonbinary graduate students report safety concerns on campus; and leadership scholars have identified serious discrimination against trans and nonbinary employees in the workplace as well as the need for greater gender-inclusivity in leadership education. Cis women and men are more widely recognized as gender-diverse, whether due to intersections with other identities or due to within-gender complexity. Yet researchers often fail to identify a gender theory when researching gender and leadership, most commonly assume a gender-binary frame, and do …

Powering modern nanowatt sensors from omnipresent low-level kinetic energy: This study investigates the power levels produced by a varying-capacitance kinetic energy harvesting system. A model system consisting of a uniformly driven rotating capacitor was built to develop an accurate output power performance model. We found a quantitative linear relationship between the rectified output current and the input applied bias voltage, driving frequency, and capacitance variation. We also demonstrate that our variable capacitor system is equivalent to a fixed capacitor driven with an alternating current power source. Both the fixed-capacitance and varying-capacitance energy harvesting systems recharge a three-volt battery, which in …
