Homocysteine And Csrp-3 Protein In Migrating Neural Crest Cells: A Quantitative And Qualitative Confocal Microscopy Study, Allysan R. White

Dissertations and Theses @ UNI

Congenital heart defects are one of the leading causes of infant death. High maternal blood serum levels of the amino acid homocysteine and the frequency of heart defects are correlated, but the immediate cause is unknown. During early embryonic development, a distinctive population of cells arises dorsally as the neural tube closes, forming the brain and spinal cord. These are the neural crest cells, which play a crucial role in the development of the nervous system, head skeletal, certain endocrine and connective tissues, and, notably, the heart’s outflow region. These migratory cells will follow specific pathways and respond to signals …

Labeling Of Religious Non-Believers: The Effect Of The "Atheist" Title On Moral Judgments About Non-Theists, Brock C. Rozich

Dissertations and Theses @ UNI

Prior research indicates that how concepts are described impacts our beliefs about the subject itself. For example, when the term “welfare” (instead of “help for the poor”) is used to ask people whether assistance should be increased in times of economic hardship, support is lower (Smith, 1987). My research question centers on whether or not this effect would carry over to the area of religion and the use of the terms “atheist” or “those with no religious beliefs.” Participants in the current studies were presented with a vignette about a student who was labeled as an atheist, as having no …

The Effects Of Control Threat On Women's Acceptance Of Benevolent Sexism And Traditional Gender Roles, Zheng Li

Dissertations and Theses @ UNI

System Justification Theory (SJT; Jost & Banaji, 1994) predicts that people tend to accept and endorse the current socioeconomic and political arrangement when they feel threatened. Based on SJT, women should support traditional gender roles and benevolent sexism when they feel threatened because these system-justifying beliefs can mitigate anxiety and distress elicited by existential threats. In the current study, female participants’ responses to a control threat were measured by an author-generated scale on attitudes toward traditional gender roles for women and Benevolent Sexism Scale (Glick & Fiske, 1996). In a community sample (but not in a student sample), participants whose …
