Child-Taking, Diane Marie Amann

Scholarly Works

A ruling group at times takes certain children from their community and then tries to remake them in its image. It tries to rid the child of undesired differences, in ethnicity or nationality, religion or politics, race or ancestry, culture or class. There are too many examples: the colonialist residential schools that forced settler cultures on Indigenous children; the military juntas that kidnapped dissidents’ children; and today’s reports of abductions amid crises like that in Syria. Too often nothing is done and the children are lost. But that may be changing, as the International Criminal Court is seeking to arrest …

In Or Out?: Understanding The Japanese Immigration Policymaking Process And The Sub-National Response To The Challenge Of Global Migration, Jeorge G. Alarcon Jr.

Journal Article

There is no comprehensive Japanese immigration policy. The central government has refused to formally acknowledge a need for an immigration policy, viewing immigrants as a threat to public order and cultural homogeneity. Despite this, local governments still need to address the needs of their foreign residents and maintain the peace in the local communities. Some of these policies dovetail with each other; others have no counterpart on the other level of governance. What one can then observe with the national government in Tokyo and the local governments instead is a patchwork that involves some tangential, but for the main part, …

Sex Differences In Active Avoidance And Neural Circuit Mechanisms In Contextual Fear Generalization, Carly Vincent

Theses and Dissertations

The current studies were aimed to investigate two behavioral hallmarks of anxiety and stress-related disorders, avoidance responses and the over-generalization of fear. In the first set of studies, active avoidance and extinction learning, that parallels exposure therapy in preclinical rodent models, were used. It is known that stress can influence aversive learning and extinction training, which can result in poor extinction retention. However, it is not well understood how the stress response is facilitating extinction resistance in active avoidance learning across sexes. Therefore, the first set of studies aimed to investigate the role of biological sex and glucocorticoid receptor (GR) …

Mitochondrial Function In The Maternal Brain: A New Perspective On Gestational Stress And Pathology Of Postpartum Depression, Erin Rene Gorman-Sandler

Theses and Dissertations

Postpartum depression (PPD) is a major psychiatric complication of childbirth, affecting up to 20% of mothers, yet remains understudied. Mitochondria, dynamic organelles crucial for cell homeostasis and energy production, share links with many of the proposed mechanisms underlying PPD pathology. Brain mitochondrial function is affected by stress, a major risk factor for development of PPD, and is linked to avoidance and social behaviors. Considering the importance of mitochondria in regulating brain function and behavior, we hypothesized that mitochondrial dysfunction is associated with behavioral alterations in a chronic stress-induced rat model of PPD. Chronic mild unpredictable (CMUS) stress during late gestation …
