Inhibition of the LH Surge by Restraint Stress in Cyclic Rats: Studies on the Role of GABAA and GABAB Receptors

There is evidence that stress can alter the activity in the brain of gamma-aminobutyricacid (GABA), a neurotransmitter that has been implicated in the regulation of LH secretion. In the present study the role of GABA in the restraint stress-induced inhibition of the LH surge was investigated in the intact cyclic rat. Intracerebroventricular (icv) administration of the GABAA receptor agonist muscimol (0.1, 0.5 or 1 μg) 5 min before the presumed onset of the pro-oestrous LH surge (at 0900 h) caused a dose dependent suppression of the surge. A single dose of the GABAB receptor agonist baclofen (1 μg; icv) injected at 0855 h postponed the onset of the LH surge, and repeated injections at 0855 and 1130 h suppressed the surge. These data indicate that GABA-ergic activity in the brain can inhibit the LH surge in the cyclic rat via GABAA and GABAB receptors. Pro-oestrous rats were subjected to 5 hrs of restraint starting at 0855 h. Pretreatment with the GABAA receptor antagonist bicuculine (1 μg; icv) at 0840, 0940 and 1040 h or pretreatment with the GABAB receptor antagonist phaclofen (10 μg; icv) at 0840 h were ineffective in preventing the restraint-induced inhibition of the LH surge. The results suggest that GABAA and GABAB receptors are not involved in the inhibitory effect of restraint stress on the LH surge.     

Curious Disappearances: Affectability Imbalances and Process‐Based Invisibility

In this paper, we analyze the recent public scandal involving Nafissatou Diallo and Dominique Strauss‐Kahn to offer an account of the role affectability imbalances play in process‐based invisibility. Process‐based invisibilities, in this paper, refer to predictable narrative gaps within public narratives that can be aptly described as disappearances. We demonstrate that compromised, complex social identities, maladjusted webs of reciprocity, and a failure to fully appreciate basic affectability in large part cause affectability imbalances. Ultimately, we claim that affectability imbalances and the three imbricated conditions that facilitate such imbalances—complex social identities, reciprocity, and basic affectability—are integral features of process‐based invisibility.     

Characteristics of the Florida cognitive activities scale in older African Americans

Substantial research effort has recently focused on the potential protective effect of cognitively demanding activities on cognitive decline in late life. A significant methodological issue in this effort has been the lack of consistency in approaches to the operational measurement of cognitive activity. In this study, data in support of the reliability and construct validity of the recently developed Florida Cognitive Activities Scale (FCAS) in a sample of 223 African American older adults are provided. Consistent with the findings of the Schinka et al. study using a sample of Whites, the FCAS full scale showed a reasonably high level of internal consistency, small negative correlations with age and a measure of depressive symptomatology, and moderate positive correlations with years of education and neuropsychological measures of overall cognitive functioning, memory, and executive functioning. Even after controlling for the effects of age, education, and gender, the full scale score contributed significantly to the prediction of global cognitive functioning. The results of this study suggest that the FCAS is a reliable and valid measure of cognitive activities in older African Americans and provides additional, although not causative, evidence in support of the hypothesis of a protective effect of cognitive activity against cognitive decline regardless of ethnicity or race.     

Supervisory styles index: Examining supervisees' perceptions of Supervisory Style

The goal of this research was to develop an instrument, the Supervisory Styles Index (SSI), that would examine supervisory style. Style has been described as the way in which the personality and convictions of the supervisor are demonstrated in the supervisory relationship (Leighton, 1991). This study focuses on the interplay between supervisory style and the influence of sex and gender. The findings of this study reveal that female supervisees discern their supervisors to be more self-disclosing than do male supervisees. Implications of the findings and utilization of the index are discussed.Portions of this paper were presented at the 52nd annual conference of the American Association for Marriage and Family Therapy, Chicago, Illinois, November, 1994.     

Who has to act? A qualitative exploration of emerging adults' critical consciousness during the COVID-19 pandemic

The COVID-19 pandemic and violence against people of Color during 2020 brought troubling racial inequities to the forefront of American discourse. In line with the Critical Consciousness (CC) and Social Justice Youth Development (SJYD) frameworks, emerging adults may have developed their capacity for critical reflection, motivation, and action against systemic inequities. We drew from interviews with 27 emerging adults (ages 18–23) across the US, and used thematic analysis to explore differences in their reflections, motivations to act, and actions based on their racial/ethnic identification. We found nuanced variability in their critical reflections based on self, social, or global awareness and experiences of marginalization. White and Asian emerging adults used vague language or expressed feeling their reflections were insufficient. Black and Latinx emerging adults emphasized the importance of education and raising awareness. Although all emerging adults took action based on a sense of duty, few engaged in critical action; decisions to take in-person action varied based on whether they viewed racism or COVID-19 as a greater threat. Findings demonstrate that emerging adults' experiences of racialization may have related to their CC development. We share implications for community psychologists conducting antiracist research addressing White fragility and dismantling racial hierarchy.     

Tales from an apostate

Here I outline an often under‐appreciated position within Anglo‐analytic epistemology, that of the apostate to operative metaphilosophical constraints. To help identify and promote awareness of metaphilosophical apostacy, here, I describe the form of metaphilosophical apostacy that I practice in Anglo‐analytic epistemology (AAE). My apostasy with respect to AAE begins with significant, metaphilosophical divergences or deep senses of incongruence. A metaphilosophical divergence, on my account, refers to conflict at the level of inquiry‐shaping assumptions, constraints, aims, and/or commitments. In this paper, I claim that one way metaphilosophical apostasy emerges in Anglo‐analytic epistemology is when inquiry‐shaping divergences lead to conceptual indifference. Conceptual indifference, on my account, refers to disinterest that can follow from divergent metaphilosophical and/or aspirational aims and goals for one's favored investigations. To be clear, this is a paper for the growing population of epistemologists who find operative metaphilosophical constraints in AAE ill‐fitting.
