The paper derives sufficient conditions for the consistency and asymptotic normality of the least squares estimator of a trilinear decomposition model for multiway data analysis.     

Centering culture in the treatment of opioid use disorder with American Indian and Alaska Native Communities: Contributions from a National Collaborative Board

American Indian/Alaska Native (AI/AN) communities are disproportionally impacted by the opioid overdose epidemic. There remains a dearth of research evaluating methods for effectively implementing treatments for opioid use disorder (OUD) within these communities. We describe proceedings from a 2-day Collaborative Board (CB) meeting tasked with developing an implementation intervention for AI/AN clinical programs to improve the delivery of medications to treat OUD (MOUD). The CB was comprised of Elders, cultural leaders, providers, individuals with lived experience with OUD, and researchers from over 25 communities, organizations, and academic institutions. Conversations were audio-recorded, transcribed, and coded by two academic researchers with interpretation oversight provided by the CB. These proceedings provided a foundation for ongoing CB work and a frame for developing the program-level implementation intervention using a strength-based and holistic model of OUD recovery and wellbeing. Topics of discussion posed to the CB included engagement and recovery strategies, integration of extended family traditions, and addressing stigma and building trust with providers and clients. Integration of traditional healing practices, ceremonies, and other cultural practices was recommended. The importance of centering AI/AN culture and involving family were highlighted as priorities for the intervention.     

Adjusting Social Inferences in Familiar and Unfamiliar Domains: The Generality of Response to Situational Pragmatics

Two experiments investigated the influence of situational pragmatics on the selective use of specific instances and generalized knowledge structures to make social inferences. In Experiment 1, social inferences were made in an unfamiliar domain similar in structure to a typical situation of social greetings and address, but devoid of useful cues to social schemas. Participants were told that either one or another of the features of the situation was more pragmatically important for deriving inferences about appropriate social behaviour; consistent with predictions from a computational model of analogical mapping (ACME), they made reliable inferences based on analogies to specific instances, with the situational importance of relations guiding the selection of the optimal analogue. In Experiment 2, social inferences were examined in the more familiar domain of predicting social behavior between low and high status persons and between members of an ingroup and an outgroup in Japan. The availability of specific examples was varied, as was the perceived importance of status and group membership. The situation was isomorphic to that in the first experiment, except for the availability of generalized knowledge structures to guide inferences. Participants made relatively veridical inferences that were sensitive to variations in the pragmatic importance of dimensions. Provision of specific analogues had little impact on inferences, suggesting that participants were relying instead on more general and cross-culturally applicable knowledge about adjusting social relations according to situational pragmatics.

The relationship between acculturation and problem behavior proneness in a Hispanic youth sample: a longitudinal mediation model

This study, using secondary data analysis, examined prospectively a mediation model of the relationship between acculturation and problem behavior proneness among 330 Hispanic children and adolescents from an urban school district in the southwest region of the United States. Acculturation was predicted to have an indirect, but positive, relationship to problem behavior proneness through parental involvement and self-esteem. The results partially supported the model and indicated that parental involvement, but not self-esteem, played a significant mediational role in children's problem behavior proneness. The individual indicators of problem behavior proneness among Hispanic youth were significantly interrelated, which is consistent with problem behavior theory as conceptualized by R. Jessor (1984) and R. Jessor and S. L. Jessor (1977). Findings from this study provide implications for future research and intervention designs.     

Impaired memory consolidation in rats produced with beta-adrenergic blockade

Despite abundant evidence that systemic administration of adrenergic drugs and hormones can produce retrograde memory enhancement, the literature contains no clear demonstration that postlearning systemic administration of adrenergic antagonists produces retrograde amnesia. Here we demonstrate retrograde amnesia for a stressful learning task (a spatial water maze) with systemic administration of the beta-adrenergic antagonist propranolol (5 mg/kg). The amnesic effect of the drug depended on the degree of learning in the subjects: Propranolol caused a robust retrograde amnesia in "good learners," but did not significantly affect memory in "poor learners." The findings provide critical additional support for the hypothesis that postlearning adrenergic activation modulates memory consolidation processes after emotionally stressful events and help explain previous failures to detect memory impairment after systemic administration of adrenergic blocking drugs.     

Beyond the Obvious: Chronic Vividness of Imagery and the Use of Information in Decision Making

The authors investigate two competing hypotheses about how chronic vividness of imagery interacts with the vividness and salience of information in decision making. Results from four studies, covering a variety of decision domains, indicate that chronic imagery vividness rarely amplifies the effects of vivid and salient information. Imagery vividness may, in fact, attenuate the effects of vivid and salient information. This is because, relative to nonvivid imagers, vivid imagers rely less on information that appears obvious and rely more on information that seems less obvious. This tendency is so robust that vividness of imagery may amplify the effects of vivid information only when this information is the only information available in the decision field. The findings seem to reflect vivid imagers' tendency to totally immerse themselves in a decision problem and scrutinize the available information creatively.     

The Sex-Based Harassment Inventory: A Gender Status Threat Measure of Sex-Based Harassment Intentions

Sex Roles - We introduce a new inventory measuring sex-based harassment intentions and threat perceptions grounded in gender status threat theories (Berdahl, 2007; Stephan et al., 2016). In Study 1...     

Cultural Adaptation and Sexual Harassment in the Lives of Asian American Women

ABSTRACT

Despite the prevalence of both historical and current race- and gender-based stereotyping of Asian American women, little is known about their experiences and attitudes regarding sexual harassment. In this study, 109 Asian American women enrolled in a state university or a 2-year community college responded to questionnaires about cultural orientation, experiences of sexual harassment, and sexual harassment attitudes. Asian cultural orientation was associated with sexual harassment attitudes. Specifically, among women with low White cultural orientation, there was a statistically significant positive association between Asian cultural orientation and acceptance of sexual harassment. Results from this study have important implications for clinical practice with Asian American women, including issues of migration, cultural orientation, and the intersection of racism and sexism in the United States.
