Relationship between maternal aggression and maternal care in the rat

Aggression among female rats is almost entirely confined to the period of late pregnancy and lactation. Behaviorally it is similar to the aggression of males including piloerection and lateral attacks, but it differs in its function. Unlike male aggression which serves to establish a social hierarchy and a territory, i. e., is competitive, maternal aggression is protective, i. e., it serves to prevent predation of the mother's offspring. In this respect it is closely related temporally and causally to maternal care; if the offspring are removed maternal aggression wanes almost immediately–its function no longer exists! Studies on aggression by mothers, among rats, from the author's laboratory are reviewed and comparisons made with maternal care. As noted, maternal aggression and maternal care are closely related during the cycle of maternal behavior and they share a similar hormonal basis and possibly the effect of uterine stimulation, but maternal care requires prolactin and the decline of progesterone while maternal aggression appears independent of pituitary hormones and does not require a decline in progesterone. Maternal aggression like maternal care appears to be organized into a hormonal phase, during pregnancy, parturition, and for about a week postpartum and a nonhormonal phase thereafter. Bilateral radiofrequency lesions of the lateral midbrain peripeduncular nucleus (PPN) produce deficits in maternal aggression if made on lactation day 7 (L7), but not earlier, without producing significant deficits in maternal behavior. Experiments showed that the PPN does not mediate hormonally stimulated maternal aggression; it appears to mediate only nonhormonally stimulated maternal aggression. Studies on the role of pregnancy hormones on long-term retention of maternal aggression and the role of olfaction in maternal aggression are also reviewed. © 1994 Wiley-Liss, Inc.     

Feeling activated and acting unethically: The influence of activated mood on unethical behavior to benefit a teammate

Research on the effects of mood in organizations tends to focus on the valence dimension of mood (positive vs. negative), overlooking the activation dimension (activated vs. deactivated). We suggest that activation level prompts unethical behavior. Based on the affective infusion model (AIM; Forgas, 1995), we predict that positive activated and negative activated moods facilitate unethical behavior to benefit a teammate, via the mediating mechanism of a creative mindset. We test our full model using an experience sampling method over 2 weeks, in which mood and creative mindset were assessed in the morning and unethical behavior conducted that day was assessed in the evening. We found that activated moods (both positive and negative) were positively related to unethical behavior to benefit a teammate. Further, creative mindset mediated the relationship between positive activated mood and unethical behavior to benefit a teammate. Consistent with AIM's claim that mood should influence decisions more when they are not personally relevant, we found that moral disengagement propensity moderated this indirect effect. In addition, we conducted two experiments to examine further the mood-creative mindset and creative mindset-unethical behavior to benefit a teammate relationship. Our findings affirm that activated versus deactivated moods facilitate a creative mindset, and that a creative mindset encourages unethical behavior to benefit a teammate. Our findings suggest that activation level of mood plays a critical role in unethical behavior.     

Latinx Mental Health Scholars' Experiences with Cultural Adaptation and Implementation of Systemic Family Interventions

An increasing number of culturally adapted family-level interventions address mental health disparities with marginalized populations in the United States. However, with these developments many barriers have arisen, such as challenges with degree of cultural fit, engagement, and sustainability. We conducted 12 elite phenomenological interviews with mental health scholars involved in prevention and intervention family research with various Latinx communities within and outside of the United States. These scholars discussed their experiences of overcoming barriers in their research. We used thematic analysis to code and analyze participant responses, and our findings support the gaps in previous literature and highlight potential pathways to overcoming barriers in cultural adaptation research. Themes included the need for: (a) better understanding of the intersection between culture and context; (b) community-centered approaches to addressing implementation challenges; and (c) structural changes within institutional, governmental, and political levels. We discuss implications for researchers and practitioners working with Latinx families.     

Healthcare Chaplains’ Perspectives on Nurse–Chaplain Collaboration: An Online Survey

The collaboration between nurses and chaplains is essential to provide spiritual support in healthcare institutions. Given challenges in collaboration exist between these disciplines, this study sought to further understand the nature of the chaplain–nurse relationship. Data obtained from an online survey of members of the Association of Professional Chaplains (N = 266) provide a quantified and nuanced picture of how chaplains perceive nurse collaboration and provision of spiritual care. This study not only provides evidence that can inform chaplain and nurse practice, but also an instrument for measuring perceptions about collaboration to provide spiritual care.

     

Concealability beliefs facilitate navigating intergroup contexts

Living in a diverse world requires the ability to navigate intergroup contexts. However, interacting with outgroup members can cause anxiety that leads to lower-quality interactions and avoidance of future contact. One reason people experience this anxiety is the concern that others will judge them on the basis of an identity. These concerns may be reduced among people who believe the identity is unperceivable by others. The belief that one's identity is concealable may therefore reduce intergroup anxiety and ease people's experiences in intergroup contexts. The present work tests this proposition in two studies and finds that individual differences in concealability beliefs are negatively associated with intergroup anxiety and positively associated with the propensity to initiate intergroup contact and with the quantity and quality of people's cross-group friendships. Materials, data, and code for both studies and a pre-registration for Study 2 are available online ( https://osf.io/4cjhg/ ).     

Partner–objectification in romantic relationships: A dyadic approach

The present study investigated the relationship between the objectification of one's romantic partner (partner–objectification) and relationship quality using 221 heterosexual couples. Controlling for relevant covariates, actor–partner interdependence models revealed no partner effects but multiple actor effects. First, men who objectified their partners more had lower levels of relationship commitment and relationship satisfaction, and perceived higher quality alternatives to the relationship. Second, women who objectified their partners more had lower levels of relationship satisfaction themselves. Third, relationship duration marginally moderated the association between partner–objectification and relationship commitment, with partner–objectification negatively linked to one's own relationship commitment in relationships of shorter durations, but not when relationship durations were longer. Implications for an investment model and romantic relationship objectification are discussed.     

Loneliness,eating, and body mass index in parent–adolescent dyads from the Family Life,Activity, Sun,Health, and Eating study

Loneliness is a salient risk factor for obesity, emotional eating, and poor diet. Because adolescents and parents are embedded within a family unit, their experiences of loneliness may be associated with both their own and one another's behaviors. To examine the extent to which parent and child loneliness predict body mass index (BMI) and eating in parents and adolescents, an actor–partner interdependence model of loneliness, eating, and BMI in adolescent–parent dyads was analyzed. There were actor effects among adolescents such that greater loneliness was positively associated with emotional eating and BMI‐z, and there was an actor effect among parents such that higher loneliness was positively related to emotional eating. There was a partner effect among adolescents such that greater parental loneliness was positively associated with adolescent emotional eating, and there was a partner effect among parents such that higher adolescent loneliness was positively associated with parental emotional eating. There were several actor–partner effects for loneliness and junk food in dyads with boys. Findings highlight the importance of dyadic models of loneliness in adolescent–parent dyads.     

Facebook rituals: Identifying rituals of social networking sites using structural ritualization theory

This article applies structural ritualization theory (SRT) to identify different rituals and determine their importance in the daily lives of social networking sites (SNS) users, especially Facebook users. A mixed‐methods approach of in‐depth interviews and netnography viewed through the lens of SRT allowed us to identify and analyze the types of rituals users engaged in, and how these rituals impacted users and evolved over time. During customer journeys on the SNS of Facebook, users shared daily ritual practices in distinct behavioral stages. Production and consumption of these daily rituals are important to marketers in SNS platform design for building and maintaining connectivity between users and the SNS platform.     

Do Prosecutors Use Interview Instructions or Build Rapport with Child Witnesses?

This study examined the quality of interview instructions and rapport-building provided by prosecutors to 168 children aged 5–12 years testifying in child sexual abuse cases, preceding explicit questions about abuse allegations. Prosecutors failed to effectively administer key interview instructions, build rapport, or rely on open-ended narrative producing prompts during this early stage of questioning. Moreover, prosecutors often directed children's attention to the defendant early in the testimony. The productivity of different types of wh- questions varied, with what/how questions focusing on actions being particularly productive. The lack of instructions, poor quality rapport-building, and closed-ended questioning suggest that children may not be adequately prepared during trial to provide lengthy and reliable reports to their full ability.
