Aggressive behavior is instinctively driven behavior that helps animals to survive and reproduce and is closely related to multiple behavioral and physiological processes. The dorsal raphe nucleus (DRN) is an evolutionarily conserved midbrain structure that regulates aggressive behavior by integrating diverse brain inputs. The DRN consists predominantly of serotonergic (5‐HT:5‐hydroxytryptamine) neurons and decreased 5‐HT activity was classically thought to increase aggression. However, recent studies challenge this 5‐HT deficiency model, revealing a more complex role for the DRN 5‐HT system in aggression. (...) Furthermore, emerging evidence has shown that non‐5‐HT populations in the DRN and specific neural circuits contribute to the escalation of aggressive behavior. This review argues that the DRN serves as a multifaceted modulator of aggression, acting not only via 5‐HT but also via other neurotransmitters and neural pathways, as well as different subsets of 5‐HT neurons. In addition, we discuss the contribution of DRN neurons in the behavioral and physiological aspects implicated in aggressive behavior, such as arousal, reward, and impulsivity, to further our understanding of DRN‐mediated aggression modulation.

Families of children with mental health challenges may have been particularly vulnerable to emotional distress during the COVID-19 pandemic. This cross-sectional study surveyed 81 parents of children ages 6–17 years receiving mental health treatment in an outpatient clinic during the pandemic. We sought to characterize the impact of the pandemic on family relationships and parental well-being. Additionally, regression and ANCOVA models examined associations between four potentially protective factors—parents’ psychological resilience, perceived social support, positive family experiences during the pandemic, and children’s (...) use of cognitive or behavioral coping strategies—with family relationships and parental well-being. Findings suggest that families of children with mental health conditions experienced remarkable challenges to family relationships, parental well-being, and parents’ perceived capacity to support their children’s mental health. Nearly 80% of parents reported a negative impact of the pandemic on their own well-being, and 60% reported reduced ability to support their children’s mental health. Simultaneously, protective factors appeared to mitigate the negative impact of the pandemic. Particularly, support within the family and from external sources were associated with better self-reported well-being for parents and their capacity to support their children. Children’s use of coping tools, likely enhanced by mental health treatment, was also positively related to better family relationships and parental ability to support children with mental health challenges. Our findings highlight the need for enhancing supports for families at multiple levels including individual skill-building, family-based/parenting support, and community-based support. (shrink)

Technical reasoning refers to making inferences about how to use tools. The degree of technical reasoning is indicated by the bias of the gaze on the functional part of the tool when in use. Few studies have examined whether technical reasoning differs between familiar and unfamiliar novel tools. In addition, what effect the intention to use the tool has on technical reasoning has not been determined. This study examined gaze shifts in relation to familiar or unfamiliar tools, under three conditions, (...) among 14 healthy adults. The cumulative fixation time on the functional part of the tool served as a quantitative indicator of the degree of technical reasoning. The two-way analysis of variance for tools and conditions revealed that the cumulative fixation time significantly increased under free viewing and use conditions, compared to lift conditions. Relative to the free viewing condition, cumulative fixation time for unfamiliar tools significantly decreased in the lift condition and significantly increased in the use condition. Importantly, the results showed that technical reasoning was performed in both the use and the free viewing conditions. However, technical reasoning in the free viewing condition was not as strong as in the use condition. The difference between technical reasoning in free viewing and use conditions may indicate the difference between automatic and intentional technical reasoning. (shrink)

Urban agriculture is a promising avenue for food system change; however, projects often struggle with a lack of volunteers—limiting both their immediate goals and the broader movement-building to which many alternative food initiatives (AFIs) aspire. In this paper, I adopt a case study approach focusing on Farm X, an urban farm with a strong volunteer culture located in Tāmaki-Makaurau Auckland, New Zealand’s largest city. Drawing on a significant period of researcher participation and 11 in-depth interviews with volunteers and project coordinators, (...) I first contextualise and explore the history of Farm X, then offer themes to describe key factors which help or hinder their volunteer engagement. Engagement is helped by strong leadership, learning by doing, socialising around plants, and contributing to a movement. Conversely, engagement is hindered by time scarcity, economic hurdles, and struggles over direction. Drawing on McClintock’s (Local Environ 19(2): 147–171, 2014, 10.1080/13549839.2012.752797) insights into the hybrid and contradictory nature of urban agriculture as a tool for social change, the paper continues with a discussion of two important trade-offs involved in both farm management and the movement building promoted by Farm X: focused leadership verses volunteer agency; and asking more verses less of volunteers. Finally, I suggest several avenues that may be useful for other urban agriculture projects interested in movement building. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:preface This special issue of Feminist Studies presents an eclectic view of women ’s friendships from across Western history and from several different cultures. Several of the articles question whether identity or sameness is a prerequisite for friendship and ask what friendships across difference look like, including charting the difficulties of making and sustaining such friendships. The articles in this issue contrast the variety and functions of women’s friendships (...) with the narcissistic masculinist ideals of classical Western thought about friendship in which friends serve as reflections of a person—typically a male and upper-class person. The authors in this issue present women’s friendships that are more pragmatic and more vulnerable and that contend more fully with difference. Some authors reflect on the high expectations placed on friendship within Second Wave feminism in the United States, noting how competition and feelings of betrayal can suffuse friendships; others trace more autonomous, productive, and forgiving contemporary visions of friendship. The issue opens with Susan Van Dyne’s archival study of student friendships in a pioneering US women’s college, revealing how love, flirtation, and desire between women was expressed in Smith College’s class of 1883. In another historical study, sociologist Harriet Bjerrum Nielsen contrasts the narratives of Norwegian girls and young women from the late nineteenth century with those of present-day women and girls, noting differences between rural and urban contexts. Ivy Schweitzer 272Preface surveys classical Western masculinist ideals of friendship from Aristotle to Montaigne and traces the transformation of this tradition into the present quest for equality without hierarchy. Alexandra Verini addresses models of female friendship in the European Middle Ages, arguing that Christine de Pizan and Margery Kempe illustrate a “viable female alternative ” to classical models. The vulnerability of women’s close relationships comes to the fore in Nancy K. Miller’s moving elegies for deceased feminist friends, while Judith Taylor explores the more open and autonomous friendships adumbrated in contemporary fictions by Zadie Smith and Jillian and Mariko Tamaki, themes also addressed in Judith Kegan Gardiner’s review essay of advice books on friendships between women and other studies of women’s friendships. Richa Nagar’s interview articulates an ideal of feminist friendships that “enable continuous evolution of our beings and mindsets... without feeling threatened by one another.” If our articles focus on the close bonds between women, our News and Views pieces in this issue point to collective ties formed in response to political and social threats: Dalia Abd El-Hameed and Nadine Naber describe responses by Egyptian feminists to government crackdowns, and our forum “Orlando: Observances” offers a selection of first-person accounts from vigils organized to mark the massacre at the Pulse nightclub this summer. This issue also presents internal negotiations of identity, identification, and body image in Stephanie Han’s short story and in the vivid and bold transgressions of Wangechi Mutu’s collages as described by Sarah Jane Cervenak. In “‘Abracadabra’: Intimate Inventions by Early College Women,” Susan Van Dyne takes us on a fascinating journey into the “the early formation of a homosocial student culture and the bonds between women” at Smith College in the late nineteenth century. Mining an archive of diaries, letters, photos, and other materials from a group of friends from the class of 1883, she focuses on two kinds of written evidence: one, the inchoate expressions of homoerotic desire in one student’s journal at a moment when “lesbian” did not yet exist as an identity, and the other, a love poem to two students, written as a parody by one of their women professors, but which reverberated beyond the college and ignited male opprobrium. In her discussions of these developments, rather than ascribing identity, Van Dyne navigates the “messiness” of the archive, keeping her eye trained on the “only partially intelligible strategies of self-representation that can’t be translated or reduced to the modern Preface 273 language of sexual self-recognition.” What is most surprising in her account is not that young women would feel desire for one another, nor that male peers or authorities might find this threatening, but that the fabric of the students’ homosocial community had such resilience, nurturing...
