Dominance in humans

Dominance captures behavioural patterns found in social hierarchies that arise from agonistic interactions in which some individuals coercively exploit their control over costs and benefits to extract deference from others, often through aggression, threats and/or intimidation. Accumulating evidence points to its importance in humans and its separation from prestige—an alternate avenue to high status in which status arises from information (e.g. knowledge, skill, etc.) or other non-rival goods. In this review, we provide an overview of the theoretical underpinnings of dominance as a concept within evolutionary biology, discuss the challenges of applying it to humans and consider alternative theoretical accounts which assert that dominance is relevant to understanding status in humans. We then review empirical evidence for its continued importance in human groups, including the effects of dominance—independently of prestige—on measurable outcomes such as social influence and reproductive fitness, evidence for specialized dominance psychology, and evidence for gender-specific effects. Finally, because human-specific factors such as norms and coalitions may place bounds on purely coercive status-attainment strategies, we end by considering key situations and contexts that increase the likelihood for dominance status to coexist alongside prestige status within the same individual, including how: (i) institutional power and authority tend to elicit dominance; (ii) dominance-enhancing traits can at times generate benefits for others (prestige); and (iii) certain dominance cues and ethology may lead to mis-attributions of prestige.

Behavioural and physiological plasticity in social hierarchies

Individuals occupying dominant and subordinate positions in social hierarchies exhibit divergent behaviours, physiology and neural functioning. Dominant animals express higher levels of dominance behaviours such as aggression, territorial defence and mate-guarding. Dominants also signal their status via auditory, visual or chemical cues. Moreover, dominant animals typically increase reproductive behaviours and show enhanced spatial and social cognition as well as elevated arousal. These biobehavioural changes increase energetic demands that are met via shifting both energy intake and metabolism and are supported by coordinated changes in physiological systems including the hypothalamic–pituitary–adrenal and hypothalamic–pituitary–gonadal axes as well as altered gene expression and sensitivity of neural circuits that regulate these behaviours. Conversely, subordinate animals inhibit dominance and often reproductive behaviours and exhibit physiological changes adapted to socially stressful contexts. Phenotypic changes in both dominant and subordinate individuals may be beneficial in the short-term but lead to long-term challenges to health. Further, rapid changes in social ranks occur as dominant animals socially ascend or descend and are associated with dynamic modulations in the brain and periphery. In this paper, we provide a broad overview of how behavioural and phenotypic changes associated with social dominance and subordination are expressed in neural and physiological plasticity.

Social hierarchies and social networks in humans

Across species, social hierarchies are often governed by dominance relations. In humans, where there are multiple culturally valued axes of distinction, social hierarchies can take a variety of forms and need not rest on dominance relations. Consequently, humans navigate multiple domains of status, i.e. relative standing. Importantly, while these hierarchies may be constructed from dyadic interactions, they are often more fundamentally guided by subjective peer evaluations and group perceptions. Researchers have typically focused on the distinct elements that shape individuals’ relative standing, with some emphasizing individual-level attributes and others outlining emergent macro-level structural outcomes. Here, we synthesize work across the social sciences to suggest that the dynamic interplay between individual-level and meso-level properties of the social networks in which individuals are embedded are crucial for understanding the diverse processes of status differentiation across groups. More specifically, we observe that humans not only navigate multiple social hierarchies at any given time but also simultaneously operate within multiple, overlapping social networks. There are important dynamic feedbacks between social hierarchies and the characteristics of social networks, as the types of social relationships, their structural properties, and the relative position of individuals within them both influence and are influenced by status differentiation.

Mobile, Alabama’s Joe Cain Procession

This article investigates the contradictions that characterize Mobile, Alabama’s Joe Cain Day celebration. We look at the official narratives that established Mobile’s Mardi Gras origin myths and the event’s tradition invention in 1967 with a People’s Parade centered around Cain’s redface character, Chief Slacabamorinico. Then we discuss the complicated and ever-evolving symbolism surrounding the character by discussing more recent iterations of this public performance. In its inception, the Joe Cain celebration was a clear example of Lost Cause nostalgia, yet it has been adopted, adapted, and embraced by historically marginalized people who use it as a way to claim their space in the festivities. Employing both historical and ethnographic research, we show that carnival can simultaneously be a space for defiance and reaffirmation of social hierarchies and exclusionary discourses. We discuss here some of the concrete material elements that lend this public performance its white supremacist subtext, but we also want to complicate the definition of “materiality” by claiming a procession as a Confederate monument/memorial.

Transcultural capital and emergent identities among migrant youth

The everyday practices and socio-cultural identities of migrant youth have become a focal point of contemporary sociological research in Western countries of immigration. This article engages with the concept of transcultural capital to frame the possibilities and opportunities embodied in young migrants’ multi-layered identities and cross-cultural competencies in the context of an increasingly interconnected and diverse world. By re-conceptualising diversity and difference as agentic, transformational capitals to be valued, fostered and mobilised, this transcultural approach brings to the fore the multitude of skills, networks and knowledge that migrant youth access and develop through multiple cultural repertoires. Drawing on the narratives of migrant youth in Melbourne (Australia), this article argues that access to different – and not necessarily oppositional – cultural systems opens up a space for understanding the ability of migrant youth to instigate, negotiate and maintain valuable socio-cultural connections in ways that recognise, disrupt and transform social hierarchies.

“We’re All Equal” But Not Really: Perceptions of Racial Inequity Among Racial-Ethnic Minoritized Youth in the U.S

Racial-ethnic inequity is deeply entrenched in U.S. social systems, yet adolescents’ voices and understanding around inequity are not often directly examined. The current qualitative study uses focus group data from African American ( n = 21), Chinese- ( n = 17), Indian- ( n = 13), and Mexican- ( n = 17) origin adolescents ( Mage = 12.93 years; SD = 1.23; 51% boys) to provide insight on how youth navigate their attitudes and beliefs about these issues. Using a racial-ethnic socialization lens, we explore proximal (e.g., parents, peers, teachers) and distal (e.g., media, society) ways in which adolescents come to understand racial-ethnic inequity. Three themes characterized adolescents’ discussions. School diversity, of peers and of thought, and messages around egalitarianism were two prominent influences on their perceptions. A third theme related to perceptions of social hierarchies, which appeared to be shaped by stereotypes, peer interactions, and ideas about inequity itself. Emergent themes suggest that the school context is a particularly salient social setting that encompasses multiple sources of socialization (e.g., teachers, classmates, academics, climate), and parents, peers, and the media also play prominent roles.

CRISPR/Cas9-mediated generation of biallelic F0 anemonefish (Amphiprion ocellaris) mutants

Genomic manipulation is a useful approach for elucidating the molecular pathways underlying aspects of development, physiology, and behaviour. However, a lack of gene-editing tools appropriated for use in reef fishes has meant the genetic underpinnings for many of their unique traits remain to be investigated. One iconic group of reef fishes ideal for applying this technique are anemonefishes (Amphiprioninae) as they are widely studied for their symbiosis with anemones, sequential hermaphroditism, complex social hierarchies, skin pattern development, and vision, and are raised relatively easily in aquaria. In this study, we developed a gene-editing protocol for applying the CRISPR/Cas9 system in the false clown anemonefish, Amphiprion ocellaris. Microinjection of zygotes was used to demonstrate the successful use of our CRISPR/Cas9 approach at two separate target sites: the rhodopsin-like 2B opsin encoding gene (RH2B) involved in vision, and Tyrosinase-producing gene (tyr) involved in the production of melanin. Analysis of the sequenced target gene regions in A. ocellaris embryos showed that uptake was as high as 73.3% of injected embryos. Further analysis of the subcloned mutant gene sequences combined with amplicon shotgun sequencing revealed that our approach had a 75% to 100% efficiency in producing biallelic mutations in F0 A. ocellaris embryos. Moreover, we clearly show a loss-of-function in tyr mutant embryos which exhibited typical hypomelanistic phenotypes. This protocol is intended as a useful starting point to further explore the potential application of CRISPR/Cas9 in A. ocellaris, as a platform for studying gene function in anemonefishes and other reef fishes.

Decadent Ecology in British Literature and Art, 1860–1910

Casting fresh light on late nineteenth- and early twentieth-century British art, literature, ecological science and paganism, Decadent Ecology reveals the pervasive influence of decadence and paganism on modern understandings of nature and the environment, queer and feminist politics, national identities, and changing social hierarchies. Combining scholarship in the environmental humanities with aesthetic and literary theory, this interdisciplinary study digs into works by Simeon Solomon, Algernon Swinburne, Walter Pater, Robert Louis Stevenson, Vernon Lee, Michael Field, Arthur Machen and others to address trans-temporal, trans-species intimacy; the vagabondage of place; the erotics of decomposition; occult ecology; decadent feminism; and neo-paganism. Decadent Ecology reveals the mutually influential relationship of art and science during the formulation of modern ecological, environmental, evolutionary and trans-national discourses, while also highlighting the dissident dynamism of new and recuperative pagan spiritualities - primarily Celtic, Nordic-Germanic, Greco-Roman and Egyptian - in the framing of personal, social and national identities.
