Social ageing and higher-order interactions: social selectiveness can enhance older individuals' capacity to transmit knowledge.

In long-lived organisms, experience can accumulate with age, such that older individuals may act as repositories of ecological and social knowledge. Such knowledge is often beneficial and can spread via social transmission, leading to the expectation that ageing individuals will remain socially well-integrated. However, social ageing involves multiple processes that modulate the relationship between age and social connectivity in complex ways. We developed a generative model to explore how social ageing may drive changes in social network position and shape older individuals' capacity to transmit knowledge to others. We further employ novel hypernetwork analyses that capture higher-order interactions (i.e. involving ≥ 3 participants) to reveal potential relationships between age and sociality that conventional dyadic networks may overlook. We find that older individuals in our simulations effectively facilitate transmission across a range of scenarios, especially when transmission resembles a complex contagion or when social selectivity (i.e. prioritization of key relationships) rapidly emerges with age. These patterns result from the formation of tight-knit sets of older associates that co-occur in multiple groups, thereby reinforcing one another's capacity to transmit knowledge. Our findings suggest key avenues for future empirical work and illustrate the use of hypernetworks in advancing the study of social behaviour.This article is part of the discussion meeting issue 'Understanding age and society using natural populations'.

A scoping review on barriers and facilitators to harm reduction care among youth in British Columbia, Canada

BackgroundProgressive harm reduction policies have been implemented in British Columbia, Canada. However, youth who use drugs face barriers to receiving harm reduction care, resulting in increasing opioid-related hospitalizations and drug toxicity deaths. This scoping review collates peer-reviewed evidence to understand the barriers and facilitators faced by youth who use drugs when accessing harm reduction programming in British Columbia, Canada.MethodsThis scoping review entailed conducting a systematic search of relevant databases to identify relevant articles. Articles were included if they: (i) contained youth falling between the ages of 12 and 26 years old; (ii) explored accessibility, barriers, and/or facilitators to harm reduction care or related topics; (iii) were empirical research articles using primary data (i.e., reviews, grey literature, theoretical or conceptual papers, books, etc. were excluded); and (iv) were available in the English language, given the geographic focus on British Columbia.ResultsA total of 398 sources were identified and ultimately, data from 13 sources were charted and extracted. When investigating barriers to harm reduction care among youth, four themes emerged: self-stigma, service navigation, service delivery, and negative provider interactions. Furthermore, in exploring factors that facilitate harm reduction care for youth, four themes surfaced: ability to meet basic needs, positive provider interactions, social networks, and risk mitigation guidance.ConclusionsThe expansion of harm reduction services in 2016 did not fully address accessibility challenges faced by youth who use drugs. Barriers continue to hinder harm reduction engagement, while supportive networks, positive provider interactions, and the ability to meet basic needs facilitated sustained access. Tailored policy interventions rooted in equity are crucial to improving access to harm reduction services for youth who use drugs.

Building a healthy generation together: parents’ experiences and perceived meanings of a family-based program delivered in ethnically diverse neighborhoods in Sweden

Introduction and aimEthnically diverse neighborhoods encounter pronounced inequalities, including housing segregation and limited access to safe outdoor spaces. Residents of these neighborhoods face challenges related to physical inactivity, including sedentary lifestyles and obesity in adults and children. One approach to tackling health inequalities is through family-based programs tailored specifically to these neighborhoods. This study aimed to investigate parents’ experiences and perceptions of the family-based Open Activities, a cost-free and drop-in program offered in ethnically diverse and low socioeconomic neighborhoods in Sweden.MethodsResearchers’ engagement in 15 sessions of the Open Activities family-based program during the spring of 2022, and individual interviews with 12 participants were held. Data were analyzed using reflexive thematic analysis.ResultsThe analysis resulted in three main themes and seven sub-themes representing different aspects of the program’s meaning to the participants as parents, their families, and communities. The main themes describe how parents feel valued by the program, which actively welcomes and accommodates families, regardless of cultural differences within these neighborhoods. The themes also show how cultural norms perceived as barriers to participation in physical activity can be overcome, especially by mothers who express a desire to break these norms and support girls’ physical activity. Additionally, the themes highlight the importance of parents fostering safety in the area and creating a positive social network for their children to help them resist criminal gang-related influences.ConclusionsThe program’s activities allowed parents to connect with their children and other families in their community, and (re)discover physical activity by promoting a sense of community and safety. Implications for practice include developing culturally sensitive activities that are accessible to and take place in public spaces for ethnically diverse groups, including health coordinators that can facilitate communication between groups. To enhance the impact of this program, it is recommended that the public sector support the creation of cost-free and drop-in activities for families who are difficult to reach in order to increase their participation in physical activity, outreach, and safety initiatives.

How position in the network determines the fate of lexical innovations on Twitter

This study analyzes the diffusion of lexical innovations on Twitter to understand how the social network position of adopters impacts their success. Looking at both successful and failed neologisms, we categorize them into "changes" which become established and "buzzes" which decline over time. Using a corpus of 650 million French tweets, we reconstruct user networks and characterize adopters of innovations during different diffusion phases based on prestige, centrality, clustering, and external ties. In the early innovation phase, change and buzz adopters have similar peripheral profiles. During propagation, changes spread to prestigious, central individuals while buzzes do not, which predicts their eventual success or failure. By the establishment phase, changes reach highly central users with closer external ties. The results align with sociolinguistic theories about weak ties for innovation and strong ties for establishment. Additionally, logistic regression models based on early adopter profiles can predict the fate of innovations. This work sheds light on the diffusion dynamics of online lexical innovations and the crucial role of user network factors.

Social support networks of incarcerated women with opioid use disorder: Differences associated with jail-based substance use treatment

IntroductionSocial support is a critical factor for women's engagement with substance use treatment and recovery, particularly for women with criminal-legal system involvement. However, less is known about the social support networks of incarcerated women, particularly as a function of service engagement. Thus, this paper aims to describe the structure, composition, and function of social support networks of women with opioid use disorder (OUD) incarcerated in jails; and compare network differences between women receiving jail-based substance use treatment and non-treatment participants. MethodsAs part of a larger clinical trial under the NIDA-funded Justice Community Opioid Innovation Network (JCOIN), staff conducted an egocentric social network inventory with women who were randomly selected from eight jails in Kentucky, screened for OUD, and consented (N = 445). Women were asked to name people (alters) who provided them with support in the past 90 days and respond to questions about alters who were named. Bivariate comparisons examined differences in social networks among women who were currently receiving jail-based treatment (29.9 %, n = 133) and those who were incarcerated, but not receiving treatment (70.1 %, n = 312). ResultsOn average, women's social support networks consisted of 2.4 alters (range 1–9). Compared to women with OUD who were not receiving treatment, those in treatment were significantly more likely to name at least one alter who was in recovery (57.9 % vs. 43.9 %, p = .007) and less likely to name a partner (21.8 % vs. 37.8 %, p = .001) or someone who had recently used opioids (9.8 % vs. 24.7 %, p < .001). On average, women in treatment also felt significantly closer to their alters (4.70 vs. 4.55 out of 5, p = .021) and rated alters as fulfilling more types of social support functions (5.54 vs. 5.18 out of 6, p < .001) and recovery support functions (2.83 vs. 2.70 out of 3, p = .016). ConclusionResults suggest that women participating in jail-based substance use treatment reported more positive social support network attributes, including network function and composition. Future research should assess longitudinal changes in networks and associated differences in recovery outcomes as women are released to the community.

Motivations to Enhance One’s Facial Hair: Affiliation, Rivalry, and Stress

Facial hair is a sexually dimorphic trait with potential evolutionary and sociocultural functions. Bearded men are perceived as dominant, aggressive, and masculine, but also as having better parenting skills. Men may intentionally manage the amount and shape of their facial hair as a part of their self-promotion strategy; however, facial hair management entails costs in terms of time, effort, and money. We explored psychological factors associated with facial hair enhancement motivation among men. A total of 414 men (aged 18–40 years) reported the current amount of their facial hair along with their facial hair enhancement motivations, gender role stress, intrasexual competitiveness, and fundamental social motives. Willingness to care for facial hair was associated with the amount of facial hair men claimed to have and correlated with the fundamental social motives of affiliation and social status, intrasexual competition, and gender role stress. Therefore, facial hair enhancement may be regarded as a self-presentation strategy aimed at acquiring a beneficial position in social networks.

Aggressive interactions influence cognitive performance in Western Australian magpies.

Extensive research has investigated the relationship between the social environment and cognition, suggesting that social complexity may drive cognitive evolution and development. However, evidence for this relationship remains equivocal. Group size is often used as a measure of social complexity, but this may not capture intraspecific variation in social interactions. Social network analysis can provide insight into the cognitively demanding challenges associated with group living at the individual level. Here, we use social networks to investigate whether the cognitive performance of wild Western Australian magpies (Gymnorhina tibicen dorsalis) is related to group size and individual social connectedness. We quantified social connectedness using four interaction types: proximity, affiliative, agonistic and vocal. Consistent with previous research on this species, individuals in larger groups performed better on an associative learning task. However, social network position was also related to cognitive performance. Individuals receiving aggressive interactions performed better, while those involved in aggressive interactions with more group members performed worse. Overall, this suggests that cognitive performance is related to specific types of social interaction. The findings from this study highlight the value of considering fine-grained metrics of sociality that capture the challenges associated with social life when testing the relationship between the social environment and cognition.

Timing of seasonal events is correlated with social network position in a wild mammal

Across animal systems, abiotic environmental features, including timing of seasonal events and weather patterns, affect fitness. An individual’s degree of social integration also has fitness consequences, but we lack an understanding of how abiotic features relate to patterns of individual sociality. A deeper understanding of this relationship could be developed from studying systems where these two links with fitness have already been identified. We explored the relationship between individual social behavior and seasonal timing, seasonal length, and weather patterns. We used social network analysis on a sixteen-year dataset of a wild population of hibernating yellow-bellied marmots (Marmota flaviventer). We fit a series of generalized linear mixed models and found that longer growing seasons before winter hibernation and longer winters were associated with increased individual sociality in the following spring. However, later snowmelt was associated with decreased sociality that spring. We found no relationship between individual sociality and various measures of precipitation and temperature. This suggests that seasonal timing and length may be a more important driver of sociality than weather patterns in this system, both as a lag and contemporary effect. Seasonal timing and length may mediate the opportunity or intensity of social interactions. The entwined relationships between the seasonal schedule and weather, and the seemingly contradictory role of winter length and snowmelt, suggests the timing of seasons and its relationship with sociality is complex and further exploration of environment-sociality relationships is required across taxa.Significance statementWhile the adaptive benefits of social behavior are well studied, less is known about how features of the abiotic environment drive variation in individual social behavior. Given increasing stochasticity in the timing of seasonal events and weather patterns, mapping the environment-sociality relationship will provide important insights to the drivers of sociality in the wild. This is particularly salient for species most vulnerable to climate and environmental change, such as seasonal hibernators, like yellow-bellied marmots (Marmota flaviventer). We found that features of seasonal duration were positively associated with increased sociality, whereas the timing of seasonal onset was negatively associated. This work provides empirical evidence towards an important gap in the behavioral ecology literature.

Analyzing the Impact of Social Network Position on Firm Performance: A Comprehensive Study

This study attempts to clarify the complex relationship that exists between social networks and corporate performance by introducing price and selling capacities as well as trust as a mediating component. A structural equation model was created using the body of existing research as a basis, and 380 small and medium-sized businesses (SMEs) in Indonesia participated in a survey to provide empirical data. The results show that, in the absence of social network trust, the use of social media in the management process by itself has no effect on the performance of the company. It becomes clear that trust is a major accelerator for the growth of selling and pricing skills, which in turn improves company performance. The survey highlights how important selling and pricing skills are when it comes to using social media, especially when it comes to developing trust. Although the research mostly focuses on small-to-medium-sized businesses and offers insightful information, generalizability to other contexts should be handled cautiously. In order to improve selling skills and expand corporate networks, managers should proactively use social media to improve overall company performance. In conclusion, trust is shown to be a critical mediator between social networks and corporate performance, emphasizing the need for trust in utilizing social media for better management and overall business success.

The interplay of social capital, faith, and offender resettlement

PurposeThis paper aims to explore the intricate relationship between social capital, faith and prison-leaver resettlement, emphasising how penal voluntary sector organisations (PVSOs) aid prison-leavers in their resettlement and desistance journeys, following incarceration.Design/methodology/approachEmploying a combination of narrative and thematic analysis, data was collected from 20 prison-leavers in England through semi-structured interviews. Purposive and snowball sampling was used to recruit participants from various community-based resettlement settings.FindingsThematic analysis revealed the emergence of faith in various iterations in facilitating desistance, Transforming Rehabilitation failure, identity transformation of the prison-leaver, the role of social capital in effective resettlement and the importance of PVSOs. In particular, the findings demonstrate the vital role of a “Faith Anchor”, defined in this paper as a trust-based relationship with an individual or spiritual entity, in facilitating desistance. This paper argues the need to recognise and fully integrate social capital building, faith and specialised support from PVSOs, as essential components of successful offender resettlement and desistance journeys.Research limitations/implicationsThe study considers the connection between faith, social capital and offender resettlement. Although demonstrating the role of faith in positive change and community engagement, there are limitations. Primarily, by exclusively recruiting participants through PVSOs, it might overlook varied resettlement experiences. Additionally, measuring desistance is complex and is limited by some academic views that it centres around abstinence. Although small-scale saturation was reached; generalisation should be approached with caution. Notably, post-Transforming Rehabilitation, the human cost of resettlement gaps became evident. Future research could benefit from a longitudinal lens, tracing desistance beyond initial PVSO interactions and offering richer, longitudinal insights.Practical implicationsSignificance of “faith anchors”: A “faith anchor” aids the desistance process. Integrating faith in resettlement offers emotional support for prison leavers. Value of social capital: It is pivotal for offender resettlement. Positive social networks are key for successful reintegration. Role of PVSOs: They provide vital resettlement support. Enhanced collaboration can optimise assistance for prison leavers. Addressing current system shortcomings: Rectifying the effects of Transforming Rehabilitation ensures holistic support, catering to prison leavers’ needs. Concept of “faith exchange”: Merging faith and support offers tailored resettlement approaches, fostering effective reintegration.Social implicationsThe study underscores the social implications of effective offender resettlement strategies. The integration of “faith anchors” and social capital aids in the personal rehabilitation of prison leavers and also supports community cohesion. By acknowledging faith as indictive to building trust-based relationships, communities can reduce the stigma associated with former offenders, promoting inclusivity and understanding. Additionally, the essential role of PVSOs highlights the value of community-driven initiatives in supporting reintegration. A combined approach that combines faith, social capital and community support can reshape societal perspectives on desistance, encouraging a more inclusive and empathetic approach to offender reintegration.Originality/valueThe insights gained contribute to the evolving discourse on prison-leaver resettlement and desistance and uniquely highlight the potential of a combined approach between social capital, faith and voluntary sector support, in achieving desistance goals. The term “faith exchange” emerges from this study as an original conceptual contribution, accentuating the relationship between faith and support in resettlement and desistance.

Effects of Trust, Public Engagement, Conflict, and Social Networks on Satisfaction with Ecological Restoration

River restoration is one of the most common, expensive, and environmentally influential forms of restoration, but has little post-restoration assessment of social success. In this study, we use social network theory and analysis (SNA), an emerging approach for understanding social dynamics in restoration projects, to examine the social connections, perceptions of project success, and attitudes of stakeholders involved in a river restoration project. We find that positive and negative social network ties have asymmetrical effects on stakeholders’ attitudes and satisfaction with project outcomes. Trust ties positively influence perceptions of public engagement, while avoidance ties negatively influence satisfaction. Trust in leaders positively influences satisfaction and both public engagement and perceived conflict influence the development of that trust. We contribute to the growing body of research using SNA in natural resource contexts through quantitative tests of social networks’ effects on stakeholder satisfaction with project outcomes.

The Power, Capacity, and Resiliency of Women in Substance Use Disorder Recovery to Overcome Multiple and Complex Housing Transitions

Gendered understandings of housing transitions amongst women and especially amongst those in substance use disorder recovery are under-researched. To address this gap, this study explores the multifaceted challenges and pathways to housing stability amongst women in substance use disorder recovery in the UK. Through qualitative analysis of life course interviews with 15 women in recovery, it becomes evident that housing insecurity, instability, and frequent transitions are common experiences. The women in the sample faced housing instability, ranging from temporary supported accommodations to homelessness. Notably, escaping negative relationships with male partners emerged as a primary cause of homelessness among these women. What this article highlights, which has not been found elsewhere to date, is that housing transitions are essentially a social process for women in recovery. This study highlights the social dimension of housing transitions. The potency of social capital and social networks in determining housing stability and security amongst women is emphasised as they exchange negative forms of social capital for positive forms of social capital. Recommendations stemming from this study include the need for drug recovery and housing policies to integrate gender-specific strategies to adequately support women in recovery. Further, they need to adopt a broader perspective, emphasizing the importance of fostering positive social connections and networks when considering housing options for individuals in recovery. For women who have spent a long time in supported residential and therapeutic environments, there is a need to develop a scaffolded support system to help women transition to independent living. The utilisation of recovery capital (and CHIME) as frameworks may provide a basis upon which to map out holistic and sustainable pathways to housing stability and security for women in recovery due to their acknowledgement of interconnected and related life domains that produce change and transformation.

A Purposeful Approach to LMX Differentiation: The Role of LMX With Key Members

A central idea in the leader-member exchange (LMX) literature is that leaders, due to the limited organizational and personal resources available to them, often struggle with developing and maintaining high-quality exchange relationships with all of their members. As a natural consequence, leaders typically form high-quality relationships with a select few members—often those who seem likable or are similar to the leader—while maintaining formal and distant relationships (i.e., low-quality LMX) with others. This form of differentiated treatment of members creates tensions in team dynamics. In this paper, we propose that leaders can mitigate the downsides of leader-member exchange differentiation (LMXD) for team dynamics by being more purposeful and strategic in how they differentiate in their treatment of members. Specifically, we posit that when leaders strategically develop high-quality LMX relationships with key members—individuals occupying influential positions in team social networks—such key members will engage in behaviors that buffer the negative impact of LMXD on team dynamics. Our framework integrates LMX theory with perspectives from social networks research to illustrate how strategic differentiation influences task and relational team dynamics. Finally, we discuss recommendations for empirically testing, theoretical extensions, and practical implications of this framework.

Natal legacies cause social and spatial marginalization during dispersal.

Early-life experiences can drive subsequent variation in social behaviours, but how differences among individuals emerge remains unknown. We combined experimental manipulations with GPS-tracking to investigate the pathways through which developmental conditions affect social network position during the early dispersal of wild red kites (Milvus milvus). Across 211 juveniles from 140 broods, last-hatched chicks-the least competitive-had the fewest number of peer encounters after fledging. However, when food supplemented, they had more encounters than all others. Using 4425 bird-days of GPS data, we revealed that this was driven by differential responses to competition, with less competitive individuals naturally spreading out into marginal areas, and clustering in central foraging areas when food supplemented. Our results suggest that early-life adversities can cause significant natal legacies on individual behaviour beyond independence, with potentially far-reaching consequences on the social and spatial structure of animal populations.

The influence of feeding station location on the space use and behavior of reintroduced 'alalā: Causes and consequences

AbstractSupplemental feeding is a common soft‐release strategy for increasing settlement, survival, and breeding in animals after translocation. However, supplemental feeding can also hinder natural patterns of dispersal or influence social interactions. Some drawbacks of feeding can be mitigated if feeding stations can function as management tools for directing animals' movement, for example, by guiding them toward wild food resources or prospective territories while directing them away from potential threats, for example, predator hotspots or urban/agricultural centers. However, these effects may not work equally across individuals or habitat types. For species such as 'alalā (Corvus hawaiiensis), Hawaii's last living corvid, being able to manipulate space use via supplemental feeders could improve reintroduction outcomes. We determined if and how feeding stations influence a released population of 'alalā by strategically moving feeders across varying distances and habitat types, while measuring how quickly birds discovered new feeders and how their space use changed. We found that 'alalā discovered feeders more rapidly in closed as opposed to open canopy habitat, and feeder movement influenced how far 'alalā ranged, especially in afternoon periods. Sex, social network position, and individual home range size did not predict feeder discovery. These insights offer lessons for using supplemental feeding when managing reintroductions.

Factors associated with the variation and consistency of social network position in group-housed calves

Gregarious animals often choose to interact with other individuals based on characteristics such as sex, age, and body size. However, we know little about the social structure and development of group-housed dairy calves. The aim of this study was to determine factors influencing a calves’ social network position and assess individual consistency over time. Holstein calves were group-housed (9 groups; 10 calves/group) at 15 ± 2.9 d of age (mean ± SD). Calves were weaned over 10 d beginning at 47 ± 2.5 d of age (mean ± SD) and remained in the study until 1 week after weaning. Continuous positional data were recorded within the pen using an ultra-wideband positioning system. Non-directed weighted matrices representing the social networks of calves (heifer: n = 55; bull: n= 32; excluded calves: n = 3) were constructed for each group consisting of consecutive 4-day periods per week over a total of 6 weeks. Social network position was measured using three centrality measures: strength, eigenvector, and closeness. To determine the factors that influence social structure, LMMs were used to test fixed effects of sex, ADG, age at grouping, season (warm or cool), and stage of development (pre-weaning, weaning, and post-weaning), with group and calf ID as nested random factors. Sex, weekly ADG, age at grouping, and season weren’t significant predictors of strength centrality. However, stage of development was a significant predictor for strength (p <.001) and closeness centrality (p <.001), with the highest scores found during the pre-weaning period and lowest during post-weaning. This suggests that calves were associating with more individuals in the early weeks of group formation and were more discerning with social interactions as time went on. The only predictor for eigenvector centrality was season (p =.04), with calves exhibiting higher eigenvector centrality during the cooler months. Strength and closeness centrality measures were significantly repeatable across weekly social networks for all groups (strength: R = 0.31 - R = 0.85, closeness: R = 0.27 - R = 0.89) and consistent across stage of development for 6 of the 9 groups (strength: R = 0.38 - R = 0.80, closeness: R = 0.33 - R = 0.87). Our results suggest that the amount of time spent within a group may play a role in shaping associations in dairy calves, but that dynamics of sociality and network structure may also be driven by individual and life-history traits.

“We are not all gangbangers”: Youth in high-poverty urban U.S. communities of color describe their attitudes toward violence, struggles, and resilience

ABSTRACT Centering youth voices in a participatory cross-age mentoring program in urban high-poverty communities, this paper addresses three problems in knowledge about youth of color experiencing low-income: 1) Misrepresenting youth as disproportionately violence-prone, 2) minimizing stressors youth experience, and 3) ignoring youths’ goals. Those knowledge problems can be framed as a contemporary form of DuBois’ construct of “scientific racism.” To counteract scientific racism, promote epistemic justice, and support youths’ goals of demonstrating they are not “all gangbangers,” this study reports data from a cross-age mentoring program about youths’ beliefs about aggression, attitudes towards violence and gangs, stress experiences, and goals expressed in field notes and letters. Most of the 549 control group and intervention youth strongly repudiated violence and gangs. Youth participating in the intervention as mentors and mentees were revolted by societal racism, community violence and police assaults. They reported many more stressors than any U.S subculture and regarded racism and obstacles against exiting poverty as tightly interwoven and formidable. Unlike privileged youth, for these youth the central element in their resilience was survival, framed as collective struggle. Demonstrating their cultural wealth, mentors and mentees aspired to academic and personal competence and sought closeness and collective uplift. To match youths’ needs and goals, intervention providers and researchers should focus on developing positive social networks, provide survival resources and stress management, support youths’ academic and employment goals, and afford youth maximal participation and self-expression.

Predictors of Early Treatment Termination in Patients Detained under §64 StGB - A Literature Review

The treatment of addicted offenders detained under § 64 of the German Criminal Code can be terminated prematurely. There is an extensive literature on predictors of such premature termination concerned with factors established before treatment. The aim of this paper is to present predictors of premature termination that become apparent during the course of therapy. We conducted a systematic literature search and included 16 publications. Patients and therapists rated impulsivity/aggressiveness, substance use relapses and a lack of patient-therapist relationship as negative predictors. Both groups assessed as beneficial the presence of motivation and a positive social network. To prevent early treatment termination a positive patient-therapist relationship, motivation and working through incidents during therapy is essential.

What you have, not who you know: food-enhanced social capital and changes in social behavioural relationships in a non-human primate.

Social network position in non-human primates has far-reaching fitness consequences. Critically, social networks are both heterogeneous and dynamic, meaning an individual's current network position is likely to change due to both intrinsic and extrinsic factors. However, our understanding of the drivers of changes in social network position is largely confined to opportunistic studies. Experimental research on the consequences of in situ, controlled network perturbations is limited. Here we conducted a food-based experiment in rhesus macaques to assess whether allowing an individual the ability to provide high-quality food to her group changed her social behavioural relationships. We considered both her social network position across five behavioural networks, as well as her dominance and kin interactions. We found that gaining control over a preferential food resource had far-reaching social consequences. There was an increase in both submission and aggression centrality and changes in the socio-demographic characteristics of her agonistic interaction partners. Further, we found that her grooming balance shifted in her favour as she received more grooming than she gave. Together, these results provide a novel, preliminary insight into how in situ, experimental manipulations can modify social network position and point to broader network-level shifts in both social capital and social power.
