Abstract Allogrooming provides a window into the social lives of many group-living mammals and birds. The fitness benefits of allogrooming are encouraged by proximate mechanisms that make it physiologically rewarding for both actors and receivers. However, receivers might not always benefit from allogrooming. Some allogrooming decisions might be the actor’s response to cues of the recipient’s need. Other decisions might only be caused by the actor’s motivational state. To test these ideas, we studied what triggers allogrooming in common vampire bats. In test 1, subjects that had experimentally disturbed and wetted fur were more likely to be allogroomed, even when controlling for increased self-grooming. In test 2, allogrooming rates were elevated not only by receiver self-grooming (a cue for receiver need) but also by the actor’s previous self-grooming. Both effects were significantly greater than the effect of self-grooming by third parties. Interestingly, we detected a negative interaction: the positive effect of receiver need on allogrooming was smaller when the actor was previously self-grooming. This is consistent with the hypothesis that there are “receiver-driven” allogrooming decisions, which are responses to recipient need, and “actor-driven” decisions, which are not. We predict that receiver-driven allogrooming will bestow greater benefits to recipients compared with actor-driven allogrooming.

This article studies the contribution of exploitative and explorative innovation to the perceptions of economic and social value of local authorities in charge of sustainability-related innovation. The model proposed is tested capturing the perceptions of 656 local authorities. The research findings contribute evidence of complex linkages between innovation forms (i.e. exploitative and explorative) and facets of perceived value. Overall, the link between the perceptions of both forms of innovation and economic value fits March’s (1991) view. A positive effect of both exploitative and explorative innovation on economic value is found, coupled with a negative interaction effect. The influence of exploitative innovation is stronger than that of explorative innovation. However, this is only part of the story. We also consider the link between exploitative/explorative innovation and one additional facet of value: social value (in the form of network identification). The roles of both predictors are virtually opposite: identification is mostly explained by explorative innovation, rather than exploitative innovation. The social value dimension considered in this research adds an explanation as to why public organisations may focus on exploration or combine both exploitation and exploration. Points for practitioners • Public managers may focus on exploitative innovation (when economic value considerations are dominant) and on explorative innovation (when social value thinking prevails), or combine both activities. • Network promoters should not assume that public managers favour exploitative innovation over explorative innovation.

The ‘social microbiome’ can fundamentally shape the costs and benefits of group-living, but understanding social transmission of microbes in free-living animals is challenging due to confounding effects of kinship and shared environments (e.g. highly associated individuals often share the same spaces, food and water). Here, we report evidence for convergence towards a social microbiome among introduced common vampire bats, Desmodus rotundus , a highly social species in which adults feed only on blood, and engage in both mouth-to-body allogrooming and mouth-to-mouth regurgitated food sharing. Shotgun sequencing of samples from six zoos in the USA, 15 wild-caught bats from a colony in Belize and 31 bats from three colonies in Panama showed that faecal microbiomes were more similar within colonies than between colonies. To assess microbial transmission, we created an experimentally merged group of the Panama bats from the three distant sites by housing these bats together for four months. In this merged colony, we found evidence that dyadic gut microbiome similarity increased with both clustering and oral contact, leading to microbiome convergence among introduced bats. Our findings demonstrate that social interactions shape microbiome similarity even when controlling for past social history, kinship, environment and diet.

Social behaviour in solitary carnivores has long been an active area of investigation but for many species remains largely founded in conjecture compared to our understanding of sociality in group-living species. The social organization of the wolverine has, until now, received little attention beyond its portrayal as a typical mustelid social system. In this chapter the authors compile observations of social interactions from multiple wolverine field studies, which are integrated into an ecological framework. An ethological model for the wolverine is proposed that reveals an intricate social organization, which is driven by variable resource availability within extremely large territories and supports social behaviour that underpins offspring development.

Inspired by recent epistemological and ontological debates aimed at unsettling and reshaping conceptions of language, this essay discusses how mainstream sociolinguistics offers notions meaningful for studying contexts of the South. Based on empirical studies of youth in two African cities, Yaoundé in Cameroon and Maputo in Mozambique, the essay engages with “fluid modernity” and “enregisterment” to unravel the role that fluid multilingual practices play in the social lives of urban youth. The empirically grounded theoretical discussion shows how recent epistemologies and ontologies offer inroads to more pluriversal knowledge production. The essay foregrounds: i) the role of language in the sociopolitical battles of control over resources, and ii) speakers’ reflexivity and metapragmatic awareness of register formations of fluid multilingual practices. Moreover, it shows how bundles of localized meanings construct belongings and counterhegemonic discourses, as well as demonstrating speakers’ differential valuations and perceptions of boundaries and transgressions across social space.

AbstractIn 2014 through 2018, Sichuan Provincial Institute of Cultural Relics and Archaeology and History Museum of Quxian County conducted a systematic archaeological survey, detection, and excavation to the Chengba site in Quxian County. The excavation uncovered 4,000sq m in total, from which 444 various features were recovered and over 1,000 artifacts were unearthed. The functional zoning of this site has been roughly made clear; the excavations of the western gate and important building foundations of the Guojiatai city site are important archaeological discoveries of the city sites of the Han through Western Jin dynasties, and at the checkpoint site on the waterway of this period was uncovered for the first time in China. The large amounts of bamboo slips and wooden tablets unearthed in the excavation provided important materials for the explorations on the management of the central government of the Han and Jin empires to the administrative areas of commandery and district levels and the social lives of the local people at that time.

The objective of this study was to understand the impact of the opioid overdose epidemic on the social lives of people suffering from chronic pain, focusing on interactions within their personal and professional circles. The study was based on 22 in-depth interviews with people living with chronic pain in Canada. Using thematic analysis, we documented three main impacts of the opioid overdose epidemic: (a) increased worries of people in pain and their families regarding the dangers of opioids; (b) prejudices, stigma, and discrimination faced during conversations about opioids; and (c) stigma management attempts, which include self-advocacy and concealment of opioid use. This study represents important knowledge advancement on how people manage stigma and communicate about chronic disease during everyday life interactions. By showing negative effects of the epidemic’s media coverage on the social experiences of people with chronic pain, we underscore needs for destigmatizing approaches in public communication regarding opioids.

AbstractBy using multiple satellite measurements, the changes of the aerosol optical depth (AOD) and nitrogen dioxide (NO2) over South Korea were investigated from January to March 2020 to evaluate the COVID-19 effect on the regional air quality. The NO2 decrease in South Korea was found but not significant, which indicates the effects of spontaneous social distancing under the maintenance of ordinary life. The AODs in 2020 were normally high in January, but they became lower starting from February. Since the atmosphere over Eastern Asia was unusually stagnant in January and February 2020, the AOD decrease in February 2020 clearly reveals the positive effect of the COVID-19. Considering the insignificant NO2 decrease in South Korea and the relatively long lifetime of aerosols, the AOD decrease in South Korea may be more attributed to the improvement of the air quality in neighboring countries. In March, regional atmosphere became well mixed and ventilated over South Korea, contributing to large enhancement of air quality. While the social activity was reduced after the COVID-19 outbreak, the regional meteorology should be also examined significantly to avoid the biased evaluation of the social impact on the change of the regional air quality.

Cooperation among non-kin is well documented in humans and widespread in non-human animals, but explaining the occurrence of cooperation in the absence of inclusive fitness benefits has proven a significant challenge. Current theoretical explanations converge on a single point: cooperators can prevail when they cluster in social space. However, we know very little about the real-world mechanisms that drive such clustering, particularly in systems where cognitive limitations make it unlikely that mechanisms such as score keeping and reputation are at play. Here, we show that Trinidadian guppies ( Poecilia reticulata ) use a ‘walk away’ strategy, a simple social heuristic by which assortment by cooperativeness can come about among mobile agents. Guppies cooperate during predator inspection and we found that when experiencing defection in this context, individuals prefer to move to a new social environment, despite having no prior information about this new social group. Our results provide evidence in non-human animals that individuals use a simple social partner updating strategy in response to defection, supporting theoretical work applying heuristics to understanding the proximate mechanisms underpinning the evolution of cooperation among non-kin.
