Testing individual motivations for social activity in violation of the mandated lockdown regime is a challenging research topic for evolutionary psychology. To this purpose, we analyzed twenty popular weekly routes and the potential impact of sex and relationship status (single versus coupled) on the reported level of spatial-social activity during the quarantine in Russia between March and June 2020 (N = 492). Our study revealed a significant difference between men’s and women’s mobility: men, in general, tend to exhibit substantially higher spatial activity. The results have shown that individuals living on their own have more social interactions with friends and exhibit more profound spatial mobility via public transport. On the other hand, spatial activity of coupled individuals of both sexes were mostly devoted to solving a list of economic and matrimonial tasks. At the same time, men already cohabiting with a partner leave their homes for dating purposes more frequently than single men and women. We interpret these findings in the sense that both individual and sex-specific differences in observed sociality could be a result of a fine-tuned adaptive populational response to a contemporary virus threat, predominantly rooted in the evolution of behavioral strategies in the reproductive and economic spheres of each sex. Indeed, unlike women, coupled men have been preserving highly risky and intense social behavior during the COVID-19 pandemic.

Social impairment is a cardinal feature of schizophrenia spectrum disorders (SZ). Smaller social network size, diminished social skills, and loneliness are highly prevalent. Existing, gold-standard assessments of social impairment in SZ often rely on self-reported information that depends on retrospective recall and detailed accounts of complex social behaviors. This is particularly problematic in people with SZ given characteristic cognitive impairments and reduced insight. Ecological Momentary Assessment (EMA; repeated self-reports completed in the context of daily life) allows for the measurement of social behavior as it occurs in vivo, yet still relies on participant input. Momentary characterization of behavior using smartphone sensors (e.g., GPS, microphone) may also provide ecologically valid indicators of social functioning. In the current study we tested associations between both active (e.g., EMA-reported number of interactions) and passive (GPS-based mobility, conversations captured by microphone) smartphone-based measures of social activity and measures of social functioning and loneliness to examine the promise of such measures for understanding social impairment in SZ. Our results indicate that passive markers of mobility were more consistently associated with EMA measures of social behavior in controls than in people with SZ. Furthermore, dispositional loneliness showed associations with mobility metrics in both groups, while general social functioning was less related to these metrics. Finally, interactions detected in the ambient audio were more tied to social functioning in SZ than in controls. Findings speak to the promise of smartphone-based digital phenotyping as an approach to understanding objective markers of social activity in people with and without schizophrenia.

AbstractAngelman syndrome (AS) is a genetic neurodevelopmental disorder due to the absence of the E3-ligase protein, UBE3A. Inappropriate social interactions, usually hyper-sociability, is a part of that syndrome. In addition, clinical surveys and case reports describe aggressive behavior in AS individuals as a severe difficulty for caretakers. A mouse model for AS recapitulates most of the human AS phenotypes. However, very few studies utilized this mouse model for investigating affiliative social behavior, and not even a single study examined aggressive behavior. Hence, the aim of the herein study was to examine affiliative and aggressive social behavior. For that, we utilized a battery of behavioral paradigms, and performed detailed analyses of these behaviors. AS mice exhibited a unique characteristic of reduced habituation towards a social stimulus in comparison to their wild-type (WT) littermates. However, overall there were no additional marked differences in affiliative social behavior. In contrast to the mild changes in affiliative behavior, there was a striking enhanced aggression in the AS mice compared to their WT littermates. The herein findings emphasize the use of AS mouse model in characterizing and measuring inappropriate aggressive behavior, and suggests these as tools for investigating therapeutic interventions aimed at attenuating aggressive behavior.

Abstract1. The relation between the social behavior and the electrical emissions of Gymnotus carapo is examined. 2. Members of the species Gymnotus carapo approach certain sources of electrical stimuli and, in a statistically significant number of instances, assume a stance parallel to the plane from which the stimuli originate. 3. The approach and postural responses elicited by electrical cues resemble those observed when two fish, placed in the same tank, interact socially. 4. Electrical cues therefore appear to facilitate certain social interactions in Gymnotus carapo. 5. The character of electrical emission in Gymnotus carapo appears to change as a function of certain social interaction: a. Interaction resembling aggression is accompanied by brief increases in the frequency of emission. b. The increases in frequency appear to be linked to thrusting movements. c. Fish interacting with one another appear to lock into a common frequency more often than fish that are not in physical contact with one another. d. During social interaction, one of the two fish is occasionally observed to halt emissions altogether. 6. The exact significance of the social behavior observed in the context of the life history of Gymnotus carapo is unknown.

There may be conflict between the requirements of surgical training and those of the clinical service if training has an impact on clinical outcomes. One area of potential impact is perioperative blood loss. We compared total and 12-hour blood loss after 2,079 consecutive cardiac operations performed over 2 years by trainees and consultants. One- and two-way analyses of variance with EuroSCORE and surgeon status as factors were carried out to evaluate the impact of surgeon status on blood loss. There was no difference in blood loss between consultants and trainees. We also compared the rates between consultants and trainees of patients returning to the operating room due to bleeding. This showed a significant difference, with trainees having a higher rate of investigation for bleeding. Cardiac surgical training can be achieved without an adverse effect on blood loss, but it may be associated with a higher rate of re-intervention for bleeding.

Microbes influence a wide range of host social behaviors and vice versa. So far, however, the mechanisms underpinning these complex interactions remain poorly understood. In social animals, where individuals share microbes and interact around foods, the gut microbiota may have considerable consequences on host social interactions by acting upon the nutritional behavior of individual animals. Here we illustrate how conceptual advances in nutritional ecology can help the study of these processes and allow the formulation of new empirically testable predictions. First, we review key evidence showing that gut microbes influence the nutrition of individual animals, through modifications of their nutritional state and feeding decisions. Next, we describe how these microbial influences and their social consequences can be studied by modelling populations of hosts and their gut microbiota into a single conceptual framework derived from nutritional geometry. Our approach raises new perspectives for the study of holobiont nutrition and will facilitate theoretical and experimental research on the role of the gut microbiota in the mechanisms and evolution of social behavior.

The lack of social acceptance of handicapped students by their nonhandicapped peers has been cited as a major deterrent to the success of mainstreaming (Strain, 1982). While this problem has been recognized, there has been little empirical investigation of ways to deal with the social acceptance issue beyond direct training of the handicapped in appropriate social behavior development (Gresham 1981). The primary purpose of the present investigation was to examine the influence of training nonhandicapped students about individual differences on their social interactions with rejected handicapped students. The results of the investigation provide initial evidence that training nonhandicapped students about individual differences influences their social interactions with their rejected handicapped peers in a small group setting.

The aims of this research is to analyse about the differences of emotional lexicon used by male and female communication in South Kuta-Bali when they used Balinese language in their daily interaction.  The scope of male and female is closely related to the social behavior which includes the social identity of male and female in society and this becomes the basis of how the language is used in this context of social. This research is interested to uncover more how people use language in terms of expressing their emotional in social interaction. This study is a sociolinguistic approach used the theory from Hickey, Raymon (2010). The data source in this study is the south Kuta community who use Balinese language in social interactions. The Data collection is done by observation, interview, recording and note taking and descriptive qualitative method is applied to analyze the data. The result of the analysis found that the emotional lexical is used by the male and female in their social interaction, it could mention that both Augmentatives and Euphemisms is used by male and female in their social interaction however the augmentative is mostly used by female in informal occasion. Balinese female often used prohibition instead of imperative in expressing her idea about ordering someone to do something. In the other hand, the male directly used imperative sentence in ordering something. He usually does not use many awkwardness to say his point in a conversation. This may be considered that the male often go to the straight point when expressing his idea. Keywords: Emotional Lexicon, Male and Female

Potential Impact

Despite the crucial role played by Nile perch in the income of fishers around Lake Victoria, Tanzania, fishing pressure has increased in recent years and has led to overfishing and, consequently, a risk to the lake’s future sustainability and the fishers’ livelihoods. This study used data collected in 2018 from 268 randomly selected sample fishers at 10 landing sites across Lake Victoria. In conjunction with the endogenous switching regression model, the potential impact of Nile perch overfishing on the fishers’ income per fishing trip in Lake Victoria was evaluated. The results show that there is a significant difference in the socio-economic, institutional and fishing effort characteristics of Nile perch fishers who overfish and those who do not. In particular, Nile perch fishers who overfish earn significantly higher incomes per fishing trip than fishers who do not overfish. The study recommends the need for policy makers to develop policies that acknowledge the dynamics of socio-economic, institutional and fishing effort factors. In addition, more flexible fish quota restrictions and consistent fishing patrols need to be enforced to ensure compliance with fishery regulations. These measures should promote a balance between the sustainability of fishery resources and an improved income for Nile perch fishers in Lake Victoria.

The advent of new technologies and statistical analyses has provided valuable insights into chondrichthyan social behavior. It has become apparent that sharks and rays lead more complex social lives than previously believed. Heterarchy combines hierarchy and social network theory and although it is not a new concept, it is rarely applied to animal social interactions. Here, we applied heterarchy to a case study involving smooth stingrays foraging for fish scraps at boat ramp in Jervis Bay, NSW Australia. We took advantage of their attraction to this site to examine their social behavior during agonistic interactions over the provisioned resource. We observed a stable, relatively linear but shallow dominance hierarchy that was highly transitive dominated by a single individual. Social network analysis revealed a non-random social network centered on the dominant individual. Contrary to previous research, size did not predict dominance, but it was correlated with network centrality. The factors determining dominance of lower ranks were difficult to discern, which is characteristic of despotic societies. This study provides the first heterarchical assessment of stingray sociality, and suggests this species is capable of complex social behavior. Given higher dominance and centrality relate to greater access to the provisioned resource, the observed social structure likely has fitness implications.
