Gut microbiota influence neurodevelopment of brain and programing of behaviors. However, the mechanism underlining the relationship between shoals' behaviors and intestinal microbiota remain controversial and the roles of neurotransmitters are still unclear. Here we show that, shoaling behavior affected the innate color preference of shoals, indicating that shoals tended to choose a favorable color environment that benefits social contact. Meanwhile, administration of D1-R antagonist disrupted the social interaction which led to the deficits of color preference. More importantly, the altered microbiota caused by an antibiotic OTC decreased the sociability and weakened shoals' color preference. When given a supplement of LGG after OTC exposure, fish exhibited an unexpectedly recovery capability in social cohesion and color preference. Our findings show that dopamine level of brain could mediate both social recognition and color preference, and highlight the pathway of microbial metabolites through the microbiota-gut-brain axis that coordinate the production of dopamine.

Research to assess the relationship between cats and humans is in a nascent stage. Some studies have assessed the stress status in cats using physiological indicators, such as the cortisol hormone, but have not focused on the social interaction with humans. Moreover, the role of oxytocin secretion in the relationship between cats and humans remains unclear. In this study, we determined the possibility of quantifying the urinary concentration of oxytocin in cats and assessed the effects of social contact with humans on the levels of urinary oxytocin and cortisol metabolite. Four cats were subjected to two conditions, namely, social (control), and non-social (no social contact with humans) conditions. The levels of cortisol and oxytocin metabolite in urine samples from the cats in both conditions were determined using enzyme-linked immunosorbent assays. The urinary concentrations of cortisol and oxytocin under the non-social condition were significantly higher than those under the social condition. In addition, the concentration of oxytocin significantly correlated with that of cortisol in cats under the non-social condition. In this study, it was possible to quantify the concentration of oxytocin in the urine of cats, and the obtained results suggest that cats recognize the social interaction with humans as important. This information might contribute to the establishment of an assessment method for the welfare of cats and might help in clarifying the relationship between cats and humans.

Abstract Background: Social contact in the early suckling period as an enriched social environment can reduce the aggressive behaviors of piglets at weaning regrouping, and improve their production performance and welfare. We speculated that the social environment could modulate the maturation of piglet intestinal microbiota at later growth stages. Therefore, we performed microbial 16S rRNA gene sequencing from fecal samples, collected at 16, 35, 42, and 63 days of age, to investigate the structure and function of intestinal microbiota in piglets that experienced early social contact. Results: The results showed that the litter weight of the piglets was not significantly different between the control (CON) and social contact (SC) groups at 35 days of age (P > 0.05), but the weight of piglets in the SC group significantly decreased at 63 days compared to the CON group (P < 0.05). While the proportion of Firmicutes were the most abundant bacterial phylum detected in both groups at all times, the proportion of Firmicutes and the Firmicutes-to-Bacteroides ratio were significantly higher in the SC group compared to the CON group and the proportion of Bacteroides was lower in the SC group compared to the CON group at 35, 42, and 63 days of age (P < 0.05). At the genus level, early social contact had a significant positive effect on the level of Lactobacillus at 35 and 42 days of age (P < 0.05), but a negative effect on Prevotella at 35, 42, and 63 days of age (P < 0.05). Furthermore, functional analysis of the microbial composition showed that the changes induced by early social contact mainly altered the relative abundance of metabolic and related pathways. From 35 days of age, the social contact notably had a negative effect on the abundance microbial pathways for protein digestion and absorption and lipid metabolism (P < 0.05). Conclusions: Early social contact truly changed the taxonomy of fecal microbiota in piglets, which in turn, impacted the potential for microbial function within the piglet intestine. At present, we speculate that providing continuous social contact negatively influences the nutrient metabolism for the growing piglets.

An increasing body of research has revealed that social behavior shapes the animal gut microbiome community and leads to the similarity among the same social group. However, some additional factors (e.g., diet and habitat within each social group) may also contribute to this similarity within the social group and dissimilarity between social groups. Here, we investigated the potential correlation between social behavior and the gut microbiome community in 179 musk deer from four breeding regions in the Maerkang Captive Center, Sichuan. The dominant gut microbiome phyla in the musk deer in this study were Firmicutes, Bacteroidetes, and Proteobacteria. We found significant effects on the alpha and beta diversity of the gut microbiome due to the breeding regions. The similarity within breeding regions was higher than that between the breeding regions. Due to their solitary lifestyle, captive musk deer are raised in single cages with no direct social contact most of the time. Deer in all of the breeding regions have the same diet and similar living conditions. However, during each mating season from November to January, in each region, one adult male and about six adult females will be put together into a large cage. Social behavior happens during cohabitation, including mating behavior, grooming within the same sex or between different sexes, and other social contact. Therefore, we speculated that high similarity within the breeding region might be associated with the social behavior during the mating season. This was a simple and straightforward example of the relationship between animal social behavior and the gut microbiome.

This chapter explores in how far Web 2.0, Weblogs in particular, has changed foreign language learning. It argues that Weblogs, along with Web 2.0, have created new genres for which users need new forms of literacy. A qualitative study on the relationship between the online audience of Web 2.0 and learners’ writing processes is presented and the findings are discussed. The study supports the assumption that learners are aware of the social interaction taking place through weblogs and that this awareness of audience influences the writing process. The author’s intention is to point out that Web 2.0 has created new communities of language practice and that foreign language learning is happening in these discourse communities through social interaction. The challenge in foreign language education is to integrate these communities of practice into the foreign language classroom.

Background Neonatal exposure to anesthetics that block N-methyl-D-aspartate receptors and/or hyperactivate gamma-aminobutyric acid type A receptor has been shown to cause neuronal degeneration in the developing brain, leading to functional deficits later in adulthood. The authors investigated whether exposure of neonatal mice to inhaled sevoflurane causes deficits in social behavior as well as learning disabilities. Methods Six-day-old C57BL/6 mice were exposed to 3% sevoflurane for 6 h. Activated cleaved caspase-3 immunohistochemical staining was used for detection of apoptosis. Cognitive functions were tested by pavlovian conditioned fear test. Social behavior was tested by social recognition and interaction tests. Results Neonatal exposure to sevoflurane significantly increased the number of apoptotic cells in the brain immediately after anesthesia. It caused persistent learning deficits later in adulthood as evidenced by decreased freezing response in both contextual and cued fear conditioning. The social recognition test demonstrated that mice with neonatal exposure to sevoflurane did not develop social memory. Furthermore, these mice showed decreased interactions with a social target compared with controls in the social interaction test, indicating a social interaction deficit. The authors did not attribute these abnormalities in social behavior to impairments of general interest in novelty or olfactory sensation, because they did not detect significant differences in the test for novel inanimate object interaction or for olfaction. Conclusions This study shows that exposure of neonatal mice to inhaled sevoflurane could cause not only learning deficits but also abnormal social behaviors resembling autism spectrum disorder.

There is a body of opinion which regards psychiatrically ill individuals, or at least one great class or subdivision of them, as suffering primarily from disturbances in personal relationships and social interaction processes generally. Sullivan, Horney and Fromm have made the most significant theoretical contributions to this subject, and empirical applications have been reported by Balint (1957), Maxwell Jones (1968), Rapoport (1960) and Laing (1961). These writers have at least this in common, that they take the point of view that since the pathology of the illness lies in social relationships the fundamental treatment process must lie there also—must, in fact, consist of re-experiencing social interaction within a therapeutic re-educative framework. In the past attention has been directed principally to the doctor-patient relationship as a heuristic model of social interaction, but Rapoport has extended the operational range of significant interaction to include all staff-patient, staff-staff and patient-patient encounters. As the recent Subcommittee of the Central Health Services Council has pointed out (1968), little has been written of the nurse as therapist, but a considerable literature has accumulated concerning the role of the social worker or caseworker or counsellor (e.g. Halmos, 1965). Halmos investigates the nature of such relationships, and finds therapeutic utility to be unrelated to intellectual skills. The therapeutic process is adjudged to lie in the relationship, true enough, but the essential qualities have more to do with the interpersonal styles of the therapist, than with his analytical expertise. Such is his conclusion. Apparently social skills are necessary for the professional worker, but intellectual skills for the problems to be unravelled are of little importance, and are largely irrelevant.

We employ cortical mesoscale calcium-imaging to observe brain activity in two head-fixed mice in a staged social touch-like interaction. Using a rail system, mice are brought together to a distance where macrovibrissae of each mouse make contact. Cortical signals were recorded from both mice simultaneously before, during, and after the social contact period. When the mice were together, we observed bouts of mutual whisking and cross-mouse correlated cortical activity in the vibrissae cortex. This correlated activity was specific to individual interactions as the correlations fell in trial-shuffled mouse pairs. Whisk-related global GCAMP6s signals were greater in cagemate pairs during the together period. The effects of social interaction extend outside of regions associated with mutual touch and had global synchronizing effects on cortical activity. We present an open-source platform to investigate the neurobiology of social interaction by including mechanical drawings, protocols, and software necessary for others to extend this work.

Pesantren (Islamic boarding school) as islamic educational institution in general organizes and designs curriculum that able to avoid its students from sexual behavior that contrast to the islamic values, as well as in pesantren or after graduating from pesantren. One of the effort of pesntren to reach such goal among them are by organizing the relationship between sexs and to separate its students according to the sexs. Students are faced to the situation that different at all with the actual reality. Some aspects are regarded can direct to the social contact between sexs are controlled. The question appears about how the influence of the sexs separation (single sex-pesantren) to the student sexual development, as they coming out from that pesantren and must face the actual reality, which heterogenous, uncontrollabe and different at all with the relaity that experienced in pesantren.

This paper presents an analysis of the death rituals carried out by Muslims in the Priangan region known as ngajahul. Ngajahul is done on the sixth or seventh day after death. Analysis of the ritual of death illustrates that the ritual of death is not only a spiritual-fiqhiyyah aspect, but also has a role in describing social relations. The graveyard that lay in the cemetery, not only shows the grave, but also describes the relationship between the deceased, the family and the social environment. This research in a sociological perspective produces the concept that the rituals of death and society, especially Muslim societies in various aspects are referred to as containing social cohesion. This concept illustrates that death rituals are not as depicted in recitation forums that see death rituals as a tradition laden with rituals that are spiritually nuanced. Ngajahul is a tradition that produces social interaction and involvement in social life that is produced simultaneously. Key Words : Ngajahul, Ritual, Social cohesion, fiqhiyyah
