Social Interaction With an Alcohol-Intoxicated or Cocaine-Injected Peer Selectively Alters Social Behaviors and Drinking in Adolescent Male and Female Rats.

Drinking alcohol is facilitated by social interactions with peers, especially during adolescence. The importance of peer social influences during adolescence on alcohol and substance use has recently received more attention. We have shown that social interaction with an alcohol-intoxicated peer influences adolescent alcohol drinking differently in male and female rats using the demonstrator-observer paradigm. The present set of experiments analyzed the social interaction session to determine changes in social behaviors and subsequent alcohol drinking in adolescent male and female rats. Specifically, in Experiment 1, we determined whether specific social behaviors were altered during interaction with an alcohol-intoxicated demonstrator administered 1.5g/kg ethanol (EtOH) and assessed changes in EtOH intake in adolescent observers. Experiment 2 examined changes in voluntary saccharin consumption to determine whether social interaction with an alcohol-intoxicated demonstrator administered 1.5g/kg EtOH altered consumption of a palatable solution. In Experiment 3, we administered saline, and a low (5mg/kg) or high (20mg/kg) dose of cocaine to the demonstrator and assessed changes in the adolescent observers to determine whether social interaction with a "drugged" peer altered social behaviors and voluntary EtOH intake. We showed that social interaction with an alcohol-intoxicated demonstrator administered 1.5g/kg EtOH (i) decreased social play and increased social investigation and social contact in adolescent male and female observers, (ii) did not alter nonsocial behaviors, (iii) did not alter saccharin consumption, and (iv) increased voluntary EtOH intake in adolescent female but not male observers. When the peer was injected with cocaine, (i) social play was dose-dependently decreased, (ii) there were no changes in other social or nonsocial behaviors, and (iii) voluntary EtOH intake in adolescent male and female observers was unaffected. The present results are consistent and extend our previous work, showing that social interaction with an alcohol-intoxicated peer selectively alters social behaviors and alcohol drinking in adolescent rats. Females appear to be more sensitive to the elevating effects of social interaction on voluntary EtOH consumption.

Corporate social responsibility behaviors and corporate reputation

PurposeThis paper aims to study how corporate social responsibility (CSR) behaviors can lead to corporate membership onFortuneMagazine’s Most Admired Companies list.Design/methodology/approachRegression analysis using environmental, social and governance (ESG) statistics published by MSCI-KLD as independent variables to predict the behaviors that lead to most admired status.FindingsNot surprisingly, corporate financial performance (CFP) is the largest contributor to membership on the list. However, after controlling for CFP, the analysis finds that specific social responsibility behaviors contribute to membership on the Fortune list.Practical implicationsThis paper finds that CSR behaviors are important to a firm’s reputation as measured byFortune’s Most Admired Companies list. Therefore, companies should continue with social responsibility activities to improve their reputation with investors.Originality/valueMany articles test the effect of ESG on financial performance and the role of financial performance on stock price. This paper is unique in that it measures the impact of CSR on corporate reputation using an important financial market benchmark – theFortuneMost Admired Companies list.

Social Behavior of Antibiotic Resistant Mutants Within Pseudomonas aeruginosa Biofilm Communities

The complex spatial structure and the heterogeneity within biofilms lead to the emergence of specific social behaviors. However, the impact of resistant mutants within bacterial communities is still mostly unknown. Thus, we determined whether antibiotic resistant mutants display selfish or altruistic behaviors in mixed Pseudomonas aeruginosa biofilms exposed to antibiotics. ECFP-tagged P. aeruginosa strain PAO1 and its EYFP-tagged derivatives hyperproducing the β-lactamase AmpC or the efflux pump MexAB-OprM were used to develop single or mixed biofilms. Mature biofilms were challenged with different concentrations of β-lactams to monitor biofilm structural dynamics, using confocal laser scanning microscopy (CLSM), and population dynamics, through enumeration of viable cells. While exposure of single wild-type PAO1 biofilms to β-lactams lead to a major reduction in bacterial load, it had little effect on biofilms formed by the resistant mutants. However, the most reveling finding was that bacterial load of wild-type PAO1 was significantly increased when growing in mixed biofilms compared to single biofilms. In agreement with CFU enumeration data, CLSM images revealed the amplification of the resistant mutants and their protection of susceptible populations. These findings show that mutants expressing diverse resistance mechanisms, including β-lactamases, but also, as evidenced for the first time, efflux pumps, protect the whole biofilm community, preserving susceptible populations from the effect of antibiotics. Thus, these results are a step forward to understanding antibiotic resistance dynamics in biofilms, as well as the population biology of bacterial pathogens in chronic infections, where the coexistence of susceptible and resistant variants is a hallmark.

Social comparisons, social media addiction, and social interaction: An examination of specific social media behaviors related to major depressive disorder in a millennial population

AbstractAlthough studies have shown that increases in the frequency of social media use may be associated with increases in depressive symptoms of individuals with depression, the current study aimed to identify specific social media behaviors related to major depressive disorder (MDD). Millennials (N = 504) who actively use Facebook, Twitter, Instagram, and/or Snapchat participated in an online survey assessing major depression and specific social media behaviors. Univariate and multivariate analyses were conducted to identify specific social media behaviors associated with the presence of MDD. The results identified five key social media factors associated with MDD. Individuals who were more likely to compare themselves to others better off than they were (p = 0.005), those who indicated that they would be more bothered by being tagged in unflattering pictures (p = 0.011), and those less likely to post pictures of themselves along with other people (p = 0.015) were more likely to meet the criteria for MDD. Participants following 300 + Twitter accounts were less likely to have MDD (p = 0.041), and those with higher scores on the Social Media Addiction scale were significantly more likely to meet the criteria for MDD (p = 0.031). Participating in negative social media behaviors is associated with a higher likelihood of having MDD. Research and clinical implications are considered.

Friendship and social functioning following early institutional rearing: The role of ADHD symptoms.

Early institutional rearing is associated with increased risk for subsequent peer relationship difficulties, but the underlying mechanisms have not been identified. Friendship characteristics, social behaviors with peers, normed assessments of social problems, and social cue use were assessed in 142 children (mean age = 10.06, SD = 2.02; range 7-13 years), of whom 67 were previously institutionalized (PI), and 75 were raised by their biological families. Anxiety and attention-deficit/hyperactivity disorder (ADHD) symptoms, often elevated among PI children, were examined as potential mediators of PI status and baseline social functioning and longitudinal follow-ups (2 and 4 years later). Twenty-seven percent of PI children fell above the Child Behavior Checklist Social Problems cutoff. An examination of specific social behaviors with peers indicated that PI and comparison children did not differ in empathic concern or peer social approach, though parents were more likely to endorse aggression/overarousal as a reason that PI children might struggle with friendships. Comparison children outperformed PI children in computerized testing of social cue use learning. Finally, across these measures, social difficulties exhibited in the PI group were mediated by ADHD symptoms with predicted social problems assessed 4 years later. These findings show that, when PI children struggle with friendships, mechanisms involving attention and behavior regulation are likely contributors.

Reciprocal Interactions Between Gut Microbiota and Host Social Behavior.

Animals harbor an extensive, dynamic microbial ecosystem in their gut. Gut microbiota (GM) supposedly modulate various host functions including fecundity, metabolism, immunity, cognition and behavior. Starting by analyzing the concept of the holobiont as a unit of selection, we highlight recent findings suggesting an intimate link between GM and animal social behavior. We consider two reciprocal emerging themes: (i) that GM influence host social behavior; and (ii) that social behavior and social structure shape the composition of the GM across individuals. We propose that, throughout a long history of coevolution, GM may have become involved in the modulation of their host’s sociality to foster their own transmission, while in turn social organization may have fine-tuned the transmission of beneficial endosymbionts and prevented pathogen infection. We suggest that investigating these reciprocal interactions can advance our understanding of sociality, from healthy and impaired social cognition to the evolution of specific social behaviors and societal structure.

Using a social story intervention to decrease inappropriate behavior of preschool children with autism

This research investigated the inappropriate behavior of preschool children with autism in a classroom and examined the effectiveness of the use of social stories to decrease inappropriate autistic behavior. An A-B-A-B single subject design was used across the five participants selected for the study. Investigating the problematic social skills and developing a social story intervention for the preschool autistic children was completed, followed by an examination of the effectiveness of the social story intervention. Ten common problematic social skills among the autistic children in preschool were identified—walking around, making loud noises, not sharing their toys with others, showing frustration when feeling unsatisfied, having no patience, not putting toys away when finished, taking other people's belongings without permission, not knowing how to greet others, destroying things when feeling frustrated, and giving a hug to other people at inappropriate times. It was found that the social story intervention helped to decrease inappropriate behavior in children with autism. The social story intervention consisted of five social story books and five e-books (one story per child) using a single subject design with an A-B-A-B pattern. The autistic children preferred social stories from the hardcopy books compared with stories from the e-books. A fourth stage time trial was used over 6 weeks, five times per week, for a total of 30 times. The findings suggested that the use of properly constructed social stories can be effective in decreasing the inappropriate behavior of children with autism. However, each story intervention should be applied with caution because of individual differences between children. The social story intervention should be designed only for autistic children who exhibit specific inappropriate social behavior.

Monoacylglycerol lipase inhibition alters social behavior in male and female rats after post-weaning social isolation

Post-weaning social isolation (PSI) has been shown to increase aggressive behavior and alter medial prefrontal cortex (mPFC) function in rats. The present study sought to determine whether this phenotype would be normalized by increasing levels of the endocannabinoid 2-arachidonoylglycerol (2-AG) using pharmacological inhibition of monoacylglycerol lipase (MAGL). Male and female Sprague-Dawley rats were exposed to either 4 weeks of PSI or social rearing (SR) starting on postnatal day 21, then underwent a 15 min trial of social interaction with a novel, same-sex juvenile rat. Rats were administered an acute injection of the MAGL inhibitor MJN110 or vehicle prior to the social interaction. Rats received either 0 mg/kg (vehicle), 1 mg/kg, or 5 mg/kg of MJN110. Both doses of MJN110 decreased aggressive grooming, a measure of agonistic behavior, in both males and females, largely driven by decreased aggressive grooming in PSI rats. There were no effects of MJN110 on overall social behavior or play behavior, while modest effects were observed on locomotor activity in SR rats only. While social interaction increased c-Fos expression in the mPFC of both males and females, MJN110 reduced c-Fos preferentially in females. These results suggest that 2-AG can modulate specific social behaviors during adolescence, and may affect mPFC function differentially in males and females.

Forming first impressions of children: the role of attention-deficit/hyperactivity disorder symptoms and emotion dysregulation.

Previous research on peer status of children with attention-deficit/hyperactivity disorder (ADHD) has focused on already-established peer groups, rendering the specific social behaviors that influence peers' initial impressions largely unknown. Recently, theorists have argued that emotion dysregulation is a key aspect of ADHD, with empirical work finding relations between emotion dysregulation and social outcomes. Therefore, the current study focuses on the initial interactions among children varying in ADHD symptoms duringh a novel playgroup, proposing that emotion dysregulation displayed during the playgroup may serve as a possible pathway between ADHD symptoms and peers' initial negative impressions. Participants were 233 elementary-age children ranging from 8 to 10years old (M=8.83, 70% male). Parents and teachers rated children's ADHD symptoms and related impairment; 51% of the children met criteria for an ADHD diagnosis. Then, children participated with unfamiliar peers in a three-hour playgroup that included three structured and two unstructured tasks. After the tasks, children and staff rated each child on social outcomes. Coders unaware of child's diagnostic status watched videos of the groups and rated each child's global emotion dysregulation during each task. Using multiple raters and methods, ADHD severity was associated with more negative peer ratings, through observed emotion dysregulation. Results were consistent for both parent and teacher ratings of ADHD severity as well as for both peer ratings of likeability and staff ratings of perceived peer likeability. When focusing on improving peers' initial impressions of children with ADHD symptoms, emotion dysregulation may be a valuable target for intervention.

“Political Correctness” from a “Border Reason”: Between Dignity and the Shadow of Exclusion

The concept of political correctness highlights a set of principles and structures that should (or, in other cases, must) be followed to pursue a specific social behavior that characterizes a society and endorses an ideal identity. Nevertheless, even when this behavior implies a sense of social recognition and acceptance by a specific group, it also encompasses a risk of imposing a particular model of life, halting the emergence of criticisms and differences as far as it could be misguided to promote discrimination and exclusion. All of these raise the question of whether it is possible to conceive political correctness from a perspective of inclusion that transcends this layer of exclusion. If this is the case, following Eugenio Trías’ philosophy about the limit, the concept needs to be reconsidered through a “border reason” that enables one to conceive the benefits it brings as well as the criticisms that come from the analysis of the “shadowy” practice of the concept. This approach will lead to accepting that political correctness fulfills a function for society but that it requires a reflexive attitude along with its practices as part of a border relation between its benefits and the risks that it also has to tackle. Finally, a concept that could serve as a hinge to reinforce the perspective of a border limit is dignity, which could lead to an ethical reflection that underpins politically correct actions.

Interviews, Disclosures, and Misperceptions: Autistic Adults' Perspectives on Employment Related Challenges

As increasing numbers of autistic adults are seeking and gaining employment, the experiences of autistic adults in the workplace is critical to consider. Autistic adults encounter a range of challenges in obtaining and keeping employment and often report a range of negative experiences in the workplace. The current research reports the results from a large, national exploratory study on the experiences of autistic adults in the workplace as well as their thoughts on how to improve these experiences for the autism community. In particular, participants reported challenges with the interviewing process, which requires very specific and consistent social behaviors, as well as with feeling comfortable disclosing one's autistic status at work. These challenges are often connected with public misperceptions about autism. The article discusses these challenges as well as strategies to improve autism-related understanding and awareness in the workplace. This work is critical to conversations about diversity in the workplace.

Warmth and competence as distinct dimensions of value in social emotions.

Gervais & Fessler's analysis collapses across two orthogonal dimensions of social value to explain contempt: relational value, predicted by cooperation, and agentic value, predicted by status. These dimensions interact to potentiate specific social emotions and behaviors in intergroup contexts. By neglecting the unique roles of these dimensions-and their associated attributes: warmth and competence-the sentiment framework cedes predictive precision.

Genetic studies on the prehispanic population buried in Punta Azul cave (El Hierro, Canary Islands)

The aim of this study was to establish the genetic studies of the population from one of the most important known aboriginal funerary spaces of the island of El Hierro (Canary Islands), the Punta Azul cave, which harbors remains of 127 individuals. Sixty-one adult tibiae were examined, 32 left and 29 right. Radiocarbon dating yields an antiquity of 1015–1210 AD. We have obtained an overall success rate of 88.5% for the molecular sexing, and of 90.16% for the uniparental markers. Short tandem repeats (STR) profiles were also possible for 45.9% of the samples. This performance is a consequence of the good conservation of the bones in their archaeological context. The mtDNA composition of the sample is characterized by the complete fixation of the H1-16260 lineage. These results can be explained by a mixture of consecutive founding events, a bottleneck episode at the beginning of the colonization and/or as a consequence of genetic drift. Paternal lineages were also affected by these processes but in a less acute way. These differences lead us to propose social behaviors as an explanation for this difference. The maternal transmission of the lineages, mentioned in ethnohistorical sources of the Archipelago, could be an explanation. These results could be in agreement with endogamous practices, but the autosomal STR results indicate a relative high diversity. These results have allowed us to characterize the Punta Azul cave population and see the way in which geographical isolation, the process of adaptation and specific social behaviors affected the aboriginal population of the Island.

Altered corticosterone levels and social play behavior after prolonged maternal separation in adolescent male but not female Wistar rats

Early-life socio-environmental factors are crucial for normal developmental processes; adverse experiences early in life can therefore lead to detrimental effects in several physiological systems. The aim of this study was to examine short-term effects of early adverse experiences in a maternal separation (MS) rodent model. In this study two separation conditions were used: daily 15- (MS15) or 360-min (MS360) separation of the litter from the dam during postnatal day 1–21. In early adolescence, male and female offspring were subjected to a single-isolation procedure with analysis of corticosterone levels prior to and after isolation. In addition, social play behavior was assessed during mid-adolescence. There was a clear difference between male and female offspring in both tests performed. There was no difference in corticosterone levels between the female MS groups, whereas MS360 males showed higher baseline and recovery corticosterone levels than MS15 males. The amount of pinning, a specific social play behavior, was affected by rearing with MS360 males having a higher frequency than MS15 males, while there was no difference between the female MS groups. The observation that males but not females are affected by MS360 has previously been reported for adult animals, and herein we show that this difference is present already in adolescence. Changes in corticosterone levels and social behavior following early-life adversity have been associated with adult behavioral alterations, and our results confirm that these changes emerge already within adolescence.

Economy and society of the Remi and Suessiones in Gallia Belgica during the last two centuries BC through the prism of archaeozoology

The Remi and the Suession territories, in northern France, are well known from an archaeological point of view thanks to the extensive excavation campaigns in the region of the Aisne Valley over the past 30 years. Focusing on the last two centuries BC – a crucial period for the Gallic peoples, right before the Roman invasion of Gallia Belgica – reveals evidence of extended urbanised sites, specialised production processes and complex social organisations. These results lead us to consider the Remi and the Suession populations not as barbarians as ancient textual sources tend to describe. Through the study of faunal remains accumulated on several archaeological sites of both territories, specific social behaviours linked to well-organised peoples emerge, for whom animal husbandry has become, over time, an important resource of production and trade, allowing them to develop economical and political alliance over borders. This study, adopting a territorial approach, examines the trading networks of animal resources for the Remi and Suession people to reach a better understanding of these complex societies. It also aims to expand our vision of Gallic communities by raising questions about animal husbandry in various regions of Gaul, such as Britain, the Netherlands and Switzerland.

A Cross-Cultural Examination of SNS Usage Intensity and Managing Interpersonal Relationships Online: The Role of Culture and the Autonomous-Related Self-Construal.

Perception of the autonomy and relatedness of the self may be influenced by one's experiences and social expectations within a particular cultural setting. The present research examined the role of culture and the Autonomous-Related self-construal in predicting for different aspects of Social Networking Sites (SNS) usage in three Asian countries, especially focusing on those aspects serving interpersonal goals. Participants in this cross-cultural study included 305 university students from Malaysia (n = 105), South Korea (n = 113), and China (n = 87). The study explored specific social and interpersonal behaviors on SNS, such as browsing the contacts' profiles, checking for updates, and improving contact with SNS contacts, as well as the intensity of SNS use, hypothesizing that those with high intensity of use in the Asian context may be doing so to achieve the social goal of maintaining contact and keeping updated with friends. Two scales measuring activities on other users' profiles and contact with friends' profiles were developed and validated. As predicted, some cross-cultural differences were found. Koreans were more likely to use SNS to increase contact but tended to spend less time browsing contacts' profiles than the Malaysians and Chinese. The intensity of SNS use differed between the countries as well, where Malaysians reported higher intensity than Koreans and Chinese. Consistent with study predictions, Koreans were found with the highest Autonomous-Related self-construal scores. The Autonomous-Related self-construal predicted SNS intensity. The findings suggest that cultural contexts, along with the way the self is construed in different cultures, may encourage different types of SNS usage. The authors discuss study implications and suggest future research directions.

Characterization of social behaviors in caspase-3 deficient mice.

Impaired social interaction is a defining feature of autism spectrum disorder, a neurodevelopmental disorder that shows a strong male preponderance in prevalence. Studies have identified neural circuits, neuromodulators and genetic factors involved in social behaviors, but mechanistic understanding of gender-specific social deficits is lacking. We report that deletion of the caspase-3 gene, encoding a protease with functions in apoptosis and neural plasticity, alters specific social behaviors in male mice, while leaving females unaffected. Casp3−/− mice showed normal behavioral responses to olfactory cues from food, neutral chemical and biological sources. Both Casp3−/− males and females displayed robust social exploration, sociability, recognition and preference for an enclosed novel mouse in the three-chamber test. However, Casp3−/− males showed significantly reduced social interaction behaviors when exposed to a freely moving novel mouse, including decreased interaction time and diminished mounting. Thus caspase-3 is essential for a subset of social behaviors, but despite similar hyper-locomotion in both sexes, only male Casp3−/− mice exhibited social interaction deficits, which is interesting given the male bias of autism.

Emotional arousal predicts observed social support in German and American couples talking about breast cancer.

Social support in couples often occurs during conversations and is an important predictor of positive outcomes in patients with breast cancer. Even though talking about cancer may be upsetting, vocally expressed emotional arousal and its association with social support have not been examined. The goal of this study was to examine the role of vocally encoded emotional arousal and social support behaviors in 129 German and American couples, assessed at baseline of clinical trials for women with breast cancer and their male partners. Range of fundamental frequency was used as a measure of expressed emotional arousal during videotaped interactions in which the women shared cancer-related concerns. Social support behaviors were assessed as specific social support behaviors at the talk-turn level (positive, neutral, and negative) and broader communication behaviors also relevant to social support at the global level (depth and articulation, caring, quality of communication) using the Social Support Interaction Coding System (Bradbury & Pasch, 1994). Data were analyzed using actor-partner interdependence models. Women displayed more positive, fewer neutral support-receiving behaviors, and greater depth and articulation if their own emotional arousal was higher. Women also displayed more neutral and (at the trend level) fewer positive support-receiving behaviors if their partners' emotional arousal was higher. Men's behaviors were not associated with their own or women's emotional arousal. Results indicate that it may be adaptive for women with cancer to openly experience their distress during social support conversations with their partners; high emotional arousal of the partners may interfere with this process.
