Saturation Experiment

Consistent individual differences in behavioural types may not only cause variation in life-history decisions, but may also affect the choice of social partners and sociality in general. Here, we tested whether and how behavioural type influences the establishment of social ties using the cooperatively breeding cichlid, Neolamprologus pulcher . In a habitat saturation experiment with individuals pre-tested for behavioural type, we first analysed whether behavioural type affected the likelihood of settlement (i.e. social status), group sizes, and the types of dominant and subordinate individuals accepted as group members. Corrected for effects of body size and sex, the behavioural type did not affect settlement. However, bold dominant males only accepted smaller females, and grouped with bold subordinates, while shy dominant males accepted larger females than themselves, and grouped with shy subordinates. Second, we analysed the relationships between behavioural type and the aggressiveness or affiliation social network. Behavioural type significantly affected the number and quality of connections within the two networks. We show that behavioural types affect group composition, social networks and status achieved, in interaction with body size. Thus, the interactions within groups may depend not only on age, size and sex, but also on the behavioural type of the individuals involved.

We depict Hollywood celebrity couples as business families who participate in the project-based movie production industry, which is a temporary and disaggregated form of organization where skilled individuals are linked to one another through contractual and social relationships. Appearing in Hollywood movies generates celebrity capital, which can be converted into economic capital through involvement in endorsements and other rent-generating activities. Finding projects is facilitated by membership in high-quality social networks, and we consider celebrity marriage as a means of merging two individuals’ social networks, which can be mutually beneficial for both parties. We develop and test three hypotheses about the quality of social networks prior to and after marriage and analyze their impact upon celebrities’ postmarriage career performance. We contribute to the family business literature by exploring hybridized and adaptive forms of business family in contemporary project industries, which has the potential to enlarge family business scholars’ research horizons.

Dopamine Receptor Genes

There is growing evidence that the number and quality of social relationships have substantial impacts on health, well-being, and longevity, and, at least in animals, on reproductive fitness. Although it is widely recognized that these outcomes are mediated by a number of neuropeptides, the roles these play remain debated. We suggest that an overemphasis on one neuropeptide (oxytocin), combined with a failure to distinguish between different social domains, has obscured the complexity involved. We use variation in 33 SNPs for the receptor genes for six well-known social neuropeptides in relation to three separate domains of sociality (social disposition, dyadic relationships, and social networks) to show that three neuropeptides (β-endorphin, oxytocin, and dopamine) play particularly important roles, with each being associated predominantly with a different social domain. However, endorphins and dopamine have a much wider compass than oxytocin (whose effects are confined to romantic/reproductive relationships and often do not survive control for other neuropeptides). In contrast, vasopressin, serotonin, and testosterone play only limited roles.

The Relationship

The purpose of this study was to investigate the relationship of childhood trauma to the quality of social networks and health outcomes later in adulthood. Data were obtained from a convenience sample of 254 adults seen in one of 10 primary care clinics in the state of Texas. Standardized measures of adverse childhood experiences (ACEs), stressful and supportive social relationships, medical conditions, anxiety, depression, and health-related quality of life were administered. Using latent class analysis, subjects were assigned to one of four ACE classes: (a) minimal childhood abuse (56%), (b) physical/verbal abuse of both child and mother with household alcohol abuse (13%), (c) verbal and physical abuse of child with household mental illness (12%), and (d) verbal abuse only (19%). Statistically significant differences across the four ACE classes were found for mental health outcomes in adulthood. Although respondents who were physically and verbally abused as children reported compromised mental health, this was particularly true for those who witnessed physical abuse of their mother. A similar relationship between ACE class and physical health was not found. The quality of adult social networks partly accounted for the relationship between ACE classes and mental health outcomes. Respondents exposed to ACEs with more supportive social networks as adults had diminished odds of reporting poor mental health. Conversely, increasing numbers of stressful social relationships contributed to adverse mental health outcomes. Although efforts to prevent childhood trauma remain a critical priority, the treatment of adult survivors needs to expand its focus on both strengthening social networks and decreasing the negative effects of stressful ones.

Practical Implications

Purpose – The purpose of this paper is to theoretically clarify the relationship between public service motivation and performance by suggesting a framework in which social networks among members provide an explicit mechanism linking employees’ PSM with their performance and by proposing several empirically testable propositions. Design/methodology/approach – The author suggests a theoretical framework based on a literature review and combining insights from several major strands of theory including social capital and social network theories. Findings – Conceptually, the paper shows that, first, the extent of the social relationships among group members and their positions within a network vary depending on the level of PSM; second, individuals with high PSM are more likely to complete their tasks when they are in central positions in a network of advice relations and less likely to complete their tasks when they are in peripheral positions in central positions and a network of advice relations in a network of adversarial relations; third, group members with high PSM are more likely to complete group tasks when the group has higher density in a network of advice relations and less likely to complete tasks in a dense network of adversarial relations. Practical implications – The author demonstrates the possibility of reciprocal relationships between PSM and social networks, in which PSM builds social capital that reinforces each member’s PSM by enhancing relationship quality, which will positively affect performance. Originality/value – This paper provides opportunities for future empirical research by developing the discussion about a new conceptual mechanism in the relationship between PSM and performance, proposing an initial conceptual framework that clarifies the PSM and performance linkage, and suggesting several testable propositions.

The study focuses on the communication effectiveness of SMM for small and medium-sized enterprises. The task of the article is to determine the effectiveness of advertising in social networks. The general set was production, trade enterprises, and service enterprises of the Udmurt Republic. The sample analyzed 180 advertising posts published in April and May 2019. For enterprises and advertising publications in the sample, a number of indicators of communication effectiveness were measured: the number of group members, the level of publication activity, coverage, the number of reactions, the quality of advertising posts, the level of community involvement. The analysis showed that over half of small and medium-sized companies practically do not use advertising in social networks. This applies to both INSTAGRAM accounts and VKontakte communities. At the same time, the average number of subscribers in communities is quite high for the market of the region in question. It was found that the quality of advertising publications is rather low on a number of key parameters, which include the level of novelty, emotional saturation, motivation to action, etc. The level of community involvement in INSTAGRAM was identified as low. At the same time, it is significantly higher than the one we calculated for the VKontakte social network. Based on this analysis, the article made a number of proposals for small and medium-sized businesses to more effectively use commercial accounts in social networks for advertising purposes.

Abstract In species with long-term social relationships, the ability to recognize individuals after extended separation and the ability to discriminate between former social affiliates that have died and those that have left the group but may return are likely to be beneficial. Few studies, however, have investigated whether animals can make these discriminations. We presented acorn woodpeckers (Melanerpes formicivorus), a group-living, cooperatively breeding bird, with playbacks of current group members, former group members still living nearby, former group members that had died or left the study area, and familiar nongroup members. Subjects responded more quickly to the calls of nongroup members than to the calls of current group members or former group members still living in the study area but did not discriminate between nongroup members and former group members that had died or disappeared. This suggests that acorn woodpeckers can vocally recognize both current group members and former group members that have dispersed to nearby groups and that they either forget former group members that no longer live in the vicinity or classify them differently from former group members that still live nearby. This study suggests an important role for vocal recognition in maintaining valuable relationships with social affiliates postdispersal.

Social Network Size

Previous studies showed that extraversion influences social network size. However, it is unclear how extraversion affects the size of different layers of the network, and how extraversion relates to the emotional intensity of social relationships. We examined the relationships between extraversion, network size, and emotional closeness for 117 individuals. The results demonstrated that extraverts had larger networks at every layer (support clique, sympathy group, outer layer). The results were robust and were not attributable to potential confounds such as sex, though they were modest in size (raw correlations between extraversion and size of network layer, .20 < r < .23). However, extraverts were not emotionally closer to individuals in their network, even after controlling for network size. These results highlight the importance of considering not just social network size in relation to personality, but also the quality of relationships with network members.

BACKGROUND With online health information becoming increasingly popular among patients and their family members, concerns have been raised about the accuracy from the websites. OBJECTIVE We aimed to evaluate the overall quality of the online information about scaphoid fracture obtained from Chinese websites using the local search engines. METHODS We conducted an online search using the keyword “scaphoid fracture” from the top 5 search engines in China, i.e. Baidu, Shenma, Haosou, Sougou and Bing, and gathered the top ranked websites, which included a total of 120 websites. Among them, 81 websites were kept for further analyses by removing duplicated and unrelated one as well as websites requiring payment. These websites were classified into four categories, including forum/social networks, commercials, academics and physician’s personals. Health information evaluation tool DISCERN and Scaphoid Fracture Specific Content Score (SFSCS) were used to assess the quality of the websites. RESULTS Among the 81 Chinese websites that we studied, commercial websites were the most common one accounting more than half of all websites. The mean DISCERN score of the 81 websites was 25.56 and no website had a score A (ranging from 64 to 80).The mean SFSCS score was 10.04 and no website had a score A (range between 24 and 30). In addition, DISCERN and SFSCS scores from academic and physician’s websites were significantly higher than those from the forum/social networks and commercials. CONCLUSIONS The overall quality of health information obtained from Chinese websites about scaphoid fracture was very low, suggesting that patients and their family members should be aware such deficiency and pay special attentions for the medical information obtained by using the current search engines in China.
