Gift-Giving and Network Structure in Rural China: Utilizing Long-Term Spontaneous Gift Records

The tradition of keeping written records of gift received during household ceremonies in many countries offers researchers an underutilized means of data collection for social network analysis. This paper first summarizes unique features of the gift record data that circumvent five prevailing sampling and measurement issues in the literature, and we discuss their advantages over existing studies at both the individual level and the dyadic link level using previous data sources. We then document our research project in rural China that implements a multiple wave census-type household survey and a long-term gift record collection. The pattern of gift-giving in major household social events and its recent escalation is analyzed. There are significantly positive correlations between gift network centrality and various forms of informal insurance. Finally, economic inequality and competitive marriage market are among the main demographic and socioeconomic determinants of the observed gift network structure.     

Obesity,Social Class,and Mental Illness

The relationship between obesity and mental health was investigated, using data obtained from 1,660 persons selected as representative of 110,000 inhabitants of a residential area of New York City. In addition to confirming the previously noted relationship between obesity and age, preliminary analysis revealed a striking relationship between obesity and socioeconomic status of origin. The prevalence of obesity was 7 times higher among women reared in the lowest social class category as compared with those reared in the highest category. Scores made by the obese respondents on 9 mental health indices were compared with scores made by individuals of average weight. The obese respondents made more pathological scores on 8 of the 9 measures and on 3 of these the difference was statistically significant (“immaturity,” “rigidity,” and “suspiciousness”).     

Myelodysplasia: Problems of Long-Term Survival and Social Function

Problems of ninety-eight patients with myelodysplasia, ages 13 to 72, were reviewed. They were grouped as follows: Those having thoracic and high lumbar level (L₂↑) lesions and confined to wheel chairs, those with intermediate paralysis (L_3-5 nerve roots) as walking with aids and those with less paralysis (S₁↓) as fully ambulatory. Fifty-two percent of the L₂↑ and only 15 percent of of the less severely paralyzed patients were retarded below an IQ level 70 (P<0.01). Thirty-six patients (62 percent) were fully and 26 partially, but appropriately, self-sufficient. Thirty-six patients were found in some form of dependent care. Two of the 71 more paralyzed patients (L_3-5 and L₂↑) and five of the 28 S₁↓ patients were “naturally continent” but reported stress incontinence of urine. Thirteen of 23 female and five of 28 male patients between ages 16 and 72 years reported sexual activity and accounted for 17 normal offspring. All 23 retarded patients were in some form of custodial care. Dependency among the normal intellect patients could be attributed to neglect of physically deforming complications and emotional disorders, primarily low self-esteem centering around social and sexual identity problems associated with excrement soiling.     

How Elephants are Opening Doors: Developmental Neuroethology, Attachment and Social Context

Ethology's renewed interest in developmental context coincides with recent insights from neurobiology and psychology on early attachment. Attachment and social learning are understood as fundamental mechanisms in development that shape core processes responsible for informing behaviour throughout a lifetime. Each field uniquely contributes to the creation of an integrated model and encourages dialogue between Tinbergen's four analytical levels: ethology in its underscoring of social systems of behaviour and context, psychology in its emphasis on socio‐affective attachment transactions, and neuroscience in its explication of the coupled development of brain and behaviour. We review the relationship between developmental context and behaviour outcome as a topic shared by the three disciplines, with a specific focus on underlying neuroethological mechanisms. This interdisciplinary convergence is illustrated through the example of abnormal behaviour in wild African elephants (Loxodonta africana) that has been systematically observed in human‐caused altered social contexts. Such disruptions impair normative socially mediated neuroendocrinological development leading to psychobiological dysregulation that expresses as non‐normative behaviour. Aberrant behaviour in wild elephants provides a critical field example of what has been established in ex situ and clinical studies but has been largely absent in wild populations: a concrete link between effects of human disturbance on social context, and short‐ and long‐term neuroethology. By so doing, it brings attention to the significant change in theories of behaviour that has been occurring across disciplines – namely, the merging of psychobiological and ethological perspectives into common, cross‐species, human inclusive models.     

Opening the Social Gateway: Early Vocal and Social Sensitivities in Brown-Headed Cowbirds (Molothrus ater)

The organization of cowbird ( Molothrus ater ) social groups affords individuals living in the groups different opportunities for learning and also structures trajectories of social development. Here, we studied the influence of adults on social organization of very young cowbirds. In three experiments, we housed juvenile birds in large, seminatural environments that either contained or did not contain adult conspecifics. We then observed the social associations and vocalizations of juveniles in each environment. The presence of adults in the social environment influenced the assortment and singing patterns of juveniles, although throughout the three experiments adults rarely interacted physically with juveniles. Juveniles housed with adults interacted with other juveniles more often and sang significantly less often than juveniles housed without adults. Effects of adult presence or absence on social organization and singing patterns emerged extremely rapidly and could be reversed quickly. Taken as a whole, the experiments revealed that very young cowbirds, in the first days of independence from their hosts, were sensitive to, and reacted rapidly to, the composition of their social environment. Specifically, presence of other age classes of individuals within the group increased juvenile associations and delayed production of vocalizations by juvenile males. Self-organization within the social group produced different social environments, which could in turn create different gateways for social learning and vocal development.

Impact of Mental Health Visits on Healthcare Cost in Patients with Diabetes and Comorbid Mental Health Disorders

Purpose

To assess the impact of mental health visits (MHV) on the cost of care for Veterans with diabetes and comorbid mental health conditions.

Methods

A national cohort of 120,852 Veterans with diabetes and at least one mental health diagnosis (i.e., substance abuse, depression or psychoses) in 2002 was followed through 2006. Outcomes were pharmacy, inpatient and outpatient costs in 2012 dollars.

Results

Least-square covariate adjusted estimates from the joint model of total VA costs of the number of MHV using December 31, 2012 value dollars indicate that relative to those with fewer MHV, those with 3+ MHV had the lowest mean inpatient cost ($21,406), but the highest mean outpatient and pharmacy cost ($9,727 and $2,015, respectively). If all Veterans who received zero MHV actually received 3+ MHV, we estimate through simulated scenarios that between $32,272,329 and $181,460,247 in inpatient costs would be saved. However, these savings would be offset by additional expenditures of between $1,166,017,547 and $1,166,224,787 in outpatient costs and between $151,604,683 and $161,439,632 in pharmacy costs.

Conclusions

Among Veterans with diabetes and comorbid mental disorders having three or more mental health visits is associated with marginally decreased inpatient cost, but these potential savings seem to be offset by increased outpatient and pharmacy costs.

Social Rhythm and Mental Health: A Cross-Cultural Comparison

Background

Social rhythm refers to the regularity with which one engages in social activities throughout the week, and has established links with bipolar disorder, as well as some links with depression and anxiety. The aim of the present study is to examine social rhythm and its relationship to various aspects of health, including physical health, negative mental health, and positive mental health.

Method

Questionnaire data were obtained from a large-scale multi-national sample of 8095 representative participants from the U.S., Russia, and Germany.

Results

Results indicated that social rhythm irregularity is related to increased reporting of health problems, depression, anxiety, and stress. In contrast, greater regularity is related to better overall health state, life satisfaction, and positive mental health. The effects are generally small in size, but hold even when controlling for gender, marital status, education, income, country, and social support. Further, social rhythm means differ across Russia, the U.S., and Germany. Relationships with mental health are present in all three countries, but differ in magnitude.

Conclusions

Social rhythm irregularity is related to mental health in Russia, the U.S., and Germany.     

Long-Term Evolution of Email Networks: Statistical Regularities,Predictability and Stability of Social Behaviors

In social networks, individuals constantly drop ties and replace them by new ones in a highly unpredictable fashion. This highly dynamical nature of social ties has important implications for processes such as the spread of information or of epidemics. Several studies have demonstrated the influence of a number of factors on the intricate microscopic process of tie replacement, but the macroscopic long-term effects of such changes remain largely unexplored. Here we investigate whether, despite the inherent randomness at the microscopic level, there are macroscopic statistical regularities in the long-term evolution of social networks. In particular, we analyze the email network of a large organization with over 1,000 individuals throughout four consecutive years. We find that, although the evolution of individual ties is highly unpredictable, the macro-evolution of social communication networks follows well-defined statistical patterns, characterized by exponentially decaying log-variations of the weight of social ties and of individuals’ social strength. At the same time, we find that individuals have social signatures and communication strategies that are remarkably stable over the scale of several years.

Contesting the Politics of Culture, Rewriting the Boundaries of Inclusion: Working for Social Justice with Muslim and Arab Communities

This article calls on anthropologists of education to assert a more public voice attacking the ideological purposes to which the concept of "culture" has been deployed following the September 11 attacks. We must support schools, communities, and the media to address the power and politics of race and religion in contemporary social and political contexts, rather than focus primarily on multicultural education about Islamic and Arab "culture." Finally, this article urges us to expand our knowledge of the processes of social incorporation for Muslim and Arab immigrant youth to include a deeper understanding of how global politics contribute to young people's sense of emerging identities.     

Cognitive Performance and Long-Term Social Functioning in Psychotic Disorder: A Three-Year Follow-Up Study

ObjectiveStudies have linked cognitive functioning to everyday social functioning in psychotic disorders, but the nature of the relationships between cognition, social cognition, symptoms, and social functioning remains unestablished. Modelling the contributions of non-social and social cognitive ability in the prediction of social functioning may help in more clearly defining therapeutic targets to improve functioning.MethodIn a sample of 745 patients with a non-affective psychotic disorder, the associations between cognition and social cognition at baseline on the one hand, and self-reported social functioning three years later on the other, were analysed. First, case-control comparisons were conducted; associations were subsequently further explored in patients, investigating the potential mediating role of symptoms. Analyses were repeated in a subsample of 233 patients with recent-onset psychosis.ResultsInformation processing speed and immediate verbal memory were stronger associated with social functioning in patients than in healthy controls. Most cognition variables significantly predicted social functioning at follow-up, whereas social cognition was not associated with social functioning. Symptoms were robustly associated with follow-up social functioning, with negative symptoms fully mediating most associations between cognition and follow-up social functioning. Illness duration did not moderate the strength of the association between cognitive functioning and follow-up social functioning. No associations were found between (social) cognition and follow-up social functioning in patients with recent-onset psychosis.ConclusionsAlthough cognitive functioning is associated with later social functioning in psychotic disorder, its role in explaining social functioning outcome above negative symptoms appears only modest. In recent-onset psychosis, cognition may have a negligible role in predicting later social functioning. Moreover, social cognition tasks may not predict self-reported social functioning.
