Consanguinity in Spain: socioeconomic,demographic, and geographic influences

Information on consanguinity in Spain was reanalyzed in order to obtain a more complete picture of consanguinity patterns by considering temporal, geographical, demographic, and economic factors. To obtain data on consanguineous marriages, we reviewed 106 published references. Only populations with homogeneous geographical characteristics, economic activities, transportation facilities, and the like, were considered. Two-way analysis of variance (ANOVA) provided highly significant differences (p < 0.001) for a both for time periods and for urban versus rural patterns, but there was no interaction between the latter two. A regression analysis shows that for rural areas the geographic characteristics, economy, communications, and index of demographic tendency were significant predictors of the inbreeding coefficient. The results obtained indicate that urban and rural patterns differ significantly and that the temporal factor needs to be taken into account before comparing inbreeding coefficients. In urban areas the census size and altitude are included in the regression equation as significant variables, but association was not found between alpha and the index of demographic tendency (population increase or decrease). Instead, the absolute number of inhabitants (census size) was significant. In rural areas geographic characteristics, communications, and index of demographic tendency were significant predictors of the inbreeding coefficient.     

Introduction to the special section: "the effects of bonds between human and nonhuman primates on primatological research and practice"

This commentary introduces this special section on ‘‘the Effects of Bonds Between Human and Nonhuman Primates on Primatological Research and Practice.’’ The aim is to explore the different causes and consequences of bonding experiences between observers and observed in different primatological contexts. In the first contribution, Vitale asks what are the possible consequences of such bonding in behavioral primatology. Examples of beneficial consequences of this kind of relationship come fromstudies on cognitive abilities of great apes. Furthermore, an empathic attitude with the experimental animals leads to better care and attention toward individual welfare needs. Coleman discusses the particular case of nonhuman primates housed in research laboratories. Care-giving practices arediscussed in relation to scientific, ethical and emotional issues. Morimura et al. present the case of the first Japanese sanctuary for retiring chimpanzees from research where, in order to facilitate the social living of re-located chimpanzees, face-to-face interactions between caregivers and chimpanzees areessential. Asquith discusses the role of an thropomorphism, and proposes that this attitude can help to better understand the lives of primates, in more contextualized scenarios. In relation to this view, sheemphasizes how the term ‘‘primate culture’’ accords with some definition of the term ‘‘human culture.’’Fuentes, in his article asks whether national, class and ethnic characteristics can influence bonding between human and nonhuman primates, and calls for focused quantitative studies. Finally, Rose calls for the application of the concept of biosynergy, explained as promoting the formation of healthy and sustainable bonding relationships among living creatures. One of the most important aspects emerging from these papers is the need to better understand whether the issue of bonding in primatological studiescan be generalized to other areas of research such as conservation, behavior, captive care, or whether each of these disciplines needs to develop their own understanding of the effects of bonding in ‘‘producing science.’’     

Being harmed while doing good: affective injuries in a community development programme,Medan, Indonesia

Complaints, accusations, and failures of gratitude are everyday experiences for volunteers in community‐driven development in Medan, Indonesia. In this article I develop the analytic of ‘affective injury’ to describe the force of such encounters: the sensation of having one's ethical self questioned or put at risk that manifests as an immediate force or lingering hurt. While humanitarian and development workers are all susceptible to affective injuries, I argue that they operate on a different register for developers who belong to, and have an enduring relationship with, the ‘community’. The ways local volunteers respond to, and seek to recover from, affective injuries are distinct from reflective responses to ethical dilemmas. The suppression of, or diversion from, thoughts that could derail self‐understanding is a hindrance to reflexive development practice.     

Household and community socioeconomic influences on early childhood malnutrition in Africa

This paper uses multilevel modelling and Demographic and Health Survey data from five African countries to investigate the relative contributions of compositional and contextual effects of socioeconomic status and place of residence in perpetuating differences in the prevalence of malnutrition among children in Africa. It finds that community clustering of childhood malnutrition is accounted for by contextual effects over and above likely compositional effects, that urban-rural differentials are mainly explained by the socioeconomic status of communities and households, that childhood malnutrition occurs more frequently among children from poorer households and/or poorer communities and that living in deprived communities has an independent effect in some instances. This study also reveals that socioeconomic inequalities in childhood malnutrition are more pronounced in urban centres than in rural areas.     

Adult socioeconomic,educational, social,and psychological outcomes of childhood obesity: a national birth cohort study

Objectives To assess adult socioeconomic, educational, social, and psychological outcomes of childhood obesity by using nationally representative data.Design 1970 British birth cohort.Participants 16 567 babies born in Great Britain 5-11 April 1970 and followed up at 5, 10, and 29-30 years.Main outcome measures Obesity at age 10 and 30 years. Self reported socioeconomic, educational, psychological, and social outcomes at 30 years. Odds ratios were calculated for the risk of each adult outcome associated with obesity in childhood only, obesity in adulthood only, and persistent child and adult obesity, compared with those obese at neither period.Results Of the 8490 participants with data on body mass index at 10 and 30 years, 4.3% were obese at 10 years and 16.3% at 30 years. Obesity in childhood only was not associated with adult social class, income, years of schooling, educational attainment, relationships, or psychological morbidity in either sex after adjustment for confounding factors. Persistent obesity was not associated with any adverse adult outcomes in men, though it was associated among women with a higher risk of never having been gainfully employed (odds ratio 1.9, 95% confidence interval 1.1 to 3.3) and not having a current partner (2.0, 1.3 to 3.3).Conclusions Obesity limited to childhood has little impact on adult outcomes. Persistent obesity in women is associated with poorer employment and relationship outcomes. Efforts to reduce the socioeconomic and psychosocial burden of obesity in adult life should focus on prevention of the persistence of obesity from childhood into adulthood.     

Experience of violence and socioeconomic position in South Africa: a national study

Background

Violence is a leading cause of morbidity and mortality in South Africa and needs to be researched from a public health perspective. Typically in violence research, socioeconomic position is used in the analysis to control for confounding. Social epidemiology approaches this variable as a primary determinant of interest and is used in this research to better understand the aetiology of violence in South Africa. We hypothesised that measures of socioeconomic position (employment, education and household wealth) would be inversely related to violence at the individual and household levels.

Methodology/Principal Findings

Data came from the1998 South African Demographic and Health Survey (SADHS). Measures of socioeconomic position used were employment, education and household wealth. Eighty-eight people (0.2%) received treatment for a violent injury in the previous 30 days and 103 households (0.9%) experienced a violent death in the previous year. Risk factors for violence at the individual level included employment (41% of those who experienced violence were employed vs. 27% of those who did not, p = 0.02), and education (those who experienced violence had on average, one year more education than those who did not, p = 0.04). Belonging to a household in the wealthiest quintile was protective against violence (OR: 0.32; 95% CI: 0.12–0.89). In contrast, at the household level all three measures of socioeconomic position were protective against the experience of a violent death. The only association to persist in the multivariate analysis was that between the wealth of the household and violence at the individual level.

Conclusions/Significance

Our hypothesis was supported if household wealth was used as the measure of socioeconomic position at the individual level. While more research is needed to inform the conflicting results observed between the individual and household levels, this analysis has begun to identify the disparities across the socioeconomic structure with respect to violent outcomes.     

New ethnic and national questions in Scotland: post-British identities among Glasgow Pakistani teenagers

The problematic relationship between 'Britishness' and the identities of UK ethnic minorities is further complicated in Scotland by the increasing salience of the Scottish dimension. This article discusses the relationship between reformulations of 'post-British' national identities, and the position of Scottish Pakistani-Muslims. The study focuses on the preferred identities of young Pakistani-Scots in West Central Scotland, reporting chiefly on the results of the modified Twenty Statement Test [TST] as administered to sixty-three Scottish-Pakistani teenagers aged between fourteen and seventeen years, estimated as a significant percentage of the Glasgow Pakistani population in this age range. Religious, ethnic and nationality labels are all adopted by these respondents. Where there are no constraints on their identity labels, religious (Muslim) statements predominate, and where a choice of labels is provided, dual ethnicity labels are preferred. The results are theorized in relation to present deficiencies in the acceptance of plural or 'hyphenate' identities within the United Kingdom.     

Extant primates and development of primatology in China: Publications,student training,and funding

China supports the richest non-human primate diversity in the northern hemisphere, providing an excellent opportunity for Chinese primatologists to take a leading role in advancing the study of primatology.Primatology in China began to flourish after 1979. To date, Chinese primatologists have published more than 1 000 papers in journals indexed by the Chinese Science Citation Database and the Web of Science Core Collection, and universities and academic institutions have trained 107 PhD students and 370 Masters students between 1984 and 2016. In total,the National Science Foundation of China has funded129 primate projects(RMB 71.7 million) supporting 59 researchers from 28 organizations. However, previous research has also shown obvious species bias.Rhinopithecus roxellana, Rhinopithecus bieti, and Macaca mulatta have received much greater research attention than other species. Researchers have also tended to continue to study the same species(55.2%)they studied during their Ph D training. To promote the development of primatology in China, we suggest(1)the need for a comprehensive primatology textbook written in Chinese,(2) continued training of more Ph D students, and(3) encouragement to study less well-known primate species.     

Global alteration of freshwaters: influences on human and environmental well-being

Human and environmental well-being—including disease resistance or avoidance, good nutrition, and species-appropriate population dynamics—are congruent with sustained healthy conditions. Unfortunately, hydrological alterations designed to benefit human societies often have unintended—and sometimes severe—consequences for the environment and the biodiversity it supports, and hence affecting billions of people. Improving this situation necessitates new water-resource developments, better water-use efficiency, and a reduction of contamination. Overall, the influences of existing and future freshwater (FW) regimes on human and environmental well-being are varied and wide-ranging. Furthermore, the scale is daunting: >1 billion people currently live in basins likely to require river management interventions for climate change alone. Global declines in FW biodiversity, in the nutritional value, and abundance of harvestable FW and riparian products, as well as deterioration in habitat quality for many species, require solutions; as do ongoing increases in the spread of FW-related diseases and non-native species. Modifications to FWs are now manifested in population declines and non-sustainable demographics for many aquatic species, as well as in deterioration of human health. In response, scientists, policy-makers, and water users are beginning to conceptualize FWs in terms of a global water system (GWS) to better understand and manage anthropogenic impacts. This involves identifying the ecological and policy implications of changes to the GWS, establishing international programs to understand and resolve major social and environmental issues arising from those changes, and developing broad-based mitigation or restoration techniques (e.g., environmental flow methodologies). Achieving these goals is paramount for maintaining human health as well as for the FW ecosystems upon which we depend.     

Cultural and health influences on building,housing, and community standards: Cost implications for the human habitat

International research and practices are reviewed with regard to cultural, social, economic, health, and physical-technological features of needs, standards, and codes regulating the residential environment. Housing and building codes, as well as zoning and subdivision ordinances, are influenced by nonscientific considerations that have significant cost and other policy implications. Noxious and promotive influences are examined for public health codes regulating potable water, waste disposal, and safety in the home, as well as density and congestion for cities, neighborhoods, and individual dwelling units. Density is distinguished from congestion, and the policy implications of both are examined. Cost-benefit ratios indicate that many standards can be appreciably lowered. Vague definitions of health, as adopted by WHO, also invite costinducing moral judgments.     

Genetic and environmental influences on human birth weight

Path-analytic techniques were used to demonstrate a significant influence of both fetal genes and maternal environment on birth weight in a sample of infants born to primarily white, middle-class, nonsmoking mothers. If the mother smoked before conception, however, the expression of the fetal birth-weight genes in males was significantly reduced. Multiparity was associated with an increase in genetic variance. This is the first report that genetic influences on birth weight are dependent on the environmental conditions imposed on the fetus by the mother.     

Genetic and environmental influences on human psychological differences

Psychological researchers typically distinguish five major domains of individual differences in human behavior: cognitive abilities, personality, social attitudes, psychological interests, and psychopathology (Lubinski, 2000). In this article we: discuss a number of methodological errors commonly found in research on human individual differences; introduce a broad framework for interpreting findings from contemporary behavioral genetic studies; briefly outline the basic quantitative methods used in human behavioral genetic research; review the major criticisms of behavior genetic designs, with particular emphasis on the twin and adoption methods; describe the major or dominant theoretical scheme in each domain; and review behavioral genetic findings in all five domains. We conclude that there is now strong evidence that virtually all individual psychological differences, when reliably measured, are moderately to substantially heritable.     

The use of racial, ethnic, and ancestral categories in human genetics research

The global dispersal of anatomically modern humans over the past 100,000 years has produced patterns of phenotypic variation that have exerted—and continue to exert—powerful influences on the lives of individuals and the experiences of groups. The recency of our common ancestry and continued gene flow among populations have resulted in less genetic differentiation among geographically distributed human populations than is observed in many other mammalian species. Nevertheless, differences in appearance have contributed to the development of ideas about “race” and “ethnicity” that often include the belief that significant inherited differences distinguish humans. The use of racial, ethnic, and ancestral categories in genetics research can imply that group differences arise directly through differing allele frequencies, with little influence from socially mediated mechanisms. At the same time, careful investigations of the biological, environmental, social, and psychological attributes associated with these categories will be an essential component of cross-disciplinary research into the origins, prevention, and treatment of common diseases, including those diseases that differ in prevalence among groups.     

Taenia tapeworms: their biology,evolution and socioeconomic significance

A biological context for understanding human pathogens and parasites emanates from evolutionary studies among tapeworms of the genus Taenia. Human taeniasis and cysticercosis represent archaic associations and remain significant challenges for socioeconomic development, public health and food safety, and a continuing threat to animal production on a global basis.
