Status competition,inequality, and fertility: implications for the demographic transition

The role that social status plays in small-scale societies suggests that status may be important for understanding the evolution of human fertility decisions, and for understanding how such decisions play out in modern contexts. This paper explores whether modelling competition for status—in the sense of relative rank within a society—can help shed light on fertility decline and the demographic transition. We develop a model of how levels of inequality and status competition affect optimal investment by parents in the embodied capital (health, strength, and skills) and social status of offspring, focusing on feedbacks between individual decisions and socio-ecological conditions. We find that conditions similar to those in demographic transition societies yield increased investment in both embodied capital and social status, generating substantial decreases in fertility, particularly under conditions of high inequality and intense status competition. We suggest that a complete explanation for both fertility variation in small-scale societies and modern fertility decline will take into account the effects of status competition and inequality.     

Bringing the margins into the middle: reflections on racism,class and the racialized outsider

This paper explores Virdee’s account of how racialized minorities in socialist movements ‘played an instrumental role in trying to align struggles against racism with those against class exploitation’ (p. 164). In so doing, Virdee makes an important intervention at a time when popular historians and other ideologues are colluding in the elevation of myths and – no doubt in their view – noble lies that preclude these stories. Moving through theoretical debates concerning the relationships between race and class, the nature and form of sociologies of ‘outsiders’, to political issues of mobilization, Virdee’s book successfully brings in from the margins an account the multi-ethnic character of the working class in England from the very moment of its inception.     

Migration,ethnicity and psychoses: evidence,models and future directions

There is a large body of research reporting high rates of psychotic disorders among many migrant and minority ethnic groups, particularly in Northern Europe. In the context of increasing migration and consequent cultural diversity in many places worldwide, these findings are a major social and public health concern. In this paper, we take stock of the current state of the art, reviewing evidence on variations in rates of psychoses and putative explanations, including relevant theories and models. We discuss in particular: a) the wide variation in reported rates of psychotic disorders by ethnic group, and b) the evidence implicating social risks to explain this variation, at ecological and individual levels. We go on to set out our proposed socio‐developmental model, that posits greater exposure to systemic social risks over the life course, particularly those involving threat, hostility and violence, to explain high rates of psychoses in some migrant and minority ethnic groups. Based on this analysis, the challenge of addressing this social and public health issue needs to be met at multiple levels, including social policy, community initiatives, and mental health service reform.     

Cloning,Sequencing, and Expression of the Gene Encoding 4-Hydroxy-4-methyl-2-oxoglutarate Aldolase from Pseudomonas ochraceae NGJ1

A DNA fragment that carried the gene (proA) encoding 4-hydroxy-4-methyl-2-oxoglutarate aldolase was cloned from the chromosomal DNA of Pseudomonas ochraceae NGJ1, and the coding region was assigned to the nucleotide sequence based on the N-terminal amino acid sequence of the enzyme purified from the organism. The proA gene was 684 bp long, corresponding to a protein of 227 amino acid residues with a calculated molecular mass of 24,067 Da. The genes encoding a putative transporter and a 4-oxalomesaconate hydratase were upstream, and a 3'-truncated gene encoding 2-pyrone-4,6-dicarboxylate lactonase was downstream from the proA gene in the same orientation on the DNA fragment. The proA gene product was overproduced in Escherichia coli and briefly purified to homogeneity from the crude extract by a two-step purification. The molecular and catalytic properties of the gene product were similar to those of the P. ochraceae enzyme.     

Definitions of national identity,nationalism and ethnicity in post-Soviet Azerbaijan in the 1990s

This article examines the major political debates in post-Soviet Azerbaijan vis à vis the very assumptions of individual autonomy, equality, national culture and citizenship, and universalism upon which modern nation-states have historically been based. The information presented in this article is based on personal interviews conducted with the leading and influential members of the Azerbaijani political elite in 1998. The interviews were based on two broad themes. The first relates to the perceptions of the Soviet period and on what grounds the Azerbaijanis differentiate the new Republic of Azerbaijan from the former Soviet Azerbaijan. The second relates to their perceptions of both the outside world and themselves with regards to differing understandings of nationalism, national culture, and national/ethnic or local identities. The study of the Azerbaijani example of post-Soviet political culture may help us to understand the dynamics of nation-building on the basis of the major political debates and of conflicting national, ethnic and local identities in Azerbaijan.     

On getting nothing back: Managing the meaning of ethnicity in Canada's northwest territories*

In analysing life‐cycle rituals (rites of passage) it is important to consider not only the relationship between individuals and society, but also the role of the household. The change in status that an individual achieves through life‐cycle rituals also has implications for the status of the members of his/her household and of other kin. In the Andes, life‐cycle rituals are necessary for the physical, social and spiritual development of individuals and households. Analyses that exclusively associate physical development with ‘natural’ parents and social and spiritual development with godparents, ignore the complex relationship between the households of parents, children and godparents.     

Income inequality and depression: a systematic review and meta‐analysis of the association and a scoping review of mechanisms

Most countries have witnessed a dramatic increase of income inequality in the past three decades. This paper addresses the question of whether income inequality is associated with the population prevalence of depression and, if so, the potential mechanisms and pathways which may explain this association. Our systematic review included 26 studies, mostly from high‐income countries. Nearly two‐thirds of all studies and five out of six longitudinal studies reported a statistically significant positive relationship between income inequality and risk of depression; only one study reported a statistically significant negative relationship. Twelve studies were included in a meta‐analysis with dichotomized inequality groupings. The pooled risk ratio was 1.19 (95% CI: 1.07‐1.31), demonstrating greater risk of depression in populations with higher income inequality relative to populations with lower inequality. Multiple studies reported subgroup effects, including greater impacts of income inequality among women and low‐income populations. We propose an ecological framework, with mechanisms operating at the national level (the neo‐material hypothesis), neighbourhood level (the social capital and the social comparison hypotheses) and individual level (psychological stress and social defeat hypotheses) to explain this association. We conclude that policy makers should actively promote actions to reduce income inequality, such as progressive taxation policies and a basic universal income. Mental health professionals should champion such policies, as well as promote the delivery of interventions which target the pathways and proximal determinants, such as building life skills in adolescents and provision of psychological therapies and packages of care with demonstrated effectiveness for settings of poverty and high income inequality.     

Kinship on the Kibbutz: coresidence duration predicts altruism, personal sexual aversions and moral attitudes among communally reared peers

The natural experiments created by the Israeli Kibbutzim and Taiwanese minor marriages provide unique testing grounds for investigating the mechanisms governing sibling detection, inbreeding avoidance and kin-selected altruism. Here we present two studies conducted on the coreared peers of Israeli Kibbutzim. We examined how coresidence duration — a cue that would have indicated genetic relatedness in ancestral environments — impacts the development of kin-directed behaviors. In both studies, we found that coresidence duration predicts levels of altruism and sexual aversions directed toward peers. We also investigated the relationship between personal sexual aversions and moral attitudes relating to peer sexual behavior. The absence of norms proscribing sex between peers on the Kibbutz allows for a more tightly controlled investigation of this relationship. We found that total coresidence duration with opposite-sex peers predicts the intensity of moral wrongness associated with third-party peer sexual behavior, but not other behaviors, including sibling incest. More directly, we found that the summed sexual aversion felt toward all opposite-sex peers predicts levels of moral wrongness associated with third-party peer sex. Mediation analyses confirmed that personal sexual aversions mediate the relationship between coresidence duration and moral attitudes regarding peer sex. These results bolster Westermarck's original claims that childhood coresidence serves as a kinship cue, leading to greater sexual aversions and altruistic motivations, and that personal sexual aversions shape attitudes relating to third-party sexual behavior.     

Conceiving Reproduction: New Reproductive Technologies and the Redefinition of the Kinship Narrative in New Zealand Society

This paper focuses on technologies for assisting conception and considers how normative notions of conception and family formation have informed the rejection, incorporation and adaptation of technologies and their regulation in New Zealand. Drawing on a textual analysis of primary written materials and secondary sources generated between 1965 and 2004, the paper reveals how these technologies help various groups in New Zealand society make explicit their understandings of relatedness, identity and social and cultural belonging. Whilst biological/genetic connection and social connections inform understandings of kinship, reproduction, parenthood and social structure for many New Zealanders, the boundaries between the biological and social are often blurred and precedence of one over the other is very much context dependent. The incorporation of the new reproductive technologies has been an inherently politicised process, with barriers to access to these technologies emerging in relation to ethnic identity and race, sexuality, socioeconomic status, gender, and marital status.     

Of lemmings and snowshoe hares: the ecology of northern Canada

Two population oscillations dominate terrestrial community dynamics in northern Canada. In the boreal forest, the snowshoe hare (Lepus americanus) fluctuates in cycles with an 8-10 year periodicity and in tundra regions lemmings typically fluctuate in cycles with a 3-4 year periodicity. I review 60 years of research that has uncovered many of the causes of these population cycles, outline areas of controversy that remain and suggest key questions to address. Lemmings are keystone herbivores in tundra ecosystems because they are a key food resource for many avian and mammalian predators and are a major consumer of plant production. There remains much controversy over the role of predation, food shortage and social interactions in causing lemming cycles. Predation is well documented as a significant mortality factor limiting numbers. Food shortage is less likely to be a major limiting factor on population growth in lemmings. Social interactions might play a critical role in reducing the rate of population growth as lemming density rises. Snowshoe hares across the boreal forest are a key food for many predators and their cycles have been the subject of large-scale field experiments that have pinpointed predation as the key limiting factor causing these fluctuations. Predators kill hares directly and indirectly stress them by unsuccessful pursuits. Stress reduces the reproductive rate of female hares and is transmitted to their offspring who also suffer reduced reproductive rates. The maternal effects produced by predation risk induce a time lag in the response of hare reproductive rate to density, aiding the cyclic dynamics.     

Knives and Sheaths: Notes on a sexual idiom of social inequality in North Yemen*

The following article, based on field work in a mestizo parish in Highland Ecuador, examines how women (and some men) describe and interpret marital violence. Their interpretations are analyzed with reference to the socio‐economic conditions of the area of study, and with reference to the dominant gender ideology in mestizo societies, characterized by machismo/marianismo. It is argued that discrepancies between an ideology of male dominance and a much more equalitarian practice, together with an ambiguous notion of masculinity as both powerful and extremely fragile, dependent on female sexual conduct, create an “insecurity of maleness” which under certain circumstances is dealt with in violent terms.     

Relative index of inequality: definition, estimation, and inference

The relative index of inequality (RII) is a commonly used measure of the extent to which the occurrence of an outcome such as chronic illness or early death varies with socioeconomic status or some other background variable. The standard RII estimator applies only to linear variation in incidence rates. In this paper a general definition of the RII is introduced, alternative approaches to point estimation are considered, and a parametric bootstrap method is suggested for the construction of approximate confidence intervals. Estimation based on cubic splines fitted by maximum penalized likelihood is developed in some detail, and the proposed approach handles naturally the commonly needed adjustment for a 'standardizing' covariate such as age. Death rates in a large longitudinal study in England and Wales from 1996-2000 are analyzed in order to illustrate the various methods. A small simulation study explores the relative merits of different estimators. The approach based on cubic splines is found to reduce bias substantially, at the expense of some increase in variance, when variation in incidence rates is nonlinear.     

Frequency of discussing HIV prevention and care topics with patients with HIV: Influence of physician gender,race/ethnicity,and practice characteristics

Background: Because people living with HIV now have greater life expectancy and reduced morbidity, there is a greater need for physicians to discuss HIV transmission risk reduction with these patients. Very limited data are available examining how frequently this discussion is held.Objective: We examined the frequency of discussing HIV prevention and HIV care topics, as well as the associations of gender, race/ethnicity, and practice characteristics of physicians caring for persons with HIV.Methods: In a 4-city (Miami, Atlanta, Baltimore, Los Angeles) survey, 417 licensed physicians who primarily cared for patients with HIV were mailed a 58-item questionnaire about how frequently they discussed HIV transmission risk reduction, adherence to HIV antiretroviral treatment (ART), adherence to opportunistic infection (OI) prophylaxis, and how to take medicines. Multivariate logistic regression analyses were used to examine the association between physician gender, race/ethnicity, and practice characteristics, and the frequency of discussing these topics.Results: A total of 317 physicians responded to the mailed questionnaire. Less than 40% of the physicians reported always discussing HIV transmission risk reduction with patients. In contrast, 83.9% and 65.0% reported always discussing adherence to ART and to OI prophylaxis, respectively. Of these physicians, 65.1% strongly agreed or somewhat agreed that they had sufficient time to provide the care and information needed to their patients. In multivariate analysis, the frequency of discussing HIV transmission risk reduction was higher for physicians who were Hispanic (P = 0.03) or Asian/Pacific Islander (P = 0.001), for physicians who reported they had enough time to provide care and information to patients (P = 0.003), and for physicians who cared for fewer patients (P = 0.05). The frequency of discussing HIV transmission risk reduction was suggestive of a higher rate for female physicians, but did not quite reach statistical significance.Conclusions: We observed a lower frequency of discussing the topic of HIV prevention compared with that of HIV care among the physicians surveyed. This infrequent discussion with patients with HIV represents a missed opportunity, and physicians should be encouraged to include discussion of prevention as a standard of care.     

Genetic demographic structure of the Belgorod population: age, ethnicity, education, and occupation

Data from marriage records of the city of Belgorod for 1960, 1985, and 1995 have been used to determine some parameters of population structure in this city. The coefficients of correlation with respect to age of marriage between spouses in the couples contracting marriages in these years were 0.74, 0.62, and 0.80, respectively. Women of reproductively unfavorable age (under 20 or over 30 years) accounted for 5.5, 0.83, and 19% of all women contracting marriages in these years, respectively. The proportions of interethnic marriages in these years were 16.9, 14.9, and 15.6%, respectively. The percentage of Slavs decreased from 99 to 97% during the 35 years studied, whereas the proportion of Russians insignificantly increased (from 90.4 to 91.4%). The proportion of Caucasian ethnic groups increased by six time (from 0.3 to 1.8%), and that of other non-Slavic ethnic groups increased by almost two times (from 0.7 to 1.2%). The marriage convergence (K) with respect to ethnicity (0.095, 0.106, and 0.090 in 1960, 1985, and 1995, respectively) was lower than that with respect to education (0.296 and 0.350 in 1985 and 1995, respectively) or occupation (0.212 and 0.231 in 1985 and 1995, respectively). The maximum coefficients of ethnically, educationally, and occupationally assortative marriage have been found, respectively, in ethnic minority groups (A' = 20%); in persons with higher and primary education (A' = 37.5 and A' = 49.9%, respectively); and in the military officers/soldiers, engineers, healthcare professionals, and researchers (the respective A' values are 65.6, 32.2, 31.5, and 39.8%).     

Like one of the family: race,ethnicity, and the paradox of US national identity

The tensions between individual rights promised to US citizens and group discrimination targeted against African Americans and similar racial/ethnic groups constitute one enduring paradox of US society. This essay examines this paradox by exploring how a gendered family rhetoric contributes to understandings of race and US national identity. Using African American women's experiences as a touchstone for analysis, the article suggests that African American women's treatment as second-class citizens reflects a belief that they are 'like one of the family', that is, legally part of the US nation-state, but simultaneously subordinated within it. To investigate these relationships, the article examines 1) how intersecting social hierarchies of race and ethnicity foster racialized understandings of US national identity; 2) how the gendered rhetoric of the American family ideal naturalizes and normalizes social hierarchies; and 3) how gendered family rhetoric fosters racialized constructions of US national identity as a large national family.
