„Solidarität“ in südasiatischen Gesellschaften

Taking South Asia as an example, it is shown how efforts to designate “solidarity” as a universally valid category are handicapped on the one hand by the ambiguity of the concept, on the other by its culture-specificity. Based on a linguistic, historical and social overview, it is demonstrated that the discourse parameters for “solidarity” as they dominate in the German language discourse are little suited for the South Asian reality. This leads to critical deliberations on the assumption that concepts and notions of the so-called West are to be seen as universally valid and universally binding.     

Some variations on constrained minimum enclosing circle problem

Given a set P of n points and a straight line L, we study three important variations of minimum enclosing circle problem as follows:

1. Computing k identical circles of minimum radius with centers on L, whose union covers all the points in P.
2. Computing the minimum radius circle centered on L that can enclose at least k points of P.
3. If each point in P is associated with one of the k given colors, then compute a minimum radius circle with center on L such that at least one point of each color lies inside it.

We propose three algorithms for Problem (i). The first one runs in O(nklogn) time and O(n) space. The second one is efficient where k?n; it runs in O(nlogn+nk+k ²log³ n) time and O(nlogn) space. The third one is based on parametric search and it runs in O(nlogn+klog⁴ n) time. For Problem (ii), the time and space complexities of the proposed algorithm are O(nk) and O(n) respectively. For Problem (iii), our proposed algorithm runs in O(nlogn) time and O(n) space.     

Families,social life,and well-being at older ages

As people age, many aspects of their lives tend to change, including the constellation of people with whom they are connected, their social context, their families, and their health—changes that are often interrelated. Wave I of the National Social Life, Health, and Aging Project (NSHAP) has yielded rich information on intimate ties, especially dyads and families, and on social connections generally. Combined with extensive biological and other health measures, NSHAP enables researchers to address key questions on health and aging. We begin with recent findings on intimate dyads, then move to social participation, and finally to elder mistreatment. Among dyads, we find that whereas sexual activity drops sharply with age for both women and men, gender differences in partner loss as well as psychosocial and normative pressures constrain women’s sex more than men’s. However, surviving partnerships tend to be emotionally and physically satisfying and are marked by relatively frequent sex. In contrast to sex, nonsexual intimacy is highly prevalent at older ages, especially among women. Older adults are also socially resilient—adapting to the loss of social ties by increasing involvement with community and kin networks. Despite these social assets, older adults remain vulnerable to mistreatment. Overall, these findings yield a mixed picture of gender-differentiated vulnerabilities balanced by proactive adaptation and maintenance of social and dyadic assets.     

Evidence for an Incipient Decline in Numbers of Missing Girls in China and India

The apparently inexorable rise in the proportion of “missing girls” in much of East and South Asia has attracted much attention among researchers and policymakers. An encouraging trend was suggested by the case of South Korea, where child sex ratios (males to females under age 5) were the highest in Asia but peaked in the mid‐1990s and normalized thereafter. Using census data, we examine whether similar trends have begun to manifest themselves in the two most populous countries of this region, China and India. The data indicate that child sex ratios are peaking in these countries, and in many subnational regions are beginning to trend toward lower, more normal values. This suggests that, with continuing economic and social development and vigorous public policy efforts to reduce son preference, the “missing girls” phenomenon could eventually disappear in Asia.     

Maternal Cocaine Use and Infant Behavior

This study examined the impact of maternal cocaine use and associated risk factors such as polysubstance use, maternal functioning, and caregiving on affect regulation during infancy. Participants were 45 mother‐infant dyads (19 cocaine exposed and 26 control infants) recruited at birth. Observations and maternal reports of infant behavior were obtained at 2 and 7 months of age, along with measures of pre‐ and postnatal substance use, maternal functioning, and caregiving stability. Maternal cocaine use accounted for significant variance in infant positive affect at 2 months. Other substance use and gestational age predicted infant distress to novelty and arousal during developmental assessments. At 7 months, the impact of prenatal cocaine exposure on infant affect regulation was mediated by postnatal alcohol use and caregiving stability. These findings, if replicated, suggest that 1 pathway to later problem behavior reported among substance‐exposed children may be through early regulatory problems and the quality of postnatal caregiving.     

Community mentors as coaches: transforming gender norms through cricket among adolescent males in urban India

Addressing violence against women and girls (VAWG) through the medium of male team sport may be a promising strategy for addressing interpersonal violence and gender norms transformation in urban communities. Parivartan is a violence prevention programme in a large slum community in Mumbai, India, which works with men and boys to reduce violence and promote gender-equitable attitudes and beliefs via membership of a cricket team and mentoring from coaches. This article discusses findings from a recent evaluation of the programme.     

Criticality in games with multiple levels of approval

In this article, criticality within a voting game is rigorously defined and examined. Criticality forms the basis of the traditional voting power measures frequently employed to analyse voting games; therefore understanding criticality is a pre-requisite to understanding any such analysis. The concept of criticality is extended to encompass games in which players are allowed to express multiple levels of approval. This seemingly innocuous extension raises some important questions, forcing us to re-evaluate exactly what it means to be critical. These issues have been largely side-stepped by the main body of research as they focus almost exclusively on ‘yes/no’ voting games, the so called single level approval voting games. The generalisation to multilevel approval voting games is much more than just a theoretical extension, as any single level approval game in which a player can abstain is in effect a multilevel approval voting game.     

Estimation of demographic measures for India, 1881-1961, based on census age distributions

Abstract India is one of the very few developing countries which have a relatively long history of population censuses. The first census was taken in 1872, the second in 1881 and since then there has been a census every ten years, the latest in 1971. Yet the registration of births and deaths in India, even at the present time, is too inadequate to be of much help in estimating fertility and mortality conditions in the country. From time to time Indian census actuaries have indirectly constructed life tables by comparing one census age distribution with the preceding one. Official life tables are available for all the decades from 1872-1881 to 1951-1961, except for 1911-1921 and 1931-1941. Kingsley Davis(1) filled in the gap by constructing life tables for the latter two decades. He also estimated the birth and death rates ofIndia for the decades from 1881-1891 to 1931-1941. Estimates of these rates for the following two decades, 1941-1951 and 1951-1961, were made by Indian census actuaries. The birth rates of Davis and the Indian actuaries were obtained basically by the reverse survival method from the age distribution and the computed life table of the population. Coale and Hoover(2), however, estimated the birth and death rates and the life table of the Indian population in 1951 by applying stable population theory. The most recent estimates of the birth rate and death rate for 1963-1964 are based on the results of the National Sample Survey. All these estimates are presented in summary form in Table 1.     

Dimensions of women’s autonomy and the influence on maternal health care utilization in a north indian city

The dimensions of women's autonomy and their relationship to maternal health care utilization were investigated in a probability sample of 300 women in Varanasi, India. We examined the determinants of women's autonomy in three areas: control over finances, decision-making power, and freedom of movement. After we control for age, education, household structure, and other factors, women with closer ties to natal kin were more likely to have greater autonomy in each of these three areas. Further analyses demonstrated that women with greater freedom of movement obtained higher levels of antenatal care and were more likely to use safe delivery care. The influence of women's autonomy on the use of health care appears to be as important as other known determinants such as education.     

The Decline of Son Preference in South Korea: The Roles of Development and Public Policy

For years, sex ratios at birth kept rising in South Korea despite rapid development. We show that this was not an anomaly: underlying son preference fell with development, but the effect of son preference on sex ratios at birth rose until the mid‐1990s as a result of improved sex‐selection technology. Now South Korea leads Asia with a declining sex ratio at birth. We explore how son preference was affected by development and by public policy. Decomposition analysis indicates that development reduced son preference primarily through triggering normative changes across society—rather than just in individuals whose socioeconomic circumstances had changed. The cultural underpinnings of son preference in preindustrial Korea were unraveled by industrialization and urbanization even as public policies sought to uphold the patriarchal family system. Our results suggest that child sex ratios in China and India may decline before those countries reach South Korean levels of development, since the governments of both countries vigorously promote normative change to reduce son preference.
