Stable isotope insights (δ18O, δ13C) into cattle and sheep husbandry at Bercy (Paris,France, 4th millennium BC): birth seasonality and winter leaf foddering

Abstract

Bercy is a prehistoric village sited by the Seine river (Paris, France), whose main period of occupation was dated to the very beginning of the 4th millennium BC. The animal subsistence economy relied heavily on cattle husbandry, complemented by other species including sheep. Cattle and sheep isotopic history (δ¹³C, δ¹⁸O) was investigated at the seasonal scale, through sequential sampling in tooth enamel, providing new insights into seasonality of birth and diet. Sheep were lambing in mid-spring, only slightly later than expected from what is observed nowadays in temperate Europe at similar latitude. Cattle were born over a period spanning approximately six months, which was an unexpected result compared with a two to three months calving period in free-ranging cattle populations. The extension of the calving period might have been related to seasonal food supplementation. Some cattle and some sheep fed on a ¹³C-depleted resource in winter, potentially leafy fodder. A direct consequence of an extended calving period would be the availability of cow milk, which would have covered the whole year at Bercy. This is important information in a context where the exploitation of cattle milk by the human community was highly suspected from the demographic management of the herd.     

DAUGHTER DISCRIMINATION AND FUTURE SEX RATIO AT BIRTH IN INDIA

This paper examines recent trends in sex ratio at birth in all the major states of India, based on three rounds of the National Family Health Survey. It finds evidence of an increase in the ratio, particularly at the second-order birth among women having a first daughter in many states in the northwestern region of the country. Also, there are signs of daughter aversion emerging in Odisha, an eastern state. Based on parity progression ratios and the trend in sex selection, an attempt is made to estimate the peak of sex ratio at birth in India. With moderate intensification in sex selection in the northwestern region, sex ratio at birth is expected to reach a peak of 117–119 males per 100 females around the period 2021–2026. If, in addition, sex selection spreads further in the southeastern region, the sex ratio at birth in India could even increase to a level of 124.     

Spatial and environmental impacts on adverse birth outcomes in Ontario

This study assesses the overall spatial variations and neighbourhood‐level “hot spots” of low birth weight and preterm birth incidence within three public health units in Ontario, Canada. The analysis uses a stepwise approach of intra‐class correlation analysis, a spatial scan statistic, and multilevel spatial modeling. Results show that neighbourhood level variation accounts for only 2–3 percent of the total variation of adverse birth outcomes in the study area. However, strong spatial autocorrelation is observed at the neighbourhood level, and spatial clusters of relatively high adverse birth outcome rates exist in areas that are associated with environmental risks, including pollution sources and proximity to highways. Thus, although estimated neighbourhood impacts on adverse birth outcomes are small compared with those of individual‐level risks, local high potential environmental risk areas are identifiable. Environmental surveillance and spatial statistical analysis should be conducted regularly by local health authorities to identify and monitor the impact of environmental changes on health in general and on birth outcomes in particular. Specific community‐oriented health interventions may be required to reduce observed local health impacts.     

Transition in second birth intention in a low fertility context: the case of Jiangsu,China

When China’s decades-long one-child policy was replaced by a two-child policy, the circumstances under which women intend to have a second child become of great concern. This study examines the determinants of women’s second birth intention, as well as how the intention changes over time alongside changes in other life circumstances. Using panel data from the Jiangsu Fertility Intention and Behaviour Study (JFIBS, 2007, 2010), we find that women with more economic and familial/social resources are more likely to want a second child, while women who work in non-agriculture sectors and have higher decision-making power in the family are less inclined to have a second child. We also find that a sizeable increase of family income encourages women to upwardly revise their intention towards a desire for two children. The role of policy change on Chinese women’s second birth intention is also discussed.     

Women's autonomy,education and birth intervals in India

Using data from the third National Family Health Survey (NFHS-3) on currently married fecund women who have had at least one birth during 2001–2002 and Cox-proportional hazard models, this study examines the less researched association between women's autonomy and birth-to-conception intervals in India. It also examines whether women's autonomy mediates or moderates the relationship between education and birth-to-conception interval. Our results indicate that after adjusting for demographic and socioeconomic factors, women's autonomy was a significant predictor of birth-to-conception intervals, with higher autonomy positively associated with larger birth-to-conception intervals. Education of women was also independently associated with longer birth-to-conception intervals. However, this study did not provide any support to the general perception that women's autonomy mediates the association between women's education and birth-to-conception interval. Women's autonomy rather than being a mediator acted as a moderator in this association. Policy measures to increase the spacing between births should emphasise not only improving the education of women but also their autonomy.     

The Holocaust and the birth of Israel in British,Swedish and Finnish press discourse, 1947–1948

This article examines the way in which the Holocaust was linked to the process of the birth of Israel between 1947 and 1948 in the mainstream British, Swedish and Finnish press. By utilising a framework of comparative cultural history, this essay seeks to understand why different countries responded to the suffering of the Jews during the Second World War in such diverse ways. This essay also seeks to question the popular belief that the two events were intimately linked, and that the link was recognised in a straightforward manner. Hence, the study argues that although the press coverage sometimes managed to establish the connection between the two events, more typically the news was domesticated. In other words, the news had a transcendental and meta-historical character, working as an extension to each country's own self-understanding of Jews, Zionism and the Holocaust.     

BIRTH CONTROL,PREGNANCY AND ABORTION AMONG ADOLESCENTS IN CHIANG MAI,THAILAND

The authors studied more than 1750 young urban Chiang Mai residents regarding pre-marital sex, contraception and reproductive health outcomes. Almost two-thirds of the males had had sexual intercourse, compared to one-third of the females. Withdrawal was the most popular method of birth control followed by condom use. There were more females (30.5 per cent) reporting that they had been pregnant than males (17.5 per cent) reporting that they had caused pregnancies. Two-thirds of the respondents who had experienced or caused pregnancy reported that it ended in abortion. Almost half of those who had experienced abortion had induced it themselves, usually using illegal abortifacients. One-third went to a private clinic or hospital illegally. Self-induced abortions were sometimes associated with complications that were treated with pharmacy medications or severe complications requiring hospital treatment. Adolescents in northern Thailand need improved sexual health services and programmes. To be effective though, attention should also be given to underlying cultural attitudes toward sexuality and young people, especially women.
