New and emended species of Jurassic planktonic foraminifera
No full textTwo Jurassic planktonic genera are emended and two new species and one subspecies of Jurassic planktonic foraminifera are defined. The genera are Globuligerina Bignot and Guyader 1971 and Conoglobigerina Morozova 1961 and the two new species are Globuligerina tojeiraensis Gradstein and Conoglobigerina grigelisi Gradstein. Both new species commonly occur in the Tojeira Formation, Montejunto, Portugal. The Tojeira Formation is a deeper marine shale unit of Early Kimmeridgian age. The new subspecies is Globuligerina oxfordiana calloviensis Gradstein, from the Callovian in the Crimea and Ukraine. A detailed description is provided for one of the historically oldest Jurassic taxa, Conoglobigerina helvetojurassica Haeusler 1881, re-discovered in the Birmenstorfer Schichten of Middle Oxfordian age near Mönthal, Canton Aargau, Switzerland. A neotype is proposed for this taxon. One specimen of C. helvetojurassica may have been attached to a substrate during a later part of its life cycle. The same Birmenstorfer Schichten also yielded two small specimens of an unknown planktonic genus with longitudinal ribs along its pyramidal and probably triserial test. The test is microperforate and wall textures reticulate. The types and type locality of ‘Globuligerina’ stellapolaris Grigelis, described from Northwestern Russia should be carefully investigated, to determine if it is a Late Jurassic or a Late Cenozoic taxon

Parents’ assets and child marriage: are mother’s assets more protective than father’s assets?
No full textChild marriage places girls at an increased risk for dropping out of school early, sexually transmitted infections, teenage childbirth, and accompanying childbirth complications, including maternal mortality. The determinants of child marriage are not clearly understood, which hinders efforts to mount effective interventions. This study examined the link between economic resources and child marriage by investigating whether maternal and paternal asset ownership were longitudinally associated with daughters’ child marriage in Ethiopia. Drawing upon household bargaining theory, it was hypothesized that maternal assets would be more protective of daughters’ child marriage than paternal assets. Data for 4,293 girls from the nationally representative Ethiopia Socioeconomic Survey, fielded in 2011 and 2014, were employed. Logistic regression and instrumental variable analyses were used to examine the relationship between transition into child marriage during the study period and maternal and paternal assets, controlling for child-, family-, and community-level characteristics. Results show that a one standard deviation increase in mother’s assets was associated with 37–53% lower odds of daughter’s child marriage whereas a one standard deviation increase in paternal asset holdings was associated with 0–37% higher odds of daughter’s child marriage. Effects were strongest in regions where the dominant mode of marriage payments is bride price. These results suggest that the link between economic resources and child marriage depends on the gender of the parent who owns the resources. This study also highlights the interconnectedness of two targets of the gender equality Sustainable Development Goal—improvement of women’s ownership of assets and the elimination of child marriage—and suggests that the realization of one gender equality target could have implications for other targets.Peer reviewe
Sex composition of children and spousal sexual violence in sub-Saharan Africa
No full textObjective
In societies with a cultural preference for sons over daughters, women who do not bear sons may be at increased risk for spousal violence. This study examined whether women with daughters only are at an elevated risk for spousal sexual violence compared to women with sons only in sub-Saharan Africa. The study tested the hypothesis that the association between sex composition of children and spousal sexual violence would be observed only in large families.
Methods
Data were from the most recent (as at February, 2016) Demographic and Health Surveys conducted in 22 sub-Saharan African countries for 37,915 women. Odds ratios comparing experience of spousal sexual violence of women with sons only to those with daughters only were estimated, separately for women with three or fewer children and those with four or more children, controlling for age, age at first cohabitation, age at first birth, educational attainment, urban residence, and household wealth.
Results
Having daughters only was associated with a greater likelihood of spousal sexual violence among women with many children (adjusted odds ratio [AOR] = 1.53; 95% CI = 1.02–2.30) but not among those with few children (AOR = 0.92; 95% CI = 0.82–1.04).
Conclusions for practice
A higher risk of sexual violence for women without sons suggests that son preference may have implications on women’s health and wellbeing. Efforts to further understand and address increased risk of sexual violence for women without sons should consider son preference and intra-couple conflict concerning fertility intentions.Peer reviewe
Disability among children of immigrants from India and China: is there excess disability among girls?
No full textWe investigate whether there is excess morbidity among daughters of Indian or Chinese immigrants in the US by studying the prevalence of disability among children. We use data from the 2012–14 American Community Surveys on approximately 20,000 US-born children of Indian and Chinese immigrants. Children of US natives are used as a comparison group to account for innate differences in disability between the sexes. Results indicate that there is excess disability among daughters compared with sons among children of Chinese immigrants and children of immigrants from northern or western Indian states; this excess disability declines with younger age at arrival or longer exposure to the host country. Analysis using children of Filipino immigrants as an alternative comparison group yields similar excess disability rates for females.Peer reviewe
Effect of Food Subsidies on Micronutrient Consumption
No full textIn this article, we study the effect of an exogenous increase in wheat and rice price subsidy to poor families resulting from a targeted food price subsidy program in India called the Targeted Public Distribution System (TPDS) on micronutrient intake in low-income families. Descriptive results show that wheat and rice have one of the lowest micronutrient density scores, suggesting that these are poor suppliers of micronutrients. Empirical analysis suggests that the increase in subsidy amount of Rs. 15-18 resulting from the TPDS expansion lowered calcium intake by 12-14 percent and had negligible to small (often negative) effects on the consumption of most micronutrients.Peer reviewe
Culture, labor supply, and fertility across immigrant generations in the United States
No full textRecent immigration to the United States and other developed nations has increasingly been from countries that have relatively traditional gender norms. This study uses data from the Current Population Survey for 2000–14 to investigate how source-country gender norms influence the labor supply and fertility of married women across immigrant generations in the US. It finds that immigrants’ and descendants’ labor supply and fertility are associated with the female-to-male labor force participation ratio and total fertility rate in the source country; importantly, the association declines across successive generations. Husbands’ source-country characteristics are also associated with the labor supply and fertility of immigrant women. These findings indicate evolution and assimilation of traditional gender norms in the long run.Peer reviewe
New insights into the taxonomy and evolution of Jurassic planktonic foraminifera
No full textAbstract Globuligerina glinskikhae nov. sp. Gradstein & Waskowska and Globuligerina waskowskae nov. sp. Gradstein are new species of Jurassic planktonic foraminifera from the Middle Jurassic of Dagestan and Poland. G. glinskikhae nov. sp. with its remarkable ‘protoglobigerine’ test may be an early evolutionary offshoot of Globuligerina oxfordiana (Grigelis). It may be an index taxon for upper Bajocian through Bathonian strata in Eastern Europe and Southwest Asia, and might be recognizable also in thin sections. We consider G. waskowskae nov. sp. to be a possible forerunner of Conoglobigerina helvetojurassica (Haeusler), the first planktonic foraminiferal species with a reticulate wall texture. Currently, is only known from Poland. In some localities, specimens of G. oxfordiana and of G. glinskikhae nov. sp. posses an additional apertural opening, often lacking a rim; its function is enigmatic. The postulated lineage from Jurassic Globuligerina balakhmatovae (Morozova) to Cretaceous Clavihedbergella eocretacea Neagu is refined with the description of Petaloglobigerina simmonsi nov. gen., nov. sp. Gradstein from the Kimmeridgian of Portugal. The evolutionary transition from G. balakhmatovae to P. simmonsi occurs by means of the ontogenic development of a petaloid test, with a pronounced flattening of the whorl with ovate chambers, the last ones often offset and twisted. Jurassic planktonic foraminifera, now known to consist of three genera and 12+ species underwent long periods of stasis, interrupted by late Bajocian, mid-Oxfordian and early Kimmeridgian evolution. The three ‘stasis and root’ taxa G. oxfordiana, G. bathoniana and G. balakhmatovae are geographically widespread in lower to mid palaeo-latitudes, and stratigraphically long ranging within the Middle and Late Jurassic. Modern digital microscopes, with co-axial and side LED lighting and excellent image stacking software are important tools in the study of Jurassic planktonic foraminifera, and fast and cost-effective communication tools in modern micropalaeontology.
