Do multiparty elections improve human development in autocracies?

Improvements in human development under democratic institutions are often attributed to electoral contestation. We evaluate the effect of multiparty contestation on infant mortality in the authoritarian context. Contrary to what extant scholarship argues, we find no evidence that multiparty elections in authoritarian regimes reduce infant mortality. Specifically, we show that electoral autocracies do not produce better infant mortality outcomes compared to closed autocracies holding no multiparty elections. We also demonstrate a non-monotonic effect of electoral competition on infant mortality: Infant mortality increases in levels of electoral contestation common in electoral authoritarian regimes and decreases only at levels of contestation that are nearly exclusive to democracies. Finally, we show that increases in infant mortality in electoral authoritarian regimes operate partially through increased political violence and reduced state capacity.     

The use of geographic information systems as a forensic tool to investigate sources of marine mammal entanglement in fisheries

Commercial fisheries represent a significant anthropogenic threat to marine mammal survival. Causes of marine mammal mortality are commonly determined by detailed necropsies of stranded carcasses. Gross evidence of entanglement in a fishery might include gear attached to the body, internal indications of asphyxiation and trauma, or gear markings on the epidermis. As gear is often fishery-specific, wound patterns on the epidermis that are created by entanglements in fishing gear may serve to identify possible sources of mortality. For this study, tools within the Environmental Systems Research Institute, Inc. (ESRI) ArcMap GIS software were used to create maps that outline impressions that fishing gear can leave on the epidermis of entangled marine mammals. These maps can subsequently be used to identify possible sources of fishery entanglement for the many marine mammals that wash ashore without gear attached to their carcass. Entanglement wound patterns can be visually compared with fishing gear characteristics; however, differences in scale and image quality can introduce subjectivity that might hinder source identification. The technique described herein provides an objective way to outline the unique characteristics of fishing gear and their associated wounds on entangled marine mammals. Additionally, spatial relationships are preserved as the maps are adjusted to varying scales. Whereas the initial protocol required time-consuming digitization of the outline and visual determination of the pattern interface, this new, semiautomated technique saves analyst effort and minimizes error.

Denied their ‘natural nourishment’: religion,causes of death and infant mortality in the Netherlands, 1875–1899

At the end of the nineteenth century, infant mortality rates started to fall rapidly in the Netherlands. Unfortunately, not all regions benefited from this development. High infant death in the Roman Catholic provinces of North-Brabant and Limburg has often been ascribed to a growing reluctance of Catholic mothers to breastfeed their infants after 1870. This was supposedly caused by the combination of a strict, prudish Roman Catholic norm prohibiting women from baring their breasts and a refusal to accept new medical insights into healthy childcare. The food given to weaned children was generally of such poor quality that many infants succumbed to gastrointestinal diseases. Consequently, infant mortality rates caused by water- and food-borne infectious diseases would have been higher amongst weaned babies. By using recently digitised municipal cause-of-death registration statistics, it is possible to see if there are, indeed, indications of a shift in breastfeeding patterns after 1870. First, the authors look at infant deaths from all causes to see whether Roman Catholic municipalities underwent a rise in the mortality of children under the age of one. Second, the authors do the same for cause-specific infant mortality from typhus, typhoid fever, diarrhoea, dysentery, acute diseases of the digestive system and cholera. Based on the outcomes, there was no homogenous rise in infant mortality in all Roman Catholic municipalities. Furthermore, there is no indication that infant mortality due to digestive diseases increased uniformly in all Roman Catholic communities between 1875 and 1899. Either some communities were able to counteract the negative effects of a shift towards weaning or changes in breastfeeding patterns were not a specific Roman Catholic phenomenon at all.     

Sex differentials in phthisis mortality in England and Wales, 1861–1870

In the mid-nineteenth century phthisis, or pulmonary tuberculosis, was the single most important cause of death in England and Wales. It was widely distributed geographically though some areas were worse affected than others. This paper explores aspects of the geography of phthisis mortality in England in the second half of the nineteenth century, with particular attention to the sex differential in mortality from this cause. Phthisis is often thought of as a disease of young women, and throughout much of England and Wales, especially in agricultural areas, women aged between 15 and 40 years were especially vulnerable. However the sex ratio of deaths from phthisis varied greatly from place to place and, in some places where phthisis was prevalent, men rather than young women were at the greatest risk of death. Phthisis mortality was sufficiently important that the geography of the overall sex differential in mortality was to a considerable extent determined by the geography of the sex differential in phthisis mortality. Where phthisis mortality disadvantaged females, the overall sex differential between male and female mortality was small or even negative; where phthisis mortality disadvantaged males, the overall sex differential was large. The paper then considers explanations of geographical variations in the sex differential in phthisis mortality. It is not clear that these are best explained by a ‘bargaining-nutrition’ account which holds that young women in poor households were especially vulnerable to mortality from phthisis because their weak intra-household bargaining position compromised their nutritional status. Other factors, such as the return migration to their native areas of out-migrants who became sick with the disease, and working conditions, especially for females, may have been more important. The final part of the paper considers the implications of the results for explanations of the decline of phthisis mortality between 1860 and 1900.     

In Vitro Effects of Household Products on Calliphoridae Larvae Development: Implication for Forensic Entomology

Several parameters can delay the first arrival of flies on a corpse and the subsequent development of the larvae. This study focuses on the development of Lucilia sericata (Diptera: Calliphoridae) (Meigen, 1826) on household chemical‐contaminated substrates. bleach, perfume, hydrochloric acid, caustic soda, insecticide, mosquito repellent, and gasoline in quantities consistent with an amount that could possibly be spilled on a corpse were mixed with beef liver to simulate contaminated fleshes. Larvae were bred at 25°C on these media until emergence. Four developmental parameters were followed: survival rates, development times, sex ratios, and adult sizes. Hydrochloric acid, insecticide, and gasoline killed all larvae. In low quantities, caustic soda and mosquito repellent increased the development time and decreased the adult size. However, high quantities of these chemicals killed all larvae. Lastly, bleach and perfume did not affect the survival rate and barely impacted the development time or adult size. These results demonstrate common household products spilled on a corpse can strongly affect the development of Calliphoridae larvae. The effects of such products should be considered in forensic entomology cases.     

Childbirth transformation and new style midwifery in Beijing, 1926 – 1937

ABSTRACT

This article offers a comparative analysis of the transformation of midwifery practices in Beijing city and its rural neighborhood in China between 1926 and 1937. From the 1920s onwards, impelled by supports of governments, academic groups and foreign foundations, a reform of midwifery practices was triggered across China. Beijing was one of the forerunners in this reform. Through examining the midwifery regulations, the new style midwifery service, the midwife education/training programs, as well as the consequential influences on birth attendants and birth outcomes (neonatal, infant and maternal mortality rates) in Beijing’s first health district and the nearby Qinghe district, this article shows that in the urban district the trained birth attendants performed better than the untrained personnel in preventing neonatal deaths. Also, the growing use of trained midwifery contributed to the reduction of infant and maternal mortality rates in the urban community. However, because of the paucity of sources of rural areas, such positive outcomes cannot be ascertained in the rural district. Yet an obvious urban-rural divergence in midwifery services and maternal care is still observed.     

Differential infant mortality viewed from an evolutionary biological perspective

Evidence from family reconstitution studies suggests that variations in infant mortality may reflect differences in parental solicitude. For various proximate reasons that might originate from emotional, material or social interests, parents may be inclined to invest differently in the survival of their offspring. Evolutionary theory holds that the behavior-regulating mechanisms that cause differential parental care operate in a biologically functional manner. They obey the biological imperative of striving to propagate one's own genetic material in the gene pool of the population to the best possible degree, in view of prevailing socioecological constraints. From a Darwinian point of view, differential parental investment can be best understood as a socioecologically contingent tactical measure within an adaptive, i.e., genetic fitness enhancing strategy. Therefore, human reproductive decisions remain poorly understood unless their biological function in the Darwinian fitness competition is taken into consideration.     

Infant and child mortality in Sudan： Case of central region

This paper uses households＇ data from central region of Sudan to examine factors that affect infant and child mortality. The education of mother and father, community variables and household income per adult are used. For this purpose, a household survey was conducted to collect data on the variables of interest from a random sample withdrawn from the study population. 600 questionnaires were distributed to households in one province of the region （out of five） where there are seven localities. The data has been analyzed using different statistical and econometric methods, including ordinary least squares method. The ordinary least squares found that child mortality is inversely associated with household income per adult, community variables and parental education. The effect of mother＇s education is more significant than father＇s education, mother＇s age is also found to be the most important factor that influences child mortality.     

Post-mortem radiological examination in infants:: Evidence of child abuse?

We examined the value of post-mortem radiological examination of infants who were brought in for medico–legal autopsy. Twenty children between the age of 1 month and 15 months died under the picture of SIDS. No radiological or other signs of previous child abuse were seen in our autopsy material. A fatal case of child abuse with several metaphyseal fractures is reported. Some fractures were not visible on gross examination, but could be demonstrated by radiography and histology. In our material no association between SIDS and child abuse was found. In suspected cases of child abuse, particularly rib fractures and metaphyseal fractures should be sought. We recommend that post-mortem radiography is performed in such cases. If fractures are demonstrated, they should be verified by histologic examination.
