Factor Decomposition of Rural Income Inequalities in China

A Chinese geographer explores changes in inter-provincial rural income inequality in China since the late-1970s economic reforms by decomposing it into different component factors based on the Gini index (more specifically, into contributions by different income sources: wages, household operations, properties, and transfers). The influence of each factor on inequality changes is further decomposed into its structure effects and its real inequality effects. Quantitative analysis then makes it possible to determine the relative influence of each component on changes in rural provincial inequality over time.     

Unique marine taphonomy in human skeletal material recovered from the medieval warship Mary Rose

The effect of skeletal exposure in a marine environment is an area of taphonomy that has been little investigated at the microscopic level. Understanding the peri‐mortem and subsequent post mortem history of deposition and/or redeposition is extremely important for event reconstruction and to identify deliberate or accidental redeposition. The material used for this study comes primarily from the Mary Rose shipwreck (a marine mass fatality dated AD 1545), and forensic material recovered from marine, lacustrine and terrestrial contexts is retrospectively referenced. Work presented here outlines a definitive type of marine exposure seen in temperate shallow off‐shore and intertidal marine contexts, and illustrates how it may be differentially identified from terrestrial deposition and exposure. Furthermore, the effects of rapid deposition on skeletal remains have been documented, and results indicate that marine organism fouling activity can be fully inhibited by rapid deposition of sediment. The responsible organism itself remains unidentified, but produces tunnels which are peripheral in their distribution and maintain fixed dimensions and morphology and are here associated with marine exposure. This type of microstructural change is unique and is not found in terrestrial or freshwater contexts. The study demonstrates a taphonomic microstructural change to bone and teeth which may be identified microscopically and interpreted as evidence of marine exposure. Secondarily, the history of depositional exposure between the two main Tudor layers has provided a new level of detail concerning exposure and site formation processes. The earliest Tudor layer formed rapidly over a period of months and contained no evidence of microstructural tunnelling, whereas microstructural tunnelling was seen exclusively in the second Tudor layer, formed over a period of decades, a period during which the ship's hull collapsed and a more open marine environment dominated.

A Tale of Two Cities: A Decomposition of Recent Fertility Changes in Shanghai and Hong Kong

In the past 20 years, Hong Kong and Shanghai's total fertility rates (TFR) have undergone drastic changes: first declining and then rebounding. We use a decomposition method to assess changes in the TFRs of these two cities during the period 1990–2010. During the period of decline from 1990 to 2000, the decrease in marital fertility rate (MFR) was the major cause behind Shanghai's TFR decline; the decrease in nuptiality and MFR were equally responsible for the decline in Hong Kong's TFR. During the 2000–2010 period, although the decline in nuptiality exerted downward pressure on TFR, both cities experienced an increase in TFR mainly due to an increase in the MFR. Analysis of the difference in TFR between the two cities in 2010/2011, also reveals that Hong Kong's marriage delay has a negative impact on fertility and it is the higher MFR that leads to a higher TFR than Shanghai's TFR. It also shows that a reduction of first- and second-order births is equally responsible for Shanghai's lower MFR. Despite the one-child policy in Shanghai, some couples continue to postpone their first births, while others have even chosen to be childfree (a preferred term to ‘childless’). The tempo distortion is diminishing more prominently in Hong Kong, while the decline in fertility aspiration adds much uncertainty to future fertility trends in Shanghai.     

Wandering bones: archaeology,forensic science and Moche burial practices

The focus of this study is a sample of human burials from the Precolumbian archaeological site of San José de Moro, Perú. This site is located in the coastal desert of northern Perú and this sample dates to the latter half of the Moche period (AD 450–750). Upon discovery, many of the burials from this site were found to demonstrate various degrees of disarticulation. Stratigraphic analysis demonstrates that this disturbance cannot be the product of post-depositional forces. An analysis of the distribution of the bones within the tombs, and a review of the process of corporeal decomposition suggests that the disturbance happened before the bodies were interred. The results indicate that the cadavers were wholly or partially mummified before burial, and that disarticulation occurred as the brittle, mummified body was manoeuvered into the tomb. The body was mummified either as a deliberate measure before transporting the corpse over long distances, or as a natural product of the curation of the body above ground in a dry environment, during an extended funeral ritual. This combination of archaeological and forensic analysis yields important new insights into the burial practices of the Moche. © 1998 John Wiley & Sons, Ltd.     

Macroscopic and microbiological alterations of bird and small mammal bones buried in a Cerrado biome (south western Brazil)

In this paper, we present the results of an experimental approach developed to study the macroscopic and microbiological alteration of bird and small mammal bones buried under a Cerrado biome. The first experiment evaluated the macroscopic alteration of cooked and fresh carcasses buried through the dry and rainy seasons. The second experiment analyzed the mycobiota associated to the decomposition of a complete bird that remained buried for almost a year. Results show that in tropical forest environments: 1) bone structure and pre-taphonomic factors determine its differential alteration by biochemical processes; 2) fungal populations associated to the decomposition of animal remains depend on soil chemistry and ecological dynamics; 3) even in a corrosive environment, bird bones are more capable of surviving to several mycological decomposition steps.     

Nowtopia: Strategic Exodus?

Abstract: Nowtopia identifies a new basis for a shared experience of class. Specifically, the exodus from wage labor on one side, and the embrace of meaningful, freely chosen and “free” (unpaid) work on the other. A product of three decades of decomposition of the working class, nowtopians are different from “drop‐outs” in general, or surplus populations that constitute the necessary “outside” to capital, in their conscious withdrawal from capitalist culture and concerted rejection of the value form. In emergent convivial “nowtopian” communities, largely grounded in unpaid practical work which creatively meets needs such as transportation (the bicycling subculture), food (urban gardening/agriculture), and communication (open‐source communities), we see a gradual reversal of the extreme atomization of modern life. While facing the threat of corruption via re‐integration into the system, this constellation of practices, if taken together, is an elaborate, decentralized, uncoordinated collective research and development effort exploring a potentially post‐capitalist, post‐petroleum future.     

Decomposing the Rural-Urban Differentials in Childhood Malnutrition in India, 1992–2006

Using data from multi-waves of the National Family Health Survey conducted in India between 1992 and 2006, this study examines the pattern of rural–urban differentials in childhood malnutrition in India over time. Furthermore, it identifies the factors responsible for the rural–urban gap in childhood malnutrition and quantifies their contribution. The result shows a considerable and widening gap in childhood malnutrition across rural–urban residence in the country over the study period. The rural–urban gap in childhood malnutrition has narrowed in a few states whereas it widened in most states over time. The economic status of the household and parental education was the most significant contributors to the rural–urban gap in childhood malnutrition in India. Based on the findings, this study suggests that to reduce the rural–urban gap in childhood malnutrition, focus should be given to the rural poor.     

我国能源强度区域差异影响因素的实证研究——以陕西和广东为例

本文通过完全因素分解法,对陕西省和广东省1997-2006年能源强度差异的影响因素进行了实证研究。研究结果表明陕西各产业能源强度过高是陕西能源强度高于广东的主要因素,而工业结构中高耗能产业比重较大是其次要因素。因此,陕西要达到国家提出的五年内单位GDP能耗降低20%的战略目标,一方面需要运用价格、税收和财政补贴等综合的调控手段推动节能技术的开发和利用,建立合理的能源价格体系以有效的降低各产业部门的能源强度,另一方面应根据陕西的要素禀赋进行适当的产业结构调整。     

INEQUALITIES IN CHILD MORTALITY IN INDIA

This paper measures the degree of inequality in child mortality rates across districts in India using data from the 1981, 1991 and 2001 Indian population censuses. Results show that child mortality is more concentrated in less developed districts in all three census years. Furthermore, between 1981 and 2001, the inequality in child mortality seems to have increased to the advantage of the more developed districts. In the decomposition analysis, it is found that while a more equitable distribution of medical facilities and safe drinking water across districts has contributed to reducing inequality in child mortality between 1981 and 1991, different levels of structural change among districts have been responsible for a very large part of the inequality in child mortality to the advantage of the more developed districts in all three census years. The paper concludes with some brief comments on the policy implications of the findings.     

Decomposing the crude divorce rate in five countries: Singapore,Taiwan, South Korea,the UK,and Australia

Over the past few decades, the level of divorce, measured by the crude divorce rate (CDR), has increased dramatically in both the East and the West, but has recently appeared to fall or level off in some countries. To investigate whether the recent decline or stabilisation of the CDRs reflects the real trends in divorce risk, a decomposition analysis was conducted on the changes in the CDRs over the past 20 years on two western and three East Asian countries, namely, the UK, Australia, Taiwan, South Korea, and Singapore. The following is observed: the decline in the CDRs of the UK and Australia in the 1990s, and of Taiwan and Korea in the 2000s, was mainly due to shrinkage in the proportion of the married population rather than any reduction in divorce risk; only Australia experienced a genuine reduction in divorce risk between 2001 and 2011; and the continuous increase of Singapore’s divorce level between 1990 and 2010 may be is an unintentional effect of the government’s marriage promotion policies. The shift in the population age structure, and more importantly, the drastic decline in marriage, has seriously distorted the CDRs, making them unreliable indicators for monitoring divorce trends.
