Chinese housing prices rose by over 10 percent per year in real terms between 2003 and 2014 are now two ten times higher than the construction cost of apartments. At same time, developers built 100 billion square feet residential estate. This boom has been accompanied a large increase number vacant homes, held both households. may turn out to be bubble followed crash, yet that future is far from certain. The demand for estate China so strong current might sustainable, especially given sparse...

Results of clay mineralogy, major element geochemistry, and Sr Nd isotopes in 93 argillaceous samples collected from drainage basins the Pearl, Red, Mekong rivers reveal different degrees chemical weathering Southeast Asia despite similar climate conditions across these regions. The kaolinite/illite ratio, illite chemistry index, crystallinity can be used as indicators intensity. These mineralogical proxies combined with K 2 O/(Na O + CaO) molar index alteration (CIA), trends observed...

By examining the ethnic identity of authors in over 2.5 million scientific papers written by US-based from 1985 to 2008, we find that persons similar ethnicity coauthor together more frequently than predicted their proportion among authors. The greater homophily is associated with publication lower-impact journals and fewer citations. Meanwhile, locations longer reference lists get published higher-impact receive These findings suggest diversity inputs author ethnicity, location, references...

This paper utilizes the county-by-county rollout of China's New Rural Pension Scheme (NRPS) and finds that, among age-eligible people, pension scheme leads to higher household income food expenditure, less farmwork, better health, lower mortality. In addition, NRPS shifts age-ineligible adults from farmwork nonfarmwork but does not significantly affect their income, or health. No significant evidence shows that affects private transfers health behaviors. These findings provide relevant...

Given the fact that more and governments invest heavily in e-government design implementation, has become an evolving important research area IS field. Most, if not all, currently published strategies are based on successful experiences from developed countries, which may be directly applicable to developing countries. Based a literature review, this study summarizes differences between developed/developing It identifies key factors for implementation proposes framework. As demonstration, we...

Long‐term records show high concentrations of dissolved major elements in the Changjiang (Yangtze River) and Huanghe (Yellow River). The drainage basin is characterized by intense weathering erosion carbonates evaporites, while silicates over main source Changjiang. rock/soil composition tectonics are more important than atmospheric precipitation affecting element these two rivers. Compared with other large rivers world, suspended sediment loads reveal physical chemical Chinese continent.

In this paper, we build on the literature that examines associations between height and health outcomes of elderly. We investigate shrinkage at older ages with socioeconomic status, finding for both men women is negatively associated better schooling, current urban residence, household per capita expenditures. then relationships pre-shrinkage height, shrinkage, a rich set respondents, positively poor across variety outcomes, being especially strong cognition outcomes.

This study examines the ethnic identity of authors in over 2.5 million scientific papers written by US-based from 1985 to 2008, a period which frequency English and European names among fell relative China other developing countries.We find that persons similar ethnicity co-author together more frequently than predicted their proportion authors.Using measure homophily for individual papers, we greater is associated with publication lower impact journals fewer citations, even holding fixed...

This paper examines an unintended response to the one-child policy in China: births of twins. Analysis population census data shows that has accounted for more than one-third increase reported twins since 1970s. Investigation using birth spacing with prior and height difference within suggests is partly due parents reporting regularly spaced children as avoid violation punishment. The study highlights possibility individual behavioral undesirable government policies potential social consequences.

Abstract This study considers the experience of china's one-child policy to examine how fertility restrictions affect economic and social outcomes over a lifetime. Using variations in these penalties across provinces time, we find that exposure stricter when young leads higher education levels, more white-collar jobs, delayed marriage, lower rates. Further consequences include rates residing with elderly household income, consumption, savings. Finally, early life increases female...

High-fine particulate matter (PM2.5) pollution has become the main object of damaging atmospheric environment and endangering human health. Accurate prediction spatial variability PM2.5 concentrations using high-performance models is crucial for prevention control pollution. In this paper, in order to avoid uncertainty caused by artificially setting parameters model, a new hyper-parameter optimization extreme gradient boosting (HPO-XGBoost) model concentration was proposed. We used aerosol...

Current conceptualizations of the biological basis for insomnia typically invoke central nervous system and/or autonomic arousal. Acupuncture may represent a unique avenue treatment poor sleep by virtue its direct effects on peripheral nerves and muscles, which, in turn, modulate tone activation. In this review, we summarize both basic clinical research indicating that acupuncture exerts profound influences via wide variety potential neural hormonal mechanisms have great relevance modulation...

Background and Purpose— Current literature provides mixed evidence on disparities by race/ethnicity socioeconomic status in discharge outcomes after hospitalization for acute ischemic stroke. Using comprehensive data from 8 states, we sought to compare inpatient mortality length of stay status. Methods— We examined all 2007 hospitalizations stroke nonfederal care hospitals Arizona, California, Florida, Maine, New Jersey, York, Pennsylvania, Texas. Population was stratified (non-Hispanic...
