ABSTRACT: Objective: To provide an empirical overview of the parenting landscape in rural China, focusing on 18- to 30-month-old children and their caregivers in rural Shaanxi province. Methods: We collected unique data on 1442 caregiver-toddler dyads in rural areas of Shaanxi province and examined caregiver attitudes toward parenting, sources of information about parenting, and interactive parenting practices, and how each of these differed across generations. We measured how parenting attitudes and sources of information informed parenting practices. Finally, we measured levels of child development in our sample and the association between parenting practices and children’s developmental outcomes. Results: Most of the caregivers did not engage with children in a way that encouraged early development. Caregivers rarely told stories, sang, or used toys to play with their children. Grandmothers were more stressed by the children in their care and engaged significantly less than mothers did in the 3 stimulating interactions. Professional sources of information about parenting were underutilized by all caregivers. We found high rates of developmental delay in our sample and showed that these delays were associated with the lack of caregiver engagement. Conclusion: Our findings suggest that the major economic and social shifts occurring in rural China have not led to a widespread prevalence of stimulative parenting practices. Although caregivers report positive attitudes toward child-rearing, reliable sources of scientific information are lacking. Our results show a troubling generational disconnect between the information-seeking behaviors and parenting practices of rural caregivers.

Efficient responses to climate change require accurate estimates of both aggregate damages and where and to whom they occur. While specific case studies and simulations have suggested that climate change disproportionately affects the poor, large-scale direct evidence of the magnitude and origins of this disparity is lacking. Similarly, evidence on aggregate damages, which is a central input into the evaluation of mitigation policy, often relies on country-level data whose accuracy has been questioned.

Current Diabetes Reports, 2019

With an estimated 84 million people suffering from diabetes in South Asia, the disease imposes substantial economic burdens on individuals, families, and society. Furthermore, since the disease burden increasingly occurs in the most productive midlife period, it adversely affects workforce productivity and macroeconomic development. Diabetes-related complications lead to markedly higher treatment costs, causing catastrophic medical spending for many households, thus underscoring the importance of preventing diabetes-related complications.

Wheat is the most important staple crop grown in Australia, and Australia is one of the top wheat exporting countries globally. Timely and reliable wheat yield prediction in Australia is important for regional and global food security. Prior studies use either climate data, or satellite data, or a combination of these two to build empirical models to predict crop yield. However, though the performance of yield prediction using empirical methods is improved by combining the use of climate and satellite data, the contributions from different data sources are still not clear.

Western observers have raised concerns over the rise and now predominance of Chinese state-backed bilateral lending in international infrastructure development. These range from China's growing geopolitical influence to the increasingly unsustainable debt levels of some of the nations receiving investments as part of the Belt and Road Initiative (BRI). In fact the BRI today is simply the next phase of a decades-long shift in the infrastructure sector towards China and away from traditional western development lending institutions.

Accurate measurements of maize yields at field or subfield scales are useful for guiding agronomic practices and investments and policies for improving food security. Data on smallholder maize systems are currently sparse, but satellite remote sensing offers promise for accelerating learning about these systems. Here we document the use of Google Earth Engine (GEE) to build “wall-to-wall” 10 m resolution maps of (i) cropland presence, (ii) maize presence, and (iii) maize yields for the main 2017 maize season in Kenya and Tanzania.

For U.S. intelligence agencies, the twenty-first century began with a shock, when 19 al Qaeda operatives hijacked four planes and perpetrated the deadliest attack ever on U.S. soil. In the wake of the attack, the intelligence community mobilized with one overriding goal: preventing another 9/11. The CIA, the National Security Agency, and the 15 other components of the U.S. intelligence community restructured, reformed, and retooled. Congress appropriated billions of dollars to support the transformation.

The ratio of plant carbon gain to water use, known as water use efficiency (WUE), has long been recognized as a key constraint on crop production and an important target for crop improvement. WUE is a physiologically and genetically complex trait that can be defined at a range of scales. Many component traits directly influence WUE, including photosynthesis, stomatal and mesophyll conductances, and canopy structure. Interactions of carbon and water relations with diverse aspects of the environment and crop development also modulate WUE.

Although students in rural and migrant schools in China generally have not performed well, a share of each cohort has been able to thrive in school and to test into academic high school and college. To understand the origins of persistence, specifically, why some students learn more than do others, researchers have identified certain sources of the problem. Few studies, however, have paid attention to the role that low levels of cognitive development of students play in their academic performance.

Background: Various types of near work have been suggested to promote the incidence and progression of myopia, while outdoor activity appears to prevent or retard myopia. However, there is a lack of consensus on how to interpret these results and translate them into effective intervention strategies. This study examined the association between visual acuity and time allocated to various activities among school-going children.
Methods: Population-based survey of 19,934 students in grade 4 and 5 from 252 randomly selected rural primary schools in Northwest China in September 2012. This survey measured visual acuity and collected self-reported data on time spent outdoors and time spent doing various types of near activities.
Results:  Prolonged (>60 minutes/day) computer usage (-0.025 LogMAR units, P = .011) and smartphone usage (-0.041 LogMAR units, P = .001) were significantly associated with greater refractive error, while television viewing and after-school study were not. For time spent outdoors, only time around midday was significantly associated with better uncorrected visual acuity. Compared to children who reported no midday time outdoors, those who spent time outdoors at midday for 31–60 minutes or more than 60 minutes had better uncorrected visual acuity by 0.016 LogMAR units (P = .014) and 0.016 units (P = .042), respectively.
Conclusions: Use of smart phones and computers were associated with declines in children’s vision, while television viewing was not. Statistically significant associations between outdoor time at midday and reduced myopia may support the hypothesis that light intensity plays a role in the protective effects of outdoor time.

Understanding the causes of economic inequality is critical for achieving equitable economic development. To investigate whether global warming has affected the recent evolution of inequality, we combine counterfactual historical temperature trajectories from a suite of global climate models with extensively replicated empirical evidence of the relationship between historical temperature fluctuations and economic growth. Together, these allow us to generate probabilistic country-level estimates of the influence of anthropogenic climate forcing on historical economic output.

Even as Notre Dame Cathedral was burning, pundits such as Ben Shapiro and Katie Hopkins began to mourn it as a “monument to Western civilization … built on the Judeo-Christian heritage” — describing the fire as symbolic of a “Judeo-Christian annihilation.” The president of Poland immediately called for rebuilding the cathedral as a symbolic reconstruction of Europe on its “

Linking individuals across historical datasets relies on information such as name and age that is both non-unique and prone to enumeration and transcription errors. These errors make it impossible to find the correct match with certainty. In the first part of the paper, we suggest a fully automated probabilistic method for linking historical datasets that enables researchers to create samples at the frontier of minimizing type I (false positives) and type II (false negatives) errors. The first step guides researchers in the choice of which varia-bles to use for linking.

We show that an information nudge increased the rate of American citizenship applications among low-income immigrants eligible for a federal fee waiver. Approximately half of the 9 million naturalization-eligible immigrants qualify for a federal programme that waives the cost of the citizenship application for low-income individuals.

Repetition is constitutive of human life. Both the species and the individual develop through repetition. Unlike simple recall, repetition is permeated by the past and the present and is oriented toward the future. Repetition of central actions and events plays an important role in the lives of individuals and the life of society. It helps to create meaning and memory. Because repetition is a central aspect of human life, it plays a role in all social and cultural spheres. It is important for several branches of the humanities and social studies.

The 1940s and 1950s were a revolutionary era in both access to and imagination of the underwater environment in the most modernized nations of the globe. This article examines new possibilities in the exhibition of the underwater environment in film thanks to new dive and filming technologies. It focuses on how the depths are portrayed as a setting in Richard Fleischer’s 20,000 Leagues under the Sea (1954), by the Disney studio, and Jacques-Yves Cousteau and Louis Malle’s The Silent World (1956).

This paper examines how social isolation in a non-Anglophone context where English is not the main language of instruction for local students but is for international students, has unintended consequences for social capital formation among the latter. What factors influence international student network formation in such places where linguistic barriers are institutionalised and what are their consequences not only during college but beyond, in shaping students’ career plans?

In recent years, researchers have begun to focus attention on trying to identify systematic factors that cause interventions to have different impacts in different contexts. In this paper, we seek to understand whether the age of principals at schools implementing nutrition-based interventions has an impact on program outcomes. To explore the relative effectiveness of younger and older school principals, we use data from five large-scale, nutrition-related randomized controlled trials (RCTs) involving 12,595 primary school students in 336 schools in rural China. Our results, using two age cut-offs for distinguishing young principals from old ones, indicate that improvements in the health and nutrition outcomes of students were significantly higher in schools with younger principals than in schools run by older principals (when using a cutoff of 40 years old). When using a cut-off of 45 years old, the point estimates of the impacts similarly suggest that young principals are more effective, although the results are not significantly significant. The results are similar when we look at the impact of disaggregated interventions in schools managed by young and old principals. The findings are clear that the interventions implemented by older principals are not more effective than those implemented by younger principals.

Background: The use of maternal health services can markedly promote the maternal health and safety, but there has been a low utilization rate in the ethnic rural areas of western China. Furthermore, the correlated factors have not been well studied. This study aims to assess factors related to the use of maternal health services among women in these areas.
Methods: A cross-sectional study of 68 villages in China’s western Sichuan province was conducted in September 2014. All qualifying women from each sample village were involved. A structured questionnaire was administrated in households through face-to-face interviews by trained enumerators to obtain information of use of maternal health services and related factors. Structural equation modeling (SEM) was used to evaluate the direct and indirect relationships between use of maternal health services and correlated factors.
Results: A total of 760 women from 68 villages were enrolled. The proportion of antenatal care (ANC), hospital delivery and postpartum visits were 68.94, 48.29 and 28.42% respectively. The SEM analysis demonstrated that social economic status (SES) (β= − 0.75, β< 0.01), ANC (β=0.13, β< 0.01), and time from home to the nearest hospital (β= − 0.09, β< 0.05), were positively correlated to hospital delivery and postpartum care visits, while maternal care knowledge and perceived quality of hospital care did not have direct correlation. For ANC, SES (β= − 0.36, β< 0.01), time from home to the nearest hospital (β= − 0.13, β< 0.05), knowledge on maternal care (β=0.12, β< 0.01) and perceived quality of hospital care (β=0.10, β< 0.01) were all directly correlated factors. Treating ANC as an intermediate variable showed the indirect relationship that perceived quality of hospital care (β=0.01, β< 0.01) and maternal care knowledge (β=0.02, β< 0.01) had with hospital delivery and postpartum care rates.
Conclusions: Use of maternal health services is low among women in ethnic rural areas. ANC has important direct and intermediate effects on subsequent use of hospital delivery and postpartum care. Improving ANC behavior should be a priority of maternal health care reforms. Given the long travel times for these women, reforms must also prioritize breaking down practical barriers that prevent this population from accessing care.

This paper describes the current level of human capital in China and seeks to identify a number of education-related challenges that may slow down the nation’s economy from transitioning to high-income status. Relying on recent census-based data from OECD for the rest of the world and using data from the 2015 Micro-Census for China, the authors show that the low levels of education of China’s labour force is really a problem that has its roots in the past (in the 1970s, 1980s, and 1990s). In recent years (since 2000), China has been investing heavily in education as shown by the increasing the share of youth, including rural youth, attending high school. Despite this recent effort to raise the nation’s human capital, the education system still faces several challenges in trying to provide high-quality education for all youth. First, the government must figure out a way to overcome the relatively low rates of participation in high school by rural students. Second, there is concern that many vocational schools, especially those in rural areas, cannot deliver quality education. Finally, the paper will show that many rural students may be unprepared due to poor early childhood development outcomes.
