Information technology is increasingly being utilized in the property market. This paper examines how sensitive house transaction prices are to online price estimates using data collected from Zillow. We find that online property price estimates strongly predict transaction prices even when observable and unobservable house and neighborhood characteristics are controlled for. In addition, we find evidence that suggests that online price estimates may have a direct impact on transaction prices.
Solar lanterns are promoted across rural Sub-Saharan Africa to improve both lighting in homes and educational outcomes. We undertake a randomized controlled trial in Zimba District, Zambia, to evaluate whether solar lanterns help children study more effectively and improve academic performance. Our research design accounts for potential income effects arising from the giveaways of lanterns and also “blinds” participants to the study’s purpose.
Companies' sustainable sourcing practices play an increasing role in addressing the social and environmental challenges in agricultural supply chains. Yet the approaches companies take to regulate their supply chains continue to evolve. I use the chocolate industry as a critical case to explore how and why companies have changed their approaches to sustainable cocoa sourcing over the last 20 years.
Crop responses to climate warming suggest that yields will decrease as growing-season temperatures increase. Deutsch et al. show that this effect may be exacerbated by insect pests (see the Perspective by Riegler). Insects already consume 5 to 20% of major grain crops. The authors' models show that for the three most important grain crops—wheat, rice, and maize—yield lost to insects will increase by 10 to 25% per degree Celsius of warming, hitting hardest in the temperate zone.
The extent to which armed conflicts—events such as civil wars, rebellions, and interstate conflicts—are an important driver of child mortality is unclear. While young children are rarely direct combatants in armed conflict, the violent and destructive nature of such events might harm vulnerable populations residing in conflict-affected areas. A 2017 review estimated that deaths of individuals not involved in combat outnumber deaths of those directly involved in the conflict, often more than five to one.
The overall goal of this study is to examine whether infant feeding practices differ between mothers and grandmothers in rural China. We randomly sampled 1383 caregivers of infants aged 18 to 30 months living in 351 villages across 174 townships in nationally designated poverty counties in rural areas. Results show that ahigh fraction of caregivers of 18- to 30-month-old children living in low-income areas of rural China do not regularly engage in positive infant feeding practices. Only 30% of children in our sample achieved adequate dietary diversity. Only 49% of children in our sample were fed meat in the day prior to survey administration. Few caregivers reported giving any vitamin supplements (such as calcium or iron supplements) to their children. We find that 33% of the children were cared for by grandmothers rather than mothers, and thatgrandmothers feed a less diversified diet to children than do mothers. Most (84%) caregivers rely solely ontheir own experiences, friends, and family members in shaping their feeding behaviors. Overall infant feeding practices are poor in rural China. Grandmothers engage in poorer feeding practices than do mothers. Grandmothers have improved their feeding practices compared to when their own children were young. Our results suggest shortcomings in the quality of infant feeding practices, at least in part due to an absence ofreliable information sources.
Key words: child development, feeding practices, information sources, rural China
Using the Bayley Scales of Infant and Toddler Development III (BSID III), we examine the rates of developmental delays among infants/toddlers aged 0-3 years old in four major subpopulations of rural China, which altogether account for 69% of China’s rural infants/toddlers and 49% of infants/toddlers nationwide. The data demonstrates that 85% of the 3,353 rural infants/toddlers in our sample suffer from at least one kind of developmental delay. Specifically, 49% of the toddlers have cognitive delays; 52% have language delays, 53% have social-emotional delays, and 30% have motor delays.
Political parties in the United States and Britain used clientelism and patronage to govern throughout the nineteenth century. By the twentieth century, however, parties in both countries shifted to programmatic competition. This book argues that capitalists were critical to this shift. Businesses developed new forms of corporate management and capitalist organization, and found clientelism inimical to economic development.
The adjusted mortality for care teams with anesthesiologist assistants was 1.6% (95% CI, 1.4 to 1.8) versus 1.7% for care teams with nurse anesthetists (95% CI, 1.7 to 1.7; difference −0.08; 95% CI, −0.3 to 0.1; P = 0.47). Compared to care teams with nurse anesthetists, care teams with anesthesiologist assistants were associated with non–statistically significant decreases in length of stay (−0.009 days; 95% CI, −0.1 to 0.1; P = 0.89) and medical spending (−$56; 95% CI, −334 to 223; P = 0.70).
The standard of care treatment for maximally resected, high risk (≥ 40 years old or sub-totally resected) low grade glioma (LGG) patients was established by RTOG 9802, which showed an overall survival (OS) of 13.3 years for patients treated with radiotherapy (RT) + PCV (procarbazine, lomustine [CCNU], vincristine) chemotherapy compared to 7.8 years for RT alone. In the era of value-based health care, cost-effectiveness analyses (CEA) have the potential to inform coverage decisions and patient care.
The decreasing effectiveness of antimicrobial agents is a global public health threat, yet risk factors for community-acquired antimicrobial resistance (CA-AMR) in low-income settings have not been clearly elucidated. Our aim was to identify risk factors for CA-AMR with extended-spectrum β-lactamase (ESBL)–producing organisms among urban-dwelling women in India. We collected microbiological and survey data in an observational study of primigravidae women in a public hospital in Hyderabad, India.
Linkages between climate and mental health are often theorized, but remain poorly quantified. In particular, it is unknown whether the rate of suicide, a leading cause of death globally, is systematically affected by climatic conditions. Using comprehensive data from multiple decades for both the United States and Mexico, we find that suicide rates rise 0.7% in US counties and 2.1% in Mexican municipalities for a 1 °C increase in monthly average temperature. This effect is similar in hotter versus cooler regions and has not diminished over time, indicating limited historical adaptation.
Bernard Malamud, Saul Bellow, Philip Roth, and their critics embraced the notion that their work displayed an affinity to Russian and Yiddish literature, especially to the work of Fyodor Dostoevsky, Nikolai Gogol, and Sholem Aleichem. Like these writers, the prominent American Jewish writers of the 1960s were understood as producing writing that emerged from their authentic, often negative emotions, work that voiced complaints.
How does religious nationalism arise? Poland and the Philippines represent two striking examples of religious and national identities becoming practically coterminous. Yet these two Catholic nations traveled different historical paths towards a tight fusion of religion and nation. In Poland, the church defended the nation in dramatic struggles against a strong and secularizing state. This fused religious and national identities, endowing the church with unrivaled moral authority.
Political scientists have found that early life experiences powerfully affect future leaders. Drawing on a variety of sources, this article investigates the formative role of Xi Jinping’s youth during a tumultuous time period in Chinese history. Xi’s life before and during the Cultural Revolution help explain his toughness, idealism, pragmatism, and caution. However, the evidence on how Xi’s childhood and young adulthood shaped his view on how to best handle political contradictions is ambiguous.
Rising atmospheric carbon dioxide concentrations are anticipated to decrease the zinc and iron concentrations of crops. The associated disease burden and optimal mitigation strategies remain unknown. We sought to understand where and to what extent increasing carbon dioxide concentrations may increase the global burden of nutritional deficiencies through changes in crop nutrient concentrations, and the effects of potential mitigation strategies.
In this study published in the American Journal of Managed Care, the authors found that premiums for ACA Marketplace plans were higher in rating areas in which physician, hospital, and insurance markets were less competitive.
Education of poor and disadvantaged populations has been a long-standing challenge for education systems in both developed and developing countries. In China, millions of students in rural areas and migrant communities lag far behind their urban counterparts in terms of academic achievement. When they fall behind, they often have no way to catch up. Many of their parents have neither the skills nor the money to provide remedial tutoring; rural teachers often do not have time to give students the individual attention they need.
