Suspected Russian Actors Leverage Alternative Tech Platforms in Continued Effort to Covertly Influence Right-Wing U.S. Audiences

Projecting the ultimate outcome of the war is challenging. However, some major ramifications for Russia and its relations with Ukraine, Europe, and the United States have come into focus.

In Science magazine, Stanford researchers Megan Palmer and David Relman are among co-authors recommending a reset of U.S. and global policy to address the gaps and challenges of current guidance.

After nearly two decades of rising wages for those in the unskilled sectors of China's economy, in the mid-2010s employment and wages in China began to experience new polarizing trends. Using data from the National Bureau of Statistics of China, this paper examines trends in multiple sectors and subeconomies of China, revealing the substantial rise of employment in informal, low-skilled services as well as the steady decline of wage growth in the informal subeconomy. At the same time, we find that although employment growth in the formal subeconomy is relatively moderate, wage growth in high-skilled services is steadily rising. These two trends pose a challenge for China, presenting a new and uncertain period of economic change.

Negotiations could well become necessary at some point. However, the questions of if - and when - to engage should rest with the Ukranian government

Background

The WHO recommends daily use of micronutrient powder for infants and toddlers at risk of micronutrient deficiencies in low-and-middle-income countries. China has established a micronutrient powder distribution program in many rural townships and villages, yet adherence to micronutrient powder remains suboptimal; a little is known about the behavioral inputs that may influence adherence. This study examines direct and indirect behavioral inputs in micronutrient powder adherence among caregivers in rural western China following the Integrated Behavioral Model (IBM) framework.

Methods

Cross-sectional data were collected from April to May 2019 among 958 caregivers of children aged 6 to 24 months in six counties. Data were collected on micronutrient powder adherence behavior, direct behavioral inputs (knowledge and skills, intention, salience, environmental constraints, and habits), and indirect behavioral inputs (attitudes, perceived social norms, and personal agency). Structural equation modeling (SEM) adjusted for sociodemographic covariates was used to evaluate the IBM framework.

Results

Mean micronutrient powder adherence in the previous seven days was 53.02%, and only 22.86% of caregivers consistently fed micronutrient powder from the start of micronutrient powder distribution at six months of age. The SEM model revealed small- to medium-sized effects of salience (β = 0.440, P < 0.001), intention (β = 0.374, P < 0.001), knowledge and skills (β = 0.214, P < 0.001), personal agency (st. effect = 0.172, P < 0.001), environmental constraints (β=-0.142, P < 0.001), and caregiver generation (β = 0.119, P < 0.05) on micronutrient powder adherence. Overall, 54.7% of the variance in micronutrient powder adherence was explained by the IBM framework. Salience had the largest impact on micronutrient powder adherence (Cohen’s f 2 = 0.227). Compared to parent caregivers, grandparents had a higher degree of micronutrient powder adherence on average (P < 0.001), and behavioral inputs were consistent among both parent and grandparent caregivers.

Conclusion

There is a need to improve micronutrient powder adherence among rural caregivers. The IBM framework showed a high degree of explanatory power in predicting micronutrient powder adherence behavior. The findings suggest that increased reminders from doctors regarding micronutrient powder and coaching to improve personal agency in micronutrient powder feeding may increase adherence.

Despite major advancements in China’s K-12 educational outcomes over the past several decades, large regional inequities in academic achievement still exist, a proximal cause of which are gaps in teaching quality. Although conventional approaches to improving teaching quality for disadvantaged populations have overall been unsuccessful in China (i.e., student relocation to better-resourced urban schools, attracting high-quality teachers to low-resource rural schools, and rural teacher training), technology-assisted instruction may play a role in bridging these gaps. This paper explores why conventional approaches to improving teaching have not been effective in rural China and then describes the potential applications of technology-assisted instruction based on the small but growing body of empirical literature evaluating such interventions in other low- and middle-income countries. The paper concludes that while other (non-tech) interventions have thus far been ineffective at raising teaching quality, China may be uniquely positioned to harness technology-assisted instruction due to a favorable ecosystem for the scaling of EdTech in rural areas, though much more experimental research is necessary to assess which approaches and technologies are most cost-effective and how to best scale them.

Abstract

This paper analyzes the impact of paid family leave (PFL) policies in California, New Jersey, and New York on the labor market and mental health outcomes of individuals whose spouses or children experience health shocks. We use data from the 1996-2019 restricted-use version of the Medical Expenditure Panel Survey (MEPS), which provides state of residence and the precise timing of hospitalizations and surgeries, our health shock measures. We use difference-in-difference and event-study models to compare the differences in post-health-shock labor market and mental health outcomes between spouses and parents before and after PFL implementation relative to analogous differences in states with no change in PFL access. We find that PFL access leads to a 7.0 percentage point decline in the likelihood that the (healthy) wives of individuals with medical conditions or limitations who experience a hospitalization or surgery report “leaving a job to care for home or family” in the post-health-shock rounds. Impacts of PFL access on women's mental health outcomes and on men whose spouses have health shocks are more mixed, and we find no effects on parents of children with health shocks. Lastly, we show that improvements in job continuity are concentrated among caregivers with 12 or fewer years of education, suggesting that government-provided PFL might reduce disparities in leave access.

During the first year of the pandemic, East Asian countries have reported fewer infections, hospitalizations, and deaths from COVID-19 disease than most countries in Europe and the Americas. Our goal in this paper is to generate and evaluate hypothesis that may explain this striking fact. We consider five possible explanations: (1) population age structure (younger people tend to have less severe COVID-19 disease upon infection than older people); (2) the early adoption of lockdown strategies to control disease spread; (3) genetic differences between East Asian population and European and American populations that confer protection against COVID-19 disease; (4) seasonal and climactic contributors to COVID-19 spread; and (5) immunological differences between East Asian countries and the rest of the world. The evidence suggests that the first four hypotheses are unlikely to be important in explaining East Asian COVID-19 exceptionalism. Lockdowns, in particular, fail as an explanation because East Asian countries experienced similarly good infection outcomes despite vast differences in lockdown policies adopted by different countries to control the COVID-19 epidemic. The evidence to date is consistent with our fifth hypothesis – pre-existing immunity unique to East Asia – but there are still essential parts of this story left for scientists to check.

This paper estimates the labor market impacts of parenthood in China. We find that becoming a mother has negative impacts on women's labor outcomes. But the impacts appear to recover sooner than what has been found in other countries. A decomposition exercise suggests that parenthood plays a limited role in explaining the large gender inequality in China's labor market. We document a form of intergenerational arrangement that is prevalent among Chinese families: Upon the arrival of a child, grandmothers substantially reduce market labor supply and provide much of the childcare. Grandparents’ help with childcare likely plays an important role in alleviating the motherhood effect. Suggestive evidence indicates that in return, grandparents who help with childcare receive more intra-family transfers and report higher subjective wellbeing. We further show that the motherhood effect, though relatively small, has increased substantially over the past decades. The rising gender gap in the labor market, the declining state sector that historically provides more flexible accommodations for working mothers, and the abolishment of the one-child policy all suggest a rising burden of motherhood on labor market outcomes.

Throughout the COVID-19 pandemic, the United States and Russian Federation have been working quietly to ensure that implementation of the New Strategic Arms Reduction Treaty (New START) remains on track.

Importance  Statin-associated muscle symptoms (SAMS) are common and may lead to discontinuation of indicated statin therapy. Observational studies suggest that vitamin D therapy is associated with reduced statin intolerance, but no randomized studies have been reported.

Objective  To test whether vitamin D supplementation was associated with prevention of SAMS and a reduction of statin discontinuation.

How states join coalitions affects the extent to which they are perceived as blameworthy – or praiseworthy – for the outcome of that coalition.

Family-level factors that characterize the home environment are critical inputs to early language and cognitive development, and potential mechanisms for improving developmental outcomes in vulnerable populations. Many studies conducted in high-income and Western settings highlight stimulating parenting, the home language environment, and parental self-efficacy as possible mechanisms of early development, though less is known about how these family-level factors impact child development in low- or middle-income settings. Even less is known about these family-level factors and early childhood development in rural China, where rates of cognitive and language delay in children aged 0–3 years are as high as 45% and 46%, respectively. Using data collected from 77 rural households with children aged 18–24 months in Southwestern China, this study examines the associations between stimulating parenting, the home language environment, and parental self-efficacy, and early cognitive and language development. The results indicate that stimulating parenting was significantly associated with cognitive, language, and overall development; the home language environment was only significantly associated with language development; and parental self-efficacy was not significantly associated with any developmental outcomes. The implications of such findings reveal mechanisms for supporting healthy child development in rural China.

As digital devices like computers become more widely available in developing countries, there is a growing need to understand how the time that adolescents spend using these devices for recreational purposes such as playing video games is linked with their mental health outcomes. We measured the amount of time that adolescents in rural China spent playing video games and the association of video game time with their mental health. We collected data from primary and junior high schools in a poor, rural province in northwest China (n = 1603 students) and used the Depression, Anxiety, and Stress Scales (DASS-21) to measure mental health symptoms. The results indicated that the average video game time was about 0.69 h per week. There was a significant association between adolescent video game time and poorer mental health. Each additional hour of playing video games also increased the chance of having moderate or above symptoms. Moreover, boys and non-left-behind children had worse mental health if they played more video games. Our study contributes to literature on the links between recreational screen time and mental health, and it sheds light on an issue addressed by recent government legislation to limit the video game time of minors in China.
