Exercise promotes pulsatile shear stress in the arterial circulation and ameliorates cardiometabolic diseases. However, exercise-mediated metabolic transducers for vascular protection remain under-investigated. Untargeted metabolomic analysis demonstrated that wild-type mice undergoing voluntary wheel running exercise expressed increased endothelial stearoyl-CoA desaturase 1 (SCD1) catalyzes anti-inflammatory lipid metabolites, namely, oleic (OA) palmitoleic acids (PA), to mitigate...
Despite being the poorest or second participant, Vietnam outperformed all other developing countries, and many wealthier on 2012, 2015, 2018 PISA assessments. We investigate Vietnam's strong performance, evaluating several possible explanations for this apparent exemplary achievement. After correcting potentially non-representative samples, including bias from large out-of-school population, remains a positive outlier conditional its income. Possible higher motivation of, coaching given to,...
BACKGROUND: Exercise augments hemodynamic shear to activate mechano-sensitive molecular transducers in the vascular endothelium. Recently, central nervous system has been reported mediate neuroimmune interaction aortic adventitia (AA). Whether exercise modulates sympathetic nerve with immune cells mitigate stiffness remains unknown. METHODS AND RESULTS: Four weeks of Ang II (angiotensin II) infusion C57BL/6 mice increased neural activation increase expression TH (tyrosine hydroxylase) for...
Despite a sizable literature on the labor market effects of maternity leave regulation women in developed countries, how these policies affect women's work developing countries with large informal sector remains poorly understood. This study examines extending requirement affects decision to or formal Vietnam. We use difference-in-differences approach evaluate 2012 Amendments Vietnam Labor Law, which imposes longer than before. find that law increases employment and decreases unpaid among...
In Vietnam, all lands belong to the state, which assigns usufruct rights those individuals and households. 1993, state gave 20-year growers of annual crops, 50-year perennial crops. 2013, as crops were about expire, Vietnamese government passed a law—the Land Law 2013—that extended landowners by 50 years. We exploit this largely unanticipated shock study effect tenurial security on agricultural investment. Using difference-in-differences design, we find that 2013 is associated with higher...
Since the summer of 2020, rate coronavirus cases in United States has been higher rural areas than urban areas, raising concerns that patients with disease 2019 (COVID-19) will overwhelm under-resourced hospitals. Using data from University Minnesota COVID-19 Hospitalization Tracking Project and U.S. Department Health Human Services, we document disparities hospitalization rates between areas. We show rural-urban differences admission were minimal 2020 but began to diverge fall 2020. Rural...
We investigate the effect of Risk Corridors (RC) program on premiums and insurer participation in Affordable Care Act (ACA)’s Health Insurance Marketplaces. The RC program, which was defunded ahead coverage year 2016, ended 2017, is a risk sharing mechanism: it makes payments to insurers whose costs are high relative their revenue, collects from relatively low. show theoretically that creates strong incentives lower for some insurers. Empirically, we find who claimed 2015, before defunding,...
Many insurance markets have reinstated premium stabilization programs to ensure financial protection from market volatility. In this paper, we focus on one such regulation-risk corridors (RCs)-in the context of Health Insurance Marketplaces established under Affordable Care Act. We develop a model show how program provided incentives for some insurers lower their premiums. The RCs was defunded unexpectedly coverage year 2016, before its legislated end in 2016. Consistent with model, find...
Despite being the poorest or second participant, Vietnam performed much better than all other developing countries, and even ahead of wealthier countries such as U.S. U.K., on 2012 2015 PISA assessments. We provide a rigorous investigation Vietnam's strong performance. After making various parametric non-parametric corrections for potentially non-representative samples, including bias due to large out-of-school population, still remains positive outlier conditional its income. Possible...

Large artery stiffness is a significant risk factor for cardiovascular diseases. Our previous study suggested that angiotensin II (Ang II) stimulates sympathetic innervation in aortic adventitia (AA) leading to elevated mean arterial blood pressure and increased fibrosis, while voluntary wheel-running (VWR) reduces them. The aim of this explore mechanism under Ang II-induced the remodeling through nerves immune cell interactions using transcriptomics. We isolated cells AA from (1.5...
We study how Vietnam's Escuela Nueva, a pedagogical reform that promotes participatory and collaborative learning in primary schools, affects students' behaviors short long run. Using propensity score matching approach, we find the model increases likelihood of giving receiving feedback from peers as well asking questions class. The peer-learning effects appear to persist run students enter lower secondary school. Qualitative interviews with teachers school principals also provide evidence...
Since the late 20th century, globalisation has become an irresistible trend, bringing opportunities and challenges for Vietnam’s economic development. After 1986 reforms, Vietnamese coffee production increased more than 200-fold, country became second-largest producer in world. is a unique story history of global industry. This study examines development Lam Dong province Vietnam. vital area It describes how smallholder farmers are responding to effects crisis, including issues such as...
This study examines the long-term effects of a national policy Vietnam that provided free public health care for all children under 6 years old, 74.2% whom were previously uninsured. I estimate exposure to at age 0 on outcomes 7 21, when individuals are no longer eligible policy. Using difference-in-differences design, identify from cross-cohort variation in eligibility and cross-province policy’s intensity.I find early-age leads lower later-life hospitalization out-of-pocket expenditures...
This paper evaluates how Vietnam's Escuela Nueva (VNEN) program, an educational reform for primary schools supported by the World Bank, affected cognitive (mathematics and Vietnamese) non-cognitive (socioemotional) skills of students in that country. We use propensity score matching to estimate both short-term (1-3 years) long-term (5-7 average treatment effects on treated (ATT). find impacts VNEN students' are relatively small short-term, they larger boys, ethnic minorities, Northern...
The economic growth of Vietnam in the 1990s has been a popular topic among economists because there are many aspects it subjected to development studies. This paper attempts explore one these aspects, income mobility economy, during period 2004-2008 by estimating expenditure mobility, using Household Living Standard Survey (VHLSS) data. is done applying methodology that Heise (1969) developed his work on test-retest correlations, reduce classical upward bias due measurement errors.
