Empirical researchers frequently use dynamic panel data models and employ Generalized Method of Moments (GMM) estimators (Hansen, 1982) to estimate model parameters. An important practical problem in the estimation of a dynamic panel data model is the choice of moments as it provides a large number of moment conditions. Even though adding moment conditions(More)
Tellurium tetrachloride (TeCl(4)) and diphenyl ditelluride (DPDT) cytotoxicity, was investigated in rat astrocytes. Concentrations of 0.24-250μM (24h) were tested for viability using MTT(3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) and trypan blue exclusion. MTT showed significant decreases at all concentrations tested for both compounds.(More)
I develop a model of competition between charter schools and traditional public schools and estimate the model using administrative data from North Carolina. I use the model to quantify how existing charter schools have affected test scores for both charter and public school students and simulate charter school entry and student test scores were binding(More)
Programmed death-1 receptor (PD-1) expressed in many immune cells is known to trigger T-cell exhaustion but the significance of macrophage-associated PD-1 in relevance to macrophage apoptosis is not known. This study is aimed to delineate whether PD-1 pathway has any role in eliciting macrophage apoptosis and, if so, then how the intra-macrophage parasite,(More)
ABOUT THE TOOLKIT Over the past decade, donor organizations, researchers, and development practitioners have recognized the importance of collecting mixed methods gender and assets data using mixed methods in monitoring & evaluation and impact evaluation of development programs. Nonetheless, many researchers and practitioners remain unsure of why or how to(More)
This paper was developed for the UN Foundation and ExxonMobil Foundation research collaboration on “Building a Roadmap for Women’s Economic Empowerment,” building on ongoing work in the Gender, Agriculture, and Assets Project (GAAP), supported by the Bill and Melinda Gates Foundation. We would like to thank Mayra Buvinic and Emily Courey Pryor for their(More)
OBJECTIVE To examine the impact on infant and young child nutrition knowledge and practice of mothers who were neighbors of mothers participating in a nutrition Behavior Change Communication (BCC) intervention in rural Bangladesh. METHODS We analyzed data from 300 mothers whose neighbor participated in a nutrition BCC intervention and 600 mothers whose(More)
Behaviour change communication (BCC) can improve infant and young child nutrition (IYCN) knowledge, practices, and health outcomes. However, few studies have examined whether the improved knowledge persists after BCC activities end. This paper assesses the effect of nutrition sensitive social protection interventions on IYCN knowledge in rural Bangladesh,(More)
Twenty-one states are increasing the requirements for a high school diploma so that all students graduate college-ready. The new graduation requirements include completion of Algebra, Geometry and Algebra II. Before this recent set of reforms, states had graduation requirements related to the number of math credits, irrespective of math course content. To(More)
