Abstract Windshield glasses of Maruti Alto 800 (A800), Hyundai i20 (H20), and Suzuki Eeco (SE) are taken from an automotive repair shop for investigating their physical, optical, mechanical properties to check durability. These amorphous, which is confirmed by X-ray diffraction (XRD). Energy dispersive spectroscopy confirms that the windshield contain SiO 2 , Na O, MgO, CaO, Al O 3 K in variabl...

Objectives: To deal with the Covid-19 pandemic and its unpredictable variations, universities must develop many different response scenarios in which online teaching is considered a suitable, strategic, long-term solution. Our study aims to investigate determine relationships between digital transformation, satisfaction, word-of-mouth communication, students' intention continue learning univers...

Peers, Neighborhoods and Immigrant Student Achievement: Evidence from a Placement Policy Immigrants typically perform worse than other students in the OECD countries. We examine to what extent this is due to the population characteristics of the neighborhoods that immigrants grow up in. We address this issue using a governmental refugee placement policy which provides exogenous variation in the...

Does Education Matter for Economic Growth? Empirical growth regressions typically include mean years of schooling as a proxy for human capital. However, empirical research often finds that the sign and significance of schooling depends on the sample of observations or the specification of the model. We use a nonparametric local-linear regression estimator and a nonparametric variable relevance ...

How Large an Effect Can We Expect from School Reforms? Judging the success of school reform requires an interpretative context in which to judge whether effects obtained are large enough to be important or so small as to be a disappointment. The logic of school reform suggests two frameworks with which to judge the importance of effects. One is the size of the existing achievement gaps between ...

We consider the priority-based allocation problem: there is a set of indivisible objects with multiple supplies (e.g., schools with seats) and a set of agents (e.g., students) with priorities over objects (e.g., proximity of residence area). We study two well-known and competing mechanisms. The agentoptimal stable mechanism (AOSM) allots objects via the deferred acceptance algorithm. The top tr...

In a paper in the POSTGRADUATE MEDICAL JOURNAL we reported four cases of ' simple' ulcer in the colon. The following two examples are now presented as a sequel to this: Case i.-M.C., female, aged 14 years. This child presented with a history of two weeks' intermittent central abdominal pain; the pain was colicky, but not severe enough to incapacitate her. Two days before admission to hospital t...

We explore the hypothesis that demographic changes started in the seventeenth and eighteenth centuries are at the root of the acceleration in growth rates at the dawn of the modern age. During this period, life tables for Geneva and Venice show a decline in adult mortality; French marriage registers show an important increase in literacy; historians measure an acceleration of economic growth. W...
