The world bank was set up in 1944. In the aftermath of the second world war, the institution was there to give loans to countries rebuilding after the conflict. Their first loan went to France - but with stipulations about repayment that set a tone for future funds. A new series, authored by Devi Sridhar, and her team from the University of...

With immigration increasingly visible in the news and the political space in the United States and internationally, getting access to accurate, high-quality data is essential to understand immigration’s demographic effects and impacts on the economy, education and labor systems, and communities. This event marks the release of the Immigration Data Matters guide.

At this release of an updated version of the popular Immigration Data Matters guide, presenters discuss how to navigate and access the increasing number of data sources on immigration and immigrants in the United States and internationally. 

This useful online guide links users directly to the most credible, high-quality data on immigrants and immigration in the United States and internationally. The easy-to-use guide includes more than 220 data resources compiled by governmental and nongovernmental sources, covering topics ranging from population stock and flow numbers to statistics on enforcement, public opinion, religious affiliation, and much more.

Researchers suggest the coldest material in the universe could reveal the presence of dark matter particles.

Marking the release of an MPI brief, experts on this webinar examine the key features of English Learner (EL) instructional models and discuss state- and district-level approaches to supporting schools in implementing effective EL program models, with a particular focus on what is being done in New York and Madison Wisconsin.

Abstract:
The conditional independence assumption of the Felligi and Sunter (FS) model in probabilistic record linkage is often violated when matching real-world data. Ignoring conditional dependence has been shown to seriously bias parameter estimates. However, in record linkage, the ultimate goal is to inform the match status of record pairs and therefore, record linkage algorithms should be evaluated in terms of matching accuracy. In the literature, more flexible models have been proposed to relax the conditional independence assumption, but few studies have assessed whether such accommodations improve matching accuracy. In this paper, we show that incorporating the conditional dependence appropriately yields comparable or improved matching accuracy than the FS model using three real-world data linkage examples. Through a simulation study, we further investigate when conditional dependence models provide improved matching accuracy. Our study shows that the FS model is generally robust to the conditional independence assumption and provides comparable matching accuracy as the more complex conditional dependence models. However, when the match prevalence approaches 0% or 100% and conditional dependence exists in the dominating class, it is necessary to address conditional dependence as the FS model produces suboptimal matching accuracy. The need to address conditional dependence becomes less important when highly discriminating fields are used. Our simulation study also shows that conditional dependence models with misspecified dependence structure could produce less accurate record matching than the FS model and therefore we caution against the blind use of conditional dependence models.

In some countries, mountains are considered deities. In others, mountains are peaks to climb. In others still, mountains, like volcanoes, are spirits that can be angered. In countries around the world though, mountains provide life-sustaining water, energy and food for over half the world’s population.

Growing crops, fishing, harvesting fruits and nuts from the forests are just some examples of the activities that millions of people do daily to get food to eat or to earn a living. But when their rights to that land or those natural resources aren’t recognized, livelihoods and food sources can disappear from one day to the next.

Keeping preschool class sizes at or under 20 children, and keeping child-teacher ratios at 10 to 1, will work for most children in preschool, according to a new study.

Class size does matter for teachers and students, but only if the instruction used in the small class size is different from those instructional practices used in a large one.

The situation in the Clark County School District is a perfect storm that serves as a reminder of how difficult it is for school officials to plan for changing conditions

While independent schools can feel quite different from their public, charter, and parochial counterparts, the glue that holds all schools together is this noble charge we call teaching.

While teaching is still in the top 10 of highly regarded professions, parents have stopped encouraging their children to become teachers. Guest blogger Heather Harding explores what should be done.

Being a school leader is difficult. They are meant to focus on improvement while also negotiating their way through adult behavior. Can leadership coaching help them focus on what truly matters?

Gareth Polhill, Bruce Edmonds, Petra Ahrweiler, Patrycja Antosz, Geeske Scholz, Émile Chappin, Melania Borit, Harko Verhagen, Francesca Giardini and Nigel Gilbert: The COVID-19 pandemic is causing a dramatic loss of lives worldwide, challenging the sustainability of our health care systems, threatening economic meltdown, and putting pressure on the mental health of individuals (due to social distancing and lock-down measures). The pandemic is also posing severe challenges to the scientific community, with scholars under pressure to respond to policymakers’ demands for advice despite the absence of adequate, trusted data. Understanding the pandemic requires fine-grained data representing specific local conditions and the social reactions of individuals. While experts have built simulation models to estimate disease trajectories that may be enough to guide decision-makers to formulate policy measures to limit the epidemic, they do not cover the full behavioural and social complexity of societies under pandemic crisis. Modelling that has such a large potential impact upon people’s lives is a great responsibility. This paper calls on the scientific community to improve the transparency, access, and rigour of their models. It also calls on stakeholders to improve the rapidity with which data from trusted sources are released to the community (in a fully responsible manner). Responding to the pandemic is a stress test of our collaborative capacity and the social/economic value of research.
