Severity of maternal anemia and the risk of giving birth to a small vulnerable newborn: A cohort analysis of the WOMAN‐2 trial in four countries

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To investigate the association between maternal hemoglobin concentration and the risk of birth to a small vulnerable newborn (SVN). Methods We conducted a cohort analysis of women with moderate or severe anemia enrolled in the World Maternal Antifibrinolytic Trial‐2 (WOMAN‐2) across Nigeria, Pakistan, Tanzania, and Zambia (August ...

Risk factors for intrapartum stillbirth and the survival probabilities of fetuses among pregnant women with complications: Secondary analysis of data from a multicenter prospective cohort study in India

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To identify the risk factors for intrapartum stillbirth and examine whether these are different from that of antepartum stillbirth, and investigate the survival probabilities of fetuses by gestational age in high‐risk pregnancies. Methods We conducted a secondary data analysis of a hospital‐based cohort study from India, including ...

Fiscal Policy Regimes in Resource‐Rich Economies

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We analyse fiscal policy in resource‐rich economies using a novel Bayesian regime‐switching panel model. The identified regimes capture pro‐ or countercyclical fiscal behaviour by allowing regime‐specific shifts in the average fiscal stance, while the switches between the regimes have the interpretation of changes in fiscal policy.

Visualize online collocation dictionary with force-directed graph [PDF]

open access: yes, 2012
For second-language learners, collocational knowledge is very important. Knowing collocational phrases allows learners to speak and write in their targeted language naturally and reduce dramatically side effect of their first language.

Sleep patterns during infancy and neurodevelopmental and behavioral outcomes in early childhood: A prospective cohort study

open access: yesJCPP Advances, EarlyView.
Abstract Background Infant sleep is multidimensional, with sleep habits and sleep problems often co‐occurring and changing rapidly during early life. Evidence links infant sleep with later neurodevelopmental and behavioral outcomes, yet few studies have examined overall sleep patterns, their changes over time, and outcomes across multiple preschool ...

Induced Acyclic Tournaments in Random Digraphs: Sharp Concentration, Thresholds and Algorithms

open access: yesDiscussiones Mathematicae Graph Theory, 2014
Given a simple directed graph D = (V,A), let the size of the largest induced acyclic tournament be denoted by mat(D). Let D ∈ D(n, p) (with p = p(n)) be a random instance, obtained by randomly orienting each edge of a random graph drawn from Ϟ(n, 2p). We

Moment Priors for Bayesian Model Choice with Applications to Directed Acyclic Graphs [PDF]

open access: yes
We propose a new method for the objective comparison of two nested models based on non-local priors. More specifically, starting with a default prior under each of the two models, we construct a moment prior under the larger model, and then use the ...

A Min–Max Relation on Dicuts and Dijoins in Weighted Chordal Digraphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT In a digraph, a dicut is a cut where all the arcs cross in one direction. A dijoin is a subset of arcs that intersects every dicut. Edmonds and Giles conjectured that in a weighted digraph, the minimum weight of a dicut is equal to the maximum size of a packing of dijoins. This has been disproved. However, the unweighted version conjectured by
