Impacts of the Preschool Safe Program on Marginalized Girls in Northern Nigeria

open access: yesChild Development, Volume 96, Issue 3, Page 1128-1147, May/June 2025.
ABSTRACT Quality early childhood education (ECE) can improve children's learning and development in low‐ and middle‐income countries, but little evidence exists of programs targeting marginalized girls in vulnerable rural communities. This study used a matched‐pair mixed‐methods community‐randomized trial to evaluate a preschool program for ...

Spin Correlations in Top Quark Production and the Top Quark Mass [PDF]

open access: yesarXiv, 1996
Top-antitop quark pairs produced at the Tevatron have a sizeable spin correlation. That correlation feeds into the angular distribution of the decay products, particularly in the dilepton channel. Including the expected correlation in an overall analysis of a handful of actual dilepton events continues to favor a lower top mass (centered on 155 GeV ...

Child Vocabulary and Developmental Growth in Executive Functions During Toddlerhood

open access: yesDevelopmental Science, Volume 28, Issue 3, May 2025.
ABSTRACT Executive functions (EFs) emerge in the first years of life and are essential for many areas of child development. However, intraindividual developmental trajectories of EF during toddlerhood and their associations with ongoing development of language skills remain poorly understood. The present three‐wave study examined these trajectories and

Maternal Demographic Patterns in Medication use During Pregnancy: A Nationwide Register Study

open access: yesBasic &Clinical Pharmacology &Toxicology, Volume 136, Issue 4, April 2025.
ABSTRACT In recent years, medication use during pregnancy has increased, yet its association with maternal characteristics remains unclear. To address this gap, we aimed to investigate how maternal age, pre‐gestational body mass index (BMI), smoking, parity, ethnic origin and employment status relate to medication use during pregnancy.

Modelling exchange rate volatility in turbulent periods: The role of oil prices in Nigeria

open access: yesScientific African, 2023
The oil price has been increasingly identified as a key fundamental in the dynamics of exchange rates. As a result, we investigate how changes in oil prices affect the dynamics of exchange rates during crisis periods.

Diagonal Peg Solitaire [PDF]

open access: yesINTEGERS: Electronic Journal of Combinatorial Number Theory 7 (2007) #G01, 2006
We study the classical game of peg solitaire when diagonal jumps are allowed. We prove that on many boards, one can begin from a full board with one peg missing, and finish with one peg anywhere on the board. We then consider the problem of finding solutions that minimize the number of moves (where a move is one or more jumps by the same peg), and find

The genetic consequences of successful reintroduction of wild turkey (Meleagris gallopavo) in Nebraska

open access: yesWildlife Society Bulletin, Volume 49, Issue 1, March 2025.
Wild turkeys were nearly extirpated from much of their range, but populations have been successfully restored owing to reintroductions and effective management. Although early taxonomists described five subspecies, their evolutionary relationships have been unclear.

The shortest game of Chinese Checkers and related problems [PDF]

open access: yesINTEGERS: Electronic Journal of Combinatorial Number Theory 9 (2009) #G01, 2008
In 1979, David Fabian found a complete game of two-person Chinese Checkers in 30 moves (15 by each player) [Martin Gardner, Penrose Tiles to Trapdoor Ciphers, MAA, 1997]. This solution requires that the two players cooperate to generate a win as quickly as possible for one of them. We show, using computational search techniques, that no shorter game is
