Assessing the effect of an educational intervention on early childhood development among Mexican preschool children in the state of Oaxaca: a study protocol of a cluster randomized stepped-wedge trial

open access: yesTrials, 2022
Background Early childhood development (ECD) is essential in human capacity building and a critical element in the intergenerational process of human development.

Performance of Small Cluster Surveys and the Clustered LQAS Design to estimate Local-level Vaccination Coverage in Mali [PDF]

open access: yes, 2012
Background Estimation of vaccination coverage at the local level is essential to identify communities that may require additional support. Cluster surveys can be used in resource-poor settings, when population figures are inaccurate.

Exploring sex-specific time trends in drinking patterns in the Greenlandic population from 1993 to 2014 – a large Arctic Indigenous population

open access: yesInternational Journal of Circumpolar Health, 2022
A drinking pattern characterised by occasional excessive drinking is a key challenge for public health in Greenland. The objective was to examine sex-specific time trends in drinking patterns among Greenland Inuit.

Population and species neighbor identity impact trait–trait relationships and plant performance

open access: yesPopulation Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

Trends, determinants, and newborn mortality related to thermal care and umbilical cord care practices in South Asia

open access: yesBMC Pediatrics, 2019
Background Although child mortality has decreased over the last several decades, neonatal mortality has declined less substantially. In South Asia, neonatal deaths account for the majority of all under-five deaths, calling for further study on newborn ...

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

open access: yesPopulation Ecology, EarlyView.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

Implementation and validation of a probabilistic linkage method for population databases without identification variables

open access: yesHeliyon, 2022
Linking records of the same person from different sources makes it possible to build administrative cohorts and perform longitudinal analyzes, as an alternative to traditional cohort studies, and have important practical implications in producing ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

The Croatian Adult Health Cohort Study (CroHort) - background, methodology & perspectives [CroHort: Hrvatska kohortna studija kardiovaskularnog zdravlja - pozadina, metodologija i perspektiva] [PDF]

open access: yes, 2012
Health interview surveys are important source of health information. All previous adult population-based health interview surveys in Croatia until CroHort, were one-off projects with very limited possibility of data comparison.

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...
