Parametric hazard rate models for long-term sickness absence [PDF]

open access: yes, 2008
PURPOSE: In research on the time to onset of sickness absence and the duration of sickness absence episodes, Cox proportional hazard models are in common use. However, parametric models are to be preferred when time in itself is considered as independent

Trait plasticity enables trees and shrubs to live as epiphytes throughout the coast redwood canopy

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract The radiation of plants into epiphytic niches has largely been studied by comparing closely related taxa that contain both epiphytic and terrestrial species. While these studies have led to important insights, they leave unanswered an important question—what traits allow for the initial colonization of the epiphytic niche?

Herbivore decline switches a high Arctic plant community from top‐down to bottom‐up control

open access: yesJournal of Ecology, Volume 114, Issue 4, April 2026.
Declining abundance of large herbivores in the Arctic loosens the top‐down control on the vegetation, which now responds primarily to the changing climatic conditions and follows the general greening pattern observed in a warming Arctic. These changes may impact terrestrial ecosystem element cycling, with knock‐on effects on the dynamics in adjacent ...

The Collective Dynamics of Smoking in a Large Social Network [PDF]

open access: yes, 2008
Based on repeated surveys of 12,067 closely interconnected people between 1971 and 2000, examines the extent to which smoking spreads socially and to which groups of smokers quit together, as well as trends in the number and social centrality of ...

Language counts: Early language mediates the relationship between parent education and children\u27s math ability [PDF]

open access: yes, 2018
Children\u27s early math skills have been hailed as a powerful predictor of academic success. Disparities in socioeconomic context, however, also have dramatic consequences on children\u27s learning.

Water Oxygen Isotope Thermometer in Headwaters: Indicating Groundwater Recharge and Peatland Water Dependence on Air Temperature

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Stable isotopes in water act as natural tracers of precipitation temperature. In mountainous environments, the oxygen isotopic signature measured in stream water reflects air temperature during precipitation events. Oxygen‐isotope‐derived temperatures are closely linked to recharge processes, particularly in peatlands, as well as in groundwater systems.

Exploring Raman Spectroscopy as a Detection Tool for Cardiovascular Diseases and Diabetes Mellitus in Fingernails

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 3, Page 503-512, March 2026.
Endogenous constituents vary between fingernails of healthy, cardiovascular and diabetic participants. Raman spectroscopy yields a biochemical fingerprint of key endogenous constituents and disease‐related biomarkers. Combined with machine learning algorithms, Raman spectroscopy can classify healthy, cardiovascular and diabetic based on their Raman ...
