Juventud in revolt? Linked fate, political attitudes, and presidential candidate preferences of young Latinos in the 2024 election

open access: yesAnalyses of Social Issues and Public Policy, Volume 26, Issue 1, April 2026.
Abstract Latinos have moved politically right in the last few years in United States elections, with the percentage of Latinos supporting the Republican presidential candidate at an all‐time high in the 2024 elections. The purpose of this study is to better understand this shift, particularly as it relates to the social psychology of identity in ...

frailtypack : An R Package for the Analysis of Correlated Survival Data with Frailty Models Using Penalized Likelihood Estimation or Parametrical Estimation

open access: yesJournal of Statistical Software, 2012
Frailty models are very useful for analysing correlated survival data, when observations are clustered into groups or for recurrent events. The aim of this article is to present the new version of anR package called frailtypack.

S-estimation for penalized regression splines

open access: yes, 2008
This paper is about S-estimation for penalized regression splines. Penalized regression splines are one of the currently most used methods for smoothing noisy data. The estimation method used for fitting such a penalized regression spline model is mostly based on least squares methods, which are known to be sensitive to outlying observations.

Growth Standards for Children With Smith–Magenis Syndrome (SMS)

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 3, Page 569-578, March 2026.
ABSTRACT Smith–Magenis syndrome (SMS, OMIM 182290) is a complex syndromic diagnosis marked by neurobehavioral differences and distinct facial dysmorphisms, caused by haploinsufficiency of the retinoic acid‐1 (RAI1) gene either by a pathogenic sequence variant or deletion at chromosome 17p11.2 involving a portion or all of this gene.

Analysis of Turbulent Modeling for Free‐Surface Flows Using a Hybrid RANS‐LES Model and Particle‐Based Moving Particle Semi‐Implicit Method

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.
A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

Joint Modeling of Birth Outcomes Using a Copula Distributional Regression Approach

open access: yesHealth Economics, Volume 35, Issue 3, Page 399-408, March 2026.
ABSTRACT Low birth weight and preterm birth are key indicators of neonatal health, influencing both immediate and long‐term infant outcomes. While low birth weight may reflect fetal growth restrictions, preterm birth captures disruptions in gestational development. Ignoring the potential interdependence between these variables may lead to an incomplete

Stagewise Boosting Distributional Regression

open access: yesStat, Volume 15, Issue 1, March 2026.
ABSTRACT Distributional regression extends generalized additive models by linking all distributional parameters to covariates. Gradient boosting is among the most effective estimation techniques for such models, yet it can suffer from vanishing gradients, resulting in unstable updates and weak variable selection.

Germination of Dracophyllum sayeri F.Muell. (Ericaceae), a vulnerable montane cloud forest endemic

open access: yesPlant Species Biology, Volume 41, Issue 2, March 2026.
Climate change in tropical montane cloud forest (TMCF) is predicted to impact species adapted to consistent, mild temperatures. We used a temperature gradient plate to investigate the effect of temperature on germination and early seedling survival of Dracophyllum sayeri (Ericaceae), a tree species endemic to TMCF in northeast Queensland, Australia ...

Market Insurance and Risk Pooling in U.S. Crop Insurance

open access: yesAgricultural Economics, Volume 57, Issue 2, March 2026.
ABSTRACT A common assumption is that multiple‐peril crop insurance markets suffer from market failures, thus justifying government intervention in the form of premium subsidies, operating allowances, and reinsurance agreements. One prominent rationale for intervention involves geographic correlation in agricultural production which leads to systemic ...
