Deaths from undetected COVID-19 infections as a fraction of COVID-19 deaths can be used for early detection of an upcoming epidemic wave

Plos.org 

by Yashaswini Mandayam Rangayyan, Sriram Kidambi, Mohan Raghavan

With countries across the world facing repeated epidemic waves, it becomes critical to monitor, mitigate and prevent subsequent waves. Common indicators like active case numbers may not be sensitive enough in the presence of systemic inefficiencies like insufficient testing or contact tracing. Test positivity rates are sensitive to testing strategies and cannot estimate the extent of undetected cases. Reproductive numbers estimated... Читать дальше...

Study of Bayesian variable selection method on mixed linear regression models

Plos.org 

by Yong Li, Hefei Liu, Rubing Li

Variable selection has always been an important issue in statistics. When a linear regression model is used to fit data, selecting appropriate explanatory variables that strongly impact the response variables has a significant effect on the model prediction accuracy and interpretation effect. redThis study introduces the Bayesian adaptive group Lasso method to solve the variable selection problem under a mixed linear regression model with a hidden state and...

The impact of hyperglycemia upon BeWo trophoblast cell metabolic function: A multi-OMICS and functional metabolic analysis

Plos.org 

by Zachary J. W. Easton, Xian Luo, Liang Li, Timothy R. H. Regnault

Pre-existing and gestationally-developed diabetes mellitus have been linked with impairments in placental villous trophoblast cell metabolic function, that are thought to underlie the development of metabolic diseases early in the lives of the exposed offspring. Previous research using placental cell lines and ex vivo trophoblast preparations have highlighted hyperglycemia is an important independent regulator of placental function. Читать дальше...

The importance of oxytocin neurons in the supraoptic nucleus for breastfeeding in mice

Plos.org 

by Mitsue Hagihara, Kazunari Miyamichi, Kengo Inada

The hormone oxytocin, secreted from oxytocin neurons in the paraventricular (PVH) and supraoptic (SO) hypothalamic nuclei, promotes parturition, milk ejection, and maternal caregiving behaviors. Previous experiments with whole-body oxytocin knockout mice showed that milk ejection was the unequivocal function of oxytocin, whereas parturition and maternal behaviors were less dependent on oxytocin. Whole-body knockout, however, could induce... Читать дальше...



Do political incentives promote or inhibit corporate social responsibility? The role of local officials’ tenure

Plos.org 

by Yunyu Wu

The existing literature on corporate social responsibility (CSR) drivers focuses on firm- and institution-level factors and rarely on the role of political incentives. Public officials control enormous resources in China, and their political incentives substantially shape certain firm behaviors. As CSR is one of the critical measures that the central government uses to evaluate the performance of local government, local officials have the incentive to channel firms into accomplishing their political goals.

Statistical injury prediction for professional sumo wrestlers: Modeling and perspectives

Plos.org 

by Shuhei Ota, Mitsuhiro Kimura

In sumo wrestling, a traditional sport in Japan, many wrestlers suffer from injuries through bouts. In 2019, an average of 5.2 out of 42 wrestlers in the top division of professional sumo wrestling were absent in each grand sumo tournament due to injury. As the number of injury occurrences increases, professional sumo wrestling becomes less interesting for sumo fans, requiring systems to prevent future occurrences. Statistical injury prediction is a useful... Читать дальше...

Exploring the associations between the perception of water scarcity and support for alternative potable water sources

Plos.org 

by Christina Semasinghe, Santosh Jatrana, Tanya J. King

This study examines the association between the perception of water scarcity and support for alternative water sources in general, and specifically desalination and recycled water. It also examines the mediating role that perception of climate change has on the aforementioned association. A 46-item survey (n = 588) was conducted in the Geelong region of Australia. Logistic regression was used to determine the independent association... Читать дальше...
