Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background Cerebrospinal fluid (CSF) serves as a medium for nutrient delivery and waste clearance. The T1 relaxation rate, R1, can be used to measure the concentration of intrinsic solutes and extrinsic contrast agents. Purpose To implement a method for R1 mapping and segmentation of CSF and to use this method to explore how R1 of CSF relates ...

Journal of Organizational Behavior, EarlyView.ABSTRACT Although objectification is prevalent in leadership relations, little is known about (a) why some supervisors objectify their employees to a greater extent than others and (b) when and how such objectification manifests in a supervisor's leadership behavior.

Pitman efficiency lower bounds for multivariate distribution-free tests based on optimal transport
Journal of the Royal Statistical Society Series B: Statistical MethodologyAbstract The Wilcoxon rank sum test is one of the most popular distribution-free two-sample tests for univariate data. Among the important reasons for their popularity are the striking results of Hodges–Lehmann and Chernoff–Savage, where the authors show that the asymptotic (Pitman) relative efficiency of Wilcoxon’s test compared to ...

Spatial and temporal variation in survival of female wild turkeys
The Journal of Wildlife Management, EarlyView.We monitored 370 female wild turkeys across North Carolina's 3 ecoregions from 2020‐2022 to understand factors influencing their survival. Female survival varied by ecoregion and behavior state, with the incubation period having the lowest survival rates. None of the land cover variables affected survival.

On the Pitman Efficiency of One-sided Kolmogorov and Smirnov Tests for Normal Alternatives
The Annals of Mathematical Statistics, 1966 1. Summary. Lower bounds for the Pitman efficiency of the one-sided Kolmogorov test for all normal alternatives and for the Smirnov test for normal shift alternatives are obtained. In the one-sample case this does not fall below 36 per cent at the usual levels of significance and power. In the two-sample case the lower bound depends on the ratio of the

Colouring and breaking sticks: random distributions and heterogeneous clustering [PDF]
, 2010 We begin by reviewing some probabilistic results about the Dirichlet Process and its close relatives, focussing on their implications for statistical modelling and analysis.

Smoothed nonparametric two-sample tests
, 2017 We propose new smoothed median and the Wilcoxon's rank sum test. As is pointed out by Maesono et al.(2016), some nonparametric discrete tests have a problem with their significance probability. Because of this problem, the selection of the median and the

Knowledge and Process Management, EarlyView.ABSTRACT This study explores how healthcare organisations translate satisfaction survey feedback into organisational knowledge to support organisational learning and knowledge‐based improvement. Hospitals widely use satisfaction surveys to gather feedback from healthcare professionals; however, limited research explains how feedback processes become ...

Environmental influence on intraspecific trait variation in the tropical seagrass Halodule uninervis
Oikos, EarlyView.Intraspecific trait variation (ITV) enhances the precision of applying functional trait approaches in plant ecology. Despite its benefits, ITV is rarely considered in functional trait‐based seagrass research. The goal of our research is to measure ITV in the tropical seagrass species Halodule uninervis and assess the environmental factors associated ...
