We conducted a 5-arm randomized controlled trial, assigning participants to one o...
The northern spearnose poacher, Agonopsis vulsa, is a benthic, heavily armored fish that swims primarily using pectoral fins. High-speed kinematics, whole-body lift measurements, and flow visualization were used to study how A. vulsa overcomes substantial negative buoyancy while generating forward thrust. Kinematics for five freely swimming poachers indicate that individuals tend to swim near t...
UNLABELLED BACKGROUND/STUDY CONTEXT: To date, little is known about how advancing age may impact perception of emotions in music. This study was designed to test whether there are age-related changes in emotional judgments and psychological structure for musical emotions.

This study examined whether a self-reported family history of alcohol abuse (FH+) moderated the effects of a female-specific group motivational enhancement intervention with first-year college women. First-year college women (N=287) completed an initial questionnaire and attended an intervention (n=161) or control (n=126) group session, of which 118 reported FH+. Repeated measures ANCOVA models...
In this manuscript we present various robust statistical methods and show how to apply them in R using the WRS2 package. We elaborate on robust location measures and present robust t-test versions for independent and dependent samples. We focus on robust one-way and higher order ANOVA strategies including mixed designs (“betweenwithin subjects”). Finally, we elaborate on running interval smooth...
The Corumbataí river is one of the main tributaries of the right margin of the Piracicaba river, itself a tributary of Tietê river. The Corumbataí is part of the Paraná river basin and is regionally important not only because of its good-quality water but also because the local landscape has unique features. This study aimed to characterize the fish assemblage of the Corumbataí in order to prov...
