BACKGROUND: Parents play a significant role in shaping youth physical activity (PA). However, interventions targeting PA
parenting have been ineffective. Methodological inconsistencies related to the measurement of parental influences may be a
contributing factor. The purpose of this article is to review the extant peer-reviewed literature related to the measurement...
BACKGROUND: Interventions to promote physical activity (PA) in children attending family child care homes (FCCHs) require valid, yet practical, measurement tools. The aim of this study was to assess the validity of two proxy report instruments designed to measure PA in children attending FCCHs. METHODS: A sample of 37 FCCH...
The purpose of this study was to evaluate the validity and inter-rater reliability of the Observational System for Recording Activity in Children: Youth Sports (OSRAC:YS). Children (N = 29) participating in a parks and recreation soccer program were observed during regularly scheduled practices. Physical activity (PA) intensity and contextual factors...
Research on the ecology of salmon in the northeast Pacific Ocean began in the early 20th century. Charles Gilbert and Willis Rich demonstrated the basis for the stock concept and were instrumental in changing common misconceptions of the times. Later in the 1900s, research endeavors, primarily under the auspices of...
California, Oregon and Washington, in cooperation with the National Marine Fisheries Service and the Pacific Marine Fisheries Commission, have initiated a coastwide Dungeness Crab Management Program. The primary objective of the program is to develop economic and biological information essential in supporting management decisions leading toward better management of the...
Objective: To translate a behavioral weight loss intervention for mid-life, low-income women in real world settings.
Design and Methods: In this pragmatic clinical trial, we randomly selected six North Carolina county health departments and trained their current staff to deliver a 16-session evidence-based behavioral weight loss intervention (special intervention, SI)....
Individual transferable quotas (ITQs) have been used in several countries worldwide to regulate access to
marine fisheries. While ITQs can improve the economic efficiency of fisheries, in practice they are not a
panacea and distribution and equity issues have been raised in many cases. To overcome those issues,
ITQ systems...
Studies on hydromineral balance in fishes frequently employ measurements of electrolytes following euthanasia. We tested the effects of fresh- or salt-water euthanasia baths of tricaine mesylate (MS-222) on plasma magnesium (Mg²⁺) and sodium (Na⁺) ions, cortisol and osmolality in fish exposed to saltwater challenges, and the ion and steroid hormone...
This paper describes the concepts and operations of two programs, SLASH, which simulates forest-residue populations, and INTRSCT, which performs line intersect residue inventories on these populations. Program SLASH creates residue pieces on a 5.07 -acre square area to specified orientation and spatial distributions. The user can specify constant geometric piece...
