    A radio telemetry study of 76 nesting and brood rearing bobwhite quail (Colinus virginianus texanus) hens was conducted during 1980 and 1981. Four study sites with different habitats and cattle grazing intensities were used. The 1980 breeding season was hot and draughty. Nine nests were found and three clutches of eggs hatched. There was a 1:3 adult to juvenile ratio in fall shot birds, and 66 percent hatched after 1 September following the rains of Hurricane Allen on 9 August. The 1981 breeding season was wet with average temperatures. One nest was found and seven broods were known to have hatched . Examination of quail wings showed a 1:5 adult to juvenile ratio, with 69 percent of the juvenile birds hatched prior to July 16, 9 percent in the latter half of July, 10 percent in August, 9 percent in September, and 2 percent in October. Seven unsuccessful nests were found. Five were destroyed by predators and two were abandoned. Chick mortality was 49 percent within the first two weeks of life in nine broods. Thirty-eight of 76 radio tagged hens were killed during the reproductive seasons. Reproductive success was highest during the wetter breeding season and highest in pastures that were moderately grazed and in good range condition

    A Bayesian Reasoning Framework for On-Line Business Information Systems

    We describe a Bayesian Reasoning Framework (BRF) that supports business rule operations for on-line information systems. BRF comprises a three-layer environment with business information systems at the top, a middle-ware Bayesian reasoning server, and a Bayesian reasoning engine at the bottom. The top and middle-ware layers communicate via SOAP/XML protocol, while the middle-ware and bottom layers communicate via a Tag-value protocol that fetches business rules from a central repository. BRF is built as a Bayesian Reasoning Agent and tested in a helpdesk system for assigning advisors to users for trouble-shooting in the operation of business information systems. BRF is modeled following a use-case methodology as well as an inference modeling that uses an assignation template from Common- KADS. The concept, design and implementation of BRF for real-world, on-line business information systems are the main contribution of this research project

    Consensus statement on concussion in sport—the 5 th international conference on concussion in sport held in Berlin, October 2016

    Get PDF
    The 2017 Concussion in Sport Group (CISG) consensus statement is designed to build on the principles outlined in the previous statements1–4 and to develop further conceptual understanding of sport-related concussion (SRC) using an expert consensus-based approach. This document is developed for physicians and healthcare providers who are involved in athlete care, whether at a recreational, elite or professional level. While agreement exists on the principal messages conveyed by this document, the authors acknowledge that the science of SRC is evolving and therefore individual management and return-to-play decisions remain in the realm of clinical judgement. This consensus document reflects the current state of knowledge and will need to be modified as new knowledge develops. It provides an overview of issues that may be of importance to healthcare providers involved in the management of SRC. This paper should be read in conjunction with the systematic reviews and methodology paper that accompany it. First and foremost, this document is intended to guide clinical practice; however, the authors feel that it can also help form the agenda for future research relevant to SRC by identifying knowledge gaps

    Review of Deer of the Southwest: A Complete Guide to the Natural History, Biology, and Management of Southwestern Mule Deer and White-Tailed Deer.

    Very few books on the subject of deer in any particular region lend themselves to being complete. Jim Heffelfinger\u27s book breaks the mold. It is by far the most comprehensive book on mule deer and white-tailed deer in the southwestern part of the United States, including Plains portions of Texas, Colorado, and New Mexico, I\u27ve ever read. Everything you ever wanted to know about these two deer species can be found in its pages, starting from the natural history and early evolution of deer into the New World, separation into two species, selection of habitat types by the two, general management for these deer in the Southwest region, and specific southwestern state management programs. All of this under one cover and written in a style easy enough for the layperson to understand, but scientific enough for the professional biologist

    The role of weather in Class A Naval aviation mishaps FY 90-98

    Get PDF
    235 Class A Navy and Marine (Naval) aviation mishaps involving aircrew error between FY 90 and FY 98 are analyzed for the possibility of being weather related. In addition to determining the overall role of weather, weather related mishaps are compared to aircraft category, mishap characteristic, the Naval Safety Center human factors (HFACS) taxonomy, and flight phase. In addition, weather related mishap trends have been analyzed. Results show 19% of mishaps involving aircrew error are weather related with helicopter category and controlled flight into terrain (CFIT) mishap characteristic having the largest percent of weather related mishaps for their respective groupings. Visibility related weather elements account for over half of all weather related mishaps, and nearly two-thirds of all weather related mishaps were judged to be preventable with a perfect weather forecast believed by aircrew. These and other findings are presented to develop intervention strategies for reducing the number of weather related flight mishaps (FMs) per year.http://archive.org/details/theroleofweather109452400Lieutenant Commander, United States NavyApproved for public release; distribution is unlimited
