Consumer Preferences for Pasture-Raised Animal Products: Results from Michigan

The pasture-based model of agriculture potentially offers opportunities for small- and medium-scale livestock producers in local, regional, and national markets. Our data indicate that many consumers value the attributes associated with locally produced pasture-raised products. We used ordered probit and binary probit analyses of these data to identify the demographic segments that showed the greatest interest in these attributes. This interest suggests a broad education and marketing effort to articulate salient attributes and to differentiate and increase the availability of these products in the marketplace.Demand and Price Analysis, Livestock Production/Industries,

The role of ECL2 in CGRP receptor activation: a combined modelling and experimental approach

The calcitonin gene-related peptide (CGRP) receptor is a complex of a calcitonin receptor-like receptor (CLR), which is a family B G-protein-coupled receptor (GPCR) and receptor activity modifying protein 1. The role of the second extracellular loop (ECL2) of CLR in binding CGRP and coupling to Gs was investigated using a combination of mutagenesis and modelling. An alanine scan of residues 271–294 of CLR showed that the ability of CGRP to produce cAMP was impaired by point mutations at 13 residues; most of these also impaired the response to adrenomedullin (AM). These data were used to select probable ECL2-modelled conformations that are involved in agonist binding, allowing the identification of the likely contacts between the peptide and receptor. The implications of the most likely structures for receptor activation are discussed.</jats:p

Report on the Joint Eglin Acoustic Week III

A series of three flight tests have been conducted at Eglin Air Force Base located in the Florida panhandle. The first was the Acoustics Week flight test conducted in September 2003. The second was the NASA Heavy Lift Rotorcraft Acoustic Flight Test conducted in October-November 2005. The most recent was the Eglin Acoustic Week III test conducted in August-September 2007. This series of tests have acquired acoustic data for a number of rotary and fixed wing aircraft that are used to generate noise semi-spheres used in predicting the acoustic footprint for prescribed flight operations. This extensive database can be used to determine the impact of flight operations on communities around a terminal area. Another valuable use of the semi-spheres is determining the long-range propagation of noise for civilian and military purposes. This paper will describe the third in this series of tests

EXISTENCE OF UNIQUE LIMITING PROBABILITY VECTORS IN STOCHASTIC PROCESSES WITH MULTIPLE TRANSITION MATRICES

Concepts associated with stochastic process containing multiple transition matricies are discussed. It is proved that under certain conditions, a process with m transition matrices has m unique limiting probability vectors. This result extends the notion of discrete Markov processes to problems with intrayear and interyear dynamics. An example using a large DP model illustrates the usefulness of the concepts developed to applied problems.Research Methods/ Statistical Methods,

Direct CFD Predictions of Low Frequency Sounds Generated by a Helicopter Main Rotor

The use of CFD to directly predict helicopter main rotor noise is shown to be quite promising as an alternative mean for low frequency source noise evaluation. Results using existing state-of-the-art grid structures and finite-difference schemes demonstrated that small perturbation pressures, associated with acoustics radiation, can be extracted with some degree of fidelity. Accuracy of the predictions are demonstrated via comparing to predictions from conventional acoustic analogy-based models, and with measurements obtained from wind tunnel and flight tests for the MD-902 helicopter at several operating conditions. Findings show that the direct CFD approach is quite successfully in yielding low frequency results due to thickness and steady loading noise mechanisms. Mid-to-high frequency contents, due to blade-vortex interactions, are not predicted due to CFD modeling and grid constraints

Health Professionals and Public Awareness of Carbon Monoxide Poisoning in Vermont

Introduction. Carbon monoxide (CO) is the second leading cause of non-medical poisoning death in the United States. Between 1999 and 2012, Vermont saw the highest rates of CO poisoning deaths in New England. Public education and the use of CO alarms have been identified as important prevention strategies. We developed and distributed a survey to assess public and health professional knowledge of CO. Methods. A 21-question survey was designed, based on the validated Chicago Lead Knowledge Test, to assess knowledge about sources of CO exposure and symptoms and treatment of poisoning. Fifteen additional questions collected occupational and demographic information and preferred sources of educational information. Surveys were distributed over two months to the public, healthcare professionals, and emergency responders within Chittenden County, as well as physicians throughout Vermont. Survey responses were analyzed using SPSS. Results. There were 256 respondents. Healthcare professionals performed better than public respondents overall (public: mean correct=15.69, SD= 2.83, N=104; healthcare provider and emergency responder: mean correct= 17.5, SD= 2.23, N= 152). The survey questions which were most frequently answered incorrectly related to treatment and sources of exposure, as well as the similarity of CO poisoning to symptoms of influenza. Respondents preferred to receive information from printed and internet sources. Discussion. Medical professionals are more knowledgeable about carbon mon- oxide than the general public. Public education should include printed and online for- mats, focusing on important sources of exposure (particularly ice rinks), seeking treatment following symptoms, and similarity to flu symptoms.https://scholarworks.uvm.edu/comphp_gallery/1267/thumbnail.jp

Joint Eglin Acoustic Week III Data Report

A series of three flight tests have been conducted at an Eglin Air Force Base remote test range located in the Florida panhandle. The first was the "Acoustics Week" flight test conducted in September 2003. The second was the NASA Heavy Lift Rotorcraft Acoustic Flight Test conducted in October-November 2005. The most recent was the Eglin Acoustic Week III test conducted in August-September 2007. This series of tests acquired acoustic data for a number of rotary and fixed wing aircraft and are used to generate noise semi-spheres used in predicting the acoustic footprint for prescribed flight operations. This extensive database can be used to determine the impact of flight operations on communities around a terminal area as well as for prediction code validations. Another valuable use of the semi-spheres is determining the long-range propagation of noise for civilian and military purposes. This paper describes the third test in this series. Data described in this report were acquired during testing of the MD-902 and Mi-8M aircraft. In addition, data acquired during a set of atmospheric propagation tests is also described

Investigating Demand for Weather Index Insurance: Experimental Evidence from Ethiopia

There is much interest in weather index insurance as a poverty‐mitigating tool, but concerns persist about potential demand for the product among the poorest of the poor. This paper relates the experiences in rural areas of Tigray region, Ethiopia through both commercial sign‐up data and a series of experimental games conducted to test demand for weather index insurance. Demand was observed to be considerable in both.Risk and Uncertainty,
