Demand for Pasture-Raised Livestock Products: Results from Michigan Retail Surveys

Pasture-raised livestock production offers opportunity for product differentiation and enhanced sustainability. Shopper surveys at three Michigan retail locations measured consumers’ attitudes and beliefs regarding pasture-raised livestock products, and willingness to pay for pasture-raised milk and beef. The shoppers associate pasture-raised products with attributes important to purchase decisions. The shoppers express willingness to pay, on average, about 35% more for pasture-raised milk and beef. Informational messages appear to have no effect on these responses. We suggest pasture-raised is a viable marketing strategy and recommend premium pricing strategies and promotion based on verifiable health benefits.animal welfare, consumer demand, pasture-raised livestock products, sustainability, Tobit, willingness to pay, Agribusiness, Demand and Price Analysis, Livestock Production/Industries,

Demand for Pasture-Raised Livestock Products in Michigan: Results of Consumer Surveys and Experimental Auctions

Pasture-raised livestock products present a niche-marketing opportunity for small- and medium-scale farmers; growth of this market may enhance the economic, social, and environmental sustainability of livestock agriculture. Results from an earlier statewide poll in Michigan found that consumers place great importance on product attributes associated with the pasture-based production model. This report presents findings from a combination of consumer surveys conducted at three Michigan retail locations and a series of experimental auctions. Participants in both the survey and auction components view pasture-raised beef and milk products very favorably, believing these products are healthy for humans to eat and are raised in environmentally friendly and humane ways. Survey respondents reported high likelihood of purchase; both the survey and auction subjects expressed willingness to pay a premium for pasture-raised products. We discuss these findings, particularly implications for the “four P’s†of marketing.Food Consumption/Nutrition/Food Safety, Livestock Production/Industries,

Beating of Aharonov-Bohm oscillations in a closed-loop interferometer

One of the points at issue with closed-loop-type interferometers is beating in the Aharonov-Bohm (AB) oscillations. Recent observations suggest the possibility that the beating results from the Berry-phase pickup by the conducting electrons in materials with the strong spin-orbit interaction (SOI). In this study, we also observed beats in the AB oscillations in a gate-defined closed-loop interferometer fabricated on a GaAs/AlGaAs two-dimensional electron-gas heterostructure. Since this heterostructure has very small SOI, the picture of the Berry-phase pickup is ruled out. The observation of beats in this study, with the controllability of forming a single transverse subband mode in both arms of our gate-defined interferometer, also rules out the often-claimed multiple transverse subband effect. It is observed that nodes of the beats with an h/2e period exhibit a parabolic distribution for varying the side gate. These results are shown to be well interpreted, without resorting to the SOI effect, by the existence of two-dimensional multiple longitudinal modes in a single transverse subband. The Fourier spectrum of measured conductance, despite showing multiple h/e peaks with the magnetic-field dependence that are very similar to that from strong-SOI materials, can also be interpreted as the two-dimensional multiple-longitudinal-modes effect

Shaking table tests and numerical analyses on a scaled dry-joint arch undergoing windowed sine pulses

The damages occurred during recent seismic events have emphasised the vulnerability of vaulted masonry structures, one of the most representative elements of worldwide cultural heritage. Although a certain consensus has been reached regarding the static behaviour of masonry arches, still more efforts are requested to investigate their dynamic behaviour. In this regard, the present paper aims to investigate the performance of a scaled dry-joint arch undergoing windowed sine pulses. A feature tracking based measuring technique was employed to evaluate the displacement of selected points, shading light on the failure mechanisms and gathering data for the calibration of the numerical model. This was built according to a micro-modelling approach of the finite element method, with voussoirs assumed very stiff and friction interface elements. Comparisons with existing literature are also stressed, together with comments about scale effects.This work was partly financed by FEDER funds through the Competitivity Factors Operational Programme-COMPETE and by national funds through FCT-Foundation for Science and Technology within the scope of the Project POCI-01-0145-FEDER-007633.info:eu-repo/semantics/publishedVersio

Salivary Inflammatory Mediator Profiling and Correlation to Clinical Disease Markers in Asthma

<div><p>Rationale</p><p>There is a need for a readily available, non-invasive source of biomarkers that predict poor asthma control.</p><p>Objectives</p><p>We sought to determine if there is an association between the salivary inflammatory profile and disease control in children and adults with asthma.</p><p>Methods</p><p>In this cross-sectional study, we collected demographic and clinical information from two independent populations at different sites, resulting in convenience samples of 58 pediatric and 122 adult urban asthmatics. Control was assessed by symptom questionnaire (children) and by Asthma Control Questionnaire and current exacerbation (adults). Saliva was collected in all subjects. We applied principal component analysis to a 10-plex panel of relevant inflammatory markers to characterize marker profiles and determined if profiles were associated with asthma control.</p><p>Results</p><p>There were similar, strong correlations amongst biologically related markers in both populations: eosinophil-related: eotaxin-1/CCL11, RANTES/CCL5, and IL-5 (p<.001); myeloid/innate: IL-1β, IL-6, MCP-1/CCL2, and IL-8/CXCL8 (p<.001). The first three principal components captured ≥74% of variability across all ten analytes in both populations. In adults, the Principal Component 1 score, broadly reflective of all markers, but with greater weight given to myeloid/innate markers, was associated with Asthma Control Questionnaire score and exacerbation. The Principal Component 3 score, reflective of IP-10/CXCL10, was associated with current exacerbation. In children, the Principal Component 1, 2, and 3 scores were associated with recent asthma symptoms. The Principal Component 2 score, reflective of higher eosinophil markers, was inversely correlated with symptoms. The Principal Component 3 score was positively associated with all symptom outcomes.</p><p>Conclusion</p><p>The salivary inflammatory profile is associated with disease control in children and adults with asthma.</p></div
