Strategies for Accessing Volume Markets in the Beef Industry: A Review of Three Case Studies

Given the increasing consolidation in the U.S. meat industry, smaller and specialty producers often have difficulty breaking into the market in profitable volumes. This paper examines three cooperative models for specialty beef producers. We offer a realistic examination of the potential for success of each model. Based on this, we identify the key attributes for a new model and offer guidance for future research efforts

The Rise and Fall of the Brazilian-American Military Alliance, 1942-1977

The article examines how the military alliance took shape in the early years of World War II, how the Brazilian Expeditionary Force became symbolic of Brazil’s war role, and how end of war decisions effected Brazil’s gains. Brazilian leaders promised more than they could deliver. The post war era saw less cooperation but continued efforts at maintaining good relations. Vargas to Geisel years brought shifts that ultimately led to unilateral renouncement of the alliance. Even so the two militaries sought to maintain ties where possible. The text sketches the long term relations and it is based on archival research

Contrast-enhanced micro-CT imaging in murine carotid arteries : a new protocol for computing wall shear stress

Background: Wall shear stress (WSS) is involved in the pathophysiology of atherosclerosis. The correlation between WSS and atherosclerosis can be investigated over time using a WSS-manipulated atherosclerotic mouse model. To determine WSS in vivo, detailed 3D geometry of the vessel network is required. However, a protocol to reconstruct 3D murine vasculature using this animal model is lacking. In this project, we evaluated the adequacy of eXIA 160, a small animal contrast agent, for assessing murine vascular network on micro-CT. Also, a protocol was established for vessel geometry segmentation and WSS analysis. Methods: A tapering cast was placed around the right common carotid artery (RCCA) of ApoE(-/-) mice (n = 8). Contrast-enhanced micro-CT was performed using eXIA 160. An innovative local threshold-based segmentation procedure was implemented to reconstruct 3D geometry of the RCCA. The reconstructed RCCA was compared to the vessel geometry using a global threshold-based segmentation method. Computational fluid dynamics was applied to compute the velocity field and WSS distribution along the RCCA. Results: eXIA 160-enhanced micro-CT allowed clear visualization and assessment of the RCCA in all eight animals. No adverse biological effects were observed from the use of eXIA 160. Segmentation using local threshold values generated more accurate RCCA geometry than the global threshold-based approach. Mouse-specific velocity data and the RCCA geometry generated 3D WSS maps with high resolution, enabling quantitative analysis of WSS. In all animals, we observed low WSS upstream of the cast. Downstream of the cast, asymmetric WSS patterns were revealed with variation in size and location between animals. Conclusions: eXIA 160 provided good contrast to reconstruct 3D vessel geometry and determine WSS patterns in the RCCA of the atherosclerotic mouse model. We established a novel local threshold-based segmentation protocol for RCCA reconstruction and WSS computation. The observed differences between animals indicate the necessity to use mouse-specific data for WSS analysis. For our future work, our protocol makes it possible to study in vivo WSS longitudinally over a growing plaque

Judges, Prosecutors, Jurors, and Organized Labor: Four Perspectives of Corporate Citizenship

Some people argue that the civil jury is in decline. They argue that it\u27s not really so important to be focusing on jurors and jurors\u27 views about corporate responsibility as it might have been in prior times. I want to raise some arguments in favor of the continuing importance of the civil jury. First of all, the cases that juries try may be very important cases in terms of the company and in terms of the role of the company vis-a-vis government regulation. Jurors are symbolic representatives of the public in the courtroom. Finding out what juries do when they look at the facts of the case, a missing memo, or a corporate executive explaining a memo, can give the parties an idea about what laypeople generally think about corporate action. Most important, the fact that we have a jury in some cases makes a difference in all the rest of the cases in the civil docket that settle rather than go to trial. Civil jury trial verdicts send signals to lawyers, judges, and companies about how the public perceives corporate behavior. So, in my view, it\u27s important to take a look at how juries think about issues of corporate responsibility in part to get a sense of public understanding of it and in part to understand how a jury might decide a specific case. From one perspective, the civil jury is seen as a modern-day Robin Hood. The civil jury is thought to be extraordinarily pro-plaintiff and quite anti-business. It is said to operate with a deep pockets approach. I put some of these beliefs about the jury to the test. In a nutshell, I found that the widespread beliefs about the civil jury in business cases are nearly as mythic as Robin Hood. In contrast to prevailing beliefs, the jurors I interviewed surprised me by being rather tough on plaintiffs who bring cases against businesses and corporations. Second, and this was also something of a surprise, I didn\u27t find a lot of anti-business prejudice. I asked participants in all of my studies a question about the appropriate standard for corporate responsibility: Should corporations be held to a higher standard of responsibility compared to individuals? I found that a number of people believed in similar treatment for individuals and corporations, with a substantial number also believing that corporations should be held to a higher standard. Jurors do treat corporations differently, but not for the reasons commonly believed. Jurors don\u27t treat corporations differently because they are overly sympathetic to plaintiffs, or because they have some sort of pre-existing animus against the corporate form or business in society. Rather, it appears that a corporation\u27s size, potential impact, organizational resources, or role responsibility encourage jurors to impose a higher level of responsibility

The Hayabusa Curation Facility at Johnson Space Center

The Japan Aerospace Exploration Agency (JAXA) Hayabusa spacecraft made contact with the asteroid 25143 Itokawa and collected regolith dust from Muses Sea region of smooth terrain [1]. The spacecraft returned to Earth with more than 10,000 grains ranging in size from just over 300 m to less than 10 m [2, 3]. These grains represent the only collection of material returned from an asteroid by a spacecraft. As part of the joint agreement between JAXA and NASA for the mission, 10% of the Hayabusa grains are being transferred to NASA for parallel curation and allocation. In order to properly receive process and curate these samples, a new curation facility was established at Johnson Space Center (JSC). Since the Hayabusa samples within the JAXA curation facility have been stored free from exposure to terrestrial atmosphere and contamination [4], one of the goals of the new NASA curation facility was to continue this treatment. An existing lab space at JSC was transformed into a 120 sq.ft. ISO class 4 (equivalent to the original class 10 standard) clean room. Hayabusa samples are stored, observed, processed, and packaged for allocation inside a stainless steel glove box under dry N2. Construction of the clean laboratory was completed in 2012. Currently, 25 Itokawa particles are lodged in NASA's Hayabusa Lab. Special care has been taken during lab construction to remove or contain materials that may contribute contaminant particles in the same size range as the Hayabusa grains. Several witness plates of various materials are installed around the clean lab and within the glove box to permit characterization of local contaminants at regular intervals by SEM and mass spectrometry, and particle counts of the lab environment are frequently acquired. Of particular interest is anodized aluminum, which contains copious sub-mm grains of a multitude of different materials embedded in its upper surface. Unfortunately the use of anodized aluminum was necessary in the construction of the clean room frame to strengthen it and eliminate corrosion and wear over time. All anodized aluminum interior to the lab was thus covered or replaced by minimally contaminating materials

Entrepreneurial search dynamics: reflection paper

The intended objectives of Smartspec Work Package 1 are firstly to identify related variety and value chain components within EU regions to inform specialisation choices and secondly, to identify the role of organisations and their interaction for the development of entrepreneurial discovery and to assess the role of network connectivity in facilitating intra- and extra-regional asset combination. In order to examine the various questions regarding the network and institutional factors enhancing or mitigating entrepreneurial search processes, in this work package we employ a twin-track multimethodology approach comprised of two parallel streams of enquiry, one of which is primarily empirical and quantitative in nature, and one of which is rather more conceptual and qualitative in nature. Each of these parallel streams of work is designed to progress and develop alongside the other, with various junctures built into the programme for mutual reflection and cross-fertilisation of ideas

Developing the New Hayabusa Curation Facility at Johnson Space Center

On 25 November 2005 the Japan Aerospace Exploration Agency (JAXA) Hayabusa spacecraft made contact with the asteroid 25143 Itokawa and collected a small amount of regolith dust from Muses Sea region of smooth terrain [1]. Even though optimal sample collection did not occur, the spacecraft returned to Earth with more than 10,000 grains ranging in the size from 30-180 microns [2]. These grains represent the only collection of pristine material returned from an asteroid by a spacecraft. As part of the joint agreement between JAXA and NASA for the mission, 10% of the Hayabusa grains will be transferred to NASA for parallel curation and allocation, the first 15 of which arrived in December 2011. In order to properly receive and process these samples, a new curation facility was developed at Johnson Space Center (JSC)
