Religious diversity and entrepreneurship in transition: lessons for policymakers

Using the 2010 Life in Transition Survey, we show that localities with higher religious diversity have more respondents who have tried to set up a business. Although religious diversity also correlates with a higher start-up probability (following trial), this effect is driven by access to finance and risk preferences. We provide suggestive evidence that the positive association between religious diversity and entrepreneurial trial is positively moderated by social capital (when measured as access to weak ties and the ability to bridge structural holes). Our results suggest that programs which encourage entrepreneurial attempts in diverse areas and develop such social capital are likely to be particularly effective. At the start-up stage, relaxing credit constraints should rank high on the policy agenda

Survey of Cattle Feedlot Facilities in the High Plains Region of the United States

Defining the appropriate dimensions and type of feeding facilities for feedlot cattle fed in outdoor pens is important because the characteristics of these facilities have a significant impact on the performance, welfare, and health of cattle housed in those facilities, as well as a considerable impact on the final cost of the project. Although multiple sources can be found in the literature that provide recommendations with regard to design of facilities to be used in outdoor feeding facilities for feedlot cattle, there are no published data that describe the dimensions and type of feeding facilities currently used by the feedlot industry in outdoor feeding operations. Thus, the objective of this survey was to obtain descriptive data regarding outdoor cattle feeding facilities currently used by feedlots in the High Plains region of the United States

Prevalence of Horns in a Pen Does Not Affect Incidence of Carcass Bruising in Feedlot Cattle

Disbudding and dehorning are two common practices done to remove horns from cattle to prevent injury to handlers and other cattle and to reduce bruising of carcasses. Bruised carcasses result in substantial reduction in profit due to trim loss, increased sanitation risk, and loss in time on the rail during processing. Previous research has indicated that cattle with horns increased hide damage of cohorts and caused injury to handlers. Cattle with horns cause circular shaped bruises that lead to trim loss due to bruising. Cattle with tipped horns do not have a lower bruising rate than cattle with intact horns. The objective of this study was to evaluate the effect of horn prevalence within groups of slaughter animals and the incidence of bruising on the carcasses of those same cattle

Bulls Are More Efficient Than Steers with Similar Meat Quality

Bull breeding soundness evaluations are often performed as a critical component of beef cow herd management to ensure that herd bulls have adequate semen quality, are physically capable of enduring the breeding season, and to determine the serving capacity per bull. Currently, there are approximately 30.3 million beef cows and 2.1 million bulls in the U.S. Depending on the breeding soundness evaluation failure rate, there are likely several hundred thousand bulls which will enter the beef market annually and a portion will be young bulls with the potential to be fed and sold to produce saleable meat of choice or select quality grade. Castration of male cattle is a common procedure that is practiced world-wide, but is more common in the U.S. than in many countries. Behavioral benefits from castration include reduced aggressiveness and sexual activity by reducing testosterone levels. In addition, castrated animals maintain a lower muscle pH post-harvest producing fewer “dark cutters.” Bulls have greater feeding performance and efficiency than steers. However, a bull’s ability to gain efficiently and produce a leaner carcass, with more value to the packer and retailer, is overshadowed by the perception that meat from bulls is less tender than meat from steers. Castration methods and the age at castration influence the potential stress on the animal, resulting in concerns regarding animal welfare and animal performance; therefore, castration of post-pubertal bulls to improve meat quality should be re-evaluated. The objective of this study was to evaluate the effects of castration and the use of growth promotion technologies in post-pubertal bulls on feeding performance, carcass traits, and meat quality characteristics compared to intact post-pubertal bulls

A Monte Carlo Rollout algorithm for stock control

The application of optimization in industrial processes is faced with many challenges. One of the main challenge is the possible inaccuracy of information. In contrast to mathematical optimization theory, information is not completely known a priori. Often information can only be estimated or changes over time. Another challenge is the need of a decision in real time. Both points are relevant for a control of a flexibly designed in-plant block storage. The schedule plan for storages and removals should be able to adapt quickly to changes. In this paper an algorithmic approach is presented which is able to react on dynamic and uncertain changes due to the production process. To this end, optimization algorithms are implemented within a rolling planning process, so it is possible to respond to updated information by adapting the current plan. A novel optimization method is developed to generate cost effective and robust solutions by looking ahead into the future
