Why Trade Associations Matter: Exploring Function, Meaning, and Influence

We explore the organizational characteristics of trade associations (TAs) and suggest theoretical approaches for undertaking research into or involving TAs in management and organization studies. Through emphasizing the role of TAs within and between industries and at the interface of business and society, we consider how TAs generate meaning and influence

User-Fee Financing of USDA Meat and Poultry Inspection

USDA's Food Safety and Inspection Service (FSIS) finances about 13.5 percent of its budget outlays through user fees for overtime and unscheduled meat and poultry inspections. User fees play an increasingly important role in financing government programs, and FSIS has frequently requested expanded authority to charge user fees for more of its operations. Congress has consistently rejected the FSIS requests and has placed important restrictions on fees and the uses of fee revenue at those agencies that have been granted more extensive user fee authority. This report surveys the application of user-fees for financing meat and poultry inspection programs in other countries; reviews user-fee systems in other Federal agencies, particularly those with food and agricultural missions or regulatory responsibilities; and discusses the relevant economics literature on the use and design of user fees. Finally, we suggest several elements that should underlie the structure of user fees for meat and poultry inspection, should such a program be introduced. euser fees, meat inspection, public finance, Livestock Production/Industries, Public Economics,

Effect of a dry acidulant coating on the palatability of dry extruded dog food

Journal of Animal Science, 94, 114-114. doi:10.2527/msasas2016-242In the pet food industry, Salmonella is getting greater scrutiny because it is considered a “reasonably foreseeable hazard” with the implementation of the Food Safety Modernization Act. Specifically, there is zero tolerance for any serotype of Salmonella in pet foods. Salmonella contamination was responsible for 78% of the Class I recalls in pet food according to the most recent Reportable Food Registry Report (FDA, 2015). One potential method of Salmonella mitigation shown to be effective was through coating the exterior of the kibble with a powdered dry acidulant, such as sodium bisulfate (SBS; Jones-Hamilton, Co.). Sodium bisulfate coating on both dog and cat kibbles was shown to provide complete mitigation of Salmonella within 14-d storage (Jeffrey et al., 2014). However, it is thought that the use of dry acidulant with a palatant for coating kibble may negatively impact palatability of a dry dog food. Therefore, the objective of this experiment was to determine if the use of a dry acidulant, SBS, would influence the palatability of a dry dog food. A single dry extruded all life stages dog food was collected from a commercial pet food manufacturer before the coating step. The kibble was coated with either 2.2% spray dried chicken liver + 0.2% SBS or 2.2% spray dried chicken liver + 0.2% powdered silica (control). A total of 20 beagles were used in a standard 2-bowl forced choice palatability test method for 2 d. Dogs were fed 400 g of both diets once per day, with bowls rotated daily to address side bias. Results were analyzed using the GLIMMIX procedure of SAS (Cary, NC). The inclusion of SBS did not affect daily preference of diet (P = 0.23). Furthermore, there was no effect of day (P = 0.18) or the interaction of treatment × day (P = 0.98). These results demonstrate that palatability is not affected by the inclusion of SBS with a palatant in the coating of dog food kibble. Considering that the inclusion of SBS has been shown to be effective at mitigating Salmonella in pet food and no negative effects on palatability were observed, the use of a dry acidulant in a dog food coating gives the industry a promising method to control Salmonella contamination of finished dog foods

Attractant Pheromone of the Neotropical Species Neomegalotomus parvus (Westwood) (Heteroptera: Alydidae).

The Neotropical broad-headed bug, Neomegalotomus parvus (Westwood), is adapted to various leguminous crops and is considered a pest in common bean and soybean. The chemical communication of this species was studied in order to identify an attractant pheromone. Males and females of N. parvus produce several short-chain esters and acids, and their antennae showed electrophysiological responses to ?ve of these compounds, three common to both sexes (hexyl butanoate, 4-methylhexyl butanoate, and hexyl hexanoate), and two female-speci?c compounds (4-methylhexyl pentanoate and hexyl pentanoate). Both aeration extracts of females and a solution containing ?ve synthetic compounds mimicking the natural blend were attractive to males and females N. parvus in a laboratory bioassay. Aspects of the chemical ecology of the broad-headed bugs and the possibility to use pheromone-baited traps in the ?eld for monitoring are discussed

Segmental Duplications: a Possible Mechanism of Hominid Uplift Through MicroRNA Diversification

MicroRNAs (miRNA) are ~21 nucleotide-long gene silencers. Segmental duplications (SD) are among the driving forces in acquiring new genes. Both miRNA and SD are believed to have played a significant role in evolution, particularly in the divergence of humans (Homo sapiens) from the chimpanzee (Pan troglodytes). This study determines the distribution of miRNAs in humans and in chimpanzees, and presents a hypothesis on its significance in the occurrence of segmental duplications. MiRNA sequences from miRBASE were subjected to BLAT and BLAST to determine if miRNAs are located in SD regions or not. Homology between miRNAs was determined with ClustalW. BLAST was then used to determine whether the non-homologous human miRNA are homologous to any other part of the chimpanzee genome. We found that all 695 human miRNAs are found exclusively in SD regions, and that 67 are de novo miRNAs. Thirteen are homologues of chimpanzee miRNA, and 11 were possibly derived from non-miRNA regions in chimp. Of these, 6 were located in SD regions of the chimpanzee genome. Results indicate that miRNA evolution occurs within regions of segmental duplication and suggest that the presence of miRNA duplicates allows more exposure to mutations that could necessitate diversification, and possibly evolution, through sub- and neofunctionalization

Weaning from Mechanical Ventilation

For most patients who require mechanical ventilation weaning and extubation is simple. In these patients a variety of strategies can be successful. In addition, sim ple criteria may predict when the patient is ready for extubation. For the small group of patients who require prolonged mechanical ventilation, however, contro versy exists about how best to remove ventilator sup port by weaning, and available data are sparse. Much of the controversy has centered on T-piece weaning ver sus intermittent mandatory ventilation. To date no con trolled study has demonstrated the superiority of either intermittent mandatory ventilation or T-piece weaning in difficult-to-wean patients. In the evolution of this con troversy, concern has developed over the potential for increased inspiratory work and expiratory resistance that may be associated with certain intermittent manda tory ventilation systems. The possibility that significant inspiratory work may occur during assist-control venti lation has also been demonstrated. Respiratory muscle weakness and fatigue is likely important in failure to wean. Other possible causes are failure of the cardiovas cular system and impaired ability of the lung to carry out gas exchange. In this article we first examine criteria and techniques for weaning short-term ventilator pa tients. We then examine criteria to begin the weaning process in prolonged ventilation patients, potential causes of failure to wean, and techniques that can be used to remove ventilator support from patients who are difficult to wean. Much literature has been devoted to techniques and criteria for weaning and extubation of patients from mechanical ventilation. For most patients who require ventilatory support, weaning and extuba tion can be easily accomplished by a variety of tech niques [1-4]. At one referral center 77.2% of all surviving patients were weaned from the ventilator within 72 hours of the onset of mechanical ventila tion, and 91% were weaned within 7 days [1]. Less than 10% of ventilated patients potentially posed problems in weaning from mechanical ventilation. Similarly, at a community hospital, few surviving patients required prolonged ventilatory support [2]. In easy-to-wean patients, Sahn and Lakshminarayan [5] described simple criteria that are predictive of successful discontinuation of ventilator support. For the small group of patients who require pro longed mechanical ventilation, however, minimal data are available. In these patients criteria to deter mine weaning ability or which measurements to follow are not clearly defined. Furthermore, no controlled trials are available to compare the differ ent weaning techniques proposed. In this article we first address routine weaning of the patient who has not required prolonged ventilator support. We then examine the difficult-to-wean patient and dis cuss criteria to begin the weaning process, poten tial causes of failure to wean, and available weaning techniques.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68923/2/10.1177_088506668800300207.pd

Spectrum of Neutral Helium in Strong Magnetic Fields

We present extensive and accurate calculations for the excited state spectrum of spin-polarized neutral helium in a range of magnetic field strengths up to $10^{12}$ G. Of considerable interest to models of magnetic white dwarf stellar atmospheres, we also present results for the dipole strengths of the low lying transitions among these states. Our methods rely on a systematically saturated basis set approach to solving the Hartree--Fock self-consistent field equations, combined with an ``exact'' stochastic method to estimate the residual basis set truncation error and electron correlation effects. We also discuss the applicability of the adiabatic approximation to strongly magnetized multi-electron atoms.Comment: 19 pages, 7 figures, 10 table
