Decision analysis tools and mathematical modeling are increasingly emphasized in malaria control programs worldwide to improve resource allocation and address ongoing challenges with sustainability. However, such tools require substantial scientific evidence, which is costly to acquire. The value of information (VOI) has been proposed as a metric for gauging the value of reduced model uncertainty. We apply this concept to an evidenced‐based Malaria Decision Analysis Support Tool (MDAST) designed for application in East Africa. In developing MDAST, substantial gaps in the scientific evidence base were identified regarding insecticide resistance in malaria vector control and the effectiveness of alternative mosquito control approaches, including larviciding. We identify four entomological parameters in the model (two for insecticide resistance and two for larviciding) that involve high levels of uncertainty and to which outputs in MDAST are sensitive. We estimate and compare a VOI for combinations of these parameters in evaluating three policy alternatives relative to a status quo policy. We find having perfect information on the uncertain parameters could improve program net benefits by up to 5–21%, with the highest VOI associated with jointly eliminating uncertainty about reproductive speed of malaria‐transmitting mosquitoes and initial efficacy of larviciding at reducing the emergence of new adult mosquitoes. Future research on parameter uncertainty in decision analysis of malaria control policy should investigate the VOI with respect to other aspects of malaria transmission (such as antimalarial resistance), the costs of reducing uncertainty in these parameters, and the extent to which imperfect information about these parameters can improve payoffs. 相似文献

Pure Gold for Broken Bodies: Discursive Techniques Constructing Milk Banking and Peer Milk Sharing in U.S. News

Technological advances provide increased ability to transfer human tissues—blood, organs, milk—from one body to another. This article analyzes mechanisms of reality construction in U.S. news to construct shared human breast milk. Articles used typifications and human interest stories to convey participants as victims, lay heroes, and villains. Milk banking was portrayed as institutionally integrated through associations, expert testimonies, and formalized procedures, making banked milk “pure gold.” Peer sharing was portrayed as institutionally opposed through institutional warnings, expert testimonies, informal procedures, and hypothetical atrocities, making peer milk “fool's gold.” Findings suggest that “biovalue” of human milk is interconnected with institutional processing. 相似文献

People with criminal records in the United States continue to face limited employment opportunities due to social stigma and legal barriers. In contrast to the civilian sector, the military conducts a “whole person” evaluation to screen potential recruits and regularly hires people with felony and misdemeanor records. Moreover, evidence suggests that the military serves as a socially integrative institution and may facilitate desistance from future crimes. However, critics argue that the military exacerbates inequalities by subjecting marginalized communities to the unequal burden of service. Using the data obtained from the Army, we examine the relative risks of combat exposure and casualties between enlisted soldiers with and without criminal records who joined between 2002 and 2009. The results suggest that soldiers with felony and misdemeanor records are more likely to be assigned to combat occupations than those without criminal records. We also find that among soldiers assigned to positions with low combat exposure, ex-offenders face a higher risk of death compared to those without criminal records. Findings do not dispute the idea that the military facilitates desistance from future crimes and provides second chances to people with criminal records, but reaffirm the fact that military service costs lives and limbs. 相似文献

This paper introduces the Ergonomic Work Analysis as a relevant instrument to identify the risks in occupational environments through the investigation of factors that influence the relationship between the worker and the productive process. It draws a parallel between the several aspects of risk identification in traditional tools of Health and Safety Management and the factors embraced by the Ergonomic Work Analysis, showing that the ergonomic methodology is able to go deeper in the scenarios of possible incident causes. This deepening enables the establishment of a relationship between the work context and the upcoming damage to the physical integrity of the worker. It acts as a complementary instrument in the traditional approach to the risk management. In order to explain the application of this methodology in a preventive way, it is presented a case study of a coal mill inspector in a siderurgic company. 相似文献

We investigate how to combine marginal assessments about the values that random variables assume separately into a model for the values that they assume jointly, when (i) these marginal assessments are modelled by means of coherent lower previsions and (ii) we have the additional assumption that the random variables are forward epistemically irrelevant to each other. We consider and provide arguments for two possible combinations, namely the forward irrelevant natural extension and the forward irrelevant product, and we study the relationships between them. Our treatment also uncovers an interesting connection between the behavioural theory of coherent lower previsions, and Shafer and Vovk's game-theoretic approach to probability theory. 相似文献

Studies of organizational dynamics examine the manner in which an organization's immediate environment defines the rules and requirements to which individual organizations must conform in order to receive legitimacy and support (Scott, 1992:132). In this paper we consider the question of how an organization can achieve legitimacy and support without necessarily compromising its organizational forms or practices to isomorphic pressures. We frame the question in terms of the boundaries between organizations and their environments. Where the population ecology studies show the survival value of adopting known organizational forms and practices, and neoinstitutionalism addresses the need to display compliance with accepted forms, our case study demonstrates the possibility of removing an organization or set of organizations from the familiar interaction by naming it as a subfield of the organizational field, sharing the environment, but out of the way of predefined norms and practices. 相似文献
