Professional baseball players are often thought of as making multi-million-dollar salaries, but most professional baseball players have recently made under $15,000 a year. Minor league players toiled under an onerous system resulting from baseball's judicially created antitrust exemption and lobbying efforts that exempted them from minimum wage and overtime. These factors allowed teams to impose a uniform player contract (UPC) on players with numerous unconscionable provisions for years. However, a late-night Tweet in August of 2022 sent shockwaves through the sports and labor world, announcing that the Major League Baseball Players Association (MLBPA) was sending out authorization cards to represent minor league players. After years of fighting to maintain the authority to impose conditions on minor league players, through lobbying and litigation, Major League Baseball (MLB) turned over a new leaf and recognized the unionization of minor league players under the MLBPA less than three weeks later. In light of this long sought-after recognition, this article takes a novel approach. First, it provides historical context for baseball's unique ability to impose working conditions on minor leaguers without significant concern for legal ramifications. Second, it provides an overview of the doctrine of contractual unconscionability and analyzes the prior UPC as an unconscionable agreement. Finally, it details the historic unionization process and makes detailed recommendations to ameliorate the unconscionable conditions minor league players have faced when they negotiate with MLB owners to draft their initial collective bargaining agreement. 相似文献

In response to research demonstrating that irrelevant contextual information can bias forensic science analyses, authorities have increasingly urged laboratories to limit analysts' access to irrelevant and potentially biasing information (Dror and Cole (2010) [3]; National Academy of Sciences (2009) [18]; President's Council of Advisors on Science and Technology (2016) [22]; UK Forensic Science Regulator (2015) [26]). However, a great challenge in implementing this reform is determining which information is task-relevant and which is task-irrelevant. In the current study, we surveyed 183 forensic analysts to examine what they consider relevant versus irrelevant in their forensic analyses. Results revealed that analysts generally do not regard information regarding the suspect or victim as essential to their analytic tasks. However, there was significant variability among analysts within and between disciplines. Findings suggest that forensic science disciplines need to agree on what they regard as task-relevant before context management procedures can be properly implemented. The lack of consensus about what is relevant information not only leaves room for biasing information, but also reveals foundational gaps in what analysts consider crucial in forensic decision making. 相似文献

AbstractGoals in the public sector are complex and managers can face situations in which pursuing one legitimate goal necessitates performance trade-offs in other areas. This study tests how knowledge of legitimate performance trade-offs shapes the perception of red tape. Using a vignette experimental design and a sample of university students, between group t-tests and regression analyses suggest that, when evaluating increased rule burden, individuals that are provided with information about how objectively burdensome rules serve alternative values such as equity and effectiveness associate them with lower levels of red tape. A series of Monte Carlo simulations suggest that this effect is substantial. 相似文献

ABSTRACTIncreasingly, a diverse set of policy communities, including those with defence, development and environmental mandates, frame climate change as a security threat. Most often this discursive formation labels climate change as a ‘threat multiplier’. This framing, however, is vague, linear and leaves many questions unanswered regarding how institutions can develop and implement policy that addresses the joint challenges of climate change, conflict and security. Utilising a mixed-methods approach, and grounding data collection in US policy communities, this article examines how policy actors and institutions integrate climate-security discourses into policy processes. The objective of this research is to provide direct insight into how the discourses and technical understandings of climate-security transition into policy priorities and implementation realities. This research identified three common approaches to climate-security: (1) A challenge of adaptation and resilience; (2) A potent political argument; and (3) An issue of limited importance and feasibility. These approaches, however, are inconsistent across sectors and within organisations, suggesting a lack of cohesion and considerable challenges in identifying and responding to climate change as a ‘threat multiplier’. 相似文献

What drives policymakers to put the interests of others above their own? If human nature is inherently selfish, it makes sense to institutionalize incentives that counter decision makers' temptations to use their positions to benefit themselves over others. A growing literature rooted in evolutionary theories of human behavior, however, suggests that humans, under certain circumstances, have inherent predispositions towards “representational altruism,” i.e., to make an authoritative decision to benefit another at one's own expense. Drawing on Hibbing and Alford's conception of the wary cooperator, a theoretical case is made for such behavioral expectations, which are confirmed in a series of original laboratory experiments. 相似文献

Restriction fragment length polymorphism (RFLP) analysis for the purpose of individualization is now being used in casework in the People's Republic of China. This report describes the use of the multilocus minisatellite probe 33.15 to solve three cases, including two homicides and a rape. In the third case, fetal tissue was analyzed to prove that the alleged rapist was, in fact, the father. In each case, analysis of deoxyribonucleic acid (DNA) resulted in a positive match. The probability of chance association of the DNA fingerprint was calculated as 5.6 x 10(-12), which is similar to the figures reported in the literature. 相似文献
