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

Semaan et al. (J Forensic Res, 2020, 11, 453) discuss a mock case “where eight different individuals [P1 through P8] could not be excluded in a mixed DNA analysis. Even though … expert DNA mixture analysis software was used.” Two of these are the true donors. The LRs reported are incorrect due to the incorrect entry of propositions into LRmix Studio. This forced the software to account for most of the alleles as drop-in, resulting in LRs 60–70 orders of magnitude larger than expected. P1, P2, P4, P5, and P8 can be manually excluded using peak heights. This has relevance when using LRmix which does not use peak heights. We extend the work using the same two reference genotypes who were the true contributors as Semaan et al. (J Forensic Res, 2020, 11, 453). We simulate three two-donor mixtures with peak heights using these two genotypes and analyze using STRmix?. For the simulated 1:1 mixture, one of the non-donors’ LRs supported him being a contributor when no conditioning was used. When considered in combination with any other potential donors (i.e., with conditioning), this non-donor was correctly eliminated. For the 3:1 mixture, all results correctly supported that the non-donors were not contributors. The low-template 4:1 mixture LRs with no conditioning showed support for all eight profiles as donors. However, the results from pair-wise conditioning showed that only the two ground truth donors had LRs supporting that they were contributors to the mixture. We recommend the use of peak heights and conditioning profiles, as this allows better sensitivity and specificity even when the persons share many alleles.  相似文献

ABSTRACT

Recently, “problem-solving” courts have been developed as an alternative to imprisonment. They are often called “specialty” courts because they process and divert into treatment programs offenders who are seen as different from the general criminal population, such as those with mental health or drug problems, those who are homeless or veterans, and those who engage in domestic violence. Based on a 2017 national survey of 1,000 respondents, the current study examines overall public support for rehabilitation as a goal of corrections and then focuses specifically on support for different types of specialty courts. The analysis reveals that the American public endorses not only the rehabilitative ideal but also the use of problem-solving courts. Further, with only minimal variation, strong support for these courts appears to exist regardless of political orientation and sociodemographic characteristics.  相似文献

This concept paper presents a theory of environmental scarcity developed byHomer-Dixon. Homer-Dixon developed a model to describe the consequences of scarcity for sub-national violence in third world countries. This paper hasfour interrelated purposes. First, it presents the model of scarcity developedby Thomas Homer-Dixon in 1999. Second, it assesses the way in which the scarcity model contextualizes criminal justice and criminology research, andby extension, how research in crime and justice processes can broaden the scarcity model. Third, it applies elements of the model to the United States,a goal that represents a generalization of the model from third-world to first-world settings. Fourth, it presents a particular case, the migrationof African-Americans from the rural South to urban centers in the 1950s and1960s and consequent inner-city violence in the 1960s, that displays manyelements of the environmental scarcity model.  相似文献

The Central Bank of Bahrain came into existence on 7 Septemberand has taken over all the tasks previously conducted by theBahrain Monetary Agency (‘BMA’). The Central Bankof Bahrain and Financial Institutions Law (‘CBB Law’)issued by Decree No. 64 of 2006 gives the CBB strong operationalindependence and a wider range of enforcement powers. The CBBLaw has also replaced the Insurance Law (Legislative DecreeNo. 17  相似文献

Several studies had concluded that the police subculture holds values and attitudes that are distinct from the rest of the population. Among these values is a focus on law and order. While researchers agree that police tend to hold different values, they disagree on the source of the attitudes. Some had argued that the attitudes reflected differences regarding who was recruited for law enforcement careers while others said that the differences reflected changes that occurred to individuals after becoming officers. This study examined whether police officers and students enrolled in criminal justice/sociology classes held similar or different attitudes towards the Miranda warnings. The findings suggested that in some ways, the two groups perceived the warnings in dramatically different ways, while in other ways their differences were simply a matter of degree. Implications are provided.  相似文献

The present study measured the existence of traumatic stress symptomatology as reported by certified law enforcement officers within the State of Delaware. A questionnaire was devised which documented age, sex, race, education, years of service, marital status, children, rank, position, and shift work. The questionnaire was divided into parts which assessed the exposure and the frequency of specific traumatic incidents experienced in the line of duty, and the frequency of experienced traumatic symptomatology criteria: re-experiencing, numbing, and arousal.  相似文献
