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

Public administration is a discipline with considerable history, and is also a diverse, interdisciplinary field in social science. To analyze its evolution, discover the present research foci, and predict future development trends, this study applied scientometrics visualization technology to evaluate over 72,000 scientific articles from the 1920s to 2020s. This research referred to the SSCI and JCR databases to gather scientific data of the discipline and the journals' impact factor. Consequently, paper citations, cited journals, journal co-citations, author co-citations, authoritative papers, top countries, productive institutes, average references, and research collaboration trends were analyzed on the bases of the published literature. This study found top productive journals in the discipline, discovered productive countries and institutes, present the research foci, and predicted future development trends. Through this study, scientific production, international cooperation, and knowledge evolution mode of public administration research offers a clear knowledge map of the public administration discipline. 相似文献

Gottfredson and Hirschi’s General Theory of Crime (GTC) has been one of the most cited and tested theories in criminology. It posits to be in effect transcultural in its application and relevant for any norm-violating behaviors. As most empirical work has been completed in English speaking countries, the current study tested some of the main theoretical postulates in a sample of 214 Argentinean male adolescents, both offenders and non-offenders. More specifically, it tested the relationships between parental practices, self-control, criminal opportunities, and deviance. Findings provide evidence that offenders reported more deviant behaviors and more risk factors than non-offenders. They also provide partial empirical support for the main theoretical propositions. Maternal closeness, support. and monitoring had different effects on self-control and on deviance; both low self-control and opportunities had direct effects of deviant behaviors. Theoretical, research, and practical implications of study findings are discussed. 相似文献

Local public services are produced through various overlapping jurisdictions. This study examines how the issuance of municipal general obligation bonds is affected by the tax policies of overlapping local governments. The findings challenge the hypothesis that the shared tax base would be overused in a common-pool resource scenario. Instead, the empirical results show that the issuance of general obligation bonds is more likely in jurisdictions where counties and school districts make more intensive use of the property tax. These findings highlight the importance of the signals local governments receive from their overlapping neighbors regarding voters’ demand for additional public spending. 相似文献

Hacking trauma is prevalent in forensic cases involving genocide and dismemberment, but research into the identification of this type of trauma is lacking. The present study examines characteristics of hacking and blunt force skeletal trauma in order to determine if there is a point at which blunt force trauma becomes distinguishable from hacking trauma. Ten implements with a range of blade angles (i.e., the striking surface of the implement) were used in conjunction with a controlled-force hacking device to impact 100 limb bones of white-tailed deer (Odocoileus virginianus). Observations of the trauma included the occurrence and degree of fragmentation, the entrance widths of the impacts, and composite scores of six hacking characteristics, especially the distinctive V-shaped kerf. ANOVA tests and regression analyses were used to assess the relationships between these characteristics and the blade angles. A significant relationship (p-value = 0.011) was found between the composite hacking scores and the blade angles, indicating that blunt force and hacking trauma can be distinguished. The entrance widths of the impacts exhibited a significant relationship with the blade angles (p-value = 0.037). There was also a significant relationship between the visibility of a V-shaped kerf in the bones (p-value = 0.003), with visibility decreasing around the 60° blade angle. These data should assist in establishing guidelines to differentiate hacking and blunt force skeletal trauma in cases where the implement is on a spectrum between sharp and blunt. 相似文献

Research indicates that voters are not particularly effective at removing corrupt politicians from office, in part because voters make decisions on the basis of many competing factors. Party leaders are much more single-minded than voters and will choose to deselect implicated legislators if it means maintaining a positive party reputation and improving the odds of winning a legislative majority. We examine renominations to Italy’s legislature in two periods marked by corruption. We compare these renomination patterns with those from the prior legislature, when corruption lacked political salience. Our analysis shows that incumbent renominations are negatively associated with the number of press mentions that link the incumbent to corruption—but only when corruption is salient to the public. Our study highlights the importance of party leaders in forcing malfeasant legislators out of office—and reducing corruption—and redirects attention from voters to political elites as a critical channel in enforcing democratic accountability. 相似文献

The media allow crime to infiltrate the public’s consciousness in every conceivable way, thereby playing a major role in shaping the public’s opinion and attitude toward crime and crime issues (Barak, 1995; Fields & Jerin, 1996; Kappeler & Potter, 2005). Reporters constantly talk about crime, and crime related stories dominate the headlines of local and national newspaper outlets (Dowler, 2003; Pizarro et al, 2007). Some of the most highly rated television programs are based on crime plots and people across social, political, and racial demographics are constantly engaged in crime dialogue generated from local or national news stories. When the focus of these mediums is on youth they become even more profound and contentious. The images portrayed conjure up stereotypes that lead to fear and inflammatory remarks that become entrenched into the national lexicon. The current study uses data from the National Opinion Survey of Crime and Justice to test the relationship between crime-related media viewership and fear of victimization within a nationally representative adult sample. Approximately 42.67% of respondents reported regularly watching crime shows and about the same proportion (42.83%) believed their local media paid too much attention to violent crime. In addition to regular crime-show viewership, confidence in the police, gender, and recent contact with the police were associated with fear of victimization. This article adds to an existing body of research through a largely unexplored area in the administration of justice. It does so within the context of the U.S. juvenile justice system. 相似文献

Postmortem magnetic resonance imaging (MRI) is rarely used for the radiologic assessment of gunshot injuries, although it has clear advantages over postmortem computed tomography (CT) with regard to the imaging of soft tissue injuries. Another benefit in using MRI is that lodged projectiles composed of nonferromagnetic material such as lead present only marginal metal artifacts compared with severe artifacts on CT. This case report presents CT and MRI findings in a case with two gunshot wounds to the neck: a perforating wound and a nonperforating wound with a lead bullet lodged in the cervical spine. The decedent underwent CT and MRI before the scheduled autopsy. A ring of radiopaque material under the dermis in the fatty tissue was identified at both entrance wounds on CT, which was indicative of contact shots. The perforating gunshot was clearly indicated on CT by bullet fragments along the wound channel through the perforated 6th cervical vertebra and the fractured cricoid cartilage at the exit wound. The second trajectory, however, was only assumed based on the presence of gunshot residues at the entrance wound and the position of the lodged bullet. The radiologic assessment was severely impeded by the metal artifacts on CT. Barely noticeable metal artifacts on MRI allowed for clear visualization of the soft tissue injuries and the ruptured medulla oblongata. Only MRI clarified the soft tissue injuries of the brainstem noninvasively, which could provide specific and graphic information on the rapidity of death and the incapacitation of the victim. 相似文献

The well‐known gap between law on the books and law in action often casts doubt on the significance of changes to law on the books. For example, the rise and fall of penal technologies have long been considered significant indicators of penal change in socio‐historical analyses of punishment. Recent research, however, has challenged the significance of apparently large‐scale penal change of this kind. This article clarifies the significance of penal technologies' rise and fall by offering an alternative account of formal penal change, introducing the analytical concept of “legal templates,” structural models of legal activity (e.g., punishment) available for authorization and replication across multiple jurisdictions. Analyzing punishment's templates explains how new penal technologies can be important harbingers of change, even when they fail to revolutionize penal practice and are not caused by a widespread ideological shift. This article locates the significance of punishment's legal templates in their constitutive power—their ability, over the long term, to shape cognitive‐cultural expectations about what punishment is or should be. This power appears only when the template is widely adopted by a plurality of jurisdictions, thereby becoming institutionalized. Ultimately, these institutionalized templates define the scope of future punishment. 相似文献
