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

This research note argues that the “lone wolf” typology should be fundamentally reconsidered. Based on a three-year empirical research project, two key points are made to support this argument. First, the authors found that ties to online and offline radical milieus are critical to lone actors' adoption and maintenance of both the motive and capability to commit acts of terrorism. Second, in terms of pre-attack behaviors, the majority of lone actors are not the stealthy and highly capable terrorists the “lone wolf” moniker alludes to. These findings not only urge a reconsideration of the utility of the lone-wolf concept, they are also particularly relevant for counterterrorism professionals, whose conceptions of this threat may have closed off avenues for detection and interdiction that do, in fact, exist. 相似文献

This article investigates off-farm work decisions by smallholder farm households. Using data on 1,101 households from Burkina Faso, it demonstrates that in addition to the usual household socio-demographic characteristics, remittances, access to information and beneficiary of specific training affect off-farm work decisions, as well as rainfall factors and idiosyncratic health shocks. Community characteristics such as accessibility and number of inhabitants are also key factors. While suggesting that off-farm work is less likely to be undertaken for accumulation purposes, these results have important policy implications. In particular, policy measures should consider each segment as a separate entity. 相似文献

AbstractThis article reports and discusses the results of a study that investigated photographic images of children in five online terrorist magazines to understand the roles of children in these groups. The analysis encompasses issues of Inspire, Dabiq, Jihad Recollections (JR), Azan, and Gaidi Mtanni (GM) from 2009 to 2016. The total number of images was ninety-four. A news value framework was applied that systematically investigated what values the images held that resulted in them being “newsworthy” enough to be published. This article discusses the key findings, which were that Dabiq distinguished different roles for boys and girls, portrayed fierce and prestigious boy child perpetrators, and children flourishing under the caliphate; Inspire and Azan focused on portraying children as victims of Western-backed warfare; GM portrayed children supporting the cause peacefully; and JR contained no re-occurring findings. 相似文献

ABSTRACTRecently, “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

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
