Pediatric cancer is a tragedy that affects many American families. Despite the effectiveness of pediatric cancer treatments, patients experience adverse side effects that can be relieved by medical marijuana. However, medicinal marijuana is only lawful in twenty‐eight states, including the District of Columbia. This Note proposes that all fifty states enact compassionate‐use statutes permitting parents to lawfully possess and distribute the herb to their terminally ill child (between the ages of five to fourteen) to alleviate the effects of cancer treatments. Medicinal marijuana use provides pediatric cancer patients with better‐quality lives and the determination to win the war against cancer.  相似文献

While type determination on bullets has been performed for over a century, type determination on cartridge cases is often overlooked. Presented here is an example of type determination of ejector marks on cartridge cases from Glock and Smith & Wesson Sigma series pistols using Naïve Bayes and Random Forest classification methods. The shapes of ejector marks were captured from images of test‐fired cartridge cases and subjected to multivariate analysis. Naïve Bayes and Random Forest methods were used to assign the ejector shapes to the correct class of firearm with success rates as high as 98%. This method is easily implemented with equipment already available in crime laboratories and can serve as an investigative lead in the form of a list of firearms that could have fired the evidence. Paired with the FBI's General Rifling Characteristics (GRC) database, this could be an invaluable resource for firearm evidence at crime scenes.  相似文献

Huntington's disease (HD) is a relentlessly progressive and fatal neurological condition that is inherited. It has serious and disabling physical and mental components. As such, it impacts upon those who have HD, those with the potential to inherit it, and those who care for those with HD in a wide variety of ways. These can have many legal ramifications including in relation to evolving impairments of capacity which can have an outcome in terms of involuntary status as mental health patients, testamentary capacity and the need for guardianship and administration. It can have effects upon fitness for parenting, obligations for spousal maintenance, and the quantum of compensation from a tortious incident to which a person is entitled. It has repercussions for criminal liability and culpability. This article reviews case law from a number of countries in relation to such matters, noting the broader radiation to others of the effects of HD, and reflecting on the need for legal and medical professionals to be aware of the legal consequences of HD for them to be able to discharge their responsibilities holistically, sensitively and informedly.  相似文献

This article examines the Advocate-General's comments on the ‘hosting’ provision in the eCommerce Directive (00/31/EC). He suggests the existence of a ‘neutrality’ principle in respect of intermediary liability, which operates irrespective of an intermediary's knowledge about the legality or otherwise of the hosted content. This article critically examines this suggestion within the broader debate about the role and responsibilities of intermediaries in a cyberspace context.  相似文献

In National Life and Character (1893), Charles Pearson argued that the breakdown in “character” threatening social cohesion in Britain was a phenomenon that was replicated on a global scale in the late nineteenth century. The economic and technological progress that characterised the industrial revolution in Britain had stimulated urbanisation, and unleashed, Pearson claimed, a “bestial element in man”, degrading the quality of civic and economic life, and leading to a rising population of “stunted specimens of humanity”. Most analyses of National Life and Character focus on its fear of non‐white races and influence on policies of racial restriction; we argue that National Life and Character is a more ambitious work of political economy preoccupied, as Pearson observed, with the “self‐preservation” of the white European race, grappling with the tension of managing a potentially degraded population as new forms of state intervention, decline of traditional religious faith, and global expansion transformed white society, leaving it declining into a “stationary state” and vulnerable in the face of the rising non‐European peoples. These concerns were shared by many of the architects of Australian Federation, influencing the policy initiatives of the post‐Federation period.  相似文献

How can we better align private security with the public interest? This question has met with two answers in the literature on private security regulation, one seeking to cleanse the market of deviant sellers, the other to communalize the market through the empowerment of buyers. Both models of regulation are premised upon a limited neoclassical economic conception of how market transactions map onto the public interest. This article makes the case for a new model of regulation, one that seeks to civilize the market. Drawing upon the insights of economic sociology, our model regards the market for security as a moral economy in which commodity and non‐commodity values jostle and collide. On this basis, we propose a regulatory architecture where buyers and sellers are cast not only as economic actors but also as moral actors, revealing new avenues through which to encompass private security within the democratic promise of security.  相似文献

Legislatures differ in their institutional capacity to draft and enact policy. While strong legislatures can increase the congruence of policy outcomes to the electorate's preferences, they can also inject uncertainty into markets with their ability to alter the political economic landscape. We argue that this uncertainty will manifest in a state's ability to borrow and hypothesize a negative relationship between legislative capacity and creditworthiness. Using ratings of general obligation bonds issued by the American states over nearly two decades and data on the institutional capacity of state legislative assemblies, we find support for the claim that having a legislature that is better equipped to affect policy change increases credit risk evaluations. The results we present broaden our understanding of the importance of legislative institutions, the determinants of credit risk, and the economic implications of democratic responsiveness.  相似文献

Understanding psychosocial factors that affect the academic achievement of Hispanic adolescents remains a nationwide priority in the United States. Extending previous studies of the stressful effects of perceived discrimination, this year-long longitudinal study examined the correlates of perceived ethnic in-group rejection, coping strategies and fatalistic beliefs, on depressive symptoms, grades, and college aspirations of 2,214 Hispanic adolescents (54 % female) in Southern California. Based on the transactional model of stress and coping and on self-perception theory, structural equation models revealed that high perceived intragroup rejection (10th grade) and low levels of active coping (11th grade) were associated with depressive symptoms in 11th grade. Also, depressive symptoms partially mediated the link between intragroup rejection and both academic outcomes. Avoidant coping strategies (e.g., watching TV) also predicted depressive symptoms and were positively related to fatalism. In addition, fatalism was negatively related to grades and aspiration to attend college. The findings suggest the need to help adolescents find adequate outlets for communication and to create awareness about the potential effects of intragroup rejection.  相似文献
