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

The scope of directors’ duties forms perhaps the most important part of corporate governance. This paper considers the trajectory of the regulation of directors’ duties under Ghanaian company law from the Companies Act, 1963 (Act 179) to the Companies Act, 2019 (Act 992). Using the 2017 to 2019 financial institutions’ insolvencies in Ghana as a backdrop, it considers whether the scope, formulation and structure of directors’ duties within the new legislation is capable of promoting corporately-beneficial director behaviour. It also discusses whether the framework is apt to deal with similar lapses in corporate governance marked by reckless and opportunistic director behaviour. It discovers that Act 992 places a greater reliance on specific rules while retaining the largely principles-based regulatory technique adopted for regulating director conduct under Act 179. The overall tenor of the framework of directors’ duties under the new Act points to a firmer legislative view of the serious consequences of reckless director conduct. The paper concludes that the language of the framework regulating director conduct is capable of promoting corporately beneficially director behaviour and is also apt to deal with the kind of lapses in corporate governance which led to mass financial sector insolvencies in Ghana.  相似文献

In 1991 the FCC implemented a price cap plan for local exchange carriers' interstate access service designed to deal with the regulatory boundaries problem arising from the breakup of AT&T in 1984. The experience with the price cap plan demonstrates the difficulty of predicting productivity growth accurately and makes clear that regulators cannot depend upon a pure price cap plan to keep prices within a reasonable range of costs. With periodic reviews to readjust plan parameters, however, a price cap plan can maintain the rate-of-return close to the target rate-of-return without diminishing the price cap plan's incentives for efficient production. A simple method of recalculating the X-factor based on the rate-of-return over the previous three years worked well in simulations. If this procedure had been used over the price cap period 1991 to 2000, prices would have been 20 percent lower and expenditures on LECs' telecommunications service subject to a price cap would have been $3.8 billion lower.  相似文献

Families struggling with a breakdown in communication, trying to control the behavior of an unruly child, or experiencing a crisis often look for outside help. Many families, particularly those without resources to pay for private support, turn to their local status offense system. Status offenders are young people charged with behavior unique to their status as juveniles such as running away, truancy, or disobedience. In 2007, Congress will begin to consider reauthorization of the Juvenile Justice Delinquency Prevention Act (JJDPA), the federal act related to status‐offender policy. By providing an overview of recent state status‐offense legislation and case law, this article identifies issues to be addressed by Congress in reauthorizing the JJDPA.  相似文献

This paper explores the multi-layered representations of violence and crime in the recent Hollywood film Gangs of New York [Scorcese (2003) Miramax]. We use our exploration of this film to suggest that popular culture, even through its most mainstream products, can be seen as a critical criminological space where alternative views of law, crime and the state are made available. Rather than understanding Hollywood movies simply as vehicles for disseminating conventional mores, we suggest that they can furnish critical (and complex) points of view on law and crime and that the project of a critical criminology can be strengthened by engaging more forthrightly with these ubiquitous cultural forms.  相似文献

In 1997, the Office of Child Support Enforcement initiated the State Child Access and Visitation (AV) Grant Program, which involves annual awards of $10 million to states to promote the development of programs to alleviate access problems. Telephone interviews with 970 parents who used mediation, parent education, and supervised visitation programs funded by AV grants in nine states revealed that the programs are reaching diverse groups of parents including many low-income, non-White, and unmarried parents who receive no other type of access assistance. The programs also appear to be achieving the major objectives posited for them by the federal government. One-third to one-half of noncustodial parents in every program type reported that parent–child contact increased following program participation, with supervised visitation users who typically had the lowest levels of parent–child contact reporting a significant increase in the number of days of contact. A review of child support records for 173 program users in three states revealed that child support payments increased among participants following program participation, especially for never-married parents who paid a significantly higher proportion of what they owed. These findings are similar to results reported in a five-state study of mediation programs funded by AV grants that was conducted by the Office of the Inspector General. However, both studies have some serious limitations, including low response rates and the absence of a nontreatment comparison group.  相似文献
