Most corporations probably do not consider their in-house counsel to be potential qui tam threats. That may be a naive assumption. Case law provides an illustrative view of the legal ramifications involved when an attorney brings a qui tam suit. In general, there is no prohibition on attorneys who wish to bring these actions. Nevertheless, a corporation can take preventive steps to eliminate the likelihood of attorney qui tam actions. In addition, the corporation can take advantage of state professional ethics laws to mount a defensive action against the attorney who files any such action.  相似文献

The conflict between notions of fairness and the Pareto principle   总被引:2,自引:0,他引:2  
Most legal academics and policy makers believe that notionsof fairness should be accorded positive weight in evaluatinglegal policies. We explain, however, that ascribing importanceto any notion of fairness (other than one concerned solely withthe distribution of income) will sometimes lead to a conflictwith the Pareto principle. That is, to endorse a notion of fairnessis to endorse the view that it can be desirable to adopt a legalrule that will reduce the well-being of every person in society.  相似文献

A statistical investigation of the relationship between firing range and the amount and distribution of gunshot residue (GSR), used automated image analysis (IA) to quantify GSR deposit resulting from firings into pig skin, from distances ranging between contact and 45 cm. Overall, for a Ruger .22 semi-automatic rifle using CCI solid point, high velocity ammunition, the total area of GSR deposit on the skin sections decreased in a non-linear fashion with firing range. More specifically there were significant differences in the amount of GSR deposited from shots fired at contact compared with shots fired from distances between 2.5 and 45 cm; and between shots fired from a distance of 20 cm or less, with shots fired at a distance of 30 cm or more. In addition, GSR particles were heavily concentrated in the wound tract only for contact and close range shots at 2.5 cm, while the particle distribution was more uniform between the wound tract and the skin surfaces for shots fired from distances greater than 2.5 cm. Consequently, for future scientific investigations of gunshot fatalities, once standards have been established for the weapon and ammunition type in question, image analysis quantification of GSR deposited in and around the gunshot wound may be capable of providing a reliable, statistical basis for estimating firing range.  相似文献

Despite the persistent efforts of federal tax policymakers to place binding constraints on the economic development bond market in the United States, it has grown since the Tax Reform Act of 1986 and is a well established segment of the municipal securities market. This article provides an analysis of the development bond market by describing tax increment debt finance (TIF) in the United States and conducting an empirical analysis of California TIF debt. Our analysis indicates that tax increment debt finance (TIF) is no longer an obscure infrequently used financing tool, but for local governments in many states is a commonly used means of raising capital for multiple purposes. Our empirical analysis highlights the unique project-specific features of tax increment finance that bond issuers must understand and manage to enhance the credit quality and minimize the financing costs of tax increment debt.  相似文献

This study examines the association of self-perceptions with sixth to eighth graders' exposure to mixed-sex and dating contexts. It contrasts two hypotheses: the stress hypothesis, which suggests that the transition to romantic relationships will be associated with declines in self-esteem, especially for girls, and the leisure hypothesis, which suggests that movement into a desired role in an emotionally positive social context will be associated with positive emotions and higher self-esteem. Results indicate that adolescents experience mixed-sex settings positively, and that comfort with the other sex (for girls) and more time spent with the other sex (for boys) are predictive of more positive self-perceptions. Activity diary data suggest that these differences are due to differences in the emotional climate of same- and mixed-sex settings, rather than to the activities adolescents engage in with same- and mixed-sex groups. Dating boys who are less interested in dating experience lower self-esteem. Results are discussed in light of the transitional nature of mixed-sex relationships in early adolescence and the preparatory role played by same-sex friendships.  相似文献
