Washington University v. Catalona revolves around ownership of tissue samples provided by patients for research purposes, raising significant ethical and legal questions concerning patient rights, current human research practices, and the treatment of samples as capital resources by the research institution. 相似文献

Here we consider two ways that nanomedicine might be disruptive. First, low-end disruptions that are intrinsically unpredictable but limited in scope, and second, high end disruptions that involve broader societal issues but can be anticipated, allowing opportunity for ethical reflection. 相似文献

This synoptic article focuses on the origin and functioning of the Office of the Family Advocate as the protector of the interests of minor children in divorce cases. Attention is paid to the general contemporary trend to specialise in judicial decision-making that developed out of an increasing need for expertise in the administration of justice. A number of arguments for and against judicial specialisation are addressed. The origin of the Office of the Family Advocate within the South African judicial system is discussed and a brief exposition of the history of divorce legislation in South Africa is given. This is followed by attention to the functioning of the Office of the Family Advocate with reference to the process followed in investigations of this office and points of criticism against the system are highlighted. The article closes with an indication of the need for research in this regard and possible focus points for future research are identified. 相似文献

The increased risk of child maltreatment in the presence of domestic violence is well documented, but much remains unknown about factors that modify this relationship. This study investigates the roles of risk and protective factors in the relationship between domestic violence and being reported to the Department of Social Services for child maltreatment. Consistent with the literature, we find a significant overlap between domestic violence and maltreatment. Young maternal age, low education, low income, and lack of involvement in a religious community add to the risk for maltreatment associated with domestic violence. Separation between the maternal caregiver and her partner significantly reduces the risk for maltreatment when domestic violence is reported. A significant reduction in the risk for maltreatment is also found with higher levels of support from the maternal caregiver reported by the child in the context of domestic violence. 相似文献

In the same way that larceny characterized much of twentieth century, fraud will likely characterize the twenty-first century.
Larceny remains the most common oi all serious crimes, but fraud may overtake larceny as the crime of choice in the future,
because of changes in our ownership, storage, and movement of property. Fraud involves purposely obtaining the property of
another through deception, and its popularity as a crime of choice is growing. Entrusting property to the custody oi others,
storing property at remote locations, and electronic movement of property are shown to be major changes in the way we treat
property and increase opportunities for theft. The connection between fraud and many of the serious crimes of the twenty-first
century are shown in the facts of recent cases. The motivation of thefl behind many frauds is also shown to be used to fund
larger criminal objectives, such as illegal immigration and terrorism.
The points of view expressed are those of the author and do not necessarily reflect the position or policies of the U.S. Department
of Justice. Dr. Albanese is chief of the International Center at NIJ on leave from his position as professor of Government
and Public Affairs at Virginia Commonwealth University. 相似文献

We consider the problem of drawing inferences within a legal framework when a person is a suspect for two separate offences. Although we are primarily concerned with scientific evidence the issue inevitably arises as to how that evidence interacts with other, non-scientific evidence. We show that, in this particular context, the evidence can be conveniently classified into three categories that concern, respectively: the first crime only; the second crime only; and evidence that relates to similarities between the two crimes. Two case examples are considered and we consider DNA, fibres and eyewitness evidence. These are viewed from the perspective of a prosecutor who has to decide whether or not to charge a suspect with one or both crimes. Graphical sensivity analyses are presented which have features that are not intuitively obvious. 相似文献

The link between resource deprivation and urban violence has long been explored in criminological research. Studies, however, have largely ignored the potential for resource deprivation in particular communities to affect rates of violence in others. The relative inattention is notable because of the strong theoretical grounds to anticipate influences that extend both to geographically contiguous areas and to those that, though not contiguous, share similar social characteristics. We argue that such influences—what we term spatial and social proximity effects, respectively—constitute a central feature of community dynamics. To support this argument, we develop and test theoretically derived hypotheses about spatial and social proximity effects of resource deprivation on aggregated and disaggregated homicide counts. Our analyses indicate that local area resource deprivation contributes to violence in socially proximate communities, an effect that, in the case of instrumental homicides, is stronger when such communities are spatially proximate. We conclude by discussing the implications of our findings for theories focused on community‐level social processes and violence, and for policies aimed at reducing crime in disadvantaged areas. 相似文献

Family lawyers are major beneficiaries of the reforms set out in the Family Law Education Reform Project (FLER) Report. This commentary from a veteran family law practitioner explores the needs of the family law bar for the training of law students in practical, interdisciplinary, client‐centered lawyering that goes beyond the traditional case method. I trace many of the current innovations evolving in family law practice and how FLER reforms will not only benefit law schools but also have a major impact in the courts and private practice sector. 相似文献

Interjurisdictional Competition and Regulatory Advantage 总被引:1,自引:0,他引:1
As formal trade and investment barriers fall, government regulations what once were domestic policy matters becomeissues of international concern. International commerce createsthe potential for competition among regulatory jurisdictions.This article explains why there is variation in these regulatorytrends. Three general trajectories are: (a) convergenceamong countries toward less stringent regulations in some cases,(b) convergence toward more stringent regulations in others,while in still other cases (c) differences persist among countries.I offer three (related) propositions which explain the differentregulatory trajectories: #1) Regulations on production processestend toward laxity; whereas product market-access regulationstend toward stringency. #2) Industrial structure affects thestrength of the process/market-access distinction. Powerfulfirms in concentrated markets facilitate collective action andregulatory capture. Dominant producers push for process andmarket-access regulations which reflect their interests, givingthem a competitive regulatory advantage in world markets. #3)The asset specificity of investments affects regulatory convergence.Low asset specificity leads to a competition-in-laxity; highmultinational asset specificity leads to convergence among jurisdictions(as firms seek to lower their transaction costs); and domesticasset specificity leads to differences among jurisdictions.Detailed case studies (on offshore banking, capital requirements,and infant formula) suggest the propositions are necessary tounderstand general outcomes, although not sufficient to fullyexplain individual cases. 相似文献
