Drug use during pregnancy is an important social and medical issue. Legislatures and courts have offered a variety of responses, ranging from imprisonment to comprehensive service programs that are rehabilitative in nature. This article discusses the prevalence and effects of prenatal drug use, followed by a presentation of the scope of legal responses and treatment options. Some courts do not provide outreach services for drug‐offending mothers, while others may offer a limited range of services. In contrast, a comprehensive justice approach would provide a wide range of health, employment, and social programs for the offender. This approach is based on philosophies of restorative justice, therapeutic jurisprudence, and procedural justice. Such a theory‐based comprehensive justice program ultimately benefits mothers, children, and the community. Considerations are offered for judges who seek to implement a comprehensive justice approach to address this important problem. 相似文献

This paper offers a critical review and reflection of the 1991 University of Iowa shootings. Gang Lu, a disgruntled Iowa graduate student, was initially angered over perceived slights he was receiving from his academic department. When he felt that his concerns were left unanswered by the University, he decided to seek revenge on those whom he felt were responsible. In doing so, he murdered five individuals and paralyzed another before taking his own life. This paper seeks to reflect on these shootings twenty years after the occurrence and to offer a discussion of some of the larger societal themes raised by this tragedy. 相似文献

Identifying group affinity from human crania is a long-standing problem in forensic and physical anthropology. Many craniofacial differences used in forensic skeletal identification are difficult to quantify, although certain measurements of the midfacial skeleton have shown high predictive value for group classifications. This study presents a new method for analyzing midfacial shape variation between different geographic groups. Three-dimensional laser scan models of 90 crania from three populations were used to obtain cross-sectional midfacial contours defined by three standard craniometric landmarks. Elliptic Fourier transforms of the contours were used to extract Fourier coefficients for statistical analysis. After cross-validation, discriminant functions based on the Fourier coefficients provided an average of 86% correct classifications for crania from the three groups. The high rate of accuracy of this method indicates its usefulness for identifying group affinities among human skeletal remains and demonstrates the advantages of digital 3D model-based analysis in forensic research. 相似文献
