ABSTRACT

Since the late 20th century, the federal government has regulated colleges’ and universities’ handling of campus sexual and gender-based violence (CSGBV). Although the arc of history has bent toward establishing greater protections for victims of such violence, new proposed regulation by the U.S. Department of Education under the Trump administration focuses more heavily on ensuring due process rights for students accused of CSGBV. Most recently, in November 2018, U.S. Secretary of Education, Betsy DeVos submitted a proposed rule change to the regulation of Title IX of the Education Amendments of 1972. This article provides the historical context for this most recent proposed federal regulation of CSGBV and discusses the criticism of this proposal that, if it is implemented, students would become less safe in the ivory tower.  相似文献

Several studies had concluded that the police subculture holds values and attitudes that are distinct from the rest of the population. Among these values is a focus on law and order. While researchers agree that police tend to hold different values, they disagree on the source of the attitudes. Some had argued that the attitudes reflected differences regarding who was recruited for law enforcement careers while others said that the differences reflected changes that occurred to individuals after becoming officers. This study examined whether police officers and students enrolled in criminal justice/sociology classes held similar or different attitudes towards the Miranda warnings. The findings suggested that in some ways, the two groups perceived the warnings in dramatically different ways, while in other ways their differences were simply a matter of degree. Implications are provided.  相似文献

The present study measured the existence of traumatic stress symptomatology as reported by certified law enforcement officers within the State of Delaware. A questionnaire was devised which documented age, sex, race, education, years of service, marital status, children, rank, position, and shift work. The questionnaire was divided into parts which assessed the exposure and the frequency of specific traumatic incidents experienced in the line of duty, and the frequency of experienced traumatic symptomatology criteria: re-experiencing, numbing, and arousal.  相似文献

This study aimed to expand the scope of previous research by assessing the effectiveness of soot-removal techniques on glass from petrol-bomb debris using methods of 1% and 2% sodium hydroxide (NaOH) solutions, ultrasonic bath and vacuum suction. Of particular interest were the 1% and 2% NaOH solutions applied to the soot-covered surfaces. Petrol bombs containing petrol or a 50:50 mix of petrol and motor oil were exploded and the debris was collected for analysis. Favourable results were found to varying degrees using each of the soot-removal methods with the 1% and 2% NaOH wash solutions, being the most useful. The 2% NaOH solution also proved successful as a soak to loosen and remove heavy contamination of soot and accelerants without damaging the finger mark beneath. This study also found that recovery of finger marks in blood from beneath soot using the 2% NaOH solution was possible. Finger marks were also applied to glass bottles with plastic adhesive labels, and providing the fire damage is not too great marks were also retrievable. Results from this study lead to the conclusion that the NaOH wash solution is ideally suited for soot removal to reveal latent and blood-contaminated marks both within the laboratory and at crime scenes.  相似文献
