In addition to having blast mitigation properties, aqueous foam concentrate AFC-380 blast suppression foam is designed to capture aerosolized chemical, biological, and radioactive particles during render-safe procedures of explosive devices. Exposure to aqueous environments and surfactants may negatively affect forensic evidence found at the scene, but the effects of AFC-380 foam and aqueous gel on the preservation and subsequent analysis of forensic evidence have not previously been investigated. Sebaceous finger and palm prints and DNA samples on paper, cardboard, tape, and various metal and plastic items, along with hairs, carpet and yarn fibers, and inks and documents, were exposed to AFC-380 foam. Similar mock evidence was also exposed to a superabsorbent gel of the type found in aqueous gel blocks used for shrapnel containment. Exposure to foam or aqueous gel was associated with a dilution effect for recovered DNA samples, but quality of the samples was not substantially affected. In contrast, exposure to AFC-380 foam or gel was detrimental to development of latent finger and palm prints on any substrate. Neither the hair nor the fiber samples were affected by exposure to either the foam or gel. Indented writing on the document samples was detrimentally affected by foam or gel exposure, but not inks and toners. The results from this study indicate that most types of forensic evidence recovered after being exposed to aqueous gel or blast suppression foam can be reliably analyzed, but latent finger and palm prints may be adversely affected.  相似文献

ABSTRACT

When confessions are entered into evidence in criminal courts, issues of coercion and voluntariness are important and often contested matters. Occasionally, defense attorneys proffer expert witnesses to testify about the coercive pressures of an interrogation and the risk of a false confession. Such testimony is often ruled inadmissible on the grounds that it does not inform the jury beyond its common knowledge. In our effort to test this judicial assumption about common knowledge, we surveyed jury-eligible laypeople (n?=?67) and social scientists specializing in interrogation and confessions (n?=?54) regarding their opinions about the coerciveness of prohibited interrogation tactics, maximization techniques, minimization techniques, and suspect risk factors and compared their ratings with a set of independent t tests. Laypeople gave lower ratings to the coerciveness of all sets of items representing interrogation techniques, and lower ratings to the vulnerabilities associated with suspect risk factors, as compared to social science experts. The disparities between laypeople’s and experts’ perceptions of coercion in interrogations demonstrate that such issues are not fully within the common knowledge of prospective jurors, and suggest the need to provide jurors with expert witness guidance when tasked with evaluating confession evidence.  相似文献

Regulation increasingly mandates collaborative approaches to increase stakeholder input and streamline approval processes. However, understanding how to maintain stakeholder involvement over the course of a long collaborative process is vital to optimize effectiveness. This paper observes more than 700 stakeholders involved in developing and implementing a dam operating license over 16 years. We use text mining and Bayesian hierarchical modeling to observe meeting attendance and recorded actions in meeting minutes. We find that involvement decreased after the initial planning phase, but steadily increased through license development and implementation. After the regulatory mandate to consult with external stakeholders dissolved, overall attendance declined while attendance stability increased, meaning that the non‐mandatory stage involved a smaller cadre of dedicated actors. This indicates that high‐performing mandated stakeholder involvement processes rely on a constrained group of conveners to sustain interaction and have less turnover than what might be expected given existing evidence from grassroots involvement; assumptions about group dynamics based on involvement in grassroots processes may lead to improper predictions about who will participate, and how, in processes where stakeholder involvement is mandated.  相似文献

The opposition of American liberals to the Vietnam War has often been seen as suspect by historians who compare their actions and positions unfavorably with the passionate dissent of the New Left and its straightforward call for the unilateral withdrawal of U.S. military forces from Southeast Asia. This article argues that when it is evaluated on its own merits, the antiwar activism of prominent liberals from the Americans for Democratic Action (ADA) does not represent a less “pure” version of the dissent mounted by the New Left, but a dedicated, if less than effective, opposition to U.S. military intervention in a distant civil war. By making room for liberals—both within and outside of the ADA—in the antiwar movement, we gain a more complete picture of both postwar liberalism and the complex dynamics of the largest antiwar movement in American history.  相似文献

Although brain imaging has recently taken center stage in criminal legal proceedings, little is known about how neuroscience information differentially affects people’s judgments about criminal behavior. In two studies of community participants (N = 1161), we examined how mock jurors sentence a fictional psychopathic defendant when presented with neurological or psychological research of equal or ambiguous scientific validity. Across two studies, we (a) found that including images of the brain did not alter mock jurors’ sentencing judgments, (b) reported two striking non-replications of previous findings that mock jurors recommend less severe punishments to defendants when a neuroscientific explanations are proffered, and (c) found that participants rated a psychopathic individual as more likely to benefit from treatment and less dangerous when a neurological explanation for his deficits was provided. Overall, these results suggest that neuroscience information provided by psychiatrists in hypothetical criminal situations may not broadly transform mock jurors’ intuitions about a psychopathic defendant’s sentence, but they provide novel evidence that brain-based information may influence people’s judgments about treatability and dangerousness.  相似文献

When the Criminal Justice System adjudicates an individual felony offender, it complicates many aspects of that individual's life; from applying for colleges, and jobs to attempting to become contributing member of society. In New York, to prevent seven‐ to sixteen‐year‐old youth who commit felony offenses from becoming felony offenders, the courts prosecute them as juvenile delinquents or juvenile offenders. In the United States, individuals under the age of twenty‐one cannot purchase alcohol or tobacco and cannot get married without parental consent, but they can be charged with a felony. Before and even after reaching the age of twenty‐one, individuals are still in need of guidance, support, education, employment, and stability as brain development is still ongoing. To help protect those who have not reached the age of twenty‐one, states should implement Senior Youthful Offender Hearings as proposed in this Note. This hearing is a two‐part hearing: (1) determine if an individual should be considered eligible for the protections under the current Youthful Offender Laws and (2) determine sentencing and alternatives to incarceration, focused on steering Senior Youthful Offenders on the right path.  相似文献

Since the development of the striagraph, various attempts have been made to enhance forensic investigation through the use of measuring and imaging equipment. This study describes the development of a prototype system employing an easy‐to‐use software interface designed to provide forensic examiners with the ability to measure topography of a toolmarked surface and then conduct various comparisons using a statistical algorithm. Acquisition of the data is carried out using a portable 3D optical profilometer, and comparison of the resulting data files is made using software named “MANTIS” (Mark and Tool Inspection Suite). The system has been tested on laboratory‐produced markings that include fully striated marks (e.g., screwdriver markings), quasistriated markings produced by shear‐cut pliers, impression marks left by chisels, rifling marks on bullets, and cut marks produced by knives. Using the system, an examiner has the potential to (i) visually compare two toolmarked surfaces in a manner similar to a comparison microscope and (ii) use the quantitative information embedded within the acquired data to obtain an objective statistical comparison of the data files. This study shows that, based on the results from laboratory samples, the system has great potential for aiding examiners in conducting comparisons of toolmarks.  相似文献

In Lent Term 1668/9, John Vincent, a bencher of Gray’s Inn, gave a reading on the Merchants’ Assurances Act 1601 (43 Eliz. I, c.12). The notes of the law reporter, Joseph Keble, record this observance of the centuries-old tradition of readings, which was destined to expire within the next two decades. This paper situates Vincent’s reading within the changing tradition of readings in the seventeenth century. It highlights the role readings continued to play in disseminating sophisticated legal learning, particularly in relation to newer areas of practice such as marine insurance, which were largely uninformed by statute, common law precedent or reference works, and would have been difficult to master through book-study alone. It examines a selection of issues discussed during the reading, focussing on legal outcomes grounded in the ‘customs’, usages, practices and understandings of merchants, and illustrating how these were perceived as exceptional by comparison to the ordinary rules of the common law. The nature and jurisdiction of London’s court of assurances, reconstituted and empowered by the 1601 Act, are also discussed. More generally, this paper demonstrates the value of post-Restoration readings for historians of English law in the late seventeenth century.  相似文献
