Abstract: Criminal acts such as an attack utilizing a radiological dispersal device (RDD or dirty bomb), the manufacture of such a device, or the illicit trafficking of radioactive materials would warrant a criminal investigation. This could involve the collection, transportation, and analysis of radiologically contaminated trace evidence. But are law enforcement agencies and forensic scientists capable of dealing with this? This research investigates the decontamination efficacy of two decontamination techniques (chemical and physical) designed for the removal of radiological material from documents of forensic importance. The impact that these procedures have on the development of latent fingermarks and the forensic analysis of the inks on these documents is also studied. It was found that slight changes in the color and chemical composition of a variety of document inks and a destruction of fingermark ridges occurred after chemical decontamination. Physical decontamination had no impact on these parameters. 相似文献

Abstract: An unexpected infant death is usually investigated with a complete autopsy. If evidence of prior trauma is found at autopsy in these cases, suspicion is raised for nonaccidental trauma. In a young infant, the residua of trauma received during birth has the potential to be incorrectly interpreted as nonaccidental trauma. We report a the findings of a 4 1/2‐month‐old‐infant that died unexpectedly with a healing linear skull fracture and a circular lesion over the calvarium found at autopsy. Though this lesion was concerning, the remainder of the autopsy and the histological findings did not support a diagnosis of recent trauma. Review of the literature describing birth injuries made the diagnosis of healing, residual birth trauma more convincing in this case. 相似文献

Abstract: Continual reports of illicit trafficking incidents involving radioactive materials have prompted authorities to consider the likelihood of forensic evidence being exposed to radiation. In this study, we investigated the ability to recover latent fingermark evidence from a variety of substrates that were exposed to ionizing radiation. Fingermarks deposited on common surfaces, including aluminum, glass, office paper, and plastic, were exposed to doses ranging from 1 to 1000 kGy, in an effort to simulate realistic situations where evidence is exposed to significant doses of radiation from sources used in a criminal act. The fingermarks were processed using routine fingermark detection techniques. With the exception of glass and aluminum substrates, radiolysis had a considerable effect on the quality of the developed fingermarks. The damage to ridge characteristics can, in part, be attributed to chemical interactions between the substrate and the components of the fingermark secretions that react with the detection reagents. 相似文献

Bullying prevention programs in the United States are being implemented in schools from kindergarten through high school to reduce rates of bullying behaviors. The bully prevention in positive behavior support (PBIS) model is an evidence-based, whole school intervention program. The PBIS model trains teachers, school staff, and administrators to model and provide positive reinforcement for children to decrease bullying amongst peers. This article addresses gaps in the current bullying prevention research by exploring challenges and potential modifications to the PBIS model based on staff perspectives of specific student needs. Utilizing focus group methodology, administrators, teachers, and support staff in a northeastern urban elementary school identified challenges experienced by students who were English language learners, impulsive, shy or sensitive, and female. The findings highlight the critical nature of school–parent relationships in addressing student, family, and cultural factors that influence the successful implementation of bullying prevention programs. 相似文献

We explore service worker reactions to a supervisor’s fair treatment of customers (i.e., customer-directed fairness), utilizing the group-value model of fairness to formulate two distinct predictions: (1) a status cuing effect, in which employees internalize social cues from the supervisor’s behavior to determine the social value of customers, and adapting their own customer-oriented behaviors to reflect the supervisor’s cue, and (2) a character indictment effect, in which employees use customer-directed fairness to assess the trustworthiness of the supervisor’s character. Results from experimental and field data provide evidence for these dual effects and show how each ultimately affects the employee’s in-role and extra-role customer service behavior. Implications are discussed with regard to the group-value model of fairness, alternative theories of fairness, and practical applications. 相似文献

The field of law and strategy (LAS) has advanced our understanding of the law's role in competitive advantage. To date, however, LAS has neglected low rule of law environments—countries characterized by expansive degrees of legal uncertainty. LAS should account for these settings, too, since environmental uncertainty is a strategically significant factor for any company. This article situates the strategic relevance of legal uncertainty in the Chinese context and fills an important gap by illustrating how LAS principles apply in low rule of law jurisdictions. Specifically, this article develops the construct of legal entrepreneurship—the notion that attorneys may apply an entrepreneurial mind-set and skill set to position the client favorably and legitimately within the uncertainties of the legal landscape, thereby creating legal competitive advantages for the client. Drawing upon interviews with expert attorneys and executives, this article presents a typology of legal strategies available to U.S. companies in China, uniquely modeling these approaches along the two fundamental dimensions of legal strategy. Additionally, this article identifies two basic types of legal uncertainty in the cross-border context and offers guidelines for the exercise of legal entrepreneurship. Together, these arguments demonstrate that legal entrepreneurship is an empirically viable construct within the LAS project. In low rule of law jurisdictions that have embraced foreign enterprise, legal entrepreneurship will generally optimize the American company's pursuit of both legal value creation and legal risk management. 相似文献

This article investigates how the idea of universal human rights has been co-opted by the prevailing (neo)liberal consensus in support of processes associated with capitalist globalization. So-called “civil and political” rights form the core of (neo)liberal values upon which free market, laissez-faire economics are based, but the idealism of the dichotomy of first and second generation rights is profoundly ideological. Through an examination of the idea of the international citizen, it is argued that the attempt to introduce a duty to promote the widest possible social good falls far short of an obligation to respond to claims for alternative conceptions of “economic and social” rights; far less alternative models of social affairs. Drawing on empirical evidence from Africa, the article contends that the dominance of (neo)liberal rights is integral to the emerging (neo)liberal constitution of the global order effected in the name of “human rights”, “democratization”, “citizenship”, “good governance” and “civil society”.
Never in the recent past have the founding principles of universal rights been so instrumentalized in the service of power, to such an extent that … in the opening years of the twentieth-century, we can speak of a veritable apogee of hegemony and an unprecedented crystallization of the hatreds that it arouses.

Youths transitioning out of detention are particularly in need of support systems that can divert them from recidivism. This article examines the relationship between incarcerated youths' sense of their families' functioning and their perceived likelihood for postdetention success. Despite the control of background variables, results reveal that delinquents who indicated stronger familial functioning also reported a greater likelihood of future success. Although interventions that focus on improving the supportive capacity of families have shown great promise, treatment drop-out rates remain high. To explore incarcerated youths' view of family focused interventions, respondents rated the potential utility of family and nonfamily focused intervention options. A majority of respondents reported that family focused interventions would be helpful. A group of respondents, overrepresented by adolescents with low family functioning, reported that this type of intervention would not be helpful. These results are discussed in terms of their impact on offering family focused interventions for juveniles. 相似文献
