It is not uncommon for there to be multiple eyewitnesses to a crime, each of whom is later shown a lineup. How is the probative value, or diagnosticity, of such multiple-witness identifications to be evaluated? Previous treatments have focused on the diagnosticity of a single eyewitness’s response to a lineup (Wells and Lindsay, Psychol. Bull. 3 (1980) 776); however, the results of eyewitness identification experiments indicate that the responses of multiple independent witnesses may often be inconsistent. The present paper calculates response diagnosticity for multiple witnesses and shows how diagnostic probabilities change across various combinations of consistent and inconsistent witness responses. Multiple-witness diagnosticity is examined across variation in the conditions of observation, lineup composition, and lineup presentation. In general, the diagnostic probabilities of guilt were shown to increase with the addition of suspect identifications and decrease with the addition of nonidentifications. Foil identification results were more complicated-diagnostic of innocence in many cases, but nondiagnostic or diagnostic of innocence in biased lineups. These analyses illustrate the importance of securing clear records of all witness responses, rather than myopically focusing on the witness who identified the suspect while ignoring those witnesses who did not.  相似文献

The National Institute on Drug Abuse has observed an increase in fentanyl deaths in the United States. One epidemic related to the abuse of fentanyl happened in Cook County in 2005–2007 (350 deaths). Another outbreak of fentanyl deaths occurred in 2015–2017 in the same area. The database of the Cook County Medical Examiner's Office was searched for cases of fentanyl deaths between 2015 and 2017: 1244 deaths were found. A comparison was performed with the previous data: an increase in the number of females was observed in 2015–2017. Also, in 2005–2007, the majority of deaths occurred among African American, while in 2015–2017, Caucasians were more involved. Within our population, some drug combinations were more common in specific demographic subgroups (male/females; Caucasian/African American; and certain age groups). The epidemiology and the most significant drug associations found at the toxicology are discussed, highlighting the usefulness of the knowledge about this outbreak for public health.  相似文献

Objectives

Begun in 1939, the Cambridge-Somerville Youth Study (CSYS) is recognized as the first delinquency prevention experiment and the earliest example of a longitudinal–experimental study with criminological outcomes. This paper aims to develop a historical understanding of the origins of the study’s research design.

Methods

The present study is guided by the socio-historical approach and informed by past historical research in criminology. It draws upon a wide array of archival records and published works from the late nineteenth century to the present day.

Results

Richard Clarke Cabot designed and directed the CSYS. Major influences on the study’s research design can be traced to Cabot’s medical practice and research, his advocacy for social work practice and research, and his professional relationship with the Gluecks. The beginnings of experimentation in the social sciences during the early twentieth century may have also played a role. Joan McCord’s early involvement in the study proved instrumental to its longitudinal component.

Conclusions

The rigorous and innovative research design of the CSYS marks an important chapter in the history of experimental criminology, and its influence continues to this day. New experimental studies on the prevention of crime and delinquency must continue to strive to advance scientific knowledge and improve public policy.

In recent decades, the number of juvenile defendants transferred to criminal court has increased dramatically, in large measure due to an expansion of available transfer mechanisms. While transfer traditionally occurred by judicial waiver of jurisdiction, alternatives have emerged and eclipsed judicial waiver as the primary route to adult court. The present study examines whether the mechanism of waiver—judicial, prosecutorial, or legislative—affects sentencing outcomes for juvenile defendants transferred to adult court. Results from multilevel models that control for state-level variation indicate that sentencing outcomes are inextricably tied to method of transfer. Most notably, non-criminal outcomes are most likely for cases that arrive in criminal court by legislative waiver. This suggests that legislative waiver is an ineffective means of sending juvenile offenders to criminal court, and provides some empirical support for the notion that judicial waiver is the most appropriate method of transfer.  相似文献

English research on protoindustrial communities in general and the protoindustrial family in particular has fallen somewhat behind that in many continental countries. Constrained by inadequate sources and a historiographical literature that has constantly placed the small and simple nuclear unit at the heart of English residential arrangements, English historians have often seen the protoindustrial family as little different in form and function from those to be observed in rural areas or market towns. This article uses sources generated by the English poor law to offer different perspectives. Focusing on Lancashire, as the protoindustrial phase of its development began to truly break down in the early 19th century, the article suggests that the English protoindustrial family was volatile in form and size and that the nature of underlying protoindustrial demography and the communal welfare system provided a powerful impetus to a process that saw the constant redistribution of kin between related households. It concludes that in Lancashire the expectation among protoindustrial families must have been volatility and that complex families rather than simple nuclear families have long held the English imagination.  相似文献

The legal aid movement started from the notion of social action. Today, legal aid constitutes a highly commodified field that continues to be dominated by jurists and lawyers. For this reason, the kind of critical reflection that already exists in social work is also required in relation to the notion of legal aid as envisaged by the legal aid movement. Justiciable problems necessarily manifest themselves in a social context. An evolving community, faced with increasingly complex issues, demands a multidisciplinary approach, as it becomes clear that the traditionally deterministic view of professions ought to be abandoned. A ‘socially responsible legal aid system’ therefore presupposes that various disciplines should mutually influence one another. Hence, the jurist and the social worker should not only work side by side, but they should also collaborate and mutually enhance one another's activities and approaches. There is a need for an overarching holistic approach that can reassert the legitimacy of legal aid. Looking at legal aid services in Belgium, one may conclude that a critical reflexive attitude on the part of current legal aid providers is crucial for attaining an effective socially responsible legal aid practice that stretches across the boundaries of different professional groups.  相似文献
