A fresh scientific look at transfer and persistence: From a materials science and tribology perspective

Knowledge of the mechanisms governing transfer, persistence, and recovery of trace evidence, together with background prevalence in the population of interest, and other task relevant information, is key for the forensic interpretation and reconstruction of what happened at the activity level. Up to now, this informational “toolkit” has largely been developed through empirical forensic studies on specific trace materials such as glass, textile fibers, and soil. Combined with the identified systemic siloing between disciplines, while valuable, such research tends to be very material-dependent, introducing specific parameters and interpretations that may have actually impeded the recognition of underlying foundational factors applicable to most material types. In Australia, there has been a renewed interest in developing a discipline-independent framework for the interpretation and/or reconstruction of trace evidence to interpret specific circumstances in casework. In this paper, we present a discipline agnostic “way of thinking” that has been anchored in foundational science underpinning the trace evidence discipline. Physical and mechanical material properties such as material geometry and surface topography, strength, stiffness, and hardness collectively influence contact interactions through underlying friction, wear, and lubrication cause and effect mechanisms. We discuss how these fundamental factors and parameters stemming from materials science and tribology may be adopted and adapted by forensic practitioners and researchers to contribute to a better understanding of transfer, persistence, and recovery mechanisms irrespective of evidence discipline and material type. Examples are provided to demonstrate the practical significance to real-life casework and academic research.     

Rethinking the medical causes of infant death in early modern Europe: a closer look at church registers and medical terminology

The historical roots of the prevailing hypothesis about the main causes of high infant mortality in Europe in the last four centuries are presented in detail focusing on German sources and publications. Assumptions about infections being the main cause of deaths during infancy clearly need to be reevaluated. The terminology of early sources has passed many steps of translation and interpretation. In the old church registers, wording in the local vernacular merely described the most visible symptoms before the final stages of diseases. Scientific medicine and its terminology repeatedly went astray before real pediatric competence was acquired in the nutritional physiology of infants. The combination of different kinds of evidence points to serious flaws in the prevailing hypothesis, while source data and publications confirm a different conclusion: inadequate nutrition due to early weaning and unsuitable substitute food caused the specific set of symptoms described in the historical sources. Medical evidence about infant malnutrition in developing countries supports this new interpretation.     

'Stranger' child-murder: issues relating to causes and controls

Most industrialised countries are concerned with a perceived increase in the killing of children and adolescents by strangers. Though reliable statistics are lacking, the growth of serial murder suggests that more young persons may be at risk than ever before. Explanations, either of a psychological or sociological kind, of child murder by strangers are inadequately developed. Despite the tendency to see such killers as psychiatrically ill a number of studies suggest that the majority of offenders do not differ significantly, at least in psychological traits, from non-offenders. Subcultural and other sociological perspectives stressing "social disadvantage" have low levels of exploratory power and do not assist greatly in understanding child killings. Despite sketchy and contradictory evidence on the effects of the media on sexual and violent crime case study material supports the view that pornography, including popular music, may increase the propensity of individuals to commit atrocities. Counter-measures to control stranger child killing lie in more sophisticated law enforcement (profiling and computer links between police forces) long periods of incarceration of the offender and more sophisticated analyses of the crimes.     

Coping,confidence, and change within the academy: a longitudinal look at police recruits

This study is based on surveys of police recruits representing four agencies across the United States. The recruits were surveyed at the beginning and end of their academy training and asked about coping strategies and the confidence they had in performing their jobs. Coping shifted significantly over time, with recruits utilizing task-oriented and outreach strategies less frequently at the end of the academy than at the beginning. Avoidance coping strategies were used more frequently by recruits at the end of the academy than at the beginning. Slight changes were also found in the influence of these strategies on job confidence over time, with avoidance coping having a stronger influence in the beginning of the academy than at the end. The role of demographic factors on coping was largely invariant over time, with only slight differences detected. Implications for policy and research are also discussed.     

Putting risk factors in their place: an evolutionary-developmental approach to understanding risk

ABSTRACT

The assessment of criminal risk plays a prominent role in the criminal justice systems of many different countries and risk assessment is employed in a number of different domains. Given the importance of risk assessment tools in forensic contexts, and the amount of research devoted to evaluating their accuracy in predicting re-offending, it might be expected that risk assessment tools are grounded in our best theoretical understanding of the causal processes that give rise to criminal actions. However, it is not at all clear that this is the case. In this article, I will argue that one important area of neglect is the failure to fully engage with the literature in developmental and life-course criminology which also has directed an enormous amount of effort in to identifying risk factors for offending. At the heart of this neglect, I will claim, is the failure to fully recognise the key distinction between predicting offending and predicting re-offending. I will further argue that an evolutionary developmental perspective provides the theoretical resources to provide fully explanatory accounts of offending and re-offending, and in which risk factors can be appropriately located. I conclude by briefly considering some implications for theory, research, and practice.

First do no harm: a look at correctional policies and programs today

Objectives

This paper reviews the historical changes in correctional policies and the impact these changes have had on the operations of corrections and correctional programs. Social changes and theoretical perspectives moved corrections away from a focus on rehabilitation to programs characterized by deterrence, incapacitation, and control. Similarly, theoretical criminology encouraged corrections to move away from rehabilitation towards programs designed to provide social opportunities such as employment and housing for offenders. This paper examines whether these changes in policies and programs have been effective in reducing recidivism. The question is: What works in corrections?

Methods

This paper reviews the research examining the impact of correctional policies and programs on the later criminal activities of offenders and delinquents. Research using systematic reviews, meta-analyses, and the Maryland method scores is used to draw conclusions about the effectiveness of various types of programs, management strategies, and policies.

Results

Research demonstrates programs based on deterrence, incapacitation and increased control do not reduce the future criminal activities of offenders and delinquents. Nor have programs targeting social opportunities such as employment and housing been effective in reducing recidivism. The most effective programs target individual-level change in thinking and information processing.

Conclusions

In the search for ways to sanction offenders, U.S. correctional policies and programs using control, deterrence, and incapacitation have harmed individuals and communities. Such programs have not been effective in reducing recidivism. While programs that provide social opportunities for offenders do not necessarily harm offenders neither do they decrease later criminal activities. Effective programs bring about a cognitive transformation in offenders and delinquents. Theorists have begun to develop hypotheses about how and why these transformations are effective. The current emphasis on evidence-based programs, the research evidence on what is effective and the need to reduce the cost of corrections suggest we are on the brink of another paradigm change. Where this will take us is still unclear, but the paradigm will have to address the current problems facing the U.S. correctional systems.     

Race matters: A critical look at racial profiling, it's a matter for the courts

The disproportionate number of minority motorists stopped by the police gives rise to a host of salient questions which center on contemporary police practices. Research has shown that traffic stops are routinely used as a “pretext” to stop minority drivers. In this article, the authors argue that the current police practice of disproportionately stopping minority motorists was formally sanctioned by the Supreme Court in Whren v. United States (1996). The current thrust to examine police practices will do little to end racial profiling, and the underpinnings of this problem, in part, lie in judicial precedent. The authors present the notion that in order to minimize racial profiling, the court must carve out an objective test from the Whren decision that will guide police behavior in the pretextual stops of motorists. The article concludes with a template of what this objective test may look like.     

Community participation in the certificate-of-need process: a look at ten-taxpayer groups in Massachusetts

Certificate-of-need statutes give designated state agencies veto power over investment in health care facilities. Some states have sought to temper the arbitrary character of this power by expanding the opportunities for community input into the certificate-of-need process. Massachusetts, for example, has enacted a statute that allows groups of ten taxpayers to petition for a public hearing on any certificate-of-need application. Some observers question whether the benefits of taxpayer-group participation are substantial enough to compensate for the delays and abuses that the statute allegedly invites. To help resolve this question, this Comment examines historical data on Massachusetts taxpayer groups and on their activities and assesses the significance of their composition and tactics to the certificate-of-need process. Although flaws exist in the Massachusetts ten-taxpayer mechanism, in this writer's view it has succeeded partially in making the certificate-of-need process responsive to community opinion. Many groups lack the skills and qualities needed to make constructive use of the ten-taxpayer mechanism. Nevertheless, it serves a valuable purpose by creating a public forum for and by encouraging public participation in the certificate-of-need process, especially by those who might otherwise try to circumvent that process through use of special legislation, of private pressure, or of other similar means.     

Victim/witness noncooperation: A second look at a persistent phenomenon

During the last decade, numerous programs were established to increase the alarmingly low rate of cooperation of victim/witnesses with lower criminal court officials. It is argued that these programs were largely unsuccessful because they were based on assumptions about the motives of victim/witnesses and about the effect of their cooperation on case outcomes which were only partially correct. The article attempts to explain noncooperation by integrating what is known about the desires and expectations of victim/witnesses from recent empirical studies with what is known about the nature of the adjudication process from organizational studies of criminal courts. The article concludes that victim/witness noncooperation may not pose the major obstacle to prosecution that has been alleged, but that it is indicative of the failure of criminal courts to recognize that victim/witnesses have a legitimate interest in the adjudication process.
