A novel FTA™ elute card collection method that improves direct DNA amplification from bloodstained concrete

Concrete is a common construction material found in residential and commercial buildings, bridges and parking lots that is a composite matrix containing aggregate held together with cement. The porous nature of concrete can make the collection and genotyping of biological fluids, such as blood, challenging. Forensic evidence can become embedded within the matrix, potentially reducing the amount of DNA available for analysis. In forensic science, “direct” amplification refers to a genotyping method that amplifies a DNA profile directly from a sample without DNA extraction, saving time and money. We investigated a novel application of Whatman? FTA? Elute cards in their ability to directly amplify PowerPlex® Fusion and Y23 profiles from minute amounts of blood that had been deposited on different concrete structures. In comparison to traditional collection methods, directly profiling blood stained construction materials using FTA? Elute cards increased the percentage loci amplified and significantly improved both allele peak height and peak height ratio while reducing allelic drop-out. FTA? Elute cards can provide a reliable, inexpensive and superior alternative to traditional methods.     

A Perspective on Errors,Bias, and Interpretation in the Forensic Sciences and Direction for Continuing Advancement*

Abstract: The forensic sciences are under review more so than ever before. Such review is necessary and healthy and should be a continuous process. It identifies areas for improvement in quality practices and services. The issues surrounding error, i.e., measurement error, human error, contextual bias, and confirmatory bias, and interpretation are discussed. Infrastructure is already in place to support reliability. However, more definition and clarity of terms and interpretation would facilitate communication and understanding. Material improvement across the disciplines should be sought through national programs in education and training, focused on science, the scientific method, statistics, and ethics. To provide direction for advancing the forensic sciences a list of recommendations ranging from further documentation to new research and validation to education and to accreditation is provided for consideration. The list is a starting point for discussion that could foster further thought and input in developing an overarching strategic plan for enhancing the forensic sciences.     

Examining the Incidence of and Time to Recidivism Within the Risk Contingency Framework: A 20-Year Follow up Study

This study examined the extent to which the contingencies risk framework (consisting of dispositional, historical, contextual, and clinical domains) predicted detected recidivism (i.e., arrest or conviction). Secondary data were extracted on 413 prisoners who underwent a psychiatric evaluation, were assessed on the risk domains, and followed up over 20 years. There were 273 (66.1%) cases of recidivism for serious offenses (e.g., assaults). Criminal career outcomes examined included: years to and the incidence of recidivism. Statistics showed that chance classification of the incidence of recidivism was 21% more accurate for the recursive partitioning than the bilinear model. These results are consistent with the contingencies risk framework, support its use over linear models, and highlight its predictive utility.     

Correlativity

In a celebrated article, published nearly a century ago, Wesley Newcomb Hohfeld endeavored to elucidate the various types of jural relations. Hohfeld’s scheme has been justly regarded as a seminal contribution to analytical jurisprudence, and has stimulated lively debate since. This Essay aims to refute one of Hohfeld’s fundamental and most influential theses: the axiom of right–duty correlativity. To do so, it employs the simplest refutation strategy in first-order logic, namely providing a valid counterexample. Part I discusses earlier attempts to do likewise, and explains why they failed. For the most part, previous illustrations of ostensibly standalone rights or standalone duties neglected relevant parties who could owe the correlative duties or hold the correlative rights, respectively. Part II puts forward a simple argument: There are abstract duties in private law that ban certain types of conduct without reference to specific victims. Those duties are not necessarily correlative with rights, although their breach may generate secondary duties with corresponding rights. In particular, tort law allows plaintiffs to recover for harm caused by breach of duty that occurred before they acquired legal personality. This is tantamount to recognizing duties that are not correlative with rights, and therefore invalidates the correlativity axiom.     

A new psychometric instrument assessing vulnerability to risk of suicide and self-harm behaviour in offenders: Suicide Concerns for Offenders in Prison Environment (SCOPE)

This study aimed to develop a new psychometric instrument to assess vulnerability to risk of suicide and nonfatal self-harm behaviour in young adult male and female offenders. In total three studies were conducted to assess the psychometric properties of the new instrument using both exploratory and confirmatory factor analysis in different samples. Participants in all three studies included a total of 1,166 young adult offenders across six Her Majesty's Prisons. The new instrument, Suicide Concerns for Offenders in Prison Environment (SCOPE), contained 28 items scoring on two subscales. The factorial structure of the new instrument initially obtained with exploratory factor analysis was subsequently confirmed in a new sample. The internal consistency of the two subscales were acceptable but the test-retest reliability coefficients were moderate. Concurrent validation with the Beck Hopelessness Scale was acceptable and SCOPE showed the ability to discriminate between those at risk and those with no known history of attempted suicide and nonfatal self-harm behaviour ( p < 0.01).     

Exposure to Intimate Partner Violence Amongst Women of Reproductive Age in Lagos,Nigeria: Prevalence and Predictors

Research on predictors of Intimate Partner Violence (IPV) in Sub-Saharan Africa is contradictory, necessitating further investigation. This study sought the prevalence and predictors of IPV among women in Lagos, Nigeria. Questionnaire data from 934 women visiting an obstetrics and gynecology clinic in Lagos were analyzed using multivariable methods. The 1 year prevalence of IPV was 29%, with significant proportions reporting psychological (23%), physical (9%) and sexual (8%) abuse. In-access to information, women’s autonomy and contribution to household expenses independently predicted IPV. The findings provide new incites for IPV prevention in Lagos with implications for further research.     

Max Weber, Socialism, and the Space for Time

In Economy and Society Weber provides a detailed criticism of socialism emphasizing the dynamic nature of the formal rationality of economic action, thus indicating the limits of bureaucratic rationality. Unfortunately, Weber's critique has received scant attention, commentators concentrating instead on remarks in his political essays. Weber's main argument against socialism is that it would lead to a decrease in formal rationality. Drawing upon Austrian political economy, Weber attempts to secure a 'realm of freedom' within anarchical capitalist production through emphasizing the dynamic nature of economic decision making which necessarily precludes the possibility of a rational socialist planned economy.     

The Past,Present, and Future of Mediation as Seen through the Eyes of Some of Its Founders

This article is drawn from interviews with thirty‐one of mediation's “founders,” those pioneers who began mediating in the 1970s and 1980s, when the field was young. They describe what first attracted them to mediation and why they have remained active in the field. Some told us that they have found it to be both intellectually challenging and interpersonally satisfying to assist disputing parties in their search for a mutually acceptable resolution they could not find on their own. Others see mediation's collaborative approach to decision making as a means of bringing about social and political change that might be otherwise unattainable. The mediators also described the changes they have observed since they entered the field: mediation's dramatic growth, institutionalization in the judicial system, and market domination by lawyers and retired judges. Among the concerns they expressed were the prevalence of a mediation model that focuses primarily on the legal strengths and weaknesses of each party's position, and the dollar amount that should resolve the dispute, with little interest in creative outcomes. Other concerns are a lack of quality control of mediators and trainers, and unproductive debate about whether the “correct” approach to mediation is evaluative, facilitative, or transformative. The mediators who work on public policy matters, including environmental disputes, were the most positive about the opportunity for creativity in their work, considerably more so than those mediators whose practice is primarily business/commercial. The mediators' views of the future of mediation are remarkably similar — their general sense is that the type of mediation that takes place in the shadow of the courts is likely to increase and to become even more routinized than it is at present. Several respondents told us that they also expect to see substantial growth in the use of mediation to resolve public policy issues. Many of these mediators predicted that this type of mediation is likely to be carried out by organizational insiders, rather than outside interveners. As one mediator said, “Maybe there's a new set of mediation roles for people within traditional institutions, not just for free‐standing neutrals.”
