Evaluation of different sampling media for their potential use as a combined swab for the collection of both organic and inorganic explosive residues

Commercially available skin cleansing alcohol wipes and conventional swabs were investigated for their use as a universal sampling medium for the simultaneous collection of both organic and inorganic explosive residues. Six compounds with the potential to be encountered in casework [pentaerythritol tetranitrate (PETN), 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), triacetone triperoxide (TATP), ammonium nitrate, and sodium chlorate] were selected as representative target compounds. Quantities of these target compounds were deposited on four different substrates (glass, plastic, aluminium foil and laminate). Two chosen alcohol wipes demonstrated better overall performance in the recovery of both the organic and inorganic representative compounds from each of the test surfaces compared to the results obtained using conventional cotton and polyester swabs, pre-moistened with various solvents, and a direct methanol wash (used as a control). Results obtained using dry cotton swabs indicated that it was not an effective swabbing system for the collection of both organic and inorganic explosive residues on common substrates.     

Estimation of stature from static and dynamic footprints

The ability to estimate accurately from known parameters is a fundamental aspect of science and is evident as an emerging approach in the area of footprints and stature estimation within the field of forensic identification. There are numerous foot dimensions that have been measured in the literature to predict stature with varying degrees of confidence but few studies have tried to link the strength of estimation to anatomical landmarks. Such an approach is utilised in this study which estimates stature from the right footprints of sixty one adult male and female UK participants. Static and dynamic footprints were taken from each volunteer using the 'inkless paper system'. The prints were digitised and twelve length, width and angle measurements were chosen for the analysis. The highest correlations with stature were shown to be the heel to fourth toe print for the static group of footprints (r=0.786, p<0.01), and the heel to fifth toe print in the dynamic footprints (r=0.858, p<0.01). Collinearity statistics suggest the heel to fifth toe print length measurement is independent and not influenced by any other variables in the estimation of stature for the dynamic prints. Linear regression equations for this measurement presented the smallest standard error of estimate (SEE) and highest shared variance (R(2)) of all included variables (SEE 4.16, R(2) 0.74). Our study discusses a potential anatomical explanation as to why the lateral border of the foot and hence the impression it makes upon a hard surface, is a more stable indicator in the estimation of stature. The investigation recommends the use of Calc_A4 and Calc_A5 length measurements when estimating stature from footprint impressions.     

Recent Iowa trends in sudden unexpected infant deaths: the importance of public health collaboration with medical examiners' offices

During the winter in 2008, Iowa experienced an increase in sudden unexplained infant deaths (SUIDs). SUIDs and infectious causes of infant deaths generally average 3 monthly (SD = 1.0) in Iowa. However, in January 2008, 9 infant deaths were reported to the Iowa Department of Public Health and the Iowa Office of the State Medical Examiner. Between January and March of 2008, joint investigation of 22 SUIDs was conducted. The investigations required the involvement of multiple medical examiners from various jurisdictions, testing for pathogens at the University Hygienic Laboratory, epidemiologic support from the Iowa Department of Public Health, and consultation with the Centers for Disease Control and Prevention. The preliminary hypotheses for the increase in the infant mortality included viral respiratory disease and/or possible novel respiratory viral infections being the cause. Collaboration between public health and the medical examiner offices resulted in timely assessment of the cases. While no single causative agent was responsible for the increase seen in the number of infant deaths, respiratory pathogens played a role in the deaths of 15 of 22 children.     

Fairness in Animals: Where to from Here?

In the last decade, there has been an explosion of work investigating non-human species?? behavior as it relates to the human sense of fairness and justice. This research has provided a much needed evolutionary perspective on humans, and highlighted ways in which humans?? behavior is both similar to and different from that of other species. In this concluding paper, we outline the major threads of the work highlighted in this and the previous special issues of Social Justice Research and provide thoughts on future directions for the field. This is a very exciting time in our exploration of the evolution of human justice and fairness, and we eagerly await the developments of the next decade.     

Party unity and presidential dominance: parliamentary development in the fourth republic of Ghana

Political power in contemporary sub-Saharan Africa is often portrayed as being highly informal and heavily personalised. The assumption that personalised politics is how ‘Africa works’ has led to the neglect of the study of Africa's formal institutions, including parliaments. This article assesses the position of the Parliament of Ghana under the Fourth Republic. It displays evidence suggesting that over successive parliamentary terms parliamentary committees became increasingly adept at handling legislation, and inputting into the policy process. It also shows that the parliament was increasingly able to oversee the implementation of legislation. Although the findings of hitherto undocumented progress represent a valuable nuance, the argument that the parliament became increasingly able to input into the legislative process says exactly that; while the parliament became increasingly capable of amending legislation rarely was this witnessed. The article argues that parliamentary development in Ghana has been a function of three interacting structural factors: the constitution; unified government since 1992; and political party unity. The strong partisan identities of legislators from the two major political parties – the New Patriotic Party (NPP) and National Democratic Congress (NDC) – provide the executive with extra leverage to control the parliament. Throughout the Ghanaian parliament is juxtaposed with the Kenyan National Assembly. More substantially, the article seeks to force a revision of the dominant narrative that generalises African party systems as fluid and fragmented, and African political parties as lacking any recognisable internal cohesion or ideology.     

Prediction of adolescent sexual reoffending: A meta-analysis of the J-SOAP-II, ERASOR, J-SORRAT-II, and Static-99

Several risk assessment tools, including the Juvenile Sex Offender Assessment Protocol-II (Prentky & Righthand, 2003), the Estimate of Risk of Adolescent Sexual Offense Recidivism (Worling & Curwen, 2001), the Juvenile Sexual Offense Recidivism Risk Assessment Tool-II (Epperson, Ralston, Fowers, DeWitt, & Gore, 2006), and the Static-99 (Hanson & Thornton, 1999), have been used to assess reoffense risk among adolescents who have committed sexual offenses. Given that research on these tools has yielded somewhat mixed results, we empirically synthesized 33 published and unpublished studies involving 6,196 male adolescents who had committed a sexual offense. We conducted two separate meta-analyses, first with correlations and then with areas under the receiver operating characteristic curve (AUCs). Total scores on each of the tools significantly predicted sexual reoffending, with aggregated correlations ranging from .12 to .20 and aggregated AUC scores ranging from .64 to .67. However, in many cases heterogeneity across studies was moderate to high. There were no significant differences between tools, and although the Static-99 was developed for adults, it achieved similar results as the adolescent tools. Results are compared to other meta-analyses of risk tools used in the area of violence risk assessment and in other fields. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Procedural justice, routine encounters and citizen perceptions of police: main findings from the Queensland Community Engagement Trial (QCET)

Objectives

To test, under randomized field trial conditions, the impact of police using the principles of procedural justice during routine encounters with citizens on attitudes towards drink-driving, perceptions of compliance, and their satisfaction with the police.

Methods

We conducted the first randomized field trial??the ??Queensland Community Engagement Trial?? (QCET)??to test the impact of police engaging with citizens by operationalizing the key ingredients of procedural justice (neutrality, citizen participation, respect, and trustworthy motives) in a short, high-volume police?Ccitizen encounter. We randomly allocated 60 roadside Random Breath Testing (RBT) operations to control (business-as-usual) and experimental (procedural justice) conditions. Driver surveys were used to measure the key outcomes: attitudes towards drinking and driving, satisfaction with police and perceptions of compliance.

Results

Citizen perceptions of the encounter revealed that the experimental treatment was delivered as planned. We also found significant differences between the experimental and control groups on all key outcome measures: drivers who received the experimental RBT encounter were 1.24 times more likely to report that their views on drinking and driving had changed than the control group; experimental respondents reported small but higher levels of compliance (d?=?.07) and satisfaction (d?=?.18) with police during the encounter than did their control group counterparts.

Conclusions

Our results show that the way citizens perceive the police can be influenced by the way in which police interact with citizens during routine encounters, and demonstrate the positive benefits of police using the principles of procedural justice. Our study was limited by the use of paper-only surveys and low response rate. We also recognize that the experiment setting (RBT road blocks) is limiting and non-reflective of the wider set of routine police?Ccitizen encounters. Future research should be undertaken, using experimental methods, to replicate our field operationalization of procedural justice in different types of police?Ccitizen encounters.     

Can Saying Something Make It So? The Nature Of Seditious Harm

In this paper, I redress an analytic deficit in debates about sedition by providing an explanatorily account of the relation between speech and action using speech act theory as developed by J.L. Austin. The specific focus will be on speech acts advocating violence against the state, in the form of religious sermons preaching violent jihad or glorifying acts of terrorism. This philosophical account will have legal consequences for how we classify speech acts deemed to be dangerous, or to cause harm. It also suggests that because speech can constitute action or conduct in certain circumstances, sedition laws, in principle, might be defensible, but not in their current form.     

A Genealogy: Tracing the Origins of Museum Admission Charges

Using Jim Scheurich's “Policy Archeology” as a theoretical framework, a genealogy of museum admission charges in the United States is presented. The three factors that ultimately led to the implementation and expansion of charges are the income/expenses balance, isomorphism within the museum field, and the philosophical stance of museums regarding the public purpose of the institution. These factors are tracked from early museum history through the 1980s, when admission charges become a new norm in the field.
