Applying the Theory of Reasoned Action to Domestic Violence Reporting Behavior: The Role of Sex and Victimization

Domestic violence is a serious social issue that affects one in every four relationships. Interventions for victims and abusers are contingent upon reporting of the violence, but many cases are never reported. The theory of reasoned action may offer a model for understanding reporting behavior in adolescents and young adults. In a sample of 891 adolescents and young adults, social norms and attitudes were predictive of reporting intentions and subsequently, reporting behavior. For the purposes of this study, reporting behavior was defined as reporting the domestic violence to any individual not directly involved, which could include law enforcement personnel or other individuals who may provide assistance. Understanding how attitudes and social norms affect reporting behavior could be helpful for agencies serving individuals affected by domestic violence.     

Droplet-based optical trapping for cell separation in mock forensic samples

Optical tweezers have a wide range of uses for mechanical manipulation of objects in the microscopic range. This includes both living and static cells in a variety of biomedical and research applications. Single-focus optical tweezers, formed by focusing a laser beam through a high numerical aperture immersion objective, create a significant force, which enables controlled transport of a variety of different cell types and morphologies in three dimensions. Optical tweezers have been previously reported to capture and separate spermatozoa from a reconstituted simulated postcoital sample. We report herein the development of a simplified, more efficient cell transfer protocol that can separate and isolate both spermatozoa as well as leukocytes, with similar efficiencies as those previously reported. The new cell transfer method was used to separate sperm cells from a reconstituted mixture of spermatozoa and vaginal epithelial cells, with complete STR profiles developed from 50 cells with little evidence of contribution from the female contributor to the mixture. This modified protocol was then used to separate 21 samples of enriched leukocytes, with trapped cells ranging from 5 to 22 cells. Complete STR profiles were developed from as few as 10 leukocytes. Thus, with minimal sample preparation and a short trapping time, this method has the potential to provide an alternative to traditional differential extraction methods for separation of sperm:nonsperm mixtures while also providing versatility for separation of cells with differing morphologies.     

Young People,Children, Politics and Space: A Decade of Youthful Political Geography Scholarship 2003–13

This review essay covers a decade of scholarship developed by geographers who engage with children, young people and politics. It first outlines the boundaries within which the review was conducted. It then sets the scene of the starting points in 2003 of the when and where of the scholarship of children's and young people's political geographies. Section 3 provides focus on a wide range of contributions made in order to stake a claim within the wider discipline of Geography and explores the connections made with, and conceptions drawn from, feminist geography. Section 4 examines the ways in which the field has been expanded through conceptualisation and deconstruction of taken-for-granted approaches. Here, the intellectual value of reconsiderations or innovations of the concepts of scale, child and childhood, politics, agency, articulation, geopolitics and critical geopolitics are excavated and explicated. The paper ends with concluding thoughts and pointers towards the next decade of youthful political geographies and provides an extensive reference list covering a wide range of work on the subject.     

Qiagen's Investigator™ Quantiplex Kit as a Predictor of STR Amplification Success from Low‐Yield DNA Samples,

Qiagen's Investigator? Quantiplex kit, a total human DNA quantitation kit, has a 200‐base pair internal control, fast cycling time, and scorpion molecules containing a covalently linked primer, probe, fluorophore, and quencher. The Investigator? Quantiplex kit was evaluated to investigate a value under which complete short tandem repeat (STR) failure was consistently obtained. Buccal swabs were extracted using the Qiagen QIAamp^® DNA Blood Mini Kit, quantified with the Investigator? Quantiplex kit using a tested half‐volume reaction, amplified with the ABI AmpFlSTR^® Identifiler kit, separated on the 3100Avant Genetic Analyzer, and data analyzed with GeneMapper^® ID v.3.2. While undetected samples were unlikely to produce sufficient data for statistical calculations or CODIS upload (2.00 alleles and 0.82 complete loci on average), data may be useful for exclusionary purposes. Thus, the Investigator? Quantiplex kit may be useful for predicting STR success. These findings are comparable with previously reported data from the Quantifiler? Human kit.     

A systematic review of effective therapeutic interventions and management strategies for challenging behaviour in women in forensic mental health settings

Women in secure forensic mental health care require therapy and care that is responsive to their specific needs. Despite the policy recognition that women require a distinct service, evidence based practice is not available for this population. This review was undertaken in response to a clinical need within a medium secure unit in Glasgow that was experiencing high levels of challenging behaviour, in a female ward. The review aimed to identify effective strategies or interventions for the management of challenging behaviour in women in secure services and, therefore, improve practice and patient care. A synthesis of the findings from the 11 identified studies revealed variability in the approaches used to support women in forensic services, including: behavioural programmes; organisational change with a focus on staff training and support; medication; ECT and mechanical restraint. The challenging behaviours assessed included self-harm; physical and verbal aggression; suicide attempts and arson/fire setting. The majority of articles suggested some improvement in aspects of challenging behaviour, however this was limited by the lack of control groups and small sample sizes. Further investigation is required to find out whether interventions identified in this review can sustain a reduction in challenging behaviours in the long-term.     

Proactive Policing: a Summary of the Report of the National Academies of Sciences,Engineering, and Medicine

This paper provides a summary of our report for the National Academy of Sciences, Engineering, and Medicine on proactive policing. We find that there is sufficient scientific evidence to support the adoption of many proactive policing practices if the primary goal is to reduce crime, though the evidence base generally does not provide long-term or jurisdictional estimates. In turn, we conclude that crime prevention outcomes can often be obtained without producing negative community reactions. However, the most effective proactive policing strategies do not appear to have strong positive impacts on citizen perceptions of the police. At the same time, some community-based strategies have begun to show evidence of improving the relations between the police and public. We conclude that there are likely to be large racial disparities in the volume and nature of police–citizen encounters when police target high-risk people or high-risk places, as is common in many proactive policing programs. We could not conclude whether such disparities are due to statistical prediction, racial animus, implicit bias, or other causes.

     

An Optimized DNA Analysis Workflow for the Sampling,Extraction, and Concentration of DNA obtained from Archived Latent Fingerprints

DNA profiles have been obtained from fingerprints, but there is limited knowledge regarding DNA analysis from archived latent fingerprints—touch DNA “sandwiched” between adhesive and paper. Thus, this study sought to comparatively analyze a variety of collection and analytical methods in an effort to seek an optimized workflow for this specific sample type. Untreated and treated archived latent fingerprints were utilized to compare different biological sampling techniques, swab diluents, DNA extraction systems, DNA concentration practices, and post‐amplification purification methods. Archived latent fingerprints disassembled and sampled via direct cutting, followed by DNA extracted using the QIAamp® DNA Investigator Kit, and concentration with Centri‐Sep? columns increased the odds of obtaining an STR profile. Using the recommended DNA workflow, 9 of the 10 samples provided STR profiles, which included 7–100% of the expected STR alleles and two full profiles. Thus, with carefully selected procedures, archived latent fingerprints can be a viable DNA source for criminal investigations including cold/postconviction cases.     

Das neue Raumordnungsgesetz

Zum Jahreswechsel wurde das neue Raumordnungsgesetz verkündet, zur Jahresmitte wird das Gesetz in vollem Umfang in Kraft treten. Trotz mancher Verbesserungen im Detail ist es dem Gesetzgeber jedoch nicht gelungen, die rudiment?re Rolle des Bundes in der Raumentwicklungspolitik nennenswert aufzuwerten. Insgesamt best?tigt das in v?lligem Konsens von Bund und L?ndern ausgehandelte Gesetz die Befürchtung, dass die durch die F?deralismusreform 2006 geschaffenen L?nderabweichungsrechte die f?deralen Verantwortlichkeiten keineswegs entflechten, sondern vielmehr bereits im Gesetzgebungsverfahren einen kompromisshaften Konsens von L?ndern und Bund erzwingen.
