Sex determination from the talus of Koreans by discriminant function analysis

The aims of this study were to investigate the sex discriminating potential of the talus in Koreans and compare this with other analyses in different populations. Statistical analyses were performed using data from nine measurements acquired from 140 tali (70 men, 70 women). The talus of Koreans is dimorphic between sexes in all measurements (p < 0.01). Discriminant function equations were generated by univariate, multivariate, and stepwise methods with a range of accuracy from 67.1 to 87.1%. Stepwise equations of other populations did not discriminate the sex of the Korean sample as accurately as each equation's own accuracies. The variables with high accuracy in this study are useful for sex determination of Koreans on the basis of confirmation of population specificity.     

Determination and validation of tetrodotoxin in human whole blood using hydrophilic interaction liquid chromatography-tandem mass spectroscopy and its application

A sensitive analytical method was developed for the quantitative determination of tetrodotoxin (TTX), a powerful sodium channel blocker, in human postmortem whole blood. The sample mixture was cleaned up using cation exchange SPE catridge after protein precipitation by methanol and then separated on a PC-HILIC (phosphorylcholine hydrophilic interaction liquid chromatography) column (150 mm × 2.0mm i.d., 5 μm) using a isocratic elution of 1% acetic acid and acetonitrile. The identification of TTX was performed on tandem mass spectrometry with electrospray ionization interface in positive ion mode. The retention time of voglibose (internal standard) and TTX was 5.1 and 6.0 min, respectively. TTX and internal standard (voglibose) were monitored and quantitated using the ion transitions: the respective precursor to product ion combinations, m/z 320/302 for TTX and m/z 268/92 for voglibose in the multiple reaction monitoring (MRM) mode. The recovery of TTX and voglibose was 61.4% and 62.8%, respectively and the good accuracy (97.7-103.9%), linearity (2-1200 ng/mL) and reproducibility were shown in this method. The limit of detection and limit of quantification were 0.32 ng/mL and 1.08 ng/mL, respectively. This method was applied in the case of three fishermen who were poisoned (including one death) by unknown fish on their boat in October 2010. In this case, the levels of TTX were 27.2, 30.0 and 29.7 ng/mL in heart blood, peripheral blood and serum of a victim, were 3.1 and 12.1 ng/mL in peripheral blood and 3.9 and 12.8 ng/mL in serum of two survivors, respectively.     

Genetic and chemical components analysis of Papaver setigerum naturalized in Korea

Of the 110 species of genus Papaver, only Papaver somniferum and P. setigerum are controlled poppies in Korea. All poppy samples share similar morphology therefore it is important to check if they contain controlled substances such as morphine and codeine for forensic purpose. Since the alkaloid content of Papaver plants varies according to their growing stage, chemical components analysis alone is not enough to identify exact species. In 2010, hundreds of poppy plants suspected to be P. somniferum were found in Jeju Island, South Korea. They had a slightly different but overall similar appearance to P. somniferum. Using GC-MS analysis, codeine, rhoeadine, papaverine, protopine, noscapine, setigeridine and trace amounts of morphine were detected in these samples. Although their chemical components were different from what has been described in literatures for P. setigerum, they could be assumed to be P. setigerum based on their morphological features and GC-MS results. Also, chromosome numbers using their seeds showed 2n=44 and the numbers were in accordance with those of P. setigerum. Nucleotide substitution or insertion/deletion of ITS (internal transcribed spacer), 18S rRNA (ribosomal RNA), rbcL (large subunit of ribulose 1,5-bisphosphate carboxylase), trnL-trnF IGS (intergenic spacer), trnL intron and psbA-trnH were assessed as universal genetic markers for P. setigerum. Also, genetic analysis using six target genes involved in the biosynthesis of benzylisoquinoline alkaloids, including TYDC (tyrosine/dopa decarboxylase), SAT (salutaridinol-7-O-acetyltransferase), BBE (berberine bridge enzyme), COR (codeinone reductase), CYP80B1 ((S)-N-methylcoclaurine 3'-hydroxylase) and NCS (norcoclaurine synthase) were tested as Papaver-specific genetic markers by the existence of their PCR products. From the results, the sequences of the 6 universal genetic markers and 6 Papaver-specific genetic markers for P. setigerum were identified and then Genbank accession numbers of them were registered in NCBI. Also, the trnL intron and psbA-trnH nucleic acid sequences of the 7 Papaver species were identified and registered.     

Understanding economic abuse in the lives of survivors

Intimate partner violence (IPV) often includes economic abuse as one tactic commonly used by an abuser; unfortunately, there is a lack of empirical understanding of economic abuse. Additionally, research is limited on the predictors of economic self-sufficiency in the lives of women experiencing IPV. This paper furthers our knowledge about economic abuse and its relationship with economic self-sufficiency by presenting the results from an exploratory study with IPV survivors participating in a financial literacy program. Of the 120 individuals who participated in the first wave, 94% experienced some form of economic abuse, which also correlated highly with other forms of IPV. Seventy-nine percent experienced some form of economic control, 79% experienced economic exploitative behaviors, and 78% experienced employment sabotage. MANOVA results also indicated that economic control differed significantly based on education with those with a high school education experiencing higher rates than those with less than high school education or those with some college. Finally, results from the OLS regressions indicated that experiencing any form of economic abuse as well as economic control significantly predicted a decrease in economic self sufficiency. Implications suggest that advocates should assess for economic abuse when working with survivors and should be prepared to offer financial tools to increase survivors' economic self-sufficiency. Policymakers should understand the ramifications of economic abuse and create policies that support survivors and prohibit economic abuse. Finally, more research is needed to fully understand economic abuse and its impact on survivors and their economic self-sufficiency.     

Screening for intimate partner violence in orthopedic patients: a comparison of three screening tools

Accurately identifying victims of intimate partner violence (IPV) can be a challenge for clinicians and clinical researchers. Multiple instruments have been developed and validated to identify IPV in patients presenting to health care practitioners, including the Woman Abuse Screening Tool (WAST) and the Partner Violence Screen (PVS). The purpose of the current study is to determine if female patients attending an outpatient orthopaedic fracture clinic who screen positive for IPV using three direct questions (direct questioning) also screen positive on the WAST and PVS. We conducted a prevalence study at two Level I trauma centres to determine the prevalence of IPV in female patients presenting to orthopaedic fracture clinics for treatment of injuries. We used three methods to determine the prevalence of IPV; 1) direct questioning, 2) WAST, and 3) PVS. We compared the prevalence rates across the three screening tools. Ninety-four women screened positive for IPV using any method. The prevalence of IPV was 30.5% when a direct questioning approach was utilized, 12.4% using the WAST, and 9.2% using the PVS. The WAST identified 37.2% (35/94) of the IPV victims detected and the PVS identified 27.7% (53/94) of the IPV victims detected, whereas direct questioning identified 89.4% of the IPV victims. Identification of IPV may be under-estimated by the WAST and PVS screening tools. Our findings suggest direct questioning may increase the frequency of disclosure of IPV among women attending outpatient orthopaedic clinics.     

Is harmonization of legal rules an appropriate target? Lessons from the global financial crisis

This article deals critically with the call for a comprehensive harmonization of legal rules, against the background of the lessons from the recent financial crisis. Before coming to the topic of harmonization of legal rules, it first briefly deals with the question of why rules are necessary at all, and what the functions of rules are. Then it deals with the lessons from the recent financial crisis for the topic mentioned. The article conducts a kind of cost-benefit analysis of legal harmonization by looking at arguments in favor of and against uniform rules. It shows that not only the arguments in favor have increased after the recent financial crisis, but also the arguments against. It also shows that integration of global markets has not only increased the need for new uniform rules but also decreased the chances of their implementation; and that therefore today it is often better to improve the implementation of current rules instead of laying down new uniform rules.

Effectiveness of modified therapeutic community treatment within a medium-secure service for personality-disordered offenders

There is debate as to whether secure hospital treatment for offenders with personality disorder can be effective relative to criminal justice interventions. This study examines the evidence for long-term treatment of such offenders in hospital within in a modified therapeutic community model including accredited offending behaviour programmes. A panel sample of 47 patients were followed up on measures of violence risk (HCR-20, VRS) and symptom severity (SCL90-R). Intention-to-treat analysis with reliability thresholds showed significant positive change between assessment and discharge in both violence risk (VRS) and symptoms (SCL90-R) indicating a positive treatment effect. Threshold effects for treatment effectiveness seemed to occur at 1?year of treatment for risk and 3?years for symptom reduction.     

Socio‐legal Studies in Aotearoa/New Zealand

This article reviews the development and impact of the socio‐legal field in New Zealand. It begins by assessing the socio‐legal presence within teaching and research conducted across New Zealand's law faculties before analysing factors likely to inhibit future growth of the sub‐discipline in this remote jurisdiction. Having examined how New Zealand's legal scholars map and influence national legal behaviour, without always recognizing contradictions between these objectives or categorizing their research as ‘socio‐legal’, the article goes on to examine how the next generation of socio‐legal researchers might exert stronger influence over the law curriculum and new areas of legal policy. In conclusion, it argues for a distinctive New Zealand approach toward socio‐legal studies and notes that future prospects appear encouraging, and in certain respects more promising than those in the United Kingdom, particularly when considering research impact.     

Adverse Neighborhood Conditions and Sanction Risk Perceptions: Using SEM to Examine Direct and Indirect Effects

Objectives

The present study examines how individuals’ sanction risk perceptions are shaped by neighborhood context.

Methods

Using structural equation modeling on data from waves 6 and 7 of the National Youth Survey, we assess the direct and indirect relationships between adverse neighborhood conditions and two dimensions of sanction risk perceptions: the certainty of punishment and perceived shame. In addition, the role of shame as a mediator between neighborhood context and certainty of punishment is also investigated.

Results

The results indicate that adverse neighborhood conditions indirectly affect both forms of sanction risk perceptions, and additional results show that perceived shame fully mediates the effect of neighborhood conditions on perceptions of the certainty of punishment.

Conclusions

The perceptual deterrence/rational choice perspective will need to be revised to accommodate more explicitly the role of neighborhood context in shaping sanction risk perceptions.
