The analysis of substituted cathinones. Part 3. Synthesis and characterisation of 2,3-methylenedioxy substituted cathinones

The first synthesis of the 2,3-isomers of MDPV, butylone and methylone is reported. The isomers were characterised by (1)H and (13)C NMR spectroscopy and compared to the corresponding 3,4-isomers. A GC method is described which separates the 3,4- and the 2,3-isomers from each other. IR spectra of the 2,3-isomers are also compared with the corresponding 3,4-isomers. Two seized drug samples were analysed by GCMS and the samples were found to contain the 3,4-isomers.     

The Prevalence of Domestic Violence Against Women Among a Group Woman: Ankara,Turkey

This study determines the frequency of the spousal domestic violence among 1,178 married women who applied to some first level medical institutions located in Ankara, the capital of Turkey. 77.9% (n = 918) of the women who participated in the study have stated that they have been exposed to at least one of the types of spousal violence during their lifetime. The most reported type of domestic violence suffered by women throughout their lives is economic violence (60.4%). The prevalence of controlling behaviors, emotional violence, physical and sexual violence are 59.6%, 39.7%, 29.9% and 31.3% respectively.     

Big Five Personality Traits and Physical Aggression between Siblings in South Korea: an Actor-Partner Interdependence Analysis

The present study examined actor and partner effects of the Big Five personality traits, assessed by the NEO Five-Factor Inventory, on physical aggression within sibling dyadic interactions. Data were collected from 86 target adolescents receiving counseling services, their mothers, and closest-age siblings in South Korea. Mothers rated their children’s personalities. Target adolescents and siblings reported their own personality, as well as their sibling’s and their own perpetration of physical aggression against one another. Substantial self-other (i.e., mother and sibling) agreement was found for personality traits. Both actor and partner effects were found for the negative associations between extraversion, openness to experience, and conscientiousness and physical aggression among siblings. The current findings increase our understanding of personality traits implicated in physical aggression in general, and specifically aggression among siblings.     

Trace Evidence Potential in Postmortem Skin Microbiomes: From Death Scene to Morgue

Microbes can be used effectively as trace evidence, at least in research settings. However, it is unknown whether skin microbiomes change prior to autopsy and, if so, whether these changes interfere with linking objects to decedents. The current study included microbiomes from 16 scenes of death in the City and County of Honolulu and tested whether objects at the scenes can be linked to individual decedents. Postmortem skin microbiomes were stable during repeated sampling up to 60 h postmortem and were similar to microbiomes of an antemortem population. Objects could be traced to decedents approximately 75% of the time, with smoking pipes and medical devices being especially accurate (100% match), house and car keys being poor (0%), and other objects like phones intermediate (~80%). These results show that microbes from objects at death scenes can be matched to individual decedents, opening up a new method of establishing associations and identifications.     

Generating a Vertebrae‐based Method to Discriminate between Korean and U.S. White Male Casualties from the Korean War,

Low recovery rate of intact crania in conflict‐related contexts necessitates the use of postcranial elements for ancestry estimation. This study aimed to develop a new method to discriminate between Korean and U.S. White casualties from the Korean War using vertebrae. Maximum body heights of C2 through L5 were measured from 75 Korean and 51 U.S. males to generate discriminant functions. U.S. vertebral heights were statistically greater than Koreans in 18 out of 23 vertebrae (C2, C4‐6, T3‐6, and T8‐L5). The functions with lumbar vertebrae tended to yield higher correct classification ratios (CCR) than those with cervical or thoracic vertebrae. Inclusion of the femur and tibia lengths in the vertebrae‐involved functions enhanced the CCR's. Discriminant functions using the femur and tibia length were also presented. The results of this study are expected to complement the current practices of the Defense POW/MIA Accounting Agency and the Ministry of National Defense Agency for KIA Recovery and Identification, which are primarily based on cranial and dental morphology.     

Psychophysiological Responses of People with Psychopathic Tendencies to the Concealed Information Test

This study was designed to investigate differences in psychophysiological responses among individuals with psychopathic tendencies. A total 40 students were participated and were divided into two groups based on Levenson Self‐Report Psychopathy Scale (LSRP) scores: a high psychopathic tendency group selected from the top 5% of LSRP scores, and a low psychopathic tendency group selected from the bottom 5% of LSRP scores. All participants were instructed to perform a mock crime and complete the concealed information test (CIT). Results indicate that significant differences between crime‐relevant questions and irrelevant questions were observed for respiration line length and skin conductance response in both groups, but heart rate did not significantly differ between groups. There were no differences in psychophysiological responses between the groups. In conclusion, CIT was found to be an effective method for detecting crime‐relevant information in individuals with psychopathic tendencies.     

Sequences of the Cytochrome C Oxidase Subunit I (COI) Gene are Suitable for Species Identification of Korean Calliphorinae Flies of Forensic Importance (Diptera: Calliphoridae)

Abstract:  Calliphorinae fly species are important indicators of the postmortem interval especially during early spring and late fall in Korea. Although nucleotide sequences of various Calliphorinae fly species are available, there has been no research on the cytochrome c oxidase subunit I (COI) nucleotide sequences of Korean Calliphorinae flies. Here, we report the full-length sequences of the COI gene of four Calliphorinae fly species collected in Korea (five individuals of Calliphora vicina , five Calliphora lata , four Triceratopyga calliphoroides and three Aldrichina grahami ). Each COI gene was amplified by polymerase chain reaction and directly sequenced and the resulting nucleotide sequences were aligned and analyzed by MEGA4 software. The results indicate that COI nucleotide sequences can be used to distinguish between these four species. Our phylogenetic result coincides with recent taxonomic views on the subfamily Calliphorinae in that the genera Aldrichina and Triceratopyga are nested within the genus Calliphora .

Long-term impact of family group conferences on re-offending: the Indianapolis restorative justice experiment

Objectives

The purpose of the current study is to test the long-term effect of Family Group Conferences (FGCs) on recidivism prevalence and time to first re-offense for first-time youthful offenders.

Methods

The current study builds on an experiment with a reasonably large sample (n?=?782) conducted in Marion County (Indianapolis), Indiana, USA. The current study extends this work by following the cases for an additional 10?years. To examine the empirical relationships among the variables, this study employs a two-step approach. The initial analysis, employing logistic regression, measures prevalence of re-offending based on whether the youth ever was re-arrested during the follow-up period. The second step employs Cox Proportional-Hazards Regression to examine time until first re-offense.

Results

The findings revealed that when extended to a 12-year follow-up period, there were no significant differences between the FGC and control groups in re-offending prevalence or time to re-offense.

Conclusions

An earlier study suggests that treatment group youths experienced reduced risk in the short-term and there is no evidence in the present study to suggest that youths participating in FGCs were placed at greater risk for re-offending. Given these findings and the body of research suggesting improved outcomes for victims, continued experimentation with FGCs and related restorative processes seems warranted. Future studies would benefit from blocking procedures in the experimental design in order to examine whether treatment effects are moderated by gender, race, and initial type of offense. The lack of such blocking procedures represents a limitation of the current study.
