Possibilities of the positive following violence and trauma: informing the coming decade of research

The effects of trauma and violence may be better understood by taking a broader perspective that includes resilience and recovery as well as damage and symptomatology. Based on this broader view, this article describes three interrelated, cutting-edge trends in mental health research: (a) the positive psychology movement, (b) the recognition of the role of spirituality and religion in health and well-being, and (c) stress-related growth. The integration of these trends into mainstream studies of trauma and violence will provide a counterbalance to the predominant orientation of victimization and pathology currently evidenced in the literature. All three have important implications for survivors of violence and trauma.     

An analysis of Korean homicide crime-scene actions

Recent studies have focused on how different styles of homicides will be reflected in the different types of behaviors committed by offenders at a crime scene. It is suggested that these different types of behaviors best be understood using two frameworks, expressive/instrumental aggression and planned/unplanned violence, to analyze the way the offender acts at the crime scene. Multidimensional analysis is carried out on the crime-scene actions of 70 Korean homicides. The proposed frameworks are found to be a useful way of classifying homicide offenses, assigning 80% of homicides to a dominant theme. Results also indicate that behavioral differences can be related to the differences in the offender-victim relationship. Finally, implications and suggestions for future research are discussed.

2011年的菲律宾,经济总体表现不如预期;在国内政治方面,政府三权之间冲突不断引发宪政危机。此外,政府与国内分裂势力之间的谈判进展也不顺利,和解之路依然任重道远。外交方面,对外关系处于急剧变动时期,菲中关系喜忧参半,菲美、菲日关系急剧升温。     

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.     

An explanation for camera perspective bias in voluntariness judgment for video-recorded confession: Suggestion of cognitive frame

Three experiments were conducted to test the hypothesis that difference in voluntariness judgment for a custodial confession filmed in different camera focuses ("camera perspective bias") could occur because a particular camera focus conveys a suggestion of a particular cognitive frame. In Experiment 1, 146 juror eligible adults in Korea showed a camera perspective bias in voluntariness judgment with a simulated confession filmed with two cameras of different focuses, one on the suspect and the other on the detective. In Experiment 2, the same bias in voluntariness judgment emerged without cameras when the participants were cognitively framed, prior to listening to the audio track of the videos used in Experiment 1, by instructions to make either a voluntariness judgment for a confession or a coerciveness judgment for an interrogation. In Experiment 3, the camera perspective bias in voluntariness judgment disappeared when the participants viewing the video focused on the suspect were initially framed to make coerciveness judgment for the interrogation and the participants viewing the video focused on the detective were initially framed to make voluntariness judgment for the confession. The results in combination indicated that a particular camera focus may convey a suggestion of a particular cognitive frame in which a video-recorded confession/interrogation is initially represented. Some forensic and policy implications were discussed.     

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.     

Application of Micro‐Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy to Ink Examination in Signatures Written with Ballpoint Pen on Questioned Documents

Questioned documents examined in a forensic laboratory sometimes contain signatures written with ballpoint pen inks; these signatures were examined to assess the feasibility of micro‐attenuated total reflectance (ATR) Fourier transform infrared (FTIR) spectroscopy as a forensic tool. Micro‐ATR FTIR spectra for signatures written with 63 ballpoint pens available commercially in Korea were obtained and used to construct an FTIR spectral database. A library‐searching program was utilized to identify the manufacturer, blend, and model of each black ballpoint pen ink based upon their FTIR peak intensities, positions, and patterns in the spectral database. This FTIR technique was also successfully used in determining the sequence of homogeneous line intersections from the crossing lines of two ballpoint pen signatures. We have demonstrated with a set of sample documents that micro‐ATR FTIR is a viable nondestructive analytical method that can be used to identify the origin of the ballpoint pen ink used to mark signatures.
