Positive Effects in Detecting Lies from Training to Recognize Behavioral Anomalies

We examined whether training in both the verbal and nonverbal indicators of truth telling and lying would have positive effects on Law Enforcement Officers’ (LEOs) ability to evaluate truths from lies. College course-level training on empirically validated verbal and nonverbal indicators of truth telling and lying was provided to mid- to advanced-career level LEOs, whose accuracy in detecting lies from truths was assessed pre- and post-training using truthful and deceptive videos of mock crimes and opinions. A marginally significant truth bias existed at pre-test; training, however, resulted in a significant improvement in accuracy rates for both truth and lie videos, and the truth bias that existed at pre-test was eliminated. Additional analyses indicated that accuracy rates improved for videos of mock crimes but not for opinions. These findings add to a small but growing literature that indicates that training on validated verbal and nonverbal indicators of truth telling and lying has positive benefits.     

Changing South Korean Water Policy after Political and Economic Liberalisation

This study explores the way in which South Korean water policy has been dynamically (re-)constructed by continuing political contestations among diverse social forces acting in and through the state in the face of political and economic liberalisation. The path-dependency of the state-driven water resource policy under the former authoritarian regime did not disappear even after the democratisation. It was difficult to transform the old authoritarian and hierarchical water governance to the newly democratic and environmentally friendly one because the Ministry of Construction, as a main actor in driving water policy under the authoritarian regimes, did not give up its interest in a dam-based policy orientation, although it did partially accept institutional tools for democratic policy making, such as public hearings and the participation of civil society in the process of establishing the water policy plan. It also showed democratic and environment-friendly gestures using the rhetoric of environmentalism and localisation. Overall, this article emphasises the importance of the path-dependency of the past authoritarian regimes under democratised society to better understand the current democratic regime’s policy orientation.     

Potential Forensic Application of Receptor for Advanced Glycation End Products (RAGE) as a Novel Biomarker for Estimating Postmortem Interval

Studies which estimate the postmortem interval (PMI) based on diatoms or bacterial communities have been well‐conducted. However, predicting the PMI based on microorganisms has limited accuracy. The objective of this study was to discover specific biomarkers for estimating the PMI for drowning. The in vivo experimental model consisted of rats classified into nine groups (seven drowned groups from Day 1 to Day 7 and two control groups). Their lung tissues were analyzed for the receptor for advanced glycation end products (RAGE) mRNA expression determined by qRT‐PCR. RAGE protein levels were determined by Western blotting and immunohistochemical (IHC) staining. RAGE mRNA and protein levels gradually degraded over time. Immunostaining analysis revealed that RAGE in the Day 1 sample was significantly higher than that in the Day 6 or Day 7 samples. These results indicate that RAGE in drowned lungs could be a potential biomarker for the determination of the PMI after drowning.     

BrowStExPlus: A Tool to Aggregate IndexedDB Artifacts for Forensic Analysis

As the Internet and World Wide Web have rapidly evolved and revolutionized the applications in everyday life, it is a demanding challenge for investigators to keep up with the emerging technologies for forensic analyses. Investigating web browser usages for criminal activities, also known as web browser forensics, is a significant part of digital forensics as crucial browsing information of the suspect can be discovered. Particularly, in this study, an emerging web storage technology, called IndexedDB, is examined. Characteristics of IndexedDB technology in five major web browsers under three major operating systems are scrutinized. Also, top 15 US websites ranked by Alexa are investigated for their data storage in IndexedDB. User screen names, ids, and records of conversations, permissions, and image locations are some of the data found in IndexedDB. Furthermore, BrowStEx, a proof‐of‐concept tool previously developed, is extended and cultivated into BrowStExPlus, with which aggregating IndexedDB artifacts is demonstrated.     

Differences between Homicides Committed by Lone and Multiple Offenders in Korea

The aim of this study was to differentiate between homicides committed by multiple offenders and homicides committed by lone offenders. Using data on homicide incidents that occurred in South Korea between 1985 and 2008, we compared 134 homicides committed by multiple offenders, with 369 homicides committed by lone offenders. A greater proportion of homicides committed by multiple offenders involved injuries to the victim's head compared to homicides by lone offenders. Homicides committed by multiple offenders were more likely to involve blunt instruments and ligatures, whereas homicides by lone offenders were more likely to involve sharp instruments. In addition, a majority of the homicides committed by multiple offenders were planned. The results of this study have practical implications for homicide investigations, as well as theoretical implications for homicide research on the difference in offense behaviors based on the number of offenders.     

Identification of Mobile Phone and Analysis of Original Version of Videos through a Delay Time Analysis of Sound Signals from Mobile Phone Videos

This study designs a method of identifying the camera model used to take videos that are distributed through mobile phones and determines the original version of the mobile phone video for use as legal evidence. For this analysis, an experiment was conducted to find the unique characteristics of each mobile phone. The videos recorded by mobile phones were analyzed to establish the delay time of sound signals, and the differences between the delay times of sound signals for different mobile phones were traced by classifying their characteristics. Furthermore, the sound input signals for mobile phone videos used as legal evidence were analyzed to ascertain whether they have the unique characteristics of the original version. The objective of this study was to find a method for validating the use of mobile phone videos as legal evidence using mobile phones through differences in the delay times of sound input signals.     

Aspects of Help Seeking among Collegiate Victims of Dating Violence

This study applied Andersen’s model of health service use to help-seeking among collegiate dating violence (DV) victims, and examined factors for help-seeking. A total of 338 students from a Midwest public university were included in the sample. The study results showed many college students experience psychological, physical, sexual and technological violence; substance use is associated with DV; the type of violence experienced is associated with the type of help sources that victims will use; and victims seek help from informal sources more than formal sources. Implications for social work research, practice and policy are discussed.     

Species identification of Papaver by metabolite profiling

This paper analyses and discusses arguments that emerge from a recent discussion about the proper assessment of the evidential value of correspondences observed between the characteristics of a crime stain and those of a sample from a suspect when (i) this latter individual is found as a result of a database search and (ii) remaining database members are excluded as potential sources (because of different analytical characteristics). Using a graphical probability approach (i.e., Bayesian networks), the paper here intends to clarify that there is no need to (i) introduce a correction factor equal to the size of the searched database (i.e., to reduce a likelihood ratio), nor to (ii) adopt a propositional level not directly related to the suspect matching the crime stain (i.e., a proposition of the kind 'some person in (outside) the database is the source of the crime stain' rather than 'the suspect (some other person) is the source of the crime stain'). The present research thus confirms existing literature on the topic that has repeatedly demonstrated that the latter two requirements (i) and (ii) should not be a cause of concern.     

Describing intimate partner stalking over time: an effort to inform victim-centered service provision

Stalking has increasingly been the subject of legislation and research in the past 20 years. Within intimate partner violence, the context where it is most likely to occur, stalking predicts both greater danger and greater distress for the victim. However, research shows that practitioners are often unsure how to address stalking, and that the remedies available may not be effective. This longitudinal exploration of stalking focused on the experience of victims of intimate partner stalking and was conducted by Safe Horizon, an organization providing assistance to victims of violence and abuse in New York City. The sample of 82 women was interviewed monthly over 7 months, and the data were analyzed using growth curve models. We found that stalking decreased over time at a marginally significant level, and that change in stalking varied among participants. Perceived safety followed a similar pattern, increasing but not significantly, while stalking-related distress decreased significantly. The slopes of these variables were correlated, such that as stalking frequency decreased, perceived safety increased and distress decreased. Help-seeking was greater from court sources than victim services over the course of the study, but neither help source was related to a significant decrease in the stalking trajectory. According to victim report, orders of protection (OP) were helpful at some points and not at others. Implications of these results for offering victim-centered services are discussed.
