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.     

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.     

An Assessment of the Utility of Universal and Specific Genetic Markers for Opium Poppy Identification

Abstract: The proper identification of illicit plants such as Papaver somniferum L (opium poppy) is important for law enforcement agencies. The identification of opium poppy was presently tested using 10 genetic markers that are universal for all plants or specific to a few poppy plants. The genetic distances of universal markers such as nuclear internal transcribed spacer (ITS), 18S rRNA, plastid rbcL, and trnL‐trnF intergenic spacer (IGS) of 14 species included in the Papaveraceae and Fumariaceae family were acquired by sequence comparisons. Both the ITS region and trnL‐trnF IGS showed high levels of interspecific divergence. Six Papaver genera‐specific markers were developed from coding regions involved in morphine biosynthesis. Three markers (TYDC, NCS, and BBE) produced amplicons only in opium poppy, providing a presence/absence test for opium poppy, while three additional markers (CYP80B1, SAT, and COR) were genus specific. These 10 markers might be useful for the forensic DNA analysis of opium poppy.     

Production networks in China and India: a comparative analysis

In this paper, we examine and compare the two important production hubs in Asia: China and Greater China and India and South Asia. We show that in China, Hong Kong and Taiwan, manufacturing trade has continued to be highly relevant, with trade in parts and components growing in importance. In contrast, in India, Pakistan and Sri Lanka, trade in parts and components remain limited. We then calculate various revealed comparative advantage (RCA) indices, which China having more components with RCA values exceeding one. Some of the most important components exported by China include electronic parts and telecommunication parts. One explanation is to why India is relatively weak in parts and components trade is that India is strong in service trade. Other reasons may be related to better port infrastructure, higher research and development intensity and higher educational enrollments in China.     

A Novel Forged Image Detection Method Using the Characteristics of Interpolation

Development of digital image‐editing programs has enabled us to be widely exposed to forged digital images surrounding us. Such forged images have been dispersed through the Internet, newspaper articles, and magazines, and in particular, the information contained in these unverified images happened to be regarded as true. As a result, the forged images provided wrong information for individuals and society, thus sometimes creating social issues. In order to solve such problems, this study was aimed to suggest the methods of identifying the veracity of forged images. In this way, it suggested re‐interpolation algorithm. Namely, the study re‐interpolated in identical arbitrary values both the interpolated and un‐interpolated regions based on the interpolation used a lot in forged, confirmed discrete fourier transform (DFT) characteristics of these two regions, and embodied a detection map for the final forged images, using the subtraction value between two regions in DFT characteristics.     

Pathways into Terrorism: Understanding Entry into and Support for Terrorism in Asia

ABSTRACT

How do individuals join Islamist extremist groups? Why do individuals support such groups? What factors contribute to a decision to join? What are the pathways into Islamist extremist groups? Drawing on examples from Pakistan, Bangladesh, Indonesia and the Philippines, the articles in this special issue address these critically important questions drawing on original fieldwork, new datasets and large scale national survey research. These articles explore the experiences and perceptions of men and women, South and Southeast Asians, living in majority Muslim and non-Muslim nations. Collectively, they illustrate the importance of social bonds&kinship ties, friendship, teacher-student ties and online relationships in creating a powerful sense of community that fosters a sense of belonging and eventual commitment. The goal of this special issue is to highlight the contributions that Asian cases can make to the often Middle Eastern and European-centric discourses on radicalization, joining and support for militancy.     

Why They Join: Pathways into Indonesian Jihadist Organizations

ABSTRACT

Why do Indonesian Muslims join Islamist extremist groups? This article explores four pathways to entry into Indonesian militant groups: study sessions, local conflict, kinship, and schools. It argues that within all four of these pathways, social bonds and relationships are the common thread in encouraging entry as well as in fostering commitment. Specifically, these relationships contribute to the formation and eventual consolidation of one’s identity as a member of the jihadi group through regular participation in activities, attending meetings, narrowing the circle of friends to those within the group, and participating in increasingly risky and possibly violent activities together. Drawing on original fieldwork including 49 interviews with current and former members of Jemaah Islamiyah, Mujahidin KOMPAK, Darul Islam, Mujahidin Tanah Runtuh, Indonesia’s pro-ISIS network, and other jihadist groups as well as 57 depositions and court documents, this article explores the development and evolution of these pathways and how relational ties play a role in each.     

Protest by candlelight: A comparative analysis of candlelight vigils in South Korea

ABSTRACT

Protest activist leaders must make a series of decisions about the strategies they use; one such decision is the choice of tactic or performance, often informed by their cultural historic contentious repertoire. In South Korea's contentious repertoire, the use of candlelight vigils has become an increasingly prevalent form of protest tactic. Candlelight vigils have become an increasingly prominent tactic in South Korea’s repertoire over the last two decades, as evidenced by major candlelight vigils in 2002, 2008, and 2016-2017. In this study, we explore the ways in which candlelight vigils as a protest tactic have evolved over time in South Korea. We notably find that vigils emerged as a left-wing protest tactic in 2002, but right-wing protesters began adopting the tactic during the counter-protests opposing President Park Geun-Hye’s impeachment in 2016–2017 (Taegeukgi Giphoei). Additionally, we find that candlelight vigils drew participants from an increasingly wide swath of society over time and average citizens assumed greater organizational roles. This research not only contributes to the literature on South Korean social movements and civil society, but to understanding candlelight vigils as a distinct form of protest and how contentious repertoires evolve over time more broadly.     

Single Nucleotide Polymorphism Assay for Genetic Identification of Lophophora williamsii*

Lophophora is a member of the Cactaceae family, which contains two species: Lophophora williamsii and L. diffusa. Lophophora williamsii is an illegal plant containing mescaline, a hallucinogenic alkaloid. In this study, a novel method based on a single nucleotide polymorphism (SNP) assay was developed for identifying L. williamsii; this assay reliably detects SNPs within chloroplast DNA (rbcL, matK, and trnL-trnF IGS) and was validated for identifying Lophophora and L. williamsii simultaneously. The chloroplast DNA sequences from four L. williamsii and three L. diffusa plants were obtained and compared using DNA sequence data from approximately 300 other Cactaceae species available in GenBank. From this sequence data, a total of seven SNPs were determined to be suitable for identifying L. williamsii. A multiplex assay was constructed using the ABI PRISM^® SNaPshot™ Multiplex Kit (Applied Biosystems, Forster City, CA) to analyze species-specific SNPs. Using this multiplex assay, we clearly distinguished the Lophophora among 19 species in the Cactaceae family. Additionally, L. williamsii was distinguished from L. diffusa. These results suggest that the newly developed assay may help resolve crimes related to illegal distribution and use. This multiplex assay will be useful for the genetic identification of L. williamsii and can complement conventional methods of detecting mescaline.
