The impact of fentanyl on DUIDs and traffic fatalities: Blood and oral fluid data

Fentanyl has emerged as the most prolific drug in the ongoing opioid epidemic and has greatly impacted traffic safety in recent years. This study aimed to evaluate fentanyl prevalence and concentrations in blood and oral fluid in driving under the influence of drugs (DUID) cases in three different regions (i.e., Alabama, Orange County, CA, and Houston, TX) from 2017 to 2022. Furthermore, traffic fatalities were evaluated for Alabama and Orange County, CA. Fentanyl positivity in DUID and traffic fatalities increased for most years in this study. In Alabama, the prevalence of fentanyl DUID cases increased 4-fold in 2022 compared to 2017. Orange County's increase from 2017 to 2022 was 14-fold. In Houston, the increase was approximately 2-fold from 2019 to 2022. The greatest increase for all laboratories coincided with the start of the COVID-19 pandemic. In 2022, the median fentanyl DUID blood concentrations were 4.7, 11, and 4.7 ng/mL in Alabama, Orange County, and Houston, respectively. Most fentanyl cases were polydrug cases (≥90%). Methamphetamine, THC, and alprazolam were the most frequently detected drugs in combination with fentanyl. Alabama has collected oral fluid and blood in DUID cases since 2018. The detection of fentanyl in oral fluid was comparable to blood. However, 59% and 8.7% of fentanyl-positive cases had concentrations of >20 ng/mL in oral fluid and blood, respectively. Therefore, oral fluid as an alternative or supplemental specimen to blood is an attractive approach for fentanyl in DUID cases. This study contributes to understanding recent fentanyl trends and their impact on traffic safety.     

Forensic integrity verification of video recordings based on MTS files

Digital video is used in criminal trials as evidence with legal responsibility because video content vividly depicts events occurring at a crime scene. However, using sophisticated video editing software, assailants can easily manipulate visible clues for their own benefit. Therefore, the integrity of digital video files acquired or submitted as evidence must be ensured. Forensic analysis of digital video is key to ensuring the integrity of links with individual cameras. In this study, we analyzed whether it is possible to ensure the integrity of MTS video files. Herein, we propose a method to verify the integrity of MTS files encoded by advanced video coding high definition (AVCHD), which is frequently used for video recording. To verify MTS file integrity, we propose five features. Codec information, picture timing, and camera manufacture/model are modified AVI and MP4-like format video verification features. Group of pictures and Universally Unique Identifier patterns were specifically developed for MTS streams. We analyzed the features of 44 standard files recorded using all recording options of seven cameras. We checked whether integrity can be validated on unmanipulated videos recorded in various environments. In addition, we considered whether manipulated MTS files edited in video editing software could be validated. Experimental results show that all unmanipulated and manipulated MTS files with known recording devices were discriminated only when all five features were checked. These results show that the proposed method verifies the integrity of MTS files, strengthening the validity of MTS file-based evidence in trials.     

A reference database of Windows artifacts for file-wiping tool execution analysis

Anti-forensic technology can play an effective role in protecting information, but it can make forensic investigations difficult. Specifically, file-wiping permanently erases evidence, making it challenging for investigators to determine whether a file ever existed and prolonging the investigation process. To address this issue, forensic researchers have studied anti-forensic techniques that detect file-wiping activities. Many previous studies have focused on the effects of file-wiping tools on $MFT, $LogFile, and $DATA, rather than on Windows artifacts. Additionally, previous studies that have examined Windows artifacts have considered different artifacts, making it difficult to study them in a comprehensive manner. To address this, we focused on analyzing traces in 13 Windows artifacts of 10 file-wiping tools' operations in the Windows operating system comprehensively. For our experiments, we installed each file-wiping tool on separate virtual machines and checked the traces that the tools left behind in each artifact. We then organized the results in a database format. Our analysis revealed that most of the tools left traces on other artifacts, except for JumpList, Open&SavePidlMRU, and lnk. There were also some cases where traces remained on the other three artifacts. Based on our research, forensic investigators can quickly identify whether a file-wiping tool has been used, and it can assist in decision-making for evidence collection and forensic triage.

Globalization and Divergent Paths of Industrial Development: Mobile Phone Manufacturing in China,Japan, South Korea and Taiwan

Globalisation has challenged the way industrial development takes place. Fragmented and decentralised global production and the rapid growth of consumer markets in emerging economies demand a more sophisticated framework to analyse development paths than does the dichotomy of export orientation and import substitution. This article proposes a typology based on (a) specialisation in the global value chain and (b) market orientation to distinguish different development trajectories and then applies the typology to mobile phone manufacturing in four East Asian countries. This study finds that globalisation does not lead to the convergence of development paths, but promotes cross-national divergence depending on countries’ positions in the value chain and market niches. Both Korea and Taiwan emerge as key players in global markets, yet in different parts of the global value chain. Their common orientation toward global markets strikingly contrasts the inability of Japanese firms to translate their domestic success overseas. Finally, Chinese firms concurrently engage in different development paths, making the country’s multi-path approach unique. The implications of these findings are discussed in terms of industrial development in East Asia in an era of globalisation.     

Oil,Natural Gas,and Intrastate Conflict: Does Ownership Matter?

The impact of natural resources on intrastate violence has been increasingly analyzed in the peace and conflict literature. Surprisingly, little quantitative evidence has been gathered on the effects of the resource-ownership structure on internal violence. This article uses a novel data set on oil and natural gas property rights, covering 40 countries during the period 1989–2010. The results of regression analyses employing logit models reveal that the curvilinear effect between hydrocarbon production and civil conflict onset—often found in previous studies—only applies to countries in which oil and gas is extracted by state-owned companies. The findings suggest that only state-controlled hydrocarbon production might entail peace-buying mechanisms such as specific clientelistic practices, patronage networks, welfare policies, and/or coercion. At the same time, it seems that greed and grievance are more pronounced whenever resources lie in the hands of the state. Exploring the within-country variation, further analyses reveal that divergent welfare spending patterns are likely to be one causal channel driving the relationship between resource ownership and internal violence.     

The Muslim paranoia narrative in counter-radicalisation policy

With the rise of the Islamic State of Iraq and Syria (ISIS), the issue of radicalisation has loomed large in Western policy debates. Recent summits on countering violent extremism have sought to highlight the importance of undermining extremist narratives, mobilising moderate Muslims who oppose ISIS and working to address drivers of radicalisation. This article explores the ideological underpinnings of this approach. It focuses on what I call the “Muslim paranoia narrative”, a recurring feature of Western radicalisation discourse that helpfully captures its ideological commitments and their contemporary significance. Analysing its manifestation in American political culture, I argue that the Muslim paranoia narrative indicates a powerful process of ideological reproduction that works against approaches to counter-radicalisation centred on engagement and collaboration with Muslim communities.     

The changing political culture of the African National Congress

The early elite of the African National Congress (ANC) embraced values of moral improvement, individual responsibility and a sense of social consciousness. The ANC now governs South Africa, but with what appears to be a different set of principles. The current scourge of corruption, increasing state control, coupled with a general lack of service delivery point to behaviour of the ruling party which is inward-looking, self-seeking and self-preserving. Arguing that political culture and its accompanying values and attitudes is a prime motivator of behaviour, the paper seeks to understand the changing political culture of the dominant party. To understand the political culture of the ANC we use interviews with ANC parliamentarians and ANC supporters conducted in 2006–2007 and 2013 as well as an analysis of the ANC's Strategy and Tactics policy documents. We contend that the liberal values of the early elites were never fully embedded, but in their stead is a liberationist culture, where the state is normatively understood to be extensive and embodying the will of the people. We argue, that through the resulting centralized determination of the interests of the people, patronage networks, and diminishing of accountability, a system conducive to corruption and the pursuit of personal interest is created.
