Averting a Crisis between Japan and China: A New Way of Thinking

As relations between Japan and China change due to a paradigm shift that has occurred over the past few years, the need for a new security outlook and world view has emerged. In East Asia, the foundation for the relationship between Japan and China must be fairness and justice, and the rule of law. This article proposes ways that Japan and China can work to cultivate common ground that would bring forth the possibility of a new Japan-China relationship based on the “strategic reciprocal relationship” established in 2006.     

A novel multiplex PCR system consisting of Y-STRs DYS441, DYS442, DYS443, DYS444, and DYS445

We have developed a new sensitive multiplex PCR system consisting of five male-specific and polymorphic tetranucleotide STRs--DYS441 (GDB: 10013873), DYS442 (GDB: 10030304), DYS443 (GDB: 10807127), DYS444 (GDB: 10807128), and DYS445 (GDB: 10807129) on the Y chromosome. Fifty pg DNA per 10 microL reaction volume was required for the correct typing of five STRs. Using this system, the five Y-STRs were correctly typed from blood and semen stains that had been stored for several years at room temperature.     

DPRK Troop Dispatches and Military Support in the Middle East: Change from Military Support to Arms Trade in the 1970s

The DPRK now trades in arms with the Middle East. However, in the October War (1973) the DPRK first began military cooperation with the Middle East by sending troops and providing unrequited military support. This switch was made to win support within the UN from these Middle Eastern countries, and so to counteract the US presence in the UN. Failing this, the DPRK withdrew from the UN in 1976. The DPRK then turned to arms trading both to build up its foreign currency reserves and to help liberate developing countries from US control.     

Development of a Library Search‐Based Screening System for 3,4‐Methylenedioxymethamphetamine in Ecstasy Tablets Using a Portable Near‐Infrared Spectrometer

This is the first report on development of a library search‐based screening system for 3,4‐methylenedioxymethamphetamine (MDMA) in ecstasy tablets using a portable near‐infrared (NIR) spectrometer. The spectrum library consisted of spectra originating from standard substances as well as mixtures of MDMA hydrochloride (MDMA‐HCl) and diluents. The raw NIR spectra were mathematically pretreated, and then, a library search was performed using correlation coefficient. To enhance the discrimination ability, the wavelength used for the library search was limited. Mixtures of MDMA‐HCl and diluents were used to decide criteria to judge MDMA‐positive or MDMA‐negative. Confiscated MDMA tablets and medicinal tablets were used for performance check of the criteria. Twenty‐two of 27 MDMA tablets were truly judged as MDMA‐positive. Five false‐negative results may be caused by compounds not included in the library. No false‐positive results were obtained for medicinal tablets. This system will be a useful tool for on‐site screening of MDMA tablets.     

The Impact of COVID-19 Restrictions on Victim Advocacy Agency Utilization Across Pennsylvania

This brief report highlights the impact of the COVID-19 restrictions on the utilization of Victim Advocacy Agencies’ (VAAs’) services across Pennsylvania, using VAA utilization data from 2019–2020. VAA utilization data in this report were collected from 2019–2020 by the Pennsylvania Coalition Against Rape (PCAR). VAA utilization data were anchored to COVID-19 restriction timelines, defined by the Pennsylvania Office of the Governor. For each month, a percent change in VAA utilization (e.g., Jan 2020 utilization compared to Jan 2019 utilization) was calculated. A one-way ANOVA was run to assess whether the association between restriction phase and percent change in overall VAA utilization from 2019 to 2020 was statistically significant. A substantial decrease in VAA utilization was observed once lockdown restrictions were enacted, as well as a sustained decrease in utilization between 2019 and 2020. When restrictions were eased, an increase in service utilization was noted. This pattern of findings held for the three variables assessed: hotline utilization, new client, and medical accompaniments for FREs per month. The one-way ANOVA confirmed a statistically significant decrease in overall VAA utilization when comparing the most severe COVID-19 related restrictions to both pre-COVID and less severe restrictions. A variety of barriers (e.g., financial instability, loss of childcare, technology access, chronic physical proximity to abuser, hospital visitation restrictions, fears of contracting the virus) may result in decreased utilization of VAA services. Future research should investigate the relevance of potential causal mechanisms behind VAA utilization to help inform intervention approaches.

Abstract

In October 1986 the foreign ministers of Indonesia and Papua New Guinea (PNG) signed a Treaty of Mutual Respect, Friendship and Co-operation. Under the terms of this treaty the two countries have agreed not to threaten or use force against one another and not to cooperate with others in hostile or unlawful acts against each other or allow their territory to be used by others for such purposes. Provision is made also for consultation and negotiation in the event of any dispute. The treaty was hailed by President Suharto as “another milestone in the history of both countries,” while Papua New Guinea's prime minister, Paias Wingti, and foreign affairs secretary, Bill Dihm, said it would give direction for the future and inspire confidence in Papua New Guinea and its regional neighbors.     

Lower limits of detection of synchrotron radiation high-energy X-ray fluorescence spectrometry and its possibility for the forensic application for discrimination of glass fragments

Synchrotron radiation high-energy X-ray fluorescence (SR-XRF) analysis utilizing 75.5keV X-ray radiation from beam-line BL37XU at Super Photon Ring 8GeV (SPring-8), a third-generation synchrotron facility, was found to have advantages for forensic discrimination of glass samples. The lower limits of detection (LLD) for calibration curves were at the picogram level for Ba, Ce, and Sm and at the 10pg level for Sr, Zr, Sn, and Hf. The spectrum of NIST SRM 612 glass reference material demonstrated K-line peaks of 31 elements including rare-earth elements, and the relative standard deviations (R.S.D.) of all the measured elements except Ca were less than 9.7%. Fragments of collected sheet glass were used as samples for investigating the application of this technique to forensic analysis. Several trace elements such as Pb, Rb, Sr, Zr, La, Ce, and Hf were detected in the spectra of the samples, and these elements could be used as indexes to characterize the glass samples. But the "lower limits of detection (LLD)" of each element were not examined enough. In this report, these limits by synchrotron radiation X-ray spectrometry were clarified. By these results, this technique should provide an effective approach to the nondestructive discrimination of small glass fragments in the field of forensic science.     

Change and continuity in Japanese corporate reform

Abstract

Confronted with critical business situations in the late 1990s, Japanese firms began to tackle reforms in both corporate governance and human-resource management. These reforms advocated that Japanese firms shift from being organization-based to market-based corporations, similar to their US counterparts. However, the actual reform did not produce such an overall change but occurred with incremental and cumulative changes within the existing institutional framework. This article examines continuing changes in Japanese firms, and demonstrates that they are diversified into different directions as a result of gradual institutional change.

Indication and limitations of using palatal rugae for personal identification in edentulous cases

To explore the availability and the limitations of using the palatal rugae pattern in forensic practice for personal identification in edentulous cases, we set up an experiment, which involved 48 patients who had both old and new complete dentures and we observed their rugae. First, we made 48 pairs of maxillary casts from their old and new dentures and a further 50 maxillary casts from complete dentures at random, to use as variables. All the initial impressions taken from the mucosal surfaces of complete dentures were made from alginate impression materials, and the maxillary casts were made from hard dental plaster. Secondly, all 146 casts were trimmed so that all the areas except for the rugae area were removed. Subsequently, 50 examiners were given the 48 casts from the old dentures and were then asked to compare them with the other 98 casts for possible matches. The case numbers, which matched correctly, were recorded. The median percentage of correct matches among the 50 examiners was 94%, despite variations in their experience with forensic identification, and this accuracy does not differ significantly from that in dentate cases, as described in previous publications. The median percentage of correct matches among the 48 cases was 90%. Analyzing the incidence of obtaining a correct match in each case revealed that there were three major misleading shapes that could give rise to a low rate of correct matches; (1) severely low and poorly demarcated eminences of rugae, (2) change of palatal height, and (3) non-complex rugae pattern. These features are mainly due to the shape of the edentulous palate itself and rarely due to the dentures, and could lead to difficulties in finding unique points for use in matching rugae patterns. The results suggest that an appropriate selection of cases, taking into consideration the above misleading shapes, may establish an increased rate of accuracy for identification with this method, thereby bringing the percentage of correct matches closer to 100% in edentulous cases, which is also the percentage of correct matches previously reported in dentate cases.
