Australia and Japan's Admission into the Colombo Plan

In October 1954 Japan was admitted to the Colombo Plan as a donor country with Australia's sponsorship. The dramatic shift in Australia's position on Japan's involvement in the Colombo Plan, from strong opposition to sponsorship, was recognised by the Japanese government as the first Australian initiative to improve the bilateral relationship since the resumption of diplomatic relations in April 1952. This article examines Japan's attempts to participate in the Colombo Plan and considers how Australia's actions and reactions determined the course of events. The episode provides an insight into how Australian diplomacy was conducted towards Japan and the Japanese view of its relations with Australia at the initial stage of the bilateral relationship.     

Simultaneous determination of eight catechins and four theaflavins in bottled tea by liquid chromatography-tandem mass spectrometry for forensic analysis

Tea, and particularly bottled tea, is widely consumed worldwide and is often encountered at crime scenes in poisoning cases or used in place of urine in drug abuse monitoring. Tea is a rich source of polyphenols, such as catechins and theaflavins, and these compounds are useful for identification of trace quantities of tea samples. However, information on the contents of catechins and theaflavins in bottled tea is limited. In this study, a method was developed for simultaneous analysis of eight catechins and four theaflavins in tea using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The concentrations of these polyphenols were determined in bottled black, oolong, and green teas after a simple pretreatment process by the standard addition method. The developed LC-MS/MS method was rapid and all tested polyphenol compounds were separated within ~14 min. All tea types contained all the catechins, at varying concentrations, but not all the theaflavins were present in all the tea types. This indicates that the theaflavin composition reflects the degree of the fermentation and could be used for discrimination among different types of tea. All the green tea samples contained all eight catechins; however, the concentrations of these compounds varied among the tea samples. Principal component analysis and hierarchical cluster analysis were useful for discrimination of samples. It has been unclear whether the variations of chemical components are useful for forensic discrimination. Our results demonstrate that, in addition to identification of tea varieties, catechins and theaflavins can be used for the discrimination of bottled tea samples.     

The advocacy coalition framework in Japan: Contributions to policy process studies and the challenges involved

The advocacy coalition framework (ACF), a unified framework for understanding the policy process, has been applied in various countries and regions; however, there are few contributions from Japan, despite seemingly favorable conditions for applying it. An exploration of what hinders ACF applications in Japan is worthwhile for developing the ACF as a framework for comparative policy process studies across various social and political settings. Therefore, this study aims to systematically review previous Japanese ACF studies. Our review found that Japanese ACF studies are fewer in number, have less coverage of policy fields, and have less methodological diversity and transparency than international trends. While most of the Japanese ACF studies supported the basic hypotheses of the ACF, we found a need to refine some hypotheses and research methods of the ACF studies. We also discuss the background factors in the inactivity of ACF studies in Japan and suggest solutions for it.     

Differential rigor development in red and white muscle revealed by simultaneous measurement of tension and stiffness

Based on the molecular mechanism of rigor mortis, we have proposed that stiffness (elastic modulus evaluated with tension response against minute length perturbations) can be a suitable index of post-mortem rigidity in skeletal muscle. To trace the developmental process of rigor mortis, we measured stiffness and tension in both red and white rat skeletal muscle kept in liquid paraffin at 37 and 25 degrees C. White muscle (in which type IIB fibres predominate) developed stiffness and tension significantly more slowly than red muscle, except for soleus red muscle at 25 degrees C, which showed disproportionately slow rigor development. In each of the examined muscles, stiffness and tension developed more slowly at 25 degrees C than at 37 degrees C. In each specimen, tension always reached its maximum level earlier than stiffness, and then decreased more rapidly and markedly than stiffness. These phenomena may account for the sequential progress of rigor mortis in human cadavers.     

Age estimation using cytochrome c oxidase activity analysis

Recently, in the field of forensic medicine the number of unidentified cadavers has increased due to mass disasters and international terrorism. In addition to the conventional anthropological methods, a simple and precise method to estimate the age of these unidentified cadavers to assist in the personal identification is necessary. On the other hand, many researchers have reported that mitochondrial respiratory activity decreases with aging because of the production of reactive oxidative species in the process of ATP generation. Therefore, it may be possible for us to estimate human age by analyzing mitochondrial activity. In this report we attempted to analyze cytochrome c oxidase (CCO) activity, and the amount of protein and mRNA expression in various aged rats. The age of human subjects was estimated through the analysis of human CCO activity from 28 actual forensic cases. The CCO activity, the amount of protein and the mRNA expression increased in the 3rd week and decreased afterwards in rats. Furthermore, human CCO activity was decreased gradually with aging. Therefore, CCO activity analysis may be useful for age estimation in forensic cases.     

Praj?��karagupta on the Two Truths and Argumentation

How is it possible to say that truth can be of one kind at the conventional level and totally different in the ultimate plane? As Matilal (1971, p. 154) points out, Kum??rila (ca. 600?C650), a M??m???saka philosopher, claims that the Buddhist doctrine of two truths is ??a kind of philosophical ??double-talk??.?? It is Prajñ??karagupta (ca. 750?C810), a Buddhist logician, who tries to give a direct answer to this question posed by Kum??rila from the Buddhist side. He argues that even a M??m???saka cannot demonstrate the validity (pr??m???ya) of the Veda without accepting two truth levels. His point is this. Consider the proposition to be proved: the Veda is valid. If the Veda is already known as valid, then it is useless to prove this proposition. But if it is already known as invalid, then it is impossible to prove this proposition. Therefore in the argument to prove the proposition, the Veda is not to be regarded either as valid or as invalid. This means that at the first stage of the argument one has the concept of the Veda as neutral in validity. However, as soon as one acquires the knowledge of the Veda as valid through the argument, one has to repudiate such a conception of the Veda. The acceptance of the Veda as neutral in validity is to the acceptance of the Veda as valid as the conventional truth is to the ultimate truth.     

新MEGA在亚洲编辑的可能性及其课题

MEGA和《著作集》完全不是一个概念。《著作集》只关心最终的文本,但是新MEGA是将马克思恩格斯所遗留下来的全部文献遗产毫无遗漏地变成活字。新MEGA最终出版得益于1990年"国际马克思主义基金会"的成立。此后日本学者参加其中两卷的编辑工作,并致力于对《资本论》阶段"马克思恩格斯问题"的解析。相信清华大学和北京大学精英的加入,会让以新MEGA为基础的马克思恩格斯研究在亚洲生根发芽。     

Development of heavy mineral and heavy element database of soil sediments in Japan using synchrotron radiation X-ray powder diffraction and high-energy (116 keV) X-ray fluorescence analysis: 1. Case study of Kofu and Chiba region

We have started the construction of a nationwide forensic soil sediment database for Japan based on the heavy mineral and trace heavy element compositions of stream sediments collected at 3024 points all over Japan obtained by high-resolution synchrotron X-ray powder diffraction (SR-XRD) and high-energy synchrotron X-ray fluorescence analysis (HE-SR-XRF). In this study, the performance of both techniques was demonstrated by analyzing soil sediments from two different geological regions, the Kofu and Chiba regions in Kanto province, to construct database that can be applied in the future to provenance analysis of soil evidence from a crime scene. The sediments from the quaternary volcanic lithology of the Chiba region were found to be dominated by heavy minerals of volcanic origin - orthopyroxene, clinopyroxene, and amphibole, and the REEs (rare earth elements) within the region showed similar geochemical behavior. On the other hand, four distinct heavy mineral groups were identified in the sediments of the Kofu region, where there is a great variety of underlying bedrock, and the geochemical behavior of the REEs in the sediments also varied accordingly to their geological origins. As such, our study shows that high-resolution SR-XRD data can provide information on the spatial distribution patterns of heavy minerals in stream sediments, playing an important role in determining their likely geographical origin. Meanwhile, the highly sensitive HE-SR-XRF data allow us to study the geochemical behavior of trace heavy elements, especially the REEs in the sediments, providing additional support to further constrain the likely geographical origin of the sediments determined by heavy minerals.     

Application of Postmortem 3D‐CT Facial Reconstruction for Personal Identification*

Abstract: Postmortem computed tomography (CT) images can show internal findings related to the cause of death, and it can be a useful method for forensic diagnosis. In this study, we scanned a ready‐made box by helical CT on 2‐mm slices in a mobile CT scanner and measured each side of the box to assess whether reconstructed images are useful for superimposition. The mean difference between the actual measurements and the measurements on the three‐dimensional (3D) reconstructed images (3D‐CT images) is 0.9 mm; we regarded it as having no effect on reconstruction for the superimposition method. Furthermore, we could get 3D‐CT images of the skull, which were consistent with the actual skull, indicating that CT images can be applied to superimposition for identification. This study suggested that postmortem CT images can be applied as superimpositions for unidentified cases, and thinner slices or cone beam CT can be a more precise tool.
