Frequency and Clinical Features of Patients who Attempted Suicide by Hara‐Kiri in Japan

Hara‐kiri is a unique Japanese custom, primarily stemming from the manners and customs that a samurai held. The aim of the present study was to investigate the clinical features of individuals who attempted suicide by hara‐kiri. We enrolled 647 patients who had attempted suicide. Clinical features were compared between those who had employed hara‐kiri and those who had used other methods. 25 of the 647 subjects had attempted suicide by hara‐kiri. The ratio of men to women and the proportion of patients with mood disorders were significantly higher in the hara‐kiri group than in the other methods group. The average length of stay in either the hospital or in the intensive care unit was also longer in the hara‐kiri group than in the other methods group. Hara‐kiri is an original Japanese method of attempting suicide, and suicide attempts by hara‐kiri may be aimed at maintaining a reputation or taking responsibility.     

Matching goods and people: aid and human security after the 2004 tsunami

This article asks why, despite an abundance of aid materials and the good intentions of various relief agencies, tsunami-relief efforts in Thailand after the Great Sumatra Earthquake of 2004 resulted in complaints and skewed aid distribution. Beginning with an analysis of how relief goods are distributed in practice, the focus of the article shifts to forces that cause certain types of goods to be concentrated in certain communities. It concludes by identifying the limits of the goods-based relief approach, introducing intangible resources and identity as more foundational dimensions in the study of distribution.     

从三个“谁”的角度分析中国国有公司治理——鉴于日本的失败经验

在日本,公司治理的效力很早以前就成为较大的问题,很多人认为日本的许多经营者监督机制并没有发挥应有的作用,而是存在很多漏洞,这是因为日本的法律和现实情况之间存在很大的距离,比如日本的法律规定股东大会选任监事和董事,董事会和监事对董事或者代表董事进行监督,而在现实情况中,社长把握着极大的权力,可以选任自己的部下作为监事和董事,甚至在退休之后都可以垂帘听政。因此,20世纪90年代以后,日本引进了美国式的公司治理制度,但是这种公司治理制度改革不能认为是很成功的,以日本的失败经验为基础分析中国大型国有公司的公司治理问题很有参考价值,这就是日本没有从三个"谁"的视点进行改革。     

Classification system of frontal sinus patterns by radiography. Its application to identification of unknown skeletal remains

Frontal sinuses of Japanese skulls were radiographically examined from the view point of identifying individuals. The system of classification of sinus was proposed, basing on the area size, the bilateral asymmetry, the superiority of side, the outline of upper borders, the partial septa and the supraorbital cells. Frontal sinus patterns could be divided into above 20,000 possible combinations by combining the class numbers in each classification item described above. The frontal sinus pattern of a given person was formulated as a code number which was determined by arranging the class numbers in each classification item as serial numbers. This identification system by the frontal sinus pattern should allow one to characterize each person. The application of this identification system to an actual criminal case was also described.     

A rare fatal case of silicone resin precursor (SH792) poisoning.

A 39-year-old man committed suicide by ingesting a large quantity of SH792. SH792 is a silicone resin precursor used as a hardener for waterproof paints. It is polymerized in water; this process is then followed by the formation of silicone resin and the release of N,N-diethylhydroxylamine. In this decedent, analysis by infrared spectroscopy showed that polymerized silicone resin was present in the stomach contents. The amount of silica in his tissues was within levels seen in control subjects. N,N-diethylhydroxylamine was detected in the urine (0.7 microliters/ml) but not in the stomach contents. The data suggest that SH792 was polymerized in the stomach and the released N,N-diethylhydroxylamine (DEHA) was absorbed into the body. The mechanism of SH792 poisoning is also discussed.     

The Changing Structure of Communist Party Membership in Urban China, 1988–2002

This paper examines changes in the membership structure of the Communist Party of China during the 1990s. It concentrates on urban China to investigate the relationship between socioeconomic characteristics of the region (city) and the age, educational, and occupational structures of the regional party. The major findings are as follows. First, the development of marketization has widened opportunities for the younger generation to achieve socioeconomic success outside party membership. Second, the younger generation's incentives for joining the party have consequently been increasingly important determinants of the party's membership structure. Third, the subsequent technocratic reorganization of the urban party seems to have progressed through the conventional bureaucratic-elite path in the government and publicly owned sectors rather than through the newly emerging qualified professional-elite path.     

Usefulness of a toothbrush as a source of evidential DNA for typing

We investigated the usefulness of a toothbrush as a source of DNA for an unidentified cadaver. Ten toothbrushes were obtained from ten individuals along with their peripheral blood. We recovered from 10 to 430 ng of DNA from all but one of the toothbrushes. All ten toothbrushes, including the one containing no detectable DNA by fluorometry, were typed correctly at all of the loci tested, including nine STRs. Three toothbrushes obtained in two actual deaths also identified two victims and one suspect. Therefore, toothbrushes seem to be useful as a source of evidential DNA for personal identification.     

Statistical comparison of dog and cat guard hairs using numerical morphology

Numerical features obtained from the guard hairs of dogs and cats (total 300 hairs per dog or cat) were statistically compared, in an attempt to discriminate between them. Using hairs from each of five mongrel dogs and cats, eight measurements (length (Len), maximum width (MaxWid), cross sectional maximum diameter, cross sectional minimum diameter, cuticular thickness of the cross section and three scale counts per 100 microm length (observed at three positions: distal third (disSC), middle (midSC) and the proximal third (proSC) portions) and five indexes (hair width index (HWI), medulla index (MI), hair index, cuticle index and the difference in scale counts between the distal and proximal parts (defSC)) were examined. The range for each numerical feature overlapped each other extensively, and none of the features permitted a discrimination between dog and cat hairs, based on the values obtained. However, 12 numerical features, except for the midSC, showed a statistically significant difference between dog and cat hairs, as evidenced by a t-test. For the purpose of comprehensively comparing numerical features and statistically discriminating between dog and cat hairs, a discriminant analysis between the two were carried out using a multiple regression analysis. Four types of discriminant functions produced by combining over five numerical features were examined. Dog and cat hairs could clearly be discriminated using any of the discriminant functions. Species discrimination using the discriminant function permitted the species of a dog or cat to be determined, based on the overall morphologies of various numerical features. When experimentally collected test samples were investigated using the discriminant function using Combination-2, consisting of eight numerical features (Len, MaxWid, MI, HWI, disSC, midSC, proSC and defSC), all 10 cat hairs were correctly determined to be cat hair and 22 of 23 dog hairs were correctly identified. This discriminant function produced good results for species discrimination between dog and cat hairs.     

Central nervous system consequences of an unusual body disposal strategy: case report and brief experimental investigation

The body of a 73-year-old man was dismembered by his female companion for the purpose of covert disposal. The method employed included skillful separation of body parts with hacksaw and knife, piecemeal disposal of fragments, and prolonged boiling of the decapitated head. The latter treatment resulted in marked shrinkage of cranial dura mater, separation of dura mater from skull, and extrusion of brain fragments into the resultant enlarged epidural space through a dural defect due to the disproportionately greater shrinkage of dura mater compared to brain parenchyma. This resulted in curd-like brain fragments filling an enlarged epidural space and overlying a shrunken, leathery dura mater. The cranial dura mater, still adherent to the skull base, resembled a "shrunken brain" in contour but contained only the remnants of brain tissue not already extruded through the dural defect. This unusual thermal artifact is rarely illustrated or mentioned in forensic literature. The development of this postmortem artifact likely requires the presence of a specific combination of conditions which must be, but apparently rarely are, simultaneously present.     

Preliminary study of hair form of Japanese head hairs using image analysis

The use of average curvature measurements for the forensic comparison of curly hairs has been reported, but a method, in which various types of hair form are quantitatively examined and objectively interpreted for hair comparison, has not been reported to date. In the present study, numerical data on hair form from Japanese subjects were obtained by image analysis and a morphological comparison of these head hairs was investigated. Head hairs obtained from eight Japanese males were measured for length (L), distance (D) and area (A) using a Kontron Imaging System KS400. From the three measurements mentioned above, three indexes, L/D, A/D and 2(A/L), were examined. The inter-individual variations for each value were investigated by a t-test and the availability of six values for the forensic comparison of hair form was evaluated by a stepwise linear discrimination analysis. Six values obtained from hair form by an image analysis showed large intra-individual variations. However, these six values were found to be useful for discriminating between two individuals, since the six values showed larger inter-individual variations than intra-individual variations. Discrimination on each comparison using a stepwise linear discrimination analysis was performed for some of the values and the results indicated conspicuous inter-individual variations between the two individuals. On 11 of 28 comparisons, 30 hairs from one individual could be completely distinguished from hairs of another individual, when a two-way comparison was employed. These results confirm that hair form could be quite useful in the forensic comparison of hair morphology, and suggest that numerical data obtained from hair form by image analysis are very important values for constructing a screening procedure for evidential hairs. The use of an objective measure of hair form will be especially useful for Japanese head hairs since they are generally thought to show very limited variation in morphological features.
