Accidental hanging by a sweater: an unusual case

An accidental atypical hanging with the collar of a sweater is reported. A 67-year-old man was found dead in the sitting position with the collar of his sweater hanging off the brake handle of a motorcycle. Autopsy findings revealed a ligature mark on the surface of the neck; hemorrhages in the sternohyoid muscles; submucosal hemorrhages in the left greater horn of the hyoid bone; a large degree of submucosal petechial hemorrhages in the larynx, oral mucosa, and palpebral conjunctivae; and dark-red liquid blood with little clotting in the heart cavities. The alcohol levels in the blood and urine were 2.84 mg/ml and 3.52 mg/ml, respectively. It was concluded that the man had died from hanging by the sweater, and it was speculated that when he became inebriated, he might have lost consciousness and then fell with the collar of his sweater hanging from the brake handle of the motorcycle.     

Dental identification using digital images via computer network

Dental identification is a useful scientific method. In Japan, however, there are only a few forensic odontologists; moreover, until now, forensic dental services have only been offered by general dentists. These dentists may not be able to offer such forensic services during office time. For a quick comparison, the authors tried sending digital photos, taken with a 2-million-pixel digital camera, to dental offices via the Internet. If a dental office has Internet access, it is possible for dental charting to be sent directly to the autopsy room. Of course, digital images only provide the first outline. However, when antemortem dental records of the person in question are available at autopsy, a quick comparison can be made.     

Positive and negative ion mass spectrometry of tricyclic antidepressants

Positive electron impact (EI), positive chemical ionization (CI), and negative CI mass spectra of eight tricyclic antidepressants are presented. In the positive EI mode, peak(s) at m/z 193 and/or 195, which corresponded to the tricyclic nucleus, appeared for five compounds; a peak at m/z 58 was common to compounds having a gamma-dimethylaminopropyl group as their side chain. Molecular ions appeared for all compounds though they were very small in some compounds in the positive EI mode. In the positive CI mode, [M + H]+ quasi-molecular peaks appeared together with [M + C2H5]+ peaks in five compounds; the ion at m/z 196, which corresponded to the tricyclic nucleus also appeared in five compounds. In the negative CI mode with 1 Torr chamber pressure, [M - 1]- quasi-molecular ions were observed for all compounds except for lofepramine; [M + 43]- anions, which probably corresponded to [M + C3H4]-, appeared in five compounds; strong [M + Cl]- ions appeared in carpipramine and clocapramine. The anions due to the tricyclic nucleus also appeared in this mode. In the negative CI mode at low pressure (0.01 Torr), the spectra were generally similar to those in the 1 Torr negative CI mode. However, the cluster anions never appeared at the low pressure. Some data on extraction for some antidepressants from human urine and plasma, and their separation by gas chromatography, are also presented.     

Japanese Labour Unions and Nuclear Energy: A Historical Analysis of Their Ideologies and Worldviews

This article analyses how diverse stances toward nuclear energy were produced and reproduced among Japanese labour unions from the mid-1960s to the mid-1980s, and how these stances of the formative period influenced the subsequent development of inter-union politics before and after the Fukushima nuclear plant disaster in 2011, based on content analysis of union bulletins and other materials of pro- and anti-nuclear energy unions. This article asks three research questions: (i) what factors contributed to pro- or anti-nuclear energy stances of labour unions?; (ii) what elements constituted or framed unions’ arguments on the issue of nuclear energy?; and (iii) what impact did these stances and arguments formed in the early period have on the subsequent development of inter-union politics over nuclear energy, especially in the aftermath of the Fukushima nuclear disaster? The paper shows union ideologies and institutional integration were the factors influencing unions’ stances on nuclear energy. It also analyses the worldviews of pro- and anti-nuclear energy unions based on the three policy styles of technological enthusiasts, moralists and cost-benefiters. The Fukushima disaster reinforced the previously formed division of union ideologies, but considerably weakened the discourse of technological enthusiasm stressed by pro-nuclear energy unions.     

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.     

Direct and non-linear innovation effects of demographic shifts

A varied set of pressures drive organizational innovation. Among these pressures, demographic shifts seem to boost innovation, as the public sector responds to the arrival of migrants and to community changes in race and ethnic composition. However, we know little about innovation by governments in response to expected population decline. In particular, studies have under-examined how anticipated demographic pressures prompt public organizations to innovate. This study undertakes this task by arguing that innovation is more visible in municipalities facing greater anticipated demographic decline. However, we also argue for a non-linear relationship in which too strong and/or too weak expected demographic declines lead to less visible innovation (inverted U-shape effect). These propositions were tested with a data set of Japanese municipalities and employing a dose–response model. Findings show that anticipated demographic declines directly boost innovation visibility. However, too strong and/or too weak unexpected demographic declines make innovation less visible.     

Ethnicity,political survival,and the exchange of nationalist foreign policy

How does leadership’s desire for political survival in ethnically heterogeneous democracies affect the probability of states exchanging nationalist foreign policy? I define nationalist foreign policy as foreign policy that aims to fulfill national self-governance using a civic or ethnic frame. I argue that civic-nationalist policy disputing the territoriality of one’s own state is more likely, while ethno-nationalist policy favoring the leadership’s foreign co-ethnics is less likely, when the size of the leadership’s ethnic group is small and the level of democracy is relatively high. This is because the leadership, under such domestic conditions, has to mobilize support from other ethnic groups in order to stay in power. Civic-nationalist policy allows the leadership to increase domestic solidarity across ethnic lines and mobilize support from other ethnic groups, whereas ethno-nationalist policy would risk other ethnic groups criticizing the leadership of being ethno-centrist. These hypotheses are supported by quantitative analysis using an original dataset.     

Gender and Corruption in Business

Are firms with female owners or managers less corrupt than other firms? We test this question using firm-level data on corruption, ownership, and management. We find that women in positions of influence are associated with less corruption: female owners are associated with a lower incidence of bribery and report smaller levels of bribery. Moreover, corruption is seen as less of an obstacle in companies where women are represented in top management. By providing evidence that women are associated with lower levels of corruption in business our research contributes to the literature on development, gender equality, and corruption.     

What Drives Japanese INGOs to Operate in Latin American Countries?

International nongovernmental organizations (INGOs) provide essential aid and public services to less-developed countries. Although most literature focuses on Western INGOs, Asian INGOs have also become globally active. Little is known about what motivates INGOs to provide services in other regions, such as Latin America. In this study, we seek to identify the criteria Japanese INGOs use to select Latin American recipient countries. We propose that Japanese INGO operational location decisions are a function of Japanese foreign policy agenda, Japan-recipient country business relations, and recipient country’s need and liberalization. Using data from Japanese INGOs working in Latin America and 24 Latin American countries on contextual, macroeconomic, and demographic indicators, we find that the significant factors driving INGO decisions to operate in Latin American countries are need and the presence of Japanese businesses in the recipient country. Results have practical implications for foreign aid targeting and economic development.
