Japan’s Diplomacy towards Member Countries of Pacific Islands Forum: Significance of Pacific Islands Leaders Meeting (PALM)

As an island country in the Pacific region, it is natural for Japan to have diplomatic relationships with neighboring island countries. By the early 1970s, Japan started to provide Official Development Assistance (ODA) to two individual island countries in the Pacific region, and, in the mid-1980s, when most of the island countries had achieved independence, Japan’s diplomacy expanded to additional countries. In 1985 then Prime Minister Yasuhiro Nakasone made an official visit to two of the island countries, and, in 1987, official policy expressing support for the Pacific island countries’ independence, regional cooperation, political stability, economic development, and people-to-people exchange was issued. In October 1997, the “Japan-SPF Summit Meeting” with participants of leaders from Japan and 14 South Pacific Forum member island countries/regions and government representatives of Australia and New Zealand was held in Tokyo. The 8^th Pacific Islands Leaders meeting held in May 2018 is symbolic of Japan’s diplomacy toward the Pacific Islands Forum member countries. This article is the author’s personal observation of Japan’s diplomacy toward Pacific Islands Forum member countries and the significance of Pacific Islands Leaders Meeting.     

Trace Elemental Analysis of Titanium Dioxide Pigments and Automotive White Paint Fragments for Forensic Examination Using High‐Energy Synchrotron Radiation X‐Ray Fluorescence Spectrometry*

Abstract: High‐energy synchrotron radiation x‐ray fluorescence spectrometry (SR‐XRF) utilizing 116 keV x‐rays was used to characterize titanium dioxide pigments (rutile) and automotive white paint fragments for forensic examination. The technique allowed analysis of K lines of 9 trace elements in 18 titanium dioxide pigments (rutile), and 10 trace elements in finish coat layers of seven automotive white paint fragments. High‐field strength elements (HFSE) were found to strongly reflect the origin of the titanium dioxide (TiO₂) pigments, and could be used as effective parameters for discrimination and classification of the pigments and paint fragments. A pairwise comparison of the finish coat layers of seven automotive white paint fragments was performed. The trace elements in the finish coat layers detected by the high‐energy SR‐XRF were especially effective for identification. By introducing the trace element information of primer and electrocoat layers, all the automotive white paint fragments could be discriminated by this technique.     

An autopsy report on a ruptured rudimentary horn (uterine anomaly) with ectopic pregnancy

The rudimentary horn is a rare developmental anomaly of the Müllerian duct. Ectopic pregnancy in the rudimentary horn is estimated to occur in one out of 76,000–150,000 pregnancies. A 30-year-old primigravida suddenly collapsed after 3 days of continuous abdominal pain. Emergency laparotomy revealed a massive intraperitoneal hemorrhage and fetal demise. The growth of the fetus after 19 weeks of gestation is believed to have caused the rudimentary horn rupture, thereby rapidly leading to hemorrhagic shock in the mother and ischemic death in the fetus. This is the first autopsy report on maternal death due to the rudimentary horn or other Müllerian duct anomalies, which emphasizes the need for forensic pathologists to consider this condition as a possible cause of unexpected death in fertile women. In addition, it is very important for clinicians to detect Müllerian duct anomalies by sonography during routine obstetric examinations, and promptly diagnose anomaly related ectopic pregnancies in women displaying symptoms of an acute abdomen, intraperitoneal hemorrhage, or shock in the emergency practice.     

Quantitative analysis of tropane alkaloids in biological materials by gas chromatography-mass spectrometry

A simple and rapid method for quantitation of tropane alkaloids in biological materials has been developed using an Extrelut column with gas chromatography-mass spectrometry (GC-MS). Biological materials (serum and urine) were mixed with a borate buffer and then applied to an Extrelut column. The adsorbed tropane alkaloids were eluted with dichloromethane before a GC-MS analysis. Atropine-d(3) was used as an internal standard. The extracted tropane alkaloids were converted to trimethylsilyl derivatives prior to GC analysis, to improve the instability of tropane alkaloids from heating and the property of them for a GC column. The recoveries of the compounds, which had been spiked to biological materials, were more than 80%. The GC separation of the derivatives from endogenous impurities was generally satisfactory with the use of a semi-polar capillary column. Tropane alkaloids showed excellent linearity in the range of 10-5000 ng/ml and the limit of detection was 5.0 ng/ml for biological materials. The present method is simple and more rapid than those previously reported, and was applied to a poisoning case. It is useful for the routine analysis of tropane alkaloids in cases of suspected tropane alkaloids poisoning.     

Immigrant Students’ Emotional and Cognitive Engagement at School: A Multilevel Analysis of Students in 41 countries

Central to student learning and academic success, the school engagement of immigrant children also reflects their adaptation to a primary institution in their new country. Analysis of questionnaire responses of 276,165 fifteen-year-olds (50?% female) and their 10,789 school principals in 41 countries showed that school engagement has distinct, weakly-linked cognitive and emotional components. Native students had weaker attitudes toward school (cognitive engagement) but greater sense of belonging at school (emotional engagement) than immigrant students or students who spoke a foreign language at home. Students with better teacher–student relationships, teacher support or a classroom disciplinary climate often had a greater sense of belonging at school and had better attitudes toward school than other students. While immigrant students often have solid attitudes toward school, teachers can help them feel a greater sense of belonging at school.     

Factors that contribute to the improvement in maternal parenting after separation from a violent husband or partner

The authors test the hypothesis that separation from a violent husband or partner improves maternal parenting in Japan and examine how childhood abuse history (CAH), experience of domestic violence (DV), mental health problems, husband or partner's child maltreatment, and other demographic factors affect maternal parenting after such separation. A self-administered questionnaire survey is conducted for mothers (n = 304) and their children (n = 498) staying in 83 mother-child homes in Japan to assess the mothers' CAH, DV experiences, current mental health problems, and exposure to a husband or partner's child maltreatment. The authors also assess maternal poor parenting (physical and psychological abuse, neglect, no playing, and no praise) before and after admission into the mother-child homes. The total poor parenting score (specifically for neglect, no playing, and no praise) significantly reduces after separation from a violent husband or partner (p = .001, paired t test). However, scores for psychological abuse significantly increase after admission (p < .001, paired t test). CAH, DV, and mental health problems are not associated with a reduced total poor parenting score after admission. Husband or partner's child maltreatment is independently significantly associated with a reduced maternal poor parenting score: A 10% increase in such maltreatment is associated with a 5% reduction in the poor parenting score after separation. Marital status also contributes to the score reduction: The reduction is less in married or divorced mothers than in those who did not marry the partner. Mother-child homes might be useful for improving maternal parenting. Further study is needed to elucidate the mechanism of the impact of separation from a violent husband or partner on maternal parenting.     

Gangs as contractors: the social organization of American Taiwanese youth gangs in Southern California

This paper examines the organizational structure and operations of Taiwanese organized crime and youth gangs in Southern California. In-depth interviews were used as the principle method of research. In contrast to transnational criminal conspiracy claims and the La Cosa Nostra model of vertically integrated organizations, our findings suggest that these criminal groups consist of discrete local Taiwanese youth gangs which operate as largely independent economic units that show no substantive and operational ties to criminal organizations in Taiwan. The formation of Taiwanese criminal organizations and gangs in Southern California is primarily governed by the availability of financial opportunities. Furthermore, both the inter-gang relations and intra-gang structures exhibit a distinct form of contractor arrangement which consists of market-like weak ties that are simultaneously circumscribed by the criminal embeddedness. We argue that that these economic weak ties, which seem to render conventionally understood criminal organizational boundaries administratively less meaningful, still function as an operationally significant governance mechanism of the organizational structures of American Taiwanese youth gangs. In addition, the paper discusses the implications that the embeddedness has on the somewhat paradoxical and incoherent organizational structure.
