Maritime Security in the Region: SCS and ECS as Key Arenas for Converging Political Interests

This article examines the situations in the South China Sea (SCS) and East China Sea (ECS) and the reasons for recent political and strategic attention. As background it reviews the history of maritime activities in Asia where there was no real maritime Great Power with continuity. It then discusses the latest situations in the ECS around the Senkaku Islands, where China's Coast Guard vessels and fishing boats have made occasional incursions into Japanese waters, and the relatively-less understood Scarborough Shoal and the Pratas Islands in the SCS that have strategic significance in a future powerbalance in the SCS. The article then notes the US rebalance to Asia and the interpretation of the principle of Freedom of Navigation. It continues with the strategic and diplomatic measures and operational and tactical measures that Japan should take. It concludes noting that Japan and the US must prepare a wide range of measures in advance to regain and maintain maritime security and stability.     

Simple and Sensitive Method for Identification of Human DNA by Allele-Specific Polymerase Chain Reaction of FOXP2

Abstract:  The forkhead box P2 ( FOXP2 ) gene is specifically involved in speech and language development in humans. The sequence is well conserved among many vertebrate species but has accumulated amino acid changes in the human lineage. The aim of this study was to develop a simple method to discriminate between human and nonhuman vertebrate DNA in forensic specimens by amplification of a human-specific genomic region. In the present study, we designed an allele-specific polymerase chain reaction (PCR) using primers to amplify smaller than 70-bp regions of FOXP2 to identify DNA as being of human or nonhuman, including ape, origin. PCR amplification was also successfully performed using fluorescence-labeled primers, and this method allows a single PCR reaction with a genomic DNA sample as small as 0.01 ng. This system also identified the presence of human DNA in two blood stains stored for 20 and 38 years. The results suggested the potential usefulness of FOXP2 as an identifier of human DNA in forensic samples.     

Fatal subarachnoid hemorrhage complicating actinomycotic meningitis

Actinomycosis is caused by Gram-positive Actinomyces species that are part of the normal oral flora with low virulence. We describe a rare case of sudden death of a 48-year-old man with actinomycotic basilar meningitis that was complicated by fatal subarachnoid hemorrhage. Autopsy revealed meningitis at the basilar region of the brain, and histological examination revealed characteristic bacterial aggregates with extensive leukocyte infiltration and severe vasculitis of arteries of this region. Rupture of an artery by severe arteritis was thought to be the cause of the subarachnoid hemorrhage. The probable primary source of infection was found in the left lung. To the best of our knowledge, the complication of subarachnoid hemorrhage has not been reported previously in actinomycotic meningitis.     

Polymorphisms of eight STR loci in Chinese and African (Xhosa)populations

Allele frequencies for eight short tandem repeal loci (D16S539, D7S820, D13S317, D5S818, CSF1PO, TPOX, TH01 and vWA) were obtained from samples of 100 Chinese and 96 African (Xhosa) unrelated individuals.     

Effects of a Dog-Assisted Intervention Assessed by Salivary Cortisol Concentrations in Inmates of a Japanese Prison

Physiological effects of a dog-assisted, stress management and communication training program conducted in a prison were investigated by assessing salivary cortisol concentrations of prison inmates before and after the sessions. The program was conducted with groups of inmates with psychiatric and/or developmental disorders. In the program, male inmates interacted with trained pet dogs and their volunteer handlers. Inmates evaluated their mood states before and after each session by using a questionnaire. Moreover, handlers evaluated the quality of the interaction with inmates after each session. Results indicated that the inmates’ cortisol values in most cases decreased following their participation in the sessions. The inmates who demonstrated stress reduction by decreasing cortisol values were diagnosed only psychiatric disorders, were aware of their mood improvement, and were evaluated by the handlers as having interacted well during the sessions. This indicated the validity of psychiatrists’ diagnoses, inmates’ self-evaluation, and handlers’ evaluation of inmates. Also, inmates who experienced a medium mood without mood changes had decreased cortisol values. It is suggested that these results are useful for predicting and selecting inmates who are expected to obtain effects by participating in the program. Moreover, it is suggested that providing feedback to inmates about changes in their salivary cortisol levels could help them better understand their psychophysical state, which could result in more effective stress management.     

The Impact of Adult Mortality and Parental Deaths on Primary Schooling in North-Western Tanzania

Mortality of parents and other adults due to the African AIDS epidemic could reduce children's primary schooling by reducing households' ability to pay fees, raising the opportunity cost of children's time, and leaving orphaned children with guardians who care less about their education than would their parents. This study measures the impact of adult deaths and orphan status on primary school attendance and hours spent at school using a panel household survey from north-western Tanzania, an area hard-hit by the AIDS epidemic. Attendance was delayed for maternal orphans and children in poor households with a recent adult death; there was no evidence that children 7-14 dropped out of primary school due to orphan status or adult deaths. However, among children already attending, school hours were significantly lower in the months prior to an adult death in the household and seemed to recover following the death. In addition, girls sharply reduced their hours in school immediately after losing a parent. Improvements in school quality and better access to secondary education would improve outcomes for all children, including those affected by adult AIDS mortality. Beyond that, public policy needs to focus on the special schooling constraints faced by children affected by adult deaths, both in terms of increased opportunity costs of their time and the psychological impacts, with an eye to how they might be mitigated and at what cost.
