Can the power of platforms be harnessed for governance?

Although not as eye-catching as their business counterparts, many public and private institutions are currently experimenting with using platforms as a strategy of governance. Governance platforms are now being constructed by a wide array of actors at different geographical scales and across a wide range of issue areas. Although often enabled by digital technology, governance platforms fundamentally embody a new organizing logic to achieve distributed participation and mobilization. While private platforms are transforming the way that companies create and market their products or services and shifting the fundamental logic of how value is produced and appropriated, can this powerful organizing logic be harnessed for public as well as private purposes? We investigate how governance platforms generate powerful effects and survey the extant literature on governance platforms. We conclude that governance platforms do demonstrate promise, although they face a number of challenges.     

Education Reform in Japan: A Course for Lifelong Learning

Japan's current education system has its origins in postwar reform, overemphasizing individualism and underemphasizing on Japan's history, traditions, and culture, resulting in the continuing decline in scholastic, physical, and socializing ability to date. This essay reviews the IIPS proposal on educational reform, which was supervised by former Prime Minister Yasuhiro Nakasone, with the addition of the author's personal views. The IIPS proposal set the ultimate goal of education in Japan to be raising healthy people who have self-confidence and pride as Japanese who can thrive in the era of globalization. Then, the proposal presents what a Japanese should learn and how he should serve at each life stage beginning with early childhood education through the compulsory education period, adolescence and young adulthood, maturity, and into the elderly period. Moreover, the organizational reform on administrating education policy is presented, with a focus on abandoning the current board of education system.     

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.     

Population Aging in Postwar Japan: Processes and Prospects

This paper critically reviews postwar population development in Japan and aims to identify unsolved issues, which are possibly shared by other countries, and extract lessons for the future. First, I examine long-term development on fertility and life expectancy in Japan with a brief introduction of pre-war population history. I stress that some critical issues have often been ignored in policy debates and some important new challenges are now emerging, factors that are indispensable to extract lessons for the future. Second, I turn to the official population projections and related issues which again require scrutiny. Third, I emphasize that serious scientific investigation from multiple disciplines is essential to cope with the challenges of demographic changes and that Japan should take the leading role in research for the next generations all over the world.     

Computer-assisted skull identification system using video superimposition

This system consists of two main units, namely a video superimposition system and a computer-assisted skull identification system. The video superimposition system is comprised of the following five parts: a skull-positioning box having a monochrome CCD camera, a photo-stand having a color CCD camera, a video image mixing device, a TV monitor and a videotape recorder. The computer-assisted skull identification system is composed of a host computer including our original application software, a film recorder and a color printer. After the determination of the orientation and size of the skull to those of the facial photograph using the video superimposition system, the skull and facial photograph images are digitized and stored within the computer, and then both digitized images are superimposed on the monitor. For the assessment of anatomical consistency between the digitized skull and face, the distance between the landmarks and the thickness of soft tissue of the anthropometrical points are semi-automatically measured on the monitor. The wipe images facilitates the comparison of positional relationships between the digitized skull and face. The software includes the polynomial functions and Fourier harmonic analysis for evaluating the match of the outline such as the forehead and mandibular line in both the digitized images.     

Determination of Both Fetus’ and Mother's Blood Type from an Autopsy Case Immersed in Formalin for Over 50 Years

A female fetus which had been immersed in formalin for more than 50 years was found in Japan. Because no liquid blood could be obtained, we tried to use immunohistochemistry (IHC) methods to tissue samples obtained at autopsy to identify both the fetal and mother's blood type. We detected B antigens on endothelial cells in paraffin sections of the fetal organs. Furthermore, we observed both anti‐A‐ and anti‐B‐positive red blood cells in the intervillous space, which is indicative of the mother's blood type. To our knowledge, this is the first case report on determining the blood type of both the fetus and the mother from tissue immersed in formalin for such a long time. The results suggest that IHC is valuable for the determination of ABO blood type in circumstances of long postmortem duration and unfavorable storage conditions.     

Fatal poisoning due to ingestion of boiled oleander leaf extract

Nerium oleander is an ornamental evergreen shrub belonging to the family Apocynaceae. The Apocynaceae family includes the attractive evergreen shrub known as oleander. The cardiotoxic glycoside, oleandrin, is present in all portions of the common oleander plant. Oleander consumption can result in deadly situations accidentally or as a suicide attempt. After consuming kettle-boiled oleander leaf extract as part of a suicide attempt, an 80-year-old man was discovered comatose in his home and taken to our emergency room. The patient's heart rate was 30 beats per minute, and he had hypotension. Arterial blood gas analysis revealed remarkable metabolic acidosis and hyperkalemia (K: 7.7 mEq/L). An electrocardiogram showed a wide QRS wave, similar to a sine curve. The patient collapsed following cardiac arrest soon after hospital arrival. Veno-arterial extracorporeal membrane oxygenation was initiated; however, the patient eventually died. The serum level of oleandrin at hospital arrival, subsequently measured by LC–MS/MS, was found to be 33.4 ng/mL, far above the levels reported in previous fatal cases.     

An autopsy case of intraoperative death due to pulmonary fat embolism--possibly caused by release of tourniquet after multiple muscle-release and tenotomy of the bilateral lower limbs

Acute interstitial pneumonitis (AIP), also known as Hamman-Rich syndrome, is a distinct type of idiopathic interstitial pneumonia affecting patients of both genders without pre-existing lung diseases. We describe the case of a fulminant form of AIP and discuss the pathophysiological mechanisms of AIP with reference to the histological pattern. A 15-year-previously-healthy male boy presented to the Hospital with a 6-day history of malaise, fever and cough. The clinical prodromes were followed by the acute onset of increasing shortness of breath rapidly progressing in acute respiratory failure. Chest X-ray demonstrated bilateral diffuse airspace opacification; the high resolution CT confirmed the presence of bilateral, symmetric diffuse ground-glass attenuation. The patient was admitted to the intensive care unit, but died after few hours. An autopsy was performed within 24h. The histological examination of lung specimens showed a pattern of diffuse alveolar damage. immunohistochemical, microbiological and toxicological tests were also carried out. The clinical presentation, the histological findings and the exclusion of infective, traumatic, toxic and metabolic causes of acute respiratory distress syndrome (ARDS) allowed us to conclude that the boy was affected by AIP. In conclusion, AIP is a diagnosis of exclusion. It has a mortality rate ranging about 50%, despite mechanical ventilation. In fatal cases of AIP diagnosis can be based on clinical presentation, radiological, histological and microbiological findings and can be further confirmed by immunohistochemical analysis.     

An autopsy case of sudden death due to acute gastric dilatation without rupture

We report the first autopsy case of fatal gastric dilatation without rupture. A 31-year-old woman who lived alone was found dead in her living room. Despite being very thin, she showed marked abdominal distention. Autopsy and histological findings revealed that a severely distended stomach, of which walls notably thin and displayed transmural necrosis, occupied the entire abdominal cavity. Severe congestion was observed in the intestine and cecum. Theses findings suggest that bulimia nervosa together with anorexia nervosa resulted in rapid dilation of the stomach. We conclude that the cause of death was acute circulatory failure from hypovolemic shock that occurred following compression of the inferior vena cava and superior mesenteric vein, and by loss of circulatory volume to the third space.
