The Structure of Indigenous Food Crop Markets in sub-Saharan Africa: The Rice Market in Uganda

Using data obtained from a series of nation-wide market surveys in Uganda, this article attempts to document and assess the domestic rice market at all stages in the post-harvest marketing chain from the farm gate to metropolitan area retail outlets. The criteria used are quantities marketed, prices, marketing margins, marketing costs and net returns to traders. The results show that the regional rice markets are integrated into the national market and that on average little surplus is left for rice traders at all market stages if marketing costs are accounted for. The spontaneously developed indigenous crop market works reasonably well.     

Phases of Irrigation Development in Asian Tropics: A Case Study of the Philippines and Sri Lanka

Using data for the Philippines and Sri Lanka during the last five decades, we examine three phases of agricultural development experienced by the rice sector in insular countries in tropical monsoon Asia; the first was based on land opening, the second on new irrigation construction and the third on increasing the efficiency of the existing irrigated land base. We show that these sequential shifts were induced by changes in the relative profitability of the three major means of land development for increasing food production. Rehabilitation, water management improvement and better maintenance, which are important means of irrigation development in the latest phase, are under-invested, despite their high rates of return.     

Socially optimal liability rules for firms with natural monopoly in contestable markets

This article considers the problem of socially efficient liability rules for firms in contestable markets where natural monopoly prevails due to decreasing average cost. If the fixed cost that pushes the entry-limiting price above marginal cost is large relative to the level of external harm of firms, the negligence regime is socially superior to the strict liability regime. In the opposite case, the strict liability rule may be socially superior.     

Why did CPSU reform fail? The 28th Party Congress Reconsidered

This article considers the reasons for the failure to reform the Communist Party of the Soviet Union (CPSU), which was central to the Soviet collapse. Using a wide range of party and other archives, it challenges the conventional view that power was concentrated in the hands of a very conservative party apparat that was able to frustrate any attempt at reform. Focusing on the issue of party renewal at the 28th Party Congress of 1990, it argues that party reformers, including many party secretaries, made serious efforts to change a hierarchically organised vanguard party into a social democratic one at about this time. Their eventual failure was due more than anything else to the reformers' lack of an organised movement and Gorbachev's indecisiveness.     

An Autopsy Case of Acute Massive Hematochezia Caused by Superior Mesenteric Vein Thrombosis: A First Report in Forensic Medicine

Superior mesenteric vein thrombosis (SMVT) is an uncommon cause of intestinal ischemia and massive gastrointestinal bleeding. This report describes a man with alcoholic liver cirrhosis, who died of massive hematochezia due to SMVT. A medicolegal autopsy disclosed a thrombus at the superior mesenteric vein and hemorrhagic infarction of the bowel wall, an area also within the territory of the superior mesenteric vein. Liver cirrhosis, an enlarged spleen, and esophageal varices without rupture were also observed, but ulcers and variceal bleeding were not. Other organs showed no significant findings. His blood alcohol level was 0.14% w/v. Thus, this man died from severe hematochezia associated with SMVT due to liver cirrhosis and alcohol dehydration, which can lead to coagulopathy and rapid progress of thrombus formation. This is the first report on an alternate cause for massive gastrointestinal hemorrhage with a cirrhotic patient in a forensic autopsy.     

Why do states join US-led military coalitions?: The compulsion of the coalition's missions and legitimacy

Why do states join US-led military coalitions? The war/dispute-diffusionliterature suggests that opportunity and willingness are crucialdeterminants of coalition participation (Siverson and Starr, 1990,1991). A state joins a coalition if it has a strong interestin war and enough capability to send armed forces abroad. Alliancestudies connect coalition participation problems with the reliabilityof allied countries (Leeds, 2003; Gartzke and Gleditsch, 2004).These studies seem to provide a fairly good picture on the question;however, they are not free of problems. In particular, theystudy only coalitions for interstate war and militarized disputesbut ignore coalitions for other purposes. Coalitions can beformed for military operations other than war (Kober, 2002).There are coalitions for humanitarian intervention, peacekeeping,and even for the evacuation of noncombatants. This article showshow difference in operation-types and collective legitimacyaffect the decision of a state to participate in US-led coalitions.A coalition with United Nations' authorization may appear tobe a legitimate international ‘police’ act and attractmore partner states. A coalition for intervention into domesticaffairs may be less attractive to possible participants becauseof the violation of the noninterference norm of internationallaw. Statistical analysis on United States coalition partnersfrom 1950 to 1999 suggests that how and for what purposes coalitionsare formed cannot be overlooked. Coalition participation isnot fully explained by the existing perspectives found in war/dispute-diffusionliterature and alliance studies, and there is a need to invoke‘the compulsion of the coalition's missions and legitimacy’.

Sudden death due to undiagnosed intracranial hemangiopericytoma

A previously healthy 9-year-old Japanese boy with a 4-day history of vomiting and headache died suddenly and unexpectedly. An external examination revealed no abnormalities other than foam around the mouth and nose. An internal examination revealed severe pulmonary edema and hemorrhagic hemangiopericytoma arising from the choroid plexus of the right lateral ventricle. The cause of death was thought to be neurogenic pulmonary edema caused by the rapid growth of a hemangiopericytoma, with intratumoral hemorrhage.     

Estimating age of humans based on telomere shortening

To estimate age using DNA based on telomere shortening, we determined the terminal restriction fragment (TRF) length, as telomere length, using Southern blot analysis of peripheral human blood and blood stains. All blood stains had been stored at room temperature for 5 months. The average TRF length clearly showed a tendency to shortening with aging. The formula for age estimation was based on a correlation between average TRF length and age of the subjects. The estimated age calculated from TRF length widely depends on environmental and genetic factors. However, as long as the DNA is well preserved, use of our method is feasible regardless of age of the subject and can give a rough estimation of age of subjects in forensic samples that carry no morphological information.
