The growing literature about mixed electoral systems has addressed their effect on party systems, voting behavior, campaign strategies, legislative roll-call voting, and other issues in a handful of countries. But, the effect of mixed systems has not been fully evaluated cross-nationally or longitudinally. Using data from the World Bank’s Database of Political Institutions, we address this gap in the literature by investigating two related questions. First, do mixed electoral rules produce different election outcomes than other election rules? Second, are these results attenuated by the definitions of mixed systems that scholars employ? We find that mixed systems generate outcomes that are distinct from other electoral systems and that these findings are generally robust across different definitions.  相似文献

A simple determination method of amphetamine (AP) and methamphetamine (MA) in human blood was developed using on-column derivatization and gas chromatography-mass spectrometry (GC-MS). AP and MA were adsorbed on the surface of Extrelut and then derivatized the N-propoxycarbonyl derivatives using propylchloroformate. Pentadeuterated MA was used as an internal standards. The recoveries of AP and MA from the spiked blood were 89.7 and 90.3%, respectively. The calibration curves showed linearity in the range of 12.5-2000 ng/g for AP and MA in blood. The coefficients of variation of intraday and interday were 0.42-4.58%. Furthermore, this proposed method was applied to some medico-legal cases of MA intoxication. MA and its metabolite AP were detected in the blood samples, and the correlation of the blood level of amphetamines and the behaviors of the victims was in good agreement with the criteria proposed by Nagata [Jpn. J. Legal Med. 37 (1983) 513].  相似文献

China has realised excellent rapid economic growth for the last 27 years following Taiwan and Korea, which maintained rapid growth for nearly 40 years. This has mainly been achieved by extraordinary high fixed assets investment, especially investment in real assets, as well as export expansion. However, new structural contradictions have emerged. They include workers laid off through downsizing of state-owned corporations, non-privileged farmers who have migrated into cities, and landless peasants. China is now at a turning point for the central government to drastically transform existing fiscal institutions in order to redistribute the dividends of high economic growth to the poor and poor areas, against the trinity of local bureaucracy, real estate developers, and state-owned banks.  相似文献

After the prolonged stagnation that followed the post-Bubble economic collapse at the end of the 1980s, from 2002 onwards the Japanese economy exhibited its longest period of economic expansion (albeit gradual) since World War Two. As this expansion came to an end and the economy was on the verge of the downward curve of the economic cycle, it was confronted with the current financial and economic crises, which originated in the USA. Nevertheless, Japanese financial institutions had invested little in sub-prime-related financial products, and with the lessons learned from the issue of bad loans in the 1990s, Japan's financial system enjoyed greater stability than that of any other major nation. However, in the period from the end of 2008 to early 2009, Japan experienced the sharpest economic decline of any major nation.

Yet, with the worst period having ended in the spring of 2009, the International Monetary Fund (IMF) has predicted in its October 2009 forecasts that Japan will experience real economic growth of 1.7% in 2010—a higher rate than the USA (with 1.5%) or the Euro Zone (with 0.3%). Despite forecasts of a protraction of excessive US imports as a direct result of excessive US consumption, Japan is being forced to reduce its degree of reliance on exports to the USA and to make major adjustments to its export structure—both in terms of the regions to which it exports and the products that it exports. Japan also faces the task of setting itself on the path to economic growth, using the twin drivers of foreign demand and domestic demand, and this will necessitate the cultivation of domestic demand. Now, the long-term strategy for Japan is to promote the expansion of regional demand in Asia, to couple this regional demand with domestic demand, and to latch on to Asia's economic dynamism.  相似文献

A case of fatal poisoning due to the combined effect of alcohol and gasoline following an automobile accident is described. Toxicological analyses by means of gas chromatography and gas chromatography-mass spectrometry permitted the identification and quantitation of alcohol and several hydrocarbons in the heart blood and in the gas in the lung. Great variation was found in the estimates of blood gasoline concentration, depending on which of six constituents of gasoline was chosen for quantitation. The cause of this variation is discussed, together with the possible mechanisms leading to death.  相似文献

A 23-year-old male attempted suicide by ingesting approximately 50 ml of 5% fenitrothion emulsion, and vomited soon afterwards. He was admitted to a hospital about 3 h after ingestion. He recovered and was discharged from hospital 3 days after admission. The serum cholinesterase activity (normal range: 175-440 I.U.) was only 29 at 3 h, 32 at 1 day, 59 at 2 days and 75 at 3 days after ingestion. Fenitrothion and its metabolites in the body fluids were extracted by an Extrelut column extraction method, detected by a gas chromatograph equipped with either a hydrogen flame ionization detector or a flame photometric detector, and confirmed by a gas chromatograph-mass spectrometer. Fenitrothion concentration in the blood was 169.5 ng/g at 3 h after ingestion. The half life of blood fenitrothion concentration was found to be about 4.5 h. Fenitrothion metabolites, 3-methyl-4-nitrophenol, aminofenitrothion, aminofenitroxon, acetylaminofenitroxon and S-methylfenitrothion, were detected in the urine samples. All of them except S-methylfenitrothion were detected in the urine samples collected up to 62 h after ingestion. It would appear therefore that fenitrothion poisoning can be determined by detection and analysis of the metabolites in urine even if fenitrothion has not been detected in the blood.  相似文献

When a body is discovered in water, it is difficult to conclude whether the cause of death was drowning, even today. Although diatom testing by the digestive method is classical, we hypothesized that aquatic bacteria, as well as diatoms, might be detected in drowned bodies, and conducted temperature gradient gel electrophoresis (TGGE)‐targeting 16S rDNA. DNA was extracted from the site water, and from heart blood and liver samples from 27 bodies concluded as drowning deaths by autopsy and subjected to TGGE after amplification of 16S rDNA by polymerase chain reaction. We observed whether the feature point of each 16S rDNA from the site water and blood or liver samples matched. Considerably higher correspondence was observed in drowned bodies, and the rate was higher than that achieved with the digestive method. Moreover, TGGE is safer than the digestive method. Our study suggests that this method can aid diagnosis of drowning.  相似文献

A simple and rapid method for analysis of free and conjugated cresols in biological fluids was developed. Prior to and following freeing of the conjugated cresols by acid hydrolysis in a sealed ampoule, free cresols were extracted by Extrelut column extraction, determined by gas chromatography, and confirmed by gas chromatography-mass spectrometry. In a non-fatal case of cresol intoxication a 46-year-old male had ingested about 100 ml of a saponated cresol soap solution. The concentrations of xylenol (2,4- and/or 2,5-dimethylphenol) and p- and m-cresol in the serum sample collected on admission were 15.8 micrograms/g, 43.3 micrograms/g and 73.8 micrograms/g, respectively. The total cresol concentration of 117 micrograms/g in the serum is within the range of fatal concentrations, and it is suspected therefore that the patient's recovery was due to adequate therapy alone.  相似文献

Although Sino‐Japanese relations seem much improved in recent years, Tomoyuki Kojima, professor of political science at Keio University, still sees numerous problems that Japan must come to terms with before the two countries can develop a truly close relationship. Points of friction include Japan's past aggression in China, Chinese nuclear testing, regional security issues, and China's criticism of Japan. This paper was presented at the conference, “China and Japan in the Asia‐Pacific region since the Pacific War and Prospects for the Future,” held in Beijing on Nov. 12–13, 1995, by the China Institute of Contemporary International Relations and the Australian National University.  相似文献
