消费主义会过早耗损中国的发展资本吗?

在中国人均GDP刚过1000美元,贫富差距扩大的情况下,中国正在提前迈入奢侈品消费的大国.虽然消费结构向发展型、享受型升级,消费水平的提高是文明进步的表现,然而,消费主义的盛行会在国家还未壮大时就过早消耗掉继续发展的资本.所以,必须对流行于中国的消费主义保持应有的警惕,并从国家层面节制过度消费.     

The Determinants of Palestinians' Attitudes Toward Peace with Israel

This study explains the variations in the Palestinians' support of the peace process with Israel. It uses multivariate Logit analysis, employing a large public opinion poll conducted in January 2000. It tests seven hypotheses, drawn from various perspectives, on the conditions of Palestinian support of or opposition to the peace process.
The study supports several of our hypotheses including the positive association between the Palestinians' perceptions of democracy and the support of peace and Palestinian women's support of the peace process. These results are important because they reconfirm the findings of the vast international relations literature, which established a strong linkage between democracy and peace and that women are more peace-oriented than men.
The study further suggests that the Palestinians associate their support of the peace process positively with their trust of domestic political institutions, a sound nation-building process, and governmental public accountability, and negatively with the perception of governmental corruption. It also reveals that the Palestinians' positive evaluation of their domestic institutions and Israel's commitment to a just and fair settlement to the conflict are more important determinants of the support of the peace process than efforts to improve their economic conditions and that the economic conditions have, at best, a small impact upon the support of or the opposition to peace. Lastly, the study points to the presence of a positive relationship between support of the peace process and each of political institutionalization, party identification, and the second level of leaders. This finding points to an emerging trend among Palestinians toward political maturation and stabilization of their domestic politics.     

A case of sudden infant death due to massive hemorrhage in primitive neuroectodermal tumor.

A case of the sudden death of a 14-month-old girl due to massive hemorrhage in a primitive neuroectodermal tumor (PNET) is presented along with a review of the relevant literature. PNET is a rare, malignant brain neoplasm occurring predominantly in children.     

Polymerase chain reaction (PCR) amplification and human leukocyte antigen (HLA)-DQ alpha oligonucleotide typing on biological evidence samples: casework experience.

The polymerase chain reaction (PCR) method of specific gene amplification was used in casework to synthesize millions of copies of the polymorphic second exon of the human leukocyte antigen (HLA)-DQ alpha (or DQA1) locus from a variety of evidence samples. The HLA-DQ alpha allelic variants in the amplified deoxyribonucleic acid (DNA) were determined in a rapid non-radioactive test by hybridization to sequence-specific oligonucleotide probes in both the dot-blot and reverse dot-blot formats. This genetic typing system has been subjected to blind proficiency testing; the performance of this test in the analysis of experimentally mixed samples was also evaluated. As of August 1990, over 250 cases have been tested and more than 2000 individual evidence (bloodstains, semen stains, individual hairs, bone fragments, and tissue sections) and reference samples have been analyzed. The first 198 of these cases are summarized in this paper; in 65% of the cases with conclusive results a suspect was included, and in 35%, all suspects were excluded. Individual cases as well as some of the general issues relating to forensic science analysis and this genetic typing system are discussed. The high rate of exclusion reported here combined with the ability of PCR to type old evidence samples suggests the relevance of this genetic test for postconviction review; two cases in which the convicted suspect was excluded are discussed.     

Measuring carbon monoxide content in muscles

A method ist described to determine the CO-content in the tissue of muscles. The prepared tissue is pulverized in a swinging mill at the temperature of liquid nitrogen. Parts of the powder are weighed into headspace vessels. Carbon monoxide ist ejected by a formerly described method and measured gaschromatographically. The Fe-content is determined after an acid disintegration by AAS. Acute intoxications lead to higher CO-contents in heart than in periphere muscles. Chronic exposure to carbon monoxide does not produce these differences.     

Sudden death in angiodysplasia of the gastroesophageal junction.

A 22-year-old Korean soldier, who had received blows to the neck and epigastrium from an officer 10 h earlier, suddenly died after massive hematemesis. He had been in relatively good health except for episodes of blood-tinged vomiting approximately 5 and 7 months prior to this event. Postmortem examination revealed angiodysplasia involving the gastroesophageal junction, and the stomach was distended with blood. No abnormal findings were present around the whole viscera, and the duodenum was free of blood. The pathologic significance of upper gastrointestinal angiodysplasia as a potential source of bleeding and a chronologic correlation between the trauma and bleeding are discussed.
