美国房地产的兴衰故事

尽管人们的预测每每以失败告终，但我们可以换个角度来看待此事。或许这并不表示人类失去了预言能力，而只是表明目前如此之高的房价其实是一种异常与扭曲，早晚一天它会出现回调     

美利坚帝国

假如你是现代的罗马皇帝,在世界各国和国际市场中,你领导着一个最强大的国家。在这个国际的政治经济环境中,你不必投入太多,但收获甚丰,使你的国家地位无比显赫,使你的子民所消费的物质远远超出他们所生产的物质,但这能长此

LAUDING CHINA'S RESOLUTION

Outbreak in UK makes people realize the necessity for drastic steps Apart from deaths and the distress caused to those most directly affected,another product of the novel coronavirus epidemic has been the increase in abusive behavior outside China toward people who are-or perceived to be-of Chinese ethnicity.

Capillary ion electrophoresis of endogenous anions and anionic adulterants in human urine

Normal human urine contains many anions and cations. Ionic concentrations in urine have classically been determined by spectrophotometry of color reactions, flame emission spectrophotometry, atomic absorption spectrophotometry, high performance liquid chromatography, or potentiometry with ion-specific electrodes. Capillary ion electrophoresis (CIE) is a form of capillary electrophoresis which uses the differential electrophoretic mobility of ions to perform a separation of an ionic mixture. Various salts can be added to urine specimens to abnormally elevate ionic concentrations and interfere with either immunoassay urine drug screening procedures or gas chromatographic/mass spectrometric confirmation techniques. Application of CIE for the direct detection of endogenous anions and anionic adulterants in human urine specimens was the purpose of this investigation. CIE was performed using a Waters Quanta 4000 Capillary Electrophoresis System with either direct or indirect ultraviolet absorption detection at 254 nm. CIE of 30 random normal urine specimens and 21 urine specimens suspected of adulteration was performed. Duplicate aliquots were assayed by CIE and by colorimetric technique for nitrite. Sixteen specimens had elevated concentrations of nitrite and/or nitrate. The correlation coefficient between nitrite CIE and colorimetric results was 0.9895. Three specimens had detectable concentrations of chromate and were suspected of being adulterated with "Urine Luck," an adulterant found to contain chromate. Two specimens suspected of being adulterated with bleach were found to only contain chloride, sulfate, and phosphate. CIE is applicable to forensic analysis of urine anion concentrations. CIE can easily quantitate numerous endogenous anions and offers a method to detect and/or confirm anion adulteration of urine specimens.     

民粹动员:一种研究民粹主义的新方法

人们对民粹主义的概念历来众说纷纭,但是将民粹主义视为一种政治动员手段可以有效避免在概念上的模糊和分歧。这种政治动员手段就是民粹动员,它通过持久的政治运动和民粹主义的话语体系发动大众动员,将团结一致的"人民"置于某种对抗反大众"精英"的纵向关系中。通过民粹动员的方法研究20世纪中期拉美的民粹主义,能够更好地阐明这一时代的政治形势,同时也可以为今后的研究指明一个新方向。     

当民粹主义政客代替技术官僚

如今，与科学证据作对成为一种政治手段：左翼和右翼政客通过这样做来营造反精英的民粹主义形象。但这—方法有害于公共健康和地球，一些科学家已经开始担心有可能产生新的“科学封建主义黑暗时代”。
