Adjudication of patent validity is sent home

The Court of Justice restrictively interprets the Brussels Convention,frustrating the development of transnational adjudication ofpatent infringement claims by precluding a court from consideringthe validity of a foreign patent even where the decision onlyhas effect between the parties.

中美警察差异点滴——以一个美国教授的视角

2010年1月5日至1月10日,在山姆·休斯敦州立大学刑事司法学院教授的努力下,浙江警察学院第一批赴美访学区队17名师生在美国德克萨斯州艾尔文和解放城两个城市的警察局进行了为期5天的警局见习。在此期间,同学们与美国警察一起巡逻,一起查缉毒品犯罪,一起走入美国人的社区。对美国警察的日常工作有了最直接而感性的认识,受益匪浅。菲利普·劳恩斯教授在《德州巡警》专栏上撰文记录了这段中美警察深度交流的故事,特译该文在本专栏刊登。     

“Asian Really Don’t Do This”: On-Scene Offense Characteristics of Asian American School Shooters, 91–07

Between 1966 and 2007, there were 44 mass murder incidents across schools and universities in the United States. Three of those incidents involved Asian school shooters. By using newspapers and government reports about the incidents, this paper examines the patterns of weapon acquisition, weapon deployment, and tactical deployment strategies of the three Asian school shooters. The role of the mass media as sources of identification fantasies, legitimacy, and ideational structures for the planned attacks are considered. The meaning of being an Asian school shooter in the United States is discussed.     

Lifestyle illicit drug seizures: A routine ESI-LC-MS method for the identification of sildenafil and vardenafil

For street samples suspected of containing the phosphodiesterase-5 inhibitors sildenafil (Viagra(?)) and/or vardenafil (Levitra(?)), including powders or adulterated herbal supplements, a chemical analysis is needed to provide confirmatory identification of these illegally procured substances. Sildenafil and vardenafil are structurally similar and it is difficult to differentiate between them, as previous mass spectrometric studies have shown the two drugs to produce similar fragmentation patterns. The use of tandem mass spectrometry can produce confirmatory data, but the technique requires a high level of technical expertise. We have developed an electrospray ionization-liquid chromatography-mass spectrometry (ESI-LC-MS) method that allows differentiation between these two structurally similar molecules via in-source fragmentation in combination with an ion trap mass spectrometer. A very stable gas phase ion is formed during in-source fragmentation of vardenafil; the combination of the stability of this ion and the longer residence time for the ion in the ion trap results in a very strong signal. This feature results in a method that can provide clear differentiation between sildenafil and vardenafil while at the same time requiring less expertise from the routine analyst to confirm the presence or absence of the two compounds.
