Poppy seed ingestion as a contributing factor to opiate-positive urinalysis results: the Pacific perspective.

The possible contribution of poppy seed foods to positive opiate urinalysis results, especially from foods available in the Pacific Rim area, has recently become an issue for the U.S. Army Forensic Toxicology Drug Testing Laboratory in Hawaii. To assess the likelihood of this possible contribution, seven different poppy seed food products were consumed by male and female volunteers, and urine specimens were collected at time increments up to either 24 or 72 h. Specimens were evaluated for opiates using Roche Abuscreen radioimmunoassay (RIA), and all RIA positive specimens were analyzed for morphine and codeine using gas chromatography/mass spectrometry (GC-MS). Poppy seed cake, bagels, muffins, and rolls did not contain sufficient quantities of poppy seeds to give rise to opiate positive specimens by U.S. Department of Defense (DOD) GC-MS cutoff levels (morphine = 4000 ng/mL, codeine = 2000 ng/mL), although a number of specimens were positive by National Institute on Drug Abuse (NIDA) cutoff levels (morphine and codeine = 300 ng/mL). However, ingestion of poppy seed streusel or Danish pastry led to confirmed morphine and codeine positive specimens, irrespective of the use of DOD or NIDA confirmation cutoff values. In addition, significant amounts of codeine were observed in a number of these specimens. These findings argue against the unqualified application of previously published quantitative guidelines for eliminating poppy seed ingestion as a possible cause for a positive opiate urinalysis result.

EU-China relations: balancing political challenges with economic opportunities

During 2005, the European Union and China marked 30 years of diplomatic relations with much fanfare. Celebrations surrounding the anniversary however belied the fact that throughout most of this period the European Union and China remained largely aloof from one another. The strengthening of EU foreign policy over time, as well as the economic reforms and new outward orientation exhibited by China have changed the dynamics of the relationship. Both sides are increasingly recognizing the potential mutual benefits that can be accrued from a closer relationship. This paper assesses EU-China relations from both economic and political perspectives. In terms of economics, it is clear that the EU must build stronger relations with China if it is to accrue the benefits of access to an expanding market with over one billion people. To do so successfully however, the EU will have to reconcile the economic and political components of its foreign policy. The EU continues to challenge the Chinese government to reform its practices on a number of issues including human rights, democratic reform, and Tibet, all of which remain bones of contention. How the EU achieves the balance between political constraints and economic opportunities is the primary focus of this paper.

PREDICTING WHO REOFFENDS: THE NEGLECTED ROLE OF NEIGHBORHOOD CONTEXT IN RECIDIVISM STUDIES*

Prior studies of recidivism have focused almost exclusively on individual‐level characteristics of offenders and their offenses to explore the correlates of reoffending. Notably absent from these studies are measures reflecting the neighborhood contexts in which individuals live. The current research addresses this shortcoming. Using data on a sample of ex‐offenders in Multnomah County, Oregon (Portland and surrounding area) in conjunction with 2000 census data, we answer two questions. First, which individual‐level factors influence rates of recidivism? Second, to what extent does neighborhood socioeconomic status account for variation in the reoffending behavior of ex‐prisoners that is not explained by their individual‐level characteristics? We find that those who return to disadvantaged neighborhoods recidivate at a greater rate while those who return to resource rich or affluent communities recidivate at a lesser rate, controlling for individual‐level factors.     

Ethnicity, gender, and the Level of Service Inventory-Revised

Offender assessment and classification is becoming an increasingly important part of correctional supervision and intervention. Over the last several decades, several different methods and “generations” of offender classification have emerged. Of most value appear to be third-generation, actuarial, dynamic risk/need assessments. With any new correctional strategy, however, there is a need to investigate the use of these risk/need assessments on offender subgroups in order to inform issues, such as reliability and prevalence of criminogenic risk factors. The present study utilized data that were gathered using the Level of Service Inventory-Revised (LSI-R). Results and comparisons of these assessments were investigated and presented for Native American and non-Native American offenders as well as male and female offenders. Discussion of the results, implications, and recommendations for further research are presented.     

友谊和相互理解的盛会——谈俄罗斯"中国年"

我的老朋友和同行冯绍雷教授请我谈一谈我对俄罗斯"中国年"的想法,对此我欣然应允。3月26日,俄罗斯"中国年"开幕式在克里姆林宫隆重举行。两国领导人——胡锦涛主席和普京总统在讲话中强调了中俄两国互办"国家年"的意义,强调了两国人民命运和两国主要发展目标上的历史共性。实际上,正是两国领导人自己提出了举办这种大规模活动的倡议。中国艺术家们在克里姆林宫剧院的大型演出,成为中国音乐、舞蹈和杂技艺术所取得的突出成就的真实展示。演员们的表演受到了     

从红色威胁到激进民众主义——拉丁美洲对美国的非安全因素

*2004年11月,美国总统乔治.W.布什在阿根廷参加第4届美洲国家首脑会议期间,受到了来自民众的强烈抗议。这是自1958年时任美国副总统的理查德.M.尼克松在委内瑞拉被愤怒的民众投掷石块以来,美国政府高级官员在拉丁美洲受到的最差的待遇了。在委内瑞拉总统乌戈.查韦斯和玻利维亚总统候选人埃沃.莫拉莱斯的鼓舞和煽动下,数万名民众举行集会,谴责美帝国主义和已遭搁浅的美洲自由贸易区计划。布什会受到强烈抗议,事先并非毫无征兆。在他出访前夕进行的民意调查显示,53%的南美洲人和87%的拉美“意见领袖”(Opinion Leaders)对美国总统表示反感,…
