Seven ethyl homologues of known tropane esters have recently been detected as impurities in the gas chromatographic signature profiles of authentic Peruvian illicit cocaine base and hydrochloride exhibits. Peruvian cocaine base processors are now known to use ethanol for the purification of crude cocaine base. This process is referred to as the "base lavada" or "washed base" process and is a recent substitute method for the potassium permanganate oxidation purification methodology. Seven ethyl ester homologues were formed in illicit cocaine from the transesterification of known tropane methyl esters or possibly ethyl esterification of their respective tropane C-2 carboxylic acids in the presence of ethanol. Exhibits containing these compounds were subjected to gas chromatographic-mass spectrometric analyses to determine their identity and were subsequently synthesized to verify their structures. Quantitative determinations were obtained from ion-pair chromatography isolation followed by gas chromatography with flame ionization detection. Specifically, hexanoylecgonine ethyl ester, cocaethylene, cis-cinnamoylecgonine ethyl ester, trans-cinnamoylecgonine ethyl ester, 3',4',5'-trimethoxybenzoylecgonine ethyl ester, cis-3',4',5'-trimethoxycinnamoylecgonine ethyl ester, and trans-3',4',5'-trimethoxycinnamoylecgonine ethyl ester were detected and characterized. When present, these compounds were detected at levels ranging from 8.6 x 10(-4) to 9.3 x 10(-1)% relative to cocaine. 相似文献

This article examines why some state legislators run for Congress and others do not. Our main argument is that there are differences in the expected value of a state legislative seat and the expected benefits of being a member of Congress. One key component of this value is how closely the candidate fits with her party. We find that the probability of seeking congressional office increases among state legislators who are distant from the state party and proximate to the congressional party and decreases among those who are distant from the congressional party and proximate to the state party. 相似文献

This paper uses the official juvenile offenses among delinquent girls in the 1958 Philadelphia Birth Cohort to investigate the two overarching questions. This research investigates the nature of delinquency conduct, offense-by-offense, and its relationship to adult crime status. Although it is convenient to think of an offender’s delinquency career as a whole, such a career actually consists of one or more specific offenses, and offense conduct can be worth studying in its own right. Thus, it is necessary to determine whether the timing, type, severity, court disposition, and so on, of these juvenile offenses can be used to predict adult career pathways. An extensive review of the literature revealed that investigations of early offense conduct and its connection to adult crime are exceedingly scarce. This study indicates as follows. First, the way a delinquent begins her criminal career is predictive of the adult trajectory that will be followed. Second, we also found that aspects of the first few offenses doe influence whether delinquent girls do continue committing crimes as adult. The strongest predictor of adult crime status was juvenile court dispositions. 相似文献

State‐funded scholarship programs are transforming the way citizens and policymakers think about higher education. Advocates see these programs as a remedy to problems facing the state workforce such as “brain drain” and “unequal opportunity” for a sound education. Opponents see low retention rates and the number of already‐privileged students receiving benefits as signs that these programs are not reaching their maximum potential. This article traces the development of state‐funded college scholarships from earlier need‐based programs to current merit‐based programs and outlines current debates on policy effectiveness. Currently, 14 states have a state‐funded scholarship program. Differences between programs revolve around the political and economic circumstances of each state. 相似文献

Comparison in legal education matters. In its mission statement, the International Society of Public Law suggests that, “a full explication and understanding of today’s ‘constitutional’ [law] cannot take place in isolation from other branches of public law or in a context that is exclusively national”. Not only is comparative content of itself enlightening, but this paper argues comparison as a teaching method has at least four virtues. First, teaching in a comparative paradigm better prepares graduates for an interconnected and global legal marketplace. Second, it helps illuminate curriculum content. Third, it makes for good citizenry. And, fourth, it enhances the research/teaching nexus. In so doing, this paper explores the use of comparative law as a teaching methodology in core public law subjects rather than by way of additional curriculum content. As with all things, however, where there are virtues, there are also vices. In this context, such vices include questions of relevance and threats to space, time and coherence in legal education. To that end, the disadvantages of comparative approaches in teaching public law are also considered. 相似文献

An increase in adolescent distress and mental health symptoms has been clearly documented since the COVID-19 pandemic, as has increased exposure to adverse childhood experiences. Layer on top of these stressors being a youth of divorcing or separating high conflict families, and adolescent symptomatology can suddenly become a flashpoint for parental attention, division and conflict. Approaching cases using an ecological and family systems framework is necessary for accurate conceptualization and assessment of best interests in the context of child custody evaluations. Doing so ensures that adolescent mental health does not become a red herring in high conflict cases, leading to undue focus on the adolescent's mental health without considering other salient factors in the case, such as the broader parent conflict. Programs offered at the Center of Excellence for Children, Families & the Law at William James College designed to improve the lives of youth by addressing parental conflict are described. 相似文献
