DNA profiling using STRs on the 310 and 3100 Genetic Analyzers routinely generates electropherograms that are analyzed with the GeneScan software available from the instrument's manufacturer, Applied Biosystems. Users have been able to choose from three different smoothing options that have been known to result in significant differences in the peak heights that are reported. Improvements in the underlying algorithm of the most recent version of the software also result in significant and somewhat predictable differences in peak height values. Laboratories that have performed validation studies using older versions of GeneScan should either reanalyze the data generated in those validation studies with the newest version of the software or otherwise take into consideration the systematically higher peak height values obtained as they begin following the recommendation of the manufacturer and use the new algorithm. 相似文献

Selection bias is an important but often neglected problem incomparative research. While comparative case studies pay someattention to this problem, this is less the case in broadercross-national studies, where this problem may appear throughthe way the data used are generated. The article discusses threeexamples: studies of the success of newly formed political parties,research on protest events, and recent work on ethnic conflict.In all cases the data at hand are likely to be afflicted byselection bias. Failing to take into consideration this problemleads to serious biases in the estimation of simple relationships.Empirical examples illustrate a possible solution (a variationof a Tobit model) to the problems in these cases. The articlealso discusses results of Monte Carlo simulations, illustratingunder what conditions the proposed estimation procedures leadto improved results. 相似文献

Decisions of the Court of Justice have challenged traditional notions of sexual discrimination. In P v S and Cornwall County Council, the Court held that discrimination against transsexuals was contrary to the 1976 Equal Treatment Directive. However, in Grant v South‐West Trains, the Court rejected arguments that Article 119 on equal pay prohibited discrimination on the basis of sexual orientation. This article contrasts the two decisions, and in particular focuses on the inconsistencies in the Court's definition of what constitutes sexual discrimination. The article further considers the underlying factors which may have influenced the Court's judgment, including the moral dimension and the political context of the two decisions. Finally, there is a discussion of the merits of equality litigation strategies, in particular at the Court of Justice. 相似文献
