Immunocytochemical studies were performed on tracheal wall samples embedded in paraffin; the samples were taken at 23 autopsies. In all cases, the red cells had been typed in postmortem serological studies as being Le(a-b-). Blood-group antigens were demonstrated by the indirect immunoperoxidase technique, using monoclonal Anti-A, Anti-B, Anti-Lea and Anti-Leb; H was detected by UEA 1. The secretor characteristics could clearly be diagnosed from the ABH staining pattern of the mucous glands. In 11 cases, the lewis antigen labeling patterns were identical to the group of Lewis-positive individuals. It seems probable, from the statistical point of view, that these 11 individuals were, in fact, Lewis-positive and that the negative serology resulted from deterioration of the cadaver blood samples. The immunocytochemistry was quite different in the remaining 12 cases: (a) secretors (n = 9) were completely negative for Lea, Leb was equally negative in one case, but in the remainder it was detectable within mucous epithelia in minimal amounts and in an atypical granular distribution; (b) nonsecretors (n = 3) reversely exhibited complete negativity for Leb but a minimal staining for Lea. These findings are in harmony with the well established Lewis serology typing of secretions in Lewis negative individuals. Thus, a minimal Lewis antigen biosynthesis and secretion seem to occur in the absence of the Le gene: A alpha-4-L-fucosyltransferase of low activity might be the product of the allele le. 相似文献

ABSTRACTThe paper deals with the issue of overpricing of public procurement in low-performing EU countries. It examines a uniquely large sample of public procurement in 11 Central and Eastern European countries. Hierarchical regression is used to analyze the factors that influence public contract. Our results indicate that institutional factors have a greater impact on overpricing than individual decisions by the contracting authority. Our analysis for low-performing EU countries provides interesting results and also draws attention to behavior that is not typical of the better established and more advanced EU countries. Our results are particularly important for public policy in each country, as they show the direction of regulatory action in the field of public procurement. The results introduce a debate on the appropriateness of “one size fits all” regulations within the EU. 相似文献

Despite efforts to increase gender diversity and equality worldwide, women are still underrepresented in leadership positions in public bureaucracies. This article speaks to the debate on how organizational context, more specifically organizational decline, may influence gender representation in such leadership positions. Based on role congruity theory and glass cliff theory this article empirically examines whether and how excessive workforce reductions are associated with changes in the representation of women in leadership positions in Dutch civil service organizations. Panel analyses on administrative data show that women's representation in leadership positions varies over time, but is not significantly affected by excessive workforce reductions. Overall, the analyses do not provide evidence for a glass cliff for women in Dutch civil service organizations. Implications for theory and future research are discussed. 相似文献

This essay offers a critical examination of use of the term “long civil rights movement” as a framework for understanding the legal history of the battle against racial inequality in twentieth‐century America. Proponents of the long movement argue that expanding the chronological boundaries of the movement beyond the 1950s and 1960s allows scholars to better capture the diverse social mobilization efforts and ideas that fueled the black freedom struggle. While not questioning the long framework's usefulness for studying the social movement dynamics of racial justice activism, I suggest that the long framework is of more limited value for those who seek to understand the development of civil rights, as a legal claim, particularly in the first half of the twentieth century. The tendency of long movement scholars to treat civil rights as a pliable category into which they can put any and all racial justice claims is in tension with historical understandings of the term. Susan Carle's Defining the Struggle: National Organizing for Racial Justice, 1880–1915 suggests an alternative approach. Her detailed and nuanced account of a period in American history when racial justice activists understood civil rights as a relatively narrow subset of legal remedies within a much broader struggle for racial equality indicates the need for an alternate history of civil rights—one that places the evolving, contested, and historically particularized concept of civil rights at the center of inquiry. 相似文献

ABSTRACTTen years after the coming into force of the EU–South Africa Strategic Partnership, this article takes stock of this partnership. Our aim, within this special issue, is to assess the EU’s perspective on its strategic partnership with South Africa, and in particular to look at economic and development cooperation within the partnership and to what extent European expectations of closer engagement have been met. Our analysis shows that economic interests have remained central to bilateral relations and the strategic partnership, even if some potential for economic engagement has remained unexploited. At the same time, the relationship has been quite tense in recent years, as bilateral ‘affection’ at the political level has waned. The implications for the partnership are weighed. 相似文献
