Concordant Intestinal Atresia in Two Pairs of Monozygotic Twins
2011
Intestinal atresia in both twins from the same pregnancy is very rare. Only seven pairs of twins have been described. The authors report on two cases of monozygotic twins with different types of intestinal atresia and clinical evolution. Both pairs of observed twins turned out to be concordant for the presence of intestinal malformations and for the absence of other linked malformations; nevertheless, the atresic lesions were anatomically discordant in each pair of monozygotic twins. Therefore, the diagnostic and therapeutic procedures have shown some differences in phenotypic expression between the twins of both pairs. Possible etiologic factors and pathogenetic pathways are discussed, and…
AN ASSOCIATION INDEX FOR RECTANGULAR CONTINGENCY TABLES WITH ORDERED/UNORDERED VARIABLES
2016
In a previous work, Mineo and Ruggieri (2005) introduce a new index to measure the association in square contingency tables; in this paper such an index is extended to rectangular tables, preserving the same properties. The considered domain includes all the contingency tables with equal n (the total number of observations), since the tables of maximum dependence, useful for computing the denominator of the proposed index, belong to it. The main findings, which prove the effectiveness of the proposed measure, are presented. In particular, the new measure assumes values in the range [-1,+1], taking value zero in tables with distributive independence and positive/negative values if associatio…
Managing Relations: a study of positioning strategies in British international discourse
2008
This work deals with corpus-assisted research into speaker ideological positioning in the language of diplomacy. It concentrates on the resources used by the foreign minister Margaret Beckett to construe the speaker “orientation” (Lemke 1992) through the analysis of the main participant in the discourse that is international community and the subject matter being debated namely terrorism. The findings have shown assertiveness and determination from the speaker by the use of contractive mechanisms. The image of the international community is based on cooperation and unity just like a family and it is appraised mainly through judgements of tenacity. These are the resources required to fight t…
