On a question of Bhatia and Kittaneh
No full textAbstractWe settle in the affirmative a question of Bhatia and Kittaneh. For P and Q positive semidefinite n×n matrices, the inequality σr(PQ)⩽12λr(P+Q) holds for r=1,2,…,n
Unravelling of the paroxysmal dyskinesias
No full textParoxysmal dyskinesias (PxD) refer to a rare group of clinically and genetically heterogeneous disorders presenting with recurrent attacks of abnormal movements, typically dystonia, chorea or a combination thereof, without loss of consciousness. Classically, PxD have been categorised according to their triggers and duration of the attacks, but increasing evidence suggests that there is a certain degree of clinical and genetic overlap and challenges the concept that one phenotype is attributable to one single aetiology. Here we review the increasing spectrum of genetic conditions, as well as of other non-genetic disorders, that might present with PxD, provide criteria for case definition and propose a diagnostic workup to reach a definitive diagnosis, on which treatment is heavily dependent
Symmetries and variation of spectra
No full textBhatia R, Elsner L. Symmetries and variation of spectra. Canadian journal of mathematics. 1992;44(6):1155-1166.An interesting class of matrices is shown to have the property that the spectrum of each of its elements is invariant under multiplication by p-th roots of unity. For this class and tor a class of Hamiltonian matrices improved spectral variation bounds are obtained

On joint eigenvalues of commuting matrices
No full textBhatia R, Elsner L. On joint eigenvalues of commuting matrices. Canadian Mathematical Bulletin. 1996;39(2):164-168.A spectral radius formula for commuting tuples of operators has been proved in recent years. Pie obtain an analog for all the joint eigenvalues of a commuting tuple of matrices. For a single matrix this reduces to an old result of Yamamoto
Polyphony and dialogism in legal discourse: focus on syntactic negation
No full textThis study draws on the notion of polyphony to discuss some inherent properties of discursive practices in the legal domain.
In particular, it focuses on judgments, and analyses them as highly stratified argumentative texts in which judges construct their opinions and decisions making references to other authori-tative texts (precedents, statutes, etc.), and at the same time give account of the stances of the various parties involved (prosecu-tor, defence counsel, defendant, witnesses, experts, police inves-tigators, etc.). In this way they also respond to all possible objec-tions and anticipate counterarguments by incorporating them in their decisions (e.g. Amossy 2000; Mazzi 2007).
The notion of polyphony (or dialogism) was originally intro-duced by Mikhail Bakhtin (1929/1984) with regard to the novel and later expanded to embrace other forms of linguistic commu-nication (Bakhtin 1981). It postulates the presence of different ‘voices’ in ‘speech utterances’ (in Bakhtin’s terminology), and was taken up and elaborated by various scholars in linguistics, and in particular Ducrot (1984), and later the Scandinavian ScaPoLine group (Nølke/Fløttum/Norėn 2004) and Bres and Nowakowska (Bres 1999; Bres/Nowakoska 2005).
In this Chapter it will be shown that polyphony as the property of discourse to incorporate multiple layers of other discourses is especially relevant to judicial discourse, where it is realized by means of a range of different linguistic devices, some of which are evidently dialogic (cf. Fairclough's manifest intertextuality: 1992: 117-123; cf. also Martin/White 2005), while others are less manifestly so (Bres/Nowakoska 2005: 139).
Taking as a starting point the examination of a corpus of Judg-ments issued by the UK Court of Appeal, the UK Supreme Court and the House of Lords, the presentation will identify and discuss some of the most noteworthy polyphonic devices de-ployed in them (e.g. concession, language reports irony, presup-position, comparison, rectification, etc.), examining their discur-sive function (cf. Garzone 2012; Garzone/Degano 2012).

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
