Gaussian entanglement witness and refined Werner-Wolf criterion for continuous variables
Get PDFWe use matched quantum entanglement witnesses to study the separable criteria
of continuous variable states. The witness can be written as an identity
operator minus a Gaussian operator. The optimization of the witness then is
transformed to an eigenvalue problem of a Gaussian kernel integral equation. It
follows a separable criterion not only for symmetric Gaussian quantum states,
but also for non-Gaussian states prepared by photon adding to or/and
subtracting from symmetric Gaussian states. Based on Fock space numeric
calculation, we obtain an entanglement witness for more general two-mode
states. A necessary criterion of separability follows for two-mode states and
it is shown to be necessary and sufficient for a two mode squeezed thermal
state and the related two-mode non-Gaussian states. We also connect the witness
based criterion with Werner-Wolf criterion and refine the Werner-Wolf
criterion.Comment: 11pages, 2 figure
(Inter)mediality and the Study of Literature
Get PDFIn his article (Inter)mediality and the Study of Literature Werner Wolf elaborates on the intermedial turn and asks whether this turn ought to be welcomed. Wolf begins with a discussion about the definitions of medium and intermediality and the impact these concepts and practices exert on scholarly, as well as student competence. He argues that despite of the fact that literary studies ought not simply turn into media or cultural studies, mediality and intermediality have become relevant issues for both teaching and the study of literature especially in the fields of comparative literature and (comparative) cultural studies. Following his postulate of the relevance of mediality and intermediality in the study of literature, Wolf explores ways of integrating the said concepts and practices into the study of literature and, in particular, their integration in the field of narratology. In this context, Wolf presents a typology of intermedial forms
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
