Modern Arab-Islamic Scholarship on Ethics: A Reflective Contextualization
No full textWhile various Arab-Islamic modernist projects have targeted particular issues as the starting points for reforms, like politics and political authority, education, public culture, religious thought and institutions, some other projects have taken ethics as the starting point for any possible renewal, be it theoretical or practical, political or intellectual. This chapter contextualises this discussion, following this outline: first, it refers to the place of ethics in modern and contemporary Arab-Islamic reformist thought since the so-called renaissance (nahda) of the late 19th century, passing by the generation of scholarship of the first half of the 20th century, and reaching the new trajectories of thought in the second half of the 20th century, or the generation post-1967; general reference to classical works on ethics is made here, too; second, four major reflective notes on the trusteeship paradigm of Taha Abderrahmane as a modern robust theory of ethics are made, firstly, for clarifications of the scope of the paradigm, and secondly for opening new paths of reflection and research around the issue of ethics and modernity; finally, a summary of the book content is presented
DNA melting structures in the generalized Poland-Scheraga model
No full textThe Poland-Scheraga model for DNA denaturation, besides playing a central role in applications, has been widely studied in the physical and mathematical literature over the past decades. More recently a natural generalization has been introduced in the biophysics literature (see in particular Garel and Orland, 2004) to overcome the limits of the original model, namely to allow an excess of bases - i.e. a different length of the two single stranded DNA chains and to allow slippages in the chain pairing. The increased complexity of the model is re ected in the appearance of configurational transitions when the DNA is in double stranded form. In Giacomin and Khatib (2017) the generalized Poland-Scheraga model has been analyzed thanks to a representation in terms of a bivariate renewal process. In this work we exploit this representation further and fully characterize the path properties of the system, making therefore explicit the geometric structures and the configurational transitions that are observed when the polymer is in the double stranded form. What we prove is that when the excess of bases is not absorbed in a homogeneous fashion along the double stranded chain a case treated in Giacomin and Khatib (2017) then it either condensates in a single macroscopic loop or it accumulates into an unbound single strand free end
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Performance measures and preferences for fuzzy controllers design algorithms
No full textThis study defines practical performance measures for testing data-driven design algorithms for fuzzy controllers through the use of non-linear control functions. Also, criteria, which can be applied to these measures in order to determine preferences between data-driven algorithms, are discussed and a framework for solutions is proposed. After offering a summary of a new algorithm for the design of Mamdani-type fuzzy controllers with emphasis on its design requirements, the algorithm is tested along with neuro-fuzzy and other design methods and performance comparisons are given. This is done by considering the defined measures and typical non-linear functions, which were adopted in published research. The new algorithm is found to provide better noise-free data-fitting than some published algorithms based on clustering, fuzzy partitions, and heuristics. However, the error values were found higher than those obtained using neuro-fuzzy and clustering-position-gradient approaches. In the practical noisy data case, however, the algorithm outperforms the combined fuzzy-neuro-least-square algorithm and the heuristic approach. This superiority is verfied based on performance measures related to noise-free data-fitting in the noisy data case, noise insensitivity, and generalization capability, the combination of these latter two measures and function shape representation.Al-Khatib M, 2003, FUZZY SET SYST, V134, P65, DOI 10.1016-S0165-0114(02)00230-0; BUCKLEY JJ, 1993, FUZZY SET SYST, V60, P1, DOI 10.1016-0165-0114(93)90283-N; Carse B, 1996, FUZZY SET SYST, V80, P273, DOI 10.1016-0165-0114(95)00196-4; Chen JQ, 1998, FUZZY SET SYST, V98, P319, DOI 10.1016-S0165-0114(96)00384-3; Delgado M, 1997, IEEE T FUZZY SYST, V5, P223, DOI 10.1109-91.580797; HORIKAWA S, 1992, IEEE T NEURAL NETWOR, V3, P801, DOI 10.1109-72.159069; JANG JSR, 1993, IEEE T SYST MAN CYB, V23, P665, DOI 10.1109-21.256541; JANG JSR, 1995, P IEEE, V83, P378, DOI 10.1109-5.364486; JANG JSR, 1992, IEEE T NEURAL NETWOR, V3, P714, DOI 10.1109-72.159060; Klawonn F, 1997, FUZZY SET SYST, V85, P177, DOI 10.1016-0165-0114(95)00350-9; Klawonn F, 1996, FUZZY SET SYST, V81, P331, DOI 10.1016-0165-0114(96)83710-9; Klir GJ, 1995, FUZZY SETS FUZZY LOG; Koczy LT, 1997, FUZZY SET SYST, V85, P203, DOI 10.1016-0165-0114(95)00348-7; Lee CW, 2003, FUZZY SET SYST, V137, P297, DOI 10.1016-S0165-0114(02)00344-5; LEE J, 1993, FUZZY SET SYST, V56, P127, DOI 10.1016-0165-0114(93)90138-8; Li Y, 2002, FUZZY SET SYST, V127, P85, DOI 10.1016-S0165-0114(01)00154-3; Lin YH, 1997, IEEE T FUZZY SYST, V5, P614; NOMURA H, 1992, IEEE INTERNATIONAL CONFERENCE ON FUZZY SYSTEMS, P203, DOI 10.1109-FUZZY.1992.258618; Nozaki K, 1997, FUZZY SET SYST, V86, P251, DOI 10.1016-0165-0114(95)00413-0; Saade J.
