Ramchandra gandhi the gachibowli period
No full textThis exposition of the philosophical position developed in Ramchandra Gandhi’s later work is essentially built around his Gachibowli lectures. From January to April 1992, he spoke twice a week at the Department of Philosophy on the University of Hyderabad’s Gachibowli campus, at what was then the edge of Hyderabad city. e location suffices to identify these lectures uniquely; hence this talk of ‘the Gachibowli period’. At the time of his regular, and longer, full-time appointment at the university in the 1970s, the philosophy department was located at the university’s Golden reshold campus in the heart of town
Non-leaky conductor-backed coplanar waveguide-fed microstrip patch antennas
No full textMicrostrip patch antennas and their various existing multi-layer feeding configurations are studied and a new more useful, albeit complex feeding configuration is suggested and its full-wave analysis is presented along with the experimental verification. Simple microstrip patch antennas are analysed first and an improved treatment of microstrip patches based on the segmentation method and cavity model is presented for probe-fed and microstripline-fed patches. The full-wave analysis of microstrip patches using the moment method in spectral domain is presented for the case of probe-fed and microstripline-fed patches and the relevant Green's functions are given. The full-wave analysis of the microstripline-fed aperture coupled patch and coplanar waveguide-fed patch is also presented along with the relevant Green's functions. The drawbacks of these existing feeding configurations are noted, particularly aiming for easier integration of the patch with microwave circuits.In view of easier integration, a conductor-backed coplanar waveguide-fed patch suggested earlier could have been highly suitable. The dangers of this arrangement, mainly the leakage of power, are pointed out with the help of full-wave analysis and modifications to avoid the leakage are studied. A particular non-leaky conductor-backed coplanar waveguide configuration is selected and utilised to excite the patch through an electrically small aperture in the back-plane. The relevant Green's functions are derived and the evaluation of complex propagation constant and characteristic impedance are given in spectral domain. The full-wave analysis of such a non-leaky conductor-backed coplanar waveguide-fed rectangular microstrip patch configuration is presented with experimental verifications. The effects of coupling aperture and slot dimensions are also studied. The advantages of this configuration over the existing ones are presented along with the scope of its applications.</p

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
