No full textEditorial policy in reporting ethical processes: A survey of ′instructions for authors′ in International Indexed Dental Journals
No full textBackground: The International Committee of Medical Journal Editors expects authors to report if their studies were carried out in accordance with the International Ethical Guidelines and Declaration of Helsinki; and inform readers regarding the same. Aims: To determine the proportion of International Indexed Dental Journals reporting on ethical clearance for human and animal research, obtaining of informed consent and / or assent, and the conduction of research in accordance with the Declaration of Helsinki and International Medical Research, 2006. Settings and Design: A cross-sectional survey of ′instructions for authors,′ for analysis of editorial policy on ethical processes, was done. Materials and Methods: One hundred and twenty-six dental journals (which included 50 general and 76 specialties) were reviewed for reporting, with regard to the Ethical Committee Approval for human and animal researches, obtaining of informed consent / assent from the research participants, and research in accordance with the Declaration of Helsinki as well as International Medical Research 2006 were analyzed. Statistical Analysis Used: Descriptive statistics was used and results were expressed in percentages. Results: Of the 126 dental journals, 57 (45.23%) reported having obtained approval from the Ethics Committee, 33 (26.19%) were instructed about the Animal Ethics Committee approval, and 38 (30.15%) insisted on obtaining and reporting informed consent / assent. 41 (32.53%) journals expected authors to mention the research being conducted according to Declaration of Helsinki and and 3 (2.38%) journals required researches to be conducted in accordance with International Medical Research, 2006. Conclusions: A significant proportion of international indexed dental journals did not provide instructions to authors to report on the ethical approval, informed consent and / assent, and research conduction according to the Declaration of Helsinki as well as the International Medical Research, 2006

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
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

Variations on the Author
No full text“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
Experimental Enhancement of Heat Transfer Analysis on Heat Pipe using SiO2 and TiO2 Nano Fluid
No full textThis paper describes the enhancement of thermal performance of heat pipe using SiO2 and TiO2 nano fliuds. The experimentation explains about the effects of heat pipe inclination and heat input on the thermal efficiency and thermal resistance. Heat pipe is an advance type of heat exchanger which transfers huge amount of heat due to the effect of capillary action and phase change heat transfer principle. Recent developments in the heat pipe with high thermal conductivity through nano fluids. This paper reviews, influence of various factors such as heat pipe tilt angle, charged amount of working fluid, nanoparticles type, size, mass volume fraction and its effect on the improvement of thermal efficiency, heat transfer capacity and reduction in thermal resistance. The nano fluid preparation and the analysis of its thermal characteristics also have been reviewed. Arunkumar. G | Dr. P. Navaneetha Krishnan | Dr. T.
