    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The 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

    “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 link
    We 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

    Play goes digital : role of early childhood educators

    No full text
    The age of a child determines the kind of play he/she will engage in, for example, solitary play, constructive play, parallel play, and so on. Many of these conceptualisations tend to consider play as a universal construct unfolding in predictable ways as per the child's biological age. However, what is missing from this thinking is how the increasing access to new media technologies and tools, such \ud as tablets, mobile phones and computers, has altered play opportunities for children

    M.Sc. (SPMS)In the present work, we have studied the effect of Ce-doping on the structural and dielectric properties of BiFeO3 ceramic. The phase characterization of BiFeO3 is carried by X-ray Diffraction. The variation of dielectric constant and dielectric loss with temperature (400-5000 C) in the frequency range of 100Hz-1 MHz is studied.School of Physics and Material Science, Thapar University, Patial

    Agrarian Reforms, Modes of Production and Farm Bills 2020 in Punjab

    Full text link
    In the light of historical developments and the nature of Punjab’s agrarian milieu, this paper examines the latest agrarian intervention proposed by the State- ’Farm Bills 2020’. The paper begins with an analysis current mode of production in Punjab by investigating factors like institutional credit market, land prices, accumulation of capital, input-output ratio, commodification, commercialization, labor functions, and technological modernity. This is followed by a discussion on the historical background of agrarian reforms in Punjab. This discussion attempts to identify causes of proliferation and impacts of Arhtiya class of Intermediaries. In this way, the present paper seeks to study the nature of the intervention purported by the Farm Bills in terms of its interaction with the transforming social contradictions, and possible implications on the socio-economic framework, rural sociology, and existing agrarian relations in Punjab

    What teacher needs to know about STEM-Nonfiction

    Full text link
    What educators need to know about STEM nonfiction is covered in this presentation. Teaching subject like maths, science, technology, and engineering isn’t always mean going to lab or completing written worksheets. Different non-fiction book types are preferred by different children, and some students are better suited to specific subjects than others. Unlike traditional non-fiction, there isn\u27t just one set of guidelines for selecting books for learners. Therefore, understanding the categories of STEM nonfiction can help educators with exploring science, technology, engineering, and maths

    Neutrino oscillations :Short,Long and Magic baselines

    No full text
    MS, SPMSNeutrino oscillations are signature of small masses of neutrinos which are considered to be mass less in standard model, thus it points going beyond standard model. Thus determination of neutrino oscillations is important for formulating theories beyond standard model. In this work, we study phenomenon of two and three flavour neutrino oscillations giving theoretical frame on solar and atmospheric neutrino oscillation probabilities for three generation case, we also discuss currently going neutrino parameters and some detectors, reactors working on neutrino oscillations. After that discuss about baselines (short, long and magic) studying oscillations using different parameters (L,E),then plots for electron muon and taun are drawn with analysis and further motivation in neutrino oscillation
