Self-archiving practice and the influence of publisher policies in the social sciences
No full textAuthors in different disciplines exhibit very different behaviours on the so-called ‘green’ road to open access, i.e. self-archiving. This study looks at the self-archiving behaviour of authors publishing in leading journals in six social science disciplines. It tests the hypothesis that authors are self-archiving according to the norms of their respective disciplines rather than following self-archiving policies of publishers, and that, as a result, they are self-archiving significant numbers of publisher PDF versions. It finds significant levels of
self-archiving, as well as significant self-archiving of
the publisher PDF version, in all the disciplines
investigated. Publishers’ self-archiving policies have
no influence on author self-archiving practice
Effect of Co-Solvents on Bulk And Interfacial Characteristics of Room Temperature Ionic Liquids
Get PDFIonic liquids (ILs) are special class of molten salts constituted by large and
asymmetric organic cations and inorganic or organic anions, with melting
temperatures below 100oC. Due to the large size and the conformational flexibility of
constituent ions, ILs present low lattice enthalpies and large entropy changes upon
melting which favour the liquid state. ILs with melting point below ambient
temperatures are regarded as Room Temperature Ionic Liquids (RTILs). RTILs have
attracted increasing attention in recent years from both academia and industry
due to their interesting properties and potential applications. RTILs as a hybrid of
neutral and ionic entities, exhibit many unique physicochemical properties, such as
negligible volatility, nonflammability under ambient conditions, large liquidus range,
high thermal and chemical stability, wide electrochemical window, wide range of
densities and viscosities, high potential for recycling, high ionic conductivity, and
miscibility with a wide range of organic and inorganic compounds which
confer them their reputation as “green solvents” and make them a good alternative to
traditional organic solvents. In addition, the high polarity of the ILs
makes them to form very strong effective adsorption films and redy tribochemical
reactions, which contributes to their prominent antiwear capability. On account
of above mentioned specialities, RTILs have found wide applications in chemical
synthesis, catalysis, lubrication, thermal separation processes and electrochemistry
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
Handbook for Learning-centred evaluation of Computer-facilitated learning projects in higher education
Get PDFThis handbook supports a project funded by the Australian Government Committee for University Teaching and Staff Development (CUTSD). The amended project title is “Staff Development in Evaluation of Technology-based Teaching Development Projects: An Action Inquiry Approach”.
The project is hosted by Murdoch University on behalf of the Australasian Society for Computers in Learning in Tertiary Education (ASCILITE), as a consortium of 11 universities.
The rationale of the project is to guide a group of university staff through the evaluation of a Computer-facilitated Learning (CFL1) project by a process of action inquiry and mentoring, supported by the practical and theoretical material contained in this handbook
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Changing concepts in instructional procedures in high school history teaching since 1900
No full textThe purpose of this study is to trace the development of classroom instructional procedures in high school history teaching since 1900 as reflected in the professional literature of the period, with special reference to the teaching of United States history. The study provides an historical background of information by describing changing concepts in methods which (1) progressively focused attention on the teacher as a guide and manager of student learning activities rather than as a hearer of lessons; (2) gradually exemplified a change in the curricular image of high school history from content to be learned to a resource to be utilized; and (3) reflected the influence of a prevalent learning theory. ..
