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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Development of Solution Methodologies for Multi-Product, Multi-Component, Production-Inventory Planning Problem in a Component Remanufacturing Environment considering Backorders and Quantity Discounts
No full textClosed loop supply chain has been an area of research which has evolved over the years. This thesis aims to address a problem in this domain, specifically from the perspective of an Original Equipment Manufacturer (OEM) in the discrete product manufacturing industry. The OEM seeks to involve remanufacturing as part of its business process wherein its major concern is to satisfy demands for multiple products from customers. To satisfy the demands of products, the OEM needs to assemble the products using multiple components. These components can be obtained from multiple sources viz: manufacturing, remanufacturing, and purchasing from external suppliers.
Incorporating remanufacturing is beneficial for the OEM as it aids in reducing energy consumption and the overall costs. Specifically, the remanufacturing cost is observed to be generally between 40–60% of the manufacturing cost and consuming only 20% of a firm’s effort. Moreover, due to technological constraints, certain components do exist, which cannot be made in-house. Such components need to be only purchased from external suppliers who offer quantity discounts, to motivate the OEM to buy in bulk. Thus, the OEM needs to consider this aspect too while making the purchase decision. Also, at times, if the complete demand for products cannot be satisfied in a said period due to capacity restrictions, the unsatisfied portion of the demand is backordered to future periods. Furthermore, priority is given to satisfy this backordered demand before satisfying current demand of that period.
The OEM thus needs to plan the production and inventory adequately and optimally in such a way that its overall profit is maximized subject to various constraints. This thesis predominantly intends to aid the OEM in this process by addressing a Multi-Product (MP), Multi-Component (MC), Production-Inventory Planning problem (PIPP) in a Component Remanufacturing Environment (CRE) considering Backorders (BO) and Quantity Discounts (QD), [shortly referred as MP-MC-PIPP in CRE with BO and QD], with an objective of maximizing total profit for the OEM. This research problem is addressed by proposing three research objectives.
As part of the first research objective, an Integer Linear Programming (ILP) model is developed with an objective of maximize the OEM profit. The computational complexity of the developed ILP model is studied by varying values of few parameters, one at a time, and empirically observed that the research problem defined in this study is computationally intractable to obtain optimal solution for large scale problem instances. Due to this computational intractable nature of the ILP model, 20 variants of Greedy Heuristic Algorithm (GHA), are proposed as the second research objective of the study. To arrive at the multiple variants of GHA, the overall research problem is split into four integrated decision problems, namely, the, Product Assembly-Backorder (PAB) Problem, Dismantling Products – Remanufacturing Components (DisP-RMC) Problem, Manufacturing Component (MC) Problem and Purchasing Component with Quantity Discount (PCQD) Problem. Subsequently certain decision rule(s) are proposed for solving each of these decision problems. The 20 variants of the GHA are thus proposed by having a combination of the decision rules proposed for the various decision problems. Furthermore, the performance evaluation of each of the 20 variants of GHA is analyzed both empirically and statistically, by developing a suitable computational experiment [that is, by (a) defining experimental design, (b) identifying benchmark procedures, and (c) identifying suitable performance measures] and the 3 top better performing variants of GHA are identified.
In the last objective of the study, 12 variants of simulated annealing (SA) algorithm are implemented considering the solution obtained from each of the top 3 variants of the proposed GHA as initial solution to the SA algorithm. Before implementing the SA algorithm, the values of the SA parameters are set by following the Taguchi approach. Subsequently, the performance of the proposed 12 variants of SA is evaluated both, empirically and statistically and it is observed that applying the SA algorithm considering the solution obtained from the top performing proposed GHA is improving the loss of optimality considerably.
The practical implication of this study could be to devise, develop, and provide solution approaches to the OEM for the MP-MC-PIPP in CRE with BO and QD to maximize their optimal profits. Additionally, this will aid the OEM to efficiently (i) plan their inventories, (ii) deal with the aspect of backorders and (iii) choose their component purchase plan including the component suppliers in a wise manner.
However, there are certain limitations to this study, such as (a) the problem is addressed from a deterministic problem setting, (b) capacity restrictions for inventory and scrapping are not considered and (c) the input data is generated based on an experimental design and not the real data collected from OEM. In addition to overcoming the limitations mentioned in this thesis, there are many immediate future research directions for interested future researchers such as (a) developing alternate heuristic approaches and/or applying other metaheuristic algorithms for the research problem defined in this study, (b) developing an appropriate lower bound which can act as a better benchmark solution procedure instead of the estimated optimal solution and (c) considering environmental and social objectives along with the economic objectives
Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
