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
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
Online scheduling for buffering problems
No full textIn a scheduling problem, tasks have to be assigned to resources in such a way that some specified objective is accomplished. Often times, tasks either can or have to be stored in a buffer before they are assigned to a resource. In these cases, a buffer management strategy has to constantly facilitate decisions as to which tasks to store in the buffer, which tasks to execute, and which tasks to delete from the buffer. If the tasks arrive over time, these decisions have to be made online, that is, without knowledge of the future. The predominant method to investigate online algorithms is the competitive analysis. An online algorithm is c-competitive if, for every input, the solution returned by the algorithm is at most by a factor of c worse than a solution given by an optimal offline algorithm. We study four different online scheduling problems, in which buffers are a crucial component, in a competitive analysis. First, we introduce and study reordering buffers, which are used to reorder a stream of tasks, requests, or jobs in such a way that they can be served more efficiently. This concept can be applied to various scheduling problems in order to improve performance. To demonstrate the power of reordering buffers and to show how they can be efficiently used, we apply reordering buffers to two exemplary scheduling problems. In the first problem, the reordering buffer is used to minimize the sum of the distances between consecutive elements in a sequence of points from a metric space. We design the first algorithm achieving a polylogarithmic competitive ratio for general metric spaces. In the second problem, the reordering buffer is used to obtain improved competitive ratios for the well-known online minimum makespan scheduling problem. For the identical machine model, we present matching upper and lower bounds on the competitive ratio which are significantly lower than the bounds for the classic online minimum makespan scheduling problem without reordering buffers. This is somewhat surprising considering that, for more than four machines, no tight bounds are known for the problem without reordering, despite the great effort that was spent on this problem. Buffers cannot only be an optional tool for improving performance for various scheduling problems, they can also be a problem-specific necessity. We investigate two different scheduling problems that are motivated by the problem of packet forwarding in network switches that have so-called Quality-of-Service (QoS) capabilities, i.e., switches which are able to treat different kind of packets with different priority. Since a network switch may not be able to instantly forward every arriving data packet, network switches are equipped with buffers to temporarily store not yet forwarded data packets. The different packet priorities in the QoS scenario are abstracted by assigning each packet a certain value which reflects its priority. A scheduling strategy is used to decide which packets from the buffers are to be sent at any given time. First, we study a scenario in which the buffers in the network switch have limited capacity and packets have to be sent in the order they arrive. Since the capacity of the outgoing link is also limited, buffer overflow events may occur. In case of a buffer overflow, packets have to be dropped and cannot be forwarded anymore. In order to avoid dropping very valuable packets, it can make sense to preemptively drop packets of lower value at a point in time where it would otherwise not be necessary to drop packets at all. The challenge is to design algorithms that drop the right packets at the right time to achieve the best possible performance. In the second scenario we study, the capacity of buffers is unbounded and packets can be sent in arbitrary order. However, each packet has a deadline by which it has to be either sent or dropped. In this model, there is a trade-off between sending packets which are to expire shortly and sending packets with large values. We completely solve both problems for the case that only two different packet values appear in the input sequence and improve the previous bounds for the general case. For the first problem variant, we study the so-called preemptive greedy strategy, which is currently the only algorithm achieving a competitive ratio below 2. We analyze this algorithm more carefully and show improved upper and lower bounds on the competitive ratio of preemptive greedy. For the second problem variant, we introduce the novel concept of suppressed packets and demonstrate the potential of this approach by, among other things, presenting an algorithm achieving the currently best known competitive ratio

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.
