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

LDP : location discovery protocol for data center networks
Full text linkData center architectures are gaining more and more interest nowadays due to the emerging need for hosting tens of thousands of workstations with significant aggregate bandwidth requirements. The underlying network architecture of a data center typically consists of a tree of routing and switching elements that count to thousands of components for the large-scale data centers that are deployed today. Recent research activity has been focusing on many of the challenges that one is faced with on building such large in scale data centers, such as scalability issues, dealing with the possibly inherent non -uniformity of the bandwidth among data center nodes, minimizing the actual cost of building and deploying these data centers, reducing the cabling complexity involved with interconnecting the routing and switching elements that a data center is composed of and coming up with efficient forwarding and routing mechanisms to be used within the data center. In this context, many solutions to efficient forwarding and routing have been proposed recently that take advantage of a switch' s relevant location in the global topology. This study focuses on a specific challenge regarding data center architectures, which is that of providing a plug and play functionality to a data center's switches so that no such switch will require any kind of human intervention or physical device configuration for figuring out its location in the underlying network architecture. We present a scalable, distributed and efficient Location Discovery Protocol for data center network topologies (LDP). Our solution is generic, allowing for any kind of multi-rooted tree architecture to be used when interconnecting the switching elements that constitute the core of a data center networ
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
Mobile code offloading for multiple resources
Full text linkMobile devices are becoming pervasive, yet a persistent gap in hardware capabilities still separates them from desktop machines. To bridge this gap, recent research has turned to cloud-assisted execution as a way of leveraging remote resources to enhance application performance. Code-offloading systems automatically partition applications across resource-constrained devices and more powerful remote nodes to improve execution. Existing approaches, however, only focus on compute resources, ignoring memory and network limitations in mobile environments. In doing so, they prevent mobile applications from taking advantage of the larger memory and richer networking capabilities of cloud-based nodes. At the same time, they face the challenge that a large runtime overhead may offset the benefits of offloaded execution and support only applications written in managed programming languages with substantial runtime support. In this thesis, we propose three new static code-offloading approaches that exploit all three remote resources—compute, memory and network:
(1) Compute-focused offloading enables applications written in unmanaged programming languages with only rudimentary runtime support to benefit from remote compute resources. Using offline dynamic profiling to analyse runtime behaviour, it derives a partitioning that reduces response times by offloading compute-intensive functionality to the remote node.
(2) Memory-focused offloading partitions application state across nodes to alleviate memory constraints and reduce offloading overheads by permanently collocating data and computation. To handle network failures, it uses a snapshot-based fault tolerance mechanism to back up state changes locally and a user-level virtual memory scheme to support execution with large state sizes after failure. (3) Network-focused offloading partitions mobile client applications across mobile devices and nodes at edge locations of a mobile network to minimise network traffic in radio access networks. It (i) discards unused data returned by coarse-grained API calls to Internet backend services and (ii) tunes binary object prefetching strategies to transmit only the objects that are used on the device.Open Acces
