Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
FADI: a fault-tolerant environment for open distributed computing
No full textFADI is a complete programming environment that serves the reliable execution of distributed application programs. FADI encompasses all aspects of modern fault-tolerant distributed computing. The built-in user-transparent error detection mechanism covers processor node crashes and hardware transient failures. The mechanism also integrates user-assisted error checks into the system failure model. The nucleus non-blocking checkpointing mechanism combined with a novel selective message logging technique delivers an efficient, low-overhead backup and recovery mechanism for distributed processes. FADI also provides means for remote automatic process allocation on the distributed system nodes
Correlation between fADI and PRNT methods for Yellow Fever vaccine virus.
No full text<p>fADI<sub>50</sub> were calculated from the Virus Attachment Indexes using a mathematical approximation model, more details in the text. The fADI titers for all the pre-vaccination sera samples were found very low. fADI displayed a considerable donor-to-donor variation in the capacity of post-vaccination donor sera to block attachment of vaccine strain 17DD of Yellow Fever virus to Vero cells (a). PRNT<sub>50</sub> data were obtained for the same sera samples independently by a commercial vendor (b). Control ELISA did not reveal a reduction of the reporter fluorescence signal, thus showing zero competition between the sera antibodies and the virus specific labeling antibodies used in the assay (c). A considerable positive correlation between the fADI and PRNT data for post-vaccination sera samples was found (d).</p
Ghayat al-amani and the life and times of al-Hadi Yahya b. al-Husayn: an introduction, newly edited text and translation with detailed annotation
No full textThe thesis is anchored upon a text extracted from an important 11th / 17th century Yemeni historical work. This text deals primarily with al-Hādī ilā 'I-Haqq, the founder of the Zaydī Imamate in the Yemen that lasted well over a thousand years. AI-Hādīs imamate, of considerable significance in itself, also coincides with one of the most turbulent periods of early Yemeni mediaeval history. The- edited Arabic text, with its accompanying apparatus criticus. Is to be found at the opposite end of this volume. The Introduction considers various aspects of Imam al-Hadī’s life, religious ideas and aspirations and matters directly connected with the edited text and the work of which it forms a part. Among the most important subjects discussed are the MSS used in the production of the edited text, the problem concerning the authorship of Ghāyat al-amānī and the relationship of the latter work to Anbā' al-zaman. A short biography of al-Hādī is provided, together with a treatment of the historical background to ai-Hādīs imamate. The introduction also describes the editorial method followed with regard to the text, and certain key personal names and toponyms are dealt with there. The method employed by the author of the Ghāyat is to record the events of any one year by Itself. I have translated one year at a time and then followed it by the annotations appertaining to it. It is hoped that by means of these annotations. (some of which through necessity are quite detailed ), the text will be better understood. The numerous personages, tribal names and toponyms are considered, as well as problems concerning points of chronology and various matters of historical and religious significance. Specific comment is made upon certain interesting terms or any unusual or striking vocabulary. The thesis concludes with maps, genealogical tables and a comprehensive bibliography
Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe
Energy Aware Resource Allocation in Multi-Hop Multimedia Routing via the Smart Edge Device
No full textEnvironment sustainability, energy efficiency and computational reduction of computation time are recent stressing issues for the information and communication technologies (ICTs). Energy efficiency (EE) in particular is accounted for practical use of device to device (D2D) communications which is optimistic, and alternative architectural network especially for the cases where the infrastructure based communication is not possible. As a consequence, resource allocation for D2D communication plays a key role to address the issues related to battery lifetime and application quality of services (QoS). In this paper, a novel multi-hop routing is proposed to increase the energy efficiency of the D2D communication systems. In order to obtain a plausible solution, a combinatorial optimization is formulated. The purpose of this problem formulation is to achieve improved energy efficiency, throughput rate, resource utility, and packet delivery ratio as well as to reduce the computation cost. Network simulation demonstrates the efficiency of the proposed routing as compared to other existing techniques

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Proof of principle study for the fADI assay against different classes of viruses.
No full text<p>fADI displayed a significant sera concentration dependent blocking of virus attachment for polioviruses of serotyopes I, II and III (A), Dengue I, II, III and IV (C), Yellow Fever (E) and influenza California H1N1viruses (G) to Vero cells. The sera used in the demo experiments were standard hyper-immune sera specific to the corresponding viruses. Control ELISA (B, D, F and H) tests with those standard sera did not display any significant reduction in fluorescent signal thus showing very low or no competition between the sera antibodies and virus specific labeling antibodies used in the assay.</p
