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
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

Critiques in the Margins: Contextualizing Mughulṭāy b. Qilīj’s (d. 762/1361) Gloss on the Sīra
No full textThis article examines Mughulṭāy b. Qilīj’s (d. 762/1361) al-Zahr al-bāsim fī siyar Abī al-Qāsim, a ḥāshiya (gloss, marginal notes) on ʿAbd al-Raḥmān al-Suhaylī’s (d. 581/1185) commentary on Ibn Isḥāq’s Sīra. Drawing on evidence from Mamlūk-era chronicles, biographical dictionaries, and commentarial introductions, it analyzes Mughulṭāy b. Qilīj as a historical figure and the context and content of his work. This is done in order to demonstrate how commentaries and glosses are deeply related to the scholarly and cultural life of the period. These resources testify to the antagonistic relationship between Mughulṭāy and his opponents and to the ensuing rivalry between them. Hence, this article seeks to examine the correlation between his personality and the rationale for his commentary, to determine the reasons behind his choice of text to write a gloss on and his sustained and harsh criticism against al-Suhaylī and his scholarly legacy
A pilot study of reliability and validity of Turkish version of West Haven-Yale Multidimensional Pain Inventory in patients with low back pain
No full textBackground: West Haven-Yale Multidimensional Pain Inventory (WHYMPI), used in the evaluation of patients with chronic pain including behavioral and cognitive assessment, is a multidimensional pain scale consisting of three main sections and 12 subscales. The validity of this inventory has been supported by various study results of confirmatory and exploratory factor analytic procedures. The aim of our present study was to investigate the validity and reliability of the Turkish form of the West Haven-Yale Multidimensional Pain Inventory (WHYMPI-T). Methodology: 41 patients, with a minimum 3 mon history for chronic non-specific low back pain, without previous surgical history, neurological and rheumatic diseases, and without communication problem; completed Brief Pain Inventory (BPI), McGill Pain Questionnaire (MPQ), Beck Depression Inventory (BDI) and the Short Form-36 (SF-36) scales. The measurements were repeated in fifth days. Results: Significant difference between WHYMPI-T lower and upper group averages was found. Internal consistency analysis of the scale, Cronbach's α coefficient ranged from 0.93 to 0.99 for B and C sections. All the items of A, B and C sections were found compatible with each other in the item analyses and scale test-retest results were congruent with each other. Between WHYMPI-T subscales and BPI, MPQ, BDI, SF-36 scales, a positive correlation was observed. Conclusion: The results of our study confirm that WHYMPI-T is a valid and reliable instrument which can be used for the evaluation of chronic non-specific low back pain.

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
Introduction to Hybrid Systems - Yildiz Technical University
No full textIEEE EUROCON Conference -- JUL 01-04, 2013 -- Zagreb, CROATIA -- IEEE, IEEE Croatia Sect, IEEE Reg 8, FEREnergy has always been an important factor for socio-economic development of humans. Most of the energy is generated from fossil fuels in the world. Nevertheless, environmental aspects and depleting of fossil fuels causes increase of renewable energy utilization. The produced energy from renewable energy resources are transferred to grid or used in stand-alone systems. As energy generation depends on environmental conditions, efficiency and energy potential of renewable energy systems changes according to region of installation. In this study, introduction of the solar-wind-battery hybrid system constructed in Davutpasa Campus, Yildiz Technical University, and future work for the system are presented.Yildiz Technical UniversityYildiz Technical University [2012-04-02-KAP04]Authors would like to thank the Yildiz Technical University for full financial support of the project namely Reliability Analysis of Small Scale Hybrid Wind and Solar Energy Systems: A Case Study of Davutpasa Campus, Project No: 2012-04-02-KAP04
Hepatitis B virus vaccination in children with steroid sensitive nephrotic syndrome: Immunogenicity and safety?
No full textWe investigated the efficacy and safety of Hepatitis B vaccine (HBVac) in steroid sensitive nephrotic syndrome (SSNS) children. 41 patients with SSNS and 30 controls were vaccinated with HBVac(Engerix B (R)). Patients were divided into 3 subgroups:full dose steroid users, alternate-day steroid users and steroid non-users. Seroconversion rate was lower in steroid users than non-users at the 6th(p = 0.015) and 12th(p = 0.036) months. Antibody to Hepatitis B surface antigen(HBsAb) titers were significantly different between subgroups and controls at the 15th month. However, HBsAb and response rates were not different between subgroups at the 12th and 15th months (p>0.05). Five patients were unresponsive to HBVac. Relapse rates after the vaccination were higher than those in the prevaccination period (p = 0.002). HBVac is less effective in producing immune response in SSNS children with steroid therapy. HBVac may trigger relapse in some patients. We recommend HBVac to SSNS children with low dose steroid therapy or after steroids are discontinued. (C) 2013 Elsevier Ltd. All rights reserved
