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
Landscape, Sources and Architecture at the Archaeological Remains of Achaemenid Sistan (East Iran): Dahan- i Ghulaman
No full textThe author deals with the important archaeological remains in Sistan of Dahan.e Ghulaman. The region located along the border between Iran and Afghanistan (between 30°18’ and 31°21’ northern latitude and 61° and 61°50’ eastern longitude), constitutes today, together with the southern region of Baluchistan, one of the largest provinces (ostān) of the Islamic Republic of Iran. The province, is bordered by the province of Khorasan and Afghanistan to the north, Afghanistan and Pakistan to the east, the Sea of Oman to the south, the Kerman province to west and the Hormozgān province to south-west.
From a morphological point of view, Sistān represents the westernmost portion of system of lagoons constituting the Hāmun Lake, whose eastern part is administratively within the boundaries of the Afghan province of Nimrūz.
The scholars by now agree that the first historical reference both to the territory around the Hāmun Lake and to the Helmand River is that of the inscription of Darius I (522-486 a.C.) at Bisotun, in which the name of the country and its inhabitants are attested in the old-Persian form z-r-k (to be read Zrānka), apparently its original name. This form finds a direct reflex in the Elamite (“sir-ra-an-qa”; Cameron 1960), Babylonian (“za-ra-an-ga”) and Aramaic (“srng/srnķ”) version of the same inscription. Some toponyms and ethnonyms attested in some Greek sources (Zarángai, Zarangaîoi, Zarangianế in Arrian and Hysidorus of Charax; Sarángai in Herodotus) and in Latin (Zarangae in Pliny) derive indirectly from this origin. Instead of this native form, characterized by the non-Persian sound “z-”, in the greater part of the Greek sources (mainly those dependent on the biographers of Alexander; Schmitt 1996, 535) and in Latin variations one finds the hyper-corrected Persianized form *Dranka/Dranga which are characterized by the Persian sound “d-”: Drángai, Drangế, Drangēnế, Drangi(a)nế (Ctesias, Polybius, Strabo; Diodorus; Ptolemy; Arrian; Stephan of Bysanz), Drangae, Drangiana, Drangiani (Curtius Rufus, Pliny, Ammianus Marcellino, Justin).
In the complex frame of the formative processes, political nature and the real extension of the Achaemenid Empire, the discovery of Dāhān-e Ghūlāmān in the Iranian Sīstān basin (eastern Iran), by the Italian Archaeological Mission of IsMEO, and the related excavations that followed in the 60s of the last century, formed and still today occupy are a very important and decisive stage.
In this particular geo-environmental context, the macroscopic architectural remains of Dāhān-e Ghūlāmān that stand out in a very characteristic and particularly suggestive way, belong to a real city. Thus was proposed, at the time of discovery, to be the old Zarin of the classical sources, the capital of the Achaemenid satrapy of Drangiana (Zrānka of the imperial inscriptions), and dated between the end of the sixth and the fourth century BC. They are the only “urban” remains until now known from that time in the plateau. Even the new tests conducted in the recent years by the Iranian Cultural Heritage Organisation in the city and in particular in the building no 15 seem to confirm the overwhelming importance of the site
Information-theoretic and stochastic methods for managing the quality of service and satisfaction in healthcare systems
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This research investigates and develops a new approach to the management of service quality with the emphasis on patient and staff satisfaction in the healthcare sector. The challenge of measuring the quality of service in healthcare requires us to view the problem from multiple perspectives. At the philosophical level, the true nature of quality is still debated; at the psychological level, an accurate conceptual
representation is problematic; whilst at the physical level, an accurate measurement of the concept still remains elusive to practitioners and academics. This research focuses on the problem of quality measurement in the healthcare sector. The contributions of this research are fourfold: Firstly, it argues that from the technological point of view the research to date into quality of service in healthcare has not considered methods of real-time measurement and monitoring. This research identifies the key elements that are necessary for developing a real-time quality monitoring system for the healthcare environment.Secondly, a unique index is proposed for the monitoring and improvement of healthcare performance using information-theoretic entropy formalism. The index is
formulated based on five key performance indicators and was tested as a Healthcare
Quality Index (HQI) based on three key quality indicators of dignity, confidence and
communication in an Accident and Emergency department. Thirdly, using an M/G/1 queuing model and its underlying Little’s Law, the
concept of Effective Satisfaction in healthcare has been proposed. The concept is based on a Staff-Patient Satisfaction Relation Model (S-PSRM) developed using a patient satisfaction model and an empirically tested model developed for measuring staff satisfaction with workload (service time). The argument is presented that a synergy between patient satisfaction and staff satisfaction is the key to sustainable improvement in healthcare quality. The final contribution is the proposal of a Discrete Event Simulation (DES)
modelling platform as a descriptive model that captures the random and stochastic
nature of healthcare service provision process to prove the applicability of the proposed quality measurement models
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
