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
Validation of the Italian version of the Coma Recovery Scale-Revised (CRS-R)
No full text"PRIMARY OBJECTIVE:. To validate the Italian version of the Coma Recovery Scale-Revised (CRS-R).. METHODS:. Two observers applied the Italian version of the CRS-R to selected patients. On day 1, observer A and B independently scored each patient; the comparison of their observations was used to evaluate inter-observer agreement. On day 2, observer A completed a second evaluation and the comparison of this observation with that obtained on day 1 by the same observer was used to evaluate test-re-test agreement. For each evaluation, also diagnostic impression (vegetative state\/minimally conscious state) was reported.. RESULTS:. Thirty-eight patients were evaluated (mean age ± SD, 58.9 ± 13.8 years). Inter-observer (ρ = 0.81; p < 0.001) as well as test-re-test agreement (ρ = 0.97; p < 0.001) for the total score was high. Inter-observer agreement was excellent for the communication sub-scale, good for the auditory, visual and motor sub-scales and moderate for the oromotor\/verbal and arousal sub-scales. Test-re-test agreement was excellent for the visual, motor, oromotor\/verbal and communication sub-scales, good for the auditory sub-scale and moderate for the arousal sub-scale. When considering the diagnostic impression, inter-observer agreement was good (κ = 0.75; p < 0.001) and test-re-test agreement was excellent (κ = 0.92; p < 0.001).. CONCLUSIONS:. The Italian version of the CRS-R can be administered reliably and can be also employed to discriminate patients in vegetative and in minimally conscious state.
Developing ICF core set for subjects with traumatic brain injury: an Italian clinical perspective
No full textAim. The objective of this empirical study is to describe functioning and health of individuals with traumatic brain injury (TBI) and to identify the most common problems using the International Classification of Functioning Disability and Health (ICF). The specific aims are to describe the prevalence of problems in functioning as defined by the ICF of individuals with TBI, and to identify categories that explain most of the variance of the external standards.Methods. 261 TBI patients from 24 Italian centres members of the Italian Network were consecutively enrolled into the study between July 2008 and January 2009. The study was conducted as an empirical cross-sectional study.Results. The Extended ICF checklist captures the problems of TBI patients: many problems were reported within body function and body structure, but the most impaired categories were in Activity and Participation domain: the impaired categories reflect restrictions in challenging activities or activities related to later stages of recovery. The Environmental Factors in ICF were most frequently scored as facilitators: the support of the family is the most important environmental factor emerged, together.Conclusion. This study describes and identifies the most common problems in functioning of persons with TBI in an Italian sample. It emphasizes the importance of approaching the description of functioning and disability from a comprehensive perspective including not only body functions and structures but also activities and participation domains and environmental factors
Optimal positioning of continuous optical fiber sensors for the modal analysis of turbine blades with optical backscatter reflectometer technology
No full textThere are many methods described in the literature for the modal analysis of turbine blades, using well established technologies. The aim of this paper is the introduction of a new method, based on continuous optical fiber sensors and on optical backscatter reflectometer (OBR) technique. Contrary to other methods, the sensor is not invasive and all the measuring points are aligned in sequence on the same wire (i.e. the
same optical fiber) characterized by a limited length. In the literature, many optimal positioning methods for the sensors have been proposed, but none of them considers sensors arranged sequentially along the same wire, limiting to independent sensors, such as strain gauges or accelerometers. On the contrary, in this paper, an optimal method is proposed and illustrated in detail to arrange the optical fiber along the blade to perform the modal analysis. Finally, some numerical and experimental tests performed on a blade
will be presented
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

No full textAppropriate 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
