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
The Italian version of the Hand Mobility in Scleroderma (HAMIS) test: evidence for its validity and reliability
No full textOBJECTIVES:
In systemic sclerosis (SSc), hand involvement is frequent and leads to prominent disability. The Hand Mobility in Scleroderma (HAMIS) test is a hand function test for SSc patients assessing the movements included in an ordinary range of motion examination. Our aim is to validate the Italian version of HAMIS, by assessing its test-retest reliability, internal consistency and external consistency in Italian SSc patients.
METHODS:
The Italian version of HAMIS was administered to 40 SSc patients. HAMIS was translated according to international procedures. Test-retest reliability was assessed by intra-class correlation coefficient (ICC), internal consistency by Cronbach's alpha and external consistency by comparison with Cochin Hand Function Scale (CHFS), fist closure, hand opening, HAQ.
RESULTS:
HAMIS showed a good testretest reliability (ICCs=0.99 for right and left hand) and internal consistency (Cronbach's α=0.94 for right and 0.93 for left hand) for both hands. A good external consistency was confirmed by the correlation of right and left hand HAMIS with CHFS (p<0.0001, in both cases); fist closure of homolateral hand (p<0.0001 in both cases), opening of homolateral hand (p<0.05 and <0.005, respectively), HAQ (p<0.001 in both cases). HAMIS scores for right and left hands were 7.95±6 .68 and 7.5±6.60 (p=NS), respectively. HAMIS scores for both hands were higher in dSSc and in patients with hand arthritis and flexion contractures.
CONCLUSIONS:
HAMIS is a hand function test measuring hand disability in SSc. Our results support its validity and reliability in Italian SSc patients
Insights Into Late-Onset Rheumatoid Arthritis (LORA): Characteristics (Clinical and Imaging), Comorbidities, and Therapeutic Targets
No full textLate-onset rheumatoid arthritis (LORA) is defined as rheumatoid arthritis (RA) manifesting after the age of 65 years, although the terminology remains somewhat ambiguous. With the advent of a super-aging society and extended life expectancies, a significant increase in the incidence of LORA is anticipated. In comparison to young-onset RA (YORA), LORA is predominantly characterized by a higher incidence of acute onset, augmented disease activity and constitutional symptoms, a propensity for systemic manifestations, increased erythrocyte sedimentation rate at disease onset, reduced seropositivity, a predilection for involvement of large and proximal joints with symptoms resembling polymyalgia rheumatica, a higher frequency of erosive disease, and a more evenly distributed gender ratio. Elderly individuals, particularly those with multimorbidity and on multiple medications (polypharmacy), are at an elevated risk of developing geriatric syndromes, including sarcopenia and frailty. The response to TNF inhibitors in elderly individuals with RA is generally comparable to that in younger patients, though it may be slightly diminished. The duration of the disease appears to have a more pronounced impact on outcomes than the patient's age. For the management of LORA, it is critical to adopt a patient-specific approach. Non-frail LORA patients who are otherwise aging healthily should receive aggressive treat-to-target management. Conversely, in pre-frail and frail patients, the therapeutic focus should be on averting the progression of irreversible geriatric conditions. The confluence of multimorbidity, polypharmacy, and geriatric syndromes in this patient population necessitates a tailored therapeutic approach to maintain patient autonomy and functional status

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
