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
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
Alexithymia as a possible specifier of adverse outcomes: Clinical correlates in euthymic unipolar individuals
No full textBackground: Alexithymia is a disabling condition frequently linked to major depressive disorder (MDD) and able to enhance symptoms severity and suicide risk. This study aimed to clarify whether patients with and without alexithymia may differ concerning illness presentation and clinical course, which is a major gap in the scientific literature. Methods: The present sample included 381 euthymic outpatients with MDD recruited at the Department of Neuroscience (DINOGMI), University of Genoa. The Toronto Alexithymia Scale (TAS-20) and additional rating scales (Clinical Global Impression (CGI), Hamilton Anxiety Rating Scale (HAM-A), Intent Score Scale (ISS) were administered to all participants. Results: Alexithymic patients were more likely to have lower educational level (11.6 ± 3.2 vs. 12.4 ± 3.4, p ≤.05), have used previous psychiatric drugs (85.7% vs. 72.8%, p =.001), use current antidepressants (84.7% vs. 69.4%, p = <.001), and have higher cardiological comorbid disorders (10.7% vs. 5.0%, p = ≤.05). After multivariate analyses, alexithymia was associated with lower educational level (OR=0.928, p =.05), and higher current antidepressants use (OR 2.302, p =.01); difficulties in identifying feelings were associated with lower educational level (p = ≤.005), higher psychiatric comorbidity (p = ≤.001), and previous psychiatric medications (p =.01). Furthermore, having a lower educational level remained the only factor associated with both difficulties in communicating feelings (p = ≤.001) and thoughts oriented to external context (p = ≤.005). Limitations: The study is limited by the small sample size and its cross-sectional nature. Conclusions: Alexithymia appears a useful specifier of adverse outcomes, associated with distinct socio-demographic and clinical characteristics. Its identification would allow to provide a more personalized care
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
Neurocognitive function and bipolar disorder: role of social cognition as a predictor [Funzioni neuropsicologiche nel disturbo bipolare: Ruolo della cognizione sociale come predittore di esito]
No full textÈ noto in letteratura che marcati deficit delle funzioni cognitive sono associati a forme gravi di disturbo bipolare (DB) e che tali disturbi possono influenzarne il decorso e predirne la prognosi. In questo studio abbiamo esaminato un gruppo di soggetti affetti da DB, al fine di verificare se l’outcome sintomatologico fosse correlato con la prestazione ottenuta nei test neuropsicologici. Sono stati studiati un gruppo di 28 soggetti affetti da DB. I diagnosticati secondo i criteri del DSM-IV sono tutti afferenti al SPDC a direzione Universitaria, ASL 04, L’Aquila. Metodi. I soggetti sono stati sottoposti a valutazione sintomatologica e neuropsicologica al primo contatto con la struttura (T0) e dopo 6 mesi (T6). Successivamente (dopo 6 mesi) il campione è stato suddiviso in due gruppi, un gruppo (n=11) con sintomatologia residua (Hamilton Rating Scale for Depression >8; Young Mania Rating Scale >6) e un gruppo (n=17) in remissione sintomatologica (Hamilton Rating Scale for Depression <8; Young Mania Rating Scale <6). Risultati. I risultati hanno evidenziato che nella valutazione psicopatologica, il gruppo con sintomatologia residua ha mostrato un peggior funzionamento globale. Per quanto riguarda le prove neuropsicologiche i risultati hanno evidenziato che al T0 entrambi i gruppi presentavano deficit neuropsicologici. Il gruppo con sintomatologia residua, tuttavia, presentava già al T0 maggiori deficit cognitivi nell’abilità di pianificazione e nelle prove relative alla cognizione sociale. Nel confronto a T6, il gruppo in remissione sintomatologica presentava una normalizzazione delle funzioni cognitive, mentre nel gruppo con sintomatologia residua i soggetti presentavano marcati deficit cognitivi. Conclusioni. La presenza di deficit cognitivi nelle fasi acute della patologia e la loro permanenza nelle fasi di parziale remissione del DB sono stati evidenziati in numerosi studi. Nella nostra ricerca abbiamo evidenziato un decorso sfavorevole nei soggetti che all’inizio del trattamento mostravano maggiori deficit cognitivi, individuando un ruolo predittivo di questi ultimi sulla prognosi del disturbo.Recovery in bipolar disorder is central to its definition but is rarely complete. Previous work has suggested that neuropsychological impairment and social cognition disorders, persist during, the euthymic state, but has been confounded partly by mild affective symptoms in remitted patients. The aim of our study is to characterize a neuropsychological profile in bipolar subjects in euthymic phase, in non remitted bipolar subjects and in schizophrenic subjects with an emphasis on social cognition and executive functioning. Methods. Seventeen euthymic and I I non remitted patients with bipolar disorders were compared with 64 schizophrenics patients and thirty healthy controls on neuropsychological and social cognition tasks. Results. All bipolar patients, like schizophrenics, were impaired on social cognition tasks, attention set shifting, verbal memory and executive functions. In euthymic bipolar group only social cognitive deficit survived controlling for mild affective symptoms. This deficit was related to progression of illness, but was nonetheless present in a subgroup of patients near illness onset, like in schizophrenics. Conclusions. Social cognition deficit may represent a neuropsychological vulnerability in schizophrenia and bipolar disorders. These findings add to the growing evidence that common mechanisms may contribute to bipolar affective disorder and schizophrenia
