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
Bringing dementia-care back into psychiatry
No full textDementia with over 46 million people suffering from it has become an illness which cannot be ignored. The confusion regarding whether dementia is a neurological or a psychiatric illness has been existing for a long. Conventionally, dementia has been viewed as a neurological illness with the organicity of the same being given utmost importance. However, we cannot ignore the vast contribution of psychiatry in the discovery of dementia. Furthermore, the new concept regarding psychiatric and neurological illnesses has challenged the fact that dementia is a completely neurological illness, especially considering the vast similarities between psychiatric disorders and dementia. This confusion regarding whether it is a neurological or a psychiatric illness has created difficulty in the management of these patients. The similarities between dementia and psychiatric disorders are visible at the level of localization of lesions, the symptoms, especially the behavioral and the psychotic symptoms, the methods of diagnosis, and the treatment strategies, especially the nonpharmacological ones, which are in fact more effective than the pharmacological strategies. The nonpharmacological aspects include not only behavioral strategies but also focus on breaking the bad news and addressing the caregiver burden and the legal aspects. All this puts a psychiatrist at an advantage in treating these patients, when compared to other specialists, given our expertise with history taking, mental status examination, pharmacological management of the behavioral issues, and especially nonpharmacological aspects
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
Are social theories still relevant in current psychiatric practice?
No full textCurrent psychiatric practice is being influenced by advances in the field of molecular biology, genetic studies, neuroimaging, and psychopharmacology and the approach has become "biological." Social theories of mental illness had once revolutionized the field of psychiatry and are currently being somewhat ignored under the dazzle of biological sciences. Main social theories are functionalism, interpersonal theory, attachment theory, stress theory, and labeling theory. Each of these theories had tried to explain the genesis of psychiatric disorders in their own way. However, each theory has its own limitations and critique. Still, for a holistic approach to treat persons with mental illness, it is essential to take a biopsychosocial approach which can only be done if one understands the contribution and relevance of social theories. Nonpharmacological management has been the cornerstone of treatment of any psychiatric disorder and social theories also form the basis of various nonpharmacological modes of treatment. Overall, social theories are still very relevant in current psychiatric practice and should not be neglected. Efforts should be made to integrate social theories with other theories of mental illness for better understanding and treatment
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
