Genes involved in Alzheimer's disease, a survey of possible candidates.
No full textAlzheimer's disease (AD) is the major cause of dementia in the elderly. It is
characterized by a progressive deterioration in memory and cognitive functions, but also
behavioral symptoms are common. Many different genes are possibly involved in
Alzheimer's Disease: four genetic factors were confirmed in different studies, while at
least 50 additional genes were tested with contrasting results. A major aim both for
clinician and researchers would be the identification of the genes involved in AD, to
better understand the biological mechanism of this disease and consequently to develop
appropriate treatments. The aim of this review is to explore genetics of AD
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
PERSONALITY DISORDERS FEATURES IN A SAMPLE OF WOMEN WITH PERINATAL DEPRESSION IN PERUGIA, ITALY
No full textBackground: Antepartum depression (APD) and postpartum depression (PPD) are a significant public health problem. Aim of the study was to determine which personality disorders features could be found in women with APD and PPD compared to women without perinatal depression. Subjects and methods: The Edinburgh Postnatal Depression Scale and the Minnesota Multiphasic Personality Inventory-2 (MMPI- 2) were administered during peripartum to a sample of 54 women recruited at the Obstetrics and Gynaecology Unit, Perugia (Italy). Results: Results were grouped according to the EPDS ranges 0-8 and >9, and to the MMPI-2 scores on each clinical scale. Women with APD had high scores on the MMPI-2 Hypomania, Cynicism, and Antisocial Practices scales; women with early onset PPD (detected in the first week after childbirth) had high scores on the Paranoia and Low Self-Esteem scales; women with late onset PPD (detected up to three months after childbirth), had high scores on the Fears, Obsessiveness, and Depression scales. Conclusions: Based on the high scores of specific MMPI-2 scales, our study would suggest that: Cluster B personality features may represent a vulnerability factor for APD; passive-aggressive personality features may be a vulnerability factor for early onset PPD; cluster C personality features may act as a vulnerability factor for late onset PPD
