Computer-assisted evaluation and treatment of depression in cystic fibrosis patients
No full textCystic fibrosis (CF) is a widespread chronic multisystem disease that profoundly impairs physical and mental health, with anxiety and depression being on the forefront of CF-associated problems. This study intends to explore alpha EEG patterns as main indicators of relaxation/anxiety, and to investigate prospective of neurofeedback treatment for depression in CF patients.
The EEG data were obtained from 13 CF and 10 healthy subjects, in two sessions using BOSLAB equipment and additionally analyzed with WINEEG software. Between measurements, an alpha increasing neurofeedback session was applied. Values of Alpha Peak Frequency (APF) were compared with the standard personality assessment. Final statistical evaluation was performed with Statistica 5. Significant difference (t = -3,154, p< 0.05) for APF between experimental (mean 9.07 Hz) and control group (mean 10.33 Hz) was found in the initial EEG assessment. In addition, APF increased after just one alpha neurofeedback session in both groups (in CF patients, t = -5,226, p< 0.05). The psychological assessment in patients with cystic fibrosis revealed neurotic profile, while the score for depression was below the cutoff for its manifestation.
These findings indicate that computer-assisted evaluation can support the process of successful estimation and treatment of depression in CF patients. However, being a pioneering study in this field, further investigations are recommended
Characteristics of electroencephalographic alpha rhythm parameters in cystic fibrosis patients: Perspectives of neurofeedback
No full textPurpose: The aim of this study was to investigate electroencephalographic (EEG) alpha parameters that are specific for cystic fibrosis (CF) patients and to focus on the perspectives of neurofeedback training in CF individuals. Methods: The data were obtained from experimental (13 CF patients) and control group (10 healthy students) in two sessions using BOSLAB neurofeedback equipment and additionally analyzed with WINEEG software program. Between the sessions, an alpha increasing neurofeedback session was applied. Individual Alpha Peak Frequency (IAPF) and Individual Alpha Bandwidth (IABW) were investigated. Standard personality assessment and statistical tests (Statistica 5) were used for final evaluation. Results: Significant difference (t = 3,154, p < 0.05) for IAPF between experimental (mean 9.07 Hz) and control group (mean 10.33 Hz) was measured in the initial EEG assessment. In addition, IAPF increased after one alpha neurofeedback session in both groups (in CF patients, t = 5,226, p < 0.05). The psychological assessment in adolescents with cystic fibrosis revealed neurotic profile, while the score for depression was below cut-off for manifested depression. Conclusion: These findings indicate the negative psycho-emotional impact of CF. Neurofeedback can be successfully used to support CF patient’s capacity for self-management. Further investigations are needed for confirmation of these results
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
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
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
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
