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
The role of metformin hydrochloride in complex therapy of disorders of carbohydrate metabolism in patients with paranoid schizophrenia treated with atypical antipsychotics
Get PDFIntroduction. According to the literature, mortality among patients with schizophrenia is 1.5 -2 times higher than in the healthy population. One explanation for this is the complication of neuroleptic therapy, which, according to various authors, occurs in 2 to 100% of cases.
Purpose. We aimed to study some indicators of carbohydrate metabolism disorders in patients with paranoid schizophrenia who have been taking neuroleptics for a long time, to correct the established changes by adding metformin hydrochloride to the standard regimen and to monitor its effectiveness.
Methodology. The study was conducted based on Municipal non-commercial enterprise "Precarpathian regional clinical center of mental health of Ivano-Frankivsk regional council. This study included patients diagnosed with paranoid schizophrenia according to the criteria of ICD-10 (F20.0). As a result of our studies in 63 patients, we found a violation of carbohydrate metabolism, which accounted for 52% of all examined. Among them, 55 patients with prediabetes: 12 (19.04%) patients with impaired glucose tolerance (IGT), 43 (68%) with impaired fasting glycemia (IFG), and 8 patients (12.7%) with type 2 diabetes mellitus (T2D). Subsequently, all these 63 patients were prescribed corrective therapy with a drug from the group of biguanides - metformin hydrochloride at a dose from 500 to 1000 mg/day: in violation of IFG at a dose of 500 mg/day; in case of IGT - 850 mg/day; in the case of T2D- 1000 mg/day. All studies were performed before and after 3 months of metformin correction. These included fasting glucose, postprandial hyperglycemia (PPG) (two hours after a meal), glycosylated hemoglobin (HbAIc), immunoreactive insulin (IRI), and, if necessary, an oral glucose tolerance test (OGTT). Fasting plasma glucose (FPG) was measured by the glucose oxidase method. HbAIc values were determined by ion-exchange high-performance liquid chromatography (HPLC). The determination of the IRI level was performed by enzyme-linked immunosorbent assay (ELISA)
Results and Discussion. The results of the research showed that 52% of all surveyed found disorders of carbohydrate metabolism. They were prescribed corrective therapy with a drug from the group of biguanides - metformin hydrochloride at a dose of 500 to 1000 mg/day. As a result of the research, we found that in all groups of examined patients revealed a positive dynamics of carbohydrate metabolism under the influence of this drug. A significantly higher therapeutic effect of the treatment of carbohydrate metabolism disorders with metformin was found in patients receiving the latter in combination with haloperidol. The combination of metformin with risperidone and quetiapine showed a slightly lower clinical effect.
Conclusion. Our own clinical experience gives grounds to recommend metformin hydrochloride as a medium for the correction of carbohydrate metabolism disorders in patients with a paranoid form of schizophrenia in the treatment of this category of patients with neuroleptic
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
The nature of the manifestation of procrastination, level of anxiety and depression in medical students in a period of altered psycho-emotional state during forced social distancing because of pandemic COVID-19 and its impact on academic performance
Get PDFIntroduction: The fact that learning is moving online is probably a disappointment to most medical students. This is especially true for middle and senior students, in whom most disciplines are clinical and focus on practical work with patients. During the period of forced social distancing and online learning in connection with the COVID-19 pandemic, such a common way of learning became impossible. All these changes obviously affect the mental health of medical students, who are already at risk for such phenomenon as procrastination and disorders as anxiety and depression.
Purpose: Investigate and evaluate the level of anxiety, depression, and the nature of the manifestation of procrastination in medical students Faculty of Medicine and the Faculty of Training Foreign Citizens (FTFC) of Ivano-Frankivsk National Medical University (IFNMU) in a period of altered psycho-emotional state during the period of forced social distancing and its impact on academic performance.
Methodology: 212 medical students were interviewed. The survey was voluntary and anonymous. We used two clinical test methods to identify emotional disturbances: the Hospital Anxiety and Depression Scale (HADS) and the Montgomery-Asberg Depression Rating Scale (MADRS) (Zigmond A.S. et.al.,1983; Svanborg P., 2001). In order to assess the propensity of students to procrastinate, we also used the "Questionnaire to study the propensity of the individual to procrastination" (Shivari ,O.A., 2015), which is a modification of the "General Procrastination Scale" (Lay, C., 1986) and consists of two scales: "Personally conditioned procrastination scale" (Scale I) and "Situationally conditioned procrastination scale" (Scale II). The statistical analysis of the results was performed using STATISTICA 7.0 software packages and the package of statistical functions of Microsoft Excel.
Results and Discussion: During the testing, students note that the most important problem for them is time management. The analysis of the results survey by "Personally conditioned procrastination scale" (Scale I) "showed that 15% of the students have a low, 47.5% - medium, 37.5% - high level of personal propensity to procrastination. The analysis of the results "Situationally conditioned procrastination scale" (Scale II) showed that 25% of students have a low level of situational procrastination, 37.5% - medium and 37.5% - high, respectively. The study of the relationship between the level of propensity to procrastination (Scale I) and academic performance in medical students showed that in the group with low procrastination the success rate is higher than in groups with medium and high procrastination (r = -0.58; p <0.05). We also established a direct correlation between the Scale II indicators and the average academic performance indicators. After the survey and analysis of the results on the HADS and MADRS scales, we found a clear relationship between increased learning during the period of altered psychoemotional state and the severity of anxiety-depressive symptoms in medical students, which manifested itself in an increase in the level of anxiety and mood disorders of varying degrees.
Conclusions: Thus, procrastination that occurs in the surveyed medical students in the period of altered psycho-emotional state during forced social distancing because of pandemic COVID-19 has had "situational" situational nature. Besides, the study confirmed that the pandemic of COVID-19, as a stressful moment of the external test of identity, caused the emergence of protective mechanisms in medical students in the form of emotional and behavioral changes and disorders. The results obtained indicate the presence of adjustment disorders in the period of the altered psychoemotional state during forced social distancing because of pandemic COVID-19 in all the studied groups. Medical students also need to be made aware that depression is not a cause for shame. Future doctors should be able to maintain their mental and emotional health, as well as know, how to deal with classmates who suffer from mental illnes
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
