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
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
Common mental disorders among mothers of children under five Years of age attended treatment for severe acute malnutrition In jimma city, oromia, Ethiopia
No full textBackground: Common Mental Disorders (CMDs) are among the most prevalent forms of
mental disorders globally. Women are twice as likely as men to be diagnosed with CMDs,
and mothers are particularly prone to these disorders. CMD can have significant long-term
adverse impacts on both mothers and their children. Maternal physical illnesses are well
known to be associated with children severe acute malnutrition. The existing limited
evidences of CMD among mothers of children with severe acute malnutrition (SAM) are
conflicting. Therefore, this study aimed to assess the magnitude and associated factors of
maternal common mental disorders among these mothers.
Objectives: To determine the magnitude and associated factors of common mental disorders
among mothers of children under five years of age attended treatment for severe acute
malnutrition in Jimma city, Oromia, Ethiopia, 2025
Methods: An institution-based, cross-sectional study was conducted among 163 mothers of
children under five years of age who attended treatment for severe acute malnutrition at
Jimma University Medical Center (JUMC) and Shenen Gibe General Hospital from January
to March2025. Data was collected by trained nurses using structured questionnaire. CMD
was measured by World Health Organization Self-Reporting Questionnaire-20 (WHO SRQ
20). Structured questionnaires was used to measure factors associated with CMD. Data entry
and analysis were done by Statistical Package for Social Sciences (SPSS) version 26. A
bivariate and multivariable logistic regression analyses was performed. The strength of
association was measured by the adjusted odds ratio (AOR) with a 95% confidence interval
(CI), and a p-value of <0.05 was used to determine statistical significance. The final results
were presented in the form of tables, figures and texts
Results: The majority of mothers (60%) were aged 25–34 years and most were married
(80.4%).Over half (55.2%) were unable to read or write and nearly half (51.5%) were were
housewives. The majority of mothers was Muslim (81.6%) and lived in rural areas (82.2%).
Nearly half of the children (49.7%) were between the age of 12–36 months.The majority of
house holds experienced of mild food insecurity (45.4%) while only 13.5% being fully food
secure.
I
The prevalence of maternal common mental disorders was 31.9%. Mothers with co-morbid
medical illnesses (AOR = 3.5; 95% CI: 1.08–11.35), a history of mental illness (AOR = 4.24;
95% CI: 1.13–15.82), infants under 12 months (AOR = 6.81; 95% CI: 1.25–37.13), child
chronic illness (AOR = 4.03; 95% CI: 1.02–15.84), and short birth intervals (AOR = 3.81;
95% CI: 1.41–10.27) were significantly associated with mothers CMD. The absence of
intimate partner violence reduced CMD likelihood by 73.3% (AOR = 0.267; 95% CI: 0.08
0.93).
Conclusion and Recommendation: Nearly one third of participants reported common
mental illness. Mothers with co-morbid medical illnesses, previous history of mental illness,
having infants under 12 months, child chronic illness, and short birth intervals were
significantly associated with maternal CMD. Conversely, the absence of intimate partner
violence reduced CMD likelihood by two third. Therefore, integrating maternal CMDs
screening and psychosocial support into existing SAM treatment protocol is essential
quality of life and associated factors among patients with schizophrenia attending follow up treatment at jimma university medical center psychiatric clinic jimma, south west Ethiopia, 2018
No full textBackground: Schizophrenia is one of the most severe, chronic and disabling mental disorder
found globally. The chronic nature of the illnesses significantly interferes with functioning in
domains like physical, psychological, social and economic at last results in poor quality of life.
Objectives: To assess quality of life and associated factors of patients with schizophrenia
attending follow up treatment at Jimma University Medical Center psychiatric clinic, Jimma,
South West, Ethiopia, 2018.
Methods: A hospital based cross sectional study design was employed. Data was collected by
interviewer administered pre-tested semi structured questionnaire from 352study participants
who were selected by systematic random sampling technique. Quality of life was assessed by
using the world health organization quality of life assessment brief version and severity of
symptoms (psychopathology) and medication adherence was assessed by positive and negative
syndrome scale and Morisky medication adherence scale respectively. Data entry and analysis
was done using Epi data version 3.1 and SPSS 20 statistical software. Different assumptions of
linear regression model were checked. Linear regression analysis was performed to determine
an association between independent and dependent variables.
Result: A total of 351 patients with schizophrenia were participated in this study with 99.7 % of
response rate. The mean (± SD) age of the participant was 33.57 ± 7.96 years, and ranges from
18 to 54.The mean (± SD) score of the WHOQOL-BREF scale in this study was 74.34 ± 15.83.
Patients with schizophrenia had lowest mean score on the social relationship domain of
WHOQOL-BREF scale. Income (β: 5.81, 95% CI: 3.45-8.18) was found to be positively
associated with QOL. On contrary positive symptoms (β: -0.33, 95% CI: -0.49-(-0.17)), negative
symptoms (β: -0.26, 95% CI: -0.45-(-0.06)), general psychopathologies (β: -0.22, 95% CI: -0.32-
(-0.12)), comorbid physical illness (β: -4.69, 95% 95% CI: -8.50-(-0.88)), ever use of tobacco (β:
-3.95, 95% CI; -5.34-(-0.95)), ever use of Khat (β: -3.95, 95% CI; -6.02-(-1.88)) and medication
non-adherent(β: -5.81, 95% CI: -8.24-(-3.41))were found to be negatively associated with QOL.
Conclusion and recommendation: The domain of social relationship was the lowest domain of
quality of life for patients with schizophrenia. Therefore, in schizophrenic patients, priority
interventions to improve the social deficits are important
Prevalence of cluster b personality disorders and associated Factors among patients with mental illnesses attending Psychiatric outpatient treatment at jimma medical center, Jimma, southwest ethiopia, 2021
Full text linkBackground: Diagnosing co-occurring personality disorders, particularly cluster B
personality disorders the most comorbid one, in psychiatric patients is clinically important
because of their association with the duration, recurrence, and outcome of the comorbid
disorders.
Objective: To assess the prevalence of cluster B personality disorders and associated factors
among patients with mental illnesses attending psychiatric outpatient treatment at JMC,2021.
Methods: An institutional-based cross-sectional study was employed among 404 patients with
mental illnesses. A systematic random sampling method was utilized to select the patients from
Jimma medical center, psychiatry clinic, from July 15 to September 14, 2021. Personality
disorder questionnaire four (PDQ-4) was used to assess the prevalence of cluster B personality
disorders through a face-to-face interview. Data was entered into Epi Data Version 4.6 and
exported to SPSS Version 26 for analysis. Descriptive analysis was done using frequency,
percentage, mean and standard deviation. Logistic regression analysis was done and variables
with a p-value less than 0.05 with 95% confidence interval in the final fitting model were
declared as independent predictors of cluster B personality disorders.
Result: Among 401 respondents with response rate of 99.3%, slightly less than one-fourth
(23.19%, N=93) were found to have cluster B personality disorders, from which (8.7%, N=35)
were borderline, (7.2%, N=29) antisocial, (6.5%, N=26) narcissistic, and (3.2%, N=13)
histrionic personality disorder. Diagnosis of depressive (AOR=3.33, 95%CI=1.59–6.97)) and
bipolar-I disorders (AOR=2.76, 95%CI=1.16–6.56)), longer duration of illness (AOR=2.22,
95%CI=1.24–3.98)), multiple relapses (AOR=2.21, 95%CI=1.18–4.15)), history of family
mental illnesses (AOR=2.33, 95%CI=1.26–4.30)), recent cannabis use (AOR =5.73,
95%CI=2.16–15.24)), starting to use substance at earlier age (AOR=4.77, 95%CI=1.71–
13.33),suicidal attempt (AOR=3.17, 95%CI=1.39–7.26), emotional abuse(AOR=2.85,
95%CI=1.44–5.63), and interpersonal functioning impairments (AOR=3.74, 95%CI=1.99–
7.02) were the factors significantly associated with cluster B personality disorders.
Conclusion: The prevalence of cluster B personality disorders was high among mentally ill
outpatients and it is found to be important for mental health professionals working on the
outpatient departments to screen for cluster B PD as part of their routine activities. Having
diagnosis of mood disorders, longer duration of illness, multiple relapses, history of family
mental illnesses, recent cannabis use, starting to use substance at earlier age, suicidal attempt,
emotional abuse, and interpersonal functioning impairments were significantly associated with
cluster B personality disorder
