Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
COMPARING SYMPTOMS OF KALACHI SLEEPING SYNDROME WITH KNOWN DISEASES AND CONDITIONS TO DETERMINE CLASSIFICATION OF CAUSAL AGENT. INCIDENCE DENSITY SAMPLING CALCULATIONS
Introduction. In 2011some of the residents of Kalachi were afflicted with a sudden acute syndrome,
where they would abruptly fall into an immediate abnormal sleep. These episodes of losing consciousness
could happen anywhere and anytime. By the end of 2015, news reports estimated than 1out of
every 4 residents had developed this syndrome. Both children and adults were afflicted. Males and females
were equally affected with no gender preference. The overall purpose of the study is to characterize
signs and symptoms of the sleeping syndrome to confirm or reject the likely classification of causal
agents, based on the various hypotheses. Those include viruses, fungi, bacteria, chemicals, radiation,
mass sociogenic illness, and gases such as carbon monoxide and carbon dioxide intoxications. Second
purpose will be to assess the risks of developing the syndrome 1st,2nd and 3rd times through incidence
density sampling calculations.
Methods: Analyses on comparisons and contrasts with signs and symptoms and frequencies of signs
and symptoms of the Kalachi sleeping syndrome with those produced by various potential causal agents,
as reported in the published scientific literature. The statistical package SPSS was utilized for data management
and statistical applications. Analyses on the risks (overall hazard) of developing disease the first
time versus the second or third time, to determine if the sleeping syndrome conveyed any “immunity”,
utilized a probabilistic theoretical method sometimes utilized in survival analysis related to time to episode,
called incidence density sampling.
Results: Among the leading reported symptoms were spinning head, headache followed by fatique and
memory loss, significantly less number of people reported fever. The probability of getting 1st episode
equals to 0.2014 and 2nd episode equals to 0.3314. There is a statistically significant high chances to get
2nd episode if one already had a previous case (p=0.005). Finally, for the 3rd episode equals to 0.2615.
Conclusion: Symptomatically and in line with the previous household investigation current hypothesis
of incapacitant water transmission seems reasonable. Infectious nature of the cause is less likely due to
absence of immunity after the first exposure as it is evidenced from density sampling calculations
Dispelling the Myths Behind First-author Citation Counts
We 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
Undergraduate students’ knowledge, attitude and perceptions of infertility, infertility risks and treatment within universities in Astana, Kazakhstan.
Infertility is a global issue that affects millions (Sami,2006). According to the World Bank, the fertility rate has declining trend in Kazakhstan. Infertility does not have only medical consequences, it also leads to psychosocial and economic issues, thus has public health importance (Rouchou, 2013). Social consequences of infertility consist of stigma, marital instability, social health risks and domestic violence (Rouchou, 2013). This types of social aspects of infertility were detrimental in setting psychological issues in infertile people. The psychological problems included depression, anxiety and identity predicaments (Hasanpoor-Azghdy, 2014). Fertility has immense importance for infertile people. But infertility treatment is costly, thus can bring a financial burden to those who cannot afford it (White, 2005; Boivin, 2007). Knowledge of infertility risks and its treatment options can help to decrease the incidence of infertility by educating youth
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
