What can Google Trends and Wikipedia-Pageview analysis tell us about the landscape of epilepsy surgery over time?
No full textBACKGROUND: Epilepsy surgery is an effective treatment for drug-resistant epilepsy. Some centers have noticed changes in referral patterns. AIM: The aim of this study was to determine if online infodemiological data related to epilepsy surgery reflect reported changes in referrals to surgical centers. METHODS: Google Trends and Pageview analysis of temporal trends of searches conducted in Google and Wikipedia for epilepsy surgery, using key search terms such as "epilepsy surgery" and terms related to pathology, operation type, and investigative practice. RESULTS: Over the 15-year time period studied by Google trend analysis, when the initial three-year epoch and final three-year epoch are compared, a 56.1% decline in search volume for "epilepsy surgery" was observed. Vagus nerve stimulation and laser ablation are increasingly searched items. Pageview analysis shows that temporal lobe epilepsy remains the most commonly searched subtype of epilepsy and hippocampal sclerosis was searched for more than focal cortical dysplasia. CONCLUSION: This study suggests a lower search interest over time in epilepsy surgery, and various associated terms, with increased interest in vagus nerve stimulation and laser ablation procedures over time. There is no clear indication from these data regarding the apparent shift from mesial temporal cases to an increase in extratemporal case workload
Readability of online sources of information regarding epilepsy surgery and its impact on decision-making processes
No full textIntroductionPeople with epilepsy can have cognitive deficits, including difficulty with reading tasks. This can potentially impact on how written information is understood. Websites increasingly provide information about different medical interventions including epilepsy surgery. Our aim was to assess the readability of a sample of one hundred patient-oriented educational English language websites related to epilepsy surgery.MethodsA Google search was carried out using the terms epilepsy and surgery, and a sample of forty-nine websites from both the UK and the US were chosen. These websites were uploaded to a freely available online readability scoring tool (readabilityformulas.com) and seven measures of readability generated were examined. Other data including use of figures/diagrams, patient narratives, and mention of the risks/benefits of surgery were noted.ResultsThe majority of the websites analyzed in this study were found to be ‘difficult’ to read for the average reading level of the population (n = 1-impossible, 10-very difficult, 23-difficult, 14 fairly difficult). Only 1 website was considered suitable for average reading level. The use of infographics was variable – some webpages used them extensively to reiterate the textual information and other websites did not.Discussion and conclusionThe available online patient information literature is likely to be too difficult for the average reader to understand. It is important that websites are accessible, reliable, and aid understanding related to epilepsy surgery, taking potential cognitive deficits into consideration
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
Online behavior of people visiting a scientific website on epilepsy
No full textWe investigated the online behavior of Internet users consulting the website of the Italian Chapter of the International League Against Epilepsy (Lega Italiana Contro l'Epilessia [LICE]). We obtained the visualization statistics of the LICE website using AWStats (https://awstats.sourceforge.io/) and Google Trends (https://trends.google.com/trends/), and compared the statistics of years 2010, 2014, and 2017. The following variables were analyzed: number of unique visitors and visits, visit duration, the day of week and rush hours, most downloaded documents, most viewed pages, keyphrases and keywords used for online searches, origins of searches, and geographic trends of Google searches related to the LICE. The total numbers of unique visitors, visits and page views remained quite stable over time. Most visits (70 to 76.7%) lasted less than 30 s. The most frequent keyphrases and keywords used for online searches were related to clinical guidelines and driving license. Among the most frequently downloaded documents were general guides on epilepsy. The pages with the list of epilepsy centers endorsed by the LICE and those with the list of LICE guidelines were among those most frequently viewed, together with educational videos. Most users directly accessed the website without being referred from external links. No information on geographic origin of Google searches was available. The visualization statistics suggested two distinct populations of visitors. The first one is likely represented by physicians who seek specialist information on diagnosis and management of epilepsy, including guidelines. The second population is represented by lay people who seek accessible and easily comprehensible information to better understand epilepsy and know which centers are best for its management

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
