Improving the Reliability of Literature Reviews: Detection of Retracted Articles through Academic Search Engines.

Nowadays, a multitude of scientific publications on health science are being developed that require correct bibliographic search in order to avoid the use and inclusion of retracted literature in them. The use of these articles could directly affect the consistency of the scientific studies and could affect clinical practice. The aim of the present study was to evaluate the capacity of the main scientific literature search engines, both general (Gooogle Scholar) and scientific (PubMed, EMBASE, SCOPUS, and Web of Science), used in health sciences in order to check their ability to detect and warn users of retracted articles in the searches carried out. The sample of retracted articles was obtained from RetractionWatch. The results showed that although Google Scholar was the search engine with the highest capacity to retrieve selected articles, it was the least effective, compared with scientific search engines, at providing information on the retraction of articles. The use of different scientific search engines to retrieve as many scientific articles as possible, as well as never using only a generic search engine, is highly recommended. This will reduce the possibility of including retracted articles and will avoid affecting the reliability of the scientific studies carried out.

Antivaccine Movement and COVID-19 Negationism: A Content Analysis of Spanish-Written Messages on Twitter.

During the COVID-19 pandemic, different conspiracies have risen, with the most dangerous being those focusing on vaccines. Today, there exists a social media movement focused on destroying the credibility of vaccines and trying to convince people to ignore the advice of governments and health organizations on vaccination. Our aim was to analyze a COVID-19 antivaccination message campaign on Twitter that uses Spanish as the main language, to find the key elements in their communication strategy. Twitter data were retrieved from 14 to 28 December using NodeXL software. We analyzed tweets in Spanish, focusing on influential users, most influential tweets, and content analysis of tweets. The results revealed ordinary citizens who 'offer the truth' as the most important profile in this network. The content analysis showed antivaccine tweets (31.05%) as the most frequent. The analysis of anti-COVID19 tweets showed that attacks against vaccine safety were the most important (79.87%) but we detected a new kind of message presenting the vaccine as a means of manipulating the human genetic code (8.1%). We concluded that the antivaccine movement and its tenets have great influence in the COVID-19 negationist movement. We observed a new topic in COVID-19 vaccine hoaxes that must be considered in our fight against misinformation.

Gestores de referencias como herramientas del día a día. Zotero / Reference managers as day-to-day tools. Zotero

Los gestores de referencias son herramientas surgidas en los años ochenta para facilitar la labor de citación y referencia en los textos académicos. Con los años, han aparecido nuevos gestores que incluyen nuevas funcionalidades, como localizar referencias en Internet, su descarga y almacenamiento, gestión, adición de información de cada referencia, e incluso algunos van más allá y facilitan la visibilidad y comunicación entre los investigadores. En este artículo nos centramos en los gestores de carácter gratuito, más concretamente en Zotero, explicando sus características, instalación y uso, y se hace una breve comparación con Mendeley. Los gestores de referencias son herramientas muy útiles e indispensables hoy en día que ahorran mucho tiempo y preocupaciones a cualquier persona que necesite presentar un trabajo académico o publicar un artículo

Reference managers are tools that appeared in the 1980s to facilitate the work of citation and reference in academic texts. Over the years, new reference managers have appeared that include new functionalities, such as locating references on the internet, downloading and storing them, managing and adding information to each reference, and some even go beyond this and facilitate visibility and communication among researchers. In this article we focus on free managers, more specifically Zotero, explaining their characteristics, installation and use, and making a brief comparison with Mendeley. Reference managers are very useful and indispensable tools today that save a lot of time and worries for anyone who needs to present an academic paper or publish an article

La epidemia de las revistas depredadoras / The predatory journals epidemy

La proliferación de las llamadas revistas depredadoras y su desconocimiento por parte de los investigadores son un peligro para la integridad científica. Es una necesidad y deber de los autores conocer y saber detectar este tipo de revistas para no publicar en ellas, pero también para no basar sus investigaciones en los trabajos que publican, y que no han pasado un proceso crítico de calidad apoyado en la revisión por pares. Se introduce el concepto de revista depredadora, algunos de sus elementos diferenciadores y los peligros que entrañan para la ciencia en general y los investigadores en particular

The proliferation of so-called predatory journals and their ignorance by researchers are a danger to scientific integrity. Authors need and must know them and therefore know how to detect these types of journals so as not to publish in them, but also so as not to base their research on the work they publish, which has not undergone a critical quality process supported by peer review. This text introduces the concept of a predatory journal, some of its differentiating elements and the dangers they entail for science in general and the researcher in particular
