Study suggests computational model to predict air pollution after a rocket launching

by SciELO in SciELO in Perspective | Press Releases

The study suggests a new approach to predict major atmospheric pollutants emissions after a Satellite Launch Vehicle (SLV) launching, using a weather/air quality computational model. Propellant combustion may release a huge amount of hydrogen chloride (HCl), carbon monoxide (CO), carbon dioxide (CO2) and particulate matter, posing risk to the environment. … Read More →...

Gender disparities in science persist despite significant advances

by SciELO in SciELO in Perspective

The participation of women as authors in academic publications has been increasing significantly worldwide and in all areas of knowledge, reaching 49% in Brazil and Portugal, followed by Australia (44%) and the European Union (41%). Gender equity in science, however, still has a long way to go, especially in the editing and peer review functions. A study of more than 41,000 articles published between 2007 and 2015 shows that male editors - who are majority - preferentially select same gender referees. … Read More →... Read more »

Openness is the only quality of an academic article that can be objectively measured

by SciELO in SciELO in Perspective

Quality of scientific research articles is a widespread preoccupation in academic circles. The most used proxy is based on citation counts, not of the article itself, but of the averages of articles appearing in the same journal during a given time window. This is known as the Journal Impact Factor, which may be objective within its own definition, but utterly lacks objectivity with regard to scientific quality of individual articles. Only some technical qualities of articles can be assessed at the time of their publication, and, significantly, their openness, the degree to which the research results they describe can be immediately and universally shared. … Read More →...

Are we in the GSM Radar?

by SciELO in SciELO in Perspective

Google Scholar Metrics (GSM) offers alternative metrics to the JCR Impact Factor and the SJR, namely the h-5 index. To enter this world ranking that covers more than 40,000 journals it is only necessary to publish an average of 20 articles per year and be cited. However, there are hundreds of journals (our journals) that are not being indexed in GSM. They're off Radar. … Read More →... Read more »

I wrote this… I did not write this… now I write something else…

by SciELO in SciELO in Perspective

The emerging system of online scholarly communication incorporates a technological and ideologically approach different from the traditional one, where the articles initially appear as preprints versions and are modified until reaching the final version. In case of errors, these same technologies provide efficient opportunities to make partial or total corrections and even retractions, associating to the path of a document the history of its versions. It is time, therefore, to establish methodologies that allow to obtain the maximum of more updated information to support the scientific undertakings. … Read More →... Read more »

Opioids, Benzos and Risk for Overdose

by William Yates, M.D. in Brain Posts

The evolving epidemic of opioid overdose and overdose deaths is receiving increased public and research attention.Opioids overdoses and overdose deaths are often unintentional or accidental. It has been known that concurrent use of opioids with alcohol or benzodiazepines (i.e. Valium or Xanax) increases risk for overdose toxicity.A recent study published in the British Medical Journal confirmed the association of concurrent benzodiazepine prescription with opioid overdose.This research team examined confidential medical database records from over 500,000 patients in the U.S.Those that were enrolled in a medical plan including pharmaceutical benefits between 2001 and 2013 were included in the analysis.The key findings from the study included the following:The percentage of opioid users concurrently using a benzodiazepine rose from 9% of opioid users in 2001 to 17% of opioid users in 2013Chronic users of opioids nearly doubled their risk of opioid overdose if they took a concurrent benzodiazepine medication (4/100 persons/year to 7-8/100 person years)If the association is causal, the authors estimate emergency room visits and inpatient admissions could be reduced by 15% by stopping concurrent prescriptionsThis association of risk seems reasonable given the toxicities of opioids and benzodiazepines. Both at higher doses decrease respiratory drive potentially contributing to hypoxia and death.The authors note several take home messages for clinicians. Chronic users of benzodiazepines should be prescribed opioids cautiously if at all. Opioid prescriptions should be for short periods of time and low doses for chronic benzodiazepine patients.Likewise, if chronic opioids are necessary they should rarely be combined with intermittent or long-term benzodiazepine prescriptions.Readers with more interest in this topic can access the free full-text manuscript by clicking on the PMID link in the citation below.Photo of NCAA men's basketball tournament in Tulsa, OK is from my files.Follow me on Twitter WRY999Sun EC, Dixit A, Humphreys K, Darnall BD, Baker LC, & Mackey S (2017).

Internationalization as an indicator of journal performance in Brazil: the case of Psychology

by SciELO in SciELO in Perspective

The path to strengthening scientific publications almost always goes through internationalization. Publishing in English, however, is not enough to reach a truly global audience and indices comparable to the most prestigious journals. A study on the degree of internationalization of Brazilian psychology journals shows how to walk this path. … Read More →... Read more »

Politics Trump Healthcare Information: News Coverage of the Affordable Care Act

by Jalees Rehman in The Next Regeneration

Gollust and colleagues found that 55% of the news stories either focused on the politics of the ACA such as political disagreements over its implementation (26.5%) or combined information regarding its politics with information on how it would affect healthcare insurance options (28.6%). Only 45% of the news stories focused exclusively on the healthcare insurance options provided by the law. The politics-focused news stories were also more likely to refer to the law as “Obamacare” whereas healthcare insurance focused news segments used the official name “Affordable Care Act” or “ACA”. Surprisingly, the expansion of Medicaid, which was one of the cornerstones of the ACA because it would increase the potential access to health insurance for millions of Americans, was often ignored. Only 7.4% of news stories mentioned Medicaid at all, and only 5% had a Medicaid focus.

Scientific reliability and the role of theory

by Multiple Authors in EPPI-Centre blog

The replication crisis, publication bias, p-hacking, harking, bad incentives, undesirable pressures and probably other factors all contribute to diminish the trustworthiness of published research, with obvious implications for research synthesis. Sergio Graziosi asks whether demanding simple theoretical clarity might be part of the solution.

Biofouling successional processes

by SciELO in SciELO in Perspective | Press Releases

To assess the successional pattern of fouling organisms we tested the hypothesis that depth, light intensity and predation influences the trajectory of the fouling community. The results suggest that each physical factor or biological process can change the successional trajectory, and the respective model (e.g., convergent, divergent, parallel, or cyclic) depends on the magnitudes of the determinants that act on the community at each stage of its trajectory. … Read More →...
