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 →...

Paper About Plagiarism Contains Plagiarism

by Neuroskeptic in Neuroskeptic_Discover

Regular readers will know that I have an interest in plagiarism. Today I discovered an amusing case of plagiarism in a paper about plagiarism.

The paper is called The confounding factors leading to plagiarism in academic writing and some suggested remedies. It recently appeared in the Journal of the Pakistan Medical Association (JPMA) and it's written by two Saudi Arabia-based authors, Salman Yousuf Guraya and Shaista Salman Guraya.

Fatal Attraction: Praying Mantises (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

By Britta Bibbo We all know the character: an incredibly beautiful woman that seduces the rough-and-tumble action hero, only for him to later find himself chained up over a lava pit with sharks in it! …Or something like that. A “femme fatal” is the idea of a beautiful woman who leads men to their demise. None are more perfect for this role than the female praying mantis. Praying mantis females practice the art of deception through sexual cannibalism. It’s exactly how it sounds: the m........ 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 ref........ 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 ........ Read more »

The Landscape of Neuroscience 2006 - 2015

by Neuroskeptic in Neuroskeptic_Discover

How has neuroscience changed over the past decade? In a new paper, Hong Kong researchers Andy Wai Kan Yeung and colleagues take a look at brain science using the tools of citation analysis.



Yeung et al. extracted data from 2006-2015 from Web of Science and Journal Citation Reports (JCR), which track publications and citations. All journals that the JCR classifies in the "Neurosciences" category were included.

The first change Yeung et al. noticed was that the number of published neuros... Read more »

Outsourcing and precariousness of work in the social assistance policy

by SciELO in SciELO in Perspective | Press Releases

This paper presents the work conditions of psychologists hired by private organizations to work at the Sistema único de Assistência Social (Unified System for Social Assistance). Among other things, it concludes that this “outsourcing” process has been allowing temporary contracts, high turnover rates, late payment of salaries, dismissal of large groups of employees and lack of continuing education, which impacts the health of the workers and the quality of the services offered. … Re........
