Studies about subterranean fauna in Latin America were intensified in the last decades. Many research are species description, but other knowledge areas have been studied, such as subterranean invertebrates communities. This study aims to characterize studies about these communities in Latin America countries. We made a bibliographic survey of published papers in scientific journals and bulletins of speleology groups, and different aspects were verified, like localities (country), publish date, number of sampled caves, use of tests and statistical analyzes and sample effort. Of the 20 Latin America countries, we not found those studies for ten (10) of them (Bolivia, Costa Rica, El Salvador, Haiti, Honduras, Nicaragua, Panama, Paraguay, Dominican Republic, and Uruguay). We accessed a total of 164 published studies, of which the most was conducted in Brazil (69), followed by Mexico (52), Venezuela (17) and Cuba (11). In Brazil, most of studies was published in the last two decades (2000-2017), in Mexico in the 70’s, in Venezuela between 80’s and 2009 and in Cuba in 70’s and 90’s. Except for Brazil, where the most of studies explored the influence of biotic and abiotic factors in the communities, all countries published mainly faunistic inventories about only an unique cave or region. Thus, they do not present tests and statistical analysis and, sometimes, neither ecological discussion. Moreover, many publications do not have information about number of sample occasions and most of Brazilian studies did only one sample occasion. That makes it harder both the ecological approach that permits the verification of patterns that acts in the communities structuring and the comparison of data from different regions. Therefore, although the knowledge of subterranean invertebrates communities has increased, the Latin American has a huge potential to be explored in relation to areas with few or no studies, and to more consistent ecological studies.

This article presents part of a larger study on the use of reference sources to perform bibliographical search by graduate students in Education. Data relating to the use of the scientific journals by these students are presented and discussed. Sixty Education graduate students, 28 Master degree and 32 Doctoral, answered an electronic questionnaire. The students indicated the types of articles usually read and the importance attributed to each one. For each of treated themes in the electronic questionnaire, data are initially presented and analyzed in the set of the 60 participants of the study and then compared between master and doctoral students. Were used the Chi-squared (?2) test, the Fisher exact test and the Spearman’s correlation coefficient. Research reports were more frequently pointed out but less valued in comparison to articles referring to critical review and theoretical essay. Methodological articles, appearing in fourth position according to reading frequency and importance attributed, are more valued by doctoral than master students. The students read these articles using different procedures. The possible reasons for the students valorizing the articles of critical review and theoretical essays are discussed. The present study intends to offer a contribution to understand the use of scientific information by students, describing some graduate students’ habits related to information seeking in scientific journals, and reading of the articles published.

The way science is done has changed radically in the last years. The personal reflections and experiences of a protagonist help us to understand the mechanisms of contemporary science. A system where passion, dedication and reliability, have increasingly less room, pressed by hard market laws. From vocation of a few, science has become the profession of many, possibly too many. With consequences and risks, such as the increase of frauds, plagiarism, but in particular with a huge amount of scientific publications, often of little relevance. The solution? A slow approach with more emphasis to quality than quantity, that helps us to rediscover the central role of a responsible scientist. The work is a critical review and assessment of present-day policies and behaviors in science production and publication, touching upon the tumultuous growth of scientific Journals, in parallel to the growth of self-declared scientists over the world. Along with personal reminiscences of times past, the author investigates the loopholes and hoaxes of pretended Journals and non-existing Congresses, so common nowadays in the scientific arena. The troubles with bibliometric indices are also discussed, as resulting in large part from the above distortions of science life.

This paper presents the first critical review of literature on poverty published in Russia between 1992 and 2006. Using a dataset of about 250 publications in Russian scientific journals we assess whether the poverty research in Russia satisfies the general criteria of a scientific publication and if such studies could provide reliable guidance to the Russian government as it maps out its anti-poverty policies. Our findings indicate that only a small portion of papers on poverty published in Russia in 1992-2006 follow the universally-recognized principles of the scientific method. The utility of policy advice based on such research is questionable. We also suggest certain steps that could, in our view, improve the quality of poverty research in Russia.

A review of the most significant domestic and, due to numerical superiority, foreign works on physical modelling of snow transport and snow accumulation processes, in particular, for the purpose of determining snow loads on roofs with arbitrary geometry, is presented. The existing practice of development of recommendations on assignment of snow loads in Russian laboratories is considered and critically evaluated. Comparison of do-mesticworks with scientific articles in the advanced world scientific journals and foreign regulatory documents leads to unfavorable conclusions. Recommendations on assigning snow loads, issued by Russian laboratories on the basisof extremely outdated and poorly substantiated methodology, bear a serious risk for evaluating mechan-ical safety of modern structures, for which such recommendations are developed. Recommendations are offered to remedy this current dangerous practice. The article also gives some suggestions on forming a basis for field observations of snow loads on existing roofs.

IntroductionMental trauma may precede persistent changes in a person's mental health in the form of psychosis and dissociation. Presently, there are no subtypes to the diagnosis of PTSD. A psychotic subtype of PTSD has been proposed, and studies show that these patients differ as well in symptoms as biologically from patients with non-psychotic PTSD. Dissociation and psychosis are generally viewed as different phenomena. Where dissociation is understood as a disintegration of the mind, psychosis is viewed as a neurodegenerative disorder on a mainly biological/genetic basis. The delineation of psychotic and dissociative symptoms is not clear however.ObjectivesOur objective is to clarify, whether psychologists and psychiatrists describe trauma-related changes of consciousness (TCC) differently as dissociative or psychotic. Furthermore, we wish to compare scientific journals, and look for differences in how psychiatrists’ and psychologists’ make use of the terms dissociation and psychosis in relation to TCC.AimsWe aim to investigate whether TCC are interpreted differently among psychiatrists and psychologists.MethodsThis study is a systematic critical review of the literature. The databases PubMed, Embase and PsychInfo will be used. Articles involving PTSD with TCC will be included. Studies will be classified as viewing TCC's as either psychotic or dissociative, based on the terms the authors use to describe the observed phenomena.ResultsThe results will be presented at the EPA in March 2016 in Madrid.ConclusionThe study will reveal differences in how psychiatrists and psychologists classify TCC's in PTSD.Disclosure of interestThe authors have not supplied their declaration of competing interest.
