The purpose of this study is to train an artificial neural network model for predicting student failure in the academic leveling course of the Escuela Politécnica Nacional of Ecuador, based on academic and socioeconomic information. For this, 1308 higher education students participated, 69.0% of whom failed the academic leveling course; besides, 93.7% of the students self-identified as mestizo, 83.9% came from the province of Pichincha, and 92.4% belonged to general population. As a first approximation, a neural network model was trained with twelve variables containing students' academic and socioeconomic information. Then, a dimensionality reduction process was performed from which a new neural network was modeled. This dimension reduced model was trained with the variables application score, vulnerability index, regime, gender, and population segment, which were the five variables that explained more than 80% of the first model. The classification accuracy of the dimension reduced model was 0.745, while precision and recall were 0.883 and 0.778, respectively. The area under ROC curve was 0.791. This model could be used as a guide to lead intervention policies so that the failure rate in the academic leveling course would decrease.Bullying is acknowledged by scientists as a considerable and still unresolved problem in sport. By triggering stress-related emotions, they determine the behavior of those experiencing bullying and cause various negative effects on their physical and mental health. However, in the presence of the tenacious trend in sports "to put one's own house in order," athletes, coaches, teams, and sports organizations themselves often do not emphasize bullying or state that they do not encounter the problem at all, and adheres to the belief that athletes may use negative emotions instrumentally in order to perform tasks given to them more effectively. The aim of this research was to reveal the determinants of the internal environment of sports organizations, causing trends of bullying in organized sport. To achieve the research aim, a qualitative research paradigm was chosen. The empirical study involved eight coaches working in organized sport in Lithuania. The survey was conducted using the semi-structured interview meroup leadership, existing in sport, and to predict how this may effect both the athlete himself, his environment and attractiveness of the sporting activity itself.Forensic inpatients (i. e., individuals found not responsible for a criminal offense on account of mental illness) represent an often marginalized and difficult-to-treat population. This has led to the need for research exploring the effectiveness of novel interventions. A Canadian forensic hospital has developed an 8-weeks mindfulness and yoga training program (MTP). This pilot study examined the potential effects of this program on patients' mindfulness, stress, and use of cognitive and emotion regulation strategies. A sample of 13 forensic inpatients (male = 92%) participating in the MTP program completed self-report measures assessing dispositional mindfulness, perceived stress, and use of cognitive emotion regulation strategies at baseline, post-intervention, and a 3-months follow-up. Repeated measure ANOVAs found a significant increase in the describe facet of mindfulness (p = 0.03) with a large effect size (ηp2 = 0.26) and a significant decrease in stress (p = 0.003) with a large effect size (ηp2 = 0.39). Pairwise comparisons revealed medium to large significant changes between baseline and post-intervention for both the describe facet (p = 0.03, Hedge's g = 0.55) and stress (p = 0.003, Hedge's g = 0.70). However, comparisons were insignificant between baseline and follow-up. No significant main effects were found on the use of cognitive emotion regulation strategies. This pilot study offers preliminary support for the use of the MTP as an adjunctive therapy in forensic inpatient treatment. Further investigation is needed into the long-term impacts of this training.The term "alexithymia" was introduced in the lexicon of psychiatry in the early '70s by Sifneos to outline the difficulties manifested by some patients in identifying and describing their own emotions. Since then, the construct has been broadened and partially modified. Today this describes a condition characterized by an altered emotional awareness which leads to difficulties in recognizing your own and others' emotions. In half a century, the volume of scientific products focusing on alexithymia has exceeded 5,000. Such an expansive knowledge domain poses a difficulty for those willing to understand how alexithymia research has developed. Scientometrics embodies a solution to this issue, employing computational, and visual analytic methods to uncover meaningful patterns within large bibliographical corpora. In this study, we used the CiteSpace software to examine a corpus of 4,930 publications on alexithymia ranging from 1980 to 2020 and their 100,251 references included in Web of Science.

Inhibition of peripheral 11-beta-hydroxysteroid-dehydrogenase type 2 (11betaHSD2) reverses these markers. We therefore tested the hypothesis that the 11betaHSD2 inhibitor glycyrrhizin affects treatment outcome via this mechanism. We administered Glycyrrhiza glabra (GG) extract containing 7-8 % of glycyrrhizin at a dose of 2 × 700 mg daily adjunct to standard antidepressants in hospitalized patients with major depression. These subjects were compared in an open-label fashion with patients, who did not receive GG (treatment as usual, TAU). Assessments were done at baseline and approximately 2 weeks after. Twelve subjects were treated with GG and compared to 55 subjects with TAU. At week 2, the Hamilton Depression Rating Scale (HAMD-21) change from baseline as well as the CGI-S change showed a significant time × treatment interaction (p less then 0.03), indicating a possible therapeutic benefit of GG. Autophagy agonist Clinical benefit seems to be more pronounced in subjects with lower systolic blood pressure and significantly correlated with reduced sleep duration in the GG group. Our preliminary data show that treatment with the 11betaHSD2 inhibitor glycyrrhizin may possess a beneficial effect on antidepressant response, which may be specific to a defined depression subtype.
