Student teachers’ perceptions and evidence of peer learning through co-teaching: improving attitudes and willingness towards co-teaching

European Journal of Psychology of Education - Despite the increasing practice and evidence of its potential, co-teaching has not become a widespread practice in schools yet. Research shows the need...     

Potential adverse cardiac remodelling in highly trained athletes: still unknown clinical significance

Moderate endurance exercise has long been considered an essential element to maintain cardiovascular health, and sedentary behaviour in the general population has been related to a significant increase in all-causes of mortality, cardiovascular disease mortality and cardiovascular disease incidence. However, a growing group of people performs an intense exercise that leads to multiple heart adaptive changes that are collectively called “athlete’s heart”. In this review, we discussed the evidence of cardiac remodelling process secondary to repetitive and strenuous exercise in some predisposed athletes that produces intense and probably deleterious changes in cardiac morphology and function with no clear clinical significance in long-term follow-up. Moreover, we also discussed the individual biological response to exercise assessed by myocardial damage, inflammation, oxidative stress, fibrosis and ventricular hypertrophy biomarkers showing different intensities with equivalent exertion.     

Happiness,Life Satisfaction,Resiliency and Social Support in Students with Dyslexia

Many people with dyslexia experience numerous failures in their lifetime. This can reduce their life satisfaction and the sense of happiness. However, external support and one’s personal resources, for example resiliency, aid in dealing with difficult situations. Our study verified the importance of resiliency and perceived social support for the level of life satisfaction and the sense of happiness in Polish students with and without dyslexia, studying at both state and non-state universities. We used the Cantril Self-Anchoring Scale, SHI-PL Questionnaire, Resiliency Scale, and Social Support Questionnaire. The results showed that students with dyslexia demonstrated lower levels of: life satisfaction, positive emotions, resiliency, perceived/expected emotional and practical support, and general social support. The difference in happiness remained at the level of a statistical trend. Therefore, we conclude that dyslexia may be treated a risk factor in terms of happiness and life satisfaction in young adults.     

Participation in health through the construction of encounters: a micropolitical approach

We assume that the construction of encounters that produce care is a participative practice in health. Drawing on different research that has explored care production from a micropolitical approach, we present a view of participation as embedded in everyday life and based on the construction of encounters and relationships. Our goal is to provide reflections for debate on participatory practice within different frames of action. Based on the analysis of different cartographic narratives generated by research on a reproductive health policy, we discuss some core elements for the construction of encounters that produce care. On the same lines as models of professional development based on professionals’ day-to-day experiences, we propose experimentation during the encounters and discussion about what happens in them, as both a reflective practices and forms of collective and participative knowledge production.     

Quantification of mercury in XVIII century books by Energy Dispersive X-Ray Fluorescence (EDXRF)

This work describes the quantitative analysis of mercury present in the ink used to colour some books of XVIII century. The mercury content was determined by Energy Dispersive X-ray Spectrometry. This is a non-destructive technique which allows elemental identification and quantification (Z > 13) by atomic physics processes. The organic pigments cannot be identified by this technique, taking into account that its composition is mainly C, O and H. Levels of 2 wt.% and 4.5 wt.% were measured in 1756 and 1753 books respectively. No significant amount of mercury was observed in other red books, on a total of 11, all from XVIII century: 1720, 1732, 1753, 1756, 1780, 1798, 1800. More than one book for each year were analysed. The studied books belong to a private collection, and were selected taking into account the age and the reddish colour of their external parts. High content on Fe were observed in some of the books. This work highlights the application of a physics technique in a very important aspect for art and cultural heritage conservation and restoration, considering that high levels of toxic elements might be found in ancient documents. It is of great importance that preliminary elemental analyses are performed on ancient documents before handling them, because they might constitute some danger for restorers, conservators and collectors. This work highlights, for the first time, the danger of some ancient books. They might contain a very high concentration of mercury, which is toxic for the organism. This is also a particularly important problem of public health never mentioned in literature before.     

Comparison of diagnostic accuracy for eight SARS-CoV-2 serological assays

IntroductionSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) serological tests have been suggested as an additional diagnostic tool in highly suspected cases with a negative molecular test and determination of seroprevalence in population. We compared the diagnostic performance of eight commercial serological assays for IgA, IgM, and IgG antibodies to the SARS-CoV-2 virus.Materials and methodsThe comparison study was performed on a total of 76 serum samples: 30 SARS-CoV-2 polymerase chain reaction (PCR)-negative and 46 SARS-CoV-2 PCR-positive patients with asymptomatic to severe disease and symptoms duration from 3-30 days. The study included: three rapid lateral flow immunochromatographic assays (LFIC), two enzyme-linked immunosorbent assays (ELISA), and three chemiluminescence immunoassays (CLIA).ResultsAgreement between IgM assays were minimal to moderate (kappa 0.26 to 0.63) and for IgG moderate to excellent (kappa 0.72 to 0.92). Sensitivities improved with > 10 days of symptoms and were: 30% to 89% for IgM; 89% to 100% for IgG; 96% for IgA; 100% for IgA/IgM combination; 96% for total antibodies. Overall specificities were: 90% to 100% for IgM; 85% to 100% for IgG; 90% for IgA; 70% for IgA/IgM combination; 100% for total antibodies. Diagnostic accuracy for IgG ELISA and CIA assays were excellent (AUC ≥ 0.90), without significant difference. IgA showed significantly better diagnostic accuracy than IgM (P < 0.001).ConclusionThere is high variability between IgM assays independently of the assay format, while IgG assays showed moderate to perfect agreement. The appropriate time for testing is crucial for the proper immunity investigation.     

The Millennials: How and Why They Are Using Public Libraries. Reporting from Kyrgyzstan,the United States and Italy

Abstract

The Millennial Generation, sometimes referred to as Gen X—those young men and women born between 1981 and 1996—are the first generation of “digital natives.” This column reports on how their use of technology has changed public library services in Kyrgyzstan, the United States and Italy.
