Age, dyslexia subtype and comorbidity modulate rapid auditory processing in developmental dyslexia

The nature of Rapid Auditory Processing (RAP) deficits in dyslexia remains debated, together with the specificity of the problem to certain types of stimuli and/or restricted subgroups of individuals. Following the hypothesis that the heterogeneity of the dyslexic population may have led to contrasting results, the aim of the study was to define the effect of age, dyslexia subtype and comorbidity on the discrimination and reproduction of nonverbal tone sequences.Participants were 46 children aged 8 - 14 (26 with dyslexia, subdivided according to age, presence of a previous language delay, and type of dyslexia). Experimental tasks were a Temporal Order Judgment (TOJ) (manipulating tone length, ISI and sequence length), and a Pattern Discrimination Task. Dyslexic children showed general RAP deficits. Tone length and ISI influenced dyslexic and control children’s performance in a similar way, but dyslexic children were more affected by an increase from 2 to 5 sounds. As to age, older dyslexic children’s difficulty in reproducing sequences of 4 and 5 tones was similar to that of normally reading younger (but not older) children. In the analysis of subgroup profiles, the crucial variable appears to be the advantage, or lack thereof, in processing long vs short sounds. Dyslexic children with a previous language delay obtained the lowest scores in RAP measures, but they performed worse with shorter stimuli, similar to control children, while dyslexic-only children showed no advantage for longer stimuli. As to dyslexia subtype, only surface dyslexics improved their performance with longer stimuli, while phonological dyslexics did not. Differential scores for short vs long tones and for long vs short ISIs predict nonword and word reading, respectively, and the former correlate with phonemic awareness.In conclusion, the relationship between nonverbal RAP, phonemic skills and reading abilities appears to be characterized by complex interactions with subgroup characteristics

Trying to keep in touch with Nature during the COVID-19 pandemic: an experience from the University of Trento

[EN] Italy was one of the Western countries more seriously affected by the COVID-19 pandemic. To counter the outbreak, government resorted to different types of precautionary measures and restrictions. Education, at all levels, from nursery school to university, also suffered the repercussions of the pandemic, with the halt of classroom attendance and the move to distance learning. At the University of Trento, where I teach Ecology, the second semester of the 2019–2020 academic year took place entirely via online teaching, while in the following academic year it was possible to resort to a blended modality. The paper illustrates the initiatives I used to facilitate interaction between students and to set up a mutual dialogue between students and teacher, with the aim of creating a sense of community and of bringing students, isolated and shut up in their homes, into contact with the natural environment.Cantiani, M.

Accuracy of elastic fusion biopsy in daily practice: results of a multicenter study of 2115 patients

OBJECTIVES: To assess the accuracy of Koelis fusion biopsy for the detection of prostate cancer and clinically significant prostate cancer in the everyday practice. METHODS: We retrospectively enrolled 2115 patients from 15 institutions in four European countries undergoing transrectal Koelis fusion biopsy from 2010 to 2017. A variable number of target (usually 2-4) and random cores (usually 10-14) were carried out, depending on the clinical case and institution habits. The overall and clinically significant prostate cancer detection rates were assessed, evaluating the diagnostic role of additional random biopsies. The cancer detection rate was correlated to multiparametric magnetic resonance imaging features and clinical variables. RESULTS: The mean number of targeted and random cores taken were 3.9 (standard deviation 2.1) and 10.5 (standard deviation 5.0), respectively. The cancer detection rate of Koelis biopsies was 58% for all cancers and 43% for clinically significant prostate cancer. The performance of additional, random cores improved the cancer detection rate of 13% for all cancers (P < 0.001) and 9% for clinically significant prostate cancer (P < 0.001). Prostate cancer was detected in 31%, 66% and 89% of patients with lesions scored as Prostate Imaging Reporting and Data System 3, 4 and 5, respectively. Clinical stage and Prostate Imaging Reporting and Data System score were predictors of prostate cancer detection in multivariate analyses. Prostate-specific antigen was associated with prostate cancer detection only for clinically significant prostate cancer. CONCLUSIONS: Koelis fusion biopsy offers a good cancer detection rate, which is increased in patients with a high Prostate Imaging Reporting and Data System score and clinical stage. The performance of additional, random cores seems unavoidable for correct sampling. In our experience, the Prostate Imaging Reporting and Data System score and clinical stage are predictors of prostate cancer and clinically significant prostate cancer detection; prostate-specific antigen is associated only with clinically significant prostate cancer detection, and a higher number of biopsy cores are not associated with a higher cancer detection rate

Assessing the mechanical stability of trees in artificial plantations of Pinus nigra J. F. Arnold using the LWN tool under different site indexes

In young black pine plantations, the most valuable and interesting thinning scheme is mainly based on the positive selection of dominant and well-shaped trees to be candidates for carbon sequestration, timber production and natural regeneration. The mechanical stability of candidate trees is here a fundamental skill that must be taken into account and the slenderness ratio (HD) is one of the main indicators. HD has been recently proved to be correlated to the living whorl number (LWN) by Cantiani & Chiavetta (2015). In this study, the statistical model was re-calibrated in order to study the influence of soil fertility on the HD - Living whorls number (LWN) relationship.The fertility-balanced models estimated a different LWN threshold. The model for the highest fertility class (Site index 24) estimated 12 LWN (RMSE of 20%). Similarly, a lower value were detected for the other two fertility classes, SI20 and SI16, where 10 LWN were considered enough with an associated RMSE of 16% and 17% respectively. Compared to the general model provided by Cantiani & Chiavetta (11 LWN with 18% of RMSE) the site index approach improved the accuracy and reliability

How to Teach Ecology to Students of Environmental Engineering

[EN] The paper illustrates a set of teaching practices applied by the author in the course of Ecology, addressed to third year students of the First Cycle Degree (BSc) in Environmental and Land Engineering, at the University of Trento (Italy). The features of the university context and the main characteristics of these students are described, also referring to changes which have occurred over time. On the basis of a twenty-five-year teaching experience, the author highlights the challenges and opportunities of an approach aimed at involving students in the learning process, raising interest and curiosity towards ecological issues, stimulating students’ emotional competencies and their capacity to critically reflect on their own educational experience. In conclusion some comments are made regarding the need for a greater engagement by the academic staff towards non-conventional teaching and learning experiences. In particular, a more integrated method of evaluation of the quality of teaching is sought, effective in taking into account different approaches and techiniques and comparing learning outcomes.Cantiani, M.
