ADHD symptoms and maladaptive achievement strategies: the reciprocal prediction of academic performance beyond the transition to middle school

2023

This longitudinal study examined how two externalising behaviour problems, attention-deficit hyperactivity disorder (ADHD) and conduct disorder (CDs), are associated over time with low motivation (MAS), and how these problems effect academic performance. In our cross-lagged analysis, we found reciprocal effects between ADHD symptoms and MAS between Grades 5 and 6. Both domains also negatively predicted later academic performance. With CDs and MAS, no cross-lagged effects were found, although both were correlated and very stable over time, and negatively predicted later academic performance. These different kinds of externalising problem behaviours seem to differ in the way in which they int…

Changes in nocturnal heart rate variability and endurance performance during a high-intensity or high-volume endurance training period in recreationa…

2014

It is known that endurance training affects the modulation of the autonomic nervous system and heart rate variability (HRV). As a method HRV may be a potential tool to monitor trainability and endurance training adaptation. The purpose of this study was to examine changes in nocturnal HRV indices and endurance running performance during high intensity versus high volume endurance training. In total, 28 recreational male and female endurance runners (35 ± 8 year, VO2max 50 ± 5 ml/kg/min) were matched into two training groups after the 8 week basic training period (BTP) according to HRV, endurance performance and training adaptation during BTP. During the 8 week hard training period (HTP), th…

Monitoring Training and Recovery during a Period of Increased Intensity or Volume in Recreational Endurance Athletes

2021

The purpose of the study was to examine the effects of progressively increased training intensity or volume on the nocturnal heart rate (HR) and heart rate variability (HRV), countermovement jump, perceived recovery, and heart rate-running speed index (HR-RS index). Another aim was to analyze how observed patterns during the training period in these monitoring variables were associated with the changes in endurance performance. Thirty recreationally trained participants performed a 10-week control period of regular training and a 10-week training period of either increased training intensity (INT, n = 13) or volume (VOL, n = 17). Changes in endurance performance were assessed by an incremen…

A DISSECTION'S GUIDE TO HUMAN ABDOMINAL CAVITY

2020

The purpose of this article is to show the abdominal cavity's dissection method. In the summer of 2018 a group of students from the University of Palermo, who had already taken the anatomy exam and had good knowledege of English, went for a period of two weeks to do a dissection course at the University of malta. The students dissected skin, subcutaneously, muscle layers, parietal peritoneum and abdominal organs. this works proves to be a small dissection guide for young medical students who want to learn the main bases of dissection and important information for topographical anatomy.

A BRIEF ANATOMO-SURGICAL DISSECTION GUIDE TO HUMAN LOWER LIMB: RESULTS OF THE COLLABORATION BETWEEN THE UNIVERSITY OF PALERMO AND THE UNIVERSITY OF M…

2020

The aim of this Article is to show methods for dissection of the lower limb. In the summer 2017 a group of students at the University of Palermo that have already passed the exam of Human Anatomy took a 4 weeks dissection course at the University of Malta - School of Medicine. The students were provided with a dissection kit, video recording equipment and cameras for taking pictures. This paper presents the results of the dissection course and a small and simple guide to young students and medical doctors who want to learn the bases of lower limb dissection.

Predicting and monitoring individual endurance training adaptation and individualizing training prescription : with endurance performance, cardiac au…

2016

Humans adapt differently to standardized endurance training programs. While some individuals may achieve huge improvements in physical fitness, other individuals may even suffer from negative adaptations. Special attention should be paid to identification of non-responders, which would enable to modify training to be more effective. Therefore, the aim of the present study was to investigate whether running performance, cardiac autonomic regulation and neuromuscular performance can be used in 1) predicting subsequent endurance training adaptations; 2) monitoring training adaptations; and 3) individualizing training prescription in recreational endurance runners. Three longitudinal training s…

Towards Robust Adaptive Least-Squares Parameter Estimation with Internal Feedback

1998

Abstract The new concepts of the ‘covariance matrix normalization’ and the ‘cascade’ structure of the adaptive least-squares estimator are shown to generalize and extend the use of internal information feedback in various robustness/alertness-oriented modifications to the standard ALS estimation algorithm. In the cascade estimation structure it is possible to ‘naturally’ stabilize, rather than maximize, the information matrix so that the covariance windup and blowup are effectively eliminated and the celebrated square root update of the covariance matrix is no longer needed Consequently, a new, ‘single-loop/cascade’ ALS MIMO estimation algorithm, enabling to effectively track both slow and …

Structure and Photocatalytic Properties of TiO2-WO3Composites Prepared by Electrophoretic Deposition

2015

In this work TiO2-WO3 composite films containing different oxide concentrations were prepared by electrophoretic deposition on steel substrates. Composite coating structures were analyzed by X -ray diffraction, Raman spectra and scanning electron microscopy. The results showed an even distribution of WO3 particles in the entire composite layer. Light absorption measurements were used for photocatalytic properties evaluation. It was found that the removal ratio of methylene blue depends on the (TiO2):(WO3) concentration ratio. The most effective photodegradation was determined for the sample that was electrophoretically deposited from the suspension with the molar content ratio n(TiO2):n(WO3…
