Subjective stress, objective heart rate variability-based stress, and recovery on workdays among overweight and psychologically distressed individual…
2015
Background: The present study aimed to investigate how subjective self-reported stress is associated with objective heart rate variability (HRV)-based stress and recovery on workdays. Another aim was to investigate how physical activity (PA), body composition, and age are associated with subjective stress, objective stress, and recovery. Methods: Working-age participants (n = 221; 185 women, 36 men) in this cross-sectional study were overweight (body mass index, 25.3-40.1 kg/m(2)) and psychologically distressed (>= 3/12 points on the General Health Questionnaire). Objective stress and recovery were based on HRV recordings over 1-3 workdays. Subjective stress was assessed by the Perceived St…
School-related bullying : analysis of bullying preventive programs and analysis of power from perspective of social philosophy
2017
The present thesis is dedicated to a problem of school-related bullying. Bullying is a global problem that affect big number of students, and has serious short- and long-term consequences. Bullying can be manifested in various forms: it can be physical, emotional, and lately also cyber-bullying. Being a complex phenomenon, bullying can be difficult to identify, to intervene or prevent. It originates from power imbalance in a social group, and can target anyone who qualifies as “different” in any way. In order to provide analysis of bullying, in the present paper are presented definitions and analysis of the phenomenon of bullying as well global statistics of bullying across the countries in…

Alleviating Class Imbalance Problem in Automatic Sleep Stage Classification
2022
For real-world automatic sleep-stage classification tasks, various existing deep learning-based models are biased toward the majority with a high proportion. Because of the unique sleep structure, most of the current polysomnography (PSG) datasets suffer an inherent class imbalance problem (CIP), in which the number of each sleep stage is severely unequal. In this study, we first define the class imbalance factor (CIF) to describe the level of CIP quantitatively. Afterward, we propose two balancing methods to alleviate this problem from the dataset quantity and the relationship between the class distribution and the applied model, respectively. The first one is to employ the data augmentati…
Au revoir Paris! Spanish regions closer to the EU average and further away from the leaders
2021
This paper confirms that Spanish regions in 2015 were closer to the EU average in labour productivity than in 2000, but further away from the richest regions such as Île de France. A dynamic shift-share analysis at a 10-industry level of disaggregation shows that the main driver of convergence with the EU average is catch-up in labour productivity within the same industry, while disparities with the top regions (especially Île de France) mainly involve differences in patterns of specialization (between-industry divergence) followed by technological divergence (within-industry effect). The industry mix of the regions reveals that a new pattern of specialization is taking shape in Europe, dri…
Functional Basis of Asymmetrical Lower-Body Skeletal Morphology in Professional Australian Rules Footballers
2020
Hart, NH, Newton, RU, Weber, J, Spiteri, T, Rantalainen, T, Dobbin, M, Chivers, P, and Nimphius, S. Functional basis of asymmetrical lower-body skeletal morphology in elite Australian footballers. J Strength Cond Res 34(3): 791–799, 2020—Bone strength is a product of its material and structural properties and is highly responsive to mechanical load. Given the measureable and adaptable features of bone, and thus relevance to medical screening, injury prevention, and injury management in athletes, this study describes the lower-body skeletal morphology of professional Australian rules footballers. Using a cross-sectional and quantitative study design, 54 professional Australian rules football…
Інновації в управлінні фіскальним вирівнюванням: реформа децентралізації
2020
Стаття присвячена обгрунтуванню доцільності запровадження інноваційних підходів до підвищення ефективності системи фінансового вирівнювання та оперативного управління фінансовими дисбалансами територій в умовах реалізації реформи децентралізації. Проведене дослідження узагальнює результати наукового аналізу дієвості системи горизонтального фінансового вирівнювання як інструменту зменшення міжтериторіальних економічних та соціальних диспропорцій. Предметом дослідження є процеси управління системою фінансового вирівнювання в Україні в період з 2015 року, оскільки саме в цей час розпочалася реформа децентралізації, основою якої є перерозподіл фінансових ресурсів. Наявність низки невирішених пр…
