Self-Esteem, Socially Prescribed Perfectionism, and Parental Burnout
2022
AbstractSocially prescribed perfectionism (SPP) has been shown to be a risk factor for parental burnout (Sorkkila & Aunola, 2020). In the present study, we investigated the moderating role of self-esteem in this association. A total of 479 Finnish mothers of infants filled in questionnaires measuring their self-esteem, SPP, and symptoms of parental burnout. The results of structural equation modelling (SEM) showed that mothers’ self-esteem moderated the effect of SPP on parental burnout: Mothers with high self-esteem were at lower risk of showing burnout symptoms even when SPP co-occurred, whereas for mothers with low self-esteem, the effect of SPP on burnout symptoms was further streng…
Is individual- and school-level teacher burnout reduced by proactive strategies?
2021
There is provisional evidence that burnout may be contagious within professional communities via the crossover effect, referring to an inter-individual transmission of stress or strain. However, our understanding of effective means for tackling stressors is scarce. We tested a two-level path model to explore the interrelation between teachers’ proactive self- and co-regulative strategies and experienced burnout. The study sample comprised 1531 Finnish in-service teachers from 75 schools. The results showed that burnout symptoms varied both between individual teachers and between professional communities. Self- and co-regulative strategies serve partly different functions in regulating teach…
Dietetica e politica: regimi di senso.
2021
Usually when we use the word "diet" in contemporary culture, the first thing that comes to mind is the slimming diet. And, with it, everything in the collective imagination: calories, reducing quantities, giving up quantities, giving up the tastiest foods, and also instructions, manuals periodic checks, scales and so on. But the word 'diet' comes from the ancient Greek dìaita meaning 'way of life', 'daily habits'. What is meant by diet, then, can also be extended in reference to today: not only, in the strict sense, a programme to lose weight but a way of life, a way of regulating one's day, food choices, physical exercise, body care. This is how we will consider it: in the sense of regime …
Giudici amministratori
2023
Spesso funzioni amministrative sono svolte da giudici. La separazione dei poteri è un criterio ordinatore dell’ordinamento costituzionale che, tuttavia, non è osservato nel diritto positivo in modo assoluto. Questa sovrapposizione tra funzioni e poteri può considerarsi fisiologica rispetto ad una realtà ordinamentale complessa. Viceversa, l’osservazione fenomenologica evidenzia situazioni diverse nelle quali la tracimazione del potere giurisdizionale in quello amministrativo diviene problematica. Il presente contributo, attraverso lo studio di tre casi concreti, si propone di individuare le ragioni e le implicazioni tendenziali di questa tracimazione. La debolezza strutturale dell’amministr…

Time domain symmetry parameters analysis for series arc fault detection
2022
This paper presents a feasibility study of exploiting the symmetry of some parameters for series arc fault detection in electrical circuits. The considered parameters are defined in the time domain and they are based on the current signal derivative and the evaluation of cross-correlation between subsequent observation windows. The analysis is carried out for AC systems, starting from an experimental characterization, which has been carried out in accordance with the Standard UL 1699 requirements for "unwanted tripping tests"and "operation inhibition tests"of arc fault circuit interrupters (AFCIs). The results obtained in different load conditions show that the proposed parameters can be us…
Performance Improvement of Grid-Integrated Doubly Fed Induction Generator under Asymmetrical and Symmetrical Faults
2023
The doubly fed induction generator (DFIG)-based wind energy conversion system (WECS) suffers from voltage and frequency fluctuations due to the stochastic nature of wind speed as well as nonlinear loads. Moreover, the high penetration of wind energy into the power grid is a challenge for its smooth operation. Hence, symmetrical faults are most intense, inflicting the stator winding to low voltage, disturbing the low-voltage ride-through (LVRT) functionality of a DFIG. The vector control strategy with proportional–integral (PI) controllers was used to control rotor-side converter (RSC) and grid-side converter (GSC) parameters. During a symmetrical fault, however, a series grid-side converter…
