El sueño roto de la ciudadanía europea y el lado oscuro de la gobernanza
2015
Este trabajo trata de analizar tres modelos de ciudadanía europea a partir de la crisis de legitimidad del modelo de gobernanza europeo a la que asistimos hoy. Presentaré los rasgos de esta crisis del modelo de gobernanza, aclarando cómo esta crisis pone de manifiesto 1) el poder de veto de algunos de los estados miembros 2) la falta de responsabilidad de las decisiones comunitarias hacia las opiniones públicas 3) la reducción de confianza mutua de los actores políticos y económicos. Mostraré como los tres modelos, respectivamente el modelo nacional- liberal, el modelo de la ciudadanía de mercado y el modelo federal, ofrecen diversas respuestas a la pregunta acerca del significado del ideal…
The effect of individual and classroom moral disengagement on antisocial behaviors in Colombian adolescents: A multilevel model
2022
The present study examined the predictive effect of moral disengagement (within and between classrooms) on antisocial behaviors in Colombian adolescents, as well as the interaction of moral disengagement with classroom composition by age, socioeconomic status (SES), and perceived teacher–student relationship quality. Multilevel modeling was used to identify individual, compositional, and contextual effects on antisocial behaviors. The predictive variables were: (a) classroom mean score (i.e., between-classroom analysis), and (b) student deviation from the classroom mean score (i.e., within-classroom analysis). The sample included 879 students nested in 24 seventh-grade classrooms in three C…
Modelling students' mobility in Italy: an analysis of the determinants by combining individual and aggregated data
The migratory phenomenon consisting in the enrolment of some students in a University different from the one nearest to their place of origin goes under the name of students’ mobility (SM). This phenomenon can be studied for different territorial aggregations, depending on the aims and the availability of data. In Italy several analyses have been carried out to detect the determinants of such a phenomenon. Two approaches are mostly followed. The former considers the analysis of aggregate data (AD) flows, and it is aimed at detecting the characteristics of the Universities and the territories in which they are situated, the latter analyzes the determinants of SM on the grounds of the student…
Resident’s Perceptions of Tourism Influence on Quality of Life: a Multilevel approach.
2015
This study aims to evaluate whether individual perceptions of tourism’s effects on quality of life (TQOL) are related to the degree of tourism activity in the host community, as well as to residents’ personal characteristics, by a multilevel model. Data from a survey performed in Sicily have been analyzed. The model revealed that the level of tourism activity have an influence on the way residents perceive the effect tourism in their community, as measured by TOQL index.
La legge sul sindacato militare: se vogliamo che tutto rimanga come è, bisogna che tutto cambi
2023
Il saggio analizza la recente legge sul sindacato militare a seguito della sentenza della Corte costituzionale 120/2018, che ha dichiarato l’incostituzionalità del divieto di costituire associazioni sindacali nelle Forze armate e di polizia a ordinamento militare. Alla luce dell’ordinamento multilivello (costituzione, convenzioni Oil, Carta Sociale e Cedu) l’articolo sottolinea l’irragionevole compressione legislativa della libertà sindacale a favore della coesione interna dell’apparato militare. Il filo rosso dei vari divieti e restrizioni risiede nella persistente adesione della politica agli obsoleti modelli teorici degli ordinamenti interni e dei rapporti di supremazia speciale, che non…
Building up adjusted indicators of students' evaluation of university courses using generalized item response models
2012
This article advances a proposal for building up adjusted composite indicators of the quality of university courses from students’ assessments. The flexible framework of Generalized Item Response Models is adopted here for controlling the sources of heterogeneity in the data structure that make evaluations across courses not directly comparable. Specifically, it allows us to: jointly model students’ ratings to the set of items which define the quality of university courses; explicitly consider the dimensionality of the items composing the evaluation form; evaluate and remove the effect of potential confounding factors which may affect students’ evaluation; model the intra-cluster variabilit…
Switching Frequency Effects on the Efficiency and Harmonic Distortion in a Three-Phase Five-Level CHBMI Prototype with Multicarrier PWM Schemes: Expe…
2022
The current climatic scenario requires the use of innovative solutions to increase the production of electricity from renewable energy sources. Multilevel Power Inverters are a promising solution to improve the penetration of renewable energy sources into the electrical grid. Moreover, the performance of MPIs is a function of the modulation strategy employed and of its features (modulation index and switching frequency). This paper presents an extended and experimental analysis of three-phase five-level Cascaded H-Bridges Multilevel Inverter performance in terms of efficiency and harmonic content considering several MC PWM modulation strategies. In detail, the CHBMI performance is analyzed …
Tutela e sicurezza del lavoro tra centro e periferia: la sicurezza sui luoghi di lavoro
2013
Il saggio prende in esame la complessa questione del riparto di competenze tra Stato e Regioni alla luce del Titolo V della Costituzione in materia di salute e sicurezza sui luoghi di lavoro. Il riparto di competenze tra centro e periferia è stato oggetto di una limitata analisi da parte della dottrina e della giurisprudenza, che si sono concentrate in particolare sulla disciplina del mercato del lavoro. L’Autore descrive un sistema multilivello, caratterizzato dalla compresenza di fonti nazionali e regionali, della contrattazione collettiva, nonché di codici di condotta. Sulla scorta di una ricostruzione del quadro normativo e dei percorsi della giurisprudenza, il saggio propone una lettur…
The alliance-outcome association in group interventions: A multilevel meta-analysis.
2022
Objective: The therapeutic alliance has been studied in group interventions, but its relationship to patient outcome is still controversial. This study systematically reviewed the association of both the member-leader and member-group alliance with patient outcomes, and assessed the effects of several theoretically informed moderators. Method: A three-level meta-analysis was conducted on 57 studies to disentangle within- and between-study variability in the alliance-outcome association. Results: The overall effect size of the unconditional model was r = -.259 (95% CI: -.302, -.214; p < .001), whereas the correlation between alliance and outcome based on the three-level meta-analytic mode…
Implementation on NI-SOM sbRIO-9651 and Experimental Validation of Multi-Carrier PWM Techniques for Three-Phase Five Level Cascaded H-Bridge Inverter
2021
Multilevel Power Inverters (MPIs) represent a valid solution to improve the performances of energy production systems from renewable energy sources. Furthermore, the use of novel FPGA control systems allows simplifying the implementation of multicarrier PWM techniques for MPIs with computational benefits. This paper describes the implementation of several multicarrier PWM techniques on NI-SOM sbRIO-9651 for the control of a three-phase five-level cascaded H-bridge inverter. In detail, sbRIO-9651 is a control system in the field of Power Electronics and Drives (PED) programmable in the LabVIEW graphical programming environment. The paper is focused on modulation techniques implementation, te…
