The Cross-Level Moderation Effect of Resource-Providing Leadership on the Demands—Work Ability Relationship

2021

Employees in female-dominated sectors are exposed to high workloads, emotional job demands, and role ambiguity, and often have insufficient resources to deal with these demands. This imbalance causes strain, threatening employees’ work ability. The aim of this study was to examine whether resource-providing leadership at the workplace level buffers against the negative repercussions of these job demands on work ability. Employees (N = 2383) from 290 work groups across three countries (Germany, Finland, and Sweden) in female-dominated sectors were asked to complete questionnaires in this study. Employees rated their immediate supervisor’s resource-providing leadership and also self-reported …

The objective of the present research was to investigate associations of dispositional and momentary self-control and the presence of other individuals consuming SSBs with the consumption frequency of sugar-sweetened beverages (SSBs) in a multi-country pilot study. We conducted an Ambulatory Assessment in which 75 university students (52 females) from four study sites carried smartphones and received prompts six times a day in their everyday environments to capture information regarding momentary self-control and the presence of other individuals consuming SSBs. Multilevel models revealed a statistically significant negative association between dispositional self-control and SSB consumption…

Consumption Patterns and Family Life-Cycle. Some Evidence from Italy

2015

As a social and economic entity the family is changing continuously. Changes in family size and composition have significant effects on the family decision making process. The Italian context is an interesting subject for research as a result of the impact of demographic and economic changes in the early 2000s on new family structures and economic behaviour. Furthermore, in Italy in contrast to the past, both men and women are aiming for job security and satisfaction before marrying and starting a family. In the light of that, it is particularly interesting to investigate if consumption behaviour changes along the life cycle stages. Considering different family life stages enables us to exp…

Experimental study on B-spline-based modulation schemes applied in multilevel inverters for electric drive applications

2019

This work presents the design, simulation, and experimental validation of new B-Spline-based modulation techniques applied to a Multilevel Power Inverter (MPI), particularly focusing the attention on the harmonic content of the output voltages of the inverter. Simulation and experimental results are proposed and discussed, mainly describing the potential benefits, such as the increase of the multi-level operation of the converter, and drawbacks (low-order harmonics) related to the adoption of B-Spline functions for multilevel inverters applied in the field of electrical drives.

Experimental Investigation on the Performances of a Multilevel Inverter Using a Field Programmable Gate Array-Based Control System

2019

The Field Programmable Gate Array (FPGA) represents a valid solution for the design of control systems for inverters adopted in many industry applications, because of both its high flexibility of use and its high-performance with respect to other types of digital controllers. In this context, this paper presents an experimental investigation on the harmonic content of the voltages produced by a three-phase, five level cascaded H-Bridge Multilevel inverter with an FPGA-based control board, aiming also to evaluate the performance of the FPGA through the implementation of the main common modulation techniques and the comparison between simulation and experimental results. The control algorithm…

Testing for convergence from the micro-level

2011

Empirical convergence analysis is typically envisaged from a macro aggregate perspective. However, researchers have recently highlighted how investigating convergence at the disaggregate level may yield interesting insights into the convergence debate. In this paper, we suggest an approach that allows exploiting large micro panels to test for convergence. Compared to the traditional convergence analysis, this approach allows obtaining beta- and sigma-like convergence parameters for both the micro and the macro level of interest. We provide a practical example that analyses productivity convergence across firms and provinces using a large sample of Italian firms.

Coopetition Strategy and Entrepreneurial Opportunities: Advantages from Multilevel Analyses

2018

The study aims to provide a set of insights concerning the benefits associated with applying a multilevel perspective to the investigation of the link between coopetition strategies and entrepreneurial opportunities. We emphasize that a firm capability to recognize, form, and exploit business opportunities is strictly connected to its coopetitive strategy. In order to fully understand the potential of coopetitive strategies, the focus has to be not just on the examination of the single coopetitive relationship, but also on the micro-foundations underlying such strategies: i.e. the role covered by entrepreneurs’ or CEOs’ personal traits, heuristics, and previous experiences. We also suggest …

Contextual and local determinants associated with the achievement of goals in the endodontics specialty in Brazilian dental speciality centres: A mul…

2021

To assess which factors were associated with the achievement of endodontic goals.Cross-sectional study using secondary data from the second cycle of the Program for the Improvement of Access and Quality in the dental speciality centres-in Portuguese PMAQ-CEO. The independent variables extracted from this database were related to dental speciality centres (CEO in Portuguese). In addition, variables referring to the CEO host city were incorporated into the model. The outcome variable was the number of endodontic goals achieved calculated from the production of the CEO available in the Ambulatory Health Information System in 2018. Descriptive analyses and multilevel Poisson regression were per…

Modèle dynamique multiniveau et holonique pour la simulation d'un système complexe à grande échelle avec environnement spatial : Application à la sim…

2020

Nowadays, with the emergence of connected objects and cars, road traffic systems become more and more complex and exhibit hierarchical behaviours at several levels of detail. The multilevel modeling approach is an appropriate approach to represent traffic from several perspectives. Multilevel models are also an appropriate approach to model large-scale complex systems such as road traffic. However, most of the multilevel models of traffic proposed in the literature are static because they use a set of predefined levels of detail and these representations cannot change during simulation. Moreover, these multilevel models generally consider only two levels of detail. Few works have been inter…

Adopting the Emotions Course in the Italian context: A pilot study to test effects on social-emotional competence in preschool children.

2016

The purpose of this study was to adopt the Emotions Course (EC) in the Italian context and to examine preliminarily its effectiveness in accelerating the social-emotional competence and reducing maladaptive behaviors in preschool children. The study involved 143 children (73 males and 70 females) aged 3–5 years (M = 4.4 years, SD = .74), divided into two groups: 1) an experimental group (N = 69; 34 males and 35 females), consisting of classes in which teachers realized the EC, integrating it in their usual educational plan; 2) a control group (N = 74; 39 males and 35 females), consisting of classes in which teachers exclusively followed their usual educational plan that did not include the …
