Sustainable production and consumption in remote working conditions due to COVID-19 lockdown in Italy: An environmental and user acceptance investiga…

2021

Abstract In response to the disruptive changes brought upon our society by the COVID-19 pandemic, most work activities and service providers had to resort to remote working. This is credited to reduce emissions for transportation, however the role of forced confinement within dwellings, especially if not designed for hosting working stations, deserves to be properly evaluated in terms of both user acceptance and long-term environmental impact. In this work, a dedicated survey campaign is used for investigating the potential pros and cons of remote working. In more detail, logistic regression and generalized linear models are used for capturing the effect of several independent variables on …

Relationships between leadership and professionals' job attitudes and perceptions: Comparison of two leadership models

1996

Abstract The aim of this study was to investigate the power of the Average Leadership Style (ALS) and Vertical Dyad Linkage (VDL) models of leadership in explaining relationships between leader's initiating structure behaviour and consideration behaviour, and subordinates' attitudes and perceptions. The considered dependent variables were five facets of job satisfaction, two role stress variables (role conflict and ambiguity), one role strain indicator (job tension), and four dimensions of workteam climate. The relationships were investigated in two occupational samples comprising 127 family physicians and 155 nurses working in 28 Primary Health Care Teams. Within and between analysis (WABA…

How personal resources predict work engagement and self-rated performance among construction workers: A social cognitive perspective

2014

Traditionally, research focussing on psychosocial factors in the construction industry has focused mainly on the negative aspects of health and on results such as occupational accidents. This study, however, focuses on the specific relationships among the different positive psychosocial factors shared by construction workers that could be responsible for occupational well-being and outcomes such as performance. The main objective of this study was to test whether personal resources predict self-rated job performance through job resources and work engagement. Following the predictions of Bandura's Social Cognitive Theory and the motivational process of the Job Demands-Resources Model, we exp…

Organizational Learning Capability and Job Satisfaction: an Empirical Assessment in the Ceramic Tile Industry

2009

Organizational learning capability has been considered an essential issue of an organization's effectiveness and potential to innovate and grow. Although its positive effects on organizations and employees are generally assumed, there is no empirical evidence of its positive association with employee attitudes such as job satisfaction. This paper aims to investigate the relationship between organizational learning capability and job satisfaction through the questionnaire responses of 157 employees from eight companies in the Spanish ceramic tile industry. Results suggest that organizational learning capability and job satisfaction are strongly linked.

Moderating influence of organizational justice on the relationship between job insecurity and its outcomes: A multilevel analysis

2010

A great amount of research has illustrated the evident prevalence of job insecurity in working life and its harmful outcomes for employees and organizations. Some authors have identified factors that can reduce this negative influence. However, up until now, most of these factors have only been studied at an individual level, without taking into account the fact that contextual conditions can play a moderating role in organizations. Following this perspective, this article analyses the moderator role of organizational justice and organizational justice climate in the relationship between job insecurity and its outcomes. The study was carried out with a sample of 942 employees from 47 Spanis…

Exploring working conditions as determinants of job satisfaction: an empirical test among Catalonia service workers

2011

Job satisfaction is particularly important in the service industries since it involves direct contact with customers and thus has a direct influence on company performance. This paper analyses the impact of 10 working conditions on job satisfaction by means of structural equation modeling in a representative stratified random sample of 1553 service sector employees in Catalonia, Spain. Significant effects in social aspects (recognition of a job well done and social support) were found, followed by psychological loads (emotional demands and job insecurity) and by task contents (development and meaning, and predictability). These variables explained 50% of the variance in job satisfaction.

Guaranteed tuning of PID controllers for parametric uncertain systems

2004

This paper presents a methodology for tuning the controller of a parametric uncertain plant in order to guarantee the satisfaction of specifications. These specifications are defined by means of an interval reference model that represents the set of satisfactory time or frequency behaviors. The controller synthesis is then formulated as a set-inclusion problem in the frequency domain. Interval techniques for the solution of constraint satisfaction problems are applied to design fixed-structure controllers in a guaranteed manner. In particular, PID controllers are considered since they are widely used in industry.

Is the Kidscreen-27 a valid measure of health-related quality of life in 10-year-old Norwegian children?

2015

The aim of this study was to investigate the reliability and validity of the Norwegian Kidscreen-27 questionnaire, a measure of generic health-related quality of life, in 10 year-old children. The Kidscreen-27 consists of five domains and was validated in a sample of 56 school children (29 boys). The children completed the questionnaire at three different time points during two consecutive school days. For convergent validity, the study was powered to detect a statistically significant correlation coefficient of 0.4. Cronbach's alpha values ranged from 0.73 to 0.83. Floor effects were all zero and ceiling effects ranged from 1.7% to 23.7%. Intraclass correlation values over time ranged from…

Finnish pre-service teachers’ perceptions of their strategic learning skills and collaboration dispositions

2019

To support the development of pupils’ 21st-century skills, teachers themselves must also be competent in these skills and learn them during pre-service teacher education. The aim of this study is to investigate what kind of profiles emerge among Finnish first-year pre-service teachers’ (N = 872) in terms of perceptions of their strategic learning skills and collaboration dispositions and what background variables explain membership of the profiles found. Latent profile analysis showed five student profiles corresponding to perceived strategic learning skills and collaboration dispositions. The most robust factor explaining the membership of the profiles was life satisfaction. Pre-service te…
