Do perceptions of being treated fairly increase students’ outcomes? Teacher–student interactions and classroom justice in Italian adolescents     

Luisa Molinari  Giuseppina Speltini  Stefano Passini 《Educational Research and Evaluation》2013,19(1):58-76

In this study, we have investigated the associations between the students’ perceptions of teachers’ interpersonal behaviour and some school outcomes – namely, academic achievement, learning motivation, and a sense of class belonging – considering the mediating role of classroom justice. Moreover, the impact of the school type was analysed. The research was performed on a population of 614 Italian students enrolled in 2 different types of secondary school, one with an academic orientation, the other with a vocational orientation. Structural equation modelling (SEM) was used to see the effect of the teachers’ behaviour on the dimensions of justice (i.e., equality, equity, needs, and interpersonal) and that of all these variables on academic achievement, learning motivation, and class belonging. The mediation role of classroom justice was confirmed by the analyses, and so was the impact of the school's orientation. Limitations to the study and future research ideas have also been outlined.  相似文献   

CFD application to optimise the ventilation strategy of Senate Room at Palazzo Madama in Turin (Italy)     

Stefano Paolo Corgnati  Marco Perino 《Journal of Cultural Heritage》2013,14(1):62-69

Over the last years, there was an increasing interest in keeping suitable microclimatic conditions for the preservation of artefacts: the artefacts preservation requirements may diverge from those of the museums visitors, willing to enjoy the works of art in a situation of psycho-physical wellness. The HVAC designers and engineers will have then to cooperate closely with the curator, in order to define a compromise between conflicting environmental performance requirements. In particular at the stage of air-conditioning system design or retrofit, it is extremely important to carry out a series of preliminary analysis to evaluate and monitor the existing environmental conditions and to anticipatory simulate and predict the post-intervention conditions. To this aim, advanced fluid-dynamic investigation tools (Computational Fluid Dynamic [CFD] techniques) enable to deal with the specificity of such topics and provide a useful decision-making support.  相似文献   

From local networks of SMEs to virtual districts?: Evidence from recent trends in Italy     

Maria Chiarvesio  Eleonora Di Maria  Stefano Micelli   《Research Policy》2004,33(10):1509-1528

Industrial districts as local networks of small and medium enterprises (SMEs) rooted their competitiveness in a mix of economic relationships and social ties. Recently, network technologies have promised gains of efficiency through a reduction in transaction costs and showed new commercial opportunities for small firms. Despite the morphological similarities between industrial districts and network technologies, a longitudinal analysis of ICT diffusion within Italian districts shows that the foreseen convergence between the district economic model and new technologies should not be taken for granted. The observed specific evolutionary paths concerning technology innovation in local systems also opens-up issues of economic policy.  相似文献   

The Development and Psychometric Properties of the Teacher Social Stress Scale-Student Related (TSS-Sr)     

Stefano Taddei  Bastianina Contena  Alessandro Pepe  Eva Venturini 《Scandinavian Journal of Educational Research》2019,63(2):272-284

Teacher burnout is a growing phenomenon that may dramatically reduce the quality of life of both teachers and students. Many studies have conceptualized teaching as a high-contact profession and, focusing on the emotional exhaustion dimension of burnout, they have highlighted the relation with students as a key dimension of teachers’ stress. This paper presents an original instrument (TSS-Sr) to measure teachers’ stress related to the interaction with their pupils. It provides the psychometric characteristic of this scale. Results support a model of measurement of teacher social stress based on four dimensions: verbal aggression, dislike students, awkward reactions, demanding requests. Implications about the use and the applications of this instrument are discussed.  相似文献

Divide to connect: Reorganization through R&D unit spinout as linking context of intra-corporate networks     

Bruno Cirillo  Stefano Breschi  Andrea Prencipe 《Research Policy》2018,47(9):1585-1600

The paper examines the formation of clique-spanning ties in intra-corporate co-invention networks, by focusing on the impact of R&D unit spinouts. Using data on thirty-one spinouts in eight large U.S. information and communication technology corporations, we show that the reorganization of R&D units through corporate spinouts is associated with an increase in the extent to which inventors employed in the unit collaborate with inventors located in other cliques within the corporate co-invention network. Interestingly, the spinout effect spills over to all members of the clique of spun-out inventors, also including those who remain with the parent firm. The interpretation of these empirical findings, grounded on existing theories and on the views of inventors and executives involved in the reorganization events, suggests that corporate spinouts generate a shock in intra-corporate research collaboration dynamics, which loosens clique lock-in effects and contributes to reset cliques’ boundaries in the intra-corporate research network.  相似文献   

The economic impact of technological procurement for large-scale research infrastructures: Evidence from the Large Hadron Collider at CERN     

Paolo Castelnovo  Massimo Florio  Stefano Forte  Lucio Rossi  Emanuela Sirtori 《Research Policy》2018,47(9):1853-1867

The Large Hadron Collider at CERN, the European Organisation for Nuclear Research, is the world’s highest-energy particle accelerator. Its construction (1995–2008) required frontier technologies and close collaboration between CERN scientists and contracting firms. The literature on “Big Science” projects suggests that this collaboration generated economic spillovers, particularly through technological learning. CERN granted us access to its procurement database, including suppliers of LHC from 35 countries for orders over 10,000 Swiss Francs. We gathered balance-sheet data for more than 350 of these companies from 1991 to 2014, which include the years before and after that of the first order received. The study assesses, in quantitative terms, whether becoming a CERN supplier induced greater R&D effort and innovative capacity, thus enhancing productivity and profitability. The findings – which controlled for firms’ observable characteristics, macroeconomic conditions, and unobserved time, country, industry and firm-level fixed effects – indicate a statistically significant correlation between procurement events and company R&D, knowledge creation and economic performance. The correlation is chiefly driven by high-tech orders; for companies receiving non-high-tech orders, it is weaker, or even statistically not significant.  相似文献   

Tools in practice, mathematics in use     

Stefano Pozzi  Richard Noss  Celia Hoyles 《Educational Studies in Mathematics》1998,36(2):105-122

We seek to analyse the notion of structuring resources and their role in shaping mathematical activity, and more broadly to add to our understanding of mathematical epistemologies in workplace settings. Our analysis is of two nursing activities – drug administration and fluid balance monitoring – based on data collected in an in–depth study of paediatric nurses on the ward. In the first activity, we examine ways in which nurses conceptualise ratio and proportion problems, while in the second, we provide a case study of two nurses discussing conflicting strategies when monitoring the fluid balance of a patient. We discuss the ways in which the available resources give mathematical and professional meanings in these situations and draw out some implications for the design of viable didactical strategies in vocational mathematics teaching.  相似文献   

COMPUTER AIDED CREATIVITY?     

Virginio Cantoni  Stefano Levialdi 《High Ability Studies》1995,6(2):181-187

Human‐computer cooperation in the creative process has a twofold nature: The human being can be either active or passive during the execution of a computer program. In the first case the human may change the course of action of the program and suggest new paths; in the second the human being may detect a particular outcome—autonomously generated by the machine–as the most interesting one. The first cooperation process is the well known one of Human Aided Creativity²(HAC) while the second one may be called Computer Aided Creativity (CAC) and will be analysed here.  相似文献
