Gender differences in Italian STEM degree courses: a discrete-time competing-risks model
2020
In this paper, we highlight possible gender differences in performance of students attending Italian university STEM degree courses, controlling for sociodemographic and territorial variables.We used the micro-data from the Italian Ministry of Education, Universities and Research database of the 2011-12 freshmen cohort enrolled at an Italian bachelor university degree course. The analysis was dealt with by fitting a discrete-time competing-risks model. Bachelor degree graduation, dropout, and change to non-STEM courses were considered as competing events. The aim is to highlight gender gaps in the student performance, and the STEM courses where this gap is more critical.
Age, training, and previous experience predict race performance in long-distance inline skaters, not anthropometry
2012
Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph Alexander | Rosemann, Thomas | Lepers, Romuald; International audience; ''The association of characteristics of anthropometry, training, and previous experience with race time in 84 recreational, long-distance, inline skaters at the longest inline marathon in Europe (111 km), the Inline One-eleven in Switzerland, was investigated to identify predictor variables for performance. Age, duration per training unit, and personal best time were the only three variables related to race time in a multiple regression, while none of the 16 anthropometric variables were related. Anthropometric characteristics seem to be of no importance for a fast …
L'analyse statistique du profil sensoriel revisitée par une approche base de données
2015
During a sensory evaluation, trained subjects taste and score products on differentdescriptors in order to obtain a descriptive profile of these products. The data are thenanalyzed by several statistical methods (PCA, ANOVA…) in order to monitor the subjectperformances and map the product space.This work aims to revisit these statistical methods thanks to the analysis of a large number ofdatasets of sensory profiling data from the SensoBase (a database containing more than athousand of datasets). Different statistical methods of mapping and analysis ofperformances were compared, then improved. We mainly focused on the so-called scalingeffect (tendency of the subject to spread his scores mor…
La motivation des étudiants à l’entrée à l’université : quels effets directs ou indirects sur la réussite ?
2015
L’enjeu de cet article réside dans la mesure du rôle des capacités motivationnelles des étudiants sur la réussite universitaire, en adoptant une démarche quantitative et intégrative. À cette fin, les données récoltées sur des étudiants en première année de licence de trois filières permettent de contrôler un ensemble de facteurs relatifs aux caractéristiques socio-démographiques et scolaires des étudiants. Mesurée dans le cadre de la théorie de l’autodétermination, il ressort des analyses que la motivation intrinsèque exerce une influence positive tandis que l’amotivation se traduit par de moins bonnes performances. Par ailleurs, la motivation est un atout pour les bons étudiants, mais ne j…
Alignment of strategy and structure in local government
2020
Strategic positioning and structural alignment in the public sector is a neglected area of research. This paper analyses the strategic positions of prospectors, defenders and reactors and structural alignment in Norwegian municipalities. Top managers responding to a survey perceived that the municipalities did align their organizational structures to the strategic positions for prospectors and defenders, but not for reactors, as hypothesized, but these relationships were modest. The top managers often found it difficult to provide consistent responses on their organizations’ choices of strategic positions. The authors show that many Norwegian municipalities have minimal alignment of their o…
Towards the Environmental Sustainability of the Construction Sector: Life Cycle Environmental Impacts of Buildings Retrofit
2022
In the context of the need for carbon emissions reduction, the buildingsector, as one of the most energy intensive one, needs tools and approaches towards carbon neutrality and the increase of the buildings overall energy performances. The paper proposes an integrated approach towards the environmental performances analysis of a small neighborhood having as goal the achievement of the Positive Energy District target and the assessment of its environmental impacts. The methodology proposed includes building modeling and dynamic energy simulation using the Energy Plus engine and a simplified Life Cycle Assessment approach. Two scenarios are investigated: i) the existing neighborhood, ii) the …
Applying System Dynamics Modeling To Foster a Cause-and-Effect Perspective in Dealing with Behavioral Distortions Associated with a City’s Performanc…
2015
This paper aims to show how applying system dynamics methodology to performance management can provide a powerful modeling perspective enabling public sector organizations to prevent, detect, and counteract behavioral distortions associated with performance measurement. A dynamic performance management approach is able to support performance management system designers in outlining and implementing a consistent set of measures that can allow public sector decision-makers to pursue sustainable organizational learning and development. This perspective implies a major shift from a static to a dynamic picture of organizational processes and results. It means framing delays between causes and ef…
Bus Speed Estimation By Neural Networks To Improve The Automatic Fleet Management
2007
In the urban areas, public transport service interacts with the private mobility. Moreover, on each link of the urban public transport network, the bus speed is affected by a high variability over time. It depends on the congestion level and the presence of bus way or no. The scheduling reliability of the public transport service is crucial to increase attractiveness against private car use. A comparison between a Radial Basis Function network (RBF) and Multi layer Merceptron (MLP) was carried out to estimate the average speed, analysing the dynamic bus location data achieved by an AVMS (Automatic Vehicle Monitoring System). Collected data concern bus location, geometrical parameters and tr…
Toward a European Eco-label brand for residential buildings: Holistic or by-components approaches?
2011
The Eco-label scheme is becoming ever more important in the environmental certification of products and services, especially in light of the recent ambitious aim of containing greenhouse emissions and improving the efficiency of utilizing energy sources. A recently-introduced hypothesis concerns the European Eco-label scheme relating to buildings, in the awareness that the construction industry is of primary importance to the whole economic and social life of states. This scheme should adopt an integrated approach to environmental problems and include construction, day-to-day management, and the possible disposal of building materials, throughout the life cycle of the building. In addition,…
