Back to School : Labor-Market Returns to Higher Vocational Schooling
2019
This paper examines the labor-market returns to a new form of postsecondary vocational education: vocational master's degrees. We use individual fixed effects models on a matched sample of students and non-students from Finland to capture any time-invariant differences across individuals. We find that attendance in vocational master's programs leads to an earnings increase of more than seven percent five years after entry. The estimated effect remains positive even if selection on unobservables is twice as strong as selection on observables. Earnings gains are similar by gender and age, but they are marginally higher for those in the health sector than for those in the business or technolog…
Costruzione e validazione del questionario DIDLab “La didattica Laboratoriale: apprendimenti e stili di conduzione con l’approccio IBSE”
2021
Il presente lavoro espone gli esiti della costruzione e validazione del questiona-rio “La didattica Laboratoriale: apprendimenti e stili di conduzione con l’ap-proccio IBSE” finalizzato a misurare il grado di conoscenza dell’approccio In-quiry-Based Science Education e lo stile di conduzione nella didattica labora-toriale, che ha visto coinvolti 523 corsisti del corso di specializzazione per le attività di sostegno didattico dell’Università degli Studi di Palermo; il test di misurazione costruito è composto da 42 item suddiviso in cinque macro-aree su scala Likert a 5 punti. Dall’analisi quantitativa condotta è emerso che il questionario ha buona con-cordanza, pensato per indagare sulle con…
Inquiry based Laboratory. Una ricerca con i futuri docenti di sostegno.
2021
La formazione degli insegnanti in laboratorio è particolarmente rilevante perché consente di a t t i v a r e p r o c e s s i d i i n s e g n a m e n t o / apprendimento in cui gli alunni diventano protagonisti dei propri percorsi. Il laboratorio rappresenta la modalità trasversale che caratterizza la didattica e la formazione dei futuri docenti. Attraverso la didattica laboratoriale gli studenti hanno la possibilità di confrontarsi, di mettere in atto le abilità critiche, logiche e creative per esplorare la realtà circostante. Ciò si coniuga perfettamente con le possibilità che garantisce un laboratorio scientifico Inquiry-Based Learning centrato sul processo di investigazione. Nel presente…
Digital citizenship and the use of mobile devices in educational institutions
2018
Training in digital competence is one of the concerns in the educational sphere and, either at European, state and regional levels, policies have been developed for promote the responsible use of technologies in digital citizenship and, in particular, with minors and adolescents who live in a digital society. From Europe 2020 Strategy (European Commission, 2010), as well as the strategic framework: Education and Training 2020 (European Commission, 2009), it has been proposed a set of priorities that will be translated into national objectives for all member countries of the European Union, as a purpose for the year 2020. In this sense, following the European directives, in the Spanish conte…
Dispositifs interculturels à distance
2008
In the context of intercultural online communication, certain dimensions of ICT we might call “figures sensibles” (Boutaud 2006) can be critically useful to understand co-construction, especially when these dimensions are also constitutive of an educational context. Thus, transparency, performance and conviviality help us interpret what can be called collaborative online interaction. Dispositive memory thrives on these dimensions and completes them. It explains in part the continuity of socially constructed identity of the community in question. It is the community aspect which in our context imposes itself despite cultural differences.
A novel framework for MR image segmentation and quantification by using MedGA
2019
BACKGROUND AND OBJECTIVES: Image segmentation represents one of the most challenging issues in medical image analysis to distinguish among different adjacent tissues in a body part. In this context, appropriate image pre-processing tools can improve the result accuracy achieved by computer-assisted segmentation methods. Taking into consideration images with a bimodal intensity distribution, image binarization can be used to classify the input pictorial data into two classes, given a threshold intensity value. Unfortunately, adaptive thresholding techniques for two-class segmentation work properly only for images characterized by bimodal histograms. We aim at overcoming these limitations and…
Computer-Assisted Approaches for Uterine Fibroid Segmentation in MRgFUS Treatments: Quantitative Evaluation and Clinical Feasibility Analysis
2019
Nowadays, uterine fibroids can be treated using Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS), which is a non-invasive therapy exploiting thermal ablation. In order to measure the Non-Perfused Volume (NPV) for treatment response assessment, the ablated fibroid areas (i.e., Region of Treatment, ROT) are manually contoured by a radiologist. The current operator-dependent methodology could affect the subsequent follow-up phases, due to the lack of result repeatability. In addition, this fully manual procedure is time-consuming, considerably increasing execution times. These critical issues can be addressed only by means of accurate and efficient automated Pattern Recognition ap…
Monitoring pH and ORP in a SHARON reactor
2011
This paper analyses the valuable information provided by the on-line measurements of pH and oxidation reduction potential (ORP) in a continuous single high ammonia removal over nitrite (SHARON) reactor. A laboratory-scale SHARON reactor equipped with pH, ORP, electric conductivity and dissolved oxygen (DO) probes has been operated for more than one year. Nitrogen removal over nitrite has been achieved by adding methanol at the beginning of anoxic stages. Time evolution of pH and ORP along each cycle allows identifying the decrease in nitritation rate when ammonia is consumed during the aerobic phase and the end of the denitrification process during the anoxic phase. Therefore, monitoring pH…
Trayectorias laborales de autóctonos e inmigrantes en España: entre la convergencia y la segmentación. Un análisis de la Muestra Continua de Vida Lab…
2011
Este trabajo es un análisis de las trayectorias laborales de trabajadores autóctonos y de origen extranjero a partir de la muestra continua de vidas laborales de la seguridad social (en adelante MCVL). Se exploraron dos hipótesis. Por un lado, la antigüedad en el mercado de trabajo y la cualificación producen con el tiempo una “asimilación ocupacional de la inmigración” con los trabajadores autóctonos; por otro, la inserción de la inmigración en determinados nichos del mercado laboral limita la convergencia con los trabajadores autóctonos. Los resultados señalan que la asimilación se produce de forma estratificada en algunas pocas categorías profesionales, mientras persiste la brecha de acu…
