The fast diffusion equation with strong absorption: the istantaneous shrinking phenomenon
No full textQuesto lavoro verte sul fenomeno della contrazione istantanea del
supporto delle soluzioni non negative di una classe di equazioni nonlineari
paraboliche singolari. Vengono anche forniti risultati di esistenza,
unicità e confronto per i problemi di Dirichlet e di Cauchy, nonche'
alcune stime sul comportamento iniziale della frontiera libera.This paper deals with the phenomenon of the instantaneous shrinking
of the support of the non negative solutions of a class of nonlinear
singular parabolic equations. Existence, uniqueness and comparison
results for the Dirichlet and the Cauchy problems are also given,
together with some estimate of the initial behaviour of the free boundary
Assessing the quality of the learning outcome in vocational education: the Expero model
No full textPurpose – This paper aims to present an innovative model to evaluate the quality of the learning outcome in vocational education and training (VET) considering a wide approach that includes, in particular, stakeholders' expectations and perceptions.
Design/methodology/approach – The Expero model was implemented in various kinds of vocational schools and educational institutions in different European countries.
Findings – The model was validated through review by several international experts and by translation into a quality standard certification model.
Research limitations/implications – Expero needs a larger testing phase in non-European countries to validate its appropriateness. Different vocational systems in non-EU countries could enrich and widen the model in terms of transferability and sustainability as well as fostering cross-educational requirements and needs that may impact the quality of the learning outcome. The Expero model is mainly dedicated to vocational education and, in its current form, is not suitable to be applied to other levels of education (i.e. primary or secondary). Meanwhile, it seems promising in terms of its application in higher education institutions, in workplace learning, and in continuous professional training.
Practical implications – Expero permits analysis of the quality of the learning outcome, which constitutes the prior mission of a school. Being dedicated to the vocational sector, Expero is based on stakeholder evaluation, including school personnel, trainees, industries, companies and external bodies interested in a school's results. Applying the Expero model, a school can analyse its strengths and weaknesses in a systematic way; strengthening – or even creating – a collaborative network with its stakeholders finalised in improving learning outcome.
Originality/value – Among the various opportunities a school has to perform a quality assessment (ISO 9000, EFQM, CAF), Expero is the first model focused on the quality of the learning outcome based on multi-stakeholder data analysi
Mammography screening in Trieste: data quality, assessment of indicators and impact on the population
No full textIn this Section, "Statistics for screening", we want to emphasize that it is more and more important to use statistics to understand, to analyze and to evaluate the data of a screening, in order to describe the population and to take decisions and, even before, to learn to draw and design a screening itself.As highlighted by the title, using results from the project of mammography screening in the Province of Trieste, we want to focus in particular the importance of
- the quality of the data; without which it is no possible to make a correct statistics, and in this talk we show an example of the correction of the data concerning the blood group;
- the evaluation of the indicators, and here it is important to decide which are ‘informative indicators’, and how it is possible to read the output in a critical way;
- the impact of a screening on a population.
In this context it is evident the importance of a multidisciplinary work, and this is the experience started some years ago in our local reality, with the involvement of pathologists, surgeons, radiologists, radiotherapists, oncologists, physicists , mathematicians, statisticians, ... the different care and research contributions for breast disease in the province of Trieste
