L'ingegnerizzazione dei processi per il miglioramento delle performance delle aziende pubbliche

Nonostante gli approcci teorici più recenti, dal New Public Management al Public Value, sottolineino l’importanza della centralità dei bisogni del destinatario dei beni e dei servizi nella definizione dell’azione pubblica, il tema dell’ingegnerizzazione e della re-ingegnerizzazione dei processi organizzativi continua a rappresentare un aspetto poco affrontato nella Pubblica Amministrazione italiana. Nato come progetto fortemente interdisciplinare grazie al contributo di economisti aziendalisti, sociologi dell’organizzazione, psicologi del lavoro e ingegneri, questo lavoro si concentra sull’uso di alcuni strumenti capaci di migliorare la performance organizzativa, ma solitamente utilizzati in ambito privato, quali il Quality Funcion Deployment (QFD) e il Failure Modes and Effects Analysis (FMEA). Gli spazi organizzativi indagati, l’area di supporto alla ricerca scientifica dell’Ateneo di Cagliari e il servizio di asili nido del Comune di Cagliari, hanno consentito di approfondire la conoscenza dei processi produttivi in modo diffuso, agevolando la riscrittura di parte dell’architettura dei processi partendo dai bisogni dei destinatari degli output realizzati

Online learning of physics during a pandemic: A report from an academic experience in Italy

The arrival of the Sars-Cov II has opened a new window on teaching physics in academia. Frontal lectures have left space for online teaching, teachers have been faced with a new way of spreading knowledge, adapting contents and modalities of their courses. Students have faced up with a new way of learning physics, which relies on free access to materials and their informatics knowledge. We decided to investigate how online didactics has influenced students’ assessments, motivation, and satisfaction in learning physics during the pandemic in 2020. The research has involved bachelor (n = 53) and master (n = 27) students of the Physics Department at the University of Cagliari (N = 80, 47 male; 33 female). The MANOVA supported significant mean differences about gender and university level with higher values for girls and master students in almost all variables investigated. The path analysis showed that student-student, student-teacher interaction, and the organization of the courses significantly influenced satisfaction and motivation in learning physics. The results of this study can be used to improve the standards of teaching in physics at the University of Cagliar

Integralità della persona e cura educativa nell’opera di Édouard Séguin

A pupil of Itard and educator at Bicêtre from 1842 to 1843, Séguin is universally counted among the initiators of special education and his works represent a legacy of pedagogical importance central to any consideration of Special Pedagogy. In spite of this, the special pedagogical recommendations which emerge from his work are often linked to certain «weaknesses» in its theoretical development. The construct of will, in fact, assumes the character of a metaphysical assertion which is undefined, both with regard to the scientific tendencies of the time and on a methodological level. This impasse prompts clarification of the elements that stimulate the author’s cultural identity and the dimensions through which the moral nature of education is created. The emergence of the centrality of the subject, the founding principal of the educational process outlined by Séguin, takes on particular importance in the definition of the pedagogical and methodological principals which give substance, even today, to the process of caring for and emancipating people with intellectual disabilities

Development of a mirror-based LCPV module and test results

The design and the technical features of a low concentration photovoltaic module based on silicon solar cells are here presented, reporting manufacturing topics and results of experimental tests. The product here described has been developed, taking into account costs, efficiency, reliability, and investments required for its industrial production and for its commercial exploitationThe design of a specific low concentration photovoltaic module is described here, with a report of the results of the first experimental tests of its industrial version. The product is a 20× reflective concentrating photovoltaic module based on silicon solar cells. The optics were designed to mount these modules on 2-axis trackers with angular pointing accuracy of up to about ±4° without significant power loss. The high angular acceptance of the non-imaging optics permits the collection of a high fraction of the circumsolar light impinging on the module's frontal aperture, providing high direct normal irradiance efficiency in real operative conditions. Many technical features of the product are described here, in which features are the result of 5 years of product development in order to improve performance, reliability and cost issues

Women in science: la masterclass di Cagliari.

Il Dipartimento di Fisica dell'Università di Cagliari organizza da due anni una masterclass dedicata a bambine e ragazze in occasione dell'{International Day of Women and Girls in Science. Obiettivo dell'iniziativa, organizzata in collaborazione con la sezione locale dell'INFN ed inserita nell'ambito del Piano Lauree Scientifiche, è contrastare la differenza di genere ed avvicinare le ragazze alla Fisica. Bambine e ragazze provenienti da tutta la Sardegna sono coinvolte in attività di laboratorio con la supervisione di giovani ricercatrici. L'iniziativa è caratterizzata da un discussiongame sulle differenze di genere e dal video-collegamento con le ricercatrici del CERN di Ginevra

Optical simulation of Rondine® PV solar concentrators by two inverse characterization methods

In this paper we describe two optical characterization methods applied to photovoltaic solar concentrators. Both methods are of the 'inverse' type, where the light source is applied in place of the receiver in order to reverse the path of light inside the concentrator. The first method is the 'inverse illumination method', already known in the literature, whereas the second one is a method obtained by modifying the 'inverse luminescence method', operating with electroluminescent light. Both methods use ideal Lambertian sources for producing the inverse light and can be applied to any type of solar concentrator (photovoltaic or thermodynamic). The optical simulations show their equivalence in obtaining the angular distribution of the transmission efficiency function of Rondine® PV concentrators, but the original inverse illumination method requires a simpler configuration and significantly lower simulation times. © 2012 IOP Publishing Ltd
