Post-operative computed tomography imaging evaluation of ascending aorta surgery
2021
Ascending thoracic aorta disease is often a life-threatening condition. Aortic aneurysm and aortic dissection are the most frequent ascending aorta diseases requiring surgical intervention. Surgical repair techniques of the ascending aorta are various; they include reconstruction of the ascending aorta by using a graft with or without a prosthetic valve, reconstruction with a composite artificial graft or using a biological graft, and reconstruction of the ascending aorta with a composite graft preserving the native valve and arch repair. The radiologist plays a key role in the identification of post-operative complications; differentiation from normal postoperative findings is fundamental.…
Towards Automatic Testing of Reference Point Based Interactive Methods
2016
In order to understand strengths and weaknesses of optimization algorithms, it is important to have access to different types of test problems, well defined performance indicators and analysis tools. Such tools are widely available for testing evolutionary multiobjective optimization algorithms. To our knowledge, there do not exist tools for analyzing the performance of interactive multiobjective optimization methods based on the reference point approach to communicating preference information. The main barrier to such tools is the involvement of human decision makers into interactive solution processes, which makes the performance of interactive methods dependent on the performance of huma…

Decision-cache based XACML authorisation and anonymisation for XML documents
2012
Author's version of an article in the journal: Computer Standards and Interfaces. Also available from the publisher at: http://dx.doi.org/10.1016/j.csi.2011.10.007 This paper describes a decision cache for the eXtensible Access Control Markup Language (XACML) that supports fine-grained authorisation and anonymisation of XML based messages and documents down to XML attribute and element level. The decision cache is implemented as an XACML obligation service, where a specification of the XML elements to be authorised and anonymised is sent to the Policy Enforcement Point (PEP) during initial authorisation. Further authorisation of individual XML elements according to the authorisation specifi…
LA VALUTAZIONE DELLE PROPRIE COMPETENZE SOCIO-RELAZIONALI NEI LAVORATORI DEL SOCIALE: UNO STRUMENTO DI INDAGINE
2009
Coloro i quali hanno maturato una esperienza, anche piccola, presso una struttura di assistenza sociale e di cura, sanno quanto sia importante che gli operatori che la compongono siano dotati di alcune competenze che caratterizzano tale mestiere. Ci riferiamo alle cosiddette competenze sociali e relazionali, che unite alle conoscenze teoriche ed applicative completano il quadro delle richieste dell’ambiente lavorativo in questione. Il possesso di tali competenze consente il doppio vantaggio di agire correttamente con la propria utenza nell’erogare l’aiuto di cui necessita, e allo stesso tempo di preservare il lavoratore stesso da stati di forte stress legati ad una mansione che, senza gli “…
Relapse risk after autologous transplantation in patients with newly diagnosed myeloma is not related with infused tumor cell load and the outcome is…
2006
BACKGROUND AND OBJECTIVES: This European Group for Blood and Marrow Transplantation (EBMT) multicentre randomized phase III study was designed to assess the safety and efficacy of CD34+ selection in newly diagnosed myeloma patients undergoing autologous transplantation. DESIGN AND METHODS: One hundred and eleven patients responsive to initial chemotherapy were randomized to receive CD34+ selected (arm A) or unselected PBPC (arm B) after conditioning with high-dose melphalan and TBI. ASO-PCR was used to assess purging efficacy and reinfused tumor load. Tumor load could be assessed in 59 patients. RESULTS: CD34+ selection gave a median tumor cell depletion of 2.2 logs (0.77-5.96). No tumor ce…
A Low Cost Customizable Micro-ROV for Environmental Research - Applications, Advances and Challenges
2016
Summary Several shallow submarines areas are characterized by considerable releases of hydrocarbon gases, which, during earthquakes or volcanic activity, may suddenly and violently occur. In some instances, changes in chemical and physical properties of gas emissions, which are generated by geothermal systems connected to the volcanoes’ plumbing system, are important precursors of volcanic activity and useful indices for the study of the geothermal field. Furthermore, some superficial structures such faults, landslide slopes or archaeological relics should be studied with such a high detail that geophysical and bathymetric surveys are unable to provide. In response to the needs increasingly…
Learning Design for Future Higher Education – Insights From the Time of COVID-19
2021
The COVID-19 pandemic brought many challenges in higher education. All teaching and learning activities were moved online. Universities had to provide adapted solutions to facilitate learning and maintain students’ engagement. Online education implies creating new learning environments with the help of digital technologies. Beyond the process of acquisition of knowledge, teachers needed to facilitate cooperative learning, build positive relations, and reduce negative emotions. We provide some expert insights based on empirical observations on teaching and assessment practices connected with psychology models applied in education. The aim of the paper is to formulate specific learning design…
Metacognición en un proceso de aprendizaje autónomo y cooperativo en el aula universitaria
2015
In the new framework of the European Higher Education Area, teaching should be guided and managed in light of students learning. Students need to activate the necessary competencies to carry out an autonomous learning. In this context, an experience was conducted in the subject Psychology of Education with the first year Pre-service Elementary School Teachers from theUniversity ofLa Rioja. The objective was to know the metacognitive analysis made by students when they had to do tasks that required both autonomous and cooperative strategies. As expected, results from the metacognitive analysis revealed a positive evaluation of this methodology. Moreover, students reported having achieved a b…
La teoría de la autodeterminación : un marco motivacional para el aprendizaje basado en proyectos
2019
Resumen basado en el de la publicación Título, resumen, palabras clave en español e ingles Se describe cómo la mejora de la motivación escolar requiere de un marco teórico que permita establecer estrategias sencillas para guiar a los docentes en su práctica educativa. La teoría de la autodeterminación, con un corpus científico extenso, ha ayudado a entender mejor los elementos que inciden sobre la motivación en la práctica. Según este marco teórico, las formas autónomas de motivación requieren del desarrollo de tres necesidades psicológicas básicas: autonomía, competencia y relación con los demás. En el medio escolar, estas necesidades se ven favorecidas a través de contextos que fomentan l…
