Il diritto europeo e la «giustizia contrattuale»

2015

The essay deals with the issue of « contractual justice » in light of European private law. The author reports the extreme variety of problems brought under the formula « contractual justice » and tries to propose a definition of the notion, restricting it to the legal institutions that allow for judicial review of the contractual relationship, in view of its rebalancing. The most intricate issue concerns the conditions under which these forms of intervention, moreover very heterogeneous, can be accomplished. The paper analyzes the main opinions that range from the concepts of procedural justice to that of substantive justice, proposing a reading that goes beyond the procedural conceptions.

Optimal Starting Conditions for the Rendezvous Maneuver, Part 1: Optimal Control Approach

2008

We consider the three-dimensional rendezvous between two spacecraft: a target spacecraft on a circular orbit around the Earth and a chaser spacecraft initially on some elliptical orbit yet to be determined. The chaser spacecraft has variable mass, limited thrust, and its trajectory is governed by three controls, one determining the thrust magnitude and two determining the thrust direction. We seek the time history of the controls in such a way that the propellant mass required to execute the rendezvous maneuver is minimized. Two cases are considered: (i) time-to-rendezvous free and (ii) time-to-rendezvous given, respectively equivalent to (i) free angular travel and (ii) fixed angular trave…

The effect of the axial heat transfer on space charge accumulation phenomena in HVDC cables

2020

To date, it has been widespread accepted that the presence of space charge within the dielectric of high voltage direct current (HVDC) cables is one of the most relevant issues that limits the growing diffusion of this technology and its use at higher voltages. One of the reasons that leads to the establishment of space charge within the insulation of cables is the temperature dependence of its conductivity. Many researchers have demonstrated that high temperature drop over the insulation layer can lead to the reversal of the electric field profile. In certain conditions, this can over-stress the insulation during polarity reversal (PR) and transient over voltages (TOV) events accelerating …

The finger of Beelzebub. The consecration of judicial review of constitutionality in Portugal in 1911

2022

Without entirely breaking with the political review of constitutionality established in the 19th century, Portugal, which became a republic after the October 1910 revolution, decided to enshrine judicial review of constitutionality in its 1911 Constitution. The choice of the American model of diffuse review was intended to break with the main guarantee offered in the days of 'granted constitutionalism', when the moderating power of the King acted as guarantor of the Constitution alongside the political chambers. This was the aim of the promoter of this legal revolution, the law professor Afonso Costa, a strong man of the First Republic, who was able to convert his initially hostile republic…

The Construction of Collective Memory: from Franco to Democracy

2004

Collective memory is neither spontaneous nor random, but the result of a series of selective practices. It establishes group identity and sets power relations between groups. The author considers the process of selection through a case study of the transformation of Franco’s regime in Spain into a democracy. Collective memory of the time is shown to be organized around an event (the Munich Coalition or contubernio) and around the democratic transition. The author traces two opposing notions, negationist (denying any importance to Munich) and the pro-democratic, and concludes that the memory of the transition is only the memory of those who won the civil war, who were also those who enginee…

Investigating technical and pedagogical usability issues of collaborative learning with wikis

2012

Published version of an article in the journal: Informatics in Education : an International Journal. Wikis have been recently promoted as tools that foster collaborative learning. However, there has been little research devoted to the criteria that are suitable to address issues pertinent to collaborative learning. This paper proposes a set of criteria to explore technical and pedagogical usability issues of collaborative learning with wikis. The criteria are then used to evaluate students’ collaborative writing activities. The units of study are wikis that groups of students developed collaboratively using MediaWiki. This paper also reports on technical and pedagogical implications for the…

Staying at the front line in learning research is challenging because many fields are rapidly developing. One such field is research on the temporal aspects of computer-supported collaborative learning (CSCL). To obtain an overview of these fields, systematic literature reviews can capture patterns of existing research. However, conducting systematic literature reviews is time-consuming and do not reveal future developments in the field. This study proposes a machine learning method based on topic modelling that takes articles from a systematic literature review on the temporal aspects of CSCL (49 original articles published before 2019) as a starting point to describe the most recent deve…

Student-generated instructional videos facilitate learning through positive emotions

2016

The central focus of this study is a learning method in which university students produce instructional videos about the content matter as part of their learning process, combined with other learning assignments. The rationale for this is to promote a more multimodal pedagogy, and to provide students opportunities for a more learner-centred, motivating, active, engaging and productive role in their learning process. As such we designed a ‘video course’ where the students needed to produce an instructional video which could be used for university teaching. In addition to producing the video, the students needed to write a literature review of the topic of the video and a learning journal. At…

Social identification has been shown to be a protective resource for mental health. In this study, the relationships between social identification and emotional, as well as cognitive symptoms of test anxiety are investigated. Participants were university students diagnosed with test anxiety ( N = 108). They completed questionnaires regarding a range of psychopathologic stress symptoms, and their social identification with fellow students and with their study program. Results reveal negative relations between social identification and almost all investigated emotional and cognitive symptoms of test anxiety. Based on this study, interventions could be developed that strengthen the social ide…

Telemedicine Follow Up of Chronic Obstructive Pulmonary Disease Integrated into a Patient-Centered Health Care Team-Setting Impacts on Patient Empowe…

2017

Health care services are facing challenges with a growing ageing population prone to chronic conditions and multi-morbidities. Telemedicine applications have the potential to enhance patient’s safety at home by monitoring of chronic diseases, promoting coping and independence. The research project Patients and Professionals in Productive Teams aims to study patient-centered teamwork across organizational borders, supported by technology. This paper describes the research agenda for a study on how telemedicine follow-up impacts on chronic obstructive pulmonary disease patients’ quality of life and possible effects on patient empowerment, in the health region of Southern Norway. The outcome i…
