The choice of tradition and the tradition of choice: Habermas’ and Rorty’s interpretation of pragmatism
1999
The paper is aimed at discussing two interpretations of pragmatism in a broader framework of general rules of philosophical interpretation. J. Habermas’ and R. Rorty’s uses of pragmatism are considered in detail and confronted with general assumptions of pragmatic philosophy. It is shown that in both cases the original ideas of pragmatism are changed in order to fit the philosophies of interpreters. The paper ends with discussion of a possibility of applying the rule of interpretative charity and dialogue to philosophical analyses.
Frequency dynamics of power systems with temporally distributed disturbances
2021
Abstract The frequency dynamics and stability of power systems is essentially affected by nature and characteristics of the disturbances occurring in the system. Conventionally, frequency transients are examined assuming a single disturbance applied at a given time. However, actual incidents in the power systems can be generally composed of a temporal sequence of events, and thus characterized by multiple power imbalances of different magnitudes and time offsets. The consideration of the effects of the temporal distribution of power imbalances is important for two main reasons: the impact on the frequency dynamics of the system in terms of frequency metrics such as minimum instantaneous fre…
Intelligent learning environment for better student’s academic performance
2021
In this paper, the authors aim to develop an intelligent learning environment model designed to improve students’ academic performance. Methodology: Referring to the litarature, the authors identified and analyzed a number of relevant issues that influence the specific components of an intelligent learning environment. These aspects were quantified using performance indicators defined on the basis of the specific objectives of each aspect chosen. Results: Following the analysis, the authors developed a model of intelligent learning space, and for its representation, we used conceptual modeling. Conclusions: Finally, the authors propose the prevalidation of the model using the dynamic modeli…
A methodological approach to analyze the territorial appropriation of high-speed rail from interactions between actions and representations of local …
2019
International audience; Because it is difficult to separate the specific transport impact from other factors influencing economic and spatial development, the focus in research is increasingly on understanding the process by which territorial changes occur in order to explain how economic and social agents and local authorities have appropriated new transportation systems. This appropriation plays a crucial part in territorial dynamics. The diversity of economic and spatial changes produced by high-speed rail indicates the existence of multiple modes of appropriation which vary according to the location of stations, the mobilization of local stakeholders confronted with the transport operat…
Negotiation mechanisms for capacity allocation in distributed enterprises
2003
Abstract The paper proposes an agent based approach for the capacity allocation in distributed enterprises, characterized by complex and articulated organizations and by geographically distributed production capacities contended by many product families. In such a scenario the process of allocating the production capacity to the single customer order is one the major bottlenecks of the production planning activity as far as many organizational decisional levels are involved and market turbulence implies a continuous retuning of the capacity allocation plan. A high grade of reactiveness is needed. Agent based approaches and negotiation models, by decentralizing the decisional control and sim…
An inductive learning perspective on automated generation of feature models from given product specifications
2018
For explicit representation of commonality and variability of a product line, a feature model is mostly used. An open question is how a feature model can be inductively learned in an automated way from a limited number of given product specifications in terms of features.We propose to address this problem through machine learning, more precisely inductive generalization from examples. However, no counter-examples are assumed to exist. Basically, a feature model needs to be complete with respect to all the given example specifications. First results indicate the feasibility of this approach, even for generating hierarchies, but many open challenges remain.
Pilot study on university students' opinion about STEM studies at higher education
2020
The percentages of women enrolled in higher education in the STEM sector are significantly lower than those of men. Overall, gender representation in science, technology, engineering and mathematics degrees in Europe is not balanced. The Leaky Pipeline phenomenon, marked by gender stereotypes, makes the latent gender gap a relevant topic of study. Studies exist on academic performance, self-perception, self-efficacy, outcome expectations; however, studying gender stereotypes linked to STEM studies is also essential. It is necessary to know the social and family context in which young people have grown up, as well as their perception of such studies. To study gender stereotypes of university…
Les effets de la réforme sur le sentiment de professionnalisation des futurs enseignants
2013
S’inscrivant dans un cadre européen, la formation des enseignants en France fait l’objet, depuis 2005, de réformes profondes dont l’enjeu porte sur un renforcement des compétences professionnelles et un adossement des savoirs enseignés à la recherche. Partant de données longitudinales recueillies auprès de 3 générations d’étudiants inscrits dans le nouveau master « enseigner, éduquer, apprendre » ouvert à l’université de Bourgogne en 2010, cette recherche met en lumière la façon dont les étudiants se destinant au professorat des écoles perçoivent la qualité de leur professionnalisation. Malgré le sentiment de ne pas être suffisamment préparés pour l’exercice de leur métier, le discours des …
Older Adult Mentors and Youth at Risk: Challenges for Intergenerational Mentoring Programs in Family-Centered Cultures
2012
This article poses some preliminary reflections about the viability of youth mentoring schemes in family-centered cultural contexts based on a pilot experience developed in Spain within the framework of a project aiming to train older adults as youth mentors in five European countries. After an introduction to the field of intergenerational mentoring, a description of the pilot program follows, with special attention paid to the development of the Spanish local project. Drawing on the project evaluation, some open questions are posed regarding (a) the optimal institutional framing for an intergenerational mentoring program and (b) the challenge with social representation of the mentor role.
A computer system to perform structure comparison using TOPS representations of protein structure
2001
We describe the design and implementation of a fast topology-based method for protein structure comparison. The approach uses the TOPS topological representation of protein structure, aligning two structures using a common discovered pattern and generating measure of distance derived from an insert score. Heavy use is made of a constraint-based pattern-matching algorithm for TOPS diagrams that we have designed and described elsewhere (Bioinformatics 15(4) (1999) 317). The comparison system is maintained at the European Bioinformatics Institute and is available over the Web at tops.ebi.ac.uk/tops. Users submit a structure description in Protein Data Bank (PDB) format and can compare it with …
