Conceptual evaluation of methods for engineering situational ISD methods
2006
In the past decades a large variety of techniques and methods have been introduced for software engineering (SE) and information system development (ISD). Despite this plurality, there is a need in organizations and projects to customize methods that match with their specific needs. Method engineering (ME) is the process by which a situational method is developed, customized and configured. ME work has appeared to be difficult and burdensome to carry out in practice. One reason for this is a lack of adequate methodical support. In this article, we profile and evaluate conceptually, using a contextual framework as a basis, seven comprehensive ME artifacts (i.e. techniques, procedures and met…
Materials Communicating with the BIM: Aims and First Results of the McBIM Project
2019
This paper introduces McBIM, a French national research project working on on-line monitoring on concrete structure. This project gathers 3 french laboratories (the CRAN, LAAS and LIB) associated with one company (360SmartConnect/FINAO SAS) that are working together from 2018 to 2021. It proposes 1) to design a “communicating concrete”, made of concrete equipped with embedded low-energy wireless microsensor network, able to manage and exchange data using BIM standards, and 2) to demonstrate the usefulness of this approach across several building lifecycle phases, namely the manufacturing, construction and exploitation phases for structural health monitoring. The paper will first start by in…
Assessing pupils' skills : Implications for research in education
2010
10002; The object of this article is the structure and evolution of skills developed by pupils at primary level. Starting from an analysis of the panel data provided by the French Ministry of Education, the main object of this paper is an original measurement of skills using structural models. The findings of this research raise two complementary issues. The first issue concerns the cross-curricular nature of skills suggesting a logic of disciplinary interdependence. The acquisition of a skill may be strongly correlated to the acquisition of other skills belonging to the same subject area or to other subject areas. The notion of a set of skills is used to account for the connections between…
Structural analysis of the back supporting structure of the DEMO WCLL outboard blanket
2017
Abstract Within the framework of EUROfusion R&D activities an intense research campaign has been carried out at the University of Palermo, in close cooperation with ENEA Brasimone, in order to investigate the thermo-mechanical performances of the outboard segment Back-Supporting Structure (BSS) of the DEMO Water-Cooled Lithium Lead breeding blanket (WCLL). In particular, the configuration of the outboard segment BSS, purposely set-up by the WCLL project team during 2015 according to the blanket “multi-module system” concept, has been taken into account in order to study its steady state thermo-mechanical behaviour, paying attention to the simulation of both modules-BSS and BSS-vacuum vessel…
Wartość informacji w systemie informacyjnym w ocenie jej jakości
2018
The purpose of the article is to determine to what extent and how to evaluate the value of information available in the information system when assessing its quality. Such an evaluation, especially for systems operating on the Internet, is absolutely necessary because of the constant and rapid growth of the information resources available there, bearing the unnecessary economic costs of their poor quality and related to that negative social phenomena. The quality of information is a multidimensional category and requires evaluation of great number of different attributes. Are there among conceptual models for evaluating the quality of information also such that require evaluating the value …
The relationship between professional tournament structure on the national level and success in men's professional tennis.
2003
This article discusses the relationship between a nation's men's professional tennis tournament structure and that nation's success in the international men's game. The 2002 men's professional tennis tournament calendar provided the distribution of events on the top thirty nations. Criteria for a nation's success in men's professional tennis were: nation's number of players with ATP points, nation's number of players in the top 200 ranking, and the combined ATP ranking of a nation's top 5 male players. Pearson correlations were performed between the number of tournaments and each criterion. Results showed a considerable variation in the number of events ranging between 67 (United States) an…
Emotional Dimensions of User Experience ? A User Psychological Analysis
2014
User psychology is a human–technology interaction research approach that uses psychological concepts, theories, and findings to structure problems of human–technology interaction. As the notion of user experience has become central in human–technology interaction research and in product development, it is necessary to investigate the user psychology of user experience. This analysis of emotional human–technology interaction is based on the psychological theory of basic emotions. Three studies, two laboratory experiments, and one field study are used to investigate the basic emotions and the emotional mind involved in user experience. The first and second experiments study the measurement of…
Opposing Forces of Social Attraction and Social Avoidance Drive Network Modularity
2020
SUMMARY: How interactions between individuals contribute to the emergence of complex societies is a major question in biology. Nonetheless, little remains known about how simple rules of social attraction (e.g. to information) and social avoidance (e.g. of disease) interact to shape sociality. We developed an individual-based model where individuals choose with whom to interact depending on the status of group mates (informed and/or infected). Statistical models indicate that the emergence of social structure depends on the cost/benefit trade-offs underlying the system. Critically, pressures that optimize social relationships – i.e. minimize risky connections while favouring those that maxi…
More Than (Single) Text Comprehension? – On University Students’ Understanding of Multiple Documents
2020
The digital revolution has made a multitude of text documents from highly diverse perspectives on almost any topic easily available. Accordingly, the ability to integrate and evaluate information from different sources, known as multiple document comprehension, has become increasingly important. Because multiple document comprehension requires the integration of content and source information across texts, it is assumed to exceed the demands of single text comprehension due to the inclusion of two additional mental representations: the integrated situation model and the intertext model. To date, there is little empirical evidence on commonalities and differences between single text and mult…
Reviewing the impact of problem structure on planning: a software tool for analyzing tower tasks.
2010
Cognitive, clinical, and neuroimaging studies on planning abilities most frequently implement the Tower of London task or one of its variants. Yet, cumulating evidence from a series of experiments suggests that the commonly used approximation of problem difficulty in terms of the minimum number of moves for goal attainment is too coarse a measure for the underlying cognitive operations, and in some cases may be even misleading. Rather, problem difficulty can be more specifically characterized by a set of structural task parameters such as the number and nature of optimal and suboptimal solution paths, the required search depths, the patterns of intermediate and goal moves, goal hierarchies …
