Schematic or taxonomic organisation of the reality and the development of class logic
1994
Abstract The experiment studied the effect of various methods of organising reality (taxonomic vs. schematic) on success in inclusion and logical complementation tasks. Seventy-two nine-year-old children were divided into four groups on the basis of their logical structuring abilities. Using three sets of material (Animals, Plants, Means of Transportation), the subjects performed a sorting task and an evaluation task in which the taxonomic and schematic modes of organising reality were opposed. Contrary to our hypothesis, the ″;logical included' did not exhibit a greater capacity for taxonomic organisation than the “empirical includers” of the same age, either in the sorting or the evaluati…
Design storm prediction and hydrologic modeling using a Web-GIS approach on a Free software platform
2005
Abstract The aim of this work has been to implement a set of procedures useful to automatise the evaluation, the design storm prediction and the flood discharge associated with a selected risk level. For this purpose a Geographic Information System has been implemented using Grass 5.0. One of the main topics of such a system is a georeferenced database of the highest intensity rainfalls and their assigned duration recorded in Sicily. This database contains the main characteristics for more than 250 raingauges, as well as the values of intense rainfall events recorded by these raingauges. These data are managed through the combined use of the PostgreSQL and GRASS-GIS 5.0 databases. Some of t…
Reverse engineering expert visual observations: From fixations to the learning of spatial filters with a neural-gas algorithm
2013
Human beings can become experts in performing specific vision tasks, for example, doctors analysing medical images, or botanists studying leaves. With sufficient knowledge and experience, people can become very efficient at such tasks. When attempting to perform these tasks with a machine vision system, it would be highly beneficial to be able to replicate the process which the expert undergoes. Advances in eye-tracking technology can provide data to allow us to discover the manner in which an expert studies an image. This paper presents a first step towards utilizing these data for computer vision purposes. A growing-neural-gas algorithm is used to learn a set of Gabor filters which give h…
Innoeduca : international journal of technology and educational innovation
2021
La integración de las tecnologías en el ámbito educativo es una realidad innegable en la sociedad del siglo XXI, caracterizada por los rápidos cambios que posibilitan la revolución educativa y la innovación. Muestra de ello es el uso de videojuegos en los centros escolares de las etapas de Educación Infantil y Primaria. Estas prácticas gamificadas mediante tecnología no están exentas de críticas o susceptibilidades sobre sus posibilidades educativas. Con el fin de describir los beneficios y posibilidades de la introducción de los videojuegos en las aulas detectados en la literatura científica, se ha realizado un estudio de revisión bibliográfica. Para ello, se utilizaron cuatro bases de dat…
Structural and Dynamical Complexities of Risk and Catastrophe Systems: an Approach by System Dynamics Modelling
2009
Risk and catastrophe are complex systems. Within the scope of this paper, we focus our attention on structural and dynamic complexities of catastrophes and on the possibility of modelling and simulating its double complexity with a formal and methodological framework: the General Systems Theory and System Dynamics modelling. Then we briefly propose a model of urban catastrophe related to a flood. After we propose some ways of research allowing exceeding the limits related to the modelling.
On Aggregation of Risk Levels Using T-Conorms
2019
This paper deals with solutions for numeric evaluation of risks containing several different risk factors assessed by experts. The proposed methods can be used to assess the risks and obtain the risk scores in different industries, including financial industry, but they are also suitable for assessing risks in other areas, e.g. project management. While risk is usually considered as a function of probability and impact with strong quantitative background, there are many practical cases when only qualitative risk assessment based on expert opinions can be used. At the same time there are still requirements and needs for applying numerical values and mathematical models to such qualitative as…
Project Risk Register Analysis Based on the Theoretical Analysis of Project Management Notion of Risk
2016
Abstract The aim of the current research is to examine publicly available project risk registers to find correlations between the project management theory, especially project risk management, and practical results of real project risk management – the risk registers publicly available on the Internet. In the research, the author has analysed the compliance between the theories of the project risk management described in the “Aid Delivery Methods. Volume I. Project Cycle Management Guidelines” and “Caltrans Project Risk Management Handbook, Threats and Opportunities, Second Edition, Revision 0” and the project risk registers. In the previous studies, the author concluded that after analysin…
4th International Workshop on Language Engineering (ATEM 2007)
2008
Following the great success of previous editions, ATEM2007 is the 4thedition of the ATEM workshop series. The first two editions were held with WCRE in 2003 and 2004, while the 3rdone was held with MoDELS 2006. ATEM has always been focused on engineering of language descriptions. In order to cover as many aspects of language descriptions important for greater success and adoption of model-driven engineering, ATEM has been evolving so as its scope: The first edition was about metamodelsand schemas. The second about was metamodels, schemasand grammars. The third edition was about metamodels, schemas, grammarsand ontologies.
Early Warning Systems for Food Security in West Africa: Evolution, Achievements and Challenges
2010
In West Africa, early warning systems (EWSs) for food security have been widely recognized to have contributed, in the last 20 years, to an improved ability to deal with famine emergencies. Nevertheless, despite the advancements in understanding of the environmental and socio-economic dynamics and despite the improved technologies, tackling food security remains a difficult task for decision makers as demonstrated by local food crises in many countries of the region. African Monsoon Multidisciplinary Analysis, while improving the understanding of the monsoon system, allowed us to better orient research challenges to provide EWS with improved products, effectively meeting the needs of end-us…

Sales forecasting is an essential task in retailing. In particular, consumer-oriented markets such as fashion and electronics face uncertain demands, short life cycles and a lack of historical sales data which strengthen the challenges of producing accurate forecasts. This survey paper presents state-of-the-art methods in the sales forecasting research with a focus on fashion and new product forecasting. This study also reviews different strategies to the predictive value of user-generated content and search queries.
