From the viewpoint of adaptability, we classify software systems as being nonreflexive, introspective and adaptive. Introducing a simple example of LL(1) languages for expressions, we present its nonreflexive and adaptive implementation using Haskell functional language. Multiple metalevel concepts are an essential demand for a systematic language approach, to build up adaptable software systems dynamically, i.e. to evolve them. A feedback reflection loop from data to code through metalevel data is the basic implementation requirement and the proposition for semi-automatic evolution of software systems. In this sense, practical experiment introduced in this paper is related to the base level of language, but it illustrates the ability for extensions primarily in horizontal but also in vertical direction of an adaptive system.

Resumo: A gênese do número em crianças é um estudo que merece destaque quando tratamos da linguagem matemática nos anos iniciais, visto que a não compreensão deste conceito remete a dificuldades de aprendizagem na área da matemática. Sendo assim, entendemos que este estudo pode contribuir para a prevenção e para a intervenção de educadores no intuito de minimizar essas dificuldades. Este estudo busca responder ao seguinte questionamento: “O que garante dizer que uma criança, ao contar verbalmente uma sequência numérica, tenha de fato constituída a noção do número?” Através dos estudos realizados por Piaget, procuramos abordar alguns pontos que devam ser considerados pelos educadores, a fim de responder a este questionamento. Para isso, apresentamos um experimento prático que visa compreender as noções de conservação de quantidades contínuas. Em seguida, detalhamos a análise quanto às possíveis respostas dos sujeitos e aos três diferentes níveis de pensamento descritos por Piaget e Szeminska (1971). Por fim, discutimos sobre as implicações que a não compreensão do número acarreta no ensino e na aprendizagem de matemática nos anos iniciais do ensino fundamental. De fato, o que se observa é que a não compreensão do número por parte das crianças pode vir a interferir em toda sua trajetória de aprendizagem matemática. Palavras-chave: Epistemologia Genética.

Thus, we understand that this study can contribute to the the intervention of educators in order to minimize these difficulties. This study seeks to answer the following question: “What guaranties saying that a child when verbally counting a numeric sequence has in fact the notion of the number constituted?” Through the studies conducted by Piaget, we seek to address a few pointers that should be considered by educators, in order to answer to this question. For such, we present a practical experiment which aims to comprehend the notions of conservation of continuous quantities. Afterwards, we detail the analysis as to the possible answers from the subjects and the three different thinking levels described by Piaget and Szeminska (1971). Lastly, we discuss the implications that the non understanding of the number cause on the teaching and the learning of mathematics in the early years of the basic education. Indeed, what is observed is that the non understanding of the numbers by part of the children may interfere in the whole of their mathematical learning. Keywords: Genetic Epistemology. Mathematics.

Abstract The paper deals with the performance testing of web mapping services. The paper describes map service tests in which it is possible to determine the performance characteristics of a map service, depending on the location and scale of the map. The implementation of the test is tailored to the Web Map Service specifications provided by the Open Geospatial Consortium. The practical experiment consists of testing the map composition acquired from OpenStreetMap data for the area of southwestern Slovakia. These tests permit checking the performance of services in different positions, verifying the configuration of services, the composition of a map, and the visualization of geodata. The task of this paper is to also highlight the fact that it is not sufficient to only interpret a map service performance with conventional indicators. A map service’s performance should be linked to information about the map’s scale and location.

Engineering education process is heavily relying on the practical hands-on experimentation. However, todayâ??s education is involving more and more e-learning aspects and learners expect to get most of the content and activity available over the Internet. Practical experiments is not trivial to carry out over the Internet, but using novel ICT technologies and integrated solution, it is possible to offer real experimentation over the Internet. This paper describes and presents the remote practical experiment system in robotic and embedded system domain.

Attentive observers of conditions in Italy are well aware that Fascism is an exceedingly complicated phenomenon; that what seems to be simply a dictatorship of the upper classes in reality presents many surprising and apparently contradictory features. Fascism, indeed, has been likened to a great river into which numerous tributaries have poured their waters. Among these tributaries are such movements as Nationalism, Futurism, and Syndicalism. Besides, Fascism is more than a practical experiment in government. It has developed a theory and a philosophy, and, one may even add, an art, a mysticism, and a religion. “Fascism,” declares Mussolini, “has a doctrine, or, if you will, a philosophy with regard to all the questions which beset the human mind today.” And again he remarks, “We play upon every chord of the lyre, from violence to religion, from art to politics.”The stages in the outward history of Fascism need only be mentioned. The movement had humble and, its enemies say, even sordid beginnings. The first Fascio di Combattimento was formed in March, 1919, by Mussolini and other derelicts of the war. This organization, swollen by all sorts of unexpected accretions, was transformed into the National Fascist party in November, 1921. In October, 1922, occurred the sensational march on Rome, which placed the party exultantly, but none too securely, in the seat of power. The murder of Matteotti in May, 1924, precipitated a dangerous crisis in which Fascism appeared to be momentarily on the defensive, but from which it triumphantly emerged as complete master of the situation. Since then it has effectually quelled all opposition and has proceeded to the realization of its constructive program, of which the great Labor Charter of April, 1927, is thus far the most impressive item.
