Utilizzo delle nuove tecnologie nella didattica LIM, Skype, Piattaforma e-learning e Geometria dinamica: una possibile interazione
Get PDFThe experience, built up with the students of the I M, the II M and the III M classes of the ex- "Scuola Media Antonelli - Croce", located at via Cerulli, during the Professor Caroselli’s Math and Science lessons is a direct consequence of training activities held during the earlier school years by the Professor Manuppella in the "Scuola Media B. Croce", located in Pescara, in compliance with the norms that regulated the participation of the School to the "Innovascuola" Ministerial Project
Indicators: Syntactic Vision and Semantic Vision: First Part (Indicadores: la Visión Sintáctica y la Visión Semántica: Primera Parte)
Get PDFIn this essay several aspects of the concept ‘indicator’ are criticized, as well as the technical consequences of those misconceptions. The most relevant among them is the pretence of measuring the validity of an indicator, e. g. the degree of semantic correspondence between the indicator and the concept which it is supposes to refer to.
Tradition and Modernity: Working Culture in the Western Model and Japanese Model, as an Expression of a Cultural Models. A First Reading
Get PDFIn this short article, I'll leave the application of cultural models (in the West and in Japan), which define and construct a new reality (linguistic, cultural, social, work). Through this first reading will redefine better the cultural aspect of both worlds and you will better understand the similarities and differences between the Western model (even for the synthesis made by Adriano Olivetti) and the Japanese model (which is not only a way of producing, but also is a cultural expression)
Helix-Hopes on S-Helix Matrices
Get PDFA hyperproduct on non-square ordinary matrices can be defined by using the so called helix-hyperoperations. The main characteristic of the helix-hyperoperation is that all entries of the matrices are used. Such operationscannot be defined in the classical theory. Several classes of non-square matrices have results of the helix-product with small cardinality. We study the helix-hyperstructures on the representations and we extend our study up to Lie-H_v theory by using ordinary fields. We introduce and study the class of S-helix matrices
Mathematics in Greek Civilization: Significant Current Moments (La Matematica nella Civiltà Greca: Momenti Significativi Attuali)
Get PDFThis work presents a historical excursus on the evolution of Mathematics from the Chaldean-Babylonian period (VIII-VII century BC) to the economic re-flowering in Europe (XII century AD), underlining, in particular, those aspects of science that they have influenced the development of Architecture, Astronomy and, subsequently, also the implications that are manifested in literature and political thought today. The work will be completed in a future article on the same theme dealt with in the following period, from the twelfth century to today.
Geometry and Relativity: A Reflection of History and Epistemology
No full textThis paper examines some of the foundational aspects of the relativity theory from a historical and epistemological point of view. General Relativity, in fact, establishes the identification of the space-time which is a metric varieties, therefore, "a priori" not dynamic, and matter. This distinguishes general relativity from Newtonian mechanics where space and time are absolute and therefore separable from motion and matter. The calculation on the inherent diversity, as well as all global in nature approaches that are independent of the choice or change of local coordinates are therefore suitable for the description of this theory, and they represent the most significant mathematical legacy of the Theory of Relativity itself. Geometria e Relatività: Una riflessione fra Storia ed EpistemologiaIl presente lavoro analizza alcuni aspetti fondazionali della teoria della relatività da un punto di vista storico ed epistemologico. La Relatività Generale, infatti, stabilisce l’identificazione tra lo spazio-tempo che è una varietà metrica , quindi, “a priori”, non dinamica, e la materia. Ciò distingue la Relatività Generale dalla meccanica newtoniana dove lo spazio e il tempo sono invece assoluti e, pertanto, separabili dal moto e dalla materia. Il calcolo intrinseco sulle varietà, così come tutti gli approcci di natura globale che sono indipendenti dalla scelta o dal cambiamento delle coordinate locali sono quindi adatti per la descrizione di questa teoria ed essi rappresentano l’eredità matematica più significativa della Teoria della Relatività stessa.Parole Chiave: Varietà n-dimensionali; Spazio curvo di Riemann; equazioni di campo
New epistemological perspectives for the global economy
No full textEconomics, traditionally based on the concept of exchange value, reduce the substance of the economy to the market alone, and proceeding according to deterministic-reductionist principles. The results produced by them are suffering from paradoxes and fail often their goal in the global world and highly technologized. We propose a new holistic perspective in which to object economy are assumed complex equilibrium conditions for the maintenance and evolution of life on the planet.Nuove prospettive epistemologiche per l'economia globaleLe scienze economiche, tradizionalmente fondate sul concetto di valore di scambio, riducono l'oggetto dell'economia al solo mercato e procedono secondo principi deterministico-riduzionisti. I risultati da esse prodotte sono affetti da paradossi e falliscono spesso il loro obiettivo nel mondo globale e altamente tecnologizzato. Si propone una nuova prospettiva olistica in cui ad oggetto dell'economia siano assunte le complesse condizioni di equilibrio atte al mantenimento e all'evoluzione della vita sul pianeta.Parole Chiave: epistemologia delle scienze economiche
Modellizzazione dei sistemi complessi: un’introduzione metodologica
Get PDFWe propose a methodological introduction in modeling dynamical systems for didactical aims. Firstly, we recall the deterministic paradigm in the description of natural phenomena, typical of classical physics and mathematically described by using differential equations. With the discovery of the deterministic chaos, the randomness of the motion is accepted and the description of phenomena is performed using stochastic differential equations. Finally, a special attention is devoted to the case of complex systems
Some Improved Mixed Regression Estimators and their Comparison when Disturbance Terms follow Multivariate T-Distribution
Get PDFThe Mean square error matrices, bias vector and risk functions of proposed improved mixed regression estimators are obtained by employing the small disturbance approximation technique under the condition, when disturbance terms follows multivariate t-distribution. Further, the risk function criterion is used to examine the efficiency of proposed improved mixed regression estimators
Multiple Ways of Processing in Questionnaires
Get PDFIn social sciences when questionnaires are used, there is a new tool, the bar instead of Likert scale. The bar has been suggested by Vougiouklis & Vougiouklis in 2008, who have proposed the replacement of Likert scales, usually used in questionnaires, with bar. This new tool, gives the opportunity to researchers to elaborate the questionnaires in different ways, depending on the filled questionnaires and of course on the problem. Moreover, we improve the procedure of the filling the questionnaires, using the bar instead ofLikert scale, on computers where we write down automatically the results, so they are ready for research. This new kind of elaboration is being applied on data obtained by a survey, studying the new results. The hyperstructure theory is being related with questionnaires and we study the obtained hyperstructures,which are used as an organized device of the problem and we focus on special problems
