A Decision-Support System for the Car Pooling Problem  [PDF]
Riccardo Manzini, Arrigo Pareschi
Journal of Transportation Technologies (JTTs) , 2012, DOI: 10.4236/jtts.2012.22011
Abstract: The continuous increase of human mobility combined with a relevant use of private vehicles contributes to increase the ill effects of vehicle externalities on the environment, e.g. high levels of air pollution, toxic emissions, noise pollution, and on the quality of life, e.g. parking problem, traffic congestion, and increase in the number of crashes and accidents. Transport demand management plays a very critical role in achieving greenhouse gas emission reduction targets. This study demonstrates that car pooling (CP) is an effective strategy to reduce transport volumes, transportation costs and related hill externalities in agreement with EU programs of emissions reduction targets. This paper presents an original approach to solve the CP problem. It is based on hierarchical clustering models, which have been adopted by an original decision support system (DSS). The DSS helps mobility managers to generate the pools and to design feasible paths for shared vehicles. A significant case studies and obtained results by the application of the proposed models are illustrated. They demonstrate the effectiveness of the approach and the supporting decisions tool.
Lower bounds for sparse matrix vector multiplication on hypercubic networks
Giovanni Manzini
Discrete Mathematics & Theoretical Computer Science , 1998,
Abstract: In this paper we consider the problem of computing on a local memory machine the product y = Ax,where A is a random n×n sparse matrix with Θ(n) nonzero elements. To study the average case communication cost of this problem, we introduce four different probability measures on the set of sparse matrices. We prove that on most local memory machines with p processors, this computation requires Ω((n/p) log p) time on the average. We prove that the same lower bound also holds, in the worst case, for matrices with only 2n or 3n nonzero elements.
éTICA DE LA PRESCRIPCIóN MéDICA EN UN PAíS PAUPERIZADO
Manzini,Jorge Luis;
Acta bioethica , 2005, DOI: 10.4067/S1726-569X2005000200009
Abstract: this paper pretends to draw a brief review upon the ethical aspects of a prescription at a "micro" level, that is of the therapeutic relationship based on the georgetown "theory of principles" and on the technical aspects of a correct prescription according to the lex artis, sustained on the so-called "evidence based medicine" and on the who's requests and publications. it then turns to the subject of the medical prescription as a problem of public health. it stops at its social impact and at the undue pressures that doctors must suffer in order to prescribe, especially those coming from the pharmaceutical industry. it also offers a juridical framework focused on the human rights' international law. universal access to medication should be reached -understood as a social good of fundamental importance- in order to attain the right to sanitary assistance. several ethical justifications that hold up this right are taken into account, especially rawls' theory of justice
DECLARACIóN DE HELSINKI: PRINCIPIOS éTICOS PARA LA INVESTIGACIóN MéDICA SOBRE SUJETOS HUMANOS
Manzini,Jorge Luis;
Acta bioethica , 2000, DOI: 10.4067/S1726-569X2000000200010
Abstract: this paper consists in a particularised analysis of the declaration of helsinki, revised at the 52nd wma general assembly at edinburgh in october 2000. the framework was as follows: 1) an introduction to the subject 2) a general consideration about formal and substantial aspects of the changes 3) a detailed analysis of every modified article, be it a change or an addition; and the comparison, when appropiate, between the spanish and the english versions of the declaration. this plan was developed by means of xxv "commentaries" interpolated along the transcription of the declaration, as was available from the wma website, http://www.wma.net/s/helsinki.html, on november 28, 2000. the phrases and paragraphs analysed are identified by means of different printing characters for the modified and new pieces, and the english version. the analysis was made from a bioethical perspective, especially regarding human rights concerns, as well as considering the scientific issues of medical research, including the viewpoint of evidence based medicine. conclusions: 1) all of the amendments strengthen the declaration, advocating for higher respect for the human rights of research subjects. 2) a further revision of the formal aspects (language) of the spanish version would be advisable, because of its many punctual weaknesses and ambiguities, as compared with the english version
Roteiro pedagógico: um instrumento para a aprendizagem de conceitos de física
Manzini, Neiva Irma Jost;
Ciência & Educa??o (Bauru) , 2007, DOI: 10.1590/S1516-73132007000100008
Abstract: this investigation aims to analyze the possibilities and limits of a teaching-and-learning experience about physics subjects, carried out with students from a physics degree and its basis is in the "genetics epistemology", of jean piaget. as a methodology of teaching, it uses a pedagogical schedule, that aims to identify and promote the construction and reconstruction of cognitive processes using piaget′s perspective, aiming to make possible the comprehension of the magnitudes in physics involved in the phenomenon and logical-mathematical relations between them. i noticed that this pedagogical activity helps students in the acquisition of their knowledge and the formation of mathematical equations that expresses the physical phenomenon studied.
Tipo de conhecimento sobre inclus?o produzido pelas pesquisas
Manzini, Eduardo José;
Revista Brasileira de Educa??o Especial , 2011, DOI: 10.1590/S1413-65382011000100005
Abstract: the brazilian research on knowledge production in the field of special education began more than 15 years ago. the objective was to analyze the type of knowledge produced in the area before the methodology used in dissertations funded by the "programa de apoio a educa??o especial - proesp". the final paper analyzed referred to those projects approved by proesp within the state of s?o paulo. the analysis period was between 2004 and 2008. twenty-seven studies were found. the review was conducted through five categories: 1) studies that showed generalization and immediate application of the results, 2) research that showed immediate results for a specific group of participants, 3) descriptive research with innovative findings, 4) intervention research with innovative findings and 5) descriptive research that corroborated other studies. it was concluded that the studies advance in knowledge on inclusion and the use of some infrequent methodologies in education served as a subsidy to get the results.

Las viviendas del siglo XIX en Santiago de Chile y la región de Cuyo en Argentina
Lorena Manzini M
Universum : Revista de Humanidades y Ciencias Sociales , 2011,
Abstract: Las viviendas del siglo XIX conjugaron características materiales heredadas de la colonia como también manifestaron los cambios culturales acontecidos por la revolución de 1810 y el ingreso a la modernidad a finales del mismo siglo. Las casas fueron producto de las formas de vivir, en estrecha relación a las costumbres, los recursos materiales y económicos disponibles, junto a los saberes técnicos constructivos adquiridos hasta el momento. Las características materiales resultantes de esta relación de factores que se conjugaron en las viviendas manifestaron similitudes y diferencias tanto en Chile como en la en la región de Cuyo en Argentina. En el presente trabajo nos proponemos efectuar un estudio histórico arquitectónico sobre las características materiales de las viviendas del siglo XIX de Santiago de Chile y la Región de Cuyo Argentina en estrecha relación a las formas de vivir los espacios y costumbres, con el fin de poder comprender su significado inmerso en un marco contextual de la época que abarca a los dos países. The nineteenth century houses conjugated material properties inherited from the colony, and also expressed the cultural changes that occurred from the revolution of 1810, and the begining of the modern world at the end of the century. The houses were the product of the ways of living, closely related to the customs, the available material and financial resources, next to technical building knowledge acquired so far. The resulting material characteristics of this relationship of factors that combined in the home showed similarities and differences, both in Chile and in the region of Cuyo in Argentina. In this paper we propose to undertake an architectural history on the physical characteristics of the nineteenth century homes in Santiago de Chile and the Cuyo Region of Argentina in close relation to the lifestyles and customs, in order to understand its meaning immersed in a contextual framework for the period covering the two countries.
