O problema da motivação moral em Kant

Por que os homens são livres? No que consiste a liberdade humana? Como é possível a ação moral? Como um corpo submetido a leis naturais pode ser livre? Para responder perguntas simples como estas e outras não tão simples é que Hélio José dos Santos Souza se dedica a estudar a obra de Kant, especialmente a Fundamentação da metafísica dos costumes. Trata-se de saber se a moralidade e a ética são expressões de um princípio racional incondicionado igualmente presente nas leis imutáveis da natureza, e como é possível nos tornarmos homens melhores apesar de sermos homens. O autor apresenta ainda a discussão destes problemas por alguns dos grandes intérpretes da obra de Kant, o que enriquece filosoficamente a análise e as alternativas pertinentes. Este é um trabalho acadêmico que pode estabelecer a vocação filosófica de seus leitores: a reflexão sobre o que está em jogo é por si só um prazeroso exercício do filosofar

O problema do financiamento: uma análise histórica sobre o crédito no complexo cafeeiro paulista. Casa Branca (1874-1914)

A principal proposta desta obra é analisar as formas como a cafeicultura foi financiada na cidade paulista de Casa Branca durante um período de pleno desenvolvimento dessa cultura - final do século 19 e começo do 20 -, e as relações entre a acumulação de capitais nesse setor agrícola e a urbanização do município. O autor ampara-se em pesquisas da história econômica, baseadas nas relações que fundamentam a economia, e em áreas como a cultura e a política. Além disso, aproveita fontes documentais ainda pouco sistematizadas, como dívidas hipotecárias e penhores agrícolas, registrados em Livros Cartoriais. A obra explica como as elites ligadas à cafeicultura da região de Casa Branca centralizaram volumes consideráveis de capitais, e os investiram em grandes cidades, inclusive deixando de pagar os devidos impostos municipais. O autor estabelece um quadro da economia regional e local, com o objetivo de apreender o processo pelo qual se impediu que os recursos financeiros gerados na economia agrária de exportação se fixassem localmente. Para o professor Pedro Geraldo Tosi, que assina o prefácio, a obra é um convite aos que se interessam pela expansão e pelos desdobramentos da cultura do café e, também, os que pretendem entender melhor a importância que tiveram as cidades do interior para configuração de uma das mais instigantes metrópoles do mundo: São Paulo.

Formulações fortes para o problema de dimensionamento de lotes com várias plantas

This paper considers the multi-plant lot sizing problem. Each item can be produced in any plant and it is possible to meet the demand of a particular plant with production from one (or several) other plants, in this case, incurs a transfer cost. The objective is todevelop strong formulations for this problem. Reformulations that based on the shortest path problem and facility location problem are investigated. Finally, some computational results are presented comparing all the proposed formulations.

Considerações sobre corporeidade e percepção no último Merleau-Ponty

Our aim in this paper is to study the problem of the perception of one's own body in Merleau-Ponty's productions during the period he taught at the Collège de France. Discussions about the notion of body scheme serve as the research axis. We focus on two courses directly connected with the conceptual advances that bring Merleau-Ponty to elaborate the notion of flesh: The sensitive world and the world of expression and Nature. We particularly look into the first, as research about the diachronism in corporeity phenomena turns into theoretical support in relation to later progress. We consider that the diacritic condition of the body's position in the world is related with the theme of the circuit established between the body, the other and things. This is also related to principle of reversibility, to the body as a sensitive sentient.

Dretske e o problema dos qualia

The aim of this paper is to present and discuss Fred Dretske's (1995) suggestion for analysis of the problem of qualia. Such a problem was acknowledged following Thomas Nagel's discussion in his classical paper What is it like to be a bat. In the paper, Nagel (1974) postulates the impossibility of knowing aspects of human experience from a third-person perspective. He considers that qualitative aspects of a subject's experience, fundamental for characterization of qualia, would be lost during the course of objective descriptions of it. Based on his Representational Thesis of Mind, Dretske argues that if we were to consider mind to be the representational aspect of the brain, the nature of qualia would thus be representational. In this context, mental facts related to experiences would be representational facts: if we were to know the nature of these representational facts, we would also know the experience the system represents. Given this understanding, we discuss to what extent the Dretskean proposal constitutes (or not) an alternative for the problem of qualia.

Exposição ambiental ao chumbo: um problema de áreas contaminadas próximas a fábricas de baterias

The concentration of metal pollutants such as lead (Pb), has grown and developed in populated areas due to pollution and other human activities. Consequently, the potential for achieve this element food chain has also increased. Lead is very toxic to humans, especially to children, and exposure to lead can cause adverse health effects mainly on human nervous system, bone marrow and kidneys, interfering with chromosomal or genetic processes. This paper presents an overview of the main aspects related to environmental contamination by lead from battery plants. The assessment of an area contaminated by lead in Bauru-SP next a battery factory was reported in this work as well as the entire history of monitoring, classification and application of processes applied by CETESB since 2002. Analyzing the issue in its economic aspects, we found that the degradation of the environment is directly related to the development model adopted by the capitalist system, which is based on the law of supply and demand for products and services. The data presented indicate that Brazil still needs a broader policy where government agencies, industries and population through awareness can be united for the same purpose: to preserve life

Resolução do problema de carregamento e descarregamento de contêineres em terminais portuários via Beam Search

One problem that has been happening frequently in port terminals is the poor planning of the loading and unloading of containers. The reason of this problem is the lack of an efficient method that provides the best means of these operations. The main goal of this work is, to implement a method that provides the best ways to perform the loading and unloading of containers, at each port and thus bring a great saving for these terminals, since the number of moves is directly proportional to cost. To carry out this program was used the idea that the containers are placed in vertical stacks, where the access can be done only by the top of the stack, so the ship was treated as an matrix and to fill it, two rules were created for loading and two for unloading. To obtain the best sequence of rules was used Beam Search method, which is an enumeration type implicit method that analyzes only the best solution of the tree generated. Thus, the program developed in the Java language, provides the best way to perform the loading and unloading ports and the way as the ship leaves each port using a graphical interface

Desenvolvimento de solução para o problema de alocação de navios em berços de terminais portuários: aplicação de algoritmos genéticos e otimização por nuvens de partículas

This work proposes two optimization algorithms for the solution of the Berth Allocation Problem (PAB). Due to the economic development of the country, it became necessary for the improvement of means of transport, which mainly shipping. For this, you need a better system management port, you will receive a lot of ships carrying cargo. In this work the PAB is approached so that the goals are to reduce costs and time handling in ports. For this, we applied two computational techniques, genetic algorithms and optimization for cloud particles, to obtain the best results for this problem. The results obtained with each type of algorithm are compared to conclude which method is more efficient for the port system
