A Administração Financeira surge no início do século XIX juntamente com o movimento de consolidação das grandes empresas e a formação dos mercados nacionais americano enquanto que no Brasil os primeiros estudos ocorrem a partir da segunda metade do século XX. Desde entãoo país conseguiu consolidar alguns centros de excelência em pesquisa, formar grupo significativo de pesquisadores seniores e expandir as áreas de pesquisa no campo, contudo, ainda são poucos os trabalhos que buscam retratar as características da produtividade científica em Finanças. Buscando contribuir para a melhor compreensão do comportamento produtivo dessa área a presente pesquisa estuda sua produção científica, materializada na forma de artigos digitais, publicados em 24 conceituados periódicos nacionais classificados nos estratos Qualis/CAPES A2, B1 e B2 da Área de Administração, Ciências Contábeis e Turismo. Para tanto são aplicadas a Lei de Bradford, Lei do Elitismo de Price e Lei de Lotka. Pela Lei de Bradford são identificadas três zonas de produtividade sendo o núcleo formado por três revistas, estando uma delas classificada no estrato Qualis/CAPES B2, o que evidencia a limitação de um recorte tendo como único critério a classificação Qualis/CAPES. Para a Lei do Elitismo de Price, seja pela contagem direta ou completa, não identificamos comportamento de uma elite semelhante ao apontado pela teoria e que conta com grande número de autores com apenas uma publicação.Aplicando-se o modelo do Poder Inverso Generalizado, calculado por Mínimos Quadrados Ordinários (MQO), verificamos que produtividade dos pesquisadores, quando feita pela contagem direta, se adequa àquela definida pela Lei de Lotka ao nível de α = 0,01 de significância, contudo, pela contagem completa não podemos confirmar a hipótese de homogeneidade das distribuições, além do fato de que nas duas contagens a produtividade analisada pelo parâmetro n é maior que 2 e, portanto, a produtividade do pesquisadores de finanças é menor que a defendida pela teoria.

The paper presents a multicriteria decision support system, called MultiDecision-2, which consists of two independent parts - MKA-2 subsystem and MKO-2 subsystem. MultiDecision-2 software system supports the decision makers (DMs) in the solving process of different problems of multicriteria analysis and linear (continues and integer) problems of multicriteria optimization. The two subsystems MKA-2 and MKO-2 of of MultiDecision-2 are briefly described in the paper in the terms of the class of the problems being solved, the system structure, the operation with the interface modules for input data entry and the information about DM’s local preferences, as well as the operation with the interface modules for visualization of the current and final solutions.

The paper describes a learning-oriented interactive method for solving linear mixed integer problems of multicriteria optimization. The method increases the possibilities of the decision maker (DM) to describe his/her local preferences and at the same time it overcomes some computational difficulties, especially in problems of large dimension. The method is realized in an experimental decision support system for finding the solution of linear mixed integer multicriteria optimization problems.

L'Italia è spesso sede di eventi d'intensa precipitazione, frequentemente associati ad alluvioni con conseguente perdita di vite umane e gravi danni economici. È quindi di fondamentale importanza poter prevedere questi eventi con un adeguato anticipo. Allo stato attuale, i modelli meteorologici non permettono sempre di raggiungere tale obbiettivo e, di conseguenza, è in atto un'intensa attività di ricerca al fine di di renderne più accurata la previsione, sia attraverso il miglioramento dei modelli stessi, sia sviluppando l'assimilazione dati, la quale riduce l'incertezza della condizione iniziale da cui parte la previsione. All'interno di questo contesto, la tesi si prefigge l'obiettivo di studiare gli effetti dell'assimilazione di dati di precipitazione, effettuata mediante uno schema di nudging, nel modello non idrostatico MOLOCH. Al fine di ottimizzare lo schema e di valutarne l'impatto, sono stati simulati tutti gli eventi di maltempo di ottobre e novembre del 2014 che hanno interessato la Liguria, area frequentemente soggetta ad alluvioni. Dalla sistematica verifica dei risultati, effettuata sia qualitativamente che mediante numerosi metodi statistici (tra cui la tecnica SAL basata sull'individuazione dei nuclei di precipitazione), si riscontra un generale miglioramento della previsione della precipitazione anche se limitato alle prime ore dopo la fine del periodo di assimilazione. L'impatto dello schema di nudging varia a seconda dell'evento e, in particolare, si osserva una certa correlazione tra il miglioramento ottenuto e la tipologia di evento, come descritto dalla teoria dell'equilibrio convettivo e come riportato in alcuni studi analoghi recentemente comparsi in letteratura. La ricaduta del miglioramento della previsione meteorologica è stata valutata anche in termini di impatti al suolo accoppiando il modello meteorologico con il modello idrologico utilizzato dal Centro Funzionale della Regione Liguria, con risultati abbastanza positivi.

The implementation of the railway in Triângulo Mineiro and Alto Paranaíba helped to develop the area and connexion with other states: São Paulo, Goiás and Mato Grosso. The railway used to transport people and goods throughout many train stations in urban and rural areas and some major railroad complexes. There were many factors that led to the decline and abandonment of these properties: governmental policies which were in favour of road transportation and automotive industry, the replacement of the steam locomotive for electric and electric-diesel locomotives, changing part of the railway plan, removal of railways and loss of function of the buildings, extinction of passenger trains, which led the stations to lose its main purpose: people transport. 53% of the stations built inside the study area were demolished and most of them are in rural areas. There are several situations: stations on a precarious conservation state, most of them in the city s rural area, stations being used in urban and rural areas with new uses, stations working with cargo and goods transportation. The stations in Triângulo Mineiro and Alto Paranaíba area in Minas Gerais are the object of this dissertation, wherein the main interest lies on the stations that are in operation, 21 buildings, seeking to verify their conservation state, their agents and role in preserving the train memory. Maps, charts and tables were made for this collection s understanding, having visited the stations that are listed by the cultural heritage and the ones that are in operation with new functions. Field records were made allowing the understanding of these properties in operation. It is observed that only the buildings listing, despite ensuring the non-demolition, does not help on the use and preservation of these stations, because there are some buildings that have this protection level, but are abandoned and in disrepair. The use of these stations by a train company, operating with cargo and goods transportation do not also guarantee the buildings preservation, as they are not treated with any preservation interest, their maintenance are precarious. The using by these companies are various, however, only a few stations have internal spaces dedicated to the railroad memory. Most of the stations did not have preservation projects with architects and specialists participation and the major concern, during maintenance process, is on the building s external part. The stations conservation begins on the local government interest, that preserve these properties, most of them are in urban areas, the major challenge is on their using definition and occupancy, especially in the countryside, wherein the buildings uses must be sustainable, as regards the appreciation and management of this heritage.

This research objective is to analyze the historical aspects of the city ―Capela de Nossa Senhora da Piedade de Campo Formoso‖, located in the micro region Pires do Rio, southeast of Goiás in the period of the First Republic, 1989-1930. To understand a city is to try to understand the individuals who inhabit it, as they are the ones who are responsible for the structures that forms that space. Therefore this thesis brings to the historiography a study of the city of Capela de Nossa Senhora da Piedade de Campo Formoso through various mechanisms as oral sources, official documents of the municipality collected in public bodies of the city made available in town halls, municipal public and archive file of the prefecture. These sources have helped us to make the knowledge of the place approached. The Republic has brought to different places of Brazil expectations and/or solutions, of innovations that modernized in order to erase the marks the old colonial system. The cities to be created would be part of the molds republicans and this way, should follow models ready coming, basically, from European countries. However, the city of the Capela de Nossa Senhora da Piedade de Campo Formoso is outside of this process moderniser, having been relegated by several years to difficulties of a distant region and without resources. The historiography of Goiás summarizes the period of the arrival of the railroad in the southern region of the State, such as a time of progress in all the sectors of the life of this society. Then, to understand the specificity of Campo Formoso, we approached from the documentary sources exist various elements constitutor city history: its political constitution formed by the most affluent of the city, the strength of the colonels, the role of the Church as a political power. These power relations in the region were decisive for the deviation of the railroad. In this way, also we sought to analyze how the process of urbanization has occurred and which represented for the history of the city Capela de Nossa Senhora da Piedade de Campo Formoso the passage of the Railroad Goiás not within its limits. In the meantime we situate the special policies of a city in the interior of Goiás, which is on the edge of a project set up as amodernizer moved by the First Republic.
