Otimização de fluxo em redes na gestão financeira do caixa: aplicação em uma empresa do setor agroindustrial
(Universidade Federal de São Carlos, 2007-12-18) Pacheco, José Vinícius de Avila; Morabito Neto, Reinaldo
Cash flow management is a financial problem that involves the efficient management of cash, short-term investments and short-term loans. In this study, we formulate the cash flow problem encountered in a typical agro-industrial company as a network optimization problem. Two examples using a linear programming model were studied: in the first example, the original model were used to support operational cash flow decisions, in the second example, the model were extended to a tactical planning of loan payments. The mathematic models are resolved in the solver tool that is an add-in of Microsoft Excel. Spreadsheets are of wide applicability for analytical work in business. The model has the potential of being flexible and to maximize the cash return from the final planning period in real-life situations

(Universidade Federal de São Carlos, 2007-12-18) Joly, Maria Carolina Leme; Montrone, Aida Victoria Garcia; https://lattes.cnpq.br/9011731777978672; https://lattes.cnpq.br/8669536548912329
This work is the result of a research for Masters, which aims to highlighting and analyzing the educational processes present in a community orchestra from the practice of social coexistence of a group of musicians. The Experimental Orchestra of UFSCar (São Carlos Federal University), where the data collection happened is formed by amateur and professional musicians, from different communities, with different degrees of development and musical knowledge. The theoretical reference adopted is based on works of Paulo Freire, Ernani Fiori, Moacir Gadotti, Agnes Heller, Maria Waldenez Oliveira, as well as others related to Social Practice and Educational Processes fields. Concerning Musical Education, works of Viviane Beineke, Teca Brito, Vanda Freire, Marisa Fonterrada, Carlos Kater, Hans Koellreuter, were adopted among others. This study qualifies as qualitative research with participant observation and the data were collected by semi-structure interviews with five orchestra participants. From the analysis of the data it was possible to highlight some musical, human and social living processes which happen through living in diversity such as respect for differences, tolerance, friendship, solidarity and others
Proposta de tratamento da variável localização em modelos inferenciais de avaliação imobiliária para municípios médios
(Universidade Federal de São Carlos, 2007-12-18) Ferreira, Jose Fabricio; Röhm, Sergio Antonio; https://lattes.cnpq.br/7332654261230826; https://lattes.cnpq.br/1760837109572662
Location is a central variable in mathematical models of real estate appraisal. The main goal of this dissertation is to propose a method for the treatment of this variable in a specific kind of appraisal, but very relevant, known as PGV (in Brazil, anything like an assessment roll). Besides being a important instrument of urban tax policies, PGVs also have their usefulness in urban planning for revealing the dynamics of real estate valuation. The study focuses in São Carlos (São Paulo State, Brazil), a city of nearly 210.000 inhabitants. It is a city of intermediary size, whose spatial patterns of real estate valuation are not quite simple, like in small towns, but factors whose effects have maximum expression in the metropolitan environment start to consolidate. The main of them is segregation, and the conditions of competition for the best location occur in the field of real estate market. This study aims to explore the amplitude of the city, with its variability of characteristics, incorporating in the object of study the locations of the urban core and expansion areas. It discusses the influence or correlation of factors such as demand for public services, infrastructures, attributes of location, neighbourhood aspects, urban amenities and aspects of illegality in the composition of the market value of these properties. Thus, diversity and variability of characteristics widen the study of the valuation pattern of the urban land. The innovative approach of this study is to link two fields of knowledge apparently distincts the inferential methodologies of mass evaluation and the studies of intra-urban location. The common potencial issue is tax application. It means, to the local governments, to consider the city as it shows itself, ensuring not only the success in evaluative formulations, but the respect for the principles of fairness that should characterize the tax policies.
O desempenho institucional do Executivo no Legislativo entre 2002 e 2006
(Universidade Federal de São Carlos, 2007-12-18) Santos, Rodrigo dos; Noronha, Eduardo Garuti; https://lattes.cnpq.br/6908348693613769; https://lattes.cnpq.br/7131788186272876
This master thesis analyses the interplay of political powers in Brazilian Legislative chambers, during Lula s government. It considers the point of view of the parties and the interests present on budget and fiscal disputes between Federal Executive power and State Executive powers. It is considered that, as a representative and supervisory institute, the Legislative chambers offer the possibility of politic interactions between Executive power, governors and parties. The analysis follows eight budget initiatives, being four of Crédito Extraordinário (Extraordinary Credit) and four of Auxílio Financeiro (Financial Aid), made through Medidas Provisórias (Provisory Measures) by the Executive power in benefit of States, towns and cities, after some partial constitutional modifications, known as the Amendment n° 32, were implemented. After the identification of the gaps existing both in studies that stress the centralization of legislative works and studies that emphasize the individual and regional members of parliament s behavior, this study stresses the need for initiatives of the Executive power that consider the tributary increase of other government instances. It is argued that the Executive can, strategically, co-ordinate his initiatives with the other government instances in an interactive way, to strengthen the Federal Government and to promote modifications in the current model of fiscal exaction. The analysis of the data shows that the Executive power, in spite of assuming the need for a reformulation of the fiscal model, avoids the influence of the Legislative power, particularly that of the Senate, driving bigger resources for Crédito Extraordinário, in detriment of Auxílio Financeiro. It concludes that the difficulties found by the Executive power to approve a new model of fiscal exaction in the Legislative chambers can be associated with little influence of the government party (PT) on state governments.
