Inflação de serviços no Brasil: pressão de demanda ou de custos?

A persistência da inflação de serviços no Brasil entre 2005 e 2013, e forte alteração do preço relativo entre preços de serviços e preços de comercializáveis coincidiu temporalmente com forte aumento da renda nominal da população e queda do desemprego. Esta dissertação tem como objetivo identificar os fatores que foram mais importantes na formação dos preços dos serviços e se os salários contribuíram para a aceleração dos preços através do aumento de custos no setor ou através do aumento da demanda por estes itens. A partir de um modelo VAR com variáveis exógenas de controle para custos e para a demanda, o estudo conclui que as pressões de custo foram mais importantes para explicar o comportamento da inflação de serviços no Brasil no período considerado.

A abordagem da capacitação como um modelo alternativo à nova administração pública para as ações estatais : um estudo de caso das políticas públicas dos municípios de Tupandi, Torres e Porto Alegre

Esta tese tem o objetivo de evidenciar a troca de prioridades na formulação de políticas públicas imposta pelas novas pressões e desafios sofridos pelo Estado, bem como pelas demandas e expectativas por parte da sociedade civil concernentes a uma agenda política voltada para questões de justiça, eqüidade e gastos públicos voltados para as necessidades dos cidadãos. Essa investigação fundamenta-se na limitação da abordagem que está na base do processo de reforma seguido pelo Estado a partir da década de oitenta. Conforme o paradigma subjacente (Nova Administração Pública), no processo de reforma, as ações governamentais e, portanto, a definição de políticas públicas, se reduzem a fins utilitários, focados na renda e na obtenção da maximização de resultados quantitativos. No entanto, o novo cenário exige uma ampla demanda por respostas estatais, cujas ações, através das políticas públicas, não podem ser voltadas apenas para a eficiência, mas, também para a eqüidade governamental. Dessa forma, toma-se necessário avançar em direção a um modelo que fundamente as ações estatais - elaboração e implementação de políticas públicas - que considere outras dimensões relevantes além da dimensão econômica. Para tanto, apresenta-se a Abordagem da Capacitação como um modelo alternativo para as ações governamentais mais recentes, preocupadas com a eficiência e a eqüidade. Assim, empregando o estudo de casos múltiplos e a técnica qualitativa de análise descritiva-interpretativa, foi verificado se as políticas públicas dos municípios estão incorporando questões mais relacionadas com a Abordagem da Capacitação, em comparação com aspectos mais instrumentais, como sugere o modelo da Nova Administração Pública. Como resultado, foi constatado que, de modo geral, todos os municípios pesquisados estão incluindo outros aspectos além da eficiência na elaboração de suas políticas públicas e, portanto, estão incorporando questões mais relacionadas com a Abordagem da Capacitação, em comparação com aspectos mais instrumentais, como sugere o modelo da Nova Administração Pública. Diante dessa constatação e dadas as limitações referentes ao modelo da Nova Administração Pública observadas nos casos de Tupandi e de Porto Alegre com respeito ao modelo de gestão implícito e da insuficiência do foco em questões administrativas e gerenciais no desenvolvimento das políticas para tratar problemas atuais verificada em todos os casos, conclui-se que as políticas públicas dos três municípios analisados estão seguindo uma intuição da Abordagem da Capacitação e, dessa forma, esse paradigma proposto representa melhor as ações governamentais mais recentes, preocupadas com a eficiência e a eqüidade, servindo, assim, como um modelo alternativo à Nova Administração Pública para as ações estatais.

Social media crises in the organization: exploring management strategies through cases from France and Brazil

The aim of this Master’s thesis has been to shed light on the response strategies that organizations are implementing when facing a crisis created on or amplified by social media. Since the development of social media in the late 1990s, the interplay between the online and the offline spheres has become more complex, and characterized by dynamics of a new magnitude, as exemplified by the wave of “Twitter” Revolutions or the Wikileaks scandal in the mid 2000s, where online behaviors deeply affected an offline reality. The corporate world does not escape to this worldwide phenomenon, and there are more and more examples of organizational reputations destroyed by social media “fireballs”. As such, this research aims to investigate, through the analysis of six recent cases of corporate crises (2013-2015) from France and Brazil, different strategies currently in use in order to identify examples of good and bad practices for companies to adopt or avoid when facing a social media crisis. The first part of this research is dedicated to a review of the literature on crisis management and social media. From that review, we were able to design a matrix model, the Social Media Crisis Management Matrix, with which we analyzed the response strategies of the six companies we selected. This model allows the conceptualization of social media crises in a multidimensional matrix built to allow the choice, according to four parameters, of the most efficient (that is: which will limit the reputational damage) response strategy. Attribution of responsibility for the crisis to the company by stakeholders, the origin of the crisis (internal or external), the degree of reputational threat, and the emotions conveyed online by stakeholders help companies determining whether to adopt a defensive response, or an accommodative response. The results of the analysis suggest that social media crises are rather manichean objects for they are, unlike their traditional offline counterparts, characterized by emotional involvement and irrationality, and cannot be dealt with traditionally. Thus analyzing the emotions of stakeholders proved to be, in these cases, an accurate thermometer of the seriousness of the crisis, and as such, a better rudder to follow when selecting a response strategy. Consequently, in the cases, companies minimized their reputational damage when responding to their stakeholders in an accommodative way, regardless of the “objective” situation, which might be a change of paradigm in crisis management.

A gestão da informação sob a luz do Enterprise Content Management (ECM): um estudo de caso em uma universidade pública

This work involves the organization and content perspectives on Enterprise Content Management (ECM) framework. The case study at the Federal University of Rio Grande do Norte was based on ECM model to analyse the information management provided by the three main administrative systems: The Integrated Management of Academic Activities (SIGAA), Integrated System of Inheritance, and Contracts Administration (SIPAC) and the Integrated System for Administration and Human Resources (SIGRH). A case study protocol was designed to provide greater reliability to research process. Four propositions were examined in order to reach the specific objectives of identification and evaluation of ECM components from UFRN perspective. The preliminary phase provided the guidelines for the data collection. In total, 75 individuals were interviewed. Interviews with four managers directly involved on systems design were recorded (average duration of 90 minutes). The 70 remaining individuals were approached in random way in UFRN s units, including teachers, administrative-technical employees and students. The results showed the presence of many ECM elements in the management of UFRN administrative information. The technological component with higher presence was "management of web content / collaboration". But initiatives of other components (e.g. email and document management) were found and are in continuous improvement. The assessment made use of eQual 4.0 to examine the effectiveness of applications under three factors: usability, quality of information and offered service. In general, the quality offered by the systems was very good and walk side by side with the obtained benefits of ECM strategy adoption in the context of the whole institution

Avaliação de impacto ambiental e gestão dos recursos natuarias no estuário Apodi Mossoró, nordeste do Brasil

The aim of this study is to investigate the eco-environmental vulnerability, its changes, and its causes to develop a management system for application of eco-environmental vulnerability and risk assessment in the Apodi-Mossory estuary, Northeast Brazil. This analysis is focused on the interference of the landscape conditions, and its changes, due to the following factors: the oil and natural gas industry, tropical fruits industry, shrimp farms, marine salt industry, occupation of the sensitive areas; demand for land, vegetation degradation, siltation in rivers, severe flooding, sea level rise (SLR), coastal dynamics, low and flat topography, high ecological value and tourism in the region and the rapid growth of urbanization. Conventional and remote sensing data were analyzed using modeling techniques based on ArcGIS, ER-Mapper, ERDAS Imagine and ENVI software. Digital images were initially processed by Principal Component Analysis and transformation of the maximum fraction of noise, and then all bands were normalized to reduce errors caused by bands of different sizes. They were integrated in a Geographic Information System analysis to detect changes, to generate digital elevation models, geomorphic indices and other variables of the study area. A three band color combination of multispectral bands was used to monitor changes of land and vegetation cover from 1986 to 2009. This task also included the analysis of various secondary data, such as field data, socioeconomic data, environmental data and prospects growth. The main objective of this study was to improve our understanding of eco-environmental vulnerability and risk assessment; it´s causes basically show the intensity, its distribution and human-environment effect on the ecosystem, and identify the high and low sensitive areas and area of inundation due to future SLR, and the loss of land due to coastal erosion in the Apodi-Mossoró estuary in order to establish a strategy for sustainable land use. The developed model includes some basic factors such as geology, geomorphology, soils, land use / land cover, vegetation cover, slope, topography and hydrology. The numerical results indicate that 9.86% of total study area was under very high vulnerability, 29.12% high vulnerability, 52.90% moderate vulnerability and 2.23% were in the category of very low vulnerability. The analysis indicates that 216.1 km² and 362.8 km² area flooded on 1m and 10m in sea levels respectively. The sectors most affected were residential, industrial and recreational areas, agricultural land, and ecosystems of high environmental sensitivity. The results showed that changes in eco-environmental vulnerability have a significant impact on the sustainable development of the RN state, since the indicator is a function of sensitivity, exposure and status in relation to a level of damage. The model were presented as a tool to assist in indexing vulnerability in order to optimize actions and assess the implications of decisions makers and policies regarding the management of coastal and estuarine areas. In this context aspects such as population growth, degradation of vegetation, land use / land cover, amount and type of industrialization, SLR and government policies for environmental protection were considered the main factors that affect the eco-environmental changes over the last three decades in the Apodi-Mossoró estuary.

An easy-learning and easy-teaching tool for indoor thermal analysis - ArcTech

ArcTech is a software being developed, applied and improved with the aim of becoming an efficient sensitization tool to support the teaching-learning process of Architecture courses. The application deals initially with the thermal comfort of buildings. The output generated by the software shows if a student is able to produce a pleasant environment, in terms of thermal sensation along a 24-hours period. Although one can find the very same characteristics in fully-developed commercial software, the reason to create ArcTech is related to the flexibility of the system to be adapted by the instructor and also to the need of simple tools for the evaluation of specific topics along the courses. The first part of ArcTech is dedicated to data management and that was developed using the visual programming language Delphi 7 and Firebird as the database management system. The second part contains the parameters that can be changed by the system administrator and those related to project visualization. The interface of the system, in which the student will learn how to implement and to evaluate the project alternatives, was built using Macromedia Flash. The software was applied to undergraduate students revealing its easy-learning and easy-teaching interface.

Estudo de vibrações eólicas em linhas de transmissão de energia elétrica de alta tensão

O crescente aumento da demanda de energia elétrica tem forçado o avanço tecnológico dos equipamentos responsáveis pelo transporte desta energia fazendo com que estes trabalhem sob tensões cada vez maiores, principalmente por razões econômicas. Mas este fato implica diretamente no incremento do diâmetro do condutor, o que acarreta elevação de seus custos, bem como das estruturas que devem suportá-lo. Para atender a esta necessidade sem aumentar o custo de projeto da linha de transmissão, surgiu a idéia de utilizar mais de um condutor por fase, montados paralelamente entre si a pequenas distâncias, o que é conseguido através da inserção de espaçadores montados a intervalos regulares ao longo dos vãos das linhas. Por outro lado, problemas mecânicos de ordem operacional das linhas podem ocorrer, como, por exemplo, a ruptura total ou parcial dos cabos e/ou espaçadores, proveniente de excitações dinâmicas devidas ao vento. Assim, este trabalho consiste no estudo do comportamento dinâmico de feixe de cabos de linhas aéreas de transmissão, através de um modelo de elementos finitos. O modelo reproduz o acoplamento dos cabos aos espaçadoresamortecedores da linha de transmissão e às estruturas de ancoragem, considerando o efeito de não-linearidade geométrica, decorrente dos grandes deslocamentos dos cabos, bem como a continuidade da linha, ou seja, os vãos adjacentes, que são representados por rigidez equivalente no modelo. O carregamento de vento é modelado através de um processo não deterministico a partir de suas propriedades estatísticas, tal que fica subdividido em duas partes: uma parte média, analisada de forma estática; e uma parte variável, analisada de forma dinâmica. Os resultados obtidos ao longo desse estudo mostram que a parcela variável do carregamento leva a uma resposta dinâmica do modelo que pode ser determinante no seu comportamento. Assim, o procedimento tradicional de assumir o carregamento do vento como uma excitação estática pode levar, em alguns casos a conseqüências desastrosas.

Suitability of carbon fiber-reinforced polymers as power cable cores: Galvanic corrosion and thermal stability evaluation

The increasing demand for electrical energy and the difficulties involved in installing new transmission lines presents a global challenge. Transmission line cables need to conduct more current, which creates the problem of excessive cable sag and limits the distance between towers. Therefore, it is necessary to develop new cables that have low thermal expansion coefficients, low densities, and high resistance to mechanical stress and corrosion. Continuous fiber-reinforced polymers are now widely used in many industries, including electrical utilities, and provide properties that are superior to those of traditional ACSR (aluminum conductor steel reinforced) cables. Although composite core cables show good performance in terms of corrosion, the contact of carbon fibers with aluminum promotes galvanic corrosion, which compromises mechanical performance. In this work, three different fiber coatings were tested (phenol formaldehyde resin, epoxy-based resin, and epoxy resin with polyester braiding), with measurements of the galvanic current. The use of epoxy resin combined with polyester braiding provided the best inhibition of galvanic corrosion. Investigation of thermal stability revealed that use of phenol formaldehyde resin resulted in a higher glass transition temperature. On the other hand, a post-cure process applied to epoxy-based resin enabled it to achieve glass transition temperatures of up to 200 degrees C. (C) 2014 Elsevier Ltd. All rights reserved.

Análise da eficiência energética em indústrias madeireiras através da lógica fuzzy

This paper presents the application of fuzzy theory to support the decision of implementing energy efficiency program in sawmills operating in the processing of Pinustaeda and Pinuselliotii. The justification of using a system based on fuzzy theory for analysis of consumption and the specific factors involved, such is the diversity of rates / factors. With the fuzzy theory, we can build a reliable system for verifying actual energy efficiency. The indices and factors characteristic of industrial activity were measured and used as the basis for the fuzzy system. We developed a management system and technology. The system involves the management practices in energy efficiency, maintenance of plant and equipment and the presence of qualified staff. The technological system involves the power factor, load factor, the factor of demand and the specific consumption. The first response provides the possibility of increased energy efficiency and the second level of energy efficiency in the industry studied. With this tool, programs can be developed for energy conservation and energy efficiency in the industrial timber with wide application in this area that is as diverse as production processes. The same systems developed can be used in other industrial activities, provided they are used indices and characteristic features of the sectors involved.
