14. The influence of shared mental models between the CIO and the Top Management Team on the strategic alignment of Information Systems: a comparison between brazilian and US companies
The gap in the understanding between the chief information officer (CIO) and the management team (TMT) has been cited as a contributing factor to their often troubled relationship. The objective of this study is to examine the development of shared mental models (SMMs) between the CIO and TMT about the role of information systems in the organization. An SMM

15. Planejamento, síntese e avaliação da atividade anti-T. cruzi de derivados furfurilidênicos com estruturas azometínica e oxadiazolínica / Design, synthesis, identification and anti-Trypanosoma cruzi activity evaluation of furfurylidene azomethine and oxadiazole derivatives
The search for alternative therapies for the treatment of Chagas disease presents great importance, since there are only two currently available drugs, nifurtimox and benznidazole. Both have considerable adverse effects and, in Brazil, is used only benznidazole. Nitro-heterocyclic compounds with activity against Trypanosoma cruzi, the causative agent of Chag

16. Sensoriamento remoto aplicado à análise temporal da relação uso da terra/temperatura e albedo de superfície na bacia do Rio Vieira no Norte de Minas Gerais
This study aimed to analyze with the help of TM data - Landsat 5, the relationship between the changes in land use and the variation of temperature and surface albedo, during period winter in basin River Vieira for the years 1985, 1995 and 2010. The choice of river basin Vieira is justified because this area, located in the North of Minas Gerais, was the sce

17. Conduits of innovation or imitation?assessing the effect of alliances on the persistence of profits in U.S. firms
This paper examines if a firm's alliances affect the persistence of its financial performance. The literature suggests two conflicting views concerning this effect. In particular, access to resources and innovation and the risk of imitation from alliances can have different impacts on performance. In our empirical analysis, based on a panel of 509 firms cove

18. Perda de valor das empresas listadas na Bovespa durante a crise financeira de 2008: uma análise sob a perspectiva da modelagem hierárquica linear / Decline in stock prices of firms listed in Bovespa during the 2008 financial crises: an analysis from the perspective of the Hierarchical Linear Modeling
Raros autores estudam as características das empresas e dos seus setores de atuação na explicação dos retornos das ações em períodos exclusivamente de crise. A escassez de trabalhos em períodos de crise pode ser considerada uma importante lacuna na literatura acadêmica, tendo em vista que as perdas são substanciais nestes períodos. O objetivo do

19. Estrutura hierárquica na resposta das distribuições geográficas de plantas do Cerrado à mudanças climáticas / Hierarchical structure in the response of geographic distributions of Cerrado plants to climate change
The climate can be considered an extremely important factor in vegetation distribution and its characteristics in a global context. Climate changes affect the global distribution of vegetation in the distant past and probably will affect in the future. Spatial distribution models of species (SDMs), also known as niche models are one of the best current tools

20. The relationship between manufacturing integration and performance from an activity-oriented perspective
Manufacturing integration with other functional areas and suppliers is a key aspect for achieving sustainable competitive advantage. The objective of this study is to analyze manufacturing integration from an activity-based perspective. We hypothesize that manufacturing integration with suppliers, marketing, and R&D is positively related to profit and sales

21. Modelos não-lineares para dados longitudinais provenientes de experimentos em blocos casualizados abordagem bayesiana / Nonlinear models for longitudinal data from experiments in randomized block design a bayesian framework
Data consisting of repeated measurements taken on each of a number of individual arise commonly in agricultural and biological applications. Modeling data of this kind usually involves the characterization of the relationship between the measured response and covariate. In many application,the proposed systematic relationship between the measured response is

23. Caminhadas determinísticas em redes complexas aplicadas em visão computacional / Determinist walks on complex applied in computer vision
Complex networks have received a growing interest in several areas of knowledge. This growth is mainly due to its flexibility in modeling and simulating topological structures that appear in our daily life. In most cases, complex networks characterization are based on basic measurements such as average degree, hierarchical degree, clustering coefficient, amo

24. Efeitos hierárquicos na margem Ebitda: influências do tempo, firma e setor. / Hierarchycal effects in the EBITDA margin: influences of time, firm and industry
Esta pesquisa explorou a controvérsia existente entre o meio empresarial e o meio acadêmico no tocante à utilização do EBITDA. Alguns autores acadêmicos apontam que este indicador tem pouca utilidade a não ser para comparar empresas de um mesmo segmento; por outro lado, o meio empresarial, utiliza fortemente o indicador para vários propósitos. Esta
