The Banco Central do Brasil's institutional framework after ten years

The Banco Central do Brazil (BACEN) adopted inflation targeting in 1999. This monetary policy regime originates in institutional design which remains crucial today for the expectations management, and is in permanent evolution. After 10 years, the BACEN institutional framework is assessed, asking if there is still room for improvement. Various institutional procedures are analysed, and lessons are drawn from the international experience of a panel of sixteen countries. Some proposals for the BACEN institutional framework are made.

Fatores visuais de design e sua influência nos valores de compra do consumidor

Este artigo explora o tema das experiências dos consumidores nos ambientes físicos oferecidos pelas empresas de serviços, avaliando o impacto de fatores visuais de design sobre a percepção de valor por parte dos clientes de um ponto de venda com autosserviço. Foram identificados os valores de compra dos usuários e as características de design percebidas no âmbito do varejo de autosserviço, envolvendo leiaute, sinalização e iluminação presentes no ambiente. O valor de compra, considerado uma resposta interna do consumidor ao ambiente de varejo, incluiu dimensões utilitárias e hedônicas. O método aplicado foi o cross-sectional survey, com a aplicação de questionário a 274 estudantes universitários, os quais manifestaram sua percepção de três diferentes livrarias com autoatendimento, ilustradas por fotos. Os resultados obtidos apontaram quatro características de design com influência significativa na formação de valor de compra dos consumidores sob a perspectiva utilitária e hedônica.

USE AND CONSEQUENCES OF PARTICIPATORY GIS IN A MEXICAN MUNICIPALITY: APPLYING A MULTILEVEL FRAMEWORK

This paper seeks to understand the use and the consequences of Participatory Geographic Information System (PGIS) in a Mexican local community. A multilevel framework was applied, mainly influenced by two theoretical lenses – structurationist view and social shaping of technology – structured in three dimensions – context, process and content – according to contextualist logic. The results of our study have brought two main contributions. The first is the refinement of the theoretical framework in order to better investigate the implementation and use of Information and Communication Technology (ICT) artifacts by local communities for social and environmental purposes. The second contribution is the extension of existing IS (Information Systems) literature on participatory practices through identification of important conditions for helping the mobilization of ICT as a tool for empowering local communities.

Ensuring dynamic strategic fit of firms that compete globally in alliances and networks: proposing the Global SNA - Strategic Network Analysis - framework

In order to sustain their competitive advantage in the current increasingly globalized and turbulent context, more and more firms are competing globally in alliances and networks that oblige them to adopt new managerial paradigms and tools. However, their strategic analyses rarely take into account the strategic implications of these alliances and networks, considering their global relational characteristics, admittedly because of a lack of adequate tools to do so. This paper contributes to research that seeks to fill this gap by proposing the Global Strategic Network Analysis - SNA - framework. Its purpose is to help firms that compete globally in alliances and networks to carry out their strategic assessments and decision-making with a view to ensuring dynamic strategic fit from both a global and relational perspective.

Reflexões para um framework da informação de custos do setor público brasileiro

O presente artigo sumariza uma proposta de framework da informação de custos para o setor público no Brasil. A proposta emergiu de contribuições promovidas pelo governo central no Brasil na realização de duas equipes de trabalho, a primeira pela comissão interministerial em 2005, e a segunda coordenada pelo Ministério da Fazenda em 2008/09. Essas contribuições foram validadas em relação às críticas veiculadas no meio acadêmico quanto às estruturas conceituais da contabilidade financeira (framework) emitidas pelo International Accounting Standards Board e Financial Accounting Standards Board, e em relação à literatura internacional de implantação de sistemas de custos no setor público. A adoção de um sistema de custos é exigida para as entidades públicas no Brasil desde 1964; entretanto, somente agora é objeto de um trabalho conduzido pelo Ministério da Fazenda para o governo federal, cujos primeiros resultados serão divulgados neste ano. O acórdão emitido pelo Tribunal de Contas da União em 2004, determinando que a legislação seja observada, tende a ampliar tal adoção. Contudo, a adoção não é suficiente, é necessária a utilização, que é função da relevância percebida da informação de custos. Sugere-se que a difusão da adoção e uso de sistemas de custos no setor público brasileiro seja feita através de uma implantação gradual, flexível, mediante a adoção do regime de competência, e baseada num framework único e comum às diversas entidades.

Capacidades dinâmicas e rituais de interação entre alta e média gerência: proposta de um framework

O presente artigo foi desenvolvido considerando situações de incerteza ambiental, em que a ordem do dia ou questão estratégica (strategic issue) é a inovação dos recursos, ou seja, transformação, renovação ou desenvolvimento de uma nova capacidade funcional (ordinária). Com o objetivo de compreender como as capacidades dinâmicas desempenham esse papel na inovação dos ativos organizacionais em tais contextos ambientais, propõe-se aqui uma perspectiva alternativa de análise a partir de uma vertente microssociológica, a qual recorre aos elementos constitutivos de rituais de interação segundo Collins (2004). Essa perspectiva oferece possibilidades de investigação da influência das conversações estratégicas, que ocorrem em meio a práticas ritualísticas de interação entre alta e média gerência, sobre o potencial de inovação das capacidades organizacionais. Para compreensão da articulação teórica realizada no trabalho, apresenta-se um framework de análise que agrega a incerteza no nível macro com variáveis comportamentais e organizacionais no nível micro, enquanto elementos mais salientes dos rituais de interação. Visando estudos futuros e melhor compreensão do framework do trabalho, são apresentadas proposições acerca das relações do modelo após o detalhamento da estrutura analítica.

Child-care attendance and common morbidity: evidence of association in the literature and questions of design

Papers on child-care attendance as a risk factor for acute respiratory infections and diarrhea were reviewed. There was great variety among the studies with regard to the design, definition of exposure and definition of outcomes. All the traditional epidemiological study designs have been used. The studies varied in terms of how child-care attendance in general was defined, and for different settings. These definitions differed especially in relation to the minimum time of attendance required. The outcomes were also defined and measured in several different ways. The analyses performed were not always appropriate, leading to sets of results of uneven quality, and composed of different measures of association relating different exposures and outcomes, that made summarizing difficult. Despite that, the results reported were remarkably consistent. Only two of the papers reviewed failed to show some association between child-care attendance and increased acute respiratory infections, or diarrhea. On the other hand, the magnitude of the associations reported varied widely, especially for lower respiratory infections. Taken together, the studies so far published provide evidence that children attending child-care centers, especially those under three years of age, are at a higher risk of upper respiratory infections, lower respiratory infections, and diarrhea. The studies were not consistent, however, in relation to attendance at child-care homes. Children in such settings were sometimes similar to those in child-care centers, sometimes similar to those cared for at home, and sometimes presented an intermediate risk.

BASS 4: a software system for ergonomic design and evaluation of working hours

OBJECTIVE: To extend an existing computer programme for the evaluation and design of shift schedules (BASS 3) by integrating workload as well as economic aspects. METHODS: The redesigned prototype BASS 4 includes a new module with a suitable and easily applicable screening method (EBA) for the assessment of the intensity of physical, emotional and cognitive workload components and their temporal patterns. Specified criterion functions based on these ratings allow for an adjustment of shift and rest duration according to the intensity of physical and mental workload. Furthermore, with regard to interactive effects both workload and temporal conditions, e.g. time of day, are taken into account. In a second new module, important economic aspects and criteria have been implemented. Different ergonomic solutions for scheduling problems can now also be evaluated with regard to their economic costs. RESULTS: The new version of the computer programme (BASS 4) can now simultaneously take into account numerous ergonomic, legal, agreed and economic criteria for the design and evaluation of working hours. CONCLUSIONS: BASS 4 can now be used as an instrument for the design and the evaluation of working hours with regard to legal, ergonomic and economic aspects at the shop floor as well as in administrative (e.g. health and safety inspection) and research problems.

Payment for performance in the Family Health Programme: lessons from the UK Quality and Outcomes Framework

OBJECTIVE: Payment for performance financial incentive schemes reward doctors based on the quality and the outcomes of their treatment. In Brazil, the Ministry of Health is looking to scale up its use in public hospitals and some municipalities are developing payment for performance schemes even for the Family Health Programme. In this article the Quality and Outcomes Framework used in the UK since 2004 is discussed, as well as its experience to elaborate some important lessons that Brazilian municipalities should consider before embarking on payment for performance scheme in primary care settings.
