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.

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.

The algal flora of two distinct habitats along the Moa River in the state of Acre, Brazil

Twenty-eoght algal samples were collected in September-October, 1984, from two distinct habitats in the state of Acre, Brazil. Eleven were from the Moa River, and 17 were from a sulfur water spring which flows into the Moa River. A total of 74 species, representing 48 genera of algae, were identified from these samples. Forty-nine species were found in the Moa River and 67 in the sulfur water spring. Both coolection site had rich assemblages of cyanophycean algae, chlorophycean algae, and diatoms. Chlorophycean species dominated the algae flora at both sites, cut were more numerous at the sulfur water spring. There was also a definite difference in the relatives proportions of desmids to filamentous chlorophycean algae at the two sites.

Paleogenetic and taphonomic analysis of human bones from Moa, Beirada, and Zé Espinho Sambaquis, Rio de Janeiro, Brazil

The present paper discusses mtDNA and taphonomy of human remains from Moa, Beirada, and Zé Espinho sambaquis of Saquarema, state of Rio de Janeiro, Brazil. New human bone dating by 14C-AMS for Moa archeological site (3810+50 BP - GX-31826-AMS) is included. Preservation of microscopic lamellae and DNA is not related to the macroscopic integrity of the bones. Results here suggest that the preservation of amplifiable DNA fragments may have relation to the preservation of the lamellar arrangement as indicated by optical microscopic examination (polarized light). In 13 human bone fragments from Moa, Beirada, and Zé Espinho it was possible to sequence mtDNA from the 3 individuals of Moa, and from 1 of 4 individuals of Beirada, whose bones also show extensive areas with preserved lamellar structures. The 6 human bone fragments of Zé Espinho and 3 of the 4 fragments of Beirada showed extensive destruction of cortical microstructure represented by cavities, intrusive minerals, and agglomerated microscopic bodies of fungi and bacteria; it was not possible to extract mtDNA from these samples. The results support the hypothesis that the preservation of the microscopic osteon organization is a good predictor for DNA preservation. It was also confirmed the C haplogroup antiquity in Brazil.

The use of the Family Management Style Framework to evaluate the family management of liver transplantation in adolescence

Objective: To understand the family management experience of liver transplantation during adolescence based on the Family Management Style Framework(FMSF). Method: This is a case study that used the FMSF as theoretical framework and the hybrid model of thematic analysis as methodological reference. The case presented is from an adolescent’s family that lives in Salvador, Bahia. The data were collected through interviews with the mother and the patient charts analysis. Results: The results shows that the family defines the transplantation as threatening and there are divergence between mother and daughter related to the teen’s capabilities perception. Facing those discrepancies, the family assumes a protective posture by believing that the teen cannot take care of herself alone. The perceived consequences reflect how much the uncertainty permeates the family environment. Conclusion: It is concluded that the use of a model to evaluate the management can help professionals to direct and plan specific interventions.



A mathematical framework for group analysis of von Willebrand factor multimeric composition following luminography

The objective of the present study was to establish a method for quantitative analysis of von Willebrand factor (vWF) multimeric composition using a mathematical framework based on curve fitting. Plasma vWF multimers from 15 healthy subjects and 13 patients with advanced pulmonary vascular disease were analyzed by Western immunoblotting followed by luminography. Quantitative analysis of luminographs was carried out by calculating the relative densities of low, intermediate and high molecular weight fractions using laser densitometry. For each densitometric peak (representing a given fraction of vWF multimers) a mean area value was obtained using data from all group subjects (patients and normal individuals) and plotted against the distance between the peak and IgM (950 kDa). Curves were constructed for each group using nonlinear fitting. Results indicated that highly accurate curves could be obtained for healthy controls and patients, with respective coefficients of determination (r²) of 0.9898 and 0.9778. Differences were observed between patients and normal subjects regarding curve shape, coefficients and the region of highest protein concentration. We conclude that the method provides accurate quantitative information on the composition of vWF multimers and may be useful for comparisons between groups and possibly treatments.

Dehydration of "dedo de moça" pepper: kinetics and phytochemical concentration

Red pepper is rich in vitamin C and other phytochemicals and can be consumed as a dehydrated product. The evaluation of the best drying conditions can ensure a better quality product. This study aimed to investigate the effect of air temperature (55, 65, and 75 ºC) on drying kinetics of red peppers and on vitamin C, total phenolic content, and color of dried pepper as compared to the fresh product. Dehydration was carried out in a forced convection oven. Drying kinetics was determined by periodic weighting until constant weight. The moisture content of the fresh pepper was approximately 86%. The drying curves were fitted to three different models available in the literature. The Page model showed the best fit for this process. Analysis of variance revealed that the air drying temperature significantly influenced (p < 0.05) the quality parameters (vitamin C content, total phenolic content, and color) of the dried pepper as compared to the fresh pepper. After drying, the vitamin C retention increased with reduced air-drying temperature. In general, products dried at lower temperatures exhibited better quality due to reduced losses of bioactive compounds.

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.

A framework to understand human action

This paper consists in an analysis of two explanatory models of human behaviour which play a prominent role in the contemporary literature on human action. The first model - the causalist - aims at explaining action in terms of causes and general laws. The second model - the intentionalist - explains human action in terms of intentions and practical syllogism. The difficulties of both models are presented and in the last part of the essay we propose one alternative model, based on the notion of retroduction.
