A network society communicative model for optimizing the Refugee Status Determination (RSD) procedures

This article recommends a new way to improve Refugee Status Determination (RSD) procedures by proposing a network society communicative model based on active involvement and dialogue among all implementing partners. This model, named after proposals from Castells, Habermas, Apel, Chimni, and Betts, would be mediated by the United Nations High Commissioner for Refugees (UNHCR), whose role would be modeled after that of the International Committee of the Red Cross (ICRC) practice.

The international implications of the Chinese model of development in the Global South: Asian Consensus as a network power

This paper analyzes People's Republic of China (PRC) economic and political ascendance in the 21st century focusing on the evolution of the sui generis economic development model and its significances of the evolution of relationship between China and the developing countries in the peripheral "Global South." The objective of this article is to analyze the relationship between China and the Global South (Africa and South America) in the 21st century, characterized as a new Center-periphery global network power based on trade and investment that we call as "Asian Consensus."

Network dynamics in scientific knowledge acquisition: an analysis in three public universities in the state of Bahia

This paper aims to cast some light on the dynamics of knowledge networks in developing countries by analyzing the scientific production of the largest university in the Northeast of Brazil and its influence on some of the remaining regional research institutions in the state of Bahia. Using a methodology test to be employed in a larger project, the Universidade Federal da Bahia (UFBA) (Federal University of Bahia), the Universidade do Estado da Bahia (Uneb) (State of Bahia University) and the Universidade Estadual de Santa Cruz (Uesc)'s (Santa Cruz State University) scientific productions are discussed in one of their most traditionally expressive sectors in academic production - namely, the field of chemistry, using social network analysis of co-authorship networks to investigate the existence of small world phenomena and the importance of these phenomena in research performance in these three universities. The results already obtained through this research bring to light data of considerable interest concerning the scientific production in unconsolidated research universities. It shows the important participation of the UFBA network in the composition of the other two public universities research networks, indicating a possible occurrence of small world phenomena in the UFBA and Uesc networks, as well as the importance of individual researchers in consolidating research networks in peripheral universities. The article also hints that the methodology employed appears to be adequate insofar as scientific production may be used as a proxy for scientific knowledge.

Scientific research in tourism: review of the literature from 2005 to 2009

This article presents the results of a review of the literature on tourism from 2005 to 2009. Precisely, 1,648 articles were reviewed and classified into eight macro-lines of research. The content of the Strategy macro-line was analyzed in greater depth, as it was considered to be an "umbrella" for the other dimensions pertinent to tourism. The literature thus provided significant elements confirming the appropriateness of the strategic network perspective for research on sustainable tourism management, and it also helped identify the actors that are most critical for leading the development of a tourist destination.

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.

Dynamic network data envelopment analysis for university hospitals evaluation

ABSTRACT OBJECTIVE To develop an assessment tool to evaluate the efficiency of federal university general hospitals. METHODS Data envelopment analysis, a linear programming technique, creates a best practice frontier by comparing observed production given the amount of resources used. The model is output-oriented and considers variable returns to scale. Network data envelopment analysis considers link variables belonging to more than one dimension (in the model, medical residents, adjusted admissions, and research projects). Dynamic network data envelopment analysis uses carry-over variables (in the model, financing budget) to analyze frontier shift in subsequent years. Data were gathered from the information system of the Brazilian Ministry of Education (MEC), 2010-2013. RESULTS The mean scores for health care, teaching and research over the period were 58.0%, 86.0%, and 61.0%, respectively. In 2012, the best performance year, for all units to reach the frontier it would be necessary to have a mean increase of 65.0% in outpatient visits; 34.0% in admissions; 12.0% in undergraduate students; 13.0% in multi-professional residents; 48.0% in graduate students; 7.0% in research projects; besides a decrease of 9.0% in medical residents. In the same year, an increase of 0.9% in financing budget would be necessary to improve the care output frontier. In the dynamic evaluation, there was progress in teaching efficiency, oscillation in medical care and no variation in research. CONCLUSIONS The proposed model generates public health planning and programming parameters by estimating efficiency scores and making projections to reach the best practice frontier.

ERICA: intake of macro and micronutrients of Brazilian adolescents

ABSTRACT OBJECTIVE To describe food and macronutrient intake profile and estimate the prevalence of inadequate micronutrient intake of Brazilian adolescents. METHODS Data from 71,791 adolescents aged from 12 to 17 years were evaluated in the 2013-2014 Brazilian Study of Cardiovascular Risks in Adolescents (ERICA). Food intake was estimated using 24-hour dietary recall (24-HDR). A second 24-HDR was collected in a subsample of the adolescents to estimate within-person variability and calculate the usual individual intake. The prevalence of food/food group intake reported by the adolescents was also estimated. For sodium, the prevalence of inadequate intake was estimated based on the Tolerable Upper Intake Level (UL). The Estimated Average Requirement (EAR) method used as cutoff was applied to estimate the prevalence of inadequate nutrient intake. All the analyses were stratified according to sex, age group and Brazilian macro-regions. All statistical analyses accounted for the sample weight and the complex sampling design. RESULTS Rice, beans and other legume, juice and fruit drinks, breads and meat were the most consumed foods among the adolescents. The average energy intake ranged from 2,036 kcal (girls aged from 12 to 13 years) to 2,582 kcal (boy aged from14 to 17 years). Saturated fat and free sugar intake were above the maximum limit recommended (< 10.0%). Vitamins A and E, and calcium were the micronutrients with the highest prevalence of inadequate intake (> 50.0%). Sodium intake was above the UL for more than 80.0% of the adolescents. CONCLUSIONS The diets of Brazilian adolescents were characterized by the intake of traditional Brazilian food, such as rice and beans, as well as by high intake of sugar through sweetened beverages and processed foods. This food pattern was associated with an excessive intake of sodium, saturated fatty acids and free sugar.

Dermatophyte susceptibilities to antifungal azole agents tested in vitro by broth macro and microdilution methods

The in vitro susceptibility of dermatophytes to the azole antifungals itraconazole, fluconazole and ketoconazole was evaluated by broth macro and microdilution methods, according to recommendations of the CLSI, with some adaptations. Twenty nail and skin clinical isolates, four of Trichophyton mentagrophytes and 16 of T. rubrum were selected for the tests. Itraconazole minimal inhibitory concentrations (MIC) varied from < 0.03 to 0.25 µg/mL in the macrodilution and from < 0.03 to 0.5 µg/mL in the microdilution methods; for fluconazole, MICs were in the ranges of 0.5 to 64 µg/mL and 0.125 to 16 µg/mL by the macro and microdilution methods, respectively, and from < 0.03 to 0.5 µg/mL by both methods for ketoconazole. Levels of agreement between the two methods (± one dilution) were 70% for itraconazole, 45% for fluconazole and 85% for ketoconazole. It is concluded that the strains selected were inhibited by relatively low concentrations of the antifungals tested and that the two methodologies are in good agreement especially for itraconazole and ketoconazole.

Scientific authorships and collaboration network analysis on Chagas disease: papers indexed in PubMed (1940-2009)

Chagas disease is a chronic, tropical, parasitic disease, endemic throughout Latin America. The large-scale migration of populations has increased the geographic distribution of the disease and cases have been observed in many other countries around the world. To strengthen the critical mass of knowledge generated in different countries, it is essential to promote cooperative and translational research initiatives. We analyzed authorship of scientific documents on Chagas disease indexed in the Medline database from 1940 to 2009. Bibliometrics was used to analyze the evolution of collaboration patterns. A Social Network Analysis was carried out to identify the main research groups in the area by applying clustering methods. We then analyzed 13,989 papers produced by 21,350 authors. Collaboration among authors dramatically increased over the study period, reaching an average of 6.2 authors per paper in the last five-year period. Applying a threshold of collaboration of five or more papers signed in co-authorship, we identified 148 consolidated research groups made up of 1,750 authors. The Chagas disease network identified constitutes a "small world," characterized by a high degree of clustering and a notably high number of Brazilian researchers.

VARIAÇÃO SAZONAL DOS MACRO E MICROELEMENTOS NO GÊNERO HUMIRIANTHERA (ICACINACEAE), EM FUNÇÃO DA IDADE

Foram analisados 26 espécimens de H. amplae 09 de H. rupestris,nas idades jovem e adulta, coletados nas estações seca e chuvosa, quanto ao teor total de N, F, K, Ca, Mg, Mo, Cu, Zn, Mn, Fe, B, Al, Co, Cr, Na, Pb, Si e Sr nas diferentes partes vegetativas das plantas. A concentração dos macro elementos nas folhas, caules e tubérculos de H. amplae H. rupeetrisobedece a relação N> Ca> Mg> F> K. A concentração média desses elementos indica que não há variabilidade significativa nos órgãos analisados e nem em relação às idades, com exceção do N que apresenta maior teor nas folhas e em relação aos outros elementos. Os microelementos apresentam uma distribuição uniforme nos diversos órgãos, sendo os de maior concentração Fe, Al e Na. Nesse estudo foi possível verificar o equílibrio mineral entre as espécies, pelos elementos e pelas relações K/Na, K/Mg, K/Ca + Mg + 100/Mn + 10/Cu. Análise dos resultados mostra que nas espécies pesquisadas não houve um equilibrio perfeito nas várias relações, com exceção de K/Ca + Mg. Analisou-se os solos onde as plantas se desenvolveram quanto aos teores totais dos macro e microelementos.

Quantificação de macro e micro nutrientes em algumas etnovariedades de cubiu (Solanum sessiliflorum Dunal)

Considerando a ampla variabilidade genética de cubiu (Solanum sessiliflorum Dunal), quantificaram-se os macro e micro-nutrientes, objetivando a ampliação da tabela de composição química de alimentos típicos da região amazônica. Os frutos provenientes da Estação Experimental de Hortaliças Alejo von der Pahlen (EEH) do Instituto Nacional de Pesquisas da Amazônia (INPA), localizados no km 14 da Rodovia AM 010 em Manaus, AM, foram processados no Laboratório de Alimentos e Nutrição do INPA. Avaliaram-se oito etnovariedades de cubiu identificados como: 2 I, 3 I, 6, 7, 12, 14, 17, 29 I e III em estádio de maturação comercial. Os teores de elementos minerais foram quantificados pela técnica de Ativação por Nêutrons Instrumental e a fibra alimentar pelo método enzímico-gravimétrico. Os resultados demonstram ser o cubiu um fruto com baixo conteúdo energético (média de 33 kcal), com conteúdo de fibra alimentar total na ordem de 1,6%. Em relação aos macros elementos minerais, a etnovariedade 6, apresentou a maior concentração em potássio (513,5±3,1mg), cálcio (18,9±0,6mg) e a etnovariedade 2 I em Fe (564,4±58,1µg) e Cr (99,3±8,3µg). A menor concentração foi constatada na etnovariedade 12 para os elementos K (229,0±4,5mg), Na (53,7±5,5µg) e Zn (89,3±4,7µg). Apesar das variações em relação as diferentes etno variedades e conseqüentemente concentrações em elementos minerais, o cubiu, pode estar contribuindo para atingir as recomendações desses nutrientes.

Macro-nutrientes no lençol freático em Floresta Intacta, Floresta de Manejo e Pastagem no norte de Mato Grosso

A remoção de uma cobertura florestal e sua substituição por outras formas de uso do solo tem sido uma constante no norte do estado de Mato Grosso podendo alterar os ciclos hidrológicos e biogeoquímicos dos ecossistemas. Neste contexto, o presente trabalho visou identificar a variação do fósforo e nitrogênio das águas do lençol freático em áreas de Floresta de Transição madura e intacta (Floresta Intacta), Floresta de Transição Manejada (Floresta Manejada) e Pastagem localizadas no norte de Mato Grosso. Foram realizadas mensalmente medidas do nível do lençol freático, de coletas de amostras de água para análises físico-químicas e medições de precipitação e temperatura do ar, no período de janeiro/2005 a novembro/2006. Verificou-se uma sazonalidade na precipitação e na temperatura do ar. No período de estiagem as águas do lençol freático apresentaram maiores teores de nitrogênio e de fósforo total nas três áreas em estudo. Os maiores valores de nitrogênio e fósforo foram detectados nos ecossistemas florestais (Florestas Intacta e Manejada) como indicativo da função da cobertura vegetal na ciclagem dos nutrientes.

Network Meta-analysis to Synthesize Evidence for Decision Making in Cardiovascular Research

Abstract Clinical decision-making requires synthesis of evidence from literature reviews focused on a specific theme. Evidence synthesis is performed with qualitative assessments and systematic reviews of randomized clinical trials, typically covering statistical pooling with pairwise meta-analyses. These methods include adjusted indirect comparison meta-analysis, network meta-analysis, and mixed-treatment comparison. These tools allow synthesis of evidence and comparison of effectiveness in cardiovascular research.

Variação na concentração e na quantidade de macro e micronutrientes no fruto do cafeeiro, durante o seu desenvolvimento

O presente trabalho apresenta os dados obtidos sôbre a variação na concentração e na quantidade de macro e micronutrientes no fruto do cafeeiro em função do seu grau de desenvolvimento, através da análise de amostras colhidas mensalmente. A variedade de café usada foi bourbon vermelho, de 9 anos de idade, localizada num solo latosólico roxo, no município de Charqueada. Os resultados obtidos mostraram que os frutos exigem contìnuamente todos os macronutrientes, desde o início de sua formação até a maturação. Com relação aos micronutrientes, o boro, cobre, ferro e molibdênio também foram solicitados contìnuamente, ao passo que o manganês e o zinco deixaram de ser absorvidos nos dois últimos meses de seu ciclo formativo. A exigência quantitativa de micronutrientes obedeceu a seguinte ordem decrescente: ferro, manganês, cobre, boro, zinco e molibdênio.

Nutrição mineral de hortaliças: XIX - absorção de macro e micronutrientes pela cultura do quiabeiro (Hibiscus esculentum L.)

O presente trabalho teve como objetivo estudar aspectos da nutrição mineral do quiabeiro (Hibiscus esculentus L.), no que concerne a: quantidades de macro e micronutrientes extraídos nas diversas fases do desenvolvimento, em duas variedades (Campinas 1 e Green Velvet). Sementes de ambas variedades foram postas a germinar em vasos contendo silica e irrigados com solução nutritiva completa. Plantas foram coletadas em períodos de 10 dias até aos 70 dias de idade, separadas em caule, folhas, flores e frutos. No material coletado foi determinado o peso da matéria seca e analizado quantitativamente para macro e micronutrientes, com excessão do cloro. Observou-se que o desenvolvimento em altura é idêntico em ambas as variedades; variedade Campinas 1 apresenta maior peso de matéria seca no final do ciclo; a extração dos nutrientes é lenta até aos 20 dias, acentuando-se após este período até o final do ciclo, em ambas as variedades; a extração de potássio pela var. Green Velvet é aproximadamente o dobro da var. Campinas 1; a var. Campinas 1 extrai maiores quantidades de micronutrientes.
