DIRETRIZES PROJETUAIS PARA ACESSIBILIDADE URBANA: UMA REVISÃO BIBLIOMÉTRICA
Full text linkIncreasing urbanization and the diversity of urban needs highlight the importance of effective design guidelines for accessibility in cities. This paper conducts a literature review to assess existing guidelines and their practical application. Despite regulatory advances, implementation faces challenges, including inadequate infrastructure and lack of maintenance of green areas. The review indicates that many urban environments still present significant barriers that affect mobility and quality of life, especially for children, the elderly, and people with disabilities. The study suggests that an integrated approach, with quantitative data and diverse perspectives, is essential to improve the effectiveness of guidelines and create inclusive urban environments. The findings highlight the need to overcome gaps in implementation to ensure equity and urban accessibility.La creciente urbanización y la diversidad de necesidades urbanas resaltan la importancia de directrices de diseño eficaces para la accesibilidad en las ciudades.

Energia Armazenada no Dossel Urbano, Ilha de Calor e Consumo Energético de Edifícios em Clima Tropical
Full text linkThe objective of this study is to evaluate the relationships between the energy stored in the canopy, the heat island (ICU) and the energy consumption of buildings located in urban and rural sites, in a tropical climate. Meteorological stations were used to collect data on energy balance, flow of heat stored in the soil, temperature and absolute humidity of the air, in the dry and rainy seasons. The heat flux in the soil was measured using a flow meter and the energy stored in the urban canopy was estimated. The Cooling Degree-Hour parameter was used to derive the energy consumption for cooling the bedrooms of a hypothetical building, located in urban and rural sites. The results indicated differences between the balance of available energy and stored energy in urban and rural sites, as well as between air temperature and humidity. The difference of 0.3MJ m-2day-1 of energy stored more in the urban environment in relation to the rural one, in the dry month, corroborated to raise the ICU intensity of 2.2°C, on average, in the urban canopy. In the rainy season, the difference was 0.8MJ m-2day-1 and an increase of 1.4°C was observed in the ICU. The bedrooms in the building located in the urban environment demanded 4.6kW/(m2month) more in September, to maintain the same thermal conditions as in February, which required 1.4kW/(m2month). The results demonstrate that buildings under the effect of the urban heat island phenomenon require greater energy demand to maintain similar conditions of habitability than in rural areas.El objetivo de este estudio es evaluar las relaciones entre la energía almacenada en el dosel, la isla de calor (ICU) y el consumo de energía de edificios ubicados en sitios urbanos y rurales, en un clima tropical. Se utilizaron estaciones meteorológicas para recolectar datos sobre balance energético, flujo de calor almacenado en el suelo, temperatura y humedad absoluta del aire, en las épocas seca y lluviosa. El flujo de calor en el suelo se midió con un medidor de flujo y se estimó la energía almacenada en el dosel urbano. El parámetro Grado-Hora de Enfriamiento se utilizó para derivar el consumo de energía para enfriar los dormitorios de un edificio hipotético, ubicado en sitios urbanos y rurales. Los resultados indicaron diferencias entre el balance de energía disponible y energía almacenada en sitios urbanos y rurales, así como entre temperatura y humedad del aire. La diferencia de 0,3MJ m-2día-1 de energía almacenada más en el ambiente urbano en relación al rural, en el mes seco, corroboró elevar la intensidad de la UCI de 2,2°C, en promedio, en el dosel urbano. En época de lluvias la diferencia fue de 0,8MJ m-2día-1 y se observó un aumento de 1,4°C en la UCI. Los dormitorios del edificio ubicado en el entorno urbano demandaron 4,6kW/(m2mes) más en septiembre, para mantener las mismas condiciones térmicas que en febrero, que requirió 1,4kW/(m2mes). Los resultados demuestran que los edificios bajo el efecto del fenómeno de la isla de calor urbana requieren una mayor demanda energética para mantener unas condiciones de habitabilidad similares a las de las zonas rurales.O objetivo deste estudo é avaliar as relações entre a energia armazenada no dossel, a ilha de calor (ICU) e o consumo energético de edificações localizadas em sítios urbano e rural, em clima tropical. Foram utilizadas estações meteorológicas para coletar dados de saldo de energia, fluxo de calor armazenado no solo, temperatura e umidade absoluta do ar, nas estações climáticas seca e chuvosa. O fluxo de calor no solo foi medido por meio de fluxímetro e a energia armazenada no dossel urbano foi estimada. Utilizou-se o parâmetro de Graus-Hora de Resfriamento para derivar o consumo de energia para refrigeração dos dormitórios de uma edificação hipotética, localizada nos sítios urbano e rural. Os resultados indicaram diferenças entre o saldo de energia disponível e a energia armazenada nos sítios urbano e rural, bem como entre a temperatura e umidade do ar. A diferença de 0,3MJ m-2dia-1 de energia estocada a mais no meio urbano em relação ao rural, no mês seco, corroborou para elevar a intensidade da ICU de 2,2°C, em média, no dossel urbano. No período chuvoso, a diferença foi de 0,8MJ m-2dia-1 e observou-se elevação de 1,4°C na ICU. Os dormitórios da edificação localizada no meio urbano demandaram 4,6kW/(m2mês) a mais no mês de setembro, para manter as mesmas condições térmicas do mês de fevereiro, que demandou 1,4kW/(m2mês). Os resultados demonstram que as edificações sob o efeito do fenômeno de ilha de calor urbana requerem maior demanda de energia para a manutenção de condições similares de habitabilidade que no meio rural
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
