Temporal evolution of water risk in Santa Fe towns with different levels of urban development in the context of climate change
No full textFil: Gardiol, Mario Rubén. Universidad Nacional del Litoral. Facultad de Ingeniería y Ciencias Hídricas; Argentina.Los modelos climáticos globales que realizan pronósticos con diferentes horizontes temporales (al 2040 y al 2100), indican que para Argentina, la temperatura aumentará hasta 1°C, en promedio (Camilloni, 2018). En relación con las precipitaciones extremas, en el período 1960-2010, se verificó un aumento de las intensidades y frecuencias. Según estos modelos indican que las precipitaciones podrían aumentar hasta un 10% su cuantía (Ministerio de Ambiente y Desarrollo Sustentable, 2015). Además, se suma las complejidades propias del desarrollo y expansión de las localidades, potenciando los efectos del CC y los impactos, principalmente en términos de riesgo hídrico. Esta situación genera, en un futuro cercano, que se considere necesariamente, estos procesos climáticos para la gestión del territorio, por tanto, es necesario disponer de información técnica relevante. En este proyecto el equipo de investigación propone analizar las amenazas, vulnerabilidades y riesgo ante fenómenos de origen hídrico en localidades que presentan diferentes grados de desarrollo urbano-territorial. El estudio incluirá diferentes periodos de tiempo en los que se integrarán las estrategias de gestión y acciones colectivas que se llevaron a cabo para mitigar el riesgo hídrico. Se triangulará entre metodologías cuantitativas y cualitativas, para llevar a cabo el proyecto. Las primeras operarán a partir de información de carácter secundaria y las segundas, a partir de entrevistas a referentes y actores claves del territorio. Los principales resultados esperados son: contar con cartografías de riesgo hídrico para cada una de las localidades estudiadas en los distintos periodos de tiempo y comprender la interrelación entre los niveles de riesgo identificados con las estrategias de gestión y las acciones colectivas. La cartografía obtenida podrá ser utilizada como herramienta para la toma de decisiones, en políticas para la reducción y/o mitigación del riesgo hídrico.Global climate models that make forecasts with different time horizons (2040 and 2100), indicate that for Argentina, the temperature will rise to 1 ° C, on average (Camilloni, 2018). In relation to extreme rainfall, in the period 1960-2010, an increase in intensities and frequencies was verified. According to these models, they indicate that rainfall could increase its amount up to 10% (Ministry of Environment and Sustainable Development, 2015). In addition, it adds the complexities of the development and expansion of localities, enhancing the effects of climate change and impacts, mainly in terms of water risk. This situation generates, in the near future, that these climatic processes are necessarily considered for the management of the territory, therefore, it is necessary to have relevant technical information. In this project, the research team proposes to analyze the threats, vulnerabilities and risks to phenomena of water origin in localities that present different degrees of urban-territorial development. The study will include different periods of time in which the management strategies and collective actions that were carried out to mitigate water risk will be integrated. It will be triangulated between quantitative and qualitative methodologies, to carry out the project. The former will operate based on secondary information and the latter, based on interviews with referents and key actors in the territory. The main expected results are: to have water risk maps for each of the locations studied in the different periods of time and to understand the interrelation between the levels of risk identified with management strategies and collective actions. The cartography obtained can be used as a tool for decision making, in policies for the reduction and/or mitigation of water risk
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
