Diferenciación socio espacial y calidad de vida urbana: El caso de la ciudad de Bahía Blanca
No full textAl abordar el estudio de la calidad de vida de la población se destacan las condiciones del hábitat por su relación directa con la salud y las de índole material del ámbito en que vive. Las condiciones de pobreza se han intensificado en los últimos años, como se evidencia en la precarización del hábitat, para aquellos sectores de la población de menores recursos...Fil: Prieto, Maria Belen.

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
Calculation of the carbon footprint in the production of low-density polyethylene (LDPE) resins in a post-consumer material recycling plant in Tocancipá, Colombia
No full textEl plástico ha sido un impulsor clave de la demanda de materias primas petroquímicas de la industria
del petróleo y el gas, con un ciclo de vida breve que culmina en vertederos, incineración o desechos.
En 2019, la cadena de valor del plástico, desde la producción hasta la disposición, contribuyó con
más de 850 millones de toneladas métricas de gases de efecto invernadero. Para abordar este desafío
y fomentar la gestión sostenible, se promueve el reciclaje mecánico para producir resinas a partir de
plástico posconsumo. Sin embargo, se necesitan más estudios para determinar su impacto ambiental
y mejorar estrategias, especialmente en relación con el potencial de calentamiento global (GWP).
Este proyecto se centró en calcular la huella de carbono utilizando SimaPro para la fabricación de
resina reciclada de polietileno de baja densidad (PEBD) a partir de plástico posconsumo doméstico
en la planta de posconsumo de Reciclene. Adoptando un enfoque de ciclo de vida desde la obtención
del material en la Estación de Clasificación (ECA) hasta la entrega al fabricante, pasando por la
manufactura en la planta de aprovechamiento. Los resultados mostraron una huella de 3.36 kg de CO2
eq. por kilogramo de pellets de PEBD, siendo la energía el factor más contribuyente con un 82.6%.
Como estrategia, se propone la implementación de un sistema de gestión energética según la norma
ISO 50001:2018 para mejorar la eficiencia y reducir la huella de carbono. Estos hallazgos subrayan
la necesidad de enfoques integrales y sostenibles para abordar los desafíos ambientales asociados con
la producción y disposición de plásticos.Universidad El BosqueIngeniero AmbientalPregradoPlastic has been a key driver of demand for petrochemical raw materials from the oil and gas industry,
with a short lifecycle culminating in landfills, incineration, or waste. In 2019, the plastic value chain,
from production to disposal, contributed to over 850 million metric tons of greenhouse gas emissions.
To address this challenge and promote sustainable management, mechanical recycling is encouraged
to produce resins from post-consumer plastic. However, further studies are needed to determine its
environmental impact and enhance strategies, particularly regarding the potential for global warming
(GWP). This project focused on calculating the carbon footprint using SimaPro for the manufacturing
of recycled low-density polyethylene (LDPE) resin from post-consumer domestic plastic. Adopting
a lifecycle approach from material acquisition at the Sorting Station (ECA) to delivery to the
manufacturer, including processing at the recovery plant. The results revealed a footprint of 3.36 CO2
2 eq., with energy being the most contributing factor with 82.6%. As a strategy, the implementation of
an energy management system according to ISO 50001:2018 is proposed to improve efficiency and
reduce the carbon footprint. These findings underscore the need for comprehensive and sustainable
approaches to address the environmental challenges associated with the production and disposal of
plastics
