Estudio sobre las variables que impactan los precios de vivienda nueva en Bogotá en sus diferentes segmentos económicos.
Get PDFLa inversión en vivienda en Colombia es uno de los principales motores de la economía del país en los últimos años y lo continuará siendo en los próximos. Esto debido al resultado de estudios donde el déficit habitacional del país es del 23.4% para el 2021. Sin embargo, este es un sector que ha tenido varios retos a lo largo de los últimos años en temas de financiación y acceso a gran parte de la población. Adicionalmente, requiere de altos montos de inversión y un estudio riguroso sobre el éxito del proyecto. En ese sentido, se realizó un estudio del comportamiento de los precios de la vivienda nueva de los últimos años. Para lo anterior, se utilizó una base de datos con más de 4900 proyectos con sus características básicas y su ubicación en la ciudad de Bogotá. De esta manera se hicieron análisis estadísticos en diferentes segmentos de precios para identificar las variables más importantes y si estas tenían cambios según el nivel de precio analizado. A diferencia de lo planteado, se pudo observar que las variables planteadas no tienen un impacto distinto en los diferentes precios y se confirmó la importancia de la ubicación en la determinación del precio de un inmueble. En ese sentido, los resultados nos permiten ver que, aunque las variables tengan comportamientos similares se debe hacer un estudio particular de la zona y no se puede hacer de modo general con todos los inmueblesResumen ; Marco teórico ; Revisión del estado de arte ; Metodología ; .

This is due to the result of studies where the country's housing deficit is 23.4% for 2021. However, this is a sector that has faced several challenges in recent years in terms of financing and accessibility for much of the population. Additionally, it requires large amounts of investment and a rigorous study of the success of the project. With this in mind, a study was conducted on the behavior of new housing prices in recent years. To do this, a database with over 4900 projects with their basic characteristics and location in the city of Bogotá was used. In this way, statistical analyses were performed in different price segments to identify the most important variables and if these had changes depending on the analyzed price level. Unlike what was proposed, it was observed that the proposed variables do not have a different impact on the different prices and the importance of location in determining the price of a property was confirmed. In this sense, the results allow us to see that, although the variables have similar behaviors, a particular study of the area must be done and it cannot be done in a general way with all properties.Maestrí

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
