No full textTreballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2015, Director: Jordi Vitrià i MarcaThis project came up after a few meetings with the professor Dr. Jordi Vitrià talking about Data Science, the possibilities inside this sector, about interesting projects that people made using Data Science, we talked about some cases that could be interesting to analyse, all with a spot in mind, the possibility of reaching a result and visualize that result in an understandable way. So, after those inspiring meetings we achieved the main idea of this project: Geolocation of news.
Regarding the journalism sector, hundreds of news are published every day, but unfortunately not all of them include a proper geographic reference. All those news with a reference to a geographic location let the door open to a new way of distribution, and also let new ways of analysis based on this new parameter, the location.
As an example, imagine that a developer wants to let a user with a smartphone or a tablet, receive automatically the news related to the place where the user is.
Without a reference to where the news took place it is difficult to face the problem, however with a reference to a place the problem now seems affordable.
During the realization of this project, various tools and methods are used in order to obtain automatically a set of georeferenced tags from the news and thus be able to show the results in an easy way to analyse.
Despite being this project based in the concept of Data Science, I am not explicitly using algorithms from the world of Data Science (in this report I will explain the reasons why some algorithms could not be used), I follow, however, the main principles: look for databases that can help me face the problem, clean all data in order to be able to use it, and finally I try to show the results in an understandable way to reach results or conclusions.
This document outlined in detail the design, development and implementation of every single step that was necessary to achieve the final result.
In order to see the results in a simple way, I also created a website with a summary of all the project and some visualizations of the results under the following URL: http://alsolanes.github.io/TF

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
Can we increase the subjective well-being of the general population? An umbrella review of the evidence
No full textSubjective well-being (SWB) refers to being satisfied with one's life, having positive affect and having little negative affect. We may understand it as a subjective definition of good life, or in colloquial terms "happiness", and it has been associated with several important benefits such as lower mortality. In the last decades, several randomized controlled trials (RCT) have investigated the efficacy of several interventions in increasing SWB in the general population but results from different disciplines have not been integrated
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
Advances in Using MRI to Estimate the Risk of Future Outcomes in Mental Health - Are We Getting There?
Full text linkSchizophrenia is a mental disorder among the leading disabling conditions worldwide. It affects approximately 20 million people and increases 2–3 times the probability of dying early and decreases the life expectancy by about 20 years. Its onset is typically in adolescence or early adulthood. Relevantly, prolonged untreated psychosis leads to poorer outcomes, so detecting the disorder early could considerably improve their lives
