From alternative representations to prospective visions. The administrative subdivisions in Palermo (Italy)
No full textAlternative representations of the city are not only a useful analysis tool, but they also provide elements of a conceived new version of lived space that can contribute to ameliorate the spatial justice of the city. This is even truer for intra-local spaces that are the reference scale for many public participation policies, grass-root projects and activists.
In this paper, we present the case of Palermo where the administrative subdivisions of the urban space have been imposed – because of legislation about administrative decentralisation – on the historical and perceived ones.
Alternative mapping shows intra-local spaces as places of identity definition and civic engagement. In our paper we present some examples of how local stakeholders represent their prospective visions for the neighbourhoods they live or act in
Técnicas de modelado matemático. Desarrollo y aplicaciones
Full text linkTesis (Doctor en Matemática)--Universidad Nacional de Córdoba, Facultad de Matemática, Astronomía, Física y Computación, 2022.Fil: Buffa, Bruno Adolfo. Universidad Nacional de Córdoba. Facultad de Matemática, Astronomía, Física y Computación; Argentina.Los modelos matemáticos se utilizan para el estudio, análisis y comprensión
de diferentes fenómenos abordados por las ciencias exactas y de la salud, como
ası́ también en ciencias sociales. Un modelo puede ser definido como la representación de algún sistema real o abstracto que tiene por fin último resolver un
problema o responder cierta pregunta relacionada a ese sistema. En términos generales, el objetivo del proceso de modelado es entender el funcionamiento, explicar
patrones observados y predecir el comportamiento frente a eventuales cambios
en el sistema estudiado. Tradicionalmente, el enfoque estándar para el modelado matemático se apoyó en modelos basados en ecuaciones diferenciales, pero
sin embargo en la literatura de los últimos años se destaca la implementación de
nuevas perspectivas. Este trabajo se orienta al estudio de distintos tipos de modelización a través de herramientas matemáticas que se apartan de los cánones
usuales de modelado, para lo cual se presentan tres enfoques de modelización no
convencionales.Mathematical models are used for the study, analysis and understanding of different phenomena in the exact and health sciences, as well as in the social sciences. A model can be defined as the representation of some real or abstract system whose ultimate purpose is to solve a problem or answer a certain question related to that system. In general terms, the objective of the modeling process is to understand the functioning, explain observed patterns and predict behavior in the face of eventual changes in the system under study. Traditionally, the standard approach to mathematical modeling has relied on models based on differential equations, but in the literature of recent years, the implementation of new perspectives has been highlighted. This work is oriented to the study of different types of modeling through mathematical tools that depart from the usual modeling canons, for which three non-conventional modelling approaches are presented.Fil: Buffa, Bruno Adolfo.

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
Parameter estimation and measurement of social inequality in a kinetic model forwealth distribution
Full text linkThis paper deals with the modeling of wealth distribution considering a society with non-constant population and non-conservative wealth trades. The modeling approach is based on the kinetic theory of active particles, where individuals are distinguished by a scalar variable (the activity) which expresses their social state. A qualitative analysis of the model focusing on asymptotic behaviors and measurement of inequality through the Gini coefficient is presented. Finally, some specific case-studies are proposed in order to carry out numerical experiments to validate our model, characterize societies and investigate emerging behaviors.Fil: Buffa, Bruno Adolfo.
