The first steps of the Clinical Neurology in South America
No full textThe field of neurology in South America began to emerge toward the end of the 19th century, following the origin of the specialty in Europe. There was a consistent and long-standing admiration for European training, which led to the birth of the discipline in South America. The first steps took place almost simultaneously with European countries in Argentina, Brazil, Uruguay, Chile, and Peru. In the other countries, the development of neurology took place later in the 20th century.Fil: Allegri, Ricardo Francisco. Fundación Para la Lucha Contra las Enfermedades Neurológicas de la Infancia.

Managing uncertainty in the start-up environment. Is a business plan an incentive or a limitation?
No full textThe purpose of this paper, which participates in the lively debate between the Learning School and the Planning School, is to investigate whether a business plan can still support planning a start-up in uncertainty conditions. By analyzing the strengths, weaknesses, opportunities, and threats of the business plan process, we propose an evolution of such a process, through the use of simulation models, to manage uncertainty. Using simulation models, especially what-if simulations, the start-up founder is able to improve the cognitive process in order to assess the project’s feasibility. Furthermore, with simulation, business plan overcomes some of its traditional weaknesses and improves its strengths and opportunities. It can also become a training tool in the entrepreneurship programs promoted by public institutions. By integrating forecasting, planning and simulation models, the business plan can be more comprehensive and provides more information about the environment in which the start-up has to play the game. Thus, the business plan becomes “not just an evaluation of a project’s profitability, but also the future story of an idea, in which people are the central point of the success”
Automated prediction of the QoS of service orchestrations: PASO at work
No full textPredicting the QoS of a service orchestration is not easy because of the a priori undetermined behaviour of invoked services, and because of the non-determinism (alternatives, unbounded iterations, fault handling) and complex structure (dependencies, correlations) of the workflow defining a service orchestration. In this paper we illustrate the practical usefulness of a probabilistic analyser of service orchestrations (PASO) by showing how it can be fruitfully exploited to predict the QoS of service orchestrations

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
Probabilistic prediction of the QoS of service orchestrations: A truly compositional approach
No full textThe ability to a priori predict the QoS of a service orchestration is of pivotal importance for both the design of service compositions and the definition of their SLAs. QoS prediction is challenging because the results of service invocations is not known a priori. In this paper we present an algorithm to probabilistically predict the QoS of a WS-BPEL service orchestration. Our algorithm employs Monte Carlo simulations and it improves previous approaches by coping with complex dependency structures, unbound loops, fault handling, and unresponded service invocations
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
