Communication strategies in distributed agent-based simulations: The experience with D-Mason
No full textAgent-Based simulation Models (ABMs) are a very powerful experimental tool of analysis, used in many scientific and technological communities of researchers, to assess and predict the dynamic unfolding of a series of events or processes, according to the imposition of certain conditions, given by the analyst. The computing power usually represents a limit for such simulations and the traditional answer to the need for computing power is to invest in computer resources. D-Mason is a framework for parallelizing simulations developed on top of Mason toolkit. The goal of D-Mason is to exploit wasted computing power in a network of computers, eventually heterogeneous, as a research lab or a cluster of workstation. In this paper we present a novel communication strategy using Publish/ Subscribe paradigm through a layer based on the MPI Standard. © 2014 Springer-Verlag Berlin Heidelberg
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
Distorsioni informative nel decision-making process del consumatore
Full text link2013 - 2014L’obiettivo principale di questo lavoro è quello di contribuire al dibattito
internazionale esistente in materia di tutela del consumatore, una disciplina di
particolare rilevanza per la vita quotidiana di tutti i cittadini.
Lo studio trova il proprio incipit, nel capitolo 1, in una presentazione
“interdisciplinare” del profilo del consumatore. In particolare, dopo una
ricostruzione storica della tutela del consumatore e del consumerismo vengono
proposti diversi approcci sociologici, psicologici ed economici del consumer decision
process.
Nel capitolo 2 vengono presentate una serie di indagini conoscitive e ricognizioni
sullo stato dell’arte volte a ricostruire i più recenti interventi normativi che hanno
interessato la materia, fino ad arrivare alla nuova tutela dei consumatori recepita
nell’ultimo decreto legislativo 21/2014 che adotta un approccio di “full
harmonization” finora inedito.
L’attenzione si sposta poi, nel capitolo 3, sul ruolo dell’informazione fornita ai
consumatori in materia di pratiche commerciali scorrette, nell’ambito della
disciplina del Codice del consumo. Il “diritto all’informazione” del consumatore
costituisce, infatti, la linea direttrice che accompagna tutto lo svolgimento del
rapporto di consumo. Nello specifico lo studio si sofferma sul confine estremamente
labile tra effetto informativo ed effetto decettivo e sulle diverse tipologie di
distorsioni informative che caratterizzano il rapporto consumatore-professionista.
L’ultima fase della ricerca è dedicata, nel capitolo 4, all’analisi di alcuni leading cases
rappresentativi delle diverse fattispecie distorsive proposte. [a cura dell'Autore]The main objective of this work is to make a contribution to the existing international debate with regard to the consumer protection, a very important discipline for all citizens’ daily life.
The opening words of this study may be found in chapter 1, in which an interdisciplinary consumer’s profile is defined. In particular, after a historical reconstruction of consumer protection and consumerism, different economical, psychological and sociological approaches of consumer decision process are proposed.
In chapter 2 a series of surveys and recognitions are introduced in regard to the state of the art in order to rebuild the latest set of rules which are related to this matter (discipline) until is coming of the new consumer protection of the latest legislative decree 21/2014 that adopts an approach of "full harmonization" unpublished up to now.
In chapter 3 the focus of attention is on the information role for the consumers as concerns the unfair trade practices within the Consume Code (Discipline).
The consumer’s right to information is, infact, the guideline of the whole development of consumption relationship. [edited by Author]XIII n.s
