La scrittura in italiano LS in apprendenti sinofoni: tra testualità e retorica
No full textWriting skills are a founding pillar of the linguistic-communicative competence of the L2 speakers, which requires a long process of learning and teaching. Based on a corpus analysis of texts written by 24 Chinese learners of Italian, this paper aims to explore whether elements attributable to construction models of the text typical of L1 affect the writing of second language and its embodiment. We analyze this corpus according to both the Contrastive (or Intercultural) Rhetoric and Second Language Acquisition point of views. The conclusion offers the result of the analysis with some reflections on teaching writing in Italian for Chinese students
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
Spatial Views Language Specification, Version 1.0
No full textThe goal of SpatialViews (SV) is to provide a high-level programming model that allows application programmers to easily develop and maintain their mobile ad-hoc network applications. Each node in the network is assumed to have substantial computation and communication capabilities, and is aware of its spatial location. The location of a node can be queried by the user level program, i.e., a particular location may determine the actions performed by a program. Resource-constrained sensor networks are not the main target of SpatialViews . Examples for target network nodes are state-of-the-art smart phones, PDAs, notebook, and laptop computers.
The language is a vehicle to study different language, compiler optimizations, and performance trade offs. Clearly, not all conceivable applications may be implemented within the framework of this programming model. Our goal is to provide a high-level programming model for a large class of mobile applications for ad-hoc networks that hides many details of the underlying volatile target networks. In this sense, SpatialViews is complementary to lower level languages such as nesC [4], SP [2] and SM [7]. A programming language approach was choosen for SpatialViews instead of a library (API) approach in order to allow more aggressive optimizations and more efficient program analyses.
The SpatialViews language is an extension of a Java subset. The main program abstraction in SpatialViews is that of a space-time region of virtual network nodes that provide specific services. A SpatialViews can be thought of as a type specification that describes the desired network type and properties. This space-time region or type is called a spatial view.Thespatial view definition is declarative in nature, i.e., does not instantiate any mapping between virtual and physical nodes. This is done through as briefly discussed in the next paragraph.
An iterator allows the programmer to specify actions on nodes in the spatial view. The operational semantics of the iterator is based on migration, i.e., the programmer can imagine that each iteration is performed on a different virtual node, with program migration performed implicitly between the iterations. The spatial view is instantiated by discovering and migrating to network nodes that match the type definition of the spatial view. Constraints on the discovery and migration process may be specified as part of the iterator. A time limit is a required constraint for each iterator. Each virtual node in a spatial view can be instantiated, i.e., visited at most once.
Due to the volatile and mobile nature of the underlying target network, SpatialViews does not support any explicit mapping between a virtual network node and its corresponding physical node. In other words, the language does not provide names (e.) of a physical node across iterations. Any physical node that matches the virtual node type as specified in a spatial view can be an instance of that virtual node. The motivation for this restriction is the fact that any particular binding of virtual and physical nodes cannot be guaranteed to be valid during the program execution due to the volatility of the underlying network.
The programming model introduced by SpatialViews could be implemented as an extension to the Java programming language through additional syntax and semantics, or through a Java package that contains class definitions that may be imported Java programs. There are advantages and disadvantages to both approaches. We chose the programming language approach which allows a better control of the semantics of the newly introduced programming model concepts.Technical report DCS-TR-56
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
