Vortex dynamics and irreversibility line in optimally doped SmFeAsO0.8F0.2 from ac susceptibility and magnetization measurements
No full textAc susceptibility and static magnetization measurements were performed in the optimally doped SmFeAsO0.8F0.2 superconductor. The field-temperature phase diagram of the superconducting state was drawn, and, in particular, the features of the flux lines were derived. The dependence of the intragrain depinning energy on the magnetic field intensity was derived in the thermally activated flux-creep framework, enlightening a typical 1/H dependence in the high-field regime. The intragrain critical current density was extrapolated in the zero-temperature and zero-magnetic-field limit, showing a remarkably high value Jc0(0)~2×10^7 A/cm2, which demonstrates that this material is rather interesting for potential future technological applications
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
Consonanza e governo dell’impresa tra oggettivismo e soggettivismo
No full textNel lavoro si propone uno studio sul governo dell’impresa e si individuano ed esaminano le principali fasi evolutive delle teorie e degli strumenti a supporto delle decisioni aziendali.
Di particolare momento, in quest’ambito, è il ruolo svolto dalla conoscenza, dal momento che nella concezione sistemico vitale dell’impresa, la consonanza può essere considerata quale strumento di governo dell’impresa proprio attraverso l’apprendimento cognitivo reciproco che qualifica i sistemi interagenti consonanti.
Il lavoro, infine, sottolinea l’importanza di guardare all’impresa in un’ottica quali-quantitativa e interattiva piuttosto che strutturalista e quantitativa, al fine di fornire all’organo di governo dell’impresa indicatori adeguati a supporto del processo decisionale. Tale esigenza emerge dall’inadeguatezza delle più diffuse teorie e tecniche, che si sono rivelate non idonee a supportare adeguatamente i decisori nell’ambito delle scelte d’impresa. A prova di ciò, vengono qui riportati alcuni casi di valutazione della consonanza che riguardano i possibili rapporti tra impresa e ambiente e vengono proposti alcuni indici di valutazione per stimare il grado di consonanza.In the work is proposed a study on corporate governance and identify and examine the main evolutionary stages of the theories and tools to support business decisions. Of particular time, in this context, is the role played by knowledge, since systemic vital in the design of the company, the consonance can be considered as an instrument of governance through their mutual cognitive learning that qualification systems interacting consonanti.Il work, finally, emphasizes the importance of looking to the company with a view quantitative and interactive rather than structuralist and quantitative, in order to provide the organ of governance indicators adequate to support the process decision-making. This need emerges from the inadequacy of the most popular theories and techniques that have proven to be unfit to adequately support decision-makers in the context of business decisions. As proof of this, here are a few reports of evaluation of consonance concerning possible relationships between business and the environment are proposed and some evaluation indices to estimate the degree of consonance
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
