Committed Moderates and Uncommitted Extremists: Ideological Leaning and Parties’ Narratives on Military Interventions in Italy
No full textCurrent research highlights that ideology decisively affects political contes-tation concerning peace and security operations in European countries. Inparticular, recent studies suggest that party preferences on this issue followa curvilinear distribution along the left-right axis, delineating a conflict be-tween moderate and extreme parties. However, the impact of this cleavageon the use of strategic narratives to either support or criticize these mis-sions requires more attention. This article aims to fill this gap by employ-ing seeded latent Dirichlet allocation, a semi-supervised automated textanalysis method, to analyze parliamentary debates on Italy’s most signifi-cant troop deployments between 1994 and 2013. We expect to find thatwhile moderates express a supportive narrative aimed at justifying the useof force, extremists attempt to delegitimize military interventions. Accord-ingly, we hypothesize that moderate parties emphasize more on the multi-lateral and humanitarian framework of a mission, while extremist partiesfocus more on its military means. The empirical findings largely confirmour hypotheses. By means of its method and results, the article contributesboth empirically and methodologically to the debate on the party politicsof military interventions in Europe
Power-Delay-Area-Noise Margin Trade-offs in Positive-Feedback Source-Coupled Logic Gates
No full textIn this paper, Positive Feedback Source-Coupled Logic (PFSCL) gates are analyzed from a design point of view. The design space is explored through analytical relationships which relate the gate delay, power consumption and noise margin, which are modeled through a simplified circuit analysis. To be more specific, a simple and accurate model of the noise margin is used to derive a systematic design strategy to size the transistors’ aspect ratios ensuring an assigned noise margin for a given bias current. From the knowledge of the transistor sizes, the gate delay is then expressed as a function of the bias current and the supply voltage, both of which define the static power consumption of PFSCL gates, as well as of the logic swing, which determines the noise margin. Therefore, this delay model simply relates the speed performance, the power consumption and the noise margin of PFSCL gates, and accounts for the dependence on the fan-in and the fan-out. Extensive SPICE simulations with a 0.18-m CMOS process confirm the adequate accuracy of the analytical models and the validity of the approximations introduced to simplify the analysis, and a practical design example of an equality comparator is also presented.
In order to derive clear guidelines to manage the delay-power-noise margin trade-off, PFSCL gates are analyzed in typical design cases (i.e. design for high speed, low power and power efficiency). For the sake of completeness, the effect of each design parameter on the silicon area occupied by a PFSCL gate is also qualitatively analyzed. The resulting criteria are thus useful to design PFSCL gates without resorting to time-consuming design iterations with a trial and error approach based on simulations
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
