L’ufficio di Sant’Omobono : contributo alla ricostruzione dei testi e delle musiche
No full textNell'ultimo decennio il mondo accademico si è occupato con interesse crescente di Omobono, santo poco noto fuori dalla diocesi di Cremona, sebbene nei secoli XV e XVI il suo culto si sia esteso a Nord e oltre i confini della penisola.l Non a torto I'eminente medievista André Vauchez lamentava nel 1981 e ancora nel 1987 una penuria di documenti e di dati sul santo,2 parzialmente colmata nel 1991 da Daniele Piazzi, ma soprattuto nel 2001 da una breve monografia dello stesso Vauchez, destinata ad acquisire autorevolezzatra gli studi sulle vicende terrene, la santità e il culto del pio cremonese.3 Le ultime ricerche hanno restituito una dignità storica a Omobon o che ora figura in testa all'elenco dei santi e in particolare di quelli laici per cui ebbe inizio un processo di canon rzzazion
Investigation of the tribological properties of different textured lead bronze coatings under severe load conditions
No full textThe purpose of this paper is to investigate the variation in the coefficient of friction (CoF) and also the wear in a lead bronze coating under different texture conditions. The tribological tests were performed using a tribometer with pin on disk configuration. Several kinds of textures, realised by a surface laser texturing, were tested by varying the diameter, depth, and density of the dimples under severe working conditions. The innovative aspect concerns the behaviour of the textured lead bronze coating and the lubrication conditions when the sample is subjected to extreme load conditions. Confocal microscopies and SEM (Scanning Electron Microscopy) / EDS (Energy Dispersive X‐Ray Spectroscopy) analyses were performed to evaluate the texture behaviour and also the surface deterioration of the coating. The results show that the application of texture processing leads to an improvement in the tribological properties of the coating. By analysing separately the variation of the different geometric parameters of the dimples, it has been shown that the best results are obtained with a diameter of 50 μm, a density of 5%, and a depth of 5 μm
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
Analysis of the Structural Behavior of Racing Motorcycle Swingarms
No full textThe problems which arise during the design of a motorcycle,
may affect the proper functioning of the vehicle, and ride
comfort. This type of problem is particularly found in sport
where mechanical components which can cause
malfunctioning should, be replaced quickly within a very
limited time.
This work is an investigation of the swingarm component.
The aim is to link objective data such as stiffness and natural
frequencies (derived through the application of scientific
method) with subjective information such as handling and
comfort perceived by professional riders. The testers were
two riders of the 2008 World SuperBike Championship. They
were chosen to represent two kinds of driving behaviors: one
of them had a affable riding attitude, whereas, the second was
more aggressive.
Three motorcycle swingarms used in the 2008 World
SuperBike Championship, were mechanically characterized:
FEM and experimental investigations were performed. The
characterization of the swingarm concerns, in particular
torsional stiffness. The swingarm is a component with a semisymmetrical
geometry, but it has a very antisymmetric. In
fact, there are two distinct values of torsional stiffness, one
clockwise and the other counterclockwise. In addition, the
torque does not occur along the axis of symmetry of the
swingarm, but it may deviate from the axis very clearly. The
three swingarms analyzed have different antisymmetric
behavior; these differences affect to the choice of which rider
for good handling
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
