KY electroproduction at CLAS12
No full textAn experimental program has been approved at the Thomas Jefferson National Accelerator Facility to measure the p(e, eK(+))Y reactions using the CLAS12 setup in Hall B. Data have been obtained using a 7.5 GeV electron beam, impinging upon a liquid-hydrogen target in the CLAS12 centre. The goal is to measure the Q(2) differential KY electroproduction cross section thus probing the Q(2) evolution of the N* resonance electrocouplings in the Q(2) range from 0.05GeV(2) to 3GeV(2): this will provide a crucial tool to investigate the possible hybrid nature of the N* resonances. Preliminary results from CLAS12 data are reported

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
Application of geographical information systems in the analysis of hydrological inputs to a shallow Mediterranean coastal aquifer
No full textContributions to the groundwater flow within the catchment domain are due to natural subsystems such as direct infiltration, recharge from surface networks and subsurface water flowing through the slopes. Groundwater quality is affected by such contributions in the case of surface water contamination; the space and time scales of the subsystems connections are investigated in the paper. As a distributed recharge evaluation is needed along the aquifer boundaries for providing inputs to traditional models, a distributed approach to the simulation of subsystems is proposed: GIS capabilities support the management of the large amount of information describing the catchment hydrology. Application of a hydrologically oriented GIS to the problem of recharge evaluation in the case of the Bisagno aquifer (Italy) is presented: procedures have been developed in order to link together different hydrological processes resulting into a subsurface flow model able to simulate the catchment contribution to the groundwater flow in the aquifer. -Author
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
