Applications of the Gaussian kinematic formula to CMB data analysis
No full textThe Gaussian Kinematic Formula (GKF, see Adler and Taylor (2007,2011)) is an extremely powerful tool allowing for explicit analytic predictions of expected values of Minkowski functionals under realistic experimental conditions for cosmological data collections. In this paper, we implement Minkowski functionals on multipoles and needlet components of CMB fields, thus allowing a better control of cosmic variance and extraction of information on both harmonic and real domains; we then exploit the GKF to provide their expected values on spherical maps, in the presence of arbitrary sky masks, and under nonGaussian circumstances. All our results are validated by numerical experiments, which show a perfect agreement between theoretical predictions and Monte Carlo 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
Monitoring and Modelling Hydrological Processes in Greenhouse Horticulture Districts
No full textThe hydrological response of greenhouse horticulture districts has not been comprehensively investigated, neither from a monitoring nor a modelling point of view. Some land reclamation authorities are now challenged by an increasing flood risk, due to plastic covers expanding imperviousness. In the south of Italy, we are monitoring a 10.1 km2 agricultural catchment, covered by plastic greenhouses, where we apply the integrated surface-subsurface hydrological model “CATchment HYdrology” (CATHY) to obtain a mechanistic understanding of surface water and groundwater processes. We are also developing a greenhouse environmental model, based on previously published research, to estimate indoor crop transpiration given outdoor meteorological variables. The greenhouse climate model was validated on experimental data and it was able to simulate indoor air temperature and relative humidity with satisfying accuracy. Upon using the Penman-Monteith equation for calculating the reference evapotranspiration (ET0) indoor and outdoor, we determined that ET0 was lower indoor than outdoor by about 1 mm/day on average over 35 days. The CATHY model simulated the water levels at the outlet in accordance with measured values. Numerical scenario analyses corroborated an increase in streamflow during rain events and revealed a substantial reduction in groundwater recharge
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
