No full textThe susceptibility measures the probability of occurrence of a phenomenon under study. It estimates how much the predisposing factors affect past phenomena in order to predict future scenarios.
Numerous tools and software are available for susceptibility analysis. Some of them are focused on spatial susceptibility or susceptibility zoning and are developed on both proprietary and open-source Geographical Information Systems, such as: GRASS r.landslide (Bragagnolo et al., 2020), ArcGIS ArcSDM (Kemp et al. 2002) and Toolboxes (Jebur et al., 2015), R LAND-SE (Rossi & Reichenbach, 2016), R RSAGA (Brenning et al., 2018).
In this work, a new open-source tool for susceptibility zoning has been implemented for the QGIS software, named Susceptibility Zoning plugin (SZ-plugin). It allows to map the susceptibility of a specific object of study in the selected area. In particular, the plugin has been developed for landslide susceptibility mapping in the context of the project Silk Road Disaster Risk Reduction of the Belt and Road Initiative (Lei et al., 2018) to prevent and mitigate the risk induced by landslides on the infrastructure.
The code has been written in Python3 using third-party libraries and plugins such us: scikit-learn (Pedregosa et al., 2011), NumPy, Matplotlib (Caswell et al., 2020 ; Hunter, 2007), GDAL, Qt and QGIS Plugin Builder.
The plugin version 0.1 maps the susceptibility through two statistical methods: Weight of Evidence and Frequency Ratio. The analysis provides a measure of the probability of occurrence expressed by the Susceptibility Index (SI). Moreover, the SZ-plugin allows to evaluate the prediction and success capacity of the model by the representation of the Receiver Operating Characteristic (ROC) curves based on the training and validating datasets respectively.
The result is an efficient tool which supports the susceptibility zoning from the spatial analysis to the validation of the method and results.

„Egy olyan hatalmas gazdaságot, mint amilyen Oroszországé, aligha lehet szankciókkal megroppantani.” – Interjú Sz. Bíró Zoltán Oroszország szakértővel az orosz gazdaság fejlődési lehetőségeiről
Full text linkA Világpolitikai és közgazdaságtan interjút készített Sz. Bíró Zoltánnal Oroszország közép és hosszú távú gazdasági fejlődési lehetőségeiről. Az interjú apropóját az adta, hogy ebben az évben jelent meg Sz. Bíró Zoltán Putyin háborúja című kötete (https://gondolatkiado.hu/webshop/PROGRESS-konyvek/putyin-haboruja/) a Gondolat Kiadó gondozásában, amiben a háború okait és előzményeit mutatta be. Az interjúban Oroszország gazdasági jövőjéről kérdeztük
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

Szász–Durrmeyer Operators Involving Confluent Appell Polynomials
No full textThis article is concerned with the Durrmeyer-type generalization of Szász operators, including confluent Appell polynomials and their approximation properties. Also, the rate of convergence of the confluent Durrmeyer operators is found by using the modulus of continuity and Peetre’s K-functional. Then, we show that, under special choices of A(t), the newly constructed operators reduce confluent Hermite polynomials and confluent Bernoulli polynomials, respectively. Finally, we present a comparison of newly constructed operators with the Durrmeyer-type Szász operators graphically
