Assessing climate impacts on slow-moving landslides in the western Alps of Piemonte: integration of monitoring techniques for detecting displacements
Full text linkThe influence of climatic factors on landslides triggers and displacement rates is a crucial research topic, especially due to the growing need to understand the evolution of climate change in historical periods of intense precipitation and anomalous temperature increases. Italy, highly prone to hydrogeological instability, extremely its mountainous regions such as the Alps, stands as a pertinent subject area for instability scenarios. However, the interpretation of climate effects on landslides is still an open issue. This work proposed a simplified methodology for investigating the displacements of three slow-moving landslides located in the Western Alps of Piemonte region, in response to significant meteorological events evaluated from reference normal of precipitation and temperature trends over the reference period 1991–2020. Another purpose is to emphasize the advantages of using different monitoring techniques by comparing displacement time series measured with in situ and remote sensing instruments, to detect ground deformation processes of these gravitational phenomena. The existence of a robust monitoring network, coupled with InSAR dataset support, has allowed detecting climatic factors’ impact on displacement rates for the outlined case studies. The results have demonstrated the relationships between the identified climatic events and variations in displacement time series, as well as the potential of integrating field observations and InSAR techniques to improve the interpretation of landslide dynamics. Although this study has laid the basis for understanding the influence of climatic factors on landslide displacements, there is still much to investigate and refine. The proposed preliminary analysis will further improve the ability to predict, monitor and mitigate landslide risk under changing climate conditions
COMPREHENDING MOUNTAIN SPRINGS’ HYDROGEOLOGICAL PERSPECTIVES UNDER CLIMATE CHANGE IN AOSTA VALLEY (NORTHWESTERN ITALY): NEW AUTOMATED TOOLS AND SIMPLIFIED APPROACHES
Full text linkMountain springs' recharging mechanisms have undergone significant changes due to climate change, as well as altered water consumption patterns and policies. Specifically, climate change has influenced the characteristics of spring discharges, evapotranspiration, snow-rainfall ratios, and snow seasonality, bringing new rainfall patterns associated with increased average air temperatures. Consequently, examining how groundwater storage mechanisms are changing in response to climate-driven has become crucial for understanding the future scenarios associated with water availability in such areas. Therefore, increasingly automated tools and simplified approaches need to be applied to continuously monitor hydrogeological variables affecting the spring recharge system. SOURCE (a semi-automatic tool for Spring mOnitoring data analysis and aqUifeR CharactErization) is an advanced semi-automatic Python tool that automates the hydrogeological characterization of the springs' aquifers. Its functionalities were tested through the analysis of the Promise and Alpe Perrot mountain springs and the related meteorological stations (La Thuile-Villaret and Champdepraz-Chevrere) located in the Aosta Valley region (NW Italy). Input data (flow rate, temperature, electrical conductivity, and rainfall) can be rapidly processed, providing graphical outputs, as well as values for the main hydrodynamic parameters (e.g. auto and cross-correlation coefficients) for an aquifer. Besides, to comprehend the relationship between changes in weather conditions and water availability in the Aosta Valley Region (Northwestern Italy), 7-year precipitation and discharge trends were considered. Despite the increasing trends in flow rate, considering the limited vulnerability values obtained for Alpe Perrot, it is possible to hypothesize a delayed impact of climatic changes on the spring system. The impact of climatic changes on Promise spring is supposed to be faster. However, the nature and dimensions of the aquifer are such as to be resilience to increasing water temperature. Being able to continuously monitor and define the effects induced on water reserves through simplified analysis approaches, such as those presented in this paper, is increasingly necessary, especially for local authorities. A single software package such as SOURCE that contains all the main methods of water spring analysis has the potential to significantly reduce any analysis times
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
