GIS-Based Assessment Model of Resilient Management and Monitoring of Water Resources
Full text linkIntroduction. The management and efficient use of water resources is a crucial and extremely acute problem. This study focuses on geographic information systems (GIS) as a tool for the resilient management and monitoring of water resources. The objective was to create and implement a GIS-based model for managing and monitoring water resources by developing a system of indicators. This model presents future scenarios for Bulgaria based on the assessment of indicators for resilient management and the efficient use of water resources.
Aim and tasks. This study aims to develop and implement a GIS-based model that integrates technical, economic, social, and environmental indicators for the resilient management and monitoring of water resources in Bulgaria. This study focuses on opportunities to improve the effective management and rational allocation of water resources in Bulgaria using geographic information systems.
Results. A comprehensive system of indicators for assessing sustainable water management in Bulgaria was developed, considering economic, technical, social, and environmental criteria. The calculation of the composite index showed a low level of efficiency, and the main problems were water losses during transportation of up to 55-60%, a reduction in investments in wastewater disposal by 40% (2016-2023) and a low level of reuse of treated wastewater. The GIS-based model revealed significant territorial differences in the state of water resources and consumption in Bulgaria. Key problems include high losses in the water supply network, water use for hydropower, and poor water infrastructure, which affect the resilience of water management. Irrational consumption and storage may lead to serious water supply issues in key regions of the country.
Conclusions. Geographic information systems enable the improvement of water resource management by integrating and processing large amounts of data. In response to the identified research questions, the current state of Bulgaria’s water sector was analysed and assessed. The key factors affecting the sustainable management and use of water resources and territorial imbalances in rational water use were identified. Developing a comprehensive strategy that includes infrastructure modernisation, introducing water-saving technologies and improved management efficiency can overcome structural problems in the water sector and prevent water resource shortages
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
Assessing Employee Perceptions of Information Technologies in Public Sector Digitalization
Full text linkIntroduction. The increasing role of digitalisation in the public sector is caused by the possibility of improving the quality of public services. However, the effective implementation of digitalisation in public organizations and its use is influenced by technological, organizational, environmental and human factors. Therefore, it is relevant to assess the perception of employees of government bodies and their perception of using information systems and technologies.
Aim and tasks. The goal is to study the resilience of public organisations and employee reactions in crises using information systems. The stated goal determined the survey of employees’ opinions on the effects of the implementation and use of information and communications technology (ICT) in terms of improving communication and coordination in the organisation, crisis response capabilities, and satisfaction with the use of the system.
Results. The study analysed the responses of representatives of various public administration and administrative management levels in Bulgaria, the results of which were analysed using IBM SPSS Statistics. The survey involved 73 employees of public organisations holding various positions, which made it possible to assess the perceptions and impact of ICT use by employees. In the context of this study, it has been proven that information systems technology supports communication and coordination in public organisations. This affects the system’s perceived usefulness and the employees’ handling of unexpected changes (crises). Resolving crises using information and communication technologies affects employee satisfaction, which contributes to increasing organisational resilience.
Conclusions. This study examines the attitude of employees working in public administration toward the use of information and communication systems and the strengthening of the digitalisation process. Based on rank correlation analysis, research hypotheses were proven. It was found that there is a relationship between the use of ICT, improved organisational coordination and communication, crisis management and satisfaction of public sector employees with the use of ICT. The above factors affect organisational resilience and the ability to adapt in the context of digital transformation
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
