    Understanding the impacts of overexploitation on the Salento aquifer: A Comprehensive review through well data analysis

    The Salento aquifer located in the Salento Peninsula in Southern Italy plays a vital role in supporting various sectors like agriculture, economy, and tourism. However, the aquifer has faced escalating challenges from rising water abstraction, falling piezometric levels, and saltwater intrusion for decades. This comprehensive review identifies the varied drivers of increased water abstraction like intensified agricultural activities and expanding tourism, through well data analysis, geological and hydrogeological studies, alongside evaluations of land use patterns, water consumption trends, and meteorological records. The study compares the findings of previous research, which have consistently shown a downward trend in the piezometric levels of the aquifer over several decades, confirming that this decline persists to the present day. The analysis of new and historical well data is combined with existing studies to explore the complex interactions between climate change and human impacts on the aquifer, providing general recommendations for sustainable aquifer management

    A Hydrological and Hydrochemical Study of the Gudiyalchay River: Understanding Groundwater–River Interactions

    The Gudiyalchay River plays a crucial role in the environment and human activities of the Guba area in north-eastern Azerbaijan, supporting agriculture and the local water supply. Despite its significance, the river has received little scientific attention. The groundwater beneath the Gudiyalchay riverbeds, a vital source of drinking water and the second primary source of river recharge after snowmelt, remains insufficiently studied, with most monitoring data being outdated. With climate change intensifying, such research is critical to mitigating potential water risks. In this work, all available geological, hydrogeological, climatic, and hydrochemical data were collected to characterize the study area and analyze the seasonal fluctuations in river flow and total dissolved solid (TDS) values, with a focus on the interactions between the river and groundwater at the Khinaliq, Giriz, and Kupchal flow stations. The analysis shows that both river and groundwater TDS values are within acceptable drinking water limits, but continuous data collection is important to confirm this. Flow rate analysis and a literature review revealed that variations in flow rate are linked to seasonal changes, with the flow rate near the Giriz station indicating potential groundwater influence. Based on the literature review and analysis, a simplified hydrogeological diagram is created to provide a clearer understanding of the interactions between the river and groundwater systems

    Use of Project-Based Learning in Preparation of Education Managers: Case of Post-Soviet Azerbaijan

    This study explores the implementation of Project-Based Learning (PBL) in Master of Education Management Programs in two Azerbaijani universities. The aim was to find out if the sample universities integrate projects into their programs using a systematic PBL model. Interviews with the faculty and administration were conducted and the curricula of programs were scrutinized to assess the level of the consistency in the subjects on offer. Although the courses in both programs are quite suitable for PBL integration, only in one of the sample universities was there evidence of extensive use of projects, albeit mainly in a single assignment level. The results show that Azerbaijani universities need to develop a well-structured PBL model adapted to the local context. The results of the interviews emphasize the crucial role of PBL in the acquisition of employable skills and competences in education management. Major limitations in the process of PBL implementation include a lack of awareness about PBL, inadequate organizational support in the form of staff trainings, the provision of facilities and negotiations with stakeholders.   &nbsp

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    Get PDF
    We 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

    Get PDF
    We 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 text
    We 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
