“…In recent years, many researchers have conducted scientometric analysis in different subject fields, including civil engineering. For instance, scientometric studies have been conducted on topics such as global Building Information Modeling (BIM) [16], [17], construction related ontology research [18], sustainability of megaproject management [19], urban resilience research [20] and water quality indexing [21].…”

Soft soils present significant challenges to infrastructure development worldwide due to high compressibility, low shear strength and low permeability. Bibliometric analysis remains scarce in the soft soil management field, making it difficult to grasp global trends and contributions. This research addresses this gap by providing a novel and comprehensive bibliometric analysis of soft soil management literature to investigate the trend, opportunities and challenges. The analysis predominantly examines ground improvement methods based on 2,260 journal articles and proceeding papers from WOS core collection between 2013 and 2023 using CiteSpace. The analysis encompasses country distribution, authorship and cocited authors, cited journals, reference co-citations and identification of research hotspots and frontiers. Findings show a growing interest and increased research focus in soft soil management, with China emerging as a prominent contributor. Reference co-citation clustering analysis reveals two dominant research themes: ground improvement methods (geosynthetic-reinforced embankments and stone columns) and sustainable practices (reuse of waste materials). The emerging word analysis reveals an evolutionary trend from investigating innovative and sustainable techniques to shear strength and failure mechanisms. Recent studies focus on the use of vertical drains, deep mixing columns, chemical stabilization, and sustainable ground improvement strategies. Opportunities lie in sustainable ground improvement methods and novel sensing technologies. Key challenges include bearing capacity, settlement, and slope stability. The study highlights the need for more research into two other key areas such as geotechnical characterization and foundation design. Overall, this bibliometric review contributes to a more thorough understanding of soft soil management studies for researchers and practitioners.

“…However, it is important to note that bibliometric analysis should be used in conjunction with other methods, such as a comprehensive literature review to provide a more comprehensive understanding of the topic [12]. Although bibliometric analysis is primarily used to study existing knowledge through trend analysis, co-occurrence networks and others, it can also be used to study the presence or absence of keywords to identify research gaps [13,14].…”

Identifying the Absence of Knowledge Using Bibliometric Analysis: The Case of the “Bad Behavior Index”

There are various hypotheses as to why some nations are more developed than others, including political instability, corruption, and exclusive institutions. However, one hypothesis that has not been extensively studied is the impact of 'bad behavior' on development. To test the validity of such hypothesis, a composite index must be developed to quantify such behavior, and facilitate for the study of its impact on development. This study aims to lay the foundation for the development of such index by conducting a bibliometric analysis of Scopus and Web of Science databases to determine if a quantitative measure of this concept already exists. This study employs a bibliometric and content analysis of these databases using Excel, VOSviewer, and R software. The results of such analysis indicate the absence of such a composite measure, thereby providing sufficient evidence that the construction of a 'Bad Behavior Index' is justified. Regarding the research contribution, the study offers an improved methodology for conducting bibliometric analysis by integrating and analyzing two journal databases instead of one, and using three different mediums and methods to identify the absence of knowledge, and provide a justification for the creation of such knowledge.

“…This is necessary to avoid “eclipsing”, which can occur when a number of parameters exceed the water quality guidelines [ 35 , 36 ]. At the same time, flexibility in defining the water quality index to be used is required, because over time, the mix of dominant pollutants or pollutants of interest might change [ 37 , 38 ]. For selecting the parameters included in the water quality index, the local hydrogeological conditions, climate, land use, anthropogenic influences, and the use of water resources have to be considered [ 20 , 39 ].…”

Groundwater, which is the main source of water for human consumption in many rural areas, has its quality determined by the complex interaction of environmental factors and anthropogenic activities. The present study evaluated the quality of shallow groundwater (1 to 25 m depth) in the rural area of the Târgovişte Plain, a densely populated area (200 inhabitants/km2) using 80 water samples collected from public wells. In order to explain the spatial distribution of the concentrations of the 19 physicochemical parameters considered (including heavy metals), the evaluation of groundwater quality for human consumption and potential impact on human health was conducted using the Water Quality Index (WQI), Integrated Weight Water Quality Index (IwWQI), Total Hazard Index (THI), and cumulative carcinogenic risk (CCR). For the WQI/IwWQI the comparative analysis of the two indices showed that for the WQI, it is important to select an optimal set of parameters, because use of a large number of physicochemical parameters can eclipse the values that exceed WHO guideline limits. In contrast, the use of entropy in the calculation of the IwWQI did not lead to eclipsing of exceedance, no matter the number of parameters used. Areas with poor and very poor groundwater quality according to the WQI/IwWQI overlapped, with a moderate risk to human health (THI > 1) for noncarcinogenic contaminants and also a risk of developing cancer according to the CCR average value (1.15 × 10−2). The health of 43% of the rural population in the Târgovişte Plain can be affected if they drink contaminated groundwater, and it is estimated that about 600 people can develop cancer during their lifetime. If the risk of developing cancer is reduced only in the rural population that does not have access to a water source from a centralized and verified network, the results suggest that 385 people (1.15%) can develop cancer as a result of consuming groundwater contaminated with heavy metals based on the average value of CCR. This value is lower than the general mortality rate in areas with high CCR and below the average number of cancer patients in Romania (2.65%). The quality of groundwater and the risk of developing diseases and cancer due to water consumption is directly proportional to the intensity of agricultural land use and inversely proportional to the depth of the groundwater layer, the distance from the main hydrographic network and the reservoirs, and the distance from the main city, Târgovişte. The complex and integrated analysis of groundwater quality using quality indices and indicators of health risk for the population, validated by hot-spot analysis and compared to the mortality rate, is an approach with practical applicability. This integrated approach allows public authorities, policymakers, and health services to implement an efficient monitoring program and optimize anthropogenic activities in order to prevent groundwater contamination and finally improve the quality of life for the residents in the area of this study.
