The Journal of Information and Knowledge Management (JIKM) published its first issue in 2002 and celebrated its 19th birthday in 2020. This study aims to assess JIKM performance over its lifetime between 2002 and 2020 by extracting data from the Scopus database and using a combined approach of bibliometric and content analysis. More specifically, we evaluate JIKM’s productivity and stature, discuss its performance compared to other journals, and identify key contributing (authors, institutions, and countries), citation pattern, and conceptual structure. The results highlight JIKM’s growing presence, which is reflected in the dual rise of publication activity and accumulated citation. JIKM becomes one of the preeminent journals in the area of knowledge management, with a broad range of scientific actors’ contributions (authors, institutions and countries) from all over the world. Furthermore, using a bibliographic coupling, keywords’ analysis, and co-authorship analysis, we analyse JIKM’s content and identify the most frequent themes discussed. The analysis reveals that JIKM has expanded its scope from knowledge management to a new array of emerging technologies’ topics such as artificial intelligence and data mining. Graphical visualization of similarities (VOSviewer and Rstudio) shows that the major themes published are clustered into four groups, mainly (i) sustainable knowledge, (ii) emerging technologies, (iii) information management, and (iv) organization culture and knowledge sharing.

IntroductionNetwork meta-analysis (NMA) is a key methodology for comparing the effectiveness of multiple interventions or treatments simultaneously. This project aimed to ascertain current methods and visualizations for treatment ranking within an NMA framework and to subsequently develop a novel graphic within MetaInsight (an interactive NMA web application), to aid clinicians and stakeholders when making decisions regarding the “best” intervention(s) for their patient(s).MethodsCurrent literature on the methodology or visualization of treatment ranking published in the last 10 years was collated and studied. Based on the literature, a novel graphical visualization was developed using RShiny (RStudio, PBC) and integrated within MetaInsight, which is currently hosted on shinyapps.io.ResultsBayesian analyses produce rank probabilities from which mean or median rank and surface under the cumulative ranking curve can be calculated. For frequentist analyses the p-value is available. The simpler methods may be easier to interpret, but they are often more unstable and do not encompass the whole analysis (and vice versa). To aid interpretation and facilitate sensitivity analysis, an interactive graphic was developed that presents rankings alongside treatment effect and study quality results.ConclusionsTreatment ranking is useful, but the results should be interpreted cautiously, and the visualization should be transparent and all-encompassing. A ‘living’ version of MetaInsight, with treatment ranking, would allow interested parties to follow the evidence base as it grows.

Abstract The paper presents a new universal programmable portable measuring device (PMD) intended for the diagnostic and monitoring of hydraulic and pneumatic equipment. PMD offers a simple, complete, and efficient remote monitoring and diagnostic solution for hydraulic and pneumatic equipment. PMD is designed for measurement, recording, and processing of data as well as graphical visualization of registered results on a test stand or in the operating site of hydraulic and pneumatic equipment. PMD is designed to measure parameters used in servicing, repairing, monitoring, and diagnosing hydraulic and pneumatic equipment. Usually, fluidic characteristic quantities (pressure, flow rate, temperature), mechanical quantities (position, linear speed, rotational speed, force, torque, shaft power), and electrical quantities (voltage, current, power) is measured. PMD with WiFi communication is adopted to transfer measurement data via the Industry Internet of Things (IIoT) technology to remote online monitoring and diagnostic hydraulic and pneumatic equipment. Sensors, controllers, and other devices are connected to the computing gateway via their respective protocols.

The generalized [Formula: see text]–test is a test of item fit for items with polytomous responses format. The test is based on a comparison of the observed and expected number of responses in strata defined by the test score. In this article, we make four contributions. We demonstrate that the performance of the generalized [Formula: see text]–test depends on how sparse cells are pooled. We propose alternative implementations of the test within the framework of limited information testing. We derive the distribution of the [Formula: see text]–residuals that can be used for post hoc analyses. We suggest a diagnostic plot that visualizes the form of the misfit. The performance of the alternative implementations is investigated in a simulation study. The simulation study suggests that the alternative implementations are capable of controlling the Type-I error rate well and have high power. An empirical application concludes this article.

Circular drop manholes are widely implemented for steep catchments in urban drainage networks. Poor downstream hydraulic transition processes of a manhole system, i.e., the formation of hydraulic jump near the outlet entrance, and the sudden transition from free surface to pressurized flow with bursts of air in the outflow pipe can severely constraint the capacity of water conveyance. In this paper, we defined four basic hydraulic stages that indicate where hydraulic transition processes begin and end. The measurements of typical manhole models with different drop heights were conducted under different inflow and outflow conditions. Three types of transition processes covering all flow patterns have resulted into a graphical visualization by analyzing two pairs of dimensionless parameters. The flow inside a circular drop manhole was considered to reach its discharge capacity when the abrupt drop of manhole water level is visible in the fully aerated flow pattern. Four empirical equations revealing the water level filling ratio and discharge efficiency at different hydraulic stages were also presented for further predictions of choking risks.

Abstract RapGreen is a modular software package targeted at scientists handling large datasets for phylogenetic analysis. Its primary function is the graphical visualization and exploration of large trees. In addition, RapGreen offers a tree pattern search function to seek evolutionary scenarios among large collections of phylogenetic trees. Other functionalities include tree reconciliation with a given species tree: the detection of duplication or loss events during evolution and tree rooting. Last but not least, RapGreen features the ability to integrate heterogeneous data while visualizing and otherwise analyzing phylogenetic trees.

This paper presents a prototype for the visualization of food-drug interactions implemented in the MIAM project, whose objective is to develop methods for the extraction and representation of these interactions and to make them available in the Thériaque database. The prototype provides users with a graphical visualization showing the hierarchies of drugs and foods in front of each other and the links between them representing the existing interactions as well as additional details about them, including the number of articles reporting the interaction. The prototype is interactive in the following ways: hierarchies can be easily folded and unfolded, a filter can be applied to view only certain types of interactions, and details about a given interaction are displayed when the mouse is moved over the corresponding link. Future work includes proposing a version more suitable for non-health professional users and the representation of the food hierarchy based on a reference classification.

A table-graphical method for calculating the saturation time is proposed, which allows to optimize the process of selecting current transformers and relay protection devices connected to them to ensure their correct operation in transient ones, accompanied, among other things, by the occurrence of an aperiodic current component, to minimize errors, relying on table-graphical visualization.

Graphical visualization systems are a common clinical tool for displaying digital images and three-dimensional volumetric data. These systems provide a broad spectrum of information to support physicians in their clinical routine. For example, the field of radiology enjoys unrestricted options for interaction with the data, since information is pre-recorded and available entirely in digital form. However, some fields, such as microsurgery, do not benefit from this yet. Microscopes, endoscopes, and laparoscopes show the surgical site as it is. To allow free data manipulation and information fusion, 3D digitization of surgical sites is required. We aimed to find the number of cameras needed to add this functionality to surgical microscopes. For this, we performed in silico simulations of the 3D reconstruction of representative models of microsurgical sites with different numbers of cameras in narrow-baseline setups. Our results show that eight independent camera views are preferable, while at least four are necessary for a digital surgical site. In most cases, eight cameras allow the reconstruction of over 99% of the visible part. With four cameras, still over 95% can be achieved. This answers one of the key questions for the development of a prototype microscope. In future, such a system can provide functionality which is unattainable today.

Social entrepreneurship is a relatively novel topic and popular area of research and practice. It is recognised as a key instrument for addressing social issues and promoting sustainable development.The evolution of the social entrepreneurship concept has been discussed in the entrepreneurship domain last fifteen years.Therefore, a comprehensive inquiry of the overall body of knowledge relating tosocial entrepreneurship research in the entrepreneurship domain is vital for stimulating social entrepreneurship ecosystems. The research aims to support further study based on the current research trend through graphical visualization and bibliographic analysis. This study also maps the expansion of scientific and academic researchto explain the most recent stage in developing the phenomenon. It presents a general structure of the field and details of the main topics studied in this discipline. One thousand seven hundred sixty-three (1763) research papers published in the Scopus database from 1996 to 2019 were reviewed using bibliometric statistics covering 23 years.  Thus, the study, therefore, serves to map trends in the development of the research in this field. The results showed some useful insights, such as the pattern of annual publications, top citation-based authors, organizations, nations, and publishers worldwide. This paper will also provide a primary reference source for the researcher to establish a theoretical framework in this area.
