This study aims to identify the growth pattern of research literature, most influential authors, most impactful documents and most relevant topics on sustainable development (SD) in higher education management (HEM) from 2000 to 2023.

The research approach used descriptive quantitative and bibliometric analysis. Scopus was used to retrieve data from 811 selected documents from 2000 to 2023. Data analysis used VOSviewer and R Biblioshiny.

The results showed intense development of sustainable development research in higher education management, especially in 2013–2023. Core literature was identified based on the volume of publications or citations from the perspective of authors, documents and keywords. Global research topics on SD in HEM focus on curriculum development and sustainable learning, sustainable higher education management and enhancing research and development of SD in HEM. The results of this research reveal the emerging intellectual structure in the field of educational management and provide reference points for academics who wish to study this discipline.

This study offers a valuable knowledge map for future research on sustainable development in higher education management. As a map, researchers can find core documents and current topics and identify potential research issues in this study.

This research examines the association of physical development density, prevalence and types of microbes in colonized façade finishes of buildings in Enugu metropolis, Nigeria.

Survey and experimental research designs were adopted. A total of 383 buildings were investigated with samples collected from those with colonized façade finishes. The microbes were identified using the standard procedure for genomic sequencing with descriptive statistics, and the chi-square test used to analyse the data.

The results revealed a 64% prevalence of microbial colonization and a significant association between this and physical development density with 71.0% of the colonized buildings located in high-density neighbourhoods of the metropolis. The sequencing also showed 24 different microbes with Trichophyton tonsurans, Trichophyton mentagrophytes and Trichoderma harzianum species being the most common in the colonized façade finishes.

The research informs building professionals and owners of the specific microbes involved in the colonization of façade finishes of buildings in high-density urban areas. It also provides a clue about the nature of damages and defects associated with microbial colonization of building façades and the type of biocide additives required for the production of microbial-resistant façade finishes in the hot-humid tropical environment of Nigeria and beyond.

The study has shown that there is a significant relationship between the intensity of urban land use and microbial colonization of façade finishes of buildings. It also identified some new or less known microbes responsible for the biodeterioration of façade finishes and the effects this has on the buildings and public health in the hot-humid tropics of Enugu, Southeast Nigeria.

The main objective of this study is to determine the factors that have the greatest impact on travelers' opinions of airports.

11,656 customer reviews for 649 airports around the world were gathered following the COVID-19 outbreak from the website that rates airport quality. The dataset was examined using hierarchical regression, PLS-SEM, and the unsupervised Bayesian algorithm-based PSEM in order to verify the hypothesis.

The results showed that people’s intentions to recommend airports are significantly influenced by their opinions of how well the servicescape, staff, and services are.

By encouraging air travelers to have positive intentions toward recommending the airports, this research offers airport managers decision-support implications for how to improve airport service quality. This will increase the likelihood of retaining more passengers.

This study also suggests a quick-to-implement visual decision-making mechanism based on PSEM that is simple to understand.
