1. Effects of governmental data governance on urban fire risk : a city-wide analysis in ChinaZhao-Ge Liu, Xiang-Yang Li, Grunde Jomaas, 2022, original scientific article Abstract: The effects of data governance (as a means to maximize big data value creation in fire risk management) performance on fire risk was analyzed based on multi-source statistical data of 105 cities in China from 2016 to 2018. Specifically, data governance was first quantified with ten detailed indicators, which were then selected for explaining urban fire risk through correlation analysis. Next, the sample cities were clustered in terms of major socio-economic characteristics, and then the effects of data governance were examined by constructing multivariate regression models for each city cluster with ordinary least squares (OLS). The results showed that the constructed regression models produced good interpretation of fire risk in different types of cities, with coefficient of determination (R2) in each model exceeding 0.65. Among the indicators, the development of infrastructures (e.g. data collection devices and data analysis platforms), the level of data use, and the updating of fire risk related data were proved to produce significant effects on the reduction of fire frequency and fire consequence. Moreover, the organizational maturity of data governance was proved to be helpful in reducing fire frequency. For the cities with large population, the cross-department sharing of high-value data was found to be another important determinant of urban fire frequency. In comparison with existing statistical models which interpreted fire risk with general social factors (with the highest R2 = 0.60), these new regression models presented a better statistical performance (with the average R2 = 0.72). These findings are expected to provide decision support for the local governments of China and other jurisdictions to facilitate big data projects in improving fire risk management.

2. Soil contamination in nearby natural areas mirrors that in urban greenspaces worldwideYu-Rong Liu, Marcel G. A. van der Heijden, Judith Riedo, Carlos Sanz-Lazaro, David J. Eldridge, Felipe Bastida, Eduardo Moreno-Jiménez, Xin-Quan Zhou, Hang-Wei Hu, Ji-Zheng He, Tine Grebenc, Tina Unuk Nahberger, 2023, original scientific article Abstract: Soil contamination is one of the main threats to ecosystem health and sustainability. Yet little is known about the extent to which soil contaminants differ between urban greenspaces and natural ecosystems. Here we show that urban greenspaces and adjacent natural areas (i.e., natural/semi-natural ecosystems) shared similar levels of multiple soil contaminants (metal(loid)s, pesticides, microplastics, and antibiotic resistance genes) across the globe. We reveal that human influence explained many forms of soil contamination worldwide. Socio-economic factors were integral to explaining the occurrence of soil contaminants worldwide. We further show that increased levels of multiple soil contaminants were linked with changes in microbial traits including genes associated with environmental stress resistance, nutrient cycling, and pathogenesis. Taken together, our work demonstrates that human-driven soil contamination in nearby natural areas mirrors that in urban greenspaces globally, and highlights that soil contaminants have the potential to cause dire consequences for ecosystem sustainability and human wellbeing.

5. Fo Guang Shan's Expansion in the Religious Market of Thailand : a SWOT analysisGuiyu Su, Yaoping Liu, 2022, original scientific article Abstract: As one of the prominent Mahayana Buddhist institutions from Taiwan, Fo guang Shan (FgS) entered the religious market of Thailand as early as the 1990s. Its influence has grown tremendously among the local Chinese communities and Thai society. Despite this, there is a dearth of scholarship dedicated to FgS’s mar-ket expansion in Theravada-dominated Thailand. Through a SWOT analysis, this paper explores FgS’s marketing strategy for the Thai religious market. The findings suggest that FgS bears certain strengths, such as its appealing humanistic Budd-hist doctrine, gift-giving networking skills and its strong emotional bonds with the Chinese communities in Thailand. These strengths have brought and will conti-nuously provide FgS with opportunities for further expansion. However, FgS’s weakness is always there and obvious, given its foreign and non-mainstream na-ture and questionable legitimacy of existing as a Buddhist institution (or temple) in Thailand. All this has already caused threats to FgS’s missionary clergies and sanctuaries, mainly based in the Bangkok area, not to mention the growingly fierce competition from its Thai Theravada and local-born Mahayana counterparts.
