Resilient marketing in hotel enterprises is a research area that has not been systematically explored. This study is based on the 4Ps theory to conduct a systematic theoretical study of resilient marketing in hotel enterprises and promote the application of resilient marketing in hotel enterprises. Data were collected from Chinese hotel employees (n = 501) through an online survey. Data were analysed using SPSS and AMOS software. confirmatory factor analysis (CFA) combined with structural equation modelling (SEM) was used to explore hotel employees’ perceptions of resilient marketing in hotel companies. The findings suggest that the concept of resilient marketing, constructed through the four dimensions of resilient products, resilient prices, resilient price, and resilient promotions, is better able to help hotel enterprises withstand crises. This study contributes to understanding how Chinese hotel enterprises use the concept of resilient marketing to withstand crises, such as positively adapting to market changes, collaboratively responding to market competition, and resisting and reversing crises situation. It has important theoretical value and practical significance for constructing a theory of resilient marketing for hotel enterprises, promoting the practical development of resilient marketing for hotel enterprises.

In order to diversify a portfolio, find prices, and manage risk, derivatives products are now necessary. There is a lack of understanding of the true influence of derivatives on the behavior of the underlying assets, their volatility consequences, and their pricing as complex instruments. There is a dearth of empirical research on how these instruments impact company risk exposures and inconsistent findings. This study examines corporate derivatives’ impact on stock price exposure and systematic risk in South African non-financial firms. Using a dataset of listed firms from 2013 to 2023, we employ Generalized Autoregressive Conditional Heteroscedasticity (GARCH) models to assess the effect of derivatives on return volatility and beta, a measure of systematic risk. Additionally, we apply the Generalized Method of Moments (GMM) to address potential endogeneity between firm characteristics and derivatives use. Our findings suggest that firms using derivatives experience lower overall volatility and reduced systematic risk compared to non-users. The results are robust to various control factors, including firm size, leverage, and macroeconomic conditions. This study fills a gap in the literature by focusing on an underrepresented emerging market and provides insights relevant to global risk management practices.

The Science and Technology Innovation Center holds a pivotal position in the national science and technology innovation system, and a scientific evaluation of the “Sci-tech Innovation Center” will guide its construction direction. This study found the advantages and disadvantages of the four cities through comparison; Hence improvement suggestions were proposed for the weaknesses of the four cities. There are two main paths for the government to drive technology innovation: STI (Science and Technology Innovation) mode and DUI (Doing, Using, Interacting) mode. With the aid of the evaluation index system of the Sci-tech Innovation Center, this article uses fuzzy sets, rough sets and fuzzy dynamic clustering methods to comprehensively evaluate the effects of driving technology innovation in the four cities of Beijing, Shanghai, Shenzhen and Guangzhou. The results found that Shenzhen has a significant effect in DUI, and Beijing has a significant effect in STI. The choice of path is related to the abundance of innovation resources.

Despite its leading role in the urban transport system, paratransit is accused of being unsustainable and hostile to modernity. The reform of the sector is necessary in the context of the modernization of the transport system of African cities. It requires the formalization of actors through technical and financial support such as fleet renewal projects. This article attempts to analyze the financing process and the level of formalism of the operators constituted within the AFTU in the context of the financing operation of paratransit operators in Dakar, Senegal. The methodological approach adopted is based on the analysis of qualitative data from questionnaire surveys carried out in the AFTU network in Dakar; official documents¹ were also used. The results show that the Dakar financing model put in place has made it possible to make significant progress in the reorganization of paratransit professionals. In addition to the concessioned lines, a salaried system was introduced, pricing is now official and the standardized ticketing system has been put in place. Nevertheless, improvements are expected on the working conditions of employees, the capacity building of actors and the evolution of the legal status of companies.

Adolescent childbearing is a crucial problem challenging policymakers in sub-Saharan African countries. The objective of this study is to show how teenage pregnancy and motherhood is related to social determinants like place of residence, education level and wealth quintiles, and consequently to suggest pragmatic actions susceptible to control the burden of teenage pregnancy. Disaggregated data were analyzed using data covering the decade 2012–2022 and provided by Demographic Health Surveys. In each country considered, the index of dissimilarity (ID) was computed to illustrate the variation of teenage pregnancy and motherhood according to the level of education, the rural-urban residence and the income quintiles. Recent statistics were also used for a comparison between countries. This study showed that childbearing affected 22.7% of African adolescents (15–19 years). However, the rate of adolescent childbearing varied from 40.4% in Nigeria to 5.2% in Ruanda. Moreover, huge differences were found in each country. Teenage girls living in rural areas, illiterate or with low level of education and suffering from poverty are more likely to be early married and to be exposed to pregnancy. The rate of adolescent childbearing is higher in Sub-Saharan African countries compared with countries from Latin America and World Health Organization Eastern Mediterranean. Most of the 31 countries considered in this study suffer from high rate of adolescent childbearing and large iniquities by place of residence and/or education level and/or wealth quintiles. Consequently, policymakers should adopt urgent and efficient strategies to reduce (and ideally to end) early marriage and teenage pregnancy by developing a policy that targets disadvantaged girls living in remote areas, having low or no decent income and suffering from illiteracy or low level of education.

The lack of attention from mining companies to the majority of areas still affected by mining activities can result in regional economic disparities and high levels of social violence. It is crucial to have policy strategies for mining contributions to rural development equity and social violence reduction through CSR assistance and other aid funds. This research employs the Multi-Criteria Decision Analysis method using the MULTIPOL analysis tool. Recommended action programs include the construction of schools, provision of scholarships, job openings, business capital, and infrastructure development, supported by strong regulations and law enforcement. Cracking down on illegal mining permits is essential to reduce environmental damage. Holistic and sustainable integration policies, alongside effective law enforcement, are necessary to achieve the goals of equitable development and social violence reduction. These steps should be reinforced with incentives for traditional/community leaders and increased police/military presence in villages within the next 2 years, particularly in zones 2 and 3 of the mining areas. Failure to implement these measures could escalate social violence, jeopardize security, and impede the operations of mining companies in Kolaka. The findings of this research support the priority of security and orderliness in development and underscore the importance of diverse research methods for mining area development policies.
