Floods have always been an unavoidable natural disaster globally. Due to that, many efforts have been taken in order to alleviate the effect, especially in protecting the victims from losing their lives as well as their belongings. This study focuses on ensuring a smooth allocation process for flood victims to the relief centres considering the nature of their location, near the river, inland, and coastal. The finding indicated that a few implications have been highlighted for disaster management, such as changes in flood victim allocation patterns, classification of prone areas based on three areas, identification of most disaster areas, and others. Thus, to enhance the efficiency of allocation and to avoid any bad incidents happening during the flood occurrence, the allocation of flood victims is proposed to be started at a more critical area like the river area and followed by other areas. The finding also indicated that the proposed allocation procedure yielded a slightly lower average travel distance than the existing practice. These findings could also provide valuable information for disaster management in implementing a more efficient allocation procedure during a disaster.

The purpose of Vehicular Ad Hoc Network (VANET) is to provide users with better information services through effective communication. For this purpose, IEEE 802.11p proposes a protocol standard based on enhanced distributed channel access (EDCA) contention. In this standard, the backoff algorithm randomly adopts a lower bound of the contention window (CW) that is always fixed at zero. The problem that arises is that in severe network congestion, the backoff process will choose a smaller value to start backoff, thereby increasing conflicts and congestion. The objective of this paper is to solve this unbalanced backoff interval problem in saturation vehicles and this paper proposes a method that is a deep neural network Q-learning-based channel access algorithm (DQL-CSCA), which adjusts backoff with a deep neural network Q-learning algorithm according to vehicle density. Network simulation is conducted using NS3, the proposed algorithm is compared with the CSCA algorithm. The find is that DQL-CSCA can better reduce EDCA collisions.

The research aims to examine the determinants influencing the business commitment toward sustainable goals in Vietnam. To employ a quantitative research approach, we surveyed 208 business leaders in Vietnam to assess their perceptions and actions regarding sustainable goals. We explored the impact of internal enterprise characteristics and external facilitating factors on different dimensions of sustainable goals by using logistic regression models. This paper’s findings reveal that enterprise attributes, corporate leadership traits, and external factors significantly influence sustainable goal engagement. Notably, corporate leaders emerge as pivotal factors, particularly in their willingness to embrace risks and uncertainties. Moreover, this paper’s analysis identifies external factors with limited efficacy in fostering sustainable business operations. These insights hold significant implications for governmental institutions in Vietnam, offering valuable guidance for updating and refining policies.

Evaluating tourist destinations is extremely important as it is the basis for helping local authorities and the leadership of tourist destinations implement reasonable solutions to strengthen the state management of tourism, encourage investment and upgrade service quality at destinations, better exploit the tourist market, position the tourist destination brand in the international tourism market, increase the length of stay, and increase tourist spending when coming to the tourist destination. The current state of investment and development of tourist destinations means that tourist areas across the country need to be evaluated and classified to have a basis for encouraging investment and strengthening effective management, upgrading service quality at destinations, and gradually positioning the Vietnamese tourism destination brand in the international tourism market. This study evaluates the Ba Na tourist area (Da Nang city, Vietnam) based on the “Set of criteria for evaluating tourist destinations” issued by the Ministry of Culture, Sports and Tourism of Vietnam (2016). issued under Decision No. 4640/QĐ-BVHTTDL on 28 December 2016. Evaluation results show that criteria for tourism resources, landscape, facilities, participation of local communities, and the management of the tourist area are evaluated very well. On the contrary, services for entertainment, shopping, entertainment, and prices of services in the tourist area are limited problems in the Ba Na tourist area.

Using a qualitative research methodology and explanatory approach to collect data, we assessed whether the Beijing Consensus diplomacy in Africa is a promoter or threat to Africa’s pathway to sustainable development. The collected data were analysed using document and content analysis techniques. Analysis of the data revealed that the Beijing Consensus diplomacy in Africa is a positive initiative that has created a win-win situation, promoting sustainable development. The Beijing Consensus is opposed to the Washington Consensus, which influenced a win-lose situation that has deepened poverty, making Africa unable to move towards achieving sustainable development. The study found that China’s resource-for-development approach has similarities with pre-colonial Africa’s barter trade approach, which Africans practised in the entire continent. The analysis showed that applying the Beijing Consensus diplomacy to Africa has led to economic growth and development. The results showed that China’s Belt Road Initiative has transformed Africa, changing the continent from poverty to economic productivity, as road infrastructure is associated with economic growth and development. Moreover, it was evident from the analysis that without an African continental foreign policy rooted in continental sovereignty with transparent terms and conditions, Africa’s current benefits from China’s investments would lead to poverty instead of sustainable development. A continental foreign policy would create an African Consensus, which would act on behalf of the entire continent. This African Consensus diplomacy would thus become a continental foreign policy defining Africa globally. However, as it stands, the Beijing Consensus diplomacy is a promoter of sustainable development, but this promotion would not last long without African Consensus diplomacy. The study recommends that Africa should establish a continental foreign policy with African Consensus diplomacy to enable the continent to have one standard foreign policy and goal when trading with China and any other external world.

The study sheds light on how service quality aspects affect customer satisfaction in the Saudi banking sector’s particular socio-cultural setting. Thus, the study examines the role of service quality dimensions on customer satisfaction in the banking industry of Saudi Arabia. The study examined how reliability, assurance, empathy, tangibility, and responsiveness affect customer satisfaction in the Saudi Arabian banking market using 250 bank clients. 250 Saudi bank customers completed a standardised questionnaire. These were normal bank customers with proper bank accounts. IBM SPSS correlational and multiple regression analysis investigated variable connections. The study found a significant favourable influence of reliability on customer satisfaction. However, assurance was not significant. Empathy had a significant impact on customer satisfaction. Tangibility shown a significant impact on customer satisfaction. Responsiveness was not significant. The study emphasises on reliability, empathy, and physical service delivery to boost banking customer happiness. The study found 3 of 5 service quality factors to be significant predictors. Service empathy, tangibility, and reliability greatly impacted customer satisfaction. Managers in Saudi banking should prioritize reliability, empathy, and tangibility to boost customer satisfaction. To keep customers happy, managers should monitor these service quality dimensions and adjust strategies based on feedback. Technology can improve service quality by streamlining processes and personalizing experiences.
