Purpose: In the landscape of global challenges, the adoption of new technologies and the implementation of intellectual capital are seen as the main vehicles to enhance banking operations. Inspired by this issue, our study is to discover the effect of technological investments and intellectual capital on one of the most important dimensions of banking operations, namely deposit intermediation. Research design, data and methodology: To tackle this concern, we utilize the data of 12 banks from 2011 to 2020 in Vietnam, and perform the multivariate regression analysis as well as provide different robustness tests. Results: Our empirical analysis demonstrates that a surge in technological expenditures would foster distribution of deposit intermediation of banks. Also, the blend of technology spending and intellectual capital plays a key role in boosting this function of banks. Conclusions: The study would bring one of new evidence for bank managers and national authorities in Vietnam, where has undergone the completely reform period in banking system. Accordingly, technological innovation and intellectual capital should be taken into consideration when managers and regulators build business strategies and related policies. The findings are also useful for nations bearing a close resemblance to Vietnamese financial system.

Purpose: This paper (1) identifies the factors that affect people's changing habits towards waste sorting, (2) evaluates the benefits of waste sorting to the environment and (3) designs communication strategies to change people's behavior and habits in sorting plastic waste in Ho Chi Mnh City, Vietnam. Research design, data and methodology: Using the data from 309 people that are living in Ho Chi Minh City and Structural Equation Modeling (SEM), to evaluate variables and test the hypotheses. Results: Research results show that attitudes, subjective standards, behavioral control, and facilities affect people's intention to classify plastic waste. We find that environmental concerns greatly influence people's attitudes. In contrast, environmental concerns have a relatively weaker effect on people's degree of behavioral control. Conclusion: Environmental protection is a matter of concern in the world. In Vietnam, this issue has been institutionalized into law to create a basis for improving the effectiveness of environmental protection activities. This article has some limitations. Firstly, sample is limited to HCMC residents; the study results are not representative of the entire population of Vietnam. This paper is based on cross-sectional data, which is not the best way to establish a causal relationship between the intention to sort plastic waste and its drivers.

How Does Intellectual Capital Fuel Non-Interest Incomes in Banks? New Case from an Emerging Country
Chi Huu Lu,Thich Van Nguyen World Association for Triple Helix and Future Stra 2023 Journal of Contemporary Eastern Asia Vol.22 No.1
The aim of this study is to answer the straightforward question of whether the implementation of IC has fueled non-interest incomes of banks or not. By utilizing the data of 26 domestic banks in Vietnam and employing the value-added intellectual coefficient model (VAIC) as the measure of IC efficiency, our empirical evidence manifests that IC plays a vital role in fostering non-interest incomes of banks. When dividing VAIC into different components, we find that structure capital employed (SCE) is the most important component to enhance the expansion of these incomes compared with other components including capital employed efficiency (CEE), human capital efficiency (HCE). These findings remain unchanged through some robustness tests performed. While the main driver of IC and SCE, CEE component becomes a substantial advantage to increase non-interest incomes in large banks. Meanwhile, the degree of impact of SCE is higher in small banks compared with large ones. Overall, this study would provide a deep insight into the role of IC in the transformation into non-interest income activities of banks in an emerging country, and therefore our findings would be useful for both scholars and policy-makers in Vietnam, where has undergone the period of major reforms in banking system.

In this paper, a robust adaptive control method based on Dynamic Structure Fuzzy Wavelet Neural Networks(FWNNs) system is presented for trajectory tracking control of industrial robot manipulators (IRM) withuncertainties and disturbances via adaptive sliding mode control (SMC). Four layer FWNNs in the Dynamic structureFWNNs is constructed on the basis of fuzzy rules which associates with wavelet function in the consequentpart, to compensate for structured and unstructured uncertainties and model complex processes. However, it isdifficult to design a suitable control scheme to achieve the required approximation errors, such as friction forces,external disturbances error and parameter variations. To deal with the mentioned problems, all the parameters of theDynamic structure FWNNs system are tuned on-line by an adaptive learning algorithm, and adaptive robust controllaws are determined by Lyapunov stability theorem. By using Dynamic structure FWNNs, this control systemcould achieve desired tracking performance, the stability and robustness of the closed-loop manipulators system areguaranteed. In addition, the simulations and experimental performed on a three-link IRM are provided in comparisonwith wavelet network control (WNC) and adaptive Fuzzy control (AFC) to demonstrate the effectiveness androbustness of the proposed Dynamic structure FWNNs methodology.
