The influence of CEO characteristics on corporate environmental performance of SMEs: Evidence from Vietnamese SMEs

Drawing on upper echelon theory, this study investigates the impact of CEOs’ (chief executive officers) demographic characteristics on corporate environmental performance (CEP) in small and medium-sized enterprises (SMEs). We hypothesized that CEO characteristics, including gender, age, basic educational level, professional educational level, political connection, and ethnicity, affect SMEs’ environmental performance. Using the cross-sectional data analysis of 810 Vietnamese SMEs, this study provides evidence that female CEOs and CEOs’ educational level (both basic and professional) are positively related to the probability of CEP. We also find that based on the role of institutional environment on CEP, political connections had a negative effect on CEP in the context of Vietnam. Another finding is that SMEs with chief executives from ethnic minority groups show a higher level of the probability of corporate environmental performance than companies operated by Kinh chief executives. Since CEP is an essential dimension of corporate social responsibility, a strategic decision for SMEs, it is crucial for the company to select appropriate CEOs based on their demographic characteristic

Spectral properties of the surface reflectance of the northern polar region of Mercury

We analyse MESSENGER reflectance measurements covering the northern polar region of Mercury, the least studied region of the northern mercurian hemisphere. We use observations from the Mercury Dual Imaging System Wide-Angle Camera (MDIS/WAC) and the Mercury Atmospheric and Surface Composition Spectrometer (MASCS/VIRS) to study the spectral dependence of the surface reflectance. The results obtained from the observations made by both instruments are remarkably consistent. We find that a second degree polynomial description of the measured reflectance spectra gives very good fits to the data and that the information that they carry can best be characterized by two parameters, the mean reflectance and the mean relative spectral slope, averaged over the explored range of wavelengths. The properties of the four main types of terrains known to form Mercury's regolith in the northern region, smooth plains (SP), heavily cratered terrain (HCT), fresh ejecta/materials and red pitted ground (RPG) are examined in terms of these two parameters. The results are compared, and found consistent with those obtained by earlier studies in spite of difficulties met in obtaining accurate reflectance measurements under the large incidence angle condition characteristic of polar regions. These results will help with the preparation of the BepiColombo mission and with supporting its observational strategy.Comment: 21 pages, 15 figures, accepted for publication in Research in Astronomy and Astrophysic

Intra-organizational knowledge transfer process in Vietnam's information technology companies

Intra-organizational knowledge transfer has attracted much attention of researchers and practitioners in recent years since knowledge transfer has been considered as a critical determinant of an organization’s capacity to confer sustainable competitive advantage. Despite extensive research on knowledge transfer issues, the effect of knowledge transfer on organizational performance still has not been fully examined or attracted adequate empirical testing. Therefore, the objective of this study is to investigate organizational factors influencing intra-organizational knowledge transfer, and examine the relationship between knowledge transfer process, its antecedents and organizational performance. Drawing on several theoretical streams, an integrated theoretical model of intra organizational knowledge transfer together with 13 hypotheses were developed and tested in the context of IT companies in Vietnam. To achieve the objectives, a triangulation of quantitative and qualitative studies was applied. A quantitative survey was employed to test hypotheses in the conceptual model derived from relevant literature. Data were collected from a survey of 218 managers and technical staff working in 36 IT companies located in Hanoi and HoChiMinh City. Multiple regression techniques were used to analyze the data. A case study research was conducted with the aim of illustrating the intra organizational knowledge transfer process within a company operating in a transition economy like Vietnam. Data for case study were mainly collected by interviewing managers and technical staff during a one-month field study in the FPT Software Solutions Company. The main findings showed that intra-organizational knowledge transfer is most affected by organizational culture, incentive system and organizational structure. Adaptability and solidarity are two culture values enabling the transfer process. A transparent and flexible incentive system motivates individuals to exchange and apply knowledge in their daily work. High level of centralization creates difficulties for social interaction and reduces autonomy and active involvement of employees, vi which are essential for successful knowledge transfer. High formalization facilitates the knowledge transfer process by providing a clear direction for employees and enhancing communication flow through an extensive monitoring and reporting requirement. The frequency of using IT tools did not significantly influence the intra organizational knowledge transfer process after other independent variables were added in the regression model. This suggests either that IT tools may not directly itself is not enough to ensure successful knowledge transfer. Therefore, to facilitate knowledge transfer process, it is important to foster knowledge-sharing attitude through providing greater opportunities for deeper involvement of users in the system. Although the knowledge transfer process was found not to mediate the relationship between its antecedents and organizational performance, the process itself moderately predicts organizational performance. This suggests that intra organizational knowledge transfer process should be considered as one of the factors contributing to company performance. The research has filled gaps in existing literature in several ways. Firstly, it extends our understanding of the important facilitators of intra-organizational knowledge transfer process. Secondly, it attempts to integrate both soft and hard organizational factors to create a comprehensive model of intra-organizational knowledge transfer. Thirdly, it clarifies the role of the intra-organizational knowledge transfer process in improving the company’s performance in a transition economy. Overall, the results of the study contribute to the advancement of research in the area of intra-organizational knowledge transfer and provide practical implications for managers of IT companies in Vietnam by shedding light on determinant factors of knowledge transfer process and examining the link between knowledge transfer process and firm performance

Digital Reference Evaluation: Assessing the Past to Plan for the Future

Historically, libraries have routinely evaluated their reference services both quantitatively and qualitatively. With the increasing volume of digital reference transactions, there is a need to modify and apply to digital reference, the same evaluation techniques that have been used successfully in the evaluation of traditional reference service. At Southeastern Louisiana University, a recent evaluation of the library\u27s Ask a Librarian digital reference service included an unobtrusive observation of current practice through a detailed examination of archived reference transactions, as well as an assessment of future needs through a survey of users. Through this evaluation, it was possible to assess the effectiveness of the library\u27s e-mail reference service, as well as to plan for the implementation of a new real-time digital reference service

Blended Learning for Secondary Schools in Nam Dinh Province to Satisfy New Standards: The Current Situation and Proposed Models

We offered blended learning models for high schools in Nam Dinh province to satisfy Vietnam's new criteria. These models were based on general approaches to issues, theoretical research, and field research based on surveys and anket questionnaires conducted throughout the area. The results of a survey demonstrate that high school teachers in Nam Dinh have gained a fundamental grasp of blended learning and have, in practice, embraced both online and face-to-face instruction, particularly during the height of the Covid-19 outbreak. However, there was not a standard model for blended learning, therefore it was only used by a few persons. In other contexts, the concept of "blended learning" referred to what was effectively a face-to-face session that was broadcast over the Internet without the necessary adjustments being made to the content, methodology, or evaluation. As a result, we offer a number of different ways to blended learning for high schools in Nam Dinh in order to improve the quality of education provided throughout the province

Numerical modeling of thermal dust polarization from aligned grains in the envelope of evolved stars with updated POLARIS

Magnetic fields are thought to influence the formation and evolution of evolved star envelopes. Thermal dust polarization from magnetically aligned grains is potentially a powerful tool for probing magnetic fields and dust properties in these circumstellar environments. In this paper, we present numerical modeling of thermal dust polarization from the envelope of IK Tau using the magnetically enhanced radiative torque (MRAT) alignment theory implemented in our updated POLARIS code. Due to the strong stellar radiation field, the minimum size required for RAT alignment of silicate grains is $\sim 0.005 - 0.05\,\rm\mu m$. Additionally, ordinary paramagnetic grains can achieve perfect alignment by MRAT in the inner regions of $r < 500\,\rm au$ due to stronger magnetic fields of $B\sim 10$ mG - 1G, producing thermal dust polarization degree of $\sim 10\,\%$. The polarization degree can be enhanced to $\sim 20-40\%$ for grains with embedded iron inclusions. We also find that the magnetic field geometry affects the alignment size and the resulting polarization degree due to the projection effect in the plane-of-sky. We also study the spectrum of polarized thermal dust emission and find the increased polarization degree toward $\lambda > 50\,\rm\mu m$ due to the alignment of small grains by MRAT. Furthermore, we investigate the impact of rotational disruption by RATs (RAT-D) and find the RAT-D effect cause a decrease in the dust polarization fraction. Finally, we compare our numerical results with available polarization data observed by SOFIA/HAWC+ for constraining dust properties, suggesting grains are unlikely to have embedded iron clusters and might have slightly elongated shapes. Our modeling results suggest further observational studies at far-infrared/sub-millimeter wavelengths to understand the properties of magnetic fields and dust in AGB envelopes.Comment: 27 pages, 23 figures, 1 table, to be submitte
