Using structural equation modeling, this study empirically examined the causal relationships among the level of advanced manufacturing technology (AMT), facilitation of alignment, the degree of strategic alignment of management eccounting Information systems (MAIS), and the improvement of production performance. The causal relationships between MAIS strategic alignment and information characteristics of MAIS were also investigated. The results showed that the level of AMT has a significant and positive impact on alignment facilitation. A significant causal relationship between alignment facilitation and MAIS strategic alignment was also found. It was shown that under high degrees of MAIS strategic alignment, MAIS must provide broad-scope and integrated types of Information. The causal relation-ships between MAIS strategic alignment and organizational performance were significant and positive. Thus, it is concluded that under high levels of AMT, a high degree of MAIS strategic alignment positively contributes to the improvement of production performance.

This paper presents the evaluation of the impact of climate change on water resources and yield capacity of Asa and Kampe reservoirs. Trend analysis of mean temperature, runoff, rainfall and evapotranspiration was carried out using Mann Kendall and Sen's slope, while runoff was modeled as a function of temperature, rainfall and evapotranspiration using Artificial Neural Networks (ANN). Rainfall and runoff exhibited positive trends at the two dam sites and their upstream while forecasted ten-year runoff displayed increasing positive trend which indicates high reservoir inflow. The reservoir yield capacity estimated with the ANN forecasted runoff was higher by about 38% and 17% compared to that obtained with historical runoff at Asa and Kampe respectively. This is an indication that there is tendency for water resources of the reservoir to increase and thus more water will be available for water supply and irrigation to ensure food security.

The popularity of Social Network Service (SNS) providing web sites has increased continuously by using a variety of mobile devices. The study results show that security of SNS, efficiency of SNS, safety, empathy of SNS quality, easy of use of SNS, assurance of SNS, service variety of SNS are having positive impact to some degree on the user satisfaction. Further, the user satisfaction of SNS users have a positive impact on the continuance usage intention of SNS users. This results show that various SNS qualities are necessary to actively explore and obtain further information that users intend to find, while they are insufficient in function to provide the information other users require or exchange information with other users through the SNS.

The purpose of this study is to investigate two components of commitment(affective commitment and calculative commitment) and relational equity on loyalty. In addition, The authors analyzed the moderating effect of length of relationship on the effects of commitments and relational equity on switching intention. Major findings can be summarized as follows. It was found that affective commitment made a negative impact on switching intentions and a positive impact on w-o-m. Calculative commitment had no effect on switching intention and w-o-m while it made a negative effect on w-o-m in handset side only. Relational equity appears to bolster a negative effect on switching intention and a positive effect on w-o-m. Also length of relationship seems to moderate the effect of relational equity on switching intention.

Negative bias temperature instability (NBTI) and positive bias temperature instability (PBTI) are critical circuit reliability issues in highly scaled CMOS technologies. In this paper, we analyze the impacts of NBTI and PBTI on SRAM $V_{MIN}$, and present a design solution for mitigating the impact of NBTI and PBTI on SRAM $V_{MIN}$. Two different types of SRAM $V_{MIN}$ (SNM-limited $V_{MIN}$ and time-limited $V_{MIN}$) are explained. Simulation results show that SNM-limited $V_{MIN}$ is more sensitive to NBTI while time-limited $V_{MIN}$ is more prone to suffer from PBTI effect. The proposed NBTI/PBTI-aware control of wordline pulse width and woldline voltage improves cell stability, and mitigates the $V_{MIN}$ degradation induced by NBTI/PBTI.

The purpose of this study is to investigate the impacts of e-service quality factors on customer satisfaction and behavior intention. Difference and moderating effect resulting from the type of web site users about an association with reaction of satisfaction and those component concepts are also one of the aims in the study. As the results, the study found that factors of web site service quality variables has a positive impact on customer satisfaction. And customer satisfaction also has a positive impact on relationship intention and word of mouth intention. According to those results, marketing managers should develop different service strategies.

Public information arrivals and their immediate incorporation in asset price is a key component of semi-strong form of the Efficient Market Hypothesis. In this study, we explore the impact of public information arrivals on cryptocurrency market via Twitter posts. The empirical analysis was conducted through various methods including Kapetanios unit root test, Maki cointegration analysis and Markov regime switching regression analysis. Results indicate that while in bull market positive public information arrivals have a positive influence on Ripple's value; in bear market, however, even if the company releases good news, it does not divert out the Ripple from downward trend.

The construction and real estate industries contribute significantly to each country's economic development. Strong construction and real estate firms will contribute more to the country's GDP by contributing to the industry's development. The purpose of this study is to examine the factors that influence the performance of the construction and real estate sectors in Vietnam. A survey of 200 construction and real estate firms in different areas was conducted from 2020 until the end of 2021. Following the removal of errors, the author got 196 replies, 6 of which were invalid, leaving 190 votes for quantitative analysis. The research findings show that elements such as (1) senior executives' commitment to the organization, and (2) the ability to use technology have a positive and significant impact on firm performance when using advanced econometric analysis. Furthermore, in the case of Hanoi, Vietnam, business relationships have a positive impact on firm performance. Training and development, as well as the working environment and incentives, have little effect on the profitability of construction and real estate firms. Finally, the research also has some recommendations and limitations for the construction and real estate sector.

Considering that extant studies on safety behavior have paid insufficient attention to the impact of corporate social responsibility(CSR) on employee's safety behavior. This paper delves into the influence of CSR on safety behavior and its intermediating mechanism such as mediator and moderator. To be specific, the current paper examines the mediating effect of employee's psychological safety in the CSR-safety behavior link, also investigating the moderating effect of ethical leadership in the relationship between CSR and psychological safety. As expected in the hypotheses, the results showed that that CSR has a positive (+) influence on psychological safety, which has a positive (+) impact on safety behavior. Also, employee's psychological safety mediated the association between CSR and safety behavior. Lastly, ethical leadership moderated the CSR-psychological safety link.
