In a wireless sensor network (WSN) setting, this paper presents a distributed decision-making framework and illustrates its application in an online structural health monitoring (SHM) system. The objective is to recover a damage severity vector, which identifies, localizes, and quantifies damages in a structure, via distributive and collaborative decision-making among wireless sensors. Observing the fact that damages are generally scarce in a structure, this paper develops a nonlinear 0-norm minimization formulation to recover the sparse damage severity vector, then relaxes it to a linear and distributively tractable one. An optimal algorithm based on the alternating direction method of multipliers (ADMM) and a heuristic distributed linear programming (DLP) algorithm are proposed to estimate the damage severity vector distributively. By limiting sensors to exchange information among neighboring sensors, the distributed decision-making algorithms reduce communication costs, thus alleviate the channel interference and prolong the network lifetime. Simulation results in monitoring a steel frame structure prove the effectiveness of the proposed algorithms.

Due to the coronavirus disease 2019 pandemic, the new norm of online learning has been recognized as core to medical institutions for academic continuity, and students are expected to be motivated and engaged in learning while maintaining distance from other peers and educators. To facilitate students' and educators' newly defined roles in online medical education settings, it is crucial to understand how students are actively motivated and engaged in learning. Hence, this study explored medical students' motivational regulation profiles and examined the effects of motivational regulation strategies (MRS) on cognitive learning and learning engagement for online learning. Data were collected after the end of the first semester in 2020 from a sample of 334 medical students enrolled at a public university school of medicine. Latent profile analysis indicated three subgroups with different motivational regulation profiles: the low-profile, medium-profile, and high-profile groups. Regarding different MRS patterns in the high-profile group, mastery self-talk, performance approach self-talk, and the self-consequating strategy appeared to be most applicable for regulating learners' motivation. Analysis of variance showed that the profile groups with higher levels of MRS use were connected to a higher willingness to use cognitive learning strategies and a higher degree of engagement in online learning. The findings of this study emphasize the use of specific sets of MRS to support learning motivation and the need to design effective self-regulated learning environments in online medical education settings.

This study attempts to explain the unique patterns in Korean consumer behavior regarding the luxury fashion brands' donation activities by exploring the moderating effects of corporate ability (CA) and subjective norm (SN) on the relationship between donations and consumers' brand preference, brand trust, and purchase intention. A total of 209 completed questionnaires, collected from online surveys, were analyzed using moderated multiple regression. The result shows that donation amount information positively influences consumers' brand preference, brand trust and purchase intention toward luxury fashion brands. Next, CA strengthens the relationships between donation amount information and consumers' brand trust and purchase intention. SN from the opposite gender compensates for the negative effect of negative donation amount information on consumers' trust toward luxury fashion brands, whereas SN from the same gender does not influence those relationships. This study provides a deeper understanding of luxury fashion brands' donations and consumer responses in South Korea-one of the important test markets for luxury fashion brands to expand their business to Asian countries.

This study focuses on social norms and perceived benefits that are expected to lead to purchase fashion goods selling by social enterprises that can help guide the establishment of effective sales strategies for social enterprises. The relationships among two social norms (injunctive norms and descriptive norms), three perceived benefits (cause benefits, psychological benefits, and social image benefits), and purchase intention were investigated respectively. Data were collected via an online web survey and 11 hypotheses were statistically tested by using PLS-SEM analysis. Purchase intention toward the fashion products of social enterprises was influenced by four antecedent variables (injunctive and descriptive norms, cause and psychological benefits) excluding only social image benefits. However, descriptive norms only affected psychological benefits while injunctive norms only affected social image benefits. The findings suggest that the owners or marketers of social enterprises need to create a social atmosphere in which more consumers buy the fashion goods for social enterprises and emphasize consumers' psychological benefits that they feel mentally more comfortable by purchasing the fashion goods of social enterprises.

This study seeks to examine the effect of attitude, subjective norm, and perceived behavioral control on the purchase behavior of students enrolled in a private higher education establishment in Tangerang, Indonesia. This is a quantitative study and it employs samples by simple random sampling of 410 university students. The returned and valid questionnaire results totaled 261 samples. Data processing used the SEM method with SmartPLS 3.0 software. The findings of this study reveal that attitude, subjective norm, and perceived behavioral control have a significant effect on purchase intention. Meanwhile, purchase intention has a significant effect on working students' purchase behavior, and halal awareness had a moderating effect of purchase intention on purchase behavior. Purchasing interest has a positive effect on purchasing behavior, and this study proves that halal awareness is able to moderate the effect of purchase intention on purchasing behavior toward halal food products. The higher the awareness of halal products, the greater the relationship between buying interest and buying behavior of halal food. The results of this study also show the importance of paying attention to halal awareness factor in the form of increasing the relationship between buying interest and buying behavior of halal food products.

The study aims to identify factors that influence university and college students' entrepreneurial intentions in Vietnam's Mekong Delta region. The study examines entrepreneurship mindset, subjective norm, capital sources, concept development assistance, personality qualities, and perceived behavioral control of university support for a student's entrepreneurial aim. The research was conducted according to the quantitative method. The data was collected through an online survey with a sample size of 611 students from 19 universities and colleges in the Mekong Delta region. The methods that test the scale, including Cronbach Alpha Test, Structural Equation Modeling (SEM), are used to consider the correlation between the influence factors. The results of SEM analysis show that there are five main factors affecting students' entrepreneurial intention with decreasing level of influence, including the source of capital, perceived behavioral control, business development support, entrepreneurial attitude, and educational support. Besides, the results indicate that the subjective norm, personality traits, and concept development support have no impact on the intention of students toward entrepreneurship. The research also reveals that the entrepreneurial intention of students at universities and colleges has a positive relationship and is significantly affected by capital source and perceived behavioral control.
