20. Eigenpairs of adjacency matrices of balanced signed graphs

Author

Chen Mei-Qin

Subjects
balanced signed graphs, structured adjacency matrix of a signed graph, eigenvalues and eigenvectors of an adjacency matrix, 15a18, 65f15, 05c50, 05c22, Mathematics, QA1-939
Abstract

In this article, we study eigenvalues λ\lambda and their associated eigenvectors xx of the adjacency matrices AA of balanced signed graphs. Balanced signed graphs were first introduced and studied by Harary to handle a problem in social psychology. Harary showed in 1953 that a signed graph is balanced if and only if its vertex set VV can be divided into two sets (either of which may be empty), XX and YY, so that each edge between the sets is negative and each within a set is positive. Based on this fundamental theorem for the balanced signed graphs, vertices of a balanced signed graph can be labeled in a way so that its adjacency matrix is well structured. Using this special structure, we find algebraically all eigenvalues and their associated eigenvectors of the adjacency matrix AA of a given balanced signed graph. We present in this study eigenpairs (λ,x)\left(\lambda ,x) of adjacency matrices of balanced signed graphs with some special structures.

21. Design and Evaluation of a Remote Synchronous Gamified Mathematics Teaching Activity That Integrates Multi-Representational Scaffolding and a Mind Tool for Gamified Learning

Abstract

Gamified learning is an instructional strategy that motivates students to learn, and the use of multiple representations assists learning by promoting students' thinking and advanced mathematical problem-solving skills. In particular, emergency distance learning caused by the COVID-19 pandemic may result in a lack of motivation and effectiveness in learning. This study designed an online gamified learning activity incorporating multi-representational scaffolding and compared the differences in the learning achievement and motivation for the gamified activity and general synchronous distance learning. In addition, for the group that conducted the gamified learning activity, we measured the participants' flow, anxiety, and emotion during the activity. A total of 36 high school students participated in the experiment. The results indicated that the gamified learning activity was not significantly effective in terms of enhancing learning achievement. In terms of learning motivation, a significant decrease in motivation was found for the group using general synchronous learning, while a significant increase in motivation was found for the group using synchronous gamified learning. This indicates that despite the negative impact of the pandemic on learning, gamified learning still enhances students' learning motivation. The results of flow, anxiety, and emotion showed that the participants had a positive and engaged experience. Participants provided feedback that the multi-representational scaffolding facilitates learning.

29. Identifying Struggles and Challenges Faced by Indonesian Migrant Workers Pursuing Higher Education in Taiwan

Author

Soraya, Siti Zazak and Chen, Mei-Ying

Abstract

People in social life often underestimated the presence of migrant workers caused by low skills and lack of education. The decision to continue higher education while working in the host country had tremendous challenges. This study aimed to develop a deeper understanding of the reasons, the problem encountered, and the learning strategies of migrant workers pursuing higher education at Indonesian Open Learning University of Taiwan ("Universitas Terbuka Taiwan"). There were 11 students participated in this study. This study was descriptive qualitative research, and the interactive model was applied in the analysis method. The data were gathered through in-depth interviews, participant observation, and documentation. The finding of this study revealed that: i) The migrant workers had the high motivation to pursue higher education because they wanted to change the stereotype that they were left behind and to seek a better life when they came back to Indonesia; ii) Inadequate time was the main problem to manage the study time due to the high workload; iii) The learning strategies of migrant workers were peer learning, group discussion, and note-taking. However, Indonesian Open Learning University of Taiwan was the excellent choice for the migrant workers in Taiwan to pursue higher education due to the flexibility of learning.

36. Research progress of sustained-release drug delivery system for uveitis

Abstract

Uveitis, a complex ocular disorder with numerous etiologies, can result from infection, autoimmune, and various physicochemical and mechanical injury factors. The treatment of this disease is difficult, and failure to receive timely and effective treatment can often lead to blindness. With the deepening of people's understanding of uveitis and its related mechanisms, various new sustained-release drug delivery systems for uveitis have been studied. However, due to the existence of various anatomical and physiological barriers in the eye, there are multiple obstacles to the sustained release treatment of uveitis. In this paper, the main research results in this field in recent years are reviewed, and the innovations and limitations of various new sustained-release drug delivery systems are discussed in order to provide new ideas for the sustained-release drug delivery treatment of uveitis in the future. These new sustained-release drug delivery systems will help to completely change the traditional treatment mode of uveitis with side effects and poor compliance in the future, bringing longer targeted sustained release and less toxic reactions.
