For improving the performance and effectiveness of peer review, a novel review system is proposed, based on analysis of peer review process for academic journals under a parallel model built via Monte Carlo method. The model can simulate the review, application, and acceptance activities of the review systems, in a distributed manner. Simulation ex...

Screenshots are ubiquitous in mobile computing, yet poorly understood. This paper advances our understanding of reasons for capturing, storing, and sharing screenshots. A crowdsourced user study was conducted where 52 participants shared personal screenshots from their phones, alongside textual reasons for why they were captured. Using mixed method...

Prior studies have shown the importance of classroom dialogue in academic performance, through which knowledge construction and social interaction among students take place. However, most of them were based on small scale or qualitative data, and few has explored the availability and potential of big data collected from online classrooms. To addres...

The dynamics of academic journals are observable from time series of citation indices, such as journal impact factor (JIF), which are quantitative emergence of the citation network topology ever growing. It is meaningful to study the variation of citation indices and quality of journals through computational studies. In this article, an experimental system is developed to generate virtual citation networks by simulating key social activities, including manuscript submission, peer review, journal publication, and article citation. The system is built upon a model grounded solely in basic individual behavioral dynamics and free from reliance on specific technical assumptions, ensuring broad generality. By incorporating bibliometric attributes such as article quality scores and temporal publication data, the system enables replication of journal behaviors and citation dynamics. A series of computational experiments are conducted on the system, revealing and analyzing various phenomena under different scenarios. Key findings include the identification of dynamic patterns such as stationarity, inertia, and polarization tendencies in journal performance over time. The experiments further demonstrate the robustness of journal dynamics against moderate external disturbances, such as self-citation behavior, and highlight a gradual weakening of volatility in journal citation indices. These findings are further explained through a semianalytical approach. The study offers actionable insights for journal management, policy design, and long-term evaluation strategies, contributing to a deeper understanding of the temporal evolution of academic journal communities.
Computer model has been extensively adopted to overcome the time limitation of language evolution by transforming language theory into physical modelling mechanism, which helps to explore the general laws of evolution. In this paper, a model is designed to simulate the evolution process of languages in human settlements, with the associated network topology being lattice. The language of each node in the lattice will evolve gradually under the influence of its own fixed evolutionary direction and neighbours. According to the computational experiment results, it is discovered that the state points of languages always converge into several clusters during the evolution process, which gives us an insight into language evolution.
