摘要： In real-world networks, such as social networks, the occurrence of random failures or external attacks on network components can lead to the discontinuation of information flow in the network. Hence, ensuring the existence and robustness of these networks is a crucial concern these days. To address this problem, one possible solution is to redesign the connection between individual nodes in the network using some budget-constrained rewiring operations. Multiple rewiring operations help in building trust between individuals and strengthening their connections, further enhancing overall connectivity and information flow in the network. The effectiveness of rewiring approaches is determined by analyzing some important facts, such as the rewiring cost, adherence to budget constraints, and enhancement in network connectivity. To assess the efficacy of rewiring approaches, the rewiring cost has been regularly updated after each rewiring operation by measuring the evolution of the size of the giant component in the social network. The performance of the proposed budget-constrained rewiring approaches is evaluated against the random rewiring approach. The results show the superiority of the proposed approaches on the benchmark real-world dataset. By leveraging these budget-constrained rewiring approaches, it becomes possible to design social systems that exhibit enhanced stability and reliability of social networks in the face of various disruptions.

摘要： 数字化时代,游戏正逐渐代替影视成为大众文化的一个占主导地位的媒介,从而在文化的全球传播中扮演越来越重要的角色。《黑神话:悟空》以现代的表达方式,将中国传统文化带入公众视野,迅速引发了社交媒体、文化产业、行业市场的广泛关注,制造了积极的经济和文化现象。不同媒介中的文学资源、文化符号和叙事风格被运用到数字游戏这一平台中,造就了这个规模宏大的跨媒介巨制。借由主支线设置、过场动画以及影神图等,游戏作品拟仿《西游记》原著所具有的章回体、散韵相间、说书人介入、多线叙事等文学特征,赋予古典诗学新的时代价值。现实世界中的自然与人文景观,经由中国艺术观念与技巧的创造性运用,在游戏的次级世界中得到重构,使得玩家感受到中华文化底蕴以及奇幻东方色彩。而汇聚不同媒介创作的故事世界在数字游戏这一平台中生成了具有集体意识和道德责任感的新英雄形象,以此挑战全球化浪潮中盛行的个人主义。《黑神话:悟空》在跨媒介生产与传播上已经取得了轰动效应,为新时代知识生产、文化产业以及中国文化全球传播提供了有价值的示范。

摘要： Over the previous 20 years, the software development industry has overseen an evolution in application of Version Control Systems (VCS) from a Centralized Version Control System (CVCS) format to a Decentralized Version Control Format (DVCS). Examples of the former include Perforce and Subversion whilst the latter of the two include GitHub and BitBucket. As DVCS models allow software contributors to maintain their respective local repositories of relevant code bases, developers are able to work offline and maintain their work with relative fault tolerance. This contrasts to CVCS models, which require software contributors to be connected online to a main server. Given this expansion in capabilities of productivity under the DVCS model, the Open-Source Software (OSS) development scene has transformed accordingly by moving to a DVCS system from the previous CVCS one. Previous work has shown that security breaches and bugs existing on any given application are patched more efficiently, albeit with occasional latency. Accordingly, many software development businesses in the contemporary industry require potential applicants to have knowledge of a VCS model of some sort for employment, with preference given to a DVCS model. Despite this necessity, many universities, including Murray State University, fail to introduce their students to any VCS system until the last year of their undergraduate experience in Computer Science during their work throughout their senior capstone project. Additionally, many students do not apply a VCS model until their senior capstone project as well. Preliminary review of articles written by major Github contributors supports that students who are permitted to conduct academic work on assignments within the Computer Science profession in their earlier years will likely have greater engagement with VCS products. Many developers in the machine learning field have shown great value in the community found through the VCS model they used and consequ

摘要： 20世纪初期的法国以独特的艺术气息而享誉世界。身为“迷惘的一代”代表作家的海明威与菲茨杰拉德,通过对法国自然景观与社会风土人情的描写,完成了对法国形象的整体性建构。小说主人公的经历不仅展现了其迷惘孤独的特征,也展现了“迷惘的一代”对美国传统道德回归的渴望。海明威与菲茨杰拉德巧妙地运用了法国文化的观照作用,表现出“迷惘的一代”对当世美国文化环境的反思,在异域书写中寄托了其对重振“美国信念”的诉求。

摘要： 随着Python程序设计语言类课程在高校开设的越来越普遍,尤其是该语言语法简单、易上手的特点,已成为非计算机类专业程序设计语言学习的首选,本文以国内某高校为例,分析了该校Python语言类课程的开课情况和课程建设的特点以及存在的问题,并提出了设计一款在线实验平台来解决上述问题,在实践的过程中,该平台表现出了良好的效果,同时积累大量相关教学数据,极大地推动了课程建设的进步。With the increasing prevalence of Python programming language courses in universities, especially due to the language’s simple syntax and ease of learning, it has become the preferred programming language for non-computer science majors. This paper takes a university in China as a case study to analyze the course offerings, characteristics of course construction, and the existing issues in Python language courses. The paper proposes the design of an online experimental platform to address these issues. In practice, the platform has demonstrated good results, while also accumulating a large amount of relevant teaching data, greatly promoting the progress of course development.
