摘要： Identifying key structures from social networks that aims to discover hidden patterns and extract valuable information is an essential task in the network analysis realm. These different structure detection tasks can be integrated naturally owing to the topological nature of key structures. However, identifying key network structures in most studies has been performed independently, leading to huge computational overheads. To address this challenge, this paper proposes a novel approach for handling key structures identification tasks simultaneously under the unified Formal Concept Analysis (FCA) framework. Specifically, we first implement the FCA-based representation of a social network and then generate the fine-grained knowledge representation, namely concept. Then, an efficient concept interestingness calculation algorithm suitable for social network scenarios is proposed. Next, we then leverage concept interestingness to quantify the hidden relations between concepts and network structures. Finally, an efficient algorithm for jointly key structures detection is developed based on constructed mapping relations. Extensive experiments conducted on real-world networks demonstrate that the efficiency and effectiveness of our proposed approach.

摘要： This panel of presenters, with over 80 years of teaching instruction between them, will share with attendees a variety of actual tools, toys, and/or visuals that have helped students understand concepts in the programming sequence, i.e. CS 1, CS 2, CS 7 (algorithms) classes. These are based on moments in the classroom when students have reported that new or difficult concepts were made easier to learn.

摘要： The foundational aspects of computer science are usually explained with mathematical models such as Finite Automata (FA), Pushdown Automata (PDA) and Turing Machines (TMs). Challenges of teaching mathematical foundations can be overcome with innovative approaches and agile planning. For undergraduate students, teachers should start with a general overview of the area so that students get the big picture and become interested in learning more about foundational ideas and their relationships. Active participation of students should be encouraged from the beginning when the basic ideas are introduced. At the initial stages, proof ideas need to be emphasized which may be followed by rigorous mathematical proofs when students fully understand the intuitive ideas behind the proof.

摘要： 关于游戏和学习之间的关系,向来存在着两个针锋相对的立场。大众舆论对游戏的负面效应口诛笔伐,但新兴的游戏化学习潮流又将游戏奉为学习的真正未来。本文不拟对二者进行仓促的论断,而是首先试图回归哲学史上对于游戏的精神性界定,再由此反思、衡量游戏化学习的利弊得失。游戏化虽然全方位提升了学习的环境和体验,但“重外而轻内”这个根本症结使得它无法真正实现李普曼所追寻的儿童哲学的终极理念,也即引导孩子们对自身的生存意义进行主动积极的探寻。元宇宙的到来似乎实现了这一变革的契机。一方面,它极大地克服了游戏化平台的种种缺陷,进而将哲学化生存和游戏化学习密切地结合在一起,真正敞开了以一种哲学为核心来重构教育的可能途径。但另一方面,元宇宙又并非完美无缺;正相反,升级的监控、人的全面数据化,乃至“媒介被动性”的不平等状态,这些都是摆在未来儿童哲学教育者面前的问题和挑战。

摘要： Female students are underrepresented in Computer Science degree programs at US colleges. This problem has resisted interventions for decades and average enrollment rates are stubbornly hovering around 18%, several success stories at selected institutions notwithstanding. Solutions to this problem require bringing in more female students and once enrolled keeping them in the program. To achieve the latter, improvements have been attempted at the curricular and pedagogical level on one hand, and on the social and community building level on the other. This paper describes a low cost approach to building a sense of community and belonging by making a Women in Computing club more "official" using a "token of belonging." Membership is made more rewarding by the promise of a conference trip

摘要： In this study, we designed, implemented and assessed the integration of cloud computing education and public cloud services into introductory database courses. This is the pilot study for a curricular initiative that integrates cloud computing into core courses across computer science curriculum at a liberal arts college. Direct and indirect evidence show that it is feasible to integrate cloud computing basics into an existing course without impacting students' learning experience and curricular coverage and, given the current billing model, $50 Google cloud credits are enough for four hands-on course activities, but not enough to support students to continue their class projects after class. The paper also discusses cost involved, students' evaluation of Google Cloud Platform (GCP), students' perception of cloud computing, and difficulties encountered and lessons learned in the process.

摘要： Software comprehension is an important part of software maintenance. To understand a piece of large and complex software, the first problem to be solved is where to start the understanding process. Choosing to start the comprehension process from the important software elements has proven to be a practical way. Research on complex networks opens new opportunities for identifying important elements, and many approaches have been proposed. However, the software networks that existing approaches use neglect the multilayer nature of software systems. That is, nodes in the network can have different types of relationships at the same time, and each type of relationship forms a specific layer. Worse still, they mainly focus on identifying important classes, and little work has been done on quantifying package importance. In this paper, we propose an ElementRank approach to provide a ranked list of classes (or packages) for maintainers to start the comprehension process. The top-ranked classes (or packages) can be seen as the starting points for the software comprehension process at the class (or package) level. First, we introduce two kinds of multilayer software networks to describe the topological structure of software at the class level and package level, respectively. Second, we propose a weighted PageRank algorithm to calculate the weighted PageRank value of classes (or packages) in each layer of the corresponding multilayer software network. Then, we use AHP (Analytic Hierarchy Process) to weigh each layer in the corresponding multilayer software network, and further aggregate the weighted PageRank value to obtain the global weighted PageRank value for each class (or package). Finally, all the classes (or packages) are ranked according to their global weighted PageRank values in a descending order, and the top-ranked classes (or packages) can serve as the starting points for the software comprehension process at the class (or package) level. ElementRank is validated
