The Philosophical Inspiration of Arendt’s View of Labor on Digital Labor

While introducing Hannah Arendt’s attitude towards labor in her works, Christian Fuchs’ concept of digital labor is introduced, and Arendt’s view of labor is summarized for contemporary labor The critique of the state, the hidden words behind Arendt’s labor thesis, tell people to reflect on the current materialistic and consumer-oriented policy guidance, and to be alert to the hidden danger of laborers who are hidden behind the digital labor under high-tech. At the same time, it expresses as a political philosopher, I have the relentless pursuit of the sublime human nature and the insufficient thoroughness of Marx’s thought of overcoming alienated labor. On the basis of acknowledging Marx’s labor ontology and labor alienation, drawing on Arendt’s labor research results can guide people to pursue a more liberal and ideal world order

The Tianxia System: A Transcendence to the Liberal International Order

The post-World War II Liberal International Order (LIO) promoted democracy, human rights, free trade, and a rules-based system. Yet it has been dominated by powerful countries, leading to limited representation and economic inequality in developing countries. In contrast, the Tianxia system is more inclusive. This study aims to make broader recommendations for addressing the confusion of the international system and the absence of global governance in the context of Sino-US competition. Using the method of comparative analysis, the Tianxia system and LIO are evaluated. The research shows that the Tianxia system surpasses the LIO to varying degrees in theory and practical experience, but it faces implementation challenges. This highlights the difficulty of a single country promoting the establishment of a world system. Therefore, the establishment of the Tianxia system is still incomplete, and more global forces are needed to jointly overcome the crisis of global governance

State Consensus Analysis and Design for High-Order Discrete-Time Linear Multiagent Systems

The paper deals with the state consensus problem of high-order discrete-time linear multiagent systems (DLMASs) with fixed information topologies. We consider three aspects of the consensus analysis and design problem: (1) the convergence criteria of global state consensus, (2) the calculation of the state consensus function, and (3) the determination of the weighted matrix and the feedback gain matrix in the consensus protocol. We solve the consensus problem by proposing a linear transformation to translate it into a partial stability problem. Based on the approach, we obtain necessary and sufficient criteria in terms of Schur stability of matrices and present an analytical expression of the state consensus function. We also propose a design process to determine the feedback gain matrix in the consensus protocol. Finally, we extend the state consensus to the formation control. The results are explained by several numerical examples

The study of middle school teachers' understanding and use of mathematical representation in relation to teachers' zone of proximal development in teaching fractions and algebraic functions

This study examined teachers' learning and understanding of mathematical representation through the Middle School Mathematics Project (MSMP) professional development, investigated teachers' use of mathematics representations in teaching fractions and algebraic functions, and addressed patterns of teachers' changes in learning and using representation corresponding to Teachers' Zone of Proximal Development (TZPD). Using a qualitative research design, data were collected over a 2-year period, from eleven participating 6th and 7th grade mathematics teachers from four school districts in Texas in a research-designed professional development workshop that focused on helping teachers understand and use of mathematical representations. Teachers were given two questionnaires and had lessons videotaped before and after the workshop, a survey before the workshop, and learning and discussion videotapes during the workshop. In addition, ten teachers were interviewed to find out the patterns of their changes in learning and using mathematics representations. The results show that all teachers have levels of TZPD which can move to a higher level with the help of capable others. Teachers' knowledge growth is measurable and follows a sequential order of TZPD. Teachers will make transitions once they grasp the specific content and strategies in mathematics representation. The patterns of teacher change depend on their learning and use of mathematics representations and their beliefs about them. This study advocates teachers using mathematics representations as a tool in making connections between concrete and abstract understanding. Teachers should understand and be able to develop multiple representations to facilitate students' conceptual understanding without relying on any one particular representation. They must focus on the conceptual developmental transformation from one representation to another. They should also understand their students' appropriate development levels in mathematical representations. The findings suggest that TZPD can be used as an approach in professional development to design programs for effecting teacher changes. Professional developers should provide teachers with opportunities to interact with peers and reflect on their teaching. More importantly, teachers' differences in beliefs and backgrounds must be considered when designing professional development. In addition, professional development should focus on roles and strategies of representations, with ongoing and sustained support for teachers as they integrate representation strategies into their daily teaching

Graph-tree-based software control flow checking for COTS processors on pico-satellites

AbstractThis paper proposes a generic high-performance and low-time-overhead software control flow checking solution, graph-tree-based control flow checking (GTCFC) for space-borne commercial-off-the-shelf (COTS) processors. A graph tree data structure with a topology similar to common trees is introduced to transform the control flow graphs of target programs. This together with design of IDs and signatures of its vertices and edges allows for an easy check of legality of actual branching during target program execution. As a result, the algorithm not only is capable of detecting all single and multiple branching errors with low latency and time overheads along with a linear-complexity space overhead, but also remains generic among arbitrary instruction sets and independent of any specific hardware. Tests of the algorithm using a COTS-processor-based on-board computer (OBC) of in-service ZDPS-1A pico-satellite products show that GTCFC can detect over 90% of the randomly injected and all-pattern-covering branching errors for different types of target programs, with performance and overheads consistent with the theoretical analysis; and beats well-established preeminent control flow checking algorithms in these dimensions. Furthermore, it is validated that GTCGC not only can be accommodated in pico-satellites conveniently with still sufficient system margins left, but also has the ability to minimize the risk of control flow errors being undetected in their space missions. Therefore, due to its effectiveness, efficiency, and compatibility, the GTCFC solution is ready for applications on COTS processors on pico-satellites in their real space missions

Fungi: A Neglected Candidate for the Application of Self-Healing Concrete

Self-healing mechanism in concrete has been so far achieved mainly by three approaches: autogenous healing, encapsulation of polymeric material, and biologically induced mineralization of calcium carbonate. The microbial approach prevails over the other two approaches due to the high compatibility between the filler material and the concrete compositions. Although the term “microbe” refers to many different types of organisms, research work on self-healing concrete has been so far restricted to bacteria. In this perspective article, we review the current status of bacteria-mediated self-healing concrete and summarize the prospects for future advances. In particular, we point out that fungi may have distinctive advantages over other microbes to be used as self-healing agents
