Uninhabited combat air vehicle path planning is a complicated, high-dimension optimization problem. To solve this problem, we present in this article an improved glowworm swarm optimization algorithm based on the particle swarm optimization algorithm, which we call the PGSO algorithm. In PGSO, the mechanism of a glowworm individual was modified via the individual generation mechanism of PSO. Meanwhile, to improve the presented algorithm’s convergence rate and computational accuracy, we reference the idea of parallel hybrid mutation and local search near the (...) global optimal location. To prove the performance of the proposed algorithm, PGSO was compared with 10 other population-based optimization methods. The experiment results show that the proposed approach is more effective in UCAV path planning than most of the other meta-heuristic algorithms. (shrink)
While collaborative curriculum design has gained increasing attention in the field of education, there is scant research as to how EFL teachers implement it in authentic design contexts. The present case study places particular emphasis on teacher activities during collaborative EFL curriculum development in China. The researchers adopt Activity Theory as an analytical tool to understand the relationships between EFL teachers, reform goals, and various aspects of the sociocultural context in which CCD is advocated, highlighting the pivotal role that mediation (...) of knowledge/experience plays in the teacher learning community. Research findings indicate that the TDTs’ collaborative process is a socially constructed and culturally mediated activity that promotes EFL teacher development. Moreover, in-service teachers are prone to take challenges through educational reforms out of teacher motives and external stimuli. Limitations of the CCD model are also discussed to shed light on future research. (shrink)
In _Tang Junyi: Confucian Philosophy and the Challenge of Modernity_, Thomas Fröhlich examines Tang Junyi’s philosophical oeuvre which stands as one of the most ambitious Chinese projects to come to terms with modernity in 20th century.
Performance pressure is a unique stressor in the public sector. Prior studies revealed that it could be a challenge that stimulates functional behavior or a threat that leads to dysfunctional consequences. But these articles failed to provide an integrated theoretical model to explain both phenomena simultaneously. We introduced the double-edged sword effect of performance pressure to fill this theoretical gap. Furthermore, the mediation role of mission valence was examined to explore the buffet mechanism toward this nonlinear relationship. We collected 1,464 (...) valid questionnaire data from snowball sampling to test the research model. Our results revealed that: performance pressure had an inverted U-shaped relationship with dedication and mission valence; performance pressure hurt vigor rather than the curvilinear relationship; mission valence can mediate the inverted U-shaped relationship between performance pressure and dedication. These empirical findings give theoretical contributions and practical insights to public personnel management. (shrink)
In Giddens view, there is historical materialism "reductionism", "evolution" and "functional theory" three defects. "Reductionism," manifested in historical materialism and the complex social relations of human history is about productivity, economic relations and class struggle, etc., as its reconstruction, Giddens proposed to "extend the level of time and space" as the division of social types of new standards; "evolution" of human performance in the history of historical materialism as a lower stage to higher evolving process, as its reconstruction, Giddens made (...) from "pieces" and "time edge" perspective to explain social reproduction and social change as a process of its reconstruction, Giddens proposed a "random social change" model of the new point of view. Giddens reflection of historical materialism and the "reconstruction" has some inspiration, but there are obvious flaws. According to the viewpoint of Anthony Giddens, Historical Materialism ham three main deficiencies: "Reductionism", "Evolutionism" and "Functionalism". "Reductionism" exhibits on the Historical Materialism's reducing the complicated human history and social relationships into the forces of production, economic relationships, class struggles, etc. As an alternation of it, Giddens advances the notion of "level of time-space distanciation", which serves as the new standard for dividing the societal types. "Evolutionism" exhibits on the Historical Materialism's regarding the human history as a process which continuously evolutes from the lower stages to the upper ones. As a reconstruction of it, Giddens brings forward two concepts of "episode" and "time-space edge", which serves as the new criteria for identifying the general outline of the human history. "Functionalism" exhibits on the Historical Materialism's describing the societal reproduction and social change from the viewpoints of "need" and "function". As a revision of it, Giddens puts forward the new model of "contingent social change" . Giddens' endeavors have certain significance in understanding Historical Materialism, but his limitations are also obvious. (shrink)
This study aimed to investigate the common predictive factors between social media addiction and eating disorder symptoms, in a group of Chinese female college students. A total of 216 students completed the behavioral assessments of cognitive flexibility and sustained attention, as well as the questionnaires on anxiety, social media dependence, and eating disorders. The results indicate that SMA is significantly correlated with EDS. Structural equation modeling was used to test the model in which state anxiety, cognitive flexibility, and sustained attention (...) predicted social gain and EDS. Additionally, the results confirmed the mediating role of cognitive flexibility and sustained attention between state anxiety and SMA/EDS in the participants. The findings revealed that in the sample group, state anxiety was related to SMA and EDS through cognitive flexibility and sustained attention. These proposals reflect the significance of improving cognitive flexibility/sustained attention and reducing state anxiety to prevent EDS and SMA in female college students. (shrink)
With self-determination as its implication, freedom can create room for such psychological mechanism as internalization to perform the function of transforming the external social regulation into self-regulation. For this transformation to be viable, however, subject needs to be formed and subsequently social regulation becomes redundant, thanks to the formation of subject. Freedom as a necessary condition for the subject formation and this transfiguration of social regulation is often neglected in favor of social order. Drawing on various intellectual resources, this article (...) explores the inner logic and consequence of Legalism, in its segregation of politics and morality. (shrink)
Tang Junyi (T’ang Chun-i 唐君毅) was among the founders of the Chinese University of Hong Kong, the first chair of the Department of Philosophy at CUHK, an influential scholar of Chinese philosophy, and one of the leaders of the New Confucian movement. In this article, I take issue with the line of interpretation he develops in a provocative 1955 study of Mencius and Mozi. Though I don’t make the connections explicit, Tang’s views and my critique of them are (...) relevant to issues in contemporary discussions of action and motivation, particularly the debate between motivational Humeanism and anti-Humeanism.

We can distinguish two senses of the Given, the nonconceptual and the non-doxastic. The idea of the nonconceptual Given is the target of Sellars’s severe attack on the Myth of the Given, which paves the way for McDowell’s conceptualism, while the idea of the non-doxastic Given is largely neglected. The main target of the present paper is the non-doxastic Given. I first reject the idea of the nonconceptual Given by debunking the false assumption that there is a systematic relation between (...) the conceptual and the nonconceptual. I then propose a constitutive understanding of experience and concept, which at once challenges the idea of the non-doxastic Given. Unlike the more familiar Davidsonian challenge, which questions the transition from the non-doxastic to the doxastic, the constitutive understanding implies that the idea of the non-doxastic Given endangers the very possibility of having thought about the world. I urge an exorcism of the Myth of the Given by proposing doxasticism, the view that experience is essentially a doxastic attitude towards that which is experienced. (shrink)
When stripped to the bare bone, there are only 11 foundational paradigms in social sciences. These foundational paradigms are like flashlights that can be utilized to shed light on different aspects of human society, but each of them can only shed light on a limited area of human society. Different schools in social science result from different but often incomplete combinations of these foundational paradigms. To adequately understand human society and its history, we need to deploy all 11 foundational paradigms, (...) although more limited combinations of them may be adequate for understanding more specific social facts.
