Rapid and precise air operation mission planning is a key technology in unmanned aerial vehicles autonomous combat in battles. In this paper, an end-to-end UAV intelligent mission planning method based on deep reinforcement learning is proposed to solve the shortcomings of the traditional intelligent optimization algorithm, such as relying on simple, static, low-dimensional scenarios, and poor scalability. Specifically, the suppression of enemy air defense mission planning is described as a sequential decision-making problem and formalized as a Markov decision process. Then, (...) the SEAD intelligent planning model based on the proximal policy optimization algorithm is established and a general intelligent planning architecture is proposed. Furthermore, three policy training tricks, i.e., domain randomization, maximizing policy entropy, and underlying network parameter sharing, are introduced to improve the learning performance and generalizability of PPO. Experiments results show that the model in this work is efficient and stable, and can be adapted to the unknown continuous high-dimensional environment. It can be concluded that the UAV intelligent mission planning model based on DRL has powerful intelligent planning performance, and provides a new idea for researching UAV autonomy. (shrink)

For synchronization of a class of chaotic systems in the presence of nonvanishing uncertainties, a novel time-varying gain observer-based sliding mode control is proposed. First, a novel time-varying gain disturbance observer is developed to estimate the uncertainties. Then, by using the output of TVGDO to modify sliding mode control, a new TVGDO-based SMC scheme is developed. Although the observation and control precision of conventional fixed gain disturbance observer-based control for chaotic systems can be guaranteed by a high observer gain, the (...) undesirable spike problem may be caused by the high gain if the initial values of estimate and true states are not equal. The most attractive feature of this work is that the newly proposed TVGDO can eliminate the spike problem by developing a time-varying gain scheme. Finally, the effectiveness of the proposed method is demonstrated by the numerical simulation. (shrink)

Chinese philosophy of religion is a less discussed and less clearly formed area in the study of Chinese philosophy. It is true that there is virtually no discussion in Chinese philosophy about rationality or justification of religious beliefs comparable to the discussion of the same issues in Western philosophy of religion. The inquiry about rationality and justification of religious beliefs has shaped Western philosophy of religion. However, the scope of philosophy of religion in the Western context has been widened since (...) Hume and Kant. When the West began to be exposed to non-Western religions, philosophical reflection on non-Western religions is also brought into the scope of philosophy of Religion. We can expect that the concept of religion will become much broader, the scope of philosophy of religion will expand and new issues, especially, issues concerning specific and non-Western religions, will be framed. When we look at philosophy of religion in a broad sense, the field of Chinese philosophy of religion begins to emerge. In this survey paper, I will focus on several issues which, in a broad sense of philosophy of religion, can be construed as the issues of Chinese philosophy of religion. One of the issues is about the religiosity of Confucianism. The second issue is about the concept of Tian. The third is the issue regarding the origin and nature of Chinese state religion and its characteristics which also have caught the attention of scholars, especially, in China. Is Confucianism a religion? How should we construe the religiosity of Confucianism if it does have a religious dimension? Is Tian a theological term? How does Tian differ from Western God? Is the sacrifice to Tian religious and a form of monotheism? What is the nature of state religion in traditional China? What is the relation between the state religion and Confucianism in traditional China? The debates on the issues addressing these questions will be introduced and discussed in this paper. (shrink)

This study explored the correlation between mental toughness and physical activity, and the moderation role between PA intention and subsequent behavior among college students and wage earners. Five hundred ninety-one college students aged from 19 to 24 and 285 wage earners aged from 27 to 58 recruited from seven colleges and five cities in China. A Theory of Planned Behavior questionnaire, MT Inventory, and the International PA Questionnaire was completed online. Results showed that attitudes, subjective norms, and perceived behavioral control (...) explained 46.5 and 38.3% variance in PA intention among college students and wage earners separately. Intention predicted PA behavior significantly among college students and wage earners. Structural equation modeling indicated that the TPB model and the moderation model have an adequate to good fit except the TPB model among wage earners. MT was positively correlated with PA among college students and wage earners and had a significant moderation role in intention-behavior gap among college students and partially affected the transfer of PA intention to behavior among college students. Individuals with high MT had high levels of PA regardless of intention, while PA of those with low MT was low and unstable. Future research should further explore the correlation between intention and PA and the moderation role of MT in different populations using a longitudinal study in order to better understand the correlation between intention and PA, and the transition from intention to PA and better guidance PA intervention to promote PA.

: Things as concrete beings contain the dimension of value. Value achieves a conceptual realization in evaluation and transforms itself into actual being by virtue of practice, which in turn imparts a new significance to value, namely value as a human creation. Therefore, being and value are in an interactive dynamic unity, which constitutes the reality of the world and accordingly provides a ground for metaphysics to go beyond interpretation of the world to changing the world.

Studies have shown that internal whistleblowing could be utilized as an effective way to stop an organization’s unethical behaviors. This study investigates the relationship between ethical leadership and internal whistleblowing by focusing on the mediating role of employee-perceived organizational politics and the moderating role of moral courage. An analysis of data collected at three phases indicates that employee-perceived organizational politics partly mediates the relationship between ethical leadership and internal whistleblowing. Also, moral courage is found to moderate the effect of employee-perceived (...) organizational politics on internal whistleblowing and the indirect effect of ethical leadership on internal whistleblowing via employee-perceived organizational politics. Theoretical and practical implications of these results are discussed. (shrink)

We show that there exists a properly Σ2 minimal degree b, and moreover that b can be chosen to join with 0′ to 0″ – so that b is a 0″ complement for every degree a such that 0′ ≤ a < 0″.

An incline S is a commutative semiring where r+1=1 for any r \in S . We note that the ideal lattice of an S-semimodule is naturally an S-semimodule and so is its congruence lattice when S is transitive. We prove that the categories of complete S-semimodules, together with dual functor, internal hom and tensor product, is a ⋆-autonomous category. We define the locally and globally maximal congruences which are related to Birkhoff subdirect product decomposition. We show that the categories of (...) S-semimodules, algebraic S-semimodules and topological S-semimodules are equivalent. Finally, we get a sheaf representation of any S-semimodule. (shrink)

For a large proportion of our daily lives, spontaneously occurring thoughts tend to disengage our minds from goal-directed thinking. Previous studies showed that EEG features such as the P3 and alpha oscillations can predict mind-wandering to some extent, but only with accuracies of around 60%. A potential candidate for improving prediction accuracy is the Steady-State Visual Evoked Potential, which is used frequently in single-trial contexts such as brain-computer interfaces as a marker of the direction of attention. In this study, we (...) modified the sustained attention to response task that is usually employed to measure spontaneous thought to incorporate the SSVEP elicited by a 12.5-Hz flicker. We then examined whether the SSVEP could track and allow for the prediction of the stickiness and task-relatedness dimensions of spontaneous thought. Our results show that the SSVEP evoked by flickering words was able to distinguish between more and less sticky thinking but not between whether a participant was on- or off-task. This suggests that the SSVEP is able to track spontaneous thinking when it is strongly disengaged from the task but not off-task thought in general. Future research should determine the exact dimensions of spontaneous thought to which the SSVEP is most sensitive. (shrink)

When the counteroffensive against the February Adverse Current lasted into July and August, things seemed to be looking up for people across the country. Everyone was under the impression that there was hope to "carry the Great Proletarian Cultural Revolution to the end," and that all traditional ideas that fettered people's minds would be cast aside. However, a top-to-bottom adverse current of the counterrevolutionary reformism that that had been around since October suddenly ran rampant; so did an atmosphere of class (...) compromise that suggested: "The first Cultural Revolution is over." People across the country were once again thrown into bewildering confusion, especially the young intellectuals and students who were highly sensitive and the first to feel such changes. So, "What shall we do?'and "Where is China heading?" again became the questions people were asking. The very first reason for establishing the Ultra-Left Commune is to address this serious question.

This paper begins with a discussion of the translations of the term “ontology” in Chinese language, and argues that its translation as “bentilun”(in Chinese PinYinorthography) can be supported by ample evidence from the history of doctrine and the tradition of Chinese culture. Therefore, It is necessary to keep this translation on condition that one distinguish strictly “ontology” as a branch of philosophy from “bentilun” as a special morphology of philosophical theory. Examining the history of metaphysics, this thesis draws a clear (...) line of demarcation between “traditional ontology” and “modern ontology”, and reveals themain characteristics of traditional ontology. It holds that although the reformation of Marx’s Philosophy was realized through criticizing traditional ontology, his Philosophy did not abolish the concept of ontology as a branch of the discipline. The ontology of Marx’s philosophy is a theory that considers natural being, social being and human being as a unity. This theory emphasizes understanding the meaning of being from the perspective of a pattern. The main idea of ontology of Marx’s philosophy is that of a practical outlook and practical model of thinking. First, the concept of ontology and its translations would be reviewed. As regards itsderivation, we could find that Ontologie in German and in French both came from the word of Ontologia in Latin, which originated from the Greek. In the literal meaning of Greek,this word means the “logos” of “on”. In Greek, “on” corresponds to “being” in English. As to its signification, according to Heidegger, “on” has a twofold meaning that can signify both “being in general” and “the ground of being”. The former is close to essence while the latter to origin. From the angle ofhistory, Goclenius was the first one who used the term “Ontologia” in philosophy in 17th century. Since then this word was used and developed by subsequent philosophers. Although this term appeared in 17th century, yet its correlative questions had been studied from ancient Greece. The sticking point here is to pay attention to the demarcation between subject and theory. As a branch subject or as a universal noun, “Ontology” is counted in the historical tradition of western philosophy. Here all the problems discussed are public, but the concrete solutions and viewpoints are different. The former corresponds to the level of subject and the latter to the level of theory. These two levels must not be confused or substituted from one and other. That is, different ideas, schools and opinions could bebrought under the same problem. So it could be said that traditional ontology and modern ontology are two branches. Of course these two branches are very different in dealing with the problem of Ontology. This difference could be illustrated as following: (1) What to be→beings→substance —traditional ontology; (2) How to be→the mode of being→relation—modern ontology. Obviously both begin with the problem of being and end with Ontology, while their approaches are very different. The essential characteristic of traditional ontology is to seek the eternal substance, pursue the transcendent nature, establish the base of knowledge, and take the absolute truth as the ultimate telos. Traditional ontology ended with the critique of modern philosophy, Marxmade the crucial critique of traditional ontology in his remarks on Hegel’s philosophy. His critique of Hegel’s speculative method is actually the critique of traditional ontology although Marx himself never used the term of ontology explicitly in his new philosophy. Being in Marx’s philosophy is the real world of real beings. Concretely speaking, it is sensible world, objective world or human world that is integrated on the base of human praxis. The keystones here are natural being, social being and human being. There are some important similarities between Marx’s ontological approach and Heidegger’s ontology, that is, to understand the meaning of being through the mode and relation of being. In any case, the standpoint and thinking mode of praxis characterize the ontology of Marx’s philosophy. (shrink)

This essay deploys the joint lenses of branding and space to examine the hegemonic operation of the Apple brand in the global culture industry. It does so by analyzing China’s ‘fake Apple Store’ event in 2011, which began with an American expat blogger’s discovery and subsequently caught the attention of global news media. While copying the look of an official Apple Store, these retailers displayed and sold genuine products originally assembled in China. Probing the cultural logic that gave rise to (...) the event, I argue that China’s ‘fake’ Apple Store emblematizes the power relations and subject positions that emanate from Apple’s global hegemony. The Apple Store, as a branded environment, is best seen as a heterotopia whose interpellating mechanism relies on the extensive-intensive character of the intellectual property rights regime. While China’s copycat Apple Store can be seen as an attempt at a production of sameness, the ‘user-generated’ charge of its ‘fakery’ stems from the ‘distributed’ power of the Apple brand, which operates through a production of difference. Even though the varied responses to the event reveal the contradiction within Apple’s extensive global reach, it more importantly points to a condition wherein consumer turned ‘prod-user’ subjects act as self-enlisted agents who work to perpetuate the brand’s design-intensive value regime. While the spectacle of ‘Chinese fakery’ manifests the ideological work of IPR in naturalizing the distinction between the copy and the fake, the extensive-intensive operation of the brand, embodied by the Apple Store, also undermines the ability of consumer subjects to meaningfully engage the ‘Chinese reality’ that is manufacturing labor.

Toni Morrison is widely recognized as an American’s prominent novelist, who magnificently explores the life of the black, especially that of black women. Her Nobel Prize Lecture, in which she again tells a story of a black woman, can be regarded as an epitome of Morrison’s thoughts. The dialogue between the blind black old woman and the young people is full of wisdom and profoundness.
