The aim of this article was to discuss the modeling and control method of quadrotor unmanned aerial vehicle. In the process of modeling, mechanism modeling and experimental testing are combined, especially the motor and propeller are modeled in detail. Through the understanding of the body structure and flight principle of the quadrotor UAV, the Newton–Euler method is used to analyze the dynamics of the quadrotor UAV, and the mathematical model of the UAV is established under the small angle rotation. Process (...) identifier is used to control it. First, the attitude angle of the model is controlled by PID, and based on this, the speed in each direction is controlled by PID. Then, the PID control of the four rotor aircraft with the center of gravity offset is simulated by MATLAB. The results show that the pitch angle and roll angle can be controlled by 5 degrees together without center of gravity deviation, and the PID can effectively control the control quantity and achieve the desired effect in a short time. Classical BP algorithm, classical GA-BP algorithm, and improved GA-BP algorithm were trained, respectively, with a total of 150 sets of training data, training function uses Levenberg-Marquardt, and performance function uses mean squared error. In the background of the same noise, the improved GA-BP algorithm has the highest detection rate, classical GA-BP algorithm is the second, and classical BP algorithm is the worst. The simulation results show that the PID control law can effectively control the attitude angle and speed of the rotor UAV in the case of center of gravity deviation. (shrink)

Prior research on employee–organization relationships has exclusively focused on the positive consequences of high-inducement EORs. Drawing from social exchange theory, we develop a model theorizing employee unethical pro-organizational behavior as one potential negative outcome of high-inducement EORs, as mediated by high-quality social exchange relationship between the employee and the employer. Empirical findings from two field studies provided convergent support to the mediation relationship between mutual-investment EORs and employee UPB via perceived social exchange. Moreover, the results in Study 2 further revealed (...) that the relationship was less significant among employees with higher levels of moral identity, because the positive relationship between perceived social exchange and employee UPB was weakened by high moral identity. The theoretical and managerial implications were discussed. (shrink)

Many moral error theorists reject moral realism on the grounds that moral realism implies the existence of categorical normativity, yet categorical normativity does not exist. Call this the Metaphysical Argument. In response, some moral realists have emphasized a parity between moral normativity and epistemic normativity. They argue that if one kind of normativity is rejected, then both must be rejected. Therefore, one cannot be a moral error theorist without also being an epistemic error theorist. Call this the Parity Argument. In (...) this paper, we address three possible responses to the Parity Argument from moral error theorists: (1) accept the parity but still reject epistemic error theory, (2) reject the parity, (3) accept the parity and defend epistemic error theory. We argue that there are problems with each of these responses, so the Parity Argument stands as a strong counterargument to the Metaphysical Argument. We conclude by drawing some lessons for any future challenges to the Parity Argument. (shrink)

Consumption is one of the important components in the social reproduction circle, which also includes production, distribution, and exchange. Consumer activities should be examined in the social context as well as in the context of the production process. Especially important are impacts of social ethics and individual morality on consumer activities. This paper describes a dialectical relation between ethical and economic evaluations of consumption, presents evidence on Chinese attitudes to borrowing, and proposes a reasonable proportionality between consumption and frugality as (...) a general guideline for consumer activities in contemporary China.

Generally believed that "theory of continuing revolution under the dictatorship of the proletariat" is a "Cultural Revolution" guiding ideology, which in ten years the "Cultural Revolution" period has been widely publicized, has written to the Chinese Communists "nine", "Top Ten", "Eleventh large "by the political report and constitution, but also to write the fourth and fifth National People's Congress meeting adopted constitutional changes, the impact is huge. When it was proposed that "the history of Marxism has set a third great (...) milestone," and after more than ten years later, "since the founding of the party on a number of resolutions on the question of history" has made ​​it a completely different assessment that It is the "leftist" errors and this should be "resolutely corrected." In this paper, the editorial "October Socialist Revolution opened up along the path," CPC "nine", Hua Guofeng, the Third Plenum and "since the founding of the party on a number of resolutions on the question of history," as the coordinates of the tracking the fate of its history and study. q "The Theory on Continuing the Revolution under the Leadership of Proletarians" is commonly regarded as the guiding ideology of the Cultural Revolution. Widely publicized during the decade-long Cultural Revolution, it has been incorporated into the Chinese Communist Party's constitution and the People's Republic of China's constitution for numerous times and has exerted a great influence on the state. By the time it was initially proposed in 1967, it was regarded as' the third landmark in the history of Marxism. But it was subject to a completely different fate more than ten years later as it was labeled "pinko" and was required to he "corrected" in Resolution on Certain Questions in the History of Our Party since the Founding of the People's Republic of China. This paper aims to conduct an investigation of the historical fate of "the Theory on Continuing the Revolution under the Dictatorship of Proletarians" with reference to the following texts: Go Ahead Along the Way Inaugurated by October Socialist Revolution, Report of the Ninth National Congress of the CPC, Hua Guofeng's Talkings, Report of the Third Plenary Session of the 11th Central Committee of the Communist Party of China and Resolution on Certain Questions in the History of Our Party since the Founding of the People's Republic of China.

This article presents a fresh perspective on the interplay among visual, verbal, and auditory modalities, positing that these modalities, as semogenic resources, compete to express dynamic meanings. The theoretical paradigm emphasizes that whether a modality or an element within a modality gets or loses semantic status, it will elicit an additional layer of social meaning to depict a comprehensive picture of a story together with an explicit semiotic meaning. The article adopts a qualitative method to analyze the data, which are (...) drawn from The Good Wife and My Roommate is a Gumiho and annotated in ELAN 6.3. It was found that modal competition can shed light on the dynamic meaning-making processes in semiotic and societal orientations. Modal competition may distort space and time of different stories, and reconstruct a different discursive spatio-temporal dimension in the TV world. It can diversify the dynamic orientations from New to Given in visual, verbal, and auditory texts of multimodal discourses to tell stories. Modal competition provides a lens to understand the multidimensional reality and to appreciate the aesthetics of a modern TV series. (shrink)

An increasingly worrying trend is enterprises undertaking greenwashing rather than producing actual green products. When such greenwashing behaviours are exposed, green brand trust between enterprises and stakeholders may be damaged, resulting in stakeholders becoming suspicious of these supposedly green brands. Then, enterprises need to adopt several trust repair strategies to repair the damaged green brand trust. We investigated green brand trust repair from a green brand legitimacy perspective and found the following: (1) higher green brand legitimacy suggests the use of (...) considered informational, emotional and corrective repair strategies. (2) Meanwhile, lower green brand legitimacy requires the use of timely informational, emotional and corrective repair strategies. Using the correct set of repair strategies may provide practical and effective approaches for enterprises to repair their brand trust. (shrink)

Curiosity and creativity are expressions of the trade-off between leveraging that with which we are familiar or seeking out novelty. Through the computational lens of reinforcement learning, we describe how formulating the value of information seeking and generation via their complementary effects on planning horizons formally captures a range of solutions to striking this balance.

Resumo: A música tradicional chinesa tem uma longa história, repleta de conceitos estéticos ricos e extensos. A integração da música tradicional e das ideias estéticas tem um impacto significativo na formação do sistema musical tradicional da China. Este artigo explora a influência interativa da música tradicional e das ideias estéticas, analisando as ideias musicais da estética tradicional chinesa, buscando promover a integração e o desenvolvimento da música tradicional e das ideias estéticas. Discute o conteúdo das ideias estéticas musicais do confucionismo, (...) taoísmo e moísmo, bem como a posição das ideias estéticas na música tradicional chinesa. Ao combinar e analisar a literatura relevante, livros antigos e materiais históricos, é possível compreender a evolução histórica e a influência mútua da música tradicional e do pensamento estético. Os conceitos estéticos tradicionais não só desempenharam um papel importante no desenvolvimento da música chinesa, mas também na promoção do desenvolvimento da música chinesa, ao longo de milhares de anos de história. Na avaliação da interação entre a música tradicional e o pensamento estético, pode ocorrer uma situação em que o conceito seja demasiado simplificado. A relação entre a música tradicional e o pensamento estético é muito complicada, envolvendo muitas escolas, períodos históricos e regiões. Pode não ser capaz de cobrir totalmente todos os fatores de influência, se for resumido apenas pelo confucionismo, taoísmo e budismo. Sugere-se que a educação e a herança da música tradicional e das ideias estéticas sejam fortalecidas, na educação musical. Artistas musicais mais tradicionais e os teóricos da estética devem ser cultivados, a fim de poder transmitir a música tradicional e as ideias estéticas às gerações futuras e continuar a desenvolver-se e a inovar, na sociedade contemporânea.

Although Canadian consumer magazine advertising still portrayed men more favourably in 1990, its portrayal of women was more positive than before. Advertising faces the dilemma as both a selling tool and a means of social communication. Advertisers have a social responsibility as corporate citizens in ensuring that advertising reflects the continuing improvement of women 's socioeconomic status and power.

This article provides a comprehensive conceptual analysis of information. It begins with a folk notion that information is a tripartite phenomenon: information is something carried by signals about something for some use. This suggests that information has three main aspects: structural, referential, and normative. I analyze the individually necessary and jointly sufficient conditions for defining these aspects of information and consider formal theories relating to each aspect as well. The analysis reveals that structural, referential, and normative aspects of information are (...) hierarchically nested and that the normative depends on the referential, which in turn depends on the structural.

The Cultural Revolution currently underway is just the first one. Many more are sure to follow in the future. In recent years, Chairman Mao1 has often observed that it will take a very long time for history to settle who will be the winner and loser of the revolution. If things go wrong, capitalist restoration is possible at any time. The whole nation and the whole Party must not fall under the impression that everything will be fine after the first, (...) second, third, and fourth Cultural Revolutions. Be sure to keep this in mind; you should never let down your guard. (shrink)

A grafted frame is a new kind of frame which combines a modal frame and some relevance frames. A grafted model consists of a grafted frame and a truth-value assignment. In this paper, the grafted frame and the grafted model are constructed and used to show the completeness of S1. The implications of S1-completeness are discussed. A grafted frame does not combine two kinds of frames simply by putting relations defined in the components together. That is, the resulting grafted frame (...) is not in the form of $\langle W, R, R'\rangle$, or more generally, in the form of $\langle W, R, R', R'',...\rangle$, which consists of a non-empty set with several relations defined on it. Rather, it resembles the construction of fibering proposed by D. M. Gabbay and M. Finger. On a grafted frame, some modal worlds, which belong to the initial modal frame, are attached by some relevance frames. However, these two semantics have important differences. Consider the combined semantics involving semantics of relevance logic and modal logic. A fibred model and a grafted model proposed in this paper differ in the following respects. First, a fibred model is constructed from a class of modal models and a class of relevance models. A grafted model consists of a grafted frame and a truth-value assignment, where the grafted frame is constructed from a modal frame and some relevance frames, and the assignment is a union of a modal truth-value assignment V$_M$ and some relevance truth-value assignments V$_R$. V$_M$ defined in this paper is not the same as the assignment contained in a modal model. Second, in a fibred model each relevance world is associated with a modal model and each modal world with a relevance model. To be the grafted frame on which a grafted model is based, it is enough to have some modal worlds attached by some relevance frames. Moreover, no relevance world is associated with a modal frame in the grafted frame. Third, fibred models are intended to provide an appropriate semantics to combined logics. Grafted frames and grafted models are inspired to characterize S1, which, containing only one modality $\square$, is not a combined logic. It is shown in this paper that S1 is sort of a meta-logic of the intersection of S0.4 and F, where S0.4, a new system proposed in this paper, is in turn a meta-logic of the relevance logic. (shrink)

ObjectiveThe correlation between the performance of coordination movement and brain activity is still not fully understood. The current study aimed to identify activated brain regions and brain network connectivity changes for several coordinated finger movements with different difficulty levels and to correlate the brain hemodynamics and connectivity with kinematic performance.MethodsTwenty-one right-dominant-handed subjects were recruited and asked to complete circular motions of single and bilateral fingers in the same direction and in opposite directions on a plane. Kinematic data including radius and (...) angular velocity at each task and synchronized blood oxygen concentration data using functional near-infrared spectroscopy were recorded covering six brain regions including the prefrontal cortex, motor cortex, and occipital lobes. A general linear model was used to locate activated brain regions, and changes compared with baseline in blood oxygen concentration were used to evaluate the degree of brain region activation. Small-world properties, clustering coefficients, and efficiency were used to measure information interaction in brain activity during the movement.ResultIt was found that the radius error of the dominant hand was significantly lower than that of the non-dominant hand in both clockwise and counterclockwise movements. The fNIRS results confirmed that the contralateral brain region was activated during single finger movement and the dominant motor area was activated in IP movement, while both motor areas were activated simultaneously in AP movement. The Δhbo were weakly correlated with radius errors. Brain information interaction in IP movement was significantly larger than that from AP movement in the brain network in the right prefrontal cortex. Brain activity in the right motor cortex reduces motor performance, while the right prefrontal cortex region promotes it.ConclusionOur results suggest there was a significant correlation between motion performance and brain activation level, as well as between motion deviation and brain functional connectivity. The findings may provide a basis for further exploration of the operation of complex brain networks. (shrink)

Zhou Fohai helped found the Chinese Communist Party but left the party in 1924 and aligned himself with the Guomindang . He then became one of the GMD's leading theoretical writers and was the editor of the monthly Xin shengming. Zhou had earlier contributed to Xin qingnian, and, in an article published in 1922, voiced the opinion that freedom of speech and association should not be given to the bourgeoisie since they then could use these freedoms to thwart (...) the revolution. Although Zhou in 1922 was a supporter of the CCP, and by 1928, when the article excerpted here was published, a theoretician of the GMD, his opinion on the need to restrict certain people's rights and freedoms did not change. Zhou argued against the idea of natural rights because it implied that all people, by virtue of their being human, would enjoy rights. The idea of "revolutionary people's rights" as advocated by the GMD, on the other hand, ensured that only those loyal to the revolution could exercise political rights. (shrink)
