To mitigate risk, should companies signal a broad range of environmental, social, and governance initiatives or instead focus on only a few ESG issues? Drawing on signaling theory, we propose that a broad array of ESG initiatives generates not only signal consistency but also accelerating signal costs. Our empirical results support the resultant hypothesis of a curvilinear relationship between ESG scope and equity risk. In addition, this U-shaped curve seems to become steeper when firms face multiple media-reported ESG controversies. Overall, (...) our study qualifies the conventional wisdom that firms can reduce equity risk by attending to a wide variety of stakeholders and highlights the moderating impact of the firm’s media environment.

The purpose of this note is to study impulsive control and synchronization of memristor based chaotic circuits shown by Muthuswamy. We first establish a less conservative sufficient condition for the stability of memristor based chaotic circuits. After that, we discuss the effect of errors on stability. Meanwhile, we also discuss impulsive synchronization of two memristor based chaotic systems. Our results are more general and more applicable than the ones shown by Yang, Li, and Huang. Finally, several numerical examples are given (...) to show the effectiveness of our methods. (shrink)

To better reflect the precise clustering results of the data samples with different shapes and densities for affinity propagation clustering algorithm, an improved integrated clustering learning strategy based on three-stage affinity propagation algorithm with density peak optimization theory was proposed in this paper. DPKT-AP combined the ideology of integrated clustering with the AP algorithm, by introducing the density peak theory and k-means algorithm to carry on the three-stage clustering process. In the first stage, the clustering center point was selected by (...) density peak clustering. Because the clustering center was surrounded by the nearest neighbor point with lower local density and had a relatively large distance from other points with higher density, it could help the k-means algorithm in the second stage avoiding the local optimal situation. In the second stage, the k-means algorithm was used to cluster the data samples to form several relatively small spherical subgroups, and each of subgroups had a local density maximum point, which is called the center point of the subgroup. In the third stage, DPKT-AP used the AP algorithm to merge and cluster the spherical subgroups. Experiments on UCI data sets and synthetic data sets showed that DPKT-AP improved the clustering performance and accuracy for the algorithm. (shrink)

Enhancing teacher leadership is not only one of the approaches to improving teaching and learning, but it is also essential to the success of education reform. Based on leader-member exchange theory, 294 preschool teachers in China were surveyed, and a structural equation model was established to explore the relationship between the participating teachers' principal leadership style, teacher leadership and psychological capital. The findings revealed a significant positive correlation between transformational and transactional leadership styles and preschool teacher leadership. The laissez-faire leadership (...) style had no correlation with preschool teacher leadership. The transformational leadership style and transactional leadership style were significantly and positively correlated with psychological capital, while the laissez-faire leadership style was significantly and negatively correlated with psychological capital. The transformational leadership style can positively influence preschool teacher leadership directly and indirectly through psychological capital; and the transactional leadership style can only positively influence preschool teacher leadership indirectly through the mediating role of psychological capital. Preschool teachers' leadership can neither be directly influenced by a laissez-faire leadership style nor be indirectly influenced through the mediating role of psychological capital. (shrink)

This paper uses the Process Dissociation Procedure to explore whether people can acquire unconscious knowledge in the serial reaction time task [Destrebecqz, A., & Cleeremans, A. . Can sequence learning be implicit? New evidence with the Process Dissociation Procedure. Psychonomic Bulletin & Review, 8, 343–350; Wilkinson, L., & Shanks, D. R. . Intentional control and implicit sequence learning. Journal of Experimental Psychology: Learning, Memory, and Cognition, 30, 354–369]. Experiment 1 showed that people generated legal sequences above baseline levels under exclusion (...) instructions. Reward moved exclusion performance towards baseline, indicating that the extent of motivation in the test phase influenced the expression of unconscious knowledge. Experiments 2 and 3 revealed that even with reward, adding noise to the sequences or shortening training led to above-baseline exclusion performance, suggesting that task difficulty and the amount of training also affected the expression of unconscious knowledge. The results help resolve some current debates about the role of conscious awareness in sequence learning. (shrink)

The challenge from the sophists with whom Plato is confronted is: Who can prove that the just man without power is happy whereas the unjust man with power is not? This challenge concerns the basic issue of politics: the relationship between justice and happiness. Will the unjust man gain the exceptional happiness of the strong by abusing his power and by injustice? The gist of Plato’s reply is to speak not of justice but of intrinsic justice, i.e., the strength of (...) virtue which, in his account, is the fundamental good of man. Nevertheless, many contend that intrinsic justice is actually injustice, for the division of power in the state is undemocratic while in the soul, the suppression of desire by the reason. Plato’s advocacy of hierarchical, elite political system has enraged democrats, while his idea of philosopher king has enraged the aristocrats as well. So, who will appreciate Plato’s effort?

This paper discusses Eastern European Marxists’ consideration of science and technology concerning aesthetic dimensions. Different from most of Western Marxists who take negative or dystopian attitudes towards modern science and technology from the aesthetic utopian perspective, those Marxists who come from countries such as Hungary, Yugoslav, Poland, Czechoslovakia, East Germany, Bulgaria or Romania, which once belonged to the socialist camp, under the influence of Soviet and Western culture, pay attention to the complicated tension between science-technology and aesthetics. In this paper, (...) I probe into these notions by reading György Lukács, Budapest School, Romanian theorists and the Yugoslav Praxis Group, which are divided into four key points: basic nature of science in contrast with arts; modern tension of culture between science and arts; the possibility of scientific aesthetics; and development of arts in the world of technology. There is a dialectical understanding of science and technology here which contributes to contemporary recognition of science and technology from the point of view of neo-humanism, not only in aesthetics but also human existence. This is relevant to theoretical reflection on the present and future Chinese socialist aesthetics. (shrink)

This paper offers a short history of Agnes Heller’s relationship to China through three aspects: imaginative aesthetic enjoyment, real encounters with Chinese cultural spectacles and actual audiences, and the construction of an academic community through creative dialogue. These discussions suggest that Heller felt at home in China. Although Heller has passed away, a home for us remains in her work through remembering her and engaging further with her writings.

The conceptual and methodological contributions of Marxist aesthetics from Eastern European countries like Hungary, Yugoslavia, Poland, Czechoslovakia, Bulgaria, Romania, and East Germany were productive and significant despite various hurdles faced concerning institutionalization, legitimization and differing theoretical abuses. In its mode of inquiry and discursive practices, Eastern European Marxist aesthetics is both similar and dissimilar to its Western, Soviet, Russian and Chinese counterparts. The specificity here is the function of a unique geographical and socio-historical context, as well as interaction with other (...) contemporary paradigms of thought. The innovative impulses of Eastern European Marxist aesthetics affected six scholarly domains: aesthetics of praxis, theory of realism, critique of modernity, semiotics, theory of genre and cultural theory. This paper provides a general survey of the intellectual achievements of Eastern European Marxist aesthetics across these six domains and will show how this theoretical tradition has influenced the modern history of ideas.

Past research suggests that spiritual leadership plays a pivotal role in enhancing employee job performance, yet we have little understanding of how and when spiritual leadership enhances employee job performance. The present study explores how and when spiritual leadership promotes job performance by examining relational energy as a mediator and leader integrity and relational energy differentiation as boundary conditions. We tested the theoretical model with data gathered across three phases over 12 months from 497 employees and their supervisors in 108 (...) groups. Results showed that the positive relationship between spiritual leadership and job performance was mediated by relational energy. Moreover, we found that leader integrity amplified the mediated relationship between spiritual leadership and employee job performance via relational energy. In contrast, relational energy differentiation weakened this mediated relationship. (shrink)

H. L. A Hart complained about the ambiguity of legal positivism, and proposed a definition that refers to particular explications of the concept of law, to certain theories of legal interpretation, to particular views on the moral problem of a duty to obey the law, and to a sceptical position with regard to the meta-ethical issue of the possibility of moral knowledge. It is said to be restricted to the Thesis of Separation — the contention that there is no necessary (...) connection between law and morals. In this chapter, the Separation Thesis is discussed even further, and has three shortcomings identified: first, that it has been vacillating between object-level contentions about moral qualities of the law; that the precise logical relation between both levels has never been properly accounted for; and that the question of necessary relations between morality and law hinges crucially on the presupposition that the very concept of law itself does not unravel into different sets of convenient stipulations from different epistemological angles, each of which renders the question of such necessary relations trivial. The Separation Thesis is also identified as having two versions: the Fallibility Law and the Neutrality Law. (shrink)

ABSTRACT The ongoing Sino-U.S. trade dispute between the world’s two largest economies has since 2018 attracted much attention from the international media. This study used the approach of corpus-assisted discourse studies to compare how leading English-language newspapers from each side—The New York Times and China Daily — discursively constructed this issue. The findings indicated that while NYT tended to profile the trade conflict as a ‘war’ in line with mainstream hard-line ideologies that emphasize China’s presumed threat to national security of (...) the U.S., CD sought to dial down the rhetoric and showed a preference for defining the matter as a ‘friction’, consistent with the tenet of ‘pragmatic nationalism’ endorsed by the Communist Party of China. Accordingly, the two newspapers framed the causes, moral evaluation/consequences, and treatment of the issue in congruence with their respective dominant metaphors by means of various linguistic patterns. These differences are interpreted with regard to each side’s underlying ideologies and national interests. (shrink)

György Márkus, as a leading member of the Budapest School led by György Lukács in Hungary, is closely concerned with aesthetics. His final unfinished writings in political exile in Sydney were focused on the question of modern cultural autonomy. From the 1960s to the new century, from Budapest to Sydney in Australia, he established a new form of Neo-Marxist aesthetics on the basis of critical theory drawn from Lukács to the Frankfurt School. His aesthetics includes three dimensions: an aesthetics of (...) praxis, a reconstruction of Lukács’s aesthetics and a theory of aesthetic modernity. His aesthetics is characteristic of analytic philosophy, especially ‘categorical analysis’. It shifts from philosophical aesthetics in the Hungarian period, which is based on an ontological foundation, that is, materialist phenomenology, to social or sociological aesthetics in the Australian period concerning social modernity, institution, constitution, culture, and so on. This is a turn from a philosophical paradigm to a structural one as regards aesthetics, which indicates a break with Lukács’s late return in the early 1960s to Hegelian inspired Ontology of Social Being. Márkus is strictly and essentially an essayist in fragments, who distinguishes himself from the other members of the Budapest School in this way. Ironically, this genre is once again influenced by the young Lukács’s aesthetics. (shrink)
