Acoustic emission technique is a common approach to identify the damage of the refractories; however, there is a complex problem since there are as many as fifteen involved parameters, which calls for effective data processing and classification algorithms to reduce the level of complexity. In this paper, experiments involving three-point bending tests of refractories were conducted and AE signals were collected. A new data processing method of merging the similar parameters in the description of the damage and reducing the dimension (...) was developed. By means of the principle component analysis for dimension reduction, the fifteen related parameters can be reduced to two parameters. The parameters were the linear combinations of the fifteen original parameters and taken as the indexes for damage classification. Based on the proposed approach, the Gaussian mixture model was integrated with the Bayesian information criterion to group the AE signals into two damage categories, which accounted for 99% of all damage. Electronic microscope scanning of the refractories verified the two types of damage. (shrink)

This study investigated the effect of obstructive sleep apnea on the neural mechanism of visual perception. A preliminary case-control study was conducted. Seventeen patients with moderate to severe OSA in the sleep center of Civil Aviation General Hospital and 20 healthy controls matched for age, sex, and education were recruited. The participants accepted the perceptual contour integration task, compared the differences in behavioral indicators between the two groups, and compared the differences in electroencephalography data between the two groups through event-related (...) potential technology. The groups did not differ significantly in age and gender, but they differed significantly in body mass index. The groups were not statistically different in terms of sleep structure and total sleep time. AHI, sleep efficiency, and minimal SaO2 value in the OSA group were significantly different from those of the control group. The results showed that the average reaction time of the OSA group was significantly longer than that of the healthy control group in the contour integration task. There was no significant difference in the accuracy rate. The results of EEG showed that the amplitudes of N100 of the OSA group were significantly higher than those of the control group at O1, Oz, and O2 electrodes. There was no significant difference in latency between the two groups. At the FCz electrode, the amplitudes of N200 of the OSA group were significantly higher than those of the control group. Therefore, we concluded that in the early stage of the perceptual integration task, although the neural response activity of patients with moderate and severe OSA was not accelerated, they need to call on more psychological resources, activate more neurons in the contour global recognition processing stage, and the compensatory effect of frontal lobe appeared in the stage of visual perception.

This study aimed to investigate how visual–spatial ability predicted academic achievement through arithmetic and reading abilities. Four hundred and ninety-nine Chinese children aged from 10.1 to 11.2 years were recruited and measured visual–spatial, arithmetic, and reading abilities. Their mathematical and Chinese language academic achievements were collected for two consecutive school years, respectively, during the same year as cognitive tests and 1 year after the cognitive tests. Correlation analysis indicated that visual–spatial, arithmetic, and reading abilities and academic achievements were significantly correlated (...) with each other. The structural equation modelling analyses showed that there were two paths from visual–spatial ability to academic achievement: a major path mediated by arithmetic ability and a minor serial mediation path from visual–spatial ability to arithmetic ability to reading ability, then to academic achievement. Results shed light on the importance of visual–spatial ability in education. (shrink)

ABSTRACTThe question of the relation between humans and nature lies at the foundation of any philosophy. With the daily worsening environmental crisis, we are forced to face this ancient question again. Yet when we put it into the form of ‘humans and nature’, a metaphysics is already implied and the problem of nature has not yet been questioned. At this moment, the very question that needs to be put forward is, ‘What is nature’? The question of nature will be interrogated (...) through a comparative view in this essay. First, I argue the modern understanding of nature lies at the root of today’s environmental problems. Then, I go back to early Daoism to explore Daoist thinking on ziran. The meaning of ‘dao emulates ziran’ is brought to light through a detailed interpretation of the ziran of dao and things. Ziran penetrates the dao, the heavenly, the earthly and the human. It is with the understanding of ziran that the nature of humans and all things are illuminated. Heidegger’s... (shrink)

Interpersonal physiological synchrony has been consistently found during collaborative tasks. However, few studies have applied synchrony to predict collaborative learning quality in real classroom. To explore the relationship between interpersonal physiological synchrony and collaborative learning activities, this study collected electrodermal activity and heart rate during naturalistic class sessions and compared the physiological synchrony between independent task and group discussion task. The students were recruited from a renowned university in China. Since each student learn differently and not everyone prefers collaborative learning, (...) participants were sorted into collaboration and independent dyads based on their collaborative behaviors before data analysis. The result showed that, during group discussions, high collaboration pairs produced significantly higher synchrony than low collaboration dyads. Given the equivalent engagement level during independent and collaborative tasks, the difference of physiological synchrony between high and low collaboration dyads was triggered by collaboration quality. Building upon this result, the classification analysis was conducted, indicating that EDA synchrony can identify different levels of collaboration quality. (shrink)

Under the requirements of the national carbon reduction target, the recycling and remanufacturing of scrap iron and steel are taken by major iron and steel enterprises as requirements for implementing industrial carbon emission reduction and are incorporated into their production strategies. The scheduling optimization of scrap iron and steel remanufacturing processes plays an important role in the energy saving and emission reduction of iron and steel enterprises. In this paper, a remanufacturing production decision model for scrap iron and steel considering (...) both the product delivery time and carbon emissions was established, and a discrete krill swarm algorithm was designed to solve the multiobjective production decision model. The effectiveness of the model and the algorithm was verified by an example, demonstrating a good decision-making reference for the implementation of energy conservation and emission reduction in iron and steel enterprises.

The relationship between space (absolute space) and matters (relative space) is similar to that between a stage and performers, where they both exist independently and are interconnected. This work first explores the hypothesis that the Essential space of the Universe is absolute and is zero-dimensional. The second part of the hypothesis discusses that the three-dimensional Universe is a relative space occupied by matters and a representation of its relative positions. The hypothesis in this work will be explored and discussed using (...) reference from the correspondence between Clarke and Leibniz. This work tentatively concludes that the space is absolute and zero-dimensional. (shrink)

As one of the foundations of existential positive psychology, self-transcendence can bring positive intrapersonal and interpersonal outcomes, especially in the COVID-19 era in which people are suffering huge mental stress. Based on Schwartz's theory of human basic values, the current study combines variable-centered and person-centered approaches to examine the relationships between adolescents' values and mental health across two regions in China. The results generally showed that both self-enhancement and conservation values were positively correlated with depression and loneliness, while both self-transcendence (...) and openness to change values negatively correlated with depression and loneliness. The results also showed that there were four value clusters, and, compared to adolescents in the self-focus and undifferentiated values cluster, all adolescents in the anxiety-free values cluster reported lower depression and loneliness, while all adolescents in the other-focus values cluster reported higher depression and loneliness. The differences between the two regional groups only emerged in depression. Specifically, adolescents in Shanghai have higher levels of depression than adolescents in Qingdao. This study provides some evidence for the new science of self-transcendence among adolescents and also sheds light on how we may improve the level of mental health during the COVID-19 era. (shrink)

A tracking control algorithm of nonlinear multiple agents with undirected communication is studied for each multiagent system affected by external interference and input saturation. A control design scheme combining iterative learning and adaptive control is proposed to perform parameter adaptive time-varying adjustment and prove the effectiveness of the control protocol by designing Lyapunov functions. Simulation results show that the high-precision tracking control problem of the nonlinear multiagent system based on adaptive iterative learning control can be well realized even when the (...) input is saturated. Finally, the validity of the proposed algorithm is verified by numerical analysis. (shrink)

With the increasing attention to climate change, air pollution, and related public health issues, China’s new energy vehicles industry has developed rapidly. However, few studies investigated the evolution of interorganizational collaborative innovation networks in the sector domain of NEVs and the influence of different drivers on the establishment of innovation relationships. In this context, this paper uses the joint invention patent of Shenzhen, a low-carbon pilot city of China, to investigate the dynamics of network influencing factors. The social network analysis (...) shows that the scale of coinvention network of NEVs is constantly increasing, which is featured with diversified cooperative entities, and collaboration depth is also expanding. The empirical results from the Exponential Random Graph Model demonstrate that, with the deepening of collaborative innovation, technological upgrading caused by knowledge exchange makes organizations in the network more inclined to cognitive proximity and less dependent on geographical proximity. In addition, organizational proximity and triadic closure contribute positively to the collaborative network, with their relevance remaining nearly the same, while the impeding effect of cultural/language difference is slightly decreasing with time.

Enterprises often post branded content on social media and adopt a proactive response approach to improve digital customer engagement to gain a competitive advantage. However, there are many brands which fail to operate social media as effectively as expected. The effective use of brand social media strategies to improve digital customer engagement remains an ongoing challenge for the enterprises. Based on firm-generated content theory and social presence theory, this study aims to identify the impact of brand social media strategies on (...) different levels of digital customer engagement, including positive filtering, cognitive and affective processing as well as advocacy from content strategy and response strategy. Based on 1,519 brand posts on the official Weibo pages of eight of the top 500 Chinese brands in 2021, this study uses a multiple linear regression model to examine the impact of brand social media strategies on digital customer engagement and the moderating effects of brand image and discretionary purchases. The findings show that, on the one hand, among the brand social media content strategies, action content strategy is associated with higher levels of digital customer engagement. On the other hand, different brand social media response strategies have a differential impact on digital customer engagement levels, with cohesive response being the best strategy for increasing digital customer engagement level. In addition, the effectiveness of brand social media response strategy in digital customer engagement is further moderated by the brand image and discretionary purchases. In contrast, the effectiveness of brand social media response strategy in digital customer engagement is stronger when the brand image emphasizes its “competence” or the discretionary purchases focus on “material purchases.” This study not only enriches the research on digital customer engagement but also provides a reference for the brand strategy selection, design and management based on social media.

The purpose of cause-related marketing (CRM) is to publicise and capitalise on a firm's corporate social performance (CSP) by enhancing its legitimacy in the eyes of its stakeholders. This study focuses on the firm's internal stakeholders - i.e. its employees - and the extent of their involvement in the selection of social campaigns. Whilst the difficulties of managing a firm that has lost or damaged its legitimacy in the eyes of its employees are well known, little is understood about the (...) extent to which managers and their social partners listen to and involve their employees in the legitimation process. Through telephone interviews with non-profit organisations and senior managers of service sector firms, the extent of employee involvement in CRM campaigns and the perceived benefits of doing so are investigated. Amongst other things, we find that (i) the extent of employee participation varies significantly across firms; (ii) larger CRM campaigns tend to be managed centrally with relatively less employee participation than smaller ones and (iii) financial services firms are more likely to make CRM decisions centrally, with relatively less employee participation than retail services firms.

In my dissertation "Kant, Wordsworth, and the Aesthetic Experience," I explore the poetic and political implications of the Kantian aesthetic experience, and use them implicitly for a new reading of Wordsworth's poetry. The dissertation begins by considering Kant's view that beauty and sublimity are what may potentially occur inside each and every one of us in our interaction with any given object rather than what exists outside us in the external world. Emphasizing the reading activity of the spectator rather than (...) the creative endeavor of either divine or secular genius, Kant's depiction of art as a certain subjective and universal experience seems to make possible an analogical discussion of the democratic right and responsibility. Guided by this insight, I examine Wordsworth's similar preference of feeling developed in his poetry over the action and situation, and trace his innovation in both the Lyrical Ballads and The Prelude to instances where the literal text fails to make sense but where that very failure paradoxically produces the possibility of meaning through a certain self-critical inward turn of the narrator/poet/reader outside the narrative. Through the movement from sound , to silence , and to the concurrent possibility of new sound , Wordsworth seems to express his ambivalence toward the conception of poetry as a fixed linguistic construct. Transforming the failure of the literal text into the success of the reading activity, Wordsworth also seems to produce a new kind of reader-oriented poetry which both resembles the French Revolution in its egalitarian aspirations and differs from it in directing its energy not toward any external object but to the moral and cognitive capabilities of the poet himself and his readers. But the ambiguity of sound and silence also tempts Wordsworth at times into championing a certain mythical return to the silence of nature and human infancy, and this self-sacrificial impulse of his poetry and his awareness of it seem to be responsible for the complications and ironies of his creative aspiration and achievement.

This analysis of five factors: the impact of land reform; innovative class system; social control system; the party's primary structure; legalization of words. Analysis of these factors in rural China, "climax" is an organization's success: the organizers are dense, united and effective, is scattered by the organizers, subordination and (...) standstill in space, by pointing to the success of the history of mass mobilization experience and symbolic words, both of which link up well. This paper tries to explain the relative lack of resistance during China's agricultural collectivization campaign, in contrast to the Soviet Union experience in which agricultural collectivization encountered much heavier social resistance. Five factors are analysed: the effects of the Land Reform; the innovative class system; the social control system; th basic-level Party apparatus; the legitimizing discourse. Analyses of these factors reveal that the High Tide in rural China was an organizational success: the organizers were dense, cohesive and efficient, the organized were divided, dependent and spatially paralysed, and the two were well connected through historical experiences and symbolic discourse, all of which point to the success of mass mobilization.

This paper discusses Heller’s aesthetic ethics in her feeling theory. ‘Feeling’ is an aesthetic problem as well as an ethical problem. Heller discusses the important role of emotions in modern life. ‘Housekeeping of feelings’ is the key category of Heller’s ethical aesthetics, which is related to one’s self-realization. It is beneficial to the formation of individual value and helps to reconstruct an increasingly atomized community. The housekeeping of feelings is some kind of care, which is important both ethically and aesthetically. (...) Heller’s feelings theory is based on human value itself, which is of great methodological significance for the reconstruction of the broken emotional community in the post-epidemic era. (shrink)

With the rapid development of the economy, the land use/cover change in the Greater Bay Area has undergone tremendous changes, which have had directly negative effects on ecosystem functions and services. The development of sustainable land use strategies to quantitatively evaluate ecosystem services is required. Based on multitemporal land use data, the equivalent coefficients table method was used to assess the ecosystem service values, and the impact of LUCC on ecosystem services was analyzed. A future land use simulation model and (...) multiscenario simulations were employed to predict land use change in 2030. Our results indicated that the loss of ESVs decreased by 14.29 billion yuan from 2005 to 2020. The spatial distribution of the high-value ecosystem services was concentrated around the peripheral area of the northern regions in the GBA, and those areas had less land use development and human activity. Compared with those in 2020, the total ESVs of the business-as-usual scenario, socioeconomic development scenario, and cultivated protection priority scenario in 2030 decreased, while they increased in the ecological protection priority scenario. In the CPP scenario, regulating, supporting, provisioning, and cultural services increased slightly, but they decreased in the other scenarios. The patterns of LUCC were the main reasons for the decrease in ESVs, such as the loss of land with high ecological value. Additionally, a four-quadrant analysis is introduced to determine which land use simulation will be expected to be adopted by the government. The findings of this study provide valuable information for decision-making and policy development in the coastal zones and for the sustainable management of ecosystems. (shrink)
