Collision-free autonomous path planning under a dynamic and uncertainty vineyard environment is the most important issue which needs to be resolved firstly in the process of improving robotic harvesting manipulator intelligence. We present and apply energy optimal and artificial potential field to develop a path planning method for six degree of freedom serial harvesting robot under dynamic uncertain environment. Firstly, the kinematical model of Six-DOF serial manipulator was constructed by using the Denavit-Hartenberg method. The model of obstacles was defined by (...) axis-aligned bounding box, and then the configuration space of harvesting robot was described by combining the obstacles and arm space of robot. Secondly, the harvesting sequence in path planning was computed by energy optimal method, and the anticollision path points were automatically generated based on the artificial potential field and sampling searching method. Finally, to verify and test the proposed path planning algorithm, a virtual test system based on virtual reality was developed. After obtaining the space coordinates of grape picking point and anticollision bounding volume, the path points were drew out by the proposed method. 10 times picking tests for grape anticollision path planning were implemented on the developed simulation system, and the success rate was up to 90%. The results showed that the proposed path planning method can be used to the harvesting robot. (shrink)

This study aims to explore the influence mechanism of COVID-19 risk perception on anxiety in emerging adulthood in the context of public health events of the second round of COVID-19 outbreaks and provide support for exploring the path of mental health after the normalization of the epidemic situation. An online questionnaire, combined with community social work, was used in this study, and data of 522 emerging adults were collected in February 2021. The Perceived Risk of COVID-19 pandemic scale, the generalized (...) anxiety disorder 7-item scale, the scale of affect balance, and the connor-davidson resilience scale were used to investigate. The results showed that: first, the risk perception of COVID-19 in early adulthood was positively predictive of anxiety symptoms [B = 0.110, p < 0.05, 95%CI = ]. Second, the affective quality of life plays a mediating role between the risk perception of COVID-19 and anxiety [B = 0.108, 95%CI = ]. Thirdly, resilience plays a moderating role between the risk perception of COVID-19 and anxiety, the higher the resilience of emerging adulthood, the weaker effects of the risk perception of COVID-19 negative prediction of anxiety [B = −0.110, p < 0.001, 95%CI = ]. Therefore, to control the anxiety of emerging adulthood in public health events, we should pay attention to the propaganda and management of epidemic information, improve the quality of life, and attention should be paid to the emerging adulthood with low resilience.

This study aims to better promote the innovation and entrepreneurship of teachers and students in finance and economics colleges and universities in terms of food security. Based on the relevant theories such as food security, innovation and entrepreneurship, the questionnaire was used to investigate the issues related to food security of teachers and students in colleges and universities. Next, the Technique for Order Preference by Similarity to an Ideal Solution analysis method was introduced to evaluate the safety metrics of the (...) response subsystem. Finally, Internet of Things monitoring technology was applied to grain growth and sales. The research results show that college teachers and students have a disjointed cognition of food security as important talents in innovation and entrepreneurship. After the TOPSIS analysis method is used to study, when college teachers and students choose to start a business in food security, they must pay attention to the changes in economic factors. The IoT monitoring technology is applied to grain growth and sales, and the monitoring technology of the IoT could reduce the mortality rate of corn seedlings to 3.59%. The mortality rate of seedlings is much higher than that of farmers relying on their own experience to grow corn. Therefore, this has great reference significance for the innovation and entrepreneurship development of college teachers and students in food security at this stage. (shrink)

Zou Rong received a classical education but, uninterested in an official career and frustrated by the irrelevance of his schooling to the day's issues, traveled to Japan in 1901 to further his studies. There he wrote The Revolutionary Army, which was published in Shanghai after his return to China in 1903. The Revolutionary Army, which was scathingly critical of the Manchu rulers of China, enraged government authorities who sought his immediate arrest. Zou was protected by authorities of the International Settlement (...) in Shanghai, and eventually sentenced to only two years in jail. Be this as it may, Zou contracted an illness in prison and died in April of 1905. The Revolutionary Army is far more than an anti-Manchu racist tract. It advocates political and social revolution, and Zou's account of the justification for and goals of these revolutions rests in no small part on natural rights and independence, as discussed in the two chapters from the work that we translate here.

Firms use A/B testing, a methodology to compare two or more versions of ideas to see which one performs better, to decide on features of their digital products and services. Although A/B testing brings benefits, some A/B testing can lead to digital exploitation (i.e., appropriating resources from users to increase firms’ performance). We explicate why A/B testing can lead to digital exploitation, suggest mitigation options by establishing Institutional Review Boards, explicitly seeking users’ consent, and implementing incentive schemes, and conclude with (...) research directions on this topic.

Finally, several numerical examples are given (...) to show the effectiveness of our methods. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Crystal Order That Is Most Concrete:The Wittgenstein HouseHui Zou (bio)IntroductionIn the instruction of architectural history, some historical references have to be mentioned in terms of the relationship between building and language. In Chapter I, Book II, of The Ten Books on Architecture, the ancient Roman theorist Vitruvius discussed the "origin of the dwelling house." According to him, the "primitive hut" originated from the gathering of men around a (...) fire through communicating in language.1 In the primitive hut, the origin of architecture was co-presented with the origin of language; the language helped establish a harmonic relationship, which developed builders' construction collectivity. Such a language-collectivity relationship was witnessed in the record of the Tower of Babel in the biblical scripture where the Lord decided to stop the human beings' construction of the tower by "confus[ing] their language there."2 During the Renaissance, the alphabetic language and the design of buildings were correlated through the application of geometry that was supposed to embody the "divine proportion." In the Franciscan professor Luca Pacioli's book On Divine Proportion, letters of the alphabet were geometricized to become objects of contemplation for tracing "God's light."3 In Chinese gardens, there has been a long tradition of naming a specific view with a poetical phrase that thematicized the scene into a meaningful unity of the view and the viewer—jing.4 In all these historical cases, language and building were integrated into a cosmological picture grounded in divine transcendence.After the modernism in architectural history of the 1960s and 1970s, a loss of meaning in architecture was widely observed,5 and the interrelationship between language and architectural design began to emerge as a prominent issue. Several trends in architectural theories during the 1960s and 1970s studied how meaning was created through architectural design. One was the post-modern development in architecture that sought to apply classic architectural elements to the facades of new buildings as gestures to [End Page 22] the past.6 Another trend was phenomenological, which attempted to discover a common language of building contexts that led to building humanized living environments.7 Yet another trend was to apply linguistic approaches to the rational methodology of architectural analysis.8 The analogy of building with language was provoked by an impelling sense of the crisis that the traditional embodied order was being lost in the prevalent instrumentalized practice of architecture.The predicament of the loss of meaning in contemporary architecture can be traced as far back in philosophy as the splitting of mind and body proposed by René Descartes in the seventeenth century. This split began to distance architecture from its traditional embodiment of transcendental meanings in the second half of the eighteenth century9 and finally led to the division of the metaphysical and physical parts in modern architecture, especially after the industrialization of the nineteenth century. Correspondingly, language became an instrumental means for architecture to impose posterior "ideas" to the material bodies of buildings rather than acting as an inherent component of architectural design for the creation of meaning in architecture. The desire for meanings in modern architecture, based on the split of the metaphysical and physical, theoretically catered to linguistic research, such as semiotics, and tended to define architecture as a symbol. The linguistic structure of signifier-signified was, however, coarsely transplanted into architectural theory and reduced architectural symbolism to a simple dualism of idea and form in which the former was usually arbitrarily applied to the latter by a designer. Such an arbitrary imposition of external "meanings" onto an architectural form through language intensified their separation, which in turn produced nihilism in architecture.The lessons learned from the transplantation of linguistic studies into architectural theories remind us that we need to pay close attention to the historical events that could open up the interaction between language and building and reveal the "fundamental linguistic character of our experience of the world" in Gadamer's sense.10 A house designed and built by Austrian philosopher Ludwig Wittgenstein (1889-1951) provides a unique case for us to contemplate this issue. My historical study of the Wittgenstein House is not to understand Wittgenstein's subjective intentions... (shrink)

The Type VI secretion system is a multiprotein and mosaic apparatus that delivers protein effectors into prokaryotic or eukaryotic cells. Recent data on the enteroaggregative Escherichia coli T6SS have provided evidence that the TssA protein is a key component during T6SS biogenesis. The T6SS comprises a trans-envelope complex that docks the baseplate, a cytoplasmic complex that represents the assembly platform for the tail. The T6SS tail is structurally, evolutionarily and functionally similar to the contractile tails of bacteriophages. We have shown (...) that TssA docks to the membrane complex, recruits the baseplate complex and initiates and coordinates the polymerization of the inner tube with that of the sheath. Here, we review these recent findings, discuss the variations within TssA-like proteins, speculate on the role of EAEC TssA in T6SS biogenesis and propose future research perspectives. In the environment, bacteria have to cope with other microbial species and therefore have evolved anti-microbial mechanisms. The bacterial Type VI secretion system transports toxins into bacterial and/or eukaryotic cells using a contractile mechanism. At the architectural level, the T6SS could be viewed as a nano-speargun assembled in the bacterial cytoplasm and anchored to a trans-envelope complex. We describe and speculate on recent findings demonstrating that the TssA subunit is involved in the different stages of T6SS biogenesis. (shrink)

This study via the sensemaking perspective examines whether spiritual leadership can influence employee workplace spirituality and employee corporate social responsibility (CSR) participation. We also examine the joint effects of spiritual leadership and employee Machiavellianism on employee workplace spirituality. Using a sample of 556 employees from four commercial banks in China, analyses demonstrate that employee workplace spirituality mediates the relationship between spiritual leadership and employee CSR participation and that the indirect effect of spiritual leadership on employee CSR participation is dependent on (...) the level of employee Machiavellianism. These results shed light on how and why spiritual leadership and employee Machiavellianism influence employee workplace spirituality and employee CSR participation. The theoretical and practical implications of these finding are discussed along with directions for future research. (shrink)

We explored the division of parenthood in Chinese families with adolescents by identifying the parental involvement patterns in the data obtained from 786 pairs of parents. Division-of-parenthood patterns were created via factor mixture modeling using self-reported three dimensions of father and mother involvement. Three differential division-of-parenthood patterns were identified: (a) parent-cooperation pattern, where moderate and equivalent involvement existed between mothers and fathers; (b) mother-dominated pattern, where mother involvement was particularly greater than father involvement; and (c) father-dominated pattern, where father involvement (...) was particularly greater than mother involvement. Families were more likely to be in the mother- or the father-dominated pattern as their levels of positive coparenting behaviors increased. By contrast, as the levels of paternal conflict behavior increased, families were likely to be in the mother-dominated pattern. This study highlighted parents’ individual parenting role, the diverse division-of-parenthood patterns in the family, and the important role of coparenting behavior. (shrink)

Several recent studies have found that when the other’s gain is greater, even subjects’ reward may seem like a loss and lead to a negative experience. These studies indicate the complexity of reward evaluation in the context of social comparison. The satisfaction rating of reward outcome not only depends on objective social comparison but also on subjective evaluation. However, less is known about the neural time course of subjective evaluation. Therefore, we employed a 2 × 2 within-subjects factorial design, in (...) which we manipulated the reward distribution for the subjects. Electroencephalography responses were recorded, while two subjects concurrently but independently performed a simple dot-estimation task that entailed monetary rewards. Behavioral results showed that the subjects were more satisfied with the advantageous distribution, regardless of upward or downward comparison. The analysis of event-related potentials revealed that disadvantageous distribution elicited a larger P2 than advantageous distribution, and this effect was not modulated by comparison direction. In contrast, the late positive potential showed an effect of comparison direction independent of subjective evaluation. The data suggest that subjective evaluation acts upon the early stage of reward processing and manifests in the P2 component, whereas social comparison plays a role in the later appraisal process.

The outbreak of COVID-19 pandemic has significant social, educational and psychological impacts. While teachers are key agents to promote CT at the curriculum level, little is known about how English language teachers engage with CT in the wake of COVID-19. Drawing on teacher interviews and classroom observations, the study found that the participating teachers navigated the various affordances and constraints of COVID-19 and implemented CT instruction primarily by integrating CT skills in language learning and assessment, emphasizing skepticism, fostering reflection and (...) hope, and legitimating students’ voice in the online environment. It suggests that teachers should be conscious of the affordance and constraints of online teaching and attend to students’ emotions and life experiences at the curriculum time to transform students into critical thinkers who can agentively, responsibly and positively engage with their situated reality.

Despite the role of public health interventions in controlling disease transmission and protecting the public during the COVID-19 emergency, the implementation of quarantine restrictions has raised serious ethical concerns, especially in relation to the well-being of vulnerable populations. Drawing on the lived experiences of rural Chinese migrants who are subject to pandemic control, the authors highlight their inadequate capacities to manage the risks associated with the pandemic and adjust to quarantine restrictions. Informed by an ethical discourse of vulnerability, we show (...) that underpinning this group’s deficient coping strategies is a range of detrimental social structures and institutions that have developed under the persistent rural–urban divide in China. These structural constraints and pathologies expose rural migrants to serious risks and uncertainties while depriving them of the means and resources necessary to protect their own interests in the process of complying with quarantine restrictions. Understanding the plight of rural Chinese migrants as a structural problem also has implications for the global response to the COVID-19 pandemic. We further suggest a need for state intervention to mitigate structural deficiencies and empower the vulnerable during the COVID-19 era. (shrink)

Strong emotional relationships between parents and children are thought to be essential for developing a child's emotion of mattering, according to earlier research. Through the investigation of these relationships, the study aims to improve knowledge of the psychological and emotional elements that support normal growth in the population. To offer regulation for reinforcement of parental support networks in marginalized groups, it draws attention to the importance of these variables in determining the quality of attachment. This study explores the connection among (...) mattering (MAT) and Parental Attachment (PA) with a focus on the dynamics that affect Social Support (SS) and Self Efficacy (SE) between rural Chinese children. Validated questionnaires assessing PA, MAT, SS, SE, and Parental Support (PS) are utilized to collect data from a sample (190) of Chinese children living in rural areas. Significantly favourable connections, especially between MAT and PA, are revealed by correlation analysis. These results reveal avenues for improving the development of rural Chinese children by underlining the significance of social networks and emotional attachments in fostering psychological well-being.

In the traditional Chinese conception, ‘things’ (wu 物) serve as the fundamental ‘components’ of order. Moreover, it is through things and their changes that humans can grasp moral and political norms based on the notion of resonance (ganying 感應). This implies that human society and the world of things are necessarily interconnected. In opposition to this view of order Xiong Bolong 熊伯龍 (1617–1670) in his work Wuhe ji 無何集 (Collected Passages on Being without Causes) critiqued the notion of resonance and (...) arrived at a more ‘disenchanted’ approach to ‘things’ by incorporating the idea of contingency from Wang Chong’s 王充 (27–c. 97) philosophical thought. However, Xiong’s view of order full of contingency does not entirely diverge from the traditional mainstream Chinese view, because in his world of thought, a belief in the underlying necessity of a perfect order within the holistic arrangement of myriad things including humans remained.

This paper examines older people’s access to care experiences in rural China by integrating anthropological investigation with ethical inquiry. Six months of fieldwork in a post-reform primary hospital show how rural residents struggle to access gerontological and nursing care under socially disadvantageous conditions. This anthropological investigation highlights the unmet needs in medical and nursing care for older people, as well as some social, institutional and structural elements that impede access to care. Centring on protecting the vulnerable as informed by feminist (...) ethics scholarship, this paper argues that the failure to meet older people’s dependency needs is unjust, on the premise that it suggests a denial of the inherent value, rights and dignity of older people. This paper appeals for the provision of greater care and support by the state through putting in place social arrangements that better advance older people’s access to care. Some policy recommendations concerning health and social care reform for older people in rural China are also proposed. (shrink)

The Yuanming Yuan of the Qing dynasty was a magnificent imperial garden in Chinese history. The garden consisted of three Chinese gardens and a “Western-like garden” designed by the EuropeanJesuits. The garden encounter in the Yuanming Yuan provides a valuable case for studying cultural fusion in early modernity. This article redraws the traditional line of Daoist cosmology in Chinese imperial gardens by analyzing the fengshui layout of the Yuanming Yuan. Based on the Qing emperors’ writings, imperial archives, and the garden (...) representations, the research interprets the design distinction and its cross-cultural accommodation. The article concludes that the exotic depth produced by the linear-perspective views in the European portion demonstrated the typical Daoist attempt of preserving full brightness in one’s mind through seeking the remotest garden scenery, as stated in the Daoist scripture Laozi that “whoever knows his brightness veils himself in his darkness.” This Daoist paradoxical idea, best embodied by the Yuanming Yuan, opens up a comparative understanding of Heidegger’s concept “paradoxa.”.
