Optimization for vertical vibration performance of a rail-train coupling system is investigated in this paper with the introduction of inerters for both primary and secondary suspensions. A model of a typical Chinese passenger train that travels on a traditional rail with track, sleepers, and ballast is simulated. The goal is to improve the ride quality for the train and vibration attenuation for the rail system in response to track irregularities. Optimizations for only inertance and all suspension parameters are carried out (...) by the particle swarm algorithm. Performance benefits for both the train and the rail system are demonstrated and suspension layouts with inerters connected in parallel and series are compared with the traditional one in both time domain and frequency domain.

BackgroundPublic health guidelines have recommended that elective medical procedures, including deep brain stimulation surgery for Parkinson’s disease, should not be scheduled during the coronavirus pandemic to prevent further virus spread and overload on health care systems. However, delaying DBS surgery for PD may not be in the best interest of individual patients and is not called for in regions where virus spread is under control and inpatient facilities are not overloaded.MethodsWe administered a newly developed phone questionnaire to 20 consecutive patients (...) with PD who received DBS surgery in Ruijin Hospital in Shanghai during the COVID-19 pandemic. The questionnaire was designed to gather the patients’ experiences and perceptions on the impact of COVID-19 on their everyday activities and access to medical care.ResultsMost of the patients felt confident about the preventive measures taken by the government and hospitals, and they have changed their daily living activities accordingly. Moreover, a large majority of patients felt confident obtaining access to regular and COVID-19-related health care services if needed. Routine clinical referral, sense of security in the hospital during the outbreak, and poor control of PD symptoms were the three main reasons given by patients for seeking DBS surgery during the COVID-19 pandemic.ConclusionThe COVID-19 pandemic has considerably impacted medical care and patients’ lives but elective procedures, such as DBS surgery for PD, do not need to be rescheduled when the health care system is not overloaded and adequate public health regulations are in place.

Junzi (君子 gentleman) is the ideal personality for Confucius. To perform benevolence ( ren 仁) and righteousness ( yi 義) is the responsibility of a junzi. A junzi also esteems bravery, which takes benevolence and righteousness and the justification of the enterprise as its prerequisites. A junzi must do things properly and act in accordance with the mean ( zhongyong 中庸). How does one achieve the mean? The person concerned needs to be flexible with the principles and the circumstances of (...) the situation. A person is not born a junzi, but to become one. And to become a junzi, one needs to cultivate one’s character, which includes the cultivation of the inner spirit and the literature and arts. Confucius’ theory of junzi is still relevant in modern times, and modern society needs a new type of junzi. (shrink)

The Mobile Phone Addiction Index is a short instrument to assess mobile phone addiction. The Chinese version of this scale has been widely used in Chinese students and shows promising psychometric characteristics. The present study tested the construct validity and measurement invariance of the MPAI by gender in middle school adolescents. The data were collected from 1,395 high school students. Confirmatory factor analysis and multiple-group CFA for invariance tests were conducted on the MPAI model which consisted of 17 observed items (...) and 4 latent factors. Findings showed that the data fit the four-factor structure model well for both males and females. Furthermore, configural, metric, scalar, and residual invariance were established by gender. The results indicated that the MPAI has acceptable psychometric properties when used in adolescents. In addition, with the strict invariance requirements being satisfied, the underlying factor scores for MPAI can be meaningfully compared across genders. To our knowledge, this study is the first attempt to test the measurement invariance of the MPAI across male and female adolescents. Our results will support future research on mobile phone addiction in adolescents. (shrink)

We examine the link between a firm’s environmental and social disclosures and measures of its risk including total, systematic, and idiosyncratic risk. While we do not find any link between a firm’s E and S disclosures and its systematic risk, we find a negative and significant association between these disclosures and a firm’s total and idiosyncratic risk. These are novel findings and are consistent with the predictions of the stakeholder theory and the resource-based view of the firm suggesting that firms (...) which make extensive and objective E and S disclosures promote corporate transparency that can help them build a positive reputation and trust with their stakeholders. This in turn can help mitigate the firms' idiosyncratic/operational risk. These findings are important for all corporate stakeholders including managers, employees, and suppliers who have a significant economic interest in the survival and success of the firm. (shrink)

This study focuses on mindfulness programs in the corporate world, which are receiving increasing attention from business practitioners and organizational scholars. The workplace mindfulness literature is rapidly evolving, but most studies are oriented toward demonstrating the positive impacts of mindfulness as a state of mind. This study adopts a critical perspective to evaluate workplace mindfulness practice as a developmental process, with a focus on its potential risks that have ethical implications and are currently neglected by both researchers and practitioners. We (...) draw from a Buddhist perspective that understands mindfulness training as an ethics-based, longitudinal, and holistic path. To this end, we develop a four-stage model to illustrate a potential developmental process for participants in workplace mindfulness programs. This model comprises four stages of preliminary concentration, deep concentration, self-transcendence, and reengagement, each of which has its own underlying characteristics and impacts on individual participants and organizations.

Using data from China’s public debt markets, we study the value of corporate reputation and how it interacts with legal and cultural forces to assure accountability. Exploring lawsuits that change corporate reputation, we find that firms involved in lawsuits experience a decrease in bond values and a tightening of borrowing terms. Using the heterogeneities in legal and social capital environments across Chinese provinces, we find the effects are more pronounced for private firms, firms headquartered in provinces with low legal protections, (...) and firms headquartered in provinces with high social capital. The results show that lawsuits that allege misconduct are associated with reputational penalties and that such penalties serve as substitutes for legal protections and as complements to cultural forces to provide ex post accountability and motivate ex ante trust.

In this paper, we present a probabilistic-based method to predict malaria disease at an early stage. Malaria is a very dangerous disease that creates a lot of health problems. Therefore, there is a need for a system that helps us to recognize this disease at early stages through the visual symptoms and from the environmental data. In this paper, we proposed a Bayesian network model to predict the occurrences of malaria disease. The proposed BN model is built on different attributes (...) of the patient’s symptoms and environmental data which are divided into training and testing parts. Our proposed BN model when evaluated on the collected dataset found promising results with an accuracy of 81%. One the other hand, F1 score is also a good evaluation of these probabilistic models because there is a huge variation in class data. The complexity of these models is very high due to the increase of parent nodes in the given influence diagram, and the conditional probability table also becomes more complex. (shrink)

In this paper, we draw on insights from theories in the management and corporate governance literature to develop a theoretical model that makes explicit the links between a firm’s corporate social responsibility related board attributes, its board CSR strategy, and its environmental and social performance. We then test the model using structural equation modeling approach. We find that the greater the CSR orientation of the board, the more proactive and comprehensive the firm’s CSR strategy, and the higher its environmental and (...) social performance. Moreover, we find this link to be endogenous and self-reinforcing, with superior CSR performers tending to further strengthen their board CSR orientation. This result while positive is also suggestive of the widening of the gap between the leads and laggards in CSR. Therefore, the question arises as to how ‘leaders’ are using their superior CSR competencies seen by many scholars as a source of corporate competitive advantage. Stakeholders of corporations therefore need to be cognizant of this aspect of CSR when evaluating a firm’s CSR activities. Policy makers also need to be cognizant of these concerns when designing regulation in this field. (shrink)

Customers are increasingly talking positively about brands that are socially responsible and authentic. However, little empirical research has related corporate social responsibility (CSR) to brand authenticity and brand authenticity to customers’ positive word-of-mouth. Moreover, although highly attractive alternative brands are increasingly appearing in the marketplace, there is a lack of research examining the role of alternative attractiveness in the relationship between CSR and brand authenticity. We address these shortcomings in the literature drawing on data from 1,101 customers of insurance services (...) brands and analyze them using structural equation modeling. The findings show that CSR is positively related to customers’ positive word-of-mouth, both directly and indirectly, through brand authenticity. Moreover, alternative attractiveness positively moderates the effect of CSR on brand authenticity. This implies that CSR can act as a differentiation mechanism to further enhance the focal brand’s authenticity, when an alternative brand is perceived as highly attractive. (shrink)

The application of digital technology in teaching has triggered the evolution of traditional teaching. Students have different corresponding relationships under digital behavior. The interactive technology of artificial intelligence and virtual reality provides a new driving force for the development of art education and psychology. Firstly, this thesis analyzes the limitations and existing problems of traditional art education. Especially, the influence of the teaching mode of art education on the teaching of other disciplines develops a targeted student-centered digital education program. Secondly, (...) the author used VR equipment and technology to let students experience the virtual world freely, and then, the relevant data model was established on the basis of analyzing the reasons affecting students’ creativity and concentration. Thirdly, the data model was applied to art education in order to improve students’ concentration and creativity. Then, the author compared and analyzed the data of the students under different teaching models through questionnaires. The results show that introducing VR and AI technology into art education and encouraging students to carry out deep learning can significantly improve student concentration and creativity. Finally, the influence reasons are analyzed from the perspective of psychology. VR interaction and Artificial Intelligence can be introduced into middle school fine art education which is to the benefit of students’ deep learning, thus students’ concentration and creativity can be improved.

In this chapter, we argue that Du Châtelet’s account of motion is an important contribution to the history of the absolute versus relative motion debate. The arguments we lay out have two main strands. First, we clarify Du Châtelet’s threefold taxonomy of motion, using Musschenbroek as a useful Newtonian foil and showing that the terminological affinity between the two is only apparent. Then, we assess Du Châtelet’s account in light of the conceptual, epistemological, and ontological challenges posed by Newton to (...) any relational theory of motion. What we find is that, although Du Châtelet does not meet all the challenges to their full extent, her account of motion is adequate for the goal of the Principia: determining the true motions in our planetary system.
