BackgroundPsychological resilience may reduce the impact of psychological distress to some extent. We aimed to investigate the mental health status of the public during the outbreak of coronavirus disease 2019 and explore the level and related factors of anxiety and depression.MethodsFrom February 8 to March 9, 2020, 3,180 public completed the Zung’s Self-Rating Anxiety Scale for anxiety, Zung’s Self-Rating Depression Scale for depression, the Connor–Davidson resilience scale for psychological resilience, and the Simplified Coping Style Questionnaire for the attitudes and coping (...) styles.ResultsThe number of people with depressive symptoms was 1,303. The number of people with anxiety symptoms was 1,184. The depressed group and anxiety group had less education, more unmarried and younger age, as well as had significant different in SDS total score, SAS total score, CD-RISC total score, and SCSQ score. The binary logistic regression showed that female, strength, and the subscales of active coping style in SCSQ remained protective factors and passive coping style and higher SAS score were risk factors for depression. Optimism in CD-RISC was a protective factor, and passive coping styles and higher SDS score were risk factors for anxiety.LimitationsThis study adopted a cross-sectional design and used self-report questionnaires.ConclusionThe mental health of the public, especially females, the younger and less educational populations, and unmarried individuals, should be given more attention. Individuals with high level of mental resilience and active coping styles would have lower levels of anxiety and depression during the outbreak of COVID-19. (shrink)

Previous studies revealed that the susceptibility, contacting preference, and recovery probability markedly alter the epidemic outbreak size and threshold. The recovery probability of an infected node is closely related to its obtained resources. How to allocate limited resources to infected neighbors is extremely important for containing the epidemic spreading on complex networks. In this paper, we proposed an epidemic spreading model on complex networks, in which we assume that the node has heterogeneous susceptibility and contacting preference, and susceptible nodes are (...) willing to share their resources to neighbors. Through a developed heterogeneous mean-field theory and a large number of numerical simulations, we find that the recovered nodes provide resources uniformly to their infected neighbor nodes, and the epidemic spreading can be suppressed optimally on homogeneous and heterogeneous networks. Besides, altering the susceptibility and contacting preference does not qualitatively change the results. The susceptibility of the node decreases, which makes the outbreak threshold of epidemic spreading increase, and the outbreak size decreases. Our theory agrees well with the numerical simulations.

This study focuses on user experience from the perspective of big data to complete the aggregation, clustering, and visual presentation of knowledge. Using a combination of sample literature review, visualization technologies, knowledge map analysis, Carrot2 clustering, and other methodologies, this study intends to examine user experience from three perspectives: research state, hotspots, and trends. First, based on the double-map overlay, core institutions, core countries, core authors, core journals, and core references distribution research, the knowledge flow, research power, and research subjects (...) of user experience are analyzed. Secondly, through keyword clustering analysis, this research intuitively presents the research topics of user experience and reveals the research hotspots and the evolution path of research methods. Finally, with the help of the subject clustering algorithm, the emerging trends of user experience research are predicted: the immersive experience upgrade of multi-scenario integration, the innovative design of multi-role collaboration, and the cross-disciplinary interactive exploration of multi-discipline. Following this, the user experience knowledge map is constructed, providing a global view and macro-cognition for subsequent research. (shrink)

Aerial work platform is a kind of engineering vehicle which is used for hoisting personnel to the appointed place for maintenance or installation. Based on the dynamics model considering the flexible deformation existing in the arm system of folding-boom aerial platform vehicle, this study presents a NN-based backstepping controller used for trajectory tracking control of work platform. The proposed controller can reduce tracking error of work platform and suppress the vibration simultaneously by using the RBF neural network system to compensate (...) model uncertainties and disturbances. Furthermore, we prove that the whole system is stable and convergent by Lyapunov stability theorem. In addition, we give the simulation results which show that the good control performance of the designed controller for trajectory tracking and vibration inhabiting of work platform in the case of model uncertainties.

Friedrich Nietzsche has emerged as one of the most important and influential modern philosophers. For several decades, the book series Monographien und Texte zur Nietzsche-Forschung (MTNF) has set the agenda in a rapidly growing and changing field of Nietzsche scholarship. The scope of the series is interdisciplinary and international in orientation reflects the entire spectrum of research on Nietzsche, from philosophy to literary studies and political theory. The series publishes monographs and edited volumes that undergo a strict peer-review process. The (...) book series is led by an international team of editors, whose work represents the full range of current Nietzsche scholarship. (shrink)

Mencius, who often spoke of ming in different senses among which only one can be taken as fate, upheld two doctrines of fate--moral determinism and blind, unalterable fate--but he was prone to apply the former to collective entities, and the latter to individual persons. This bi-level distinction, which is at variance with the non-distinction in both Moism and Taoism, exercised a profound influence upon the minds of later Confucians.

In Philosophical Investigations §244, Wittgenstein suggests that we understand avowals (first-person psychological utterances) as manifestations or expressions of the speaker's mental states. An interesting philosophical theory, called expressivism, then develops from this Wittgensteinian idea. However, neo-expressivists disagree with simple expressivists on whether avowals are at the same time assertions, which are truth-evaluable. In this paper, I pursue the expressivist debate about whether avowals must also be viewed as assertions. I consider and reject three neo-expressivist objections against simple expressivism. Then, I (...) offer my own account of why we should understand avowals as assertions. (shrink)

Epicurus famously argued that death cannot be bad for a person because only painful experiences or something that brings about them can be bad for people, but when a person dies, she cannot experience anything at all, let alone pain. If, as Epicurus argued, death is not something bad for us, then presumably, we have no reason to fear it. In contrast with Epicurus, however, contemporary philosophers of death generally subscribe to the deprivation account of the badness of death, which (...) allows that death can be comparatively bad for the one who dies. Still, many deprivation theorists believe that death, as merely comparatively bad, is not a fitting object of fear. Some of them argue that our attitudes would be unfitting if they respond to comparative value; while others contend that fear is not the kind of attitude that tracks comparative value. In this paper, I critically assess these arguments by deprivation theorists, and argue that, contrary to what these theorists claim, their arguments do not entail that death does not merit fear.

This study presents a semantic analysis of how emotions and emotional experiences are described in Chinese. It focuses on conventionalized expressions in Chinese, namely compounds and idioms, which contain body-part terms. The body-part terms are divided into two classes: those denoting external body parts and those denoting internal body parts or organs. It is found that, with a few exceptions, the expressions involving external body parts are originally metonymic, describing emotions in terms of their externally observable bodily events and processes. (...) However, once conventionalized, these expressions are also used metaphorically regardless of emotional symptoms or gestures. The expressions involving internal organs evoke imaginary bodily images that are primarily metaphorical. It is found that the metaphors, though imaginary in nature, are not really all arbitrary. They seem to have a bodily or psychological basis, although they are inevitably influenced by cultural models. (shrink)

In Authority and Estrangement, Richard Moran provides a fascinating account of how we know what we believe that he calls the “transparency account.” This account relies on the transparency relation between the question of whether we believe that p and the question of whether p is true. That is, we can consider the former by considering the grounds for the latter. But Moran’s account has been criticized by David Finkelstein, who argues that it fails to explain how we know our (...) attitudes and emotions more generally. The aim of this paper is to show how Moran’s transparency account can be extended to meet this criticism by modifying it, using insights from Davidson’s view on attitudes and emotions. (shrink)

With the rapid development of sports science, human motion recognition technology, as a new biometric recognition technology, has many advantages, such as noncontact target, long recognition distance, secret recognition process, and so on. Traditional human motion recognition technology is affected by environmental factors such as motion background, which is prone to rough edges of the recognized objects and loss of motion tracking information, thus further reducing the recognition accuracy. In this paper, the traditional snake model will be improved and optimized (...) to improve the defect of human motion model contour extraction, so as to realize the accurate repair of image contour; in terms of algorithm running time, this paper innovatively improves the construction process of the snake model, further improves the running time of model evaluation, and solves the concave contour problem of corresponding moving objects in the snake model. In order to solve the problem of accurate convergence, this paper improves the snake model of the average moving algorithm and sets the corresponding weight coefficient to distinguish the corresponding moving target background, so as to achieve the convergence of the differential concave contour. In order to verify the superiority of the improved optimized snake model, experiments are carried out in the corresponding database. The experimental results show that the contour of the moving object extracted by the improved snake model algorithm is complete and the segmentation effect is obvious. At the same time, the running speed of the whole algorithm has been significantly improved. (shrink)

Given that there is no recent research on decomposition for global inequality, the aim of this study is to fill the gap in the literature by investigating global inequality with decomposition technique. The data of this study were compiled from the World Bank and decomposition by subgroups was conducted to evaluate the driving forces behind the evolution of inequality. Almost all the countries in the world were included in this study, and the study period spans from 2000 to 2017. The (...) analysis was carried out in several stages to evaluate the issue of North–South divide, as well as the impacts of regional and income subgroups. There are several salient findings derived from this study. First, the results show that there was a gradual decline of international inequality within the study period. Second, there was still a large disparity between the developed and developing countries, and the inequality within the developing countries has aggravated further. Third, geographical location has exerted great impacts on global inequality and East Asia contributed about 40% to the overall decline in international inequality. Fourth, decline in inequality amongst the upper-middle-income countries also contributed substantially to the fall in international inequality. The results derived from this paper can provide pertinent information for the formulation of a comprehensive and coherent strategy in coordinating international efforts and managing inequality while promoting human development under the framework of the newly established Sustainable Development Goals.

ObjectivesIn this study, the effect of WeChat use on the subjective health of older adults was examined.MethodsUsing 2018 China Health and Retirement Longitudinal Study survey data, we attempted to rule out potential endogeneity bias by employing instrumental variable regression to estimate the effects of WeChat use on the health of older individuals. Mobile phone price was chosen as the instrumental variable, and the health of older adults was measured from two aspects: self-rated health and the Center for Epidemiological Studies of (...) Depression Scale.ResultsWeChat use has a significant positive impact on the subjective health of older adults and can significantly improve their self-rated health and mental health status. WeChat use has significant positive effects on the subjective health of both older men and women, but relatively younger older adults obtain more health benefits from WeChat use.ConclusionThe virtual social participation prompted by WeChat use affects the health of older adults. This finding provides a reference for promoting the active integration of older adults into digital life. (shrink)

Emotion recognition plays an important part in human-computer interaction. Currently, the main challenge in electroencephalogram -based emotion recognition is the non-stationarity of EEG signals, which causes performance of the trained model decreasing over time. In this paper, we propose a two-level domain adaptation neural network to construct a transfer model for EEG-based emotion recognition. Specifically, deep features from the topological graph, which preserve topological information from EEG signals, are extracted using a deep neural network. These features are then passed through (...) TDANN for two-level domain confusion. The first level uses the maximum mean discrepancy to reduce the distribution discrepancy of deep features between source domain and target domain, and the second uses the domain adversarial neural network to force the deep features closer to their corresponding class centers. We evaluated the domain-transfer performance of the model on both our self-built data set and the public data set SEED. In the cross-day transfer experiment, the ability to accurately discriminate joy from other emotions was high: sadness, anger, and fear on the self-built data set. The accuracy reached 74.93% on the SEED data set. In the cross-subject transfer experiment, the ability to accurately discriminate joy from other emotions was equally high: sadness, anger, and fear on the self-built data set. The average accuracy reached 87.9% on the SEED data set, which was higher than WGAN-DA. The experimental results demonstrate that the proposed TDANN can effectively handle the domain transfer problem in EEG-based emotion recognition. (shrink)

In this paper, we propose an empirically based Monte Carlo bus-network model as a test bed to simulate intervention strategies to overcome the inefficiencies of bus bunching. The EMB model is an agent-based model which utilizes the positional and temporal data of the buses obtained from the Global Positioning System to constitute a set of empirical velocity distributions of the buses and a set of exponential distributions of interarrival time of passengers at the bus stops. Monte Carlo sampling is then (...) performed on these two derived probability distributions to yield the stochastic dynamics of both the buses’ motion and passengers’ arrival. Our EMB model is generic and can be applied to any real-world bus network system. In particular, we have validated the model against the Nanyang Technological University’s Shuttle Bus System by demonstrating its accuracy in capturing the bunching dynamics of the shuttle buses. Furthermore, we have analyzed the efficacy of three intervention strategies: holding, no-boarding, and centralized-pulsing, against bus bunching by incorporating the rule set of these strategies into the model. Under the scenario where the buses have the same velocity, we found that all three strategies improve both the waiting and travelling times of the commuters. However, when the buses have different velocities, only the centralized-pulsing scheme consistently outperforms the control scenario where the buses periodically bunch together. (shrink)

Since 2016, drones have been deployed in various development projects in sub-Saharan Africa, where trials, tests, and studies have been rolled out in countries, including Tanzania, Uganda, Rwanda, Malawi, Ghana, and the Democratic Republic of the Congo. The use cases of drones vary, ranging from imagery collection to transportation of vaccines, lab samples, blood products, and other medical supplies. A wide range of stakeholders is involved, including governments, international organizations, educational institutions, as well as industry. Based on a field study (...) conducted in 2019, this article investigates how drones are used for medical supply delivery in Malawi-a country where the community is underserved for healthcare and related infrastructure underdeveloped, while airspace is largely open and regulations generally relaxed. The objective of presenting this case study is to contribute to the evidence regarding the rapid deployment of medical cargo drones across the African continent, and to spark critical reflections over the utility, suitability, and impacts of incorporating drones in the existing health supply chain systems in resource-poor settings. The discussion revolves around two aspects: 1) the emergent “African Drone Rise”-is it ok “as it is Africa”? and 2) the normative role of technology in the aid sector-is it “a solution looking for a problem”? In conclusion, a call for more structured guidance for the systematic examination and evaluation of the medical cargo drone case is raised. (shrink)

With the rise of the “humanitarian drone” in recent years, drones have become one of the most controversial public interest technologies that have gained increasing media attention. It is worth noting that, although there is a perception in the aid sector that drones hold the promise to reinvent the health supply logistics, to date, routine drone delivery is still relatively new and largely unproven. This paper presents a recent field study conducted in 2019, where drones were deployed in Malawi to (...) help address the last mile challenge in medical supply delivery, and where a noticeable mentality of “killing two birds with one stone” around the attempt of using drones in resource-poor settings is observed. The objective of the paper is to shed light, through a real-world case study and from the ethical perspective, on the impacts of implementing such a systemic change in the existing health supply chain systems. As conclusion, a call for more reflexive approaches for the critical examination, as well as more structured guidance for the responsible evaluation, of medical cargo drones is raised. (shrink)

Increasingly, humanitarian organizations across the globe have been implementing innovative technologies in their practice as they respond to the needs of communities affected by conflicts, disasters, and public health emergencies. However, technological innovation may intersect with moral values, norms, and commitments, and may challenge humanitarian imperatives. Through the examination of an empirical case study on drone mapping, this paper aims to explore three questions: (1) What are the dynamics between aid delivery and technological innovation in the humanitarian enterprise? (2) How (...) are structural problems addressed in an environment in which technology is being portrayed as a force for change? (3) What moral responsibilities towards vulnerable populations should humanitarian stakeholders bear when introducing innovative technologies in humanitarian action. Discussion revolves around the ideology of “technological utopia”, and the normative role of technology in the aid sector - to make substantive impacts, or to produce “success stories”. In conclusion, a call for rigorous ethical analysis to help foster value sensitive humanitarian innovation (VSHI) is made. (shrink)

A stock divestment campaign is a common strategy used by social activists to pressure corporations to abandon undesirable practices. However, evidence on the effectiveness of the strategy remains mixed. In this paper, we examine the effectiveness of an international stock boycott by studying a large sample of institutional investor transactions in four emerging market stocks targeted by the Sudan divestment campaign from 2001 to 2012. We find evidence of a negative relationship between the intensity of the campaign and the ownership (...) breadth of the stocks, suggesting the effectiveness of the campaign in encouraging investors to divest from targeted companies. Additional analysis indicates that investors in countries that are sympathetic towards CSR activities are more responsive to the divestment campaign. Further, we find evidence consistent with higher campaign intensity being associated with more depressed stock prices. Finally, when performing qualitative content analyses of the annual reports and CSR reports, we find evidence about the effects of the campaign on the targeted companies’ corporate policies and activities in Sudan. In sum, our results support the effectiveness of the stock boycott. (shrink)
