Smart homes represent an effective approach to improve one’s quality of life. Developing user interfaces that are both comfortable and understandable can assist users, particularly the elderly, embrace smart home technologies. It’s critical to concentrate on the characteristics of smart home interface design and their impact on people of various ages. Since sliders are one of the most common components utilized in the smart home user interface, this article aimed to investigate the effects of slider design characteristics on user performance (...) and preference. Thirty-four participants were recruited for the experiment. Our results revealed that both groups had shorter task completion time, less fixation time, and saccades on horizontal sliding orientation and larger buttons, which means better user performance. For the older group, the slider with color gradient track led to better user performance, while the track color only had less effect on the performance of the younger group. In terms of user preference, the results and performance of the older group were basically consistent, while the younger group had no significant difference in sliding orientation and track color.

Objective: To investigate the prevalence of and risk factors associated with mental health symptoms in psychiatric outpatients and their family members in China during the COVID-19 pandemic.Methods: This cross-sectional, survey-based, region-stratified study collected demographic data and mental health measurements for depression, anxiety and acute stress from 269 psychiatric patients and 231 family members in the Second Xiangya Hospital in China from April 27, 2020 to May 8, 2020. Binary logistic regression analysis was performed to identify risk factors associated with mental (...) health outcomes.Result: The results of this survey revealed that symptoms of depression, anxiety, and acute stress were highly prevalent symptoms in the psychiatric patient group. Respondents who were female, unmarried or highly educated were significantly more likely to have the above symptoms. In the family member group, more than half of them felt that the burden of nursing had increased during the epidemic. Subjects with a high degree of burden of care were significantly more likely to exhibit the above mental health symptoms, while females were significantly more likely to have acute stress.Conclusions: The results of this survey revealed a high prevalence of mental health disorder symptoms among psychiatric patients and an increased burden of nursing among their family members after the COVID-19 outbreak in China. Understanding the risk factors in those particular groups of people help improve the public health service system for mental health problems during public health events. For further study, exploration of the needs of mental health services and dynamic change tracking will be needed. (shrink)

First published in 1974. Despite the tendency of contemporary analytic philosophy to put logic and mathematics at a central position, the author argues it failed to appreciate or account for their rich content. Through discussions of such mathematical concepts as number, the continuum, set, proof and mechanical procedure, the author provides an introduction to the philosophy of mathematics and an internal criticism of the then current academic philosophy. The material presented is also an illustration of a new, more general method (...) of approach called substantial factualism which the author asserts allows for the development of a more comprehensive philosophical position by not trivialising or distorting substantial facts of human knowledge.

My wife was a student from among the "workers, peasants, and soldiers" and studied history at university. One day, during her junior year, a female student from a country village announced loudly in class, "I don't know what a eunuch is!" She looked very pleased with herself when she had said this. Other students in the class chimed in: "I don't know either." "Neither do I." My wife is a very straightforward sort of person and she said shyly, "Oh, I (...) think I might know—a eunuch is a man who has been castrated." Someone asked, "What does ‘castrated’ mean?" and she blushed scarlet and was unable to speak. She was only a girl at the time, and it upset her very much to admit in front of everybody that she knew what eunuchs and castration were. For a long while she felt miserable, not daring to see anybody or to say anything. (shrink)

In his book The Road Ahead, Bill Gates writes that modern developments in information technology mean that engineers already have the capability to produce real sensations. They can put goggles on you that show colored pictures and give you stereo earphones so that what you see and hear is controlled by computer. Once the hardware and software are sophisticated enough, we will not be able to tell the difference between electronic sounds and images and real sounds and images. The hardware (...) and software available at present are probably not yet that sophisticated and are not at the stage where this would be feasible; but in the past twenty years technological progress has been amazing, and we must prepare ourselves psychologically for the day when it does become possible.

To this day I still do not know exactly what sort of people are to be regarded as intellectuals, and what sort of people are not. When I was being re-educated in the countryside during the Cultural Revolution, a military representative once told me that I was a "petty bourgeois intellectual." I was only seventeen at the time, had received six years of primary school education, and was barely literate, so I felt I did not deserve to be called an (...) intellectual. By the way, I also felt I did not deserve the appellation "petty bourgeois." My family lived on wages from the government; even our furniture belonged to the government. We had not set up a stall to sell cigarettes in front of our house, so where did he get the term "petty bourgeois"? As for myself as an individual, it was only right and proper that I should belong to one social class or another, and I was not against doing so. However, to this day, I do not know in what class intellectual youths should be counted. In my opinion, if one insists on making comparisons or analogies, they should be counted as lumpen proletarians or the like. But this is taking the subject too far. (shrink)

Someone asks a climber why he wants to climb a mountain—everyone knows that climbing is dangerous and is of no practical advantage—and he replies, "Because it is there." I like this answer because it shows a sense of humor—it is quite clear that it is because he wants to climb it, but he tries to trick us by saying that it is because the mountain is there that he is itching to get at it. Apart from this, I also like (...) what the climber does, scaling sheer cliffs for no good reason. It may cause aching muscles, and there is a risk you might knock your brains out, so the average person does all he can to avoid climbing mountains. From the point of view of thermodynamics, this is the very rarely seen phenomenon of negative entropy. Because human beings always tend toward what is beneficial and avoid what is harmful, and in thermodynamics spontaneous phenomena are known as entropy-increasing phenomena, anything that tends toward the harmful and avoids the beneficial must be negative entropy.

In the history of ethical thoughts of China and the West, ethical relations are always regarded as social relations among people, and the objects to which ethical norms apply are targeted for social business or man’s behavior. What traditional ethics concerns is ethical relationship among people or ethical feature of socialbusiness or man’s behavior. By comparison with it, environmental ethics has a good reputation for its research on ethical relationship between human being and natural environment. It has been discussing and (...) reconstructing ethical relationship between man and nature from the very beginning, and requires ethical solicitude or moral concern for natural environment. As a result, environmental ethics has to answer the question how it is possible. However, the mainstream views in environmental ethics, based on the position of moral expansion and non-anthropocentrism, can't and won't explain how environmental ethics is possible. What environmental ethics deals with is no other than the ethical relationship between man and man represented by the relationship between man and nature, what it confirms is no other than our obligations and duties to others and next generations when dealing with the relationship between man and nature, and finally, the criterion of evaluation it pursues in dealing with the man-nature relationship is no other than the integrated and long-run interest of all human beings. All these are the ground on which the contemporary environmental ethics stands possibly. (shrink)

This paper introduces the history and the present situation of Chinese scholarly research on "Chinese modernity." Due to the limited amount of source materials, this outline is concise and sketchy. Before explaining the tendencies and the characteristics of Chinese scholars' research on modernity, we must first give an overview of the historical sequence of the trends and theories on modernization that were introduced in China from the West and Japan.

Attentional biases have received considerable focus in research on cognitive biases and body dissatisfaction (BD). However, most work has focused on spatial allocation of attention. The current two experiments employed a rapid serial visual presentation (RSVP) task to investigate the temporal allocation of attention to body-related words among young females with high and low BD. Experiment 1 assessed the stimulus-driven attention of body-related stimuli. Participants identified a neutral second target (T2) as accurately as possible while ignoring the preceding neutral, fat-, (...) or thin-related first target (T1). As expected, we observed spontaneous attentional blink effects elicited by fat- and thin-related T1s among participants with high BD, suggesting enhanced awareness of body-related stimuli even when this information does not have to be identified. Such effects did not emerge among participants without BD. Experimental 2 investigated the goal-directed attention of body-related stimuli, during which participants needed to identify both the T1 and neutral T2. Participants with BD showed reduced attentional blink effects after both fat- and thin-related T1, suggesting facilitated consolidation of body-related information in goal-directed attention among participants with BD. The findings may have important clinical implications for understanding how to decrease and even prevent body image dissatisfaction. (shrink)

The essay centers on Gödel's views on the place of our intuitive concept of time in philosophy and in physics. It presents my interpretation of his work on the theory of relativity, his observations on the relationship between Einstein's theory and Kantian philosophy, as well as some of the scattered remarks in his conversations with me in the seventies — namely, those on the philosophies of Leibniz, Hegel and Husserl — as a successor of Kant — in relation to their (...) conceptions of time.

This article has a hermeneutical interpretation of 'heng', one key word in the Laozi. The term 'heng' was not known until 1973 when the two silk manuscripts of the Laozi were unearthed in China. On the base of a reintroduction of heng into the text and of my philosophical reading of the Laozi's concept of 'heng', I argue for an alternative interpretation of dao as heng dao. I suggest that heng dao is neither a metaphysical substance nor mystical nothingness. It (...) is rather the differentiated appropriation of nature and life itself as experienced in the everyday.

Actualist counterpart theory replaces David Lewis’s concrete possible worlds and individuals with ersatz worlds and individuals, but retains counterpart theory about de re modality. While intuitively attractive, this view has been rejected for two main reasons: the problem of indiscernibles and the Humphrey objection. I argue that in insisting that ersatz individuals play the same role as Lewisian individuals, actualists commit the particularist fallacy. The actualist should not require stand-ins for every Lewisian individual. Ersatz individuals should instead be construed as (...) representations of actually existing qualitative ways for individuals to be, or qualitative properties individuals can instantiate. This necessitates changes elsewhere. Non-instrumental uses of Kripke semantics and standard counterpart semantics also require stand-ins for particular non-actual individuals. I argue that the actualist should instead adopt a non-standard counterpart semantics that more clearly illuminates the role that actual properties and relations play in explaining de re possibilities and necessities. The result is an intuitive and forceful reply to both the problem of indiscernibles and the Humphrey objection. (shrink)

According to the reports in the past decade, some Asian subcontractors, mainly Taiwan, Hong Kong and Korea transnational corporations, tend to be labor abusive in their overseas investment destinations like China or Southeast Asia. Taking Vietnam as an example, this paper raises questions as to why Taiwanese transnational companies can control workplace unions in a trade-union-supportive regime. Given the government s constraint of political rights, and the individualized workplace unions, the function of trade unions in Vietnam is destined to be (...) limited. The trade unions turn out be an arm of management, rather than representing workers interests in these transnational companies. This article also explores the influence of the newly developed codes of conducts from Western buyers. In the survey of three companies which are required to follow the codes of conduct by buyers, trade unions had no more freedom than those in companies without codes of conduct. The paper discusses the implications of this research, offering strategies for labor rights improvements. (shrink)

Jean-Paul Sartre argues that human beings are fundamentally incomplete. Self-consciousness brings with it a presence-to-self. Human beings consequently seek two things at the same time: to possess a secure and stable identity, and to preserve the freedom and distance that come with self-consciousness. This is an impossible ideal, since we are always beyond what we are and we never quite reach what we could be. The possibility of completion haunts us and we continue to search for it even when we (...) are convinced it can never be achieved. Sartre suggests that we have to continue seeking this ideal in the practical sphere, even when our philosophical reflection shows it to be an impossibility. Sartre puts this existential dilemma in explicitly theological terms. 'God' represents an ideal synthesis of being and consciousness which remains a self-contradictory goal. This dilemma remains unresolved in his thinking. (shrink)

Coal mine safety management involves many interested parties and there are complex relationships between them. According to game theory, a multiparty evolutionary game model is established to analyze the selection of strategies. Then, a simplified three-party model is taken as an example to carry out detailed analysis and solution. Based on stability theory of dynamics system and phase diagram analysis, this article studies replicator dynamics of the evolutionary model to make an optimization analysis of the behaviors of those interested parties (...) and the adjustment mechanism of safety management policies and decisions. The results show how the charge of supervision of government department and inspection of coal mine enterprise impact the efficiency of safety management and the effect of constraint measures and incentive and other measures in safety management.

This study proposes a research model based on social identity theory, which examines the moderating role of organizational trust on the relationship between corporate citizenship and organizational commitment. In the model, organizational commitment is positively influenced by organizational trust and four dimensions of perceived corporate citizenship, including economic, legal, ethical and discretionary citizenship. The model paths are hypothesized to be moderated by organizational trust. Empirical testing using a survey of personnel from 12 large firms confirms most of our hypothesized effects. (...) Theoretical and managerial implications of our findings are discussed. (shrink)

This paper is concerned with the target tracking problem of an autonomous surface vehicle in the presence of a maneuvering target. The velocity information of target is totally unknown to the follower vehicle, and only the relative distance and angle between the target and follower are obtained. First, a reduced-order extended state observer is used to estimate the unknown relative dynamics due to the unavailable velocity of the target. Based on the reduced-order extended state observer, an antidisturbance guidance law for (...) target tracking is designed. The input-to-state stability of the closed-loop target tracking guidance system is analyzed via cascade theory. Furthermore, the above result is extended to the case that collisions between the target and leader are avoided during tracking, and a collision-free target tracking guidance law is developed. The main feature of the proposed guidance law is twofold. First, the target tracking can be achieved without using the velocity information of the target. Second, collision avoidance can be achieved during target tracking. Simulation results show the effectiveness of the proposed antidisturbance guidance law for tracking a maneuvering target with the arbitrary bounded velocity. (shrink)

Frequent and open interaction between venture capitalists and entrepreneurs is necessary for venture capital investments to occur. Increasingly, these investments are made across jurisdictions. The vast majority of these cross-border investments are carried out in a syndicate of two or more VCs, indicating the effects of intra-industry networks needing further analysis. Using China as a model, we provide a novel multidimensional framework to explain cross-border investments in innovative ventures across developed and emerging economies. By analyzing a unique international dataset, we (...) examine worldwide venture capital investment flows from 2000–2012 and consider the effects of geographical, cultural, and institutional proximity as well as institutional and relational trust. We find trust to mitigate the negative effects of geographical and cultural distance, where institutional trust is more relevant for investments in emerging economies, and relational trust is more relevant for investments in developed economies.

Historical progress is a core belief of the Enlightenment and modernity, also a spiritual catalyst of human emancipation in the past centuries. However, due to the naive understanding of scholars and its misuse by political power, the idea of progress has fallen from a realistic political belief in the pursuit of liberty and democracy to a metaphysical faith and a one-sided ideology. Instead of abandoning the concept itself, this paper will provide a new version for progress. In this version, supported (...) theoretically with ideas from a Marxian critique of the paradox of progress in capitalist society and a Habermasian reconstruction of social evolution and progress, progress shall not be understood as an intrinsic trend of history itself, but a “historical-practical project” of humanity. The intent of rewriting progress is to transcend the dilemma between progressivism and catastrophism while at the same time preserving its positive meaning. (shrink)

For achieving the sustainable development goals, green development has been raised to a high position for cities in China. The economic development in Northwest China is slow, the ecological environment is fragile, and the mineral resources are rich. Only through green development can we realize the comprehensive income of regional production development, rich life, and good ecology. This paper measures the green development efficiency of 30 prefecture-level cities in Northwest China by using DEA-SBM model of unexpected output, explores the differences (...) and causes of green development efficiency from the perspective of time and space through convergence coefficient, coordination matrix, GIS, and other methods, and empirically tests the impact of industrial structure, technological progress, and other driving factors on green development efficiency by using panel Tobit model. The results show that, on the whole, the efficiency of green development in Northwest China is low, path dependence is serious and unbalanced, the coordinated development effect of different regions is weak, and the spillover effect of core urban agglomerations has not been effectively exerted; from the perspective of driving factors, economic development, population density, traffic situation, and education investment can significantly improve the efficiency of urban green development, and the second is that the proportion of industries significantly hinders the improvement of green development efficiency, while the impact of scientific and technological innovation is not significant. Based on the empirical results, this paper believes that the harmonious development of natural environment and economic society can be realized only by improving the coordinated development effect among cities, implementing the optimization and upgrading of industrial structure, introducing excellent talents, and promoting the technological upgrading.

I am working as both a TEFL teacher and an SLA researcher in China, doing SLA research. Recently, I have been working on new approaches to data analysis and I’ve found that a book titled “Data Visualization and Analysis in Second Language Research” by Dr. Guilherme D. Garcia is of great significance in empirical research in the field of SLA. This book serves only as a practical and user-friendly guide to beginners involved in SLA research, but also navigation to veteran (...) SLA researchers devoted to new perspectives in data analysis. So far, the author has made his first attempt to connect data visualization under R to SLA research. The author reviews the previous research results and suggests some modifications through running R. From my perspective, it fills a gap in the SLA research practice—to lead readers into a new track of visualizing their reported results. Overall, to make an increasingly higher demand for SLA research, this book is particularly designated for quantitative data analysis in SLA. It is strongly recommended to write a book review to introduce readers to the realm of data visualization and help most SLA researchers better understand the potential value of R and visualization in SLA research.

Actuator saturation phenomenon often exists in the actual control system, which could destroy the closed-loop performance of the system and even lead to unstable behavior. Our main contribution is to provide an antiwindup recursive dynamic surface control for a discrete-time system with an unknown state and actuator saturation. The fuzzy compensator is added to perform as an active disturbance rejection term in the feedforward path to avoid windup caused by input saturation. To construct output feedback control, the system is transformed (...) into the form of pure-feedback and an improved HOSM observer is designed to carry out future output prediction. Based on which RDSC is synthesized, only one fuzzy logic system is used and the controller singularity is completely avoided. In addition, the simulation and numeral examples using a continuous stirred tank reactors system with actuator saturation are provided and the results show that the strategy owns good robustness and effectively compensates for the disturbance caused by actuator saturation in the presence of a discrete-time system with an unmeasurable state.
