This article argues for an anti-deflationist view of scientific representation. Our discussion begins with an analysis of the recent Callender–Cohen deflationary view on scientific representation. We then argue that there are at least two radically different ways in which a thing can be represented: one is purely symbolic, and therefore conventional, and the other is epistemic. The failure to recognize that scientific models are epistemic vehicles rather than symbolic ones has led to the mistaken view that whatever distinguishes scientific models (...) from other representational vehicles must merely be a matter of pragmatics. It is then argued that even though epistemic vehicles also contain conventional elements, they do their job of demonstration in spite of such elements. (shrink)

One might say that the majority of scholars, experts, and professors in the United States are of the bookish type. Most of them are content with immersing themselves in academics in the ivory towers of their academic palaces and prefer to exist in solitude; they seldom seek the limelight in the media, and in general rarely engage in politics. Apart from a very few exceptions at Harvard University and at a number of research institutes, not many people serve as "think (...) tanks" to defend American government policy or give advice and suggestions. American scholars generally regard themselves as liberals, assume some sort of critical attitude toward the American government, the U.S. Congress, and the American media and maintain the lofty, aloof-from-politics-and-worldly-considerations attitude of scholars and specialists—or, as the intellectual elite, maintain a distance from society and actual politics. Of course, the circumstances of scholars who engage in studies closely linked with the actual operations of American society, such as economics, political science, the science of international relations, and the science of international politics, are rather special, and they have more opportunities to go into politics. But when they engage in academic studies, they place great emphasis on the academic and independent nature of their studies. (shrink)

In parallel with the rapid rise in breast cancer incidence, there is also a noticeable rise in the number of patients who experience persistent negative body image cognition after breast cancer surgery. This study aimed to explore the differences in illness perception, social support, and body image cognition among breast cancer patients with different surgical methods, and the correlation, regression, and mediation among the three variables. The Brief Illness Perception Questionnaire, the Social Support Rating Scale and the Body Image Cognition (...) after Breast Cancer Questionnaire were used to evaluate breast cancer patients’ illness perception, social support and body image cognition. Data analyses were performed by descriptive statistics, independent samples t-test, analysis of variance, Pearson correlation, and linear regression. The mediation was explored by the PROCESS V3.3. The study found that breast cancer patients undergoing radical mastectomy and modified radical mastectomy demonstrated more negative illness perception, body image cognition, and lower social support compared with the patients receiving nipple-sparing mastectomy. The subscale cognitive representation of BIPQ was strongly positively correlated with BIBCQ. Illness perception positively predicted body image cognition, while social support negatively predicted body image cognition. Social support partially mediated illness perception and body image cognition, exhibiting a positive role in post-operative body image cognition. (shrink)

Governments and citizens of nearly every nation have been compelled to respond to COVID-19. Many measures have been adopted, including contact tracing and risk assessment algorithms, whereby citizen whereabouts are monitored to trace contact with other infectious individuals in order to generate a risk status via algorithmic evaluation. Based on 38 in-depth interviews, we investigate how people make sense of Health Code, the Chinese contact tracing and risk assessment algorithmic sociotechnical assemblage. We probe how people accept or resist Health Code (...) by examining their ongoing, dynamic, and relational interactions with it. Participants display a rich variety of attitudes toward privacy and surveillance, ranging from fatalism to the possibility of privacy to trade-offs for surveillance in exchange for public health, which is mediated by the perceived effectiveness of Health Code and changing views on the intentions of institutions who deploy it. We show how perceived competency varies not just on how well the technology works, but on the social and cultural enforcement of various non-technical aspects like quarantine, citizen data inputs, and cell reception. Furthermore, we illustrate how perceptions of Health Code are nested in people’s broader interpretations of disease control at the national and global level, and unexpectedly strengthen the Chinese authority’s legitimacy. None of the Chinese public, Health Code, or people’s perceptions toward Health Code are predetermined, fixed, or categorically consistent, but are co-constitutive and dynamic over time. We conclude with a theorization of a relational perception and methodological reflections to study algorithmic sociotechnical assemblages beyond COVID-19. (shrink)

The constructivist worldview divides all features in the world into purported external properties and the totality of experience and argues that they are all constructed. The constructivist worldview can also answer the problem of time and explain how the construction chain comes from nothing. Compared with the realist worldview, the constructivist worldview has multiple advantages.

The Tianqin, often a plucked zither or lute, holds significant cultural and musical heritage in China. The objective of this study is to explore the evolutionary perspectives on the culture of a Chinese folk musical instrument by examining its playing techniques and cultural changes. Conducted in Longzhou County, Guangxi Zhuang Autonomous Region, China, this study involved ethnographic fieldwork, including participant observation and interviews with key informants such as Tianqin musicians and craftsmen. Data analysis was performed using thematic analysis, revealing that (...) the Tianqin has transitioned from a ritualistic instrument to a symbol of cultural heritage and mass entertainment. The findings highlight the instrument's adaptability through innovations in playing techniques and materials, supported by governmental initiatives promoting Tianqin culture. This research underscores the importance of preserving and promoting traditional musical instruments in contemporary society. The study's insights contribute to a broader understanding of cultural adaptation and innovation in ethnomusicology. (shrink)

Integrating regulatory focus theory and personality literature, we develop and test a moderated mediation model to specify the underlying mechanisms and boundary conditions of the linkage between employee conscientiousness and job crafting. Two-wave data collected from 389 employees and 95 supervisors showed that: Employee conscientiousness had a positive effect on work promotion focus and work prevention focus. Employee conscientiousness was positively related to job crafting via work promotion focus, negatively related to job crafting via work prevention focus. Error management climate (...) positively moderated the relationship between employee conscientiousness and work promotion focus, negatively moderated the relationship between employee conscientiousness and work prevention focus. The indirect relationship between employee conscientiousness and job crafting through work promotion focus and work prevention focus were more pronounced respectively when the error management climate is higher rather than lower.

Food safety and food quality are two closely related aspects of the food management system. The difference between the two is that one keeps consumers safe while the other keeps consumers satisfied. This study examined the differences in how consumers value food safety and food quality with a focus on the influence of loss aversion on one’s psychological level and of income effect on one’s socio-demographic level. Our findings indicate that loss aversion and income effect significantly influence the way consumers (...) value food safety vs. quality labels when considering potential health risks and food price. High risk-averse and low-income consumers with strong loss aversion and a weak income effect show a higher demand for food safety labels as a way to ensure easy access to safety indications. Low risk-averse and high-income consumers with weak loss aversion and a strong income effect show a higher demand for food quality labels because they hope to gain more health benefits from high-quality food at good prices. This study provides insights that will assist public authorities and food industry in balancing food safety control and food quality improvement in order to meet the heterogeneous market demand changing alongside the transition of China’s food consumption and production.

One of the challenging problems in large scale cyber-argumentation platforms is that users often engage and focus only on a few issues and leave other issues under-discussed and under-acknowledged. This kind of non-uniform participation obstructs the argumentation analysis models to retrieve collective intelligence from the underlying discussion. To resolve this problem, we developed an innovative opinion prediction model for a multi-issue cyber-argumentation environment. Our model predicts users’ opinions on the non-participated issues from similar users’ opinions on related issues using intelligent (...) argumentation techniques and a collaborative filtering method. Based on our detailed experimental results on an empirical dataset collected using our cyber-argumentation platform, our model is 21.7% more accurate, handles data sparsity better than other popular opinion prediction methods. Our model can also predict opinions on multiple issues simultaneously with reasonable accuracy. Contrary to existing opinion prediction models, which only predict whether a user agrees on an issue, our model predicts how much a user agrees on the issue. To our knowledge, this is the first research to attempt multi-issue opinion prediction with the partial agreement in the cyber-argumentation platform. With additional data on non-participated issues, our opinion prediction model can help the collective intelligence analysis models to analyze social phenomena more effectively and accurately in the cyber argumentation platform.

This study mainly focuses on the emotion analysis method in the application of psychoanalysis based on sentiment recognition. The method is applied to the sentiment recognition module in the server, and the sentiment recognition function is effectively realized through the improved convolutional neural network and bidirectional long short-term memory model. First, the implementation difficulties of the C-BiL model and specific sentiment classification design are described. Then, the specific design process of the C-BiL model is introduced, and the innovation of the (...) C-BiL model is indicated. Finally, the experimental results of the models are compared and analyzed. Among the deep learning models, the accuracy of the C-BiL model designed in this study is relatively high irrespective of the binary classification, the three classification, or the five classification, with an average improvement of 2.47% in Diary data set, 2.16% in Weibo data set, and 2.08% in Fudan data set. Therefore, the C-BiL model designed in this study can not only successfully classify texts but also effectively improve the accuracy of text sentiment recognition. (shrink)

In the last 20 years, much attention has been paid to learners’ demotivation. Researchers have conducted many studies on second/foreign language learning demotivation from the perspectives of social culture, social psychology, and so forth. In China, related studies have mainly focused on college students’ demotivation; scant attention has been paid to senior high school students. Regarding scale development, although much progress has been made, there remains a need for a scale with high reliability and validity that is suitable for students (...) in the basic education stage. Therefore, based on previous studies and choosing Chinese senior high school students as participants, this research study developed a scale with 55 items, and exploratory factor analysis (EFA) was used to develop a 28-item scale with six dimensions. The six-dimensional construct encompasses teacher knowledge, important others, teacher responsibility, learner-related factors, learning contents, and critical incidents, which are the key factors leading to English learners’ demotivation. Among them, the factor of critical incidents is new and has been overlooked by other researchers. Moreover, the descriptive analysis demonstrated the degree to which the demotivators influence learners, and the independent samplest-test found a significant difference in the impact of critical incidents in terms of the students’ language proficiency. Ultimately, four suggestions are put forward to remotivate and sustain learners’ motivation. (shrink)

Physical literacy has received considerable attention in the field of physical education and physical activity worldwide. According to recent studies, the level of physical fitness among Chinese university students is gradually decreasing. This study aims to examine the impact of the PF level on PA and PL, as well as the relationships among PF, PA, and PL, in Chinese university students. Participants comprised 798 university students in Chongqing, China. Participants completed the tests of vital capacity, cardiorespiratory fitness, muscular strength, and (...) flexibility, according to the National Physical Fitness Measurement Standards Manual, as well as questionnaires on PA and PL. The independent t-tests were conducted to examine sex differences in the evaluated variables, and the Pearson’s correlation between each PF test and PL attributes and PA was calculated according to sex. In addition, the independent t-tests were conducted to determine whether the PF level had an effect on PL attributes and PA at various intensities. Significant sex differences were found in the PF domains of vital capacity, muscular strength, and aerobic fitness, with higher scores in men than in women, but not in the PF domain of flexibility and total PL score. Furthermore, the PF domains of muscular strength and aerobic fitness were significantly and positively correlated with the PL attributes of confidence and physical competence in both men and women, while the PF domains of vital capacity and aerobic fitness were significantly and positively correlated with the PL attribute of motivation in men. In addition, PL was significantly and positively associated with cardiorespiratory fitness, vital capacity, muscular strength, and flexibility among participants in the fit group. These findings support advocating for increased participation in PA in university students and using PL as a tool to improve PF components. (shrink)

Linear regression and its variants have been widely used for classification problems. However, they usually predefine a strict binary label matrix which has no freedom to fit the samples. In addition, they cannot deal with complex real-world applications such as the case of face recognition where samples may not be linearly separable owing to varying poses, expressions, and illumination conditions. Therefore, in this paper, we propose the kernel negative ε dragging linear regression method for robust classification on noised and nonlinear (...) data. First, a technique called negative ε dragging is introduced for relaxing class labels and is integrated into the LR model for classification to properly treat the class margin of conventional linear regressions for obtaining robust result. Then, the data is implicitly mapped into a high dimensional kernel space by using the nonlinear mapping determined by a kernel function to make the data more linearly separable. Finally, our obtained KNDLR method is able to partially alleviate the problem of overfitting and can perform classification well for noised and deformable data. Experimental results show that the KNDLR classification algorithm obtains greater generalization performance and leads to better robust classification decision. (shrink)

The present longitudinal survey study explored changes in and effects of foreign language classroom anxiety and listening anxiety on Chinese undergraduate students’ English proficiency over a semester in the COVID-19 context. A set of 182 matching questionnaires was collected from first-year undergraduate English as a foreign language learners at two time points of a 16-week semester. Analyses of the data revealed the following major findings: the participants experienced high levels of FLCA and FLLA both at the beginning and end of (...) the semester, neither of which changed significantly during the semester, FLCA and FLLA were highly positively related to each other, FLCA and FLLA significantly predicted students’ self-rated proficiency in listening and speaking English, and confidence in using English, efforts and motivation to learn English and interaction with instructors and peers mediated FLCA and FLLA to exert effects on students’ self-perceived proficiency in listening and speaking English. These findings indicate that the learning environment is critical in influencing the levels of and changes in FLCA and listening anxiety and that these two types of foreign language anxiety are serious issues in the pandemic foreign language learning context.

In the context of China’s supply-side structural reform and the concept of green development, we introduce the energy and environmental factors into the analytical framework of the total factor productivity of the logistics industry and use the Global Malmquist–Luenberger index method to analyze the evolution trend and heterogeneity of green TFP in the logistics industry of 30 provinces in China from 2003 to 2017. The results show that, firstly, the green TFP and traditional TFP of China’s logistics industry are both (...) on the rise and the absence of energy and environmental factors will lead to the overestimation of TFP of the logistics industry. Whether it is green TFP or traditional TFP, the main source of its growth is technical progress. Secondly, there is obvious regional heterogeneity in green TFP of logistics industry. Under the three regional division standards, the average annual growth rate of green TFP is from high to low in the order of eastern, western, and central regions. Under the eight regional classification standards, the eastern coastal economic zone, the southern coastal zone, the northern coastal zone, the northeast region, the middle reaches of the Yellow River, the southwest region, the middle reaches of the Yangtze River, and the northwest region are in order from high to low. Thirdly, there is obvious interprovincial heterogeneity in green TFP of the logistics industry. The highest growth rate of green TFP is in Zhejiang, followed by Jiangsu and Guangdong, and the slowest growth rate is in Chongqing. The technical progress of logistics industry in most provinces contributes more to the growth of green TFP. Fourthly, the differences of green TFP in the three regions of the east, center, and west are shrinking, which may be σ convergence, but the differences among the three regions are expanding. Compared with the existing literature, this paper applies the measurement framework of green TFP to China’s logistics industry and investigates the regional and provincial heterogeneity of green TFP in logistics industry. The conclusions are significant to understand and grasp the heterogeneity of green TFP growth in China’s logistics industry under environmental constraints and how to promote the development of green logistics in China.

This paper investigates a stochastic two-patch predator-prey model with ratio-dependent functional responses. First, the existence of a unique global positive solution is proved via the stochastic comparison theorem. Then, two different methods are used to discuss the long-time properties of the solutions pathwise. Next, sufficient conditions for extinction and persistence in mean are obtained. Moreover, stochastic persistence of the model is discussed. Furthermore, sufficient conditions for the existence of an ergodic stationary distribution are derived by a suitable Lyapunov function. Next, (...) we apply the main results in some special models. Finally, some numerical simulations are introduced to support the main results obtained. The results in this paper generalize and improve the previous related results. (shrink)

Long distance travel is an unusual activity for humans. The economical cabin environment during the long haul flights causes discomfort and even stress for many passengers. In-flight video and music systems are commonly available to improve the comfort level of the passengers. However, current in-flight music systems do not explore how the content can be used to reduce passengers stress. Most of these systems are designed and implemented assuming a homogeneous passenger group that has similar tastes and desires. In this (...) paper, we present a heart rate controlled in-flight music recommendation system for reducing the stress during air travel. The system recommends personalized music playlists to the passengers and attempts to keep their heart rate in a normal range with these playlists. Experiments in a simulated long haul flight cabin environment find that the passengers’ stress can indeed be significantly reduced through listening to the recommended music playlists. (shrink)

Taking Chinese listed companies from 2009 to 2017 as the research objects, this paper aims at exploring the heterogeneous effect of short-term and long-term institutional investors on stock mispricing. The empirical study finds that long-term institutional investors have an inhibiting effect on stock mispricing, while short-term institutional investors have an opposite effect. When the company information opacity is high, long-term institutional investors have a more obvious inhibiting effect on stock mispricing while short-term institutional investors have a more obvious promoting effect (...) on stock mispricing. When the attention of analysts is enhanced, long-term institutional investors further restrain the stock mispricing while short-term institutional investors further promote the stock mispricing.

Out of 288 Hong Kong cancer patients, 92.3% include themselves in decision-making, 71% prefer joint decision-making: with family, with doctor, with doctor plus family, with family minus doctor, and with doctor minus family. <5% want decision-making by “doctor-alone” and <1% desire decision-making by “family-alone”. Harmony, communication and responsibility are reasons for family participation. Most patients prefer “specialist” for information, followed by “family”, “friends”, and “GP”. Trust in doctors and prospects for controlling/curing disease are important factors in decision-making. Patients want to (...) participate and be listened to rather than make decisions. Doctors should not disclose information to family without patients’ permission, nor withhold information from patient [End Page 109] on family’s request. Only 25% of patients have discussed post-competent treatment with others and 7% have heard of Advance Directive ; 24% refuse to discuss it. After AD has been explained to them, 66% remain reluctant to sign one, preferring to leave oral instructions or appoint family as proxy decision-makers. The family’s decision-making role increases when patients become incompetent. The top reason for signing AD is to receive preferred post-competent treatments, and for not signing it, difficulty with making a prospective decision. The implications of these findings will be discussed. (shrink)

Smart grids are rolling out internationally, with the United States nearing completion of a significant USD4-plus-billion federal program funded under the American Recovery and Reinvestment Act. The emergence of smart grids is widespread across developed countries. Multiple approaches to analyzing the benefits of smart grids have emerged. The goals of this white paper are to review these approaches and analyze examples of each to highlight their differences, advantages, and disadvantages. This work was conducted under the auspices of a joint U.S.-China (...) research effort, the Climate Change Working Group Implementation Plan, Smart Grid. We present comparative benefits assessments of smart grid demonstrations in the U.S. and China along with a BA of a pilot project in Europe. In the U.S., we assess projects at two sites: the University of California, Irvine campus, which consists of two distinct demonstrations: Southern California Edison’s Irvine Smart Grid Demonstration Project and the UCI campus itself; and the Navy Yard area in Philadelphia, which has been repurposed as a mixed commercial-industrial, and possibly residential, development. In China, we cover several smart-grid aspects of the Sino-Singapore Tianjin Eco-city and the Shenzhen Bay Technology and Ecology City. In Europe, we look at a BA of a pilot smart grid project in the Malagrotta area west of Rome, Italy, contributed by the Joint Research Centre of the European Commission. The Irvine sub-project BAs use the U.S. Department of Energy Smart Grid Computational Tool, which is built on methods developed by the Electric Power Research Institute. The TEC sub-project BAs apply Smart Grid Multi-Criteria Analysis developed by the State Grid Corporation of China based on the analytic hierarchy process with fuzzy logic. The B-TEC and TNY sub-project BAs are evaluated using new approaches developed by those project teams. JRC has adopted an approach similar to EPRI’s but tailored to the Malagrotta distribution grid.

This paper investigates the exponential synchronization of complex dynamical networks based on the sampled-data control method. The sampled-data control means that the control input remains unchanged for a long time after each sampling, which can reduce the sampling number. By using the stability theory of the dynamical systems, this paper provides a novel sampling controller and estimates the bound of the sampling interval. Finally, a numerical example is given to demonstrate the effectiveness of the proposed design technique.

In recent years, somatosensory interaction technology, represented by Microsoft’s Kinect hardware platform, has been widely used in various fields, such as entertainment, education, and medicine. Kinect technology can easily capture and record behavioral data, which provides new opportunities for behavioral and psychological correlation analysis research. In this paper, an automatic decision-style recognition method is proposed. Experiments involving 240 subjects were conducted to obtain face data and individual decision-making style score. The face data was obtained using the Kinect camera, and the (...) decision-style score were obtained via a questionnaire. To realize automatic recognition of an individual decision-making style, machine learning was employed to establish the mapping relationship between the face data and a scaled evaluation of the decision-making style score. This study adopts a variety of classical machine learning algorithms, including Linear regression, Support vector machine regression, Ridge regression, and Bayesian ridge regression. The experimental results show that the linear regression model returns the best results. The correlation coefficient between the linear regression model evaluation results and the scale evaluation results was 0.6, which represents a medium and higher correlation. The results verify the feasibility of automatic decision-making style recognition method based on facial analysis. (shrink)
