BackgroundMore than 15% of Chinese respondents reported somatic symptoms in the last week of January 2020. Promoting resilience is a possible target in crisis intervention that can alleviate somatization.ObjectivesThis study aims to investigate the relationship between resilience and somatization, as well as the underlying possible mediating and moderating mechanism, in a large sample of Chinese participants receiving a crisis intervention during the coronavirus disease 2019 epidemic.MethodsParticipants were invited online to complete demographic information and questionnaires. The Symptom Checklist-90 somatization subscale, 10-item (...) Connor–Davidson resilience scale, and 10-item Perceived Stress Scale were measured.ResultsA total of 2,557 participants were included. Spearman correlation analysis revealed that lower resilience was associated with more somatic symptoms. The conditional process model was proved. The interaction effects between perceived stress and sex predicted somatization.ConclusionResilience is a key predictor of somatization. The mediating effects of perceived stress between resilience and somatization work in the context of sex difference. Sex-specific intervention by enhancing resilience is of implication for alleviating somatization during the coronavirus disease 2019 epidemic. (shrink)
ObjectiveThe large-scale epidemic of Coronavirus Disease 2019 has triggered unprecedented physical and psychological stress on health professionals. This study aimed to investigate the prevalence and risk factors of burnout syndrome, and the relationship between burnout and depressive symptoms among frontline medical staff during the COVID-19 epidemic in China.MethodsA total of 606 frontline medical staff were recruited from 133 cities in China using a cross-sectional survey. The Maslach Burnout Inventory was used to assess the level of burnout. Depressive symptoms were assessed (...) by the Patient Health Questionnaire Depression.ResultsDuring the COVID-19 pandemic, 36.5% of the medical staff experienced burnout. Personal and work-related factors were independently associated with burnout, including age, family income, having physical diseases, daily working hours, and profession of nurse. The correlation coefficients between the scores of each burnout subscale and the scores of depressive symptoms were 0.57 for emotional exhaustion, 0.37 for cynicism, and −0.41 for professional efficacy.ConclusionsOur findings suggest that the prevalence rate of burnout is extremely high among medical staff during the COVID-19 pandemic, which is associated with other psychological disorders, such as depression. Psychological intervention for medical staff is urgently needed. Young and less experienced medical staff, especially nurses, should receive more attention when providing psychological assistance.

Background: Previous systematic review indicated the prevalence of prenatal anxiety as 14–54%. Pregnant women are a high-risk population for COVID-19. However, the prevalence of anxiety symptoms and related factors is unknown in Chinese pregnant women during COVID-19 outbreak.Objective: To investigate the prevalence of anxiety symptoms and the related factors in Chinese pregnant women who were attending crisis intervention during the COVID-19 pandemic.Methods: The data of this cross-sectional study were collected in about 2 months. Data analysis was performed from April to (...) May 2020. Participants completed a set of questionnaires via the Wechat Mini-program before starting the online self-help crisis intervention for COVID-19 epidemic. A total of 2,120 Chinese pregnant women who were attending a self-help crisis intervention participated in this study. A survey was developed to address possible stress-related factors in pregnant women during the COVID-19 outbreak, including demographic, socioeconomic, and pregnancy-related factors, as well as COVID-19 related factors. Generalized Anxiety Disorder-7 scale and the 10-item perceived stress scale were, respectively, employed to measure anxiety and stress-related factors.Results: A total of 21.7% of pregnant women reported at least mild anxiety, and only 82 women reported moderate to severe anxiety. Factors associated with at least mild anxiety included living in Hubei province, nobody providing everyday life support, pelvic pain or vaginal bleeding, and higher perceived stress. Having relatives or neighbors with a diagnosis of COVID-19 was not associated with anxiety.Conclusions and Relevance: Our findings indicate that evaluation and intervention for maternal and infant health are necessary in pregnant women with anxiety during COVID-19 epidemic, especially those with higher perceived stress, less everyday life support, or vaginal bleeding. Interactions among these related medical, social and psychological factors need to be investigated in future studies. (shrink)
Using Chinese listed companies as research setting, this paper constructs a measure of corporate competing culture through textual analysis on firms’ management discussion and analysis disclosures, and examines the impact of corporate competing culture on environmental investment. The results show that competing culture has a significant and positive impact on firms’ environmental investment, and the results remain robust to a battery of robustness tests. Moreover, the mediating analysis indicates that competing culture promotes corporate environmental investment through enhancing firms’ internal control (...) quality. Furthermore, the heterogeneity results show that the positive impact of corporate competing culture on environmental investment is more pronounced in firms with larger size, stronger corporate governance, in high-polluting industry, and located in less developed regions. Our findings shed light on the importance of corporate competing culture and provide practical implications for corporate sustainable development. (shrink)
The gas accumulation mode can be divided into two types based on the migration and accumulation characteristics: discontinuous accumulation into the reservoir rocks and continuous accumulation within or adjacent to the source rocks. Correspondingly, there are three different gas reservoirs including conventional, unconventional, and those in a transitional state. To demonstrate the differences in the formation mechanisms and distribution features of the two accumulation types, we have scrutinized the continuous accumulation and discontinuous accumulation in the Hangjinqi area of the Ordos (...) Basin in North China. Continuous gas accumulation and discontinuous accumulation are, respectively, distributed in the southern and northern regions of the Hangjinqi area, which may change with the source-rock quality, migration force, reservoir capacity, and trapping condition. We identified that the essential factors influencing the formation and current distribution of gas reservoirs are the hydrocarbon generation ability, porosity, and cap rock-trap combinations in the study area. An ideal complete gas reservoir sequence develops coalbed methane, shale gas, basin central gas, water soluble gas, and conventional gas reservoirs from the center to the edge of the basin. Understanding the distribution characteristics of continuous accumulation and discontinuous accumulation allows better prediction of the potential gas reservoir types with the knowledge of discovered reservoirs. We recommend exploring anticline gas reservoirs in areas north of the Boerjianghaizi fault and basin-centered gas reservoirs in areas south of the Boerjianghaizi fault. We also suggest performing further research on shale source rocks because the maturity and the burial depth of the marine-continental organic-rich shale in the Shanxi-Taiyuan Formations are recognized to be favorable for shale gas generation and preservation.

BackgroundThe effects of psychological interventions on symptoms and psychology of functional dyspepsia remain unclear. We aimed to comprehensively evaluate the effects of psychological interventions on symptoms and psychology of FD.MethodsWe searched the PubMed, Cochrane Library, and Embase electronic databases for randomized controlled trials evaluating the role of psychological interventions in FD patients published before July 2021. Standardized mean differences, risk ratios and 95% confidence intervals were calculated by a random effects model. Subgroup analyses and sensitivity analyses were also performed.ResultsFourteen RCTs (...) with a total of 1,434 FD patients were included. Compared with the control group, psychological interventions were significantly more likely to symptom improvement [RR = 1.74, 95% CI, p = 0.01], relieve gastrointestinal symptoms scores at follow up [SMD = −1.06, 95% CI, p < 0.0001], relieve gastrointestinal symptoms scores at end of treatment [SMD = −0.98, 95% CI, p < 0.001], decrease anxiety [SMD = −0.8, 95% CI, p = 0.006] and depression levels [SMD = −1.11, 95% CI, p < 0.001]. The results of the subgroup analysis showed that psychotherapy was more likely to symptom improvement, relieve gastrointestinal symptoms scores and decreased depression levels compared to the control.ConclusionsPsychological interventions may be effective in alleviating the symptoms and psychology of FD, but the effect appears to be limited to psychotherapy with fewer trials for other psychological interventions. More data from high-quality RCTs are needed to confirm their use in the treatment of FD. (shrink)
In this paper, the orbital stability of solitary wave solutions for the generalized Gardner equation is investigated. Firstly, according to the theory of orbital stability of Grillakis-Shatah-Strauss, a general conclusion is given to determine the orbital stability of solitary wave solutions. Furthermore, on the basis of the two bell-shaped solitary wave solutions of the equation, the explicit expressions of the orbital stability discriminants are deduced to give the orbitally stable and instable intervals for the two solitary waves as the wave (...) velocity changing. Moreover, the influence caused by the interaction between two nonlinear terms is also discussed. From the conclusion, it can be seen that the influences caused by this interaction are apparently when 0shrink)
This co-edited volume compares Chinese and Western experiences of engineering, technology, and development. In doing so, it builds a bridge between the East and West and advances a dialogue in the philosophy of engineering. Divided into three parts, the book starts with studies on epistemological and ontological issues, with a special focus on engineering design, creativity, management, feasibility, and sustainability. Part II considers relationships between the history and philosophy of engineering, and includes a general argument for the necessity of dialogue (...) between history and philosophy. It continues with a general introduction to traditional Chinese attitudes toward engineering and technology, and philosophical case studies of the Chinese steel industry, railroads, and cybernetics in the Soviet Union. Part III focuses on engineering, ethics, and society, with chapters on engineering education and practice in China and the West. The book’s analyses of the interactions of science, engineering, ethics, politics, and policy in different societal contexts are of special interest. The volume as a whole marks a new stage in the emergence of the philosophy of engineering as a new regionalization of philosophy. This carefully edited interdisciplinary volume grew out of an international conference on the philosophy of engineering hosted by the University of the Chinese Academy of Sciences in Beijing. It includes 30 contributions by leading philosophers, social scientists, and engineers from Australia, China, Europe, and the United States. (shrink)
Many neuroanatomical alterations have been detected in patients with tinnitus in previous studies. However, little is known about the morphological and structural covariance network changes before and after long-term sound therapy. This study aimed to explore alterations in brain anatomical and SCN changes in patients with idiopathic tinnitus using voxel-based morphometry analysis 24 weeks before and after sound therapy. Thirty-three tinnitus patients underwent magnetic resonance imaging scans at baseline and after 24 weeks of sound therapy. Twenty-six age- and sex-matched healthy (...) control individuals also underwent two scans over a 24-week interval; 3.0T MRI and high-resolution 3D structural images were acquired with a 3D-BRAVO pulse sequence. Structural image data preprocessing was performed using the VBM8 toolbox. The Tinnitus Handicap Inventory score was assessed for the severity of tinnitus before and after treatment. Two-way mixed model analysis of variance and post hoc analyses were performed to determine differences between the two groups and between the two scans. Student-Newman-Keuls tests were used in the post hoc analysis. Interaction effects between the two groups and the two scans demonstrated significantly different gray matter volume in the right parahippocampus gyrus, right caudate, left superior temporal gyrus, left cuneus gyrus, and right calcarine gyrus; we found significantly decreased GM volume in the above five brain regions among the tinnitus patients before sound therapy compared to that in the HC group. The 24-week sound therapy group demonstrated significantly greater brain volume compared with the baseline group among these brain regions. We did not find significant differences in brain regions between the 24-week sound therapy and HC groups. The SCN results showed that the left superior temporal gyrus and left rolandic operculum were significantly different in nodal efficiency, nodal degree centrality, and nodal betweenness centrality after FDR correction. This study characterized the effect of sound therapy on brain GM volume, especially in the left superior temporal lobe. Notably, sound therapy had a normalizing effect on tinnitus patients. (shrink)
Hydromechanical continuously variable transmission is capable of bearing large torque and has wide transmission range, which is suitable for high-power tractors. Dynamic characteristics could influence the tractor life, especially in a high-power tractor. Wet clutch is the crucial component in the HMCVT, which could smooth and soft power transmission. Therefore, it is important to study the dynamic characteristics and implement the wet clutch test of HMCVT. In this paper, AMESim is used to establish virtual models of gearbox, pump-controlled hydraulic motor (...) system, and shifting hydraulic system. Then, a simulation study of tractor operation under working condition is carried out. The internal and external meshing forces of the planetary row are analyzed. Finally, the wet clutch engagement process of HMCVT in the high-power tractor is tested to verify the oil pressure. The simulation results show that the values of internal and external meshing force become larger as the throttle opening increases. At the moment of shifting change, the meshing forces of the planetary gear have great impact. The clutch test shows that the trend of the oil filling curve obtained from the bench test is similar to that obtained from the theoretical curve, which verifies the simulation results. (shrink)
Recently, it was demonstrated that multitasking evolutionary algorithm, a newly proposed algorithm, can solve multiple optimization problems simultaneously through a single run, breaking through the limitations of traditional evolutionary algorithms, with good convergence and exploration performance. As a novel algorithm, MTEA still has a lot of unexplored space. Generally speaking, the order of solution variables has no significant influence on the single-tasking EAs. To our knowledge, the effect of the order of variables in the multitasking scenario has not been explored. (...) To fill in this research gap, three orders of variables in the multitasking scenario are proposed in this paper, including full reverse order, bisection reverse order, and trisection reverse order. An important feature of these orders of variables is that an individual can recover as himself after two times of changing the order of variables. In order to verify our idea, these orders of variables are embedded into MTEA. The experiment results revealed that the effect of the different orders of variables is universal but not significant enough in the practical application. Furthermore, tasks with high similarity and high degree of intersection are sensitive to the order of variables and get great impact between tasks. (shrink)
Marxist Philosophy in China is an important task is to use the basic theory of Marxist philosophy, viewpoint and method to sort, extract of traditional Chinese culture, philosophy. And the "legitimacy of Chinese philosophy," the discussion, while filling the job of "legitimacy" has also been a certain degree of skepticism. Including how to look at the cultural characteristics of Chinese philosophy, Western academic norms on how to look at the impact of Chinese philosophy and how to look at the transformation (...) of traditional Chinese philosophy, it is clear from the theoretical work to clarify the legality of the key. The main task of sinicizing Marxist philosophy is how to abstract philosophical thoughts from traditional Chinese culture with the guide of basic Marxist theories, viewpoints and methods. However, the validity problem of Chinese philosophy in a degree makes the validity of this project become a problem as well. How to understand the cultural identity of Chinese philosophy? How to evaluate the impact Western academic discourses left on Chinese philosophy? And how to judge the transformation of Chinese philosophy? We hold that theoretically, these three questions are the key points for the validity illumination of the project mentioned above. (shrink)
Video surveillance plays a vital role in maintaining the social security although, until now, large uncertainty still exists in danger understanding and recognition, which can be partly attributed to intractable environment changes in the backgrounds. This article presents a brain-inspired computing of attention value of surrounding environment changes with a processes-based cognition model by introducing a ratio valueλof EC-implications within considered periods. Theoretical models for computation of warning level of EC-implications to the universal video recognition efficiency are further established. Imbedding (...) proposed models into the online algorithms is suggested as a future research priority towards precision security for critical applications and, furthermore, schemes for a practical implementation of such integration are also preliminarily discussed.

In the process of rapid urbanization, urban heat island effect has been showing more and more significant impacts on human well-being. Therefore, a more detailed understanding of the impact of three-dimensional building morphology on UHI effect across a continuum of spatial scales will be necessary to guide and improve the human settlement.This study selected 31 provincial capital cities of mainland China to analyze the impacts of the 3D building morphology, including the number, area, height, volume, and the surface area of (...) the buildings, on the land surface temperature. By exploring how the influence of 3D building morphology on LST changes with the increase of spatial scale, this study finally recognized which 3D building morphology index is the most significant index affecting LST in different cities, and which spatial scale these 3D building morphology indexes have the most significant impact on LST. The results showed that the building area is the most important 3D building morphology parameter affecting the LST, while the building height has the slightest influence on the LST. These effects are more significant in the spatial scale of 150 m–540 m, and the spatial scale increases with the increase of building areas in developed cities. These results highlight the necessity of considering fine-grained management in the governance and alleviating of the urban thermal environment through urban planning and urban renewal strategies.

PurposeCollege students in the pandemic area are experiencing the problems caused by COVID-19 by themselves or people around them, how to cope with the sudden changes and adjust the psychological stress response, and get experience and grow in the fight against the pandemic is a question worth in-depth discussion. The researchers constructed a mediated regulation model to examine the effects of intrusive rumination on the creativity of college students during the COVID-19 pandemic, as well as the mediating effect of post-traumatic (...) growth and the moderating role of psychological resilience.MethodsA sample of 475 university students from Guangdong Province, China, were surveyed with the Runco Ideational Behavior Scale, the Event Related Rumination Inventory, the Posttraumatic Growth Inventory, and the Psychological Resilience Scale. SPSS and PROCESS were used for correlation analysis, mediation analysis, and mediated moderation analysis.Results Intrusive rumination was positively correlated with post-traumatic growth and creativity but negatively correlated with psychological resilience. Psychological resilience was positively correlated with post-traumatic growth and creativity. Post-traumatic growth and creativity were positively correlated. Post-traumatic growth played a mediating role in the relationship between intrusive rumination and creativity. Psychological resilience moderated the first half of the pathway “intrusive rumination → post-traumatic growth → creativity.”ConclusionIntrusive rumination affected creativity directly and also indirectly through post-traumatic growth. At the same time, psychological resilience played a moderating role between intrusive rumination and creativity. The correlation between intrusive rumination and post-traumatic growth was stronger when levels of psychological resilience levels were higher. (shrink)
This book presents a systematic account of the role of the personal spiritual ideal of wu-wei--literally "no doing," but better rendered as "effortless action"--in early Chinese thought. Edward Slingerland's analysis shows that wu-wei represents the most general of a set of conceptual metaphors having to do with a state of effortless ease and unself-consciousness. This concept of effortlessness, he contends, serves as a common ideal for both Daoist and Confucian thinkers. He also argues that this concept contains within itself a (...) conceptual tension that motivates the development of early Chinese thought: the so-called "paradox of wu-wei," or the question of how one can consciously "try not to try." Methodologically, this book represents a preliminary attempt to apply the contemporary theory of conceptual metaphor to the study of early Chinese thought. Although the focus is upon early China, both the subject matter and methodology have wider implications. The subject of wu-wei is relevant to anyone interested in later East Asian religious thought or in the so-called "virtue-ethics" tradition in the West. Moreover, the technique of conceptual metaphor analysis--along with the principle of "embodied realism" upon which it is based--provides an exciting new theoretical framework and methodological tool for the study of comparative thought, comparative religion, intellectual history, and even the humanities in general. Part of the purpose of this work is thus to help introduce scholars in the humanities and social sciences to this methodology, and provide an example of how it may be applied to a particular sub-field.

In two recent papers, Mr Robert Young maintains that all attempts by philosophers to bolster the-violation-of-law concept of miracles are bound to fail and propounds what he claims to be a novel non-reductivist concept of miracles which avoids the conceptual difficulties of the violation-model. His view of miracles is of god being ‘an active agent-factor in the set of factors which actually was causally operative’ [p. 123] in an event dubbed a miracle. God is put in among ‘the plurality of (...) causes’ [p. 122, S p. 33] that could determine the event, but if he acts in a miracle, then ‘his presence…alters the outcome from what it would have been if, contrary to fact , he had not been present’ [p. 122]. Young claims that his concept ‘is neither a violation of … laws nor is it a coincidental occurrence religiously interpreted’ [p. 122, S p. 33], and so it avoids the difficulties, which he thinks are faced by the violation-model, of having an intelligible notion of an occurrence of the physically impossible, and also the reductivism inherent in taking mere coincidences as miracles. He also suggests a procedure of settling the epistemological issue regarding particular alleged miracles, an inquiry he thinks he has made possible by having first given a sense to miracles. [p. 126]. (shrink)
In recent years, philosophical ideas developed during the Wei-Jin period, broadly referred to as xuanxue in Chinese and ‘Neo-Daoism’ or ‘Dark Learning’ in English, have been accorded increasing attention in academia. This article provides an introduction to some major thinkers of the Wei-Jin period, addressing both their original writings and recent scholarly interpretations. The article aims to demonstrate that many Wei-Jin period intellectuals formed their theories through reinterpreting the relationship between texts associated with Daoism and Confucianism. Thinkers of this period (...) often attempted to show how these defining ‘schools’ of pre-Qin Chinese thought did not propose theories that were fundamentally inconsistent, and that their ideas could be woven together as elements of a coherent view. This intellectual movement can thus be, and often has been, viewed as an attempt to integrate Daoism and Confucianism. However, a more nuanced reading demonstrates that these thinkers were reworking the relationship between what were seen as predominately Daoist or Confucian themes from their very foundation. Accordingly, the common description of Wei-Jin thinkers as ‘Daoist’ is decidedly incongruous. (shrink)

This essay develops an inferential account of model explanation, based on Mauricio Suárez’s inferential conception of scientific representation and Alisa Bokulich’s counterfactual account of model explanation. It is suggested that the fact that a scientific model can explain is essentially linked to how a modeler uses an established model to make various inferences about the target system on the basis of results derived from the model. The inference practice is understood as a two-step activity, with the first step involving making (...) counterfactual statements about the model itself and the second step involving making hypothetical statements transferring over claims derived from the model onto the target. To illustrate how this two-step activity proceeds, an agent-based simulation model is discussed. (shrink)
