ObjectivesUnder the COVID-19 prevention and control policy, online learning has been widely used. The current study aimed to identify latent profiles of self-regulated learning in the context of online mathematics learning during the recurrent outbreak of COVID-19, and examine the mechanisms underlying the relationship between self-regulated learning and online mathematics learning engagement among Chinese junior high school students using variable-and person-centered approaches.MethodsA sample of 428 Chinese junior high school students completed questionnaires on self-regulated learning, perceived academic control, and learning engagement. (...) Mplus7.0 was used to analyze the latent classes of self-regulated learning. A mediation model was conducted using the software SPSS PROCESS macro.ResultsThree profiles of self-regulated learning were identified and named as low self-regulated learning, medium self-regulated learning, and high self-regulated learning. In the mediating analysis, results of the variable-centered approach showed that perceived academic control mediated the effects of self-regulated learning on learning engagement. For the person-centered approach, we selected the low self-regulated learning type as the reference profile, and the analysis revealed that compared with the reference profile, perceived academic control partially mediated the link between the medium self-regulated learning profile and learning engagement; perceived academic control partially mediated the relationship between the high self-regulated learning profile and learning engagement.ConclusionThis study showed the heterogeneity in the online mathematics self-regulated learning patterns of Chinese junior high school students during the COVID-19 pandemic, revealing the internal mechanisms of Chinese junior high school students’ online mathematics learning engagement using variable-and person-centered approaches. Furthermore, the findings of the study have important implications for promoting online mathematics learning engagement among junior high students during the pandemic. (shrink)

The relationship between metacognition and mindreading was investigated by examining how well one can monitor their own learning compared to another person’s learning. Here, we used functional near-infrared spectroscopy to systematically investigate the brain area activation during metacognition and mindreading. The evidence indicated that metacognition and mindreading are underpinned by distinct neural systems. Metacognition is associated with activation in brain regions important for memory retrieval, such as the fusiform gyrus, while mindreading is associated with activation in brain regions important for (...) understanding and reasoning about others’ intentions, such as the right temporoparietal junction.

ObjectivesTo simulate hemodynamic changes after extraluminal compression in pulsatile tinnitus patients with a prominent transverse-sigmoid sinus junction.MethodsOne patient-specific case was reconstructed based on computed tomography venography images of a PT patient. The compression degree served as a new index in this study. Cases with 10, 20, 30, 40, 50, 60, 70, 80, and 90% of the compression degree of the control subject were constructed. Steady-state computational fluid dynamics were assessed. The wall pressure distribution, wall maximum pressure and flow pattern of (...) the PTSJ were calculated to evaluate hemodynamic differences among all cases.ResultsWith increasing compression, the wall pressure at the compression point and downstream of the PTSJ decreased but increased upstream. When the compression degree exceeded 70%, the upstream pressure increased significantly. Above 50% compression, the blood flow pattern downstream of the sigmoid sinus tended to spiral, especially after 80% compression. Beyond 60% compression, the blood flow pattern under the compression axis became more medial.ConclusionMechanical compression of PTSJ changes wall pressure and blood flow patterns. The degree of compression should be carefully observed to avoid possible complications or reoccurrence. (shrink)

BackgroundAt present, adherence to antipsychotic treatment is often poor, leading to the recurrence of symptoms. This increases the likelihood of the patient experiencing disability and thus increases the disease burden for the patient, their family, and society as a whole. However, to date, there is no clear evidence regarding the effect of medication adherence interventions on outcomes for patients with schizophrenia. Moreover, the traditional intervention methods are limited by manpower and resources in low- and middle-income countries. Recent studies have demonstrated (...) that increasing a patient’s level of self-compassion may improve their treatment adherence. Online mental health care interventions have advantages in terms of feasibility and acceptability for patients with schizophrenia. In this regard, a WeChat-based self-compassion training protocol to improve patient treatment adherence was designed in this study and will be evaluated in the future to determine its impact on patients with schizophrenia.MethodsThe protocol for the randomized controlled trial is based on the SPIRIT 2013 statement. This parallel RCT will aim to recruit 392 patients with schizophrenia who will be randomized at a 1:1 ratio into a 3-week intervention or control group. Both groups will receive routine care. The intervention group will also receive WeChat-based self-compassion training, which requires participants to complete three tasks every day, including a reading task, a meditation task, and a self-compassion journal task. The control group will receive WeChat-based psychological health education, which will only require participants to read positive articles about psychological health every day. Medication adherence, self-compassion, stigma, and social support will be measured at baseline, immediately after the intervention, and 3 weeks after the intervention. Program feasibility will be evaluated throughout the course of the study, and acceptability will be measured immediately after the intervention.Expected results:The intervention described here will address the barriers to accessing mental health care for people with schizophrenia, including patients’ desire for independent management, difficulty accessing providers, and concerns about privacy and stigma. The current study provides guidance for clinical nurses to carry out psychological intervention, with the ultimate aim of addressing the problems associated with a shortage of psychological professionals in low- and middle-income countries.

Objectives: The corona virus disease-2019 pandemic spread globally, and we aimed to investigate the psychosocial impact on healthcare workers in China during the pandemic.Methods: In this systematic review and meta-analysis, we searched seven electronic databases for cross-sectional studies on psychosocial impact on HWs in relation to COVID-19 from January 1, 2020 to October 7, 2020. We included primary studies involving Chinese HWs during the pandemic, and data were extracted from the published articles. Our primary outcome was prevalence of anxiety, depression, (...) and stress disorders. We pooled prevalence value with their 95% confidence interval using random effect models and assessed study quality on the basis of an 11-item checklist recommended by the Agency for Healthcare Research and Quality. The study protocol was registered in PROSPERO.Results: We identified 25 articles comprising a total of 30,841 completed questionnaires and 22 studies for meta-analysis. The prevalence of anxiety, depression, and stress disorders was 34.4%, 31.1%, and 29.1% for HWs. The pooled prevalence of anxiety disorders for HWs from late January to early February was 46.4%, significantly higher than those in mid-term February and after late February. The pooled prevalence of depression disorders for HWs from late January to early February was 46.5%, significantly higher than those in mid-term February and after late February. HWs working in Hubei Province had a higher prevalence of anxiety and a lower prevalence of depression than those working in other regions. Nurses had a higher prevalence of anxiety and depression than other HWs.Conclusions: About one-third of HWs in China suffered anxiety, depression, and stress at the early epidemic of COVID-19. HWs in Hubei Province, especially nurses, had a higher prevalence of psychological disorders. During the pandemic, a negative psychological state may persist in a proportion of Chinese HWs, fluctuating with the control of the pandemic. The long-term impact should continue to be observed. Attention should be paid to HWs for their psychological impact due to the pandemic.Systematic Review Registration: The study protocol was registered with PROSPERO. (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)

In recent decades, Kant's philosophy of law has increasingly moved into the focus of moral-philosophical discussions. In this context, the "Naturrecht Feyerabend" is of particular importance. On the one hand, it is the only surviving transcription of the lectures on natural law that Kant gave twelve times between 1767 and 1788; on the other hand, it is based on his lectures in the summer semester of 1784 and thus provides important evidence of Kant's reflections during an important phase in the (...) development of his moral philosophy. Despite this special significance, the text has received little attention in previous research. Dieter Hüning, Stefan Klingner and Gianluca Sadun Bordoni present here a volume that emphasizes this special significance. The ten contributions in the volume ask about the relationship of "Naturrecht Feyerabend" to the tradition of natural law as well as its relationship to critical moral philosophy and the late "Doctrine of Right". Contributors are: Manfred Baum, Franz Hespe, Philipp-Alexander Hirsch, Dieter Hüning, Stefan Klingner, Markus Kohl, Gabriel Rivero, Gianluca Sadun Bordoni, Michael Städtler, and Gideon Stiening.

Yi Hwang is Korean giant Bo of Neo-Confucianism, Zhu Xi as their study to cases. He was the author severely criticized Wang Yangming. Lee Hwang and odd peak on the "four-terminal impassioned" debate, both sides quoted Zhu's literature as an argument, and from that perspective loyal to Zhu. However, in essence is, Yi Hwang on Mencius' four-terminal, "said Zhu interpretation presupposes a set of different teachings of Confucianism system architecture, though Mencius in line with the text, but out of Zhu (...) Xi's basic position. This is one of the most crucial question is: "truth" can activities? In Zhu's of Science, the reason why is gas, there are not only activities. Based on the literature that: Yi Hwang in the interpretation of Zhu Xi's theory of qi, intentionally or unintentionally give reasons when an activity, while escaping the structure of Zhu Xi of Science. As a leading representative of Korean Confucianism, Yi T'oegye generally adhered to Zhu Xi's philosophical viewpoint, also writing several essays criticizing Wang Yang-ming's differences with Zhu Xi. In the debate between Yi T'oegye and his contemporary, Ki Kobong on the "Four Buddings" and the "Seven Emotions," both sides appealed to Zhu Xi's texts in the belief that they were being faithful to Zhu Xi's standpoint. But in fact, Yi's interpretation of "Four Buddings" presupposes a philosophical framework that differs from that of Zhu Xi. In this Yi deviates from Zhu Xi's standpoint, although he remains faithful to Mencius' texts. The key point of this debate lies in the question of whether "li" can be active. In Zhu Xi's philosophical framework, "li" as the ontological ground for "qi" has mere being but not activity. In this paper I demonstrate that in his interpretation of Zhu Xi's doctrine of "li" and "qi," Yi unconsciously ascribes a kind of activity to "li "and hence deviates from Zhu Xi's original philosophical position.

Abstract:Translating and commenting on two poems by Han Bo, “Modern Organ” and “The Big Killer,” that both focus on techno-scientific modernity and anxiety in the contemporary time and its impact on female subjectivity, this essay reflects on such an asymmetrically gendered burden of modern material progress to show that the embedded and added patriarchal obstacles, undeniably there, should be taken seriously. How, then, to achieve a more balanced gender equality in the modern time is a question that remains challenging for (...) all. (shrink)

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)

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)

As literary scholars, we are often puzzled by these questions raised from among the reading public: What is the meaning of this literary work? How does the author express his/her intention to portray the characters or narrate the story? How shall we as literary critics interpret the meaning of the literary work? Can a certain literary work have only one meaning? Obviously this is not the case. In order to answer the above questions, we present this special cluster of articles (...) to readers.Péter Hajdu says pertinently in his essay, "We may suppose that the meaning of a literary text comes from somewhere, but we should not imagine that there is only one source it comes from." Thus, to Hajdu, meaning can have many... (shrink)

In the complex environment, the suddenly changing structural parameters and abrupt actuator failures are often encountered, and the negligence or unproper handling method may induce undesired or unacceptable results. In this paper, taking the suddenly changing structural parameters and abrupt actuator failures into consideration, we focus on the robust adaptive control design for a class of heterogeneous Takagi–Sugeno fuzzy nonlinear systems subjected to discontinuous multiple uncertainties. The key point is that the switch modes not only vary with the system time (...) but also vary with the system states, and the intrinsic heterogeneous characteristics make it difficult to design stable controllers. Firstly, the concepts of differential inclusion are introduced to describe the heterogeneous fuzzy systems. Meanwhile, a fundamental lemma is provided to demonstrate the criteria of the boundness for a Filippov solution. Then, by using the set-valued Lie derivative of the Lyapunov function and introducing a vector of specific continuous functions, the closed-loop T-S fuzzy differential inclusion systems are proved to be ultimately bounded. The sufficient conditions for system stability are derived in term of linear matrix inequalities, which can be solved directly. Finally, a numerical example is provided to illustrate the effectiveness of the proposed control algorithm. (shrink)
