We study the minimal enumeration degree problem in models of fragments of Peano arithmetic () and prove the following results: in any model M of Σ2 induction, there is a minimal enumeration degree if and only if M is a nonstandard model. Furthermore, any cut in such a model has minimal e-degree. By contrast, this phenomenon fails in the absence of Σ2 induction. In fact, whether every Σ2 cut has minimal e-degree is independent of the Σ2 bounding principle.

We study the jump hierarchy of d.c.e. Turing degrees and show that there exists a high d.c.e. degree d which does not bound any minimal pair of d.c.e. degrees.

The present study develops an artificial agent that plays the iterative chicken game based on a computational model that describes human behavior in competitive social interactions in terms of fairness. The computational model we adopted in this study, named as the self-concept fairness model, decides the agent’s action according to the evaluation of fairness of both opponent and self. We implemented the artificial agent in a computer program with a set of parameters adjustable by researchers. These parameters allow researchers to (...) determine the extent to which the agent behaves aggressively or cooperatively. To demonstrate the use of the proposed method for the investigation of human behavior, we performed an experiment in which human participants played the iterative chicken game against the artificial agent. Participants were divided into two groups, each being informed to play with either a person or the computer. The behavioral analysis results showed that the proposed method can induce changes in the behavioral pattern of human players by changing the agent’s behavioral pattern. Also, we found that participants tended to be more sensitive to fairness when they played with a human opponent than with a computer opponent. These results support that the artificial agent developed in this study will be useful to investigate human behavior in competitive social interactions. (shrink)

The COVID-19 pandemic at the beginning of 2020 has changed the conventional learning mode for most students at schools all over the world, and the e-learning at home has become a new trend. Taking Chinese college students as the research subject and drawing on the stimulus–organism–response model, this paper examines the relationship between the peer referent, perceived closeness, and perceived control and the learning engagement. Using data from 377 college students who have used e-learning, this study shows that perceived closeness, (...) perceived control, and peer referents in e-learning have a positive effect on the self-efficacy and well-being of students, thus improving students’ enthusiasm for learning. Our intent is to assist researchers, instructors, designers, and others in identifying effective methods to conceptualize and measure student engagement in e-learning. (shrink)

Yan Yuan (1635-1704) has long been a controversial figure in the study of Chinese intellectual and cultural history. Although marginalized in his own time largely due to his radical attack on Zhu Xi (1130-1200), Yan became elevated as a great thinker during the early twentieth century because of the drastic changes of modern Chinese intellectual climate. In Body, Ritual and Identity : A New Interpretation of the Early Qing Confucian Yan Yuan (1635-1704), Yang Jui-sung has demonstrated that the complexity (...) of Yan's ideas and his hatred for Zhu Xi in particular need be interpreted in light of his traumatic life experiences, his frustration over the fall of the Ming dynasty, and anxiety caused by the civil service examination system. Moreover, he should be better understood as a cultural critic of the lifestyle of educated elites of late imperial China. By critically analyzing Yan's changing intellectual status and his criticism that the elite lifestyle was unhealthy and feminine, this new interpretation of Yan Yuan serves to shed new light on our understanding of the features as well as problems of educated elite culture in late imperial China"--Provided by publisher.

BackgroundThe cognitive level of post-stroke aphasia patients is generally lower than non-aphasia patients, and cognitive impairment affects the outcome of stroke. However, for different types of PSA, what kind of cognitive assessment methods to choose is not completely clear. We investigated the Montreal Cognitive Assessment, the Mini-Mental State Examination, and the Non-language-based Cognitive Assessment to observe the evaluation effect of CI in patients with fluent aphasia and non-fluent aphasia.Methods92 stroke patients were included in this study. Demographic and clinical data of (...) the stroke group were documented. The language and cognition were evaluated by Western Aphasia Battery, MoCA, MMSE, and NLCA. PSA were divided into FA and NFA according to the Chinese aphasia fluency characteristic scale. Pearson’s product–moment correlation coefficient test and multiple linear regression analysis were performed to explore the relationship between the sub-items of WAB and cognitive scores. The classification rate of CI was tested by Pearson’s Chi-square test or Fisher’s exact test.ResultsThe scores of aphasia quotient, MoCA, MMSE, and NLCA in NFA were lower than FA. AQ was positively correlated with MoCA, MMSE, and NLCA scores. Stepwise multiple linear regression analysis suggested that naming explained 70.7% of variance of MoCA and 79.9% of variance of MMSE; comprehension explained 46.7% of variance of NLCA. In the same type of PSA, there was no significant difference in the classification rate. The classification rate of CI in NFA by MoCA and MMSE was higher than that in FA. There was no significant difference in the classification rate of CI between FA and NFA by NLCA.ConclusionMoCA, MMSE, and NLCA can be applied in FA. NLCA is recommended for NFA. (shrink)

This chapter discusses the relation between Mencius and “Daoism” by taking Zhuangzi (and other authors of the Zhuangzi) as representative of the latter and seeing where each of them stood in response to the cross-current of ideas of the Warring States period. The ideas of some figures mentioned in the Mencius, such as Gaozi, Yang Zhu, and Xu Xing, are extended in the Zhuangzi. Some ideas gathered in the Zhuangzi can be seen to contrast with Mencius’s and these are (...) referred to as “Daoist tendencies” of thought. For instance: self-preservation and nourishment of one’s own life, morality as an artificial construct, moral skepticism, tian (“heaven”) as non-normative, an ideal primitive life free from hierarchy, and that there is no essential (moral) human nature.

Lachlan observed that any nonzero d.c.e. degree bounds a nonzero c.e. degree. In this paper, we study the c.e. predecessors of d.c.e. degrees, and prove that given a nonzero d.c.e. degree , there is a c.e. degree below and a high d.c.e. degree such that bounds all the c.e. degrees below . This result gives a unified approach to some seemingly unrelated results. In particular, it has the following two known theorems as corollaries: there is a low c.e. degree isolating (...) a high d.c.e. degree [S. Ishmukhametov, G. Wu, Isolation and the high/low hierarchy, Arch. Math. Logic 41 259–266]; there is a high d.c.e. degree bounding no minimal pairs [C.T. Chong, A. Li, Y.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Great Synthesis of Wang Yang Ming Neo-Confucianism in Korea: The Chonŏn (Testament) by Chŏng Chedu (Hagok) by Edward Y.J. ChungMaria Hasfeldt Long (bio)The Great Synthesis of Wang Yang Ming Neo-Confucianism in Korea: The Chonŏn (Testament) by Chŏng Chedu (Hagok). By Edward Y.J. Chung. Landham: Lexington Books, 2020. Pp. vii+ 351. Hardcover $137.00, isbn 978-1-7936-1469-8. The Korean Neo-Confucian tradition during the Chosŏn dynasty (1392–1910) was dominated (...) by the orthodox Sŏngnihak (School of Human Nature and Principle), which is also known as the Chŏngjuhak (Cheng–Zhu School). This school of Neo-Confucianism followed the doctrines and teachings of the Great Synthesizer Zhu Xi (1130–1200) to such a point that other Neo-Confucian schools were labeled as wrong and even persecuted until the late nineteenth century. One of these schools was Simhak (School of the Mind/Heart) established by the Chinese scholar Wang Yangming (1472–1529), which during the Ming dynasty (1382–1644) had grown to rival the Cheng–Zhu school. However, the academic-political power of the Cheng–Zhu school in Korea managed to suppress Yangming scholarship and maintain dominance throughout the dynasty. Despite that, a few scholars did take up the scholarship of Simhak in Korea, with the most influential being Chŏng Chedu, also known as Hagok (1649–1736) (p. 4). In his book, The Great Synthesis of Wang Yang Ming Neo-Confucianism in Korea: The Chonŏn (Testament) by Chŏng Chedu (Hagok), Edward Y.J. Chung presents not only an annotated translation of Hagok's main writings but also a look into intellectual scholarship that opposed the orthodoxy of the Cheng–Zhu school of Korea. This in-depth study and translation of Hagok into English was motivated by the lack of attention in Western scholarship on Korean Neo-Confucianism. It presents a study that goes beyond the three most famous scholars, Yi Hwang T'oegye (1501–1570), Yi I Yulgok (1536–1584), and Chŏng Yagyong Tasan (1762–1836), who founded the three mainstream schools of the Chosŏn dynasty. According to Chung, Hagok's writing not only represents important aspects of intellectual history but also serves as a fourth and lesser-known school of Korean Neo-Confucian thinking that should be placed on the same level as the other three. Unlike other Korean scholars who tried to take up the Yangming doctrine, Hagok did not care that the doctrine was prohibited. This set him apart from other scholars. Despite the Cheng–Zhu school being the "right learning," Hagok did not agree with the majority of it and based his theories on the Yangming doctrine. Although Hagok openly followed the Yangming doctrine, he did not do so blindly. [End Page 1] Hagok was aware that Yangming's theories had their flaws and he agreed with some theories of the Cheng–Zhu school (p. 7–8). This resulted in him trying to synthesize the two schools into one harmonious doctrine, which is why Chung believes Hagok to be important and has undertaken the task of bringing attention to this Korean scholar. Consisting of two distinct parts, Chung gives the reader a solid introduction to Hagok and his main theories via the selected translations from his most influential text, Chonŏn, which can be translated into "testament" or "living words." The first part of the book is divided into notes on the translation itself, such as transliteration, citation style, abbreviations, and, more importantly, how and why Chung selected the sections of the Chonŏn that have been translated. Through the selection, translation, annotation, and discussion of forty-one important essays from Chonŏn's three parts, Chung wishes to show the heart of Hagok's Neo-Confucian thought (p. x). The Chonŏn is not organized according to any thematic system and consists of different paragraphs, notes, and comments. Chung has, therefore, chosen which parts to translate in order to best portray Hagok's interpretation of the key concepts, the theories found in the Yangming Neo-Confucianism, and Hagok's criticism of Zhu Xi and T'oegye. All of this is properly introduced and explained in... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Clinical CommentaryChong Siow Ann, Associate ProfessorDr. G appears to experiencing symptoms of schizophrenia, which is arguably the most severe mental disorder and which afflicts about one in a hundred people. This is a psychotic disorder that causes disturbances and distortions in thinking, including neurocognitive impairments, perception and behaviour. There is no cure for this often devastating disorder. Current antipsychotic medications can alleviate some of the symptoms but it often (...) comes at a price as these antipsychotics have burdensome side effects.A feature of this disorder is anosognosia, which is a lack of awareness or “insight” that an illness is present. This lack of insight presents a particular challenge because these individuals would, as in the case of Dr. G, refuse needed treatment as they do not perceive that they are ill. This is not necessarily an all-or-none phenomenon but is rather more complex and multidimensional; there might be an unawareness or recognition on behalf of the patient that they are suffering from a mental illness, the failure to appreciate the necessity of treatment; and/or the inability to recognise and define the psychotic symptoms like unusual thoughts and hallucinations as signs of illness1 and in many instances, all three are present. It is also by no means uncommon. Studies have found that between 60% and 80% of people with schizophrenia lack awareness of their illness to varying degrees.2This phenomenon remains an enigma. Some regard it as a form of psychological defence against the harsh reality of a psychotic illness — awareness of having a chronic and devastating illness might lead to demoralisation, hopelessness and suicide.3 Recent research, however, [End Page 250] indicates that this psychological denial plays a small part, if any, and instead has found an association with certain neuropsychological and neurocognitive deficits,4 as well as functional and structural brain abnormalities in the frontal lobe of the brain.5The prevailing clinical view thus is that this is an intrinsic and organic aspect of the schizophrenic illness which has nothing to do with wilfulness but rather the incapacity to perceive the presence of the illness. Edwin Fuller Torrey, an eminent psychiatrist and executive director of the Stanley Medical Research Foundation, calls anosognosia the “single largest reason why individuals with schizophrenia and bipolar disorder do not take their medications”, and he has remarked that “to keep talking about civil liberty is illogical. Patients are anything but free when they’re at the beck and call of their own delusions”.6It is also this view that it is a product of a brain disorder that some — particularly patients — find unacceptable. At one level, it does not take into context the person’s own experiences, and at a deeper level it calls into question the conception of the self with its capacity to exercise judgements and the autonomy to make decisions.This is a perennial ethical issue in psychiatry when people with severe mental illnesses refuse treatment. This becomes a Catch-22 situation where part of the illness that needs treatment is also preventing any treatment to be given: implicit in the principle of informed consent for treatment is that the person should be aware of the nature and course of their illness and acknowledge the need for treatment. While there are laws for involuntary commitment, the bar is usually high in that there must be a clear and present risk of harm to the person or others. Alan Stone, a professor of law and psychiatry at Harvard University proposed a possible justification for involuntary treatment based on his “thank-you theory” which assumes that patients will become well and subsequently agree that the intervention was in their best interests but research suggests that only half of these patients would admit so.7One suggested mechanism is the use of advance directives — psychiatry’s version of the living will in which people can specify what sort of medical care they would like should they become mentally unwell and unable to exercise appropriate judgement. An intrinsic part of this might include a “Ulysses contract” — just as Ulysess instructed his crew to lash him to the mast of the his ship so that he could... (shrink)

Buddhism became established as a state religion in Korea during the sixth century, and was able to maintain that status with relatively little opposition throughout the Unified Silla and Koryô periods. However, at the end of the Koryô, the Buddhist establishment ended up in a serious confrontation with a rising Korean Neo Confucian polemical movement, a confrontation in which it would end up being the clear loser. The nature of the developing Neo Confucian polemic was twofold. The first aspect was (...) an outcry against the economic privileges and excessive government influence of the Buddhist church. The second was a philosophical/religious opposition to Buddhist doctrine and practice, which had developed out of the writings of the Sung Neo Confucian architects, most important of whom were the two Ch'eng brothers and Chu Hsi.

This article has the purpose of examining the commentation that Sung-ho Yi Ik and Da-san Jung Yak-yong developed of Sa-chil Debate (사칠논쟁) Which was a philosophical debate in Chosun Dynasty. Sa-chil Debate began from Toe-gye Yi Whang and Ko-bong Gi Dae-sung and soon as a result of Yul-gok Yi Yi and Woo-gae Sung Hon repeating the debate, It appeared as a kind of philosophical theme. After that, Yul-gok and Toe-gye's students formed a kind of school. They also made the debate (...) extended and the theory more sophisticated by criticizing a counterpart's argument on base of ideologizing their teacher's theory. About 200 years after Toe-gye died, Sung-ho Yi Ik was born and after about 250 years, Da-san Jung Yak-yong was born. Both they experienced a western naturalscience and a catholic theory as Silhak Scholars (실학자). Therefore their this kind of interpretation about Sung-li Debate must be offering a deeply interesting investigation to us. In conclusion, Sung-ho advocated Toe-gye's theory at all, adding more explanation to it and Da-san evaluated all of Toe-gye's and Yul-gok's theory to be right because their theories have a unique logicality of making a sense. Sung-ho stood on a Shilhak view point gave up a organic cosmology ofSung-li theory which has a continuity to cosmology and moral theory, arguing Sa-chil-Li bal-Yil-lo Theory (四七理發一路說) by understanding Sa-chil Debate based on only moral perspective. Even though Da-san also said Yang-si Theory (兩是論) that both their theories are all right, he argued that Toe-gye's theory is much more important in the aspect of moral practice owing to his religious opinion by a catholic affect. By the way, Sung-ho supplemented and explained Toe-gye's theory, but he had not a sufficient logic and was not objective because of his leaning into advocating Toe-gye's theory much further. Da-san had an advantage of evaluating both Toe-gye's and Yul-gok's theory to be all right, but came to argue an insufficient philosophy on account of its simplicity. (shrink)
