In this work, a virtual submerged floating operational system based on parallel and serial robotic platforms is proposed. The primary aim behind its development lies in carrying out simulated underwater manipulation experiments in an easier and safer way. This VSFOS is consisted of a six-degree-of-freedom parallel platform, an ABB serial manipulator, an inertial sensor, and a real-time industrial computer. The 6-DOF platform is used to simulate the movement of an underwater vehicle, whose attitude is measured by the inertial sensor. The (...) ABB manipulator, controlled by the real-time industrial computer, works as an operational tool to perform underwater manipulation tasks. In the control system architecture, software is developed to receive the data collected by the inertial sensor, to communicate and send instructions. Furthermore, the real-time status of the manipulator is displayed in this software. To validate the proposed system, two experiments have been conducted to test its performance. In the first experiment, the test is carried out to check the communication function of VSFOS, while in the second one, the manipulator is intended to follow the movement of the parallel platform and perform simulated operational task in the space. The obtained results from these two experiments show clearly the effectiveness and the performance of the proposed VSFOS. (shrink)

In this paper, the method of mutual information is used to study the economic dependence among the provinces in Chinaʼs Eastern Coastal Economic Belt from 2015 to 2020, and the core structure of the dependence is depicted. The results show that, first of all, there is a wide range of economic dependence among the provinces in the Eastern Coastal Economic Belt, and the dependence changes with the different states of economic development. Secondly, the phenomenon of geographical clustering is not obvious. (...) Most provinces maintain a strong economic dependence relationship with the economically developed provinces, and this dependence relationship is relatively stable, while the economically underdeveloped provinces are often on the edge of the dependence structure. Finally, the economically developed provinces maintain strong economic dependence with each other, such as Jiangsu, Shandong, and Zhejiang, and Beijing, Guangdong, and Shanghai. However, the former three provinces are more in the core position of this structure, that is, the other provinces maintain the stronger dependence relationship with these three provinces. (shrink)

In a previous article we have shown that Kuhn's theory of concepts is independently supported by recent research in cognitive psychology. In this paper we propose a cognitive re-reading of Kuhn's cyclical model of scientific revolutions: all of the important features of the model may now be seen as consequences of a more fundamental account of the nature of concepts and their dynamics. We begin by examining incommensurability, the central theme of Kuhn's theory of scientific revolutions, according to two different (...) cognitive models of concept representation. We provide new support for Kuhn 's mature views that incommensurability can be caused by changes in only a few concepts, that even incommensurable conceptual systems can be rationally compared, and that scientific change of the most radical sort—the type labeled revolutionary in earlier studies—does not have to occur holistically and abruptly, but can be achieved by a historically more plausible accumulation of smaller changes. We go on to suggest that the parallel accounts of concepts found in Kuhn and in cognitive science lead to a new understanding of the nature of normal science, of the transition from normal science to crisis, and of scientific revolutions. The same account enables us to understand how scientific communities split to create groups supporting new paradigms, and to resolve various outstanding problems. In particular, we can identify the kind of change needed to create a revolution rather precisely. This new analysis also suggests reasons for the unidirectionality of scientific change. (shrink)

To correct the misconception that incommensurability implies incomparability, Kuhn lately develops a new interpretation of incommensurability. This includes a linguistic theory of scientific revolutions (the theory of kinds), a cognitive exploration of the language learning process (the analogy of bilingualism), and an epistemological discussion on the rationality of scientific development (the evolutionary epistemology). My focus in this paper is to review Kuhn's effort in eliminating relativism, highlighting both the insights and the difficulties of his new version of incommensurability . Finally (...) I suggest that some of Kuhn's difficulties can be overcome by adopting a concept of rationality that filly appreciates the important role of instruments in the development of science. (shrink)

In this paper we examine the pattern of conceptual change during scientific revolutions by using methods from cognitive psychology. We show that the changes characteristic of scientific revolutions, especially taxonomic changes, can occur in a continuous manner. Using the frame model of concept representation to capture structural relations within concepts and the direct links between concept and taxonomy, we develop an account of conceptual change in science that more adequately reflects the current understanding that episodes like the Copernican revolution are (...) not always abrupt. When concepts are represented by frames, the transformation from one taxonomy to another can be achieved in a piecemeal fashion not preconditioned by a crisis stage, and a new taxonomy can arise naturally out of the old frame instead of emerging separately from the existing conceptual system. This cognitive mechanism of continuous change demonstrates the constructive roles of anomaly and incommensurability in promoting the progress of science. (shrink)

Kirk Lougheed argues that active euthanasia (here ‘euthanasia’) is impermissible for people who are extremely sick and cannot exercise their vital forcei because (1) exercising vital force does not require volition but only being an object of caring relationships and (2) African philosophy entails other-regarding deontological duties to stay alive.1 In this commentary, we point out an implication of Lougheed’s view that is morally problematic and offer a revision that avoids this implication. We also argue for an additional advantage of (...) this revision. Lougheed’s view implies that a person who is the object of very few relationships has a much weaker duty to stay alive than a person who is well-loved and the object of many relationships. This is because he seems to think that duties to stay alive are derived entirely from one’s relationship with other people. While he is clear that a person, even if terminally ill or permanently unconscious, has a duty to stay alive so that they could remain the object of harmonious relationships, he is silent on whether duties to stay alive could be grounded in reasons that have to do with oneself. Plausibly, on this view, the strength of one’s duty to stay alive depends solely …. (shrink)

This paper offers a solution to a problem in Herschel studies by drawing on the dynamic frame model for concept representation offered by cognitive psychology. Applying the frame model to represent the conceptual frameworks of the particle and wave theories, this paper shows that discontinuity between the particle and wave frameworks consists mainly in the transition from a particle notion ‘side’ to a wave notion ‘phase difference’. By illustrating intraconceptual relations within concepts, the frame representations reveal the ontological differences between (...) these two concepts. ‘Side’ is an object concept built on spatial relations, but ‘phase difference’ is an event concept built on temporal relations. The conceptual analyses display a possible cognitive source of Herschel’s misconception of polarization. Limited by his experimental works and his philosophical beliefs, Herschel comprehended polarization solely in terms of spatial relations, which prevented him from replacing the object concept ‘side’ with the event concept ‘phase difference’, and eventually resulted in his failure to understand the wave account of polarization.Author Keywords: Herschel; Polarization; Object concept; Event concept; Frame; Cognitive psychology.

In this article I explain why scientists cannot always resolve their disagreements about experiments even if they do not hold conflicting theoretical assumptions, and how incommensurability in experiments can occur even if experiments are not deeply encumbered by theoretical assumptions. On the basis of recent discoveries in cognitive psychology and an extended analysis of a historical case, I explore a cognitive mechanism that may generate incommensurability in experiment appraisal. I find that, because of the involvement of goal-derived categories, incommensurability in (...) experiments may result from the conflict of goals that scientists pursue in their researches, from the differences of goal-derived classification schemata that they employ in analyzing experiments, and from discrepancies between skills that they have developed in their practices. This account differs from the conventional interpretation of Kuhn’s thesis, which attributes the cause of incommensurability solely to theoretical differences. In the conclusion, I further discuss the implications of this new account of incommensurability for both philosophical and historical studies of science. (shrink)

The overwhelming motif of nineteenth century anti-Semitic discourse is the metaphor of the Jew as a ghost. In all cultures, the ghost represents the antithesis of what is categorically human: it represents the other par excellence. By using the heuristic of the ghost to interpret how Enlightenment discourse has dealt with the other, this article will argue that the Enlightenment model of the self and its relation to others was a contributing factor to Modern Racism. Enlightenment discourse on subjectivity finds (...) its counterpart in Confucian notions of subjectivity. By looking at how ghosts are understood within Confucian discourse and how they are evoked in popular literature, I argue that Confucian philosophy’s model of subjectivity contributed to the success of the Chinese empire’s assimilation project.

This paper revisits two fundamental issues in question semantics—what does a question mean, and how is this meaning compositionally derived? Drawing on observations with the distribution of wh-words in questions and free relatives as well as quantificational variability effects in question-embeddings, I argue that the nominal meanings of short answers must be derivable from question denotations, which therefore calls for a categorial approach to defining questions, including embedded questions. I provide a novel hybrid categorial approach to compose questions. This approach (...) overcomes the problems with traditional categorial approaches in defining bare wh-indefinites, composing multi-wh questions, and accounting for coordinations of questions.

Through a key passage (Xici 2.2) from the Book of Changes, this paper shows that Ernst Cassirer’s philosophy of symbolic forms shares similarities with the canonical account of symbolic formation in the Chinese tradition: the genesis of xiang (象), often translated as image or symbol. xiang became identified with the origins of culture/civilisation itself. In both cases, the world is understood as primordially (phenomenologically) meaningful; the expressiveness of the world requires a human subject to consummate it in a (...) symbol, whilst the symbol in turn gives us access to higher orders of meaning. It is the self-conscious creation of the symbol that then allows for the higher forms of culture. For both the Xici and Cassirer, symbols and the symbolic consciousness that comes with it is the pre-condition for the freedom, ethics and the cultivation of agency. As for both the Xici and Cassirer, it is human agency that creates these symbols, it will be argued that the Xici is making a Cassirerian argument about the (ethical) relationship between human agency, symbols and ethics/freedom.

Many empirical studies have been conducted to investigate self-regulated learning in the Western countries. Less well investigated is the SRL in the Chinese Mainland students and how it affects their academic achievement. On the basis of PISA 2009, this paper is aimed at exploring the SRL of 15-year-old Shanghai students, as measured by cognitive strategy, metacognition, and motivational belief. In the aspect of SRL nature, the results reveal that 15-year-old students in Shanghai use elaboration strategy frequently and seldom use memorization (...) strategy, and that they have high metacognition in understanding, remembering, and summarizing but have low control strategy, and that their enjoyment of reading is relatively high. In the aspect of SRL’s consequence for reading literacy, findings from multilevel linear regression corroborate previous evidence from the Western countries about the effect of SRL on academic achievement. Specifically, elaboration strategy, metacognition in understanding and remembering, metacognition in summarizing, control strategy, and enjoyment of reading are conducive to students’ reading literacy, while memorization strategy exerts a significantly negative effect on reading literacy. The findings could be useful in helping us to gain a better understanding of Shanghai students’ SRL. (shrink)

In this paper I examine a cognitive mechanism of incommensurability. Using the frame model of concept representation to capture structural relations within concepts, I reveal an ontological difference between object and event concepts: the former are spatial but the latter temporal. Experiments from cognitive sciences further demonstrate that the mind treats object and event concepts differently. Thus, incommensurability can occur in conceptual change across different ontological categories. I use a historical case to illustrate how the ontological difference between an object (...) and an event concept actually caused incommensurability in the context of nineteenth‐century optics. The cognitive and historical analyses indicate that incommensurability can be a local phenomenon and does not necessarily imply incomparability. (shrink)

In most cases, a wh-question calls for an answer that names an entity in the set denoted by the extension of the wh-complement. However, evidence from questions with necessity modals and questions with collective predicates argues that sometimes a wh-question must be interpreted with a higher-order reading, in which this question calls for an answer that names a generalized quantifier. This paper investigates the distribution and compositional derivation of higher-order readings of wh-questions. First, I argue that the generalized quantifiers that (...) can serve as semantic answers to wh-questions must be homogeneously positive. Next, on the distribution of higher-order readings, I observe that questions in which the wh-complement is singular-marked or numeral-modified can be answered by elided disjunctions but not by conjunctions. I further present two ways to account for this disjunction–conjunction asymmetry. In the uniform account, these questions admit disjunctions because disjunctions may satisfy the atomicity requirement of singular-marking and the cardinality requirement of numeral modification. In the reconstruction account, the wh-complement is syntactically reconstructed, which gives rise to local uniqueness and yields a contradiction for conjunctive answers. (shrink)

IntroductionDuring the COVID-19 outbreak, many citizens were asked to stay at home in self-quarantine, which can pose a significant challenge with respect to remaining physically active and maintaining mental health. This study aimed to evaluate the prevalence of inadequate physical activity, anxiety, and depression and to explore the relationship of physical activity with anxiety and depression symptoms among Chinese college students during quarantine.MethodUsing a web-based cross-sectional survey, we collected data from 1,396 Chinese college students. Anxiety and depression were assessed with (...) the Self-Rating Anxiety Scale and the Self-Rating Depression Scale, respectively. The data on physical activity were collected by types of physical activity and the International Physical Activity Questionnaire.ResultsDuring the COVID-19 outbreak, about 52.3% of Chinese college students had inadequate physical activity. The rates of anxiety and depression symptoms were 31.0 and 41.8%, respectively. A high level of physical activity was significantly closely associated with low anxiety, while a moderate, or high level of physical activity was significantly closely associated with reduced depression after adjusting confounding demographic factors. Moreover, specific types of physical activity, such as stretching and resistance training, were negatively correlated with both anxiety and depression; doing household chores was negatively correlated with depression.ConclusionOur findings highlight specific levels and types of home-based physical activities that need to be taken into consideration to protect the mental health of college students during the COVID-19 epidemic.

I propose a new perspective on the study of scientific revolutions. This is a transformation from an object-only perspective to an ontological perspective that properly treats objects and processes as distinct kinds. I begin my analysis by identifying an object bias in the study of scientific revolutions, where it takes the form of representing scientific revolutions as changes in classification of physical objects. I further explore the origins of this object bias. Findings from developmental psychology indicate that children cannot distinguish (...) processes from objects until the age of 7, but they have already developed a core system of object knowledge as early as 4 months of age. The persistence of this core system is responsible for the object bias among mature adults, i.e., the tendency to apply knowledge of physical objects to temporal processes. In light of the distinction between physical objects and temporal processes, I redraw the picture of the Copernican revolution. Rather than seeing it as a taxonomic shift from a geocentric to a heliocentric cosmology, we should understand it as a transformation from a conceptual system that was built around an object concept to one that was built around a process concept.

This discussion seeks to highlight the ability of poetry to combat loneliness, a growing public health problem with significant negative health outcomes that potentially impact millions of Americans. We argue that poetry can play a very relevant role and have an impact in medicine. Through a brief literature review of previous studies on poetry in medicine, we demonstrate that poetry can not only combat loneliness but can also play important roles in helping patients, physicians, and other healthcare professionals/providers. Because of (...) the COVID-19 pandemic, we believe now is the perfect opportunity to utilize poetry because the benefits can be experienced even in solitude, which is why this is such a timely and pertinent issue today.

This paper argues that the ‘processual holism’ of Chinese metaphysics explains its characteristic attitude towards non-humans such as animals and demons. As all things are constantly in process and form a continuum, it follows that ontological distinctions between ‘species’ become impossible to delimit. The distinctions one makes are instead understood as perspectival and provisional. These metaphysical assumptions explain the lack of interest in the Chinese tradition for classifying the distinctions between humans and non-human. We see many examples of the different (...) schools of philosophy espousing the view that the distinction between humans and non-humans is tenuous, precarious and subject to change. A key implication that follows is that the Chinese worldview saw no ontological distinction between those considered as ‘Chinese’ and as ‘non-Chinese.’ The unavailability of ontological distinction as an explanation for the existence of difference means that phenomena that are perceived as anomalous, such as ghosts and spirits, are attributed to the perspective of the human agent; anomaly/difference is not understood as ontological.

: This paper offers a preliminary analysis of conceptual change between event concepts. It begins with a brief review of the major findings of cognitive studies on event knowledge. The script model proposed by Schank and Abelson was the first attempt to represent event knowledge. Subsequent cognitive studies indicated that event knowledge is organized in the form of dimensional organizations in which temporally successive actions are related causally. This paper proposes a frame representation to capture and outline the internal structure (...) of event concepts, in particular, their causal connections. The frame representation offers an effective method to analyze the relations between event concepts, and to expose the unique cognitive mechanisms behind conceptual change involved event concepts. Finally this paper shows that the frame representation of event concepts is instrumental to understanding an important historical episode of conceptual change in the context of nineteenth-century optics.

Lysine acetylation has been shown to occur in many protein targets, including core histones, about 40 transcription factors and over 30 other proteins. This modification is reversible in vivo, with its specificity and level being largely controlled by signal‐dependent association of substrates with acetyltransferases and deacetylases. Like other covalent modifications, lysine acetylation exerts its effects through “loss‐of‐function” and “gain‐of‐function” mechanisms. Among the latter, lysine acetylation generates specific docking sites for bromodomain proteins. For example, bromodomains of Gcn5, PCAF, TAF1 and CBP (...) are able to recognize acetyllysine residues in histones, HIV Tat, p53, c‐Myb or MyoD. In addition to the acetyllysine moiety, the flanking sequences also contribute to efficient recognition. The relationship between acetyllysine and bromodomains is reminiscent of the specific recognition of phosphorylated residues by phospho‐specific binding modules such as SH2 domains and 14‐3‐3 proteins. Therefore, lysine acetylation forges a novel signaling partnership with bromodomains to govern the temporal and spatial regulation of protein functions in vivo.

This article argues that Cassirer’s thinking about the relationship between the different symbolic forms is best elucidated via the paradigm of “organic harmony.” Although Cassirer did not use the term himself, the harmonious cooperation between the parts found in the organic world provided him with a welcome alternative to traditional accounts of order (i.e., identity or hierarchy). This article gives three examples of “organic harmony” from which Cassirer drew inspiration: Goethe’s idealistic morphology, Wilhelm von Humboldt’s account of language, and Herder’s (...) account of history. Through “organic harmony” we can make better sense of and better articulate the pluralism of Cassirer’s PSF. Finally, this article shows how the motif of organic harmony is the normative moment in Cassirer’s own challenge to twentieth-century fascism and argues that the Cassirerian emphasis on finding a coherence which does justice to the uniqueness of particulars—harmony—is an ethical injunction relevant for our times.

According to the desire-satisfaction theory of well-being, your life goes well to the extent that your desires are satisfied. This theory faces the problem of prudential neutrality: it apparently cannot avoid saying that, from the point of view of prudence or self-interest, you ought to be neutral between satisfying an existing desire of yours and replacing it with an equally strong desire and satisfying the new desire. It also faces the problem of remote desires: it regards as directly relevant to (...) your well-being even desires whose objects are intuitively too irrelevant to (or ‘remote’ from) your life to affect your welfare. In this article, I argue that desire theorists can answer both objections by appealing to hidden desires – ones that it is psychologically realistic to attribute to the agents in the cases on which the two problems are based, even though they are not mentioned in descriptions of those cases.

I propose a new perspective with which to understand scientific revolutions. This is a conversion from an object-only perspective to one that properly treats object and process concepts as distinct kinds. I begin with a re-examination of the Copernican revolution. Recent findings from the history of astronomy suggest that the Copernican revolution was a move from a conceptual framework built around an object concept to one built around a process concept. Drawing from studies in the cognitive sciences, I then show (...) that process concepts are independent of object concepts, grounded in specific regions of the brain and involving unique representational mechanisms. There are cognitive obstacles to the transformation from object to process concepts, and an object bias—a tendency to treat processes as objects—makes this kind of conceptual change difficult. Consequently, transformation from object to process concepts is disruptive and revolutionary. Finally, I explore the implications of this new perspective on scientific revolutions for both the history and philosophy of science.Keywords: Scientific revolutions; Process concepts; Object concepts; Object bias; Copernican revolution.

The student management work model in colleges and universities is an effective plan for college student management, but the traditional college student management work is not very good in terms of student psychology, resulting in negative attitudes such as low learning desire, low learning efficiency, and inactive learning. In recent years, with the development of artificial intelligence technologies such as sentiment analysis and incentive theory, emotional management and incentive theory have been applied to the management of college students. The emotional (...) management and incentive model is a way to help college students get rid of psychological obstacles and guide students to establish positive and correct values by predict and analyze the psychological state of college students through language emotion recognition and BP neural network. This paper compares the college student management work model based on emotional management and incentives with the traditional college management work mode through experiments. The results show that the students’ learning enthusiasm is better than the traditional college student management work mode based on emotional management and incentives. The student management work model in colleges and universities is 15.8% better, and the students’ grades have improved by 12.5%; the college student management work model based on emotional management and incentives also has a positive role in helping students’ mental health. The way of emotional management and motivation can make better use of college students’ psychology to effectively manage students and guide students to develop in a good direction. (shrink)

Previous studies of the history of optics reveal that the confrontation between the emission theory of light and the undulatory theory of light in Britain occupied a considerable period during the early nineteenth century. After the majority of British physicists accepted the undulatory theory in the mid-1830s a few emissionists in Britain did not immediately surrender. They continued to fight a rear-guard action against the undulatory theory, hoping that someday they could reinstate their theory.’ The longevity of the confrontation between (...) the emission and the undulatory theory is consistent with recent philosophical and sociological accounts of science, which expect scientific controversy to last a considerable time. Lakatos’s philosophical account, for example, holds that a degenerating theory does not disappear immediately and may revive at any time through a burst of ‘heuristic power’. But this account only allows one universal standard-the verification of excess empirical content-as the basis for both the generation and the closure of scientific controversies.’ On the other hand, sociological accounts such as actor-network theory have also done much to dispel the impression that rapid closure is inevitable in scientific controversies. But perhaps they risk a new orthodoxy: that controversy itself is inevitable. (shrink)

This paper concentrates on a debate over dispersion in the second half of the 1830s, in which both sides utilized the same set of experimental data to test a proposed wave account of dispersion, but could not agree on how these data should be used. The conflict regarding experimental data was caused by differences in instruments. In the debate, optical instruments in many ways functioned like paradigms, shaping scientists' opinions. Instruments also led the debate into an impasse, because no apparatus (...) was available for the necessary experimental replication. Because of unreconcilable differences regarding experimental evidence, the wave theory's failure in explaining dispersion did not become an obstacle to its acceptance. (shrink)

_Wh_-questions with the modal verb _can_ admit both mention-some (MS) and mention-all (MA) answers. This paper argues that we should treat MS as a grammatical phenomenon, primarily determined by the grammar of the _wh_-interrogative. I assume that MS and MA answers can be modeled using the same definition of answerhood (Fox in Mention-some interpretations, MIT seminar, 2013 ) and attribute the MS/MA ambiguity to structural variations within the question nucleus. The variations are: (i) the scope ambiguity of the higher-order _wh_-trace (...) and (ii) the absence/presence of an anti-exhaustification operator. However, treating MS answers as complete answers in this way contradicts the widely adopted analysis of uniqueness effects in questions of Dayal (Locality in _wh_ quantification: Questions and relative clauses in Hindi, 1996 ), according to which the uniqueness effects of singular _which_-phrases arise from an exhaustivity presupposition, namely that a question must have a unique exhaustive true answer. To solve this dilemma, I propose that question interpretations presuppose Relativized Exhaustivity: roughly, the exhaustivity in questions is evaluated relative to the accessible worlds as opposed to the anchor/utterance world. Relativized Exhaustivity preserves the merits of Dayal’s exhaustivity presupposition while permitting MS; moreover, it explains the local-uniqueness effects in modalized singular _wh_-questions.
