ObjectivesThis study examined the association between childhood adversity and cognitive impairment in later life and explored the potential moderation effect of gender and race.MethodsThe study sample included 15,133 participants of the Health and Retirement Study who had complete data on key study measures and were more than 50. The outcome variable is a dichotomous indicator of cognitive impairment as assessed by the Telephone Interview for Cognitive Status for self-respondents and the 16-item Informant Questionnaire on Cognitive Decline in the Elderly for (...) proxies. A total of six childhood adversity indicators included grade retention, parental substance abuse, physical abuse, trouble with the police, moving due to financial hardship, and receipt of help due to financial hardship in early life. The estimation of the association between childhood adversity and cognitive impairment involved Cox proportional hazards regression. Results: Grade retention had the largest effect on incident cognitive impairment, followed by physical abuse by a parent. The impact of grade retention was more detrimental to women than men. Parental substance abuse was associated with a lower risk of incident cognitive impairment for most racial groups, but this association was reversed in “non-Hispanic other” race, consisting mainly of Asians.DiscussionSome aspects of childhood adversity continue to harm cognitive functioning in later life, while some events may have the opposite effect, with evidence of heterogeneity across gender and race.

This study investigated whether ruminating on an intrusive thought before sleeping led to an increased likelihood of dreaming of threatening events. One hundred and forty-six participants were randomly assigned to a rumination condition and a control condition. Participants completed a dream diary upon waking. The result showed that presleep ruminating on an intrusive thought increased the frequency of both threatening dreams and negative emotions in dreams. In addition, dreams with threatening events were more emotional and negative than dreams without threatening (...) events. These results may support the threat simulation theory of dreaming. In addition, these results may give some insight into a mathematical model for the continuity hypothesis of dreaming. (shrink)

Labels provide a quick and effective solution to obtain people interesting content from large-scale social network information. The current interest label extraction method based on the subgraph stream proves the feasibility of the subgraph stream for user label extraction. However, it is extremely time-consuming for constructing subgraphs. As an effective mathematical method to deal with fuzzy and uncertain information, rough set-based representations for subgraph stream construction are capable of capturing the uncertainties of the social network. Therefore, we propose an effective (...) approach called RS_UNITE_SS, which is suitable for large-scale social network user interest label extraction. Specifically, we first propose the subgraph division algorithm to construct a subgraph stream by incorporating a rough set. Then, the algorithm for user real-time interest label extraction based on upper approximation is proposed by using sequentially characteristics of the subgraph. Empirically, we evaluate RS_UNITE_SS over real-world datasets, and experimental results demonstrate that our proposed approach is more computationally efficient than existing methods while achieving higher precision value and MRR value.

Improving the innovation ability of organizations is the focal point of management study. This paper puts forward that innovative self-efficacy and employees’ innovative behaviour are continuous mediating variables, and discusses the influence mechanism of employees’ involvement and open service innovation from the individual factor level. In this study, a sample of 103 employees from travel companies was used to examine the hypothesis. The results show that employee engagement is positively related to open service innovation. Innovative self-efficacy plays a completely intermediary (...) role between employee engagement and employee innovative behaviour; Creative self-efficacy and employees’ innovative behaviour play a continuous intermediary role between employees’ engagement and open service innovation. The results of this study will eventually help enterprises to carry out service innovation behaviour. (shrink)

: 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.

Background: We described the prevalence of anxiety and depression related to COVID-19 pandemic among different types of population and examined their potential risk factors.Methods: A cross-sectional survey was conducted to collect demographic characteristics, exposure histories, and many other concerns about COVID-19. The Zung's self-rating anxiety scale and self-rating depression scale, followed by a four-step multiple logistic regression analysis was performed to identify factors associated with mental health outcomes.Results: Out of 3,303 participants, the quarantined people, community workstation staffs-policemen-volunteers and general public (...) reported higher percentages of depression than the general medical staff. Moreover, the quarantined people also showed higher prevalence of anxiety than the general public and the general medical staff. The quarantined people had the highest risk of anxiety and depression, whereas the self-rated health was negatively associated with the risks of anxiety and depression. Younger age group showed higher risks of anxiety and depression. People who had exposure history or contact from Hubei province after December 1, 2019, had family or friends engaged in front-line health care work, had confirmed case nearby were all more likely to suffer from anxiety. Moreover, the negligence or overindulgence toward the epidemic information was associated with a higher risk of depression and anxiety.Conclusions: Our findings show that the CPV and quarantined people were most at-risk population. We have identified that the young people, people with exposure histories and negligence or overindulgence toward epidemic information are in grave need of attention. (shrink)

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)

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 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)

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)

Kuhn regards local incommensurability as an unavoidable result of changes in worldview, but his account fails to explain both historical cases in which rivals with different paradigms obtained consensus, and psychological experiments in which people with different cultural backgrounds accurately presented other points of view. Although the conditions required to generate local incommensurability were present in the dispute between Brewster and Herschel on light absorption, they succeeded in communicating. Ultimately Brewster understood his opponent's position, in the same way that subjects (...) in Barsalou's recent psychological experiments proved able to comprehend alien conceptual structures. Building upon recent cognitive theories of graded conceptual structures, I offer a new account of incommensurability, which accommodates these historical cases and psychological results. By correcting and extending Kuhn's account I show that local incommensurability may be a matter of degree. (shrink)

Problem and Project Based Learning (PBL) has been used as an educational philosophy and methodology in the construction of a student centered and contextualized learning environment. PBL is also regarded as an effective method in producing engineering graduates who can not only meet the needs of professional competences but are also prepared for new challenges in the globalized and technological context. However, can PBL be a solution to the challenge of a general lack of university students studying engineering and technology (...) in many countries? Gender and Diversity in a Problem and Project Based Learning Environment presents an ethnographical study on the learning experiences of engineering students in the PBL environment in Denmark, and it attempts to question the issue of diversity in engineering education via the exploration of which ways the PBL environment is friendly to diverse groups of learners such as women.

With the troubles of core losses and all-state confined to certain limitations which are the innate traits of permanent magnet synchronous motors, this article develops a command filtered adaptive backstepping approach to follow the track of PMSM’s desired rotor position. To begin with, the RBF neural network technique is utilized to get close to the uncharted nonlinear terms which existed in PMSM’s mathematical model. Meanwhile, an advanced adaptive command filter control methodology is constructed to avoid the computing explosion during the (...) process of backstepping design. Furthermore, to make sure that all the state variables are confined into certain ranges, we employed the barrier Lyapunov function at every step of the controllers construction. In addition, an error compensating mechanism is proposed to neutralize filtering errors and only one adaptive law is required. At last, simulation results bear out the superiority of the aforementioned control scheme. (shrink)

Many recent cognitive studies reveal that human cognition is inherently perceptual, sharing systems with perception at both the conceptual and the neural levels. This paper introduces Barsalou's theory of perceptual symbols and explores its implications for philosophy of science. If perceptual symbols lie in the heart of conceptual processing, the process of attribute selection during concept representation, which is critical for defining similarity and thus for comparing taxonomies, can no longer be determined solely by background beliefs. The analogous nature of (...) perceptual symbols and the spatial nature of intraconceptual relations impose new constraints on attribute selection. These constraints help people with different background beliefs select compatible attributes, which constitute a common "platform" for taxonomy comparison. (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)

How physicians can get better ratings and more page views in online healthcare communities is an important issue. Based on 38,457 physicians' profiles from a popular online healthcare community in China, we used Latent Dirichlet Allocation model, which is a common topic model, to analyze the non-English text to obtain more doctor's latent characteristics. We found five of the most frequently mentioned topics. In addition to the first topic, “research ability,” “foreign experience,” “committee position,” and “clinical experience” were included as (...) unstructured descriptions in the doctor's profile. Inferences about physician ratings and page views could be improved if these themes were set as characteristics of physicians. Specifically, in our findings, Physicians' mentions of their “research ability” and “foreign experience” had a significant positive impact on physician ratings. Surprisingly, physicians mentioning more “clinical experience” had a significant negative impact on physician ratings. Moreover, while descriptions about “foreign experience” and “committee position” had a significant positive impact on page views, physician mentions of “research ability” had a significant negative impact on page views. These results provide new insights into the ways in which online healthcare community managers or physicians create their personal online profiles. (shrink)

Through close reading of Jonathan Swift’s religious works and his novel, this paper traces his deepening critical attitudes towards religion. According to his writing time sequence, the targets of his ridicule become larger and larger, from Roman Catholic and Puritans, to the declining Christianity, and to all religions in general, which reflects his uncompromising stance as an Enlightener.

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.

From the end of 1973 to early 1974, silk books from the Han dynasty were unearthed from tomb no. 3 at Mawangdui in Changsha, Hunan. After reorganizing and piecing them together, there were a total of twenty-eight kinds of silk books, of which four are copies of ancient books that are no longer in existence.1 They are: Jing fa, Shi liu jing, Cheng, and Dao yun, with a total of more than eleven thousand characters. These books were written before the (...) book Lao Zi. To simplify the titles, we have temporarily named these four books Huangdi shu.2 Six works of notes and interpretation have been published up until now, collating and piecing the silk book Huangdi shu. There was warm discussion in academic circles as to the name and nature of this book, when and who copied and wrote it out, the content and ideology, and which school it belongs to. Research on these questions began in the 1980s. This article focuses on a brief review of local research. I will make a special introduction about the research abroad. (shrink)

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)

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.

When a widely reused ontology appears in a new version which is not compatible with older versions, the ontologies reusing it need to be updated accordingly. Ontobull has been developed to automatically update ontologies with new term IRI(s) and associated metadata to take account of such version changes. To use the Ontobull web interface a user is required to (i) upload one or more ontology OWL source files; (ii) input an ontology term IRI mapping; and (where needed) (iii) provide update (...) settings for ontology headers and XML namespace IDs. Using this information, the backend Ontobull Java program automatically updates the OWL ontology files with desired term IRIs and ontology metadata. The Ontobull subprogram BFOConvert supports the conversion of an ontology that imports a previous version of BFO. A use case is provided to demonstrate the features of Ontobull and BFOConvert.

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.

The approach of returning to the original and recovering nature is a typical characteristic of Chinese philosophy. It was founded by the Daoist School and followed by both Daoist and Confucian schools. The precondition of returning to the original and recovering nature is the stillness and goodness within nature integrated into a whole afterwards. Its implementation includes not only returning to the original root so as to achieve the philosophical aim but also restoration to the original nature after it is (...) injured by man’s physical nature and desire. The realization of human nature depends on the work making up for the loss of the original nature. Although there are different methods of realization concerning the return to the original nature, such as returning to the root, seeking the lost mind, extinguishing desire, being good at return, and the self-consciousness of intuitive knowledge, all of these aim at returning to the original nature of stillness and purity. The philosophical value consists in the unceasing pursuit of returning to the original nature. (shrink)

Histone post-translational modifications play important roles in transcriptional regulation. It is known that multiple histone modifications can act in a combinatorial manner. In this study, we investigated the effects of multiple histone modifications on expression levels of five gene categories in coding regions. The combinatorial patterns of modifications for the five gene categories were also studied in the regions. Our results indicated that the differences in the expression levels between any two gene categories were significant. There were some corresponding differences (...) in multiple histone modification levels among the five gene categories. Multiple histone modifications jointly impacted expression levels of every gene category. Four mutual combinations of histone modifications were found and analyzed. (shrink)

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)

ABSTRACT This paper draws upon transitivity and Appraisal within Systemic Functional Linguistics to study the traumatic discourse of Nanjing Massacre in Chinese Mainland’s and Japan’s history textbooks. Through corpus analysis, this research finds that the Chinese discourse mainly uses effective process, relational process, verbal process to construe Japan’s victimizering experience and China’s victimhood, and employs negative Affect, opposite values of Judgment, negative Appreciation, Expand, Raise and Sharpen to construct a critical voice for the Japanese army and a sympathic tone for (...) the Chinese. By contrast, the Japanese discourse largely uses pseudo-effective and middle processes, mental and existential processes to cover up Japan’s victimizering experience, and employs negative Judgment, positive Appreciation, Contract and Raise to construct an almost uncritical voice for the Japanese army and the massacre. The difference in the representation and evaluation of Nanjing Massacre results from the politics of official memories in both countries. As China endeavors to strengthen its patriotic education by using Nanjing Massacre as an ideological weapon for national solidarity, Japan expedites its nationalist historiography move to recreate its normal national image by marginalizing the massacre.

Coevolution spreading dynamics on complex networks is a hot topic, which attracts much attention in network science. This paper proposes a mathematical model to describe the two competing complex information spreading dynamics on multiplex networks. An individual can only accept one of the two pieces of information. A heterogeneous mean-field theory is developed to describe the spreading dynamics. We reveal different regions through Monte Carlo simulations of the competing complex information spreading dynamics: no global information, one information dominant, and two (...) information coexistence. We finally find that the heterogeneity of the multiplex networks’ degree distributions does not qualitatively affect the results. (shrink)
