Presently, the State Grid Corporation of China has accumulated a large amount of maintenance records for power primary equipment. Unfortunately, most of these records are unstructured data which lead to difficultly analyze and utilize them. The emergence of natural language processing technology and deep learning methods provide a solution for unstructured text data. This paper proposes a progressive multitype feature fusion model to recognize Chinese named entity of unstructured maintenance records for power primary equipment. Firstly, the textual characteristics and word (...) separation difficulties of maintenance records are analyzed, then 7 main entity categories of power technical terms from unstructured maintenance records are chosen, and 3452 maintenance records are labeled by these categories, which is so called EPE-MR training dataset. Secondly, the standard test reports, standard maintenance, and fault analysis reports for three types of power primary equipment are employed as corpus to train character embedding in order to obtain certain words representation ability of maintenance records. After that, progressive multilevel radicals feature extraction module is designed to get detailed and fine semantic information in a hierarchical manner. Further, radicals feature representation and character embedding are concatenated and sent to BiLSTM module to extract contextual information in order to improve Chinese entity recognition ability. Moreover, CRF is introduced to handle the dependencies among prediction labels and to output the optimal prediction sequence, which can easily obtain structured data of maintenance records. Finally, comparative experiments on public MSRA dataset, China People’s Daily corpus, and EPE-MR dataset are implemented, respectively, which show the effectiveness of the proposed method. (shrink)

Counterfeiting is common in many industries. For the authenticity of online channel products and to combat counterfeiting, many companies have begun to use blockchain technology to trace product information. This paper investigates a dual-channel supply chain consisting of one manufacturer and one retailer, in which the manufacturer sells its standard products through the retailer and adopts blockchain technology to launch the online channel to sell the traceable products. A Stackelberg game is developed to depict the pricing decision and channel strategy (...) choice for the manufacturer. It shows that both the manufacturer and the retailer can benefit from blockchain adoption. And the longer it takes for product traceability, the lower the price of online traceable products. It is beneficial for the manufacturer when consumers in the market are less concerned about information transparency. For consumer sensitivity, as consumers’ acceptance of direct sales channels increases, the selling prices of online traceable products have risen. Furthermore, as the traceability time-sensitivity coefficient increases, the sales price of the traceable products decreases, and the retail price of offline standard products rises. The conclusion of this paper has a certain guiding role for the dominant manufacturers in choosing whether to apply blockchain technology to improve the demand for traceable products. (shrink)

The time-lag argument seems to put some pressure on naïve realism to agree that seeing must happen simultaneously with what is seen; meanwhile, a wide-accepted empirical fact suggests that light takes time to transmit from objects at a distance to perceivers—which implies what is seen happened before seeing, and, accordingly, naïve realism must be false. In this paper, I will, first of all, show that the time-lag argument has in fact involves a misunderstanding concept of simultaneity: according to Special Relativity, (...) simultaneity is a matter of convention rather than a matter of fact, so, in principle, we can stipulate a perceptual conception of simultaneity, according to which what is seen is simultaneous with seeing. Secondly, the generalized time-lag argument has a mistaken view on the perceived events and perceiving; it has a doubtful assumption that these events are momentary in the mathematical sense. Such idealization is the main reason why we have the intuition that the time-lag effect of perceiving is in conflict with our ordinary perceptual experiences. Finally, I argue that the naïve realist account of the perceptual relation is a nontemporal constitutive relation; and hence naïve realism is compatible with the claim that we can perceive things as they were, and it should not be weakened by the time-lag argument.

The argument from appearance for the content view or intentionalism attracts a lot of attention recently. In my paper, I follow Charles Travis to argue against the key premise that representational content can be ‘read off’ from a certain way that a thing looks to a subject. My arguments are built upon Travis’s original objection and a reinterpretation of Rodrick Chisholm’s comparative and noncomparative uses of appearance words. Byrne, Schellenberg and others interpret Travis’ ‘visual looks’ as Chisholm’s comparative use, and (...) appeal to the noncomparative use as an alternative to avoid Travis’s objection. I demonstrate that they misunderstand both Chisholm and Travis. Both the comparative use and the noncomparative use are semantic notions, while ‘visual looks’ is a metaphysical one. Although Chisholm’s appearance objectivism –– that appearance expressions attribute appearances to ordinary objects –– is close to ‘visual looks’, appearance objectivism is not exceptional to the noncomparative use as Byrne interprets. In the end, I also show that Byrnean’s conception of distinctive visual gestalt cannot exclude contrary representational contents, because a distinctive visual gestalt can be shared by different kinds of things. Besides, Byrne and others do not explain why a distinctive visual gestalt should be presented as ‘being instantiated’. Therefore, I conclude that representational content cannot be read off from a certain way that a thing looks to a subject; the argument from appearance thus fails. (shrink)

ObjectivesAimed to analyze the mediating effect of executive function between physical activity level and trait anxiety in college students.MethodsThe International Physical Activity Questionnaire, State-Trait Anxiety Inventory, Stroop task, 1-back task, and More-odd shifting task were used to analyze 248 college students.ResultsTrait anxiety were significantly correlated with shifting function (r = 0.182, P = 0.004) and inhibition function (r = 0.163, P = 0.010) and not with working memory (r = 0.056, P = 0.385). Vigorous physical activity (VPA) was most highly (...) correlated with inhibition function (Beta = −0.144, P = 0.024) and working memory (Beta = −0.208, P = 0.001), and light physical activity (LPA) was most highly correlated with shifting function (Beta = −0.211, P = 0.001). Physical activity had a 72.31% association with trait anxiety (B = −0.195), with 11.79% mediated by inhibition function (B = −0.023) and 15.90% by shifting function (B = −0.031).ConclusionCollege students' physical activity promotes both inhibition and shifting functions, which in turn affect trait anxiety. VPA had a direct effect, while the effect of moderate physical activity (MPA) and LPA was completely mediated exclusively through executive functions, and the mediating effect of shifting function was the highest. It is recommended that college workers should motivate students with high trait anxiety to engage in more VPA and pay attention to changes in their inhibition and shifting functions. (shrink)

The article presents an analysis of the activities of formal and informal art associations in the space of contemporary art in Russia and China. The two countries actively cooperate in the field of art, including at the institutional level, which actualizes the appeal to the work of existing creative unions. The object of attention in the framework of the study is the modern art associations of the two countries, and the subject is the relationship between the structure and activities of (...) official and informal art associations of China and Russia. The aim is to analyze the features of the activity of art associations in the conditions of the modern art space of their countries. The analysis of the state and directions of development of both official structures and informal art groups is carried out. The former in both Russia and China, as a rule, are the continuers of the traditions of the former structures, but the original function of the guide of the political course of the leadership of the countries in them remained at different levels, mostly decreasing. The latter are communities of artists who unite by creative interests or around a common exhibition space for them, in particular galleries. Moreover, both forms successfully exist in both states, reflecting the trends of artistic life and at the same time influencing it. (shrink)

One crucial premise in the argument from illusion is the Phenomenal Principle. It states that if there sensibly appears to be something that possesses a sensible quality, then there is something of which the subject is aware that has that sensible quality. The principle thus enables the inference from a mere appearance to an existence (usually a mental one). In the argument from appearance, a similar move is taken by some philosophers—they infer a content from a mere appearance. There are (...) two kinds of defences for the Phenomenal Principle in the literature, namely, the epistemological one (e.g. H.H. Price) and the semantic one (e.g. Frank Jackson). I argue that neither consolidates the Phenomenal Principle. I particularly demonstrate that the appearance verb in premise 1 of the argument from illusion is not used in the phenomenal sense as it is used in the Phenomenal Principle, which renders the argument essentially invalid. To avoid invalidity, the proponents either give up the phenomenal use, which makes the argument unable to serve its original purpose, i.e. inferring an unusual existence, or they insist on the phenomenal use in all premises of the argument, which will trivialise the argument. I also demonstrate that a similar objection applies to the argument from appearance. (shrink)

This study applied an artifact-centric view to investigate the consequences of enterprise social media usage. It investigates how enterprise social media usage influences employee creativity. A moderated mediation model is developed based on social exchange theory. The empirical sample of 238 employees is used to test the proposed model. Results of the empirical analysis performed using PROCESS macro of SPSS indicate that enterprise social media usage positively impacts employee creativity via the mediating mechanisms. Furthermore, social media usage frequency negatively moderates (...) this impact of enterprise social media usage on employee creativity via leader-member exchange. Interestingly, the empirical analysis reveals that the impact of enterprise social media usage frequency strengthens the indirect effect that enterprise social media usage has on employee creativity via perceived support for innovation.

This paper aims at offering a new disjunctivist solution – anomalous disjunctivism – to the screening-off problem. Anomalous disjunctivism focuses on the necessary causal conditions for perception and hallucination. It argues that the proximate cause is contingent on causing a particular kind of sensory experience that can either be perceptual or hallucinatory. It further shows that the perceived thing is a necessary causal condition for perceptual experience and the failure of perception is a necessary causal condition for the hallucinatory counterpart. (...) It is the case that any account of a hallucinatory experience relies on the nature of hallucination, and, therefore, the anti-naïve realist has to agree that the necessary causal condition matters. As a consequence, whatever account we take for a hallucination, it need not apply to its perceptual counterpart. The screening-off problem, thereby, is dissolved. (shrink)

The Conception of practice of Marx philosophy ended practical philosophy and started philosophy practice. Marx didn’t establish practical philosophy but enriched philosophy practice in the objectivity activity of human sensibility. By the objectivity activity of human sensibility in society, history and world wasphilosophy politicized and politics philosophized, which we muss face, when we think about the conception of practice of Marx philosophy and which is inevitable, when we talk about the social practice of contemporary globe.

The recent coronavirus disease 2019 pandemic pushed almost all institutions to adopt online and virtual education. The uncertainty of this situation produced various questions that perplexed educationists regarding what implications the pandemic would have on educational institutions, especially regarding how the switch to online education would impact the behavior and performance of students. The vast importance of this matter attracted the attention of researchers and served as the motivation for this research, which aims to resolve this confusion by studying the (...) use of mobile learning among students for educational purposes during the COVID-19 period. This study also examines how this situation has affected student learning behavior and performance in the higher education setting. This research is based on collaborative learning theory, sociocultural learning theory, and ML theory. This quantitative research employed the convenient sampling technique to collect data through structured questionnaires distributed to 396 students of higher education institutions who carry a mobile device. This study used descriptive and inferential statistics to make the data more meaningful. Structural equation modeling with AMOS software was used for hypothesis testing. The results showed that ML was a significant and positive predictor of SP and LB. Moreover, student LB partially mediated the relationship between ML and SP. The findings suggest that the academic performance of students can be enhanced by building a ML environment that aligns with the LB of students. Nevertheless, content suitable for ML must be developed, and future research should be conducted on this topic. (shrink)

Chemotherapy is an important therapeutic approach for cancer treatment. However, drug resistance is an obstacle that often impairs the successful use of chemotherapies. Therefore, overcoming drug resistance would lead to better therapeutic outcomes for cancer patients. Recently, studies by our own and other groups have demonstrated that there is an intimate correlation between the loss of the F‐box and WD repeat domain‐containing 7 (FBW7) tumor suppressor and the incurring drug resistance. While loss of FBW7 sensitizes cancer cells to certain drugs, (...) FBW7‐/‐ cells are more resistant to other types of chemotherapies. FBW7 exerts its tumor suppressor function by promoting the degradation of various oncoproteins that regulate many cellular processes, including cell cycle progression, cellular metabolism, differentiation, and apoptosis. Since loss of the FBW7 tumor suppressor is linked to drug resistance, FBW7 may represent a novel therapeutic target to increase drug sensitivity of cancer cells to conventional chemotherapeutics. This paper thus focuses on the new functional aspects of FBW7 in drug resistance. (shrink)

This article describes a representation-based framework of distributed cognition. This framework considers distributed cognition as a cognitive system whose structures and processes are distributed between internal and external representations, across a group of individuals, and across space and time. The major issue for distributed research, under this framework, are the distribution, transformation, and propagation of information across the components of the distributed cognitive system and how they affect the performance of the system as a whole. To demonstrate the value of (...) this representation-based approach, the framework was used to describe and explain an important, challenging, and controversial issue — the concept of affordance.

Previous studies on the effects of emotional context on memory for centrally presented neutral items have obtained inconsistent results. And in most of those studies subjects were asked to either make a connection between the item and the context at study or retrieve both the item and the context. When no response for the contexts is required, how emotional contexts influence memory for neutral items is still unclear. Thus, the present study attempted to investigate the influences of four types of (...) emotional picture contexts on recognition memory of neutral words using both behavioral and event-related potential (ERP) measurements. During study, words were superimposed centrally onto emotional contexts, and subjects were asked to just remember the words. During test, both studied and new words were presented without the emotional contexts and subjects had to make “old/new” judgments for those words. The results revealed that, compared with the neutral context, the negative contexts and positive high-arousing context impaired recognition of words. ERP results at encoding demonstrated that, compared with items presented in the neutral context, items in the positive and negative high-arousing contexts elicited more positive ERPs, which probably reflects an automatic process of attention capturing of high-arousing context as well as a conscious and effortful process of overcoming the interference of high-arousing context. During retrieval, significant FN400 old/new effects occurred in conditions of the negative low-arousing, positive, and neutral contexts but not in the negative high-arousing condition. Significant LPC old/new effects occurred in all conditions of context. However, the LPC old/new effect in the negative high-arousing condition was smaller than that in the positive high-arousing and low-arousing conditions. These results suggest that emotional context might influence both the familiarity and recollection processes. (shrink)

This article assumes that a profession is a number of individuals in the same occupation voluntarily organized to earn a living by openly serving a moral ideal in a morally-permissible way beyond what law, market, morality, and public opinion would otherwise require. Our question is whether the concept of profession may have a far wider range than the term, so that, for example, pointing out that a certain language lacks a word for “profession” in our sense, is not enough to (...) show that those who speak the language also lack the concept. We believe the survey of 71 Chinese reported here begins to answer that question. This article has four parts. The first describes who was interviewed, how, when, and so on. The second describes some important features of the survey’s questions, explaining how the questions track the concept of profession. The third part reports and interprets the results relevant to our question. The forth defends a tentative answer to the question with which we began—arguing the survey supports the claim that China has a profession of engineering. This article should serve as a “proof of concept”, that is, a model for similar studies around the world both of engineering and of other occupations thought to be professions. (shrink)

With the development of teachers’ psychological cognition, the moral education curriculum develops as per the changes in times. Currently, a resurgence of interest on studying teachers’ perceptions of the moral education curriculum has observed. This is because moral education curriculum of each country plays a unique role in the overall design of the country’s education curriculum. However, studies on teachers’ perceptions of the moral education curriculum are scarce, and no framework has been developed to guide the teaching and learning of (...) teachers for the moral education curriculum for schools. The moral education curriculum serves as one of the main vehicles for value education, with teachers as direct executors. It can influence the overall development of the school system and long-term development of a country. Thus, in this paper, we reviewed current literature related to teachers’ perceptions of the moral education curriculum and developed future trends considering teachers’ perceptions of the moral education curriculum in improving existing moral education programs in a country. We identified a list of keywords related to moral education curriculum and teacher perceptions and relevant to the scope of this study. These keywords were used to search the articles from the Scopus and WoS studies. Overall, 32 papers meeting the search criteria were retrieved. Further, we conducted thematic studies, and four themes were successfully identified: the model of teacher perceptions of moral and national education, the dimensions of the teacher ethics model, teaching strategies, and the role of teachers. The results of this study suggested a new framework for research trends in teachers’ perception models, particularly toward the moral education curriculum. This study contributed to the knowledge regarding teaching and learning approaches of moral education considering teachers’ perceptions of the moral education curriculum. The findings of study would benefit future studies and would improve the implementation of a country’s moral education program. (shrink)

Modern socialist economic reforms which center on the establishment of a commodity based economic system, demand a reconsideration of human nature. Marxism and human sociobiology give different answers to questions about human nature, but neither is complete in itself. It seems timely, therefore, to suggest that a combination of biological understanding with a Marxist-based social understanding would produce a more adequate notion of human nature, thereby helping us to resolve a number of problems posed by reforms currently taking place in (...) socialist countries. We might also hope to face new challenges posed in the future. (shrink)

This paper evaluates a theoretical model based on hypothesized relationships among four constructs, namely, autobiographical memory, and place attachment as antecedents of revisit intention and recommendation intention in the context of rural tourism in China. The results of 301 Chinese tourists show that the two dimensions of tourists’ autobiographical memory affect the tourists’ intention to revisit and recommend. Place attachment plays an intermediary role among tourists’ autobiographical memory, revisit intention, and recommendation intention. This study is the first to apply the (...) structural dimension of autobiographical memory has been applied to rural tourism in China. Theoretical and managerial implications are discussed based on the study results. (shrink)

The autophagy initiation complex is brought about via a highly ordered and stepwise assembly process. Two crucial signaling molecules, mTORC1 and AMPK, orchestrate this assembly by phosphorylating/dephosphorylating autophagy‐related proteins. Activation of Atg1 followed by recruitment of both Atg9 vesicles and the PI3K complex I to the PAS (phagophore assembly site) are particularly crucial steps in its formation. Ypt1, a small Rab GTPase in yeast cells, also plays an essential role in the formation of the autophagy initiation complex through multiple regulatory (...) pathways. In this review, our primary focus is to discuss how signaling molecules initiate the assembly of the autophagy initiation complex, and highlight the significant roles of Ypt1 in this process. We end by addressing issues that need future clarification. (shrink)

Mystical religious experiences typically purport to engage with the transcendent and often claim to involve encounters with spiritual entities or a detachment from the material world. Daoism diverges from this paradigm. This paper examines Daoist mystical experiences of bodily transformations and explores their epistemological implications. Specifically, we defend the justificatory power of Daoist somatic experiences against the disanalogy objection. The disanalogy objection posits that mystical experiences, in contrast to sense perceptions, are not socially verifiable and thereby lack prima facie epistemic (...) value. We argue that some Daoist mystical bodily states, being essentially spatiotemporal, are exempt from this challenge. This leads to a broader understanding of mysticism and offers a partial resolution to the disanalogy objection. (shrink)

Considering that the development of urbanization cannot be separated from the application of landscape pattern evolution, in order to improve the development level of ecocity, a modeling analysis of ecological urban landscape pattern evolution based on multisource remote sensing data is proposed. Taking ecotype city as the research object, the remote sensing images of ecological urban landscape pattern are screened by using multisource remote sensing data and nonremote sensing data as the basic data. CA-Markov model is constructed and the evolution (...) of ecological urban landscape pattern is analyzed. The experimental results show that, from 2005 to 2020, the development level of urbanization process is higher and higher and the area of building land patches is increasing, which reduces the fragmentation of building land patches. However, the landscape of cultivated land and green space is less and less, and the distribution of the patches also causes uneven phenomenon, which leads to the gradual decline of ecological urban landscape diversity. In the ecological urban landscape pattern, the degree of fragmentation and diversity of urban landscape is reduced due to the high connection and coverage of the construction land. (shrink)

Early and later Confucians, known in Chinese as the “ruists” school of ancient origins, perceived the idea of “harmony” as a fundamental concept that lies at the basis of self-cultivation, society and governance. In modern times this idea still plays in one or another form a dominant note in Chinese politics and social life. The article attempts to search for causes of the significance of “harmony” by focusing on analyzing two pivotal Confucian texts compiled in the Han dynasty, namely, Records (...) of Music [Yue ji 樂記] and Divination of Music [Yue wei 樂緯]. The analysis shows that ruists belonging to Zhou dynasty’s imperial class of music officials, gradually developed the aesthetics of music into a complex idea of "harmony" that contains the highest aesthetical way—“Dao”—which guides both the whole universe as well as the evolution of human society.
