Conducting effective classroom dialog is an important foundation for high-quality classrooms. This study investigates the characteristics of effective classroom dialog from the perspective of Chinese mathematics classrooms. Classroom videotapes from 40 expert and 33 novice teachers were selected from a national project and analyzed through a developed coding framework. Results showed that the dominant types of dialog in expert teachers’ classrooms were related to Basic Knowledge, Construction, Analysis, and Personal Information. Compared to novice teachers, expert teachers’ classrooms have a significantly (...) lower proportion of dialog on Basic Knowledge and significantly higher proportions of dialog on Personal Information and Speculation. Based on expert teachers’ classrooms, the characteristics of effective classroom dialog in the Chinese context were discussed. The analytical framework for classroom dialog developed in this study could be a powerful tool for subsequent research. Suggestions are provided on increasing the effectiveness of classroom dialog.

One fundamental assumption often made in the literature on unawareness is that risk preferences are invariant to changes of awareness. We study how exposure to unawareness affects choices under risk. Participants in our experiment choose repeatedly between varying sure outcomes and a lottery in three phases. All treatments are exactly identical in phase 1 and phase 3, but differ in phase 2. There are five different treatments pertaining to the lottery faced in phase 2: The control treatment, the treatment with (...) awareness of unawareness of lottery outcomes but known number of outcomes, the treatment with awareness of unawareness of outcomes but with unknown number of outcomes, the treatment with unawareness of unawareness of some outcomes, and the treatment with an ambiguous lottery. We study both whether behavior differs in phase 3 across treatments and whether differences of subjects’ behavior between phases 1 and phase 3 differ across treatments. We observe no significant treatment effects. (shrink)

As an unusual event, fasting can induce strong physiological and psychological reactions, but there is still no clear understanding of how previous fasting experiences affect people’s responses to current fasting. This study aimed to investigate the influence of previous fasting experiences on participants’ basic physiological and psychological responses in a fasting experiment conducted under intensive medical monitoring. For a 22-day experiment divided into four phases, a total of 13 persons participated; the participants were divided into a group with prior fasting (...) experience and a group without prior fasting experience. The results indicate no group differences in physiological responses ; however, differences in psychological states were observed, with the Newbie group showing more negative psychological states overall throughout the experiment. Hence, previous fasting experience may be a buffer against negative feelings during current fasting. For this reason, it is important to consider fasting experiences as a vital factor in future research. (shrink)

This article investigates Charles Peirce’s development of logical calculi for classical propositional logic in 1880–1896. Peirce’s 1880 work on the algebra of logic resulted in a successful calculus for Boolean algebra. This calculus, denoted byPC, is here presented as a sequent calculus and not as a natural deduction system. It is shown that Peirce’s aim was to presentPCas a sequent calculus. The law of distributivity, which Peirce states in 1880, is proved using Peirce’s Rule, which is a residuation, inPC. The (...) transitional systems of the algebra of the copula that Peirce develops since 1880 paved the way to the 1896 graphical system of the alpha graphs. It is shown how the rules of the alpha system reinterpret Boolean algebras, answering Peirce’s statement that logical graphs supply a new system of fundamental assumptions to logical algebra. A proof-theoretic analysis is given for the connection betweenPCand the alpha system. (shrink)

Charles Peirce’s alpha system \ is reformulated into a deep inference system where the rules are given in terms of deep graphical structures and each rule has its symmetrical rule in the system. The proof analysis of \ is given in terms of two embedding theorems: the system \ and Brünnler’s deep inference system for classical propositional logic can be embedded into each other; and the system \ and Gentzen sequent calculus \ can be embedded into each other.

Modern technology (Technik, la technique) has constituted the gears on which the wheels of the modern world keep turning. The later Heidegger devotes sustained reflection to this unprecedented phenomenon in human history. It is notable that, compared with other figures from twentieth-century continental philosophy, Heidegger has served as the most frequent reference point in current philosophy of technology (Technikphilosophie). This field of philosophy came into being after the so-called empirical turn of “Science and Technology Studies.” While relevant scholars focus mainly (...) on “Die Frage nach der Technik” of 1953, “Das Ge-stell” of 1949,1 and some other texts written in that period,2 the time span of Heidegger’s ..

In this essay, we present a theory of intercultural philosophical dialogue and comparative philosophy, drawing on both hermeneutics and analytic philosophy. We advocate the approach of “de-essentialization” across the board. It is true that similarities and differences are always to be observed across languages and traditions, but there exist no immutable cores or essences. “De-essentialization” applies to all “levels” of concepts: everyday notions such as green and qing 青, philosophical concepts such as emotion(s) and qing 情, and philosophical categories such (...) as forms of life and dao 道. We argue that interpretation is a holistic multi-directional process constrained by the principle of mutual attunement. It is necessary to assume that “the other” is a human being, who, in most cases, is consistent and stating that which is true or right. This is the condition of possibility for intercultural philosophical dialogue and comparative philosophy. No more necessary conditions are needed. There is no need to presuppose concepts or categories that are universal for all humans and their languages (such as emotion(s) and qing 情). (shrink)

With the continuous development of the era of big data, community management plays an important role in people’s mental health. Improve people’s mental health through the use of big data to improve governance of the community. To solve the problem, sequence segmentation is used in feature extraction, histogram absolute difference calculation and K-means intelligent algorithm, to analyze the existing problems one by one. Research shows that it is possible to systematically govern the community through big data and intelligent computing, so (...) that community residents can live a higher quality of life. In order to get rid of psychological problems, it can be solved by establishing special psychological support institutions in the community and strengthening the role of the government in community management. With the continuous development of big data, the application of big data and intelligence in community governance and mental health community is a trend. With the continuous progress of society, it also brings pressure to people, which leads to the decline of people’s mental health quality. We need to do something to improve community governance and people’s mental health. (shrink)

This study investigates whether job stressors such as role ambiguity, procedural unfairness, and perceived competition may prompt high Machiavellian employees to use amoral manipulation at work. We also examine whether these manipulative behaviors are consequently related to their own task performance and affiliative citizenship behaviors. A weekly diary study was conducted among 111 Dutch employees over five consecutive working weeks, resulting in 446 assessed occasions. Using a multilevel moderated mediation model, we found that the relationship between weekly job stressors and (...) weekly amoral manipulation (AM) was contingent on trait AM, when the job stressor was role ambiguity (but not when the job stressor was either weekly procedural unfairness or weekly perceived competition). Our results also revealed significant indirect effects of weekly role ambiguity on weekly task performance and weekly display of courtesy through state AM, when trait AM was high. Our findings suggest that role ambiguity activates high Machiavellian employees’ manipulative behaviors at work, which in turn leads to impaired task performance and less courtesy toward others during the same working week.

Bankruptcy of listed companies or shareholders delisting usually causes the crisis spreading in stock markets. Based on the systematic analysis of the epidemic diseases and rumors spreading on the complex networks, the SIR model is introduced to research the crisis spreading in shareholding networks of listed companies and their main holders on the basis of the data about ownership structure in Chinese Stock Markets. The characteristics of shareholding networks are studied, and the parameters for the SIR model are obtained by (...) empirical approach. Then, the numerical computation method is successfully used to analyze the crisis spreading in the networks when the networks meet random failures or intentional attacks. We find the networks have good robustness against the random failures. However, the crisis will spread at a high speed and cause catastrophic damage if there are some failures or attacks on hub vertices in the networks. Under this condition, the networks show obvious vulnerability. Last but not least, the controllability of the networks under the condition of intentional attacks and random failures is studied. The results show that if the network is controlled globally, it is more reliable to allow a politically good new or an appropriate exciting economical policy to play the role in orienting markets under the control of public opinions as the crisis occurs. However, under normal circumstances, controlling a small part of driver vertices representing listed companies, applying appropriate control strategies, and using its characteristics of high efficiency of sending information can effectively control the stock market. Our research provides a new reference to further exploration about the transmission mechanism of the crisis based SIR model and further research on the controllability of crisis spreading in financial markets.

From the tape-recording of naturally occurring Chinese psychotherapy sessions, this article explores how repeated occurrences of resistance are managed in the course of interactional sequences and the participants’ actions within these sequences. By employing the methods of conversation analysis, we discuss the main discursive strategies employed by the clients to express their resistance and investigate how the therapist manages this. We find that clients show their resistance to the therapist’s questions in four ways: keeping silence, providing minimal response, making non-answer (...) responses, and being over-talkative. Persistent asking is the main technique we identify in the data for the therapist to manage the resistance; in the meantime, asking questions in a stepwise way, making requests after facing resistance to questions, active retreating and reformulating of the client’s words are employed as subsidiary techniques. The successful management of resistance leads to a smooth sequential development of the psychotherapy, while inappropriate strategies might result in a halt or even breakdown of the therapeutic work. In psychotherapy, resistance is a result of the shared interaction between client and therapist. It is such a complex issue that, in order to understand and manage it, we also take into consideration the broader social and cultural context in which it occurs. (shrink)

Peirce wrote in late 1901 a text on formal logic using a special Dragon-Head and Dragon-Tail notation in order to express the relation of logical consequence and its properties. These texts have not been referred to in the literature before. We provide a complete reconstruction and transcription of these previously unpublished sets of manuscript sheets and analyse their main content. In the reconstructed text, Peirce is seen to outline both a general theory of deduction and a general theory of consequence (...) relation. The two are the cornerstones of modern logic and have played a crucial role in its development. From the wider perspective, Peirce is led to these theories by three important generalizations: propositions to all signs, truth to scriptibility, and derivation to transformability. We provide an exposition of such proposed semiotic foundation for logical constants and point out a couple of further innovations in this rare text, including the sheet of assertion, correction as a dual of deduction and the nature of conditionals as variably strict conditionals.

Background:Stigma is considered a major barrier to accessing healthcare services by female sex workers. Current knowledge of nurses’ attitudes appears to imply a stigma toward female sex workers. But in-depth understanding of their perceptions is scarce. Furthermore, factors that inform a conceptual understanding of how this occurs are lacking.Objectives:The study aimed to explore nurses’ attitudes toward female sex workers and factors affecting caring for female sex workers.Research design:This was a qualitative study. A content analysis approach was adopted in analyzing the (...) data.Participants and research context:Thirty-three practicing nurses participated in seven semi-structured focus group interviews and three key informants participated in three individual interviews in Hong Kong.Ethical considerations:This study was approved by the Ethics Committee of one university in Hong Kong.Findings:The findings revealed three themes: (1) accept, stigmatize, or against sex work; (2) reluctance, hesitation, or willingness to care for female sex workers; and (3) factors affecting the care of female sex workers.Discussion and conclusion:This study found that nurses held different attitudes toward female sex workers, and they experienced feelings of reluctance, hesitation, or willingness to care for female sex workers. Multi-level factors could affect their level of comfort of caring for female sex workers. Intervention should be developed to encourage health professionals to examine their personal views toward female sex workers introspectively, how their attitude may have affected the provision of quality services, and to enhance the provision of sensitive non-discriminative services to female sex workers.

Peirce introduced Existential Graphs in late 1896, and they were systematically investigated in his 1903 Lowell Lectures. Alpha graphs for classical propositional logic constitute the first part of EGs. The second and the third parts are the beta graphs for first-order logic and the gamma graphs for modal and higher-order logics, among others. As a logical syntax, EGs are two-dimensional graphs, or diagrams, in contrast to the linear algebraic notations. Peirce's theory of EGs is not only a theory of logical (...) syntax but also a proof theory for many logics. A set of transformation rules of graphs defines a proof system for a graphical logic.

Because they are key components of aircraft, improving the safety, reliability and economy of engines is crucial. To ensure flight safety and reduce the cost of maintenance during aircraft engine operation, a prognostics and health management system that focuses on fault diagnosis, health assessment, and life prediction is introduced to solve the problems. Predicting the remaining useful life is the most important information for making decisions about aircraft engine operation and maintenance, and it relies largely on the selection of performance (...) degradation features. The choice of such features is highly significant, but there are some weaknesses in the current algorithm for RUL prediction, notably, the inability to obtain tendencies from the data. Especially with aircraft engines, extracting useful degradation features from multisensor data with complex correlations is a key technical problem that has hindered the implementation of degradation assessment. To solve these problems, deep learning has been proposed in recent years to exploit multiple layers of nonlinear information processing for unsupervised self-learning of features. This paper presents a deep learning approach to predict the RUL of an aircraft engine based on a stacked sparse autoencoder and logistic regression. The stacked sparse autoencoder is used to automatically extract performance degradation features from multiple sensors on the aircraft engine and to fuse multiple features through multilayer self-learning. Logistic regression is used to predict the remaining useful life. However, the hyperparameters of the deep learning, which significantly impact the feature extraction and prediction performance, are determined based on expert experience in most cases. The grid search method is introduced in this paper to optimize the hyperparameters of the proposed aircraft engine RUL prediction model. An application of this method of predicting the RUL of an aircraft engine with a benchmark dataset is employed to demonstrate the effectiveness of the proposed approach. (shrink)

This article is devoted to the consideration of a number of stage projects by Chinese directors, in which the work of the writer Anton Pavlovich Chekhov is reinterpreted. Analysis of such productions and projects as the international drama festival "Chekhov Forever" in 2004, a hybrid work based on Chekhov's story "Three Sisters" and Beckett's novel "Waiting for Godot" by Lin Zhaohua in 1998 and 2018, a double performance by Stan Lai based on the works "I take You by the Hand" (...) by Carol Rocamora and "The Seagull" Chekhov 2014, etc. It allows us to trace innovative approaches to reading Chekhov's works in the context of the life of modern Chinese society. These works cause a great resonance not only in the professional environment, but also among the mass audience, who invariably penetrates the depth of Chekhov's images, the subtlest shades of emotional experiences; the Chinese audience finds themselves close to the problems, hopes and aspirations of the heroes, brilliantly transferred to the actual socio-cultural environment of China, always topical and recognizable. The scientific novelty of the article is connected with the fact that the nature of mastering the creativity of the Russian playwright in the theater of the East is a fairly new and at the same time promising topic for research. The conclusions and results of the study can become the basis for further studies of the specifics of the adaptation of foreign dramaturgy in the national theatrical tradition on the example of other countries and regions.

PurposeThe purpose of this paper is to examine how the shifting conceptualization of the democratizing potential of digital technology can be more comprehensively understood by bringing in science and technology studies perspectives to communication scholarship. The synthesis and discussion are aiming at providing an interdisciplinary theoretical framework for comprehensively understand the democratizing potential of digital technology, and urging researchers to be conscious of assumptions underpinning epistemological positions they take when examining the issue of democratizing potential of digital technology.Design/methodology/approachThe paper is (...) a constructive literature review that synthesizes and integrates existed literature from communication and STS on the democratizing potential of digital technology. The author attempts to bridge theoretical perspectives from communication and STS by identifying core arguments and debates around key concepts and discussing potential implications of different epistemological positions.FindingsTracing the evolving analytical perspectives of technological determinism, the social construction of technology and actor-network theory, the author argues that researchers should be aware of their underlying epistemological assumptions embedded in relationships among users, technological systems and social factors. Analyzing the contested notion of power in the democratizing potential of digital technology from two contrasting perspectives, the author argues that researchers should recognize both the front end and the back end of digital technology in their analysis. In addition, new challenges of algorithm opacity and accountability in impacting the democratizing potential of digital technology are further discussed.Originality/valueThis study provides an original interdisciplinary theoretical framework by reviewing and bridging scholarship from communication and STS in examining the democratizing potential of digital technology. Adopting this interdisciplinary theoretical framework helps researchers develop a more nuanced and comprehensive understanding of the democratizing potential of digital technology. (shrink)

Learning in natural environments is often characterized by a degree of inconsistency from an input. These inconsistencies occur, for example, when learning from more than one source, or when the presence of environmental noise distorts incoming information; as a result, the task faced by the learner becomes ambiguous. In this study, we investigate how learners handle such situations. We focus on the setting where a learner receives and processes a sequence of utterances to master associations between objects and their labels, (...) where the source is inconsistent by design: It uses both “correct” and “incorrect” object‐label pairings. We hypothesize that depending on the order of presentation, the result of the learning may be different. To this end, we consider two types of symbolic learning procedures: the Object‐Label (OL) and the Label‐Object (LO) process. In the OL process, the learner is first exposed to the object, and then the label. In the LO process, this order is reversed. We perform experiments with human subjects, and also construct a computational model that is based on a nonlinear stochastic reinforcement learning algorithm. It is observed experimentally that OL learners are generally better at processing inconsistent input compared to LO learners. We show that the patterns observed in the learning experiments can be reproduced in the simulations if the model includes (a) an ability to regularize the input (and also to do the opposite, i.e., undermatch) and (b) an ability to take account of implicit negative evidence (i.e., interactions among different objects/labels). The model suggests that while both types of learners utilize implicit negative evidence in a similar way, there is a difference in regularization patterns: OL learners regularize the input, whereas LO learners undermatch. As a result, OL learners are able to form a more consistent system of image‐utterance associations, despite the ambiguous learning task. (shrink)

Purpose Privacy has been understood as about one’s own information, information that is not one’s own is not typically considered with regards to an individual’s privacy. This paper aims to draw attention to this issue for conceptualizing privacy when one’s privacy is breached by others’ information. Design/methodology/approach To illustrate the issue that others' information can breach one's own privacy, this paper uses real-world applications of forensic genealogy and recommender systems to motivate the discussion. Findings In both forensic genealogy and recommender (...) systems, the individual’s privacy is breached by information that is not one’s own. The information that breached one’s privacy, by its nature, is beyond the scope of an individual, which is a phenomenon that has already been captured by emerging discussions about group privacy. This paper further argues that the underlying issue reflected by the examples of forensic genealogy is an extreme case even under the consideration of group privacy. This is because, unlike recommender systems that rely on large amounts of data to make inferences about an individual, forensic genealogy exposes one’s identity by using only one other individual’s information. This paper echoes existing discussions that this peculiar situation where others’ information breaches one’s own privacy reveals the problematic nature of conceptualizing privacy relying only on individualistic assumptions. Moreover, this paper suggests a relational perspective as an alternative for theorizing privacy. Originality/value This situation that others’ information breached one’s own privacy calls for an updated understanding of not only privacy but also the relationship between the person and their information. Privacy scholars need to renew their ethical language and vocabularies to properly understand the issue, which recent privacy conceptualizations are already doing (e.g. group privacy). (shrink)

This work is developed to improve the current quality of e-commerce logistics services. From the perspective of multiple consumer psychology, based on e-commerce, consumer psychology, and other related theories, vegetable e-commerce B is selected as the research object. The commodity quality, accuracy, and timeliness of commodity distribution and other factors of e-commerce B are discussed through questionnaire survey. Then, according to customers’ opinions about “e-commerce B’s distribution and professional aspects that need to be improved,” the research is conducted. Finally, the (...) direction of follow-up optimization is proposed from four different perspectives of multiple consumption psychology. The research results show that more than 89% of the surveyed customers believe that e-commerce B does a good job in terms of commodity quality, accuracy, and timeliness of commodity distribution, and has a high level of logistics service. However, 26.34% of customers hope that e-commerce B can strengthen the protection of personal privacy, 24.97% hope that the platform can add “delay insurance” for goods, and 39.54% hope that the logistics information of purchased goods can be updated in real time. Therefore, e-commerce B needs to be optimized and improved continuously in the future development. Therefore, research on the optimization of logistics service quality of e-commerce is performed under multiple consumption psychology, which provides certain help for the rapid development of subsequent e-commerce.
