In order to provide a unified framework for studying non-commutative algebraic logic, Rump and Yang used three axioms to define quantum B-algebras, which can be seen as implicational subreducts of quantales. Based on the work of Rump and Yang, in this paper we shall continue to investigate the properties of three axioms in quantum B-algebras. First, using two axioms we introduce the concept of generalized quantum B-algebras and prove that the opposite of the category GqBAlg of generalized quantum B-algebras is (...) equivalent to the category LogPQ of logical pre-quantales, but we can not prove that pre-quantales can be used as the injective objects in GqBAlg. Next, we use one axiom to propose the concept of C-algebras and show that a C-algebra is a group if and only if each of its elements is dualizing. Further, by dualizing elements of a C-algebra X, we can define different binary operations on X such that X is a moniod. Finally, we by the Zig–Zag relation discuss some properties of quantum B-algebras. (shrink)

We study an application of gaggle theory to unary negative modal operators. First we treat negation as impossibility and get a minimal logic system Ki that has a perp semantics. Dunn 's kite of different negations can be dealt with in the extensions of this basic logic Ki. Next we treat negation as “unnecessity” and use a characteristic semantics for different negations in a kite which is dual to Dunn 's original one. Ku is the minimal logic that has a (...) characteristic semantics. We also show that Shramko's falsification logic FL can be incorporated into some extension of this basic logic Ku. Finally, we unite the two basic logics Ki and Ku together to get a negative modal logic K-, which is dual to the positive modal logic K+ in [7]. Shramko has suggested an extension of Dunn 's kite and also a dual version in [12]. He also suggested combining them into a “united” kite. We give a united semantics for this united kite of negations. (shrink)

Drawing on institutional and signaling theories, this study examines how environmental corporate social responsibility affects firm performance in a dysfunctional institutional environment. We extend the ECSR literature by suggesting that ECSR indirectly influences firm performance through the mediating effects of business and political legitimacy. Based on a dataset of 238 firms in China, we find that ECSR affects business and political legitimacy followed by firm performance. Moreover, legal incompleteness weakens and legal inefficiency strengthens the effects of ECSR on business and (...) political legitimacy. (shrink)

Based on the person-organization fit theory, this research aims to investigate how socially responsible HRM positively affects employees’ organizational citizenship behaviors toward the environment by increasing person-organization fit. This study also captures the moderating effect of the perceived role of ethics and social responsibility in influencing the indirect effect of SRHRM on OCBE via person-organization fit. Data were collected from 302 employees in a state-owned chain hotel in Shanghai, China. The results indicated that SRHRM indirectly influenced employee’s engagement in OCBE (...) through person-organization fit. The positive relationship between SRHRM and person-organization fit and the indirect effect of SRHRM on OCBE via person-organization fit were more significant when employees hold high rather than low levels of RESR. Research implications and prospects were also explored in this study. (shrink)

The purpose of this study was to examine how culture shapes creativity by reviewing empirical findings across diverse studies. The impact of culture on creativity is typically manifested in three ways: (a) people from different cultures or settings have distinct implicit and/or explicit conceptions of creativity; (b) individuals from different cultures, particularly those from individualist and collectivist cultures, show differences in preferred creative processes and creative processing modes (e.g., usefulness seems more important than novelty in the East, whereas novelty seems (...) equally important as usefulness, if not more so, in the West) when they are engaged in creative endeavors; (c) creativity may be assessed using different measures based on culture-related contents or materials, and findings are accurate only when culturally appropriate or culturally fair measures are used. Potential implications and future directions are also proposed. (shrink)

The growing uses of algorithm-based decision-making in human resources management have drawn considerable attention from different stakeholders. While prior literature mainly focused on stakeholders directly related to HR decisions (e.g., employees), this paper pertained to a third-party observer perspective and investigated how consumers would respond to companies’ adoption of algorithm-based HR decision-making. Through five experimental studies, we showed that the adoption of algorithm-based (vs. human-based) HR decision-making could induce consumers’ unfavorable ethicality inferences of the company (study 1); because implementing a (...) calculative and data-driven approach (i.e. algorithm-based) to make employee-related decisions violates the deontological principles of respectful employee treatment (study 2). However, this effect was attenuated when consumers had high (vs. low) power distance beliefs (study 3); the algorithm served as assistance (vs. replacement) for human decisions (study 4); or the adoption was framed as employee-oriented (vs. company-oriented) motivated (study 5). Our findings suggested that consumers are aversive to algorithm-based HR decision-making because it is deontologically problematic regardless of its decision quality (i.e. accuracy). This paper contributes to the extant understanding of stakeholders’ responses to algorithm-based HR decision-making and consumers’ attitudes toward algorithm users. (shrink)

Grounded on the social exchange theory (SET), social cognitive theory (SCT), and self-determination theory (SDT), this study aims to explore the mediating role of self-efficacy (SE) and work engagement (WE) on the effect of social support (SS) on job satisfaction (JS) among Chinese ethnic minority kindergarten teachers (KTs). The results show that: (1) SS has a directly significant effect on JS; (2) WE mediates the relationship between SS and JS; and (3) SE mediates the relationship between SS and WE. Although (...) the mediation of SE on the relationship between SS and JS is not found, the posited multiple mediations of SE and WE on the relationship between SS and JS are totally accepted. The results reveal that SS mainland Chinese ethnic minority KTs received can not only have a direct effect on JS but also have an indirect impact through the one-path mediating role of WE and the chain mediating role of SE and WE. The results suggest that governments, supervisors, and sponsors should work together to provide ethnic minority KTs with more prioritized SS from both cultural psychology and financial material and opportunities for facilitating professional knowledge and skills in order to enhance their SE, inspire their WE, and eventually accumulate their JS.

Three hundred and seventy-six middle school students in Wenchuan County were assessed three and one-half years after the Wenchuan earthquake to examine the effects of rumination on posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). The results revealed that recent intrusive ruminations partly mediated the relationship between intrusive rumination soon after the earthquake with PTSD but not with PTG. Recent deliberate rumination partly mediated the relationship between intrusive rumination soon after the earthquake and PTG but not PTSD. Moreover, recent deliberate (...) rumination also partly mediated the relationship between recent intrusive rumination with PTG but not with PTSD. Overall, intrusive rumination soon after the earthquake had an effect on PTSD but not on PTG through recent intrusive rumination and affected PTG but not PTSD through deliberate recent rumination. Furthermore, intrusive rumination soon after the earthquake affected PTG but not PTSD by recent deliberate rumination following recent intrusive rumination. More importantly, the present study also found that PTSD exhibited no relation to PTG. These results suggest that PTSD and PTG are influenced by different mechanisms, which further indicates that PTSD and PTG represent two separate dimensions of experience after adversity. (shrink)

In previous experiments on unconscious thought, information was presented to participants in one continuous session; however, in daily life, information is delivered in a temporally partitioned way. We examined whether unconscious thought could equally integrate temporally scattered information when making overall evaluations. When presenting participants with information in two temporally partitioned sessions, participants’ overall evaluation was based on neither the information in the first session nor that in the second session ; instead, information in both sessions were equally integrated to (...) reach a final judgment. Conscious thought, however, overemphasized information in the second session. Experiments 3 and 4 further ruled out possible influencing factors including differences in the distributions of positive/negative attributes in the first and second sessions and on-line judgment. These findings suggested that unconscious thought can integrate information from a wider range of periods during an evaluation, while conscious thought cannot. (shrink)

RNA localization is a powerful strategy used by cells to localize proteins to subcellular domains and to control protein synthesis regionally. In germ cells, RNA targeting has profound implications for development, setting up polarities in genetic information that drive cell fate during embryogenesis. The frog oocyte offers a useful system for studying the mechanism of RNA localization. Here, we discuss critically the process of RNA localization during frog oogenesis. Three major pathways have been identified that are temporally and spatially separated (...) in oogenesis. Each pathway uses a different mechanism to effect RNA localization. In some cases, localization elements within the 3' untranslated region have been identified and have provided unique insights into the localization process. This important field is still in its infancy, however, and much remains to be learned. BioEssays 21:546–557, 1999. © 1999 John Wiley & Sons, Inc. (shrink)

There is a growing consensus that the mental lexicon contains both abstract and word-specific acoustic information. To investigate their relative importance for word recognition, we tested to what extent perceptual learning is word specific or generalizable to other words. In an exposure phase, participants were divided into two groups; each group was semantically biased to interpret an ambiguous Mandarin tone contour as either tone1 or tone2. In a subsequent test phase, the perception of ambiguous contours was dependent on the exposure (...) phase: Participants who heard ambiguous contours as tone1 during exposure were more likely to perceive ambiguous contours as tone1 than participants who heard ambiguous contours as tone2 during exposure. This learning effect was only slightly larger for previously encountered than for not previously encountered words. The results speak for an architecture with prelexical analysis of phonological categories to achieve both lexical access and episodic storage of exemplars. (shrink)

Pneumatic muscle actuators own excellent compliance and a high power-to-weight ratio and have been widely used in bionic robots and rehabilitated robots. However, the high nonlinear characteristics of PMAs due to inherent construction and pneumatic driving principle bring great challenges in applications acquired accurately modeling and controlling. To tackle the tricky problem, a single PMA mass setup is constructed, and a back propagation neural network is employed to identify the dynamics of the setup. An offline model is built up using (...) sampled data, and online modifications are performed to further improve the quality of the model. An adaptive controller based on BPNN is designed using gradient descent information of the built-up model. Experiments of identifying the PMA setup using BPNN and position tracking by adaptive BPNN controller are performed, and results demonstrate the good capacity in accurate controlling of the PMA setup.

A case study of Chinese grandparents’ transnational caregiving experiences in Canada highlights two issues that have received limited attention in the broader feminist care literature: (1) elderly persons are usually positioned as receivers rather than providers of care; and (2) transnational care studies focus on women migrating as part of “global care chains,” rather than on elderly family members migrating to meet the caring needs of adult kin who work in market economies that do not recognize caring responsibilities. The paper (...) concludes by arguing that the distribution of care responsibilities needs to be one of the pillars in the pursuit of transnational social justice. (shrink)

ObjectiveTwo subregions of the dorsolateral prefrontal cortex have been identified as effective repetitive transcranial magnetic stimulation targets for the “anxiosomatic” and “dysphoric” symptoms, respectively. We aimed to develop a convenient approach to locate these targets on the scalp.Materials and methodsIn a discovery experiment, the two personalized targets were precisely identified on 24 subjects using a neuronavigation system. Then, a localized approach was developed based on individual scalp landmarks. This “landmark-based approach” was replicated and validated in an independent cohort. Reliability of (...) the approach was tested by calculating the correlation of both the inter-rater and intra-rater results. Validity was tested by comparing the mean distance between the personalized and landmark-based targets to the TMS spatial resolution. We further conducted a total of 24 sham rTMS sessions to estimate the misplacement between the coil center and target during a 10-min stimulation without neuronavigation.ResultsThe parameters of the “landmark-based approach” in the discovery experiment were replicated well in an independent cohort. Using discovery parameters, we successfully identified the symptom-specific targets in the independent cohort. Specifically, the mean distance between the personalized and landmark-based targets on the cortex was not significantly larger than 5 mm. However, the personalized and landmark-based targets distance exceeded 5 mm in more than 50% of subjects. During the 10-min sham rTMS session, the average coil misplacement was significantly larger than 5 mm.ConclusionThe “landmark-based approach” can conveniently and reliably locate the two symptom-specific targets at group level. However, the accuracy was highly varied at individual level and further improvement is needed. (shrink)

This research aims to analyze the influencing factors of migrant children’s education integration based on the convolutional neural network algorithm. The attention mechanism, LSTM, and GRU are introduced based on the CNN algorithm, to establish an ALGCNN model for text classification. Film and television review data set, Stanford sentiment data set, and news opinion data set are used to analyze the classification accuracy, loss value, Hamming loss, precision, recall, and micro-F1 of the ALGCNN model. Then, on the big data platform, (...) data in the Comprehensive Management System of Floating Population and Rental Housing, Student Status Information Management System, and Student Information Management System of Beijing city are taken as samples. The ALGCNN model is used to classify and compare related data. It is found that in the MR, STT, and MPQA data sets, the classification accuracy and loss value of the ALGCNN model are better than other algorithms. HL is the lowest, the Pre is second only to the BERT algorithm, and the Re and F1 are both higher than other algorithms. From 2015 to 2019, the number of migrant children in different grades of elementary school shows a gradual increase. Among migrant children, the number of migrant children from other counties in this province is evidently higher than the number of migrant children from other provinces. Among children of migrant workers, the number of immigrants from other counties in this province is also notably higher than the number of immigrants from other provinces. With the gradual increase in the years, the proportion of township-level expenses shows a gradual decrease, whereas the proportion of district and county-level expenses shows a gradual increase. Moreover, the accuracy of the ALGCNN model in migrant children and local children data classification is 98.6 and 98.9%, respectively. The proportion of migrant children in the first and second grades of a primary school in Beijing city is obviously higher than that of local children. The average final score of local children was greatly higher than that of migrant children, whereas the scores of migrant children’s listening methods, learning skills, and learning environment adaptability are lower, which shows that an effective text classification model is established based on the CNN algorithm. In short, the children’s education costs, listening methods, learning skills, and learning environment adaptability are the main factors affecting migrant children’s educational integration, and this work provides a reference for the analysis of migrant children’s educational integration.

Resumo: Um parque cultural urbano é um símbolo da cultura urbana regional, além de refletir o acúmulo da cultura humana. Ele pode se tornar uma forma importante de herdar o patrimônio cultural e histórico regional e de promover o excelente espírito cultural tradicional chinês. Entretanto, o papel cultural desempenhado pelos parques culturais é bastante insatisfatório e ainda necessita de melhorias. É extremamente importante resolver esses problemas e promover o design dos parques culturais urbanos, a fim de mostrar melhor suas ideias (...) culturais e suprir as necessidades de disseminação e desenvolvimento culturais. Por isso, este artigo introduziu elementos de montanhas e analisou a simbólica importância deles no design de parques culturais urbanos. Esta investigação tentou interpretar as ideias contidas nos parques culturais urbanos modernos, a partir das perspectivas de parques culturais urbanos e elementos de montanhas, e elaborou estratégias de design, métodos de expressão, técnicas de expressão e troca de ideias sobre parques culturais urbanos. As pesquisas mostraram que introduzir elementos de montanhas no design de parques culturais pode torná-los mais agradáveis esteticamente, com formatos mais complexos, de modo a destacar melhor as ideias de temas para interpretações e expressões culturais regionais. Esta pesquisa oferece mais projetos de design e elementos para o design de parques culturais urbanos, estudando os elementos de montanhas, enriquecendo a expressão e o significado ideológicos de parques culturais urbanos, ajudando a promover o patrimônio e o desenvolvimento da cultura e fornecendo mais base teórica para o design de paisagens.

Reproductive diseases are a long‐standing problem and have become more common in the world. Currently, 15% of the world's population suffers from infertility, and half of them are women. Maturation of oocytes, successful fertilization, and high‐quality embryos are prerequisites for pregnancy. With the development of assisted reproductive technology and advanced genetic assays, we have found that infertility in many young female patients is caused by mutations in various developmental regulators. These pathogenic factors may result in impediment of oocyte maturation, failure (...) of fertilization or early embryonic development arrest. In this review, we categorize these clinically‐identified, mutated genetic factors by their molecular characteristics: nuclear factors (PALT2, TRIP13, WEE2, TBPL2, REC114, MEI1 and CDC20), cytoplasmic factors (TLE6, PADI6, NLRP2/5, FBXO43, MOS and BTG4), a factor unique to primates (TUBB8), cell membrane factor (PANX1), and zona pellucida factors (ZP1‐3). We compared discrepancies observed in phenotypes between human and mouse models to provide clues for clinical diagnosis and treatment of related reproductive diseases. (shrink)

Partitioner algebras are defined by Baumgartner and Weese 619) as a natural tool for studying the properties of maximal almost disjoint families of subsets of ω.

It has limitations to understand “fidelity” of the Analects of Confucius in the thinking pattern of subject-object. The interpretation patterns of self-other and private-public ethics can’t also completely explain the philosophical meaning of “fidelity” in the Analects of Confucius. “Fidelity”, in Confucian theory and practice, has important place, therefore, the paper will try to explore the philosophical meaning of “fidelity” of Confucius from the following suppositions in order to find a new way of philosophical explanation. The suppositions are as the (...) following: First of all, “fidelity” can’t be understood, in Chinese, as a verb which means “faithful to sb”. It is a noun or a gerund. Basing on the distinction of “material world” and “meaning world”, the paper holds that the connotation of “fidelity” has its inner regulation and its meaning is, first of all, regulated not by the material world but by the other contextual logic categories, in this way, it has the characteristic of independence and transcendence. The core meaning of “fidelity” is “center”, the paper calls it as “the centric wisdom” from the epistemological perspective. Wesuppose that Confucius has presupposed that every life has enough wisdom to know what the affirmative value is. For Confucius, his philosophical thinking on “fidelity” has both traditional heritage and personal innovation. We should pay attention to the latter. Basing on the understanding that takes “fidelity ”as “the centric wisdom”, the paper holds that one of the meanings of “fidelity”, as an ethical concept, in the Analects of Confucius, is personal ethics which includes thereorganization of individual values. One part of the individual value is to recognize and practice the value which is independent of social value. Another part of the value is to practice and exhibit the wisdom of “fidelity” in personal speech and behavior including the spiritual activities. The “fidelity” of the Analects of Confucius, as an ethical concept, has another meaning, i.e. the inter-personal relationship which shows the affirmative value under the guidance of wisdom. The inter-personal relationship under the guidance of wisdom can exhibit the affirmative value and can be called as the “ethical” relation. The main requirements are as the following: we have to bring the reflective factor of “wisdom” into inter-personal relation and, under the guidance of wisdom, try to take our social responsibilities required by the social role, or to abide by the public or the professional ethics. We have to maintain positive value direction in the verticalinter-personal relation which means supervision so as to realize the political affirmation. In the horizontal interpersonal relationship, basing on the individual wisdom, we have to keep the keen feeling of morality so as to realize our affirmative values. The understanding of these meanings concerning the word of “fidelity” is naturally resulted from our concern for the inner logic relation in the Analects of Confucius and for the form of idea-expressing of Confucius.

The purpose of this study is to investigate the characteristics, relationships and mechanisms underlying the psychological capital, career commitment, gratitude and career well-being of teachers in ethnic areas. In total, 573 primary school and secondary school teachers in Sichuan Province were investigated. Following questionnaires were used to investigate these questions: “Psychological Capital Questionnaire for Primary and Secondary School Teachers,” “Gratitude Questionnaire,” “Teacher Career Well-being Questionnaire” and “Career Commitment Questionnaire for Primary and Secondary School Teachers.” The results show that the psychological (...) capital of teachers in ethnic areas is higher than that of teachers in non-ethnic areas. Teachers in ethnic areas have lower levels of career well-being and lower levels of gratitude than teachers in non-ethnic areas. There was no significant difference in career commitment between teachers in ethnic areas and teachers in non-ethnic areas. There were significant positive correlations among psychological capital, gratitude, career well-being and career commitment. Psychological capital can predict career commitment significantly and positively. The mediating effect of career well-being between teachers’ psychological capital and career commitment was significant in both ethnic areas and non-ethnic areas. The chain of mediating effects between gratitude and career well-being was significant in non-ethnic areas. In conclusion, psychological capital can predict teacher career commitment effectively, and the prediction mechanism in ethnic areas is different from that in non-ethnic areas. (shrink)

Ecopsychology holds that a full-fledged self should be in harmony with nature, but when the human’s social self, consumptive false self, and paranoid cultural narcissism prevail, the ecological self goes from dominant existence to recessive existence. Because of this predicament with regard to the ecological self, one should make full use of wildness spirit to reshape the ecological self. Due to the abstract nature of the wilderness spirit and in an attempt to present the wilderness spirit in a more concrete (...) and vivid way, the wilderness spirit needs to be set apart from wilderness literature so as to analyze the role that the wilderness spirit plays in rebuilding the ecological self.

Axons are the longest cellular structure reaching over a meter in the case of human motor axons. They have a relatively small diameter and contain several cytoskeletal elements that mediate both material and information exchange within neurons. Recently, a novel type of axonal plasticity, termed axonal radial contractility, has been unveiled. It is represented by dynamic and transient diameter changes of the axon shaft to accommodate the passages of large organelles. Mechanisms underpinning this plasticity are not fully understood. Here, we (...) first summarised recent evidence of the functional relevance for axon radial contractility, then discussed the underlying structural basis, reviewing nanoscopic evidence of the subtle changes. Two models are proposed to explain how actomyosin rings are organised. Possible roles of non‐muscle myosin II (NM‐II) in axon degeneration are discussed. Finally, we discuss the concept of periodic functional nanodomains, which could sense extracellular cues and coordinate the axonal responses.

This research aims to study art and religious philosophy by analyzing the significance of Aboriginal dot painting, Sichuan opera makeup, Chinese traditional sculpture and Shu embroidery. A particular emphasis is placed upon their crucial importance for understanding the essence of various societies as well as their main spiritual and cultural tenets. The data for this study was gathered using a qualitative approach, targeted toward online museums and cultural websites, focusing on images of artworks to determine the parameters of symbolic elements (...) in terms of culture and religion. Purposeful sampling was used to identify pieces of art that not only have meaningful religious symbolisms but also different cultural backgrounds. Such sampling assures that the study embodies a wide representation of religious semiotics and a better understanding of the interaction between art and spirituality. This study shows that irrespective of culture, one can identify an analogy of how signs and icons work with the message from the divine, which is further preserved from the sacred. These art symbols embody theological metaphors on ethical, aesthetic, and cultural dimensions and express semantic meanings across cultures. Since the data for the study was limited to only online sources and predefined cultural artefacts, it may lack the field intensity of first-hand observation across cultures. Future research should identify multiple data sources and conduct additional cross-cultural comparisons of more cultures and other forms of art. (shrink)

Specific to the NCSs where sensor signals can be processed centrally, a collaborative design scheme of dynamic game scheduling and advanced control theory was proposed in the present study. Firstly, by using the Jordan standard state space equation of the research object, the three elements of state noncooperative game were built, and the existence and uniqueness of Nash equilibrium solution were verified. In addition, the iterative equation of the scheduling matrix was derived by complying with the designed utility function. Secondly, (...) refer to the number of restricted states the order of sliding mode was determined. And based on it, the corresponding sliding surface was designed. Subsequently, the quadratic optimization theory was adopted to regulate the control value following the implementation of the scheduling strategy to ensure that the control quality was further enhanced in the limited network service. Lastly, a TrueTime simulation example is established to verify the effectiveness of the proposed scheme. (shrink)

Recently, creative deviance has been lauded to be an innovation-enhancing approach with applications in many new and high-tech domains. Previous study on antecedents to creative deviance remains scattered and vague. Our research conceptualizes creative deviance from the perspective of independent innovation and explores its antecedents, mechanisms, as well as conditions. Team authoritarian leadership is conceptualized as a contradictory unity as it mixes advantages and disadvantages. However, it is surprising to find that there are very few researches that have examined its (...) relevant influence mechanisms and boundary conditions for authoritarian leadership. Contributing to an advanced understanding of authoritarian leadership in research and development teams, we investigated whether team authoritarian leadership is positively or negatively related to creative deviance. Drawing on social information processing theory and regulatory focus theory, we supposed that team authoritarian leadership facilitates creative deviance when the degree is low and inhibits it when the degree is high; dual occupational stress and prevention regulatory focus play mediation roles between team authoritarian leadership and creative deviance respectively, both variables play a chain mediation role in that relationship; and the mindfulness characteristic of an individual moderates the inverted-U team authoritarian leadership-creative deviance association, such that this association is weaker with low individual mindfulness. With two-phase questionnaire data collected from 433 members in 82 R&D teams of high-tech enterprises in electronic information technology, new material technology, new medical technology, resource and environment technology and advanced manufacturing technology randomly selected from five provinces in eastern China, these hypotheses are supported empirically. Overall, we find that, our study broadens antecedents and the relevant occurrence mechanisms of creative deviance when studied through a leadership management lens. Moreover, our research enriches the cognate studies on authoritarian leadership by empirically demonstrating that team authoritarian leadership may function as an double-edged sword of creative deviance in the R&D workplace. These above findings offer insightful thoughts to scholars in the field of authoritarian leadership and bring practical suggestions for team superiors who seek to implement best innovation practice.

Maintaining accurate and precise temporal perception under conditions of stress is important. Studies in animal models and clinic patients have suggested that time perception can change under chronic stress. Little is known, however, about the relationship between chronic stress and time perception in healthy individuals. Here, a sample of 62 healthy young men completed Cohen’s Perceived Stress Scale (PSS) as a measure of chronic stress levels, while time perception was measured using a temporal bisection task. This task used short (400 (...) ms) and long (1600 ms) visual signals as anchor durations. Participants were presented with a range of intermediate probe durations and were required to judge whether the durations were more similar to the short or the long anchor. Results showed that chronic stress was negatively related to temporal sensitivity indexed by the Weber ratio. However, there was no significant correlation between chronic stress and subjective duration indexed by the bisection point. These results demonstrate that higher chronic stress is associated with lower temporal sensitivity and thus provide evidence for a link between chronic stress and time perception in healthy adults.

Mining time series data is of great significance in various areas. To efficiently find representative patterns in these data, this article focuses on the definition of a valid dissimilarity measure and the acceleration of partitioning clustering, a common group of techniques used to discover typical shapes of time series. Dissimilarity measure is a crucial component in clustering. It is required, by some particular applications, to be invariant to specific transformations. The rationale for using the angle between two time series to (...) define a dissimilarity is analyzed. Moreover, our proposed measure satisfies the triangle inequality with specific restrictions. This property can be employed to accelerate clustering. An integrated algorithm is proposed. The experiments show that angle-based dissimilarity captures the essence of time series patterns that are invariant to amplitude scaling. In addition, the accelerated algorithm outperforms the standard one as redundancies are pruned. Our approach has been applied to discover typical patterns of information diffusion in an online social network. Analyses revealed the formation mechanisms of different patterns. (shrink)

Bosbach and Riečan states on residuated lattices both are generalizations of probability measures on Boolean algebras. Just from the observation that both of them can be defined by using the canonical structure of the standard MV-algebra on the unit interval [0, 1], generalized Riečan states and two types of generalized Bosbach states on residuated lattices were recently introduced by Georgescu and Mureşan through replacing the standard MV-algebra with arbitrary residuated lattices as codomains. In the present paper, the Glivenko theorem is (...) first extended to residuated lattices with a nucleus, which gives several necessary and sufficient conditions for the underlying nucleus to be a residuated lattice homomorphism. Then it is proved that every generalized Bosbach state (of type I, or of type II) compatible with the nucleus on a nucleus-based-Glivenko residuated lattice is uniquely determined by its restriction on the nucleus image of the underlying residuated lattice, and every relatively generalized Riečan state compatible with the double relative negation on an arbitrary residuated lattice is uniquely determined by its restriction on the double relative negation image of the residuated lattice. Our results indicate that many-valued probability theory compatible with nuclei on residuated lattices reduces in essence to probability theory on algebras of fixpoints of the underlying nuclei.
