Music rhythm detection and tracking is an important part of the music comprehension system and visualization system. The music signal is subjected to a short-time Fourier transform to obtain the frequency spectrum. According to the perception characteristics of the human auditory system, the spectrum amplitude is logarithmically processed, and the endpoint intensity curve and the phase information of the peak value are output through half-wave rectification. The Pulse Code Modulation characteristic value is extracted according to the autocorrelation characteristic of the (...) endpoint intensity curve. This article proposes a rhythm detection algorithm based on multipath search and cluster analysis; that is, based on the clustering algorithm, it absorbs the idea of multipath tracking and proposes its own detection and tracking algorithm. It overcomes the weakness of the clustering algorithm that needs to use Musical Instrument Digital Interface auxiliary input to achieve the desired effect. This algorithm completely uses the PCM signal as the input, which is more robust than the clustering algorithm. The whole process is carried out in the time domain, and the amount of calculation is much smaller than the frequency domain calculation of multipath tracking, and the linear relationship with the rhythm of the music is much better than the filter bank algorithm. This algorithm can successfully detect the rhythm of the music with a strong sense of rhythm and can track the specific position of the rhythm point. (shrink)

The minimal weakening \ of Belnap-Dunn logic under the polarity semantics for negation as a modal operator is formulated as a sequent system which is characterized by the class of all birelational frames. Some extensions of \ with additional sequents as axioms are introduced. In particular, all three modal negation logics characterized by a frame with a single state are formalized as extensions of \. These logics have the finite model property and they are decidable.

How did human vocalizations come to acquire meaning in the evolution of our species? Charles Darwin proposed that language and music originated from a common emotional signal system based on the imitation and modification of sounds in nature. This protolanguage is thought to have diverged into two separate systems, with speech prioritizing referential functionality and music prioritizing emotional functionality. However, there has never been an attempt to empirically evaluate the hypothesis that a single communication system can split into two functionally (...) distinct systems that are characterized by music- and languagelike properties. Here, we demonstrate that when referential and emotional functions are introduced into an artificial communication system, that system will diverge into vocalization forms with speech- and music-like properties, respectively. Participants heard novel vocalizations as part of a learning task. Half referred to physical entities and half functioned to communicate emotional states. Participants then reproduced each sound with the defined communicative intention in mind. Each recorded vocalization was used as the input for another participant in a serial reproduction paradigm, and this procedure was iterated to create 15 chains of five participants each. Referential vocalizations were rated as more speech-like, whereas emotional vocalizations were rated as more music-like, and this association was observed cross-culturally. In addition, a stable separation of the acoustic profiles of referential and emotional vocalizations emerged, with some attributes diverging immediately and others diverging gradually across iterations. The findings align with Darwin’s hypothesis and provide insight into the roles of biological and cultural evolution in the divergence of language and music. (shrink)

Why should interpretation of conceptual schemes and practices across traditions work at all? In this paper we present the following necessary conditions of possibility for interpretation in comparative and Chinese philosophy: the interpreter must presuppose that there are mutually recognizable human practices; the interpreter must presuppose that “the other” is, on the whole, sincere, consistent, and right; the interpreter must be committed to certain epistemic virtues. Some of these necessary conditions are consistent with the fact that interpretation is not thwarted (...) by the “danger” of relativism or of incommensurability. Some other conditions are suggestive of reorientations of methodologies of comparative and Chinese philosophy. (shrink)

The language of Belnap–Dunn modal logic \ expands the language of Belnap–Dunn four-valued logic with the modal operator \. We introduce the polarity semantics for \ and its two expansions \ and \ with value operators. The local finitary consequence relation \ in the language \ with respect to the class of all frames is axiomatized by a sequent system \ where \. We prove by using translations between sequents and formulas that these languages under the polarity semantics have the (...) same expressive power on the level of frames with the language \ under the relational semantics for classical modal logic.

The innovation activities of new generation of employees have the characteristics of double network embeddedness, and the degree of psychological contract fulfilment is an important factor that affects their innovation performance. Based on the attributes of internal network embeddedness and external network embeddedness, this paper builds a hypothesis model of the relationship between network embeddedness, psychological contract and innovation performance. It explores the impact and mechanism of network embeddedness on the innovation performance of new generation of employees and the mediating (...) role of the psychological contract. Empirical research shows that network embeddedness has a positive effect on the innovation performance of new generation of employees. The psychological contract has a mediating role in network embeddedness on innovation performance of new generation of employees. These conclusions continue and deepen the research on network embeddedness and innovation performance and further enrich and expand the application of social networks in the research of individual innovation performance of new generation of employees.

Although the proliferation of empirical research has documented the association between parental control and school adjustment, findings of this linkage are still inconclusive. Moreover, fewer efforts have been made to address this association in middle school students. Guided by an ecological framework, the current study aimed to integrate the conflicting findings into a coherent body of knowledge, paying particular attention to two research purposes: (a) to examine the association between parental control and three objective indicators of school adjustment (social competence, (...) academic grades, and peer acceptance), and (b) to explore whether this association was moderated by individual characteristics of social identity and grit. A total of 120 Chinese middle school students (42.5% females) aged between 13 and 15 years old were recruited for this study, and research data was gathered from multiple sources. To be specific, students were asked to complete a set of self-report questionnaires concerning parental control, social identity, and grit. Meanwhile, school-related social competence was rated by head teachers; academic grades were obtained from school records; peer acceptance was assessed by sociometric nominations. The results from hierarchical regression analyses showed that parental control was negatively associated with academic grades. Moreover, when reporting higher levels of social identity, parental control was negatively related to social competence and peer acceptance for those students with lower levels of grit. Our findings suggest that parental control can dampen middle school students’ academic performance, and low levels of grit can magnify the detrimental effect of parental control on social competence and peer acceptance in middle school students who regard themselves as closely connected to social groups.

This paper presents a bioinspired lower extremity exoskeleton robot. The proposed exoskeleton robot can be adjusted in structure to meet the wearer’s height of 150–185 cm and has a good gait stability. In the gait control part, a method of identifying different locomotion modes is proposed; five common locomotion modes are considered in this paper, including sitting down, standing up, level-ground walking, ascending stairs, and descending stairs. The identification is depended on angle information of the hip, knee, and ankle joints. (...) A deep locomotion mode identification model based on long-short term memory architecture is proposed in this paper for exploiting the angle data. We conducted two experiments to verify the effectiveness of the proposed method. Experimental results show that the DLMIM is capable of learning inherent characteristics of joint angles and achieves more accurate identification than the other models. The last experiment demonstrates that the DLMIM can recognize transitions between different locomotion modes in time and the real-time performance varies with each individual. (shrink)

ABSTRACT This corpus-assisted critical discourse study examines news reports published by China’s official English-language media from 2000 to 2018, with the goal of understanding how they represent LGBTQ+ issues within the China’s socio-political context. Analysis reveals that the discussion of LGBTQ+-related topics has been consistently discouraged in China’s official English-language media, and the few news reports which have appeared in these media sources have focused on preventing the spread of HIV/aids through homosexual behaviors, on promoting LGBTQ+ rights, and on advocating (...) for the liberalization of sex education in China. The range of these focuses indicates that, despite widely-held negative stereotypes regarding homosexual behaviors and their relation to the spread of HIV/aids, the official English-language media of China have endeavored to project a positive image of the Chinese central government’s efforts to construct a society that is open, inclusive, and tolerant of LGBTQ+ individuals. This study also discusses positive changes in the social well-being of LGBTQ+ persons in China as evidenced first by the more liberal attitudes that gradually have resulted from the efforts of Chinese netizens to influence LGBTQ+-related governmental policies and second, by the more positive representations of LGBTQ+ issues being communicated to global audiences through the China’s official English-language media.

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)

The main aim of this essay is to show that, for Stevens, the concept of reality is very fluctuating. The essay begins with addressing the relationship between poetry and philosophy. I argue, contra Critchley, that Stevens’ poetic work can elucidate, or at least help us to understand better, the ideas of philosophers that are usually considered obscure. The main “obscure” philosophical work introduced in and discussed throughout the essay is Schelling’s System of Transcendental Idealism. Both a (shellingian) philosopher and a (...) (stevensian) poet search for reality. In order to understand Stevens’ poetry better, I distingush several concepts of reality: initial reality (the external world of the common sense), imagined reality (a fiction, a product of one’s mind), final reality (the object of a philosopher’s and a poet’s search) and total reality (the sum of all realities, Being). These determinations are fixed by reason (in the present essay), whereas in Stevens’ poetic works, they are made fluid by the imagination. This fluidity leads the concept of reality from its initial stage through the imagined stage to its final stage. Throughout this process, imagined reality must be distinguished from both a mere fancy and its products. Final reality is, however, nothing transcendent. It is rather a general transpersonal order of reality created by poetry/the imagination. The main peculiarity of final reality is that it is a dynamic order. It is provisional at each moment. Stevens (and Schelling too) characterizes this order as that of a work of art which is a finite object, but has an infinite meaning. Stevens calls this order “the central poem” or the “endlessly elaborating poem”. If ultimate reality is a poem created by the imagination, one may ask who is the imagining subject. I argue that this agent is best to be thought as total reality, that is, as Being. Stevens, however, maintains that if there were such an agency, it would be an inhuman agency, “an inhuman meditation”. The essay concludes, in a Derridian manner, with the claim that this agency cannot have any name; it is the “unnamed creator of an unknown sphere, / Unknown as yet, unknowable, / Uncertain certainty” (OP: 127). It is best thought as an X, as an unknown variable. Being has no name. (shrink)

Két, közelmúltban megrendezett filozófiai konferencia előadásaiból válogat a tanulmánykötet. A 2015-ben a kaposvári egyetemen és 2016-ban a Filozófiai Intézetben megtartott tanácskozások témája az érzelmek és a jelentés volt. Az érzelmek mibenléte, az ésszel és értelemmel való kapcsolata már a kezdetek óta foglalkoztatta a filozófusokat, érthető hát, hogy a kötet élén két filozófiatörténeti esettanulmány áll, az első az ókori sztoikusoknál vizsgálja az érzelmek és a cselekvés viszonyát, a másik a bűnös érzelmek problémáját mutatja be a skolasztika korában. A folytatásban már a (...) kortárs filozófiai viták egy-egy témája kerül elő: az éntapasztalat fenomenológiai leírása és az érzelmek lehetséges szerepe a racionális vitákban. Az érzelmekről szóló blokkot záró két kognitív pszichológiai tanulmány az empirikus tudományok felől közelíti meg a problémakört. A kiadvány második felében található négy tanulmányt a huszadik századi filozófia egyik kulcsfogalma, a jelentés köti össze, amelynek kapcsán nyelv- és elmefilozófiai problémák kerülnek tárgyalásra: intencionalitás és fenomenalitás viszonya, a szemantikai szkepticizmus, a vélekedések filozófiai leírása. A kortárs filozófiai diskurzusokba betekintést nyújtó, a szerkesztők rövid előszavával bevezetett kiadvány a szakkönyvtárak anyaga. "www.kello.hu © minden jog fenntartva". (shrink)

This collection of short essays on texts in the history of democracy shows the diversity of ideas that contributed to the making of our present democratic moment. The selection of texts goes beyond the standard, Western-centric canonical history of democracy, with its beginnings in Ancient Athens and its climax in the French and American revolutions, recovering some of the significant body of democratic and anti-democratic thought in Latin America, Asia, and elsewhere. It includes discussions of well-known philosophers like Plato and (...) Aristotle, but also of a variety of thinkers much less well known in English as writers on democracy: Al Farabi, Bolívar, Gandhi, Radishchev, Lenin, Sun Yat-sen, and many others. The essays thus de-center our understanding of the moments where the idea of democracy was articulated, rejected, and appropriated. Spanning antiquity to the present and global in scope, with contributions by key scholars of democracy from around the world, Democratic Moments is the ideal text for all students wishing to expand their understanding of the ways in which this contested concept has been understood.
