Research about improvisation often focuses on one musical tradition. The current study investigated descriptions of thinking behind improvisation in different cultural traditions through interviews with advanced improvisers residing in a metropolitan area in the United States. The participants were rigorously trained in their tradition and have performance experience within it. However, as immigrants they are experienced in communicating with Western audiences and conversant in Western ways of thinking about music. Immediately after completing the improvisation, each participant listened to a recording and looked at its visual representation, while describing the underlying thinking. The visual representation showed pitch contour and note length without reference to any notational system. A thematic analysis revealed eight main themes: Licks and Conventions describe how prelearned material and convention guided creation; Reaction, Forward Looking, and Repetition & Variety outline various processes that shape creation in the moment; and Aesthetics, Communication, and Emotion provide clues to the improvisers’ motivation behind choices. Interestingly, the use of prelearned patterns appear to facilitate improvisations in all the traditions represented. This and other identified strategies appearing cross-culturally may be shaped by shared cognitive constraints. These shared strategies may also facilitate understanding as educators broaden their curricula to multiple musical traditions.

<p>Architectural atmosphere is often characterised by loose descriptors which, rather than represent actual spatial qualities,depict an abstraction. Atmosphere is represented as an ephemeral quality that seems to naturally emanate from a givendesign. As a result, many refer to atmosphere as unable to be documented using traditional media. In response, thisthesis seeks to examine the architectural representation of atmosphere, and identify an effective method of codifyingand representing specific atmospheric qualities by examining the specific phenomenon of interruption, taking thecontemporary workplace as its site of investigation. Its larger aim, is the creation of a notational system that betterenables the design of atmosphere, specifically the design of atmospheres of interruption.</p>

Abstract Drawing on Jacques Derrida’s (1981) approach to deconstructing Platonic dichotomies, this article argues that any notational system is inherently structuring and should be subjected to deconstructive efforts. Further, my contention is that this deconstruction can be realized in how notation itself is used, in what I refer to as ‘deconstructive notation’. This article looks at how notation has been used by composers to deconstruct the categories of Western staff notation, opening up the ways in which music is studied as an invitation to all those engaged in notating music to make room in their work for deconstructive notational play.

In order to identify the authenticity of the industrial packaging, the solution to the current watermark technology is mainly to embed the same watermark capacity into each pixel value in the image, so that the watermark capacity is small, and the anti-distortion performance is not good. Data watermarking algorithm based on system and pixel difference. First divide the carrier image into non-overlapping sub-blocks, and calculate the pixel difference of each sub-block; introduce a hybrid system to obtain different bases. According to the pixel difference, the base selection rule is defined; considering the human visual characteristics, the pixel interval adaptive adjustment mechanism is designed to improve the coding technology and complete the watermark information embedding; finally, the watermark information extraction mechanism is established to restore the watermark. The experimental results show that compared with the current data watermarking algorithm, the proposed algorithm has ideal imperceptibility, as well as larger watermark capacity and lower distortion.

AbstractAs High Efficiency Video Coding (HEVC) is a worldwide popular video coding standard, the steganography of HEVC videos has gained more and more attention. Prediction unit (PU) is one of the most important innovative modules of HEVC; thus, PU partition mode-based steganography is becoming a novel branch of HEVC steganography. However, the embedding capacity of this kind of steganography is limited by the types of PU partition modes. To solve the problem, modified exploiting modification direction (EMD)-coded PU partition mode-based steganography is proposed in this paper, which can hide a secret digit in a (2n + x − 1)-ary notational system in a pair of PU partition modes and thus enlarging the capacity. Furthermore, two mapping patterns for PU partition modes are analyzed, and the one that performs the better is selected as the final mapping pattern. Firstly, 8 × 8- and 16 × 16-sized PU partition modes are recorded according to the optimal mapping pattern in the video encoding process. Then, PU partition modes are modified by using the proposed method to satisfy the requirement of secret information. Finally, the stego video can be obtained by re-encoding the video with the modified PU partition modes. Experimental results show that the embedding capacity can be significantly enlarged, and compared with the state-of-the-art work, the proposed method has much larger capacity while keeping high visual quality.

O domínio do Sistema de Escrita Alfabética (SEA) requer do sujeito cognoscente um eivado esforço conceitual, no sentido de perceber o que a escrita representa e como ela representa. Nós, adultos, por vezes, nos esquecemos de que a construção da base alfabética é um processo que exige estratégias, levantamento de hipóteses e superação paulatina dessas hipóteses, numa ação de monitoramento cognitivo. O domínio progressivo das propriedades do SEA depende da compreensão conceitual da escrita como objeto do conhecimento e da capacidade do professor alfabetizador em, por meio dessa compreensão, engendrar propostas que contemplem ações interventivo-mediadoras voltadas à problematização dos conhecimentos e concepções prévias dos aprendentes, fazendo-os construir novos esquemas e ampliar suas estruturas cognitivas. Entender a escrita como código ou como sistema notacional tem implicações didático-pedagógicas e epistêmicas, haja vista a prática alfabetizadora ser condicionada pela forma como se pensa a escrita e o papel que o sujeito tem nesse processo de apropriação. Defendemos um ensino explícito das propriedades do sistema alfabético aliado aos usos socioculturais da escrita e da leitura, por entendermos que desse ensino intencional resulta a ajuda (mediação) que o docente presta ao sujeito aprendente no percurso em busca de se tornar um proficiente leitor e produtor de textos, afinal, o fim basilar da alfabetização é levar o sujeito a ler e escrever com autonomia, uma vez que leitura e escrita são ferramentas de inserção sociocultural. Contudo, sem domínio das convenções da notação alfabética não se participa de situações de escrita e de leitura como tecnologias inclusivas.Palavras-chave: Sistema de escrita alfabética. Psicogênese da língua escrita. Ação interventivo-mediadora.Alphabetical writing system: problematizing a conceptual systemABSTRACTThe domain of the Alphabetic Writing System (AWS) requires the cognoscent subject to express a conceptual effort in order to perceive what writing represents and how it represents it. Us, adults, sometimes forget that the construction of the alphabetical base is a process that requires strategies, hypothesis collection and gradual overcoming of these hypotheses, in a cognitive monitoring action. The progressive mastery of SEA properties depends on the conceptual understanding of writing as an object of knowledge and the ability of the literacy teacher to, through this understanding, generate proposals that contemplate intervening-mediating actions aimed at the problematization of knowledge and conceptions of learners, making them construct new schemes and expand their cognitive structures. Understanding writing as a code or as a notational system has didactic-pedagogical and epistemic implications, since the literacy practice is conditioned by the way in which writing is thought and the role that the subject has in this process of appropriation. We advocate an explicit teaching of the properties of the alphabetic system combined with the sociocultural uses of writing and reading, since we understand that from this intentional teaching results the help (mediation) that the teacher gives to the learner in the course in order to become a proficient reader and producer of texts, after all, the basic aim of literacy is to lead the subject to read and write with autonomy, since reading and writing are tools of socio-cultural insertion. However, without mastery of the conventions of alphabetic notation, writing and reading situations are not included as inclusive technologies.Keywords: Alphabetical writing system. Psychogenesis of written language. Interventional-mediating action.Sistema de escrita alfabética: problematizando un sistema conceptualRESUMENEl dominio del Sistema de Escritura Alfabética (SEA) requiere del sujeto cognoscente un eivado esfuerzo conceptual, en el sentido de percibir lo que la escritura representa y cómo ella representa.
