Tonal Hierarchy

Despite the plethora of research on the role of tonality and meter in music perception, there is little work on how these fundamental properties function together. The most basic question is whether the two hierarchical structures are correlated – that is, do metrically stable positions in the measure preferentially feature tonally stable pitches, and do tonally stable pitches occur more often than not at metrically stable locations? To answer this question, we analyzed a corpus of compositions by Bach, Mozart, Beethoven, and Chopin, tabulating the frequency of occurrence of each of the 12 pitch classes at all possible temporal positions in the bar. There was a reliable relation between the tonal and metric hierarchies, such that tonally stable pitch classes and metrically stable temporal positions co-occurred beyond their simple joint probability. Further, the pitch class distribution at stable metric temporal positions agreed more with the tonal hierarchy than at less metrically stable locations. This tonal-metric hierarchy was largely consistent across composers, time signatures, and modes. The existence, profile, and constancy of the tonal-metric hierarchy is relevant to several areas of music cognition research, including pitch-time integration, statistical learning, and global effects of tonality.

Embodiment Theory

In this paper, we present recent and on-going research in the field of embodied music cognition, with a focus on studies conducted at IPEM, the research laboratory in systematic musicology at Ghent University, Belgium. Attention is devoted to encoding/decoding principles underlying musical expressiveness, synchronization and entrainment, and action-based effects on music perception. The discussed empirical findings demonstrate that embodiment is only one component in an interconnected network of sensory, motor, affective, and cognitive systems involved in music perception. Currently, these findings drive embodiment theory towards a more dynamical approach in which the interaction between various internal processes and the external environment are of central importance. <br />

Lock In

We offer a path-centric theory of emerging technology and organizing that addresses a basic question. When does emerging technology lead to transformative change? A path-centric perspective on technology focuses on the patterns of actions afforded by technology in use. We identify performing and patterning as self-reinforcing mechanisms that shape patterns of action in the domain of emerging technology and organizing. We use a dynamic simulation to show that performing and patterning can lead to a wide range of trajectories, from lock-in to transformation, depending on how emerging technology in use influences the pattern of action. When emerging technologies afford new actions that can be flexibly recombined to generate new paths, decisive transformative effects are more likely. By themselves, new affordances are not likely to generate transformation. We illustrate this theory with examples from the practice of pharmaceutical drug discovery. The path-centric perspective offers a new way to think about generativity and the role of affordances in organizing.

The Given

The nations take various strategies in exposure to different developments and phenomena and impact on foreign and internal policies of countries in international scene proportional to their internal and external conditions and rivals and at international arena. What US implemented after September 11 Event and targeted accusation finger toward Taliban and Al-Qaeda in Afghanistan is deemed as a type of strategy that has occurred in created nostalgic climate together with hasty decision making and negligence to domestic issues in Afghan Community while their output was to take different and even paradoxical strategies in this crisis-stricken region since 1980s. In this article that has been written in order to analyze US Post September- 11 Strategies in Afghanistan this basic question will be answered that how changes in US macro policies influenced in orientation of diplomacy of this country and why this country has adapted different policies in occupation of Afghanistan. Afterwards, it is deduced according to the given findings from librarian data collection method that the constant changes in US strategy in Afghanistan were due to overlooking of domestic issues and historic, ethnic, cultural, political, and ideological complexities of this country that has resulted in degradation of US position in world scene and its failure in suppression of Taliban.This article has been excerpted from my PhD treatise under title of ‘The role of United States in the regional crisis (e.g. Afghan and Iraqi crises) and the rise of revolutionary and radicalism on the emergence of international terrorism’.

This research tackles the role of communication in social marketing of child issues in the Sudan, a case study on the ministry of Social Development in Khartoum state. The purpose of this research is to recognize the communication role done by General Administration of  Information and Social Awareness of  the ministry of  Social Development in marketing the programs of social campaigns of the Sudanese child represented in social patronage, sponsorship and supporting and protection, include the specific social, economic and political aspects, as health, education, providing security and settlement. The research tried to answer a number of questions, one of them is a basic question. What is the number and size of information campaigns implemented at the period from August 2019 to August 2020? The researcher used the descriptive methodology besides the methodology of status study. And the researcher depends on questionnaire, the (systemized) interview form, (not systemized) interview form, and the simple observation . Findings: The research concluded to a number of findings, the most important of them are: 1.There is a malfunction in the efficiency of communication with the General Administration of Information and Social Awareness of the ministry.  The cause of this is lack of enough trained information cadre, and lack of enough money be specified to the campaign. 2.The subjects and Programs come within the campaign do not cover all sectors of children but concentrate on the children of hard circumstances. 3.The number of information campaigns implemented at the period from 2019 to 2020 are two: a campaign  on orphanages (Halima Al-Saadaya) and a campaign to patronize the children of streets (who lost the family caring).

The central role of the body in producing music is hardly debatable. Likewise, the body has always played at least an implicit role in music theory, but has only been raised as a factor in music analysis relatively recently. In this essay I present a brief update of the body in music analysis via case studies, situated in the disciplines of music theory and music cognition, broadly construed. This current trajectory is part of a broader shift away from the musical score as the sole focus for analysis, which admittedly—though, in my view, delightfully—raises a host of challenging epistemological questions surrounding the interaction of performer (production) and listener (perception). While the concomitant research methodologies and technologies may be unfamiliar to scholars trained in humanities disciplines, I advocate for a full embrace of these approaches, either by individual researchers or in the form of cross-disciplinary collaboration.

Oral Transmission

In this commentary, I would like to add a few of our own, still unpublished, empirical observations concerning the possible role of absolute pitch memory (APM) in the oral transmission of folksongs. This empirical data poses some questions on the likelihood of the observed inter-recording tonic pitch consistency of Olthof, Janssen &amp; Honing (2015) and how these could come about. Based on simulations of absolute pitch class of tonics during oral transmission of folk songs, I argue that the interplay of melodic range and vocal range might actually be the main reason for the observed non-uniformity, in contrast to the conclusions presented in Olthof et al. (2015). However, this does not invalidate the therein presented evidence, but makes the case more puzzling, consequently calling for more empirical research on the interaction of melodic and vocal range and latent APM as well as for more detailed modeling of oral transmission of folk songs.

The paper describes the role of geomechanical processes and phenomena in the development and manifestation of hazardous situations in the development of mineral deposits, threatening the working personnel and the surrounding population. The studies of the Ural Scientific School of geomechanics functioning in the Institute of Mining of Ural Branch of RAS have established that the basis for the formation of hazardous geomechanical processes and phenomena are the fundamental properties of the rock mass - hierarchical blocking and constant mobility caused by the recent geodynamical movements. The constant mobility of hierarchical block medium of rock mass under the influence of trend and short-term recent geodynamical movements gives rise to the phenomenon of the secondary structuring. The recent geodynamical movements concentrate at the borders of the secondary structures and result in the deformations exceeding by 2 - 5 times the intrablock and integral deformations and representing the main source of the hazardous impact on the mining objects and on the surrounding population. The technology of the geological environment diagnostics for the forecast of hazardous mining situations is aimed at the identification of the boundary zones of secondary structures, the estimation of the hazard level of deformation processes and the adoption of proactive measures.

In this paper, a number of recently proposed implicit and explicit composite time integration schemes are reviewed and critically evaluated. To give suitable guidelines of using them in practical transient analyses of structural problems, numerical performances of these schemes are compared through illustrative examples. Meaningful insights into computational aspects of the composite schemes are also provided. In the discussion, the role of the splitting ratio of the recent composite schemes is also investigated through a different point of view, and similarities and differences of various composite schemes are also studied. It is shown that the explicit composite scheme proposed recently by the authors can noticeably increase the efficiency and the accuracy of linear and nonlinear transient analyses when compared with other well-known composite schemes.
