(Dis‑)Harmony in movement: effects of musical dissonance on movement timing and form

While the origins of consonance and dissonance in terms of acoustics, psychoacoustics and physiology have been debated for centuries, their plausible effects on movement synchronization have largely been ignored. The present study aims to address this by investigating whether, and if so how, consonant/dissonant pitch intervals affect the spatiotemporal properties of regular reciprocal aiming movements. We compared movements synchronized either to consonant or to dissonant sounds, and showed that they were differently influenced by the degree of consonance of the sound presented. Interestingly, the difference was present after the sound stimulus was removed. In this case, the performance measured after consonant sound exposure was found to be more stable and accurate, with a higher percentage of information/movement coupling (tau-coupling) and a higher degree of movement circularity when compared to performance measured after the exposure to dissonant sounds. We infer that the neural resonance representing consonant tones leads to finer perception/action coupling which in turn may help explain the prevailing preference for these types of tones.

A hybrid harmony search with arithmetic crossover operation for economic dispatch

Economic dispatch (ED) problems often exhibit non-linear, non-convex characteristics due to the valve point effects. Further, various constraints and factors, such as prohibited operation zones, ramp rate limits and security constraints imposed by the generating units, and power loss in transmission make it even more challenging to obtain the global optimum using conventional mathematical methods. Meta-heuristic approaches are capable of solving non-linear, non-continuous and non-convex problems effectively as they impose no requirements on the optimization problems. However, most methods reported so far mainly focus on a specific type of ED problems, such as static or dynamic ED problems. This paper proposes a hybrid harmony search with arithmetic crossover operation, namely ACHS, for solving five different types of ED problems, including static ED with valve point effects, ED with prohibited operating zones, ED considering multiple fuel cells, combined heat and power ED, and dynamic ED. In this proposed ACHS, the global best information and arithmetic crossover are used to update the newly generated solution and speed up the convergence, which contributes to the algorithm exploitation capability. To balance the exploitation and exploration capabilities, the opposition based learning (OBL) strategy is employed to enhance the diversity of solutions. Further, four commonly used crossover operators are also investigated, and the arithmetic crossover shows its efficiency than the others when they are incorporated into HS. To make a comprehensive study on its scalability, ACHS is first tested on a group of benchmark functions with a 100 dimensions and compared with several state-of-the-art methods. Then it is used to solve seven different ED cases and compared with the results reported in literatures. All the results confirm the superiority of the ACHS for different optimization problems.

An efficient harmony search with new pitch adjustment for dynamic economic dispatch

A simple yet efficient harmony search (HS) method with a new pitch adjustment rule (NPAHS) is proposed for dynamic economic dispatch (DED) of electrical power systems, a large-scale non-linear real time optimization problem imposed by a number of complex constraints. The new pitch adjustment rule is based on the perturbation information and the mean value of the harmony memory, which is simple to implement and helps to enhance solution quality and convergence speed. A new constraint handling technique is also developed to effectively handle various constraints in the DED problem, and the violation of ramp rate limits between the first and last scheduling intervals that is often ignored by existing approaches for DED problems is effectively eliminated. To validate the effectiveness, the NPAHS is first tested on 10 popular benchmark functions with 100 dimensions, in comparison with four HS variants and five state-of-the-art evolutionary algorithms. Then, NPAHS is used to solve three 24-h DED systems with 5, 15 and 54 units, which consider the valve point effects, transmission loss, emission and prohibited operating zones. Simulation results on all these systems show the scalability and superiority of the proposed NPAHS on various large scale problems.

VELS versus CSF : replacement, conflict or harmony?

Sometimes VELS (Victorian Essential Learning Standards) is confusing. Part of the problem is that it is available only on-line as a web-browse-able collection of internet web pages. It is broadly true that the mathematics curriculum described by the Mathematics VELS is equivalent to curriculum described by the Mathematics CSF (Curriculum and Standards Framework).

Harmony in and between aesthetic experience and moral experience

The thesis finds that the notion of harmony has been integral to the concepts of beauty and goodness from the earliest times, in Eastern and Western philosophy. It also argues that the experience of beauty and the experience of goodness are related through the human propensity to avoid disorder.

Kevin Rudd and harmony

At a major speech at the Brookings Institution in Washington DC on March 31, 2008, Rudd indicated a new direction in Australian foreign policy concerning China. He focused on the concept of 'harmony', recognizing the key importance of China's role in a 'harmonious World 'as a' responsible stakeholder. '
Rudd declared that he looked to China's taking a vital role in the World 'in strengthening the global and regional rule-based order'. He has also highlighted the importance of treating China as a friend with much common ground but with whom honest, straight talk was a vital factor in the relationship.
I want to explore and explain the development and significance of Rudd's new approach to the concept of harmony and rule based order. I want to suggest that Rudd has pioneered a new direction in Australia's policies toward China. Rudd focuses on the ancient and developing concept of harmony into a rule-based order that is necessary to building a harmonious world.

Intercultural harmony and understanding in the city of Whittlesea

The City of Whittlesea is one of the most ethnically diverse urban areas in Melbourne that attracts settlers, often humanitarian migrants from countries in the Horn of Africa and the Middle East. With settlers arriving from a broader range of countries than ever before, increasing ethnic as well as ethno-religious diversity presents opportunities for local government to address intercultural harmony and understanding but also significant challenges. This paper reports the findings of fieldwork conducted in 2009 among residents focusing on attitudes towards ethnic diversity and evaluations of the capacity of local government to promote intercultural harmony and understanding. The results suggest that if local government is to be inclusive and gain the confidence and trust of residents necessary to foster empowering partnerships, political spaces that facilitate interactions between long-term residents, new residents, elected leaders and council officers must be facilitated. Such initiatives will contribute to strengthening programs and policies being developed by local government that aim to address discrimination experienced by ethnic minorities and encourage greater acceptance of cultural diversity among the broader community in ways that move beyond measurable outcomes.
