Exploring Emptiness: An Investigation of MA and MU in My Sonic Composition Practice
No full textThe commentary investigates Japanese aesthetics of space, silence and emptiness - ma and mu - that informed my compositional practice during the research period 2012 - 2015. The portfolio comprises text compositions and sound installations in which forms of micro events and sustained events are employed. Throughout, the emphasis is on my personal engagement with, and manifestation of emptiness that concerns a particular model of listening and perception.
Chapter 1 discusses six primary research areas: ma and mu, material, text, form, listening and perception. Firstly, I introduce ma and mu by examining noh culture and Zeami's teaching of senu hima (where there is no-action) in the context of my personal approaches to music. The following subjects are then used to contextualise my PhD practice by means of examples from various composers and visual artists. Here, these particular and enigmatic concepts are explored through Japanese art as well as Western contemporary works by Alvin Lucier, Eliane Radigue and those of the Wandelweiser collective.
Part 2 provides contextual commentaries on selected compositions from the portfolio that mostly articulate my aesthetics in relation to the topics covered in Chapter 1. koso koso addresses my methodologies to investigate the essence of senu hima, followed by treow that discusses my approach to materials and the importance of space. I move on to grade two and grade two extended in order to examine text scores, and then, look into Espèces d'espaces 03 and 04 as examples of musical forms that I employ.
Finally, listening and perception are investigated through the compositions gnome and con.de.structuring. Throughout, I describe how my works explore emptiness as a result of my particular emphasis on listening over composing
The Effectiveness of Forecasting Methods Using Multiple Information Variables
No full textThis paper examines the effectiveness of forecasting methods using multiple information variables in forecasting the rate of changes in the consumer price index (CPI) and real GDP in Japan, and investigates the background of forecast performance improvement and its limitations. We first examine the performance of forecasts that use individual information variables as well as forecasts that use multiple information variables. The results show that no single variable improves forecasts in all periods for either CPI or GDP, but combining the information from individual forecasts can lead to a stable forecast performance. Next, to explore the backdrop to these improvements in forecast performance, we decompose and analyze the forecast error of forecast combinations using a simple mean. We discover that the irregular movements of forecast errors generally cancel each other out, which in turn leads to a reduction in errors. At the same time, the effect of reducing forecast errors rapidly diminishes with the addition of variables, and we verify that forecast performance stops improving after two to four variables are added. For this reason, it is necessary to consider both the performance of original forecast series that comprise the combination, and the combination of variables that best reduces the correlation among forecast error series to obtain the optimal combination of series.

Thinking without Language
No full textIt is not possible to know directly what animals think because they cannot speak to us about it. We must therefore infer their thought from their behavior. From a behavioral point of view, thinking is a problem solving behavior itself. What is the nature of animal thought without language? As an answer to this question, the behavior of identifying a stimulus has been investigated in matching-to-sample experiments. Pigeons can make a same-different judgement for a single stimulus in the transfer test of a matching-to-sample performance, but they cannot make the same-different judgement for the relation between stimuli in a pair. According to Premack (1983), a language trained chimpanzee (Sarah) was capable of doing this kind of same-different judgement while chimpanzees without language training were not. The author does not approve of his view that the success of relational judgement is due to language. Because animals may perceive a pair of stimuli as a symmetric or asymmetric pattern instead of as a same-different relation. Furthermore, he reported that Sarah was capable of solving analogy of stimulus relations (A/A'=B/?) while chimpanzees without language training were not. But these problems may be solved by functional generalization; that is, lower animals, such as rats and pigeons, may be able to solve such problems as well. Therefore, as far as the same-different judgement is concerned, qualitative difference can be found extremely little between primates and non primates in the previous data
