Summer Sprite for Orchestra

Summer Sprite for Orchestra was completed in December, 2004. The piece originated from a singular encounter with little angels at Chang-Kyung Palace, which is the oldest and the most beautiful palace in Korea, and where the kings of the Chosun Dynasty (1393-1897) lived. This encounter was in the summer of 2002. I certainly could not prove that those angels I met were real. Possibly they were the reflection of drops of water after a sudden shower on that summer day. However, I definitely remember that short, unforgettable, and mysterious moment and the angels' beautiful dance-like celebration. Summer Sprite is based on these special memories and the encounter with the little angels that summer. Summer Sprite consists of 3 movements: "Greeting," "Encounter," and "Celebration." These follow the course of my encounter with the little angels. In Summer Sprite, I wished to describe the image of the angels as well as the progression of greeting, encounter, and celebration with them. The moods that follow in Summer Sprite are by turns lyrical, poetic, fantastic, mysterious, and dream-like. In each movement, I describe the meeting of angels and composer through the use of the soloists -- violin (sometimes viola) and cello. As suggested by the subtitle of the first movement, "Greeting" portrays the moment when a surprised I met the angels. It begins with tam-tam, marimba, harp, and piano and sets a mysterious and dark mood. The second movement, "Encounter," is shorter than the first movement. This movement provides a more tranquil mood as well as more unique timbres resulting from the use of mutes and special instruments (English horn, harp, crotales, suspended cymbal, and celesta). The delicate expression of the percussion is particularly important in establishing the static mood of this movement . The last movement, °?Celebration,°± is bright and energetic. It is also the longest. Here, I require the most delicate changes of dynamics and tempo, the most vigorous harmonies, and the fastest rhythmic figures, as well as the most independent, lyrical, and poetic melodies. For bright orchestral tone color, I used various kinds of percussion such as timpani, xylophone, marimba, vibraphone, cymbals, side drum, tambourine, triangle, and bass drum. This last movement is divided rondo-like into five sections: The first (mm.1-3), second (mm.4 - rehearsal number 1), third (rehearsal numbers 2-4), fourth (rehearsal numbers 5-7), and fifth, (rehearsal numbers 8 -18). To sum up, Summer Sprite describes an unforgettable and mysterious moment in a my life. My intention was to portray this through a concerto-like framework. A model for this would be Brahms°Ø °?Double Concerto°± in A minor, op.102, in which the solo cello stands for my angel and the solo violin (sometimes solo viola) for me

Increasing ecological validity in studies of facial attractiveness : effects of motion and expression on attractiveness judgements

While our understanding of what makes a face attractive has been greatly furthered in recent decades, the stimuli used in much of the foregoing research (static images with neutral expressions) bear little resemblance to the faces with which we nonnally interact. In our social interactions, we frequently evaluate faces that move and are expressive, and thus, it is important to evaluate whether motion and expression influence ratings of attractiveness; this was the central aim of the experiments in this dissertation. Using static and dynamic stimuli with neutral or positive expression, the effects of motion and expression were also tested in combination with other factors known to be relevant to attractiveness judgements: personality attributions, sex-typicality and cultural influence. In general, the results from this set of experiments show that judgements of moving, expressive stimuli do differ, sometimes radically, from judgements made of more traditional types of stimuli. Motion and positive expression were both found to increase ratings of attractiveness reliably in most experiments, as well as across cultures, and in some instances, showed strong sex-specific effects. Intriguing sex differences were also found in personality trait ratings of the stimuli, particularly for male faces; while criteria for female faces remained relatively constant across all conditions, trait ratings associated with attractiveness for male faces were dependent on particular combinations of motion and expression. Finally, in line with previous research, cross-cultural experiments showed general agreement between Japanese and Caucasian raters, but also suggested slight, culture-specific differences in preferences for expression and motion. IV This set of experiments has integrated the factors of motion, expression, sextypicality, personality and cultural influence together in order to bring a greater degree of ecological validity into attractiveness studies. These findings offer major implications for researchers studying attractiveness, particularly that of males, and suggest that motion and expression are important dimensions that should be considered in future research while simultaneously placing a caution on the interpretation of findings made with static stimuli. Suggestions are also made for further research in light of the present finding

Data breach worries: a special report

Australian company’s recent acquisition of JobStreet’s assets raises the question of whether Malaysia is exposing its sensitive data to foreign companies. While mergers and acquisitions (M&As) are part of doing business and cannot be avoided or controlled by the authorities, are Malaysian companies inevitably exposing data deemed sensitive to foreigners? To what extent are these companies and even government agencies revealing strategic information by allowing them access to data that carry financial, economic and security value

Microeconomic models of intra-household activity time allocation

The primary purpose of this research is to analyze theoretically the group decisionmaking process leading to the allocation of activity time and the consumption of goods, with particular emphasis in the households. Each household is characterized as a group of individuals making joint decisions about their activity participations, alternative activity time allocations and consumption of various goods, such as independent and joint activity time allocations as well as private and shared consumption patterns. We firstly explore why individual-based models are not realistic in multi-person households, and secondly, we summarize various intra-household activity time allocation models based on different decision-making processes. All models are presented under microeconomic principle of utility maximization to represent the economic behavior of the households

Incorporating differences in marginal utilities of time across activities in a time allocation model

Most existing activity time allocation models assume that individuals allocate their time to different activities over a period in such a way that the marginal utilities of time across activities are equal. Their argument is that, if not equal, an individual is free to allocate more time to those activities whose marginal utilities of time are higher and, finally allocates the optimal time to each activity with equal marginal utility. However, such an ideal situation may not always prevail in reality, especially when an individual is under income constraint and/or under intense time pressure. In order to incorporate such differences in marginal utilities of time across activities, we enrich the traditional activity time allocation model by explicitly including income constraint and by adding marginal extension activity choice model. As an application, the developed integrated model is used to estimate the value of activity time during weekends in Tokyo. The results are encouraging in that they forecast the individual time allocation more accurately and estimate realistically the value of activity time for each activity in a set of different activities than do by existing traditional models

Robust Linear Discriminant Analysis with Highest Breakdown Point Estimator

Linear Discriminant Analysis (LDA) is a supervised classification technique concerned with the relationship between a categorical variable and a set of interrelated variables.The main objective of LDA is to create a rule to distinguish between populations and allocating future observations to previously defined populations.The LDA yields optimal discriminant rule between two or more groups under the assumptions of normality and homoscedasticity.Nevertheless, the classical estimates, sample mean and sample covariance matrix, are highly affected when the ideal conditions are violated.To abate these problems, a new robust LDA rule using high breakdown point estimators has been proposed in this article.A winsorized approach used to estimate the location measure while the multiplication of Spearman’s rho and the rescaled median absolute deviation were used to estimate the scatter measure to replace the sample mean and sample covariance matrix, respectively.Simulation and real data study were conducted to evaluate the performance of the proposed model measured in terms of misclassification error rates.The computational results showed that the proposed LDA is always better than the classical LDA and were comparable with the existing robust LDAs
