Musical Tradition in Megalithic Site of Indonesian Gunung Padang?

The paper reports a possibilities of musical traditions of ancient civilization who built the sites discovered in Gunung Padang, West Java, Indonesia. Particular group of the stones in the megalithic site happens to have relatively high frequency that might have correspondence with standard western musical scale. From the samples recorded at the site, we do the power spectral analysis to have the dominant frequency within the audio and mapped the result to MIDI numbers. We showed that the obtained four notes interestingly have particular places in modern musical scale

Evolution of Consumers’ Preferences due to Innovation

The integration process between evolutionary approach and conventional economic analysis is very essential for the next development of economic studies, especially in the fundamental concepts of modern economics: supply and demand analysis. In this presentation, we use the concept of meme to explore evolution of demand. This study offers an evolutionary model of demand, which views utility as a function of the distance between the two types of sequences of memes (memeplex), which represent economic product and consumer preference. It is very different from the conventional approach of demand, which only views utility as a function of quantity. This modification provides an opportunity to see innovation and transformation of consumer preferences in the demand perspective. Innovation is seen as a change in sequence of memes in economic products, while the transformation of consumer behavior is defined as a change in the aligning memes of consumer preference. Demand quantity is the result of the selection process. This model produces some interesting characteristics, such as: (i) quantitative and qualitative properties of evolution of demand, (ii) relationship between consumer behavior and properties of evolution of demand that occurred and (iii) power law on the distribution of product lifetime. At the end we show the improvement of utility function, in the concept of meme, might create a new landscape for the further development of economics

Historical Relative Performance Index over Interconnectedness of Badminton Athletes

The paper proposes the Historical Relative Performance Index in order to quantitatively extract information in the scores hit in the sets of head-to-head game in badminton tournaments. The index is treated as the weights of the directed networks built between competing athletes. The paper also proposes the way to build the fully connected network based on the empirically found network in order to have relative index between athletes that have never nor will be met in series of games. Some further directions as well as implementation to small amount of data is described for advanced analysis

CHALLENGES IN PERSPECTIVE ON CORPORATE STRATEGY

There are several issues in corporate strategies such as the impact of corporate to performance, the cause and limit of performance, development management and external environment of corporation. This study aims to discuss those issues based on literature review. It is found out that corporate impact to performance is non-neglectable, event though the degree of impact is still unknown. Experience managerial service are important for company to achieve its performance and to achieve its performance, corporation may choose between two approaches incremental and comprehensive, each approach has its own benefits and drawbacks. As a result, it should be aligned with internal and external condition of the corporation and the cost and benefit aspects. External aspect of the corporation in this particular, macroeconomic uncertainty, will influence the strategy of corporation even when the firm only play in local market. In addition, national economic development will impact on how corporation build its strategy.Keywords: corporate strategy, corporate-impact, corporate performance
