The U.S. music market is a lucrative market for many foreign musicians due to its sheer size and it continues to play a leading role in the world music industry. However, it is a challenge to gain entry into that market and an even greater challenge to achieve success and fame within it. In fact, changes in the media paradigm have allowed for musicians to be able to independently produce their own songs and promote them globally. Some scholars address that the media paradigm shifting from traditional outlets to new outlets gives a chance to bypass traditional gatekeepers when entering the U.S. music market. Based on this scenario, this article examined two songs from Korean singer, Psy: Gangnam Style and Gentleman as a single case study. Utilizing Google Trends as a source of information, this study examined how each song's recognition among American music fans was different based on radio spins on Top 40 commercial radio stations. This article sheds new light on radio, which has been neglected due to the media paradigm shift, and presents how radio programmers are part of a complicated gatekeeping process which ultimately decides which songs are to gain popularity.

The concept of interfaith harmony is one of the key issues for discussion in this contemporary world. It has multifaceted implications that range from pedagogical realms to global policy making. Here we focus on the basic concepts of interfaith harmony from Sikh and Cao Dai perspectives in order to address their viewpoints in regard to promoting culture of Peace and Understanding. Although these religions are new as compared to the existing living religions of the world, they found their new identity in the history of world religions for their unique concepts of interfaith harmony. In this article, the concept of interfaith harmony has been analyzed from two perspectives such as theological and socio-historical. For a systematic understanding of the subject matter, it has been categorized into three subpoints; unity of God, unity of religions and unity of humanity. Methodologically, the qualitative methodological framework of the proposed research is descriptive in nature. Thus, the present research has been primarily conducted by using secondary sources, although the crucial information is collected from primary sources such as the sacred texts of Sikhism and Caodaism. Since this study is done considering the social, political and religious contexts of India and Vietnam, it can contribute to the understanding of the nature of interfaith harmony in South and South-East Asia.

Advanced Life Support Systems (ALSS) are being studied to support human life during long-duration space missions. ALSS can be categorized into four subsystems: Crew, Biomass Production, Food Processing and Nutrition, Waste Processing and Resource Recovery. The System Studies and Modeling (SSM) team of New Jersey-NASA Specialized Center of Research and Training (NJ-NSCORT) has facilitated and conducted analyses of ALSS to address systems level issues. The underlying concept of the SSM work is to enable the effective utilization of information to aid in planning, analysis, design, management, and operation of ALSS and their components. Analytical tools and computer models for ALSS analyses have been developed and implemented for value-added information processing. The results of analyses have been delivered through the Internet for effective communication within the advanced life support (ALS) community. Several modeling paradigms have been explored by developing tools for use in systems analysis. They include object-oriented approach for top-level models, procedural approach for process-level models, and application of commercially available modeling tools such as MATLAB$\^$(R)//Simulink$\^$(R)/. Every paradigm has its particular applicability for the purpose of modeling work. An overview is presented of the systems studies and modeling work conducted by the NJ-NSCORT SSM team in its efforts to provide systems analysis capabilities to the ALS community. The experience gained and the analytical tools developed from this work can be extended to solving problems encountered in general agriculture.
