The opening decades of the twentieth century saw a passing fashion for “Aztec” dancing in the vaudeville theaters of the United States. Russian classical dancers Kosloff and Fokine tapped the orientalist currents of the Ballets Russes, adopting the Aztec as superficial signs of the American. Conversely, works by Shawn and film director Cecil B. DeMille, which served as points of reference for the Russians, represented a continuation of equally orientalist attitudes toward Mexico's past, forged during the realization of the United States’ policy of Manifest Destiny. The emergence of a cadre of trained dancers from Mexico, trained by students of Kosloff and Shawn, would bring a distinctively different perspective on the presentation of their heritage to the dance stage, one that was no longer based in the imagination of an expansionist America.

Southeast Asia in United States policy fell from a region of high priority during the Vietnam war to become, after the fall of Indochina, an area of relatively minor interest. For the United States, Southeast Asia evoked memories of misperception, intensified over-commitment, and simplistic assumptions that characterized the American effort to defeat local Vietnamese national communism. Since the formulation of the Nixon doctrine of disengagement in 1969, United States policy towards Southeast Asia has been undergoing a process of long-term readjustment in recognition of the exaggerated significance that the region had assumed in American thinking. The fall of Saigon in April 1975 was a major stimulus to this readjustment as it gave the Americans compelling reasons to anticipate a reassertion of Soviet influence in the region. Successive American administrations attempted to place the region in a wider global context to avoid the dangers of extreme reaction to local national communism while developing the flexibility to coordinate a response to the Soviet Union at a global level. The main concern of American policy was to remove the basis for direct United States involvement in the region in a way that would satisfy post-Vietnam war public and congressional opinion and the demands of strategic planners for greater freedom of manoeuvre against the Soviet Union.

AbstractOne of the critical issues in education today is how to help all students to maximize their fullest potential. Achieving this goal seems to be difficult for many people who come from culturally and linguistically diverse (CLD) backgrounds. At all levels, they endure direct and indirect disenfranchisements, disadvantages, and disillusionments, especially if they learn differently, are racially different, demonstrate different behavioral patterns, have different personal idiosyncrasies, or come from different countries. Despite these apparent impediments, Asians are viewed by many as “model” minorities when compared to African Americans, Latinos, and Native Americans. This view has continued to affect how Asians view themselves and how the society as a whole views them. Coming originally from Nigeria to the United States, I have had myriad interactions with Asians as student, professor, scholar, leader, and professional. In this article, I share my experiences with Asians and how these experiences have exposed multicultural realities and myths.
