Globalization of business is bringing in seasoned competitors from the developed countries into the growing markets of the Third World. Consequently, the survival of local enterprises and entrepreneurs is being threatened. Third World managers need to develop a global mindset in order to take advantage of the changed new world order in business. Elucidates the notion of global mindset and examines some typical management training methods and techniques for their adequacy to develop this orientation among Third World managers. Discusses relevant cultural, organizational and macro‐environmental issues. Presents conclusions and recommendations for Third World contexts in respect of Western training methods and business school curricula for broadening the managerial horizons in this era of globalized business.

Abstract. It is proved that Epstein's zeta-function ζ Q (s) related to a positive definite integral binary quadratic form has a zero 1 2 + iγ with T ≤ γ ≤ T + T 5/11+ε for sufficiently large positive numbers T . This improves a classical result of H.

We investigate the solvability of the Diophantine equation in the title, where d > 1 is a square-free integer, p, q are distinct odd primes and x, y, a, b are unknown positive integers with gcd(x, y) = 1. We describe all the integer solutions of this equation, and then use the main finding to deduce some results concerning the integers solutions of some of its variants. The methods adopted here are elementary in nature and are primarily based on the existence of the primitive divisors of certain Lehmer numbers.
