Declining fertility in many Asian countries is leading to concern about its implications for support and care of the elderly. This study examines variations in intergenerational support by family size, family composition and location of children in Vietnam based on recent regional surveys in the north and south of the country. Results confirm the central role of children in providing material a...

Language learning and language use play central roles in problem-solving. It is argued here that a r ig idly bui l t in language w i l l not serve the needs of problem-solving. To use language as significantly as in human problemsolving it is necessary to design language processors specially suited to the task. The procesBoi should use language as a medium for describing situations so that thei...
The rst part of this diploma thesis deals with the topic of nding equivalent norms and characterizations for vector-valued Besov and Triebel-Lizorkin spaces Bs p,q(E) and F s p,q(E). We will deduce general criteria by transferring and extending a theorem of Bui, Paluszy«ski and Taibleson from the scalar to the vector-valued case. By using special norms and characterizations we will derive neces...
Mound-building Fmmica ants may be important biotic factors within prairie restorations because mounds found in virgin prairies can exist for decades, with densities up to 1,148 mounds/ha (465 mounds/acre). Research on the effects of Formica ant mounds on a virgin and an adjacent restored prairie (treatments) was established in 2003 near Olathe, Kansas; and it was expected that percent soil mois...
The specularity calculation of the Phong shading method is reformulated to use the squared length of a difference vector in place of a dot product to characterize the closeness of the viewpoint to the specularity. The new formulation is easier to compute, using only a modest numbers of multiplications and additions, and is much better behaved numerically. Due to the better numerical properties,...
Complexes of the type (OCH2C(CH3)2CH2OB)2S2P(S)OR (where R=Me,Et,Pri,Bui,Ph,CH2Ph) have beensynthesized by the reactions of 2-chloro-1,3,2-dioxaborinanes and potassium salt of O-alkyl (O-aryl)trithiophosphates in 2:1 molar ratio in refluxing benzene. The product are formed as white or light yellowcoloured monomeric solid, soluble in common organic solvents and exhibit high sensitivity towardsat...
