Journal ArticleDOI
TL;DR: The studies summarized in this volume indicate many population groups have similar potentials for growth in major body dimensions, and the narrower range of means among European than among African groups that range from "tribal" to well-off indicates the range of variation in growth would be reduced greatly if the environmental circumstances allowed.
Abstract: This is a very large compilation of growth data with an extremely wide coverage of population groups, many of which will be completely unknown to all but the professional ethnographer. There is, however, a disappointingly narrow coverage of variables (length, weight, body widths, circumferences and proportions, skinfold thicknesses, and maturity). Many of the findings are relevant to an important question: should one set of growth reference data be used throughout the world, thus allowing ready comparability between groups, or should there be separate sets for each major racial group or even a multitude of local sets? The studies summarized in this volume indicate many population groups have similar potentials for growth in major body dimensions. For example, the narrower range of means among European than among African groups that range from "tribal" to well-off indicates the range of variation in growth would be reduced greatly if the environmental circumstances allowed

TL;DR: The nature of metal complexes of heterocyclic thiosemicarbazones reported in the literature through 1989 have been reviewed with an emphasis on variations in stoichiometry and stereochemistry as discussed by the authors.
Abstract: The nature of metal complexes of heterocyclic thiosemicarbazones reported in the literature through 1989 have been reviewed with an emphasis on variations in stoichiometry and stereochemistry. A brief introduction is followed by a survey of the biological activity of the uncomplexed thiosemicarbazones. Next is a section on the chemical nature of thiosemicarbazones including a discussion of preparative methods, modes of coordination and isomerism. This is followed by a discussion of structural information and biological activity of the iron(III), iron(II), copper(II), cobalt(III), cobalt(II) and nickel(II) complexes of heterocyclic thiosemicarbazones. Short sections on the biological activity of other chelating thiosemicarbazones and metal complexes are also included.
