Statistical and microscopic studies of ethnographic Australian Aboriginal stone tools reveal patterns which correlate significantly with the known uses, techniques of manufacture, and native classification of these tools. Statistically, the most significant correlation occurs between the angle of the working edge of the tool and the classification and function of the tool. Steep-edge flakes are classified as purpunpa and serve as woodworking scrapers, while flakes with acute edge-angles are classed as tjimari and are used as knives for cutting skin and tendons. Microscopic study has further revealed that woodworking scrapers show a distinctive pattern of use-wear. Some trial comparisons are also attempted between ethnographic Aboriginal woodworking scrapers and Quina-type scrapers of Bordes' Quina-Ferrassie facies of the Mousterian in order to suggest the value of comparing ethnographically known tools with archaeological specimens.

This study examines the personal backgrounds, business objectives, modes of operation, and degrees of success of Korean greengrocers and Hispanic grocery store owners in the New York metropolitan area. In so doing, the study seeks to uncover factors that may condition differential business performance among all groups of imigrant entrepreneurs, including Koreans and Hispanics. A survey of 40 Korean and 72 Hispanic businesspersons revealed that both groups tended to work equally hard in terms of the number of hours worked in the business per week. However, the Korean greengrocers were found to be more successful in terms of the profitability and cash flow generated by their stores. The primary reason for this difference appeared to be the fact that Korean business practices were guided mainly by the profit motive, while those of Hispanics were influenced by such nonmonetary concerns as independence and personal satisfaction. These findings led the authors to conclude that there are alternative measures of material “success” and that the equally strong efforts of both groups of immigrant entrepreneurs have resulted in two different, but important kinds of success. Certain policy implications of this conclusion could lead to further immigrant participation in small business.
