Archaeology and World-Systems Theory

Archaeology has tremendous potential for developing world-systems approaches to non-Western and noncapitalist societies because it has the ability to both explore non-Western and noncapitalist societies with the sophistication of anthropology and to explore societies in existence long before the capitalist world-system began to evolve. I suggest that sociologists stand to gain by learning about non-Western and noncapitalist societies, particularly as they are understood by archaeologists. World-systems theory provides a common framework within which archaeologists and sociologists can both work. This article explores recent work in world-systems archaeology that sociologists might find particularly valuable.     

Category Distinguishability and Observer Agreement

It is common in the medical, biological, and social sciences for the categories into which an object is classified not to have a fully objective definition. Theoretically speaking the categories are therefore not completely distinguishable. The practical extent of their distinguishability can be measured when two expert observers classify the same sample of objects. It is shown, under reasonable assumptions, that the matrix of joint classification probabilities is quasi-symmetric, and that the symmetric matrix component is non-negative definite. The degree of distinguishability between two categories is defined and is used to give a measure of overall category distinguishability. It is argued that the kappa measure of observer agreement is unsatisfactory as a measure of overall category distinguishability.     

Studies in MBO effectiveness.

Management by objectives (MBO) is a popular management approach the efficacy of which has been seriously questioned recently. I have analyzed 185 studies for the effects of MBO on employee productivity and/or job satisfaction. Research support for MBO was found to be inversely related to the degree of research design sophistication. Although the five well-controlled experiments leaned toward finding MBO to be ineffective, it appears a contingency approach to MBO is more appropriate than a definitive affirmation or rejection of MBO effectiveness.     

The Child Well-Being Scales: a field trial.

The Child Well-Being Scales [Magura and Moses 1986] were developed to evaluate programs of child welfare services. Although appealing in format, the scales have lacked adequate validation. For the field trial reported here, 17 of the scales were extracted and used to form measures of physical and psychological care of children. A comparison between families identified as neglectful and low-income control families yielded differences in the predicted direction. The composite indices showed good internal consistency. The concurrent validity of this segment of the scales was supported. The scales yielded three factors that reliably classified families externally verified as neglectful and nonneglectful control families.     

Integration of quality assessment and physician incentives

The ultimate challenge in dealing with any type of risk incentive system is to be able to integrate the quality of care and the cost of care into an equitable system and to monitor the system and detect either barriers to care or the withholding of appropriate services. We believe it is possible to do this and have based our incentive model upon this premise. At U.S. Healthcare, we have been successful in developing some measures of quality in the ambulatory setting and have tied the measurements to our payment mechanism.
