Adjustment of provisional mortality series: the dynamic linear model with structured measurement errors

The authors "consider the problem of adjusting provisional time series using a bivariate structural model with correlated measurement errors. Maximum likelihood estimators and a minimum mean squared error adjustment procedure are derived for a provisional and final series containing common trend and seasonal components. The model also includes measurement errors common to both series and errors that are specific to the provisional series. [The authors] illustrate the technique by using provisional data to forecast ischemic heart disease mortality."     

The effects of regulatory tools on organizational populations

One of the main activities of regulation is the control of market development by influencing the number of firms in an industry, their entry into an industry, and their exit from an industry. Population ecology is used as a framework for explaining both the direct and indirect effects of regulatory activity on entry, exit, and market structure. This framework is then used to derive specific propositions about regulatory effects on entry, exit, and market structure in the health maintenance organization industry.     

From QA to TQM

In the decade from 1950 to 1960, two quality-related processes--medical audit and total quality management--were being developed, one directly in the health care field and the other in the manufacturing sector. These processes remained isolated from each other until the mid-1980s. Each would have a separate but major effect on the health care industry.     

From quality assurance to continuous quality improvement

To change from punitive and legalistic QA to positive and productive CQI, both attitudes and methods must change. This is a difficult challenge, but potential rewards for both the organization and its individual members suggest that the effort is worthwhile and deserves high priority. Members of the executive/management team will likely turn to physician executives for guidance on how to proceed.     

Common sense leadership

Common sense has to do with problem solving. In the complexities of everyday human life, we are faced time and again with the need to solve problems. In fact, every situation we face, at least at the first exposure, requires some form of problem solving. When we want food, we have to solve a series of problems from acquisition to preparation to serving and eating. When we deal with organizational needs, problem solving is the daily fare.
