The Dynamics of Chart Success in the U.K. Pre-Recorded Popular Music Industry

In this paper we investigate the dynamics of chartsuccess in the U.K. pre-recorded popular music industryover the period 1980 to 1993 using the British albumchart listings. We find that the incidence of chartsuccess is substantially skewed to the right, whethermeasured by total weeks spent per artist, averageweeks spent per album, or the total number of albumslisted per artist. We subsequently investigatepossible determinants of the length of chart survivalof albums in order to determine what may be drivingthe observed skewness. Our results indicate that thetype of album, seasonal demand, and initial popularityplay an important role in ensuring continued chartlisting of an album.     

Lake Wobegon: Where All Teachers Are Competent (Or, Have We Come to Terms with the Problem of Incompetent Teachers?)

The major purpose of this study was to assess the presence of evaluation system components that assist principals in responding to incompetent teachers. According to Virginia principals, 5 per cent of the teachers in their schools were incompetent; however, only 2.65 per cent were documented formally as being incompetent. The typical principal with a staff of 100 teachers identifies 1.53 incompetent tenured teachers per year and remediates 0.68 teacher, encourages 0.37 teacher to resign or retire, reassigns 0.29 teacher, and recommends dismissal for 0.10 teacher. The four evaluation system components of remedial procedures, evaluation criteria, evaluator training, and organizational commitment were found to predict 69 per cent of the variance in the principals' effectiveness rating of their evaluation systems, but none of the evaluation system components were found to predict administrative responsiveness to incompetence. Such findings suggest that principals and school systems are avoiding a serious problem that undermines the education of millions of children, staff morale, and the publics perception of education.
