Privatization of Municipal Wastewater Treatment

Privatization of wastewater treatment facilities was encouraged by changes in the law and in the attitude of government officials during the early 1980s The idea was for localities to benefit from the efficiency gains expected when operations were transferred from municipal administration to a profit-making organization. However, significant differences between the ideal and reality often existed, particularly when contracts all but eliminated the profit motive.     

Public choice in a local government setting

From its beginnings, public choice has always had a substantial component devoted to federalism and local government decision-making. The DeVoe Moore Center at Florida State University has made the study of local government within a public choice framework a core component of its mission. The Center held a conference February 17?C19, 2011, on public choice in a local government setting. This special issue of Public Choice contains the papers presented at that conference.     

Applying Rasch modeling to the validity of a control balance scale

Classical test theory approaches to measurement are based upon a number of fairly restrictive assumptions. The nature of these assumptions is such that scales designed to operationalize latent constructs are treated with little regard for the interaction between the human subject and the items that compose the measurement scale. A competing measurement approach, the Rasch model, has been advanced to improve upon the limitations of classical test theory. In this article, the Rasch model was applied to a scale designed to measure Tittle's control balance ratio. Analysis suggests that the original scale and response category options do not meet fundamental measurement. In particular, several items exhibited misfit (and were thus removed from the scale), response category options were reduced from eleven to four, and the scales that form the control balance ratio exhibited very little gender bias. An alternative control balance scale that retains the original items is presented, but this scale no longer summarizes the control balance ratio as one overall score. The implications of these results are addressed.
