ABSTRACT

Our ability to interpret, generalize, and build theory across public service motivation (PSM) studies is limited by lack of knowledge regarding the equivalence of different PSM measures that researchers frequently use. While past research has given considerable attention to validating multidimensional measures of PSM, this study investigates the psychometric properties of the global measures that have been used to provide much of the empirical evidence on PSM. Building on the lessons of other research using global and multidimensional measures, we first discuss the strengths and weaknesses of existing global measures of PSM relative to those of the multidimensional measures. After highlighting the potential merit of global scales, we then provide empirical justification for global scales. Using five different data sets to compare commonly used global measures of PSM, our findings suggest that these different measures are not only highly correlated with each other but also display a similar pattern and strength of relationships with important correlates of PSM. These findings suggest that these measures do tap into the same conceptual space and help validate our continued reliance on empirical studies that have used different measures to build our understanding of PSM.  相似文献

This article examines the history of political science in relation to the history of the prison. It considers how theories of the state in political science have assumed that proper states should punish with prisons, and traces these ideas to the work of Francis Lieber, the first academic political scientist in the USA. Because his ideas about prison reform were central to his conceptualization of the discipline as a science of punishment, his theory of the state is an understudied part of the history of mass incarceration. Lieber argued that the state had a moral duty to punish its citizens with the prison, and an obligation to manage the risks of democracy through the prison's principles of scientific certainty, less eligibility, and disciplinary solitude. By examining the life and work of Francis Lieber, this article offers new ways of thinking about political science's past, and its status as part of the history of the American prison.  相似文献

Abstract

A simulation model that mirrors the actual practices of lenders in setting qualification requirements for mortgage loans is used to assess the impact of permanent buydowns and buyups on the maximum sale price that buyers can afford. Buydowns are reductions in the coupon rate traded off against higher discount points; buyups are the reverse. Although buydowns have little effect on afford ability, buyups can have significant effects. Their potential is largely unrealized, however, because of the call risk to lenders of loans carrying premiums. The authors propose a “discount recovery” provision, which would be similar to a prepayment penalty except that the payment upon prepayment would be tied to the amount of the discount foregone by the lender. This would protect lenders against call risk, giving them every reason to offer buyups as a way of expanding demand.  相似文献
