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

How should the judge or jury in a just criminal court treat a civil disobedient, someone who performs a conscientiously motivated communicative breach of the criminal law? Kimberley Brownlee contends that all else equal a court of law should neither convict nor punish such offenders. Though I agree with this conclusion, I contend that Brownlee mischaracterizes the nature of the criminal defense to which civil disobedients are entitled. Whereas Brownlee maintains that such actors ought to be excused for their criminal breach, I argue that they ought to enjoy a justification defense. Acts of civil disobedience are not (morally) wrongful violations of the law for which an actor ought not to be blamed; rather, they are violations of the law that are not (morally) wrong in virtue of their illegality. It is the absence of wrongdoing, and not merely the absence of fault, that renders the conviction and punishment of those who perform acts of civil disobedience inappropriate.  相似文献

Mars One is an ambitious, private plan to begin colonizing Mars using comprehensively screened volunteers who will make a one-way journey to the Red Planet. Its budget will be partially offset by broadcasting the adventure as a reality-TV program, beginning with the training of the astronauts, and ending with their settlement and, presumably, their deaths on the surface of Mars. In essence, the volunteers being sought for the Mars One project are human subjects in an experiment and ought to be treated as such under international provisions for the protection of human subjects or, at the very least, under a concern for the ethical conduct of a potentially groundbreaking project. In this article, I explore the question of whether the volunteers for Mars One are subject to standard protections for human subjects in scientific research, or to broader ethical concerns and protections for unique reasons, and whether they are being given the appropriate protections. I contend that, because of the individual and social impacts of the proposed project, and the nature and degree of risks, ethical concerns need to be addressed for this project to continue. Moreover, I recommend that an ethics committee be created to permanently oversee the project and provide guidance.  相似文献
