Why Only Some Industries Unionize: Insights from Reciprocity Theory

This paper argues that the degree to which a given industry’s labor contracts are complete or incomplete is the major factor determining whether its workforce will be unionized. For instance, assembly line industries feature complete labor contracts because of the nature of the production technology: Either a worker keeps up with the line, or he does not. In such a situation, there is no chance...

Why Do Only Some Galaxy Clusters Have Cool Cores?

Flux-limited X-ray samples indicate that about half of rich galaxy clusters have cool cores. Why do only some clusters have cool cores while others do not? In this paper, cosmological N-body + Eulerian hydrodynamic simulations, including radiative cooling and heating, are used to address this question as we examine the formation and evolution of cool core (CC) and non-cool core (NCC) clusters. ...

Why property dualists must reject substance physicalism

I argue that property dualists cannot hold that minds are physical substances. The focus of my discussion is a property dualism that takes qualia to be sui generis features of reality.

Why Do Only Some Events Cause Learning During Human Tutoring?

Developers of intelligent tutoring systems would like to know what human tutors do and which activities are responsible for their success in tutoring. We address these questions by comparing episodes where tutoring does and does not cause learning. Approximately 125 hr of tutorial dialog between expert human tutors and physics students are analyzed to see what features of the dialog are associa...
