We compare two approaches for estimating state-level public opinion: disaggregation by state of national surveys and a simulation approach using multilevel modeling of individual opinion and poststratification by population share. We present the first systematic assessment of the predictive accuracy of each and give practical advice about when and how each(More)

D oes globalization's impact on the labor market affect how people vote? I address this question using a new dataset based on plant-level data that measures the impact of foreign competition on the U.S. workforce over an 8-year period. Analyzing change in the president's vote share, I find that voters were substantially more sensitive to the loss of local(More)

For decades, the Democrats have been viewed as the party of the poor, with the Republicans representing the rich. Recent presidential elections, however, have shown a reverse pattern, with Democrats performing well in the richer blue states in the northeast and coasts, and Republicans dominating in the red states in the middle of the country and the south.(More)
Business Process Management Systems are a rich source of events that document the execution of processes and activities within these systems. Business Process Analytics is the family of methods and tools that can be applied to these event streams in order to support decision-making in organizations. The analysis of process events can focus on the behavior(More)
By allowing voters to choose among candidates with competing policy orientations and by providing incentives for incumbents to shape policy in the direction the public desires, elections are thought to provide the foundation that links government policy to the preferences of the governed. In this article I examine the extent to which the preference/ policy(More)
The causes of bilateral asymmetries during able-bodied gait are unclear. These asymmetries may represent a form of functional asymmetry, which has been defined as a consistent task discrepancy between the two lower limbs. According to this theory, the non-dominant lower limb contributes more to support, while the dominant lower limb contributes more to(More)
The objective of this study was to determine if simple, shoulder movements use the dual control hypothesis strategy, previously demonstrated with elbow movements, and to see if this strategy also applies in the absence of visual feedback. Twenty subjects were seated with their right arm abducted to 90 degrees and externally rotated in the scapular plane.(More)
Markerless motion capture systems have developed in an effort to evaluate human movement in a natural setting. However, the accuracy and reliability of these systems remain understudied. Therefore, the goals of this study were to quantify the accuracy and repeatability of joint angles using a single camera markerless motion capture system and to compare the(More)
The aim was to examine the effects of training with real-time biomechanical biofeedback on technique and performance of rifle shooters. Top-level shooters were randomly assigned to biofeedback- (n = 5) and control- (n = 4) groups. Bi-weekly training of 20 shots air-rifle for 4 weeks, with pre- and post-tests of 20 shots air-rifle and smallbore, were(More)
