An empirical assessment of commercial web-based professor evaluation services

We examined the validity of data found on a popular web-based, user-created commercial professor evaluation service, RateMyProfessors.com (RMP), in business school settings. We compared publicly available RMP data for two business schools with official faculty evaluations unavailable to the public. We find that students rate professors significantly lower on RMP than on official university evaluations. However, we also find that the rankings of official university evaluations and RMP are significantly correlated (p < .001), with correlation values high enough to provide useful data to students.     

Faith at Work Scale (FWS): Justification,Development, and Validation of a Measure of Judaeo-Christian Religion in the Workplace

Workplace spirituality research has sidestepped religion by focusing on the function of belief rather than its substance. Although establishing a unified foundation for research, the functional approach cannot shed light on issues of workplace pluralism, individual or institutional faith-work integration, or the institutional roles of religion in economic activity. To remedy this, we revisit definitions of spirituality and argue for the place of a belief-based approach to workplace religion. Additionally, we describe the construction of a 15-item measure of workplace religion informed by Judaism and Christianity – the Faith at Work Scale (FWS). A stratified random sample (n = 234) of managers and professionals assisted in refining the FWS which exhibits a single factor structure (Eigenvalue = 8.88; variance accounted for = 59.22%) that is internally consistent (Cronbach’s α = 0.77) and demonstrates convergent validity with the Faith Maturity Scale (r = 0.81, p > 0.0001). The scale shows lower skew and kurtosis with Mainline and Catholic adherents than with Mormons and Evangelicals. Validation of the scale among Jewish and diverse Christian adherants would extend research in workplace religion.

Endogenous business cycle propagation and the persistence problem: The role of labor-market frictions

Contrasting sharply with a recent trend in DSGE modeling, we propose a business cycle model where frictions and shocks are chosen with parsimony. The model emphasizes a few labor-market frictions and shocks to monetary policy and technology. The model, estimated from U.S. quarterly postwar data, accounts well for important differences in the serial correlation of the growth rates of aggregate quantities, the size of aggregate fluctuations and key comovements, including the correlation between hours and labor productivity. Despite its simplicity, the model offers an answer to the persistence problem (Chari et al., 2000) that does not rely on multiple frictions and adjustment lags or ad hoc backward-looking components. We conclude modern DSGE models need not embed large batteries of frictions and shocks to account for the salient features of postwar business cycles.     

Does accounting quality change following a switch from U.S. GAAP to IFRS? Evidence from Germany

This study examines whether accounting quality changed following a switch from U.S. GAAP to IFRS. Using a sample of German high tech firms that transitioned to IFRS from U.S. GAAP in 2005, we find that accounting numbers under IFRS generally exhibit more earnings management, less timely loss recognition, and less value relevance compared to those under U.S. GAAP. In addition, after analyzing the accounting quality of firms that applied IFRS throughout the entire sample period, we find that, for the metrics suggesting a decline in accounting quality for both groups of firms, the change is significantly more pronounced for firms switching to IFRS from U.S. GAAP. Overall, our findings indicate that the application of U.S. GAAP generally resulted in higher accounting quality than application of IFRS, and a transition from U.S. GAAP to IFRS reduced accounting quality. Our findings provide the first evidence on the potential consequences of a switch from U.S. GAAP to IFRS.     

Virtual worlds

Games, role‐playing, and simulations as developmental tools have been used in education since the 1800s. An emerging form of collaborative game play is virtual worlds; however, the use of virtual worlds in leadership education has not been fully investigated. The purpose of this article is to (a) demonstrate how virtual worlds are a viable venue for leadership education, and (b) present a hierarchy of skills sets that can be developed in virtual world settings. In doing so, this article provides evidence that virtual worlds can be used as a new instructional delivery environment for leadership education as the appeal and intrinsic nature of virtual environments aligns well with the experiential framework of leadership education.
