Redundant screwjack

Device uses differential gears to drive either one of two nut-screw assemblies. In event that one assembly jams, second assembly is driven at twice its normal rate with no loss in overall performance

When Stock Options Fail to Motivate: Attribution and Context Effects on Stock Price Expectancy

This study draws on attribution theory and literature from compensation and strategy to investigate executives’ perceptions about their influence over the firm’s stock price. We define stock price expectancy as the extent to which executives feel that they can influence the firm’s stock price. Results from of a survey of 435 U.S. executives suggest that stock price expectancy is related to both attributional and contextual antecedents. Based on these findings we discuss implications for the extension of expectancy theory and the design and administration of incentive systems

“You’re Nobody ‘til Somebody Loves You”: The Use of Job Search for Bargaining Leverage

The purpose of this research is to investigate a previously overlooked yet important objective for an employee engaging in job search – seeking alternative employment to obtain leverage against the current employer. We focus specifically on how employees conduct job search to obtain leverage, and then turn to the question of what motivates employees to adopt this objective. Using a sample of high-level managers, our results indicate the leverage-seeking job search predicts both preparatory and active search beyond the more traditional reason for engaging in job search (i.e., to change jobs). However, as expected, leverage-seeking search was a weaker predictor of the job search processes compared to searching to leave and was not significantly related to job satisfaction. Hierarchical level, perceived alternatives, financial independence, and the meaning attached to money significantly predicted leverage-seeking search, while compensation level, equity, and career plateau showed little effect. Implications for practice and future research on job search and employee retention more generally are discussed

The Relationship Between Job Search Objectives and Job Search Behavior

This research expands the notion of “job search” beyond traditional models of searching for an alternative yet similar job, arguing that motivations for search are varied. Specifically, we investigate whether search objectives associate with use of different search processes. A study of high-level managers found mixed support for the hypotheses

Correlated emission and spin-down variability in radio pulsars

The recent revelation that there are correlated period derivative and pulse shape changes in pulsars has dramatically changed our understanding of timing noise as well as the relationship between the radio emission and the properties of the magnetosphere as a whole. Using Gaussian processes we are able to model timing and emission variability using a regression technique that imposes no functional form on the data. We revisit the pulsars first studied by Lyne et al. (2010). We not only confirm the emission and rotational transitions revealed therein, but reveal further transitions and periodicities in 8 years of extended monitoring. We also show that in many of these objects the pulse profile transitions between two well-defined shapes, coincident with changes to the period derivative. With a view to the SKA and other telescopes capable of higher cadence we also study the detection limitations of period derivative changes.Comment: 4 pages, 2 Figures, Proceedings of IAU Symposium 337 "Pulsar Astrophysics - The Next 50 Years" held at Jodrell Bank Observatory, UK Sept. 4-8 201
