Individual-Level Determinants of the Propensity to Shirk

Employee shirking, where workers give less than full effort on the job, has typically been investigated as a construct subject to group and organization-level influences. Neglected are individual differences that might explain why individuals in the same organization or work-group might shirk. The present study sought to address these limitations by investigating subjective well-being (a dispositional construct), job satisfaction, as well as other individual-level determinants of shirking behavior. Results identified several individual-level determinants of shirking. Implications of the results are discussed

Geophysical characterisation of the ocean–continent transition at magma-poor rifted margins

Geophysical characterisation of the ocean-continent transition (OCT) at magma-poor riftedmargins has focused primarily on the determination of P wave velocities using wide-angleseismic techniques. Such experiments have shown that the OCT is heterogeneous, but thattypically velocities increase gradually with depth from ~5.0 km/s at top basement to ~8.0km/s at ~5 km deeper, without a large and abrupt Moho transition. The velocity variationwith depth is similar to that of old fracture zone crust, and appears to differ from that ofoceanic crust formed at ultra-slow spreading rates, though sampling of the latter is limited.Typically, the OCT is characterised by weakly lineated, low amplitude magnetic anomalies;the interpretation of these anomalies remains controversial. The oceanward limit of the OCTremains poorly defined on many margins

Variance Analysis of Basis Weight Variation on the Pilot Machine

The purpose of this study was to determine the significance of the variations of the pilot machine of the Department of Paper Science and Engineering at Western Michigan University by variance analysis conducted on basis weight profiles obtained from the Industrial Nucleonics scanning basis weight gauge. The profiles obtained from the basis weight gauge were subjected to a computer program which computed the cross-direction, machine-direction, and random component variations and determined F-ratios. The F-ratio shows the significance of the component variation. Cross-direction variation was found to decrease with speed. Machine-direction variation showed no significant trend and the random variation decreased with speed. It was found that the F-ratio comparing the machine-direction component to the random component was significant at the one per cent confidence level and should be lessened if better operational efficiency for the pilot machine is desired

Simplified Neural Unsupervised Domain Adaptation

Unsupervised domain adaptation (UDA) is the task of modifying a statistical model trained on labeled data from a source domain to achieve better performance on data from a target domain, with access to only unlabeled data in the target domain. Existing state-of-the-art UDA approaches use neural networks to learn representations that can predict the values of subset of important features called "pivot features." In this work, we show that it is possible to improve on these methods by jointly training the representation learner with the task learner, and examine the importance of existing pivot selection methods.Comment: To be presented at NAACL 201

Systematic variation of the 12CO/13CO ratio as a function of star-formation rate surface density

We show that the12CO/13CO intensity ratio in nearby galaxies varies systematically as a function of the star formation rate surface density and gas surface density. The same effect is observed in different transitions, and in the 12CO/C18O ratio, while the 13CO/C18O ratio appears to remain constant as a function of the star formation rate surface density. We discuss the cause of these variations, considering both changes in the physical state of the gas, and chemical changes that lead to abundance variations. We used the observed correlations with C18O to suggest that abundance variations are unlikely to be causing the systematic trend observed with the star formation rate surface density, and thus that the mean gas temperature and/or velocity dispersion are systematically higher in higher star-formation rate surface density regions. We present the best fitting relations between the star formation rate surface density and the 12CO/13CO and 12CO/C18O ratios, and discuss how this effect can help us predict CO isotope emission from galaxies across the known universe.Comment: 7 pages, 4 figures, accepted to MNRA

The Gag Rule: From Compromise to Contradiction

This essay examines the gag rule of 1836, its motivations and effects. Enacted in 1836 to counter the growing vitriol of the slavery debates, it was later repealed in 1844, following sustained controversy. To begin, the essay analyzes the historical context which informed the rule’s enactment, going over the Second Great Awakening and its role in intensifying the abolitionist movement. It proceeds to examine both the proximate historical explanations for the gag rule, such as recent slave revolts, as well as the more abstract, theoretical arguments concerning how enforced silence can function within democratic legislation. Finally, the essay elucidates the effects of the gag rule and the factors contributing to its failure and ultimate repeal. It ends on a note regarding the proximate impacts of the gag rule in antebellum America, and the precedent it set for other “gag rules” in American society
