TL;DR: In this article, the authors examined factors affecting employees' perceptions that their psychological contract has been breached by their organization, and factors affecting whether this perception will cause employees to experience feelings of contract violation.
Abstract: This study examines factors affecting employees' perceptions that their psychological contract has been breached by their organization, and factors affecting whether this perception will cause employees to experience feelings of contract violation. Data were obtained from 147 managers just prior to their beginning of new job (time 1) and 18 months later (time 2). It was found that perceived contract breach at time 2 was more likely when organizational performance and self-reported employee performance were low, the employee had not experienced a formal socialization process, the employee had little interaction with organizational agents prior to hire, the employee had a history of psychological contract breach with former employers, and the employee had many employment alternatives at the time of hire. Furthermore, perceived breach was associated with more intense feelings of violation when employees both attributed the breach to purposeful reneging by the employer and felt unfairly treated in the process. Theoretical and practical implications of these results are discussed. Copyright © 2000 John Wiley & Sons, Ltd.

TL;DR: In this paper, the authors explore the features of affine term structure models that are empirically important for explaining the joint distribution of yields on short and long-term interest rate swaps.
Abstract: In this paper, we explore the features of affine term structure models that are empirically important for explaining the joint distribution of yields on short and long-term interest rate swaps. We begin by showing that the family of N-factor affine models can be classified into N+1 non-nested sub-families of models. For each sub-family, we derive a maximal model with the property that every admissible member of this family is equivalent to or a nested special case of our maximal model. Second, using our classification scheme and maximal models, we show that many of the three-factor models in the literature impose potentially strong over-identifying restrictions on the joint distribution of short- and long-term rates. Third, we compute simulated method-of-moments estimates for several members of one of the four branches of three-factor models, and test the over-identifying restrictions implied by these models. We conclude that many of the extant affine models in the literature fail to describe important features of the distribution of long- and short- term rates. The source of the model misspecification is shown to be overly strong restrictions on the correlations among the state variables. Relaxing these restrictions leads to a model that passes several goodness-of-fit tests over our sample period.

08 Dec 2014TL;DR: In this paper, the authors exploit the redundancy present within the convolutional filters to derive approximations that significantly reduce the required computation, while keeping the accuracy within 1% of the original model.
Abstract: We present techniques for speeding up the test-time evaluation of large convolutional networks, designed for object recognition tasks. These models deliver impressive accuracy, but each image evaluation requires millions of floating point operations, making their deployment on smartphones and Internet-scale clusters problematic. The computation is dominated by the convolution operations in the lower layers of the model. We exploit the redundancy present within the convolutional filters to derive approximations that significantly reduce the required computation. Using large state-of-the-art models, we demonstrate speedups of convolutional layers on both CPU and GPU by a factor of 2 x, while keeping the accuracy within 1% of the original model.

TL;DR: A practical, new, face-centered-cubic dielectric structure which simultaneously solves two of the outstanding problems in photonic band structure and lends itself readily to microfabrication on the scale of optical wavelengths.
Abstract: We introduce a practical, new, face-centered-cubic dielectric structure which simultaneously solves two of the outstanding problems in photonic band structure. In this new ``photonic crystal'' the atoms are nonspherical, lifting the degeneracy at the W point of the Brillouin zone, and permitting a full photonic band gap rather than a pseudogap. Furthermore, this fully three-dimensional fcc structure lends itself readily to microfabrication on the scale of optical wavelengths. It is created by simply drilling three sets of holes 35.26\ifmmode^\circ\else\textdegree\fi{} off vertical into the top surface of a solid slab or wafer, as can be done, for example, by chemical-beam-assisted ion etching.

TL;DR: The results argue against a unidimensional understanding of parent involvement and support the view of the child as an active constructor of his or her school experience.
Abstract: This study had 2 goals. The first was to examine a multidimensional conceptualization of parent involvement in children's schooling, defined as the allocation of resources to the child's school endeavors. A second goal was to evaluate a model in which children's motivational resources (i.e., perceived competence, control understanding, and self-regulation) are mediators between parent involvement and children's school performance. 300 11-14-year-old children and their teachers participated. Factor analyses of a set of parent involvement measures supported the hypothesized 3 dimensions of parent involvement: behavior, intellectual/cognitive, and personal. Path analyses revealed indirect effects of mother behavior and intellectual/cognitive involvement on school performance through perceived competence and control understanding, and indirect effects of father behavior on school performance through perceived competence. The results argue against a unidimensional understanding of parent involvement and support the view of the child as an active constructor of his or her school experience.
