It is shown that there exists a truly marginal deformation of the direct sum of two Gk WZNW models at k = −2cV (G) (where cV (G) is the eigenvalue of the quadratic Casimir operator in the adjoint representation of the group G) which does not seem to fit the Chaudhuri-Schwartz criterion for truly marginal perturbations. In addition, a continuous family of WZNW models is constructed.

Two popular approaches for relating correlated measurements of a non-Gaussian response variable to a set of predictors are to fit a marginal model using generalized estimating equations and to fit a generalized linear mixed model by introducing latent random variables. The first approach is effective for parameter estimation, but leaves one without a formal model for the data with which to asse...

We adopted a person–organization (P–O) fit framework to examine applicant attraction to an organization in the context of Web-based recruitment. A total of 121 undergraduate business students participated in a two-stage study first by completing a paper-and-pencil survey and second, by visiting a fictitious recruitment Web site in which the researchers manipulated the fit feedback information p...

1 Anscombe’s term for such knowledge in Intention is “practical knowledge”. However, I have avoided that term as I wish to defend the idea that agents have a distinctive non-observational knowledge of their actions without being committed to her claims about the existence of a kind of knowledge with a reverse direction of fit from ordinary knowledge. 2 The idea originates in English speaking ph...

This study evaluated the accuracy of marginal and internal fit between the all-ceramic crowns manufactured by a conventional double-layer computer-aided design/computer-aided manufacturing (CAD/CAM) system and a single-layer system. Ten standardized crowns were fabricated from each of these two systems: conventional double-layer CAD/CAM system (Procera) and a single-layer system (Cerec 3D). The...

With improvement in material properties of ceramic restorative materials, these materials have been used as the definitive restoration material instead of the dental alloy, even in the posterior region. The incomplete fit of full crown restorations remains a critical problem for dentists, leading many researchers to study this problem. The distribution and magnitude of stress at any point can b...

The aim of this study was to investigate the effect of post-machining sintering on marginal and internal fit of CAD/CAM-fabricated zirconia frameworks. Single crown copings (A: abutment), three-unit bridge frameworks (APA, P: pontic), four-unit bridge frameworks (APPA), and five-unit bridge frameworks (A1P1A2P2A3) were fabricated with raw-stage zirconia blanks using a commercial CAD/CAM system ...
