In this study, we consider linear and especially cyclic codes over the non-chain ring Zp[v]/〈v − v〉 where p is a prime. This is a generalization of the case p = 3. Further, in this work the structure of constacyclic codes are studied as well. This study takes advantage mainly from a Gray map which preserves the distance between codes over this ring and p-ary codes and moreover this map enlighte...

We show that positive solutions of a semilinear elliptic problem in the Sobolev critical exponent with Newmann conditions, related to conformal deformation of metrics inR+, are asymptotically symmetric in a neighborhood of the origin. As a consequence, we prove for a related problem of conformal deformation of metrics in R+ that if a solution satisfies a Kazdan-Warner-type identity, then the co...

Interaction patterns are often used to present existing knowledge about user-interfaces in a generalised, but well-defined manner. Such patterns provide insight into the practises and assumptions of the design community. This paper presents a small number of patterns based on the concept of physical ontology. That is, the paper puts forward patterns in which computing concepts in a program are ...

Hartry Field’s views on the concept of truth have evolved substantially over the years. Two major phases may be distinguished in this evolution. First, in the 1970s, Field articulated inflationist theories of truth; more particularly, he proposed a distinctive correspondence account of truth. Second, in the 1990s, Field became an advocate of deflationist theories. We shall explain and criticall...

Scholars and practitioners are interested in board effectiveness, yet we know relatively little about directors’ engagement in the boardroom. We integrate identity theory and social identity theory research with literature on board monitoring and resource provision to model how directors’ multiple identities affect their behavior. We propose that directors’ strength of identification with multi...

We prove several new results concerning k-sets of point sets on the 2-sphere (equivalently, for signed point sets in the plane) and k-sets in 3-space. Specific results include spherical generalizations of (i) Lovász’ lemma (regarding the number of spherical k-edges intersecting a given great circle) and of (ii) the crossing identity for kedges due to Andrzejak et al. As a new ingredient compare...

where Par denotes the set of all partitions, |λ| denotes the size (sum of the parts) of λ, θ(λ) denotes the number of odd parts in the partition λ, and θ(λ′) denotes the number of odd parts in the conjugate of λ. In this paper, we generalize this result and provide a bijective proof of our generalization. This provides a simple combinatorial proof of Andrews’ result. Other combinatorial proofs ...

This study introduces a theory-based measure of employee performance (Role Based Performance Scale, RBPS) that is supported with results from a validation study using 10 data sets from six companies. In contrast to traditional, job-related measures of employee performance, we propose an alternative measure of performance based on role theory and identity theory. Because our results support the ...

By the 1960s most philosophers had adopted ‘physicalism’ ─ the view that physical causes fully account for mental activities. However, controversy persists about what count as ‘physical causes.’ ‘Reductive’ physicalists recognize only microphysical (elementary-particle-level) causality. Many (perhaps most) physicalists are ‘non-reductive’ ─ they hold that entities considered by other (‘special’...
