The value of any pricing strategy is questionable if it is not congruent with the overall strategy of the firm. Pricing strategies, which do no reflect organizational goals, can detrimentally affect performance outcomes. Determining the benefit of specific strategies calls for models adapted to effectively measure the congruence between pricing strategies and venture strategies, and the influen...

Authenticity is a difficult and taxing notion in both the digital and the analogue world. It is a retrospective and by implication dynamic notion, a reaction to whether or not we are dealing with the genuine article, that an object is what it purports to be at a moment in time and its content can be validated using available technology. It is not an end in itself like a fresh herring, but a red...

We prove that the restriction of a probability measure invariant under a nonhyperbolic, ergodic and totally irreducible automorphism of a compact connected abelian group to the leaves of the central foliation is severely restricted. We also prove a topological analogue of this result: the intersection of every proper closed invariant subset with each central leaf is compact.

although the renowned story of oraynib is not properly grounded in reality, the writers, and especially the literati of various eras, have narrated it in their works. in this article, the tradition of this story is followed up in one era after another and it is disclosed that the legend of oraynib, just like other legends, has changed from one century to another and from one book to another, be...

The Library of Babel, described by Jorge Luis Borges, stores an enormous amount of information. The Library exists ab aeterno. Wikipedia, a free online encyclopaedia, becomes a modern analogue of such a Library. Information retrieval and ranking of Wikipedia articles become the challenge of modern society. While PageRank highlights very well known nodes with many ingoing links, CheiRank highlig...

Systolic complexes were introduced in Januszkiewicz–Świa̧tkowski [12] and, independently, in Haglund [10]. They are simply connected simplicial complexes satisfying a certain condition that we call simplicial nonpositive curvature (abbreviated SNPC). The condition is local and purely combinatorial. It neither implies nor is implied by nonpositive curvature for geodesic metrics on complexes, but ...

Abstract. One fragment (page 335) published with Ramanujan’s lost notebook contains two formulas, each involving a finite trigonometric sum and a doubly infinite series of Bessel functions. The identities are connected with the classical circle and divisor problems, respectively. This paper is devoted to the first identity. First, we obtain a generalization in the setting of Riesz sums. Second,...

Modern medical facilities place considerable reliance on electronic instrumentation for purposes of calibration and monitoring of therapeutic processes, many of which employ electrical and electronic apparatus that itself generates considerable levels of interference in the form of background electromagnetic radiation (EMR). Additionally diverse ambient conditions in the clinical environment su...

In interaction design for experience-oriented uses of technology, a central facet of aesthetics of interaction is rooted in the user’s experience of herself “performing her perception.” By drawing on performance (theater) theory, phenomenology and sociology and with references to recent HCI-work on the relation between the system and the performer/user and the spectator’s relation to this dynam...

We prove that there exists a function f ðcÞ such that the vertex set of every f ðcÞ-connected graph G can be partitioned into sets S and T such that each vertex in S has at least c neighbours in T and both G1⁄2S and G1⁄2T are c-connected. This implies that there exists a function gðc;HÞ such that every gðc;HÞ-connected graph contains a subdivision TH of H so that G VðTHÞ is c-connected. We also...
