This paper provides an explicit treatment of the link between competitive advantage and random variability in value creation. Using a series of value-based formal models, the paper addresses (1) why random variability in a firm’s value creation strategy should be considered positive rather than negative; (2) how horizontal differentiation, the level of competition, and the cost of variability d...

This study of the digital divide within Japan utilizes data from Japan’s 47 prefectures for spatial analysis of distributions of technology utilization variables. It analyzes the spatial outliers and clusters of prefectures for the country. The paper constructs a conceptual model based on 10 dependent factors and 17 independent ones. The relationship of the independent to dependent factors is m...

The spatial distribution pattern and population structure of trees are shaped by multiple processes, such as species characteristics, environmental factors, intraspecific interspecific interactions. Studying the patterns species, associations, their relationships with factors is conducive to uncovering mechanisms biodiversity maintenance exploring underlying ecological processes community stabi...

We studied the complete randomness of the angular distribution of gammaray bursts (GRBs) detected by BATSE. Since GRBs seem to be a mixture of objects of different physical nature we divided the BATSE sample into 5 subsamples (short1, short2, intermediate, long1, long2) based on their durations and peak fluxes and studied the angular distributions separately. We used three methods, Voronoi tess...

We consider the effect of a random longitudinal field on the Ising model in a transverse magnetic field. For spatial dimension d > 2, there is at low strength of randomness and transverse field, a phase with true long range order which is destroyed at higher values of the randomness or transverse field. The properties of the quantum phase transition at zero temperature are controlled by a fixed...

Nonuniformity is a central concept in computational complexity with powerful connections to circuit and randomness. Nonuniform reductions have been used study the isomorphism conjecture for NP completeness larger classes. We power of nonuniform NP-completeness, obtaining both separations upper bounds vs uniform complessness NP. Under various hypotheses, we obtain following separations: also con...

Abstract: Some people automatically and involuntarily ”see” mental images of numbers in spatial arrays when they think of numbers. This phenomenon, called number forms, shares three key characteristics with the other types of synaesthesiae, within-individual consistency, between-individual variety, and mixture of regularity and randomness. An experiment was conducted to investigate whether ment...

We present a model that allows for the derivation of the experimentally accessible observables: spatial steps, mean velocity, stall force, useful power, efficiency and randomness, etc. as a function of the [adenosine triphosphate] concentration and an external load F. The model presents a minimum of adjustable parameters and the theoretical predictions compare well with the available experiment...
