Are initial competitive advantages self-reinforcing, so that markets exhibit an endogenous tendency to be dominated by only a few firms? Although this question is of great economic importance, no systematic empirical study has yet addressed it. Therefore, we examine experimentally whether firms with an initial cost advantage are more likely to invest in cost reductions than firms with higher in...

Shallot plants in the horticultural plant require fertilizers and pesticides to grow develop. This research focuses on factors that influence behavior of shallot farmers use using approach predisposition, enabling, reinforcing factors. was conducted a quantitative descriptive Lembah Gumanti, Alahan Panjang Subdistrict, Solok Regency, West Sumatra. The selection Regency carried out purposively b...

BACKGROUND Colorectal cancer (CRC) screening has been found to be an effective tool for the control and prevention of this type of cancer, yet it is underutilized by African Americans. Consequently, African Americans with CRC are diagnosed at late stages and suffer disproportionately higher mortality rates for CRC. METHODS To understand factors that influence the decision to participate in CR...

Using the Precede-Proceed Model of Health Promotion (PPMHP) and an etiological systematic literature review, we examined the risk/protective factors of older driver safety in the United States. We described key features of this literature review and developed a structural model illustrating the prevalence of risk/protective factors in the health domain (63%) and in other PPMHP domains (environm...

Based on meso-damage mechanics and finite element analysis, the aim of this paper is to describe the feasibility of the Gurson-Tvergaard-Needleman (GTN) constitutive model in describing the tensile behavior of corroded reinforcing bars. The orthogonal test results showed that different fracture pattern and the related damage evolution process can be simulated by choosing different material para...

This review focusses on the fundamentals of NRR, factors influencing NRR kinetics and advent development transition metal-based catalysts such as borides, carbides nitrides due to their specific importance in reinforcing NRR.

With the explosive growth of information available on the World Wide Web, users must increasingly use automated tools to find, extract, filter, and evaluate desired information and resources. Companies are investing significant amounts of time and money on creating, developing, and enhancing individualized customer relationships, a process called customer relationship management, or CRM (Berry ...

In this study, the L*a*b* color system as a color system and light transmittance of the denture base resin reinforced with wire mesh and glass cloth were measured, and the color difference (deltaE*ab) was calculated using L*, a* and b* values which were measured both on a white calibration plate and on a null background. The thicknesses of test specimens, which were reinforced with wire mesh an...
