Pseudoscalar-meson-octet-baryon coupling constants in two-flavor lattice QCD
(American Physical Society, 2009-04-01)
We evaluate the πΝΝ, π∑∑, πΛ∑, KΛN and K∑N coupling constants and the corresponding monopole masses in lattice QCD with two flavors of dynamical quarks. The parameters representing the SU(3)-flavor symmetry are computed ...
Effects of word-of-mouth versus traditional marketing: findings from an internet social networking site
(American Marketing Association, 2009-09)
The authors study the effect of word-of-mouth (WOM) marketing on member growth at an Internet social networking site and compare it with traditional marketing vehicles. Because social network sites record the electronic ...
Private-label use and store loyalty
(American Marketing Association, 2008-11)
The authors develop an econometric model of the relationship between a household’s private-label (PL) share and its behavioral store loyalty. The model includes major drivers of these two behaviors and controls for ...
Winners and losers in a major price war
(American Marketing Association, 2008-10)
Although retail price wars have received much business press and some research attention, it is unclear how they affect consumer purchase behavior. This article studies an unprecedented price war in Dutch grocery retailing ...
Optimal ambulance location with random delays and travel times
(Springer Science+Business Media, 2008-09)
We describe an ambulance location optimization model that minimizes the number of ambulances needed tonprovide a specified service level. The model measures service level as the fraction of calls reached within a given ...
Computational comparison of five maximal covering models for locating ambulances
(Wiley, 2009-01)
This article categorizes existing maximum coverage optimization models for locatingambulances based on whether the models incorporate uncertainty about (1) ambulanceavailability and (2) response times. Data from Edmonton, ...
Product innovations, advertising, and stock returns
(American Marketing Association, 2009-01)
Under increased scrutiny from top management and shareholders, marketing managers feel the need to measure and communicate the impact of their actions on shareholder returns. In particular, how do customer value creation ...
Ambulance location for maximum survival
(Wiley, 2008-02)
This article proposes new location models for emergency medical service stations. The models are generated by incorporating a survival function into existing covering models. A survival function is a monotonically decreasing ...
Spin content of Λ in QCD sum rules
(American Physical Society, 2009-06-01)
We calculate the isoscalar axial-vector coupling constants of the Λ hyperon using the method of QCD sum rules. A determination of these coupling constants reveals the individual contributions of the u, d, and the s quarks ...
