We perform a nonperturbative calculation of the S0 NN scattering amplitude, using an effective field theory (EFT) expansion. We use dimensional regularization throughout, and the MS renormalization scheme; our final result depends only on physical observables. We show that the EFT expansion of the quantity |p| cot δ(p) converges at momenta much greater than the scale Λ that characterizes the de...

Electronic commerce has been introduced to the business community at a very fast pace. The Internet’s ease of use in particular resulted to a rapid growth of electronic transactions in a spontaneous manner. Governments worldwide are anxious to control this new means and have to balance between international cooperation and care for specific national needs. In this paper we examine the role of g...

On June 18, 2003, the Payment Cards Center of the Federal Reserve Bank of Philadelphia and the Electronic Commerce Payments Council (eCPC) of the Electronic Funds Transfer Association co-hosted a workshop forum to explore areas of mutual interest related to the proliferation of e-commerce payments. This was the second event jointly sponsored by the groups. The first forum, “The Future of e-Comm...

Advances in electronic transaction have uniquely transform business transaction strategies through convenient and low cost medium. Though electronic commerce (e-commerce) has found its way into many organization globally, numerous studies reported that its adoption have been constrained by inefficient operation and lack of infrastructural facilities. These barriers have been recognized to have ...

This article examines how sense-making activities in the entrepreneurial, growth-oriented small firm influence performance outcomes. It employs various constructs drawn from the literature and explores how each one affects others, leading to a dynamic model of sense making in the firm. Important constructs include the collective schema the set of moreorless shared beliefs that inform and guide ...

The renormalization in nonperturbative regimes are investigated in a compact and general parametrization of the T -matrix for nucleon-nucleon scattering. The underlying theory perspective and the ’fixing’ of the prescriptions for the T -matrix from physical boundary conditions are stressed.

When we cannot concentrate on reading a book, we have problems with voluntary attention. When we stand up and stumble on a chair leg, we have a problem with involuntary attention. A bimanual Stroop task (ST) and the Ericson’s flanker task (EFT) were used for the analysis of voluntary and involuntary attention, respectively. Electrophysiological markers of attention were applied in adult ADHD pa...

The risks from participating in P2P transactions are relatively high. To mitigate such risk a reputation scheme could be applied. Reputation schemes have emerged as a promising means for enabling electronic transactions with strangers. In order to gain optimal results from the reputation scheme, the privacy of feedback provider should be correctly addressed. The feedback provider should be allo...
