Over the past several years, SRA International has served as a contractor to several federal agencies in various aspects of records management. Among other projects, in 2000–2001, SRA carried out a government-wide survey for the National Archives and Records Administration (NARA) which was published as Report on Current Recordkeeping Practices within the Federal Government. In 1997–1998 SRA con...

It is widely acknowledged that suppliers contribute positively to innovation in new product development. However, it remains rather unclear what suppliers actually contribute to innovation. Based on a literature review focusing on 80 articles, and a focus group meeting with strategic purchasing managers, a conceptual framework is developed categorizing different supplier inputs to innovation. T...

supply chain management is a set of guidelines for integration of chains, which aims to reduce costs and increase system services to customers. one of the most important issues for supply chain stockholders is procuring and purchasing requested items in a timely manner. thus, a variety of models have been proposed as purchasing strategy in supply chains. group purchasing is a system which leads...

An exciting subject in string theory is to consider some applications of the AdS/CFT correspondence to realistic systems like condensed matter systems. Since most of such systems are non-relativistic, an anisotropic scaling symmetry with the general value of dynamical critical exponent z plays an important role in constructing the gravity duals for non-relativistic field theories. Supersymmetri...

In this paper we support the idea that students and teachers will benefit from a computer-based system that assesses programming exercises and provide immediate and detailed feedback: students would be able to evolve in the right direction and teachers would follow and assess more fairly their students. This assessment should outperform the typical right/wrong evaluation returned by existing to...

In this paper, we aim at analyzing the characteristic of neuronal population responses to instantaneous or time-dependent inputs and the role of synapses in neural information processing. We have derived an evolution equation of the membrane potential density function with synaptic depression, and obtain the formulas for analytic computing the response of instantaneous re rate. Through a techni...

While young infants appear competent in some task contexts, older toddlers often show difficulty with the same concepts. They apparently fail to understand something that infants are competent of. Such discrepancy in performance is puzzling, but only if task performance is taken to reflect knowledge or competency. The current study makes a different assumption: Namely that task performance refl...
