Studies in Government contracting are relatively new manifestation to academic research. Expanding theories to practitioner challenges may offer new concepts and insights to potential solutions to these challenges. Through a review of relevant literature, the researcher sought to 1) identify an operational definition of sustainability in government contracting and 2) bridge gaps in information ...

We consider string theory in a time dependent orbifold with a null singularity. The singularity separates a contracting universe from an expanding universe, thus constituting a big crunch followed by a big bang. We quantize the theory both in light-cone gauge and covariantly. We also compute some tree and one loop amplitudes which exhibit interesting behavior near the singularity. Our results a...

We establish two results under which the topology of a hyperbolic set constrains ambient dynamics. First if Λ is a compact, transitive, expanding hyperbolic attractor of codimension 1 for some diffeomorphism, then Λ is a union of transitive, expanding attractors (or contracting repellers) of codimension 1 for any diffeomorphism such that Λ is hyperbolic. Secondly, if Λ is a nonwandering, locall...

We investigated neuro-cognitive mechanisms involved with coordination of attention between current task performance and future action plans in prospective memory. We developed a novel task paradigm with continuous performance of a prospective memory task, where trial intervals of prospective memory targets were systematically manipulated in a periodic cycle of expanding and contracting target i...

This paper describes a study of spatially accelerating turbulent flow based on the direct numerical simulation with longitudinally moving walls to create relative acceleration between fluid and wall without inducing streamline curvature. The results show broad similarity those previous investigations spatial acceleration, albeit some differences. A new interpretation has been proposed consideri...
