Service innovations are central concerns in fast changing environment. Due to the fitness in customer demands and advances in information technologies (IT) in service management, an expanded conceptualization of e-service innovation is required. Specially, innovation practices have become increasingly more challenging, driving managers to employ a different open innovation model to maintain com...

Enzyme function is often dependent on fluctuations between inactive and active structural ensembles. Adenylate kinase isolated from Escherichia coli (AK(e)) is a small phosphotransfer enzyme in which interconversion between inactive (open) and active (closed) conformations is rate limiting for catalysis. AK(e) has a modular three-dimensional architecture with two flexible substrate-binding doma...

The Internet changes the way business is conducted. It provides an affordable and easy way to link companies with their incorporating trading and distribution partners as well as customers. However, the Internet’s potential is jeopardized by the rising digital anarchy: closed markets that cannot use each other’s services; incompatible applications and frameworks that cannot interoperate or buil...

This paper explores open source as a metaphor for e-learning. It builds the case that e-learning and open source movement are rooted in the constructivist movement and the constructivist movement is itself rooted in the pragmatism and instrumentalism that pervades John Dewey’s theories of understanding as applied to learning. As a result, it is recommended that the use of open source as metapho...

The Lipschitz and C harmonic capacities κ and κc in R n can be considered as high-dimensional versions of the so-called analytic and continuous analytic capacities γ and α (respectively). In this paper we provide a dual characterization of κc in the spirit of the classical one for the capacity α by means of the Garabedian function. Using this new characterization, we show that κ(E) = κ(∂oE) for...

Today there exists a variety of efforts to bring public administration closer to its customers (citizens, entrepreneurs, etc.). This paper investigates the concept of open innovation, i.e. the integration of the customer into the product creation process of a company, w.r.t. its applicability in the area of e-government. The concept of open innovation is well known within the context of mass cu...

This research paper aims to present an integrated evaluation model in e-learning systems for students. The paper describes the phases of development and analysis of the application of a web-based open student evaluation model in an e-Learning System. The proposed model has been tested and evaluated in terms of its effectiveness on student communication, collaboration, and progress. The evaluati...
