Selecting and implementing design tools and practices for use in the development of new products is more of a corporate bet than a guaranteed investment . Driven by the external forces of market opportunity, technological progress, and competitive pressure, manufacturing companies typically review available design tools and practices, hoping to choose those that will help produce a sustained co...

The dominant narrative of the Internet has been one of unconstrained growth, abundance, and plenitude. It is in this context that new forms of organizing, such as online groups, have emerged. Yet the same factors that underlie the utopian narrative of Internet life also give rise to numerous online groups, many of which fail to attract participants or to provide much significant value. This sug...

This paper summarizes the main areas of research within TA Weinberg, namely an investigation into code review ability and personality; an investigation into code comprehension and personality; and an investigation into the results from an online programming competition and personality. With regard to code review, it was discovered that there is a relationship between code review ability and per...

This paper presents a case study where competitive e-learning strategies are used in the teaching of an undergraduate Database course in order to develop, in university students, the capacity to actively research and to lead their own learning process. The experience has been carried out in the spring semester (February-June 2007) and is based on the use of the QUEST system. This tool for activ...

To improve the growth rate and crystal quality of AlN, the competitive growth mechanisms of AlN under different parameters were studied. The mass transport limited mechanism was competed with the gas-phase parasitic reaction and became dominated at low reactor pressure. The mechanism of strain relaxation at the AlN/Si interface was studied by transmission electron microscopy (TEM). Improved dep...

Managerial attitudes play an important role in facilitating the championship of innovation adoption. However, there are few empirical studies which show the mediating role of managerial attitudes as a link between innovation determinants and adoption. Based on innovation theory (Rogers, 1983), we posit a conceptual model to show how managers evaluate internal (relative advantage and compatibili...

We study a model ecosystem by means of dynamical techniques from disordered systems theory. The model describes a set of species subject to competitive interactions through a background of resources, which they feed upon. Additionally direct competitive or co-operative interaction between species may occur through a random coupling matrix. We compute the order parameters of the system in a fixe...

CO2 flooding of coalbed methane (CO2-ECBM) not only stores CO2 underground and reduces greenhouse gas emissions but also enhances the gas production ratio. This coupled process involves multi-phase fluid flow and coal-rock deformation, as well as processes such as competitive gas adsorption and diffusion from the coal matrix into fractures. A dual-porosity medium that consists of a matrix and f...
