The emerging ethics of knowledge sharing: hacker ethics, participatory culture ethics and proselytization commons ethics
A key challenge that is emerging for organizations in nowadays is how to encourage knowledge sharing. Knowledge sharing is an activity through which knowledge is exchanged among people, a community or organization. Knowledge constitutes a valuable intangible asset for creating and sustaining competitive advantages. Knowledge sharing activities are generally supported by knowledge management systems. Nevertheless, technology comprises simply one of the several issues that influence organizational knowledge sharing, such as organizational culture, trust, and incentives. So, knowledge sharing entails a key challenge in the field of knowledge management because some individuals tend to resist sharing their knowledge with others (it may be an individual, a group, a community, or an organization). The aim of this chapter is to describe and discuss three emerging ethics of knowledge-sharing, namely: (1) hacker ethics, (2) participatory culture ethics, and (3) proselytization commons ethics. Future research directions are suggested and concluded the chapter

Structural characterization of interfaces in epitaxial Fe/MgO/Fe magnetic tunnel junctions by transmission electron microscopy
We present a detailed structural characterization of the interfaces in Fe/MgO/Fe layers grown by molecular-beam epitaxy using aberration-corrected transmission electron microscopy (TEM), scanning TEM, and electron energy-loss spectroscopy. When fabricated into magnetic tunnel junctions, these epitaxial devices exhibit large tunnel magnetoresistance ratios (e.g., 318% at 10 K), though still considerably lower than the values predicted theoretically. The reason for this discrepancy is being debated and has been attributed to the structure of, and defects at the interface, namely, the relative position of the atoms, interface oxidation, strain, and structural asymmetry of the interfaces. In this structural study, we observed that Fe is bound to O at the interfaces. The interfaces are semicoherent and mostly sharp with a minor degree of oxidation. A comparison of the two interfaces shows that the top MgO/Fe interface is rougher.1124sciescopu
