Factors influencing organizational knowledge transfer: implication for corporate performance

Abstract: Purpose – Whilst knowledge transfer is a major strategy for managing contemporary organizations the impact of the key factors influencing the rate of organization knowledge transfer is relatively unknown. As a contribution to this identified gap this paper aims to discuss the influence of particular organizational factors (IT systems, structured learning strategies, innovative organizational culture, and flexible structure and design) on knowledge transfer using a conceptual framework derived from the literature. The effect of both explicit and tacit knowledge transfer on innovative capabilities and organizational performance is to be examined.Design/methodology/approach – The survey study, conducted amongst 1,086 high‐tech companies, targeted chief executive officers), CFOs (chief financial officers), COOs (chief operation officers) or top managers/administrators as they provided more reliable environmental and organizational information.Findings – The study findings, based on a sample response rate of 1...

High-resolution in situ x-ray study of the hydrophobic gap at the water-octadecyl-trichlorosilane interface

Abstract: The knowledge of the microscopic structure of water at interfaces is essential for the understanding of interfacial phenomena in numerous natural and technological environments. To study deeply buried liquid water–solid interfaces, high-energy x-ray reflectivity measurements have been performed. Silicon wafers, functionalized by a self-assembled monolayer of octadecyl-trichlorosilane, provide strongly hydrophobic substrates. We show interfacial density profiles with angstrom resolution near the solid–liquid interface of water in contact with an octadecyl-trichlorosilane layer. The experimental data provide clear evidence for the existence of a hydrophobic gap on the molecular scale with an integrated density deficit ρd = 1.1 A g cm−3 at the solid–water interface. In addition, measurements on the influence of gases (Ar, Xe, Kr, N2, O2, CO, and CO2) and HCl, dissolved in the water, have been performed. No effect on the hydrophobic water gap was found.

A bibliography of temporal, spatial and spatio-temporal data mining research

Abstract: With the growth in the size of datasets, data mining has recently become an important research topic and is receiving substantial interest from both academia and industry. At the same time, a greater recognition of the value of temporal and spatial data has been evident and the first papers looking at the confluence of these two areas are starting to emerge. This short paper provides a few comments on this research and provides a bibliography of relevant research papers investigating temporal, spatial and spatio-temporal data mining.

Biofortified indica rice attains iron and zinc nutrition dietary targets in the field.

Abstract: More than two billion people are micronutrient deficient. Polished grains of popular rice varieties have concentration of approximately 2 μg g(-1) iron (Fe) and 16 μg g(-1) zinc (Zn). The HarvestPlus breeding programs for biofortified rice target 13 μg g(-1) Fe and 28 μg g(-1) Zn to reach approximately 30% of the estimated average requirement (EAR). Reports on engineering Fe content in rice have shown an increase up to 18 μg g(-1) in glasshouse settings; in contrast, under field conditions, 4 μg g(-1) was the highest reported concentration. Here, we report on selected transgenic events, field evaluated in two countries, showing 15 μg g(-1) Fe and 45.7 μg g(-1) Zn in polished grain. Rigorous selection was applied to 1,689 IR64 transgenic events for insert cleanliness and, trait and agronomic performances. Event NASFer-274 containing rice nicotianamine synthase (OsNAS2) and soybean ferritin (SferH-1) genes showed a single locus insertion without a yield penalty or altered grain quality. Endosperm Fe and Zn enrichment was visualized by X-ray fluorescence imaging. The Caco-2 cell assay indicated that Fe is bioavailable. No harmful heavy metals were detected in the grain. The trait remained stable in different genotype backgrounds.
