Pressure-volume X-ray diffraction data were collected at eight pressures to 17.2 GPa for synthetic single-crystal forsterite, Mg2Si04. Birch-Murnaghan equation-of-state parameters were determined to be Ko = 125(2) GPa and K~ = 4.0(4). To ensure hydrostatic conditions, we monitored the diffraction-peak shapes while the sample was in different pressure media: 4:1 methanol-ethanol, He, and Ar. The...

This paper develops a model to analyze economic performance under different political regimes. An “oligarchic” society, where political power is in the hands of major producers, protects their property rights but also tends to erect significant entry barriers against new entrepreneurs. Democracy, where political power is more widely diffused, imposes redistributive taxes on producers, but tends...

Are There Civic Returns to Education? " …since the achievement of American Independence, the universal and ever-repeated argument in favor of Free Schools has been, that the general intelligence which they are capable of diffusing, and which can be imparted by no other human instrumentality, is indispensable to a republican form of government. " Horace Mann (1846) INTRODUCTION Economists typica...

— What were the structural determinants of the recent Arab Awakening protests that engulfed the Arab world? We examine the economic and political grievances along with political opportunities. Time-series analysis of nonviolent and violent protests in 18 Arab-majority countries shows that “bread,” “justice,” and political opportunities mattered. State terror and political openness had the stron...

In the literature, innovation is the outcome of spatial interactions between the innovative structure of a district and its knowledge structure: innovations tend to concentrate in the locations where they find knowledge that is necessary for the development of innovating activities. Thus, proximity increases the chance of developing new ideas (Feldman, 1999). Starting from this theoretical hypo...

Public sector organisations are increasingly becoming aware of the need to harness the innovative capacity of their employees. In the UK many public sector research institutes have put in place processes to increase the speed at which new technological innovations are exploited and commercialised. These types of initiatives have also been implemented into public sector service organisations. Fo...

The cross-boundary knowledge transactions between foreign companies and local companies in developing countries can be a useful source of knowledge for both foreign companies and local companies. With the increased investments in buildings and infrastructure by developing countries, the cross-boundary knowledge transactions between foreign companies and local companies in developing countries i...

Contact centres represents critical component in the value chain through their differentiating role in service delivery. The vitality is assessed in terms of performance and global service quality that is brought into sharp focus if the centre is outsourced because of the impact of the strategic behaviour of the principal and its relation with its agents. The association of employees with the b...

materials and methods the segmentation process is evaluated using four different clustering methods with different number of clusters where some dti scalar indices for 10 human brains are processed. results the aim was to produce results with less segmentation error and a lower computational cost while attempting to minimizing boundary overlapping and minimizing the effect of artifacts due to m...

Systems development in organizations is well recognized as a knowledge-intensive eft'ort. Since the relevant application domain knowledge is thinly spread across an organization, the acquisition, sharing, and integration of knowledge are significant activities during the development process. Advocates of computer-aided software engineering tools (CASE) claim that these tools offer a potentially...
