Knowledge mobilization: The new research imperative (Introduction)
Hovir can educational research have more impact~ How do we know the depth and scope of the impact it has~ \Vhat processes of knowledge exchange are most effective for increasing the uses of research results? How can researchproduced knmvlcdge be better 'mobilized' among users such as practising educators, policy-makers and the public communities? These sorts of questions, despite their many embedded definitional, philosophical and pragmatic problems, arc commanding urgent attention in educational discourses and research policies no\\r circulating in the UK and Europe, Canada and the USA and Australia and other parts of the world. This attention has been translated into powerful material exercises that shape \vhat is considered to be worthv·,lhile research and hmv research is funded, recognized and assessed. Granting agencies request knmvledge mobilization or knovdedge exchange plans and otTer special funds for these purposes. Researchers and universities arc explicidy directed, in research design and accountability, to emphasize knowledge exchange or mobilization - announced by one funding council as a core priority (SSHRC 2008, 2010)

Pulse-pumping of cascaded Raman fibre amplifiers
In this thesis, I investigate cascaded Raman fibre amplifiers (RFAs) pumped with shaped optical pulses delivered from a Yb doped fibre MOPA source. RFAs offer the potential to generate gain at any arbitrary wavelength with an appropriate pump source, limited only by the fibre’s transparency range. The use of a counter-propagating signal and pump creates a continuous gain, despite the instantaneous nature of stimulated Raman scattering (SRS). A high power Yb doped fibre source emitting around the 1050 to 1100 nm region offers a flexible pump source that can in principle be used to generate gain for any signal from ~1100 to 2000 nm in a silica-based fibre via cascaded SRS. This opens up opportunities for an ultrabroadband amplifier with unmatched spectral width. Furthermore, by using a pump source that is in a MOPA configuration there is a high degree of control over the output characteristics which offers the potential of near-instantaneous electronic control of ultra-broadband Raman gain spectra. In the simplest configuration, cascaded Raman wavelength shifting across a wide range of wavelengths using single-level pump pulses (i.e., approximate super-Gaussian pulses) is investigated. Using a silica-based highly nonlinear fibre (HNLF), cascaded Raman wavelength shifting up to seven Stokes orders is demonstrated and counter-propagating gain measurements are made across all seven Stokes orders. From a pump wavelength of 1064 nm, the peak gain of the 7th Stokes order was ~1575 nm which demonstrated the potential for gain covering more than 500 nm. I believe this is the first time such a measurement has been undertaken. Other fibre types were also studied for comparison. Furthermore, the noise performance and gain saturation properties of cascaded RFAs were investigated, as well. In a more advanced configuration, the Raman gain spectra produced from pumping the HNLF with step-shaped pump pulses are investigated. Such pulses consist of multiple levels with different, controllable, instantaneous powers. By adjusting the power of each step appropriately I show that different parts of the pulse transfer their energy to different Stokes orders, leading to a controllable gain spectrum covering multiple Stokes orders at the same time. I further study how the gain spectrum can be controlled by manipulating the individual duty cycle of each section of the step-shaped pump pulses as well as using multiple pump wavelengths in a time-division multiplexed pumping scheme. Single and dual wavelength pumping of various fibres with step-shaped pulses was experimentally demonstrated. Raman gain spectra spanning two and three Stokes orders and covering over 100 nm were realised. Computer simulations are also carried out for pumping with more than two pump wavelengths and for gain spectra targeting gain simultaneously up to seven Stokes orders and covering up to ~500 nm. This shows that the use of step-shaped pulses and multiple pump wavelengths allow for further increase and control of the useable bandwidth
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
Both spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
