Time-frequency characterization of femtosecond extreme ultraviolet pulses
A measurement of chirp and pulse duration of fifth harmonic of a frequency-doubled Ti:sapphire laser was presented. The photoelectron signal due to cross correlation of harmonics generated by 400 nm blue light and an 800 nm infrared probe pulse, was measured using energy resolved cross-correlation method. Results demonstrated that the technique could be used to characterize the time-frequency behavior of much higher-order harmonics
Interpreting planners' talk about change: An exploratory study.
Talk by planners about major changes (‘reform’) in a particular planning regime is the focus of this article. Change in planning in the United Kingdom has been a recurrent theme in planning practice and research. However, there is little looking at practitioners both in the public and the private sectors in relation to change. Also, theory development has been limited and the interpretive link between institutional change, organisational change and planners’ situated agency could be strengthened. This article aims to add new dimensions to the current debate by looking at planners in both the public and the private sectors in Wales; by adopting a more open-ended approach requiring planners to generate ideas and display a perspective on planning; and by linking theories of institutional and organisational change with the model of actors’ agency developed by Bevir and Rhodes to form an interpretive frame. With reflections stemming from an exploratory case in Wales, the article seeks also to contribute to debates on planning in the United Kingdom and beyond, reaching to new-institutionalist theory and interpretive ontologie
