A response to Kloep and Hendry
No full textThis article challenges some of the assumptions in Kloep M. and Hendry L. B. article “Over protection, Overprotection Overprotection. Young people in Modern Britain". In particular it draws attention to location, age, class ethnicity and gender as factors which will affect the extent to which young people's experience may or may not be over constrained by adult supervision. It also argues, drawing on key texts in the development of youth work, that skilled interventions and effective programmes may provide the framework and opportunities for the development of the skills and habits required to become "adult" which adolescent groups, isolated from adult support may lack
Reformulating empirical macro-econometric modelling
No full textThe policy implications of estimated macro-econometric systems depend on the formulations of their equations, the methodology of empirical model selection and evaluation, the techniques of policy analysis, and their forecast performance. Drawing on recent results in the theory of forecasting, we question the role of 'rational expectations'; criticize a common approach to testing economic theories; show that impulse-response methods of evaluating policy are seriously flawed; and question the mechanistic derivation of forecasts from econometric systems. In their place, we propose that expectations should be treated as instrumental to agents' decisions; discuss a powerful new approach to the empirical modelling of econometric relationships; offer viable alternatives to studying policy implications; and note modifications to forecasting devices that can enhance their robustness to unanticipated structural breaks
Ultrafast charge generation in a semiconducting polymer studied with THz emission spectroscopy
No full textEuan Hendry, Mattijs Koeberg, Juleon M. Schins, L. D. A. Siebbeles, and Mischa Bonn, Physical Review B, Vol. 70, article 033202 (2004). "Copyright © 2004 by the American Physical Society."We study the ultrafast charge generation in a semiconducting polymer (MEH-PPV) by measuring the radiated THz field after photoexciting the biased polymer with a femtosecond visible pulse. The subpicosecond temporal characteristics of the emitted wave reflects the ultrafast photoconductivity dynamics and sets an upper limit for charge generation of 200 fs following photoexcitation, and reveals the dispersive nature of charge transport in MEH-PPV. A comparison of the fields radiated from MEH-PPV and the well-characterized model semiconductor system (GaAs) allows for an accurate estimate of the quantum efficiency for charge generation in the polymer, found to be less than 1% . Both observations are consistent with ultrafast charge generation in semiconducting polymers through hot exciton dissociation
