πK\pi K Scattering in Three Flavour ChPT

We present the scattering lengths for the $\pi K$ processes in the three flavour Chiral Perturbation Theory (ChPT) framework at next-to-next-to-leading order (NNLO). The calculation has been performed analytically but we only include analytical results for the dependence on the low-energy constants (LECs) at NNLO due to the size of the expressions. These results, together with resonance estimates of the NNLO LECs are used to obtain constraints on the Zweig rule suppressed LECs at NLO, $L_4^r$ and $L_6^r$. Contrary to expectations from NLO order calculations we find them to be compatible with zero. We do a preliminary study of combining the results from $\pi\pi$ scattering, $\pi K$ scattering and the scalar form-factors and find only a marginal compatibility with all experimental/dispersive input data.Comment: 23 page

K→3πK\to3\pi Decays in Chiral Perturbation Theory

The CP conserving amplitudes for the decays $K\to3\pi$ are calculated in Chiral Perturbation Theory at the next-to-leading order. We present the expressions in a compact form with single parameter functions only. These expressions are then fitted to all available $K\to2\pi$ and $K\to3\pi$ data to obtain a fit of the parameters that occur. We compare with the work of Kambor, Missimer and Wyler.Comment: 27 pages, uses axodraw.sty, some misprints corrected. Short discussion on isospin breaking and final state interaction adde

ππ\pi\pi Scattering in Three Flavour ChPT

We present the scattering lengths for the $\pi\pi$ processes in the three flavour Chiral Perturbation Theory (ChPT) framework at next-to-next-to-leading order. We then combine this calculation with the determination of the parameters from $K_{e4}$ and the masses and decay constants and compare with the results of a dispersive analysis of $\pi\pi$ scattering. The comparison indicates a small but nonzero value for the $1/N_c$ suppressed NLO low energy constants $L_4^r$ and $L_6^r$.Comment: 30 page

International Coercion, Emulation and Policy Diffusion: Market-Oriented Infrastructure Reforms, 1977-1999

Why do some countries adopt market-oriented reforms such as deregulation, privatization and liberalization of competition in their infrastructure industries while others do not? Why did the pace of adoption accelerate in the 1990s? Building on neo-institutional theory in sociology, we argue that the domestic adoption of market-oriented reforms is strongly influenced by international pressures of coercion and emulation. We find robust support for these arguments with an event-history analysis of the determinants of reform in the telecommunications and electricity sectors of as many as 205 countries and territories between 1977 and 1999. Our results also suggest that the coercive effect of multilateral lending from the IMF, the World Bank or Regional Development Banks is increasing over time, a finding that is consistent with anecdotal evidence that multilateral organizations have broadened the scope of the “conditionality” terms specifying market-oriented reforms imposed on borrowing countries. We discuss the possibility that, by pressuring countries into policy reform, cross-national coercion and emulation may not produce ideal outcomes.http://deepblue.lib.umich.edu/bitstream/2027.42/40099/3/wp713.pd

Quelques problèmes d'emploi et de recrutement dans le secteur public de la recherche scientifique

SUMMARY As expenses devoted to research are jar from being constant, important changes in the number of research workers recruited by the government have occurred or are to be expected. Although available data are insufficient to forecast the number of research-workers and the progress of their careers, the author shows concern about the consequences that these changes are likely to have on the equilibrium of pyramids and on promotion in these careers.Un article sur les aspects statistiques de la gestion du personnel a été publié en 1971 dans Population. L'auteur s'y souciait des conséquences fâcheuses du laisser-faire et de problèmes techniques posés par le traitement de données déjà assez élaborées. Ce domaine a, jusqu'ici, été peu exploré. Dans cet article, M. Pierre Dhonte, assistant en sciences économiques à l'Université de Paris X, attire l'attention sur les difficultés provoquées par les à-coups du recrutement dans un corps particulier, celui de la recherche scientifique du secteur public.SUMARIO Debido a las variaciones de los gastos consagrados a la investigación cienúfica se verificaron y se pueden prever fluctuaciones importantes en el reclutamiento de los investigadores del sector público y otras se pueden prever. Aun cuando, por falta de datos adecuados, no se pueden hacer previ- siones acerca del numero de investigadores y de las posibilidades de promoción en esas carreras, el autor se preocupa de las consecuencias que dichos cambios no pueden dejar de tener en el equilibrio de los piramides y en el desarrollo de las carreras.Dhonte Pierre.
