Public Knowledge of and Attitudes to Science: Alternative Measures That May End the “Science War”:

Abstract: Research on the public understanding of science has measured knowledge as acquaintance with scientific facts and methods and attitudes as evaluations of societal consequences of science and technology. The authors propose alternative concepts and measures: knowledge of the workings of scientific institutions and attitudes to the nature of science. The viability, reliability, and validity of the new measures are demonstrated on British and Bulgarian data. The instrument consists of twenty items and takes ten to fifteen minutes to apply. Differences in the representation of science are reported between the British and Bulgarian young elite, between the elite and the public in Bulgaria, between natural and social science students, and between beginners and advanced students in Britain. The use of these measures will extend the scope of science indicator measures used by the European Commission and the National Science Foundation, help the assessment of the socialization in university training, and may even c...

One-quasiparticle States in the Nuclear Energy Density Functional Theory

Abstract: We study one-quasiproton excitations in the rare-earth region in the framework of the nuclear Density Functional Theory in the Skyrme-Hartree-Fock-Bogoliubov variant. The blocking prescription is implemented exactly with the time-odd mean field fully taken into account. The equal filling approximation is compared with the exact blocking procedure. We show that both procedures are strictly equivalent when the time-odd channel is neglected, and discuss how nuclear alignment properties affect the time-odd fields. The impact of time-odd fields on calculated one-quasiproton bandhead energies is found to be rather small, of the order of 100-200 keV; hence, the equal filling approximation is sufficiently precise for most practical applications. The triaxial polarization of the core induced by the odd particle is studied. We also briefly discuss the occurrence of finite-size spin instabilities that are present in calculations for odd-mass nuclei when certain Skyrme functionals are employed.
