E-learning Series No. 1: A guide for senior managers

This guide to e-learning for senior managers in universities outlines the context for e-learning and its use in higher education, both nationally and internationally. It identifies potential benefits and addresses the key issues in implementing e-learning successfully, including costs. It also highlights likely future developments

Accounting for Poverty Differences between the United States, Great Britain, and Germany

We propose a framework for comparing the relationship between poverty and personal characteristics across countries (or across years), and use it to compare levels and patterns of relative poverty in the USA, Great Britain and Germany during the 1990s. The higher aggregate poverty rates in the USA and in Britain relative to Germany were mostly accounted for by higher poverty rates conditional on characteristics, which were only partly offset by a more favourable distribution of poverty-relevant characteristics, in particular higher employment rates.Poverty, Singh-Maddala Distribution

Estimation of Generalized Entropy and Atkinson Inequality Indices from Complex Survey Data

Applying a method suggested by Woodruff (1971), we derive the sampling variances of Generalized Entropy and Atkinson inequality indices when estimated from complex survey data. It turns out that this method also greatly simplifies the calculations for the i.i.d. case when compared to previous derivations in the literature. Both cases are illustrated with examples from the German Socio-Economic Panel Study and the British Household Panel Survey.Inequality, Statistical Inference, Complex Surveys

Strong Λπ\Lambda \pi Phase Shifts for CP Violation in Weak Ξ→Λπ\Xi \rightarrow \Lambda \pi Decay

Strong interaction $\Lambda\pi$ phase shifts relevant for the weak nonleptonic decay $\Xi \rightarrow \Lambda \pi$ are calculated using baryon chiral perturbation theory. We find in leading order that the S-wave phase shift vanishes and the $J={1 \over 2}$ P-wave phase shift is $-1.7 ^{\rm o}$. The small phase shifts imply that CP violation in this decay will be difficult to observe. Our results follow from chiral $SU(2)_L\times SU(2)_R$ symmetry.Comment: 8 pages, uses phyzzx, 2 figures included as uuencoded file, CALT-68-1940 and CMU-HEP94-2

Strong and Electromagnetic Decays of the Baryon Decuplet

We discuss the strong and radiative decays of the decuplet of baryon resonances to the baryon octet in chiral perturbation theory. We comment on the implications for the polarisability of the nucleon.Comment: 16 pages + 5 figures (.ps files) appended to file. Uses tables.tex and harvmac.te

Electromagnetic Polarisability of the Nucleon in Chiral Perturbation Theory

We compute the polarisability of the nucleon to leading order in chiral perturbation theory. The contributions from kaons and baryon resonances as intermediate states are included in addition to the contribution from pions and nucleons that had been previously computed. The isoscalar operators are dominated by the infrared behaviour of pion loops giving rise to a $1/m_{\pi}$ coefficient. In contrast, the isovector operators are dominated by loops involving kaons, giving a $1/m_{k}$ coefficient, and further demonstrates that the strange quark is an important component of the nucleon. In addition, the inclusion of the decuplet of baryon resonances as intermediate states substantially modifies the result found from the octet baryons alone for the isoscalar polarisability.Comment: 11 pages (uses harvmac, figures available upon request) , UCSD/PTH 92-30, QUSTH-92-0

Achieving academic engagement? The landscape for educational technology support in two UK institutions

Drawing on results from a Universities and Colleges Information Systems Association (UCISA) 2008 survey of technology enhanced learning use in UK universities, this paper highlights support issues that impact on achieving academic engagement. It will crossreference factors that were identified by respondents to the survey as encouraging development or that act as barriers with how TEL is supported. These sector wide findings will then be reflected upon with reference to two UK universities that represent the traditional binary divide in type of university in the UK. Lack of time is identified as a primary barrier with staff development as the primary remedy.UCISA, JIS

S-wave phase shift in Lambda-pi scattering

We calculate the s-wave strong interaction $\Lambda$$\pi$ phase shift at the $\Xi$ mass taking into account contributions from the ${{\frac{1}{2}}}^{-}$ and ${{\frac{3}{2}}}^{-}$ $\Sigma$ resonances. We find the S-wave phase shift to be small, of the order of 0.3 degrees and bounded by 0.5 degrees.Comment: 4 page
