Mass hierarchy, 2-3 mixing and CP-phase with Huge Atmospheric Neutrino Detectors

Abstract: We explore the physics potential of multi-megaton scale ice or water Cherenkov detectors with low ($\sim 1$ GeV) threshold. Using some proposed characteristics of the PINGU detector setup we compute the distributions of events versus neutrino energy $E_ u$ and zenith angle $\theta_z$, and study their dependence on yet unknown neutrino parameters. The $(E_ u - \theta_z)$ regions are identified where the distributions have the highest sensitivity to the neutrino mass hierarchy, to the deviation of the 2-3 mixing from the maximal one and to the CP-phase. We evaluate significance of the measurements of the neutrino parameters and explore dependence of this significance on the accuracy of reconstruction of the neutrino energy and direction. The effect of degeneracy of the parameters on the sensitivities is also discussed. We estimate the characteristics of future detectors (energy and angle resolution, volume, etc.) required for establishing the neutrino mass hierarchy with high confidence level. We find that the hierarchy can be identified at $3\sigma$ -- $10\sigma$ level (depending on the reconstruction accuracies) after 5 years of PINGU operation.

Intellectual capital management as part of knowledge management initiatives at institutions of higher learning

Abstract: Aspects such as human capital, structural capital and customer capital are important variables of the whole intellectual capital management programme, which forms part of the knowledge management initiatives of institutes of higher learning. The skills and expertise of university staff as part of its human capital are discussed. Structural capital will encompass aspects such as the role of innovation and intellectual property rights. Customer capital of the university and the knowledge of stakeholders in the field of tertiary education are becoming more important. The results of a study done at a South African university are used to indicate which of these aspects needs to be measured and a new framework for measurement and management of IC is discussed.

COVID-19 and African tourism research agendas

Abstract: COVID-19 has triggered a burst of international scholarship concerning the reshaping of tourism and the resetting of tourism research agendas. The aim of this paper is to tease out some implication...
