The design of any information management system (IMS) requires a clear strategy for its integration into the environment for which it is intended. Information management has been addressed in the objectives and plans of the Government of Uganda since independence in 1962, with varying degrees of success. The extensive changes that have taken place in the last few decades in Ugandan higher education have led to increased demands for managing student information. In turn a strategy for proper coordination of such data is necessary. The major aim of this study was to design such a strategy. The research therefore attempted to investigate the current state of the management and coordination of student information in Uganda. The needs and requirements of a student information management system (SIMS) and strategies for its integration in higher education programmes were established. The study carried out in the education sector was conducted using a qualitative research framework that provided a coherent set of propositions which explains the phenomenon of a SIMS. The researcher purposively selected the respondents (including key informants, administrators and student leaders) in this sector, who included people involved in the capture, storage, management and use of student information in various institutions in the given sector. Observably, the current state of the SIMS lacks a strategy to keep track of student information in Uganda. It was established that to ensure tracking of such data in the country, an identification system with standardised procedures in a coordinating structure is required together with a clear strategy for utilising the existing structures in the education sector. To design a strategy of this kind, a proposed framework for an integrated SIMS defined the principles, environment and contextual boundaries in terms of which the design is created. It defines the structure of a national student identification system and its coordination in the education sector in Uganda. Strategies for ensuring the sustainability of such a system and its implications for the socio-economic environment of higher education are considered. / Information Science / D. Lit. et Phil.

Do changes in how cross-equatorial energy transport is partitioned between the ocean and atmosphere impact the hemispheric climate response to forcing? To find out, we alter the cross-equatorial ocean heat transport in a state-of-the-art GCM and ascertain how changes in energy transport and its partitioning impact hemispheric climate and precipitation sensitivity following abrupt CO2-doubling. We further evaluate the applicability our results in CMIP6-class ESMs, where AMOC facilitates the northward cross-equatorial ocean heat transport. In our experiments, changes in ocean cross-equatorial energy transport trigger compensating changes in atmospheric energy transport through changes in the Hadley cells and a shift in the Intertropical Convergence Zone. However, the climate sensitivity in each hemisphere is linearly related to the ocean heat transport convergence, not atmospheric energy transport convergence, due to the impact of ocean heating on evaporation and atmospheric specific humidity. Similarly, we also find that ocean heat transport convergence controls the hemispheric precipitation sensitivity through the impact of ocean heating on surface evaporation. This relationship is also evident in CMIP6 models, where we find differences in hemispheric precipitation sensitivity to be related to the Atlantic Meridional Overturning Circulation (AMOC). Changes in the AMOC control hemispheric differences in upper ocean heat content, which then affect how the hydrologic cycle responds to CO2 forcing in each hemisphere. These results suggest that ocean dynamics impact the hemispheric climate response to CO2 forcing, particularly how much regional precipitation changes with warming. / Graduate

This Mater's thesis deals with the evaluation of pulse wave velocity using multi-channel whole-body impedance cardiography. Data were taken from the group of healthy volunteers whose impedance changes were measured during rest, respiratory maneuvers, tilt and stress exercise. The result of this measurement are values of peaks of pulse wave time shifts towards R-wave. The velocity values towards the thorax electrodes were recalculated on the basis of knowledge about the pulse wave time shifts and the distances from the heart to the scanned locations, which were measured using the arterial segment's lengths.
