Modelling the impact of university ICT strategies on learning
This research explores the potential of certain Future Studies techniques (Barbieri Masini, 1994) to provide insight into the question of how developing countries might best exploit Information and Communication Technology (ICT) for higher education.
First, three case studies were examined: the African Virtual University (AVU), the Arab Open University (AOU) and the Syrian Virtual University (SVU). From these accounts, key variables related to the research question were identified, the selection of variables validated by comparison with D–Antoni (2003). Globalisation is seen as a key change driver. Secondly, a model of 'ICT Strategy' was developed, elaborating the well-known concept of distance education 'generations', building on the work of Nipper (1989) and subsequent authors. A model of 'Student Learning' was also developed, drawing on Conole et al. (2004). These models were then coordinated to generate possible scenarios for how ICT strategy might influence student learning, making assumptions about 'typical' usage. There is no presumption of deriving ineluctable scenarios from unproblematic antecedent models; the aim rather was to explore the limitations of the best models currently available as generators of broad-brush scenarios, to try to understand the ways in which such models could be improved.
One interpretation is that if institutions, under pressure for globalisation, adopted 2nd generation technologies alone, the impact on Student Learning would be neglect of Social aspects. Meanwhile, although a mix of generations could in principle provide coverage of the whole Individual-Social dimension, if institutions adopted 3rd technologies alone, the impact on Student Learning would be neglect of Individual aspects. This provides support for the warning by Clegg et al (2003) that uncritical acceptance of pressures to adopt new ICT for education, under the rhetoric of 'student-centred learning', can in fact turn out to have negative consequences for students. Moreover, it should not be assumed that a move to using 5th and 6th generation technologies exclusively necessarily represents a progression. If the AVU chose this strategy without high bandwidth for online video conferencing, the analysis suggests that its students would miss out on Social aspects.
Nevertheless, it is also possible that a move straight to the fourth and subsequent generations could, in principle, provide coverage of the Individual-Social dimension, without the need for face-to-face tutorials or unreliable postal systems that feature in earlier generations.
Four scenarios are discerned, distinguished by the balance between presentation of information and direct experience on the one hand, and the level of student autonomy on the other. None of the case study universities is yet clearly positioned in a single scenario.
Examination of the strength of the analysis suggests that although some testable hypotheses have been generated in relation to diverse pedagogical scenarios, a richer selection of variables, more sophisticated models, and more detailed institutional data would be of value.

Annihilation Signals from Asymmetric Dark Matter
In the simplest models of asymmetric dark matter (ADM) annihilation signals
are not expected, since the DM is non-self-conjugate and the relic density of
anti-DM is negligible. We investigate a new class of models in which a
symmetric DM component, in the `low-mass' 1-10 GeV regime favoured for linking
the DM and baryon asymmetries, is repopulated through decays. We find that, in
models without significant velocity dependence of the annihilation cross
section, observational constraints generally force these decays to be
(cosmologically) slow. These late decays can give rise to gamma-ray signal
morphologies differing from usual annihilation profiles. A distinctive feature
of such models is that signals may be absent from dwarf spheroidal galaxies.Comment: 31 pages, 9 figures, v3; minor corrections, and reference added -

Building capacity in climate change policy analysis and negotiation: methods and technologies
Capacity building is often cited as the reason “we cannot just pour money into developing countries” and why so many development projects fail because their design does not address local conditions. It is therefore a key technical and political concept in international development.
Some of the poorest countries in the world are also some of the most vulnerable to the impacts of climate change. Their vulnerability is in part due to a lack of capacity to plan and anticipate the effects of climate change on crops, water resources, urban electricity demand etc. What capacities do these countries lack to deal with climate change? How will they cope? What steps can they take to reduce their vulnerability?
This innovative and high-profile research project was part of a larger project (called C3D) and conducted with non-governmental organisations in Senegal, South Africa and Sri Lanka. The research involved several participatory workshops and a questionnaire to all three research centres
Moving the Goalposts : A Comparative Case Study Analysis of The Belarusian Regime’s Political Use of the 2014 and 2021 Ice Hockey World Championships
Using a comparative case study analysis of the 2014 and 2021 IIHF World Championships, that are supplemented with a geopolitical code assessment, this thesis demonstrates that as of 2021, Belarus has entered a new pro-Russian stage of the cyclicality of Belarus-Russian relations following the pro-Western stage that had been observable since 2014. However, given the lack of a geopolitical narrative in Belarusian politics, this thesis analyses how the cyclicality of Belarus-Russian relations can be seen via the politicisation of sport. As such, this thesis addresses the research question of 'how the Belarusian regime, led by Aliaksandr Lukashenka, has used sport for political ends?' This includes how the regime have used mega-events to promote its political agenda of forming international partnerships, nation-building, and regime survival, all while preserving Lukashenka's style of adaptive authoritarianism.
This thesis concludes that how the political agenda is carried out varies depending on the stage of the cyclicality of Belarus-Russian relations in which the regime finds itself. Consequently, during a pro-Russian stage, the Belarusian regime will use sport to develop Eastern partnerships that will be dominant within Belarusian policy, promote a nation-building process that incorporates the Russkiy Mir concept, and ensures regime survival through suppression of the domestic opposition. However, during a pro-Western stage of relations, the Belarusian regime will use sport to construct dominating Western partnerships, a nation-building process centred on Rzeczpospolita, and assures regime survival through economic investments to strengthen public support
Homes for the soul
This thesis describes the creation of a body of paintings, Homes for the Soul, inspired by the paintings found in Retablos and home altars in Mexico. The paintings also incorporate wooden housing structures and found objects. The themes of the paintings express the artist\u27s Christian spirituality. The thesis presents historical background on Retablos and home altars of Mexico and the southwestern U.S., then describes the themes and creation of each piece of art in the artist\u27s thesis show
Photocatalytic production of organic compounds from CO and H2O in a simulated Martian atmosphere
[14C]CO2 and [14C]organic compounds are formed when a mixture of [14C]CO and water vapor diluted in [12C]CO2 or N2 is irradiated with ultraviolet light in the presence of soil or pulverized vycor substratum. The [14C]CO2 is recoverable from the gas phase, the [14C]organic products from the substratum. Three organic products have been tentatively identified as formaldehyde, acetaldehyde, and glycolic acid. The relative yields of [14C]CO2 and [14C]organics are wavelength- and surface-dependent. Conversion of CO to CO2 occurs primarily at wavelengths shorter than 2000 angstrom, apparently involves the photolysis of water, and is inhibited by increasing amounts of vycor substratum. Organic formation occurs over a broad spectral range below 3000 angstrom and increases with increasing amounts of substratum. It is suggested that organic synthesis results from adsorption of CO and H2O on surfaces, with excitation of one or both molecules occurring at wavelengths longer than those absorbed by the free gases. This process may occur on Mars and may have been important on the primitive earth
