An Investigation into the Effect that Technology had on the Strategies of J. Sainsbury plc, Tesco plc and Safeway plc: With a Particular Focus on the Period 1980 to 1990

This research is focused on three food multiple retailers, Sainsbury plc, Tesco plc, and Safeway plc. The research is designed to explore the relationship between technology and strategy in these organisations. The currently held view among the researchers and managers of these organisations is that technology has a limited impact on the processes that formulate strategy, and as such may be regarded as having an enabling role. This thesis proposes that while this view may have been correct in the past it is so no longer, and that technology is not following strategy but leading strategy in the food retailers examined. In order to confirm this thesis the history, technical development and technical structure of the three retailers was investigated. The results of this research was subsequently analysed and the following conclusions were made: a. Technology has a much greater inq)act on the strategy of multiple food retailers than has been previously thought. Technology defines the boundaries of operational activities, and, through controlling a substantial proportion of the information that managers use in the strategy making process, technology de facto if not de jure greatly influences the retailers strategies, and in some cases may actually lead them. b. The food multiples, in not appreciating the extent to which their fate is tied up with the information technology they are using, are foiling to educate and train the general management of the organisations technologically. c. Technological progress is widening the gap between the general management and technical management, and in the long run this will cause serious strategic problems unless this gap is closed through positive action

Investigation into the variations of moisture content of two buildings constructed with light earth walls

This paper briefly describes the background to light earth buildings and details a series of moisture measurements undertaken upon the clay and straw, (light earth) constructed walls of two UK based buildings. The methodology of measurement that was based upon previous studies undertaken on walls made from straw bales is described. A novel ‘in-wall’ wet heating system used in one of the two buildings allows the investigation of the effects of direct wall heating upon the distribution of moisture in the walls. The influence of exterior and interior temperature and humidity are described as are the variations in moisture migration introduced by the in-wall heating system. It was concluded that both buildings have exterior wall moisture content readings that indicate little risk of degradation due to interior wall moisture levels (although the Studio walls do exhibit higher and if suffered over long time periods, dangerous moisture readings for part of the measurement period)

Nanoscale Voltage Enhancement at Cathode Interfaces in Li-ion Batteries

Interfaces are ubiquitous in Li-ion battery electrodes, occurring across compositional gradients, regions of multiphase intergrowths, and between electrodes and solid electrolyte interphases or protective coatings. However, the impact of these interfaces on Li energetics remains largely unknown. In this work, we calculated Li intercalation-site energetics across cathode interfaces and demonstrated the physics governing these energetics on both sides of the interface. We studied the olivine/olivine-structured LixFePO4/LixMPO4 (x=0 and 1, M=Co, Ti, Mn) and layered/layered-structured LiNiO2/TiO2 interfaces to explore different material structures and transition metal elements. We found that across an interface from a high- to low-voltage material the Li voltage remains constant in the high-voltage material and decays approximately linearly in the low-voltage region, approaching the Li voltage of the low-voltage material. This effect ranges from 0.5-9nm depending on the interfacial dipole screening. This effect provides a mechanism for a high-voltage material at an interface to significantly enhance the Li intercalation voltage in a low-voltage material over nanometer scale. We showed that this voltage enhancement is governed by a combination of electron transfer (from low- to high-voltage regions), strain and interfacial dipole screening. We explored the implications of this voltage enhancement for a novel heterostructured-cathode design and redox pseudocapacitors

Participatory approach for integrated basin planning with focus on disaster risk reduction : the case of the Limpopo river

This paper defends the idea that a participatory approach is a suitable method for basin planning integrating both water and land aspects. Assertions made are based on scientific literature review and corroborated by field experience and research carried out in the Limpopo River basin, a transboundary river located in southern Africa which is affected by periodical floods. The paper explains how a basin strategic plan can be drafted and disaster risk reduction strategies derived by combining different types of activities using a bottom-up approach, despite an institutional context which operates through traditional top-down mechanisms. In particular, the "Living with Floods" experience in the lower Limpopo River, in Mozambique, is described as a concrete example of a disaster adaptation measure resulting from a participatory planning exercise. In conclusion, the adopted method and obtained results are discussed and recommendations are formulated for potential replication in similar contexts of the developing world
