A large literature has described the effects of advancing age on cognitive laboratory tasks, but there have been few attempts to investigate its effects on everyday cognitive performance. The experiments reported are an attempt to explore the effects of age on the everyday memory task of comprehending and remembering events as conveyed by television and in everyday perception. The methodology used was cross-sectional with all subjects well-documented on a number of indices. These were assessed as predictors of performance on different cognitive tasks relating to the everyday memory task. Age per se was found to have a limited effect on performance, the best index of the cognitive effect of ageing being I.Q. test score. This index picked up most of the variance on the measurements taken. Experiments were designed to examine the elderlys' recall of television news broadcasts. These demonstrated that elderly people with low I.Q. test scores have difficulty recalling facts and details from such an information source. Subsequent experiments attempted to identify the processes which explain groups differences on this task.

The significant value of the ESPC is its alternative financing mechanism that authorizes Federal facilities regionalization without upfront investments. The paper focuses on Dyess Air Force Base's ESPC, as Dyess's benchmarking ESPC was selected for the Presidential Award recognition for Leadership in Federal Energy Management. The six major contracting processes within the three main management levels encompass many of the best-preactice characteristics. The interviews referenced herein with the service end-users, both the regional and local contracting officers, allow the reader to further understand how the Integrated Product Team's significant efforts resulted in a successful ESPC.

This thesis examines attempts to improve the efficiency of local authority bureaucracies during the 1980's. A number of significant policy initiatives such as the establishment of the Audit Commission, the pressure for local authorities to implement systems of performance measurement and the introduction of performance related pay schemes reflect this quest for improved value for money. The thesis reviews existing economic theories of bureaucracy which show how inefficiency arises in the public sector. Two major hypotheses within this literature are identified; bureaus are inefficient because it is in the interests of bureaucrats either to produce too much output (allocative inefficiency) and/or to produce output at above minimum cost (X-inefficiency). The policy prescriptions arising from this theoretical framework suggest that strategies to reduce inefficiency must aim to change bureaucratic behaviour. One strategy seeks to induce bureaucrats to produce efficiently, whilst the other seeks to provide sponsors with the necessary information on costs to enable them to force bureaucrats to produce efficiently. Performance related pay schemes, which aim to change bureaucratic behaviour, are concerned with eliminating labour X-inefficiency. Our research suggests that the diversity of current schemes reflects a lack of consensus over the definition of indicators of employee performance. The general result of the introduction of performance related pay has been increased salaries for senior officers. Our assessment of the work of the Audit Commission in the area of value for money audits and our empirical research on the impact of performance measurement in local authorities indicates that a wealth of information has been generated in the form of performance indicators (PIs). However, the use of this information as a control device is limited as these indicators are clearly biased towards measuring X-inefficiency as distinct from allocative efficiency.

While previous research describes a broad set of factors that discriminate between new product success and failure, both the study findings and the models developed have tended to be very general. This has made it difficult for those involved in NPD to apply the lessons presented - "they are unable to relate them directly to their own situation" (Craig & Hart, 1992: 38). However, the way companies undertake the process activities during the development and launch of a new product has regularly been identified as being critical to the outcome of the NPD project (Booz et al, 1982; Cooper, 1979,1980,1990; Crawford, 1984; Maidique & Zirger, 1984). This research fills a gap in the literature by explicitly focusing on the internal NPD process activities and project organisation within one industry, the Automotive Components Industry. The contribution of the research is to identify the critical success factors for the NPD process within Automotive Component firms, confirm whether different dimensions of success exist for this industry and identify whether the antecedents of successful NPD differ depending on the dimensions of success. A model was developed, which was then tested using a six page postal questionnaire sent out to UK automotive component suppliers. 76 completed questionnaires were collected from 66 firms. After a careful reliability and validity analysis of the measures used in the survey, a multiple regression analysis was undertaken to identify the critical success factors for each of the dimensions of success. The findings from this research validate many ideas presented in the NPD literature. However, what is evident from this research is that new product success dimensions can not be treated together, and that average models can be misleading. This may well have made it difficult for practitioners to relate the findings of previous studies to their specific development situations and could begin to explain why, despite all the research that has been undertaken in this area, failure rates are still so high.

This thesis is concerned with the design and evaluation of a small scale solarthermoelectric power generation system. The system is intended for electricity generation and thermal energy supply to small scale applications in developing countries of the sunny equatorial regions. Detailed design methodologies and evaluations of both the thermoelectric device and the solar energy collector, which are parts of the combined system, are presented. In addition to experimental evaluations, three theoretical models are presented which allow the design and evaluation of both the thermoelectric module and the solar energy collector. One of the models (a unified thermoelectric device model) concerns the geometrical optimization and performance prediction of a thermoelectric module in power generation mode. The model is unified in the sense that it accounts for the effect of all the parameters that contribute to the performance of the thermoelectric module, a number of which are ignored by the available design models. The unified model is used for a comparative evaluation of five thermoelectric modules. One of these is commercially available and the others are assumed to have optimum geometry but with different design parameters (thermal and electrical contact layer properties). The model has been validated using data from an experimental investigation undertaken to evaluate the commercial thermoelectric module in power generation mode. Results showed that though the commercially available thermoelectric cooling devices can be used for electricity generation, it is appropriate to have modules optimized specifically for power generation, and to improve the contact layers of thermoelement accordingly. Attempts have also been made to produce and evaluate thermoelectric materials using a simple melt-qucnching technique which produces materials with properties similar to those of the more expensive crystalline materials.
