Short-Term Load Forecasting: The Similar Shape Functional Time Series Predictor

We introduce a novel functional time series methodology for short-term load forecasting. The prediction is performed by means of a weighted average of past daily load segments, the shape of which is similar to the expected shape of the load segment to be predicted. The past load segments are identified from the available history of the observed load segments by means of their closeness to a so-called reference load segment, the later being selected in a manner that captures the expected qualitative and quantitative characteristics of the load segment to be predicted. Weak consistency of the suggested functional similar shape predictor is established. As an illustration, we apply the suggested functional time series forecasting methodology to historical daily load data in Cyprus and compare its performance to that of a recently proposed alternative functional time series methodology for short-term load forecasting.Comment: 22 pages, 6 Figures, 1 Tabl

"This brings back a lot of memories": a case study in the analysis of digital video production by young learners

This paper discusses a three and a half minute video written, shot and edited by two eleven year old children in London in the summer of 2003. Key questions which were used to structure the discussion included the following: When the children work in a school setting in a medium which is culturally closer to their experiences of life outside than is usual within the curriculum, how do they choose to represent themselves? Which aspects of their lives and/or media experiences do they employ and in which modes? How are these choices related to the meanings they wish to convey? Which aspects of the form and function of digital video authoring allow the children to move the locus of control of activities closer to themselves? What does a discussion of these issues tell us about possible future directions in researching young learners’ digital video production? Frameworks for analysing the piece were drawn from emerging theories of multimodal literacy, from studies of ICT in Education and from work on media production by young people. Some conclusions were drawn about the position of the work in relation to existing models of curriculum activity in the light of the range of sophisticated and rich representations made by the children in their media text

Planning: Applied Rationality or Contingent Practice?

This paper develops an interactional approach to planning in organisations that draws out the relevance of both rationalist and contingent models of planning. The distinction between these two models is developed in the light of the modernist / postmodernist debate to provide a set of theoretical issues to with planning in organisations. These issues are explored in the context of planning carried out in two empirically studied settings, a health authority and a school. The two models are found to provide resources for organisations and participants in these settings, both to proceed with planning activity and to account for it. Neither model is however adequate to describe the process of planning which is always a practical and situated activity whose character emerges in the process of interaction

Towards metropolitan regionalism. Stuttgart and Rome: two models in comparison

The process of “metropolisation” that has characterized the development of urbanization in contemporary cities over the last few decades, is being subjected to a transformation process oriented towards “regionalization” dynamics, where metropolitan regions become the engines of economic development and competitiveness on an international scale. The objective of a comparison between the experience of the Stuttgart region and that of metropolitan Rome, the largest municipality in Europe, is to contrast an example of an efficient, democratic and dynamic regional government with the difficulties in administering a territory as complex as Rome, in an institutional and political framework that does not tend to foster chances of constituting new government models at a supra-municipal scale

Design for manufacture and sustainability in new product development

Design for manufacture is well recognised by industry and is about optimising design to aid production. Today there is a significant and growing trend of recognising what happens to a product once its user phase has finished. Post-consumer processes are now an important consideration during the ab-initio stages of design. Rather than a focus limited to design for manufacture or (more recently) design for assembly now the pressure is on for post consumer design. Companies need to do this because legislative pressures are increasing and consumers are becoming ever more aware of, and concerned about, environmental issues. End-of-life processing and design for the environment are therefore areas of growing of interest. This conference paper investigates with industry practitioners their experiences regarding for both the environmental and economic advantages of product life-cycle planning. Legislative pressures and consumer awareness are driving businesses to develop sustainable product design strategies (Jones et al, 2001 p. 27). Changes within the law, to protect our environment, cause companies to pay attention as they begin to affect profitability. The first British Standard to address design for end-of-life processing, and therefore support industry, is BS 8887-1. Over 60 UK manufacturing and design companies that had bought BS 8887-1 contributed to this by being interviewed or providing a written response. The research investigated multiple aspects of sustainable design in practice however, in this conference paper the focus is its application within the design process

Developing a frame of reference for ex-ante IT/IS investment evaluation

Investment appraisal techniques are an integral part of many traditional capital budgeting processes. However, the adoption of Information Systems (IS) and the development of resulting infrastructures are being increasingly viewed on the basis of consumption. Consequently, decision-makers are now moving away from the confines of rigid capital budgeting processes, which have traditionally compared IS with non-IS-related investments. With this in mind, the authors seek to dissect investment appraisal from the broader capital budgeting process to allow a deeper understanding of the mechanics involved with IS justification. This analysis presents conflicting perspectives surrounding the scope and sensitivity of traditional appraisal methods. In contributing to this debate, the authors present taxonomies of IS benefit types and associated natures, and discuss the resulting implications of using traditional appraisal techniques during the IS planning and decision-making process. A frame of reference that can be used to navigate through the variety of appraisal methods available to decision-makers is presented and discussed. Taxonomies of appraisal techniques that are classified by their respective characteristics are also presented. Perspectives surrounding the degree of involvement that financial appraisal should play during decision making and the limitations surrounding investment appraisal techniques are identifie
