Hydro-thermal generation unit commitment and dispatch using a dynamic programming approach

The problem of thermal unit commitment is solved with dynamic programming. A practical example is given which solves the problem for a six generator system over a one year time span. This long range solution is used with a hydro optimization procedure to give an optimized hydro-thermal unit commitment solution. From this, a worth of hydro value is computed for each month, which may be used in the daily dispatching of thermal units and hydro. Applications of the program are also shown for aiding in generator maintenance scheduling and evaluating purchase power contracts with neighboring utilities. Error analysis is made with respect to errors in system load forecasting and forced generator outages --Abstract, page ii

Developing a Culture of Publication: a joint enterprise writing retreat

Purpose: Many students irrespective of level of study produce excellent course work which, if given support and encouragement could clearly be of a publishable standard. Academic staff are expected to produce quality publications meeting peer review standards although they may be relatively novice authors. All are engaged in some aspects of academic writing practices but not as frequently involved in co-production of publications emanating from student work. This activity is still at the margins of much of the student experience. Design/methodology: Mindful of these issues, we designed and offered a writing programme including a writing retreat. This brought together undergraduate and postgraduate students from a range of applied disciplines (health and art, design and architecture) and their supervisors with the aim of co-producing publications and participating in a community of scholarly practice. The project was delivered over nine months. It involved four days ‘compulsory’ attendance and included a preparatory workshop, a two day off campus writing retreat and a dissemination event. Student and supervisors applied to participate as a team. Kirkpatrick’s (2006) four-stage classic model: reaction, learning, changes in behaviour and real world results was used as a framework for the educational evaluation. Key findings organised thematically were: Supervisor-supervisee relationships; space and time; building confidence enabling successful writing and publication. Originality/Value: This paper will provide an overview of the design, content and approaches used for successful delivery of this innovative project. It will draw on examples that illustrate the different types of joint enterprise that emerged, illuminate experiences of co-production and co-authorship along with recommendations for future ventures

Public libraries, museums and physical convergence. Context, issues, opportunities: a literature review. Part 2

There has recently been a growth in physical convergence in cultural heritage domains. The second of a two-part article that considers this trend with particular regard to public libraries and museums provides an overview of factors to be considered by those planning or developing physically converged services. This has been achieved through thematic analysis of a review of international literature from both domains. It begins with consideration of obstacles to convergence, ethical challenges, organisational and strategic complexity, organisational culture and resistance. It moves on to discuss factors, general and physical, that can lead to success in convergence: vision, strategy and planning, communication and trust, for example, and, how these can be led and managed. It also considers the role of professional education and training, the benefits of convergence, for example, improved cultural offer and visibility, financial savings, with viewpoints from around the world. Part 2 ends with a critical note on the ‘convergence narrative’, and a conclusion that focuses on physical convergence which draws on both Parts

Public libraries, museums and physical convergence: Context, issues, opportunities: A literature review Part 1

There has recently been a growth in physical convergence in cultural heritage domains. Part 1 examines this ‘trend’, its drivers and related issues, with particular focus on public libraries and museums. It offers an overview of practice, challenges and opportunities. Through thematic analysis of a comprehensive, literature review of both domains that looked at the wider aspects of collaboration, cooperation, partnerships and integration in the sector as well as physical convergence, it provides insight into background, theory and activities worldwide. It presents discussion on the meaning of convergence, the concept of ‘memory institutions’, the relationship between public libraries and museums in the context of convergence, shared mission and values, convergence and re-convergence, and professionalism and divergence. It concludes with consideration of practical aspects such as motivations for convergence, including digital technology, changing user expectations and culture, and economic and political challenges that impact on physical convergence in a dynamic local government environment

Are randomised controlled trials positivist? Reviewing the social science and philosophy literature to assess positivist tendencies of trials of social interventions in public health and health services.

BACKGROUND: We have previously proposed that trials of social interventions can be done within a "realist" research paradigm. Critics have countered that such trials are irredeemably positivist and asked us to explain our philosophical position. METHODS: We set out to explore what is meant by positivism and whether trials adhere to its tenets (of necessity or in practice) via a narrative literature review of social science and philosophical discussions of positivism, and of the trials literature and three case studies of trials. RESULTS: The philosophical literature described positivism as asserting: (1) the epistemic primacy of sensory information; (2) the requirement that theoretical terms equate with empirical terms; (3) the aim of developing universal laws; and (4) the unity of method between natural and social sciences. Regarding (1), it seems that rather than embodying the epistemic primacy of sensory data, randomised controlled trials (RCTs) of social interventions in health embrace an anti-positivist approach aiming to test hypotheses derived deductively from prior theory. Considering (2), while some RCTs of social interventions appear to limit theorisation to concepts with empirical analogues, others examine interventions underpinned by theories engaging with mechanisms and contextual contingencies not all of which can be measured. Regarding (3), while some trialists and reviewers in the health field do limit their role to estimating statistical trends as a mechanistic form of generalisation, this is not an inevitable feature of RCT-based research. Trials of social interventions can instead aim to generalise at the level of theory which specifies how mechanisms are contingent on context. In terms of (4), while RCTs are used to examine biomedical as well as social interventions in health, RCTs of social interventions are often distinctive in using qualitative analyses of data on participant accounts to examine questions of meaning and agency not pursued in the natural sciences. CONCLUSION: We conclude that the most appropriate paradigm for RCTs of social interventions is realism not positivism

Information Systems and the Problem of Work: Protocol for a Systematic Review

There is a sense in America that there is a growing crisis regarding the availability or quality of rewarding, satisfying work. A variety of competing framings of and reasons for this are offered, including some claims that information technologies and systems are to blame for the decline in work satisfaction. A number of streams of research in diverse disciplines have sought to understand what constitutes good , or meaningful , or decent work, how we can achieve it, and what happens when it is lacking, yet we know little about what contributions the information systems discipline has made, or could make, to solving this challenge of our times. In this paper we chart the conceptual landscape of the problem of work as it is framed by reference disciplines, and develop a protocol for a systematic literature review of contributions from IS research to creating good work or making work better
