Abstract

The third and last in a series on Open Archives Initiative data providers. This article focuses on the social sciences and humanities, specifically on the David Rumsey Historical Map Collection ‐ a collection which includes atlases, globes, school geographies, books, maritime charts and a variety of separate maps, primarily (but not exclusively) of the Americas from the eighteenth and nineteenth centuries..

Abstract

Considers a systems model of changes in industrial structure, employment and income levels. A country subsidizes imported resources to augment its existing resource base and to develop an export promotion strategy. This is leveraged with borrowed money. According to neo‐classical economic theory, factors of production are paid in proportion to their output contribution. Economic growth occurs when the return from a higher rate of factor utilization exceeds the cost of subsidization. In the study of ordinary differential equations, simultaneous changes in variables can be treated as part of a dynamic system subject to constraints. At any moment resources are fixed, and we may assume D'Alembert's principle of virtual work with respect to the internal constraints of the system. Subsidized economic growth shares a paradigm with analytical dynamics, the stability of motion around the neighbourhood of a singular point. The classical analytical‐topological methods which describe asymptotic stability are used to investigate economic policy.

Abstract

Purpose

The purpose of this paper is to consider how digital resources might best be created and how the digital medium might best be exploited to serve the needs of research and teaching in the humanities.

Design/methodology/approach

The history of text‐based humanities computing is traced to illustrate the complexity of humanities sources and the requirements for their representation in digital form.

Findings

The paper finds that digital information is completely different from any other kind of information, being dynamic, extensible and manipulable in many different ways. It is not static and it can be manipulated in many different ways. The Extensible Markup Language (XML) has been widely adopted in the humanities particularly for full text sources encoded according to the Text Encoding Initiative application. XML permits the display, analysis and manipulation of fine detail within a document. It also facilitates the chunking of information and the integration of data and metadata leading to new forms of publication that exploit the digital medium to the full.

Research limitations/implications

The research environment proposed in this paper challenges current modes of working with a more innovative approach to the nature and functionality of digital representations of humanities sources.

Originality/value

The paper looks at the development of humanities computing and should be helpful for anyone embarking on or managing a humanities digital project.

Abstract

Purpose

The purpose of this paper is to evaluate Help features in digital libraries and identify problems related to their design.

Design/methodology/approach

This study selects six digital libraries to represent a variety of digital libraries developed or sponsored by different types of organisations. The Help features of these selected digital libraries are examined by their types (explicit versus implicit), formats (texts, images, screenshots, multimedia materials, and interactive formats), and presentation styles (descriptive, guided, procedural, and exemplary).

Findings

This study presents the types of Help features available in the selected digital libraries, and further characterises the formats and presentation styles of these Help features. In the process of analysis, the author also identifies six types of problems: lack of standards; tradeoff between using explicit Help and implicit help; tradeoff between using general Help versus specific Help; lack of interactive Help features; lack of dynamic presentation styles; and lack of Help features for advanced users and users who do not understand English.

Research limitations/implications

In order to design Help features that facilitate users to effectively use digital libraries, further research needs to extend studies to what types of help‐seeking situations users generally encounter and the corresponding support they need.

Originality/value

This study provides insightful information regarding the current status and problems of the Help features in existing digital libraries.

Abstract

Purpose

With the growing deployment of variable renewable energy sources, such as wind and PV and the increasing interconnection of the power grid, multi-regional energy system models (ESMs) are increasingly challenged by the growth of model complexity. Therefore, the need for developing ESMs, which are realistic but also solvable with acceptable computational resources without losing output accuracy, arises. The purpose of this study is to propose a statistical approach to investigate asynchronous extreme events for different regions and then assess their ability to keep the output accuracy at the level of the full-resolution case.

Design/methodology/approach

To extract the extreme events from the residual demands, the paper focuses on analyzing the tail of the residual demand distributions by using statistical approaches. The extreme events then are implemented in an ESM to assess the effect of them in protecting the accuracy of the output compared with the full-resolution output.

Findings

The results show that extreme-high and fluctuation events are the most important events to be included in data input to maintain the flexibility output of the model when reducing the resolution. By including these events into the reduced data input, the output's accuracy reaches the level of 99.1% compared to full resolution case, while reducing the execution time by 20 times.

Originality/value

Moreover, including extreme-fluctuation along with extreme-high in the reduced data input helps the ESM to avoid misleading investment in conventional and low-efficient generators.

Abstract

The Library of Congress (LC) was an early adopter of the OAI Protocol for Metadata Harvesting. The protocol allows LC to make digitized historical collections available for integration into other services. The protocol was straightforward to implement and the harvesting traffic has no perceptible effect on the primary users of the American Memory project. Now that services can integrate records for cultural heritage resources from many sources, it is time to build on that experience to develop better services. How should the scarce resources available to produce metadata be deployed to most advantage to support discovery in different contexts? How might metadata harvesting be exploited to support new interfaces and enhanced navigation among related resources in digital libraries? This article starts a conversation between metadata providers and service builders by describing LC’s experience and questions that have surfaced.

Theoretical reconstruction for the sake of deeper and clearer understanding of an important theme in classical philosophy (aporia/euporia)

Abstract

Purpose

Theoretical reconstruction for the sake of deeper and clearer understanding of an important theme in classical philosophy (aporia/euporia)

Methodology/approach

Logical critique (and reconstruction); aporetic and euporetic logic.

Findings

Using key texts by Plato and Aristotle on aporia and euporia, I attempt to show that Derrida’s, and more broadly deconstructive, readings are problematic and require careful and critical reconsideration.

Research limitations

A full account of aporia in the work of Derrida is beyond the scope of the paper – so too is a full account of aporia and euporia in the works of Plato and Aristotle.

Practical implications

The paper has important implications in terms of our reading and interpretation of important classical texts such as Aristotle’s Metaphysics.

Originality/value

The paper builds on important research by philosophers like Matthews and on the nature and role of aporia in classical philosophy, just as it extends the author’s own critique of deconstructive appropriations of aporia. It argues for the importance of reconstructing our understanding of aporetic and euporetic thinking in order to see it more clearly especially in its classical forms, contexts and frameworks.
