Personalisation and recommender systems in digital libraries

Widespread use of the Internet has resulted in digital libraries that are increasingly used by diverse communities of users for diverse purposes and in which sharing and collaboration have become important social elements. As such libraries become commonplace, as their contents and services become more varied, and as their patrons become more experienced with computer technology, users will expect more sophisticated services from these libraries. A simple search function, normally an integral part of any digital library, increasingly leads to user frustration as user needs become more complex and as the volume of managed information increases. Proactive digital libraries, where the library evolves from being passive and untailored, are seen as offering great potential for addressing and overcoming these issues and include techniques such as personalisation and recommender systems. In this paper, following on from the DELOS/NSF Working Group on Personalisation and Recommender Systems for Digital Libraries, which met and reported during 2003, we present some background material on the scope of personalisation and recommender systems in digital libraries. We then outline the working group’s vision for the evolution of digital libraries and the role that personalisation and recommender systems will play, and we present a series of research challenges and specific recommendations and research priorities for the field

Land Use Strategy (LUS) Delivery Evaluation Project : Volume 1: Main Report

Scotland’s first Land Use Strategy (LUS) – Getting the best from our land – was published in March 2011. The LUS is a requirement of the Climate Change (Scotland) Act 2009, highlighting the important contribution that Scottish Ministers expect land use and land management to make towards the climate change agenda in Scotland. The crucial component of the LUS are its ten principles for sustainable land use – the LUS Principles. The LUS Principles are the key mechanism by which the strategic intent of the national level LUS can be translated into regional and local level planning and decision-making, through existing land use delivery mechanisms, to inform action on the ground. The overall aim of the LUS Delivery Evaluation Project therefore was “to evaluate the range of current land use delivery mechanisms, to ascertain their effectiveness in translating the strategic Principles of the LUS into decision-making on the ground”. The evaluation considered eleven case study land use delivery mechanisms ranging from an urban Local Development Plan (LDP) to the Loch Lomond and the Trossachs National Park Partnership Plan

Prioritizing Invasive Species Threats Under Uncertainty

Prioritizing exotic or invasive pest threats in terms of agricultural, environmental, or human health damages is an important resource allocation issue for programs charged with preventing or responding to the entry of such organisms. Under extreme uncertainty, program managers may decide to research the severity of threats, develop prevention or control actions, and estimate cost-effectiveness in order to provide better information and more options when making decisions to choose strategies for specific pests. We examine decision rules based on the minimax and relative cost criteria in order to express a cautious approach for decisions regarding severe, irreversible consequences, discuss the strengths and weaknesses of these rules, examine the roles of simple rules and sophisticated analyses in decision making, and apply a simple rule to develop a list of priority plant pests.invasive species, decision criteria, uncertainty, Resource /Energy Economics and Policy,

Building self-optimized communication systems based on applicative cross-layer information

This article proposes the Implicit Packet Meta Header(IPMH) as a standard method to compute and represent common QoS properties of the Application Data Units (ADU) of multimedia streams using legacy and proprietary streams’ headers (e.g. Real-time Transport Protocol headers). The use of IPMH by mechanisms located at different layers of the communication architecture will allow implementing fine per-packet selfoptimization of communication services regarding the actual application requirements. A case study showing how IPMH is used by error control mechanisms in the context of wireless networks is presented in order to demonstrate the feasibility and advantages of this approach

Human Factors Standards and the Hard Human Factor Problems: Observations on Medical Usability Standards

With increasing variety and sophistication of computer-based medical devices, and more diverse users and use environments, usability is essential, especially to ensure safety. Usability standards and guidelines play an important role. We reviewed several, focusing on the IEC 62366 and 60601 sets. It is plausible that these standards have reduced risks for patients, but we raise concerns regarding: (1) complex design trade-offs that are not addressed, (2) a focus on user interface design (e.g., making alarms audible) to the detriment of other human factors (e.g., ensuring users actually act upon alarms they hear), and (3) some definitions and scope restrictions that may create “blind spots”. We highlight potential related risks, e.g. that clear directives on “easier to understand” risks, though useful, may preclude mitigating other, more “difficult” ones; but ask to what extent these negative effects can be avoided by standard writers, given objective constraints. Our critique is motivated by current research and incident reports, and considers standards from other domains and countries. It is meant to highlight problems, relevant to designers, standards committees, and human factors researchers, and to trigger discussion about the potential and limits of standards

Handling Data-Based Concurrency in Context-Aware Service Protocols

Dependency analysis is a technique to identify and determine data dependencies between service protocols. Protocols evolving concurrently in the service composition need to impose an order in their execution if there exist data dependencies. In this work, we describe a model to formalise context-aware service protocols. We also present a composition language to handle dynamically the concurrent execution of protocols. This language addresses data dependency issues among several protocols concurrently executed on the same user device, using mechanisms based on data semantic matching. Our approach aims at assisting the user in establishing priorities between these dependencies, avoiding the occurrence of deadlock situations. Nevertheless, this process is error-prone, since it requires human intervention. Therefore, we also propose verification techniques to automatically detect possible inconsistencies specified by the user while building the data dependency set. Our approach is supported by a prototype tool we have implemented.Comment: In Proceedings FOCLASA 2010, arXiv:1007.499

Digital transformation in the arts : a case study

This paper considers the interaction between digital technology and cultural organisations and the challenges and opportunities this presents for practice and for policy. The paper is based on one of eight 'digital R&D' projects supported by NESTA, Arts Council England and the AHRC, designed to analyse the effects of digital innovation in UK arts organisations. The paper focuses on a series of residencies in three UK arts organisations. The research aims to identify the cultural conditions which support or prevent short-term digital innovation becoming 'embedded' in the ongoing practice of a cultural organisation. The paper considers differing practices, attitudes and expectations between creative technologists and arts organisations. These differing 'cultures of innovation' may help us to understand why digital innovations often fail to move beyond temporary and pragmatic problem-solving towards more challenging, transformational effects on organisational strategy and culture

Climate-ready conservation objectives: a scoping study

AbstractAnticipated future climate change is very likely to have a wide range of different types of ecological impact on biodiversity across the whole of Australia. There is a high degree of confidence that these changes will be significant, affecting almost all species, ecosystems and landscapes. However, because of the complexity of ecological systems and the multiple ways climate change will affect them, the details of the future change are less certain for any given species or location. The nature of the changes means that the multiple ways biodiversity is experienced, used and valued by society will be affected in different ways. The likely changes present a significant challenge to any societal aspiration to preserve biodiversity in its current state, for example, to maintain a species in its current abundance and distribution. Preserving biodiversity ‘as is’ may have been feasible in a stationary climate (one that is variable but not changing), but this will not be possible with the widespread, pervasive and large ecological changes anticipated under significant levels of climate change. This makes the impacts of climate change quite unlike other threats to biodiversity, and they challenge, fundamentally, what it actually means to conserve biodiversity under climate change: what should the objectives of biodiversity conservation be under climate change? And what are the barriers to recalibrating conservation objectives?Based on key insights from the scientific literature on climate change and biodiversity, the project developed three adaptation propositions about managing biodiversity:Conservation strategies accommodate large amounts of ecological change and the likelihood of significant climate change–induced loss in biodiversity. Strategies remain relevant and feasible under a range of possible future trajectories of ecological change.Strategies seek to conserve the multiple different dimensions of biodiversity that are experienced and valued by society. Together these propositions summarise the challenge of future climate change for biodiversity conservation, and define a new way of framing conservation we called the ‘climate ready’ approach. In the near term, conservation strategies may be able to include some consideration of these propositions. However, under significant levels of climate change many of the current approaches to conservation will become increasingly difficult and ineffective (e.g. maintaining community types in their current locations). This challenge is fundamentally different from that posed by other threats to biodiversity, and the climate-ready approach is akin to a paradigm shift in conservation.The project used a review of 26 conservation strategy documents (spanning scales from international to local) and four case studies with conservation agencies to test and refine the climate-ready approach. The project found the approach to be robust and highly relevant; in the majority of situations, if adopted, it would lead to significant changes in the objectives and priorities of conservation. There were also many ‘green shoots’ of elements of the new approach in existing conservation practice. However, the project found there are currently substantial barriers to fully adopting a climate-ready approach. These include the need for: further development of ecological characterisation of ecosystem health and human activities in landscapesmuch better understanding of how society values different aspects of biodiversity, including ecosystems and landscapesdevelopment of policy tools to codify and implement new ecologically robust and socially endorsed objectives.  Anticipated future climate change is very likely to have a wide range of different types of ecological impact on biodiversity across the whole of Australia.
