A network-indexbased version of TOPMODEL for use with high-resolution digital topographic data

This paper describes the preliminary development of a network index approach to modify and to extend the classic TOPMODEL. Application of the basic Beven and Kirkby (1979) form of TOPMODEL to high resolution (2.0 m) laser altimetric data (based upon the U.K. Environment Agency’s Light Detection and Ranging (LIDAR) system) to a 13.8 km(2) catchment in an upland environment identified large areas of saturated areas that remained unconnected from the drainage network even during an extreme flood event. This is shown to be a particular problem with using high resolution topographic data especially over large spatial scales. To deal with the hydrological consequences of disconnected areas, we present a simple network index modification in which saturated areas only connect when the topographic index is sufficient for there to be zero or negative saturation deficits along a complete flow path. This is combined with an enhanced method for dealing with the problem of pits and hollows which is shown to become more acute with higher resolution topographic data. The paper concludes by noting the implications of the research as presented for both methodological and substantive research that is currently under way

Turning marketing promises into business value: The experience of an industrial SME

The article studies the value that businesses should have for their customers and shareholders. It explains how to develop such value to meet or exceed customer's expectations through the application of the promise framework. The promise model includes promises made to customers, promises kept, and promises that involve a synchronized effort from the whole firm to create and deliver value to customers

Specifying ODP computational objects in Z

The computational viewpoint contained within the Reference Model of Open Distributed Processing (RM-ODP) shows how collections of objects can be configured within a distributed system to enable interworking. It prescribes certain capabilities that such objects are expected to possess and structuring rules that apply to how these objects can be configured with one another. This paper highlights how the specification language Z can be used to formalise these capabilities and the associated structuring rules, thereby enabling specifications of ODP systems from the computational viewpoint to be achieved

A Combined EIS-NVSS Survey Of Radio Sources (CENSORS) III: Spectroscopic observations

The Combined EIS-NVSS Survey Of Radio Sources (CENSORS) is a 1.4GHz radio survey selected from the NRAO VLA Sky Survey (NVSS) and complete to a flux-density of 7.2mJy. It targets the ESO Imaging Survey (EIS) Patch D, which is a 3 by 2 square degree field centred on 09 51 36.0, -21 00 00 (J2000). This paper presents the results of spectroscopic observations of 143 of the 150 CENSORS sources. The primary motivation for these observations is to achieve sufficient spectroscopic completeness so that the sample may be used to investigate the evolution of radio sources. The observations result in secure spectroscopic redshifts for 63% of the sample and likely redshifts (based on a single emission line, for example) for a further 8%. Following the identification of the quasars and star-forming galaxies in the CENSORS sample, estimated redshifts are calculated for the remainder of the sample via the K-z relation for radio galaxies. Comparison of the redshift distribution of the CENSORS radio sources to distributions predicted by the various radio luminosity function evolution models of Dunlop & Peacock 1990, results in no good match. This demonstrates that this sample can be used to expand upon previous work in that field.Comment: Accepted for publication in MNRAS.

Signalling Intent: Beacons, Lookouts and Military Communications

Beacons and lookouts played a key role in the networks of local and regional communications of Anglo-Saxon England during the Viking Age (ninth to eleventh centuries). While the large fortified centres of the period are well known, the nature of interconnections between them and smaller-scale local arrangements have only recently received attention. Written evidence, place-names and landscape archaeology together allow for the reconstruction of elements of signalling and sighting systems. This contribution presents the historical evidence for beacons, discusses the context within which beacons and lookouts developed and draws upon a series of case studies to reveal local systems of communication in the landscape of Anglo-Saxon England

Identity in research infrastructure and scientific communication: Report from the 1st IRISC workshop, Helsinki Sep 12-13, 2011

Motivation for the IRISC workshop came from the observation that identity and digital identification are increasingly important factors in modern scientific research, especially with the now near-ubiquitous use of the Internet as a global medium for dissemination and debate of scientific knowledge and data, and as a platform for scientific collaborations and large-scale e-science activities.

The 1 1/2 day IRISC2011 workshop sought to explore a series of interrelated topics under two main themes: i) unambiguously identifying authors/creators & attributing their scholarly works, and ii) individual identification and access management in the context of identity federations. Specific aims of the workshop included:

• Raising overall awareness of key technical and non-technical challenges, opportunities and developments.
• Facilitating a dialogue, cross-pollination of ideas, collaboration and coordination between diverse – and largely unconnected – communities.
• Identifying & discussing existing/emerging technologies, best practices and requirements for researcher identification.

This report provides background information on key identification-related concepts & projects, describes workshop proceedings and summarizes key workshop findings

A Fisher-eye lens on social work reform

Summary Mark Fisher’s Capitalist Realism, published in 2009, has been recognised as one of the most important contributions chronicling the rise, application and consequences of neoliberalism. However, Fisher’s ideas have until now only garnered passing mention in the study of neoliberalism in children and families social work in England, despite there being extensive research, argument and publication on the subject more broadly. This article attempts to rectify this gap and apply Fisher’s theory to the recent reforms in children and families social work in England. Findings The article applies Fisher’s commentary on the co-option of language, invoking crisis, bureaucracy and proposing change to implement no change, to the reforms in children and families social work that began with the implementation of Reclaiming Social Work in 2008. Since that time, the original architects of Reclaiming Social Work have gained significant positions of power and influence and been instrumental in introducing neoliberal reforms throughout children and families social work in England. Applications Through applying the approach and concepts of Mark Fisher, this article concludes that it is possible to determine that the current reforms are, at their core, neoliberal in nature and driven by an ideological imperative to transform children and families social work in England into a neoliberal edifice, with less public sector and state input and oversight and an increase in the influence of ‘not-for-profits’, charities and international for-profit consultancies
