Discovering discovery tools
Authors: James Dean , Garrett Michael , Krevit Leah 
Published: June 2009

PurposeMany libraries are now designing and implementing their own tools to meet users' needs for search and data discovery. The aim of this study is to share the experiences of the HAM‐TMC Library, one of the largest US medical libraries, in creating and implementing such a tool.Design/methodology/approachA narrative of the process demonstrates the genesis of the project and highlights the importance of collaboration with entities outside the usual library sphere.FindingsResults show that libraries have choices to make in designing their own futures and in offering innovative services to their users. Taking a proactive approach can yield exciting results.Originality/valueMany libraries accept federated search and other technologies directly from their library management system vendors as the simplest way to proceed with implementing new technologies. The HAM‐TMC Library recognized that its particular information environment required learning the “problem space” thoroughly before investigating available options. As a result, the new tool the Library is providing is much more likely to meet specific user information needs.
YAZ proxy installation to enhance Z39.50 server performance
Authors: Dixson Larry E. 
Published: June 2009

PurposeThe purpose of this article is to promote the usage of an open‐source gateway product that will enhance the functionality of a Z39.50 server that is maintained by a third‐party vendor.Design/methodology/approachThe required functionality improvements, needed by the LC Z39.50 server (i.e. the problems LC needed to solve) will be listed and described. Possible approaches to solving the problems will be listed. The selected open‐source gateway product and its features will be described. A possible instance of the product's configuration file will be provided and annotated.FindingsIt is possible for many third‐party server problems to be corrected or controlled even if the server application is not accessible by vendor APIs. LC was able to do this by installing the YAZ Proxy, a product that is both a Z39.50‐to‐Z39.50 gateway and an SRU‐to‐Z39.50 gateway. The proxy provides a way to filter and sanitize problematic Z39.50 requests, and it also allows the ILS system server to support retrieval of XML records and to support access via an XML‐based search protocol. Dramatic system performance improvements resulted from the installation of this product.Originality/valueThe paper describes an inexpensive way to provide performance improvements to a ILS system Z39.50 server and to provide enhancements that allow XML retrieval of MARC records and the support of an XML‐based search protocol.
Crossing the IT hurdle: a practical approach to implementing records management technology
Authors: Vednere Ganesh 
Published: June 2009

PurposeThe purpose of this paper is to describe the challenges of implementing a records management system in an ever changing business, regulatory and operational landscape and to suggest remediation measures.Design/methodology/approachThe approach is based on the author's experiences of implementing large scale enterprise‐wide content and records management systems. Practical advice is provided on key measures to be undertaken to mitigate the challenges of implementing records management systems.FindingsThe key findings highlight that records managers must have a deep understanding of the business/regulatory environment, technology landscape and the organizational culture. The challenge of managing records in multiple applications, different platforms and varying formats coupled with constantly changing business, regulatory and technology environments is not easy. By properly planning the design and development of the technology system, one can look forward to a well received used records management programme.Practical implicationsThe paper describes the challenges facing records managers in implementing a technology solution and highlights key areas that records managers need to focus on during the implementation lifecycle and describe key lessons learnt.Originality/valueThe paper is beneficial to information and compliance managers who are looking to automate the task of records and information management by providing key considerations prior to and during the implementation of large scale enterprise wide technology systems. It provides valuable insight and key points that must be discussed by any implementation team prior to embarking upon a major records management systems initiative.
Implementing a managed learning environment in the NHS
Authors: Gray Sue , Plaice Caroline , Hadley Sharon 
Published: June 2009

PurposeThe purpose of this case study is to detail the implementation of a managed learning environment (MLE) in a large National Health Service (NHS) Trust employing 8,500 staff. It aims to be of use to those seeking to implement a virtual or managed learning environment within their organisation and to help in reflecting on the project so far and to learn lessons to support the implementation of a national MLE for the NHS.Design/methodology/approachThe paper is based on the practical experiences and challenges of implementing an organisation wide system, reflecting candidly on the successes and failures of such a project.FindingsThe success of the MLE implementation is to a large degree based on the quality of the legacy data, and of the ability of the organisation to respond to changes in the way data are collected and processed. The ability of a supplier to work with a large and complex organisation is also a critical success factor, yet it is difficult to assess this suitability through comparison with other large organisations.Practical implicationsThe authors' experiences are transferable and there are a number of key messages which will be of use to other implementers. The findings in relation to the way data are collected and processed have highlighted and in some cases suggested ways forward to improve how records are managed locally.Originality/valueAs blended learning in both public and private sectors increases in popularity, the planning and implementation of systems able to accurately reflect training needs and achievements is vital, yet the reality is that these systems often rely at the outset on poor legacy data. The authors are not aware of another article in this genre in the UK.
An evaluation of MoReq2 in the context of national EDRMS standard developments in the UK and Europe
Authors: Wilhelm Philipp 
Published: June 2009

PurposeThe purpose of this paper is to show the differences between European Electronic Document and Records Management System (EDRMS) standards in Europe with special focus on MoReq2 and TNA 2002 and to explore the benefits and problems of superseding national standards by a European model.Design/methodology/approachInterviews were conducted with 18 key stakeholders from across Europe. The qualitative method was chosen for the open‐ended interviews.FindingsThere is a wide range of opinions on national and European standards. MoReq2 is widely valued as a comprehensive and modern standard. Some interviewees indicated that the standard did create a culture of overregulation and was too detailed. Market impact depends on the compliance testing regime and legislation.Originality/valueWithin the field of EDRMS standards there has been limited research. This paper presents the first comparison of TNA 2002 and MoReq2. In addition it evaluates the economic impact EDRMS standards can have on vendors and users of these systems.
Towards establishing a framework for managing trusted records in the electronic environment
Authors: Ismail Aliza , Jamaludin Adnan 
Published: June 2009

PurposeThe purpose of this paper is to attempt to establish a framework for managing trusted records in the electronic environment.Design/methodology/approachThe study collates the criteria required to manage trusted electronic records through the available literature and best practice and tests these on experts through an opinion survey. The study was done via email inviting 40 selected experts (18 participated), known in the fields of records and archives management all over the world, to respond to a structured framework of managing electronic records.FindingsThe findings indicate that the experts are unanimously agreed that the five main contexts, namely governance, recordkeeping, archival, technological, skills and competency, serve as an audit list providing the trusted environment for managing records in the electronic environment.Research limitations/implicationsThe collation of the criteria for trusted electronic records management, based on available literature and best practice in the field, may not be exhaustive as new literature on the latest information and knowledge, debates and practices continues to emerge throughout the records and archives community.Practical implicationsThe study's findings are significant in confirming that the criteria collated are highly recommended and crucial in ensuring the reliability, authenticity, integrity and long term accessibility of electronic records.Originality/valueThe study establishes the elements in building trusted management of electronic records. This framework provides a basis for good records management practices to ensure that electronic records are to be managed in an efficient and consistent manner. This is vital for the long‐term preservation of those records with continuing value or as the evidence of transactions and the accountability that the records held for their current use.
Segmenting consumers for food defense communication strategies
Authors: Degeneffe Dennis , Kinsey Jean , Stinson Thomas , Ghosh Koel 
Published: June 2009

PurposeIn the light of lessons learned from recent disasters (The London subway bombings, and Hurricane Katrina), it has become increasingly clear that supply chain partners as well as government agencies need to be prepared to communicate effectively to consumers and customers before, during and after a disaster. Effective communication can minimize confusion and harm to company reputations, to consumers, the economy and the nation. Incorporating consistent communications into supply chain management (SCM) plans used by all parties in the supply chain will enhance competitiveness of the whole chain and speed recovery from potentially disastrous events. Findings from a national survey of consumer's attitudes about terrorism provide information about the development of targeted and effective communications.Design/methodology/approachBased on a survey of more than 4,000 US consumers, this study used “predictive segmentation” which consists of a canonical factor analysis relating general consumer attitudes and values to their more specific fears and concerns about terrorism. A clustering of consumers then identifies six diverse consumer segments providing a framework for the development of communication strategies.FindingsResults from this study demonstrate that people can be grouped based on their general attitudes and values in such a way that their diversity can be captured in a simple framework of segments each reflecting striking differences in the level of concern over potential terrorist attacks.Practical implicationsGuidance is offered for the development of communication strategies based on the information needs and media behavior of each consumer segment to mitigate the impact of a potential terrorist attack or catastrophic food safety breaches. It provides practical and logical extension of former studies that suggest incorporating consumers, attitudes into SCM and business continuity plans.Originality/valueThis study leverages a common and proven marketing research approach – segmentation – used in private industry for the marketing of goods and service. It applies this method to defining segments of consumers based on their attitudes and concerns about terrorism that will be useful in supply chain communication management.
Improving bid pricing for humanitarian logistics
Authors: Trestrail John , Paul Jomon , Maloni Michael 
Published: June 2009

PurposeHumanitarian logistics plays a critical role in the aid response to hunger and disasters worldwide. The US Department of Agriculture (USDA) uses a competitive bidding process to procure P.L. 480 Title II food aid, a $2 billion business annually. This paper describes a mixed‐integer program (MIP) decision tool that mimics the USDA bid approach in order to improve ocean carrier and food supplier bid pricing strategy.Design/methodology/approachFirst, the USDA bid process is detailed and the MIP decision tool is described. Then how the tool is run against historical data to approximate future USDA bid awards is explained, allowing the authors to subsequently advise food supplier and ocean carrier clients of expected price competition and pricing flexibility before they submit bids.FindingsThe MIP decision tool has demonstrated its effectiveness in supporting $8 million in food aid bids. Bidding implications for food aid carriers and suppliers are provided as well as suggestions for additional opportunities for humanitarian logistics research are offered.Originality/valueExtant literature in procurement offers little practical support for bidder pricing preparation. Additionally, humanitarian logistics is an emerging, under‐researched field, and this paper is the first to address sourcing and distribution of Title II food aid.
Non‐equilibrium viscous shock‐layer technique for computing hypersonic flow around blunt‐nosed slender bodies
Authors: Ghasemloo S. , Mani M. 
Published: June 2009

PurposeThe purpose of this paper is to present a non‐equilibrium viscous shock layer (VSL) solution procedure that considerably improves computational efficiency, especially for long slender bodies.Design/methodology/approachThe VSL equations are solved in a shock oriented coordinate system. The method of solution is spatial marching, implicit, finite‐difference technique, which includes coupling of the normal momentum and continuity equations. In the nose region, the shock shape is specified from an algebraic expression and corrected through global passes through that region. The shock shape is computed as part of the solution beyond the nose region and requires only a single global pass. For this study, a seven‐species (O2, N2, O, N, NO, NO+, e−) air model is used.FindingsThe present approach eliminates the need for initial shock shape, which was required by previous method of solution. This method generates its own shock shape as a part of solution and the input shock shape obtained from a different solution is not required. Therefore, in comparison with the other VSL methods, the present approach dramatically reduces the CPU time of calculations. Moreover, by using the shock oriented coordinate systems the junction point problem in sphere‐cone configurations is solved.Practical implicationsThis method is an excellent tool for parametric study and preliminary design of hypersonic vehicles.Originality/valueThe present method provides a computational capability which reduces the CPU time, and expands the range of application for the prediction of hypersonic heating rates.
Thermophoresis particle deposition – thermal radiation interaction on natural convection heat and mass transfer from vertical permeable surfaces
Authors: Duwairi H.M. , Damseh Rebhi. A. 
Published: June 2009

PurposeThe purpose of this paper is to study thermophoresis particle deposition and thermal radiation interaction on natural convection heat and mass transfer by steady boundary layer flow over an isothermal vertical flat plate embedded in a fluid saturated porous medium.Design/methodology/approachThe governing partial differential equations are transformed into non‐similar form by using special transformation and then the resulting partial differential equations are solved numerically by using an implicit finite difference method.FindingsDifferent results are obtained and displaced graphically to explain the effect of various physical parameters on the wall thermophoresis deposition velocity and concentration profiles. It is found that the increasing of thermal radiation parameter or dimensionless temperature ratio heats the fluid and decreases temperature gradients near permeable wall, which increases local Nusselt numbers and decreases wall thermophoresis velocities. It is also found that the effect of power indices of either temperatures or concentration enhances both local Nusselt numbers and wall thermophoresis velocities. Comparison with previously published work in the limits shows excellent agreement.Originality/valueThe paper presents useful conclusions based on graphical results obtained from studying numerical solutions for thermophoresis‐thermal radiation heat and mass transfer interaction by steady, laminar boundary layer over a vertical flat plate embedded in a porous medium.
Flow over solid blocks in open ended cavity
Authors: Shuja S.Z. , Yilbas B.S. , Khan S.M.A. 
Published: June 2009

PurposeThe purpose of this paper is to consider flow over heat generating bodies in an open‐ends cavity, which finds applications in electronics cooling and industrial processing. Heat transfer rates depend on the flow situation in the cavity, which is influenced by the cavity inlet and exit port locations, heat transferring body size and its orientation in the cavity, and the cavity size. Consequently, modeling of flow over heat transferring bodies in an open‐ends cavity and examination of the effect of the aspect ratio and orientation of the heat transferring bodies on the flow field and heat transfer rates becomes essential.Design/methodology/approachThe flow over heat generating solid blocks situated in an open‐ends cavity is considered and the effects of blocks' orientations and aspect ratios on flow field as well as heat transfer rates are examined. A numerical scheme using a control volume approach is introduced to predict flow field in the cavity and heat transfer rates from the blocks.FindingsIt is found that complex flow structure is generated in the cavity due to the aspect ratios and orientations of the blocks. This, in turn, influences significantly heat transfer rates from the blocks in the cavity.Research limitations/implicationsSurface areas of blocks are kept the same and aspect ratio is varied such that the surface area of each block remains the same in the simulations. In addition, Steady flow situation is considered for governing equations of flow and heat transfer in the cavity. However, for the future study transient heating and flow situations can be considered while varying the surface araes of the blocks. This will provide useful information on the circulations in the cavity and the enhancement of heat transfer due to the complex flow structure.Practical implicationsIn practice, cooling effectiveness can be improved through changing the aspects ratio of the heat generating bodies in the cavity.Originality/valueThe findings are original and will be useful for the scientists and the design engineers working the specific area of heat transfer and fluid flow.

Authors: Varol Yasin , Oztop Hakan F. , Pop Ioan 
Published: June 2009

PurposeThe purpose of this paper is to study the conjugate heat transfer via natural convection and conduction in a triangular enclosure filled with a porous medium.Design/methodology/approachDarcy flow model was used to write governing equations with Boussinesq approximation. The transformed governing equations are solved numerically using a finite difference technique. It is assumed that the enclosure consists of a conducting bottom wall of finite thickness, an adiabatic (insulated) vertical wall and a cooled inclined wall.FindingsFlow patterns, temperature and heat transfer were presented at different dimensionless thickness of the bottom wall, h, from 0.05 to 0.3, different thermal conductivity ratio between solid material and fluid, k, from 0.44 to 283 and Rayleigh numbers, Ra, from 100 to 1000. It is found that both thermal conductivity ratio and thickness of the bottom wall can be used as control parameters for heat transport and flow field.Originality/valueIt is believed that this is the first paper on conduction‐natural convection in porous media filled triangular enclosures with thick wall. In the last years, most of the researchers focused on regular geometries such as rectangular or square cavity bounded by thick wall.
Pressure drop caused by two‐phase flow of oil/water emulsions through sudden expansions and contractions: a computational approach
Authors: Roul Manmatha K. , Dash Sukanta K. 
Published: June 2009

PurposeThe purpose of this paper is to compute the pressure drop through sudden expansions and contractions for two‐phase flow of oil/water emulsions.Design/methodology/approachTwo‐phase computational fluid dynamics (CFD) calculations, using Eulerian–Eulerian model, are employed to calculate the velocity profiles and pressure drops across sudden expansions and contractions. The pressure losses are determined by extrapolating the computed pressure profiles upstream and downstream of the expansion/contraction. The oil concentration is varied over a wide range of 0‐97.3 percent by volume. The flow field is assumed to be axisymmetric and solved in two dimensions. The two‐dimensional equations of mass, momentum, volume fraction and turbulent quantities along with the boundary conditions have been integrated over a control volume and the subsequent equations have been discretized over the control volume using a finite volume technique to yield algebraic equations which are solved in an iterative manner for each time step. The realizable per phase k‐ ε turbulent model is considered to update the fluid viscosity with iterations and capture the individual turbulence in both the phases.FindingsThe contraction and expansion loss coefficients are obtained from the pressure loss and velocity data for different concentrations of oil–water emulsions. The loss coefficients for the emulsions are found to be independent of the concentration and type of emulsions. The numerical results are validated against experimental data from the literature and are found to be in good agreement.Research limitations/implicationsThe present computation could not use the surface tension forces and the energy equation due to huge computing time requirement.Practical implicationsThe present computation could compute realistically the two‐phase pressure drop through sudden expansions and contractions by using a two‐phase Eulerian model and hence this model can be effectively used for industrial applications where two‐phase flow comes into picture.Originality/valueThe original contribution of the paper is in the use of the state‐of‐the‐art Eulerian two‐phase flow model to predict the velocity profile and pressure drop through industrial piping systems.
