Highlights the elements of research into multiple retailers′ attitudes that relate to retail management with reference to shopping centres. Considers location, day‐to‐day management, and portfolio management. Concludes the retailers prefer high‐street locations, and have a space demand that can only be met by shopping centre developments, the emphasis for the 1990s being on re‐organizing poor physical layouts and tenant mix rather than shopping centre aesthetics.

Channels of distribution are basic to the marketing strategies of firms, and have been shown to be a key element in the marketing mix. The author here undertakes a comprehensive review of channels literature, primarily to identify and assess the adequacy of the various mainstream conceptual schemes which have emerged. Economic‐based arguments have largely been at the core of channels literature, although these have been partially offset by the concepts of the organisational and behavioural schools. The author concludes that whereas every conceptual approach reviewed has added something to our cumulative knowledge, no single approach has yet reached a point of adequate conceptualisation based on his own basic criteria. As yet channels literature is mainly descriptive, and has virtually no predictive power.

This paper aims to examine the impact of environmental scanning (ES) on competitive advantage (CA) through the mediation of organizational resilience dimensions within manufacturing small and medium-sized enterprises (SMEs) in Egypt.

This study adopts a cross-sectional design to collect data. This study used a self-administered questionnaire to collect data from a sample of 249 Egyptian SMEs. This study employed the Smart partial least square structural equation modeling technique to test the hypotheses.

ES positively affects CA both directly and indirectly through the mediation of organizational resilience dimensions, namely, robustness and agility. However, ES does not affect integrity; therefore, integrity does not mediate the ES–CA relationship. These results indicate that organizational resilience partially mediates the relationship between ES and CA.

The sample size was small, covering only Egyptian manufacturing SMEs. The results may be different in the service sector and other countries. The study was cross-sectional which could not trace the long-term effects of ES and organizational resilience on CA. Therefore, a longitudinal study should be conducted, based on resource availability.

Managers in Egyptian SMEs should scan their environments to build organizational resilience and, in turn, enhance their CA.

To the best of the authors’ knowledge, this research is among the first endeavors to investigate the role of ES in building CA through organizational resilience in the context of Egyptian SMEs.

This paper aims to supply an introduction to the bioinformatics discipline for information professionals, outlining how current information management issues are hampering the effective integration and interoperability of resources.

The approach taken is to outline some of the more challenging issues to illustrate their consequences, such as syntactic and semantic heterogeneity, data storage formats and media, and the existence of inconsistencies in information content in bioinformatics resources. A discussion of these topics indicates how semantic web concepts and technologies, together with e‐science initiatives, can be used to address these problems.

The paper reveals that, if one considers the use of semantic web technologies such as XML and ontologies for the development of information standards that allows integration of different information systems, these systems could then be placed into applications such as web services and GRIDS tailored for biological studies. Such applications would provide automated functionality for database integration, workflow management, inclusion of provenance data, and notification of services.

The value of this paper is that it exemplifies how information professionals can make an impact on the discipline of bioinformatics, which historically has not been addressed by experts with information skills.

The analyses of trends in prosecutions under the Food and Drugs Act, 1955 and the various regulations, which we have prepared every two years or so, covering a three‐month period, have been so much appreciated by readers, both in the administration and the industry itself, that we have prepared a more extended survey, covering the whole of 1966. The survey, as before, takes the form of a month‐by‐month analysis of reports of legal proceedings received by us from all parts of the country, and as formerly records the prosecutions under similar groupings; cases under Section 2, subdivided into those relating to compositional offences, the presence of foreign bodies and those relating to mouldy food: false description cases under Section 6 of the Merchandise Marks Acts; Section 8, the unfit food provision, also subdivided with special categories for foreign bodies and mouldy food; Section 32, milk cases; cases under the Food Hygiene Regulations, 1960, with smoking offences separated; the Milk and Dairies Regulations, consisting almost entirely of prosecutions under Reg. 27, Meat Regulations, Preservative Regulations, Colouring Matter in Food Regulations, etc.

The focus of this paper is the Transformational Model of Rehabilitation. The paper outlines key elements of rehabilitation therapy models before proceeding to describe the Transformational Model and the interpretive case study of Jean Varnier which produced this unique approach therapy to rehabilitation. In particular it is argued that its unique contribution to mental health is in its requirement that the professional engage with his/her own transformational process, which ensures reflexivity and supports the expression of maturity as agency and authenticity in clients.

This paper aims to advance the idea of consequential engagement, positioning it as a necessary complement to the more common practices of supporting procedural or conceptual engagement. More than a theoretical argument, this notion is grounded in examples from the authors' work in enlisting game‐based methodologies and technologies for supporting such engagement.

Through the presentation of two example designs, an elementary statistics curriculum and an undergraduate educational psychology course, the paper attends to the potential of narratively‐rich, multi‐user virtual environments for positioning students to critically engage academic content. In particular, it discusses the importance of designing spaces that afford opportunities to understand and apply disciplinary concepts in making sense of, and potentially transforming, conceptually‐revealing scenarios.

The paper discusses the role of consequential engagement in supporting meaningful procedural and conceptual engagement, and the potential of these designed spaces for positioning learners to develop an appreciation both of the power of the conceptual tools they engage, and of themselves and their peers as people who use these tools.

This paper proposes a framework for design that can be applied to both real and virtual learning environments.

eScience workflows use orchestration for integrating and coordinating distributed and heterogeneous scientific resources, which are increasingly exposed as web services. The rate of growth of scientific data makes eScience workflows data‐intensive, challenging existing workflow solutions. Efficient methods of handling large data in scientific workflows based on web services are needed. The purpse of this paper is to address this issue.

In a previous paper the authors proposed Data‐Flow Delegation (DFD) as a means to optimize orchestrated workflow performance, focusing on SOAP web services. To improve the performance further, they propose pipelined data‐flow delegation (PDFD) for web service‐based eScience workflows in this paper, by leveraging from the domain of parallel programming. Briefly, PDFD allows partitioning of large datasets into independent subsets that can be communicated in a pipelined manner.

The results show that the PDFD improves the execution time of the workflow considerably and is capable of handling much larger data than the non‐pipelined approach.

Execution of a web service‐based workflow hampered by the size of data can be facilitated or improved by using services supporting Pipelined Data‐Flow Delegation.

Contributions of this work include the proposed concept of combining pipelining and Data‐Flow Delegation, an XML Schema supporting the PDFD communication between services, and the practical evaluation of the PDFD approach.

Pusher configured turbo-prop aircraft receive inadequate ram air cooling due to the lack of propeller slipstream, particularly during ground operations. However, flow entrainment can be exploited to a greater extent by placing the oil-cooler duct close to downstream of the propeller at a suitable radial location. But this method has a detrimental effect on the propeller thrust. The purpose of this paper is to discuss the results of numerical simulations carried out to simulate the performance of the propeller with and without oil cooler.

In this paper, three-dimensional (3D) numerical simulations are carried out to simulate the propeller in a rotating domain using an unstructured grid. A computational fluid dynamics solver is put forward to analyze the effect of thrust loss by solving 3D Navier-Stokes equations using a second-order upwind finite-volume scheme. In this study, the impact of thrust loss incurred in the propeller flow field with and without oil cooler duct for three different locations at various rotational speeds is carried out to assess the propeller performance and to identify the optimum position to get a sufficient mass flow rate.

The findings from this study are simulated thrust values of an uninstalled five-bladed propeller of light transport aircraft (LTA) match well with original equipment manufacturer propeller thrust data. The tip speed velocities simulated for different operating conditions are in good agreement with the theoretical calculations. The influence of oil-cooler effect on the propeller flow field is less in low velocity to high-velocity operating condition due to flow transition from laminar to turbulent. The presence of the oil cooler, which influences the thrust loss, is studied at propeller upstream and downstream locations in detail for 30%, 40% and 50% of propeller radius cases.

Simulations with finer and structured hexa grids can be applied to this problem to get closer results and save solver time as future work.

The recommended system is installed in the production standard aircraft of LTA. After installation oil cooler performance is better compared to the previous arrangement.

Research work about pusher aircraft is very limited. The problem addressed in this study is unique which resolves the major issue of pusher aircraft. This work highlights the difficulty involved in LTA engine oil cooling, and solution methodologies are also provided. Numerical simulation with oil-cooler assembly is a new area of research that gave the solution for this oil-cooling issue through various oil-cooler case studies.
