Abstract

Throughout the 1980s and early 1990s the debate surrounding the comparative costs and benefits of town centre and out‐of‐town retail developments for consumers and to the environment has been a heated one. Informed by a largely puritanical view of consumerism, current Government policy tends towards the preservation of the traditional town centre. However, the actual evidence is far from conclusive and there is limited consumer research supporting this stance. Based on an interviewer‐administered survey conducted during 1994 and 1995 to assess shoppers’ opinions in both types of location in Preston, presents an examination of consumer perspectives and examines differences in perceptions and behaviour patterns among town centre and out‐of‐town shoppers.

The purpose of this research is to assess the service quality of central blood bank from blood donors’ perspective.

Abstract

Purpose

The purpose of this research is to assess the service quality of central blood bank from blood donors’ perspective.

Design/methodology/approach

Data were collected by empirical study in a central blood bank. The instrument captured 354 blood donors’ using a SERVQUAL questionnaire. The study looked at perception and expectation levels of blood donors. After that, the gap five scores were determined.

Findings

The paper finds that, for the blood donors, gap (five) scores are all positive implying that the blood donors’ tend to be satisfied.

Practical implications

Based on the results, central blood bank management may consider measures in order to diagnose, analyze, and identify opportunities of improvements of service quality.

Originality/value

This study attempts to explore the relatively less explored area of measuring service quality of a central blood bank from blood donors’ perspectives through implementation of the SERVQUAL model.

Abstract

Purpose

The purpose of this paper is to both determine the effects of the nonlinearity on the wave dynamics and assess the temporal and spatial accuracy of five finite difference methods for the solution of the inviscid generalized regularized long-wave (GRLW) equation subject to initial Gaussian conditions.

Design/methodology/approach

Two implicit second- and fourth-order accurate finite difference methods and three Runge-Kutta procedures are introduced. The methods employ a new dependent variable which contains the wave amplitude and its second-order spatial derivative. Numerical experiments are reported for several temporal and spatial step sizes in order to assess their accuracy and the preservation of the first two invariants of the inviscid GRLW equation as functions of the spatial and temporal orders of accuracy, and thus determine the conditions under which grid-independent results are obtained.

Findings

It has been found that the steepening of the wave increase as the nonlinearity exponent is increased and that the accuracy of the fourth-order Runge-Kutta method is comparable to that of a second-order implicit procedure for time steps smaller than 100th, and that only the fourth-order compact method is almost grid-independent if the time step is on the order of 1,000th and more than 5,000 grid points are used, because of the initial steepening of the initial profile, wave breakup and solitary wave propagation.

Originality/value

This is the first study where an accuracy assessment of wave breakup of the inviscid GRLW equation subject to initial Gaussian conditions is reported.

Abstract

Purpose

The purpose of this paper is to solve an unsteady nonlinear convective‐radiative equation and a nonlinear convective‐radiative‐conduction equation containing two small parameters of ε1 and ε2 by variational homotopy perturbation method.

Design/methodology/approach

The heat transfer equations are described. The variational homotopy perturbation method as a powerful method for solving linear and nonlinear equations is applied to find the solutions of our model equations.

Findings

The solutions of heat transfer equations are calculated in the form of convergent series with easily computable components. Two examples are solved as illustrations, using symbolic computation.

Originality/value

The results show that the suggested method is easy to implement and has high level of accuracy. The method introduces a reliable tool for solving many linear and nonlinear differential equations.

Abstract

Purpose

This paper aims to explore the use of tangible user interfaces for teaching concepts related to internet of things by focusing on two aspects, notably, usability and learning effectiveness.

Design/methodology/approach

To assess the usability of IoTTT, Nielsen’s principles were used due to its relevance and popularity for usability assessment. In the usability questionnaire, four attributes were evaluated, notably, learnability, efficiency, errors and satisfaction. As for evaluating learning effectiveness, learning assessment was conducted through pre-tests and post-tests. Two groups of 20 students participated where the first group attended conventional lectures on IoT, whereas the second group used IoTTT for learning same concepts. In the process, data was collected through the usability questionnaire and tests for usability and learning effectiveness assessment.

Findings

Results revealed a positive score for the usability of the TUI solution with an average rating of 3.9. Although this score demonstrated an acceptable solution, different issues were identified, based on which a set of recommendations have been made in this paper. On the other hand, in the common pre-tests, an average score of 6.40 was obtained as compared to a mean score of 7.33 in the post-tests for all participants. Knowledge gains were significantly higher for students who learnt IoT concepts through the TUI-based system where performance improved by 18 per cent.

Originality/value

The results revealed in this study are expected to help the research community, course designers and tutors comprehend the prospects of using tangible user interfaces to foster teaching and learning of IoT concepts. In addition, educational solution providers could consider commercialisation prospects of this technology to innovate in teaching and learning, while also building-up on limitations identified within this study.
