Abstract
Psychology and neurobiology nowadays provide a large amount of precise information on visual system function. This information can be used in the design of autonomous systems capable of learning and recognising objects and places important for survival in complex unknown (real or virtual) environments. Our work is based on the principles that perception is fundamentally a dynamic process in constant interaction with movement; and that learning can be made simpler if the systems are not required to learn the invariants of their environment (e.g. preservation of neighbour topological relations, or connectivity of the space). The techniques that contribute to devising these adaptive systems in continuous interaction with their environment could significantly influence our approach to programming and the man‐machine interface.

Abstract
Purpose
The purpose of this paper is to present details of a study investigating learning styles differences of Thai students in England compared to local students in England and Thailand. It also discusses key issues in using learning styles in multicultural and international education, given their wide availability online.
Design/methodology/approach
A mixed methods design is used, including a psychometric approach using Vermunt's Inventory of Learning Styles (ILS) with three postgraduate Business student samples – Thai (in England, n=26), European (in England, n=16) and Thai (in Thailand, n=122) and a qualitative approach using focus groups, interviews and open‐ended questionnaires with the Thai (in England, n=43) sample only.
Findings
One‐way independent analysis of variance analyses on ILS scores show that learning styles differ significantly between the three samples on each of the test occasions, particularly in meaning‐directed learning and undirected learning. The qualitative data analysis shows that Thai students in England perceive culturally‐determined differences in teaching and learning behaviour between Thai and English higher education environments that can cause difficulties for them.
Research limitations/implications
The use of mixed methods gives data of greater breadth and depth than a single method; however, the sample sizes are somewhat limited.
Practical implications
Thai students in England require additional support from educators and educational institutions.
Originality/value
This paper provides a valuable insight into the learning styles and needs of Thai students in England, given the paucity of research in this area.

Abstract
Personal Finance has, in our view, been an area of relative neglect in academic circles in the UK compared, say, to the USA. This statement is based on a perusal of course listings and contents from both sides of the Atlantic. That, of course, is not to say that the subject matter is completely ignored as other courses in economics, financial management and accounting often cover topics which would be found in a fully fledged course on personal finance. Additionally, academics and others do write and publish in the UK (witness this current volume) on some of the subject matter, and the newspapers and periodicals offer a wide variety of advice to would‐be savers and borrowers. What is lacking, perhaps, is a systematic framework into which the various activities can be placed.

Abstract
In this account of our long-term ethnographic investigation of the Burning Man Project, we examine the emergence of nomadic spirituality among the citizens of Black Rock City, Nevada. We describe this emergence as a reaction to consumers’ increasing dissatisfaction both with conventional religious denominations and with consumption as an existential ground of meaning. We provide an emic view of the pilgrimage experience at Black Rock City, from the perspective of participants in and organizers of the event. We propose a theory of the comedy of the commons to interpret the surface structure of the moment, and embed our deep structural interpretation of the nomadic spirituality of the phenomenon within the context of new religious movements (NRMs). In so doing, we shed new light on the topic of the sacred and profane in consumer experience.

Abstract
Purpose
Construction organisations are becoming increasingly aware of the impacts of their operations, from both an environmental and, more recently, a social viewpoint. Sustainability standards can enable an organisation to evidence a benchmarked level of performance against a particular issue. To date, research on standards has largely focused on the operational and administrative aspects of their enactment, rather than how they might affect – and be appropriated by – organisational actors. The purpose of this paper is to examine how capacity for learning can affect the success of implementing standards within two construction SMEs.
Design/methodology/approach
Taking an organisational learning and absorptive capacity (ACAP) perspective, this research uses the case study approach and abductive logic to understand what role learning plays with regard to sustainability standard implementation.
Findings
The results reveal that strong communication channels and commitment to training programmes increase the capacity for implementing standards, but that SMEs tend only to approach standards if they see immediate financial benefits stemming from their implementation.
Practical implications
SMEs provide a challenging context for the implementation of sustainability standards unless there are significant external levers and extrinsic motivation for them to be embraced. Care should be taken in incorporating these aspects into the future design of standards that are more aligned with SME needs.
Social implications
Stakeholders should seek to apply pressure to firms to positively influence engagement with sustainability standards.
Originality/value
The role and importance of ACAP is an underdeveloped debate in the certification field. This study is the first that links the process of implementing a standard with the ACAP of an organisation.

Abstract
This chapter examines the acts of burial and exhumation in three contemporary British history plays. For the purposes of this argument, a ‘history play’ may be defined as a piece of writing for the theatre that engages with historical events or settings. Such plays inevitably, at the moment of their staging or revival, take on particular meanings for audiences, since theatre as a live, durational art form encourages spectators to compare the historical events depicted with their present historical moment. The chapter argues that acts of burial and exhumation in contemporary British theatre are intimately tied to notions of land, soil and belonging. These became increasingly pertinent ideas in the UK’s political climate in the years following the 2016 Referendum on membership of the European Union. Of the three case studies, Victoria by David Greig (2000) dates from more than a decade before this vote, whilst Common by D. C. Moore (2017), and Eyam by Matt Hartley (2018) were written and staged in the interim between the Referendum result and the UK’s withdrawal from the EU. All three, however, feature corpses on stage as a means to consider time, temporality, place and history. Each play offers a different interpretation of what it means to play dead and to stay dead.

Abstract
Purpose
The application of dry-type transformers is growing in the market because the technology is non-flammable, safer and environmentally friendly. However, the unit dimensions are normally larger and material costs become higher, as no oil is present for dielectric insulation or cooling. At designing stage, a transformer thermal model used for predicting temperature rise is fundamental and the modelling of cooling system is particularly important. This paper aims to describe a thermal model used to compute dry transformers with different cooling system configurations.
Design/methodology/approach
The paper introduces a fast-calculating thermal and pressure network model for dry-transformer cooling systems, preliminarily verified by analytical methods and advanced CFD simulations, and finally validated with experimental results.
Findings
This paper provides an overview of the network model of dry-transformer cooling system, describing its topology and its main variants including natural or forced ventilation, with or without cooling duct in the core, enclosure with roof and floor ventilation openings and air barriers. Finally, it presents a formulation for the new heat exchanger element.
Originality/value
The network approach presented in this paper allows to model efficiently the cooling system of dry-type transformers. This model is based on physical principles rather than empirical assessments that are valid only for specific transformer technologies. In comparison with CFD simulation approach, the network model runs much faster and the accuracies still fall in acceptable range; therefore, one is able to utilize this method in optimization procedures included in transformer design systems.

Abstract
Purpose
With aims to increase the aerodynamic efficiency of aerodynamic surfaces, study on flow control over these surfaces has gained importance. With the addition of flow control devices such as synthetic jets and vortex generators, the flow characteristics can be modified over the surface and, at the same time, enhance the performance of the body. One such flow control device is the tubercle. Inspired by the humpback whale’s flippers, these leading-edge serrations have improved the aerodynamic efficiency and the lift characteristics of airfoils and wings. This paper aims to discusses in detail the flow physics associated with tubercles and their effect on swept wings.
Design/methodology/approach
This study involves a series of experimental and numerical analyses that have been performed on four different wing configurations, with four different sweep angles corresponding to 0°, 10°, 20° and 30° at a low Reynolds number corresponding to Rec=100,000.
Findings
Results indicate that the effect of tubercles diminishes with an increase in wing sweep. A significant performance enhancement was observed in the stall and post-stall regions. The addition of tubercles led to a smooth post-stall lift characteristic compared to the sudden loss in the lift with regular wings. Among the four different wings under observation, it was found that tubercles were most effective on the 0° configuration (no sweep), showing a 10.8% increment in maximum lift and a 38.5% increase in the average lift generated in the post-stall region. Tubercles were least effective on 30° configuration. Furthermore, with an increase in wing sweep, co-rotating vortices were distinctly observed rather than counter-rotating vortices.
Originality/value
While extensive numerical and experimental studies have been performed on straight wings with tubercles, studies on the tubercle effect on swept wings at low Reynolds number are minimal and mainly experimental in nature. This study uses numerical methods to explore the complex flow physics associated with tubercles and their implementation on swept wings. This study can be used as an introductory study to implement passive flow control devices in the low Reynolds number regime.
