Abstract
In adopting and developing the key elements of agility, there is a requirement for enterprises to overcome the philosophical challenges of a shift from mass/lean production to the customisation environment of agile manufacturing. There is a substantial body of knowledge supporting the use of alternative costing systems for operations and production management and particularly mass/lean production, yet none deal with the emerging philosophy of agility. This paper examines the operational cost environment of organisations seeking to attain agility. The paper considers and defines the inter‐ and intra‐enterprise activities required to support the provision of total solution systems for customers. The paper evaluates the requirements at a strategic and operational level for costing in an agile environment. The operational issues for agile costing systems are explored and discussed through an implementation case study.

Abstract
Purpose
The purpose of this paper is to examine the effect of the Helping Interdisciplinary Vocabulary Engineering (HIVE) system on the inter-indexer consistency of information professionals when assigning keywords to a scientific abstract. This study examined first, the inter-indexer consistency of potential HIVE users; second, the impact HIVE had on consistency; and third, challenges associated with using HIVE.
Design/methodology/approach
A within-subjects quasi-experimental research design was used for this study. Data were collected using a task-scenario based questionnaire. Analysis was performed on consistency results using Hooper's and Rolling's inter-indexer consistency measures. A series of t-tests was used to judge the significance between consistency measure results.
Findings
Results suggest that HIVE improves inter-indexing consistency. Working with HIVE increased consistency rates by 22 percent (Rolling's) and 25 percent (Hooper's) when selecting relevant terms from all vocabularies. A statistically significant difference exists between the assignment of free-text keywords and machine-aided keywords. Issues with homographs, disambiguation, vocabulary choice, and document structure were all identified as potential challenges.
Research limitations/implications
Research limitations for this study can be found in the small number of vocabularies used for the study. Future research will include implementing HIVE into the Dryad Repository and studying its application in a repository system.
Originality/value
This paper showcases several features used in HIVE system. By using traditional consistency measures to evaluate a semantic web technology, this paper emphasizes the link between traditional indexing and next generation machine-aided indexing (MAI) tools.

Abstract
The value which can be placed upon the rights of property in a name of a commodity, a food or drink, perhaps famous all over the world, which has come down to us through the centuries, is incalculable. Most of such foods and drinks have a regional association, and are prepared according to methods, often secret, handed down from one generation to another and from locally grown and produced materials. Nowhere are such traditions so well established as in cheese‐making and the wine industry. The names do not signify merely a method of manufacture, since this can be simulated almost anywhere, nor even the raw materials, but differences in climate, the soil and its treatment, its produce, harvesting, even in the contaminants of environment. Rochfort cheese, for example, is made from ewe's milk, but most important, with mould growths found only in the caves of that part of France where it is stored.

Abstract
Purpose
The present book chapter deals with the problem of dark tourism as well as the resilience forms of consumption in post-disaster context.
Design/Methodology/Approach
The turn of the century characterised a radical change in the forms of tourism consumption. New forms of tourism as dark or thana tourism have captivated the attention of scholars and journalists. This book chapter centres efforts in dillucidating what are the key factors that determine the formation of a dark site. The text is inspired in my own ethnographies in Cromañon, Argentina and the Ground Zero, US.
Findings
As Phillip Stone puts it, not all dark shrines or sites welcome tourists. While some sites are reluctant to mass tourism, others are mainly organised around the figure of the tourist. La Republica de Cromañón is a night club where in a fire died 194 young. The site is today refurbished as a sanctuary to remind the victims. At a closer look, there is a tension between stakeholders at the time of promoting dark tourism in Cromañón. In the opposite the ground zero is fully designed to be visited by thousands tourists.
Originality/Value
The originality of this research consists in the contraposition of two study cases which answer the question to what extent dark tourism is desired by locals. The findings lay the foundations towards the specialised literature in dark tourism studies. We discuss critically the nature of thanatopsis.

Abstract
This paper compares the effectiveness of in‐house developed computer‐based learning (CBL) materials with face‐to‐face teaching. Two groups of higher education students were randomly assigned to complete tutorial work in one highly structured topic of introductory accounting using either CBL materials (treatment group) or face‐to‐face teaching (control group). The effectiveness of both approaches was measured according to the students’ performance in a class test, in relation to their prior accounting knowledge and gender. The results showed that the students with no prior accounting knowledge who completed the CBL materials achieved a significantly higher test mark than the face‐to‐face teaching group. However, there was no significant difference in the marks of the students with prior accounting knowledge, and there was no difference on the basis of gender. The results of this South African study correspond to results in existing literature in other countries, and contribute to the overall knowledge of the effectiveness of CBL materials with respect to prior accounting knowledge and gender.

Abstract
Children experience toxic stress if there is pronounced activation of their stress-response systems, in situations in which they do not have stable caregiving. Due to their exposure to multiple poverty-related risks, African American children may be more susceptible to exposure to toxic stress. Toxic stress affects young children’s brain and neurophysiologic functioning, which leads to a wide range of deleterious health, developmental, and mental health outcomes. Given the benefits of early care and education (ECE) for African American young children, ECE may represent a compensating experience for this group of children, and promote their positive development.

Abstract
Purpose
This paper aims to present experimental experience of heavy fuelling of a spark ignition crankcase scavenged two-stroke cycle unmanned aerial vehicle (UAV) engine, particularly focusing on the effects of compression ratio variation, and to cross-correlate with the results of fluid dynamic modelling of the engine and fuels used.
Design/methodology/approach
One-dimensional modelling of the engine has been conducted using WAVE software supported by experimental dynamometer testing of a spark ignition UAV engine to construct a validated computational model using gasoline and kerosene JET A-1 fuels.
Findings
The investigation into the effects of compression ratio variation via fluid dynamic simulation and experimental testing has allowed an assessment of the approach for improving heavy fuel operation of UAV engines using auxiliary transfer port fuel injection. The power level achieved with reduced compression ratio heavy fuel operation is equal to 15.35 kW at 6,500 revolutions per minute compared to 16.27 kW from the standard gasoline engine or a reduction of 5.7%.
Practical implications
The studied engine is specifically designed for UAV applications. The validation of the computational models to explore the effects of compression ratio and heavy fuel injection on the solution and cost is supported by experimental tests.
Originality/value
The application of auxiliary port fuel injection of heavy fuel and associated compression ratio optimisation offers an alternative approach to achieve the safety and logistical challenges of the single fuel policy for UAVs. The application of WAVE to simulate crankcase scavenged two-stroke cycle engines has been applied in very few cases. This study shows further exploratory work in that context.

Abstract
Over the past 50 years, dark tourism has seen exponential growth in terms of both physical and digital contexts. Dark tourism is primarily a concentration around documented accounts of physical violence, and theorizations centered on dark tourism studies have generally fallen within either behavioral or interpretivist perspectives. Such perspectives are indicative of the continually evolving nature of dark tourism and its receptiveness to new definitions, conceptual frameworks, and theorizations. Taking this into consideration, this chapter seeks to develop and broaden the notion of “dark tourism” within the era of late capitalism by presenting fresh theoretical perspectives stemming from critical criminological frameworks. Specifically, in drawing upon critical notions of violence and the emerging deviant leisure framework, this chapter will aim to instigate fresh academic enquiry into the nature of dark tourism, expand its theoretical underpinnings, and subsequently provide a means in which to examine how banal forms of tourism play an integral part in the proliferation of some of the most serious harms that populate the contemporary neoliberal landscape.
