Abstract

The tourism industry in South Africa today faces the dual challenges of finding ways to extend tourism spending into previously marginalised communities and to redress the imbalances in cultural representations of those communities. The legacy of formal racial segregation is extremely difficult to reverse. The study investigated the potential of Edu-tourism to fundamentally change tourism dynamics. This approach targets young, intelligent, ‘new tourists’ who choose different types of visitor experiences and contribute to changing the way South Africans value and use their own cultures. The method used included requiring students to design tourist packages, in consultation with tour guides, visitors and local community members. The outcomes provide stimulation for new research, widely distributed income generation and building bridges between divided communities.

Abstract

Purpose

The paper introduces and illustrates the use of numerical models for the simulation of electromagnetic and thermal processes in an absorbing ceramic layer (susceptor) of a new millimeter-wave (MMW) heat exchanger. The purpose of this study is to better understand interaction between the MMW field and the susceptor, choose the composition of the ceramic material and help design the physical prototype of the device.

Design/methodology/approach

A simplified version of the heat exchanger comprises a rectangular block of an aluminum nitride (AlN) doped with molybdenum (Mo) that is backed by a thin metal plate and irradiated by a plane MMW. The coupled electromagnetic-thermal problem is solved by the finite-difference time-domain (FDTD) technique implemented in QuickWave. The FDTD model is verified by solving the related electromagnetic problem by the finite element simulator COMSOL Multiphysics. The computation of dissipated power and temperature is based on experimental data on temperature-dependent dielectric constant, loss factor, specific heat and thermal conductivity of the AlN:Mo composite. The non-uniformity of patterns of dissipated power and temperature is quantified via standard-deviation-based metrics.

Findings

It is shown that with the power density of the plane wave on the block’s front face of 1.0 W/mm2, at 95 GHz, 10 × 10 × 10-mm blocks with Mo = 0.25 – 4% can be heated up to 1,000 °C for 60-100 s depending on Mo content. The uniformity of the temperature field is exceptionally high – in the course of the heating, temperature is evenly distributed through the entire volume and, in particular, on the back surface of the block. The composite producing the highest level of total dissipated power is found to have Mo concentration of approximately 3%.

Research limitations/implications

In the electromagnetic model, the heating of the AlN:Mo samples is characterized by the volumetric patterns of density of dissipated power for the dielectric constant and the loss factor corresponding to different temperatures of the process. The coupled model is run as an iterative procedure in which electromagnetic and thermal material parameters are upgraded in every cell after each heating time step; the process is then represented by a series of thermal patterns showing time evolution of the temperature field.

Practical implications

Determination of practical dimensions of the MMW heat exchanger and identification of material composition of the susceptor that make operations of the device energy efficient in the required temperature regime require and expensive experimentation. Measurement of heat distribution on the ceramic-metal interface is a practically challenging task. The reported model is meant to be a tool assisting in development of the concept and supporting system design of the new MMW heat exchanger.

Originality/value

While exploitation of a finite element model (e.g. in COMSOL Multiphysics environment) of the scenario in question would require excessive computational resources, the reported FDTD model shows operational capabilities of solving the coupled problem in the temperature range from 20°C to 1,000°C within a few hours on a Windows 10 workstation. The model is open for further development to serve in the ongoing support of the system design aiming to ease the related experimental studies.

Abstract

Cultural criminologists have long been interested in the politics of crime and deviance, whether that be in relation to youth subculture resistance or the social reaction to transgression evident in the media construction of folk devils and moral panics. While contemporary ‘new’ cultural criminology continues to be focused on the situated experience of deviant ‘edgeworkers’, this chapter argues cultural criminology’s concern with the crime-media nexus provides particularly fertile ground for exploring insights provided by activists, academics, professional journalists and citizen journalists around informal interventions on formal criminal justice processes using social media and digital technologies. Drawing on examples from a burgeoning body of crime-media research, the chapter makes a case for ‘cultural criminology activism’, which, like activist criminology, is consciously disengaged from mainstream criminology’s alignment with the neoliberal-carceral state and its reformist agenda.

Abstract

Purpose

Skilled migrants' careers are heterogeneous, with existing theories capturing only some of their diversity and dynamic development over time and circumstance. This paper aims to draw out the multilevel (macro, meso and micro levels) influences impacting skilled migrants' careers by using the lens of the intelligent career framework. Furthermore, structuration theory captures the agency of skilled migrants facing different social structures at and across levels and explains the idiosyncratic nature of skilled migrants' careers.

Design/methodology/approach

Following an abductive approach, this paper examines the career influences for a sample of 41 skilled migrants in three different host countries. Individual career stories were collected through qualitative interviews. Important career influences from these narratives are categorised across the intelligent career competencies (knowing why, how and whom) at the macro, meso and micro levels.

Findings

Findings illustrate the lived reality for skilled migrants of these interrelated multilevel career influences and go some way in elucidating the heterogeneity of skilled migrants' careers and outcomes. The interplay of individual agency in responding to both facilitating and challenging social structures across the multilevels further explains the idiosyncratic nature of skilled migrants' careers and how/whether they achieve satisfying career outcomes. Some potential policy implications and options arising from these findings are suggested.

Originality/value

By considering multilevel themes that influence skilled migrants' career capital, the authors were able to better explain the complex, relational and idiosyncratic shaping of their individual careers. As such, the framework informs and guides individuals, practitioners and organisations seeking to facilitate skilled migrants' careers.

Abstract

Purpose

The quantity and quality of available water resources have been recognized limiting factors in development of most of the arid and semi arid regions. The purpose of this paper is to evaluate the efficiency, for water users' associations (WUA), of irrigation project Samrat Ashok Sagar (Halali) in India, using benchmarking by data envelopment analysis as the performance evaluation tool and to integrate the outcome of the benchmarking process for planning, design and effective management of available water resources.

Design/methodology/approach

To collect information or data required to calculate indicators, there was personal interaction with water users and executive engineers in‐charge of the project, and competent authority for WUA (sub‐engineers), with other technical staff and with establishment staff and the purpose of the study explained. In the analysis, the performance gap was compared within the scheme. The causes of the performance gap and the action required for closing the performance gap were explored. Data envelopment analysis was done for different sets of input output by input‐oriented model through software. The data collected were real time and validated from Samrat Ashok Sagar Irrigation and Drainage Project Authority.

Findings

It was found that the majority of WUAs as per model I to model VI had efficiency below 70 per cent, which is a matter of serious concern. It is evident that considerable variations occur amongst the various WUAs in terms of the operational characteristics reflected by the independent variables.

Originality/value

The paper demonstrates that it is evident that considerable variations occur amongst the various WUAs in terms of the operational characteristics reflected by the independent variables.

Abstract

Purpose

The internet driven information revolution is frequently cited as one of the key drivers (re‐)shaping contemporary consumption. In particular, the internet has been seen as disrupting established conventions in professional services. Popularly, it has been viewed as a liberating medium, a mechanism by which consumers and citizens have been able to challenge the authority of the professional establishment. Yet for consumers, the internet can equally be viewed as generating new uncertainties and challenges in terms of negotiating a new settlement with professionals and reconfiguring the service encounter. The purpose of this paper is to explore experiences of consumers with the use of internet derived information in respect of complex professional services and the impact of such information utilisation on the format of the service encounter.

Design/methodology/approach

Empirical data is generated through interviews with professionals (n=24) and consumer focus groups (n=10/53).

Findings

The paper argues that the multi‐faceted nature of the internet creates informational “spaces” which present both opportunities and threats to consumers in renegotiating the service encounter. Balancing the paradoxes created by these informational spaces is at the core of the challenge confronting contemporary service consumers. Irrespective of the nature of that space, the effect is to create a driver for change, challenging the established practices of both consumer and professional to reshape the service encounter.

Research limitations/implications

Focus group research does not enable a judgement about the prevalence or distribution of behaviours among consumers. Nevertheless, this paper advances understanding of contemporary consumption practices and provides a new perspective on nature of consumer utilisation of information within the consumption process.

Practical implications

It is inevitable that professionals and service organisations will be required to respond to a complex and rapidly evolving set of consumer behaviours and rethink approaches to the delivery of professional services.

Originality/value

The paper addresses an emergent phenomenon and provides unique insights into the changing dynamics of consumption practices in the contemporary knowledge economy.

Abstract

Purpose

Most studies pertaining to social tagging focus on one platform or platform type, thus limiting the scope of their findings. The purpose of this paper is to explore social tagging practices across four platforms in relation to cultural products associated with the book Casino Royale, by Ian Fleming.

Design/methodology/approach

A layered and nested case study approach was used to analyse data from four online platforms: Goodreads, Last.fm, WordPress, and public library social discovery platforms. The top-level case study focuses on the book Casino Royale, by Ian Fleming and its derivative products. The analysis of tagging practices in each of the four online platforms is nested within the top-level case study. Casino Royale was conceptualized as a cultural product (the book), its derived products (e.g. movies, theme songs), as well as a keyword in blogs. A qualitative, inductive, and context-specific approach was chosen to identify commonalities in tagging practices across platforms whilst taking into account the uniqueness of each platform.

Findings

The four platforms comprise different communities of users, each platform with its own cultural norms and tagging practices. Traditional access points in the library catalogues focused on the subject, location, and fictitious characters of the book. User-generated content across the four platforms emphasized historical events and periods related to the book, and highlighted more subjective access points, such as recommendations, tone, mood, reaction, and reading experience. Revealing shifts occur in the tags between the original book and its cultural derivatives: Goodreads and library catalogues focus almost exclusively on the book, while Last.fm and WordPress make in addition cross-references to a wider range of different cultural products, including books, movies, and music. The analyses also yield apparent similarities in certain platforms, such as recurring terms, phrasing and composite or multifaceted tags, as well as a strong presence of genre-related terms for the book and music.

Originality/value

The layered and nested case study approach presents a more comprehensive theoretical viewpoint and methodological framework by which to explore the study of user-generated metadata pertaining to a range of related cultural products across a variety of online platforms.

Abstract

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract

The principal organisational issues relating to the creation, validation and maintenance of the University of Exeter's Web site are discussed from the viewpoint of the University Library. Important issues include the effective allocation of responsibility, the timely formation of working groups, and the fostering of a spirit of cooperation amongst all departments and services responsible for providing or authorising information. Given the Web's popularity amongst users and the wealth of opportunities it provides for the dissemination of information, the commitment to its development already shown by library staff must continue.
