Abstract

Purpose

To provide an analysis of transient heat conduction, which is solved using different iterative solvers for graduate and postgraduate students (researchers) which can help them develop their own research.

Design/methodology/approach

Three‐dimensional transient heat conduction in homogeneous materials using different time‐stepping methods such as finite difference (Θ explicit, implicit and Crank‐Nicolson) and finite element (weighted residual and least squared) methods. Iterative solvers used in the paper are conjugate gradient (CG), preconditioned gradient, least square CG, conjugate gradient squared (CGS), preconditioned CGS, bi‐conjugate gradient (BCG), preconditioned BCG, bi‐conjugate gradient stabilized (BCGSTAB), reconditioned BCGSTAB and Gaussian elimination with incomplete Cholesky factorization.

Findings

Provides information on which time‐stepping method is the most accurate, which solver is the fastest to solve a symmetric and positive system of linear matrix equations of all those considered.

Practical implications

Fortran 90 code given as an abstract can be very useful for graduate and postgraduate students to develop their own code.

Originality/value

This paper offers practical help to an individual starting his/her research in the finite element technique and numerical methods.

Abstract

Purpose

To provide an analysis of turbulent flow in plane diffusers for graduate and postgraduate students (researchers) which can help them to understand turbulent flows and turbulence modelling.

Design/methodology/approach

Steady, incompressible, turbulent flow in two‐dimensional plane diffusers, where Reynolds averaged Navier‐Stokes (RANS) equations were simplified using the theory of turbulent boundary layers in integral form adjusted for the internal flow. To close the RANS equations, the mixing length model proposed by Michel et al., which was previously used for the calculation of turbulent flow in a straight channel with a uniform cross section, is applied for the calculation of the turbulent flow in plane diffusers. Also, in this paper, the velocity profile is approximated in every cross‐section of the diffuser by a six‐order polynomial, whose coefficients depend upon the three form parameters. Using this transformation, the system of governing equations was reduced to the three ordinary differential equations which were solved numerically.

Findings

A comparison between results obtained (velocity profiles) and experimental data obtained using HWA and LDA shows very good agreement. The method of integral equations of boundary layer is a relatively old method and tends to be forgotten since more advanced methods have been introduced. However, the results obtained using this method for the calculation of turbulent flow in a plane diffuser show a very good agreement with experimental data. Therefore, in engineering applications when simplicity and low‐cpu times are required, the integral method can still be applied successfully.

Originality/value

This paper offers practical help to an individual starting his/her research in the computational fluid dynamics (turbulence modelling).

Abstract

This chapter aims to (1) examine the effect of full-time employees’ STARA awareness on innovative work behavioural intentions in US casual dining restaurants; (2) investigate the mediating roles of employees’ challenge–hindrance appraisals of STARA awareness on the relationship between their STARA awareness and innovative work behavioural intentions; (3) compare the group differences between management employees and non-management employees; and (4) provide recommendations for the casual dining restaurants.

This chapter employed an online survey to collect data from 609 full-time employees in US casual dining restaurants, including 306 management employees and 303 non-management employees. Partial least squares–structural equation modelling was applied for data analysis. The results reveal that the high levels of employees’ STARA awareness raise innovative work behavioural intentions through the mediations of challenge appraisal of STARA awareness.

The proposed conceptual framework and empirical findings in this chapter enrich the literature of cognitive appraisal theory, transactional model and stress, two-dimensional stressor framework, and person-environment fit theory. Employees’ challenge appraisal of STARA awareness makes the job insecurity stressor to drive innovative work behavioural intentions. As STARA adoption deepens in casual dining restaurants, managers need to be aware of full-time employees’ stress and psychological responses towards STARA adoption. Restaurants are suggested to provide employees with adequate resources and support to help employees’ professional competency growth. The capable employees will appraise the job insecurity stressor induced by STARA adoption as an opportunity and be motivated to perform innovatively in the workplace. The casual dining restaurants may enjoy a competitive advantage in the market through value-added innovative activities.

Abstract

Purpose

This research explores how protest events can change and develop over time, through an analysis of stakeholder perceptions of the EXIT festival in Serbia. In doing this, it builds on previous research into protest events from a critical events studies perspective and has implications for the management and understanding of events linked to social movements.

Design/methodology/approach

This research took a neo-institutionalist perspective and is based on 18 stakeholder interviews, which were analysed using reflexive thematic analysis. Purposive sampling in the highly-networked city of Novi Sad, Serbia, allowed for the inclusion of diverse participants from politics, NGOs, media and the festival itself.

Findings

The findings reveal that the EXIT festival has departed significantly from its original protest roots. Although it is now perceived as part of the dominant political culture in Serbia, it still has the potential to campaign on issues of relevance to the region, which is unrealised. This research demonstrates that the neo-institutionalist perspective can offer fresh insights for research into protest events. Taking this perspective suggests practical implications for the managers of events with protest roots and for social movements seeking to use protestival-style methods to achieve social change.

Originality/value

This paper provides a new theoretical perspective on protest events and proposes a new model that can be used in future research into protest events that persist over time. It also suggests implications for the management and development of protest events within social movements.

Abstract

Some authors have alerted on the state of crisis generated by Covid-19 in the tourism industry worldwide. The restrictive measures disposed by governments generated not only an unparalleled economic crisis but also serious social maladies in society and education (i.e., higher dropout rates and low academic grades). Needless to say that the tourism education was in crisis much time earlier than the Covid-19 pandemic. Echoing Sigala and Ratten, the authors hold the pungent thesis that Covid-19 introduced a new opportunity to reform the epistemology and the basis of the tourism education curricula. Centerd on the role played by pleasure and joy, which is boosted by the digital technologies, this chapter synthesizes the findings of PANCOE, a successful experiment conducted by the University of Palermo, Argentina, to reduce the dropout rates while improving students’ academic performance. The experiment was drawn and applied in the years before and after the pandemic. Results show how pleasure plays a vital role giving students better opportunities in contexts of fear and deprivation.

Abstract

Purpose

Few studies to date have explored factors contributing to the dining experience from a visitor’s perspective. The purpose of this study is to investigate whether different restaurant attributes are critical in evaluating the restaurant experience in online reviews for visitors (non-local) and local guests.

Design/methodology/approach

In all, 100,831 online restaurant reviews retrieved from TripAdvisor are analyzed by using domain-specific aspect-based sentiment detection. The influence of different restaurant features on the overall evaluation of visitors and locals is determined and the most critical factors are identified by the frequency of their online discussion.

Findings

There are significant differences between locals and visitors regarding the impact of busyness, payment options, atmosphere and location on the overall star rating. Furthermore, the valence of the factors drinks, facilities, food, busyness and menu found in the reviews also differs significantly between the two types of guests.

Practical implications

The findings of this study help restaurant managers to better understand the different customer needs. Based on the results, they can better decide which restaurant aspects should receive the most attention to ensure that customers are satisfied.

Originality/value

Research on online reviews has largely neglected the role of different visitation motives. This study assumes that the reviews of local and non-local restaurant visitors are based on different factors and separates them to gain a more fine-grained and realistic picture of the relevant factors for each particular group.

Abstract

Purpose

This study aims to critically evaluate the factual triple bottom line (TBL) sustainability performance of commercial foodservices as featured in peer-reviewed academic publications.

Design/methodology/approach

The commercial foodservices’ sustainability performance-related articles were collected for a systematic review. An inductive thematic analysis was applied to the eligible articles.

Findings

The contribution of the commercial foodservice sector to the TBL sustainability is highlighted through eight themes: food waste management; food safety and hygiene; food allergy management; provision of healthy meals; local food use; employment of the disadvantaged; well-being of (non)managerial personnel; and noise level management.

Originality/value

The critical evaluation of the actual TBL sustainability measures adopted by commercial foodservice providers highlights the feasibility of the measures, thus calling for their broader industry uptake. Research gaps and issues for future investigations are accentuated for scholars to support the industry in its progress towards the goals of the TBL sustainability.

Abstract

Purpose

Dark tourism is a topic of increasing interest, but it is poorly understood when considering its significance for mainstream and commercial tourism. The purpose of this paper is to investigate the significance of dark tourism in the top ten most visited European tourist cities and propose a dark tourism index for Europe’s tourism cities.

Design/methodology/approach

Data were collected from the websites of the cities’ Destination Management Organisations (DMOs) using a content analysis methodology, based on keywords related to dark tourism taken from the research literature in this area. Descriptive statistics were produced and the variance between the frequencies of keywords related to each city was analysed for statistical significance. These results were then used to construct a darkness ranking of the cities.

Findings

There are significant differences in the extent to which dark tourism products and services are promoted by the DMOs of Europe’s top ten most visited European cities. The ranking of cities by darkness does not correspond to the ranking by visitor numbers, and further qualitative analysis suggests that, that the ranking is also independent of the actual presence of dark sites within the destination. This implies that European city DMOs are engaging with the emerging dark tourism market with to varying degrees.

Research limitations/implications

The purposive sample of ten cities can be extended in future research to increase the validity of the findings of this paper. A further limitation is the selection of keywords for content analysis, which have been developed following the literature review contained below. Future research could develop an extended list of keywords using a systematic review process.

Practical implications

This paper shows that it is possible to create a ranking of tourist cities in terms of their darkness, and that this methodology could be extended to a much larger sample size. This links dark tourism research to the urban tourism literature and also offers possibilities for creating a global ranking that could be used by destinations to judge their success in engaging with the dark tourism market, as well as by tour operators seeking to develop products for the same market.

Social implications

This paper will offer DMO’s and others the opportunity to hone their tourism products more effectively in a way which offers a better understanding of tourism, and therefore provides for better management of its issues.

Originality/value

Dark tourism is a growing niche area of study, and this paper seeks to provide a framework to better understand supply-side aspects of it.
