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.

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.

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.

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

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

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.

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.

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.

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

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.

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.

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.

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.

Drones have become an important element within hospitality and tourism. The purpose of this study is to identify the corpus of knowledge and create a research agenda that establishes appropriate guidelines for future study of drone application in hospitality and tourism.

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.

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.

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.

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.

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.

The academic background of tourism marketing dates back to the 1960s. There had been a slight increase in its capacity until the early 1990s. However, since then, it has boomed, reaching thousands of scientific journal articles and tens of scientific books published only in English each year. Therefore, this study aims to present how tourism marketing has progressed academically within the past 60 years over four waves and how this progress may move forward as the next wave.

A bibliometric analysis grounds this study, which characterizes the past and present of tourism marketing research and anticipates the future. Content analysis, such as word clouds and social network analysis, was adopted to identify topic clusters and their connections. A total of 9,239 articles published between 1969 and 2024 were extracted from Scopus. Software packages such as VOSviewer were used to determine connections within topics.

The authors have assessed the findings broadly. Four waves were from the late 1960s to the first quarter of 2000. In spite of the limited size of papers at the early stage, the last wave saw a boom and a diversified number and category of subjects studied. In each wave, new subjects were added to broaden the picture.

The discussion of findings is based only on those scientific papers published in English since 1969 but excludes the whole list of textbooks. Subsequent research should also consider all papers and textbooks released in different languages to have the broadest picture assessment worldwide.

The study conveys various suggestions for industry practitioners and policymakers to focus on carefully assessing trends in marketing tourism services and how these may be shaped shortly. This may help practitioners and policymakers redesign their services and marketing strategies in light of future developments.

This study continues a recent study published by Kozak (2023) that has been elaborated, particularly from the industry perspective. The current study examines the academic profile of all subjects investigated in the case of tourism marketing, but mainly in an academic sense. Accordingly, this paper outlines the facts and trends researchers may follow throughout the research frame published in the past six decades.

旅游营销的学术背景可以追溯到20世纪60年代。在20世纪90年代初之前, 旅游营销的研究能力有所提升, 但增幅有限。然而, 自那时起, 旅游营销领域迅速发展, 每年仅用英文发表的期刊文章已达到数千篇, 出版的书籍也达到了数十本。因此, 本研究旨在展示过去60年内旅游营销研究在学术上的发展历程, 分为四个浪潮, 并探讨未来可能出现的下一个发展浪潮。

本研究以文献计量分析为基础, 描述了旅游营销研究的过去和现在, 并预测了未来的发展。采用内容分析方法, 如词云和社交网络分析, 确定了主题集群及其相互联系。从Scopus数据库中提取了1969年至2024年间发表的9,239篇文章, 并使用VOSviewer等软件包确定了主题之间的联系。

我们对研究结果进行了广泛的评估。从20世纪60年代末到2000年的第一季度, 共出现了四个浪潮。尽管早期阶段的论文数量有限, 但在最后一个浪潮中, 研究主题的数量和类别均呈现出爆炸式增长。在每个浪潮中, 均有新的研究主题被引入, 使得研究广度得以拓宽。

本研究的讨论结果仅基于自1969年以来用英文发表的科学论文, 不包括书籍。后续研究应考虑不同语言发布的所有论文和书籍, 以获得全球范围内最广泛的评估图景。

对行业从业者和政策制定者的建议集中在审慎评估旅游服务营销趋势及其未来可能的变化上。这可能有助于从业者和政策制定者在未来发展背景下重新设计其服务和营销策略。

本研究延续了Kozak（2023）最近发表的以行业视角为主的研究, 从学术角度全面考察了旅游营销领域内所有被研究主题的学术轮廓。具体而言, 本论文概述了过去六十年间已发表研究框架中的事实和趋势, 为研究人员提供可遵循的指导。

Los antecedentes académicos del marketing turístico se remontan a la década de 1960. Hasta principios de la década de 1990 se produjo un ligero aumento de su capacidad. Sin embargo, desde entonces ha experimentado un gran auge, alcanzando miles de artículos de revistas y decenas de libros publicados solo en inglés cada año. Por lo tanto, este estudio pretende presentar cómo ha progresado académicamente el marketing turístico en los últimos 60 años, a lo largo de cuatro oleadas, y cómo este progreso puede avanzar como la siguiente oleada en el futuro.

Un análisis bibliométrico fundamenta este estudio, en el que se caracteriza el pasado y el presente de la investigación en marketing turístico y se anticipa el futuro. Para identificar los grupos temáticos y sus conexiones se adoptaron análisis de contenido, como nubes de palabras y análisis de redes sociales. De Scopus se extrajeron nueve mil doscientos treinta y nueve artículos publicados entre 1969 y 2024. Se utilizaron paquetes de software, como VOSviewer, para determinar las conexiones dentro de los temas.

Hemos evaluado los resultados a grandes rasgos. Hubo cuatro oleadas, desde finales de los años sesenta hasta el primer trimestre de 2000. A pesar del limitado número de trabajos de las primeras oleadas, en la última se produjo un auge y una diversificación del número y la categoría de los temas estudiados. En cada oleada se añadieron nuevos temas para ampliar el panorama.

El análisis de los resultados se basa únicamente en los artículos científicos publicados en inglés desde 1969, pero excluye toda la lista de libros de texto. En futuras investigaciones deberían incluirse todos los artículos y libros de texto publicados en otros idiomas para ofrecer un panorama lo más amplio posible a nivel mundial.

Las recomendaciones para los profesionales del sector y los responsables políticos se centran en evaluar con detenimiento las tendencias en la comercialización de los servicios turísticos y en cómo pueden evolucionar en un futuro próximo. Esto puede ayudar a los profesionales y a los responsables políticos a rediseñar sus servicios y estrategias de marketing teniendo en cuenta la evolución futura.

Este estudio se basa en uno anterior, publicado recientemente por Kozak (2023), que se desarrolló específicamente desde la perspectiva de la industria. El presente estudio examina el perfil académico de todos los sujetos estudiados en el caso del marketing turístico, pero principalmente desde una perspectiva académica. En consecuencia, en este trabajo se esbozan los hechos y tendencias que los investigadores pueden seguir a lo largo del marco de investigación publicado en las últimas seis décadas.

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

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

This exploratory research opens a new avenue of tourism destination enquiry for Dhofar Governorate, Oman. It examines the relationship between the food tourism landscape in the country’s southernmost region and the Government’s stated economic development goals. Tourism is a new industry here and in need of sustainable development. The purpose of this paper is to identify how the natural and human resources of the region may be harnessed to expand food tourism pathways and achieve sustainable economic development e.g. maximising stakeholder benefits.

The literature review highlights many new developments in food tourism for this baseline study. Qualitative and quantitative (i.e. mixed) methods are used including a case study, a pilot survey of key Government stakeholders in Oman’s Ministry of Tourism, food factory tours and interviews with their executives in Dhofar, direct and participant observation at food establishments and events, visits to popular roadside and market food stalls in Salalah and tourism trend analysis.

Some recent trends in food tourism elsewhere may be adapted in Salalah and spark interest in the food culture and heritage of Dhofar. This, in turn, may bring multiple benefits to the destination’s stakeholders. The governorate’s environment yields a rich variety of agricultural and other food products that may be used to provide new forms of food tourism and increase the region’s appeal to tourists beyond the Khareef season. Further possible benefits include safeguarding local food knowledge, production, culture and heritage, developing SMEs, creating new jobs and increasing visitor stay and spend.

The study is conducted solely in English, whereas Arabic is the mother tongue in Oman. Dhofar is the country’s largest governorate occupying a vast area, not all of which is covered by the study. More data are needed to inform tourism development, policymaking and planning in Dhofar.

Improving tourism’s sustainability profile, creating successful food tourism products and services and achieving Dhofar’s economic development goals require concerted effort. All are in the best interest of the tourism stakeholders concerned.

This paper provides a foundation for future research on this topic. It highlights the importance of placing food tourism development on a sustainable footing to protect and preserve Dhofar’s unique food culture, heritage, traditions and environment, extend the main tourism season and maximise benefits to stakeholders.

Recent trends in food tourism are investigated to gauge their applicability in this dynamic region of Oman. Ideas are presented demonstrating possible food tourism pathways to sustainable economic development that benefit a wide range of stakeholders e.g. food tours, food factory tours and shops, food festivals and cookery-school holidays and/or classes.

Little is known about how tourists’ eating habits change between everyday life and holidays. This study aims to identify market segments based on changes in food consumption and experiences of a sun-and-sea destination’s local food. The authors evaluate to what extent tourists consume local food and assess the contribution of local food experiences to the tourists’ overall experience.

The target population was all tourists visiting the Algarve in the Summer 2018 and included both domestic and international sun-and-sea tourists. A sample of 378 valid questionnaires was collected. Data analysis included descriptive analysis, statistical tests and cluster analysis.

Cluster analysis identified three segments: non-foodies, selective foodies and local gastronomy foodies. Results indicate that tourists change their eating habits during holidays, eating significantly more seafood and fish and less legumes, meat, fast food and cereals and their derivatives. International and domestic sun-and-sea tourists reported that eating local food contributes significantly to their overall tourism experience.

Sun-and-sea destinations should promote the offer of local dishes, especially those that include locally produced fish and seafood, to improve the tourist experience, differentiate the destination and increase sustainability.

The authors address three identified research gaps: a posteriori segmentation based on tourists’ food consumption behaviour; measurement of changes in eating practices between home and in a sun-and-sea destination; and assessment of the role of food experiences to overall tourism experience of tourists visiting a sun-and-sea destination.
