Abstract

Purpose

This study aims to focus on the development of a high-order discontinuous Galerkin method for the solution of unsteady, incompressible, multiphase flows with level set interface formulation.

Design/methodology/approach

Nodal discontinuous Galerkin discretization is used for incompressible Navier–Stokes, level set advection and reinitialization equations on adaptive unstructured elements. Implicit systems arising from the semi-explicit time discretization of the flow equations are solved with a p-multigrid preconditioned conjugate gradient method, which minimizes the memory requirements and increases overall run-time performance. Computations are localized mostly near the interface location to reduce computational cost without sacrificing the accuracy.

Findings

The proposed method allows to capture interface topology accurately in simulating wide range of flow regimes with high density/viscosity ratios and offers good mass conservation even in relatively coarse grids, while keeping the simplicity of the level set interface modeling. Efficiency, local high-order accuracy and mass conservation of the method are confirmed through distinct numerical test cases of sloshing, dam break and Rayleigh–Taylor instability.

Originality/value

A fully discontinuous Galerkin, high-order, adaptive method on unstructured grids is introduced where flow and interface equations are solved in discontinuous space.

This study aims to critically review competitive intelligence (CI) research and offer suggestions for future research in the hospitality and tourism (HT) field.

Abstract

Purpose

This study aims to critically review competitive intelligence (CI) research and offer suggestions for future research in the hospitality and tourism (HT) field.

Design/methodology/approach

The study reviews and synthetizes current CI research in the HT field.

Findings

The study findings suggest that CI research in HT is at an embryonic level, as researchers have not used the same terminology on what CI is, how CI is implemented and what should be included in the CI framework. Hence, researchers should address the link between operation and CI practices. Also, new studies discussing business espionage and ethics in CI practices are needed because the related studies are rare.

Practical implications

The study offers specific theoretical and practical implications for CI research.

Originality/value

This study provides a perspective on future developments of CI research in the HT field.

Abstract

Purpose

The purpose of this paper is to investigate the intellectual structure of coopetition through utilizing a citation and co-citation analysis of scholarly articles focusing on coopetition.

Design/methodology/approach

The authors conducted bibliometric analyses of citation and co-citation analysis. The units of analysis were original research articles and research notes retrieved from journals indexed by well-known databases. Keywords used in the search were “co-opet, co-opet, coopetition, coopetition, simultaneous cooperation and competition, simultaneously cooperate and compete, coexistence of cooperation and competition, coexistence of cooperation and competition, cooperate and compete simultaneously, coopetitive relationships, coopetitive relationships, coopetitive networks, horizontal alliances, cooperate with competitors, cooperation with competitors, cooperative relationships with competitors, cooperative competition and competitive cooperation.” Regarding the time period for publication of the sample articles, the authors did not place any restrictions.

Findings

The research findings provide evidence that coopetition demonstrates multidisciplinary and interdisciplinary characteristics. Subfields of the coopetition field were identified based on the components of coopetition, which are relation, process and strategy. The component dealing with relationship management and innovation as strategy become prominent. Although coopetition literature has emerged as a relation view of strategy, it is still fragmented and diverse. Additionally, the robust subfields generated from the analysis were super-positioned with low degrees.

Originality/value

This is one of the few studies offering a critical review of coopetition research via quantitative research approach.

Abstract

Purpose

The main purpose of this study is to offer a critical review of studies of scientific progress of strategic management (SM) research in the hospitality and tourism field (H&T).

Design/methodology/approach

This study was conducted through a critical literature review based on three dimensions: intellectual, conceptual and social structures of SM research.

Findings

The boundaries of SM under the three dimensions (intellectual, conceptual and social structure) are addressed. Based on these three components, SM in hospitality and tourism realm shows a discursive structure. There are few studies assessing the evolution of SM research in the H&T industry. However, all of these studies are review papers that explored the boundaries of SM research in H&T by using limited keywords to find SM papers, and generally considered papers which are published in a few leading H&T journals.

Research limitations/implications

This study focused on only H&T journals to elaborate the boundaries of SM in H&T. The findings of this study can help researchers (re)design research agendas to contribute to both mainstream and H&T industry SM literature and to enhance the essential elements of theory development in SM research related to H&T industry.

Originality/value

This is one of the first studies assessing the development of SM research related to hospitality and tourism by considering the boundaries of SM in three issues: intellectual, conceptual and social structure.

Abstract

Purpose

This study aims to propose a holistic model to rank and evaluate researchers’ performance. This holistic model is developed by focusing on brand equity, which includes three components of perceived quality, brand image and brand loyalty.

Design/methodology/approach

To show how the model works, two pseudo cases are presented.

Findings

This model encourages researchers to conduct more interdisciplinary research and collaborate with researchers from diverse backgrounds. Because the model includes publication attributes identified by researchers in the publication processes, it allows researchers to strengthen their brand equity score or performance.

Practical implications

The model is applicable not only to the fields of hospitality and tourism but also to other disciplines.

Originality/value

As one of the first studies in the field, this research introduces a holistic model to rank and evaluate researchers’ performance.

Abstract

Purpose

In Turkey, dependence on foreign countries for energy is a problem which upsets all economic balances. Turkey’s biggest fossil energy source is lignite coal. Therefore, energy conversion of lignite in thermal plants, causing minimum environmental effect is extremely important. The basic problem in terms of the combustion technology is to improve the combustion technology that can burn the low-qualified fuels that do not have standard fuel features (lignite, peat, schist). The most suitable technology today for the efficient and clean combustion of nonstandard low-qualified fuels is the combustion at fluidized-bed technology. In this study, CO2 emission that occurs during the combustion of Orhaneli coal that is one of our native low-qualified lignite, has been investigated according to the experimental study.

Design/methodology/approach

For this combustion experiment, laboratory-scaled circulating fluidized-bed (CFB) process that exists at TÜBITAK-MAM Energy Institute which has been designed and used before has been used. The effect of excess-air coefficient, combustion type and bed temperature to the greenhouse gas formation and CO2 emission has been investigated experimentally. In terms of flue gas emissions, it has been detected that the decrease of the amount of CO2 that has occurred has no positive effects on combustion efficiency, water vapor, SO2, NOx, CO and other gases which occur during deficient combustion must be thought as a whole and each reaction affects each other similar to complex reactions.

Findings

As a consequence of measuring CO2 emissions over 10 minute periods, CO2 emissions are 12.43 percent average, CO2 decreases at different air coefficient values; Often form undesirable side reactions such as CO, NOx with back and forth reactions.

Originality/value

The importance of aerodynamic structure of the system, and the losses and leakages forming in the system has been observed experimental and affected parameters are evaluated.

Abstract

Purpose

Drawing on the social exchange theory, this study focuses on the impact of perceived organizational support (POS) and perceived supervisor support (PSS) on employees' adaptive (selling) behavior in a personal selling context. As part of the support-adaptive behavior relationship, the authors also explore the mediating role of psychological empowerment and the moderating role of customer orientation (CO).

Design/methodology/approach

Data were collected from 200 salespeople from the financial and pharmaceutical sectors in Turkey. Hypotheses were tested with hierarchical multiple regressions and hierarchical moderated regressions.

Findings

Supported salespeople feel more empowered in their jobs and show adaptive (selling) behavior. Our results also show that the impact of support on adaptive selling behavior through empowerment is stronger for salespeople with low CO.

Research limitations/implications

This study has two limitations: the generalizability of its findings and cross-sectional design. Still, it significantly contributes to support, empowerment and adaptive behavior literature.

Practical implications

By creating a supportive work environment and by training their managers to improve their support skills, organizations boost their employees' adaptability. Both of these support practices motivate employees to use their discretion in sales situations. Organizations should also evaluate and manage their employees' level of CO by conducting company surveys and by increasing top management communication.

Originality/value

This study tests the mediating role of psychological empowerment on the relationship between POS, PSS and adaptive behavior in the understudied personal selling context. The authors also test the moderating role of CO in the proposed model.
