Besides, the application of GST in environment protection and the integration of the GST and intelligent algorithm became more popular.Originality/valueThe comprehensive bibliometrics analysis and visualization demonstration were conducted, presenting the interdisciplinary characteristics, major research topics and research frontiers in this field.
Structure optimization and cooling performance of a heat sink with discontinuous arc protrusions impacted by nanofluid confined slot jet impingement
Authors: Tang Zhiguo , Deng Feng , Ji Yongtao , Cheng Jianping 
Published: November 2022

Purpose
The purpose of this paper is to improve the overall heat transfer performance and the temperature uniformity of the heat sink and to explore the effects of the jet Reynolds number and the nanoparticle volume fraction of the nanofluids on the flow and heat transfer performance.

Design/methodology/approach
A heat sink with discontinuous arc protrusions in the wall jet region is proposed for confined slot jet impingement. A sloping upper cover plate is added to improve the heat transfer effect in this area. An Al2O3–water nanofluid is selected as the working fluid of the jet for better heat transfer. The Standard k-e turbulence model is used for numerical calculation. The key structural parameters of the heat sink are optimized by the response surface method and a genetic algorithm. The effects of the jet Reynolds number (Re) and the nanofluid concentration (ϕ) on the flow and heat transfer performance of the optimized heat sink are investigated.

Findings
The average Nusselt number of the optimal heat sink is 8.2% higher and the friction resistance is 5.9% lower than that of the initial flat plate heat sink when ϕ = 0.02 and Re = 8,000. The discontinuous arc protrusions and the sloping upper cover plate substantially enhance the heat transfer in the later stage of jet development, improving the temperature uniformity of the heat sink. The maximum temperature difference of the optimal heat sink is 28.1% lower than that of the flat plate heat sink at the same nozzle height. As the jet Reynolds number and the nanofluid particle concentration increase, the Nusselt number of the optimized heat sink and the friction coefficients increase, resulting in a decrease in the evaluation coefficient. However, the overall temperature uniformity of the heat sink is improved under all conditions.

Originality/value
The novel heat sink structure provides a new way to enhance the heat transfer and temperature uniformity of confined slot jet impingement. The flow and heat transfer performance of the heat sink impinged by confined slot jet of nanofluids are obtained. The combination of response surface method and genetic algorithm can be applied to the multi-objective optimization of heat resistance and flow resistance of heat sink.

Authors: Adekoya Clement Ola , Ureki Isioma Alexis , Alade Adesola Victoria 
Published: November 2022

Purpose
The quest for sustainable food security (SFS) is fundamental to United Nations Sustainable Development Goals. In furtherance of their pivotal role in providing the required information resources in support of education and research, libraries are expected to assist the economy in ensuring SFS. The purpose of this study is to investigate how libraries provide information to support research in agriculture towards the attainment of SFS in Nigeria.

Design/methodology/approach
Descriptive research design was used for the study. Interview and questionnaire were used as the instruments of data collection.

Findings
This study found that the extent of use of library information resources for SFS in Nigeria is high. Libraries, though facing some challenges, contribute significantly to the attainment of food security in Nigeria. It was recommended that libraries should intensify efforts to embark on media literacy programmes and provide information resources for research on agriculture and food production with a view to actualising food security goals specified in Sustainable Development Goals. Libraries should be well-funded to acquire the relevant information resources to aid research into food security and end hunger and poverty across the world.

Practical implications
This study suggests having better sponsored libraries that can perform as required in advancing agricultural information needs.

Originality/value
This study is a creative attempt to know how libraries can contribute to SFS through the provision of information to farmers and lecturers in agriculture.
Examining the link between integrated management systems and firm performance: do the integration strategies matter?
Authors: Wang Jiangang , Liu Fanghong 
Published: November 2022

PurposeThis study attempts to examine the performance differences between firms with and without integrated management systems (IMSs), and the impact of three integration strategies (i.e. implementing quality management system (QMS) first, then environmental management system (EMS) (QMS + EMS); implementing EMS first, then QMS (EMS + QMS); implementing QMS and EMS simultaneously (QMS − EMS)) on firm performance to reveal the IMS–performance relationship and provide empirical evidence.Design/methodology/approachTwo panel datasets were collected during 2009–2019. This study used the Mann–Whitney non-parametric test and a sample of 33,155 observations from 4,316 Chinese listed firms to compare the performance differences between the IMS and non-IMS groups through performance indicators. This study also examined the effects of three integration strategies on firm performance using a cross-sectional time-series feasible generalized least squares (FGLS) regression model and a sample of 11,289 observations from 2,037 firms.FindingsThe results show that significant performance differences exist between IMS and non-IMS firms; however, the performance of firms with an IMS is not always better than that of firms without IMS. Furthermore, the simultaneous integration strategy has a positive impact, whereas sequential integration strategies (QMS + EMS and EMS + QMS) negatively affect firm performance. Compared with the EMS + QMS strategies, the QMS + EMS strategies have a more prominent effect on firm performance. Simultaneous strategies are more effective than sequential strategies.Practical implicationsFirms should fully consider the potential benefits and costs associated with the difficulties of IMS implementation and the implementation order of different management systems and the potential effects of the management systems in different conditions. Firms also should try to develop internal capabilities through implementing different integration strategies.Originality/valueBy comparing performance differences between firms with and without IMS, this study enriches the understanding of the performance benefits of IMS implementation in the Chinese context. By examining the impact of integration strategies that follow different sequences on firm performance, this study promotes an in-depth understanding of the integration strategies and their performance implications beyond simple descriptions and also provides new insights into operations strategy models.
Taking a different view: theorizing on firms' development toward an integrative view on socially sustainable supply chain management
Authors: Hohn Marlene M. , Durach Christian F. 
Published: November 2022

PurposeDespite a surge in public and academic interest in the social sustainability conduct of firms, only few firms have taken responsibility for the social issues in their supply chains. This study seeks to extend our theoretical understanding of why some firms grow toward accepting this type of responsibility while others do not.Design/methodology/approachThe authors conduct a systematic literature review for the purpose of theory building. Building on Gao and Bansal's distinction of instrumental and integrative views on business sustainability (2013, DOI 10.1007/s10551-012-1245-2) as well as corporate social responsibility development research, the authors review socially sustainable supply chain management (social SSCM) literature to theorize the interplay of driving factors that underly firms' choice to refrain from, start or deepen their engagement in social SSCM.FindingsThe authors propose an overview of the presumed mechanisms underlying the development of a reluctant, a purely instrumental or an integrative view on social SSCM. Among other things, the authors propose that it seems highly unlikely for conventional, profit-oriented firms to develop beyond an instrumental view on social SSCM.Originality/valueThis study conceptually extends current research on social SSCM by offering insights on how firms are driven to engage in it. This study offers first thoughts that should help managers and other stakeholders better understand the social SSCM potential of firms and how to realize this potential effectively.
The expansion and stability of two-sided platform ecological networks: an analysis based on the leverage theory of tying
Authors: Qian Zhang , Wei Cui , Chao Tang , Yan Luo 
Published: November 2022

PurposeWith the rapid development of the digital economy, an increasing number of digitalized two-sided platforms have deployed the tying strategy to leverage their market power from the core two-sided product to other two-sided products in the competitive market, which transforms the competition among single platforms into that among platform ecological networks. To clarify the mechanism of the formation of the digital platform ecological networks, this paper aims to analyze the expansion and stability of platform ecology by exploring the impacts of network externalities and sellers’ heterogeneity on the tying strategy of two-sided platforms.Design/methodology/approachThis paper develops a game model of two-sided platforms based on Choi and Jeon (2021), which highlights the decisive influence of non-negative price constraints (NPC) on platforms’ tying motivation. Taking the operating systems market as an example, we expand from the perspective of platform service differences to relax the NPC and explore the internal logic of platform ecosystem expansion.FindingsPlatforms have an incentive to charge lower prices or even subsidize buyers when the network externalities on the sellers’ side are relatively strong. When the product is highly differentiated and heterogenous, platforms are motivated to tie to capture more buyers with a lower price and grab excess profits from sellers. Eventually, tying is able to consolidate the two-sided platform ecological networks by excluding competitors, capturing user value and deterring entry.Originality/valueIn order to describe the characteristics of platform ecological network more generally, this paper extends the research based on the analyses of Choi and Jeon (2021) by (1) allowing horizontal differences between tied products and (2) relaxing the NPC. Unlike Choi and Jeon (2021), this paper allows platforms to charge users of two-sided platforms at negative prices (or to subsidize them). (3) Setting simultaneous pricing in two-sided platforms. Classical two-sided market theory stresses that the presence of cross-network externalities can give rise to a “chicken and egg” problem.
Loss aversion and risk propensity in public budgeting
Authors: Litton Eric 
Published: November 2022

PurposeThis paper applies the theory of loss aversion to public budgeting. It seeks to understand how loss aversion affects recommended budget amounts in two scenarios, one with explicit and one with implied risk levels. It also furthers the understanding of how the personality trait of risk propensity moderates recommended budget amounts in these scenarios.Design/methodology/approachUtilizing original data gathered from experimental vignettes, 339 US-based participants provided budget recommendations on two separate federal education programs. Participants were current budget professionals and master's-level students. One program utilizes a risky choice frame scenario while the other uses a goal frame scenario.FindingsParticipants are more likely to select a risky program option when the options are framed in terms of loss. Additionally, participants recommended larger budgets when they select the riskier program option. When presented with program goals, participants budget more when the goals are framed in terms of loss as opposed to gains. Results on participant risk propensity are mixed.Practical implicationsThe discussion section includes multiple recommendations on how managers can approach budgeting with the intent of obtaining the most efficient budget allocation for the programs under their control.Originality/valueThe study is the first to examine framing and risk propensity in budgeting using two different types of framed messaging. Additionally, it is the only study to ask participants to recommend a budget amount after selecting a risky choice option. Therefore, results are more relevant to the entire process of public budgeting. Also, the study includes a mixture of participants with and without finance experience, providing insight into how different public employees allocate funds.
Which loyalty program do customers prefer: a coalition program or a single-firm program?
Authors: Shirai Miyuri 
Published: November 2022

Purpose
This study aims to examine consumers’ responses to two types of loyalty programs: coalition and single-firm programs. This study explains the mechanism underlying the link between this program structure and consumers’ program evaluation by incorporating the type of firm offering the program (i.e. a more hedonic or a more utilitarian disposition), the type of rewards (i.e. presence/absence of experiential rewards) and consumers’ reactance.

Design/methodology/approach
Two online experiments were employed to test the proposed framework.

Findings
Consumers commonly preferred a coalition program to a single-firm program. This preference for the coalition program was strengthened when a utilitarian-dominant firm offered the program. Additionally, consumers evaluated the program lower when a utilitarian-dominant firm provided experiential rewards. Furthermore, situational reactance toward the program mediated the effect of the program structure on the program evaluation.

Practical implications
This study’s findings suggest that firms should consider whether the value consumers predominantly perceive from the firms is utilitarian or hedonic when launching coalition programs. Consumers may not be pleased by the coalition programs offered by hedonic-dominant firms as much as those provided by utilitarian-dominant firms. Moreover, this study’s results help design reward options. Consumers may not well evaluate the inclusion of experiential rewards when offered by utilitarian-dominant firms. For utilitarian-dominant firms, rewards requiring less time and effort may be more suitable.

Originality/value
This research significantly contributes to the literature on loyalty programs. This study showed that consumers viewed single-firm and coalition programs differently and elucidated the mechanism behind the response.

Authors: Hamzah N. , Samat M.H. , Johari N.A. , Faizal A.F.A. , Hassan O.H. , Ali A.M.M. , Zakaria R. , Hussin N.H. , Yahya M.Z.A. , Taib M.F.M. 
Published: November 2022

Purpose
The purpose of this paper is to investigate the structural, electronic and optical properties of pure zinc oxide (ZnO) and transition metal (Tm)-doped ZnO using Tm elements from silver (Ag) and copper (Cu) by a first-principles study based on density functional theory (DFT) as implemented in the pseudo-potential plane wave in CASTEP computer code.

Design/methodology/approach
The calculations based on the generalized gradient approximation for Perdew-Burke-Ernzerhof for solids with Hubbard U (GGA-PBEsol+U) were performed by applying Hubbard corrections Ud = 5 eV for Zn 3d state, Up = 9 eV for O 2p state, Ud = 6 eV for Ag 4d state and Ud = 9.5 eV for Cu 3d state. The crystal structure used in this calculation was hexagonal wurtzite ZnO with a space group of P63mc and supercell 2 × 2 × 2.

Findings
The total energy was calculated to determine the best position for Ag and Cu dopants. The band structures and density of states show that Tm-doped ZnO has a lower bandgaps value than pure ZnO because of impurity energy levels from Ag 4d and Cu 3d states. In addition, Ag-doped ZnO exhibits a remarkable enhancement in visible light absorption over pure ZnO and Cu-doped ZnO because of its lower energy region and extended wavelength spectrum.

Originality/value
The results of this paper are important for the basic understanding of the 3d and 4d Tm doping effect ZnO and have a wide range of applications in designing high-efficiency energy harvesting solar cells.
Influential dynamic capabilities and small and medium enterprises' internationalization success: mediating role of international entrepreneurial orientation
Authors: AlShehhi Moza Rashed , Cherian Jacob Poopada , Farouk Sherine , Al Nahyan Moza 
Published: November 2022

Purpose
This study aims to analyze how international entrepreneurial orientation mediates the relationship between influential dynamic capabilities and the internationalization success of small and medium-sized enterprises (SMEs) in the context of the United Arab Emirates (UAE).

Design/methodology/approach
Adopting a quantitative approach, the researchers designed a questionnaire based on an extensive literature review and used structural equation modeling to ascertain the mediating role of international entrepreneurial orientation in the relationship between influential dynamic capabilities and SMEs' internationalization success.

Findings
The findings of this study indicate that international entrepreneurship orientation mediates the relationship between dynamic capabilities and internationalization success, as the indirect impact value is greater than the direct effect value for the relationship. Because the existence of the mediator in the model has no significant impact on the model's direct effects, full mediation is the most appropriate mediation type.

Research limitations/implications
This study has some limitations. One of the major limitations of this study relates to the limited finances of the incumbent, as the questionnaires were delivered to the respondents via email, but the incumbent had to follow up with phone calls and reminders. Second, this study mainly relied upon primary data and analysis based on the use of qualitative techniques; in future, researchers can incorporate qualitative aspects using interviews and other qualitative analysis tools and techniques. Third, limitation relates to sample size, as the sample size of research was above 500 but was limited to just UAE. Future researchers can conduct a cross-sectional analysis to determine the mediating role of different factors for the promotion of internationalization.

Practical implications
This study highlights the fundamental factors affecting the internationalization of SMEs in the UAE context, which has rarely been discussed. This study broadens the scope of internationalization by discussing its impact on SMEs' financial and non-financial performance.

Social implications
This study will contribute to the advancement of current information about the elements that impact the internationalization of SMEs and develop a new framework for analyzing SMEs' internationalization in the UAE.

Originality/value
This study contributes to the literature by developing and testing a framework based on a comprehensive literature review to include different factors and their constructs that impact the potential internationalization of SMEs in developing economies. This study identifies and addresses a research gap regarding the relationship between internationalization and company performance among UAE SMEs.
The effect of innovation on tourists’ revisit intention toward tourism destinations
Authors: Lyu Jiaying , Li Yao , Mao Zhenxing , Huang Huan 
Published: November 2022

Purpose
Drawing on Schumpeter’s theory of innovation and stereotype content model, this study aims to arrive at an integrated model that relates destination innovation type, destination innovativeness and revisit intention to uncover more about the drivers and outcomes of destination innovativeness from a consumer-centric perspective.

Design/methodology/approach
Three studies, including content analysis of news media, an onsite survey and an online survey in Chinese special featured towns, were conducted.

Findings
This study develops a consumer-centric destination innovation measure. The results reveal that input innovation and product innovation positively influence revisit intention through the serial mediation of destination innovativeness and perceived competence.

Research limitations/implications
As the data was collected from tourists in China, any generalization of the results to other regions should be made with caution; accordingly, replication is needed to test the proposed model in different cultural contexts. Second, during the onsite data collection period, special featured town destinations were still recovering from the COVID-19 pandemic, which may have affected the perceptions of tourists. Third, the second round of data was collected using an online survey, which may have introduced bias due to a potential lack of representativeness. Fourth, some potential missing variables could also influence the links among innovation, destination innovativeness and revisit intention.

Originality/value
This study presents the first empirical test of the impact of innovation type and innovativeness on tourists’ response to tourism destinations. The results of this study could guide destinations to deliver more effective consumer-centric innovations to generate competitiveness.
