This study has dealt with the gap in the literature, by probing the influence of innovation capability on business performance. This paper aims to test the moderation role of technological turbulence (TT) and market turbulence (MT) on the relationship between innovation capability (IC) and business performance (BP).

The study used a quantitative survey and a sample size of 579 departmental heads. Branch managers and permanent staff from the Greater Accra, Ashanti and Western Region in the Ghana telecommunication sector. The obtained data was analysed through the STATA 15.0 and AMOS statistical software package.

The empirical results from multiple linear regressions revealed that product/service innovation, process innovation, marketing innovation and administrative innovation had positive effects on business performance. The outcome of the moderation analysis further shown that technological turbulence positively moderates the relationship that existed between the various constructs of innovation capability and business performance indicating that technological turbulence significantly strengthens the relationship between these variables. On the contrary, market turbulence significantly weakens the relationship between the various innovation capability constructs and business performance.

Although this research has made significant contributions to both theory and practice, there are certainly some limitations and future research directions that need to be considered to appropriately position the study findings. Firstly, because of the limited sample size (579), further testing of these constructs needs to be carried out in future research using alternative data. Related to this, it would be prudent if the instruments and models developed in this research were tested in different industry contexts. Also, because the Ghana telecommunication sector is made up of foreign companies, comparative research could be conducted to compare the IC and performance of Ghana and the other countries where these companies operate. Indeed, analyses of IC and BP associated with the same companies in different countries may prove to be very beneficial in the global context. Secondly, this research used only TT and MT to test the moderating effect of ET on the association of IC with BP. Future research can include competition intensity which may change or confirm the outcome of these studies. Thirdly, only qualitative data were used for the measurement of IC and the level of BP. Therefore, future research could use quantitative or both qualitative and quantitative data to confirm if there will be significant differences in the results obtained.

Literature has examined the moderation effect of ET on different variables and relationships in different organizational settings. This study has tried to analyse the moderating effect of ET on the relationship of IC with BP. The outcomes of this study are similar to the previous research studies mentioned above, however, limited studies have been conducted on IC and its relationship with BP in the context of ET especially in the most vibrant sector of Ghana’s economy. These findings are very innovative and contribute enormously to literature and knowledge by indicating which moderating ET positively and significantly strengthens and the type which weakens the existing relationship between IC and BP within the Ghanaian telecommunication sector which no researcher has conducted. These findings will go a long way by aiding the players in this sector to tauten their IC wings to achieve resilient performance around the globe.

This will also contribute to the growth of Ghana’s economy as sources of revenue and employment. Additionally, the results obtained from this study will prompt managers to make more informed and effective decisions regarding innovation activities and the environments in which they operate.

This paper adds knowledge and literature to the existing ones. It is a new development in the research field of Ghana. This is the first journal this study has been submitted.

The purpose of this paper is to analyze the ability of turbulence models to model the flow field in the runner of a Francis turbine. Although the complex flow in the turbine can be simulated by CFD models, the prediction accuracy still needs to be improved. The choice of the turbulence model is one key tool that affects the prediction accuracy of numerical simulations.

This study used the SST k-w and RNG k-e turbulence models, which can both accurately predict complex flow fields in numerical simulations, to simulate the flow in the entire flow passage of a Francis turbine with the results compared against experimental data for the performance and blade pressure distribution in the turbine to evaluate the applicability of the turbulence models.

The results show that the SST k-w turbulence model more accurately predicts the turbine performance than the RNG turbulence model. However, the blade surface pressures predicted by the SST k-w turbulence model were basically identical to those predicted by the RNG k-e turbulence model, with both accurately predicting the experimental data.

Due to the lack of space, the method used to measure the blade surface pressure distributions is not introduced in this paper.

Turbine performance and flow field pressure in the runner, which are the basis of turbine preliminary performance judgment and optimization through CFD, can be used to judge the rationality of the turbine runner design. The paper provides an evidence for the turbulence selection in numerical simulation to predict turbine performance and flow field pressure in the runner and improves the CFD prediction accuracy.

This paper fulfils a test of the flow field pressure in the runner, which provide an evidence for judge the adaptability of turbulence model on the flow field in runner. And this paper also provides important evaluations of two turbulence models for modeling the flow field pressure distribution in the runner of a Francis turbine to improve the accuracy of CFD models for predicting turbine performance.

Innovation has been identified as a critical element to achieve firms' growth. The purpose of this study is to investigate the impact of chief executive officer (CEO) passion on firm innovation, including exploratory and exploitative innovation and examine the moderating roles of market and technological turbulence.

This study adopts the methodology of survey and uses multisource and time-lagged data of 146 firms in China. Seemingly unrelated regression (SUR) is used to test the hypotheses of this study.

This study finds that CEO passion promotes exploratory and exploitative innovation. Results also indicate that market turbulence strengthens the effect of CEO passion on exploratory and exploitative innovation, whereas technological turbulence weakens such an effect.

CEO passion is an important, positive affect which inspires CEOs to work for firms, but it has not yet received enough attention in the innovation literature. This study contributes to examining the impact of CEO passion on firm innovation and contributes to the contingency under which CEO passion influences firm innovation. Furthermore, this research finds that the moderating effects of market and technological turbulence are different in the relationship between CEO passion and firm innovation.

The stable and predictable agricultural, infrastructure, manufacturing, and energy economies of hard products have been followed by economies that offer softer products such as services, information, knowledge, health care, digitization, networking, globalization, entertainment, sustainability, and currently, well-being and happiness. Such soft market products are loaded with buyer–seller information asymmetries (BSIA) that create market risk, market uncertainty, market chaos, and ambiguity – all of which are specific types of market turbulence. In this context, this chapter investigates the phenomena of turbulence, specifically environmental turbulence whose major subsets are technological turbulence and market turbulence. We cite several recent geopolitical variables and events that have aggravated market turbulence such as Chinese economic invasion of global markets, global climate change, Brexit, international asylum-seeking migrations, artificial intelligence, and demonetization. We also define market turbulence as varied forms of BSIA for which both marketers and consumers must have appropriate joint responsibility. In addition, we focus on ethical and moral marketing responsibilities for reducing BSIA under each type of turbulence.

This chapter reports on research work which was a component of an independent review of the primary school curriculum renewal exercise that was commissioned by the Ministry of Education in Trinidad and Tobago and executed during 2012–2013. It examines how agencies functioned to engender educational change through education governance systems in the process of revising the curriculum. Turbulence Theory (Gross, 2014) was the tool used to explore the interactions among agencies. The research shows that turbulence occurred at various stages and that the outcome of interactions among the agencies that were in pursuit of educational change and equity was largely dependent on the extent of the turbulence and how it was managed. For example, the local Curriculum Planning Team (CPT) was able to learn from external consultants while firmly maintaining that they were the ones who had a deep understanding of the local context and should therefore have a major say in what was included in the curriculum. However, the CPT could do little to offset the severe turbulence caused when the political directorate mandated that there should be full-scale implementation of the revised curriculum without the benefit of a pilot. The role of socio-political contextual factors in the curriculum development process is highlighted.

The aim of this paper is to assess the ability of a stress-blended eddy simulation (SBES) turbulence model to predict the performance of a three-straight-bladed vertical axis wind turbine (VAWT). The grid sensitivity study is conducted to evaluate the simulation accuracy.

The unsteady Reynolds-averaged Navier–Stokes equations are solved using the computational fluid dynamics (CFD) technique. Two types of grid topology around the blades, namely, O-grid (OG) and C-grid (CG) types, are considered for grid sensitivity studies.

With regard to the power coefficient (Cp), simulation results have shown significant improvements of predictions using compared to other turbulence models such as the k-e model. The Cp distributions predicted by applying the CG mesh are in good agreement with the experimental data than that by the OG mesh.

The current study provides some new insights of the use of SBES turbulence model in VAWT CFD simulations.

The SBES turbulence model can significantly improve the numerical accuracy on predicting the VAWT performance at a lower tip speed ratio (TSR), which other turbulence models cannot achieve. Furthermore, it has less computational demand for the finer grid resolution used in the RANS-Large Eddy Simulation (LES) “transition” zone compared to other hybrid RANS-LES models.

To authors’ knowledge, this is the first attempt to apply SBES turbulence model to predict VAWT performance resulting for accurate CFD results. The better prediction can increase the credibility of computational evaluation of a new or an improved configuration of VAWT.

Environmental turbulence represents a double-edged sword, simultaneously fueling and hindering a firm’s entrepreneurial orientation (EO). Drawing on the theories of EO and network relationships, this study aims to develop and test a conceptual model that provides a nuanced account of the relationship between environmental turbulence and firm EO.

Data for this study were collected using a survey of high-technology firms in Hsinchu Science Park (HSP) in Taiwan. Questionnaires were mailed to 297 high-technology firms in the semiconductor, photoelectric and communication industries within HSP. Completed questionnaires were received from 94 firms, which included responses from 94 research and development managers and 462 employees.

The results reveal that the degree of environmental turbulence exhibits an inverted U-shaped relationship with a firm’s EO. Moreover, this relationship is positively moderated by network relationships between firms, but negatively moderated by organizational inertia.

The empirical and conceptual findings have important implications for understanding EO, because the findings explain causal relationships that transform a firm’s interactive and inner control capabilities into firm-level results.

Companies need guidance on how to operate in turbulent environments to improve their innovative performance. However, few studies have been done specifically about how to market and technological turbulence affects the innovative performance in emerging markets. This paper aims to propose model with market turbulence, technological turbulence and firm’s bricolage behavior as antecedents of organizational innovativeness.

Two conceptualizations of the role of environmental turbulence are examined as follows: that market turbulence and technological turbulence are established as direct antecedents to organizational innovativeness performance; and the model has a mediating effect through the bricolage behavior. In this sense, the strengths of the paths differ depending on the presence of bricolage. Data were collected from 215 firms operating in Brazil, analyzed using the partial least squares (PLS)-structural equation modeling (SEM) technique as a quantitative method to test the hypotheses.

The results indicate that the mediating effect evidenced by the bricolage behavior was supported. In other words, the path from market and technological turbulence to organizational innovativeness is significantly better when permeated by bricolage behavior in the organization.

It can be suggested to conduct similar research with larger sample size and applying control variables such as the size of the company, as smaller companies have less access to resources and maybe the engagement in bricolage can be even more substantial for them to keep innovating and to remain competitive in times of turbulence.

Some managerial recommendations and implications are provided. Managers should recognize the possible improvements in the organizational innovativeness development by actively including the bricolage behavior among their companies’ activities.

The theoretical contribution to the academic knowledge lies in corroborating with previous studies, which pointed out that bricolage has an influence on a firm’s innovativeness and some studies, which address perspectives in the organizational learning field.

The purpose of this paper is to investigate the influence of green product innovation performance (GPIP) on a firm’s financial performance (i.e. a firm’s profitability and risk). In addition, it has adopted the resource-based view and contingency theory to explore how GPIP and a firm’s financial performance relationship is manifested when subject to the moderating role of a firm’s market resource intensity and certain environmental factors, such as technological turbulence and market turbulence.

Data were collected from 202 publicly listed Thai manufacturing firms. This research has used hierarchical regression analyses to empirically test the proposed research hypotheses.

The findings reveal that GPIP exerts a significant influence on a firm’s financial performance, i.e. higher the GPIP, higher the firm’s profitability and lower the firm’s financial risk. Moreover, findings support the theoretical assertions that the higher level of market resource intensity, market turbulence and technological turbulence further strengthens GPIP and a firm’s financial performance relationship.

By considering the independent moderating role of market resource intensity, market turbulence and technological turbulence, this research has contributed to reconcile the previously disparate findings regarding the GPIP and a firm’s financial performance relationship. Moreover, this research has highlighted the role of the essential moderators that business managers must understand and adjust to capitalize on and achieve superior financial performance.

Customer relationship management (CRM) is instrumental to attain and sustain organizational competitive advantage. Innovation in terms of CRM adoption is the key to gain competitive advantage, and being innovative is dependent on how well organizations know about changing demands of customers and their changing ways to gain access to the market. There is hence a need to develop ongoing empirical insights from diverse management perspectives into the effect of CRM adoption on organizational performance. In this context, the purpose of this study is to develop empirical insights in relation to the moderation of technological turbulence in the banking sector.

Primary data were collected and analyzed from 277 CRM staff-members of the banking sector in Pakistan to test a conceptual model. Frequencies of demographics are calculated with correlation and regression analyses using SPSS. The correlation analysis was performed to identify the direction that exists between the dependent and independent variables, and the regression analysis was performed to study the strength/intensity of the independent variable over the dependent variable. Moderating regression analysis was performed to find the moderation effect of technological turbulence on CRM adoption and organizational performance.

The CRM adoption has a critical positive impact on organizational performance in the settings of business-to-customer (B2C) perspective in the banking sector. Moreover, the results uncover that improved client satisfaction through CRM adoption prompts better organizational performance in the B2C organization. The authors also have found that technological turbulence has a negative guiding impact on the association linking with CRM adoption, as well as organizational performance.

The conceptual model that is proposed in this study and supported by empirical insights offers researchers to develop future research studies on the moderating role of technological turbulence to analyze the influence of CRM adoption on organizational performance.

The empirical insights of this study are valuable for the professionals in the banking sector and other B2C organizations to enrich their organizational performance through CRM adoption while considering the moderating role of technological turbulence.

Based on an empirical study, in support of an original conceptual model, the insights of this paper contribute to the extant literature in the CRM, bank marketing and management, service management, B2C marketing and the emerging economy knowledge streams.
