Abstract
Purpose
This paper aims to investigate the usability of the nickel copper zinc ferrite with the composition Ni0.4Cu0.2Zn0.4Fe1.98O3.99 for the realization of high-temperature multilayer coils as discrete components and integrated, buried function units in low temperature cofired ceramics (LTCC).
Design/methodology/approach
LTCC tapes were cast and test components were produced as multilayer coils and as embedded coils in a dielectric tape. Different metallization pastes are compared. The properties of the components were measured at room temperature and higher temperature up to 250°C. The results are compared with simulation data.
Findings
The silver palladium paste revealed the highest inductance values within the study. The measured characteristics over a frequency range from 1 MHz to 100 MHz agree qualitatively with the measurements obtained from toroidal test samples. The inductance increases with increasing temperature and this influence is lower than 10%. The characteristic of embedded coils is comparable with this of multilayer components. The effective permeability of the ferrite material reaches values around 130.
Research limitations/implications
The research results based on a limited number of experiments; therefore, the results should be verified considering higher sample sizes.
Practical implications
The results encourage the further investigation of the material Ni0.4Cu0.2Zn0.4Fe1.98O3.99 for the use as high-temperature ferrite for the design of multilayer coils with an operation frequency in the range of 5-10 MHz and operation temperatures up to 250°C.
Originality/value
It is demonstrated for the first time, that the material Ni0.4Cu0.2Zn0.4Fe1.98O3.99 is suitable for the realization of high-temperature multilayer coils and embedded coils in LTCC circuit carriers with high performance.

Abstract
In September 1985, eight sets of children's books from Australia began an odyssey that will take them into all fifty states and Canada by the end of 1988. The books— and the resource, reference and display materials that accompany them—were chosen specifically for their value in introducing non‐Australians to Australia and her children's literature. They also provide an ideal starting point for library collection development.

Abstract
Purpose
The purpose of this paper is to explore the theoretical mechanisms that underlie the negative effects of low customer density on shoppers' emotions and behavioural responses in retail settings.
Design/methodology/approach
This study uses three different qualitative techniques to explore the research question: semi‐structured interviews, shopping with consumers, and focus groups.
Findings
Three major issues contribute to unfavorable consumer responses to low customer density levels in retail stores: exposure to undesired social influence from sales personnel; loss of social cues and evaluation criteria; and lack of social stimulation.
Practical implications
The findings of this research assist store managers to resolve the problems associated with low customer density in retail stores. For example, the results suggest that the negative effects of low customer density can be mitigated by providing appropriate training for sales staff as well as by actively communicating the quality, price level, and image of the store.
Originality/value
Empirical evidence shows that the effects of customer density on shopper outcomes follow an inverted U‐shaped trend. Previous research has focused on explaining the negative consequences of high customer density, while the explanatory mechanisms for the negative effects of low customer density remain largely unclear. This research partially fills this gap in the literature by identifying the psychological processes that account for the negative effects of low customer density.

Abstract
Purpose
This study examines the interactions between entrepreneurial orientation, supply chain resilience (SCRES) as well as the financial and commercial dimensions of business performance.
Design/methodology/approach
Drawing on a literature review, the authors develop a research model to identify positive relationships between five specific dimensions of entrepreneurial orientation, SCRES and business performance based on the dynamic capabilities view. The hypotheses are then empirically validated by applying partial least squares structural equation modeling (PLS-SEM) on survey data obtained from a questionnaire and 168 global companies.
Findings
The results partially support the hypotheses and suggest that entrepreneurial activities complement the resilience of supply chains to sudden disruptions and therefore also foster competitive advantage.
Originality/value
The relationships between entrepreneurial orientation, SCRES and business performance are examined and validated empirically in a single model, bridging the gap between these distinct research streams and shedding further light on supply chain risk management.

Abstract
Purpose
This paper integrates research on demand- and supply-side risk management practices to better explain how to achieve competitive advantage in dynamic business conditions. The purpose of this study is to develop a model linking supply chain flexibility, agility, robustness and resilience and to investigate its relationships and impact on business performance.
Design/methodology/approach
The authors conduct a review of existing literature to derive their hypotheses and operationalize the respective constructs. The formulated research model is then validated applying partial least squares structural equation modeling on survey data from 89 multi-national companies based in Europe.
Findings
The authors find a significant positive relationship between supply chain flexibility and supply chain agility as well as supply chain robustness and supply chain resilience, respectively. Additionally, it is argued that supply chain flexibility, agility and resilience have significant positive impact on individual dimensions of business performance.
Originality/value
The relationships between supply chain flexibility, agility, robustness, resilience and business performance are investigated and empirically validated altogether in a single model for the first time, providing a clear separation of these terms and shedding further light on the management of supply chain risks.

Abstract
Purpose
The purpose of this paper is to examine the relationships among the experiential quality (EQ) dimensions, experiential satisfaction (ES), experiential involvement (EI), host city image (HCI), experiential equity (EE), spectator affection (SA) and experiential loyalty (EL) in the sport context.
Design/methodology/approach
The data used in this study were based on a sample of 674 spectators from the finals of the men’s and women’s football tournaments held at the Maracanã Stadium in Rio, indicating that the proposed model fitted the data.
Findings
Findings show that the six EQ dimensions physical environment quality, outcome quality, access quality (AQ), game quality, trip quality (TQ) and security quality (SQ), EI, EE, HCI and SA positively influence ES. Also, EI moderates the relationship between HCI and EL. Moreover, EL is influenced by EI, HCI, SA and ES.
Practical implications
Results will assist sport management in developing and implementing market-orientated service strategies to increase the EQ dimensions, ES, EI, EE, HCI and SA in order to increase EL.
Originality/value
This study provides data that result in a better understanding of the relationships among the EQ dimensions, ES, EI, HCI, EE, SA and EL in the sporting context.

Abstract
Purpose
The main objective of this research is to investigate the factors that influence consumer purchase decisions for halal products before and during the COVID-19 pandemic, based on the Engel-Kollat-Blackwell (EKB) theory.
Design/methodology/approach
The research was conducted as a survey. The influencing factors were determined based on the grey relational analysis (GRA) approach.
Findings
The findings indicate before the COVID-19 pandemic, consumers mainly purchased halal products based on four key factors: purchasing experience, certification label, Internet searches and past consumption experience. However, during the pandemic, the ranking and factors have changed to six indicators, which are past consumption experience, purchasing experience, certification labels, standardized specifications, Internet searches and halal certification labels.
Research limitations/implications
The study was limited by the sample size and geographical area. Nevertheless, the findings could be further explored by expanding related theories toward understand human decisions based on spiritual beliefs.
Practical implications
The findings of this study have important implications for research, practice and society. Understanding the factors influencing halal purchase decisions before and during the pandemic can help businesses, policymakers and halal certification bodies to better cater to consumers' needs and preferences and ensure the continued growth and development of the halal industry.
Originality/value
This study evaluates halal purchasing decisions between periods of certainty and uncertainty by using the GRA. Changes in halal consumption and purchase decisions in response to COVID-19 pandemic have become an emerging topic of discovery. The study addresses the gap in the literature regarding changes in consumer decision pattern.

Abstract
Purpose
The purpose of this paper is to discuss a numerical study of the flow over a wing representative of a large civil aircraft at cruise condition. For each Mach number considered, the numerical simulations indicate that critical angle of attack exists where the separated region increases in size and begins to oscillate. This phenomenon, known as transonic shock buffet, is reproduced by the unsteady simulation and much information can be extracted analysing location, amplitude and frequency content of the unsteadiness.
Design/methodology/approach
Reynolds-averaged Navier-Stokes simulations are conducted on a half wing-body configuration, at different Mach numbers and angles of attack. Different turbulence models are considered, and both steady-state results and time-accurate simulations are discussed.
Findings
The high number of cases presented in this study allows the creation of a database which, to the authors’ knowledge, has not been documented in literature before. The results indicate that, while high-fidelity approaches can improve the quality of the results, the URANS approach is capable of describing the main features of the buffet phenomenon.
Research limitations/implications
The presence of a turbulence model, despite allowing the description of the main unsteady phenomenon, might be insufficient to fully characterise the unsteadiness present in a transonic flow over a half wing-body configuration. Therefore, researchers are encouraged to verify by means of experimental investigation or high-fidelity approach the results issued from a Reynolds-averaged Navier-Stokes equations.
Practical implications
The results presented clearly indicate that, despite what proposed in recent research papers, transonic buffet can be described by means of time-accurate Reynolds-averaged Navier-Stokes equations. Such an approach is popular in the aeronautical industry because of its reduced costs, and could be used for wing design.
Originality/value
In this paper, the authors used a classical approach to tackle the known problem of transonic buffet in three-dimensional configurations. The large number of results presented can be used as a database for future numerical simulations and experiments, and allow to describe the flow-physics of the buffet unsteadiness on a half wing-body configuration.

Abstract
Purpose
The importance of integrating both internal and external knowledge into the product/service innovation process has been widely recognized in the knowledge management and innovation literature. Likewise, the role of the marketing and sales function as a driver of innovation has been stressed because of its market-facing role. However, limited research has investigated the complementarity of both internal and external knowledge regarding product/service innovation performance in a marketing context. The purpose of this study is to analyze marketing departments’ role in accessing internal and external knowledge resources (i.e. marketing-specific relational capital [RC]) to reach improved product and service innovation performance.
Design/methodology/approach
The analysis uses empirical evidence collected by a structured survey of 346 respondents representing marketing and sales functions in Spanish companies.
Findings
The survey revealed that marketing-specific internal relational capital at the department and inter-department levels, as well as noncustomer external RC, are directly associated with product/service innovation performance. Further, the analyses show that the relationship between customer-specific RC and innovation performance is mediated by other types of RC, making it a fundamental antecedent to the innovation process. Finally, significant differences in marketing-specific RC subcomponents were found between business-to-consumer (B2C) and business-to-business (B2B) firms.
Originality/value
This study makes a valuable contribution to marketing and management literature by revealing the types of social interactions in the marketing function that enable access to knowledge sources that promote successful product/service innovation.

Abstract
Purpose
The aims of this paper are to identify and classify the knowledge resources that shape intellectual capital (IC) within the marketing function, to develop and validate a related scale and to demonstrate the scale's applicability in an empirical context.
Design/methodology/approach
A literature-based approach was adopted to identify and classify knowledge assets in the field of marketing. The new scale's content was then tested in a number of companies with different profiles. A subsequent survey of a representative sample of 346 Spanish firms sought to validate the scale and to assess those companies' marketing-related IC.
Findings
The literature search provided the basis for a marketing-related IC architecture comprising three main categories, nine subcategories and eighty items whose validity was tested and confirmed. The survey revealed that marketing-specific human capital (HC) is the most developed knowledge resource in Spanish firms, followed by marketing-specific relational capital (RC), while marketing-specific structural capital (SC) is the least developed. Significant differences were also found among companies with different profiles (B2C vs B2B, high-tech vs low-tech and manufacturing vs services).
Originality/value
This study makes a valuable contribution to the IC literature as one of the first to deploy the general IC framework in a specific functional area (here: marketing and sales) for more meaningful and in-depth assessment of firm-specific knowledge resources.
