Abstract

This paper reports some investigative results obtained through the application of differential geometry to the array manifold of a direction finding (DF) sensor array. It emphasises the crucial but so far disregarded role of the array manifold in the performance of subspace‐based direction finding (DF) algorithms and then proceeds to a compact mathematical analysis of the array manifold using the tools of differential geometry. The results thus obtained are used to quantify the effects of the array manifold properties on the performance of a DF system and to design superresolution sensor arrays.

Abstract

This chapter explores how perceived product innovation influences brand loyalty among UK Apple users, extending the technology acceptance model. Using a quantitative approach, data were collected from 101 respondents via an online survey and analysed using SPSS. Objectives included examining the mediating role of perceived product usefulness and ease of use, exploring the relationship between product/brand attitudes and brand loyalty and assessing gender's impact on loyalty perceptions. Findings reveal a significant positive relationship among variables, with perceived product usefulness and ease of use jointly mediating the link between product innovation and attitude, affecting brand loyalty. Gender was found to have no moderating effect. The research contributes by highlighting these mediating effects and deepening understanding of product innovation's impact on loyalty. Managerially, prioritising innovation, usefulness and ease of use can enhance satisfaction and loyalty. Future research could explore additional variables to enrich understanding further.

Abstract

Purpose

The purpose of this paper is to examine the existence of operational stickiness, and explores the relationship between operational stickiness and the likelihood of survival. Furthermore, the authors investigate this relationship in different manufacturing industries.

Design/methodology/approach

Using a large sample of more than 200,000 new manufacturing small and medium enterprises between 2000 and 2013 in China, the authors use the survival analysis method to investigate the non-linear relationship between operational stickiness and the likelihood of survival.

Findings

The authors demonstrate the existence of operational stickiness, such as inventory stickiness, property, plant, and equipment (PPE) stickiness, and labor stickiness. Next, the authors find the inverted U-shaped relationship between operational stickiness and the likelihood of survival. Furthermore, the authors document the differential effect of operational stickiness on the likelihood of survival in different industries.

Practical implications

Managers can improve the firm’s likelihood of survival by maintaining a moderate inventory stickiness and PPE stickiness. However, managers should not adopt sticky labor management in manufacturing industries.

Originality/value

This paper may be the first study to demonstrate the existence of operational stickiness, and confirm the inverted U-shaped relationship between operational stickiness and the likelihood of survival.

Abstract

Purpose

This study investigates whether the underrepresentation of women in executive-level roles within the supply chain management (SCM) field is justified or the result of gender injustices. The analysis examines if there is a gender compensation gap within executive-level SCM roles and whether performance differences or other observable factors explain disparities.

Design/methodology/approach

Publicly reported executive compensation and financial data are merged to empirically test if gender differences exist and investigate whether the underrepresentation of women in executive-level SCM roles is unjust.

Findings

Women occupy only 6.29% of the positions in the sample of 447 SCM executives. Unlike prior studies, we find that women executives receive higher compensation. The analysis does not identify observable factors explaining the limited inclusion of women in top-level roles, suggesting that gender injustices are prevalent in SCM.

Research limitations/implications

This study only considers observable factors and cannot conclusively determine if discrimination is occurring. The low level of inclusion of women in executive roles suggests that gender injustice is intrinsic within the SCM profession. These findings will hopefully motivate firms to undertake transformative actions that result in outcomes that advance gender equity, ultimately leading to social justice for female SCM executives.

Originality/value

The use of social justice and feminist theories, a focus on SCM roles, and an empirical methodology utilizing objective measures represents a novel approach to investigating gender discrimination in SCM organizations, complementing prior survey-based studies.

Abstract

Purpose

The purpose of this paper is to examine the impact of operational stickiness on product quality. Particularly, it analyzes the moderating effect of product diversification on the relationship between operational stickiness and product quality of exporting firms from China.

Design/methodology/approach

Using a sample of 3,567 exporting firms between 2002 and 2012 in China, this paper develops a fixed effect model to demonstrate the nonlinear relationship between operational stickiness and product quality.

Findings

Results show that operational stickiness has an inverted U-shaped impact on product quality, while inventory stickiness, property, plant and equipment (PPE) stickiness and labor stickiness are used to measure operational stickiness. Furthermore, the impact of operational stickiness on product quality is found to be moderated by product diversification.

Practical implications

Managers can achieve an optimal level of product quality by adjusting the level of operational stickiness. Firms with excessive operational stickiness should appropriately reduce the degree of stickiness to improve product quality. Besides, managers who focus on product quality should be cautious in adopting the product diversification strategy and be wary of the loss of product quality this strategy may cause.

Originality/value

This paper is the first study that has empirically validated the inverted U-shaped relationship between operational stickiness and product quality, and confirmed the moderating effect of product diversification on the relationship between operational stickiness and product quality. It provides a new idea to improve product quality by operational management.

Abstract

Purpose

Brand prominence describes the conspicuousness of a brand on a product. The purpose of this research is to investigate the types of brand prominence variation.

Design/methodology/approach

Utilizing an exploratory approach, 20 in-depth interviews were conducted where respondents created five outfits for anticipated social scenarios. The prominence of brands on these outfits were photographed, catalogued and qualitatively analyzed for thematic variation. Then, the brand prominence data points were quantitatively content analyzed.

Findings

The results from the qualitative analysis is an organizing framework describing three major types of brand prominence variation: brand visibility, brand frequency and brand distribution. In addition, heat maps were generated to visually display the prominence of brands distributed on the individual’s body. Subsequent results from the quantitative content analysis revealed that brands on shoes and pants were most likely to display significant levels of prominence in relation to frequency and visibility dimensions. Significant differences across participant demographic groups were also found in terms of the brand visibility.

Practical implications

This new information on brand prominence variation provides business brand managers with insight on how to measure and monitor their own levels of brand prominence displays. They, in turn, can engage in more strategic placement and prominence of their brands in the future production of fashionable clothes, shoes and accessories.

Originality/value

The conspicuous consumption literature has long been interested in studying how consumers display their brands. The current study demonstrates how consumer researchers can measure brand prominence variation and therefore gain better insight on the consumer who engages in conspicuous consumption via brand prominence variation.

Abstract

Purpose

This study aims to demonstrate the simultaneous effects between inventory leanness and product innovation, with market concentration being a moderator.

Design/methodology/approach

Using a large panel data collected from 3071 listed manufacturing enterprises from 2004 to 2021, this research employs a simultaneous system of equations via the three-stage least square method to explore the simultaneous relationship between inventory leanness and product innovation. In addition, the moderating role of market concentration is demonstrated via one four-model system.

Findings

As its core, inventory leanness positively impacts product innovation, while product innovation negatively affects inventory leanness. Moreover, there are differential impacts of the leanness of three inventory types on product innovation. Specifically, the inventory leanness of raw material negatively affects product innovation, while the inventory leanness of work-in-process and finished goods positively affect product innovation. Further, moderation analysis highlights that market concentration is a key moderator of this relationship.

Practical implications

Managers should carefully gauge the tradeoffs between inventory leanness and product innovation. Concretely, managers ought to consider the connections between inventory types and product innovation. In addition, managers are suggested to emphasis on market strategy.

Originality/value

This paper not only contributes to the current understanding of inventory leanness by verifying the impact of inventory leanness on product innovation but also investigates the simultaneous relationship between various inventory types and product innovation. Furthermore, it empirically demonstrates the moderating effect of market concentration on the relationship between inventory leanness and product innovation.

Abstract

Purpose

The purpose of this study is to demonstrate the nonlinear relationship between inventory stickiness and productivity, with investment efficiency being a mediator and environmental dynamism being a moderator.

Design/methodology/approach

Using a large panel data collected from 1,479 Chinese listed manufacturing enterprises over the period from 2010 to 2020, this research employs the instrumental variable method combined with two-stage least squares estimators to explore the inverted-U-shaped relationship between inventory stickiness and productivity. Furthermore, the mediating role of investment efficiency and the moderating role of environmental dynamism are demonstrated via two three-model systems.

Findings

As its core, productivity initially increases with inventory stickiness until a turning point at the end of the sample, beyond which the incremental effect of inventory stickiness on productivity become negative. That is, an inverted U-shaped relationship between inventory stickiness and productivity is found to exist. Moreover, further mediated moderation analysis highlights that investment efficiency is a key mediator of this relationship, whereas environmental dynamism is a key moderator.

Practical implications

Managers ought to gauge carefully against the tradeoffs between inventory stickiness and productivity. In general, over 90% of manufacturing enterprises have great potential to increase productivity by implementing sticky inventory management. In addition, managers are suggested to place emphasis on investment management and environmental strategy.

Originality/value

This paper contributes to the current understanding about productivity by illustrating and verifying the nonlinear effect of sticky inventory management. It may be the first study to empirically demonstrate the mediating effect of investment efficiency and the moderating effect of environmental dynamism on the relationship between inventory stickiness and productivity.

Abstract

Purpose

Although the adoption of lean inventory management for performance improvement has been widely recognized, sticky inventory management is still a stopgap measure for new small and medium enterprises (SMEs) against survival risks. The purpose of this paper is to demonstrate the nonlinear relationship between new SMEs inventory stickiness and venture survival by focusing on the moderating effects of environmental dynamism and financial constraints.

Design/methodology/approach

Classical moderating model is employed to investigate the effects of environmental dynamism and financial constraints on the relationship between inventory stickiness and venture survival. This study uses the accelerated failure time model for survival analysis and tests the relationships based on a large set of new manufacturing SMEs in China over the period from 1999 to 2007.

Findings

The main finding is that inventory stickiness has an inverted U-shaped impact on the likelihood of survival. However, the inflection point of this inverted U-shaped relationship lies at the end of the sample. Further moderation analysis indicates that environmental dynamism positively moderates the inverted U-shaped relationship between inventory stickiness and venture survival, while financial constraints negatively moderate this relationship.

Practical implications

Most new SMEs have great potential to increase the likelihood of survival by improving inventory stickiness before achieving effective lean inventory management. Sticky inventory management can help new SMEs achieve better survival in a dynamic environment. However, new SMEs that are financially constrained should prudently implement sticky inventory management.

Originality/value

This paper contributes to the existing understanding about the likelihood of SMEs survival by addressing the role of sticky inventory management. It may be the first study to empirically demonstrate the moderating effect of environmental dynamism and financial constraints on the inverted U-shaped relationship between inventory stickiness and venture survival.
