Abstract

Purpose

This study aims to advance and test a multi-dimensional operationalization of absorptive capacity (ACAP) to ascertain its mediating role in the transformation of R&D expenses in actual performance.

Design/methodology/approach

This study departs from the conceptualization of ACAP as a reflective higher-order R&D-based construct, by specifying ACAP into its components and using an operationalization that encompasses both R&D and non-R&D measures to perform mediation analysis on a sample of 1,096 Chinese mainland firms.

Findings

This study's findings report evidence of positive but different roles of the components of ACAP, with specific reference to the positive but partial mediating role of realized ACAP between both R&D expenses and potential ACAP on a firm’s performance. Relevant research and practical implications for both management and policymaking are discussed.

Originality/value

The approach to ACAP conceptualization and measurement taken in this study provides empirical support to an often assumed and, incidentally, under-explored relationship. Moreover, it contributes with a multi-dimensional, non-exclusively R&D-based and process-oriented perspective to the analysis of the role played by ACAP in Chinese firms’ R&D effectiveness.

Abstract

Purpose

Technological entrepreneurship concerns the transformation of potentially viable technological opportunities into successful businesses. Absorptive capacity is argued to be essential for this transformation, since it can facilitate the prediction of new technology trends and the assimilation and application of new knowledge to produce new commercial outputs. The investigation of the relationships between absorptive capacity, technological entrepreneurship and their impact on Guangdong technology firms' performance is the purpose of this study.

Design/methodology/approach

In this aim a positive causal chain from absorptive capacity to technological entrepreneurship and from this latter to performance is tested through a mediation analysis, which uses an ordinary least squares regression‐based path analytical framework for estimating indirect effects on a sample of 113 Guangdong technology‐based firms.

Findings

Findings are consistent with the hypothesis that greater absorptive capacity leads to greater technological entrepreneurship, which in turn leads to greater performance. Therefore evidence is provided about both the mediating role of technological entrepreneurship and the role of absorptive capacity as its antecedent in relation to Guangdong‐based technology firms' performance.

Originality/value

A relevant but somewhat neglected relationship is examined using an integrative model in the Guangdong context. Moreover the study uses direct measures of absorptive capacity as a capability and provides a firm‐level operationalization of technological entrepreneurship. In so doing it also adopts state‐of‐the‐art analysis techniques and highlights the relevance of investments in soft factors for Guangdong technology firms' path towards excellence.

Abstract

Purpose

The purpose of this paper is to explore the legitimacy needs and legitimation strategies of Internet start-ups in the context of industry dynamism.

Design/methodology/approach

The purpose of this paper is to explore the legitimacy needs and legitimation strategies of Internet start-ups in the context of industry dynamism.

Findings

The authors found that Internet start-ups are in great need of acquiring market and relational legitimacy at their nascent stages. Conformance to the environment is widely adopted by them as a legitimacy-enhancing strategy. There is an inverted “U” relationship between the maturity of the industry and the proactivity of any legitimation strategy in the sector. In the face of high- and low-level industry maturity, start-ups tend to employ prudent strategies to build up legitimacy. While in medium-mature industries, ventures are more likely to adopt proactive and aggressive strategies.

Research limitations/implications

Due to the very nature of case methodology, this study is based on a small number of observations and it is set in the context of the Internet industry. The generalizability of its findings needs to be reinforced by further concrete studies.

Practical implications

This paper suggests that industry dynamism should be taken into account carefully when implementing a choice of legitimation strategies.

Originality/value

This study makes an attempt to further our understanding of how industry dynamism influences firms’ choices of legitimation strategies.

Abstract

Purpose

The purpose of this paper is to present a new method and model for determining the optimal decision-making for the pricing strategy to the Fuji apple in Shaanxi of Chain which is representing fresh agricultural products under the e-commerce environment.

Design/methodology/approach

Considering the rapid development of information technology as well as internet that actually motivate the e-commerce, Fuji apple is a distinctive product in China’s Shaanxi; its sales channels have extended to online sales under the wave of e-commerce. Internet trading platforms make it possible to trade online in real time between suppliers and customers who live in different geographical areas. In this paper, the authors study how to price online to maximize the total revenue. The challenge is to optimally price two different qualities of apple. Based on the consumer surplus theory, the authors use the method that builds the function of the relationship between the proportion of consumers purchasing different qualities of products and price.

Findings

This paper presents a generalized model to determine the optimal pricing that maximizes the total revenue of a fruit grower over a finite planning horizon. The authors divided discount into two intervals and discussed the optimal discounting and pricing at both intervals. Then they determined the optimal pricing strategy for Fuji apple in Shaanxi of Chain under the e-commerce environment.

Originality/value

This paper makes up for the lack of existing studies of pricing under the e-commerce environment. A new method and approach to the traditional pricing strategy is established and applied to a management decision-making problem with Chinese characteristics in reality.

Abstract

Purpose

The purpose of this paper is to develop a build strategy for inclined thin-walled parts by exploiting the inherent overhanging capability of the cold metal transfer (CMT) process, which release wire-arc additive manufacturing from tedious programming work and restriction of producible size of parts.

Design/methodology/approach

Inclined thin-walled parts were fabricated with vertically placed welding torch free from any auxiliary equipment. The inclined features were defined and analyzed based on the geometrical model of inclined parts. A statistical prediction model was developed to describe the dependence of inclined geometrical features on process variables. Based on these models, a build strategy was proposed to plan tool path and output process parameters. After that, the flow work was illustrated by fabricating a vase part.

Findings

The formation mechanism and regulation of inclined geometrical features were revealed by conducting experimental trials. The inclined angle can be significantly increased along with the travel speed and offset distance, whereas the wall width is mainly dependent on the ratio of wire feed speed to travel speed. In contrast to other welding process, CMT has a stronger overhanging capability, which provides the possibility to fabricate parts with large overhanging features directly with high forming accuracy.

Originality/value

This paper describes a novel build strategy for inclined thin-walled parts free from any auxiliary equipment. With the proposed strategy, a complex structural component can be deposited directly in the rectangular coordinates additive manufacturing system, indicating infinite possibilities on the producible size of the parts. Moreover, equipment requirements and tedious program work can also be significantly reduced.

The purpose of this paper is to focus on determining the optimal sales price for non-instantaneous deterioration items according to consideration of freshness and demand.

Abstract

Purpose

The purpose of this paper is to focus on determining the optimal sales price for non-instantaneous deterioration items according to consideration of freshness and demand.

Design/methodology/approach

In this model, the authors have described the demand function which is dependent on price as well time. The products that the deterioration is considered as non-instantaneous have a determinate shelf life, and their demand rate will decrease over time after the beginning of the selling period. This paper depicts that the total profit of non-instantaneous deterioration items using the dynamic pricing strategy is higher than that using fixed pricing strategy.

Findings

Finally, to illustrate and validate the model, the authors have used some numerical examples. A new freshness function and the model to study pricing policy are developed as well applied to solve managerial decision problems.

Originality/value

This paper complements the lack of the existing theoretical research of pricing for non-instantaneous deterioration items under an e-commerce environment. A new freshness function and the model to study pricing policy are developed as well applied to solve managerial decision problems.

Abstract

Purpose

As a good absorbing material candidate, a functionally graded wave absorber can be tailored to satisfy the impedance match principle by gradually changing material property. The paper aims to discuss these issues.

Design/methodology/approach

The electromagnetic wave absorption properties are discussed. An analysis model is proposed to provide an insight into its mechanical characteristics during wave absorption. Considering the energy-converting and thermal deformation properties, the thermoelastic behaviors of an absorber are analyzed by numerical method. The effects of material and geometrical properties are discussed in detail.

Findings

The results demonstrate that absorbing effect of graded composite is enhanced. Good performance of low reflectance and high absorption with gentle thermal stress distribution can be obtained by proper designing of the gradient absorber.

Originality/value

Functionally graded materials exhibit a progressive compositional gradient change along certain dimension of structures, which can be used as absorbing materials for the gradual change of material property tailored to satisfy the principle of impedance match. The design of functionally graded absorbing materials usually should consider not only the electromagnetic performance, but also the mechanical properties simultaneously. Therefore, few investigations have addressed the mechanical characteristics of absorbers. This paper presents some studies on the electromagnetic, especially mechanical behaviors during electromagnetic wave absorption. It is helpful to provide mechanical reference for designing an absorber.

Abstract

Purpose

The purpose of this paper is to examine the relationship between political connections and corporate tax aggressiveness in Malaysia. In addition, this paper investigates the relationship between corporate governance variables and corporate tax aggressiveness. Next, the study investigates the mitigating role of corporate governance in the relationship between political connections and corporate tax aggressiveness.

Design/methodology/approach

The sample of this study is based on 2,538 firm-year observations during the 2000-2009 periods. This study employs a panel least square regression with both period and industry fixed effects. The study retrieved the corporate governance variables from the downloaded annual reports, whilst the remaining data were collected from Compustat Global.

Findings

This study finds that politically connected firms are more tax aggressive than non-connected firms. Furthermore, the study finds that large board size decreases the likelihood of tax aggressiveness and a non-linear relationship exists between institutional ownership and tax aggressiveness suggesting increase in monitoring as the ownership increases. However, the study finds no evidence to suggest that corporate governance mitigates the influence of political connections in promoting tax aggressiveness behavior. The findings suggest that the impact of political connections could outweigh the benefits of changes in corporate governance in Malaysia.

Research limitations/implications

The data are not recent, but it reflects a rather longitudinal research period.

Originality/value

This paper extends the literature of tax research in Malaysia which is in its’ infancy stage. Furthermore, it investigates the role of political connections in tax-planning research.

In this work, a true random number generator is designed by sampling the double-scroll analog continuous-time chaotic circuit signals.

Abstract

Purpose

In this work, a true random number generator is designed by sampling the double-scroll analog continuous-time chaotic circuit signals.

Methodology

A Chua circuit based on memristance simulator is designed to obtain a non-linear term for a chaotic dynamic system. It is implemented on the board by using commercially available integrated circuits and passive elements. A low precision ADC which is commonly found in the market is used to sample the chaotic signals. The mathematical analysis of the chaotic circuit is verified by experimental results.

Originality

It is aimed to be one of the pioneering studies (including low precision ADC) in the literature on the implementation of memristive chaotic random number generators.

Findings

Two new methods are proposed for post-processing and creating random bit array using XOR operator and J-K flip flop. The bit stream obtained by a full-hardware implementation successfully passed the NIST-800-22 test. In this respect, the availability of the memristance simulator circuit, memristive chaotic double-scroll attractor, proposed random bit algorithm and the randomness of the memristive analog continuous-time chaotic true number generator were also verified.
