Abstract

Purpose

The purpose of this paper is to investigate the Lp‐maximal regularity for the abstract incomplete second order problem.

Design/methodology/approach

First, the paper gives the definition of the Lp‐maximal regularity for incomplete second‐order Cauchy problems and lists their basic properties based on Chill and Srivastava's recent work for completing second order problem. Second, the paper establishes its characterization by means of Fourier multiplier and the operator‐sum theorem. Finally, it considers an application to quasilinear systems by the regularity and linearization techniques.

Findings

Two criteria of Lp‐maximal regularity are obtained, and the existence of the local solution for the second order quasilinear problem is given. In addition, the connection on maximal regularity between second order problems with initial values and that with periodic problems is investigated. A perturbation result is given.

Originality/value

The maximal regularity is an important tool in the theory of non‐linear differential equations. The results obtained in this paper are universal because the operator is not necessarily the generator of a cosine operator function. Using this unifying approach it is possible to clarify the Lp‐maximal regularity and the existence of the solution for some systems described by partial differential equations, such as wave equations.

Abstract

Purpose

Based on self-consistency theory and conservation of resource theory, this study aims to discuss the impact of career calling congruence on employees’ innovation performance (IP) and analyzes the mediating effect of work passion [harmonious passion (HP) and obsessive passion (OP)].

Design/methodology/approach

To avoid serious common method biases, data in this paper were collected at three-wave. This paper investigated 381 employees to assess their career calling in time 1, measured their work passion in time 2 and assessed the IP of these employees in time 3. This paper also conducts confirmatory factor analysis, polynomial regression, response surface analysis, bootstrapping test and simple slope test to verify the research hypothesis in this paper.

Findings

In the career calling congruence case, employees’ HP, OP and IP are higher when both levels of serving oneself career calling and helping others career calling are high than when both are low; In the career calling incongruence case, employees’ HP, OP and IP are higher in the “low serving oneself and high helping others” case than in the “high serving oneself and low helping others” case; The more congruent the “serving oneself” and “helping others” career calling are, the higher the employees’ HP, OP and IP will be; and HP and OP mediate the relationship between career calling congruence and IP.

Originality/value

This study further clarifies the structure of career calling and find the positive effects of career calling on IP. The results present a deeper understanding of career calling and are universal applicable to the eastern culture context.

The purpose of this paper is to investigate how the pay gap between the management and ordinary employees influence corporate technology innovation.

Abstract

Purpose

The purpose of this paper is to investigate how the pay gap between the management and ordinary employees influence corporate technology innovation.

Design/methodology/approach

This study built a tournament model based on inventor innovation and career promotion. In addition, the authors use IV-GMM estimation method to address the possible endogeneity issue in the regressions.

Findings

Based on the unbalanced panel data of patents and pay gap in 1,501 Chinese listed manufacturing firms during 2001-2015, this paper finds that the pay gap could lead inventor innovation and improve technology innovation. The pay gap could encourage corporate innovation significantly: 1 percent increase in pay gap may increase the number of patents by 2 percent in the next year. The pay gap between the management and ordinary employees facilitates corporate innovation via two possible channels. First, inventor innovation and career promotion. Inventors are selected into the management mainly based on their innovation output. The larger the pay gap, the more innovation incentives and patents would gain. Second, investment increase in technology innovation. The pay gap and more patents that inventors gain would increase the ratio of inventors promoted to the management, who tend to pour more resources into R&D activities and absorb more inventors to the management due to their sectionalism and R&D preference. The above two channels constitute a positive feedback mechanism among technology innovation, inventor promotion and increase in R&D investment.

Research limitations/implications

This paper highlights that pay gap between the management and ordinary employees is an important issue that could encourage corporate innovation. The conclusions imply that pay gap could encourage inventors to work hard and produce more patents, which could help them to enter into the management such as executives or directors.

Originality/value

This study contributes to the current literature by implying that pay gap could have positive effects on innovation through theoretical and empirical analysis. Also, this study finds that inventor promotion due to the pay gap is a critical channel to stimulate corporate technology innovation.

Abstract

Purpose

Risk perception is an essential factor affecting how individuals evaluate risk, make decisions and behave. The impact of risk perception on customer purchase behavior has been widely studied; however, the association has been debated. Therefore, the purpose of this paper is to examine the relationship between risk perception and customer purchase behavior and to examine factors that could moderate it.

Design/methodology/approach

This study conducted a meta-analysis of this relationship and examined factors that could moderate it. Six databases were comprehensively searched. Two reviewers independently selected the studies for inclusion, extracted data and assessed quality. Pearson's r was used as the effect estimate. A total of 33 studies were included in the meta-analysis.

Findings

The results revealed a negative relationship between risk perception and customer purchase behavior. The geographical region, purchase channel and country development level affected the relationship. The correlation between perceived risk and purchase behavior in European consumers was the highest, followed by the correlation in American consumers; the weakest correlation was found in Asian consumers. For consumers in developed countries, perceived risk had a stronger negative influence on customer purchase behavior than that for consumers in developing countries. The perceived risk of online purchase channels had a stronger negative impact on customer purchase behavior than that of offline purchase channels.

Research limitations/implications

Risk perception is a useful context in which to explain barriers to customer purchase behavior. In addition, reducing consumers’ risk perception and perfecting the market transaction process with respect to buying behavior should be further studied.

Originality/value

The findings of this review indicate a direct negative relationship between risk perception and customer purchase behavior. To the best of the authors’ knowledge, this review is the first to meta-analytically summarize the impact of risk perception on customer purchase behavior in social sciences research, and it also illuminates new perspectives for future studies.
