Abstract
Purpose
This paper aims to explore the effects of normative and hedonic motivations on continuous knowledge contribution, and how past contribution experience moderates the effects of the motivations on continuous knowledge contribution.
Design/methodology/approach
Based on goal-framing theory, the present study proposes a comprehensive theoretical model by integrating normative and hedonic motivations, past contribution experience and continuous knowledge contribution. The data for virtual community members' activities were collected using the Python Scrapy crawler. Logit regression was used to validate the integrative model.
Findings
The results show that both normative motivation (reflected by generalized reciprocity and social learning) and hedonic motivation (reflected by peer recognition and online attractiveness) are positively associated with continuous knowledge contribution. Moreover, these effects are found to be significantly influenced by members' past knowledge contribution experience. Specifically, the results suggest that past knowledge contribution experience undermines the influence of generalized reciprocity on continuous knowledge contribution but strengthens the effect of peer recognition and online attractiveness.
Originality/value
Although the emerging literature on continuous knowledge contribution mainly focuses on motivations as antecedents that promote continuous knowledge contribution, most of these studies assume that the relationship between motivating mechanisms and continuous knowledge contribution does not change over time. The study is one of the initial studies to examine whether and how the influence of multiple motivations evolves relative to levels of past contribution experience.

Abstract
Purpose
The purpose of this paper aims to investigate the effect of a model's eye gaze direction on the information processing behavior of consumers varying based on their gender.
Design/methodology/approach
An eye-tracking experiment and a memory test are conducted to test the research hypotheses.
Findings
Compared to an averted gaze, a model with a direct gaze attracts more attention to the model's face among male consumers, leading to deeper processing. However, the findings show that when a model displays a direct gaze rather than an averted gaze, female consumers pay more attention to the brand name, thus leading to deeper processing.
Originality/value
This study contributes to not only the existing eye gaze direction literature by integrating the facilitative effect of direct gaze and considering the moderating role of consumer gender on consumer information processing but also the literature concerning the selectivity hypothesis by providing evidence of gender differences in information processing. Moreover, this study offers practical insights to practitioners regarding how to design appealing webpages to satisfy consumers of different genders.

Abstract
Purpose
The purpose of this paper is to investigate the effects of political connections on the association between firms' business strategy and their tax aggressiveness in an emerging economy such as China.
Design/methodology/approach
The authors study a large sample of Chinese public firms from 2011 to 2017 using a panel regression model. In addition, a change analysis, an instrument variable test and alternative measures/samples are implemented as robustness tests.
Findings
Firms adopting innovative business strategy are more tax aggressive overall. However, innovative firms with political connections are less tax aggressive compared to those without political connections.
Originality/value
This paper contributes to the understanding of firms' tax behaviors in an emerging economy setting. It suggests that there are costs associated with political connections, such as foregone tax saving opportunities, which are understudies in the prior literature.

This paper aims to introduce a method to reduce corrosion caused by acidic-oxidized polymer degradant through subsection injection with different inhibitor.
Abstract
Purpose
This paper aims to introduce a method to reduce corrosion caused by acidic-oxidized polymer degradant through subsection injection with different inhibitor.
Design/methodology/approach
This paper introduced a method to reduce corrosion caused by acidic-oxidized polymer degradant through subsection injection with different inhibitor.
Findings
The experimental results indicated that the influence of pre-corrosion status on corrosion rate and effectiveness of corrosion inhibitor are significant. The corrosion inhibitors in both injection stage inhibited the corrosion process by preventing the contact of corrosive medium and steel surface through formation of a protective film on the surface of N80 steel. The corrosion rate of polymer degradant can be reduced to 0.63 g/m 2 h through subsection injection with different inhibitor.
Originality/value
This result will increase the production of polymer injection plugging wells through expanding the application of acidic-oxidized polymer degradant.

This paper aims to study the tribocorrosion behavior of 304 stainless steel (SS) sliding against SiC and Si3N4 counterparts in artificial seawater.
Abstract
Purpose
This paper aims to study the tribocorrosion behavior of 304 stainless steel (SS) sliding against SiC and Si3N4 counterparts in artificial seawater.
Design/methodology/approach
The tribocorrosion behavior of 304SS sliding against SiC and Si3N4 balls in artificial seawater has been investigated. The tests were conducted using a ball-on-disk rig equipped with an electrochemical workstation. The friction coefficient, surface morphology, wear volume and current density were determined.
Findings
When 304SS sliding against SiC ball, a smooth surface with a silica layer was formed on the top, which led to the low friction coefficient, current density and small wear volume. For 304SS-Si3N4 tribo-pair, a lot of metal debris was scattered on contact surfaces leading to high friction coefficient, current density and big wear volume.
Research limitations/implications
This research suggests that the lubrication effect of silicon-based ceramics is related to counterpart specimen in artificial seawater.
Practical implications
The results may help us to choose the appropriate ceramic ball under seawater environment.
Originality/value
The main originality of the work is to reveal the tribocorrosion behavior of 304SS sliding against SiC and Si3N4 balls, which help us to realize that the Si3N4 ball as water-lubricated ceramics could not exhibit lubrication effect when coupled with 304SS in artificial seawater.

Abstract
The objective of this research work is to study the artificial intelligence (AI)-based product benefits and problems of the agritech industry. The research variables were developed from the existing review of literature connecting to AI-based benefits and problems, and 90 samples of primary data from agritech industry managers were gathered using a survey of a well-structured research questionnaire. The statistical package of IBM-SPSS 21 was utilized to analyze the data using the statistical techniques of descriptive and inferential statistical analysis. Results show that better information for faster decision-making has been ranked as the topmost AI benefit. This implies that the executives of agritech units have a concern about the quality of decisions they make and resistance to change from employees and internal culture has been ranked as the topmost AI problem.

– The purpose of this paper is to investigate thermal properties at Cu/Al interfaces.
Abstract
Purpose
The purpose of this paper is to investigate thermal properties at Cu/Al interfaces.
Design/methodology/approach
A hybrid (molecular dynamics-interface stress element-finite element model (MD-ISE-FE) model is constructed to describe thermal behaviors at Cu/Al interfaces. The heat transfer simulation is performed after the non-ideal Cu/Al interface is constructed by diffusion bonding.
Findings
The simulation shows that the interfacial thermal resistance is decreasing with the increase of bonding temperature; while the interfacial region thickness and interfacial thermal conductivity are increasing with similar trends when the bonding temperature is increasing. It indicates that the higher bonding temperature can improve thermal properties of the interface structure.
Originality/value
The MD-ISE-FE model proposed in this paper is computationally efficient for interfacial heat transfer problems, and could be used in investigations of other interfacial behaviors of dissimilar materials. All these are helpful for the understanding of thermal properties of wire bonding interface structures. It implies that the MD-ISE-FE multiscale modeling approach would be a potential method for design and analysis of interfacial characteristics in micro/nano assembly.

Abstract
Purpose
The purpose of this paper is to investigate how managerial risk-taking incentives affect the sensitivity of R&D investments to the availability of a firm’s internal finance.
Design/methodology/approach
The author studies a large panel sample of US firms from 1992 to 2013 using a dynamic structural model and estimates a system GMM estimator that accounts for unobserved firm-specific effects, and that allows the author to address the potential endogeneity of all of the financial and executive compensation variables.
Findings
Managerial risk-taking incentives, in particular CEO portfolio vega, have a significantly positive impact on the financial constraints that bind R&D investments. Moreover, the author finds that CEO portfolio vega has stronger impacts on the investment-cash flow sensitivity of R&D in firms that are more likely to face binding financial constraints.
Originality/value
Prior studies on the financial constraints of R&D investments do not consider the potential impact of executive compensation on R&D investments. The author complements this stream of literature by providing novel results showing that managerial risk-taking incentives have a significant impact on the severity of the financial constraints on R&D investments.

Abstract
Purpose
A large-scale detection system with more data in short time bins, small dead space and small signal identification is the ideology the scientists pursuing. These proposed demands are able to be solved by 2.5 D integration. The substance of a 2.5 D integration is called silicon interposer, which consists of the through silicon via (TSV) and redistribution layer. However, the state-of-the-art silicon interposer is not able to sustain its own mechanical strength with the detector/readout array often sitting as standalone in large science facilities and fails to reduce the expansions on the installation of the components due to its insufficient thickness and size. This study aims to propose a moderation of current interposer with large-sized, standalone properties.
Design/methodology/approach
This paper proposes an interposer based on double-sided silicon vias (DSSVs) interconnection. Unlike conventional interposer that is interconnected by TSVs, DSSVs interposer is interconnected by top vias (T-vias) and bottom vias (B-vias).
Findings
The fabrication process of DSSVs interposer is introduced, and the superiority of the double-sided interconnection process with two etch-stop layers is described in detail. The impact of different T-vias depth on DSSVs interconnections in the same wafer is discussed and two times PI opening processes are proposed to eliminate air bubbles in the B-via. The relationship between the interposer thickness and warpage is studied by finite element analysis simulation and experiment. The prototype of the DSSVs interposer with a size of 100 × 100 mm and a thickness of 318.2 µm is fabricated, and electrical tests including short tests and continuity tests are carried out.
Originality/value
This paper proposes a large-sized and stand-alone interposer based on DSSVs interconnection.
