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 small dimensions of future device designs also imply a stronger effect of material boundary resistance. For nanoscale devices and structures, especially, interface phenomena often dominate their overall thermal behavior. The purpose of this paper is to propose molecular dynamics (MD) simulations to investigate the mechanical and thermal properties at Cu‐Al interface.

Design/methodology/approach

The two‐temperature model (TTM)‐MD model is used to describe the electron‐phonon scattering at interface of different metals. Before the simulation of heat transfer process, a non‐ideal Cu‐Al interface is constructed by simulating diffusion bonding.

Findings

According to the simulation results, in unsteady state, the temperature distribution and the displacements of atoms near the interface tend to generate stress and voids. It reveals the damage mechanics at the interface in heat transfer.

Originality/value

The atomic model proposed in this paper is computationally efficient for interfacial heat transfer problems, and could be used for investigation of other interfacial behaviors of dissimilar materials.

Abstract

Purpose

This study aims to investigate the causal relationships within an experimental culture of improvisation capability and firm performance, following the logic of “culture-capability-performance” and building on informal institution theory and dynamic capability theory.

Design/methodology/approach

Data was mainly collected via on-site questionnaires from firm managers, and 196 valid questionnaires were analyzed using structural equation modeling to test the relationship among experimental culture, improvisation capability and firms’ performance.

Findings

Trust and support had a positive impact on firm spontaneity, while the effect of action promotion and error tolerance was not significant. Action promotion, trust and support demonstrate substantial positive effects on the creativity of a firm. Both dimensions of improvisation capability positively and significantly influence a firm’s performance.

Research limitations/implications

The research respondents were firm managers. Cross-sectional data were used to analyze the model, which may cause common method variance. The research context was limited to China, and the generalizability of the results needs to be considered.

Practical implications

Firms can cultivate a culture of trust and support to enhance their spontaneity and improvisation capability. They can encourage cross-departmental communication, empower employees with autonomy in decision-making, provide appropriate resource support for employees’ decisions and use praise and reward incentives to spur further innovation achievements.

Originality/value

This study addresses the gaps in a firm’s improvisation capability within a Chinese market context by theoretically and empirically examining the role of experimental culture and assessing the relationship among each of the dimensions of improvisation capability in relation to firm performance identified in this study.

Abstract

Purpose

Recent studies in the accounting literature have investigated the economic consequences of R&D capitalization. Discretionary R&D capitalization for target beating can be characterized as a firm signaling private information on its future economic benefits or as opportunistic earnings management. R&D capitalization also has an impact on a firm’s marginal costs and product market competition. The purpose of this paper is to address how firms choose R&D levels for the purpose of meeting or beating their earnings targets and how this influences sequential product market competition.

Design/methodology/approach

The authors study this issue in a stylized game-theoretic model where R&D choices of a firm are not only strategically made but also used to convey proprietary information to its rival. The model provides a rationale for a firm distorting its R&D level to earn more profits and meet its earnings target.

Findings

The equilibrium result indicates that before the realization of common cost shock, a firm can influence the output of its accounting system (i.e. meeting an earnings target) through adjusting its R&D choices. This firm will overinvest in R&D, and this will give an opportunity to create some reserves to be used later to earn a higher profit and reach the earnings target.

Originality/value

This paper contributes to the research on real earnings management in terms of how R&D capitalization affects a firm’s R&D choices by influencing the output of its accounting system through adjusting its R&D choices and the strategic impact of those choices.

Abstract

Purpose

The purpose of this study is to compare the communication practices of Chinese and US companies on YouTube and explores the effectiveness of different communication strategies at the topic level.

Design/methodology/approach

The author selected 22 Chinese companies and 22 US firms and compared the content of their English language corporate YouTube channels through content analysis, sentiment analysis and cluster analysis.

Findings

The results revealed that the three communication strategies (information, response and involvement) in general were not significantly different regarding their engagement rates, but they generated different comment scores when communicating topics of corporate social responsibility. The results also showed that Chinese companies were more likely than American firms to display the speeches of corporate leaders, use collectivistic references and present human interest messages in YouTube videos.

Research limitations/implications

This study sheds light on how national institutional environment shapes corporate communication on YouTube.

Practical implications

This study challenges the infatuation with the involvement strategy and offers some advice for practitioners on topic selection and user comment function management.

Originality/value

This study makes a novel contribution to the literature of corporate communication on YouTube by adopting a cross-national comparative approach. A conceptual framework of major factors influencing stakeholder responses on YouTube was presented.

Abstract

Purpose

Built asset management processes require a long transition period to collect, edit and update asset conditions information from existing data sets. This paper aims to explore and explain whether and how digital technologies, including asset information model (AIM), Internet of Things (IoT) and blockchain, can enhance asset conditions assessment and lead to better asset management.

Design/methodology/approach

Mixed methods are applied to achieve the research objective with a focus in universities. The questionnaire aims to test whether the integration of AIM, IoT and blockchain can enhance asset condition assessment (ACA). Descriptive statistical analysis was applied to the quantitative data. The mean, median, mode, standard deviation, variance, skewness and range of the data group were calculated. Semi-structured interviews were designed to answer how the integration of AIM, IoT and blockchain can enhance the ACA. Quantitative data was analysed to define and explain the essential factors for each sub-hypothesis. Meanwhile, to strengthen the evaluation of the research hypothesis, the researcher also obtained secondary data from the literature review.

Findings

The research shows that the integration of AIM, IoT and blockchain strongly influences asset conditions assessment. The integration of AIM, IoT and blockchain can improve the asset monitoring and diagnostics through its life cycle and in different aspects, including financial, physical, functional and sustainability. Moreover, the integration of AIM, IoT and blockchain can enhance cross-functional collaboration to avoid misunderstandings, various barriers and enhance trust, communication and collaboration between the team members. Finally, costs and risk could be reduced, and performance could be increased during the ACA.

Practical implications

The contribution of this study indicated that the integration of AIM, IoT and blockchain application in asset assessment could increase the efficiency, accuracy, stability and flexibility of asset assessment to ensure the reliability of assets and lead to a high-efficiency working environment. More importantly, a key performance indicator for ACA based on the asset information, technology and people experience could be developed gradually.

Originality/value

This study can break the gap between transdisciplinary knowledge to improve the integration of people, technology (AIM, IoT and blockchain) and process value-based ACA in built asset management within universities.

Abstract

Purpose

Inspired by the dynamic changes in our daily lives enabled via quantified-self technologies and the urgent need for more studies on the human-computer interaction design mechanisms adopted by these applications, this study explores the value of user affective experience mirroring and examines the empowerment effect of meaningful gamification in a psychological self-help system (PSS) that aids people in work stress relief.

Design/methodology/approach

Based on an analysis of the existing systems and theories in relevant fields, we conducted mixed-method research, involving semi-structured interviews, experience sampling experiments and user bio data triangulations, to identify the benefits of user affective experience mirroring and examine the impact of visual impact metaphor–based (VIM) meaningful gamification on PSS users.

Findings

For a gamified PSS, users generally perceive VIM as arousing more feelings of enjoyment, empathy, trust and usefulness, empowering them to gain more mastery and control over their emotional well-beings, especially with relieving their occupational stress and upbringing their level of perceived happiness. Overtime, VIM-based meaningful gamification further boosts such value of a PSS.

Research limitations/implications

Weaving together meaningful gamification and psychological empowerment theories, the results emphasized that successful empowerment of user through gamification in PSSs relies heavily on whether a deeper and meaningful affective connection can be established with the users, in short, “meaningful gamification for psychological empowerment”. Such an understanding, as demonstrated in our research framework, also sheds light on the design theories for persuasive technology and human influence tactics during human computer interactions.

Practical implications

The results of the study demonstrate to practitioners how to make the best use of gamification strategies to deeply relate to and resonate with users. Even without complicated game-play design, meaningful gamification mechanisms, such as VIM facilitate the empowerment of users while gaining their appreciation, establishing a deeper connection with them and eventually generating persuasive effects on intended future behavioural outcomes.

Social implications

The effective management of work-related stress with handy tools such as a VIM-based PSS can be beneficial for many organizations and, to a large extent, the society.

Originality/value

This study proposed and empirically demonstrated the empowerment effect of meaningful gamification for PSS users. In this cross-disciplinary study, theories from different research domains were synthesized to develop a more thorough and multi-faceted understanding of the optimal design strategies for emerging information systems like this VIM-based PSS.

Abstract

Purpose

During the coronavirus disease 2019 (COVID-19) pandemic, ubiquitous social media has become a primary channel for information dissemination, social interactions and recreational activities. However, it remains unclear how social media usage influences nonpharmaceutical preventive behavior of individuals in response to the pandemic. This paper aims to explore the impacts of social media on COVID-19 preventive behaviors based on the theoretical lens of empowerment.

Design/methodology/approach

In this paper, survey data has been collected from 739 social media users in China to conduct structural equation modeling (SEM) analysis.

Findings

The results indicate that social media empowers individuals in terms of knowledge seeking, knowledge sharing, socializing and entertainment to promote preventive behaviors at the individual level by increasing each person's perception of collective efficacy and social cohesion. Meanwhile, social cohesion negatively impacts the relationship between collective efficacy and individual preventive behavior.

Originality/value

This study provides insights regarding the role of social media in crisis response and examines the role of collective beliefs in the influencing mechanism of social media. The results presented herein can be used to guide government agencies seeking to control the COVID-19 pandemic.

Abstract

Purpose

While the significance of organizational resources and capabilities is widely discussed, little is known about their interrelationships as well as benefits for firms that are involved in coopetitive relationships. Against this backdrop, the purpose of this paper is to investigate the performance effects of entrepreneurial orientation, strategic intent and potential absorptive capacity as well as their complementarity effects on operational and innovation performance for firms involved in horizontal coopetitive relationships.

Design/methodology/approach

Drawing upon the resource-based-view, dynamic capabilities and the relational view theories, this study forwards numerous hypotheses between the constructs of interest. The proposed hypotheses are tested utilizing survey data collected from 313 horizontal coopetitive relationships.

Findings

The results clearly suggest that entrepreneurial orientation, strategic intent and potential absorptive capacity could positively impact innovation and operational performance outcomes independently. In addition, the authors also find strategic intent and potential absorptive capacity to have differential moderating effects on the relationships between entrepreneurial orientation and the performance outcomes.

Originality/value

The findings suggest that although strategic intent and potential absorptive capacity could lead to performance benefits independently, when it comes to coopetitive relationships, the use of both these capabilities may not substantially increase the positive impact of entrepreneurial orientation on performance outcomes. Specifically, given that these capabilities could intensify competitiveness as well as hostility between partners, they seem to affect the firm's performance differently.

Abstract

Purpose

This study aims to examine the impact of five consumption values (i.e. ecological, functional, symbolic, experiential and epistemic) on consumers’ intentions to adopt green products. Using Thaler’s utility theory, the authors investigate the indirect effect of values on purchase intention through acquisition utility and transaction utility. Two moderators (materialism orientation and value consciousness) further influence the strength of the effect of consumption values on transaction utility.

Design/methodology/approach

The authors used a survey design (N = 437 Chinese customers recruited through a Chinese online panel provider) and structural equation modeling (SEM) to test six hypothesized relationships in the proposed model. Moderated SEM was used for moderation analysis.

Findings

Most hypothesized relationships in the model were confirmed, with the exception of the functional value–transaction utility link and the moderating effect of materialism on the experiential value–transaction utility relationship.

Research limitations/implications

Larger-scale research may help to determine whether there are more significant differences in consumer evaluations of different types of green products.

Practical implications

As the concept of green marketing in China evolves, firms should continue to stress the importance and value of green products regarding individuals’ care for the environment, status and self-image. Further, firms should conduct systematic utility analyses and address acquisition and price equity in a strategic process.

Originality/value

To the best of the authors’ knowledge, this study is the first to adapt utility theory to green consumption and proposes a clearly defined and well-substantiated set of utility types by merging economic and green consumption literature.
