The purpose of this study is to improve the thermal management of lithium-ion batteries. The phase change material (PCM) cooling does not require additional equipment to consume energy. To improve the heat dissipation capacity of batteries, fins are added in the PCM to enhance the heat transfer process.

Computational fluid dynamics method is used to study the influence of number of vertical fins and ring fins (i.e. 2, 4, 6 and 8 vertical fins, and 2, 3, 4 and 5 ring fins) and the combination of them on the cooling performance.

The battery maximum temperature can be decreased by the PCM with vertical or ring fins, and it can be further decreased by the combination of them. The PCM with eight vertical fins and five ring fins reduces the battery maximum temperature by 5.21 K. In addition, the temperature and liquid-phase distributions of the battery and PCM are affected by the design of the cooling system.

This work can provide guidelines for the development of new and efficient PCM cooling systems for lithium-ion batteries.

The combination of PCM and fins can be used to reduce the battery maximum temperature and temperature difference.

The purpose of this study is to design a new type of cold plate to improve the thermal performance of liquid-cooled thermal management system of lithium-ion batteries.

A cold plate with leaf type channels is proposed to enhance the cooling performance. Effects of the leaf type channel parameters (i.e. channel angle 20°, 40°, 60°, 80°; coolant mass flow rate 0.25 × 10^–3, 0.50 × 10^–3, 0.75 × 10^–3, 1.00 × 10^–3, 1.25 × 10^–3 kg·s⁻¹; channel number 1, 3, 5, 7) on the performance are numerically investigated by using a 3D mathematical model.

Compared to the traditional I type channels, the leaf type channels have better cooling performance. It is found that the battery temperature variation and channel pressure drop are decreased with decreasing channel angle and increasing channel number. In addition, the cooling performance can be improved by increasing the coolant mass flow rate.

This study can provide guidance for the development of novel effective cold plates.

The design of cold plates with leaf type channels can be used in liquid-cooled thermal management system to reduce the battery temperature difference.

Two types of institutional constraints, namely, institutional voids and policy uncertainty, have been recognised and elaborated, including their influence on new venture performance. However, not enough attention has been paid to the multidimensional attribute of institutional transformation. By hinting at a relatively underexplored third type of institutional constraints, i.e. institutional fragility, this paper aims to build a comprehensive framework of institutional constraints to analyse how innovative start-up performance is influenced by institutional constraints.

Using Chinese manufacturing firms as the empirical sample, the authors use an econometric method to test the relationship between institutional constraints and the performance of innovative start-ups.

On the basis of a uniquely constructed database from 2005 to 2007, the authors find that institutional constraints are negatively associated with innovative start-up performance proxied by return on assets, sales growth and new product sales.

The study offers researchers and practitioners a detailed view of institutional constraints and innovative start-up performance.

The advancements of mobile technologies and devices have greatly facilitated the extension of online services from web to mobile environments. Drawing on the categorization theory, the purpose of this paper is to explore the impact of perceived entitativity on users’ web-mobile service extension behavior. The research model considers how perceived entitativity serves as a category cue to link the category- and piecemeal-based processing and shape users’ adoption of extended mobile services.

An online survey (n=552) was conducted to empirically test the model. The data were analyzed by structural equation modeling approach.

The results offer two major findings. First, performance expectancy, perceived controllability and subjective norm are important antecedents of users’ usage intention. Second, perceived entitativity has three types of effects on usage intention: it exerts a direct and positive influence on usage intention; it indirectly facilitates usage intention through increasing PE and perceived controllability; and it moderates the relationship between subjective norm and usage intention.

This study contributes to the literature by taking into account the interplay of category- and piecemeal-based processing to understand consumers’ web-mobile service extension behavior.

Extant literature has indicated that government support is one of the main drivers of international expansion of Chinese multinational enterprises. However, research on the influence of governors on firm internationalization is still limited. Drawing upon the institution-based view, we theorize a novel concept of institutional enablement to illustrate the influence of a governor's pro-market ideology on Chinese firms' internationalization.

We analyze the relationship between a governor's pro-market ideology (consisting of a pro-market political ideology, an overseas educational background and a business background) and firm internationalization with a sample of Chinese public companies during 2014–2017.

We find a direct and positive effect of a governor's pro-market ideology on firm internationalization. We also find an indirect and positive effect of a governor's pro-market ideology through regional, inward foreign direct investment.

To the best of our knowledge, this paper is the first to investigate an underexplored question of the impact of governors on firm internationalization and to develop a novel concept of institutional enablement, based on discursive institutionalism.

Most previous research assumes that the outward foreign direct investment (OFDI) decisions of multinational corporations (MNCs) are made independently of the actions or characteristics of their peers. Therefore, the important influence of peer effects on the OFDI strategy is often neglected. The purpose of this paper is to identify two broad categories of peer effects, i.e. learning-based and profit-driven imitations and examine the important influence of peer effects on MNCs’ internationalization strategy.

Using Chinese manufacturing firms as the empirical sample, the authors employ an econometric method (logit regression) to test the relationship between peer effects and an internationalization strategy.

Learning-based and profit-driven imitations are positively associated with a focal MNC’s OFDI decision. Policy uncertainty also positively moderates the relationship between peer effects and the OFDI strategy. Moreover, both peer effects are amplified when a firm is equipped with a dense export network.

The study offers researchers and practitioners a detailed view of interorganizational imitation behavior in terms of an internationalization strategy.

The emergence and rapid expansion of global value chains (GVCs) have profoundly changed and reshaped the global trade regime. Although many determinants of GVC participation of enterprises have been discussed extensively in extant literature, the important influence of local institutional profile on GVC participation is often neglected. The purpose of this paper is to investigate the influence of local institutional profile on GVC participation.

Taking the World Bank Enterprise Survey as the empirical sample, it is used an econometric method (propensity score matching technique) to test the relationship between local institutional profile and GVC participation.

Local institutional quality is positively related to GVC participation. Moreover, GVC participants display better innovation performance than non-participants. Innovation benefit from GVC participation is contingent upon the abilities of the participants, namely, absorptive capacity and research and development collaboration experience. GVC participants who only either export or import is compared with those who export and import; the findings show that the latter benefits more than the former.

This study offers researchers and practitioners a detailed view of local institutional profile and GVC participation.

Drawing from the spillover effect literature, the purpose of this paper is to investigate the spillover effect in consumers’ web-mobile payment extension behavior. The authors figure out two categories of factors associated with the spillover effect: relevant schema and schematic fit. Cognitive trust and emotional trust in web payment are used to capture relevant schema, while perceived similarity and perceived business tie are proposed to denote schematic fit in the web-mobile payment extension context.

An online survey (n =552) was conducted to empirically test the model. The data were analyzed by structural equation modeling approach.

The results show that relevant schema and schematic fit factors positively influence perceived value of mobile payment (MP), which facilitates consumers’ behavioral intention of MP.

This study contributes to the extant literature by theoretically identifying the key factors of the spillover effect and empirically investigating its role during the web-mobile service extension process.

Drawing on the social learning theory, the purpose of this paper is to examine the antecedents and consequences of users’ excessive online social gaming. Specifically, the authors develop a model to propose that observational learning and reinforcement learning mechanisms together determine excessive online social gaming, which further foster adverse consequences.

The model is empirically validated by a longitudinal survey among users of a popular online social game: Arena of Valor. The empirical data are analyzed using component-based structural equation modeling approach.

The empirical results offer two key findings. First, excessive online social gaming is determined by observational learning factors, i.e. social frequency and social norm, and reinforcement learning factors, i.e. perceived enjoyment and perceived escapism. Second, excessive online social gaming leads to three categories of adverse consequences: technology-family conflict, technology-work conflict and technology-person conflict. Meanwhile, technology-family conflict and technology-work conflict further foster technology-person conflict.

This study contributes to the literature by developing a nomological framework of excessive online social gaming and by extending the social learning theory to excessive technology use.
