The purpose of this paper is to show these effects in an abstracted micro gap test bench. Because of stronger emission laws, the ambition to raise the rail pressure in common-rail systems from the current 2500 bar to 3000 bar is a given. The pressure increase will allow fine atomization of fuel and therefore more efficient combustion. But within the technical system of the high-pressure pump, stronger thermal stresses of the piston–cylinder contact are expected. A pressure drop from such a high level causes high temperature gradients due to energy dissipation.

For a detailed examination, the critical piston–cylinder contact has been investigated in an abstracted test bench with a flat parallel gap and an equivalent thermo-elastohydrodynamic simulation model.

The simulation results show good accordance to the measurements of pressures, temperatures and leakages for pressures up to 3000 bar. Comparison with elastohydrodynamic lubrication results outlines the need to consider temperature and pressure effects viscosity and solid deformation for the simulation and design of tribological contacts at high pressures.

This paper describes a simulation method with high accuracy to investigate tribological contacts considering temperature effects on solid structures and the fluid film. The thermo-elastohydrodynamic lubrication simulation method is valid not only for piston–cylinder contacts in high-pressure pumps but also for journal bearings in combustion engines.

This study investigates the effect of product quality and price fairness on consumer cause-related marketing (CRM) participation and also the moderating role of donation-related customer predispositions (i.e. empathy and cause importance) on this relationship.

Data for the study were obtained from 240 respondents. A structural equation modelling approach was used in analysing the data.

Results from the analysis indicate that fair pricing and product quality affect CRM participation. The findings also provide insights into the moderation role of empathy and cause importance.

Prior research studied the effect of promotion on CRM participation; however, this study examines the effect of product and price. The findings offer insight into issues of research and managerial interest, offering insightful implications to the academic and practitioner communities in developing countries, respectively.

This paper aims to identify the most influential papers/authors, publication outlets and theoretical and empirical research topics of the international new venture (INV) literature.

The authors examine the intellectual structure of the INV literature using bibliometric citation and co-citation analysis. The authors focus on the 100 most cited papers in this research stream published between 1994 and 2015. In the post-hoc reading, they supplement their main bibliometric techniques with the content analysis method to shed light on some issues.

The authors find that the literature has grown significantly over the past two decades, increasing its relevancy in the academic discourse. The findings show the interdisciplinary nature of the INV literature, where we can find different research topics: Definition of INVs, measurements of “newness” and “degree of internationalization” and the characteristics of international entrepreneurs; time dimension in terms of speed of internationalization; international versus domestic new ventures; and the relationships between firm-specific advantages, international strategy and INV performance.

The authors identify the most influential studies and authors in the INV discipline and show its evolution from the very start to the present. They present the key topics in the literature and highlight the theoretical debates and the inconsistencies between theoretical conceptualization and measurements in the empirical work. The authors offer suggestions for promising future research directions and identify the major conceptual framework on which future research can be constructed. Overall, this study contributes to enhance the understanding of the INV phenomenon and provides useful new insights.

The purpose of this paper is to explore maintenance strategies for manufacturing equipment in Chinese firms.

Data were collected from Chinese companies using a questionnaire administered during face‐to‐face interviews and two established methodologies in strategic management research, exploratory factor analysis and cluster analysis, were used to analyze the data.

The results suggest that despite increasing competitive capabilities of Chinese firms, their maintenance strategies are often restricted to corrective maintenance. Only very few Chinese firms have already implemented predictive maintenance approach, total productive maintenance programs or the strategic outsourcing of maintenance activities.

The research limitations stem from typical issues related to the use of exploratory factor analysis and cluster analysis (for example reliance on the subjective judgment of the researcher or the provision of clusters although no meaningful groups are embedded in the sample).

The findings highlight potential strategies for Chinese firms to improve their maintenance management.

This paper deals with a neglected area of operations management by exploring the maintenance approaches in fast growing Chinese manufacturing industries.

As public–private partnerships (PPPs) have become preferred and veritable approach to deliver affordable housing, the seemingly lack of understanding of the significant factors that impact on success has become a notable setback. This study aims to delineate significant factors that can support decisions in affordable PPP public housing delivery.

Largely, a questionnaire survey was adopted to elicit insights from practitioners, policymakers and experts to develop an evaluative decision support model using an analytical hierarchy process and multi-attribute utility technique approach. Further, an expert illustration was conducted to evaluate and validate the results on the housing typologies.

The results revealed that energy efficiency and low-cost green building materials scored the highest weighting of all the criteria. Furthermore, multi-storey self-contained flats were found to be the most preferred housing typology and were significantly influenced by these factors. From the model evaluation, the scores on the factors of sustainability, affordability, cultural values and accountability were consistent across all typologies of housing whereas that of benchmarking, governance and transparency were varied.

The decision support factors captured varied dimensions of key factors that impact on affordable PPP housing that have not been considered in an integrated manner. These findings offer objective and systematic support to decision-making in affordable PPP housing delivery.

The appearance of social media in small and medium enterprise (SME) business operations seems to be increasing in recent years. SME owners have started to understand that digital marketing tools can benefit their businesses significantly. Hence, in this study, we explore further the relationship between organisations and customers, and how SMEs use social media as an opportunity to develop their enterprises. We report the results by relying on qualitative methods to explore the insights from a wider stakeholder perspective. The findings contribute to the existing literature in agreement with the latest theories that SMEs in Greece are aware of the hidden opportunities and try to apply branding with the combination of social media. This study explores further the role of electronic word of mouth (eWOM) in a business transition, customers' experience and competitive business advantage.

Expressions of pride may elicit others’ envy. In the consumer context, prior research has repeatedly demonstrated that such envy significantly affects consumers’ attitudinal and behavioural responses towards the object of envy. This paper aims to investigate whether this pride-envy relationship is bi-directional. Does being envied by others affect consumers’ self-directed feelings of pride, as well as their subsequent attitude towards a product (i.e. the object of envy)?

Three experiments examined how emotional reactions of envy from others may influence consumers’ subsequent affective and attitudinal responses towards their own product or purchase. The first experimental study (n = 129) examined whether exposure to benign envy from others evokes higher levels of authentic pride and positively influences product attitude. The second experiment (n = 159) investigated whether exposure to malicious envy from others evokes high levels of hubristic pride, and therefore, negatively influences product attitude. The third study (n = 80) was a quasi-field experiment seeking to provide further empirical support for the relationship between benign (vs malicious) envy and authentic (vs hubristic) pride and their effects on attitude.

The first experiment showed that when participants observed expressions of benign envy towards them, they expressed authentic pride, which ultimately increased positive attitudes towards the product. The second experiment showed that when participants observed expressions of malicious envy towards them, they expressed hubristic pride, which, in turn, reduced positive attitudes towards the product. The effect of malicious envy was further moderated by susceptibility to social influence, whereby the indirect effect of malicious envy on product attitudes was only significant among participants with high susceptibility. The third experiment demonstrated the relationship between benign (vs malicious) envy and authentic (vs hubristic) pride and the effects on attitude in a quasi-field study.

The present paper aims to fill a research gap by showing how being the recipient of others’ malicious or benign envy affects consumers’ self-directed feelings of pride, as well as their attitude towards a product that is the object of envy.

The current research is among the first to show that the emotional expressions of other consumers can influence existing consumers’ affective responses and attitudes towards a product. These findings highlight the importance of building a positive culture and community around brands and products, whereby other consumers’ consumption of the brand or product is perceived positively.

To the best of the authors’ knowledge, this study is the first empirical evidence demonstrating that others’ expression of benign (malicious) envy may lead to the self-feeling of authentic (hubristic) pride, which has a downstream effect on attitude towards the product.

Female smallholder farmers in low-income countries face barriers to accessing capital and commodity markets. While agricultural cooperatives provide services that contribute to the income and productivity of small-scale producers, evidence of cooperatives' social and economic empowerment of female smallholders remains limited. We apply Sen's capability approach to female entrepreneurs' socioeconomic empowerment to examine whether women's participation in a coffee and microfinance cooperative from rural western Uganda benefits their social and economic position within their household. First, we study the relationship between women's cooperative participation and their household coffee sales and savings. Second, we investigate the link between women's cooperative participation and their intra-household decision-making and whether the inclusion of the husband in his wife's cooperative strengthens or lowers women's decision-making power.

We carry out a case study of a hybrid coffee and microfinance cooperative that promotes social innovation through the integration and empowerment of female smallholders in rural Uganda. Using a cross-sectional survey of 411 married female cooperative members from 26 randomly selected self-help groups of Bukonzo Joint Cooperative and 196 female non-members from the identical area, employing propensity score matching, this paper investigates the benefits of women's participation in a coffee and microfinance cooperative in the Rwenzori Mountains of western Uganda. We present and discuss the results of our case study within an extensive literature on the role of institutions in collective action for women's empowerment.

Our findings provide new empirical evidence on female smallholders' participation in mixed cooperatives. Our results indicate that women's participation in microfinance-producer cooperatives appears to be a conditional blessing: even though membership is linked to increased women's intra-household decision-making and raised household savings and income from coffee sales, a wife with a husband in the same cooperative self-help group is associated with diminished women's household decision-making power.

The focus of this study is on female coffee smallholders in an agricultural cooperative in rural western Uganda. In particular, we focus on a case study of one major coffee cooperative. Our cross-sectional survey does not allow us to infer causal interpretations. Also, the survey does not include variables that allow us to measure other dimensions of women's empowerment beyond decision-making over household expenditures and women's financial performance related to savings and income from coffee cultivation.

Our empirical results indicate that female smallholders' cooperative membership is associated with higher incomes and coffee sales. However, husband co-participation in their wives' cooperative group diminishes wives' decision-making, which suggests that including husbands and other family members in the same cooperative group may not be perceived as an attractive route to empowerment for female smallholders. For these reasons, an intervention that encourages the cooperation of both spouses and that is sensitive to context-specific gender inequalities, may be more successful at stimulating social change toward household gender equality than interventions that focus on women's autonomous spheres only.

While the literature thus far has focused on microfinance's potential for women's empowerment, evidence on agricultural cooperatives' affecting women's social and economic position is limited. First, our findings provide novel empirical evidence on the empowering effects of women's participation in a self-help group-based coffee cooperative in rural Uganda. Second, our data allows us to explore the role of husbands' participation in their wives' cooperative and SGH. We embed our hypotheses and empirical results in a rich discussion of female entrepreneurship, microfinance and cooperative literature.
