In recent years, the updating speed of products has been significantly accelerated, which not only provides diversified styles for consumers to select from but also makes consumers face selection problems sometimes. In addition, a large number of online reviews for products emerge on many e-commerce websites and influence consumers’ purchasing decisions. The purpose of this study is to propose a method for product selection considering consumer’s expectations and online reviews to support consumers’ purchasing decisions.

The product attributes are divided into two categories, i.e. demand attributes and word-of-mouth (WOM) attributes. For the demand attributes, for which the consumers can give specific quantified expectations, the value function of prospect theory is used to determine the consumer’s perceived values to the alternative products according to consumers’ expectations for these attributes and products’ specifications. For the WOM attributes, for which the consumers cannot give specific quantified expectations, the sentiment analysis method is used to identify the sentiment strengths for these attributes in the online reviews, and then the consumer’s perceived values to the alternative products are determined. On this basis, the product selection methods for single consumers and group consumers are given respectively.

Finally, taking the data of JD.com (https://www.jd.com/) as an example, the practicability and rationality of the method proposed in this paper is validated.

First, a new product selection problem considering consumer’s expectations and online reviews is extracted. Second, the product attributes are considered more comprehensively and are classified into two main categories. Third, the bounded rationality of the consumers in the decision-making process is described more reasonably. Fourth, the sentiment dictionaries for each WOM attribute are constructed and the algorithm step of identifying the sentiment strengths is designed, which can help to identify the sentiment strengths in the online reviews more accurately. Fifth, the situation that a group plans to purchase the same products and the members have inconsistent expectations for the product attributes is considered.

The purpose of this paper is to understand how the context congruity effects of online product recommendations (PRs) by recommendation agents (RAs) influence consumers’ attention to and memory of recommended products in an online shopping environment.

The study focuses on the context congruity effects of online PRs by examining consumers’ browsing patterns and attention characteristics (fixation counts and fixation duration) using an eye-tracking device and by measuring memory performance with an aided memory test. Three types of PRs (highly congruent, lowly congruent and incongruent PRs) and two degrees of involvement (high and low involvement) are considered.

The results of the gaze data show that context congruity effects can influence consumers’ PR attention, but this effect is not moderated by involvements. The results of the memory data show that PR recognition is influenced not only by context congruity effects but also by involvement. Another significant finding is that attention to a PR does not necessarily guarantee better memory performance.

The study significantly contributes to deepening the understanding of how context congruity can influence consumers’ attention to and memory of PRs. The findings also have important managerial and practical implications, such that selecting and presenting PRs should be based on context congruity effects.

First, introducing context congruity effects to investigate the effectiveness of online PRs by RAs not only provides an important theoretical contribution to research on recommendation effectiveness but also enriches its application. Second, the findings suggest that the relationship between visual attention and memory is not definitely positive. Third, to interpret the complex translation process from attention to memory, the authors propose a methodology that considers stimulus attributes, issue involvement, cognitive capacity and cognitive interference.

Cultural differences have been frequently cited as a major source of risks for international joint ventures (IJVs). Cultural differences may cause extensive conflicts in technology, norms and emotion among the international joint venture (IJV) partners. The purpose of this study is to explore the interactive effects of national culture differences (NCDs) and conflict management approaches on the performance of international construction joint ventures (ICJV).

Data were collected using a questionnaire survey method with 143 valid responses. Partial least squares structural equation modeling (PLS-SEM) was used to test the research hypotheses.

It was found that ICJV performance declined with a high degree of NCDs. The negative effect of NCDs on ICJV performance was mitigated by adopting the cooperative conflict management approach; while it was aggravated by adopting the competitive conflict management approach. The findings may provide an alternative way (i.e. adopting the cooperative conflict management approach rather than avoiding or competitive approaches) to address the cultural conflicts in the multicultural project management teams.

Firstly, as NCD negatively impacts performance of ICJVs, project managers should pay attention to cultural issues and learn how to manage them; Secondly, as cooperative and competitive conflict management approaches have different moderating effects on the relationship between NCD and ICJV performance, project managers must choose appropriate conflict management styles in multination teams. Thirdly, as the avoiding approach has no significant moderating effect on the negative relationship between NCD and ICJV performance, it is important for Chinese partners not to employ avoiding approach to deal with conflicts in ICJV.

This study uniquely adds to the literature on cultural issues in managing ICJVs by integrating the moderating effects of conflict management approaches. The interactive effects of conflict management approaches and national cultural differences on ICJV project performance may contribute to the theories regarding conflict management theory in the context of cross-cultural management.
