Abstract

Purpose

Three-way decision (3WD) and probabilistic rough sets (PRSs) are theoretical tools capable of simulating humans' multi-level and multi-perspective thinking modes in the field of decision-making. They are proposed to assist decision-makers in better managing incomplete or imprecise information under conditions of uncertainty or fuzziness. However, it is easy to cause decision losses and the personal thresholds of decision-makers cannot be taken into account. To solve this problem, this paper combines picture fuzzy (PF) multi-granularity (MG) with 3WD and establishes the notion of PF MG 3WD.

Design/methodology/approach

An effective incomplete model based on PF MG 3WD is designed in this paper. First, the form of PF MG incomplete information systems (IISs) is established to reasonably record the uncertain information. On this basis, the PF conditional probability is established by using PF similarity relations, and the concept of adjustable PF MG PRSs is proposed by using the PF conditional probability to fuse data. Then, a comprehensive PF multi-attribute group decision-making (MAGDM) scheme is formed by the adjustable PF MG PRSs and the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method. Finally, an actual breast cancer data set is used to reveal the validity of the constructed method.

Findings

The experimental results confirm the effectiveness of PF MG 3WD in predicting breast cancer. Compared with existing models, PF MG 3WD has better robustness and generalization performance. This is mainly due to the incomplete PF MG 3WD proposed in this paper, which effectively reduces the influence of unreasonable outliers and threshold settings.

Originality/value

The model employs the VIKOR method for optimal granularity selections, which takes into account both group utility maximization and individual regret minimization, while incorporating decision-makers' subjective preferences as well. This ensures that the experiment maintains higher exclusion stability and reliability, enhancing the robustness of the decision results.

Abstract

Purpose

The purpose of this study is to assess the effect of the national culture on the performance of a construction project in the UAE. This study benchmarks reason for the success or failure of construction projects from the cultural perspective.

Design/methodology/approach

This study takes a case study approach, using the qualitative research method. Data were collected through participant observation and project records as part of the lessons learned and the data were analysed using the coding procedure of grounded theory. Re-confirmation and cross-checking interviews were also conducted to confirm the correctness of the coding. The qualitative data were expressed in quantitative terms to signify statistically the effect of the national culture on the construction project. In this way, the research methodology employed triangulation in its data analysis.

Findings

This study found differences in the national culture of the Chinese construction project management teams in overseas construction projects in the UAE. The level of uncertainty and long-term orientation contributed to the success of one of the construction projects under scrutiny and the failure of the other.

Research limitations/implications

The study was limited to two construction projects in the UAE. Further research into construction projects is required to validate whether the national culture is generally an element to consider in overseas construction projects.

Practical implications

The research study provides reasons for the success and failure of the two projects from the perspective of differences in national culture. Understanding the cultural differences in international construction projects should help to resolve project issues before these need to be terminated. The termination of a project has economic and social implications for all the stakeholders.

Originality/value

No research study was found to have identified the national culture dimensions of overseas construction project management teams in the UAE. The longitudinal study helped to understand cultural assimilation during the execution of construction projects in the UAE.

Abstract

Purpose

This study aims to enhance the understanding of what significance consumers place on different aspects of corporate social responsibility (CSR) when evaluating and purchasing grocery brands and products.

Design/methodology/approach

The paper builds on existing literature and theories on CSR and marketing, as well as literature on consumers' perceptions of CSR related issues. The Swedish empirical study has two parts; the first explorative stage based on qualitative method and in‐store face‐to‐face interviews through which important consumer attitude‐based attributes of social responsibility are identified in a grocery context. The second quantitative part is based on questionnaires that describe the grocery brand positions and performances along these attributes.

Findings

Results point to three general attitude‐based dimensions for CSR positioning and that retail brands can indeed, in relation to leading national brands, build a CSR image. Further, this image is shown to have an impact on consumers' intention to buy. This is also the case for “me‐too” retail brands. The CSR dimension of greatest impact on overall CSR image is product responsibility, whereas human responsibility influences the customer purchase intentions the most. Environmental responsibility, perhaps the most commonly used CSR dimension, is in this study recognised to exert least impact on both overall CSR image and on purchase intentions.

Research limitations/implications

This study is limited to a Swedish context and to one specific purchase situation. Future studies could involve validation of factor structure, relationship between CSR and preference, and ability to positioning in another market, perhaps in more mature markets in terms of well‐developed structures of CSR and health/organic organic products (e.g. the UK). A postal survey would allow the use of longer and evaluated measurement scales previously used in organic food research.

Originality/value

This study substantiates that retailer brands can indeed be distinctly positioned according to aspects other than price, e.g. as here exemplified, the concept of CSR. This relationship has hitherto not been identified outside the UK. The finding that CSR is less clearly connected to the expected dimension of environmental responsibility entails new added knowledge to this research field. The analysis has, moreover, resulted in more a simplified description of the basic dimensions of CSR containing three instead of, as often in the literature, six dimensions.

Abstract

Purpose

This study aims to explore the attitudes and perceptions of Chinese coffee consumers towards robot baristas, considering the proliferation of automated entities within China's coffee sector.

Design/methodology/approach

Employing the extended Technology Acceptance Model 2 as its theoretical framework, this research conducts in-depth interviews with 30 Chinese coffee consumers. The laddering technique is utilized, supplemented by video simulation. Thematic analysis is subsequently employed to scrutinize the data.

Findings

The findings delineate six pivotal themes encapsulating Chinese coffee consumers' perceptions of robot baristas – Perceived Introvert Friendliness, Perceived Novelty, Perceived Intellectual Discrepancies, Perceived Efficiency and Reliability, Perceived Emotional Disconnection, and Perceived Labour Market Disruption. Moreover, six motivational themes are identified - Social Status Boosting, Openness to Experience, Ease of Use, Tech-Driven Affordability, Reliable and Uncompromising Quality, and Resistance to Overbearing Service.

Research limitations/implications

The study is limited by its focus on a specific cultural context. Future research could explore cross-cultural perspectives.

Practical implications

The findings of this study offer guidance on how to market and position robotic barista services to appeal to consumer preferences and drive adoption.

Social implications

Understanding consumer perceptions of robotic baristas has broader social implications, particularly in terms of labour market disruption and the potential impact on traditional coffee professions. Businesses can navigate the social implications of automation more effectively and foster greater acceptance of technological innovations within society.

Originality/value

This study offers insights into the inclinations of Chinese coffee consumers, thereby facilitating informed decision-making and the formulation of effective strategies to expedite the adoption of robotic service.
