Abstract
Purpose
This study aims to investigate the influence of CEO attire formality on consumers’ perceptions of corporate image, drawing on first impression theory and spillover effect theory.
Design/methodology/approach
Four experimental studies were conducted to test the proposed effect, the underlying mechanism and the boundary condition.
Findings
The formality of CEO attire significantly influences consumers’ perceptions of corporate image. Specifically, formal CEO attire creates a stronger perception of corporate authority among consumers, mediated by perceived rule-following of the CEO. In contrast, informal CEO attire leads to a stronger perception of corporate friendliness, mediated by perceived psychological distance of the CEO. Moreover, a matching effect exists between the type of industry and CEO attire formality, where consumers perceive a greater match between authoritative industries and formally dressed CEOs, and between friendly industries and informally dressed CEOs. This alignment strengthens consumers’ corporate attitudes.
Practical implications
The findings offer valuable insights for CEOs aiming to foster a positive image through their attire, providing strategic guidance for aligning corporate image with industry characteristics.
Originality/value
This research extends the understanding of how consumers’ perceptions of CEO attire can spill over to affect the corporate image, offering a novel perspective on corporate image communication.

Abstract
Purpose
Two time metaphors are often adopted to express the passage of time: the ego-moving metaphor that conceptualizes the ego as moving toward the stationary event (e.g. we are approaching the holiday) or the event-moving metaphor that conceptualizes the event as moving toward the stationary ego (e.g. the holiday is approaching us). This paper aims to investigate the influence of the time metaphor on regulatory focus, as well as its downstream marketing implications.
Design/methodology/approach
Five studies were conducted. Studies 1a–1c examined the moderating effect of the valence of events on the relationship between time metaphors and regulatory focus. Studies 2–3 investigated the downstream marketing implications of the above effects.
Findings
The findings indicated that compared to the event-moving metaphor, the ego-moving metaphor is more likely to evoke a promotion focus when consumers anticipate a positive event. However, when the event is negative, the ego-moving metaphor is more likely to evoke a prevention focus compared to the event-moving metaphor.
Research limitations/implications
This research extends the previous literature on regulatory focus activation by showing that time metaphors affect regulatory focus, and that event valence plays a critical moderating role in the relationship.
Practical implications
Many companies rely on positive events (e.g. holidays, anniversaries) to market their products. The findings of this research suggest that companies promoting products with promotion-related benefits or products with higher risks should adopt an ego-moving metaphor to describe the coming of the event. In contrast, companies promoting products with prevention-related benefits or products with low risks should adopt an event-moving metaphor to describe the coming of the event.
Originality/value
This research showed that the effects of time metaphors on consumers’ regulatory focus depend on the valence of the events. It also demonstrated the downstream implications of time metaphors by showing that time metaphors influence consumer product choices and financial decisions.

Abstract
As green marketing is a critical function of green supply chain management, it has generated a great deal of discussion in public discourse and academic research. Interestingly, there is a gap in the research on how a company can effectively invest and manage various green marketing activities. Thus this paper aims to introduce a grey multiple criteria decision-making methodology to investigate the relationships between green marketing activities and performance outcomes (environmental and business performance). This paper seeks to make the following contributions to the green supply chain management literature. First, review the literature to identify implementation activities for green marketing from green supply chain management literature. Second, develop a methodology to evaluate relationships of green marketing activities by integrating grey number and rough set method. Third, obtain various decision rules relating the various green marketing activities to the environmental and/or business performance outcomes through an illustrative application within an incomplete information system. Knowing those rules to help in the implementation, management, and evaluation of these green marketing activities is valuable to both researchers and practitioners. Included in the discussion are insights into how these rules for individual and aggregated performance (environmental, business, and joint performance) may be evaluated. Practical and research implications of this work are detailed in the final section of this paper.

Abstract
Purpose
This paper aims to investigate the crucial roles of textured surfaces on oil-impregnated polytetrafluoroethylene (PTFE) created by a facile tattoo strategy in improving tribological properties.
Design/methodology/approach
Pored PTFE (PPTFE) was prepared by mixing powder PTFE and citric acid and experienced a cold-press sintering molding process. Subsequently, textured surfaces were obtained with using a tattoo strategy. Surface-textured PPTFE was thus impregnated with polyethylene glycol 200, yielding oil-impregnated and pore-connected PPTFE.
Findings
This study found that oil-impregnated and surface-textured PPTFE exhibited excellent tribological performances with an 82% reduction in coefficient of friction and a 72.5% lowering in wear rate comparing to PPTFE.
Originality/value
This study shows an efficient strategy to improve the tribological property of PTFE using a tattoo-inspired surface texturing method.

Abstract
Purpose
The rural revitalization is a significant indicator of social development in China. Despite the crucial role that local governments play in coordinating urban and rural development, rural areas continue to face limited investment opportunities and scholarship on the impact of local government competition on urban–rural income disparity is scant, especially lacking empirical research from the spatial perspective. The authors contribute to closing the knowledge gap by exploring the spatial spillover effect of local government competition using the sample of China.
Design/methodology/approach
This study evaluated the urban–rural income inequality using the Theil index and constructed the spatial Durbin model to analyze the data by the method of maximum likelihood estimation.
Findings
The findings from the Theil index showed that the income gap is significant between city and countryside in China, with being wider in the western region compared to the eastern region. The evidence from the spatial Durbin model revealed that, in the same province, local government competition widens this gap, while competition from neighboring regions prompts a reduction in this gap in this province.
Practical implications
The authors recommended some policy implications, such as supporting the development in underdeveloped regions and improving the promotion evaluation criteria for local officials.
Originality/value
This article is original in exploring the spatial effects of local government competition on the urban–rural income gap. In addition, instead of using a single proxy to measure the urban–rural income gap, in the current paper, the Theil index for evaluating the disparity is incorporated.

Abstract
Purpose
This paper aims to prepare an oil-impregnated porous polytetrafluoroethylene (PTFE) composite with advanced tribological properties using citric acid as a novel pore-forming agent.
Design/methodology/approach
Citric acid (CA) was used to form pores in PTFE, and then oil-impregnated PTFE composites were prepared. The pore-forming efficiency of CA was evaluated. The possible mechanism of lubrication was proposed according to the tribological properties.
Findings
The results show CA is an efficient pore-forming agent and completely removed, and the porosity of the PTFE increases with the increase of the CA content. The oil-impregnated porous PTFE exhibits an excellent tribological performance, an increased wear resistance of 77.29% was realized in comparison with neat PTFE.
Originality/value
This study enhances understanding of the lubrication mechanism of oil-impregnated porous polymers and guides for their tribological applications.

Abstract
Purpose
Adding Pd element to Au wire can improve the reliability of Au-Al bonding, but the mechanism of Pd element has not been well revealed so far. The purpose of this study is to reveal in more detail the mechanism of the role of Pd elements in Au/Al bonding.
Design/methodology/approach
In this paper, the microstructure changes and tensile data of 99.99% (4N) gold wire and 99% (2N) gold wire with 1 at % Pd were compared through high-temperature thermal aging treatment of the specimens, so as to explore the influence mechanism of Pd element on Au-Al bonding reliability.
Findings
The addition of Pd element effectively reduces the thickness of intermetallic compounds (IMCs) layer and strengthens the fracture tension and reliability. Compared with the 4N specimen, the average thickness of the IMCs layer of the 2N specimen under the same conditions is reduced by 1 µm, and the tensile value of the 2N specimen is increased by 1−3 g. Stored at 200°C for 200 h, the failure rate of bond point of 4N specimen reached 94.64%, and that of 2N specimen was 20%, with a difference of 4.73 times.
Originality/value
Through comparative analysis of the data, this study found that the doping of Pd element in Au-Al IMCs in the early stage slowed down the growth rate of the IMCs, and the precipitation of Pd element in the late stage to form a better Pd-rich layer hindered the element mutual diffusion behavior between Au and Al.

Abstract
Purpose
This study aims to present a numerical study on the flow and heat transfer performance of a water-cooled tube with protrusions in different geometrical parameters.
Design/methodology/approach
A new type of enhanced heat exchanger tube is designed. Protrusions are formed on the inner surface of the tube by mechanical expansion, compression and other processing methods. A three-dimensional numerical symmetry model is established by ANSYS for studying the influence of protrusion distance, protrusion radius and protrusion arrangement on flow and heat transfer characteristics in turbulent flow.
Findings
The results show that the protrusions increase the heat transfer area and improve the heat transfer effect but also increase the flow resistance. Performance evaluation criteria (PEC) is applied to evaluate the flow and heat transfer characteristics of convex tubes. When adopting the aligned protrusions arrangement, the radius of 2 mm and distance of twice the protrusion radius is most heat transfer effect. The PEC of protrusion tubes with a staggered arrangement are higher than those in aligned arrangement, and the maximum value is 2.36 when Reynolds number is 12,000.
Originality/value
At present, most of the protrusion technology applications are based on the cold plate heat dissipation of electronic devices, and the flow path is rectangular. Convex tube heat exchanger is a high-efficiency heat exchanger, which uses convex tubes instead of smooth tubes in tubular heat exchangers to enhance heat transfer and widely used in petroleum, chemical, textile, oil refining and other industries.

Abstract
Purpose
To improve the accuracy of parameter prediction for small-sample data, considering the existence of error in samples, the error circle is introduced to analyze original samples.
Design/methodology/approach
The influence of surface roughness on fatigue life is discussed. The error circle can treat the original samples and extend the single sample, which reduces the influence of the sample error.
Findings
The S-N curve obtained by the error circle method is more reliable; the S-N curve of the Bootstrap method is more reliable than that of the Maximum Likelihood Estimation (MLE) method.
Originality/value
The parameter distribution and characteristics are statistically obtained based on the surface roughness, surface roughness factor and intercept constant. The original sample is studied by an error circle and discussed using the Bootstrap and MLE methods to obtain corresponding S-N curves. It provides a more trustworthy basis for predicting the useful life of products.

Abstract
Although China has claimed since 2005 that it will move towards a more market-oriented system of managing its foreign exchange, it has remained, in part, a managed economic system. This chapter examines the relative importance of fundamentalist, chartist and currency arrangements in determining the RMB exchange regime using both traditional linear and non-linear artificial intelligence models. We find that the emphasis on the US dollar as a reference currency has declined. Fundamentalist forces are becoming strong determinants of the currency exchange. The genetic programming approach is among the best performing in minimizing forecasting error.
