Building upon the cognition-affect-behavior (CAB) model and script theory, this research aims to enrich the existing literature on historic town tourism consumption by offering empirical evidence of how the cognitive and affective images of historic towns contributes to tourists' memorable tourism experiences (MTE) and revisit intention, while identifying the cognitive image dimensions that are relevant for evaluating historic towns.

An on-site survey was conducted with 486 local tourists who visited the historic towns in Chengdu. partial least squares-structural equation modeling (PLS-SEM) was utilized to assess both the measurement and structural models.

(1) Cognitive image emerged as a significant predictor of affective image; (2) Both cognitive image and affective image had a positive influence on MTE, in which cognitive image played a more dominant role in shaping MTE; (3) MTE was found to strongly predict revisit intention among tourists; (4) MTE and affective image mediated the relationship between cognitive image and revisit intention.

This research highlights the value of incorporating cognitive and affective constructs in predicting MTE, and the proposed integrated framework of the CAB model and script theory exhibits superior predictive power in understanding tourists' revisit intention.

This research provides empirical insights about how historic towns improve their marketing strategies as short day-trip destinations.

This research provides a novel insight on the applicability of an integrated model combining the CAB model and script theory in explaining the revisit behavior of local tourists within the context of historic towns.

This paper investigated the effects of exposure to advertising images on quality of life issues. Affordable products and unaffordable products, as well as control images, were presented to participants of the experiment. Subjects' self-esteem, life-satisfaction and materialism were measured using a battery of scales. Results indicated affordable product images did not affect any dependent variables. However, exposure to unaffordable products enhanced, rather than decreased, Chinese students' self-esteem and life-satisfaction, contrary to results found in previous social comparison research. This suggested that Chinese students were rather optimistic about their future and they used future orientation in their prediction of success. Implications of the study were discussed.

This study aims to investigate the impact of indium (In) content on the thermal properties, microstructure and mechanical properties of Sn-3Ag-3Sb-xIn (x = 0, 1, 2, 3, 4, 5 Wt.%) solders to enhance the performance of tin-based solder under demanding conditions and to meet the urgent need for high-reliability microelectronic interconnection materials in emerging sectors such as automotive intelligent technology, 5G communication technology and high-performance computing.

In this study, Sn-3Ag-3Sb-xIn solder alloys were prepared. The thermal properties of the solder alloys were characterised by differential scanning calorimetry. Subsequently, optical microscopy, scanning electron microscopy, X-ray diffraction and an electron probe X-ray microanalyser were used to analyse the influence of the In content on the microstructure of the solder. The mechanical properties of solder alloys were determined through tensile testing.

As the In content increased, the melting temperature of the Sn-3Ag-3Sb-xIn solder decreased, accompanied by less nucleation undercooling and an expanded melting range. The incorporation of In led to an enhancement in the yield and tensile strengths of the Sn-3Ag-3Sb-xIn solder alloys, but with a concomitant decrease in plasticity. In comparison to commercial Sn-3.0Ag-0.5Cu solder alloys, the yield strength and tensile strength of the Sn-3Ag-3Sb-3In alloy increased by 8.64 and 21.69 MPa, respectively, while the elongation decreased by 11.48%.

Sn-3Ag-3Sb-3In solder alloy was the most appropriate and expected comprehensive properties. The enhancements will provide substantial assistance and precise data references for the interconnection requirements in high-strength interconnection fields, such as automotive intelligent technology, 5G communication technology and high-performance computing.

The purpose of this paper was to prepare a ternary hierarchical rough particle to accelerate the anti-corrosive design for coastal concrete infrastructures.

A kind of micro-nano hydrophobic ternary microparticles was fabricated from SiO₂/halloysite nanotubes (HNTs) and recycled concrete powders (RCPs), which was then mixed with sodium silicate and silane to form an inorganic slurry. The slurry was further sprayed on the concrete surface to construct a superhydrophobic coating (SHC). Transmission electron microscopy and energy-dispersive X-ray spectroscopy mappings demonstrate that the nano-sized SiO₂ has been grafted on the sub-micron HNTs and then further adhered to the surface of micro-sized RCP, forming a kind of superhydrophobic particles (SiO₂/HNTs@RCP) featured of abundant micro-nano hierarchical structures.

The SHC surface presents excellent superhydrophobicity with the water contact angle >156°. Electrochemical tests indicate that the corrosion rate of mild steel rebar in coated concrete reduces three-order magnitudes relative to the uncoated one in 3.5% NaCl solution. Water uptake and chloride ion (Cl^-) diffusion tests show that the SHC exhibits high H₂O and Cl^- ions barrier properties thanks to the pore-sealing and water-repellence properties of SiO₂/HNTs@RCP particles. Furthermore, the SHC possesses considerable mechanical durability and outstanding self-cleaning ability.

SHC inhibits water uptake, Cl^- diffusion and rebar corrosion of concrete, which will promote the sustainable application of concrete waste in anti-corrosive concrete projects.

In this paper, a three-dimensional size-dependent constitutive model of SMP Timoshenko micro-beam is developed to describe the micromechanical properties.

According to the Hamilton's principle, the equilibrium equations and boundary conditions of the model are established and according to the modified couple stress theory, the model is available to capturing the size effect because of the material length scale parameter. Based on the model, the simply supported beam was taken for example to be solved and simulated.

Results show that the size effect of SMP micro-beam is more obvious when the dimensionless beam height is similar or the larger of the value of loading time. The rigidity and strength of the SMP beam decrease with the increasing of the dimensionless beam height or the loading time. The viscous property of SMP micro-beam plays a more important role with the larger dimensionless beam height. And the smaller the dimensionless beam height is, the more obvious the shape memory effect of the SMP micro-beam is.

This work implies prediction of size-dependent thermo-mechanical behaviors of the SMP micro-beam and will provide a theoretical basis for design SMP microstructures in the field of micro/nanomechanics.

This paper aims to focus on the reliability of Sn15Bi–xAg and Sn15Bi–xCu solder joints during isothermal aging.

The effects of Ag or Cu additions on the microstructure, interfacial metallic compound layer and shear strength of Sn–15Bi (Sn15Bi) based solder joints during were investigated. The effects of Ag or Cu additions on the microstructure and tensile properties of Sn15Bi-based bulk solders were also investigated to provide a comprehensive analysis. The interfacial morphology and microstructure were observed by scanning electron microscopy and the composition in the structure was examined by energy dispersive spectrometer. The shear tests were carried out on the as-soldered and as-aged joints using a ball shear tester.

The results revealed that by adding Ag or Cu, the microstructure of Sn15Bi solder can be refined. Ag addition increased the tensile strength of Sn15Bi solder but had little effect on elongation. However, Cu addition decreased the tensile strength and elongation of Sn15Bi solder. For solder joints, Ag addition increased the shear strength and toughness of Sn15Bi/Cu joints but Cu addition decreased the shear strength and toughness of Sn15Bi/Cu joints.

The authors can potentially provide a replacement for Sn40Pb traditional solder with Sn15Bi solder by alloying Ag or Cu due to its lower cost and similar melting point as Sn–Pb solder.

This paper tests if there exists a subjective well-being gap between informal workers in the informal and formal sectors in urban China, and explores the mechanisms behind such differences.

The author develops a simple theoretical model to analyze the effects of the employment sector and work time flexibility on workers' happiness and conducts a descriptive study to examine the relationship between employment type and subjective well-being using the China General Social Survey (CGSS) 2010, 2013, 2015 and 2017 datasets, a nationally representative sample.

The results show that only dependent informal work in the formal sector impairs workers' happiness, while the effect of independent informal work is not statistically significant. The potential mechanisms suggest that independent informal workers have higher working time flexibility and can work more hours to increase their earnings, which increases their subjective well-being. However, it is difficult for dependent informal workers to earn more by working more hours due to poor working time flexibility.

This study indicates that informal workers in the formal sector have lower subjective well-being in urban China and deserve more attention from policymakers. The author also suggests that increasing working time flexibility and encouraging self-employment can contribute to the welfare of informal workers.

Environmental claims in advertising (green ads) provide competitive advantage to firms. This study aims to understand what kinds of environmental claims advertisers make in a developing nation like India. Further, implications for policymakers and advertisers are discussed.

A content analysis of 279 green print advertisements was conducted using a comprehensive list of claim categories identified from the advertising literature. These categories included advertiser profile; ad promotions – type, sector, appeal; claim – nature, type, focus, validity, emphasis; executional elements – illustration setting, presenter, format/structure and environmental issue, identified from past studies and practitioner interviews.

The findings suggest that majority of the advertisers using green ads are manufacturers. Consumer durables, real estate and power sector together constitute one-third of the total green ads. Further, most of the green ads are aimed at influencing consumer behaviour. Though most of the ads contain strong emphasis on environmental attributes, they are ambiguous. A large proportion of claims are credence in nature and lack product identification through environmental certifications. This study also identifies areas of concern including interpretation of the term green, use of multiple certifications, greenwashing and advertisers showing environmental responsiveness through event-based green advertising. Policy recommendations are made based on green advertising regulations governing them across developed and other developing countries.

The content analysis of the green advertisements in this study was limited to newspaper advertisements within the print media. Future studies may use advertisements from different media types, such as the internet ads and television commercials, to examine the effect of media type on the nature of green advertisements. It would also be interesting to examine the role of regulations as a moderator, influencing the claims made in green advertisements.

The findings of this study provide a comprehensive overview of the nature of green advertisements in India. Marketers may use these insights to design effective green advertising strategies.

Most of the extant literature has examined environmental claims in the context of developed nations, where regulations are well established. Very few studies have examined this issue in the context of developing countries. In addition, most of the previous studies have focused on specific issues like greenwashing, appeals and execution elements. The present study contributes to green advertising by examining environmental claims in case of a developing nation like India using a comprehensive list of claim categories. This study also identifies areas of concern and suggests recommendations for policymakers and advertisers.
