Livestreaming commerce is a form of e-commerce that embedded real-time video presentation and social interaction. It provides immersive shopping experience reinforced by high levels of interactivity and instant bidirectional communication. China, as one of the biggest livestreaming markets, has reached 2.3 trillion (CNY) livestreaming commerce market value in 2022. In a 2020 survey, two-thirds of Chinese consumers experienced livestreaming shopping in the previous year. Accordingly, luxury brands, such as Chanel and Louis Vuitton have started to implement livestreaming commerce in China. However, for years, luxury brands have struggled with online commerce as it may impact upon perceptions of exclusivity and dilute brand value. Research on the efficacy of live commerce emerged in recent years and mostly focused on non-luxury brands. However, luxury brands cannot simply copy digital marketing strategies that proved to be effective for non-luxury brands. To date, limited academic attention has been devoted to the luxury commerce in a livestreaming context.

The attitude-behavior gap and intention-behavior gap has not been research extensively. The purpose of this study is to provide a review of moderating or mediating factors on the relationship between intention or attitude and behavior of sustainable tourism. Intention was defined as the degree of a human being’s resolve to perform a certain action. The construct ‘Intention” has been used widely in some theories like the Theory of Planned Behavior. Researchers usually include the intention construct into their research framework to explain the theoretical mechanism. Sustainable or ecological tourism education has been implemented for years and empirical evidence provides us that almost all tourists are alerted to the importance of sustainability. There is a great challenge that tourists’ behavior might not concur with their intention. Policymakers and marketers really want to know the real factors affecting the association between the intention and behavior of sustainable tourism. Tourists’ purchase intention is a rational process and is affected by safety. Tourist behavior is associated with price and service environment which is a mixture of rational and emotional considerations.

People spent around 90% of smartphone usage time on mobile applications (apps). In response to these opportunities, companies have developed branded apps to interact with consumers and facilitate loyalty. However, companies have hard time retaining consumers to their own brand due to the fierce competition in the app market. As such, it is imperative to unveil factors driving continuance intention of branded apps. This is one of a key research themes in a recent literature review of marketing research on mobile apps. Most of prior studies have adopted the utilitarian perspective where perceived usefulness and ease of use are identified as the key drivers. However, the fit perspective has received limited attention. It has gained increasing importance as recent studies have emphasized the role of person-app fit and person-brand fit in driving consumers’ purchase decision performance and as consumers’ lives are highly embedded into branded apps. This study aims to investigate continuance intention of branded apps from the fit perspective. This research selected the target branded apps in Taiwan based on prior studies. A market research firm was contracted to collect data randomly on various social media sites, and its membership database by using online questionnaires. 198 usable questionnaires were obtained. Partial least squares structural equation modeling was used to analyze the data.

This study constructs a model to predict ad attitude when AI influencers act as ad endorsers. In the results, search products and rational ad appeal have more positive ad attitude, perceived empathy and perceived expertise as mediator. These three variables can be reinforced by the consistency of ad appeals and product categories.

This study supplements the literature by determining how restaurant innovativeness is linked to customer advocacy as well as considering self-image congruity as mediator of this relationship. A questionnaire survey of 385 restaurant customers was conducted in Taiwan. The results indicated that restaurant innovativeness is positively related to customers’ self-image congruity and customer advocacy. Customers’ self-image congruity is positively associated with customer advocacy. In addition, self-image congruity mediates the relationship between restaurant innovativeness and customer advocacy. The research contributes to literature by extend the relationships between restaurant innovativeness, self-image congruity, and customer advocacy. Restaurant managers should adopt approaches (e.g. innovativeness-related activities) for enhancing self-image congruity in customers.

Marine industry generates tons of waste, which is usually discarded or used for production of fish feed and low-value silage. However, marine residual raw materials (e.g., skins, heads, liver, and roe after fish gutting and processing) contain lipids rich in omega-3 fatty acid, which has several beneficial physiological effects such as maintenance of normal cardiac function, normal brain function, and normal vision. Food fortification with omega-3 fatty acid derived from marine residual raw materials can therefore provide health benefits and contribute to a circular food system. The current research explores consumer acceptance of the food fortified with microencapsulated fish oil derived from marine residual raw materials. Consumers may be hesitant to try these products due to food neophobia associated with tendency to eat foods with familiar ingredients. The idea of ingredients from normally discarded food parts may seem disturbing. However, there is a growing concern about low utilization of bioresources. Thus, conflicting goals may be in place and there is a need for research on motivations and barriers for consumption of this type of food. To address this, focus group interviews were conducted with 42 Norwegian consumers (7 groups, 4-7 participants each). The sample represented different age groups (20-55 years), genders, educational backgrounds, and income levels. Each participant received a compensation of ca. USD 30. The focus groups discussed food habits, attitude towards the fortified food and utilizing residual raw materials, and reasons for intake/no intake of such food. The interviews were transcribed and analyzed using the constant comparative method. The results indicate that the informants have limited experience with fortified food. However, they demonstrate positive attitude towards the foods fortified with microencapsulated fish oil and appreciate the utilization of residual raw materials. Health benefits are one of the important motivations. Still, the informants are concerned about the fishy taste, as the flavor is also quite crucial. Another barrier is an expected high price for such food. Adding fish oil may also be a problem for vegetarians and consumers with allergies. Thus, transparent information about the food ingredients is essential. The results also highlight the importance of food’s sensory characteristics. The current study advances understanding of the consumer acceptance of the food with residual raw materials (so far under investigated in the literature), and thus provides a basis for finding an efficient strategy for communicating its benefits to consumers. It also provides societal health benefits and positive environmental effects due to the increased intake of omega-3 and better utilization of unused bioresources.

An important segment, tourism e-commerce live streaming (TEcLS) has emerged as a new marketing channel actively embraced by destination marketing organizations (DMO) and tourist firms due to the COVID-19 pandemic. China, Japan, Australia, and many other nations have been selling such tourism products on various platforms. Live e-commerce generates a real-time interactive virtual environment that can be called a livescape. However, many tourism destinations or companies are unaware of the marketing science implications of live streaming and are unsure of their effectiveness or the intricacies of marketing live streaming. Previous research has explored the factors influencing consumer purchase behavior from the product, technology, and live-streamer perspectives, arguing that the advantages of breaking through time and space constraints, strong interactivity, the experience of reality, technological ease of use and usefulness, and celebrity aura encourage online purchases. However, limited investigation has been carried out on the impact of customers’ value-co-creation in livescape when watching tourism live streaming on their purchase intentions considering the key role of engagement. This calls for specific investigation of the phenomenon to facilitate live streaming design and tourism marketing. This study aims to explores the factors influencing consumer purchase intentions in the livescape based on a value co-creation research framework. Compared to traditional e-commerce, livescapes provides the “many-to-many” social presence and an immersive value co-creation platform. Thus, we focus on why and how social presence inspires customer engagement, ultimately leading to purchase intentions. This study finds that, as a crucial marketing tool, the social presence of tourism livescapes can promotes customer engagement, which in turn results in intentions to purchase tourism live-streaming products. Additionally, the mediating role of inspiration (inspired-by and inspired-to) between social presence and customer engagement is examined to reveal the influence mechanism in the tourism context. Finally, this study examines how to create an effective tourism livescape to enhance tourists social presence experience and inspire their engagement, which in turn increases their purchase intention.

Fear of missing out (FOMO) refers to the customer's perception of being anxious for not engaging in an experience. FOMO is an anxiety feeling positively associated with social media usage that one cannot catch up on something important in life. Fear of missing out (FOMO) marketing appeals initiated from social media usage were found to significantly affect consumer purchase decisions including choice of destination. Consumers usually browse social media and social networking sites such as forums and reviews in online tourism agents (OTAs) when they make travel decisions. Although FOMO is expected to affect tourists' perception and urgency in making a tourism decision, the use of FOMO-laden message to promote travel destination through different types of influencers has not yet been widely studied. This study fills this research gap by examining the effect of using FOMO laden content to promote travel destination through different types of influencers. An online experiment was conducted with four experimental conditions in which different influencers share about a destination using the same FOMO-laden message: (1) travel KOL, (2) tourists who post user-generated-content (UGC), (3) personal friends, and (4) a control condition with the absence of influencer and FOMO message. The 984 respondents were randomly assigned into one of the four experimental conditions. Data collected was analysed using PLS-SEM and PLS-MGA. Results indicated that anticipated elation, anticipated envy, and social influence predicted 30.2% variance of FOMO and FOMO explained 31.6% of variance of intention to visit the destination promoted. Multi-group analysis (PLS-MGA) found that exposure to message shared by travel KOL and personal friends significantly strengthen the FOMO feeling of participants resulting in strong intention to visit the destination promoted. UGC posted by tourists showed similar effect as the non-FOMO laden control group and are less significant in driving the FOMO feeling that leads to visit intention. Findings of this study provide insights into how effectiveness of destination promotion can be enhanced by using FOMO-laden message on social media through influential influencers.

With the continuous development of science and technology, unmanned ship has gradually become a hot spot in the field of marine research. In practical applications, unmanned ships need to have long-range navigation and high efficiency, so that they can accurately perform tasks in the marine environment. As one of the key technologies of unmanned ship, path planning is of great significance to improve the endurance of unmanned ship. In order to meet the requirements, this paper proposes a path planning method for long distance unmanned ships based on reinforcement learning angle precedence ant colony improvement algorithm. Firstly, canny operator is used to automatically extract navigation environment information, and then MAKLINK graph theory is applied for environment modelling. Finally, the basic ant colony algorithm is improved and applied to the path planning of unmanned ship to generate an optimal path. The experimental results show that, compared with the traditional ant colony algorithm, the path planning method based on the improved ant colony algorithm can achieve a voyage duration of nearly 7 km for unmanned ships under the same sailing environment, which has certain practicability and popularization value.

The development of heteroatoms doped inorganic nanocrystal-carbon composites (INCCs) has attained a great focus for energy applications (energy production and energy storage). A precise approach to fabricate the INCCs with homogenous distribution of the heteroatoms with an appropriate distribution of metal atoms remains a challenge for material scientists. Herein, we proposed a facile two-step route to synthesize INCC with doping of metal (α-Fe2O3) and non-metals (N, P, O) using hydrogel formed by treating hexachlorocyclotriphosphazene (HCCP) and 3, 4, 5-trihydroxy benzoic acid (Gallic acid). Metal oxide was doped using an extrinsic doping approach by varying its content and non-metallic doping by an intrinsic doping approach. We have fabricated four different samples (INCC-0.5%, INCC-1.0%, INCC-1.5%, and INCC-2.0%), which exhibit the uniform distribution of the N, P, O, and α-Fe2O3 in the carbon architecture. These composite materials were applied as anode material in water oxidation catalysis (WOC); INCC-1.5% electro-catalyst confirmed by cyclic voltammetry (CV) with a noticeable catholic peak 0.85 V vs RHE and maximal current density 1.5 mA.cm−2. It also delivers better methanol tolerance and elongated stability than RuO2; this superior performance was attributed due to the homogenous distribution of the α-Fe2O3 causing in promotion of adsorption of O2 initially and a greater surface area of 1352.8 m2/ g with hierarchical pore size distribution resulting higher rate of ion transportation and mass-flux.

Graphene-derived materials are an excellent electrode for electrochemical detection of heavy metals. In this study, a MnO2/ graphene supported on Ni foam electrode was prepared via ultrasonic impregnation and electrochemical deposition. The resulting electrode was used to detect Pb(II) in the aquatic environment. The graphene and MnO2 deposited on the Ni foam not only improved active surface area, but also promoted the electron transfer. The electrochemical performance towards Pb(II) was evaluated by cyclic voltammetry (CV) and square wave anodic stripping voltammetry (SWASV). The prepared electrode exhibited lower limit of detection (LOD, 0.2 μM (S/N = 3)) and good sensitivity (59.9 μAμM−1) for Pb(II) detection. Moreover, the prepared electrodes showed good stability and reproducibility. This excellent performance can be attributed to the strong adhesion force between graphene and MnO2, which provides compact structures for the enhancement of the mechanical stability. Thus, these combined results provide some technical considerations and scientific insights for the detection of heavy metal ions using composite electrodes.

Renewed interest in the reinforced carbon graphite composites has intrigued the community in the advanced materials fields. In this work, we present a simple carbon nanofibers reinforced carbon graphite composites synthetic method by incorporating mixture of coal tar pitch, synthetic graphite, pitch coke and the dispersion liquid of carbon nanofibers via liquid-phase mixing process. The impact of carbon nanofiber utilization on the microstructures and mechanical properties of carbon graphite composites are studied systematically. The covalent surface modification of carbon nanofibers effectively improves its microstructure and thereby promotes the carbon graphite composites’ dispersion behavior. We propose that a small amount of carbon nanofibers could promote the carbonization process of carbon graphite composites, facilitating the densification of carbon graphite composites and reducing the undesired open porosity. The amount of 0.7 wt % of carbon nanofiber concentration allows the enhancement of bend and compressive strength of carbon graphite composites up to 36.50 MPa and 60.46 MPa, increased by 167.9% and 146.9% compared with the pure carbon graphite composite, respectively. Our findings can be rationalized due to the improvement in the mechanical strength of carbon graphite composites could be attributed due to pull-out of carbon nanofibers from the matrix and bridging effect across the crack pores within the matrix.

Supercross-linked polymers are widely used as carbon precursor materials due to their abundant carbon sources and low cost. In this paper, a supercross-linked polymer was prepared by the solvothermal method. The supercross-linked polymer as a precursor and the PPyC-800-A was synthesized by activating this with KOH. The microstructure, structure, and electrochemical performances of porous carbon PPyC-800-A were studied at different of temperature and carbon alkali ratio. According to the results, the porous carbon PPyC-800-1:2 is mainly composed of a stack of spherical particles with a high surface area of 1427.03 m2 g− 1, an average pore diameter of 2.32 nm, and a high specific capacitance of 217.7 F g− 1 at a current density of 1.0 A g− 1 in a 6 M KOH electrolyte. It’s retention rate is 97.58% after 5000 constant current charges and discharges. With a specific capacitance decay rate of 21.91 percent, an energy density of 11.96 Wh kg− 1, and a power density of 500.0 W kg− 1, the current density rises from 1.0 A g− 1 to 10.0 A g− 1, exhibiting remarkable electrochemical properties, cycling stability, and energy production performance This study contributes experimental ideas to the field of supercrosslinked polymer-derived carbon materials and energy storage.

It is difficult to optimize the process parameters of directly preparing carbonaceous mesophase (CMs) by solvothermal method using coal tar as raw material. To solve this problem, a Decision Tree model for CMs preparation (DTC) was established based on the relationship between the process parameters and the yields of CMs. Then, the importance of variables in the preparation process for CMs was predicted, the relationship between experimental conditions and yields was revealed, and the preparation process conditions were also optimized by the DTC. The prediction results showed that the importance of the variables was raw material type, solvothermal temperature, solvothermal time, solvent amount, and additive type in order. And the optimized reaction conditions were as follows: coal tar was pretreated by decompress distillation and centrifugation, the solvent amount was 50.0 ml, the solvothermal temperature was 230 °C, and the reaction time was 5 h. These prediction results were consistent with the actual experimental results, and the error between the predicted yields and the actual yields was about − 1.1%. Furthermore, the prediction error of DTC method was within the acceptable range when the data sample sets were reduced to 100 sets. These results proved that the established DTC for chemical process optimization can effectively lessen the experimental workload and has high application value.

RCEP will have a significant impact on ASEAN, China and other contracting parties, significantly enhancing the cooperative levels between ASEAN and other essential economies in the region. It can develop the manufacturing industry in ASEAN and China with higher quality. First of all, this study used the Strengths (S), Weaknesses (W), Opportunities (O) and Threats (T) (SWOT) model to analyze the specific impacts of China’s participation in RCEP on the development of ASEAN’s manufacturing industry. Subsequently, strategic recommendations were put forward for the high-quality development of ASEAN’s manufacturing industry under the RCEP cooperation mechanism from four aspects of SO,WO, ST and WT. As the signing of RCEP provides an excellent development opportunity, the ASEAN member countries should carry out deeper cooperation with China; create new strengths for high-quality development of the manufacturing industry; erect a closer regional industrial chain and the supply chain; and promote the realization of a higher level of regional economic integration between ASEAN and China.

In this paper, we presented a hybrid composite of graphene quantum dots (GQDs)-modified three-dimensional graphene nanoribbons (3D GNRs) composite linked by Fe3O4 and CoO nanoparticles through reflux and ultrasonic treatment with GQDs, denoted as 3D GQDs-Fe3O4/CoO@GNRs (3D GFCG). In this hybrid, the 3D GNRs framework strengthened the electrical conductivity and the synergistic effects between GQDs and 3D GFCG enhanced the oxygen reduction reaction (ORR) activity of the nanocomposite. The results imply that decorating GQDs with other electro-catalysts is an effective strategy to synergistically improve their ORR activity.
