    Influenza is a common respiratory disease caused by the influenza virus, and each outbreak can result in a large number of infections and deaths worldwide. Predicting the dynamics of influenza outbreaks could be useful for decision-making regarding the allocation of public health resources. Due to the rapid advancement of science and technology in recent years, significant improvements have been made in influenza early warning and prediction, and the original systems have been improved and diversified. In this review, we gather several common influenza prediction systems and early warning methods, as well as some strategies to minimize prediction errors. In addition, we discuss the various data sources and collect the prediction situation on local, regional, national, or global level. Last but not least, we summarized the accuracy and advantages and disadvantages of various prediction methods.

    To investigate current status of the cultural literacy level of Traditional Chinese Medicine (TCM) health among college students majoring in medical and healthcare in the Zhuhai and Macau, the results of the survey can provide evidence for the government to formulate appropriate policies, and promote the development of Chinese medicine talents in the Guangdong-Hong Kong-Macau Greater Bay Area. Stratified cluster sampling was used to sample college students, and the data were analyzed by Χ2-test test and Logistic regression. A total of 964 questionnaires and 927 valid questionnaires were obtained. The overall level of health literacy of the sample population was 31.1%, the five-dimensional literacy level, from high to low, is healthy lifestyle literacy, cultural knowledge literacy, basic concept literacy, information comprehension ability, public appropriate methods literacy. There were significant differences between the literacy level of the students and the analysis results of their domicile, grade and major (P <0.05). The overall level of health cultural literacy among college students in Zhuhai and Macau is higher than that of national residents, but the scores in all dimensions are uneven. Domicile, grade and major are the factors that affect the level of dimensions of literacy. The colleges in Zhuhai and Macau should emphasize the importance of TCM health cultural literacy education and further improve the level of TCM health cultural literacy of students in Guangdong-Hong Kong-Macau Greater Bay Area.

    Currently, the global economy is grappling with novel challenges that traditional business growth models cannot sufficiently address for sustainable development. Employees, as crucial participants in production and operational activities, are fundamental to fostering innovation within teams and organizations. Therefore, studying employee innovative behavior is imperative. Innovative behavior, essentially an active trait, is primarily motivated by a proactive personality. This study aims to investigate the factors that encourage proactive personality, thriving at work, and innovative behavior. Utilizing structural equation modeling, data from 456 employees were meticulously gathered and analyzed. Findings reveal that employees with a higher degree of proactive personality are more likely to demonstrate innovative behaviors. Notably, thriving at work mediates the relationship between proactive personality and innovative behaviors. Furthermore, the study indicates that an innovative climate amplifies the positive impact of a proactive personality on thriving at work. In simpler terms, a more robust innovation climate bolsters the positive effects of a proactive personality. Lastly, the study discovered that an innovation climate positively affects the indirect influence of proactive personality on innovation behavior. When an organization has a stronger innovation climate, the mediating effect of individual thriving at work is enhanced. The paper concludes with a discussion on the theoretical and practical implications of these findings and offers directions for future research.

    Based on a summary of the history of language and cultural exchanges between China and Sudan, this paper analyzes the background of the development of International Chinese Language Education (ICLE) in Sudan from perspectives such as political mutual trust, economic and trade reciprocity, and diplomatic interaction. Then, it studies the current situation of ICLE from the viewpoint of Chinese educational institutions, primary education, and higher education. After that, it analyzes the challenges faced by the development of ICLE from viewpoints like military conflicts and a shortage of educational funds. At long last, it attempts to propose countermeasures and suggestions from the points such as teaching institutions and teaching channels. In Sudan, the education of Chinese for Specific Purposes (CSP) has demonstrated exceptional characteristics, a remarkable development history, and outstanding current and future trends. Examples include“Art Education + Chinese Language Teaching (CLT)”, “Medical Education + CLT”and “Vocational Training + CLT”, all of which have a relatively long history and a significant amount of potential for growth in the future.

    A company is a significant business organizational form characterized by its independent legal personality. During its formative, pre-incorporation phase, the promoter carries out essential preparatory tasks, including contract agreements. This research scrutinizes the legal norms and liabilities relating to a promoter's contractual conduct from the departmental law's internal viewpoint, while applying identity theory from the sociology of law's external perspective to interpret such conduct. The study underscores role identity, role expectation, and commitment as critical connectors between the individual promoter and society. It also highlights the anticipatory role of law and the importance of specific norms in shaping the promoter's contractual liability, thereby establishing a paradigm from identification to action. The paper further deliberates on the theoretical and practical relevance of encouraging entrepreneurship, upholding fairness, and mitigating disputes during the company's formative phase.

    Abstract: The global obesity issue is progressively worsening, becoming a significant public health challenge. According to statistics, the global obesity population continues to increase, surpassing 30% of the total population, with China's obesity figures also rapidly escalating, exceeding 50% of adults being diagnosed as overweight or obese. Obesity not only affects individual health but also closely associates with various chronic diseases such as cardiovascular disorders, diabetes, imposing a substantial burden on society and economy. Currently, there exists a variety of methods to address obesity, including dietary control, physical activity, pharmaceutical interventions, and surgical treatments. However, among these approaches, bariatric metabolic surgery (BMS) has been proven to be one of the most effective methods, particularly for patients with obesity-related comorbidities, showcasing more significant results. This trend has given rise to the development of metabolic surgery in the context of obesity. China, being one of the nations most severely affected by the obesity issue, has witnessed over two decades of development in the field of metabolic and bariatric surgery. At present, this field is experiencing a phase of rapid expansion. This paper provides an overview of the background and concept of metabolic and bariatric surgery in China, reviews the historical progression and development of this field, including various surgical techniques and technological breakthroughs. Furthermore, it delves into the challenges and opportunities faced by metabolic and bariatric surgery in China and presents recommendations for its future advancement.

    Residents’ attitude towards tourism is a key factor affecting the sustainable development of a destination. In recent years, the rapid development of Macau tourism industry has led to insufficient tourism carrying capacity, which has brought pressure and inconvenience to the lives of local residents. And the contradiction between host and guest has become increasingly prominent. However, with the outbreak of COVID-19, the emotional attitudes of both residents and tourists have changed. This study aims to explore how the emotional solidarity of Macau residents towards tourists influences their tourism impact attitude in the post-COVID-19 pandemic. Through quantitative method, SPSS24 and SmartPLS3.0 were used to analyze the data from 422 questionnaires from Macau residents. The results showed that different dimensions of emotional solidarity between Macau residents and tourists after the epidemic had different degrees of positive influence on their tourism impact attitude. This study re-examined the emotional solidarity between residents and tourists and the changes in the relationship of emotional solidarity in the post-pandemic era. The conclusion provided practical significance for Macau destination management organization.

    There are many problems in teaching Chinese as a foreign language, such as unclear identification of teaching content, unclear teaching objectives, unclear teaching objects, non-standard teaching difficulty and poor teaching effect. Based on the concept-based instruction and design which is widely used in the International Baccalaureate curriculum as one of the six major approach to teaching, this paper will adopt the viewpoint of Mei Lichong (1994), which divided the culture teaching contents of TCFL into declarative and procedural knowledge to set up “concept, knowledge, skill” three-dimensional structure of culture instruction and design of TCFL. It contains two sub-structures: the structure of knowledge: cultural concept, cultural theme, cultural knowledge, and the structure of process: cultural concept, cultural process, cultural strategy/skill. The concept-based instruction and design, proposing the KUD model, making the curriculum from two-dimensional to three-dimensional, will greatly promote the students' deep understanding, make students go from cultural crossing to cultural transcendence in cross-cultural communication, and improve the discipline literacy in second language learning.

    As globalization continues to develop, second language learning and multilingualism have become increasingly common. As a result, the study of third language acquisition has gained attention. This study explores the process of word order acquisition and language transfer among Thai L1, English L2, and Chinese L3 learners, using Chinese word order acquisition as a starting point. Based on theoretical findings from previous studies on third language acquisition, the study found that Thai learners made different transfer choices at different levels and in linguistic elements, based on their perception of language distance. These choices showed non-unitary sources and directions of transfer in terms of language order and vocabulary. The mechanism of their choices depended on reducing cognitive difficulties in third language acquisition and enhancing learning effectiveness. At the level of Chinese word order acquisition, L1 (Thai) transfer was dominant, and learners showed an overall resistance to L2 (English) transfer. However, L2 (English) did have an effect on the acquisition of L3 (Chinese), mainly at the lexical level. Additionally, learners' language learning experiences and methods accumulated in L2 (English) or L3 (Chinese) facilitated the development of their meta-linguistic awareness, which had a positive effect on the development of multilingual competence.

    To promote economic transition and development, tax cut and fee reduction are essential policies implemented by State Council and regional governments. Consequently, the effects of such tax incentives are worth of being explored. Based on a sample of listed A-share firms from 2010 to 2019 in China, we investigate how the R&D expenses additional deduction policy plays a role in R&D manipulation and then the related economic consequences. It is found that the professionality and complexity of R&D investment may facilitate R&D manipulations and the enforcement of tax authorities can restrain it in turn. Meanwhile, R&D manipulations can be used to mask manager's opportunistic and self-dealing incentives and then achieve high level of corporate tax avoidance which will increase tax and operation risks. Besides, we also provide several suggestions on implementations of R&D expenses additional deduction to policy makers.

    During the COVID-19 pandemic, people's livelihoods and economies have been significantly impacted, necessitating targeted economic assistance from governments. However, appropriate legal classifications and constraint standards remain contentious. Examining the economic aid in the Macau Special Administrative Region reveals that theories like social assistance and administrative compensation are insufficient. New theoretical models accounting for infectious disease outbreaks should be employed to establish a solid legal foundation. Developing principle-based standards requires optimizing the social assistance model, enhancing decision-making in universal assistance selection, and fostering progressive principles. Concurrently, a framework centered on economic regulation, while incorporating social assistance, should be constructed. This approach ensures comprehensive macro-level coverage and delivers targeted, equitable aid at the micro-level.

    The performances of Thunderstorm in Hong Kong and Macau in recent years can be rehearsed according to their own characteristics. Using dialect, dancing, there are also amateur forms of practice. However, behind these localized adaptations, it reflects the dramatist' different concepts of Thunderstorm and even the drama. The idea itself does not mean abstract, it just needs to be expressed in the corresponding artistic appearance or form, so that the idea can gain its vitality and art can obtain the desired ideal. Therefore, through the investigation of the Hong Kong and Macau version of Thunderstorm in recent years, we can not only notice the regional interpretation of Thunderstorm, but also have a glimpse of the dramatic art view of the Hong Kong and Macao drama circles. And Thunderstorm has gone beyond the masterpiece itself, reflecting the rich connotation of literature. The original author's profound thoughts on society and life are worthy of our deep consideration.

    Based on existing literature, this study employed untimed grammaticality judgment tasks and target word monitoring experiments to investigate the development of explicit and implicit knowledge among Thai learners of the Chinese language. The research findings reveal that language proficiency and the presence of sentence violations significantly impact the development of explicit knowledge, whereas the influence of grammatical construction types is statistically insignificant. Furthermore, language proficiency and grammatical construction types exert significant effects on response times in implicit knowledge tests. Notably, native Chinese speakers exhibit the shortest response times in target word monitoring tasks, while low-proficiency Thai learners of Chinese show the longest response times. Additionally, the study identifies an interaction between language proficiency and grammatical construction types. Lastly, language proficiency, grammatical construction types, and the presence of sentence violations significantly influence participants’ accuracy judgments in implicit knowledge tests. These results collectively suggest an inherent asynchrony and imbalance in the development of explicit and implicit knowledge, with language production being contingent on the monitoring role of explicit knowledge. The attainability of learner's implicit knowledge to a native speaker level appears to be contingent on the complexity of the learned Chinese language segments.

    Using a psychological experimental paradigm of cross-linguistic repetition priming, the present study examines the semantic access mechanism of Russian-English-Chinese trilingual students with different levels of L3 Chinese and the significant priming effects found in all cases. The results show that: (1) for those who are proficient in both L2 and L3, the semantic access to L3 Chinese lexicon is facilitated by L2 English but not by L1 Russian; (2) for those who are proficient in L2 but not in L3, the semantic access to L3 Chinese lexicon is facilitated by L2 English, while L1 Russian plays an inhibitory role; (3) in addition to language proficiency, trilingual semantic access is also influenced by cross-language factors such as language distance, language status, and recency of use.

    National image often undergoes dramatic change over the course of emergency events, and the use of media language will highlight these changes. This study focuses on the relationship between media language and national image construction in the reporting of public health emergencies in Macao. Based on the three-dimensional framework of Fairclough's critical discourse analysis, this paper analyzes the diachronic reports of Macao Daily News on China's fight against COVID-19 in 2021 and the discourse function of national image construction from three aspects: text, discourse practice, and social practice. It is found that the respect to high-frequency words and collocations, the media tends to choose words indicating positive evaluation. In terms of agenda setting, more positive words are used for reporting. Authoritative information sources of domestic mainstream media are the main sources of information, and information is conveyed in an indirect way that can better reflect the position of Macao media. It has established a discourse on COVID-19 prevention and control that provides positive guidance and is easier for the audience to identify with, and plays a positive role in building the image of an amiable, credible, and respectable world power that is capable of bearing the responsibility of fighting against the pandemic through a united front.

    Cervical cancer and HPV-related diseases can be effectively prevented through HPV vaccination. Yet, in mainland China, there is limited understanding of the associated factors among young people who are at the optimal age for HPV vaccination. This study aimed to investigate the HPV-related knowledge, attitudes, and willingness to vaccinate among this population, analyze associated factors, and provide a basis for primary and secondary cervical cancer prevention strategies. We performed a cross-sectional questionnaire survey, recruiting 892 participants. Of these, 86.7% had heard of the HPV vaccine, and 83.3% reported their willingness to receive the HPV vaccination. Our findings suggest that the most crucial factor influencing vaccine uptake is females who had heard of the HPV vaccine, believed in their ability to self-determine vaccination, encouraged their sexual partners to get vaccinated, and were in favor of incorporating the vaccine into routine vaccinations. In conclusion, despite high willingness, Guangzhou university students have a low actual HPV vaccination rate, with internet and social media being the main, yet insufficient, sources of HPV knowledge. Enhancing vaccination coverage in China requires boosted awareness, cost regulation, and national campaign implementation.

    Chinese art needs to go global, and first and foremost, there must be outstanding contemporary Chinese artworks. Every art form has its own creators, and contemporary Chinese art needs to have internationally recognized masters who can present our values to the world. These values should embody universal human values. The process of spreading Chinese culture to the world is a process of both seeking and spreading knowledge. Only when seeking knowledge and spreading knowledge are combined can a global cultural dialogue be generated.

    Based on the “zai + NPL” indicating “real space location”, this paper takes further study on the semantic relationship between V which indicates action and “zai + NPL” which indicates location after their combination in Chinese. First, upon a deep observation of the example sentences from CCL corpus, this paper shows that the semantic types of “V + zai + NPL” structure can be divided into three categories at the synchronic level: action result, dynamic progress and static-existence. Secondly, compared with the semantic type of structure “zai + NPL + V”, it has been found that the action V of admitting the structure has formed a continuum in semantic features. Combined diachronic corpus and previous researches, this paper proved that the three semantic types of “V +zai+ NPL” are actually a diachronic continuum from weak to strong. Finally, this paper explored the causes of word order of the combination of “zai+NPL” and V, finding that the formation of structure “V+zai+NPL” is driven by both Abstract Principle and Iconic Principle, while the structure “zai+NPL+ V” is driven only by the Iconic Principle.

    Film is a medium for spreading cultural heritage and a carrier for its living preservation, which helps to maintain the vitality of cultural legacy. The first local film in Macao, The Bewitching Braids, not only presents Macao’s World Cultural Heritage--the Historic Centre of Macao, but also reflects Macao’s intangible cultural heritage such as religious beliefs, festive rituals and local dialects, making it an important visual archive for the study of Macao’s history and culture. Taking The Bewitching Braids as the research text, based on Roland Barthes’ theory of image rhetoric, this paper analyzes the embodiment of Macao’s tangible and intangible cultural heritage elements and symbols in the film’s linguistic message layer and the denoted image layer, as well as their connoted roles in shaping the characters, promoting the plot, and expressing the theme of the film, so as to explore how to tell the cultural heritage stories through film.

    Within the paradigm of concept-based language instruction, it’s propounded that educators should underline not only the practicality of language usage but also the cognitive aspects of language to enhance the effectiveness of language instruction. The genesis and growth of teaching philosophies are driven by a mix of internal and external influences. Utilizing grounded theory, this research determines that individual impetuses, the practicalities of teaching, dynamic feedback, institution allure, and motivations for career development constitute the five primary elements that sway the evolution and crystallization of concept-based teaching philosophies. Together, these five elements and their thirteen secondary components mould the language teaching belief model. The development of this teaching belief ensues along a trajectory of ‘external stimulus-subjective experience-self-identification.’ The particular attributes of concept-based language teaching beliefs are also brought to light in this paper.

    Chinese criminal policy in dealing with the “COVID-19” Pandemic is effective, which emphasizes “rule of law”, rather than the traditional formulation of “strict” or “lenient”. It provides new thinking mode and analyzing sample to the exploration of emergency mechanism. Criminal policy can only affect the implementation of criminal law. Temporary criminal policy is a “variable” of criminal law, which can make timely response in emergencies. While the long-term criminal policy is a “constant”, which requires the application of criminal law keep consistent with it. During the epidemic, the distinction between the crime of impairing the prevention and treatment of the infectious diseases and the crime of endangering public security by dangerous means fully embodies this principle.

    It is not sufficient for enterprises to implement low-cost strategies based solely on the internal resources’ optimization. In this connection, from the perspective of external supplier relationships, ABJ model and Weiss model are used to study the antecedents of enterprise cost stickiness, with a view to opening the “black box” of enterprise cost control. With reference to the sample of A-share listed enterprises from 2011 to 2019, it is found that supplier concentration is negatively correlated with cost stickiness, and that the capability of managers enhances the relationship between the supplier concentration and cost stickiness. Furthermore, the degree of supplier fluctuation is positively correlated with enterprise cost stickiness, but the capability of managers can inhibit the impact of the supplier fluctuation on cost stickiness. Based on the research findings, it is proposed that enterprise cost control should start from both internal management and external supplier relationships, and competition between enterprises has expanded to the supply chain level. The capability of managers exists and is effective in the competition at the supply chain level, as it will help enterprises adjust the impact of external supplier relationships on internal cost stickines.

    The development of the discipline in patient safety is a common concern in the domain of patient safety worldwide. The “World Annual Summit on Patient Safety, Science and Technology” hosted by the Patient Safety Campaign Foundation in the United States since 2013 has provided a development framework for patient safety, known as “Patient Safety, Science, and Technology” (PS-ST). PS-ST emphasizes maintaining an open state of science and technology related to patient safety, in order to widely absorb the achievements of S&T and develop patient safety knowledge, and paying attention to the “practical and feasible patient safety solutions”, however, there seem to be some shortcomings. PS-ST has not formed its own complete theoretical system, and does not have a complete humanistic concept of patient safety. To become an independent and mature discipline in Health Science, there is still a long way . It is recommended to enrich and improve the discipline of patient safety according to the development concept of “Patient Safety Science & Technology and Humanities” (PSSTH), and to comprehensively construct the PSSTH knowledge system for building a safer health system and a highly reliable healthcare system. To fill the gap, China should develop her own theoretical system and produce textbooks in this field. PSSTH can not only better adapt the needs of China to cultivate “New Medical Science” talents who have a good grasp in “ Medicine, Engineering, Science and Literature”, to address the challenges of economic and social development, new technological revolution and new health risks, but also promote the high-quality development of public hospitals. Based on the understanding of the essence of patient safety and the need for comprehensive prevention and control of Patient Safety Events (PSIs), this article proposes and briefly discusses this viewpoint by using innovative thinking.

    Lung cancer treatment has been revolutionized by the discovery of somatic mutations in epidermal growth factor receptors (EGFRs) and the development of EGFR tyrosine kinase inhibitors (TKIs). However, in most cases, non-small cell lung cancer (NSCLC) patients who are treated with gefitinib eventually develop resistance. The purpose of this study was to investigate the effect of Aloe vera (L.) Burm. f. (A. vera) extract combined with gefitinib on gefitinib-resistant NSCLC cell lines. The cytotoxicity assay showed that there was a minimal inhibitory effect of A. vera on cell proliferation in A549, PC-9, and H1975 cells, while the combined use of A. vera and gefitinib resulted in a significant inhibitory effect on cell growth in a concentration-dependent manner. Importantly, compared to other cell lines, H1975 proliferation was inhibited by the combined treatment more effectively. The IC50 values at 24 h decreased from 37.92 ± 1.19 to 20.09 ± 1.03 μM for H1975 cells. As a result of the combined treatment of A. vera and gefitinib, the migration ability of H1975 cells was decreased compared with that of the gefitinib group. Moreover, A. vera significantly increased the gefitinib-induced apoptosis in H1975 cells and the combination treatment induced G2/M phase arrest in H1975 cells. Furthermore, the Wnt/β-catenin pathway was inhibited in H1975 cells of the high-concentration combination group, suggesting that A. vera is a potential anticancer therapeutic adjuvant for gefitinib-resistant NSCLC with the EGFR-T790M mutation.

    The United Nations Convention on the Law of the Sea has established a relatively well-developed system of conservation and optimum utilization of fishery resources, which provides a sufficient legal guarantee for the sustainable development of fish stocks. However, the growing problem of global climate change, in particular sea level rise and ocean warming, has significantly challenged the regime for the conservation and optimum utilization of fishery resources under the United Nations Convention on the Law of the Sea, which is mainly manifested in the possible change of fisheries resources jurisdiction, the deterioration of the overfishing situation, and the increase of international fisheries disputes. Based on this, measures such as maintaining or freezing the territorial sea baselines, preserving the rights of maritime features, strengthening cooperation among countries, and improving regional and international governance mechanisms may stabilize the current international maritime order.

    With the development of higher education, the quality assurance system of university-level programs has received increasing attention in recent years. This article introduces the quality assurance system in the assessment of the Chinese language program at Xi’an Jiaotong-Liverpool University, an international joint venture university. It is proposed that establishing internal and external moderation systems for assessment, introducing assessment preparation, and module marking moderation reports will effectively improve the quality of assessment, thereby enhancing higher education institutions’ academic standards. The article concludes with suggestions for enhancing the quality of assessment in higher education institutions in China.

    This study examines the familiarity of university students in Guangdong Province with the vocabulary associated with the COVID-19 pandemic, using a survey questionnaire for data gathering. The research intends to uncover differences in understanding of pandemic-related terminology across gender, academic majors, and grade levels. Implementing sociolinguistic and speech communication analysis, it is revealed that terms like ‘novel coronavirus pneumonia COVID-19’ attract more attention from male students. Medical students, from an academic discipline viewpoint, showed greater interest in terminology including ‘epidemic name’, ‘organization’, ‘place name’, ‘pathological symptoms’, ‘equipment name’, ‘medical term’, ‘professional term’, ‘other terms’, and ‘occupational group’. Familiarity with vocabulary related to ‘pathological symptoms’ differed significantly by grade level, with freshmen showing less understanding than sophomores and juniors. The paper investigates the reasons for the preferential attention of male students to ‘proper nouns’, and why medical students paid more attention to professional language associated with the new coronavirus epidemic given their social background and identities. The cognitive viewpoint is used to explain freshmen’s less extensive knowledge of terms like ‘pathological symptoms’ when compared to sophomores and juniors. The ‘knowledge gap’ hypothesis is utilized to explain the lack of difference in attention to pandemic-related vocabulary across genders, grade levels, and disciplines. Finally, the study adopts a communication perspective to discuss how variations among recipients’ impact communication effectiveness.

    The study of the perceived effectiveness of privacy policy effectiveness on customer trust aims to help those privacy policy providers improve the transparency of mobile payment and customer privacy protection. Based on the cognitive appraisal theory, we propose a research model of how the perceived effectiveness of privacy policy effectiveness influences customer trust has been proposed. And Furthermore, quantitative analysis has been employed to test the research hypotheses developed from this research work. through quantitative analysis. The results showed that through the dual-path mediation of privacy risk perception and privacy security perception, the perceived effectiveness of privacy policy effectiveness positively affects privacy awareness, and influences customer trust. This research provides a new research perspective in theoretical research by using cognitive appraisal theory to explain how perceived privacy policy can enhance customer trust; in practice, the findings suggest service providers enhance their privacy policy disclosure to retrieve consistency between permission requirements and protection measures for reducing privacy risk and improving privacy security, thereby enhancing trust of consumers in mobile payment.

    Tourists hold different attitudes towards technology, and the different perceptions and subsequent impacts of these attitudes on online reviews are topics worthy of discussion. Therefore, this study focuses on how tourists’ attitudes toward technology affect their decision speed, by developing a model of the relationship between tourist attitudes toward technology and decision speed. The study used the Technology Adoption Propensity (TAP) scale to measure the tourists’ attitudes toward technology and test the influence on decision speed mediated by trust, persuasiveness, and helpfulness. Respondents are invited to complete the questionnaire after reading genuine hotel online reviews. The findings show that tourists’ attitudes toward technology positively affect tourist perceptions (trust, persuasiveness, and helpfulness) and decision speed through the mediating role of persuasiveness and helpfulness. The originality and value of this study lie in exploring the decision-making process of tourists from a new perspective and innovatively exploring the internal mechanism of its impact on the decision speed of tourists from the perspective of tourists’ attitudes toward technology.
