Density Functional Theory Study of Geometrical and Electron Structures of Al18Ti Aluminum Clusters and Their Catalytic Activity toward the CO Oxidation
The B3LYP functional in conjunction with 6-311+G(d) basis set was employed to optimize geometrical structures, followed by frequency calculations of the Al19+ and Al18Ti clusters, converging to the double icosahedron structure, and the Ti places at the top apex of the double icosahedron in the case of Al18Ti cluster. The changes in the electron structure of the clusters have been determined; accordingly, there is energy level splitting of the 1P, 1D, 1F, 2P, and 2D shell orbitals and the appearance of 3d orbitals of the Ti in the electron configurations. The catalytic ability of the Al18Ti cluster for the CO and O2 reaction has been investigated initially; thus, the Ti atom plays a central role in binding to CO and O2, weakening both the O=O and C≡O bonds and facilitating the formation of CO2.
Factors Affecting Profits at Companies in the Construction Industry Listed on the Ho Chi Minh City Stock Exchange
The study examines and evaluates the impact of factors such as revenue growth rate, fixed asset investment, enterprise size, financial leverage, current liquidity ratio, economic growth rate, and inflation rate on the profitability of construction companies listed on the Ho Chi Minh City Stock Exchange. The study uses data from 20 construction companies listed on the Ho Chi Minh City Stock Exchange for the period 2015–2023, extracted from annual financial reports. The study uses panel data regression models, including ordinary least squares (OLS) models, fixed effects models (FEM), and random effects models (REM), as well as tests to select the appropriate model. The REM model is the initial appropriate model, but autocorrelation, heteroscedasticity, and endogeneity occur simultaneously. Therefore, continue to estimate the model using the GMM regression method so that the estimated results are unbiased and reliable. The findings show that revenue growth rate, firm size, and liquidity have positive effects on profitability, while financial leverage and economic growth rate have negative effects.

Artificial Intelligence Applications in Tourism
Artificial intelligence (AI) technologies have transformed the travel and tourism industry. The purpose of this study is to systematically analyze the applications of artificial intelligence in tourism and provide an overview of current development trends, challenges, and future directions. We reviewed 290 articles after thoroughly evaluating the literature using relevant keywords. The results show that many sectors within the tourism industry, such as customer service, marketing, and operations management, are utilizing artificial intelligence. Robots, chatbots, and AI-driven systems are becoming useful tools, providing personalized experiences, rapid services, and better decision-making. AI presents significant potential benefits, especially in regions such as Europe, China, and India that are at the forefront of AI adoption. The tourism and travel industry in Vietnam is also gradually incorporating these technological advancements. However, its adoption requires careful consideration of issues such as data privacy, job displacement, and the digital divide between regions. The use of AI technology in the tourism sector can lead to development and competitive opportunities, but we must address its ethical, legal, and social impacts. One of the recommendations of the study is for stakeholders in tourism to invest in AI research and development, ensure collaboration between industry, academia, and government, and promote AI-related skills in the workforce in this field.

A Model for Maximizing Customer Satisfaction and Loyalty
The acronym DIRFT, which stands for “Do right the first time,” encapsulates the CE (customer experience) strategic management model, which aims to maximize customer satisfaction and loyalty, ultimately leading to increased revenue. DIRFT is often the declared goal of every organization. However, regardless of intentions, even with the best training and resources, businesses often fail to get it right the first time. Therein lies the role of strategic service in the customer experience, which consists of two main parts: setting expectations and preparing the customer to use the product, and, if the customer experience is not perfect, aligning customer interactions with the service process. Setting expectations and helping customers get the most from your product is the essence of strategic customer service.

An Initial View of Investigating Roman Jakobson’s Semiotic Theory in Translation
This article introduces a model for bringing semiotics into English-Vietnamese translation research based on Roman Jakobson’s theory. It is a semiotic translation known by the name “cultural translation” or “cultural transposition.” Through the pioneering theory of Ferdinand de Saussure and Charles S. Peirce, it examined the connection between translation studies and semiotics around the late 19th and early 20th centuries. It is Saussure, who is the first of many people not to follow the approach to semiotics, suggesting the role of semiotics as an independent science, exploiting aspects of semiotic thinking, and not relying on structure. This article also mentioned that Charles S. Peirce and Roman Jakobson advocated for and developed the theory of semiotic translation (1959–1969) because of its helpfulness in translation. Therefore, the universal mechanism of semiotics embodies the application of semiotics to translation, and vice versa. Furthermore, Jakobson’s research uncovered many differences between semiological languages. Jakobson devides this form of translation into three types of semiotic translation (tripartite divisions of translation): intralingual translation, interlingual translation, and intersemiotic translation. This article delves into the advantages and disadvantages of this theory, which can greatly aid in translation. For instance, it explains how one can use “another word, more or less synonymous, or resort to circumlocution” in intralingual translation. This article aims to introduce translation professionals or graduate students majoring in translation to the initial concept of semiotic translation which is a helpful solution to the problem of untranslability and translation difficulties compared to traditional methods. It is very important to explore and learn this method to be able to innovate in the English-Vietnamese translation industry and vice versa.

Cross-Linguistic Influence in English Usage among Vietnamese EFL Learners: A Cross-Domain Analysis
In the context of Second Language Acquisition (SLA) in Vietnam, learners’ language production is significantly affected by cross-linguistic influence (CLI) from their first language (L1). While previous studies have often examined semantic, pragmatic, and phonological transfer in isolation, there remains a lack of integrated qualitative research focusing on high school Vietnamese EFL learners in under-resourced learning contexts. This study investigates the L1 interference phenomenon by examining how Vietnamese learners transfer different linguistic features from Vietnamese to English across semantic, pragmatic, and phonological domains. Based on Transfer Theory and Error Analysis, the study analyzes the language production data collected from classroom-based tasks completed by grade 11 students (n=20) at a local language center. The study identifies three primary categories of transfer: semantic, pragmatic, and phonological, demonstrating that these transfer-related patterns systematically affect communicative effectiveness rather than constituting isolated learner errors. In addition, this study contributes to SLA research by highlighting the interdependence of semantic, pragmatic, and phonological transfer in high school Vietnamese EFL learners’ interlanguage development. Furthermore, the paper discusses evidence-based pedagogical measures that can be used to avoid negative transfer and improve the communicative competence of Vietnamese EFL learners.
Social Context Face-Saving Strategies in English and Their Equivalents in Vietnamese Language
This article explores what face-saving -”giữ thể diện”- is and what strategies used in social interactions within Vietnamese and English-speaking cultures. Face-saving, which involves maintaining dignity and avoiding embarrassment, plays a key role in ensuring respectful communication. While important and rather familiar in both contexts, the ways in which face-saving is practiced differ notably. The article examines verbal and non-verbal communication, politeness strategies, and conflict avoidance methods used to preserve “face”. It highlights that Vietnamese speakers in their high-context culture often rely on indirect and highly polite forms of expression, whereas English native speakers in their low-context culture tend to communicate in a more direct and explicit manner. Furthermore, the article discusses how cultural norms influence perceptions of respect, shame, and social harmony, shaping behavior in interpersonal situations. By comparing these cultural patterns, the study provides valuable insights into intercultural communication and emphasizes the importance of cultural awareness in fostering effective and respectful interactions across diverse settings.
