NEUTRAL AND CATIONIC TITANIUM-DOPED SILICON CLUSTERS: GROWTH MECHANISM AND STABILIT

We report ab-initio study on neutral and cationic titanium-doped silicon clusters TiSin0/+              (n = 1-10). The growth patterns for both neutral and charged clusters are revealed. The neutral TiSin clusters follow a consistent rule of addition: the larger TiSin cluster is built up by adding a Si atom on the smaller TiSin-1 cluster. However, the Ti atom prefers to substitute at a high-coordination position to form the cationic clusters. The neutral TiSin clusters is more stable than the pure Sin+1 clusters while the cationic TiSin+ is less stable than the pure ones. Both neutral and cationic clusters tend to loss Si atom rather than Ti atoms.

HEROISM IN ERNEST HEMINGWAY’S SHORT STORIES

Ernest Hemingway, a distinguished writer, is well-known for his writing theory called the “Iceberg Principle.” This theory is used to introduce the concept of Heroism, which depicts the images of heroes differently from the traditional stereotype. His novels and collections of short stories were written permeating the Iceberg Principle. Among them, In Another Country, Old Man at the Bridge, and The Old Man and the Sea characterized the heroes with their unique characteristics which readers needed to dig out to get a deeper insight into man’s fate with emotional overtones. The current study, with a qualitative and descriptive approach, illuminates Heroism in these short stories. The results show that there are five aspects that Hemingway applied to reflect his Heroism including age, life tragedies, isolation, persistence, and stoicism. Besides, throughout the three stories, one can see the development of Hemingway's heroes as they strive to reach perfection during his literary career.  Article visualizations

Antecedents of the Intention and Behavior Toward Purchase of Counterfeit Luxury Goods in an Emerging Economy: a Study of Young Vietnamese Consumers

This study examines some antecedents of the intention and behavior toward buying counterfeit luxury goods among young consumers in Vietnam, an Asian emerging economy. The data was obtained from university undergraduate students in Hanoi, the capital of Vietnam. The results of structural equation modeling show support for most of our hypotheses. The findings indicate that materialism (the centrality component) has positive impact on attitude toward purchase of counterfeit luxury goods. Attitude and subjective norm toward counterfeit luxury goods are found to be positively related to purchase intention, while perceived behavioral control is not found to have a direct impact on purchase intention. In addition, perceived behavioral control and purchase intention are found to be significant predictors of purchase behavior. The research findings are discussed and implications for managers and policy makers are provided. &nbsp

Spatial Clustering Analysis Of Dengue Hemorrhagic Fever In The First 9-Monthsof 2023 In Ho Chi Minh City, Vietnam

Background: Dengue hemorrhagic fever is a notable vector-borne viral disease, currently becoming the most dreaded worldwide health problem in terms of the number of people affected. The objective of this study is to investigate spatial clustering of dengue hemorrhagic fever incidence in the first 9-months of 2023 in Ho Chi Minh city, Vietnam. Methods: the global Moran’s I statistic, Moran’s I scatterplot and local statistic were employed to spatial clusters (high-high and low-low) and spatial outliers (low-high and high-low) in the study area of Ho Chi Minh city. The first and third order of contiguity were used to constructe spatial weight matrix. Results: it was found from a case study of the first 9-months of 2023 in Ho Chi Minh city, a total of four high-high clusters, two low-low spatial clusters were detected in urban area and rural areas in the north and south of the Ho Chi Minh city, respectively when using the first order contiguity (statistically significance at the 0.05 level). For the case of using the third order of contiguity, a total of six high-low, two low-high spatial clusters and one low-low spatial cluster were successfully identified. Conclusions: the study results has proven the effective use of the global Moran’s I statistic, Moran’s I scatterplot and local Moran’s I statistic in the identification of spatial clustering of dengue hemorrhagic fever incidence

First report of Mesocriconema sphaerocephalum (Taylor, 1936) Loof, 1989 associated with carrot (Daucus carota subsp. Stativus) in Vietnam

Our study recorded the presence of Mesocriconema sphaeroce phalum on carrot in Hanoi city and Hai Duong province in Vietnam. This species was identified by morphometric, morphological characterizations, and molecular characterization of D2D3 of 28S rDNA sequence. To our knowledge, this is the first report of M. sphaerocephalum on carrot in Vietnam

Antecedents and Consequences of Status Consumption Among Urban Vietnamese Consumers

This study examines the antecedents and consequences of status consumption in the transitional economy of Vietnam. Both qualitative (focus groups and in-depth interviews) and quantitative methods (survey) were employed in this investigation. To test the proposed model and hypotheses, a large consumer survey was conducted in the two biggest cities in Vietnam. The results of Structural Equation Modeling provided empirical evidence for the significant impact of most of the proposed antecedents of status consumption. Specifically, modern status orientation, the ‘success’ component of materialism, and both the individualistic self and collectivistic self were found to have a positive impact on status consumption. Traditional status orientation and consumer ethnocentrism were found to be negatively related to status consumption. The findings also suggested the positive consequences of status consumption on satisfaction with status consumption and satisfaction with life in general. Discussion of the research findings and managerial implications are also provided

Some Obstacles In Mathematical Communication Of Students While Learning Continous Functions Lesson

Mathematical Communication is one of the required competencies of the learner in the needs of the real life, and in learning Mathematics, students always have the need to communicate with teacher and other students to solve problems in mathematics, as well as to present the solution or mathematical ideas to the others. However, there are many difficulties with many reasons when they exchange or communicate with the others by mathematical language in classroom. Therefore, the ability for communicating in Math is one of the required competencies of students. In this paper, we try to find out the obstacles which make students have difficulty when they are in mathematical communication while learning continuous functions. The problems set out in this article to assess how difficulties in communication in the Math class, so that we can recommend some possible strategies for teachers to help their students in order to overcome these obstacles in practicing teaching
