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

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

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

ADSORPTION OF MERCURIC ION FROM AQUEOUS SOLUTIONS USING MODIFIED FLY ASH

In this study, fly ash was treated with NaOH solution (FAN) before modifying with (3-mercaptopropyl) triethoxysilane - MPTMS (FAMPS). By using FTIR, FESEM, XRD, EDX, and BET techniques, the change in structure, composition and morphology of FAN and FAMPS was evaluated. The FTIR spectra of FAN and FAMPS showed that there is no chemical reaction between the MPTMS and FAN. After modification, the FAMPS has a rough surface with composition difference from the FAN. Mercuric ion adsorption behavior as well as adsorptionisotherm models (Langmuir and Freundlich) of the FAN and FAMPS were also investigated and discussed. Thanks to FAN modification, the mercuric ion removal percent of the FAMPS was higher than that of the FAN. Owing to the adsorption data, Freundlich isotherm modelwas fitted for the mercuric ion adsorption process

Model prihvaćanja tehnologije i putevi do online lojalnosti potrošača na tržištima u razvoju

The technology acceptance model (TAM) has been well-known for decades. However, the global adoption of the Internet creates new interests in utilizing TAM in e-commerce and the post-consumption intention, especially in emerging markets. Data was collected from 758 online customers via a web-based survey in Vietnam. Particular contribution of the results is that perceived usefulness, perceived ease of use, fairness, trust and the quality of the customer interface have direct or indirect impacts on customer satisfaction and customer loyalty. Moreover, in emerging markets, trust was outlined as the strongest factor contributing to customer satisfaction and leading to customer loyalty.Model prihvaćanja tehnologije (engl. technology acceptance model – TAM) dobro je poznat već desetljećima. Međutim globalno prihvaćanje interneta potiče novo zanimanje za primjenu TAM-a u e-trgovanju i postkupovnoj namjeri, posebice na tržištima u razvoju. Podaci su prikupljeni online anketiranjem 758 potrošača u Vijetnamu. Poseban doprinos rezultata jest u tome što pokazuju da percipirana korisnosti jednostavnost korištenja, poštenje, povjerenje i kvaliteta korisničkog sučelja imaju izravan ili neizravan utjecaj na zadovoljstvo i lojalnost potrošača. Nadalje, na tržištima u razvoju povjerenje je istaknuto kao najsnažniji čimbenik stvaranja zadovoljstva potrošača koje vodi lojalnosti potrošača
