Effects of Internal Factors on Financial Performance of Listed Construction-Material Companies: The Case of Vietnam

The research aims to assess internal factors affecting to financial performance so that feasible suggestions could be provided for construction-material firms which are currently listing in the stock market of Vietnam. The authors applied regression for panel data which collected from 30 listed construction-material firms. The findings show that firms’ financial performance are positively affected by the firms’ size, capital structure, capitalization expenditure, and accounts receivable management. The research results also reflect positive relation between firms’ financial performance and business risk. Upon the research results we recommend that the changes should be focus on improving policies about capitalization expenditure; reasonable capital structure and management of inventories.

A propensity score matching analysis of the relationship between forest resources and household welfare in Vietnam

Using secondary data from a socio-economic quantitative household survey in of the North Central region of Vietnam, the main aim of our study is to analyze the causal effect of forest resources on household income and poverty. Based on the observed characteristics of a forest-based livelihood and forest-related activities, we use a propensity score matching (PSM) method to control for potential bias arising from self-selection. The PSM results indicate that households with a forest livelihood had a higher level of income and lower level of poverty than did those without. Interestingly, our findings confirm that a forest-based livelihood offers much higher income than any other type of livelihood adopted by local households. Also, the poverty rate among households with a forest livelihood is lower than those earning non-labor income or engaged in wage/crop and crop livelihoods. Moreover, households whose livelihoods depend on timber forest products (TFPs) and animals (non-TFPs) also had higher income and lower levels of poverty than did those lacking these resources. Among households and provinces, we find differing opportunities deriving from forest resources, suggesting that there are potential barriers hindering local households from pursuing a forest livelihood or participating in some forest activities. Therefore, government policy and regulations on forest management should focus on improving the access of households to forest resources, at the same time enhancing the sustainability of these resources

PRELIMINARY RECONSTRUCTION OF DIET AT A NEOLITHIC SITE IN VIETNAM USING STABLE ISOTOPE AND BA/SR ANALYSES

In order to better evaluate the role plant exploitation played at a Neolithic site (Con Co Ngua, ceramic context dated to 5000 years BP) in Vietnam, we measured the 13C in apatite from human teeth at this site as well as from a nearby Metal Period site (Nui Nap), with a carbon date of 1670 years BP, where 13C and 15N from collagen were also measured. Ba:Sr ratios at both sites were determined in order to estimate the importance of marine versus agricultural food sources. Results are consistent with incipient plant exploitation at Con Co Ngua, while dietary C3 plants that might have included rice played a smaller role than at Nui Nap. Marine sources appear to be more significant at the earlier site

Health and the Experience of Childhood in Late Neolithic Vietnam

The article aims to examine aspects of mortuary behavior in late Neolithic/early Bronze Age (Phung Nguyen phase) populations represented at the site of Man Bac in Viet Nam, specifically how mortuary behavior illuminates the role of children, and adult attitudes toward children. In addition, the authors discuss biological characteristics of the human sample, focusing particularly on the child burials, in order to explore aspects of childhood palaeohealth. The methodology includes combining various measures of health-including palaeodemography (childhood mortality), analysis of oral health (Early Childhood Caries or ECC), and analysis of physiological health (Cribra Orbitalia and LEH)-with studies of culturally defined mortuary practices to suggest that, while children clearly had significant health deficiencies and many suffered early deaths, their treatment in mortuary rites shows significant economic value and social esteem placed on children. KEYWORDS: Viet Nam, Neolithic, childhood, health, mortuary behavior, palaeodemography, bioarchaeology

Knowledge and attitudes about research ethics among social researchers in Vietnam: A cross-sectional study

Social research has attracted significant attention in Vietnam during recent years with more questions and discussions about how to promote the research outputs and publications in this area. However, there is limited information about the knowledge and attitudes of social researchers for research ethics in Vietnam. This paper aims to assess the knowledge and attitudes of social researchers about research ethics in Vietnam. A survey with 1200 questionnaires, through convenience sampling, was sent either printed copies or email to social researchers in the universities and research institutions in Vietnam. Our response rate was 65% (782), with mean age: 35.9 years (sd=.307). The results show that around one fifth had been trained with research ethics (23.5%), which led to significant responses to the "do not know" about the research ethics principles and research ethics committee with 14.3% and 55.3%, respectively. Despite such few experiences on the research ethics, the participants presented a positive understanding of the general principles of research ethics and positive attitudes to the importance of the related general ethics principles to social research in Vietnam. Such understandings and attitudes also led to the readiness to apply the research ethics values and principles while there are no formal ethical guidelines in Vietnam social research. These findings suggest that Vietnamese social researchers understood most critical ethics principles in social research and expect formal ethical guidelines

FACTORS AFFECTING SUPPLY CHAIN COOPERATION: A CASE-BASED STUDY IN THE ORGANIC AGRICULTURE INDUSTRY IN HANOI, VIETNAM

Purpose: After the covid 19 pandemic, cooperation has become increasingly necessary and important for the supply chain, especially the organic agricultural supply chain, which has loose and fragmented links. Furthermore, with the need for clean, safe food, organic agriculture is also receiving more attention from the government, consumers and businesses. This study aims to examine factors affecting supply chain cooperation based on a survey sample of 120 managers from businesses in the organic agricultural supply chain in Hanoi, Vietnam. From this analysis, we provide solutions to promote cooperation in the supply chain for the organic agriculture industry in Hanoi, Vietnam.   Design/Methodology/Approach: This article uses the research method of analyzing and synthesizing theories about cooperation in the supply chain, thereby providing a research model. Then we use quantitative methods, exploiting the random approach to analyze factors affecting cooperation in the organic agricultural supply chain through surveying subjects that involved in organic agricultural supply chains in Hanoi, Vietnam.   Findings: The research results describe the impact of factors affecting cooperation in the supply chain, showing the level of influence of these factors on cooperation. Through the level of impact, the authors propose solutions to enhance cooperation in the organic agricultural supply chain.   Originality/Value: To the author's knowledge, this study is original in describing the impacts of factors affecting the cooperation of organic agricultural supply chains in Hanoi, Vietnam. Furthermore, the article uses random approaches, contributing to research through a practical lens
