Development of the Optimal Logistics System for Organic Recycling

Abstract Along with the socio-economic development, the generation of solid waste in Vietnam is increasing, becoming an environmental problem. The amount of domestic solid waste generated in Vietnam is currently about 25.5 million tons/year, and is expected to increase on average by 10-15% per year due to rapid population growth, combined with the process of industrialization and urbanization. However, the collection and treatment system of solid waste is still a dilemma. Domestic solid waste management is still treated in traditional ways such as incineration and landfill, causing many harms to the environment. The Optimal Logistic System for Organic Recycling study aims to develop an IoT integrated Logistics system, called LogiOT system, to promote the circular economy model in Vietnam, and proposes a plan to combine waste segregation and utilization of domestic organic wastes as food for worm farming sites to produce organic fertilizers, will reduce CO2 emissions in greenhouse gas emission, contributing to the promotion of model development Circular economy in Vietnam helps to make the environment greener and cleaner. In addition, the logistics model is proposed to solve the problem of the collection system of waste from households, as well as the distribution of organic solid waste to worm farms and distribution of organic fertilizers to the vegetable gardens appropriately, optimizing the cost of the transportation as well as balancing the amount of organic solid waste distributed and the amount required by the garden owners and the amount of solid waste discharged.

Conspectus of effectiveness of the jasper model in developing symbolic play skills for children with autism spectrum disorders

This study provides an overview of 20 research articles from international databases (PubMed, Scholar, Eric, and APA) assessing the effectiveness of the JASPER model in developing symbolic play skills among children with autism spectrum disorders (ASD). The researchers reviewed studies to examine the impact of the JASPER model on the frequency, diversity, and level of symbolic play skills in children with ASD. Results indicate that the JASPER model effectively increases symbolic play skills among children with ASD, enhancing their play experience quality. The application of the JASPER model in developing symbolic play skills for children with ASD in Vietnam shows promise. However, considering differences in intervention services and cultural contexts, recommendations are provided for adapting the JASPER model for effective implementation in Vietnam. This includes cultural adjustments and modifications to intervention protocols. Collaborative efforts between researchers, practitioners, and policymakers are crucial for the successful implementation and dissemination of the JASPER model in Vietnam, potentially improving outcomes for children with ASD in the country.

Economic effects of a controlled mangrove-to-pond coverage ratio policy on mangrove conservation and shrimp farming: A case study in vietnam using instrumental regression analysis

The mangrove-shrimp farming model in Vietnam's Mekong Delta region was devised to foster mangrove conservation while supporting the livelihoods of small-scale shrimp farmers by allocating them land for both mangrove protection and shrimp farming. However, this model faces challenges as farmers often clear mangrove areas to expand shrimp ponds, seeking greater profits. Based on data collected from structured interviews with shrimp farming households, an Instrumental Variable (IV) regression method is used in this study to examine the economic viability of mangrove-shrimp farming in the Tam Giang Protection Forest of Ca Mau province and predict the impacts of recommended fixed mangrove-to-pond coverage ratios (MPR) on shrimp yield and household income in two different scenarios. Findings reveal that almost half of the surveyed farmers do not meet the recommended MPR, prioritizing pond expansion over mangrove protection, suggesting prevalent noncompliance and ineffective regulatory enforcement. Additionally, the research highlighted the critical role of mangrove-shrimp farming in the livelihoods of these communities, with findings indicating that even minimal increases in pond area can enhance productivity. Conversely, stricter pond coverage regulations could potentially worsen the economic situation for numerous households.

Strengthening primary health care through integration of non-communicable disease services: Insights from the abundant health model in Vietnam

ABSTRACT Vietnam is aging rapidly, leading to a substantial rise in morbidity and mortality associated with non-communicable diseases (NCDs). Despite the Government’s 2015 NCD care and management guidelines, there was no practical implementation. From 2018 to 2020, the Abundant Health (AH) model was introduced to enhance the screening and management of hypertension and diabetes at community health stations (CHSs). This study explores the potential for scaling up this model to other provinces in Vietnam and identifying structural enabling factors and challenges based on the model’s lessons learned. The study was conducted in five provinces of Vietnam, using a mixed methods approach of desk review, focus group discussions, key informant interviews, and a survey. Intervention feasibility and acceptability were evaluated using the framework developed by Gadke et al., with a scale of 5 points indicating the highest rating for upscaling the AH model. The sample comprised 164 healthcare providers, 5 group discussions, and 14 focus group discussions. The overall statistical value for Cronbach’s alpha was 0.87, the factor analysis identified 4 factors, and the scale is appropriate for evaluation. The AH model received high average scores for relevance (4.25 over 3 items) and acceptability (4.24 over 4 items). However, feasibility (including suitability and affordability) obtained a lower score (3.65 over 7 items), with primary concerns regarding the availability of local funding for activities (3.04) and the adequacy of equipment and medicines at CHSs (3.08). Enabling factors for delivering quality NCD services at the primary level included strong government commitment to NCD management at the grassroots health level and high community demand for quality NCD management and continuum services. The most significant barriers identified were the scarcity of physicians at CHSs and high staff turnover. The AH model, which encompasses screening, management, and treatment of hypertension and diabetes at CHSs, has demonstrated feasibility and potential for upscaling in Vietnam. Moreover, this model can be adopted in other low- and middle-income countries.

CDIO-based teaching at universities: A case study for students majoring in electrical and electronic engineering technology, Vietnam

In the 1980s of the twentieth century, universities in developed countries began to realize the growing gap between the capabilities of new graduate engineers and the actual requirements of engineering branches. The strong progress of technology requires engineers to have the intellectual abilities and necessary job-specific skills to master that progress. This paper focuses on Conceive, Design, Implement and Operate (CDIO) approach-based teaching for students majoring in electrical and electronic engineering technology at engineering universities in Vietnam to demonstrate the feasibility of the teaching model. The experimental method of synthesizing qualitative and quantitative results for 90 students in control and experimental classes was used. The experimental and control classes both had 45 students. SPSS software version 22 was used to gather data and evaluate the learning results of the two experimental and control groups. According to the findings of the T-test analysis of the independent variables for the two groups, the experimental class performed better in academics and had students in the experimental group who were more satisfied with their post-test scores. This result contributes to confirm that the use of the CDIO-based teaching model in Vietnam is effective for students majoring in electrical and electronic engineering technology.

Instructor positioning as participants in a transnational EMI program

Abstract The simultaneous global growth in higher education’s student population and demand for English-medium instruction (EMI) have created various models of transnational education (TNE) partnerships that use EMI to recruit students and increase opportunities for international collaboration. Inevitably, in transnational collaborative efforts, stakeholders have far more conflicting considerations as they navigate multiple countries’ academic policies and norms, diverse student, staff and faculty expectations, and the myriad of linguistic and cultural differences. In response to these concerns, this qualitative case study analyzed instructor discursive positioning in a TNE partnership between a US and a Vietnamese institution. Using a collaborative action research approach, this article features the experience of two instructors teaching in a TNE partnership using an EMI model in Vietnam. Using identity and positioning theory as guiding theoretical frameworks, instructors’ and students’ discourses were thematically analyzed. The findings reflect dominant discourses and language ideologies surrounding the “Englishization” of higher education, in addition to highlighting stakeholders’ challenges of working between two institutions and having conflicting responsibilities as both instructors and administrative staff. Similarly, the students’ interview data reflected their navigation of being participants at two universities with different academic systems and norms.

SCHOOL CONSULTATION MODEL IN VIETNAM

The school consultation model in Vietnam currently being implemented according to Circular No. 31/2017/TT-BGDDT effective from February 2, 2018, is the “Part-time teacher” model. The purpose of this exploratory study is to test the awareness of officials and teachers about the effectiveness of elements in the “part-time teacher” school consultation model in high schools in Ho Chi Minh City, Vietnam. The research sample was randomly selected from 4 high school heads and from teacher pedagogical training courses and management training classes, with 538 participants, of which teachers (69.0%), and managers (31.0%); in the study sample, there were (36.2%) participating in the school’s psychology team. Research subjects (28.6%) were trained in psychological consultation capacity by topic; (8.9%) training in psychological counseling capacity and granting training certificates; (5.4%) training for bachelor of psychology and master of psychology; (57.1%) had not studied through the psychological counseling competency program. The instrument’s validity and reliability were verified through the evaluation of Cronbach alpha analysis, and exploratory factor analysis (EFA). When analyzing the EFA factor, the results of the factors in the model have a positive correlation of 76.2% (R2 = 1.00), in the factors of personnel conducting consultations, policies for personnel participating in consultations, and policies for consulting personnel. Joining the school counseling team, the consultation process and the consultation room have not been paying attention.

Early safety and mid-term clinical outcomes of technology transfer of transcatheter aortic valve implantation in patients with severe aortic valve stenosis in Vietnam: a single-center experience of 90 patients

This study investigated the early safety and mid-term outcomes of stepwise implementation of transcatheter aortic valve implantation (TAVI) in Vietnamese patients with severe aortic stenosis (AS) at a single center, following the process of technical transfer. From 2017 to 2022, 90 patients with symptomatic severe AS underwent TAVI at a tertiary hospital in Vietnam. The first 30 cases received support for technology transfer from international proctors. One-year outcomes were evaluated using the Valve Academic Research Consortium-2 (VARC-2) criteria. Forty patients (45.5%) had bicuspid aortic valve (BAV). The Medtronic Evolut R/Pro self-expanding valve system was used in 98.9% of all cases, with a 29-mm valve being the most common. Device success was achieved in 95.6% of cases, whereas one procedural death occurred. At one year, four deaths (5.3%) occurred and all were in the BAV group. Other complications included stroke (2.8%), hospital readmission due to the valve or worsening heart failure (2.8%), permanent pacemaker implantation (9.9%), and moderate paravalvular leak (3.0%). The left ventricular ejection fraction and mean transvalvular gradient significantly improved after TAVI. There were no significant differences in procedural success and mortality when the proctor support period and the subsequent solo operator period were compared. TAVI procedure is safe for treating severe AS in Vietnamese patients, despite the high prevalence of BAV. The procedural complication rate was low, with promising outcomes at one year. These results also highlight the effectiveness of the TAVI technical transfer model in Vietnam. No funding was provided for this study.

The value and growth effect in the Vietnamese stock market: a mispricing explanation

PurposeAlthough the value effect is comprehensively investigated in developed markets, the number of studies examining the Vietnamese stock market is limited. Hence, the first aim of this research is to provide empirical evidence regarding returns on value and growth stocks in Vietnam. The second aim is to explain abnormal returns on Vietnamese growth and value stocks using both risk-based and behavioral points of view.Design/methodology/approachFrom the risk-based explanation, the Capital Asset Pricing Model (CAPM), Fama–French three- and five-factor models are estimated. From the behavioral explanation, to construct the mispricing factor, this paper relies on the method of Rhodes-Kropf et al. (2005), one of the most popular mispricing estimations in the financial literature with numerous citations (Jaffe et al., 2020).FindingsWhile the CAPM and Fama–French multifactor models cannot capture returns on growth and value stocks, a three-factor model with the mispricing factor has done an excellent job in explaining their returns. Three out of four Fama–French mimic factors do not contain additional information on expected returns. Their risk premiums are also statistically insignificant according to the Fama–MacBeth second-stage regression. By contrast, both robustness tests prove the explanatory power of a three-factor model with mispricing. Taken together, mispricing plays an essential role in explaining returns on Vietnamese growth and value stocks, consistent with the behavioral point of view.Originality/valueThere are several value-enhancing aspects in the field of market finance. First, this paper contributes to the literature of value effect in emerging markets. While the evidence of value effect is obvious in numerous developed as well as international markets, both growth and value effects are discovered in Vietnam. Second, the explanatory power of Fama–French multifactor models is evaluated in the Vietnamese context. Finally, to the best of the author's knowledge, this is the first paper that incorporates the mispricing estimation of Rhodes-Kropf et al. (2005) into the asset pricing model in Vietnam.

Some Solutions to Promote the Circular Economy toward Sustainable Development in Vietnam

The recent global economic growth has reached many significant milestones, however, there is a problem with natural resources shortage and increasing environmental pollution. Circular economic development has become an international trend, especially when the world’s resources are increasingly exhausted, helping to solve the conflict between economic and environmental interests. In the context of international economic integration, Vietnam has signed a lot of new-generation free trade agreements (FTAs) with different countries and economic sectors, including commitments on environmental protection. Hence, adopting the circular economic model in Vietnam is inevitable to achieve sustainable development.

Modeling quality of life of Ho Chi Minh City dwellers

Quality of life (QoL) has received more and more attention from scholars and researchers from various fields such as healthcare, philosophy, psychology, sociology, and especially economics after many decades of focusing on income. However, researchers have faced many challenges to gain the proper measurement of QoL due to the contextually based concept. This study employs the primary data conducted in Ho Chi Minh City including 500 observations in 2022, with the application of partial least squares structural equation modeling (PLS-SEM) to construct a hierarchical model to measure the QoL of the dwellers in Ho Chi Minh City. The empirical model supports the multi-level hierarchical structure of the QoL. The statistically significant contribution of economic, social, and environmental dimensions in the integrated index has been confirmed. The environmental component shares the highest weight, followed by the economic factor. The social aspect contributes the least share in the quality- of-life index. Further analysis of the sub-criteria in each dimension has been made. The findings implicitly suggest the policy concentration on sustainable factors enhancement to raise the QoL. It was a milestone for policy makers to switch the focus from material to non-material factors in the life quality model in Vietnam.

Tourists’ Perception and Influence Factors in Virtual Tourism Using Bayesian Sentimental Analysis Model in Vietnam Based on e WOM for Sustainable Development

Objective: The advancement of Internet technology brought up the tourism industry towards new development and opportunities. With application of the Internet technology tourism industry comprises a vast range of virtual communities such as Trip Advisor, Agoda, Travelocity and so on. Existing research concentrated on evaluating the factors influencing virtual communities’ behaviour with limited evaluation of tourist perception. This paper focused on examining the tourists' perception of a virtual tour through the sentimental analysis model based on eWOM for sustainable development. Method: The developed model comprises the group average Bayesian network with the computation of the polarity of the tourist perception. A Bayesian network is a data-driven method involved in estimating dependence among the variable with probabilistic computation. Results: The analysis is based on data collected from sample population in Vietnam with consideration of the 11 variables. Participation intensity, social identity, functional value, emotional value, sharing, interaction, and user satisfaction are among eleven primary variables that have been chosen. Conclusions: The analysis of the results expressed that the user satisfaction level is based on the user's experience and functional value. Additionally, the analysis stated that social value comprises the intermediary role in virtual tourism. This research adds to research methodologies of user engagement methods as well as serves as a reference for theoretical research and management practise in the virtual tourist community.

Application of the M-Score Model to Test the Reliability of Financial Statements at Companies Listed on the Vietnamese Stock Market

The reliability of financial statements is important to many people such as investors, corporate shareholders, and auditors. A reliable financial report is free from problems of fraud and manipulation by corporate management. Using the methodology and meta-analysis, the research team found that the application of the M-score model in Vietnam is not yet popular. The number of research papers on the M-score model is small and there is no research using this model to assess the reliability of financial statements. Research results with actual data from the unaudited financial statements of a typical enterprise show that the application of the M-score model to assess the reliability or detect fraud of financial statements is an appropriate fit. However, the research team also found that the M-score model also has a high probability of incorrect identification of unreliable financial statements. Therefore, from the research results, we recommend that investors, shareholders, and stakeholders use a combination of the M-score model together with other technical analysis tools to be able to identify whether a financial statement is reliable.

The implementation of community-based programs in Vietnam is promising in promoting health.

Low-and middle-income countries mostly have ageing populations with many unmet economic, social, or health-related needs, Vietnam being an example. Community-based support in Vietnam, organized as Intergenerational Self-Help Clubs (ISHCs) based on the Older People Associations (OPA) model, can help to meet these needs by the provision of services for various aspects of life. This study aims to assess the implementation of the ISHCs and whether successful implementation is associated with more member-reported positive health. We used the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework to evaluate the implementation using multiple data sources: ISHC board surveys (n = 97), ISHC member surveys (n = 5,080 in 2019 and n = 5,555 in 2020), focus group discussions (6; n = 44), and interviews with members and board leaders (n = 4). Reach ranged between 46 and 83% of ISHCs reaching target groups, with a majority of women and older people participating. Regarding Effectiveness, members indicated high satisfaction with the ISHCs. Adoption scores were high, with 74%-99% for healthcare and community support activities, and in 2019, higher adoption scores were associated with more members reporting good positive health. In 2020, reported positive health slightly decreased, probably due to the influence of the COVID-19 pandemic. A total of 61 ISHCs had consistent or improving Implementation from 2019 to 2020, and confidence in Maintenance was high. The implementation of the OPA model in Vietnam is promising regarding its promotion of health and may help to tackle the needs of an ageing population. This study further shows that the RE-AIM framework helps to assess community health promotion approaches.

Examining financial distress of the Vietnamese listed firms using accounting-based models.

Financial distress is generally considered the most severe consequence for firms with poor financial performance. The emergence of the Covid-19 pandemic has adversely impacted the global business system and exacerbated the number of financially distressed firms in many countries. Only firms with strong financial fundamentals can survive extreme events such as the Covid-19 pandemic and the ongoing Russia-Ukraine conflict. Vietnam is no exception. However, studies examining financial distress using accounting-based indicators, particularly at the industry level, have largely been ignored in the Vietnamese context, particularly with the emergence of the Covid-19 pandemic. This study, therefore, comprehensively examines financial distress for 500 Vietnamese listed firms during the 2012-2021 period. Our study uses interest coverage and times-interest-earned ratios to proxy a firm's financial distress. First, our findings confirm the validity of Altman's Z"- score model in Vietnam only when the interest coverage ratio is used as a proxy for financial distress. Second, our empirical findings indicate that only four financial ratios, including EBIT/Total Assets, Net Income/Total Assets, Total Liabilities/Total Assets, and Total Equity/Total Liabilities, can be used in predicting financial distress in Vietnam. Third, our analysis at the industry level indicates that the "Construction & Real Estates" industry, a significant contributor to the national economy, exhibits the most significant risk exposure, particularly during the Covid-19 pandemic. Policy implications have emerged based on the findings from this study.

Factors Influencing the Auditor Independence and Affects to Audit Quality of Supreme Audit Institution of Vietnam

Purpose: The aim of this study is to explore the factors affect to auditor independence, and impacts auditor independence to audit quality of Supreme Audit Institution (SAI). Theoretical framework: This study explores factors affecting the auditor independence in public sector based on articles pertaining to public sector audits that were published in major publications in the 20th century. The theories were applied in order to build up research model about factors influencing the auditor independence and affects to SAI’s audit quality. Design/methodology/approach: Research using complex techniques to analyze complex relationships in the SEM model. This result tests research model in Vietnam from the perspective of the state auditors’ perception with 225 valid responses. Findings: The result found out three primary factors that affect the independence of public-sector auditors: political hegemony, auditor tenure and relationships with auditees. These factors have negative impact on state auditor’s independence, meanwhile auditor independence has a positive impact on SAI’s audit quality. Research, Practical & Social implications: The study contributes to existing literature by providing empirical evidence for there is no suitable audit quality measurement framework for SAIs. Originality/value: The results highlight strong importance of the auditor independence so that SAI Vietnam can have effective solutions to protect independence of state auditor from threats and improve the audit quality of SAI.

Investigating the course of the ‘Innovation and Opening Up’ model in Vietnam

After the reunification of Vietnam in 1976, and facing difficulties and problems with its economy, the Vietnamese government implemented a series of measures to revitalize the national economy. Since 1986, when it adopted a formal market-oriented policy of ‘innovation and opening up’, this poor agricultural country rapidly transformed into a lower-middle income country. During the reform process, Vietnam’s economy grew steadily and people’s livelihoods improved significantly. Around Vietnam’s economic success in this article, from the industrial structure, opening to the outside world and economic development level three aspects carries on the model, found that Vietnam’s economic development and changes and other southeast Asian developing countries, there is no greater degree of different, however, Vietnam ‘open innovation’ evolution of beneficial experience of significance of reference to the development of developing countries.

Modeling the Quality of Urban Life using Grey Analytical Hierarchy Process

Economic growth has recently been crowded out by life quality in the new development pattern. Unlike the income-based measurement of economic growth, the life quality measure has become a challenge because it is a multi-dimensional concept that relies on the subjective evaluation of the involved stakeholders in a particular context. The objective of this study was to investigate the model of quality of urban life in Ho Chi Minh City, Vietnam based on subjective indicators. The word clouds and grey analytical hierarchy process were employed to analyze the data from thirty in-depth interviews with experts in the field. The empirical model of quality of urban life in Ho Chi Minh City was found with three levels. The ranking results at the second level emphasized the high shares of health, employment, and income compared to self-esteem, socialization, and family happiness. The ranking results at the second level emphasized the high shares of health, employment, and income compared to self-esteem, socialization, and family happiness. Further investigation at the third level has confirmed the superiority of non-material components in the quality of urban life model in Ho Chi Minh City, Vietnam. The findings were critical in implying the policy concentration on non-material values enhancement to raise the quality level of urban life. It was a milestone in switching the focus from material to non-material factors in the life quality model in Vietnam.
