The study of cultural evolution has taken on an increasingly interdisciplinary and diverse approach in explicating phenomena of cultural transmission and adoptions. Inspired by this computational movement, this study uses Bayesian networks analysis, combining both the frequentist and the Hamiltonian Markov chain Monte Carlo (MCMC) approach, to investigate the highly representative elements in the cultural evolution of a Vietnamese city’s architecture in the early 20th century. With a focus on the façade design of 68 old houses in Hanoi’s Old (...) Quarter (based on 78 data lines extracted from 248 photos), the study argues that it is plausible to look at the aesthetics, architecture, and designs of the house façade to find traces of cultural evolution in Vietnam, which went through more than six decades of French colonization and centuries of sociocultural influence from China. The in-depth technical analysis, though refuting the presumed model on the probabilistic dependency among the variables, yields several results, the most notable of which is the strong influence of Buddhism over the decorations of the house façade. Particularly, in the top 5 networks with the best Bayesian Information Criterion (BIC) scores and p<0.05, the variable for decorations (DC) always has a direct probabilistic dependency on the variable B for Buddhism. The paper then checks the robustness of these models using Hamiltonian MCMC method and find the posterior distributions of the models’ coefficients all satisfy the technical requirement. Finally, this study suggests integrating Bayesian statistics in the social sciences in general and for the study of cultural evolution and architectural transformation in particular. (shrink)

And not just look; one needs to know where to look as well. In this case: look upwards, on the second floor of the old townhouses, which has not been replaced by showcasing pavilions or modern glass doors. Some houses have been repainted, but the architecture – the form of the story, the shapes, and construction of the balconies, the decorating sculptures – still exudes a century-old familiarity. So it turns out that Phố Phái, though no longer intact, is still (...) present here. (shrink)

Expeditious increase in population and industrialization has led to alarming rates of air pollution in all countries. However, developing economies have had to face a more adverse and severe impact. This had led to many changes in the day to day living of citizens. In this paper we have focused on the psychological process and predictors of migration intention of the people living in Hanoi, Vietnam. Two stratified random datasets of 475 people were used, and Bayesian analysis was performed (...) on this dataset. We found out that the intent to move was negatively associated to the individual’s satisfaction with air quality. We also found that people who have family members that have fallen victim to a disease caused by air pollution are more likely to migrate. This paper discusses an important topic: immigration of the younger demographic, i.e. the Hanoi workforce, which may cause restrictions and hurdles in the city's urbanisation and development. The findings suggest that, if measures against air pollution are not taken, economic forces may be disrupted, posing a threat to urban growth. As a result, collaborative activities and steps need to be taken by the government to curb this unfortunate consequence. (shrink)

Hanoi – the capital city of Vietnam and the land of thousand years of civilization – invokes among both locals and tourists the image of the ‘Sword Lake’ with its ancient ‘Turtle Tower’ and the charming Old Quarter with its preserved old houses lying along small commercial alleys. The houses in the Old Quarter were constructed over a century ago which feature tube houses with inclined tile roofs and a blend of French architecture create the infusions of history and (...) memory. Researchers of various fields have attempted to capture and explain the essence of these townhouses in their works, either in the collectibles of many authors, the quintessential drawings of talented painters, or in publications on the history of the Old Quarter. Among these, the recent work by Vuong et al. (2019) adds a unique view of the architectural features of Hanoi’s ancient townhouses as these features are viewed as dependent and independent variables. The study titled ‘Cultural evolution in Vietnam’s early 20th century: A Bayesian network analysis of Hanoi Franco-Chinese house designs’ aims to find traces of cultural evolution in the early 20th century in Vietnam and highlight the most notable elements that affect the Vietnamese people’s perception of cultural evolutions.

Air pollution is a considerable environmental stressor for urban residents in developing countries. Perceived health risks of air pollution might induce migration intention among inhabitants. The current study employed the Bayesian Mindsponge Framework (BMF) to investigate the rationale behind the domestic and international migration intentions among 475 inhabitants in Hanoi, Vietnam – one of the most polluted capital cities worldwide. We found that people perceiving more impacts of air pollution in their daily life are more likely to have migration (...) intention. The effect of perceived air pollution impact on international migration intention is stronger than that of domestic migration. Acknowledging a family member’s air pollution-induced sickness moderated the association between perceived air pollution impact and domestic migration intention, while the personal experience of air pollution-induced sickness did not. In contrast, the moderation effect of personal experience of sickness became significant in the international migration circumstance, but the effect of information about a family member’s sickness was trivial. The findings suggest that urban inhabitants’ consideration of air pollution averting strategies reflects some characteristics of Homo Oeconomicus. Additionally, the individual’s socio-economic decision is seemingly insignificant on a social scale. Still, through environmental stressors as catalysts, such decisions might result in considerable social outcomes (e.g., internal migration and emigration). (shrink)

Decision-making regarding healthcare expenditure hinges heavily on an individual's health status and the certainty about the future. This study uses data on propensity of general health exam (GHE) spending to show that despite the debate on the necessity of GHE, its objective is clear—to obtain more information and certainty about one’s health so as to minimise future risks. Most studies on this topic, however, focus only on factors associated with GHE uptake and overlook the shifts in behaviours and attitudes regarding (...) different levels of cost. To fill the gap, this study analyses a dataset of 2068 subjects collected from Hanoi (Vietnam) and its vicinities using the baseline-category logit method. We evaluate the sensitivity of Vietnamese healthcare consumers against two groups of factors (demographic and socioeconomic-cognitive) regarding payment for periodic GHE, which is not covered by insurance. Our study shows that uninsured, married and employed individuals are less sensitive to cost than their counterparts because they value the information in reducing future health uncertainty. The empirical results challenge the objections to periodic health screening by highlighting its utility. The relevance of behavioural economics is further highlighted through a look at the bounded rationality of healthcare consumers and private insurance companies in using and providing the service, respectively.

Following is the skin left on the bark of an old tree on a Hanoi street, after a cicada molted and flew up on somewhere nearby. This cicada grew mature much later than its peers since the cicada orchestra stopped playing the music already in late June. We could hardly hear its song due to the noises of a busy road in a densely populated city like Hanoi. But as we all know, the cicada just did what it (...) was supposed to. It would just fly up to some stem nearby and sing the song, even though it is not sure if there’s any audience left. Today, after typhoon Yagi, our preprint titled “Further on informational quanta, interactions, and entropy under the granular view of value formation” did the same thing. Being accepted to be published in The VMOST Journal of Social Sciences and Humanities, the manuscript was shedding its old “skin” to fly and started singing its own song. The paper presents an enlarged definition of value and the information interaction mechanism underlying the forming of a new value. Thus, it manifests an advance of mindsponge theory with the help of quantum physics and information theory. (shrink)

Depressive disorders have been found to be a significant health issue among industrial workers, resulting from work-related factors and causing serious burdens for the workers as well as their employers. Literature on mental health problems of Vietnamese industrial workers has been limited, despite the rapid foreign investment-fueled industrialization process of the country. This study aimed to fill the gap in literature by examining the prevalence of depressive disorders and their potential associated factors among a cohort of Vietnamese industrial workers. A (...) cross-sectional study was conducted in 3 industrial areas in Hanoi and Bac Ninh. A total of 289 workers agreed to participate in the study. Generalized linear mixed models were applied to identify associated factors with depression status of respondents. 38.6% of participants reported suffering depression. Factors found to be positively associated with the possibility of having depression and higher PHQ9 score were long working hours, suffering more health problems, and health hazards exposure at work. Meanwhile, being females, having more children, living with parents, engaging in smoking, and being local workers were found to correlate with lower likelihood of being depressed. The findings suggested the importance of regular health screening, work safety assurance, and social support outside of workplace on the mental health of the workers. (shrink)

The article entitled “Cultural evolution in Vietnam’s early 20th century: A Bayesian networks analysis of Hanoi Franco-Chinese house designs” investigates how diverse cultures and religious creeds influenced the architecture of Hanoi in the early 20th century.

In Vietnam, regionalisation in the GMS occurs in different parts at different paces and levels driven by the central government and with the participation of the local governments, private sector and grassroots people in the framework of the GMS Program. So far there has been no major research either in Vietnamese or English that addresses this issue. The thesis seeks to fill this gap by examining the empirical process of regionalisation in three Vietnam’s border towns in the First-Generation GMS Economic (...) Corridor Town Development Project. Employing analytical framework based on relevant International Relations and interdisciplinary theories, and a mix of qualitative and quantitative methods, the thesis finds that the GMS regionalisation is a combination of ‘top-down’ and ‘bottom-up’ processes. The thesis commences by highlighting the significance of the Mekong River to the development of the region. Then various multilateral cooperative schemes are explored to generate a complete picture of regional cooperation. It is concluded that many multilateral mechanisms with little progress may have negative impacts on the regionalisation in the GMS. Among 13 schemes in the GMS, GMS Program is considered as one of the most well-known subregional cooperation schemes. The GMS Program came to existence just in time to assist the Mekong riparian states to integrate better into the regional and international markets in the context that there were new developments both at the regional and world’s levels. In the case of Vietnam, the GMS Program has given Hanoi an option to carry on its omni-directional foreign policy and helped it consolidate its existing relationships with its traditional and neighbouring partners. Notably, regionalisation is occurring in some parts of the country where GMS projects have been implemented. Regionalisation can be best observed in economic space where there are intensive interactions among people under various dimensions enabled by favourable policies. Although regionalisation promises to bring new cooperative opportunities in the GMS, regionalisation in the GMS will continue to meet new challenges from growing natural and man-made threats to the Mekong River. Further, the involvement of outsiders is also a real challenge to the regionbuilding process. (shrink)
