Some conditions are given to ensure that for a jump homogeneous Markov process $\{X(t),t\ge 0\}$ the law of the integral functional of the process $T^{-1/2} \int^T_0\varphi(X(t))dt$ converges to the normal law $N(0,\sigma^2)$ as $T\to \infty$, where $\varphi$ is a mapping from the state space $E$ into $\bbfR$.

Nowadays, the power systems are getting more and more complicated because of the delays introduced by the communication networks. The existence of the delays usually leads to the degradation and/or instability of power system performance. On account of this point, the traditional load frequency control approach for power system sketches a destabilizing impact and an unacceptable system performance. Therefore, this paper proposes a new LFC based on adaptive integral second-order sliding mode control approach for the large-scale power system with communication (...) delays. First, a new linear matrix inequality is derived to ensure the stability of whole power systems using Lyapunov stability theory. Second, an AISOSMC law is designed to ensure the finite time reachability of the system states. To the best of our knowledge, this is the first time the AISOSMC is designed for LFC of the LSPSwCD. In addition, the report of testing results presents that the suggested LFC based on AISOSMC can not only decrease effectively the frequency variation but also make successfully less in mount of power oscillation/fluctuation in tie-line exchange.

Despite increasing scholarly interest in tertiary student perceptions of plagiarism, very little is known about those held by postgraduate students, although differences between undergraduate and PG students relate to both their characteristics and the demands of their studies. Furthermore, there is a dearth of research within the context of international education, where managing plagiarism is seen as a major challenge. This paper reports on a recent online survey with 207 Vietnamese and local PG students at a New Zealand university regarding (...) their perceptions of plagiarism. The findings showed significant differences both between and within the two groups. Perception variations arose from a range of influences and prior experiences, not just the culture in which the students were initially educated. Differences related to participants’ age, gender, academic levels, disciplines, and teaching experience. This study’s findings contribute knowledge about under-researched PG students and problematize prevalent stereotypes of international students regarding plagiarism. They generate implications for higher education institutions to accommodate international and domestic PG student needs in ways that respect their diversities in detail as individuals, not as members of a homogeneous group. Further qualitative research to explore PG student perceptions in greater depth is recommended. (shrink)

This paper endeavors to understand the research landscape of finance research in Vietnam during the period 2008 to 2020 and predict the key defining future research directions. Using the comprehensive database of Vietnam’s international publications in social sciences and humanities, we extract a dataset of 314 papers on finance topics in Vietnam from 2008 to 2020. Then, we apply a systematic approach to analyze four important themes: Structural issues, Banking system, Firm issues, and Financial psychology and behavior. Overall, there have (...) been three noticeable trends within finance research in Vietnam: (1) assessment of financial policies or financial regulation, (2) deciphering the correlates of firms’ financial performances, and (3) opportunities and challenges in adopting innovations and ideas from foreign financial market systems. Our analysis identifies several fertile areas for future research, including financial market analysis in the post-COVID-19 eras, fintech, and green finance. (shrink)

Objectives: The official implementation of clinical pharmacy in Vietnam has arrived relatively late, resulting in various stressors. This study aims to evaluate job stress level and suggest viable solutions.Methods: A cross-sectional study was conducted on clinical pharmacists in 128 hospitals in Ho Chi Minh City. Job stress questions were derived from the Healthcare Profession Stress Inventory.Results: A total of 197 CPs participated, giving a response rate of 82.4%. Participants were found to have moderate job stress with an overall mean (...) stress score of 1.5 and stress rate of 52.8%. The sample size was statistically adequate and the HPSI was valid and reliable. Patient care responsibility was the main stressor, especially in public hospitals, followed by job conflicts. Lack of experience, low income, and inability to participate in clinical ward rounds caused significant stress to CPs regarding job recognition and job uncertainty. More practice-oriented training programs in bachelor curricula and clinical practice should be applied to help CPs gain more experience, self-confidence, and diminish job stress.Conclusion: CPs in HCMC have moderate stress. More practice-oriented training programs should be prioritized to lessen stress for CPs. (shrink)

O confucionismo existe, na vida espiritual do povo vietnamita, desde muito tempo. A parte positiva do Confucionismo pode-se dizer que é o fato de ele contribuir para o fortalecimento das relações familiares, entre os parentes, bem como nas relações sociais de um modo geral; outra parte positiva consiste em motivar as pessoas a desenvolverem o gosto pela leitura e aprendizagem. Estima-se que a ética confucionista precisa ser provocada, a fim de contribuir para a construção da sociedade nos dias atuais. Na (...) contramão dessa positividade, pode-se afirmar que o confucionismo, de maneira geral, não valoriza, na medida necessária, o papel das mulheres na sociedade; na realidade, ele as classifica como pessoas insignificantes. É digno de se observar, entretanto, que, no contexto social específico do Vietnã, as mulheres encontram um lugar próprio na sociedade. Nossa pesquisa visa mostrar exatamente essa diferente concepção do papel da mulher na socidade vietnamita. (shrink)

Parental environmental education in early childhood is vital for nurturing environmental awareness and ecological protection. This study investigates how parents’ nature engagement methods influence children’s environmental awareness and participation in protection activities. Using the Bayesian Mindsponge Framework with data from 516 children and their primary caregivers across 23 elementary summer schools in five urban Chinese cities, the findings reveal varying impacts of parental engagement methods. Raising animals and plants is positively associated with environmental awareness (moderate reliability) and protection activities (high (...) reliability). Visiting museums about endangered and extinct species enhances children’s environmental awareness, while learning about insects and their habits improves their participation in protection activities (both high reliability). However, outdoor learning experiences and playing in natural environments (e.g., parks and forests) show ambiguous effects. These results underscore the value of family-centered environmental education, emphasizing the crucial roles of direct nature interactions and providing actionable insights for child-focused environmental policies.

Climate change and biodiversity loss are interconnected crises that demand integrated solutions. While mitigation strategies such as reforestation and afforestation, renewable energy development, and Bioenergy with Carbon Capture and Storage (BECCS) are essential for reducing greenhouse gas emissions, they also pose risks to ecosystems, specifically biodiversity. This review examines the biodiversity impacts of these key mitigation strategies, identifying potential trade-offs and opportunities for synergy. Large-scale forest plantations can sequester carbon but often reduce biodiversity when implemented as monocultures. Renewable energy expansion, (...) particularly wind and solar farms, contributes to decarbonization but can disrupt habitats and wildlife migration. BECCS, though promoted for negative emissions, requires extensive land conversion, threatening biodiversity and food security. To balance climate action with ecological integrity, this study advocates for an eco-surplus culture, where mitigation strategies not only minimize harm but actively enhance biodiversity. Nature-based solutions, such as restoring native forests and integrating biodiversity-conscious renewable energy planning, offer pathways to maximize co-benefits. Policy frameworks must prioritize biodiversity safeguards, promote sustainable land use, and ensure community participation. Addressing climate and biodiversity goals together through holistic, long-term planning is essential for fostering environmental resilience and achieving genuinely sustainable climate solutions.

This research investigates the factors influencing the disparity between domestic gold prices (SJC gold and 9999 gold) and global gold prices in Vietnam from January 2011 to December 2023. Using the Autoregressive Distributed Lag (ARDL) model, we identify key macroeconomic determinants impacting this price spread, including interest rates, oil prices, and consumer demand. Our findings reveal that higher interest rates are associated with larger price spreads, suggesting that monetary policy plays a significant role in the domestic gold market. Oil prices (...) exhibit a negative relationship with the price spread for 9999 gold, indicating that rising oil prices tend to align domestic gold prices more closely with global trends. Consumer demand notably affects the SJC_Global price spread but not the 9999_Global spread, reflecting the different market dynamics of finished goods versus raw materials. Additionally, the error correction terms in both models indicate a robust mechanism for long-term equilibrium, demonstrating the Vietnamese gold market’s resilience. These insights highlight the need for policymakers to reconsider existing regulations, such as Decree 24, to ensure a stable and efficient gold market. The study concludes that while the Vietnamese gold market exhibits sustainable practices, regulatory revisions are necessary to support both market growth and community development. Future research should consider additional macroeconomic variables and the impact of regulatory changes over time to further understand the dynamics of gold price disparities in Vietnam. (shrink)

Background: School meal programs are not only government initiatives but also community-driven efforts. Aiming to combat food insecurity among school-aged children effectively, these programs are executed in conjunction with food bank initiatives. Various community groups play a crucial role in the success of both food security initiatives. There is a need to improve community engagement to successfully link school meal programs with food banks to build program synergy, combating food insecurity through a two-sided approach. Aim: This study aims to examine (...) community engagement in school meals program by analyzing its purposeful focus on creating jobs and income-generating opportunities for different community groups, i.e., youths, women, and others. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge theory and inference advantages of Bayesian analysis, was employed on a dataset of 126 government representatives who manage large-scale school meal programs in 126 different countries. Results: Findings showed that the school meals program’s purposeful focus on creating jobs and income-generating opportunities for women in the community was positively associated with community engagement, thereby supporting the linkage between the programs and food banks. In contrast, providing jobs and income-generating opportunities for youths and other community groups had an ambiguous association with community engagement in school meal programs. Conclusions: Findings underscore the importance of creating jobs and income-generating opportunities for women to improve community engagement in school meal programs. Formulating strategies that empower woman’s entrepreneurship may foster their involvement and engagement in school meal programs, promising to successfully link these programs with food bank initiatives among implementing countries.

Cultural diplomacy is a special form of cultural application to improve diplomatic effectiveness, create, and promote national culture. Since the Cold War until now, South Korea, Japan, and India have been continuously promoting cultural diplomacy based on the dissemination of increasingly interconnected literary and cinematic publications. Cultural diplomacy with Vietnam has also helped South Korea, Japan, and India maximize their role as responsible powers for a typical Southeast Asian country, Vietnam. Through three typical cases in promoting the role of cultural (...) diplomacy to preserve Oriental cultural identity: Japan, India, and South Korea, by using systemic and interdisciplinary methods, the article focuses on four main characteristics that demonstrate the role of cultural diplomacy in preserving Oriental cultural identity in these countries, the quantity, content, implementation situation, and economic - political - social role of cultural products are utilized and promoted in cultural diplomacy of South Korea, Japan, and India. The article shows that cultural diplomacy not only spreads Oriental cultural values, contributing to maintaining economic growth of the Asian countries mentioned in the article, but also helps improve national brand image, enhance the position and national potential in the international stage.

Rapid urbanization in Vietnam significantly impacts the environment and human well-being. Public parks are crucial for enhancing social and environmental sustainability in urban areas, yet their establishment and expansion require substantial funding. This study investigates the factors influencing Vietnamese urban residents’ willingness to donate to planting projects in public parks, utilizing the Bayesian Mindsponge Framework (BMF), which combines Mindsponge Theory’s informational entropy-based notion of value with Bayesian analysis. Analyzing data from 535 residents in major Vietnamese cities, we found that while (...) men visit public parks more frequently, they are less willing to donate to planting projects. Older residents visit parks more often and are more willing to donate, while higher-income individuals show greater willingness to donate. Most motivations—such as relaxation, physical activities, nature enjoyment, socializing, and family time—are positively linked to park visit frequency and indirectly to donation willingness. However, only relaxation and enjoyment of nature are directly associated with willingness to donate. Interestingly, higher education levels and visiting parks for children’s educational activities are associated with lower donation willingness. These findings hint at the possible existence of the free-riding problem, gender inequality, ineffective environmental education, and lack of awareness of public parks’ natural value, as well as opportunities to cultivate an eco-surplus culture through nature interactions in public parks.

This paper investigates the task of reference resolution in the legal domain. This is a new interesting task in Legal Engineering research. The goal is to create a system which can automatically detect references and then extracts their referents. Previous work limits itself to detect and resolve references at the document targets. In this paper, we go a step further in trying to resolve references to sub-document targets. Referents extracted are the smallest fragments of texts in documents, rather than the (...) entire documents that contain the referenced texts. Based on analyzing the characteristics of reference phenomena in legal texts, we propose a four-step framework to deal with the task: mention detection, contextual information extraction, antecedent candidate extraction, and antecedent determination. We also show how machine learning methods can be exploited in each step. The final system achieves 80.06 % in the F1 score for detecting references, 85.61 % accuracy for resolving them, and 67.02 % in the F1 score for the end-to-end setting task on the Japanese National Pension Law corpus.

As a generation of ‘digital natives,’ secondary students who were born from 2002 to 2010 have various approaches to acquiring digital knowledge. Digital literacy and resilience are crucial for them to navigate the digital world as much as the real world; however, these remain under-researched subjects, especially in developing countries. In Vietnam, the education system has put considerable effort into teaching students these skills to promote quality education as part of the United Nations-defined Sustainable Development Goal 4 (SDG4). This issue (...) has proven especially salient amid the COVID−19 pandemic lockdowns, which had obliged most schools to switch to online forms of teaching. This study, which utilizes a dataset of 1061 Vietnamese students taken from the United Nations Educational, Scientific, and Cultural Organization (UNESCO)’s “Digital Kids Asia Pacific (DKAP)” project, employs Bayesian statistics to explore the relationship between the students’ background and their digital abilities. Results show that economic status and parents’ level of education are positively correlated with digital literacy. Students from urban schools have only a slightly higher level of digital literacy than their rural counterparts, suggesting that school location may not be a defining explanatory element in the variation of digital literacy and resilience among Vietnamese students. Students’ digital literacy and, especially resilience, also have associations with their gender. Moreover, as students are digitally literate, they are more likely to be digitally resilient. Following SDG4, i.e., Quality Education, it is advisable for schools, and especially parents, to seriously invest in creating a safe, educational environment to enhance digital literacy among students.

We present our method for tackling a legal case retrieval task by introducing our method of encoding documents by summarizing them into continuous vector space via our phrase scoring framework utilizing deep neural networks. On the other hand, we explore the benefits from combining lexical features and latent features generated with neural networks. Our experiments show that lexical features and latent features generated with neural networks complement each other to improve the retrieval system performance. Furthermore, our experimental results suggest the (...) importance of case summarization in different aspects: using provided summaries and performing encoded summarization. Our approach achieved F1 of 65.6% and 57.6% on the experimental datasets of legal case retrieval tasks. (shrink)

In this paper, we explore the effect of musical expertise on whistled word perception by naive listeners. In whistled words of nontonal languages, vowels are transposed to relatively stable pitches, while consonants are translated into pitch movements or interruptions. Previous behavioral studies have demonstrated that naive listeners can categorize isolated consonants, vowels, and words well over chance. Here, we take an interest in the effect of musical experience on words while focusing on specific phonemes within the context of the word. (...) We consider the role of phoneme position and type and compare the way in which these whistled consonants and vowels contribute to word recognition. Musical experience shows a significant and increasing advantage according to the musical level achieved, which, when further specified according to vowels and consonants, shows stronger advantages for vowels over consonants for all participants with musical experience, and advantages for high‐level musicians over nonmusicians for both consonants and vowels. By specifying high‐level musician skill according to one's musical instrument expertise (piano, violin, flute, or singing), and comparing these instrument groups to expert users of whistled speech, we observe instrument‐specific profiles in the answer patterns. The differentiation of such profiles underlines a resounding advantage for expert whistlers, as well as the role of instrument specificity when considering skills transferred from music to speech. These profiles also highlight differences in phoneme correspondence rates due to the context of the word, especially impacting “acute” consonants (/s/ and /t/), and highlighting the robustness of /i/ and /o/.

Religious beliefs are defined as thinking, feeling and behaving in accordance with the beliefs and teachings of a religious system. In other words, religious beliefs are indicative of the role of religion in the individual and social life of people, as well as adherence to values and beliefs in daily life, performing religious practices and rituals and participating in activities of religious organisations. Religious beliefs are a set of dos and don'ts, and values are considered one of the most important (...) psychological supports that can provide meaning in all moments of life and save a person from meaninglessness by providing explanatory support in specific situations. In addition, work conscience is defined as a feeling of inner commitment to comply with agreed-upon requirements for work. In other words, work conscience means heartfelt satisfaction and practical commitment to the tasks that a person is supposed to perform properly, in a way that there will be no negligence in performing the duty even if no supervisor oversees the activity. Given the significant role of nurses in hospitals, especially during the coronavirus disease 2019 (COVID-19) pandemic, the religious beliefs of healthcare employees have become more important. Therefore, the present study aimed to evaluate the effect of religious beliefs on the work conscience of 1800 Muslim nurses in Iraq during the COVID-19 pandemic in 2021. Standard questionnaires were applied to assess the respondents' religious beliefs and work conscience. In addition, data analyses (Cronbach's alpha, Pearson's correlation, etc.) were performed in Statistical Package for the Social Sciences (SPSS). According to the results, religious beliefs have a positive effect on nurses' work conscience (p = 0.822). CONTRIBUTION: The findings of this study showed that the employees of an organisation, especially nurses and healthcare staff, can rely on their religious beliefs and benefit from their advantages in order to strengthen their work conscience during a hard time such as the COVID-19 pandemic.

We consider structures of the form (Z;+,C), where C is an additive cyclic order on (Z;+). We show that such structures are dp-minimal and in this way produce a continuum-size family of dp-minimal expansions of (Z;+) such that no two members of the family define the same subsets of Z.

Market crises amplify fear, disrupting rational decision-making of stock investment. This study examines the relationship between investors’ information priorities—such as intuition, company performance, technical analysis, and other factors—and their fear responses (freeze, flight, and hiding) during market crashes. Using the Bayesian Mindsponge Framework (BMF) to analyze data from 1,526 investors in China and Vietnam, the findings reveal complex dynamics. We found positive associations between investors’ prioritization of social influence and intuition for investment decision-making with being freeze (i.e., not knowing what (...) to do with the owned stock), between prioritization of professionals’ evaluation and intuition with fleeing (i.e. giving up stock investment permanently), and between prioritization of professionals’ evaluation and social influence with hiding (i.e., stopping investing in stock for a while). In contrast, prioritization of companies’ performance metrics (e.g., net profit, debt, etc.) was negatively associated with being freeze, fleeing, and hiding. Meanwhile, prioritization of professionals’ evaluation, technical analysis, and liquidity was negatively associated with being freeze, fleeing, and hiding, respectively. The study highlights the importance of disseminating transparent, accurate information through government and media channels, along with implementing financial education programs, to promote rational investment decisions and reduce fear-driven behaviors.

Parental influence plays a crucial role in shaping children’s behaviors. While several studies have examined parents’ roles in fostering children’s sustainable habits, they often treat parental influence as a single construct, overlooking the distinct roles of fathers and mothers, as well as the influence of cultural values and norms. This study explores the distinct roles of Chinese fathers and mothers in shaping children’s waste reusing and recycling behaviors. Using Bayesian Mindsponge Framework analytics, the study analyzed responses from 516 children and (...) their corresponding caregivers (either fathers or mothers) from 23 elementary summer schools across five major urban cities in China. The analysis revealed that mothers were central agents of influence, with their recycling behavior and mother-child engagement showing positive and highly reliable associations with children’s waste reusing and recycling practices. The impact of mothers’ recycling behaviors was further amplified by children’s frequency of perceiving their mother’s waste reusing and recycling actions. Meanwhile, fathers’ direct engagement and role modeling (when their actions were frequently perceived by their children) also positively influenced children’s behaviors. Still, these effects were less reliable than those of mothers. These findings suggest that policymakers and educators should design interventions that leverage mothers’ natural role as influencers while actively encouraging greater involvement from fathers in environmental education.

Studying the psychology behind the purchase of eco-friendly products and second-hand items can offer valuable insights to promote sustainable consumer behavior. This paper examines factors influencing Italian consumers’ willingness to pay regarding bio-based clothing and second-hand items. Drawing from data collected from 402 Italian participants, we examine how motivations and socio-demographic factors are associated with willingness to pay in the context of sustainable fashion. Our findings reveal that motivations related to environmental concerns are positively associated with consumers’ willingness to pay (...) higher premiums for bio-based clothing. Higher income and education levels are also associated with the willingness to pay higher premiums. Meanwhile, motivation related to vintage appeal is associated with lower desired discounts for second-hand items, particularly among older consumers. Gender differences also influence discount preferences, with men seeking larger discounts on second-hand clothing compared to women. By providing insights into Italian consumers’ sustainable fashion choices, this study offers implications for businesses, policymakers, and researchers aiming to promote eco-conscious consumption and sustainability in the fashion industry.

The rapidly evolving space tourism industry faces significant challenges in building consumer trust and balancing emotional appeal with factual accuracy—both essential for reducing uncertainty and fostering long-term public engagement in this high-risk sector. This study examines the key factors shaping individuals’ intentions to participate in space tourism, with a focus on their perceived trustworthiness, usefulness, and immersiveness of information on social media. Applying Mindsponge Theory, we explore the interplay between trust evaluation and subjective cost-benefit judegement of individuals in high-risk tourism (...) context. The findings reveal that while trustworthiness positively influences participation intention, its role diminishes when usefulness and immersiveness are particularly strong. This suggests that space tourists, who are naturally inclined toward risk-taking, prioritize experiential rewards—such as novelty, prestige, and emotional engagement—over concerns about information reliability. These insights offer practical implications for marketing in high-risk industries, highlighting the importance of immersive storytelling, exclusivity, and transformative experiences over conventional trust-building measures. Future research should investigate how personal risk tolerance, prior experience, and cognitive biases shape thought processes, decision-making, and behaviors in extreme tourism contexts. (shrink)

This article contributes to the limited literatures on small- and medium-size enterprises and corporate social responsibility. Using an institutional theoretical framework, we analyzed fieldwork interviews with twenty SMEs and perspectives of 165 SME managers and workers in textiles, garment, and footwear industries, the most important wage-earning sector in Vietnam. Having understood in the context of a developing “market economy with socialist orientation”, we find that socially responsible practices and expectations developed long before the arrival of CSR as a western concept (...) and an MNC agenda. While identifying and contributing ideas concerning forms of “informal” CSR practices—influenced by social and cultural expectations—to the CSR/sme literature, we are conscious of the mixed effects of these practices and the ongoing nuanced negotiations between workers and managers in these SMEs. In our research, we found that it takes both domestic and international stakeholders to improve labor conditions in Vietnam under the banner of CSR. (shrink)

Public sentiment regarding climate change in the United States is starkly divided, with the Republicans and Democrats holding markedly different views. Given the inherent connection between the water crisis and climate change, this research aimed to investigate the interplay between the residents’ beliefs about the impact of climate change on water supply unpredictability, their political identity, and their willingness to adopt direct and indirect potable water reuse. The Bayesian Mindsponge Framework (BMF) analytics was conducted on a dataset of 1,831 water (...) users in the arid region of Albuquerque, New Mexico. The findings reveal a complicated interplay among examined factors. Specifically, we discovered a positive association between the belief in the impacts of climate change and the willingness to adopt potable water reuse among non-Republican water users. In contrast, Republican water users exhibit a negative association between climate change belief and willingness to adopt potable water reuse. Interestingly, despite this, Republicans generally show a higher overall willingness to adopt potable water reuse compared to non-Republicans. These findings suggest that contextual factors in Albuquerque, New Mexico, in which challenges of aridity and economic dependence on water resources are pronounced, might be important aspects contributing to the Republican’s high willingness to adopt potable water reuse. Also, the current climate change communication strategy with the Republicans might not be appropriate, and it should be tailored to align with the Republicans’ beliefs and persuade them better.

This study examines the dynamic relationship between face-saving mechanisms—proxied by age, income, and gender—and the peers’ safe-driving information on the driving behaviors of Chinese drivers. Using the Bayesian Mindsponge Framework (BMF) and Granular Interaction Thinking Theory (GITT) to analyze data from 1,039 Chinese drivers, we uncover a complex interplay of factors. Our findings suggest that peers serving as role models and actively supporting careful driving positively influence drivers’ safe driving behaviors. The effect of role-model peers is strengthened among drivers with (...) higher age and income levels. In contrast, the impact of actively engaged peers is lower among these groups and male drivers (though the gender’s negative moderation effect is weakly reliable). These results highlight the crucial role of peer influence in promoting safe driving and underscore the dynamic effects of cultural values, particularly face-saving concerns, on drivers’ cognitive and behavioral processes in China.

This article addresses the problem of automatically extracting legal indices which express the important contents of legal documents. Legal indices are not limited to single-word keywords and compound-word keywords, they are also clause keywords. We approach index extraction using structural information of Japanese sentences, i.e. chunks and clauses. Based on the assumption that legal indices are composed of important tokens from the documents, extracting legal indices is treated as a problem of collecting chunks and clauses that contain as many important (...) tokens as possible. Each token is assigned a weight which is a statistical score, e.g. TF–IDF and Okapi BM25, to indicate its importance. The importance of a chunk or clause is determined based on the average weight of tokens included in that chunk or clause. Then, highly weighted chunks and clauses are recognized as the indices for legal documents. The experimental results on Japanese National Pension Act data show that our proposed method achieves better performance than TextRank, the most popular unsupervised method in extracting single-word and compound-word keywords. In addition, this approach is also applicable to extract clause keywords with high performance. (shrink)

For centuries, fiction—particularly fables—has seamlessly combined storytelling, moral lessons, and societal reflections to engage readers on both emotional and intellectual levels. Despite extensive research on the benefits of reading and the emotional responses it evokes, a critical gap remains in understanding what drives readers to form deep emotional connections with specific works. This study seeks to identify the characteristics of a book that foster such connections. Using Bayesian Mindsponge Framework analytics, we analyzed a dataset of 129 Amazon reviews of Wild (...) Wise Weird, a collection of 42 fables that intertwine traditional storytelling with contemporary sensibilities, offering life lessons, humor, and social commentary. Of these reviews, approximately 66% expressed love for the book. The findings reveal that readers who describe the book as unique, whimsical, quirky, or innovative are more likely to express affection for it. Similarly, readers who are drawn to the book’s illustrations and characters tend to form stronger emotional connections. The cultural richness and representativeness of the book also emerged as significant factors in fostering readers’ love. The book successfully captures and conveys the depth, charm, and moral essence of Vietnamese culture to a global audience. Readers have expressed heartfelt gratitude after engaging with the book, underscoring its success in fostering meaningful emotional connections. Thus, insights from this analysis offer actionable recommendations for stakeholders in the literary ecosystem, from authors and publishers to marketers, to enhance readers’ emotional attachment and commitment to books.

Wildfires have become an increasing global threat to public health and quality of life. Many countries employ air quality monitoring and reporting systems to mitigate health risks associated with air pollution, including wildfire smoke. This study investigates the factors influencing individuals’ sensitivity to air quality information, specifically their likelihood of reducing or ceasing outdoor activities in response to air quality ratings, with a focus on wildfire smoke exposure in the western United States. Using the Bayesian Mindsponge Framework (BMF) analytics, the (...) study analyzed data from 2,237 participants in the Boise Metropolitan Area of Idaho and Boise State University. The findings reveal that women, older individuals, and those with higher educational levels are more likely to reduce outdoor activities at lower unhealthy AQI levels (the lowest being ‘good air quality,’ while the highest being ‘hazardous air quality’), while individuals with higher incomes are less responsive. Women and older adults, in particular, are even more likely to eliminate all outdoor activities. Additionally, individuals who perceive wildfire smoke as more severe than other natural disasters are more inclined to reduce or eliminate outdoor activities at lower unhealthy air quality levels. Experiences of wildfire smoke-related illness—either personally or within their households—further amplify this effect. These findings highlight the importance of localized, context-specific approaches to AQI dissemination and wildfire smoke risk communication to build resilience and safeguard public health in the face of escalating wildfire challenges driven by climate change.

Vietnam is a communist country. For a Marxist ideologue, “religion is the opium of the masses.” But many communist countries—over the years—have evolved from a strictly atheistic persuasion to a tolerance for religious practices. Except probably in North Korea, this transformation from an atheistic perspective to religious tolerance has become a phenomenon in communist countries like Russia and China.Vietnam did not have that experience. This paper will show that religious pluralism was tolerated, even accepted, in communist Vietnam. I will show (...) how vibrant this religious amalgamation is in Vietnam and demonstrate, as in the case of market economics thriving in communist countries, that Vietnamese communism and religious pluralism can robustly coexist with each other.

Background: If collectivistic-oriented family carers choose professional care for dependents with dementia, they risk being stigmatised as failing their obligation. This may influence dementia care choices. Research question: How may individualistic and collectivistic values influence choices in dementia care? Method: Qualitative design with in-depth interviews with a total of 29 nurses, 13 family members in Norway and the Balkans and 3 Norwegian dementia care coordinators. A hermeneutic content-focused analysis was used. Ethical considerations: Ethical approval was obtained from the Regional Ethics (...) Committee for Research, South-Eastern Norway, and the nursing homes’ leadership. Findings: Family domain reasons why institutionalisation of dependents with dementia was seen as a last resort: obligation towards family members, particularly parents; worry about other family members’ reactions and inability to cope with the care for the person with dementia. Social domain reasons: feelings of shame and stigma regarding dementia, particularly in connection with institutionalisation of family members. Discussion: Children’s obligation towards their parents is an important aspect of the morality of collectivistic societies. Institutionalising parents with dementia may cause feelings of guilt and shame and worry about being stigmatised and ostracised. To avoid blame and rejection, caregiver(s) try to keep the fact that family members have dementia ‘in the family’. The decision to accept professional healthcare for dependents with severe dementia or have them admitted to a geriatric institution was postponed as long as possible. Conclusion: Family care morality may constitute a significant barrier against seeking professional help for persons with dementia, a barrier based on the expectation that the family will care for their old, even when suffering from severe dementia. Hence, stigma and shame may significantly affect the provision of care. Culturally tailored information may encourage family carers to seek professional help before the disruptive influence of the disease makes institutionalisation the only feasible option. (shrink)

In the recruitment process, manually selecting suitable candidates from curriculum vitae (CVs) for a job description (JD) is both time-consuming and expensive. Traditional keyword-based methods struggle to capture skill semantics, prompting the development of more advanced JD-CV matching systems. This paper aims to investigate and construct an ontology-based skills recommendation system, with objectives including creating a skills ontology and developing skills matching methods for JD-CV pairs. The objective of our approach is to enhance the accuracy and contextual relevance of recommendations (...) by utilizing the proposed score. The proposed skills ontology and skills matching strategies are applied to a real dataset in Vietnam. The results of our study can automatically recommend a list of CVs for a given JD. Furthermore, the findings indicate that our proposed model surpasses comparative approaches by a margin of at least 1% to 5%. Overall, the study demonstrates the potential of utilizing ontology-based approaches to offer a practical solution for enhancing hiring practices. (shrink)

The phrase ‘chết phải toàn thây’, which has no direct English translation, can be roughly interpreted as ‘one must die with an intact body’. This belief, deeply rooted in Vietnamese culture, significantly influences how the body is treated after death. It is often linked to the idea that the body must remain whole for the soul to rest peacefully or transition smoothly into the afterlife. While many societies, particularly in the Western world, view the donation of organs after death as (...) a noble act, the belief in ‘chết phải toàn thây’ poses a significant barrier to promoting organ donation in Vietnam. This essay highlights the cultural origins of this belief and explores a broader interpretation of ‘toàn thây’ or ‘intact body’ in the modern era. The phrase ‘chết phải toàn thây’, firmly ingrained in Vietnamese culture for thousands of years, reflects the influence of religious and philosophical traditions, particularly Confucianism, Buddhism and Taoism.1 Confucianism emphasises filial piety (xiao), which includes preserving bodily integrity after death as a sign of respect for one’s parents and ancestors.2 Taoism, with its focus on the soul’s immortality and harmony with nature, regards the body as a sacred vessel crucial for maintaining a balance between the physical and spiritual realms.2 Together, these traditions form a cultural framework that assigns profound spiritual and emotional significance to the body, making its preservation a deeply held ….

The digital era brings various benefits to adolescents. However, operating on the digital environment without sufficient knowledge and skills will expose them to multiple types of risks, especially in the country with low digital safety education rate like Vietnam. The current study examines factors that can contribute to cultivating adolescents’ digital resilience using the information-processing reasoning of the Mindsponge Theory. A UNESCO dataset of 1061 Vietnamese high school students was analyzed using the Bayesian Mindsponge Framework analytics. It is found that (...) adolescents’ daily Internet usage frequency, parents’ Internet safety guidance, and teachers’ safety guidance are positively associated with digital resilience. However, the effects of parents’ and teachers’ Internet safety guidance on digital resilience are conditional on the daily Internet usage frequency. Parents’ guidance only enhances adolescents’ digital resilience if they use the Internet less than four hours per day. In contrast, the positive effect of teachers’ guidance on adolescents’ digital resilience becomes stronger when the students spend more time on the Internet (more than 1 hour). Based on these findings, we suggest that adolescents can learn to minimize risks and protect themselves by exposing more to the digital environment. Parents’ and teachers’ supports are important in enhancing adolescents’ capability to deal with digital threats, but types of supports need to be carefully considered to avoid reverse impacts on adolescents’ resilience.

This study investigates the dynamic relationship between knowledge management systems, particularly emphasizing knowledge acquisition and dissemination, and their impact on academic staff's teaching motivation. By employing the Bayesian Mindsponge Framework (BMF), data from 676 academic staff at higher education institutions in Vietnam was analyzed, revealing a complex interplay of factors. Notably, positive associations were found between knowledge acquisition, knowledge dissemination, and teaching motivation. However, the interaction effect of knowledge acquisition and knowledge dissemination appeared to be negatively associated with teaching motivation. (...) This suggests the possible existence of a resource curse of knowledge in improving staff’s teaching motivation. It is recommended that the knowledge systems are refined to reduce complexity and that staff are trained with better knowledge processing methods for reducing resource curse risks. (shrink)

Folklore has a critical role as a cultural transmitter, all the while being a socially accepted medium for the expressions of culturally contradicting wishes and conducts. In this study of Vietnamese folktales, through the use of Bayesian multilevel modeling and the Markov chain Monte Carlo technique, we offer empirical evidence for how the interplay between religious teachings (Confucianism, Buddhism, and Taoism) and deviant behaviors (lying and violence) could affect a folktale’s outcome. The findings indicate that characters who lie and/or commit (...) violent acts tend to have bad endings, as intuition would dictate, but when they are associated with any of the above Three Teachings, the final endings may vary. Positive outcomes are seen in cases where characters associated with Confucianism lie and characters associated with Buddhism act violently. The results supplement the worldwide literature on discrepancies between folklore and real-life conduct, as well as on the contradictory human behaviors vis-à-vis religious teachings. Overall, the study highlights the complexity of human decision-making, especially beyond the folklore realm. (shrink)

Purpose This paper aims to investigate the extent of personal privacy concerns expressed by university students in Vietnam while using TikTok, the influence of peer interactions and social norms on privacy attitudes and behaviors and the strategies used by university students in Vietnam to mitigate privacy risks on TikTok. Design/methodology/approach A qualitative approach using semi-structured interviews was used to gather data on the following: the degree to which Vietnamese university students express concerns about their personal privacy while using TikTok; how (...) peer interactions and social norms influence privacy attitudes and behaviors; and the strategies these students use to mitigate privacy risks on the platform. Findings Findings indicate that although university students exhibit a relatively low level of concern regarding their personal privacy on TikTok, peer influences and societal norms significantly shape their attitudes and behaviors on the platform. Moreover, students use several strategies to mitigate privacy risks, such as selective content sharing and refraining from engaging with unknown links. Practical implications These insights provide valuable implications for the development of targeted interventions and educational initiatives aimed at fostering a more privacy-conscious TikTok user community among university students in Vietnam. Originality/value This research fills a critical gap in the existing literature by focusing on the influence of social norms and peer influences on privacy attitudes and behaviors on social media platforms. While prior studies have explored various factors impacting privacy concerns on social media, the role of social dynamics has been understudied. Moreover, the research specifically addresses the lack of investigation into privacy concerns on TikTok, a platform rapidly gaining popularity among younger demographics. (shrink)

Case law retrieval is the task of locating truly relevant legal cases given an input query case. Unlike information retrieval for general texts, this task is more complex with two phases (legal case retrieval and legal case entailment) and much harder due to a number of reasons. First, both the query and candidate cases are long documents consisting of several paragraphs. This makes it difficult to model with representation learning that usually has restriction on input length. Second, the concept of (...) relevancy in this domain is defined based on the legal relation that goes beyond the lexical or topical relevance. This is a real challenge because normal text matching will not work. Third, building a large and accurate legal case dataset requires a lot of effort and expertise. This is obviously an obstacle to creating enough data for training deep retrieval models. In this paper, we propose a novel approach called supporting model that can deal with both phases. The underlying idea is the case–case supporting relation and the paragraph–paragraph as well as the decision-paragraph matching strategy. In addition, we propose a method to automatically create a large weak-labeling dataset to overcome the lack of data. The experiments showed that our solution has achieved the state-of-the-art results for both case retrieval and case entailment phases. (shrink)

Deformation of ground during tunnelling projects is one of the complex issues that is required to be monitored carefully to avoid the unexpected damages and human losses. Accurate prediction of ground settlement is a crucial concern for tunnelling problems, and the adequate predictive model can be a vital tool for tunnel designers to simulate the ground settlement accurately. This study proposes relatively new hybrid artificial intelligence models to predict the ground settlement of earth pressure balance shield tunnelling in the Bangkok (...) MRTA project. The predictive models were various nature-inspired frameworks, such as differential evolution, particle swarm optimization, genetic algorithm, and ant colony optimizer to tune the adaptive neuro-fuzzy inference system. To obtain the accurate and reliable results, the modeling procedure is established based on four different dataset scenarios including preprocessed and normalized, preprocessed and nonnormalized, non-preprocessed and normalized, and non-preprocessed and nonnormalized datasets. Results indicated that PPN dataset scenario significantly affected the prediction models in terms of their perdition accuracy. Among all the developed hybrid models, ANOFS-PSO model achieved the best predictability performance. In quantitative terms, PPN-ANFIS-PSO model attained the least root mean square error value of 7.98 and a correlation coefficient value of 0.83. Overall, the attained results confirmed the superiority of the explored hybrid AI models as robust predictive model for ground settlement of earth pressure balance shield tunnelling. (shrink)

This paper applies a proposed modified stochastic fractal search algorithm (MSFS) for dealing with all constraints of optimal reactive power dispatch (ORPD) and finding optimal solutions for three different cases including power loss optimization, voltage deviation optimization, and L-index optimization. The proposed MSFS method is newly constructed in the paper by modifying three new solution update mechanisms on standard stochastic fractal search algorithm (SSFS). The first modification is to keep only one formula and abandon one formula in the diffusion process (...) while the second modification and the third modification are used in the first update and the second update. In two updates of SSFS, solutions with low quality are updated with high probability while other solutions with high quality do not get chances to be updated. This manner results in the fact that some promising solutions around the high quality solutions can be missed. In order to tackle this restriction, the second modification of MSFS is to newly update the worst solutions in the first update and the best solutions in the second update. In the third modification, all existing formulas of SSFS in the two updates are abandoned and the same new proposed technique is used for updating such solutions in two updates. Compared to SSFS, the three modifications can bring advantages to MSFS such as using smaller number of produced solutions per iteration, spending shorter execution time, finding better optimal solutions, and owning more stable search ability. Furthermore, the proposed method also sees its effectiveness and robustness over SSFS by testing on IEEE 30-bus system and IEEE 118-bus system with three different single objectives for each system. The proposed method can find less minimum, average, and maximum for all the cases in addition to faster search speed. Besides, the proposed method is also compared to other methods such as PSO-based method group, GA-based method group, DE-based method group, and other recent methods. Result comparisons also indicate that the proposed method can be more efficient than almost all these methods with respect to less minimum and smaller values of control parameters. As a result, evaluation of the performance of the proposed method is that it should be used for seeking solutions of ORPD problem. (shrink)
