Purpose: This chapter aims to examine machine learning (ML) models for predicting credit card fraud (CCF).

Need for the study: With the advance of technology, the world is increasingly relying on credit cards rather than cash in daily life. This creates a slew of new opportunities for fraudulent individuals to abuse these cards. As of December 2020, global card losses reached $28.65billion, up 2.9% from $27.85 billion in 2018, according to the Nilson 2019 research. To safeguard the safety of credit card users, the credit card issuer should include a service that protects customers from potential risks. CCF has become a severe threat as internet buying has grown. To this goal, various studies in the field of automatic and real-time fraud detection are required. Due to their advantageous properties, the most recent ones employ a variety of ML algorithms and techniques to construct a well-fitting model to detect fraudulent transactions. When it comes to recognising credit card risk is huge and high-dimensional data, feature selection (FS) is critical for improving classification accuracy and fraud detection.

Methodology/design/approach: The objectives of this chapter are to construct a new model for credit card fraud detection (CCFD) based on principal component analysis (PCA) for FS and using supervised ML techniques such as K-nearest neighbour (KNN), ridge classifier, gradient boosting, quadratic discriminant analysis, AdaBoost, and random forest for classification of fraudulent and legitimate transactions. When compared to earlier experiments, the suggested approach demonstrates a high capacity for detecting fraudulent transactions. To be more precise, our model’s resilience is constructed by integrating the power of PCA for determining the most useful predictive features. The experimental analysis was performed on German credit card and Taiwan credit card data sets.

Findings: The experimental findings revealed that the KNN achieved an accuracy of 96.29%, recall of 100%, and precision of 96.29%, which is the best performing model on the German data set. While the ridge classifier was the best performing model on Taiwan Credit data with an accuracy of 81.75%, recall of 34.89, and precision of 66.61%.

Practical implications: The poor performance of the models on the Taiwan data revealed that it is an imbalanced credit card data set. The comparison of our proposed models with state-of-the-art credit card ML models showed that our results were competitive.

This chapter provides information on the development of Vietnamese education under the influence of global forces based on the analysis of relevant education research and policies using Wolhuter’s frameworks. In the process of coming up with ways to develop education in the face of different influences of globalization, besides having reactions with patterns commonly found in countries around the world, Vietnam also has responses that reflect its own political, sociocultural and economic characteristics. The state still plays a controlling role in education at all levels and many culture-related features that have existed throughout the country’s history have hardly changed, namely aspects related to teachers, learners and teaching and learning methods. To sustain its education in the globalized era, Vietnam must make more efforts in various aspects such as the link between education and employment, the logic of education objectives, the feasibility and appropriateness of curricula, quality of education, especially of higher education and equality in education for underprivileged groups.

Purpose: To explore emotional support, daily housework assistance, and economic support for older adults provided by the Vietnamese family within the context of the impacts of socio-economic, demographic, and other factors.

Methodology: (1) The researchers used data from censuses taken from 1989 to 2019; national surveys of Internal Migration, Labor and Employment and other topics; and recent large sample sociological surveys (2) adapted a modified Diamond Care Model (Ochiai, 2009) to analyze effects of the characteristics of older adults; and of the country’s laws, policies, and socio-economic changes, on the families’ caregiving activities supporting the older adults.

Findings: The family is still the most important institution providing care for older adults in Viet Nam. Most older people live with their children and see this as an age-old security solution despite differences related to lifestyles and interests. However, when the average number of working-age people per older person decreases, as older adults live longer, household sizes are smaller, and there is increased large migration, the demand for non-family caregiving for older adults will increase. Since social services to help meet this demand are limited, the traditional family support system for the elderly in Viet Nam will face many challenges as families try to assure the quality of care needed in the very near future.

Value: This chapter shows systematically a relationship between elderly care in the Vietnamese family and socio-economic, demographic, and associated factors based on comprehensive data sources. The results can help us think about how to create an appropriate future model for taking care of older adults in Viet Nam that combines the efforts of families and the support of comprehensive social policies by the community.

As a consequence of the huge loss and damage caused by natural disasters all over the world, an impressive amount of attention is currently being given to a holistic approach in disaster risk management (McEntire, Fuller, Johnston, & Weber, 2002). The world experiences more and more natural disaster impacts in spite of numerous efforts, advancing sciences, and more powerful technologies. Indeed, current disasters are more complex, and climate change poses a greater potential for adverse impacts (Aalst & Burton 2002). Hence, there is a need to reassess the existing disaster risk reduction approaches due to problems in the existing risk management approaches, and new risks brought by climate change and by environment degradation.

Vietnam is an emerging economy in the South East Asia region. Its Generation Z is gradually taking the lead in the country. But rather than breaking away from the previous generations, this generation also shows a strong preference towards local values and solid commitment to social issues. Thus, traditional culture elements are increasingly integrated in every aspect of Generation Z’s life, such as advertising and fashion. Instead of hanging out at coffee places, they go for bubble tea. They still appreciate the traditional values but integrate them within a modern context. Brands chase after these young people by adapting their values into their products and services. In the work place, the Vietnamese Generation Z is less confident. They are partially lost in career development with poor career counselling in the education system. They desire new experience and new learning opportunities. Generation Z, who were born beginning in 1995, emerges in Vietnam as a fresh and promising force.

The chapter reflects on the coopetition concept and its role in combining cooperation and competition with a paradoxical situation between them. Likewise, it illustrates how coopetition gains a mutual advantage for the collaborative relationship of value creation, new product development (NPD), knowledge acquisition, and organizational performance in inter-organizations. However, it is necessary to build a friendly approach and proper management to ensure effective coopetition. The rationale, though, is the following: coopetition defines innovation performance; coopetition represents knowledge recombination in both inter-organizational and intra-organizational conditions; the coopetition outcomes state knowledge creation and firm’s innovation that lead to new ideas and new variations improving organizational relationships. At the same time, it is highlighted how the customer relationships are aligned in the enterprises and how knowledge transfer in different alliances influence dynamic and complex character exploring tacit and explicit knowledge. As far as knowledge is concerned in an organization, it illustrates the contribution of two essential elements in coopetition value creation, i.e., knowledge management and intellectual capital. By critically evaluating the following, we encourage coopetition and innovation to recognize knowledge and increase the performance of inter-organizational units. Moreover, the primary way for knowledge assessment in organizations is by collaboration with the competitors. Concluding, our theoretical approach acknowledges that knowledge sharing enables more efficient innovation by linking R&D efforts.

This chapter analyzes characteristics and changing patterns of marriage formation in Vietnam over the past 50 years, from various aspects including the motives underpinning marriage decision-making, the process of mate acquaintance, the criteria for mate selection, and marriage decision-making rights. The chapter is based on a review of data derived from the Vietnam Family Survey 2006 (MOCST et al., 2008) and the Vietnam Marriage Survey 2017 (Minh, 2021). It shows that the pattern of marriage formation in Vietnam has changed significantly in the past decades under the influence of various socio-economic and legal factors. Marriage is increasingly associated with the value of personal happiness. People today have many more opportunities to meet and get to know each other before marriage than older generations in the past. Adolescents spend more time getting to know their future spouse and have more options when choosing future partners before marriage. Marriage based on a partner’s individual qualities is preferred, gradually replacing mate selection based on family background. Parents’ power over their children’s marriage has decreased, while young people are becoming more and more independent in making decisions about their lives. In other words, today, it is the interests of the people involved in the marriage that matters, not only the interests of the family and kinship that determines marriages. However, despite these new marriage formation patterns, the belief that children’s marriage is an important affair for the whole family is still maintained. The general pattern is that there is a mix of personal factors and family circumstances regarding the marriage choices.

Unsustainable logging and illegal logging for domestic and international trade and trafficking continue to lead to deforestation. It is crucial that Sustainable Development Goal 15 ‘Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss’ is achieved to maintain the livelihoods of people and protect the planet. This is the case in Vietnam as well, where many people, including indigenous groups, rely on the forest for their survival. Drawing on semistructured interviews in Vietnam and a literature review, we investigate how the abuse of forest policies leads to human insecurity. From this, we propose solutions to (1) end unsustainable harvesting and illegal logging (SDG 15.7), (2) integrate the value of forests (culturally and economically) into national and local planning, the development process and poverty elimination strategies (SDG 15.9) and (3) improve the use of forest protection funding provided by international donors.

Digital marketing is becoming the dominant marketing communication method for companies and consumers around the world. The reason for this is due to the real time communication advantages that make it an effective marketing method. The aim of this chapter is to focus on how digital marketing relates to social entrepreneurship in Vietnam, thereby offering a new perspective on the role of social entrepreneurship in developing digital marketing techniques. This will contribute to the existing literature on digital marketing and social entrepreneurship by extending it to an emerging economy setting. Implications for practitioners and policymakers are given that highlight the need for more social enterprises to incorporate digital marketing techniques.

“The world needs science, science needs women” is the message given by UNESCO in the program for the development of women in science” (UNESCO, 2017). In Vietnam, women’s participation and achievements in scientific research is considered a great and important resource for industrialization and modernization. Even so, are there gender differences in scientific achievement in the social science research institutes in Vietnam? What factors influence the scientific achievement of female social researchers? The answers will be based on data from a 2017 survey with a sample of 756 researchers, of which 77.6% were female. The survey was conducted by the Vietnam Academy of Social Sciences, a leading, ministry-level national center for the social sciences in Vietnam. This chapter analyzed the scientific achievements of researchers through their position as principal investigators of research projects and their publications, and factors that may impact this. Bivariate and multivariate analyses of factors that may affect the scientific achievement of researchers found that gender differences in academic achievement in the social sciences in Vietnam was still prevalent. Female researchers’ scientific achievements were lower than those of their male counterparts. The contribution to science of Vietnamese female researchers was limited by many different factors; the most important were the academic rank of the researchers and gender stereotype that considered housework the responsibility of women.
