This study deals with three major topics: (1) the developed generations of 3D concrete printers, (2) the mix design approach for cement-based materials and (3) laboratory testing.

The big question is how to approach and follow the trend of 3D concrete printing technology with limited conditions such as printers, technology issues and budget. Therefore, this research focused on dealing with prominent issues, including printing equipment, mixed proportion design approaches and laboratory testing methods will be presented and analyzed.

The details of three printing equipment, including a printhead, a small-scale 3D printer, a 3D concrete printer and the printing process related to Simplify and Mach3 software, will be revealed. Secondly, the classification and efficient process will be given according to the mixture proportion design method proposed. Thirdly, laboratory testing will be conducted, including extrudability, buildability and printability. Finally, some highlight conclusions are given based on the appearance and quality of the samples printed.

Research has been carried out with cement-based materials and 3D concrete printer which adopted the screw extruders.

Mix design proportion method via coefficient and slump value proposed by the authors is a relatively effective and convenient method; the rheological properties, printing process and geometry of a sample are the most significant factors that decide the success of the printing work.

Additive manufacturing, widely known as 3D printing, has recently drawn the attention of researchers worldwide for a few decades. Thanks to its capability to transform a drawing into an object, the idea of 3D printing has also attracted the attention of engineers, architects and investors.

(1) Mix design proportion via coefficient and slump value proposed by the authors is a relatively effective and convenient method that can be implemented simply at the laboratory or the site. (2) The ranges of coefficients by weight of the water, sand and PP fibers to binder are (0.27–0.3), (0.6–1.0) and around 0.3, respectively. The maximum sand size was smaller than 2.5 mm, and the small amount of PP fibers enhanced the quality and significantly reduced the printed samples' shrinkage. (3) The printability is affected by mix proportion and the relationship between nozzle printing speed parameter and extrusion speed of motor turning. (4) The chosen layer height recommended smaller than 0.83 times nozzle diameter is reasonable and improves adhesions and buildability. (5) The printing open time of the concrete mixture of (12–15) minutes is a barrel to promote 3D concrete printing technology and needs improvement.

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.

Vietnam has repositioned itself from a war-torn country to a popular tourist destination. Although research on Vietnam tourism has grown in number, a macro analysis of national tourism governance and policies has largely been missing.

This synthesis paper offers a systemic analysis of Vietnam’s tourism accommodating intensified government intervention and dramatic market changes in recent decades. The authors offer a chronological analysis of tourism development along with the major political and economic turns of the country.

The patterns of tourism development reflect a compromise between centralization and decentralization of the governance system and a trade-off between economic and social objectives of development. Balancing these opposites, the internal strength of the domestic market and the resilience of communities and businesses become key assets for growth in circumstances where the socialist market economy continues to inform the current and future development of the industry.

Although the case of Vietnam is unique, the adaptive mechanism of the tourism industry highlighted in this paper offers a useful lesson for other developing countries. The research addresses tourism in the political economy in developing countries, which is valuable for researchers, policy analysts as well as practitioners in tourism.

The practical contribution of the study is derived from authors’ academic and industrial backgrounds. Findings from the study serve as a useful reference for those who embark on the study of tourism governance and policy-making in developing countries and problems associated with the economic transitional process. Those problems of the disparity between centralization and decentralization of the political system might not be only significant in Vietnam, but also prevail in developing countries. Thus, this study offers a point of departure for future empirical and comparative research on the kindship of tourism and political economy in a full scale.

The transitional economy as viewed through the tourism industry is prominently presented in the “evolutionary” approach to the transitional economy, which exhibits several unique features: the transition from a centrally planned (command) economy to a market economy and the manifestations of a socialist orientation in the modern economic management system (Vuong et al., 2019). While data from this study is mainly illustrative of the first point, the transition from a planned economy to a market economy, the second characteristic, the manifestation of a social orientation has only slightly been addressed and will need further elaboration in a future study. While Vietnam’s tourism positions itself in a socialist market-oriented economy might set a unique case, the study highlights the politics of tourism is shaped by the politico-economic system. The authors conclude that the adaptation of Vietnam tourism to a socialist market-orientated economy is better perceived as a social evolution achievement rather than a feature of capitalism.

The latest study on tourism governance (Bui et al., 2022) has outlined the evolution of the tourism administrative system and markets in the country; however, linkages of tourism to the broader political economic system have yet to be addressed. Addressing this gap, the authors carry out analysis of policies and governance from the insider’s viewpoint, when team members have been involved in numerous tourism planning and development projects, both on international and national scales. The practical experience along with thorough review of literature and statistical data contributes to shaping a fresh understanding of tourism in a transitional economy.

这篇综述对越南旅游业进行了系统分析, 包括近几十年来不断增强的政府干预以及巨大的市场变化。作者根据时间顺序分析了旅游业的发展以及该国的主要政治及经济的转变。此外, 政策文件的内容分析及旅游市场分析进一步说明了政治经济体系对旅游治理及政策的影响。

越南已将自己从一个饱受战争的国家重新定位成备受欢迎的旅游目的地。尽管对越南旅游业的研究不断增多, 但对国家旅游治理和政策的宏观分析却被之前的探究所忽略。此研究通过展示越南转型经济中的旅游治理模式连接了两个学科, 并且丰富了政治经济学和旅游学的文献。

旅游政策和市场分析反应了治理体系集权与分权之间的折中以及经济和社会发展目标之间的权衡。国内市场的内在优势以及社区及企业的韧性可以成为成长的关键资产来平衡这些对立面, 同时社会主义市场经济将继续影响产业的当前及未来的发展。因此我们的结论是, 越南旅游业适应社会主义市场经济应该被视为社会进化的成就, 而不是资本主义的特征。

考虑到一篇文章所能解决的问题有限, 作者无法就转型经济与中国进行比较研究。我们的研究为未来亚洲旅游与政治经济之间联系的实证和比较研究提供了一个出发点。

研究结果为发展中国家旅游治理和政策制定研究提供了有益的参考。

研究结果对于发展中国家旅游治理及政策制定研究具有重要参考意义。这项研究的成果对于发展中国家的旅游政策分析师, 特别是亚洲的研究人员来说很有价值。

当前的研究弥补了政治经济学中的一个研究不足, 即马克思主义学说及其与旅游业的对话。知识转移是本研究的一个亮点, 它源自对国家政治经济议程中的旅游治理的批判性分析。

Vietnam ha pasado de ser un país devastado por la guerra a convertirse en un popular destino turístico. Aunque la investigación sobre el turismo en Vietnam ha crecido en número, ha faltado en gran medida un macroanálisis de la gobernanza y las políticas turísticas nacionales. Nuestra investigación ha enriquecido la literatura tanto de la economía política como del turismo tendiendo un puente entre ambas disciplinas al presentar las pautas de la gobernanza del turismo en la economía de transición de Vietnam.

Este documento de síntesis ofrece un análisis sistemático del turismo de Vietnam que abarca la intensificación de la intervención gubernamental y los drásticos cambios del mercado en las últimas décadas. Los autores ofrecen un análisis cronológico del desarrollo del turismo junto con los principales giros políticos y económicos del país. Además, el análisis del contenido de los documentos políticos y el análisis del mercado turístico ilustran mejor las repercusiones de los sistemas político-económicos en la gobernanza y las políticas turísticas.

Las políticas turísticas y el análisis del mercado revelan un compromiso entre la centralización y la descentralización del sistema de gobernanza y un compromiso entre los objetivos económicos y sociales del desarrollo. Al equilibrar estos opuestos, la fuerza interna del mercado nacional y la resistencia de las comunidades y las empresas se convierten en activos clave para el crecimiento en unas circunstancias en las que la economía de mercado socialista sigue informando el desarrollo actual y futuro de la industria. Concluimos que la adaptación del turismo vietnamita a una economía socialista orientada al mercado se percibe mejor como un logro de la evolución social que como una característica del capitalismo.

Dentro del limitado abanico de cuestiones que podrían abordarse en un solo artículo, los autores no pueden establecer un estudio comparativo con China, en lo que respecta a la economía de transición. Nuestro estudio ofrece un punto de partida para futuras investigaciones empíricas y comparativas sobre la conexión entre turismo y economía política en Asia.

Las conclusiones del estudio sirven de referencia útil para quienes se embarcan en el estudio de la gobernanza y la formulación de políticas turísticas en los países en desarrollo.

Los resultados de la investigación son valiosos para los investigadores del sudeste asiático en particular y para los analistas de la política turística del mundo en desarrollo en general.

La presente investigación contribuye a un área poco investigada de la economía política, a saber, la doctrina marxista y su diálogo con el turismo. La transferencia de conocimientos es un aspecto destacado de esta investigación, que se ha derivado de un análisis crítico de la gobernanza del turismo en la agenda económica política nacional.

To review and synthesize findings from peer-reviewed research related to students’ sources of ideas for writing, and instructional dimensions that affect students’ development of ideas for composition in grades K-8.

The ideas or content expressed in written composition are considered critical to ratings of writing quality. We utilized a Systematic Mixed Studies Review (SMSR) methodological framework (Heyvaert, Maes, & Onghena, 2011) to explore K-8 students’ ideas and writing from a range of theoretical and methodological perspectives.

Students’ ideas for writing originate from a range of sources, including teachers, peers, literature, content area curriculum, autobiographical/life experiences, popular culture/media, drawing, and play. Intertextuality, copying, social dialogue, and playful peer interactions are productive strategies K-8 writers use to generate ideas for composing, in addition to strategies introduced through planned instruction. Relevant dimensions of instruction include motivation to write, idea planning and organization, as well as specific instructional strategies, techniques, and tools to facilitate idea generation and selection within the composition process.

A permeable curriculum and effective instructional practices are crucial to support students’ access to a full range of ideas and knowledge-based resources, and help them translate these into written composition. Instructional practices for idea development and writing: (a) connect reading and writing for authentic purposes; (b) include explicit modeling of strategies for planning and “online” generation of ideas throughout the writing process across genre; (c) align instructional focus across reading, writing, and other curricular activities; (d) allow for extended time to write; and (e) incorporate varied, flexible participation structures through which students can share ideas and receive teacher/peer feedback on writing.

Mwangale, Minister for Tourism and Wildlife, the Organizing Committee, presided by Mr. Maliti as well as to Universal Safary Tours as executing agency for having done everything to make our stay in Kenya pleasant and attractive.

The purpose of this paper is to investigate the determinants of the gender gap in the gross value of rice yield in Vietnam.

A panel data set of 12 provinces of Vietnam from 2010 to 2014 was used, collected from the Vietnam access to resources household survey. To measure the gender gap in the gross value of rice yield, two-stage least squares and Blinder – Oaxaca decomposition methods were used.

The gross value of rice productivity of male-headed households was 10.3 percent higher than that of female-headed households. The gender gap in rice productivity is caused by the endowment and structural effects; the endowment effect explained 53 percent of the gender gap in rice productivity and the structural effect 42 percent.

In order to reduce the gender gap and improve the gross value of rice yield, the following policies are suggested: female education and access to institutional services (extension and credit) should be improved and future research is needed to determine the reasons for gender discrimination in the agricultural production system.

The findings suggest that the difference in the gross value of rice yield between male- and female-headed households were mainly caused by endowments and returns from those endowments.

The purpose of this study is to investigate the resistance in management accounting practices (MAPs) in a developing economy in the manufacturing and service sectors in Vietnam.

Data collection was carried out using survey questionnaires in Vietnamese language. The questionnaires were distributed to selected respondents from the manufacturing and service organisations in Vietnam. Textual structuralism was used to analyse different categories of data, i.e. survey questionnaires, photos and qualitative texts obtained from the literature.

The findings indicate that the usage of MAPs is more prevalent in the manufacturing sector than in the service sector. In addition, various traditional and contemporary MAPs are being used concurrently in Vietnam, which challenges the classical twofold dichotomy between mere socialism and mere neoliberalism.

The textual and photographic structuralism is used in this study to analyse primary data (geography and society and time) in a static setting. Hence, it does not analyse the research phenomena in a dynamic equilibrium setting to view the development of the research phenomena over time. Further research could expand data collection to include longitudinal and dynamic settings.

MAPs can be implemented in economic systems ranging from command to capitalist systems. Although most countries in the world follow a mixed economic system, specific MAPs could be designed for a transitional economic system such as that of Vietnam. This affects both theorists and practitioners in Vietnam applying sustainable MAPs to boost a country's competitiveness during transition.

This study expands understanding of the conformity of MAPs in relation to economic systems under the Communist Party of Vietnam (CPV) – the ruling party of the Socialist Republic of Vietnam. Understanding the differences in the way these MAPs are utilised constitutes an essential area of the accounting discipline to advance MAPs in Vietnamese enterprises and progress theoretical development of sustainable MAPs.

On parle peu de la rénovation du patrimoine bâti en vue d'une utilisation pour le tourisme social. Pourtant après la dernière guerre, dans les démocraties populaires, nombre de propriétés ont été reconverties en sanatoriums ou en maisons de repos pour travailleurs.

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.

Prior studies have found a mixed result on the relationship between environmental commitment and firm performance. To shed a new light on this relationship, this study aims to draw on stakeholder theory, upper echelon theory and gender socialization theory to determine the mediating role of environmental collaboration with suppliers and the moderating role of chief executive officers (CEOs) gender into this relationship.

This study conducts a questionnaire survey to collect sample data of 177 CEOs in manufacturing firms in China. Structural equation modeling is used to analyze data and test hypotheses.

Empirical results show that environmental commitment has a positive influence on firm financial performance. Furthermore, the results show that environmental collaboration with suppliers mediates the link between environmental commitment and financial performance. In addition, CEO gender has a moderating effect on the relationship between environmental commitment and environmental collaboration with suppliers. Finally, CEO gender also moderates the indirect effect of environmental commitment on financial performance through environmental collaboration with suppliers.

Findings of this study helps to clarify the mediating and moderating mechanism in the relationship between environmental commitment and firm performance. That is this study helps to clarify the mixed relationship between environmental commitment and firm performance in prior literature. This study also provides new insight and knowledge for business managers to make better decision in dealing with the environmental issue to enhance firm performance.
