Combining Numerical Simulations, Artificial Intelligence and Intelligent Sampling Algorithms to Build Surrogate Models and Calculate the Probability of Failure of Urban Tunnels
Authors: Domingues Vinícius Resende , Ozelim Luan Carlos de Sena Monteiro , Assis André Pacheco de , Cavalcante André Luís Brasil
Published: May 2022

When it is necessary to evaluate, with a probabilistic approach, the interaction of urban tunnels with neighboring structures, computational power is an important challenge for numerical models. Thus, intelligent sampling algorithms can be allies in obtaining a better knowledge of the result’s domain, even if in possession of a smaller number of samples. In any case, when sampling is limited, the evaluation of the risks is also restricted. In this context, artificial intelligence (AI) can fill an important gap in risk analysis by interpolating results and generating larger samples quickly. The goal of the AI algorithm is to find an approximation function (also called a surrogate model) that reproduces the original numerical simulation behavior and can be evaluated much faster. This function is constructed by performing multiple simulations at special points obtained by intelligent sampling techniques. This paper used a hypothetical case to validate the methodological proposal. It concerns the sequential excavation of a tunnel, about three diameters deep, interacting with a seven-story building. First, the three-dimensional numerical model (FEM) was solved deterministically, and then its domain and mesh were refined. After that, another 170 solutions were numerically obtained from FEM software, strategically sampling the random variables involved. Sequentially, based on 31 artificial intelligence techniques, it was evaluated which variables were of greatest importance in predicting the magnitude of vertical displacement in the foundation elements of a surrounding building. Then, once the most important variables were selected, the 31 artificial intelligence techniques were again trained and tested to define the one with the least R-squared. Finally, using this best-fit algorithm, it was possible to calculate the probability of failure using massive samples, with sizes on the order of 107. These samples were used to illustrate the convergence of the Simple Monte Carlo Sampling (MC) and Latin Hypercube Sampling (LHS). The main contribution of this paper is methodological; therefore, this new procedure can be aggregated to state-of-the-art risk assessment methodologies in tunnel-related problems.
Neighboring Green Network and Landscape Metrics Explain Biodiversity within Small Urban Green Areas—A Case Study on Birds
Authors: Sultana Marufa , Müller Max , Meyer Magdalena , Storch Ilse
Published: May 2022

Cities’ green areas are fragmented patches and are often confined to smaller sizes than the higher built-up proportions. Such small-sized green areas can be essential components of green infrastructure to compensate for biodiversity loss. As a proxy to biodiversity, we studied birds in nine small green area locations of Freiburg and eight area locations in Regensburg in Germany. We investigated the neighboring green networks (distance to the nearest water body and another green area) and landscape metrics (patch abundance and habitat heterogeneity at a 1 km radius) that might benefit and explain bird richness and composition in small green areas. We found that the variations in the observed species richness and composition at the surveyed locations were better explained solely by green networks in Freiburg and by green networks and landscape metrics in Regensburg. In general, it indicates that a small green area could be biodiverse if its spatial distribution considers a nearby water body and other green areas, allowing a higher abundance of similar patches and habitat heterogeneity in the neighborhood.

Published: May 2022

Urban informalities have shown global unprecedented growth rates in the past 50 years, currently housing around two thirds of Cairenes. As outdoor activities are fundamental to urban life, improving environmental performance of this urban product is essential. This paper investigates microclimate in Cairo’s informal areas and how to improve it through low-tech interventions. It aims to identify relevant heat stress counterstrategies, and how they can be promoted among and accepted by residents. Building on previous work regarding an Outdoor Spaces Environmental Performance Assessment OSEPA tool, the researchers identified needed intervention areas within Imbaba informal district. Through an extensive participatory process, the team developed tailored solutions that help improve the urban microclimate using low tech and low-cost interventions. The field work identified vital prerequisites and revealed the necessity of engaging various stakeholders to ensure ownership and applicability. The analysis concludes with an Outdoor Spaces Environmental Performance Improvement OSEPI model for developing solutions to improve urban microclimate within spaces of informal areas and a toolbox for relevant interventions. This serves both as an input in informal areas upgrading projects and designing low to middle-income neighbourhoods. Thus, ensuring environmental justice and counteracting current practices that predominantly ignore environmental issues especially increased heat stress.
What Do We Know and What Do We Need to Know about COVID-19’s Implications on Business Economics? From Bibliometric Analysis to a Conceptual Framework
Authors: Zhu Zhuoyue , Xie Hongming
Published: May 2022

This paper presents a bibliometric analysis of COVID-19-related research in business economics. The current status of research on economic management in COVID-19 is shown through descriptive statistics. The corresponding knowledge maps are obtained based on keyword clustering analysis, and research topics of interest to Chinese and foreign readers are identified. This paper finds that the impact of COVID-19 on business economics is mainly manifested in six major themes, namely COVID-19 and crisis management, COVID-19 and supply chain, COVID-19 and digitalization, COVID-19 and economic development, COVID-19 and organizational management, and COVID-19 and sustainable development. Based on these research foundations, this paper proposes a research framework for economic management under the influence of COVID-19. It describes the current research status, research directions, and future topics of six key research themes from macro, meso, and micro perspectives, to provide a knowledge base for research and practice in the field of economic management in the post-pandemic era.
Sustainable and Responsible Design Education: Tensions in Transitions
Authors: Boehnert Joanna , Sinclair Matt , Dewberry Emma
Published: May 2022

Sustainable and Responsible Design (SRD) harnesses design’s potential to address eco-social problems and in doing so challenge the status quo of design education by reframing the social and ecological consequences, boundaries and agencies of design. This critical and transdisciplinary approach frays the edges of traditional design disciplines with embedded and reflexive modes of learning. We describe characteristics of SRD education and present theories of learning to empower students in this complex terrain. The learning associated with SRD education is ecologically engaged, participative, critical, expansive and designerly. We recount case studies of our own experiences advancing sustainable and responsible undergraduate design education in the UK. We identify path constraints such as disciplinary fragility, appropriation, and power dynamics in the design school. The push for a revision of priorities generates tensions where there is often greenwashing rhetoric of sustainability and inclusivity. We describe strategies and tactics to address these tensions. We highlight the agency we have as educators and designers and argue that design education can only meaningfully participate in response to the challenges presented by climate change, other types of ecocide, and social problems when educators make substantive commitments to supporting sustainability literacies and design approaches that serve the interests of diverse stakeholders.
Employment Training at the University: Employment Expectations in Times of Pandemic
Authors: Torres-Gordillo Juan-Jesús , García-Martínez Paloma Belinda
Published: May 2022

This study analyses the job expectations found in early childhood education students as well as the main personal and academic aspects that influence their training during the COVID-19 pandemic. A nonexperimental ex post facto study based on a descriptive, correlational and inferential approach is developed. A total of 168 students from the University of Seville (Spain) participated. The results show a moderate to high level of expected employability. However, salary expectations and how the university is perceived regarding employability reveal more negative data. Expectations are higher for men, first-year students and those from a high socioeconomic background. The results suggest the value of offering guidance to students according to their employment preferences, before and during their training, to avoid considering the university as the only educational institution available.
Sustainability and Influence of Machine Translation: Perceptions and Attitudes of Translation Instructors and Learners in Hong Kong
Authors: Liu Kanglong , Kwok Ho Ling , Liu Jianwen , Cheung Andrew K.F.
Published: May 2022

In this era of globalisation, translation technologies have become more popular in daily communication, the education sector, and the translation industry. It is observed that there is a prevalent use of machine translation (MT) among translation learners. The proper use versus abuse of MT can be a critical issue regarding its role in and impact on translation teaching. This exploratory study aims at investigating learners’ and instructors’ knowledge of MT, experience in MT use, perceived MT quality, ethics of MT use, and the perceived relationship between MT and translation training, in order to figure out the usefulness of MT in translation competence acquisition and the necessity of MT training. To this end, we conducted surveys and semi-structured interviews and found that the influence of MT in translation competence acquisition is determined by the properties of MT and learners’ quality. MT is particularly helpful in gaining lexical knowledge and knowledge to ensure translation efficiency, but not in bicultural knowledge. However, such usefulness builds on learners’ language proficiency, analytic ability, and learning motivation. In light of the findings, issues including the sustainability of MT from ethical and linguistic perspectives, and the potential and proper use of MT to inform translator training, are discussed.
Agricultural Heritage: Contrasting National and International Programs in Brazil and Italy
Authors: Ocelli Pinheiro Raphael , Paula Luiza F. A. de , Giardino Marco
Published: May 2022

Agricultural systems comprise an interdisciplinary field that studies the complex dimensions of agriculture. They should not be characterized only by their agricultural value, as they are part of several social, cultural, geological, and historical domains. We carried out quantitative and qualitative research to present and compare the current state of agricultural heritage programs and their development in Brazil and Italy, contrasting with the Globally Important Agricultural Heritage Systems (GIAHS) by the Food and Agriculture Organization (FAO). To this end, the history and the extension of these programs and sites were recovered. Moreover, the agricultural landscape diversity, the development of the regions, research and outreach, along with the communities, entities and government bodies involved were identified. Through a combination and quality of technical assessment and communities’ description, the analyzed agricultural heritage programs prove to be an endless source of useful information to the definition of policies aimed at rural areas, in addition to serving as a monitoring tool for many issues regarding biocultural diversity in landscape. Moreover, it shows where there is room for improvement while the countries are committed to engaging in national policies and entities on the promotion of agricultural heritage programs as major steps for investing in the “greening” of agricultural policies at different levels.

Authors: Kassem Hazem S. , Ismail Hamed , Ghoneim Yomna A.
Published: May 2022

Institutional linkages and information flow between agricultural organizations play a critical role in addressing sustainability issues and promoting agrarian innovation. The aim of this study was to evaluate institutional relations and information between the various actors within the agricultural knowledge and information system (AKIS). The study focused on eight actors within the AKIS in Dakahlia governorate of Egypt, namely policy, extension, research, agricultural cooperatives, higher education, secondary education, credit, and the private sector. Thus, the survey sample included 11 representatives of each actor with 88 respondents. Data were collected by a standardized questionnaire distributed online. The graph theoretical technique was used for the quantitative assessment of information flow and institutional linkages established among actors. The findings indicated that agricultural extension ranked first about their real cause and effect on the rest of the system, having a value of 7.95. Two critical information pathways within the AKIS sustained innovation outcomes: (1) higher education–extension–agricultural cooperatives, (2) research–extension–agricultural cooperatives. The results also revealed that agricultural cooperatives ranked second after the extension component on the extent of supplying information to other members in the AKIS, with a value of 4.8. In contrast, the highest component received information from other components (7.6). By analyzing institutional linkages and information flow, this article gives insights to policymakers on the mechanisms that still need to be strengthened and the information gaps between actors to address the challenges of sustainable rural development.
Sustainable Tourism, Social and Institutional Innovation—The Paradox of Dark Sky in Astrotourism
Authors: Escario-Sierra Francisco , Álvarez-Alonso César , Moseñe-Fierro J. Antonio , Sanagustín-Fons Victoria
Published: May 2022

Astrotourism is an emerging type of sustainable tourism based on the observation of the dark sky, free of light pollution, and of all the experiences that have developed around it. The views and perceptions of the main social actors and their constellations and interactions are considered. Both the public decision-makers concerning astrotourism and the civil society involved were analysed in this research through a case study in Aragon, an inland Spanish region. New institutionalism in sociology based on the actors provides a coherent structural framework and explanation of the most relevant aspects in astrotourism in Aragon as well as help to understand the social and institutional innovation, in the sense that civil society has organised itself for many years to show and bring astronomy closer to the social majority; in light of this social reality, institutions have had to respond appropriately, taking and allowing for the participation of astronomical associations, in order to develop tourist experiences in relation to the appropriate dissemination of this science. Even more so, we studied the socioeconomic dynamics and territorial impacts. Thanks to the application of a qualitative method, specifically, semi-structured interviews with relevant informants in the territory, we discovered a hidden relevant social situation around astrotourism. Is the so called “paradox of dark sky” that emerges in communities where social welfare gains such as widespread access to artificial light are jeopardised by a new collective approach to artificial light control and light pollution that prevents high-impact emotional experiences around the dark sky, but takes into account that astrotourism is an opportunity for the endogenous and sustainable socioeconomic development of these forgotten areas.
Optimal Design of Subway Train Cross-Line Operation Scheme Based on Passenger Smart Card Data
Authors: Li Maosheng , Li Hangcong
Published: May 2022

The network operation of the subway can reduce the number of passenger transfers and improve subway operation efficiency. Based on the subway smart card data, this paper proposes an optimal design method for the cross-line operation scheme of subway trains. The method firstly calculates the OD matrix between subway stations, the passenger section flow, and the transfer flow according to the passenger smart card data. It then optimizes the design of the subway train cross-line operation plan, including determining the routing type of cross-line operation and the number of trains running. Finally, for the lines with cross-line operation conditions in the urban subway system, we design the cross-line operation schemes under all possible combinations. According to the volume of the cross-line passenger flow that the cross-line trains can carry, the top-ranked operation plans are preferably recommended. Taking the Chengdu subway network as an example, the research results show that, in the Chengdu subway network, the North Railway Station, Xibo City Station, and South Railway Station bear the highest transfer demand. The transfer demands that can be undertaken by cross-line trains are 23,934, 16,710, and 13,024 trips per hour, respectively. This shows that the proposed design method can accurately and reasonably screen out the transfer stations and lines with an urgent need for cross-line trains.

Authors: Phuong Linh Nguyen , Tuan Khanh Cao , Duc Nhuan Nguyen , Thi Uyen Nguyen
Published: May 2022

This study aims to explore the impact of absorption capability, innovation capability, and branding capability on the performance of retailers. Using the resource-based view (RBV), this study proposes a research model on the direct impact of absorption capability, innovation capability, and branding capability on firm performance as well as the indirect impact of absorption capability on firm performance which is mediated by both innovation capability and branding capability. By surveying 201 middle and senior managers representing 201 Vietnamese retailers, PLS-SEM was used to test the hypotheses. The research results show the important role of developing innovation capability and branding capability in improving retailer performance. The findings also reveal the significant impact of absorption capability on retailers by an indirect mechanism through innovation capability and branding capability. Based on the findings, practical implications for Vietnamese retailer managers are suggested to improve their performance by strengthening and developing absorption capability, innovation capability, and branding capability.

Authors: Vătămănescu Elena-Mădălina , Dinu Elena , Stratone Mădălina-Elena , Stăneiu Roxana-Maria , Vintilă Florina
Published: May 2022

The present paper sets out to investigate the relationships among several key constructs that cover the work patterns and processes in the context of the COVID-19 pandemic. Emphasis is laid on the leader-team communication, the fostering of a strong team culture, team performance and satisfaction with teamwork in the case of virtual teams. The scrutiny is intended to complement recent developments in the field which compared traditional and virtual teams at different levels by adding knowledge to virtual teams’ communication and interaction patterns and processes. In this vein, an online survey was conducted with 175 members from different virtual teams. The findings showed the advancement of a pertinent conceptual model, mostly displaying significant relationships among constructs. Four out of the five formulated hypotheses were validated, the highest influences being reported between leader-team communication and team culture, respectively, and between team performance and satisfaction with teamwork. Furthermore, the structural model explained over 50% of the variance in the satisfaction with teamwork, thus supporting the relevance of the inferred relationships.
Organizational Well-Being of Italian Doctoral Students: Is Academia Sustainable When It Comes to Gender Equality?
Authors: Corvino Chiara , De Leo Amalia , Parise Miriam , Buscicchio Giulia
Published: May 2022

Despite the fact that there are several researchers reporting the risks of doctoral students in terms of mental health, there is still a lack of studies exploring their well-being at an organizational level, looking at the difference between male and female PhD students. This work aims at describing gender differences in the organizational well-being of doctoral students in an Italian context. A sample of 121 Italian PhD students filled an adaption of the ANAC questionnaire (National Authority for Anti-Corruption) for an organizational well-being assessment between June and July 2021. The results show that there are a number of well-being indicators for which female PhD students have statistically lower scores than men regarding: (1) the perception of health and safety at work; (2) career development; and (3) job autonomy. Practical suggestions to improve the academic system in terms of sustainability for preventing PhD students’ organizational malaise with a particular focus on gender equality are provided.

Authors: Azmi Naif Al , Sweis Ghaleb , Sweis Rateb , Sammour Farouq
Published: May 2022

The construction industry plays an essential role in economic development since it is one of the largest industries all over the world. Blockchain has the potential to reshape the structure of all accessible networks in the future. Construction businesses are increasingly interested in embracing blockchain technology to improve supply chain sustainability performance and supply chain resilience in times of globally increasing risks and volatility. This study evaluates the readiness of actors involved in the producing of concrete goods to emphasize the necessity to bring blockchain into the construction industry, as it may be a solution for supply chain resilience and long-term sustainable growth. Qualitative and quantitative research methods were used in collecting and analyzing the data and testing the hypotheses. Data were collected using an online questionnaire distributed to 300 employees who work within the biggest concrete producing companies in Saudi Arabia. 120 respondents completed the questionnaires. Additionally, confirmatory semi-structured interviews with experts in supply chain financing, IT departments, and procurement departments have been conducted; the study’s findings revealed a low level of blockchain knowledge within Saudi Arabia’s construction industry, since (90%) of respondents have not worked with Blockchain technology. Several technologists barely understand it, and the level of readiness is very low. However, there is a lot of potential, and it is worth investing in it combined with other technologies such as BIM technology. In this study, the authors have sought to provide a measure of Saudi professionals’ attitudes and understanding of blockchain technology solutions within the construction industry in Saudi Arabia. Furthermore, the study’s novelty aimed to provide a grasp of the conceptual, theoretical, and fundamental features of blockchain technology in the construction industry, as blockchain solutions could benefit the global economy by increasing levels of monitoring, tracing, and confidence in international supply chain resilience.
Digital Teaching Competence: A Systematic Review
Authors: Revuelta-Domínguez Francisco-Ignacio , Guerra-Antequera Jorge , González-Pérez Alicia , Pedrera-Rodríguez María-Inmaculada , González-Fernández Alberto
Published: May 2022

This systematic literature review aimed to discover how the concept of digital teaching competence (DTC) has been developed, how its dimensions have been defined, and how educational development models and models that evaluate teachers’ digital teaching competence have been constructed. Concurrently, this review aimed to draw conclusions on the implementation processes of digital teaching competence in order to uncover its strengths and limitations, and to propose future lines of research to develop it further in initial teacher training programmes. A systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology was proposed in order to achieve these aims. We chose the time frame of 2015 to the end of 2021 in an attempt to cover the appearance of the first scientific articles dealing with the subject, up until the present day. Thus, the inclusion criteria covered scientific research articles from the Web of Science (WoS) and Scopus databases, in English or Spanish, that focused on samples of teachers in primary education, secondary education, baccalaureates, and initial teacher training. The database searches, which will be detailed in depth later, initially provided a corpus of 127 articles, which was reduced to 26 articles after screening for duplicity and applying the inclusion criteria.
Social Progress beyond GDP: A Principal Component Analysis (PCA) of GDP and Twelve Alternative Indicators
Authors: Wang Bing , Chen Tianchi
Published: May 2022

What social progress is and how to measure it are seemingly plain but essentially intri-cate questions that have not been clarified to date, which has led to various social problems and development failures. Designed after the Great Depression in the 1930s, Gross Domestic Product (GDP) has been, on the one hand, regarded as the greatest invention of the 20th century and is widely accepted as the primary indicator for social progress, but on the other hand, it has been criticized as knowing the price of everything but the value of nothing. The Beyond GDP Movement that has been active since the 2010s has inspired global interest in designing indicators to replace or supplement GDP, but none of them stands out as GDP’s successor. We take 12 influential indicators that consider beyond GDP and carry out a Principal Component Analysis (PCA) to investigate their correlations. The results indicate that GDP per capita (GDPP) can explain 65.61% of the information in the first principal component (PC) and account for 51.10% of the information related to the total 13 indicators, indicating its major role in social progress. Most indicators have strong correlations with GDPP, not beyond, and only the Ecological Footprint per capita (EFP) and Happy Planet Index (HPI) that have negative and weak correlations with GDPP, respectively, can provide new perspectives and values beyond GDP. Social progress is based upon various public values, and the indicators are the measurements of these values. Although GDP and economic values play major roles during social development, other indicators and their potential public values cannot be ignored. Prioritizing these public values and monitoring their indicators are essential to achieving sustainable and comprehensive social progress.
The Environmental Patents, Changing Investment, Trade Landscape, and Factors Contributing to Sustainable GVCs Participation: Evidence from Emerging Market Countries
Authors: Xu Liuyang , Nadeem Muhammad , Wang Zilong
Published: May 2022

Over the last two decades, the global investment and trade landscape has been transformed to include emerging economies. Theoretical studies have shown that countries can benefit from various channels to participate/integrate into global value chains. However, little is known empirically about the factors that determine the country-level and bilateral participation of emerging market countries in global value chains. We apply the generalized method of moments and fixed-effects approaches to the Eora-MRIO global value chains database to fill this research gap for twenty-three emerging market countries from 1995 to 2018. Key findings indicate that the most important determinants of country-level participation in global value chains are the country’s environmental patents and its level of economic development. Other indicators are positively associated with global value chain participation, if not determinative. The results of a gravity model for bilateral global value chains participation show that geographic proximity and policy and environmental measures are positively associated with value-added trade. These results provide insights and lessons for investors and emerging economies in creating or joining sustainable value chain activities.
Attribution of Changes in Vietnam’s Labor Productivity
Authors: Oh Wankeun , Kang Seung Won
Published: May 2022

This study examines the change in labor productivity in Vietnam by means of a Fisher index decomposition and attribution analysis. The results can be summarized as follows. First, the aggregate labor productivity is decomposed into pure labor productivity and structural change from 2007 to 2019. All of the aggregate labor productivity, pure labor productivity, structural change, and interaction terms have increased by 69.83%, 36.74%, 24.20%, and 8.89%, respectively. Second, the percentage change in labor productivity is attributed to 20 sub-industries by pure labor productivity and structural change. The sum of the multi-period attribution of pure labor productivity and structural change shows that the manufacturing industry positively dominates (15.84%) and plays a key role in economic development. The positive pure labor productivity and structural change in the manufacturing industry imply that the structural bonus hypothesis does hold in the industry. The findings also indicate that pure labor productivity, especially in the service industry, should be improved to sustain economic growth.

Published: May 2022

Within the framework of the LEADER approach to rural development applied in rural areas of the European Union, a high degree of social innovation (SI) has been achieved with the support of public–private partnerships. This research analyzes the different forms of SI achieved in specific projects in marginal rural areas facing depopulation. These initiatives make important, sometimes intangible, contributions to rural society, which are not sufficiently valued in rural development practice. Using an exploratory qualitative methodology, we made a selection of projects carried out in rural areas of Spain and Italy by searching for specific keywords (“innovation”, “entrepreneurship”, and “LEADER”) in the European Network of Rural Development database. According to the typology of promoters, we considered Transnational Cooperation Projects promoted by various Local Action Groups (LAGs), by public sector initiative and by private promoters. In-depth interviews were also conducted. The main findings include: the crucial role played by local leaders, social enterprises and LAGs in overcoming resistance and reluctance amongst the local community to participate in and support rural development projects; the importance of creating collective learning processes; the complexity of the network affects the number of contributions; the need for long-term continuity of processes and projects, and the importance of combining exogenous and endogenous development and knowledge.
Freshwater Aquaculture Development in EU and Latin-America: Insight on Production Trends and Resource Endowments
Authors: Gyalog Gergő , Cubillos Tovar Julieth Paola , Békefi Emese
Published: May 2022

This paper provides a comparative overview of decadal changes in aquaculture production in the European Union (EU-27) and Latin America and the Caribbean (LAC). Contrary to other regions of the world, freshwater fish farming in these two territories is a marginal sub-segment of the aquaculture sector. Using an indicator-based approach, we track development tendencies in freshwater aquaculture, focusing on the main established and emerging species, diversification, and shifts in the mean trophic level of farmed animals. Geographical patterns in production trends are revealed in both regions. The study attempts to explain between-region and between-country differences in aquaculture growth by analyzing freshwater resource endowments at region-level and country-level, using total renewable water resources (TRWR) as an indicator of water-abundancy. Thermal optimum of main produced species is matched against climate conditions prevailing in main producer countries to provide further understanding of spatial heterogeneity in growth rates of aquaculture sector.
Using Plastic Sand as a Construction Material toward a Circular Economy: A Review
Authors: Al-Sinan Mazen A. , Bubshait Abdulaziz A.
Published: May 2022

Recently, research on innovative approaches to and practices for plastic waste management in a circular economy has gained momentum. Plastic waste pollution poses a serious environmental concern. At the same time, the cement industry is among the biggest sources of CO2 emissions, which poses another environmental challenge. This makes plastic sand bricks an attractive alternative to concrete blocks and bricks. This paper looks at the recent studies regarding the development of plastic sand bricks and the different percentages of plastic and sand used in the bricks. The literature review reveals that there is a lack of studies that evaluate plastic sand construction materials from an economic perspective. Such studies are essential if the industry is to invest in and adopt this alternative construction material. Plastic sand bricks could be a workable solution for combating issues related to solid waste. The compressive strength decreased with increasing ratios of plastic to sand. Plastic sand bricks weighed less than the conventional bricks. Issues requiring further investigation include: dealing with varying proportions and types of plastic, the lack of understanding of the long-term performance of plastic sand bricks, the flammability and fire resistance of plastic sand bricks, and the absence of appropriate standards and regulations for recycling plastic into plastic sand bricks. This paper allows us to look ahead in terms of some specific technical needs, the translation of the emerging technology into practice, and new ideas to decrease plastic pollution.
A Symbiotic System of Irrigated Rice–Earthworm Improves Soil Properties and Rice Growth in Southern China
Authors: Zhang Yin , Guan Mei , Chen Can , Wang Ren , Lv Guangdong , Huang Huang , Guan Chunyun
Published: May 2022

Earthworms have been studied in many ecosystems, demonstrating their high ecological value. However, there are few studies on the coupling of earthworms to irrigated paddy fields. On this basis, a symbiotic system of irrigated rice and earthworms was established with a wide-ridge cultivation model, and a combination of field experiments and pot experiments was carried out in Southern China. The results showed that the symbiosis of irrigated rice and earthworms in the pot experiment significantly loosened the soil by 5–10 cm, compacted the soil by 10–20 cm, increased the soil pH value by 0–10 cm, and increased the content of soil organic matter by 5–20 cm compared with rice monoculture. Due to the significant increase in leaf area index and grain weight at the mature stage, the white root at the heading and grain filling stages improved significantly, and the yield of irrigated rice also increased significantly by 15.39%. However, in the field experiment, due to the low survival rate of earthworms, the effect of inoculating earthworms was not significant. This study confirmed the beneficial effect of earthworm inoculation on the paddy field ecosystem, and provided a research basis for introducing earthworms into the paddy field ecosystem, realizing the sustainable development of rice cultivation, and ensuring world food security.
Identification of Farmers’ Barriers to Implement Sustainable Management Practices in Olive Groves
Authors: Parra Gema , Garcia-Lopez Luis Joaquin , Piqueras José A. , García Roberto
Published: May 2022

Current European agriculture policies and strategies are aimed to boost the transition from the predominant conventional to a more environmentally friendly agriculture model. As part of this, it is crucial to identify the barriers that exist to implementing crop-specific management practices so that appropriate mitigating steps to overcome these can be executed. Participatory action research, where farmers are research actors rather than objects, is essential to identify the main barriers farmers have to face. The objective of this study was to identify the main barriers to the adoption of a combination of sustainable management practices in olive cropping in Southern Spain. A 20-item questionnaire was designed and responded to by 200 Spanish olive farmers. Exploratory and confirmatory factor analyses were used to assess the factor structure. The final best fit model included 14 items that were grouped in the following four barriers or facilitators: “lack of training/formation”, and “lack of economic/policy support” as barriers; “wellbeing–nature connection” and “environmental impact awareness” as facilitators. The mean scores on the different factors were higher than the theoretical mean, so the identification of the two barriers and the two facilitators for implementing sustainable practices was robust. Farmers, especially women, are concerned about their knowledge limitation in implementing sustainable management practices, which opens a window of opportunity for specific actions (i.e., training and demonstrative events) to be taken for accomplishing the agriculture sector transformation.
National Investment Framework for Revitalizing the R&D Collaborative Ecosystem of Sustainable Smart Agriculture
Authors: Lee Doyeon , Kim Keunhwan
Published: May 2022

Demographic, economic, and environmental issues, including climate change events, aging population, growing urban-rural disparity, and the COVID-19 pandemic, contribute to vulnerabilities in agricultural production and food systems. South Korea has designated smart agriculture as a national strategic investment, expanding investment in research and development (R&D) to develop and commercialize convergence technologies, thus extending sustainable smart agriculture and strengthening global competitiveness. Hence, this study probes the status of smart agricultural R&D investment from the perspectives of public funds, research areas, technologies, regions, organizations, and stakeholders. It examines 5646 public R&D projects worth USD 1408.5 million on smart agriculture in 17 regions and eight technology clusters from 2015 to 2021. Further, it proposes a pool of potential collaborative networks via a case study of strawberry, a representative veritable crop inspiring smart agriculture, to demonstrate the study framework’s usefulness in promoting smart agriculture and establishing a sustainable R&D collaboration ecosystem. The proposed framework, accordingly, allows stakeholders to understand and monitor the status of R&D investment from various perspectives. Moreover, given the insight into the tasks belonging to technical areas and regions that require sustainable cooperation in smart agriculture, central and local governments develop policies to reinforce sustainable smart-farming models.
The Economic Recovery from Traffic Restriction Policies during the COVID-19 through the Perspective of Regional Differences and Sustainable Development: Based on Human Mobility Data in China
Authors: Li Yawen , Yang Yushan , Luo Guorong , Huang Jizhou , Wu Tian
Published: May 2022

In the post-epidemic era, balancing epidemic prevention and control with sustainable economic development has become a serious challenge for all countries around the world. In China, a range of interventions include detection policies, clinical treatment policies, and most notably, traffic policies have been carried out for epidemic prevention and control. It has been widely confirmed that massive traffic restriction policies effectively brought the spread of the pandemic under control. However, restrictions on the use of transportation infrastructure undermine the smooth functioning of the economy. Particularly, China has a vast territory, with provinces differing in economic development, leading industries and transportation infrastructure; economic shock varies from region to region. In this case, targeted policies are the key to sustainable development. This paper sets forth advice for the Chinese government on its measures to boost the economy by analyzing regional differences in the impact of massive traffic restriction policies, based on large-scale human mobility data. After applying the Data Envelopment Analysis model, we classify Chinese provinces into different regions from the perspective of economic gradient, degree of internationalization and level of traffic convenience, respectively. Classification results are matched with the indicators of New Venues Created and the weekly Volumes of Visits to Venues from Baidu Maps. We find that the regional differences in the recovery of investment and consumption levels are striking. Based on the findings, we suggest that the government should adjust the intensity of traffic restrictions and economic stimulus policies dynamically according to regional differences to achieve sustainable economic development.
Encouraging Reuse in the Corrugated Packaging Industry Using Persuasion and Operant Conditioning

Greenhouse gas emission is a major contributor to climate change and global warming. Many sustainability efforts are aimed at reducing greenhouse gas emissions. These include recycling and the use of renewable energy. In the case of recycling, the general population is typically required to at least temporarily store, and possibly haul, the materials rather than simply throwing them away. This effort from the general population is a key aspect of recycling, and in order for it to work, some investment of time and effort is required by the public. In the case of corrugated cardboard boxes, it has been observed that there is less motivation for the general population to recycle them. This paper explores different means of motivating people to reuse, and not just recycle, with different types of incentives. The paper addresses the use of persuasion techniques and operant conditioning techniques together to incent the general population to adopt sustainable efforts. The paper makes an attempt to segment the general population based on persuasion preference, operant condition preference, and personality type to use different forms of incentives and motivational work unlike any approaches found in the literature review. Four types of persuasion techniques and four types of operant conditioning are combined to give 16 different types of incentives. Two online surveys are conducted, and their data are analyzed (using entropy, Hamming distance, chi-square, and ANOVA). The results indicate that “positive reinforcement ethos” is a cost-effective way to incent the general population. The results of this study can be applied to a wide range of applications such as incentives for solar panels, incentives for vaccination, and other areas wherein sustainability-centric behavior is encouraged.

This study aimed to investigate the effects of nonlinear and linear varied practice compared to a constant linear practice on inhibitory control and reaction time, which are capacities that involve cognition in preadolescents. Eighty-three participants in the 8th grade participated in the study. They were assigned to two experimental groups (varied practice), taught using nonlinear pedagogy (NLP) and linear pedagogy (VLP), respectively, or one control group (constant practice), taught using linear pedagogy (CLP). All participants were tested for inhibitory control (congruent and incongruent conditions) and simple reaction time. Overall, varied practice (both linear and nonlinear) induced larger improvements than constant practice under both congruent (p = 0.026) and incongruent (p = 0.013) conditions of inhibitory control. Additionally, VLP provided greater improvements in inhibitory control (for the incongruent condition) than NLP and CLP. Although NLP and VLP may be preferable to CLP approaches for enhancing executive functions in preadolescents, VLP seems to be the most effective approach aimed to improve cognition within PE classes.

Indigenous perspectives on the effects of climate change are frequently elicited through surveys and interviews, and the responses are compared to meteorological data. However, there remains a limited approach to examining the underlying predictors that best determine Indigenous support for adaptation strategies. This study utilizes partial least squares-structural equation modeling (PLS-SEM) to identify the main indicators of Indigenous support for coping with unfavorable climate impacts. Using a case study and a purposive sampling approach, a survey of 328 Indigenous peoples was conducted in rural Kinabatangan, Sabah, Malaysia. Results showed that communities’ attitudes had a large effect on the Indigenous support for adaptation (f2 = 0.380), followed by the communities’ awarenesses (f2 = 0.063), rapid onset events (f2 = 0.051), and climate impacts on tourism (f2 = 0.016). Communities prioritize the impacts of climate change on their health, livelihoods, and environmental resources. Nevertheless, they do not draw a causal link between the effects and responses to climate hazards. Coping strategies such as the inclusion of Indigenous livelihoods, a bottom-up approach, and transparent communication are suggested to cultivate Indigenous support for climate change adaptation. Decision-makers can apply these findings to prepare climate change policies and enhance the adaptation strategies of Indigenous communities.
