This essay aims to rectify a failure on the part of Western philosophers of technology to attend to the creative philosophical work of Li Bocong at the University of Chinese Academy of Sciences in Beijing. After a brief account of Li Bocong's personal contacts with the West and some remarks on his relationship to Marxism, we take up three aspects of his philosophy that can contribute to enlarging Western philosophical thinking about engineering and technology: (1) Li's analysis of engineering as more than design, (2) his argument for the relevance of the sociology of engineering, and (3) his conceptualization of engineering ethics as more than professional ethics., (© 2024.

Research papers published by Chinese and Indian researchers during 1998-2007 and cited at least 100 times by end of 2009 are analysed. There were 776 papers with at least one author from India (amounting to 0.32% of all papers from India) and 2260 papers with at least one author from China (0.4% of all papers from China) that have gone on to be cited at least 100 times. We have identified prominent authors and institutions, journals used and fields of research. Although highly cited Chinese papers were cited on average less often than the highly cited papers from India, Chinese authors have been able to place their papers in high impact journals such as Nature and Science far more often than Indian authors. The Indian Institute of Science, Bangalore, Tata Institute of Fundamental Research, Mumbai and Jawaharlal Nehru Centre for Advanced Scientific Research, Bangalore are the prominent Indian institutions, whereas universities in Hong Kong, Peking University, Tshing Hua University and several institutions under the Chinese Academy of Science dominate in China. In terms of citations, Chinese National Human Genome Centre Shanghai, Shanghai, tops the list. [ABSTRACT FROM AUTHOR]

Responding to globalization trends, many engineering schools are internationalizing their courses and curricula to prepare graduates for careers that involve working across countries and cultures. As a result, both students and staff are looking beyond study abroad to international work, research, and service learning opportunities as alternate pathways for high-impact experiential learning in global context. However, such programs can also pose unique challenges related to preparing students for professional practice abroad and systematically evaluating program outcomes and impacts among students and other stakeholders. This paper responds to these challenges by reporting on International Research and Education in Engineering (IREE) 2010 China, a summer engineering research abroad program. It describes orientation strategies designed to improve student readiness for global practice, and presents mixed-method assessment methods and results for global engineering competency and other key learning outcomes. The main audience for this paper includes faculty and staff who develop and support global learning experiences in engineering and other professional degree programs.

Contribution: This paper qualitative research delineates the thinking and behavioral patterns that reflect students' advanced level of epistemological thinking in project-based learning (PBL) activities and the associated impact factors. Background: PBL has been widely adopted in engineering education for its effectiveness in improving students' problem-solving abilities, collaboration skills, and academic achievement. The four stages of Perry's theory--Dualism, Multiplicity, Relativism, and Commitment (within Relativism)--depict students' epistemological development from dualistic to contextual relativistic thinking. Prior research suggested that participation in PBL could benefit students' development to relativistic thinking--the most revolutionary change in Perry's model. Nevertheless, how epistemological thinking was exhibited in the context of PBL, and the relationship between students' epistemological thinking and PBL learning activities both remain unclear. Research Questions: 1) What are demonstrations of students' relativistic thinking in PBL activities? and 2) What are the factors in regard to students' relativistic thinking in PBL activities? Methodology: Built upon quantitative results obtained using a modified Zhang's cognitive development inventory (ZCDI) developed in the context of Perry's theory, this paper explored demonstrations of students' relativistic thinking in PBL in a qualitative manner, and analyzed the associated factors based upon one-on-one interviews with 17 engineering students. Findings: In PBL activities, students' epistemological thinking is reflected in their solving problems within constraints, conducting feasibility analyses, exhibiting commercial awareness, having their thinking broadened, and more. Their epistemological thinking can be impacted by factors, such as guidance from professors, collaborations with peers, communications with other stakeholders, and complexity level of projects.

Universities contribute to economic growth and national competitiveness by equipping students with higher-order thinking and academic skills. Despite large investments in university science, technology, engineering and mathematics (STEM) education, little is known about how the skills of STEM undergraduates compare across countries and by institutional selectivity. Here, we provide direct evidence on these issues by collecting and analysing longitudinal data on tens of thousands of computer science and electrical engineering students in China, India, Russia and the United States. We find stark differences in skill levels and gains among countries and by institutional selectivity. Compared with the United States, students in China, India and Russia do not gain critical thinking skills over four years. Furthermore, while students in India and Russia gain academic skills during the first two years, students in China do not. These gaps in skill levels and gains provide insights into the global competitiveness of STEM university students across nations and institutional types., (© 2021.

This paper gives a brief analysis on the educational advantages and objects of NCWU. It believes that the educational philosophy and development direction of foreign school in engineering colleges must be set up on the basis of need of China and talents need, moreover, the development of the School of Foreign Studies must be analyzed by integrating into the whole development of NCWU. This paper put forwards the educational philosophy of "Drawing on Advantages, Avoiding Disadvantages, and Gearing Education to Society" and the Development Direction of "Rooted in Foreign Language and Characterised by Engineering and Business". It analyzes the problem of school of foreign studies in NCWU in Specialty Construction, teaching team and Construction of Discipline and puts forwards some solutions.

This paper regards the mechanical curriculum teaching as a design problem and uses environment-based design (EBD) method to solve it. First, environment components and their relations of the mechanical curriculum are found out by recursive object model (ROM). Then, conflicts in the teaching process are identified by analysing the above relations. Finally, solutions for solving these conflicts are generated. The proposed method is applied to mechanical manufacturing technology foundation (MMTF) curriculum with 217 students in grade 2016 in China. The solutions used in MMTF include decreasing the mental stress of students, developing more experimental projects, applying real cases and projects, adopting variety of assessments and so on. Compared with the performance of students in grade 2015, the average attendance rate and final scores are both increased, and three of the four achievement values of graduation attributes are risen. The practical example illustrates the EBD method is effective in improving curriculum teaching.

It is well-known that engineering is a key profession for both economic and social development. This is as true for China as it is for other countries which are in the process of development. However, what are the economic incentives for young people to enter the profession today? Currently, there are many studies of the rate of return to educational investment, but recent empirical studies of the rate of return to educational investment for engineers are uncommon. This is true generally, but especially for contemporary China. This is because it is difficult to obtain high-quality and representative sample data about engineers. This paper uses the data of the Chinese Family Panel Studies, 2010, and applies a Mincerian income function to estimate the rate of return to education for engineers who work in the private sector in urban China. The empirical results show that the rate of return for engineers is 12.3%, which is an impressive figure. It is in accordance with the current supply and demand of the Chinese labour market which requires many engineers to carry out construction and maintenance projects given China's continuing industrialisation, modernisation and urbanisation. However, the empirical results also show that compared with the rate of return to education for professional and technical personnel who are employed in business economics and finance, the rate of return for engineers is significantly lower. This may explain why in China today the attraction of engineering education for talented young people is declining, with more and more students choosing business economics and finance as their first choices of major and career, rather than engineering as in the past.

Research on engineering practice is scarce and sharing of qualitative research data can reduce the effort required for an aspiring researcher to obtain enough data from engineering workplaces to draw generalizable conclusions, both qualitative and quantitative. This paper describes how a large shareable qualitative data set on engineering practices was accumulated from 350 interviews and 12 field studies performed by the principal investigator and by students conducting PhD and capstone research projects. Ethical research practice required that sharing and reuse of qualitative data be considered from the start. The researchers' interests and methods were aligned to maintain sufficient consistency to support subsequent analysis and re-analysis of data. Analysis helped to answer questions of fundamental significance for engineering educators: what do engineers do, and why are the performances of engineering enterprises so different in South Asia compared with similar enterprises in Australia? Analysis also demonstrated the overwhelming significance of technical collaboration in engineering practice. Conceiving engineering practice as a series of technical collaboration performances requires a more elaborate understanding of social interactions than is currently the case in engineering schools. Another finding is that global engineering competency could be better described in terms of "working with people who collaborate differently". Research helped to demonstrate that formal treatment of technical collaboration in an engineering curriculum could help avoid student misconceptions about engineering practice that hinder their subsequent engineering performances.

As a very important skill both in English teaching and learning, reading strategy has been emphasized at home and abroad for a long time. Many scholars and teachers make research on undergraduates of English major or non-English major. However, the postgraduates are often neglected. Actually, it is also imperative to make a study among postgraduates of non-English majors, getting the information of their use of reading strategies and giving some useful suggestions to them. Therefore, this paper makes a quantitative study among 40 postgraduates from College of Mechanical Engineering in Chang'an University. This study shows that postgraduates of non-English major in Chang'an university do not frequently use reading strategies to improve their reading speed and proficiency. And there is a big difference between the successful learners and unsuccessful learners in terms of the use of reading strategies.

Purpose: This paper aims to discuss the challenge for the classical idea of professionalism in understanding the Chinese software engineering industry after giving a close insight into the development of this industry as well as individual engineers with a psycho-societal perspective. Design/methodology/approach: The study starts with the general review of the sociological concept of profession, professional and specialization of knowledge. Together with revealing the critical challenge from the empirical field of software engineering industry regarding its professionalization, a critique of the neglect of subjective agency in classical conception of professionalism in sociology theory and methodology is set out. Findings: A case study with interpretation of the subject's continuously developing identification with their specialization in knowledge and occupation from their narration of career experience reveals the dynamics in this development process relating to individual, social practice and societal factors. Originality/value: This paper contributes to empirical research of analyzing the professionalization process of software engineering and software engineers in relation to the concept of professionalism, and it contributes theoretically by discussing the challenge of this process to the development of professionalism within this highly knowledge-based industry in a Chinese societal context.

Purpose: The paper aims to explore the emotion learning experiences of some Chinese immigrants in Canadian engineering workplaces. Design/methodology/approach: The paper is based on life history style interviews with 14 Chinese immigrant engineers and 14 key informant interviews. Findings: Research respondents constructed a competitive, masculine, and individualistic engineering "culture" in Canada, where the emotional and the relational, supposedly central to the Asian and Chinese culture, are largely devalued. To fit into the individualistic culture, some Chinese immigrants learned to change their patterns of socialization and some became hard-nosed competitors. To ameliorate the deleterious effects of the alienating workplace environments, some resorted to their cultural teaching to maintain emotional health; some also tried to build collegiality and collectivity to humanize their work settings. Research limitations/implications: The study was not a comprehensive study of the emotion work in engineering workplaces. It does not capture the emotional order that may as well exist to afford different people differential negotiation power in the engineering culture. Social implications: The study suggests that while emotional connection and personalized relationship are "culturally" discouraged in engineering workplaces, they are of significant use value for immigrant workers and should be addressed to create humanized work environments. Originality/value: This is one of the few articles that examine emotion learning at the intersection of gender, race and class relations. (Contains 1 note.)

In May 2008, the worst earthquake in more than three decades struck southwest China, killing more than 80,000 people. The complexity of this earthquake makes it an ideal case study to clarify the intertwined issues of ethics in engineering and to help cultivate critical thinking skills. This paper first explores the need to encourage engineering ethics within a cross-cultural context. Next, it presents a systematic model for designing an engineering ethics curriculum based on moral development theory and ethic dilemma analysis. Quantitative and qualitative data from students' oral and written work were collected and analysed to determine directions for improvement. The paper also presents results of an assessment of this interdisciplinary engineering ethics course. This investigation of a disaster is limited strictly to engineering ethics education; it is not intended to assign blame, but rather to spark debate about ethical issues.

Considering that the course group regarding theory and design of mechanisms is characterized by strong engineering application background and the students generally feel very boring and tedious during the learning process, some teaching reforms for the theory and design of mechanisms are carried out to improve the teaching effectiveness in this paper. Taking the engineering cases as the teaching objectives, we combine the course contents with the engineering background. Moreover, in order to help the students understand the knowledge difficulty and improve the design capacity of the mechanisms and machines, the MATLAB technology is introduced into the theoretical teaching to provide assisted analysis. At the same time, the MATLAB is also introduced into the practical teaching to provide theoretical guidance. The teaching effect shows that MATLAB-based teaching reform under the engineering application can deepen the understandings of course contents for students, improve the interest in learning, strengthen the design capacity and develop the innovation ability.

This paper describes the research and practice on the reforming of the examination method of engineering graphics at Zhejiang University. Based on the theory of standardizing general examinations and emphasizing key examinations, a new combined examination method of multiple modes has been explored and practised. The examination modes include unified large-scale examination mode, interviewing mode, additional score mode by designing an object or writing a paper, and do-it-yourself mode, i.e. self-questioning, self-answering and self-evaluating. The method forms a good synergy between unified large-scale examination and free exertion. The final percentage score is given on the basis of the assessment mode reform. (Contains 3 tables.)

This paper summarizes the phenomenon of offshore outsourcing and relates it to the history and current state of engineering education and the engineering profession in Europe and the USA. In order to assess the climate affecting employment decisions by and about engineers we have used as sources mostly the serious press, with an emphasis on material dating from 2004 forward. The authors conclude that despite anxiety about the out-migration of engineering and technical jobs to places such as India and China, there is reason to see offshoring as the result of Western investment in capacity building in developing countries and to believe that the creation of new jobs will outpace the rate of job loss in Europe and the USA. The paper should serve as a prod to policy-makers and educators to set about creating an environment in which highly educated engineers and technical employees can continue a pattern of economic revitalization.

Gender differences in science and engineering (S&E) have been studied in various countries. Most of these studies find that women are underrepresented in the S&E workforce and publish less than their male peers. The factors that contribute to gender differences in experience and performance in S&E careers can vary from one country to another, yet they remain underexplored. This paper is among the first to systematically compare gender differences in the publication productivity of academic scientists and engineers with doctoral degrees in the U.S. and China. Findings from negative binomial regressions show that women publish less than their male counterparts in science but not in engineering in the U.S. In China, women do not differ from men in publication productivity in science but publish more than their male counterparts in engineering. In addition, we find that some background variables affect men's and women's publication productivity differently. The findings are analyzed in the context of the different cultures of the two fields (science vs. engineering) and of the two countries (the U.S. and China). Limitations and policy implications are also discussed.

With the advent of the era of big data and information technology, deep learning (DL) has become a hot trend in the research field of artificial intelligence (AI). The use of deep learning methods for parameter inversion, disease identification, detection, surrounding rock classification, disaster prediction, and other tunnel engineering problems has also become a new trend in recent years, both domestically and internationally. This paper briefly introduces the development process of deep learning. By reviewing a number of published papers on the application of deep learning in tunnel engineering over the past 20 years, this paper discusses the intelligent application of deep learning algorithms in tunnel engineering, including collapse risk assessment, water inrush prediction, crack identification, structural stability evaluation, and seepage erosion in mountain tunnels, urban subway tunnels, and subsea tunnels. Finally, it explores the future challenges and development prospects of deep learning in tunnel engineering. [ABSTRACT FROM AUTHOR]

This paper describes the development of an aero control experiment apparatus (ACEA) for use in aerospace control practical courses. The ACEA incorporates a systematic multihierarchy learning and teaching method, and was designed to improve aerospace engineering students' understanding of unmanned aerial vehicle (UAV) control systems. It offers a number of standard experimental modules at three levels: component, system, and simulation and evaluation. The software and hardware design methods used in the modules were chosen to allow students to conduct experiments in a simple, more hands-on manner. As a result, they were able to select or reconfigure their experiments and so continuously improve their skills and extend the ACEA itself. The practical curriculum module-s-grouped in three skill levels of basic experiments, case study, and independent design--were applied in a 3-year M.Sc. course, UAV Control Systems. The marking criteria created to evaluate students' achievements are presented, along with some results of this evaluation.

The Tibetan Plateau stands as one of China's largest middle and low latitude permafrost regions. However, the effects of global warming and human activities have led to permafrost thawing, inducing surface instability and posing significant threats to infrastructure and indigenous communities. The deployment of Lu Tan-1 (LT-1), China's premier L-band synthetic aperture radar (SAR) satellite constellation, offers a novel opportunity to assess these changes. This paper evaluates the deformation of critical engineering corridors, such as the Qinghai-Tibet Railway (QTR) and the Qinghai-Tibet Highway (QTH), utilizing time-series InSAR techniques with LT-1 SAR constellation data. We introduce both Stacking InSAR and a multi-baseline persistent scatterer multitemporal (MT-InSAR) method to enhance permafrost and engineering corridor deformation detection capabilities. Results obtained through the MT-InSAR approach reveal line-of-sight (LOS) deformation velocities of permafrost in the Beiluhe region ranging from -90 mm/y to approximately 70 mm/y, with an average velocity amplitude of 0.06 m/y. Differential displacement between alpine meadows and alpine deserts across the Beiluhe region is successfully discerned using LT-1 SAR data. Deformation velocities of QTR, QTH were found to be lower than that of permafrost, with average velocities of 0.027 m/y. These findings underscore the LT-1 SAR constellation's potential to serve as a valuable SAR data source for monitoring engineering corridor deformation within the Tibetan Plateau permafrost region.

Finally, some prospects for space grid structures are discussed. [ABSTRACT FROM AUTHOR]

Purpose: This article aims to analyze emergent learning practices for globalizing work through two research questions: "What are the conceptualizations of work represented by the Virtual Factory and how do they mediate globalizing work?" and "What is the potential of expansive learning efforts to expand conceptualizations towards the emergent learning practices of globalizing work?". Design/methodology/approach: Cultural-historical activity theory is applied, specifically the historical tool-mediated activity, concept formation and the zone of proximal development. A dynamic hierarchy of conceptualizations forms the framework for expansive learning efforts. Data were gathered by ethnographic and development interventionist methods from a distributed engineering design project. Findings: The paper finds that, historically, multi-layered conceptualizations of work face developmental challenges in globalizing work. Expansive learning efforts enhance the emergent learning practices when orienting global participants to motivating "why" and "where-to" conceptualizations. In order to turn emergent practices into sustainable learning practices, material representations need to be created to mediate the bottom-up and top-down conceptualizations at the interfaces of distributed work. Research limitations/implications: Emergent learning practices are studied longitudinally through concrete work in transformation. The learning approach emphasizes developmental interventions at global workplaces. Practical implications: Expansive learning efforts at different levels of conceptualization, may be supported by tools that mediate and sustain emergent learning practices. Social implications: Global workplace learning should be a concern of those involved with corporate social responsibility. Originality/value: Emergent learning practices offers a new approach for studies of globalizing work through its multi-layered conceptualizations of work. (Contains 3 figures and 4 tables.)

Developing nations including Bangladesh are significantly lagging behind the millennium development target due to the lack of science, technology and engineering education. Bangladesh as a least developing country has only 44 engineers per million people. Its technological education and gross domestic product growth are not collinear. Although limited progress was made in humanities, basic sciences, agriculture and medical sciences, a vast gap is left in technical and engineering education. This paper describes the present condition of engineering education in the country and explores ways to improve engineering education in order to meet the national as well as global skills demand. (Contains 3 tables and 7 figures.)

To effectively identify the key material parameters of different zones of concrete face rockfill dams and improve the efficiency of parameter optimization, a global sensitivity analysis method of parameters based on sparse polynomial chaotic expansion (sPCE) is proposed in this paper. The latin hypercube sampling method is used to select multiple groups of material parameters, and then finite element method is used to calculate the displacement of dam characteristic nodes in dam body. On this basis, the displacement is expanded by sPCE, and the polynomial basis function is reconstructed by orthogonal matching pursuit to improve the construction and analysis efficiency of the proxy model. According to the chaos coefficients, Sobol' indices are calculated to evaluate the influence of the material parameters and their interaction on different displacements of the dam. The results show that the sPCE model can accurately simulate dam displacement and its statistical characteristics with a relatively small sample size. The sensitivity of the same parameter has spatial variability, and under the influence of parameter levels and spatial distribution of different materials, the parameter sensitivity ranking of different zones has certain differences. The proposed method provides a new reference to sensitivity analysis and uncertainty analysis for practical engineering., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Ran et al.

Oil and gas reservoirs in volcanic rocks are a particular type of unconventional reservoir and present unique challenges for exploration and production engineers. To help the oil industry understand volcanic reservoirs and solutions to complex development problems, we reviewed their key engineering technologies as well as their geological characteristics. The distinctive geological characteristics of volcanic hydrocarbon reservoirs are strong heterogeneity, low porosity and permeability, complex fracture systems, etc. The volcanic reservoir rock types in order of hydrocarbon abundance are basalt (38.5%), andesite (15.9%), volcaniclastic (12.1%), and rhyolite (11.5%). The porosity ranges from 0.1 to 70%, and permeability ranges from 0.0007 to 762 md. In some commercially developed volcanic reservoirs of China, the average porosity is 7.7–13%; the average permeability is 0.41–3.4 md. Engineers have applied a variety of adapted technologies to produce volcanic reservoir economically. Horizontal wells can increase production and reserves by 4–6 times those of vertical wells, and longer wells are preferred. Specialized hydraulic fracturing techniques are suggested, including small or mixed proppant size, second HF treatment after proppant slugging, high-viscosity frac fluid with high-temperature resistance, special fluid loss reducer, high pump pressure, Extreme Overbalance Perforating, limited-entry fracturing, matrix acidizing, etc. Water control measures include producing below critical rates, partial perforation or penetration, controlling hydraulic fracture height, using horizontal wells, implementing complete cementing job, etc. Well productivity evaluation should be conducted to understand well performance and appropriately allocate production rates among wells, using the modified AOF method and other productivity prediction models considering breakdown fracture gradient, gas slippage effect, non-Darcy effect, etc. Well sites need to be selected based on recognizing profitable lithologies, lithofacies, high porosity and permeability, relatively developed fracture systems, thick net pay zones, etc. The critical questions for the industry are how to enhance volcanic reservoir recovery with more efficient and economic hydraulic fracturing and water control techniques. This is one of the first papers systematically summarizing the engineering technologies and unique solutions to develop volcanic reservoirs. Further and more complete reviews can be carried out in the future, and more novel and effective techniques can be explored and tested in the field. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to establish a model to evaluate the benefits of building information modeling (BIM) from the owners' perspective. The model analyzes the correlation between five secondary benefit indicators and their subsystems: product, financial, organizational, management and strategic. The final key factors of BIM benefits provide a decision-making basis for owners to raise the efficiency of BIM application. Design/methodology/approach: Firstly, the authors combed 31 BIM-related literature and interviewed experts to identify 15 preliminary benefit indicators. The authors established a BIM benefit evaluation system based on relevant concepts, including two primary indicators, five secondary indicators and 15 tertiary indicators. Secondly, the authors analyzed the indicators by the extension theory of matter element analysis and a questionnaire survey of expert opinion. Finally, the new method was applied to a case study of a large shopping center in east China for empirical verification. Findings: A BIM benefit evaluation model, including a three-tiered hierarchy of primary, secondary and tertiary indicators, was constructed through literature review and expert opinions. The model determined the critical factors of BIM benefits, enhanced understanding of owner benefits and improved BIM application under the owners' leadership. Originality/value: At present, most studies focus on specific project stages or benefit indicators. This study developed an integrated BIM benefit evaluation system that targets owners. The findings could foster the development of China's construction industry, promote owner-led BIM application and advocate adopting the benefit evaluation method. [ABSTRACT FROM AUTHOR]

Nowadays, with the leap-forward development of computer technology and the transformation of information technology management concepts, China's construction industry is quietly entering the era of refined management. Accurate estimation and cost control have become among the key considerations of the construction industry. For the calculation of engineering quantity, there are already many software devices that can be used for the calculation of engineering structure quantity, which means that the incorrect operation of personnel has been reduced to some extent, improving the work efficiency and measurement accuracy. The purpose of this paper is to solve the problems of computational missing, computational errors, inefficiency, data loss, and repetitive system in traditional computing based on the advantages of BIM computing system, which provide a reliable basis for cost forecasting and control. At the same time, using BMI calculation system to solve the problem of steel reinforcement in construction engineering, as well as the use of personnel, the existing calculation software still needs a lot of time and energy. We proposed a comprehensive evaluation study of reinforcement calculation in domestic construction engineering BIM calculation system based on a fuzzy comprehensive evaluation. This paper first summarizes the BIM calculation system of construction engineering, uses fuzzy comprehensive evaluation system as an important evaluation index system in domestic construction engineering BIM calculation system, through the judgment of various factors affecting the actual effect of the calculation system, and uses the fuzzy evaluation system combined with a case to demonstrate the superiority of the proposed research. Therefore, through the above research and experiments, it is concluded that the research method of this paper solves many problems in the process of engineering structure reinforcement calculation and provides a good reference method for the establishment of comprehensive evaluation system of reinforcement calculation, as well as providing an effective validation for the widespread use of BIM technology in the construction industry. Finally, it is also beneficial for users to comprehensively evaluate the BIM calculation system of the construction industry and provide a basic reference condition for different industries to use and choose BIM calculation systems.

The development of China's new urbanization has driven the rapid increase in large complex engineering projects, which have the characteristics of large-scale investment, long-term construction, and wide social influence, easily causing benefit conflicts among relevant stakeholders, and breaking out social stability risks. In the previous research, the risks of large complex engineering projects mainly concentrated on the assessment of economic risk, schedule risk, etc. However, there were few studies on social risks, and they did not consider how the risks spread on the complex networks based on the social connections such as interpersonal relationship. From the subject of social stability risk diffusion of large complex engineering projects, this paper constructs a related risk diffusion model based on the SIR model to analyze risk diffusion mechanism. through Net Logo simulation platform, the model is placed under a small-world network environment that is closest to the topology structure of real social interpersonal relationship network for simulation research, aiming to find out key factors of social stability risk intervention for large complex engineering projects, which greatly contributes to the social stability risk management of large complex engineering projects.

CO2 geological storage projects are an essential tool for China to achieve the double carbon target of energy savings and emission reductions. In order to safely and effectively control the implementation of injection projects and monitor the dynamics of CO2 injection, multi-dimensional and multi-disciplinary monitoring tools are required. Among them, microseismic monitoring is a key technology for predicting reservoir dynamics and reflecting reservoir geomechanical behavior. Such monitoring has been carried out previously for reservoirs in other countries, but experimental projects are also gradually being developed in China. In this paper, we focus on the research and analysis results of microseismic monitoring of carbon storage projects in various work areas. For different reservoir conditions, we explore combinations of the monitoring implementation methods in China, comparing the differences in each work area. We propose a joint well and ground microseismic monitoring method and a multi-spatial and multi-physical field coupling research system for use in the implementation of domestic demo projects for the future research and development of microseismic monitoring of carbon storage projects. The monitoring program can meet the requirements for certain periodic repeated or continuous observations and can intelligently assess the risk and handle the alert behavior. The foundation is laid for the development of the future microseismic monitoring technology to achieve the goal of developing cost-controllable, permanent, and real-time monitoring equipment. The application of the monitoring system in China has been effective, and this experience can contribute to the development of injection engineering in the future. [ABSTRACT FROM AUTHOR]

The author notes that the sciences are now something one must latch onto early and successfully as a teenager, and endure against all odds. This pivotal point requires maturity and even myopia--delayed gratification and voluntary dorkiness--traits not common in the young. As a nation, Americans are losing their hegemony in the sciences. In just the past decade, China quintupled its number of doctorates in engineering and the sciences, Korea and Taiwan doubled theirs, but the U.S. stayed stable. As individuals, Americans operate more and more contraptions, but understand them less and less. While there is no single solution to the problems of the STEM pipeline--where scientific interest is squelched over time and newcomers are barred from entry--the author offers a few thoughts.

Road recycling technology is gradually becoming a research focus in road construction due to natural resource shortages. It is therefore necessary to carry out deep and extensive analysis of the huge amount of publications in the research area of recycling technology in road construction. Based on three databases (Web of Science, Compendex and Scopus) and VOSviewer visualization software, this study conducts a bibliometric analysis of the literature in the field of recycled construction materials in pavement engineering. The global research publications were reviewed to quantitatively identify the literature characteristics. A number of publications, document types, research areas and keywords were used to achieve the general statistics of this reviewed literature. H-index, publication number and citations per publication were used to evaluate the academic contributions by country, institution and journal. The results show that the most productive country and institution for publications are the USA and Chang'an University from China, respectively, followed by China and Wuhan University of Technology. In recent years, researchers have generally paid attention to two main approaches: the application of rubber modified asphalt and the performance enhancement of recycled pavement.
