At present, teaching methods based on 2D drawings are still commonly used for educating students on the location of steel reinforcement bars in concrete. However, traditional teaching methods have limitations as students can find it difficult to understand 2D drawings. This study aims to develop an interactive and collaborative augmented reality environment (ICARE) using augmented reality (AR) technology to improve students' engagement in learning.

This study develops an ICARE prototype, which is organized into two stages: (1) The augmented teaching environment comprising of models and interactive components; (2) The AR collaborative application which uses Photon Unity Networking (PUN) plugin and Azure spatial anchors cloud service. The AR-based teaching environment runs with Universal Windows Platform (UWP) to enable development in the HoloLens 2 through Microsoft Visual Studio.

An experimental study was conducted, where 60 students were divided into three groups employing Drawings-based, building information modeling (BIM)-based and AR-based methods for teaching. After the test, the three groups of students were requested to complete a questionnaire. According to the analysis of the experimental results, the ICARE can improve students' comprehension, memory of learned materials and their ability to read and understand steel reinforcement drawings improving the quality of teaching, especially interactivity and engagement.

As illustrated in the experiments, the developed ICARE has outstanding performance over conventional approaches in civil engineering courses that can improve students' comprehension and memory of knowledge and their ability to read and understand steel bar drawings. This study provides empirical evidence that AR is a promising technology that can be integrated with traditional classroom instruction and can improve students' comprehension and memory of knowledge and their ability to read and understand steel bar drawings.

The purpose of this paper is to conduct a thorough study of the current research status and trends of Artificial Intelligence-Generated Content (AIGC), which is thriving and exerting significant influences on society, the economy and technology. This study will encompass both the ample opportunities and the array of emerging risks and challenges associated with AIGC. Furthermore, this paper seeks to propose practical optimization strategies to facilitate its continued development.

A total of 12,702 documents in Scopus, CNKI and Altmetric.com databases are analyzed in this paper. The visualization tools of CiteSpace and Netdraw are used to systematically analyze AIGC from macro, meso and micro perspectives based on bibliometric indicators. The analysis is combined with altmetrics indicators to identify hotspots in AIGC-related research and predict future development trends. Finally, substantive optimization suggestions for the development of AIGC are put forward.

Research has found that firstly, both domestic and international research in the field of AIGC is actively catching up with the pace of the era. Institutions and authors recognize the indispensability of collaboration, leading to the emergence of interdisciplinary cooperation trends. Secondly, at the thematic research level, both domestic and international studies cover the overall trends of AIGC, including technology, applications, challenges and coping strategies. However, international scholars tend to focus more on technological breakthroughs, while domestic researchers emphasize the formulation of national laws and regulations. Finally, through the analysis of hotspots and trends, it is predicted that future research will focus more on addressing the legal issues regarding the originality of AIGC, enhancing its interactivity, optimizing its applications, emphasizing ethical considerations and efficiently addressing major social issues such as pandemics using AIGC technology. Corresponding optimization strategies are proposed to ensure the development of AIGC is consistent with global consensus and values, creating a beneficial environment for its sustainable development.

Firstly, this paper integrates data from three databases and uses multiple software tools to conduct a comparative analysis of the research trends in AIGC from both domestic and international perspectives. Secondly, this paper not only analyzes the academic influence of AIGC-related research through bibliometric indicators but also combines altmetrics indicators to explore the public’s attitude toward AIGC. This method systematically reveals the overall development trends, leading institutions and researchers, thematic research areas, hotspot evolution and future development trends of AIGC-related research, providing theoretical references for subsequent scholars in AIGC research. Additionally, this paper helps governments, institutions and organizations to precisely and wisely formulate policies and investments, as well as to effectively comprehend the development trends of AIGC and promote the advancement of AIGC technology and applications.

This study aims to examine aspects of the construction of professional identity, based on an interpretative inquiry in two Chinese professional service firms in Beijing.

Data were gathered through participant observation, archival material and interviews. The interpretive nature of the research experience facilitated openness to the local field and avoidance of a heavy reliance on assumptions that derive from privileging the Western constructions of professional identity, where “I” (the researcher) am situated epistemologically.

Professionalism discourse, a powerful resource of ambiguity, becomes an arena where identity is “asserted” through organisational performance, incorporated in normative Western‐driven laws. Enacted professionalism appears consistent with the pursuit of an elevated Western image. The relationships with the clients, however, are embedded in guanxi dynamics and related accountabilities, reflecting the local ways of doing things.

Empirical material offers insights into professionalisation processes in Chinese firms, with a focus on the construction of professional identity, located within organisational micro‐dynamics.

The purpose of this paper is to exhibit performance evaluation research science and technology (S&T) policy in strengthening economic growth of Chongqing. Chongqing is the only one municipality in western China, and its S&T development absolutely will affect other fields to carry on in the whole nation. This research will offer a framework of S&T policy performance evaluation for the strategic management of S&T policy in Chongqing.

This paper uses data envelopment analysis (DEA) and grey relational analysis (GRA) to measure up S&T policy performance evaluation in Chongqing based on data from 2007 to 2012.

The key finding is that only S&T policy DEA value in 2008 is invalid, and four input factors and six output factors strongly relate to S&T efficiency.

Policy makers should focus on S&T policy performance and evaluate it with the scientific method to stimulate S&T's healthy development.

The paper gives an insight into the perspectives of input–output of S&T efficiency in Chongqing and forms an evaluation system which will benefit policy formulation and implement in the future.

In these times of globalisation, distances are getting smaller, enhancing the interactions between people of different cultural backgrounds. This is especially true in the area of tourism, a field that is shaped by manifold communication activities. The enormous increases in the numbers of Chinese tourists visiting Europe and other Western destinations require building up intercultural competencies to minimise conflicts and promote mutual understanding. It is therefore necessary to question one’s own cultural view, which is why the debate surrounding de-Westernisation is of crucial importance. The metaphor of the atmosphere – in Chinese qifen – offers a helpful access point to strengthen mutual understanding, because it creates a bridge between eastern and western thinking. Paul Watzlawick (1967) developed his well-known five axioms of communication, the second of which states that every communication has both content and a relational aspect, and the latter classifies the former. This chapter shows why the atmospheric dimension of communication should be established as the third axiom in order to understand communication holistically.

The study aims at disclosing the evolution process to an entrepreneurial university in the government‐pulled triple helix in China through the analysis of MIT and Stanford model of “university‐pushed triple helix” in which academic institutions take the lead in regional innovation.

The paper is based on a case study of the Northeastern University (NEU), which is located in the Northeast China where there is a dominant government‐pulled triple helix and with the establishment of China's first science park in which a highly successful software company (Neusoft) was created.

The pathway to an entrepreneurial university begins with government‐pulled + industry‐university collaboration, to university‐industry collaboration + interaction triple helix. This may be followed by a gradually developing “university‐industry collaboration” in which companies fund academic research with potential industrial use, the beginnings of a university‐pushed triple helix.

The analysis of NEU exemplifies the emergence of the entrepreneurial university in China and provides strategic implications for policy makers in terms of designing the appropriate policy to support university enterprising strategy.

This paper aims to conduct an in-depth analysis of the shortcomings of apps’ privacy policies and to propose improvement and optimization strategies, which are of great significance for establishing a transparent and responsible privacy protection framework that ensures compliant collection and use of users’ information and effective protection of their privacy.

This paper obtained privacy policy texts for 100 shopping apps through Web crawlers and manual downloads. Based on the perspective of perceived usefulness, thematic analysis is conducted through the latent Dirichlet allocation topic model and comparison with existing policies. Based on the perspective of perceived ease of use, readability analysis is conducted through content analysis and formula calculation.

The apps privacy policies can be divided into seven themes. The authors benchmark these seven topics with the Personal Information Protection Law of the People’s Republic of China, the E-Commerce Law of the People’s Republic of China and the General Data Protection Regulation. It is found that there are omissions in the information collection and use and juvenile protection of the existing apps. Through the indicators’ readability analysis and calculation, it is found that the existing apps privacy policies have good performance in the readability indicators such as naming method, frame directory and so on. However, text personalization and text readability need to be improved and optimized.

At the theoretical level, this paper constructs a model from the dual perception perspectives of perceived usefulness and perceived ease of use and analyses the apps’ privacy policy texts at a fine-grained level. At the practical level, based on large-scale apps’ privacy policy text data, this paper conducts multi-dimensional research from theme analysis, authoritative law benchmarking analysis, content analysis and text readability calculation and analysis. At the same time, this paper identifies the current problems of apps’ privacy policies and puts forward countermeasure suggestions for their content improvement and optimization.

This paper aims to prepare Poly(Styrene-Butyl acrylate-Methacrylic acid) @Poly Gallic acid-Fe³⁺ photonic crystal composite inks [P(St-BA-MAA)@PGA-Fe³⁺ PCCI, @ means the PGA-Fe³⁺ is loaded on the microspheres] and construct noniridescent structural colors on fabric substrates, with the goal of improving the visibility of structural colors.

P(St-BA-MAA)@PGA-Fe³⁺ PCCI were prepared by coating P(St-BA-MAA) microspheres with a metal-polyphenol network formed by gallic acid (GA, C₇H₆O₅) and Fe³⁺. The assembly effects of the inks were explored under different conditions, including pH, temperature, concentration and surface tension. The optimal self-assembly conditions of the inks were determined using the controlled variable method.

The results demonstrated the successful preparation of P(St-BA-MAA)@PGA-Fe³⁺ PCCI. The metal polyphenol network film composed of GA and Fe³⁺ was successfully coated on the surface of P(St-BA-MAA) seed microspheres. The assembly mechanism of the inks was investigated, indicating that at a diethylene glycol (DEG, C₄H₁₀O₃) concentration of 0.3 wt% and pH of 7, bright noniridescent structural colors could be formed on fabric surfaces after self-assembly by PCCI at 60 °C for 10 min. Furthermore, the mechanical fastness of the structural colors was enhanced due to the adherence of the soft shell composed of P(St-BA-MAA) and GA.

Utilizing a cost-effective approach and a diverse array of readily available raw materials, we have successfully prepared P(St-BA-MAA)@PGA-Fe³⁺ PCCI, which boasts superior performance and offers fabrics a range of unique coloring styles. This innovation paves the way for potential applications of structural colors in practical production, thereby broadening their realm of utility.

As to different angles of attack and nonlinear problems caused by high temperatures in coexisting hypersonic aircraft, people mainly rely on fluid software for research but lack analysis of flow mechanisms. Owing to computational difficulties, few people use numerical algorithms to combine them for discussion. Hence, this study aims to make a deep inquiry into the laminar flow and heat transfer of compressible Newtonian fluid in hypersonic aircraft with small attack angles.

In this paper, on the basis of mass, momentum and energy conservation laws, the governing equations of the hypersonic boundary layer are established. Viscosity, specific heat capacity and thermal conductivity are considered nonlinear functions concerning temperature. In virtue of the MacCormack finite difference method, the stationary numerical solutions are solved directly, and the validity of the algorithm is verified.

The results demonstrate that at Mach number 5, compared to the 0° attack angle, the maximum temperature near-wall at the 3° attack angle increases by about 25%. An enjoyable phenomenon is discovered, where the position corresponding to the maximum wall shear force shifts back as the attack angle and Mach number increase. The relationship between the near-wall maximum temperature versus attack angle and Mach number is fitted through numerical calculation results.

Empirical formulas can be used to estimate heat transfer characteristics at small attack angles, which will guide the design of aircraft thermal protection systems.

With the increasing prevalence of social media in everyday life, scholars have argued the need of exploring enterprise social media (ESM) for workplace outcomes. This study investigates the relationship between ESM use and organizational learning capability (OLC) by focusing on the mediating role of informal learning (INFL) and the moderating role of social capital (SC).

The paper developed and tested a mediated moderated model explaining the impact of ESM on OLC. The study used temporally separated data of 281 respondents collected in two waves from firms in India that use organizationally facilitated ESM platforms for internal workplace communication.

An analysis of temporally separated two-wave data indicates that INFL mediates the relationship between ESM use and OLC. Also, SC is found to moderate the effect of ESM use on INFL, and INFL mediated the moderation effect of SC on relationship between ESM use and OLC such that the relationship will be stronger when employees have a higher rather than lower level of SC.

The study theoretically contributes and extends the literature on ESM and learning in organizations. The study provides important practical implications to support and institutionalize learning at work. The results of the study provide evidence that ESM are not just networking tools but a platform for learning. Findings of the study suggest that ESM can be one such tool to promote and capture employee INFL. The results also show that SC plays a critical role in predicting the extent to which employees learn informally using ESM, thereby building OLC. This result suggests that organizations should make conscious and concerted efforts to build employee SC. The above findings also have interesting implications for learning and development (L&D) and information technology (IT) managers who wish to implement technology for collaborative purposes.

Addressing the underlying processes that explain how ESM positively influence OLC was highlighted as a critical research gap that needs attention. The paper is novel in its approach as it provides empirical evidence for the relationship between ESM and its impact on employee outcomes, an area pertinent in today's digital economy, however, received sparse attention by management scholars so far. It also provides empirical grounds toward a meaningful shift in the social media discourse – transition from being traditionally viewed primarily as “a networking platform” to “a learning platform.”
