This paper aims to present a longitudinal and visualising study using bibliometric approaches to depict the emerging trends and research hotspots within the mobile information system domain.

Publications included in the Web of Science (WoS) database for 2001–2021 are reviewed and analysed on various aspects through coauthorship, cocitation and co-occurrence analysis. The analyses are conducted using VOSViewer, a scientific visualisation software program.

Academic publications related to mobile information systems fluctuated at a low level during the initial part of the 21st century and have grown rapidly in number in the past decade. The USA and China are the leading contributors to these publications and hold dominant positions in the obtained collaboration network. Computer science, engineering and telecommunications are the top three research areas in which mainstream mobile information system research occurs. Moreover, medical informatics and health-care science services have gradually become new research hotspots.

This study provides a systematic and holistic account of the developmental landscape of the mobile information system domain. This study provides a good basis for analysing the evolution of research in mobile information systems and may serve as a potential foundation for future research.

This study, based on construal level theory, aims to examine the influential mechanism of leader empowerment behaviour on employee creativity. Specifically, it examines the mediating role of cognitive flexibility between leader empowerment behaviour and employee creativity, along with the moderating effect of consideration of future consequences (CFC) on this linkage.

A two time-point survey study (n = 214) was conducted to collect information from leaders and employees in terms of mutual evaluation in several Chinese industries. To effectively avoid common source bias, this survey was conducted through pairing leaders and employees. During the survey, the supervisors and subordinates were double-blinded. Correlation analysis and hierarchical regression analysis were used to test the research hypotheses.

Firstly, leader empowerment behaviour can significantly predict employee creativity. Second, cognitive flexibility plays a partial mediating role in the linkage between leader empowerment behaviour and employee creativity. Thirdly, CFC moderates the relationship between leadership empowerment behaviour and cognitive flexibility. The mediating role of cognitive flexibility underlies the overall moderating effect of CFC on the relationship between leader empowerment behaviour and employee creativity.

We used construal level theory to explain the influence of the mechanism of leader empowerment behaviour on employee creativity. In this manner, this study bridges the gap between theory and practice, as well as enriching the research on leader empowerment behaviour and employee creativity, especially in the Chinese context. Moreover, our study has several practical managerial implications, based on the importance of employee creativity. It inspires the implementation of leader empowerment behaviour, cultivation of employee creativity and introduction of several procedures.

This paper discusses the influential mechanism of leader empowerment behaviour on employee creativity from a new perspective and explains the process of encouraging employee creativity through information-processing methods. It mainly highlights the application of construal level theory to discuss employee creativity and develops a new research frame for employee creativity. Leaders can raise employee creativity through leader empowerment behaviour.

The former residences of historical figures are typical landscape elements of historic districts, which are characterised by the styles of these residences and spiritual historical figures cultures. The purpose of this paper is to determine how the former residences respond once the historical figures living there have passed.

The history of human culture and progression of urban construction – which are submerged in societal transformation – is recorded for old Beijing city. Narrative space theory is used and methods such as a content analysis, map overlay and the Geographic Information System are employed to analyse the selected 300 former residences of historical figures in old Beijing city.

The results are as follows: the political setting played a key role in the evolution process, three political narrative areas in the inner city and one cultural narrative area in the outer city form the narrative spatial structure of the former residences of historical figures, “government construction” and “resident construction” are the main reasons for the loss and destruction of narrative spaces and ordinary life is an important channel for showcasing the history of former residences. The narrative spaces of these residences carry double histories, namely, the development of human history and of city construction.

Different from former studies that focus on the preservation of the single historical building, this study explores the integral logic of historic buildings in the whole city through narrative space theory to get a combination of culture and space.

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.

The purpose of this paper is to analyze and compare the costs of price and income subsidies when the food security policy targets the urban poor. The result may help policymakers choose a desired subsidy scheme to ensure food security for the urban poor facing food price surge.

The analysis consists of three parts: constructing an empirical model on provincial panel data in 1993‐2009 estimating the impact of grain price on food security among urban residents by different income level; evaluating the potential costs of shifting to income subsidy aiming to maintain the real income levels of the low income, lowest income or the poor residents if grain price increases by 20 percent; and comparing with the cost of price subsidy to achieve the same policy goal.

The paper finds that, food price surge will hurt the urban poor much more seriously than the high income population; the rich residents may receive more benefit from price subsidy; and income subsidy has obviously a cost advantage while the targeted people benefit more.

The obvious value of the paper is to show that income subsidy is much more desired than price subsidy, if the policy goal is to help the poor during food price surge.

This study aims to make the mobile robot better adapt to the patrol and monitoring in industrial field substation area, a multi-mode mobile carrying mechanism which can carrying data collector, camera and other equipment is designed.

Based on the geometric axis analysis and interference analysis, the multi-mode mobile carrying mechanism is designed. The screw constraint topological theory and zero-moment point (ZMP) theory is used to kinematic analysis in mechanism mobile process.

The mobile carrying mechanism can realize the folding movement, hexagonal rolling and quadrilateral rolling movement. A series of simulation and prototype experiment results verify the feasibility and actual error of the design analysis.

The work of this paper provides a mobile carrying mechanism for carrying different data acquisition equipment and surveillance camera in industrial field substation zone. It has excellent folding performance and mobile capabilities. The mobile carrying mechanism reduces the workload of human being and injuries suffered by workers in industrial substation area.

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.

The purpose of this study is to obtain a titanium mandibular implant that possesses a personalized external shape for appearance recovery, a supporting structure for physiological loading and numerous micro-pores for accelerating osseointegration.

A three-dimensional intact mandibular model of a beagle dog was created from cone-beam computerized tomography scans. A segment of the lower jaw bone was resected and replaced by a personalized implant with comprehensive structures including a customized external shape, supporting structures and micro-pores, which were designed by topology optimization. Then with FEM analysis, the stress, displacement distribution and compliance of the designed implant were compared with the non-optimized model. The weight of the optimized implant that was fabricated by SLM with titanium alloy powder was measured and contrasted with the predicted non-optimized model for evaluating the viability of the design.

The FEM results showed the peaks of von Mises stress and displacement on the optimized implant were much lower than those of the implant without optimization. With topology optimization, the compliance of the implant decreased significantly by 53.3 per cent, and a weight reduction of 37.2 per cent could be noticed.

A design strategy for personalized implant, with comprehensive structures and SLM as the fabrication method, has been developed and validated by taking a canine mandible as the case study. With comprehensive structures, the implant presented good biomechanical behaviors thanks to the most appropriate supporting structures obtained by optimal design. The topological optimal design combined with SLM printing proved to be an effective method for the design and fabrication of personalized implant with complex structures.

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.

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.”
