This study aims to investigate users’ adoption of bike sharing systems in China.

This research combined perceived risk factors with existing technology diffusion theories (e.g. technology acceptance model and unified theory of acceptance and use of technology) to develop a research model to examine users’ adoption of bike sharing systems in China. As a result, a research model with 11 hypotheses was developed. The developed research model was empirically tested using data collected from a survey of 298 users in China. Structural equation modeling was used to analyze the collected data.

The findings indicated that perceived usefulness, facilitating conditions and perceived risks were important determinants to the adoption of bike sharing systems. However, perceived ease of use and social influence did not have significant positive impacts on users’ behavioral intention to use bike sharing systems.

It is important for service providers to dedicate their time and efforts in maintaining and repairing bikes to ensure that the bikes are in a good condition to be used. System providers need to work on good solutions to better protect users’ personal information and location information.

This study is first of its kinds in investigating the adoption of bike sharing systems by combining technology diffusion theories and perceived risk theory in China.

Sluggish performance in construction productivity (CP) is a common occurrence worldwide. This phenomenon is also observed in Singapore. In this context, the role of trade unions (TUs) has also been mentioned but appears to be little understood. Hence, this study evaluates the role of TUs in contributing to CP. The key issue is to determine whether TUs have a role to play in contemporary society in improving CP.

This study takes on multiple research methodologies; more specifically, the mixed-method of survey questionnaires and interviews is used. Firstly, a survey questionnaire was employed to obtain broad viewpoints on the general understanding of the target groups towards the CP issues in Singapore. The survey questionnaire also attempts to study the TUs in greater depth by examining their existing strategies of and hindrances to improving CP. Once findings were gathered from the survey questionnaire, the interviews were carried out to probe deeper into the phenomena in the results.

The research findings showed there is a generally positive outlook that TUs have the ability to contribute to CP. The study finds that the TU respondents possess strong attributes within the normative pillar, but weak attributes in the regulative and cultural–cognitive pillars.

This study uses the Institutional Theory as a general framework, which identifies a union's functions and activities in three pillars that underpin the institutional theory and defines its impact on construction productivity.

The purpose of this paper is to investigate what role literature-based inputs have on the information security policy (ISP) development in practice.

A literature review is carried out to identify commonly used inputs for ISP development in theory firstly. Secondly, through the lens of institutional theory, an interpretive approach is adapted to study the influence of literature-based inputs in the ISP development in practice. Semi-structured interviews with senior experienced information security officers and managers from the public sector in Sweden are carried out for this research.

According to the literature review, 10 inputs for ISP development have been identified. The results from the interviews indicate that the role inputs have on the ISP development serves as more than a rational tool, where organisational context, institutional pressures and the search for legitimacy play an important role.

From the institutional perspective, this study signifies the influence of inputs on ISP development can be derived from institutionalised rules or practices established by higher authorities; actions and practices that are perceived as successful and often used by other organisations; the beliefs of what is viewed as appropriate to meet the specific pressures from stakeholders.

This research recommends five practical implications for practitioners working with the ISP development. These recommendations aim to create an understanding of how an ISP could be developed, considering more than the rational functionalist perspective.

To the best of the authors’ knowledge, it is the first of its kind in examining the role of literature-based inputs in ISP development in practice through the lens of institutional theory.

The purpose of this paper is to investigate the challenges of using ICT in secondary schools in Sweden from teachers’ perspectives.

The research followed a qualitative research approach. First, a conceptual framework was developed based on previous research. Then, four teachers, teaching in six different subjects in secondary schools in Sweden, participated in semi-structured interviews that consisted of open-ended questions exploring their views on the challenges of using ICT in secondary schools.

According to the results, the authors found that the biggest challenges were associated with the perspective of teaching and teaching preparation. Most challenges from previous research have been re-confirmed by the interviewees in this study. In addition, some new challenges were identified in this study. For instance, the results indicated that it was time consuming to find plagiarism of students’ exercises, and there was a lack of ICT training of digital resources provided by the schools.

The investigation of using ICT in secondary schools is of scientific significance because it enriches the understanding of strengths and challenges of using ICT in educational activities. In particular, this research aims to shed light on challenges that teachers may face when using ICT in secondary schools. This research can also contribute to making future strategic plans for the use of ICT in secondary schools.

This paper aims to propose a conceptual model of policy components for software that supports modularizing and tailoring of information security policies (ISPs).

This study used a design science research approach, drawing on design knowledge from the field of situational method engineering. The conceptual model was developed as a unified modeling language class diagram using existing ISPs from public agencies in Sweden.

This study’s demonstration as proof of concept indicates that the conceptual model can be used to create free-standing modules that provide guidance about information security in relation to a specific work task and that these modules can be used across multiple tailored ISPs. Thus, the model can be considered as a step toward developing software to tailor ISPs.

The proposed conceptual model bears several short- and long-term implications for research. In the short term, the model can act as a foundation for developing software to design tailored ISPs. In the long term, having software that enables tailorable ISPs will allow researchers to do new types of studies, such as evaluating the software's effectiveness in the ISP development process.

Practitioners can use the model to develop software that assist information security managers in designing tailored ISPs. Such a tool can offer the opportunity for information security managers to design more purposeful ISPs.

The proposed model offers a detailed and well-elaborated starting point for developing software that supports modularizing and tailoring of ISPs.

The purpose of the research is to investigate users’ adoption of blockchain-based games in China.

This research applied existing technology diffusion theories to develop a research model to examine users’ adoption of blockchain-based games. As a result, a research model with nine research hypotheses was developed. The developed research model was empirically tested using data collected from a survey of 210 blockchain-based games users. Structural equation modeling was applied to analyse the collected data.

The results indicated that seven of nine research hypotheses were supported. It was found that trust, perceived usefulness, perceived enjoyment and perceived ease of use were key determinants for users’ behavioural intention to use blockchain-based games. The most influential relationship in the research model appeared to be the effect of perceived usefulness on users’ behavioural intention to use blockchain-based games. However, subjective norms did not have significant positive impacts on users’ behavioural intention to use blockchain-based games.

The regulatory support from governmental authorities is essential to provide additional legal certainty to build users’ trust in playing blockchain-based games. Blockchain-based games providers should arrange the training program targeted to the general users to enhance their understanding of the key features associated with blockchain-based games. Blockchain-based games developers should come up with good design solutions to maximize user enjoyment with blockchain-based games by considering additional entertainment elements.

To the best of the authors’ knowledge, this study is first of its kind in investigating the adoption of blockchain-based games from users’ perspectives. This study contributes to the existing literature on the adoption of blockchain technology.

Building information modelling (BIM), lean construction (LC) and prefabricated housing construction (PHC) have individually aroused great attention from academia and industry. However, the integration of LC and BIM in PHC projects has not been sufficiently explored. This study aims to assess the current status of the implementation of BIM and LC in China’s PHC sector given, firstly, that China is a developing country characterised by the world’s largest population and a huge housing market, and secondly, that although China’s PHC is strongly supported by the government, the adoption of BIM and LC in PHC varies.

A mixed approach (questionnaire survey and interviews) is adopted in this study. A total of 127 valid questionnaires were collected. This is followed by interviewing 12 interviewees who are key stakeholders in PHC and hold managerial positions.

The findings of the questionnaire survey show that BIM is more prevalent than LC in PHC projects in China. In addition, the adoption of LC exhibits more maturity in stages associated with production and manufacturing, and logistics and transportation, whereas BIM has seen wider adoption in design and construction. The interviews validated the factors that influence the implementation of BIM and LC in PHC projects in China.

The study uses a strengths, weaknesses, opportunities and threats analysis framework to clarify the opportunities, threats, strengths and weaknesses of BIM and LC in China’s PHC and proposes strategies.

The Toyota Way was developed as an efficiency framework to streamline Toyota Motor Corporation’s operational procedures. The collection of Toyota Way principles is often termed “lean”. Over the last few years, nonmanufacturing organisations have begun to recognise the value and applicability of lean methods for their operations. Architectural and engineering design (AED) firms are no exception. This study aims to explore the perspectives of employees at AED firms on the implementation of lean production principles (LPPs) into their operations. Due to the limited resources available to facilitate our measurement of employees’ views regarding the adoption of lean approaches, this study adopts a more scoped approach to employees’ perceptions of these principles within AED firms.

Fifty-two respondents participated in the survey. The interviewees were from firm A and firm B, an architecture firm and an engineering firm, and were chosen to help us gain a more in-depth understanding of their views regarding the LPPs.

Our study indicates that AED offices were unfamiliar with the concepts of lean principles, even though they were aware of its importance in their daily operations. Despite their scepticism about the implementation of lean concepts, some lean principles are implemented in their own fields of work.

This study complements earlier work on lean design that investigated the use of a particular lean technique by looking at the lean principles where some are implemented to a large extent, and some are not.

The rise of artificial intelligence (AI) and differing attitudes towards its adoption in the building and environment (B&E) industry has an impact upon whether companies can meet changing demand and remain relevant and competitive. The emergence of Industry 4.0 technologies, coupled with the repercussions of COVID-19, increases the urgency and opportunities offered that companies must react to, as disruptive technologies impact how project management (PM) professionals work and necessitate acquisition of new skills. This paper attempts to identify the drivers of and barriers to, as well as the general perception and receptiveness of local PM professionals towards, AI adoption in PM and thereby propose potential strategies and recommendations to drive AI adoption in PM.

This study employs both quantitative and qualitative approaches to examine the findings gathered. A survey questionnaire was used as the primary method of gathering quantitative data from 60 local PM professionals. Statistical tests were performed to analyse the data. To substantiate and validate the findings, in-depth interviews with several experienced industry professionals were performed.

It is found that top drivers include support from top management and leadership, organisational readiness and the need for greater work productivity and efficiency. Top barriers were found to be the high cost of AI implementation and maintenance and the lack of top-down support and skilled employees trained in AI. These findings could be attributed to the present state of AI technologies being new and considerably underutilised in the industry. Hence, substantial top-down support with the right availability of resources and readiness, both in terms of cost and skilled employees, is paramount to kick-start AI implementation in PM.

Little research has been done on the use of AI in PM locally. AI's potential to improve the productivity and efficiency of PM processes in the B&E industry cannot be overlooked. An understanding of the drivers of, barriers to and attitudes towards AI adoption can facilitate more intentional and directed oversight of AI's strategic roll-out at both the governmental and corporate levels and thus mitigate potential challenges that may hinder the implementation process in the future.

Due to the fragmented and complex nature of the construction industry, many countries, including Singapore, have progressively encouraged greater collaboration amongst major stakeholders in the industry. It is hoped that doing so will result in an increase in the quality of construction projects. Given the long duration of typical construction projects, it is plausible for collaborating parties to develop close and personal relationships. In recent years, corruption cases arising from familiar collaboration have caught the public's attention. This study seeks to better understand familiar collaboration and its adverse impacts on the quality of construction projects.

A mixed research method was adopted, with a questionnaire survey distributed to 32 respondents representing client and contractors. This was followed by interviews to validate the survey findings.

The findings suggest that, when there is a lack of surveillance, familiar collaboration is likely to lead to favouritism and dishonesty, which can have an adverse impact on the quality of construction projects. The findings additionally suggest that value for money, conformance to specifications and fitness for purpose are the main aspects of quality that are likely to be adversely affected by corrupt practices bought about by familiar collaboration.

In this paper, these relationships are described using the term familiar collaboration. Strong and intimate relationships of this type may lead to a danger of parties committing corrupt practices. This study is one of the very attempts seek to better understand familiar collaboration and its adverse impacts on the quality of construction projects.
