This paper aims to describe the deployment of an e‐learning environment for construction courses based on enhancing virtual computing technologies using agent‐based techniques.

This research involves designing and deploying a complex application that combines advanced visualisation, interactive management through complex virtual devices, distributed multi‐user communication and intelligent components. The proposed agent‐oriented methodology and resulting application organises construction knowledge into a structure that enables the students to undertake more self‐directed, systematic and scientific exploration.

There is great potential for experimenting with a wider variety of educational technologies such as “intelligent” virtual environments. This is a concept that needs further experimentation within construction courses to enrich students' learning with practice‐based experiences. The use of ageny‐oriented objects within simulations and modeling make the virtual learning environment a highly interactive experience. Attempts to do this using traditional intelligent tutoring systems have been frustrated by integrations challenges. Agent‐based systems can handle such challenges. The agent approach is also more efficient in analysing the impact of different decisions in various scenarios by automating the execution of repetitive, time‐consuming actions.

This research identifies specific gaps in the existing e‐learning infrastructure that can be addressed using the intelligent agent paradigm. In particular, the research demonstrates how the notion of learning by actively exploring and controlling environmental variables can be best utilised in the selected domain by giving the learners the means to rapidly visualize the effects of their decisions.

Construction disciplines have increasingly embraced the use of advanced visualisation applications and display systems that allow students to gain a better understanding of the construction process and the resulting facility's performance. Existing efforts are based on image visualisation or animation detailed using, for example, Virtual Reality Modeling Language and 3D Studio Max‐based design animations and walkthroughs. None of these efforts has explored the use of an agent oriented, virtual tutoring approach. A comprehensive literature review established that of no formalised methodologies exist for deploying agent‐based virtual learning environments.

This paper aims to describe the characteristics of virtual environments (VEs) that reinforce internationalization and to explore further implications for their utilization. Internationalization at universities is often argued as being key to developing global citizens. The use of VEs for global experiences is a relatively new phenomenon for universities. Understanding the aspects of VEs that develop global citizens will assist in their further development for internationalization.

The paper presents a case study comparison of students and their experiences in the real world and VEs used in the Monash University Chinese Studies program. The student participants were interviewed using semi‐structured questions to establish the elements of the Monash Secondlife© Island contributing to their understanding of internationalization.

The case study concludes that students perceived the Monash Secondlife© Island useful for basic interactions in language learning and for students less confident with social interaction. Another outcome is the indication that students desire more technology (e.g. voice) to be used in subsequent developments.

The paper provides a unique analysis of the utilization of VEs to develop internationalization at university. It outlines the characteristics expected as part of internationalization, the current usage of VEs to develop internationalization, and articulates the specific characteristics that VEs enable as part of the internationalization process.

This study aims to investigate the relationship between different organisational development programmes (360-degree feedback; Coaching; Job assignment; Employee assistance programmes; On-the-job training; Web-based career information; Continuous professional development; External education provision) and employees’ career development. The implications of the moderating effects of gender on the relationships between these eight organisational programmes and career development are assessed.

To examine hypothesised relationships on eight organisational programmes and career development, this paper computed moderated regression analyses using the PROCESS macro (3.5), for a two-way analysis of variance (Hayes, 2018). The data collected are based on a survey sample of employees (n = 322) working in Scotland.

Two main findings arose from this empirical study. First, there are significant direct relationships between seven out of the eight organisational development programmes and their influences on employees’ career development. Second, gender is a significant moderator for four of the programmes’ relationship with career development, namely, coaching, web-based career information, continuous professional development and external education provision. However, gender failed to moderate the four other programmes’ (i.e. 360-degree feedback, job assignment, employee assistance programmes and on-the-job training) relationship with career development.

This paper concludes that closer attention should be given to the organisational design of these development programmes and consideration of potential gender differences in employees’ perception of their importance for career development in their organisation. To date, the majority of research in the literature has concentrated on the impact of training on career development, so this study contributes to the body of knowledge on a set of organisational development programmes and their effect on career development moderated by gender.

The purpose of this paper is to develop a multi-agent-based model for quantitatively measuring how the design change management strategies improve project performance.

Based on questionnaires and interviews, this paper investigates the coordination mechanism of risks due to design changes in prefabricated construction (PC) projects. Combined with all the variables related with design change risks, a multi-agent-based simulation model is proposed to evaluate the design change management effect.

The coordination mechanism between design change factors, design change events, risk consequence and management strategy in PC projects is described and then the simulation-based design change management mechanism in PC projects is used to assess the effect of management strategies under dynamic scenarios.

PC projects have rapidly increased in recent years due to the advantages of fast construction, high quality and labor savings. Different from traditional on-site construction, the impact and risk from design changes are likely to be greater due to the prefabricated project being multi-stage, highly interactive and complex. The simulations presented in this paper make it possible to test different design change management strategies in order to study their effectiveness and support managerial decision making.

Coaching for teachers has evolved as a form of professional development. The benefits of such interventions have been examined with regard to student, teacher and school outcomes, but the purpose of this paper is to present an investigation relating to the benefits of instructional coaching (Knight, 2006) to teachers as perceived by the teachers themselves.

The study utilises a subjectivist approach with a constructivist paradigmatic stance (Morgan and Burrell, 1985). Eleven semi-structured, face-to-face interviews were conducted (King, 2019) with teachers at a secondary (high) school in the UK. The data were interpreted and analysed using thematic analysis (Braun and Clark, 2006).

The research suggests the following four benefits to the teachers who participated in the study, which aligned well with the literature review: improved relationships, awareness, reflectiveness and enhanced practice. A fifth perceived benefit reported by the participants was positive attitude, which captured a sense of increased confidence, motivation and positivity.

Findings were based on the self-reported data of a small sample. Therefore it is not possible to generalise the findings but Thematic Analysis was used to understand perceptions and insights in a wider context (Ritchie and Lewis, 2003). This research builds on the literature focusing on perceived benefits to teachers. Findings generally support current theoretical understanding. The results of this exploration of the teacher perception of benefits of instructional coaching in one UK school contributes to the emerging literature about the benefits of coaching. The teacher perceived benefit of positive attitude does not appear to be identified in the literature.

In practice, this study raised awareness of the possible benefits of coaching to educators. The authors recommend that educators, policymakers and educational leaders should further explore the potential benefits of coaching in education settings. Utilising teacher perception, the study further confirms coaching to be a useful way of supporting educators to enhance their practice.

This paper fulfils an identified need to gain a better understanding of teacher-perceived benefits of coaching. This understanding will support school leaders and policymakers who may be considering how to best leverage coaching in educational settings.

This paper aims to present an off-site construction (OSC) readiness maturity model for assessing the readiness of offsite construction companies in the Indian construction sector.

The research was conducted in three stages. The first stage consisted of a detailed literature review to document 17 different variables affecting the OSC adoption in India. In Stage 2, 15 semi-structured interviews were carried out where the participants were asked to refine those variables for the Indian context and define what would be different levels of attainment. In the third stage, another set of 5 semi-structure interviews was performed to validate the maturity levels and definitions.

A three-level OSC readiness maturity model is presented for discussion. This describes 17 variables at different levels of maturity.

The proposed OSC readiness maturity model guides construction practitioners in India through a structured process to enable them to assess their OSC readiness in the market. This assessment enables them to evaluate and benchmark their processes through the strategic and operational phases. The maturity model also identifies the areas of concern and the scope for further development or change to secure the optimal advantage of OSC methods.

The research produced a model to assess the readiness of OSC adoption in the Indian construction sector. Although the model has been applied to the Indian construction sector, it can easily be modified to accommodate other OSM contexts.

The purpose of the paper is to discuss the scope for improving the delivery of FM services through the use of wireless web‐based communications infrastructure, delivered via an application service provider (ASP) business model. This paper discusses the findings from case studies of three organisations and their approach to the management of facilities.

An investigation was undertaken to ascertain the current state of play in terms of managing and tracking processes within the facilities management department of three different organisations. These case studies were chosen from distinct sectors, namely health care, higher education, and banking. Emphasis is placed on analysing how the organisations currently operate with their existing FM systems and the degree of influence technology has on existing processes. This was considered mainly in terms of computer‐aided facilities management (CAFM) and computer‐integrated facilities management (CIFM).

The study found that a new wireless web‐based service for FM systems would be considered useful. Although notoriously slow adopters of new technology, there was an acceptance by the facilities managers interviewed that a wireless web‐based approach would improve current practice, especially with respect to real‐time job reporting and tracking and in the determination of FM operative working time utilisation.

Further work by the author is focusing on the development of a suitable demonstrator to illustrate the key concepts of a wireless web‐based FM service which will then be tested and evaluated. For further information, visit the research project web site at www.wirelessfm.org Originality/value – The paper hopefully stimulates discussion in the area of emerging wireless technologies that have the potential to streamline and improve current practices for the management of facilities, in particular that of real‐time job reporting and tracking.

Construction projects have become larger and more complex and yet still maintain a high drive for quality. As a result of this increase in size and complexity, the quantities of documentation and information required to control the overall project process have themselves become more complex. Underpinning the goal of construction quality is real time information flow to and from the construction site along with communications between all the parties involved. Project information integration and collaboration is the key to achievement of coherent quality management and this can be attained through electronically sharing of information during the construction process. The residential sector of the construction industry continually experiences significant numbers of “snags”. Many site issues including snagging need to be resolved quickly and efficiently to avoid dispute and more importantly cost overrun. However, the distinct professions and artisans within the industry rarely acknowledge the needs of others. Indeed the snagging information they produce is often so incompatible that the next stage in many processes is to reconstruct the information into a workable format. Analysis of a range of organisations' approaches to snagging shows that they have their own distinct snagging process. What is required is a coherent approach to the use and implementation of an IT based, industry wide, snagging format which would revolutionise and streamline the recording and approval process of construction snagging.

The aim of this paper is to provide a review of state-of-the-art literature on information sharing in the context of African perishable agri-food supply chains (AFSCs). In doing so, the authors hope to stimulate further research and advance both theory and practice on African perishable AFSCs, which is a relevant, but under-investigated context.

The authors’ systematic literature review covers a period of 21 years (2000–2021). After providing the bibliometric and methodological insights related to this sample of literature, the authors provide a detailed analysis and discussion of the key aspects of information sharing in African perishable AFSCs, based on a review framework grounded in the information sharing literature.

The authors’ review revealed that information sharing in African AFSCs is still in its nascent stage. Findings are based on four themes of (1) why share information (mainly to gain market access), (2) what information is shared (price and market information) (3) how it is shared (still traditional communication, with limited adoption of digital technologies?) and (4) antecedents, drivers and barriers (technology adoption and socio-economic background of Africans).

This paper outlines a research agenda for advancing the theory on information sharing in AFSCs. Furthermore, the review highlights the importance of context, supply chain structure, relationships, product characteristics and culture in studying AFSCs.

A review on information sharing in African perishable AFSCs does not appear to exist in operations and supply chain management (O&SCM) and agribusiness journals.

This study aims to more deeply examine the various types of testing mediations and use the comparison test by using test-based mediation Sobel models and Bayesian approach. The purpose of this study are to apply the traditional (using indirect effect) and Sobel test, extend Yuan and MacKinnon (2009) work on Bayesian mediation analysis. Both analysis methods of mediation (Traditional, Sobel Test and Bayesian estimation) should apply in the research of management, by using structural equation modeling (SEM) in a structural model, with one mediation, one exogenous (independent) and one endogenous variable. The meta-analysis approximation has been used to investigate the job satisfaction as a mediation in the relationship between employee competence and performance (endogenous).

Data were collected from ten dissertations of students of the Management Doctoral Program at the Brawijaya University from 2009 until 2013; data were analyzed for the mediation variable of job satisfaction (M) in the relationship between employee competence (X) and employee performance (Y) (Muindi and Obonyo, 2015; Olcer, 2015; Sattar et al., 2015; Khan and Ahmed, 2015). A researcher can determine the mediating variable and whether it is complete or partial or if mediation exists in several ways.

The results of the above findings using meta-analysis showed that 60% of previous research states that job satisfaction is a partial mediation on relationship competence of the performance, 10% of previous research states that job satisfaction is a full mediation on relationship competence of the performance and 30% stated that job satisfaction is not pemediasi (pemediasi means Mediation variable) on the relationship between competence and performance. This research found that all three approaches provide similar conclusions for ten previous research.

The findings showed that the Sobel approach and the Bayesian approach provide results that are more sensitive than the traditional approach.

In my opinion, the rule to investigate the mediation variable should be completed with the conditions (1) q (theta) is not statistically significant, (2) α (alpha) and β (beta) are significant, and (3) q’ (theta) is significant, and increase when M is include as an additional predictor. This condition called partial mediation.

The traditional method is simpler and easy. The method is less sensitive and is not sufficient for investigating the mediating variables. In general, the method results in a mediation variable, but it cannot be used to determine either partial or complete mediation variables. So, investigation by Baron and Kenny Methods (in Hair et al., 2010), the rule or testing called Sobel Test and another approach such as Bayesian to determine the mediation variable is necessary.

Various methods for detecting mediating/intervening have been widely used in previous research as a method of measurement using indirect effect (Hair et al., 2010), and calculations have been performed using Sobel test (Baron and Kenny, 1986) and Bayesian approach (Enders, 2013). In this study, I wanted to more deeply examine the various types of testing mediations, and use the comparison test by using the test-based mediation Sobel models and Bayesian approach (Baron and Kenny, 1986; Enders, 2013). The statistical application should not be complicated and difficult, it but must rather be simple and easy, so that it is user-friendly. The traditional method is simpler and easier than the other methods, but how sensitive is it? This research is conducted to investigate this problem. The evaluation of mediating mechanisms has become a critical element of behavioral science research (Enders, 2013), especially in the field of management, not only to assess whether (and how) interventions achieve their effects but also, more, broadly, to understand the cause of behavioral change. Methodologists have developed mediation analysis techniques for a broad range of substantive applications. However, methods for estimating mediation mechanisms with various methods have been understudied. The purpose of this study is to apply the traditional (using indirect effect) and Sobel tests and extend Yuan and MacKinnon’s (2009) work on the Bayesian mediation analysis. Both analyses methods of mediation (traditional and Sobel test and Bayesian estimation) should apply in the research of management, by using structural equation modeling (SEM) in a structural model, with one mediation, one exogenous (independent) and one endogenous variable. The meta-analysis approximation has been used to investigate job satisfaction as the mediation in the relationship between employee competence and performance (endogenous). This study uses software R to complete the mediating effect (Enders, 2013). R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers et al. R provides a wide variety of statistical analyses such as SEM and Mediation test. R provides an open source route for participation in that activity. The Bayesian estimation approach provides an R function and a macro that applies the method of mediation analysis.
