Framework for productivity and safety enhancement system using BIM in Singapore
Authors: Teo Ai Lin Evelyn , Ofori George , Tjandra Imelda , Kim Hanjoon 
Published: October 2017

Purpose
Despite recognition of its importance to Singapore’s economy, the construction industry is plagued by poor safety and productivity performance. Improvement efforts by the government and industry have yielded little results. The purpose of this paper is to propose a framework for developing a productivity and safety monitoring system using Building Information Modelling (BIM).

Design/methodology/approach
The framework, Intelligent Productivity and Safety System (IPASS), takes advantage of mandatory requirements for building plans to be submitted for approval in Singapore in BIM format. IPASS is based on a study comprising interviews and a questionnaire-based survey. It uses BIM to integrate buildable design, prevention and control of hazards, and safety assessment.

Findings
The authors illustrate a development of IPASS capable of generating productivity and safety scores for construction projects by analysing BIM model information.

Research limitations/implications
The paper demonstrates that BIM can be used to monitor productivity and safety as a project progresses, and help to enhance performance under the two parameters.

Practical implications
IPASS enables collaboration among project stakeholders as they can base their work on analysis of productivity and safety performance before projects start, and as they progress. It is suggested that the BIM model submitted to the authorities should be used for the IPASS application.

Originality/value
IPASS has rule-checking, hazards identification and quality checking capabilities. It is able to identify hazards and risks with the rule-checking capabilities. IPASS enables practitioners to check mistakes and the rationality of a design. It helps to mitigate risks as there are built-in safety measures/controls rules to overcome the problems caused by design deficiency, wrong-material-choice, and more.
Empirical comparison of critical success factors for public-private partnerships in developing and developed countries
Authors: Osei-Kyei Robert , Chan Albert P.C. 
Published: October 2017

Purpose
The purpose of this paper is to investigate the similarities and differences of critical success factors (CSFs) for public-private partnership (PPP) projects in developing and developed countries, using Ghana and Hong Kong as examples.

Design/methodology/approach
An empirical questionnaire survey was conducted with experienced PPP practitioners in Ghana and Hong Kong. Survey responses were analysed using Kendall’s concordance analysis, mean score ranking, quartile groupings analysis and Mann-Whitney U test.

Findings
The results indicate that a favourable legal and regulatory framework is very critical in both jurisdictions. Further, technology transfer, technological innovation, public/community participation and coordination and government providing financial support are of low importance in both jurisdictions. The non-parametric test shows that 16 CSFs are of different importance in Ghana and Hong Kong. Specifically, CSFs related to the socio-political and economic conditions of PPP projects are very critical in Ghana, whereas CSFs directly related to the organisation and relationship of PPP projects are very critical in Hong Kong.

Originality/value
The outputs of this study add to the international best practice framework for successful PPP implementation. Further, international private investors and governments who are yet to adopt the PPP concept would be considerably informed of the investment strategies to employ when engaging in PPP arrangements.
The role of customers and vendors in modern construction equipment technology diffusion
Authors: Sepasgozar Samad M.E. , Loosemore Martin 
Published: October 2017

Purpose
The purpose of this paper is to address the gap in knowledge by exploring the role of customers and vendors in diffusion of modern equipment technologies into the construction industry.

Design/methodology/approach
To address the need to consider both vendors and customers in the innovation diffusion process and the need for in-depth cross-sectional studies, semi-structured interviews were undertaken with 147 participants including 85 vendors and 62 customers of modern construction technologies at company, project and operational levels in Australia and North America. Thematic analysis and an analytic hierarchy process illustrate the critical role of both customers and vendors in the diffusion process of modern equipment technologies.

Findings
A new conceptual model is presented which classifies modern equipment technology customers into four categories: visionaries (group I); innovators (group II); pragmatists (group III); and conservatives (group IV) based on the way in which they interact with vendors in the innovation diffusion process. The results also reveal that there is a significant emotional/affective aspect of innovation diffusion decisions which has not been recognised in previous research.

Originality/value
The major contribution of this study is that it analyses the role of both vendors and customers in the equipment technology diffusion process at three different levels (strategic, project and operational) in large corporations and small-to-medium-sized businesses. The findings not only advance construction innovation research beyond traditional linear models of innovation, but also provide new knowledge which enable customers and vendors to interact more effectively in the diffusion of new construction equipment technologies.
Civil engineers’ personal values/demographics linkage in project team building
Authors: Damci Atilla , Arditi David , Polat Gul 
Published: October 2017

PurposeThe purpose of this paper is to explore the relationship between civil engineers’ demographics (e.g. age, marital status, education, work experience) and their personal values. The objective was to predict civil engineers’ personal values based on their demographics.Design/methodology/approachA questionnaire survey was administered to civil engineers to collect data on their demographics and their personal values. Statistical analysis was performed to verify whether a significant statistical relationship exists between civil engineers’ demographics and their personal values.FindingsThe most important and the least important personal values were identified for civil engineers. Statistical analysis indicated that civil engineers’ values do vary based on their demographics.Research limitations/implicationsThe results of this study cannot be generalized, because individuals’ personal values and demographics are, by definition, local. Location and culture may affect the personal values of civil engineers.Practical implicationsTeam leaders normally have access to information about the demographics of the engineers they employ; based on the results of this study, they should be able to predict their personal values, and to make more informed decisions when appointing them to particular positions on project teams.Originality/valueThe research presented in this paper, establishes for the first time, that a linkage exists between civil engineers’ personal values and their demographics, and makes it easier for team leaders to make assignment decisions.

Authors: Chan Albert P.C. , Wong Francis K.W. , Hon Carol K.H. , Ali Javed Arshad , Lyu Sainan 
Published: October 2017

Purpose
With increasing employment of ethnic minority (EM) workers from different nationalities to mitigate the growing demand for a construction workforce, the safety and health problems of these workers have become a significant concern. The purpose of this paper is to identify and rank according to severity the safety and health-related problems confronted by EM construction workers.

Design/methodology/approach
Grounded theory approach was employed to construct the main categories and subcategories of the construction safety and health problems of EM workers. A two-round Delphi survey of 18 experts, who are highly experienced in managing EM workers, was conducted to rank the relative severity of the identified safety and health problems.

Findings
A total of 14 subcategories and 4 categories of construction safety and health problems of EM workers were identified. Among the 14 subcategories, the most urgent and serious ones were insufficient safety materials and training in their native language, insufficient safety staff from EM origin, and safety communication barriers. In addition, safety and health problems at the corporate and governmental levels are also worth paying attention.

Originality/value
This study contributes to the update on the existing body of knowledge on safety and health problems encountered by EM construction workers and revelation of their peculiar situation in Hong Kong. Findings of the study will be of value to various stakeholders in formulating safety and health measures for EM construction workers.

Authors: Hamzeh Farook , Abdul Ghani Omar , Saleh Bacha Mohammad Bassel , Abbas Yara 
Published: October 2017

Purpose
This study evaluates the enablers and barriers for modular concrete construction in Lebanon. The purpose of this paper is to investigate various factors (time, cost, technical know-how, organizational, sustainability, etc.) and their influence on the choice of the construction method. The paper examines the different assessments of designers, manufacturers, and contractors regarding precast construction in comparison to traditional in-situ methods, and highlights the major differences in their views.

Design/methodology/approach
Structured face-to-face surveys were conducted with top management personnel of precast manufacturers, architectural and engineering firms, and contracting companies in Lebanon. In addition, a case study from the largest precast project in Lebanon was used to provide a deeper understanding of factors encouraging the use of precast concrete, and to highlight major onsite issues associated with its implementation.

Findings
On the one hand, the findings highlight technical, logistical, organizational, and cultural factors that inhibit the use of precast concrete as a construction method. On the other hand, results reveal that cost, time, sustainability, and flexibility factors are the main enablers for increasing the uptake of modular concrete construction.

Originality/value
The main contribution to knowledge is that this study presents different stakeholders’ perspectives on precast concrete construction. Moreover, this is the first research addressing precast concrete construction in the Middle East and Lebanon. The results of the study provide valuable global insights and recommendations that may help increase the uptake of precast concrete construction. They can also guide project stakeholders to properly match project characteristics and precast concrete as a construction method.
Power distance and landlord-tenant practices across countries
Authors: Gholipour Fereidouni Hassan , Tajaddini Reza 
Published: October 2017

PurposeThis paper aims to investigate whether cultural dimension of power distance, which is the extent that inequality is expected and accepted in societies, can explain underlying differences in landlord-tenant practices (LTP) across countries.Design/methodology/approachThe authors use a sample covering countries from different regions. They apply the ordered probit regressions to estimate the relationships between the explanatory variables and LTP.FindingsThe results show that hierarchical societies demonstrate more pro-landlord practices. This finding is robust to alternative measures of power distance and different sample sizes. In addition, the authors find that countries with larger rental sectors and larger numbers of landlords with mortgages demonstrate more pro-tenant practices. The results also show that differences in LTP across countries are not significantly influenced by legal origin.Originality/valueTo the best of the authors’ knowledge, very limited studies have investigated the determinants of LTP across countries. In addition, while cultural values such as power distance have been used to explain the economic, social and financial variables, less, if any, number of studies have used them to explain the variation of real estate market variables such as LTP.
Market heterogeneity, investment risk and portfolio allocation
Authors: Amédée-Manesme Charles-Olivier , Baroni Michel , Barthélémy Fabrice , Des Rosiers François 
Published: October 2017

PurposeThe purpose of this paper is to address the heterogeneity of real estate assets with regard to investment risk measurement, with Paris’ apartment market as a case study.Design/methodology/approachQuantile regression is used to handle the fact that willingness to pay for housing attributes may vary greatly over both space and asset value categories. The method is alternately applied on central and peripheral districts of Paris, or “arrondissements”, with hedonic indices built for nine deciles over a 17-year period (1990-2006). Portfolio allocation is subsequently analysed with deciles being the assets.FindingsThe findings suggest that during the slump, peripheral districts show better resilience and define the efficient frontier while also exhibiting a lower volatility. In addition, higher returns are observed for lower-priced apartments, both central and peripheral. During the recovery and boom stages of the cycle, the highest returns are experienced for the cheapest apartments in central locations, whereas upper-priced, centrally located units yield the lowest returns.Originality/valueThe originality of this research resides in the application of quantile regression in a real estate investment and risk management context. The methodology may raise individual investors’ and practitioners’ attention, especially index providers’.
Robot-enabled execution system for perishables auction logistics
Authors: Kong Xiang T.R. , Zhong Ray Y. , Xu Gangyan , Huang George Q. 
Published: October 2017

Purpose
The purpose of this paper is to propose a concept of cloud auction robot (CAR) and its execution platform for transforming perishable food supply chain management. A new paradigm of goods-to-person auction execution model is proposed based on CARs. This paradigm can shift the management of traditional manual working to automated execution with great space and time saving. A scalable CAR-enabled execution system (CARES) is presented to manage logistics workflows, tasks and behavior of CAR-Agents in handling the real-time events and associated data.

Design/methodology/approach
An Internet of Things enabled auction environment is designed. The robot is used to pick up and deliver the auction products and commends are given to the robot in real-time. CARES architecture is proposed while integrating three core services from auction workflow management, auction task management, to auction execution control. A system prototype was developed to show its execution through physical emulations and experiments.

Findings
The CARES could well schedule the tasks for each robot to minimize their waiting time. The total execution time is reduced by 33 percent on average. Space utilization for each auction studio is improved by about 50 percent per day.

Originality/value
The CAR-enabled execution model and system is simulated and verified in a ubiquitous auction environment so as to upgrade the perishable food supply chain management into a new level which is automated and real-time. The proposed system is flexible to cope with different auction scenarios, such as different auction mechanisms and processes, with high reconfigurability and scalability.
Three-level supply chain coordination of fresh agricultural products in the Internet of Things
Authors: Yan Bo , Wu Xiao-hua , Ye Bing , Zhang Yong-wang 
Published: October 2017

Purpose
The Internet of Things (IoT) is used in the fresh agricultural product (FAP) supply chain, which can be coordinated through a revenue-sharing contract. The purpose of this paper is to make the three-level supply chain coordinate in IoT by considering the influence of FAP on market demand and costs of controlling freshness on the road.

Design/methodology/approach
A three-level FAP supply chain that comprises a manufacturer, distributor, and retailer in IoT is regarded as the research object. This study improves the revenue-sharing contract, determines the optimal solution when the supply chain achieves maximum profit in three types of decision-making situations, and develops the profit distribution model based on the improved revenue-sharing contract to coordinate the supply chain.

Findings
The improved revenue-sharing contract can coordinate the FAP supply chain that comprises a manufacturer, distributor, and retailer in IoT, as well as benefit all enterprises in the supply chain.

Practical implications
Resource utilization rate can be improved after coordinating the entire supply chain. Moreover, loss in the circulation process is reduced, and the circulation efficiency of FAPs is improved because of the application of IoT. The validity of the model is verified through a case analysis.

Originality/value
This study is different from other research in terms of the combination of supply chain coordination, FAPs, and radio frequency identification application in IoT.
Representation of indigenous cultures: considering the Hawaiian hula
Authors: Hajibayova Lala , Buente Wayne 
Published: October 2017

PurposeThe purpose of this paper is to explore the representation of Kanaka Maoli (Hawaiian) Hula Dance in traditional systems of representation and organization.Design/methodology/approachThis exploratory study analyzes the controlled and natural language vocabularies employed for the representation and organization of Hawaiian culture, in particular Hawaiian hula. The most widely accepted and used systems were examined: classification systems (Library of Congress Classification and Dewey Decimal Classification), subject heading systems (Library of Congress Subject Headings and authority files (Library of Congress and OCLC Authority Files), and citation indexing systems (Web of Science Social Sciences and Art and Humanities databases).FindingsAnalysis of various tools of representation and organization revealed biases and diasporization in depictions of Hawaiian culture. The study emphasizes the need to acknowledge the aesthetic perspective of indigenous people in their organization and presentation of their own cultural knowledge and advocates a decolonizing methodology to promote alternative information structures in indigenous communities.Originality/valueThis study contributes to the relatively limited scholarship on representation and organization for indigenous knowledge organization systems, in particular Hawaiian culture. Research suggests that access to Native Hawaiian cultural heritage will raise awareness among information professionals in Hawai’i to the beauty of Native Hawaiian epistemology.
Heuristics elements of information-seeking strategies and tactics: a conceptual analysis
Authors: Savolainen Reijo 
Published: October 2017

PurposeThe purpose of this paper is to elaborate the picture of strategies and tactics for information seeking and searching by focusing on the heuristic elements of such strategies and tactics.Design/methodology/approachA conceptual analysis of a sample of 31 pertinent investigations was conducted to find out how researchers have approached heuristics in the above context since the 1970s. To achieve this, the study draws on the ideas produced within the research programmes on Heuristics and Biases, and Fast and Frugal Heuristics.FindingsResearchers have approached the heuristic elements in three major ways. First, these elements are defined as general level constituents of browsing strategies in particular. Second, heuristics are approached as search tips. Third, there are examples of conceptualizations of individual heuristics. Familiarity heuristic suggests that people tend to prefer sources that have worked well in similar situations in the past. Recognition heuristic draws on an all-or-none distinction of the information objects, based on cues such as information scent. Finally, representativeness heuristic is based on recalling similar instances of events or objects and judging their typicality in terms of genres, for example.Research limitations/implicationsAs the study focuses on three heuristics only, the findings cannot be generalized to describe the use of all heuristic elements of strategies and tactics for information seeking and searching.Originality/valueThe study pioneers by providing an in-depth analysis of the ways in which the heuristic elements are conceptualized in the context of information seeking and searching. The findings contribute to the elaboration of the conceptual issues of information behavior research.
Service innovations breaking institutionalized rules of health care
Authors: Wallin Arto Juhani , Fuglsang Lars 
Published: October 2017

PurposeAlthough the digital era has given rise to major transformations in many industries, health care has been remarkably resistant to radical innovations coming outside the field. The purpose of this paper is to explore and explain how new ventures aim to break institutional arrangements (i.e. regulations, normative rules, and cultural-cognitive beliefs) protecting the field by introducing digitally enabled service innovations into health care markets.Design/methodology/approachThe study is qualitative and interpretative in nature and utilizes case study as a research strategy. The paper is based on data that were collected through narrative interviews and document analysis from seven new ventures participating in a start-up accelerator program.FindingsResults indicate that service innovations that require a change in the institutional structures of the health care system are enacted through three highly iterative key processes: institutional sensemaking that creates an understanding of prevailing institutional arrangements and that constructs meaning for institutional change efforts, theorization of change through linguistic device, and modifications of institutions by building legitimacy and mobilizing external constituencies.Practical implicationsThe findings provide practical insights into how new ventures struggle, navigate, and negotiate on specific alternatives related to institutional change while pursuing the introduction of innovations to market.Originality/valueThis research extends the institutional perspective on service innovation by zooming into micro-level processes of institutional change driven by new ventures. The study develops the theory of institutional entrepreneurship by highlighting cognitive processes of change, and suggests incorporating “institutional thinking” more tightly into the study and management of service innovation.
