Risk of excavators overturning
Authors: Edwards David , Parn Erika A. , Sing Michael C.P. , Thwala Wellington Didibhuku 
Published: February 2019

PurposeTracked hydraulic excavators are versatile and ubiquitous items of off-highway plant and machinery that are utilised throughout the construction industry. Each year, a significant number of excavators overturn whilst conducting a lifting operation, causing damage to property, personnel injury or even fatality. The reasons for the overturn are myriad, including: operational or environmental conditions; machine operator acts or omissions; and/or inadequate site supervision. Furthermore, the safe working load (SWL) figure obtained from manufacturer guidance and utilised in lift plans is based upon undertaking a static load only. The purpose of this paper is to determine whether the SWL is still safe to be used in a lift plan when slewing a freely suspended (dynamic) load, and, if not, whether this may be a further contributory factor to overturn incidents.Design/methodology/approachPrevious research has developed a number of machine stability test regimes but these were largely subjective, impractical to replicate and failed to accurately measure the “dynamic” horizontal centrifugal force resulting from slewing the load. This research contributes towards resolving the stability problem by critically evaluating existing governing standards and legislation, investigating case studies of excavator overturn and simulating the dynamic effects of an excavator when slewing a freely suspended load at high rotations per minute (rpm). To achieve this, both the static load and horizontal centrifugal force from slewing this load were calculated for six randomly selected cases of an excavator, with different arm geometry configurations.FindingsThe results from the six cases are presented and a worked example of one is detailed to demonstrate how the results were derived. The findings reveal that the SWL quoted on an excavator’s lift rating chart considerably underestimates the extra forces experienced by the machine when an additional dynamic load is added to the static load whilst lifting and slewing a freely suspended load.Originality/valueThis work presents the first attempt to accurately model excavator stability by taking consideration of the dynamic forces caused by slewing a freely suspended load and will lead to changes in the way that industry develops and manages lift plans. Future research proposes to vary the weight of load, arm geometry and rpm to predict machine stability characteristics under various operational conditions, and exploit these modelling data to populate pre-programmed sensor-based technology to monitor stability in real time and automatically restrict lift mode operations.
A hybrid approach to optimize initial design strategies for pre-sale housing projects
Authors: Juan Yi-Kai , Lin I-Chieh , Tsai Ji-Xuan 
Published: February 2019

Purpose
The purpose of this paper is to propose a hybrid decision-making model for optimizing the initial design strategies of pre-sales housing, identifying factors affecting the initial design of housing, and developing different initial design approaches and strategies based on buyers’ preferences.

Design/methodology/approach
Indicators and factors in line with the local initial planning and design are created according to the design quality indicator framework. The important indicators and factors are screened out preliminarily with the fuzzy Delphi method and decision-making trial and evaluation laboratory based analytic network process. The performances of two actual cases under similar site conditions are checked with regard to the overall residential sales rate and time on the market (TOM).

Findings
The result shows that the proposed model can effectively improve the sales rate, shorten the TOM and better complies with buyer design strategy demands, and thus positively correlating to economic value.

Originality/value
Pre-sales make possible the customized strategy of allowing future residents to participate in the housing design process. However, buyers’ participation in the design process is highly limited, and developers usually determine their planning and initial residential design strategies based on experience and intuition. With the proposed approach, the initial residential design of a project can be effectively intervened, so that home users can truly participate in the design, and the residential construction service can be provided in a unique, but non-universal way.
Exploring the interactions among factors impeding the diffusion of prefabricated building technologies
Authors: Gan Xiao-Long , Chang Rui-Dong , Langston Craig , Wen Tao 
Published: February 2019

Purpose
The purpose of this paper is to identify the interactions of factors impacting the widespread adoption of prefabricated building technologies and the intervention strategies to facilitate the development of prefabrication based on fuzzy cognitive maps (FCMs).

Design/methodology/approach
Through in-depth interviews with six stakeholder groups, namely, the government, developers, designers, contractors, manufacturers and researchers, 13 critical factors were identified and used to construct stakeholder-grouped FCMs, which were further aggregated into a collective FCM. The complexity and density of the collective FCM and the centrality of factors in the FCM were examined. Subsequently, a series of “what-if” simulations of the collective FCM were conducted to analyze the effectiveness of different interventions in promoting prefabrication.

Findings
The results show that three factors including market demand, cost, and policies and regulations have been mentioned by all stakeholder groups. However, these factors were ranked differently by stakeholder groups, implying that different stakeholder groups perceive the barriers to prefabricated building technologies differently. FCM simulations show that strengthening policies and regulations yield the strongest overall effect stimulating prefabrication, alleviating the organizational and environmental barriers more than the technological barriers, while improving the knowledge and expertise alleviate the technological barriers more. These measures need to be accompanied by other approaches, such as reducing cost and improving quality.

Research limitations/implications
It is a tough task to promote prefabrication as it is affected by numerous barriers with complex interactions, which have been overlooked by previous studies. This study clearly shows which strategy could tackle which barriers to prefabrication through the FCM simulations. This provides valuable references for the enterprises’ decision making and the governments’ policy making to facilitate the diffusion of prefabricated building technologies.

Originality/value
Few studies aim to analyze the interactions among the barriers to prefabrication, while this study specifically investigates this issue by illustrating the complex interactions using FCMs. Few studies also aim to identify the intervention strategies promoting prefabrication based on a quantitative approach, while this study employs FCM simulations to directly simulate the effectiveness of different strategies to facilitate prefabrication in a quantitative manner.
Effects of team diversity on project performance in construction projects
Authors: Wu Guangdong , Zhao Xianbo , Zuo Jian , Zillante George 
Published: February 2019

PurposeThe purpose of this paper is fourfold: first, to investigate the effect of team diversity on different types of conflicts; second, to determine if team diversity is significantly correlated with project performance; third, to investigate the mediating effect of project conflicts on the relationship between team diversity and project performance and fourth, to examine the relationship between different types of conflicts and project performance in construction projects.Design/methodology/approachA theoretical model was developed and a questionnaire survey was conducted with 246 professionals. The structural equation modeling technique was applied to analyze the data.FindingsThe results showed that: team diversity was positively associated with project performance; the introduction of conflicts significantly weakened the effect of diversity on performance; conflicts have both constructive and destructive effects on project performance; and team diversity affected project performance through the mediating effects of task conflict and relationship conflict, thus adding both positive and negative effects on performance.Research limitations/implicationsThere are other factors which may affect conflicts and project performance such as communication, trust and contract. Future research could be conducted to determine the role of these variables in determining the effects of team diversity on performance.Practical implicationsIt is necessary to reduce the relationship conflict whereas maintaining a “healthy” level of task conflict. In light of this, the conclusions of this study highlight practical implications as follows: project teams should attach importance to diverse partner selection and select cooperative partners whose value orientations are similar; when implementing a construction project, the structure of diverse project teams should keep relatively stable, avoiding too many teams entering or exiting the project in a short period; project teams should make greater efforts to deal with destructive conflicts via relational governance such as trust and communication.Originality/valueThis study contributes to the literature in three areas. First, this study investigated the dynamic mechanism between team diversity, conflicts and performance in construction projects. Second, this study contributes to the body of knowledge on validating the mediating effects of conflicts on the relationship between team diversity and performance. Third, this study validated the positive and negative effects of team diversity on performance with different types of conflicts as mediation variables in construction projects.

Authors: Ekanayake E.M.A.C. , Shen Geoffrey , Kumaraswamy Mohan M. 
Published: February 2019

PurposeThe purpose of this paper is to review the state-of-the-art of literature of value management (VM) and to map the VM domain to provide a launch pad for further knowledge development and dissemination.Design/methodology/approachThis study employed CiteSpace bibliometric analysis software to systematically, comprehensively and accurately review the VM-related literature and to map the VM knowledge domain.FindingsThe results reveal the current VM knowledge base, clusters, research hotspot, and the evolutionary trajectory while contributing to the development of VM knowledge by providing a dynamic platform for integrating future developments in research.Originality/valueThe contribution of this paper to scientific VM knowledge is, therefore, a quantitative and accurate VM knowledge map based on a bibliometric analysis of data from the VM knowledge base, domains and evolution. The findings can be generalised and used as an effective knowledge mapping tool in a specific field of study that could complement and add significant value to the often adopted more traditional literature reviews. This study further recommends that the proposed knowledge map be frequently updated by similar future studies to fill gaps that arise with changing needs, priorities and contexts, as well as to identify corresponding future demands in the VM research domain.
Integrative capability, business model innovation and performance
Authors: Pang Changwei , Wang Qiong , Li Yuan , Duan Guang 
Published: February 2019

PurposeThe purpose of this paper is to examine how business model innovation (BMI) mediates the relationship between integrative capability, business strategy and firm performance.Design/methodology/approachA literature review provides the model and hypotheses. Using a sample of 165 Chinese firms, the authors conduct the examination using a theoretical model and hypotheses following standard analysis methods.FindingsThe results show that BMI positively mediates the relationship between integrative capability and firm performance. Moreover, a differentiation strategy positively moderates the link between BMI and firm performance, while a cost leadership strategy presents a significantly negative moderating effect.Research limitations/implicationsFirst, the authors test the hypotheses using data from China; thus data from other emerging economies should be tested. Second, the authors use cross-sectional data in this study making it impossible to verify the dynamic developed in the process of BMI; a longitudinal study could provide a more comprehensive understanding. Third, the authors consider one intermediate mechanism to test the relationship of integrative capability and firm performance; additional factors may link integrative capability and firm performance.Practical implicationsThe mediating effect of BMI suggests managers should pay more attention to BMI to improve firm performance, and they should understand that BMI’s role varies across different business strategies.Originality/valueThe paper is original in its investigation of the effect of integrative capability and BMI on firm performance using data from China and demonstrates the mediating effect of BMI on the relationship between integrative capability and firm performance.
Online insurance claims: when more than trust matters
Authors: Gebert-Persson Sabine , Gidhagen Mikael , Sallis James E. , Lundberg Heléne 
Published: February 2019

PurposeThe purpose of this paper is to develop and test a theoretical framework explaining the adoption of online insurance claims characterised by infrequent interactions, inherent complexity and risk. It extends the technology acceptance model to include knowledge-related and trust-related beliefs.Design/methodology/approachThe framework is tested with structural equation modelling using data from a survey of 292 customers who made online insurance claims. Findings are further explained through 30 telephone interviews conducted with online and offline claimants.FindingsPrevious research in financial services has shown trust to be equally or more important than perceived usefulness and perceived ease of use in forming attitudes towards adopting online insurance applications. The findings of this paper contradict this by showing, at best, a weak relationship between trusting attitude and intention to use the online service. Trust is somewhat meaningful; however, perceived ease of use, perceived usefulness and technology attitude are substantially more important in an online insurance claims setting.Research limitations/implicationsContradictory results always beg further research to assure their robustness. Nevertheless, they can also point to a developing trend where trust in the internet channel,per se, is of diminishing importance. Internet and product knowledge are not as pertinent to forming intentions as usefulness and ease of use.Practical implicationsTo encourage customers to adopt online applications for a trusted company, all emphasis should be on user friendliness and perceived usefulness of the online interface.Originality/valueCompared to other channels, consumers are no longer naïve or distrustful of the online channel for interacting with a firm. If they perceive usefulness and ease of use, they will adopt the offered service.
Presentational format and financial consumers’ behaviour: an eye-tracking study
Authors: Ceravolo Maria Gabriella , Farina Vincenzo , Fattobene Lucrezia , Leonelli Lucia , Raggetti GianMario 
Published: February 2019

Purpose
The purpose of this paper is to examine whether financial consumers are sensitive to presentational format of financial disclosure documents and whether this influences the financial attractiveness of products.

Design/methodology/approach
In order to observe and measure consumers’ attention, the authors exploit the unobtrusive methodology of eye tracking on a sample of nonprofessional investors, applying an ecological protocol, through a cross-sectional design.

Findings
The analysis reveals that financial information processing and attention distribution are influenced by the way the information is conveyed. Moreover, some layouts induce individuals to rate the products as less financially attractive, independent of the information content. This suggests the importance of studying the neural mechanisms of investors’ behaviour in the scrutiny of financial product documents.

Practical implications
The results lead to recommend regulators and managers to study how investors respond to financial disclosure documents by exploiting neuroscientific techniques. Moreover, there is a role for the search of any benefit coming from emphasising specific sources of information inside documents.

Originality/value
This research investigates the influence of presentational format on consumers’ information processing measuring the underlying neurophysiological processes; the consequent perception of financial attractiveness is also explored.
Can gamification improve financial behavior? The moderating role of app expertise
Authors: Bayuk Julia , Altobello Suzanne Aurora 
Published: February 2019

Purpose
The purpose of this paper is to explore potential benefits of gamification (application of game-playing elements) for financial well-being and motivation to save.

Design/methodology/approach
A preliminary survey of college students explored how gamification principles incorporated into money-savings/personal finance smartphone apps could improve financial well-being. The main study utilized Mechanical Turk participants, exposing them to financial game app descriptions that emphasized social features (e.g. leaderboards and ability to share achievements) or economic features (e.g. ability to earn real money or a higher interest rate). Objective and subjective financial measures including expertise with financial apps, perceived benefits of financial apps and behavioral intentions were examined.

Findings
Financial worry, financial literacy, subjective knowledge and expertise with money-savings/financial applications predicted financial well-being. Additionally, consumers varied in their preferences for certain financial game app features based on past financial app experience. Those who already used a financial app tend to exhibit higher subjective (though not objective) knowledge, and want both “social” and “economic” features of financial applications, whereas those with no experience are more motivated by economic features.

Practical implications
These results could be used to guide game designers regarding which features may be more attractive to consumers depending on their prior expertise with financial smartphone applications. Financial services marketing would benefit from further research into whether smartphone financial applications that emphasize social features have benefits for consumers’ motivation and financial well-being.

Originality/value
Examining college students about to enter the real world and the general population, this project contributes to research to improve understanding of financial well-being by examining how already having a financial gamification application impacts perceptions of knowledge and expertise, as well as intentions to save given a more socially focused vs economically focused savings app. Additional research needs to further explore gamification as an experimental intervention to ultimately improve both subjective financial well-being and objective financial behaviors, especially for consumers with lower expertise and high risk of financial vulnerability.
Referral reward programs with scarcity messages on bank credit card adoption
Authors: Song Chanho , Wang Tuo , Hu Michael Y. 
Published: February 2019

PurposeThe purpose of this paper is to investigate how referral reward programs (RRPs) with scarcity messages influence consumer’ recommendation behavioral intentions about a bank credit card.Design/methodology/approachIn total, 1,599 consumers are accessed through Amazon’s Mechanical Turk worker panel. The authors use general linear models, analysis of variance and analysis of covariance to test the proposed hypotheses.FindingsThe results showed that offering RRPs with scarcity messages increases a consumer’s behavioral intentions to recommend. The limited-quantity message in RRPs has the highest positive impact on consumers’ behavioral intentions.Originality/valueNo prior studies have addressed the relationship between referral rewards and scarcity messages in the bank credit card context. The study contributes to the understanding of the effectiveness of RRPs with scarcity message in improving consumer’s referral.
Teachers’ goals predict computational thinking gains in robotics
Authors: Witherspoon Eben B. , Schunn Christian D. 
Published: February 2019

Purpose
Computational thinking (CT) is widely considered to be an important component of teaching generalizable computer science skills to all students in a range of learning environments, including robotics. However, despite advances in the design of robotics curricula that can teach CT, actual enactment in classrooms may often fail to reach this target. This study aims to understand whether the various instructional goals teachers’ hold when using these curricula may offer one potential explanation for disparities in outcomes.

Design/methodology/approach
In this study, the authors examine results from N = 206 middle-school students’ pre- and post-tests of CT, attitudinal surveys and surveys of their teacher’s instructional goals to determine if student attitudes and learning gains in CT are related to the instructional goals their teachers endorsed while implementing a shared robotics programming curriculum.

Findings
The findings provide evidence that despite using the same curriculum, students showed differential learning gains on the CT assessment when in classrooms with teachers who rated CT as a more important instructional goal; these effects were particularly strong for women. Students in classroom with teachers who rated CT more highly also showed greater maintenance of positive attitudes toward programming.

Originality/value
While there is a growing body of literature regarding curricular interventions that provide CT learning opportunities, this study provides a critical insight into the role that teachers may play as a potential support or barrier to the success of these curricula. Implications for the design of professional development and teacher educative materials that attend to teachers’ instructional goals are discussed.
