Abstract

Purpose

Compared with traditional approaches, integrated project delivery (IPD) improves project performance by enhancing integration. To adopt IPD, however, existing practices need to be changed, which creates barriers to implementation. This study aims to identify the barriers to IPD practices in China and Singapore, whose practitioners show different types and levels of integration experience.

Design/methodology/approach

A questionnaire survey was administered to two groups of respondents: Chinese and Singaporean. The data were analyzed using three nonparametric techniques, including Wilcoxon signed-rank test, Mann-Whitney-Wilcoxon test, and Spearman rank correlation.

Findings

(1) Of 39 possible barriers, 36 were consistently felt by both Chinese and Singaporean practitioners with different backgrounds; (2) The Chinese group perceived more issues to be significant barriers than the Singaporean group; (3) The Singaporean group had more experience than the Chinese group in performing integration in five areas. This lessens some barriers to adopting IPD practices.

Originality/value

This study is important because it uncovers barriers to the effective implementation of IPD and shows the importance of certain types and levels of integration experience in overcoming these barriers. The results will be useful to practitioners planning to adopt IPD in China or Singapore.

Abstract

Purpose

In an integrated circuit (IC) substrate, more fillers, including talcum powder and aluminium hydroxide, are added, which leads to much higher rigidity and hardness compared with a traditional printed circuit board. However, the micro drilling of IC substrates is harder. This paper aims to test the drilling process of IC substrates to improve the drilling process and the micro hole quality.

Design/methodology/approach

Substrate drilling by a micro drill with 0.11-mm diameter was used under several drilling conditions. The influence of drilling conditions on the drilling process was observed. Drilling forces, drill wear and micro hole quality were also studied.

Findings

The deformation circle around holes, hole location accuracy, bugle hole and burrs were the major defects of micro holes that were observed during the drilling of the substrate. Reducing the drilling force and drill wear was the effective way to improve hole quality.

Originality/value

The technology and manufacturing of IC substrates has been little investigated. Research data on drilling IC substrates is lacking. The micro hole quality directly affects the reliability of IC substrates. Thus, improving the drilling technology of IC substrates is very important.

Abstract

Purpose

Integrated project delivery (IPD) project that does not use multiparty agreement is identified as IPD-ish. The use of IPD-ish arrangement by incorporating integration practices in conventional contract can be viewed as the part of the adoption process of IPD. Moreover, inappropriate integration practices invite new forms of risks and the absence of multiparty agreement adds to the challenges of risk management in IPD-ish projects. This study discusses such challenges and proposes the use of joint risk management to address the potential pitfalls in IPD-ish arrangement.

Design/methodology/approach

A mixed research method was applied. First, the criticality of IPD-ish general and integration-specific risks was examined through a survey. Second, a real IPD-ish project was used to exemplify the use of joint risk management (JRM) to manage IPD-ish risks.

Findings

Two types of risks, namely integration risks (IRs) and general risks (GRs), are identified in IPD-ish projects. Two major findings for the IRs: (1) the most critical IRs are related to unbalanced incentivization and inefficient multidisciplinary teams; and (2) only team formation related pre-contract JRM strategies affect IRs. As for the GRs, the most critical ones are associated with design issues and can be effectively mitigated by post-contract JRM.

Originality/value

Using IPD-ish arrangement is an inevitable part of implementation of full IPD. This happens as many change-averse owners would like to test the integration principles using a conventional contract that they are familiar with. In fact, success in IPD-ish would pave the path for further adoption of IPD. This study offers insight into categorization of risks in IPD-ish projects. Appropriate use of post-contract and organization related pre-contract JRM would improve the chance of teasing out the values of IPD through IPD-ish arrangements. Care should be taken to introduce some contracting integration initiatives, such as risk/reward sharing incentive.

Abstract

Purpose

This paper aimed to examine the role of knowledge sharing among member enterprises between collaborative innovation activities and innovation performance and between building information modeling (BIM) application and innovation performance in the construction supply chain.

Design/methodology/approach

The structural equation model was used in this study. First, the hypothesis of the relationship between collaborative innovation activities, BIM application, knowledge sharing and innovation performance in the construction supply chain was proposed based on experience; then, the research data were collected by investigation; finally, this hypothesis was tested through data analysis.

Findings

(1) Collaborative innovation activities in the construction supply chain had a positive impact on explicit knowledge sharing, tacit knowledge sharing and innovation performance. (2) BIM application had a positive impact on explicit knowledge sharing and innovation performance, while it had no significant impact on tacit knowledge sharing. (3) Explicit knowledge sharing had no positive effect on innovation performance, while tacit knowledge sharing had positive effect on organizational performance. (4) Tacit knowledge sharing produced partial mediating effect between collaborative innovation activities, BIM application and innovation performance, while explicit knowledge sharing produced complete mediating effect between BIM application and tacit knowledge sharing.

Originality/value

A relationship model among collaborative innovation activities, BIM application, explicit and tacit knowledge sharing and innovation performance in the construction supply chain was proposed, and the rationality of the model was verified by empirical analysis. Discovering the relationships between these factors can be not only conducive to mastering the effect of explicit and tacit knowledge sharing in the collaborative innovation process of construction supply chain, but also play a guiding role for the function development of BIM.

Abstract

Purpose

The main purpose of this study is to examine the damage behavior of flexural members under different loading conditions. The finite element model is proposed for the prediction of modal parameters, damage assessment and damage detection of flexural members. Moreover, the analysis of flexural members has been done for the sensor arrangement to accurately predict the damage parameters without the laborious work of experimentation in the laboratory.

Design/methodology/approach

Beam-like structures are structures that are subjected to flexural loadings that are involved in almost every type of civil engineering construction like buildings, bridges, etc. Experimental Modal Analysis (EMA) is a popular technique to detect damages in structures without requiring tough and complex methods. Experimental work conducted in this study concludes that a structure experiences high changes in modal properties once when cracking occurs and then at the stage where cracks start at the critical neutral axis. Moreover, among the various modal parameters of the flexural members, natural frequency and mode shapes are the viable parameters for the damage detection.

Findings

For torsional mode, drop in natural frequency is high for higher damages as compared to low levels. This is because of the opening and closing of cracks in modal testing. When damage occurs in the structure, there is a reduction in the magnitude of the FRF plot. The measure of this drop can also lead to damage assessment in addition to damage detection. The natural frequency of the system is the most reliable modal parameter in detecting damages. However, for damage localization, the next step after damage assessment, mode shapes can be more helpful as compared to all other parameters.

Originality/value

Effect on Dynamic Properties of Flexural Members during the Progressive Deterioration of Reinforced Concrete Structures is studied.

Abstract

Purpose

The purpose of this paper is to review available technologies, analyse their features, propose a new approach of 3D sand mould printing based on line forming, introduce the manufacturing principle and show advantages of this approach, especially for larger parts with large Z steps in the build, such as 2 mm stepwise.

Design/methodology/approach

This paper introduces 3D sand mould printing, compares and analyses technological process and existing fabrication approaches among available technologies first. Then, a new approach of 3D sand mould printing is proposed to improve build speed. In addition, the proposed system will be analysed or benchmarked against existing systems.

Findings

A new approach based on line forming of sand mould printing is put forward by reviewing and analysing available technologies, to improve build speed from the aspect of basic moulding movement instead of optimization of moulding methods and process parameters. The theoretical calculation and analysis shows that build speed can be improved greatly, and it is more suitable for the manufacture of large-scale casting’s sand mould when considering dimensional accuracy and printing error, as well as uniformity of each layer.

Research limitations/implications

The specific implement scheme of line forming and nozzle’s specific structure of this new approach need further study.

Practical implications

Much higher build speed of 3D sand mould printing with new approach brings evident implication for moulds companies and manufacturing industry, having a far-reaching influence on the development of national economy.

Originality/value

This paper reviews available technologies and presents a new approach of 3D sand mould printing for the first time. Analysis of the new approach shows that this new method of sand mould printing can boost build speed greatly. So, its application prospect is great.

Abstract

Purpose

The purpose of this paper is to explore the consumer acceptance of a functional meat processed product made with different meat sources, and to distinguish the existence of different market segments.

Design/methodology/approach

Non-probability sampling was used to recruit a sample of 411 consumers in Southern Chile, over the age of 18 and responsible for the purchase of meat products for their household.

Findings

Using a fractional factorial design for conjoint analysis, it was found in the total sample that the meat source of the meat processed product was more important than packaging, region of origin, price and the functional ingredient claim, with preference for lamb and pork meat processed products with omega-3. Two main segments were identified using a cluster analysis; these segments differed according to family size, presence and age of children, ethnic origin, general health interest, quality of diet and level of satisfaction with food-related life. The largest segment (56.0 percent) shows a high preference toward lamb meat processed product with dietary fiber and omega-3. The second (33.6 percent) preferred turkey meat processed product with antioxidants.

Practical implications

A differentiated marketing strategy with different meat sources and functional ingredients may give access to a large market share. People more willing to accept different functional ingredients in processed meat products may enjoy a better quality of life. The level of satisfaction with food-related life and quality of diet can be useful in explaining preferences for functional meat processed products.

Originality/value

This is the first study to evaluate consumer acceptance of a functional meat processed product made with three different meats and three different functional ingredient claims, which analyzed the relationship between acceptance, the consumer’s quality of diet and their level of satisfaction with food-related life.

Abstract

Purpose

Drawing on the stakeholder theory and stimulus-organism-response (S-O-R) model, this study examines the relationship between corporate social responsibility (CSR) disclosures and users' knowledge-sharing behaviors on social media (SM). Two underlying mechanisms are used to explain the relationship between CSR disclosures and knowledge sharing, namely, CSR identification and content richness.

Design/methodology/approach

An empirical analysis based on a negative binomial regression model is conducted using CSR data disclosed on corporate official Microblog in the past year on 30 companies with a high CSR development index in China.

Findings

CSR disclosures are positively related to users' knowledge-sharing behaviors, and this relationship is mediated by CSR identification. Content richness strengthens the positive relationship between CSR disclosures and users' CSR identification. User's retweeting behavior is positively related to commenting behavior.

Originality/value

This is one of the few studies to investigate the relationship between CSR disclosures and knowledge sharing on SM. The findings of this study can help companies formulate and implement effective CSR disclosure strategies to achieve sustainable development of companies.

Abstract

Purpose

The purpose of this paper is to conduct a large-sample empirical investigation of how relational capital impacts bullwhip at the supplier.

Design/methodology/approach

The study uses mandatory disclosures in regulatory filings of US firms to identify a supplier’s major customers and constructs empirical proxies of supply chain relational capital, i.e., length of the relationship between suppliers and customers and partner interdependence. Multivariate regression analyses are performed to examine the effects of relational capital on bullwhip at the supplier.

Findings

The findings show that bullwhip at the supplier is greater when customers are more dependent on their suppliers, but is reduced when suppliers share longer relationships with their customers. The results also provide additional insights on several firm characteristics that impact supplier bullwhip, including shocks in order backlog, selling intensity and variations in profit margins. Furthermore, the authors document that the effect of supply chain relationships on bullwhip tends to vary across industries and over time.

Originality/value

The study employs a novel data set that is constructed using firms’ financial disclosures. This large panel data set consisting of 13,993 observations over 36 years enables thorough and robust analyses to characterize supply chain relationships and gain a deeper understanding of their impact on bullwhip.
