Abstract

Purpose

The purpose of this paper is to develop a dress design knowledge base (DDKB), which is expected to be further applied to a personalized dress recommendation system.

Design/methodology/approach

Dress design knowledge can be expressed as the relationship between designer's fashion perceptions of different dress elements. In order to extract dress design knowledge, a dress shape ontology (DSO) is firstly developed, which can be further used to form a dress element matrix (DEM). A perceptual descriptive space of the dress (DPDS) is developed for the description of the designer's fashion perception of dress. Through a standard sensory evaluation procedure performed by experienced experts (designers), the expected relationship can be obtained. This relationship is then mathematically simulated by fuzzy logic tools for the expected DDKB.

Findings

In this paper, a DDKB has been developed. The established knowledge base has been validated, and it can be further applied to dress recommendation system for a specific consumer.

Originality/value

This study introduces the concept of knowledge base to the area of dress individualized design. The knowledge-based design process based on sensory evaluation and fuzzy logic can efficiently solve the individualization of dress design in traditional design processes, which can provide a novel way to dress design individualization.

Abstract

Purpose

Previous studies have proposed that correctly managing stakeholders with certain attributes can benefit project management; however, robust theoretical elaborations and empirical investigations of this topic have been lacking. The purpose of this study is to empirically test the effects of two stakeholder attributes – contractor-perceived contractor salience and contractor project position – on the criticality of five typical contractor-related risks: risk of (1) injuries and accidents, (2) quality defects, (3) work delays, (4) cost overruns and (5) breaches of contract.

Design/methodology/approach

Questionnaire data were collected from 118 Chinese contractor managers. Regression models were run in Mplus 7.11 to test the hypotheses.

Findings

The data show that higher contractor-perceived contractor salience and a more supportive contractor project position were both related to lower criticality of contractor-related risks, including risk of (1) injuries and accidents, (2) quality defects, (3) work delays, (4) cost overruns and (5) breaches of contract. Contractor salience also mediated the negative relationship between a supportive contractor project position and the criticality of contractor-related risks.

Research limitations/implications

The authors’ research design is cross-sectional and thus cannot establish causation in the relationships among the studied variables. The single item measure of contractor project position was used for the first time in the present study; thus, its reliability and validity still await more empirical examinations.

Originality/value

The findings advance the understanding of the value of stakeholder management in projects by specifying that prioritizing stakeholders' claims and securing their support for the project reduce the criticality of stakeholder-related risks. By providing empirical evidence from the construction context, the findings also add to knowledge on the instrumental power of stakeholder management in enhancing project risk management performance.

Abstract

Purpose

This paper aims to unveil the importance of knowledge management on a firm’s strategic emergency response during the great negative shock from global public health threats. Through analyzing how representative firms in China’s new economy industries dealt with the COVID-19 pandemic before, during and after the crisis, the significant problems confronted by these firms are pointed out, and the important role knowledge management capabilities played in solving these problems is proven.

Design/methodology/approach

The open data of listed companies regarding the important role knowledge management played in firms’ strategic emergency response during the COVID-19 pandemic are qualitatively analyzed. Based on theoretical sampling, this paper selects representative samples of enterprises and analyzes the positive response measures they took after being hit by this public health event to gain qualitative insight into the importance of knowledge management capabilities in strategic emergency response.

Findings

Three aspects of the important role of knowledge management capabilities in a firm’s strategic emergency response during the COVID-19 pandemic are introduced: before the crisis, firms should strengthen the acquisition, sharing and integration of knowledge so that they can intensify their monitoring for uncertain risks; during the crisis, firms should boost the transmission, transformation and diffusion of knowledge to improve emergency cooperation; and after the crisis, companies should reinforce knowledge evaluation, creation and application to enhance “immunity” in similar emergencies.

Research limitations/implications

This paper has important implications for bolstering strategic emergency management practice and knowledge management capability among firms. Future research must focus on the following two aspects for further investigation: the dynamic relationship between firm knowledge management capability and strategic emergency response ability; and the collaboration system between firm knowledge management and strategic emergency response behaviors.

Originality/value

This paper discusses the important role knowledge management capabilities play in firms’ strategic emergency responses based on insights gained from the significant changes that the COVID-19 pandemic caused to representative Chinese new economy firms. By analyzing the three stages of before, during and after the emergency, this paper proposes the exact efforts that new economy companies should make in improving knowledge management capability.

Abstract

Purpose

The large scale of construction projects and the coexistence of multiple logics in the construction field are sparking interest in applying an institutional perspective to investigate managerial issues in construction projects. However, only a few conceptual papers have been published thus far, and a literature review is needed to identify how that knowledge domain has developed. Based on the results of bibliometric analysis and content analysis, this study proposes potential future avenues for institutional theory in construction project management (ITCPM) studies.

Design/methodology/approach

This paper reports a bibliographic coupling analysis and a co-citation analysis conducted to identify existing research trajectories and determine the primary features of the current ITCPM literature. In addition, this paper employed a content analysis, identified the evolutionary stages of ITCPM knowledge over time and built a framework of existing research.

Findings

This paper first identified that the existing ITCPM studies evolve through three stages, and that the intellectual core of ITCPM studies can be categorized into five clusters. In addition, this paper proposes that future research can be extended from two existing streams: the institutional responses of project actors and the institutional outcomes of construction projects. This paper proposes several major questions that should be addressed by project management scholars working in both streams in order to develop an understanding of construction projects from an institutional perspective.

Originality/value

This is the first literature review of the existing body of knowledge based on a joining of institutional theory and construction project management literature. It uncovers knowledge gaps in contemporary research, notably a lack of broader consideration of how project actors respond to institutional environments and of the institutional outcomes of project management.

Abstract

Purpose

This paper aims to assess how enterprise resource planning (ERP) performance of Korean small and medium enterprises in manufacturing differs according to different levels of business process reengineering (BPR), information strategic planning (ISP) and ERP customization.

Design/methodology/approach

A questionnaire survey was carried out in this research. Responses from 96 small and medium manufacturing companies that have adopted ERP systems were analyzed.

Findings

The results of this study suggest that ISP and BPR implementation are positively correlated to ERP performance.

Originality/value

While consulting and customization costs have positive impacts on ERP performance, the level of customization does not influence performance. As one of the pioneering studies that investigate the impact of BPR, ISP and ERP customization on small and medium manufacturing companies, this research contributes to both theory and practice.

Abstract

Purpose

Contractor selection is critical in green buildings (GBs) since the preferred contractor has the responsibility to achieve construction sustainability as well as relationship sustainability. The developer satisfaction reflecting requirements can boost the cooperative relationship among stakeholders and act as an evaluation scale for the success of GB projects, which needs to be emphasized in the selection process but little involved in the existing research. This study explores improving GB contractor (GBC) selection by integrating developer satisfaction into selection procedures.

Design/methodology/approach

A systematic framework of GBC selection including twenty-five criteria from literature review and experts survey is firstly constructed. Both tactical and strategic criteria are further classified into Kano categories (must-be, one-dimensional, and attractive categories) using the fuzzy Kano model (FKM), and weighted by the developer satisfaction index. The model proposed by this study combining FKM and TOPSIS divides the selection process into the filtration phase and selection phase by Kano categories. The proposed model is finally verified through performance comparison among multiple methods in a case.

Findings

Selection criteria are measured linearly and nonlinearly, showing criteria having nonlinear satisfaction change accounts for two-thirds of all. Criteria at tactical level tend to be must-be or one-dimensional categories for the developer, and most strategic criteria are classed as the attractive category, indicating that adding strategic criteria is necessary for long-term cooperation. The proposed model, using developer satisfaction to improve the selection process, ensures the selected GBC to be the most satisfactory with requirements of the developer and makes the performance of GBCs easily distinguishable.

Originality/value

This study contributes to the existing body of knowledge for promoting relationship sustainability by supplementing an integrated model with emphasis on developer satisfaction in GBC selection, so as to establish a good initial foundation due to the match between performances of GBCs and needs of developers. It not only helps maximize developer satisfaction in GBC selection by applying satisfaction to pre-construction management, but also instructs GBCs to prioritize performance improvements. The framework is also conducive for developers to classify selection criteria and select other participants (like green suppliers) from the satisfaction perspective in GBs.

Abstract

Purpose

The purpose of this paper is to make a quantitative comparison between induction machine (IM) and interior permanent magnet machine (IPM) for electric vehicle applications, in terms of electromagnetic performance and material cost.

Design/methodology/approach

The analysis of IM is based on an analytical method, which has been validated by test. The analysis of IPM is based on finite element analysis. The popular Toyota Prius 2010 IPM is adopted directly, and the IM is designed with the same stator outer diameter and stack length as Prius 2010 IPM for a fair comparison.

Findings

The torque capability of IM is lower than IPM for low electric loading and competitive to IPM for high electric loading. The maximum torque/power-speed characteristic of IM is competitive to IPM; while the rated torque/power-speed characteristic of IM is poorer than IPM. The power factor of IM is competitive and even better than IPM for high electric loading in low-speed region. The torque ripple of IM is comparable to IPM for high electric loading and much lower than IPM for low electric loading. The overall efficiency of IM is lower than IPM, and the maximum efficiency of copper squirrel cage IM is approximately 2-3 percent lower than IPM. The material cost of IM is about half of IPM when IM and IPM are designed with the same stator outer diameter and stack length.

Originality/value

The electromagnetic performances and material costs of IM and IPM are quantitatively compared and discussed.

Abstract

Purpose

The purpose of this paper is to explore how a neo-liberal nationalist discourse of China imagines the spatial identity of the post-1997 Hong Kong with reference to Lost in Hong Kong, a new Chinese middle-class film in 2015 with successful box office sales.

Design/methodology/approach

Textual analysis with the aid of psychoanalysis, postcolonial studies and semiotics is used to interpret the meaning of the film in this study. The study also utilizes the previous literature reviews about the formation of the Chinese national identity to help analyze the distinct identity of the Chinese middle class today.

Findings

The discussion pinpoints how the new Chinese middle class as neo-liberal nationalists take Hong Kong as a “bizarre national redemptive space”. While Hong Kong is cinematically constructed as such a national other, this paper argues that the Hong Kong in question stands not for itself but in a form of “reverse hallucination” for pacifying the new Chinese middle class’ trauma under the rapid neo-liberalization of China in the 1990s.

Originality/value

This paper shows the new of formation of the Chinese nationalist’s discourse, especially the new Chinese middle-class discourse on Hong Kong after 1997.

Abstract

Purpose

The purpose of this paper is to carry out a numerical study on the dynamic and thermal behavior of a fluid with a constant property and flowing turbulently through a two-dimensional horizontal rectangular channel. The upper surface was put in a constant temperature condition, while the lower one was thermally insulated. Two transverse, solid-type obstacles, having different shapes, i.e. flat rectangular and V-shaped, were inserted into the channel and fixed to the top and bottom walls of the channel, in a periodically staggered manner to force vortices to improve the mixing, and consequently the heat transfer. The flat rectangular obstacle was put in the first position and was placed on the hot top wall of the channel. However, the second V-shaped obstacle was placed on the insulated bottom wall, at an attack angle of 45°; its position was varied to find the optimum configuration for optimal heat transfer.

Design/methodology/approach

The fluid is considered Newtonian, incompressible with constant properties. The Reynolds averaged Navier–Stokes equations, along with the standard k-epsilon turbulence model and the energy equation, are used to control the channel flow model. The finite volume method is used to integrate all the equations in two-dimensions; the commercial CFD software FLUENT along with the SIMPLE-algorithm is used for pressure-velocity coupling. Various values of the Reynolds number and obstacle spacing were selected to perform the numerical runs, using air as the working medium.

Findings

The channel containing the flat fin and the 45° V-shaped baffle with a large Reynolds number gave higher heat transfer and friction loss than the one with a smaller Reynolds number. Also, short separation distances between obstacles provided higher values of the ratios Nu/Nu0 and f/f0 and a larger thermal enhancement factor (TEF) than do larger distances.

Originality/value

This is an original work, as it uses a novel method for the improvement of heat transfer in completely new flow geometry.
