Abstract

Purpose

This paper develops a platform that can be used to determine how to effectively and efficiently deal with a large number of temporary facilities under a constrained site condition(s). The ultimate goal is to reduce the material handling costs between transformation phases of construction works occurring during the project's development period.

Design/methodology/approach

Empirical and deductive research is first adopted to mathematical model dynamic site layout planning using the branch and bond algorithm (B&B). Second, a real-life construction project is examined to illustrate how dynamic site layout planning (using the aforementioned B&B algorithm and a computer software program called LINGO) can reduce the material handling costs. The application of the proposed methodology is then showcased against a case study that utilizes a comparative analysis between the “dynamic” and “statistic” site planning approaches.

Findings

By dividing the construction period into different phases, the developed model is shown to be capable of optimizing the material handling costs between the phases of transformation during construction works. Optimal costs are also considered using the site boundary and unit cost for moving construction materials between two facilities. The comparative analysis results illustrate that the B&B algorithm reduces material handling costs by 33%.

Practical implications

The proposed model offers an effective planning algorithm for the site layout and location of temporary facilities. More specifically, it can make a substantial improvement in reducing the travel time and material handling cost between the temporary facilities in the construction sites.

Originality/value

The primary knowledge contribution of this study to the site layout is successfully deal with the unequal area problem of temporary site facilities and incorporates the concept of dynamics site planning into the algorithm.

Abstract

Purpose

Owing to limited space, reducing the waste going to landfills has become a pressing issue in Hong Kong. As most of the solid waste was generated from construction activity, the Hong Kong Government has instituted a number of measures aimed at reducing waste from this source. However, it appears that the application of these measures has been of limited effectiveness. Therefore, the purpose of this paper is to examine the effectiveness of implementing regulatory measures for reducing construction waste in Hong Kong.

Design/methodology/approach

The data used for the analysis are from a survey to construction professionals in the local industry by means of questionnaire, interview discussions and case studies. The survey examined the commitments and responsibilities imposed on project participants for implementing seven major regulatory waste management controlling measures: legislative controls; controlling public filling facilities; controlling landfill areas; providing on‐site sorting facilities; implantation of a environmental management system; implementation of a waste management framework plan; and implementing recycling scheme.

Findings

The results of the investigation illustrate that legal commitments have been mainly allocated to contractors. Insufficient commitments and responsibilities are allocated to other project participants such as project clients, designers and consultants. The study has also found that existing waste control ordinances allow for skewed distribution of commitments and responsibilities of controlling construction waste among project stakeholders. The results demonstrate that there is need for a balanced allocation of responsibilities and commitments among all project stakeholders.

Originality/value

Revision and further development of legal measures are necessary to ensure that all project stakeholders play an active role and share commitments in waste control and reduction. This research provides references for studying construction waste management in other construction industries.

Abstract

Purpose

This study aims to identify and map the problems of participatory processes in policymaking through a Service Design approach.

Design/methodology/approach

First, 50 semi-structured interviews were conducted with experts in the field of citizen participation. This was followed by a comparative analysis of how backstage and frontstage stakeholders perceived the identified problems. Secondly, a Service Blueprint model was proposed as a means of mapping the identified problems within the broader framework of a service experience of participation. Finally, a brainstorming session was held with the aim of proposing design solutions to the problems from a human-centred perspective.

Findings

Fifteen problems of participatory processes in policymaking were identified, and some differences were observed in the perception of these problems between the stakeholders responsible for designing and implementing the participatory processes (backstage stakeholders) and those who are called upon to participate (frontstage stakeholders). The problems were found to occur at different stages of the service and to affect different stakeholders. A number of design actions were proposed to help mitigate these problems from a human-centred approach. These included process improvements, digital opportunities, new technologies and staff training, among others.

Practical implications

Public managers, politicians and designers of participatory processes can use this study to design participatory processes based on the real needs and expectations of the different stakeholders involved.

Originality/value

This research adds to the literature on citizen participation and Service Design by shedding new light on the problems of participatory processes through a human-centred approach.

Abstract

Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract

Purpose

The aim of this paper is to investigate the effectiveness of the enhanced school facilities and the impacts of this enhancement on the learning behaviors of students

Design/methodology/approach

A pre‐ and post‐occupancy evaluation questionnaire was administered in 2003‐2004 to 750 primary students who had studied in both the old schoolhouses and the new Millennium Schoolhouses.

Findings

The results revealed that all of the FM components except teaching tools were improved in the millennium schools, while most of the learning behaviour (LB) components showed no changes. However, an interesting finding was that most of the improved FM components correlated to the enhanced LB of the students in the millennium schools.

Research limitations/implications

There was only a three to four months period between the pre‐ and post‐occupancy evaluation in the study. To ensure the effectiveness of upgraded FM in millennium primary schools and to understand the long‐term impacts on the learning outcomes of students, a longitudinal post‐occupancy evaluation study in these three millennium schools is recommended.

Practical implications

It is suggested that a longitudinal POE study be conducted in these three millennium schools in order to understand the long‐term impact of facilities management in millennium primary schools, especially the impact on the academic performance of students.

Originality/value

Architects and facilities managers should further discuss with teachers about how to encourage students in classrooms to be self‐disciplined, redesign the layout, and reconsider the teaching tools that today's primary students need.

Abstract

Purpose

Over the past decades, the global solar photovoltaic (PV) market has experienced an unprecedented development associated with a substantial decline in solar PV module prices. A body of literature has attempted to identify and evaluate the different sources of price variation. However, the impact of international trade on the price of solar PV modules has not yet been empirically examined. This paper contributes to filling this gap in the literature by providing a comprehensive empirical examination on the relationship between international trade and solar PV module prices.

Design/methodology/approach

The author uses a sample of 15 countries over the period 2006–2015 and proposes a linear dynamic panel data model based on a new specification, including a number of relevant factors influencing solar PV module prices.

Findings

The empirical analysis reveals that an increase in imports of solar PV cells and modules is associated with a decline in solar PV module prices. This finding suggests that international trade could lead to further price reductions, thus fostering the deployment of solar PV technology. The study reveals several other important findings. Market and technological development are key factors explaining the decline in solar PV module prices. Moreover, government policies such as public budget for R&D in PV and feed-in tariff for solar PV are effective in reducing the price of solar PV modules.

Originality/value

This paper examines the influence of international trade, government policies, market development and technological development on solar PV module prices. The results may be of interest to both academic research and policy analysis.

Abstract

Purpose

According to many authors, differences in firm performances are increasingly attributed to tacit knowledge that cannot easily be transmitted or imitated. On the other hand, current quality management models knowledge typically relates only to people. Situations, in which knowledge that is related to people is not available, sufficient, reliable or lucrative for application, are not considered. This paper aims to investigate how to overcome this gap.

Design/methodology/approach

Based on the adopted classification, types of knowledge typically present in an organisation are identified, and are discussed. Techniques for acquiring and formalising tacit knowledge are explored, and related criteria are defined. Particular attention is shown to knowledge management and artificial intelligence techniques.

Findings

A new approach to quality management called deep quality concept (DQC) is conceptualised, and mechanisms and concepts needed to acquire and integrate formalised knowledge into quality systems are identified. Other concepts that need to be incorporated are also identified. Finally, a new quality management model based on the DQC is developed.

Research limitations/implications

In further research the main points of the presented theoretical framework need to be validated through real examples from practice, and the resulting quality standard, i.e. award criteria, as well as the related handbooks completed and formalised.

Practical implications

Knowledge‐related and other relevant concepts need to be incorporated into contemporary quality management systems, as systematically and carefully as conventional quality management concepts. Knowledge of methods and tools suitable for that also needs to be assimilated.

Originality/value

In the paper a novel knowledge‐focused approach to quality management is presented. For this reason the paper is of great value for quality management theory and practice.

Abstract

Purpose

The objective of this study is to address the diplomatic and economic implications of the participation of Latin America and the Caribbean (LAC) countries in the Belt and Road Initiative (BRI).

Design/methodology/approach

The study examines official documents related to the BRI and LAC's signing of the Memorandum of Understanding within the framework of the BRI (MoUs) in order to look into what it means to join the BRI. Additionally, it also introduces the findings of articles in Asian Education and Development Studies' current issue published in 2020.

Findings

In LAC, the BRI does not represent a new policy, but rather the updating and rebranding of a pre-existing one. The BRI primarily consists of an official discursive framework which aims to build a coherent narrative for a wide range of different projects and policies geared toward the improvement of connectivity with China through the development of trade and investments. However, most of these projects were implemented prior to the BRI. Pragmatism lies at the core of this framework which neither has a regulated accession process nor any binding effects. As a result, the signing the MoU represents, foremost, a diplomatic mise-en-scène. The study operates under the belief that BRI membership is not dichotomous; rather, it must be observed in terms of the countries' level of participation. In line with this, the implementation of a generalized BRI policy in LAC countries would not be advisable. Moreover, it must be noted that the BRI's reach to Latin America can be rather problematic due to the fact that the latter was not initially a participant.

Originality/value

The study aims to explore the significance of the BRI beyond the official discourse and discuss the involvement of LAC countries in it. Scholars studying the BRI in other regions have noted that there is not enough information on this policy in the context of LAC.
