Abstract

Epidemiologists are concerned the next deadly global cognition will be a new kind of deadly flu which humans have no resistance. Since the 1960s, their alarm has been focused on a bird (avian) virus (H5N1). This virus is generally harmless in its host species, but it is extremely deadly when contracted by humans. H5N1 mutates quickly and tends to pick up genes from flu viruses that affect other species. The flu is far more contagious and harder to contain than the SARS (severe acute respiratory syndrome) virus. It is projected that 30‐40 per cent of the population would be infected in a H5N1 flu pandemic, and as many as one‐third would die. The 1918 Spanish flu caused 20 to 50 million deaths world wide. One scientist observed that the 1918 Spanish flu pandemic could have caused civilisation to disappear within a few weeks. Currently, more than 50 million chickens have been slaughtered in eight Asian countries in efforts to curb the spread of avian influenza. This article examines the roots and dangers of the potential avian influenza pandemic, examining the business and social ramifications that could ensue if the worst case scenario occurs.

Abstract

Purpose

Resilience concepts in integrated urban transport refer to the performance of dealing with external shock and the ability to continue to provide transportation services of all modes. A robust transportation resilience is a goal in pursuing transportation sustainability. Under this specified context, while before the perturbations, robustness refers to the degree of the system’s capability of functioning according to its design specifications on integrated modes and routes, redundancy is the degree of duplication of traffic routes and alternative modes to maintain persistency of service in case of perturbations. While after the perturbations, resourcefulness refers to the capacity to identify operational problems in the system, prioritize interventions and mobilize necessary material/ human resources to recover all the routes and modes, rapidity is the speed of complete recovery of all modes and traffic routes in the urban area. These “4R” are the most critical components of urban integrated resilience.

Design/methodology/approach

The trends of transportation resilience's connotation, metrics and strategies are summarized from the literature. A framework is introduced on both qualitative characteristics and quantitative metrics of transportation resilience. Using both model-based and mode-free methodologies that measure resilience in attributes, topology and system performance provides a benchmark for evaluating the mechanism of resilience changes during the perturbation. Correspondingly, different pre-perturbation and post-perturbation strategies for enhancing resilience under multi-mode scenarios are reviewed and summarized.

Findings

Cyber-physic transportation system (CPS) is a more targeted solution to resilience issues in transportation. A well-designed CPS can be applied to improve transport resilience facing different perturbations. The CPS ensures the independence and integrity of every child element within each functional zone while reacting rapidly.

Originality/value

This paper provides a more comprehensive understanding of transportation resilience in terms of integrated urban transport. The fundamental characteristics and strategies for resilience are summarized and elaborated. As little research has shed light on the resilience concepts in integrated urban transport, the findings from this paper point out the development trend of a resilient transportation system for digital and data-driven management.

Abstract

Purpose

While the investment in construction projects has increased over the past few decades, low construction project productivity (CPP) appeared to be persistent, thereby reflecting an “investment-in-failure” paradox between the investment and CPP. Hence, this paper aims to develop a systematic and holistic CPP evaluation framework to explain the apparent paradox in the construction industry.

Design/methodology/approach

The paper first reviews the literature about the theories of system, production, principal–agent and project success evaluation to re-conceptualise the CPP and proposes a two-stage CPP evaluation framework. The framework is subsequently explored through a sequential qualitative mixed-methods design within the context of the Hong Kong construction industry by combining 32 semi-structured interviews with senior industry experts and exploratory case studies, with three real-life construction projects.

Findings

The paper identifies three system boundaries for CPP evaluation, that is, parameter, timeframe and stakeholder, and develops a two-stage CPP evaluation framework to indicate site efficiency and utilisation effectiveness, thereby accessing the productivity of both the construction and post-construction stages. The “investment-in-failure” paradox associated with current CPP evaluation approaches is primarily attributed to the narrowly defined CPP boundaries.

Research limitations/implications

The qualitative exploration of the evaluation framework only focusses on the Hong Kong construction industry. Further case studies within other urban contexts could be used to improve the generalisability of the findings. Quantitative research is also necessary to advance theoretical development of the two-stage CPP evaluation.

Practical implications

The systemic CPP conceptualisation and the two-stage CPP evaluation framework support the systems thinking of industry stakeholders and enable them to formulate holistic strategies for long-term CPP enhancement.

Originality/value

The research demonstrates the needs to expand the system boundaries of CPP to reflect its systemic value and to shift the paradigm of CPP evaluation from being output-orientated and quantity-focussed to being outcome-orientated and value-focussed.

Abstract

This paper presents the outcomes of a study of the choice of location for distribution centres in logistics operations. A conceptual frame work of location selection for distribution centre is worked out through three main stages. At the first stage, a general geographical area for distribution centre is identified based on the Centre of Gravity principle, taking into consideration socio‐economic factors. The second stage of the selection process involves the identification of alternative locations for the distribution centre and the airports and seaports to be used for in bound and out bound cargo flows within the defined general geographical area. The third stage focuses on specific site selection among the identified alternative locations for the distribution centre based on the quantitative approach. This involves a mathematical model which aims to optimise either the total distribution cost or the integration of total distance transport with given relevant volumes of cargo. In order to illustrate the conceptual frame work, a case study of a logistics service provider will be provided. Data from the case study proved that the conceptual framework for selection is valid and can be of value to logistics companies in their operations and management.

Abstract

Purpose

Despite carbon reduction commitments, many constraints hinder the delivery of low-carbon buildings (LCBs) in high-rise high-density cities. The collaborative commitment of relevant stakeholders is vital to effectively address and mitigate these constraints. Hence, this study aims to comprehensively explore the required stakeholder collaboration attributes to address and mitigate the “common” constraints of delivering LCBs by focussing on several high-rise high-density cities.

Design/methodology/approach

A list of 21 “significant and common” constraints was identified through a systematic literature review followed by a questionnaire survey covering five economies (Hong Kong, Singapore, Australia, Qatar and the UAE). Nineteen influential stakeholders/stakeholder categories were identified through the literature, and their ability to influence the 21 constraints was mapped and identified through a two-round Delphi survey of 15 experienced professionals. The Delphi survey findings were analysed through social network analysis (SNA) methods to assess the stakeholder engagement and collaboration attributes.

Findings

The SNA results revealed the ability of stakeholders to influence the constraints, required collaborative stakeholder networks to address the constraints, significance of stakeholders according to the SNA centrality measures, core and periphery stakeholders and individual co-affiliation networks of core stakeholders.

Originality/value

While achieving the planned primary target of exploring stakeholder collaboration and their significance through SNA, this study also presents a useful sequential methodological approach for future researchers to conduct similar studies in different contexts. The findings also provide a foundation for accelerating the delivery of LCBs by strengthening stakeholder collaboration.

Abstract

Purpose

The purpose of this paper is to refine and expand technology adoption theory for a healthcare logistics setting by combining the technology–organization–environment framework with a business process management (BPM) perspective. The paper identifies and ranks factors impacting the decision to implement instances of technologies in healthcare logistics processes.

Design/methodology/approach

A multiple case study is carried out at five Danish hospitals to investigate the bed logistics process. A combined technology adoption and BPM lens is applied to gain an understanding of the reasoning behind technology adoption.

Findings

A set of 17 factors impacting the adoption of technologies within healthcare logistics was identified. The impact factors perceived as most important to the adoption of technologies in healthcare logistics processes relate to quality, employee work conditions and employee engagement.

Research limitations/implications

This paper seeks to understand how managers can use knowledge about impact factors to improve processes through technology adoption. The findings of this study provide insights about the factors impacting the adoption of technologies in healthcare logistics processes. Differences in perceived importance of factors enable ranking of impact factors, and prioritization of changes to be implemented. The study is limited to five hospitals, but is expected to be representative of public hospitals in developed countries and applicable to similar processes.

Originality/value

The study contributes to the empirical research within the field of BPM and technology adoption in healthcare. Furthermore, the findings of this study enable managers to make an informed decision about technology adoption within a healthcare logistics setting.

Abstract

Purpose

The zero carbon building (ZCB) approach has gained momentum in improving energy performance and reducing carbon emissions. Despite policy promotion for achieving zero carbon, innovative business models (BMs) are needed to overcome the challenges and accelerate the ZCB uptake. However, little research has examined ZCB and BM in tandem, and business strategies for ZCB delivery. The purpose of this paper is to explore the theoretical relations between BM and ZCB.

Design/methodology/approach

Drawing on a critical review of the definitions, components, and theoretical bases of BM and ZCB, this paper develops a conceptual model that maps out the multifaceted interrelations between ZCB and BM at both project and organisational levels.

Findings

The results discover co-productive interrelations between BM and ZCB in four aspects, namely, value offering, project delivery process, stakeholder network, and revenue generation logic. Innovative BMs address the socio-technical challenges to delivering ZCBs through innovating BM components, while ZCB provides a new paradigm of organisational-level systems to BM innovations as a source of corporate competitiveness.

Practical implications

The findings will be of immense benefit to the decision makers of construction organisations in enhancing their business strategies for successful ZCB deliveries, and help to de-risk business innovations and ZCB take-up for their maximised synergies.

Originality/value

The findings contribute a novel approach to disentangling the complex co-productive interrelations between BM and ZCB. This review calls for a step change in future research into the two important areas, BM and ZCB, in an interrelated manner.

Abstract

Purpose

The purpose of this paper is to investigate the complex interdependence of the factors in driving or hindering construction productivity at the industry, project and activity levels in a systemic manner.

Design/methodology/approach

A mixed-methods design, which combines a critical literature review, an interview-based survey with 32 industry experts and five focus group meetings participated in by 109 representatives of a wide range of industry stakeholder groups, was employed to identify the drivers for and constraints on construction productivity enhancement in Hong Kong and explore the interrelated insights into the drivers and constraints.

Findings

The study conceptualised and validated a systemic framework for examining construction industry productivity, and developed three causal loop diagrams (CLDs) for illustrating the dynamic structures that underpin the complex systems of the drivers and constraints.

Research limitations/implications

Although the scope of the study was limited to Hong Kong, the results could be interpreted for critical learning in other urban contexts.

Practical implications

The systemic perspective of construction productivity and the CLDs of the drivers and constraints support the systems thinking of industry stakeholders in the formulation of holistic strategies for long-term construction industry productivity enhancement.

Originality/value

The study conceptualises construction productivity from a systemic perspective and provides empirically supported CLDs to facilitate future investigations into the complex system of construction productivity.
