There is an impressive amount of individual research projects examining the vulnerability of critical infrastructure network. However, there is little understanding of the totality of the contribution made by these projects and their interrelationships. This makes their review a difficult process for both new and established researchers in the field. To address this issue, a two-step literature review process is used to provide an overview of the vulnerability of the transportation network in terms of four main themes—research objective, transportation mode, disruption scenario, and vulnerability indicator—involving the analysis of related articles from 2001 to 2013. Two limitations of existing research are identified: (1) the limited amount of studies relating to multilayer transportation network vulnerability analysis, and (2) the lack of evaluation methods to explore the relationship between structure vulnerability and dynamical functional vulnerability. In addition to indicating that more attention needs to be paid to these two aspects in the future, the analysis provides a new avenue for the discovery of knowledge, as well as an improved understanding of transportation network vulnerability.

The VEC and the multiple linear regression analysis in forecasting can better capture the causal relationship between the construction manpower demand and the associated factors.Practical implicationsAccurate predictions of the level of manpower demand are important for the formulation of suc...

This research seeks to identify and empirically validate measures of effective risk management (ERM) in the context of PPPs in a developing country, a subject that has received scant attention in the extant literature. The research is based on a comprehensive literature review, expert interviews and a questionnaire survey. Mean score ranking and factor analysis were employed to rank and group the identified measures, respectively. Tests were performed to determine the respondents’ agreement and establish the reliability and validity of the survey instrument. Analysis results indicate that all identified measures are important, are distributed over the entire project’s life cycle and exhibit a multi-organizational focus. The most significant measures focus on PPP-specific artifacts and procurement activities that are vital for ERM. Factor analysis establish...

The rapid population growth and urbanization have resulted to the increase in demand for housing ... more The rapid population growth and urbanization have resulted to the increase in demand for housing units in developing countries. Therefore, most governments have sorted to the application of the public-private partnership (PPP) scheme. Like other developing countries, the Government of Ghana (GoG) has also attempted to implement the PPP policy for affordable housing with the high-profiled project; The Ghana National Housing Project (GNHP). However, this project failed, as it was not implemented. This paper aims to review the underlying challenges of implementing PPP policy for affordable housing delivery in Ghana by analysing the experience of the GNHP. From the case study analysis, a conceptual success model for implementing the PPP policy for affordable housing delivery in Ghana is proposed. The model consists of five categories of success factors; these are national policy on housing PPP, transparency and competition, capacity building, stakeholder engagement and the use of local labour and materials. The outputs of this study are considerably beneficial to policy makers and private housing developers. They inform practitioners on the investment strategies to adopt for future housing PPP projects in Ghana

For example, in Australia, between 1993 and 2013, the percentage of people aged 65+ has increased from 11.6% to 14.4% (Australian Bureau of Statistics 2013). In fact, the proportion of older Australians has been projected to increase to 20% by 2056 (Bo et al. 2015). Also, in China, specifically Shenzen, it has been projected that by 2020, the ageing population will reach 10% of the total population in the city (Zhen 2016). Essentially, the rapid demographic ageing globally has put a lot of pressure on many social amenities including housing (Hu et al. 2017). Currently, there are many housing options for older adults; however, a significant proportion of them prefer to live independently in a retirement village. This is because retirement villages or otherwise called aged care homes have been noted to be agefriendly compared to family homes. Retirement villages usually have a range of on-site household facilities and support services such as libraries, hairdressing saloons, transportation, etc. (NSW Government 2017; Liu et al. 2018)

Many governments are now very enthusiastic about the concept, and different governments have varying motivations for adopting the policy. Nonetheless, developing countries have huge infrastructure deficit coupled with rapid urbanization growth; therefore, the PPP concept is seen to offer huge relief. However, it should be mentioned that despite the commitment shown by many governments in developing countries, more projects are yet to be fully implemented. Developing countries are currently facing numerous challenges including corruption, lack of transparency and competition, risk misallocation, poor value for money, public agitations, and political opposition (Osei-Kyei and Chan 2015)

This paper provides an initial report of a research project funded by the Research Grants Council (RGC) of the HKSAR to address this safety issue. The aim of this study is to scrutinize the causal relationship between safety climate and safety performance in the RMAA sector. It aims to evaluate the safety climate in the RMAA sector; examine its impacts on safety performance, and recommend measures to improve safety performance in the RMAA sector. This paper firstly reports on the statistics of construction accidents arising from RMAA works. Qualitative and quantitative research methods applied in conducting the research are dis-cussed. The study will critically review these related problems and provide recommendations for improving safety performance in the RMAA sector

This necessitates exploring the root causes of such accidents as well as identifying the significant safety climate (SC) factors that can positively influence the safety performance (SP) in the Pakistani construction industry (CI). For this study, a mixed-method research strategy comprising concurrent and sequential research methods was adopted. The study concludes that accidents in the Pakistani CI can be reduced by strict enforcement of safety rules and regulations by government agencies; guaranteed provision of a safety budget; and the introduction of safety incentives by the clients, adequate provision of safety training and resources by the contractors, and giving due importance to past SP while selecting the subcontractors. A 24-item SC scale, comprised of four SC factors, was developed and validated for the Pakistani CI. The study also verified the significant positive impact of SC on safety compliance and safety participation , and the negative impact on the number of self-reported accidents/injuries. The analysis of demographic variables confirmed that the employees in the age group of 20 years or below, and working for more than 40 hours per week, have a tendency towards unsafe behaviour. The study adds to the body of knowledge by highlighting the implications of adopting an existing SC scale across the region and culture, and revealing the deviations in SC dimensions. Caution should be exercised while generalizing the research findings to other sectors of CI. Nonetheless, the study's robust methodology can be replicated in other industries and regions for element prioritization and SC investigation. https://doi.org/10.1201/9780429455377https://www.taylorfrancis.com/chapters/strategies-enhance-safety-performance-construction-industry-pakistan-hafiz-zahoor-albert-chan/e/10.1201/9780429455377-6

This paper explores the perceptual differences on the success criteria for PPP projects among PPP stakeholders. A questionnaire survey was conducted with targeted international PPP experts from the academic, public and private sectors. The research findings show that each stakeholder group considers effective risk management as the most critical success criterion. Moreover, the public and private sectors consider meeting output specifications as the second most critical criteria, whereas the academic sector considers satisfying the need for public facility/service. Further analysis using non parametric tests shows significant differences on the ranking of the criterion, “satisfying the need for public facility/service” between the public and private sectors and between academic and private sectors.

Different governments have different reasons for adopting the PPP concept. This paper aims to investigate the differences and similarities on the reasons for implementing PPP in develop-ing and developed economies/countries, represented by Ghana and Hong Kong. An empirical questionnaire survey was conducted with relevant experienced practitioners in both jurisdictions. One hundred and three completed questionnaires were returned for analysis. The results from the non-parametric test show five reasons with significant differences. Reasons related to the economic and social benefits of PPP are ranked higher in Ghana, whereas efficiency and quality service related reasons are ranked higher in Hong Kong. Further, two reasons for adopting PPP emerged as very important in both jurisdictions; these include: “promotes quick delivery...

Using a two-stage methodological process to identify the relevant publications needed, 39 unique ACMs were identified in 38 selected publications. The leading ACMs identified are ethical codes, transparency mechanism, training, and development initiatives. A conceptual framework constituting six thematic constructs was developed to facilitate easy identification of ACMs and categorization of future developments of ACMs. They are regulatory, managerial, probing, compliance, promotional, and reactive measures. The findings contribute in-depth understanding of ACMs in CPM and are useful for further empirical research.

However, over the past years, most of the developing countries have failed to attract more private investments as realised in the developed countries. This paper aims to investigate the critical factors that attract private investments in the PPP markets of developing countries. Design/methodology/approach An empirical questionnaire survey was conducted with targeted international PPP experts from the academic and industrial sectors. The inter-rater agreement analysis, mean score ranking and Mann–Whitney U test were used to analyse the survey responses. Findings Results indicate that the three most critical factors are political support and acceptability for PPPs, government positive attitude towards private sector investments and political stability. On the other hand, factors including government guarantees, competent PPP unit and tax re...

However, such arrangements present their own set of challenges which are primarily attributable to the complex organizational structures and long duration of underlying contractual relationships. In particular, the need for effective risk management becomes all the more important to ensure a successful project and a lapse in this domain is known to deliver disastrous outcomes. Pakistan, a developing country with a large population, abundant natural resources and geopolitical significance, boasts all the drivers to promote and benefit from PPPs. It also harbors elements that expose the stakeholders to significant risks. Therefore, a research framework is developed to identify critical risks, determine risk allocation practices, develop robust models for efficient project risk assessment and allocation, and determine measures to ensure efficient risk management on future PPP projects. Existing literature is reviewed and summarized to determine the significance, drivers, barriers, and risk management characteristics of infrastructure PPPs in the Pakistani context. In addition, results of the preliminary interviews with experts have uncovered multiple lifecycle risks and suggest immature and unsystematic risk management practices, which subsequently inform the development of the research framework.
