A Scientometric Analysis of Studies on Risk Management in Construction Projects
Full text linkRisk management is one of the topical areas in construction project management research. However, no attempt has been made in the past decades to explore the emerging themes in this area. This paper reviews the research trends in risk management in construction. The bibliometric data of 1635 publications between 1979 and 2022 were extracted from Scopus using a set of keywords. The study used VOSviewer and Gephi to conduct a scientometric analysis on the extracted publications. The review outcome indicates a significant increase in publications on risk management in construction, with about 205 publications recorded between 2021 and 2022 alone. Based on this analysis, it is projected that the next decade will see significant research on risk management, especially as the construction industry moves towards Industry 5.0 with many uncertainties. Further, the most productive countries of risk management studies in construction include China, the United States, the United Kingdom, Australia, and Hong Kong. Emerging key research areas are discussed using network diagrams and clusters. These areas include the processes in risk management, risk analytical models and techniques, sources of risk and uncertainties, effective knowledge-based systems for improved risk management, risk contingency in construction contracts, risk-integrated project planning and scheduling, and stakeholder management. The findings of this study inform researchers on the current progress of risk management studies in construction and highlight possible research directions that can be considered
Critical analysis of the emerging flood disaster resilience assessment indicators
No full textPurpose: The world is reeling from the effects of climate change with increased extreme precipitation. Flooding is amongst the most recurring and devastating natural hazards, impacting human lives and causing severe economic damage. This paper aims to conduct a systematic review to critically analyse the most reported and emerging flood disaster resilience indicators. Design/methodology/approach: A total of 35 papers were selected through a systematic process using both Web of Science and Scopus databases. The selected literature was subjected to a thorough thematic content analysis. Findings: From the review, 77 emerging flood disaster resilience assessment indicators were identified. Furthermore, based on the individual meanings and relationships of the derived indicators, they were further categorized into six groups, namely, physical, institutional, social, psychological, ecology and economic. More also, it was identified that most of the selected publications have used objective resilience measurement approaches as opposed to subjective resilience measurement approaches. Originality/value: The generated list of flood disaster resilience indicators will provide insights into the capacities which can be improved to enhance the overall resilience to flood disasters in communities
Critical review of the drivers and barriers for adopting net zero carbon procurement for construction projects
Full text linkTo meet the net zero 2050 target in construction, a net-zero carbon public procurement policy is needed. This paper adopts a systematic review approach to explore the drivers and barriers to adopting net-zero carbon procurement. The top three drivers include developing sustainable public procurement policies, increasing investment in low-carbon procurements, and high demand for green construction projects. The top three barriers include inadequate budget for net-zero procurement implementation, weak capacity in public and private institutions to implement net-zero policies, and low stakeholder involvement. The paper's findings provide insights for stakeholders to effectively adopt net-zero carbon procurement for construction projects
Pandemic risks in PPPs: comparative analysis within developing countries
No full textGlobally, Public-private partnerships (PPPs) become a widely adopted method for advancing large-scale infrastructure projects. However, the inherent uncertainties and risks associated with these projects represent a significant managerial challenge, particularly when confronted with unforeseen events such as those triggered by COVID-19. This paper aims to identify and assess risk associated with the pandemic in PPPs in developing nations through a specific form of mixed-methods research, an embedded multiple-case study, involving the PPP programs in two developing countries in Central Asia and Latin America. Through a comprehensive analysis of risk assessment (including probability, severity, and impact) and applying Kendall’s concordance and Cronbach’s alpha tests with the SPSS 26 tool, a comparative examination of these risks between the two countries is conducted. Complementary, the embedded cases were analyzed through the triangulation of project reports, governmental websites, SPV websites, and interviews. The findings reveal variations in risk perception and priorities, with less mature PPP programs displaying higher risk aversion and concerns regarding project disruptions; and more developed programs seeking to address short-term liquidity challenges. Risk management strategies are proposed for PPP decision-makers to face unforeseen events more effectively
Critical success criteria for retirement village public – private partnership housing
No full textPurpose: The demand for retirement villages globally has been increasing due to the rapid growth in the ageing population in recent years. To address the rising challenges in the retirement market, the public–private partnership (PPP) has become a feasible method to develop retirement villages. This paper aims to survey and examine the key success criteria (SC) for using the PPP approach in the retirement village sector. Design/methodology/approach: An empirical questionnaire survey was conducted with experts experienced in international PPP and retirement village. The analysis was conducted using one-way analysis of variance, mean score analysis, Kendall’s coefficient of concordance and factor analysis. Findings: Results indicate that out of the 16 recognized SC, the most significant ones are SC1: “Affordability”, SC11: “Reduced social isolation of residents” and SC14: “Improvement of emotional wellbeing of residents”. Furthermore, results from the factor analysis technique indicate that the 16 SC can be classified into five major factor groupings, and these include SCG1 – “Financial performance of project”; SCG2 – “Adherence to design and technical specifications”; SCG3 – “Adherence to local council/authority’s environmental health and socio-economic requirements”; SCG4 – “Social inclusion and risk management”; and SCG5 – “Advancement in emotional wellbeing and physical health of residents”. Originality/value: The study will sufficiently assist retirement village stakeholders, retirement village project participants and related government authorities of the best measures to put in place to maintain the sustainable development of the global retirement village market
Building urban community resilience against hazards through public-private partnerships : a review of critical resilience strategies
Full text linkThe need for governments and stakeholders to find urgent solutions to address the destructive effects of disasters in urban areas has led to the call for cross-sector collaborations such as public-private partnerships to assist with the development of urban community resilience in this modern era. This paper comprehensively reviews studies on the critical strategies in using public-private partnerships as a collaboration mechanism in building urban community resilience. Through a two-stage systematic literature review process, 83 publications related to PPPs and urban community resilience were retrieved for thorough content analysis. Based on an analysis of the literature, 35 critical resilience strategies for using PPPs in building urban community resilience were derived. These strategies were further categorized into nine major groupings. These groups include vulnerability and risks assessment, information gathering, database, legal, monitoring and evaluation, resilience capacity, communication and coordination, financial incentives, and business continuity. Furthermore, a theoretical framework was developed. These resilience strategies can be adopted by states and communities that intend to use the PPP concept to build the resilience of their urban communities. It also opens the international debate on the suitability of the PPP model for community resilience building
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
