Value creation for society from public projects requires that the overall benefits exceed the use of taxpayers' money. At the same time, cost overruns in public projects are a well-documented feature in the literature, but practical guidance on reducing the extent and magnitude of overruns is rare. In 2000, Norway introduced a governance regime that includes mandatory external quality assurance (QA) of cost estimates for major public projects. This paper compares the cost performance of public projects on each side of this QA scheme.

We use an original dataset covering 1,704 projects from 2000 to 2021, reported first-hand from Norwegian public agencies. We apply quantitative methods in the form of descriptive statistics, regression models, and statistical testing of hypotheses to answer our research questions.

The mean cost overrun across projects in our dataset is smaller than several previous international studies have reported. We find no statistical support for different cost performances between QA and non-QA projects. Secondly, cost overruns seem to vary between different public sectors. A third finding is a small development with lower cost overruns over time for the non-QA projects, and we raise the question of whether the QA scheme has contributed to overall learning effects. The fourth finding is that cost deviations are quite independent of project size.

The paper offers novel insights for decision-makers and researchers on the effects of external quality assurance on cost performance in public projects.

Research shows that there are mechanisms of information simplification that lead to the danger that first, laypeople rely on their own epistemological skills when assessing scientific claims. Second, laypeople underestimate their dependence on experts when they receive simplified information. This underestimation can be problematic because scientific knowledge, due to its complexity, usually cannot be fully understood without further advice from experts. Compared to laypersons, adult education practitioners can be expected to have a higher level of scientific literacy in relation to knowledge in their professional field because they are familiar with the structure of knowledge through their formal education. The present study examines whether the “easiness effect” also occurs in adult education practitioners when they read simplified and highly simplified texts about research findings.

The sample consisted of 1.267 continuing education institutions. For the survey experiment, particioants were randomly assigned to tree text types at the end of the survey: easy, less scientific and scientific text. We used the difference-in-difference method to analyze the data.

The study examined whether easily presented research findings influenced self-assessment and reliance on experts. The results of our study support the hypothesis that the easiness effect is also present among professional practitioners.

The use of clear and nontechnical language is essential for ensuring that scientific knowledge is accessible and utilizable outside of academic circles. This aspect gains particular significance in educational research, as it enables professional practitioners to comprehend and ideally implement, research findings in their daily routines to address and resolve real-world challenges in their educational environments. Previous studies have demonstrated that the way text is presented influences laypeople's perceived reliance on experts. Building upon the conceptual framework of the easiness effect, this survey experiment took an additional step by focusing specifically on a targeted audience: professional practitioners in adult education.

This research aims to develop and validate a framework for eradicating women’s discrimination in architectural design firms (ADFs) in Egypt and propose strategies for prospective adoption in the Gulf Cooperation Council (GCC) countries to increase the transformational impact of women on the architectural and urban developments of the Gulf region.

A combined qualitative and quantitative research approach was designed to accomplish four objectives. Firstly, to investigate the nature of business in ADFs, women’s discrimination and policies for gender equity (PGE) in architecture. Secondly, to analyse three case studies to validate the identified causes and impacts of women’s discrimination and examine the role of PGE towards eradicating women’s discrimination in ADFs. Thirdly, to conduct a survey questionnaire with a representative sample of ADFs to investigate their perception of women’s discrimination and the correlation between PGE towards eradicating women’s discrimination in ADFs. Based on the above, the research developed and validated a framework to eradicate women’s discrimination in ADFs in Egypt and suggested strategies for potential application in the GCC countries to increase the transformational role of women in the architectural and urban developments of the Gulf region.

Through literature review and case studies, the research identified and validated the causes and impacts of women’s discrimination as well as PGE in Architecture. The findings of data analysis showed that the highest-ranked causes of women discrimination in ADFs were “customs and beliefs” followed by “Underestimating women’s work” and “Recruiting males more than females”. Moreover, the highest-ranked impacts of women’s discrimination were “career shift and leaving the profession” followed by “decrease in creativity and innovation” and “decrease in economic growth”. Furthermore, the Spearman correlation test showed that while some PGE were correlated, others were not. These findings helped in the development of the proposed framework and proposed strategies.

This research presents a practical framework to eliminate women’s discrimination in ADFs in Egypt based on the findings of literature review, case studies and survey questionnaire. The framework explained in a workable way the objectives of the framework functions; activities; tools and techniques; involved personnel and needed resources as well as enforcing mechanisms. It was validated by a representative sample of ADFs in Egypt to ensure its practicability and viability and suggested strategies for implementation in the GCC countries to increase women’s role in architectural and urban development.

The research identified and validated the causes and impacts of women’s discrimination as well as PGE in Architecture. Moreover, the research investigated the perception of women’s discrimination and the correlation between PGE through conducting a survey questionnaire with a representative of ADFs in Egypt. The research tackled a topic that received scant attention in construction literature, especially in Egypt and the GCC countries. The research developed and validated a framework to eradicate women’s discrimination in ADFs in Egypt. It represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred. The research suggested several strategies for the prospective implementation of the framework in the GCC countries as an approach to enhancing the transformational role of women in the architectural and urban developments of the Gulf region.

The current estimation practice in construction projects greatly needs upgrading, as there has been no improvement in the cost overrun issue over the past 70 years. The purpose of this research was to develop a new multiple regression analysis (MRA)-based model to forecast the final cost of road projects at the pre-design stage using data from 43 projects in New Zealand (NZ).

The research used the case study of 43 completed road projects in NZ. Document analysis was conducted to collect data, and statistical tests were used for model development and analysis.

Eight models were developed, and all models achieved the required F statistics and met the regression assumptions. The models’ mean absolute percentage error (MAPE) was between 21.25% and 22.77%. The model with the lowest MAPE comprised the road length and width, number of bridges, pavement area, cut and fill area, preliminary cost and cost indices change.

The model is based on road projects in NZ. However, it was designed to be able to adapt to other contexts. The findings suggest that the model can be used to improve traditional conceptual estimating methods. Past project data is often stored by the project team but rarely used for analysing and forecasting purposes. This research emphasises that past data can be effectively used to predict the project cost at the pre-design stage with limited information.

No research was conducted to adopt cost modelling techniques into the conceptual estimation practice in the NZ construction industry.

Businesses are increasingly vulnerable and exposed to physical climate change risks, which can cascade through local, national and international supply chains. Currently, few methodologies can capture how physical risks impact businesses via the supply chains, yet outside the business literature, methodologies such as sustainability assessments can assess cascading impacts.

Adopting a scoping review framework by Arksey and O'Malley (2005) and the PRISMA extension for scoping reviews (PRISMA-ScR), this paper reviews 27 articles that assess climate risk in supply chains.

The literature on supply chain risks of climate change using quantitative techniques is limited. Our review confirms that no research adopts sustainability assessment methods to assess climate risk at a business-level.

Alongside the need to quantify physical risks to businesses is the growing awareness that climate change impacts traverse global supply chains. We review the state of the literature on methodological approaches and identify the opportunities for researchers to use sustainability assessment methods to assess climate risk in the supply chains of an individual business.

There is a limited number of research work on critical success factors (CSFs) in public construction projects in Saudi Arabia. In response to this knowledge gap, the objective of this paper is to assess the impact of CSFs on the government construction projects in Saudi Arabia. The success factors are investigated from a broader consideration of failure criteria, from consideration of most effectiveness in successful project completion and also from consideration of the impact of implementing control processes for successful project completion.

This study has analysed the impact of success factors on construction projects in Saudi Arabia using a descriptive methodology. An exhaustive literature survey is undertaken to identify the success and failure factors related to government construction projects in Saudi Arabia. The survey data are sorted out and analysed by cost, schedule, technical, context and finance dimensions of the projects based on project types, engineering complexity, size, modality, jurisdictional control and funding approach. To evaluate the influence of success factors implementation, qualitative data were collected in a survey via a web-based questionnaire that was sent to officials working and occupying a responsible position in national project guidelines organizations and in government construction organizations in Saudi Arabia. In all, 28 CSFs were identified, ranked and evaluated for their impact on project success. The four identified factors belong to process categories of construction projects, nine factors belong to management of construction projects and 15 success factors are identified for impact assessment of implementation in construction projects.

The study's findings have identified and ranked the top five CSFs that significantly influence project outcomes, including meeting time targets, adhering to financial budgets, delivering desired outcomes for all stakeholders, effectively managing risks and assembling the appropriate team while optimizing resource allocation. Additionally, the research indicates that hindrances to projects primarily stem from execution, economic, human and political factors. The study advocates for strict controls over incomplete engineering designs and advises against contractors independently handling design work to ensure project success. Additionally, addressing contractors' qualifications and financial matters is crucial for project success. By highlighting these CSFs and challenges, the research provides actionable insights to enhance project management practices in the construction industry.

This study is limited to the infrastructure projects constructed by governmental bodies with the participation of officials from government organizations. Further study, including private projects and officials working on private projects, may be needed to generalized the research outcome.

Numerous studies have investigated CSFs in construction projects, but few have examined their relevance to Saudi Arabian government projects. This study aims to fill this gap by identifying key CSFs specific to Saudi Arabian public sector construction projects and assessing their impact on project success. It advocates for stringent controls in the Saudi Arabian construction sector, emphasizing the importance of preventing incomplete or altered engineering designs by contractors to increase the success rate of public sector projects. This research offers practical insights to stakeholders, advancing project management practices in Saudi Arabia's construction sector for improved outcomes and resource utilization.

This study investigates how environmental, social, and governance (ESG) factors influence intangible asset and intellectual capital valuation within the food and beverage (F&B) industry. By examining and contrasting global and European contexts, the research highlights ESG’s critical role in shaping the economic dimensions of sustainability across different regulatory environments. The results provide essential insights for stakeholders aiming to enhance corporate value through responsible business practices.

We adopt a quantitative fixed-effects panel regression analysis for ESG performance and intangible asset and intellectual capital values. The correlations between these variables are explored both globally and in the European Union using 1,034 observations from 502 F&B companies.

Globally, higher ESG performance corresponds to lower intangible asset values, a trend not observed in the European Union. Further, high ESG performance is associated with a decrease in intellectual capital value, suggesting that internal organisational efforts in this area should be rewarded in terms of short-term value.

This study provides a new understanding of the relationship between ESG performance, intellectual capital, and the F&B industry operating environment, highlighting the complexity and challenges associated with integrating ESG practices.

The Gulf Cooperation Council (GCC) countries have been increasingly investing in their economic and social development in recent years, yet the effectiveness of their spending remains unknown although they have been taking reforms to advance their spending efficiency practices.

The study applies a quantitative approach to analyze panel data using a multiple regression model based on the World Economic Forum (WEF) reports of the global competitiveness index (GCI) from 2009 until 2018.

The results show that policies' strength has a positive and significant influence, while national infrastructure and workforce empowerment have a negative and significant influence over the extent of spending efficiency implementation in the GCC countries.

GCI disclosure assessment criteria changed in 2019 and then stopped in 2020 due to COVID-19. A different version of GCI was published in 2020, which focuses on recovering from the COVID-19 pandemic, and no other issues have been published since then. This represented a barrier to recent data collection.

Practical contribution is the value added by this study to a minimal literature on spending efficiency in the GCC countries. This study’s theoretical contribution to knowledge is the integration of the new institutional sociology (NIS) perspective of institutional theory and the resource slack theory to investigate a set of factors rarely explored in relation to their impact on governmental spending efficiency.

This study provides the following recommendations for policymakers: The GCC government should direct government training bodies and universities (in business majors) to include mandatory spending efficiency subjects to enhance current knowledge. Also, the governmental-related bodies of spending efficiency should make agreements with universities and research centers to improve the diverse R&D aspects of government spending efficiency. Another important recommendation is to enforce the adoption of the GRC concept regarding spending efficiency practices for governmental employees to guide them towards implementing spending efficiency practices.

This study's theoretical contribution to knowledge is the integration of the new institutional sociology (NIS) perspective of institutional theory and the resource slack theory to investigate a set of factors rarely explored in relation to their impact on governmental spending efficiency. Also, the practical contribution is the value added by this study to a minimal literature on spending efficiency in the GCC countries. The research has established empirical evidence to support the findings above.

This study utilizes Bourdieu’s concepts of field, capital and habitus to investigate the networking strategies of Asian and Black knowledge workers in the London Insurance Market. It also examines the factors contributing to the success or failure of these strategies. The trading activities of the London Insurance Market are underpinned by interdependent relations among its participants. It provides an appropriate context for examining the networking strategies adopted by Asian and Black workers to accelerate their careers.

This research employed a qualitative methodology, gathering data from 24 participants through semi-structured interviews. Participants were selected using purposive, convenience, and snowball sampling methods. Thematic analysis was used to analyze data and develop aggregated concepts from the identified themes and subthemes.

The London Insurance Market accords great importance to networking. Interpersonal connections significantly influenced career progression, often overshadowing educational attainments. Asian and Black workers faced systemic nepotism and limited access to influential networks in this field. Participants strategically used their interactions to overcome these challenges and advance their careers. Many believed that their careers had a better chance of progressing through informal networks than through formal channels such as Human Resources. Some participants declined to engage in the commonly accepted networking practices, choosing alternative ways to further their careers.

Findings underscore the need for implementing specific organizational policies to address systemic biases and nepotism, particularly in front-office recruitment. Such policies could include prioritizing merit-based hiring practices and developing targeted initiatives to reduce the underrepresentation of minority ethnic workers in front-office positions. By adopting these measures, organizations can create more equitable career advancement opportunities and leverage the full potential of their diverse workforce.

This study contributes to the existing literature on minority ethnic workers' careers, networking theory and workplace diversity. It provides insights into the networking strategies of Asian and Black workers within the London Insurance Market, revealing that these strategies are dependent on contextual factors. The study also highlights the pervasive practice of nepotism deeply ingrained in the habitus of the London Insurance Market and which acts as a barrier for gaining access to influential networks.

The purpose of this study is to make property price forecasts for the Chinese housing market that has grown rapidly in the last 10 years, which is an important concern for both government and investors.

This study examines Gaussian process regressions with different kernels and basis functions for monthly pre-owned housing price index estimates for ten major Chinese cities from March 2012 to May 2020. The authors do this by using Bayesian optimizations and cross-validation.

The ten price indices from June 2019 to May 2020 are accurately predicted out-of-sample by the established models, which have relative root mean square errors ranging from 0.0458% to 0.3035% and correlation coefficients ranging from 93.9160% to 99.9653%.

The results might be applied separately or in conjunction with other forecasts to develop hypotheses regarding the patterns in the pre-owned residential real estate price index and conduct further policy research.
