Involvement of lenders for PPP highway projects in India starts after the bid award. The post-award development phase of Toll and Annuity PPPs differ significantly in terms of potential risk assumed by lenders. This study aims to assess the impact of the transparency law on the post-award development phase of Toll and Annuity PPPs.

A unique dataset of 469 PPP highway projects implemented in India was used to conduct this empirical study. An OLS regression model was developed to assess the impact of the transparency law on the post-award development phase.

Enacting the transparency law increased the duration of the post-award development phase of Toll projects; however, its impact on Annuity projects was not significant. Moreover, Toll and Annuity projects with a longer post-award development phase had a shorter construction phase. The post-award development phase of the Toll projects was relatively more sensitive to technical, economic and location-specific variables than Annuity projects. Length of road stretch, duration of the concession period and individual income of end-users significantly impacted the duration of this phase of Toll projects.

Transparency law can improve risk mitigation of Toll projects during the post-award development phase.

The impact of transparency law on PPP projects has never been assessed. This study assesses its impact on the two forms of PPPs. It also highlights the determinants of this phase and how they differ for the two forms of PPPs.

Images taken from construction site interiors often suffer from low illumination and poor natural colors, which restrict their application for high-level site management purposes. The state-of-the-art low-light image enhancement method provides promising image enhancement results. However, they generally require a longer execution time to complete the enhancement. This study aims to develop a refined image enhancement approach to improve execution efficiency and performance accuracy.

To develop the refined illumination enhancement algorithm named enhanced illumination quality (EIQ), a quadratic expression was first added to the initial illumination map. Subsequently, an adjusted weight matrix was added to improve the smoothness of the illumination map. A coordinated descent optimization algorithm was then applied to minimize the processing time. Gamma correction was also applied to further enhance the illumination map. Finally, a frame comparing and averaging method was used to identify interior site progress.

The proposed refined approach took around 4.36–4.52 s to achieve the expected results while outperforming the current low-light image enhancement method. EIQ demonstrated a lower lightness-order error and provided higher object resolution in enhanced images. EIQ also has a higher structural similarity index and peak-signal-to-noise ratio, which indicated better image reconstruction performance.

The proposed approach provides an alternative to shorten the execution time, improve equalization of the illumination map and provide a better image reconstruction. The approach could be applied to low-light video enhancement tasks and other dark or poor jobsite images for object detection processes.

Construction material management plays a significant role in achieving successful project delivery of a construction project. However, ineffective material management is a critical issue in the construction industry, especially in developing economies, of which Sri Lanka is not an exception. Therefore, this study aims to focus on exploring the causes of ineffective material management practices in civil engineering construction projects in Sri Lanka and their impact on successful project delivery.

Furthermore, the literature findings were validated through the preliminary survey. Subsequently, a quantitative research approach was adopted to pursue the research aim. Questionnaire responses were obtained from 215 construction professionals in civil engineering projects who were selected using the judgemental and snowball sampling techniques. Collected data were analysed through Statistical Package for the Social Sciences (SPSS) V26 and Microsoft Excel 2016.

Moreover, the study revealed that material price fluctuation, shortage of material in the market, delay in material procurement, inadequate planning and delays in material delivery are the most frequent causes of ineffective material management in civil engineering projects. In addition, it was evidenced that most ineffective material management practices cause both time and cost overruns in civil engineering construction projects. Most respondents emphasized inadequate planning, inadequate qualified and experienced staff, lack of supervision and lack of leadership as the causes for both time and cost overruns.

The study was concluded by proposing strategies for effective material management. Education/training/enlightenment of staff in charge of materials management, use of software like Microsoft Project, Primavera and similar software to eliminate manual errors in material management, and providing clear specifications to suppliers were the most agreed strategies for effective material management in civil engineering construction projects.

Delay and disruption claims involve a complex process that often result in disputes, unnecessary expenses and time loss on construction projects. This study aims to review and synthesize the contributions of previous research undertaken in this area and propose future directions for improving the process of delay and disruption claims.

This study adopted a holistic systematic review of literature following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A total of 230 articles were shortlisted related to delay and disruption claims in construction using Scopus and Web of Science databases.

Six research themes were identified and critically reviewed including delay analysis, disruption analysis, claim management, contract administration, dispute resolution and delay and disruption information and records. The systematic review showed that there is a dearth of research on managing the wide-ranging information required for delay and disruption claims, ensuring the transparency and uniformity in delay and disruption claims’ information and adopting an end-user’s centred research approach for resolving the problems in the process of delay and disruption claims.

Complexities in delay and disruption claims are real-world problems faced by industry practitioners. The findings will help the research community and industry practitioners to prioritize their energies toward information management of delay and disruption claims.

This study contributes to the body of knowledge in delay and disruption claims by identifying the need for conducting more research on its information requirements and management. Subsequently, it provides an insight on the use of modern technologies such as drones, building information modeling, radio frequency identifiers, blockchain, Bigdata and machine learning, as tools for more structured and efficient attainment of required information in a transparent and consistent manner. It also recommends greater use of design science research approach for delay and disruption claims. This will help to ensure delay and disruption claims are the least complex and less dispute-prone process.

The main purpose of this paper is to establish whether trust plays a significant mediating role in the relationship between access to microcredit and survival of young women microenterprises in under-developed financial markets in sub-Saharan Africa. The main focus of this paper is to specifically test whether relational social capital built by young women from homogeneous and heterogeneous groups can be more effective in promoting economic exchange in under-developed financial markets since interpersonal trust has recently been found to harbor group collusion, especially among kins. Overall, the paper distinguishes trust among individuals based on their age, gender and ethnic diversity.

This study used structural equation model to test whether trust significantly mediates the relationship between access to microcredit and survival of young women microenterprises using Analysis of Moments Structures (AMOS) based on recommendations by Hair et al. (2022) and Baron and Kenny (1986).

The findings from this study revealed that trust significantly and positively mediate the relationship between access to microcredit and survival of young women microenterprises in under-developed financial markets in sub-Saharan Africa. Trust developed from relational social capital among young women from homogeneous and heterogeneous groups create a stronger basis for economic exchange in under-developed financial markets.

While this study generates a positive evidence on the impact of access to microcredit on survival of young women microenterprises, the results cannot be over emphasized and generalized because the data were collected from only a single developing country. Future research may extend the current study to include other developing countries to make a more justified comprehensive analysis.

The findings from this study highlights the importance of using a blend of social policy guided by norms combined with formal regulations as an informal contract enforcement mechanism to achieve efficient economic exchange in under-developed financial markets. Relational social capital formed on the basis of informal norms among groups from diverse population can supplement formal laws to enforce contractual obligations in microcredit access, especially among youthful microentrepreneurs, who seems to have stronger relational behaviors than adults. Financial institutions such as banks should use informal contract enforcement system to increase the scope of financial inclusion of young microentrepreneurs, especially in unbanked rural communities in sub-Saharan Africa, Uganda inclusive where formal laws are weak and sometimes not functional. The findings also show that younger people have a stronger relationship behavior than adults. Therefore, policy should create structures that can promote social activities among youth. Governments in sub-Saharan Africa, Uganda inclusive through their respective Ministry of Gender, Labour and Youth Affairs should create youth clubs that can increase interaction and relational social capital among the younger population to derive economic empowerment. sub-Saharan African governments, Uganda inclusive should rely more on social policy based on relational social capital as a missing link to promote and achieve economic development.

This paper provides an evidence on the unique role of age, gender and ethnicity in information sharing and exchange based on social policy in the financial market to limit group collusion. The authors indicate that diversity in relational social capital among young women microentrepreneurs prohibit strategic defaults, which promotes access to microcredit for survival of women micro small and medium enterprises (MSMEs) through socialization. High level of interaction among younger women microentrepreneurs from homogeneous and heterogeneous groups allow them to close the information gap to timely meet borrowing contractual obligations to derive economic benefits. The paper shows that younger women have more trust than older women while searching for economic value through socialization. In fact, social policy can wholly supplement formal policy to promote growth and survival of young women microenterprises, especially in sub-Saharan Africa, Uganda inclusive.

This chapter explores creative drawing mediums in research practice and education, through speculative drawing methods, and the use of temporal mediums such as film, animation, and augmented reality [AR] to move outside entrenched perspectives of communicating towards more inclusive storytelling narratives. Architectural representation mediums provide means of conveying rich layers of information, having evolved through cultural influences and technologies with their origins in Western world views. However, these methods of drawing are limited in how they convey multiple and diverse views or social understandings, ultimately delivering static representations. The student and staff approaches discussed in this chapter demonstrate approaches that recalibrate from a singular, designer-led perspective to one that is multivalent, considering and engaging other stakeholders in the negotiations and conversations of the spaces in our built environments. Through making architectural communication more accessible and inclusive of diverse audiences and voices, alternative world views can be both enabled and facilitated.

This study aims to investigate the quality of disclosure of a cutting-edge reporting tool – integrated reporting (<IR>) – in terms of its effectiveness to report on COVID-19 pandemic information, its ability to provide forward-looking information and risk impact implications, and its quality determinants in challenging times.

Thanks to a content analysis of 247 <IR> for FY20, an integrated reporting disclosure score was developed to assess the disclosure quality provided by the sampled companies. Three research questions were tested through logistic regressions.

Non-financial disclosure activities struggle to provide adequate information in terms of potential future scenarios, risk assessment and forward-looking analyses. However, companies incorporated in “Anglo-Saxon” territories drafted integrated reports of higher quality. More recently, incorporated companies have made a greater effort to measure and report COVID-19 pandemic impacts on environmental, social and governance and business activities, also increasing their risk assessment and mitigation efforts. Concerning the determinants of disclosure quality, leverage, corporate governance structures, country of incorporation and belonging to “high impact” industries all lead to a higher quality of <IR> disclosure.

Examining in detail corporate social responsibility activities and corporate governance integrity is pivotal to orienting strategy towards sustainable trajectories: to do so, corporate reporting and disclosure practices are essential tools. In this context, corporate governance systems that emphasize board diversity are proven, even in disruptive circumstances, to play a crucial role in providing corporate reports of higher quality. High disclosure quality that goes beyond mere financial results is considered to be necessary to remain competitive strategically, socially and environmentally.

Globalization, the ever-increasing worldwide flow of ideas, practices, and material objects resulting in increasing interdependency between people and nations across the globe, has numerous interrelated economic, political, cultural, ideological, environmental, and technological facets.

In an effort to make the elusive and multifaceted concept of globalization more tangible and measurable, different instruments have been developed, usually in the form of “indexes” based on quantitative data. These indexes mainly result in rankings of individual cities as well as whole countries with respect to their supposed level of globalization. Some items of the existing indexes to measure the level of globalization of nation states or cities refer to phenomena that are to some extent visually observable, but many aspects and manifestations of globalization escape these rather crude operationalizations.

Visual approaches to globalization help to enrich and complement the more abstract and mainly quantitatively supported discourses around this multifaceted phenomenon. They may provide valid and unobtrusive ways to assess and understand the impact of culture and cultural exchange in the daily lives of inhabitants of cities around the world and add a unique “localized,” cross-cultural empirical perspective to the many divergent views and discussions about the presumed beneficial or detrimental nature of these processes. An ‘in situ’ visual approach to globalization may help to uncover the “real life” impact and the specific contexts of these processes at different locations. This chapter discusses different options for researching globalization and cultural change in cities.
