The European Union (EU) is providing a wide range of instruments to its members in implementing a green, resilient economy. These instruments are not designed only for governments and state representatives but also for small businesses and entrepreneurs. The ability of those two-targeted audiences to understand and adopt these instruments, as well as their way to react and profit from the EU-stated drives, determines one’s country capacity to absorb European funding and create economic growth. The present chapter proposes a presentation of the new European model for economic growth and of the advantages proposed with the European Green Deal, the European proposal to the world for a resilient, adaptable, and environmentally friendly economy.

There is growing recognition that effective project control systems (PCS) are critical to the success of projects. The relationship between the individual elements of PCS and successfully achieving project objectives has yet to be explored. This research investigates the enablers and barriers that influence the elements of PCS success and drive project objectives.

This study adopts a mixed approach of descriptive analysis and regression models to explore the impact of six PCS elements on project outcomes. Petroleum and chemical projects in Saudi Arabia were selected as a case study to validate the research model.

Data from a survey of 400 project managers in Saudi’s petroleum and chemical industry reveal that successful PCS are the key to achieving all project outcomes, but they are particularly critical for meeting project cost objectives. Project Governance was identified as the most important of the six PCS elements for meeting project objectives. A lack of standard processes emerged as the most significant barrier to achieving effective project governance, while having skilled and experienced project team members was the most significant enabler for implementing earned value.

The study offers a direction for implementing and developing PCS as a strategic tool and focuses on the PCS elements that can improve project outcomes.

This research contributes to project management knowledge and differs from previous attempts in two ways. Firstly, it investigates the elements of PCS that are critical to achieving project scope, schedule and cost objectives; secondly, enablers and barriers of PCS success are examined to see how they influence each element independently.

Community detection is a key factor in analyzing the structural features of complex networks. However, traditional dynamic community detection methods often fail to effectively solve the problems of deep network information loss and computational complexity in hyperbolic space. To address this challenge, a hyperbolic space-based dynamic graph neural network community detection model (HSDCDM) is proposed.

HSDCDM first projects the node features into the hyperbolic space and then utilizes the hyperbolic graph convolution module on the Poincaré and Lorentz models to realize feature fusion and information transfer. In addition, the parallel optimized temporal memory module ensures fast and accurate capture of time domain information over extended periods. Finally, the community clustering module divides the community structure by combining the node characteristics of the space domain and the time domain. To evaluate the performance of HSDCDM, experiments are conducted on both artificial and real datasets.

Experimental results on complex networks demonstrate that HSDCDM significantly enhances the quality of community detection in hierarchical networks. It shows an average improvement of 7.29% in NMI and a 9.07% increase in ARI across datasets compared to traditional methods. For complex networks with non-Euclidean geometric structures, the HSDCDM model incorporating hyperbolic geometry can better handle the discontinuity of the metric space, provides a more compact embedding that preserves the data structure, and offers advantages over methods based on Euclidean geometry methods.

This model aggregates the potential information of nodes in space through manifold-preserving distribution mapping and hyperbolic graph topology modules. Moreover, it optimizes the Simple Recurrent Unit (SRU) on the hyperbolic space Lorentz model to effectively extract time series data in hyperbolic space, thereby enhancing computing efficiency by eliminating the reliance on tangent space.

The case was devised using secondary sources of data collection from annual reports, sustainability reports and the Hindustan Petroleum Corporation Limited (HPCL) website. These documents provided insights into the HPCL’s sustainability initiatives, financial performance and disclosure practices. Other data were obtained through the websites of the relevant businesses/sectors.

In March 2022, Pushp Kumar Joshi, chairman and managing director of HPCL, contemplates the oil giant’s sustainability strategy amid challenges. Despite a 38% revenue increase in financial year 2021–2022, profits dropped because of reduced refinery capacity. HPCL, a major player in India’s oil and gas industry, recognized the need to align with climate goals and changing consumer expectations. Joshi emphasized stakeholder engagement, carbon mitigation, technology adoption and transparent environmental, social and governance (ESG) reporting. A materiality assessment highlighted key issues like gender diversity, air quality and the low-carbon transition. Joshi grapples with balancing profitability and sustainability amid stakeholder pressure and market fluctuations, seeking advice from the sustainability team for the future.

This can potentially be a case study for a business management course, particularly focusing on sustainability, corporate social responsibility and strategic decision-making. It could be used at both the undergraduate and graduate levels in courses related to business administration, sustainability management, corporate strategy, environmental management or stakeholder engagement. The case could be analyzed to discuss the challenges and opportunities faced by a company like HPCL in balancing profitability and sustainability, developing effective sustainability strategies, integrating ESG considerations and managing stakeholder expectations.

This study aims to synthesize two different benzoxazines (Bz) monomers using bio-based and petroleum-based primary amines, respectively, and they have been compared to study their thermal and mechanical performances.

A bio-based bisphenol, Divanillin (DiVa), was formed by reacting two moles of vanillin with one mole of ethylenediamine (EDA) which was then reacted firstly with paraformaldehyde and EDA to form the benzoxazine DiVa-EDA-Bz, and secondly with paraformaldehyde and furfuryl amine (FFA) to form the benzoxazine DiVa-FFA-Bz. The molecular structure and thermal properties of the benzoxazines were characterized by fourier transform infrared spectroscopy and nuclear magnetic resonance (1H,13C) spectroscopies, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), respectively. The benzoxazines were further coated on mild steel panels to evaluate their mechanical properties and chemical resistance.

The DSC results of DiVa-FFA-Bz showed two exothermic peaks related to crosslinking compared to the one in DiVa-EDA-Bz. The DiVa-FFA-Bz also showed a higher heat of polymerization than DiVa-EDA-Bz. The TGA results showed that DiVa-FFA-Bz exhibited higher thermal stability with a residual char of 54.10% than 43.24% for DiVa-EDA-Bz. The chemical resistance test results showed that DiVa-FFA-Bz showed better chemical resistance and mechanical properties due to its higher crosslinking density.

This study shows the use of bio-based materials, vanillin and FFA, for synthesizing a benzoxazine resin and its application at high temperatures.

This paper explores the relevant fire code requirements and outlines the development of an evaluation tool based on these codes to evaluate fire safety measures in dining properties.

Existing literature was examined to identify the combustible materials, fire causes and factors making these properties prone to fire incidents. An evaluation method, based on code regulations, for ensuring fire safety in dining properties was then developed and tested on a specific dining facility to validate its practicality.

Forty requirements, grouped into seven categories, were identified for ensuring fire safety in dining properties. The case study exposed multiple violations of fire safety, leading to corrective measures for enhancing the fire safety status of the building.

This study introduced a methodical approach for raising awareness, among property managers of dining properties, about fire incidences and their consequences. It presents an evaluation tool for assessing the compliance level with fire codes and standards.

Dining properties are facilities that offer both dine-in and take-out food services. Given the increasing number of fire incidents in dining properties worldwide, there is a substantial demand for a process to audit the adherence to fire safety codes in these properties. This study presents a systematic approach to increase public knowledge of fire events and their effects in dining properties.

Situated as a semi-autonomous entity in northern Iraq, the Kurdistan Region boasts abundant natural gas resources, attracting interest from Russian firms and Turkish stakeholders. However, Iran’s influence in Iraq and the wider region poses a regional threat to the Kurdistan Region’s natural resources. This chapter meticulously examines the oil and gas blocks within the Kurdistan Region amidst the backdrop of transformative global energy market shifts, including the impacts of the COVID-19 pandemic and the Russian–Ukrainian conflict. Through this lens, it seeks to delineate the Kurdistan Region’s political and economic positioning within the evolving regional order.

Oil and gas sector has more disruptions regarding its logistics management than any other industry. It is critical to understand which external security threats disrupt the oil and gas supply chain (OGSC). Recently, the time interval between these disruptions became frequent. the purpose of this paper is to identify key logistics elements that lead to such disruptions which would greatly benefit the oil and gas industry in developing more effective mitigation measures and resilient practices in the future.

This research develops the theoretical framework through a critical review of all theories related to resilience, logistics disruptions and mitigation methods in the oil and gas industry. Afterward, semi-structured interviews were conducted with executives in the Egyptian oil and gas industry to develop a conceptual framework. Finally, an empirical study was conducted through questionnaires with managers in the Egyptian oil and gas sector to develop the applied framework.

This research revealed that achieving an elevated level of flexibility, redundancy, visibility and collaboration in the Egyptian OGSC will significantly increase the level of resilience in the sector and consequently help in mitigating probable logistics disruptions.

This research contributes to academia by providing a conceptual framework for the most common logistics disruptions in the Egyptian OGSC and providing practitioners with the best resilience practices that are feasible and effective in mitigating logistics disruptions.

Previous research studied disruptions in OGSC from different perspectives: economic, social, political, technical, safety, legal and environmental perspectives, but no research highlighted the logistics perspective in the Egyptian context, to the best of the authors’ knowledge.

This study aims to explore the possibilities for regional (intra and inter) trade between Central Asia and South Asia (CASA) by examining several frameworks that impact the economic integration of these regions.

The study uses five indices, specifically the export diversification index, export survival rates, export sophistication, revealed comparative advantage and intra-industry trade index in South and Central Asia, from 2005 to 2021.

The findings show a twofold increase in the potential trade value between the two regions compared to the actual level. The intra-regional trade in Central Asia accounts for less than 5% of trade with all countries, whereas the intra-regional trade in South Asia accounts for 1.5%, and the inter-regional trade accounts for between 0.2 and 4% of total trade to all destinations. The intensity of trade measurements shows that inter-regional trade flows are modest because they make up a relatively small percentage of the entire trade volume, which includes all destinations, ranging from 0.2 to 4 %.

These findings have a significant impact on the successful implementation of trading-related measures, initiatives and institutional mechanisms for encouraging improved trade between and within both regions.

Export diversification initiatives aim to provide favourable outcomes for all parties involved, focusing on expanding the range of goods and services exchanged. CASA countries with higher diversification have shown more favourable outcomes than those relying on a restricted range of products. The authors expect policies promoting a broader array of exports to boost market shares, while maintaining a narrow focus may hinder new export prospects. In addition, regional value chains and policy initiatives promoting trade and investment could lead to increased value additions to exports, technological transfers and job creation.

The study emphasises the significance of trade-related policies, programmes and institutional mechanisms in promoting trade between CASA. It emphasises the need for policies that support investment and trade, adopt new requirements of the Agreement on Trade Facilitation and promote diversity and latency.

Based on economic analysis, the study offers practical insights and strategies for businesses in the CASA regions. It also provides analytical tools for academics and decision makers, as well as policy and programme recommendations for government agencies, development partners, researchers and individuals interested in trade dynamics in these regions.
