Purpose: This paper aims to examine a research model that links knowledge sharing enablers, processes and outcome dimensions in law enforcement in the United Arab Emirates (UAE). It attempts to examine the impact of knowledge self-efficacy and top management support on knowledge donating and collecting. It also attempts to examine the effect of these two aspects of knowledge sharing on firm innovation capability.Design/methodology/approach: This study used a quantitative approach, with data collected by questionnaire from 685 police officers in a law enforcement agency in the UAE.Findings: Knowledge self-efficacy and top management support have a positive impact on knowledge donating and collecting. Only knowledge collecting, however, had a positive effect on firm innovation capability.Research limitations/implications: The study has significant academic and practical implications. It supports a previous research model that links enablers, processes and outcomes of knowledge sharing, and confirms them in the context of law enforcement in the UAE. It could also help law enforcement agencies to promote a knowledge sharing culture to support innovation in the UAE.Originality/value: The research model is likely to be particularly valuable in knowledge-intensive organizations such as the law enforcement sector. Knowledge sharing is often overlooked by organizations in the UAE because there has to date been little research in this field.

The revitalisation of the global economy after the Covid-19 era presents environmental geotechnics with the opportunity to reinforce the need for a change in paradigm towards a green, circular economy and to promote aggressively the use and development of sustainable technologies and management practices. This paper aims to assist in this effort by concentrating on several thematic areas where sustainability solutions and future improvements are sought. These include the re-entry of construction and demolition of wastes, excavated materials, industrial wastes and marine sediments into the production cycle and the reuse of existing foundations. Despite the recent trend in advanced countries towards recycling and waste-to-energy thermal treatment, landfills still constitute the most common municipal solid waste management practice, especially in low-and-middle-income countries, and technological solutions to improve their environmental footprint are hereby presented. At the same time, remediation solutions are required to address the multitude of contaminated sites worldwide. Advanced developments that incorporate environmental, economic and social dimensions are expounded by the authors, together with sustainable ground improvement solutions for infrastructure projects conducted in soft and weak soils. The topic of thermo-active geostructures concludes this paper, where, apart from their infrastructure utility, these structures have the potential to contribute to the renewable energy source.

Methane (CH₄) emissions from the waste industry in the U.S.A. and the European Union (EU) have decreased by over 38% from 1990 to 2021. The success in CH₄ emission reduction in the U.S.A. is attributable to two main reasons. Firstly, the increase in the recycling and composting share to 32% of managed waste, thus removing decomposable material from landfills, and secondly, the implementation of methane capture and utilization programs, which have reduced the CH₄ released into the atmosphere from 1990 to 2022 by over 60%. By 2022, the EU had reduced landfilling to 23% of the total waste, with waste-to-energy and composting more than double that of their U.S. counterparts, and recycling alone attaining a share of 30%. The EU’s success has been the result of aggressive European legislation requiring biodegradable MSW going to landfills to be reduced by 2035 to 10% of that in 1995, and 65% of packaging waste to be retrieved and recycled by 2025. In terms of N₂O emissions, in the EU there was a decrease from wastewater processes from 1990 to 2021, but an overall increase due to waste-to-energy operations, whereas in the U.S.A., both wastewater treatment and solid waste incineration appear to contribute to N₂O emissions.

Purpose: The purpose of this paper is to propose a novel framework and a systematic group of methodologies for constructing a computer-based design system that could support homebuyers’ participation in the design of their dwellings in the UAE housing market. Design/methodology/approach: In order to construct the framework, the paper first presents an overview of current applications of mass customization in the realm of architecture, with focus on successful models in North America. Second, the authors analyze the housing market in the UAE, focusing on challenges and opportunities. This leads to structuring the proposed advanced configuration system based on ideas of technology transfer from other industries. Finally, the profile matching model emerges as a logical consequence of the proposed advanced configuration model. Findings: The analysis of the UAE real estate market reveals interesting growth that encourages application of cutting-edge technologies not just in construction methods, but also in new modes of integrating homebuyers in a participatory dialogue for a sustainable outcome. Within the study, the authors call for new roles, digital design and information management technologies can play to enable participatory design. Additionally, the authors propose a new business model that requires extensive studies of the market, and buyers/developers behavior. Research limitations/implications: The framework proposed in this paper is considered generic and flexible. It raises various issues regarding its applicability, specifically with regard to market readiness. One of the first challenges is possibility of gathering precise data about the housing market in UAE to measure its size and readiness. Additionally, there are also challenges in finding focused developers and builders that are ready to engage in a dialog toward adopting mass customization as a business model. Practical implications: Mass customization implies adopting a flexible, technology-oriented business model. This raises multiple implications: developing configuration systems, the number of design alternatives has to be limited to three or four options in order to avoid additional overhead cost; implementing a digital platform for customization requires investment in tools, systems, and accordingly operators. Higher cost associated with mass customization occur both in sales and customer interaction as well as in manufacturing; and conducting a financial framework for implementing the proposed system requires intensive market studies which is considered challenging. Originality/value: The proposed framework derives its novelty by analyzing mass customization theories, technological enablers, various research endeavors in housing, and currently adopted online marketing and sales strategies in the UAE housing market. The implementation of the proposed system would represent a mile stone in the UAE housing market, being capable of redefining the process through which homebuyers, architect, and housing and developers communicate.

Purpose: The purpose of this study is to investigate the associations between dimensions related to pre-job training and the effectiveness of training on graduate employability through direct and indirect pathways. Design/methodology/approach: Using data from 309 SANAD trainees in the UAE, this research also contextualizes these dynamics within the broader framework of sustainable development, particularly aligning with Sustainable Development Goal 12 (SDG 12), which promotes responsible consumption and production. The study employed a deductive, quantitative approach grounded in human capital theory. Findings: Findings demonstrate that training effectiveness partially mediates the relationship between pre-job training factors and employability. Moreover, trainees’ prior expectations significantly moderate this relationship. By fostering employability and aligning training outcomes with national sustainability agendas, particularly SDG 12, the SANAD training program contributes to reducing inefficiencies and resource misallocations in the labor market. Originality/value: Future research may explore how sustainability-aligned training content enhances long-term employability outcomes. This paper contributes to both employability literature and the intersection of training effectiveness with sustainability frameworks.
