The purpose of this paper is to analyze the rationales for, the trends and the impacts of innovations in the public management system of the United Arab Emirates (UAE).

This study has adopted an interpretative and exploratory approach. To this end, extensive reviews have been made of government documents, reports of international organizations and relevant academic research articles.

The findings show that the UAE Government has embarked on a massive innovation program to bring dynamism and to feed the requirements of the UAE Vision 2021. As pressured by both external and internal forces, the directions of innovations in the UAE public management system correspond to the global trends. The results of innovations are positive in terms of the enhancement of efficiency, effectiveness, citizens’ satisfaction and citizens’ trust in public services.

This paper links theoretical insights from different sources to analyze the dynamics of public management innovations in the UAE which will be helpful for further comprehensive empirical research in the future.

This paper aims to provide a systematic review of the academic literature on the determinants, processes and impacts of indigenous entrepreneurship (IE), highlights its contribution to current knowledge and identifies research gaps to guide future research.

Databases used in this study included Scopus, ABI, Business Source Complete, ProQuest and Emerald Insight. In total, 84 articles were included in the review.

The findings revealed that 33 studies were qualitative, 12 used a survey-based approach, 25 were conceptual and 14 used mixed approaches. The focus on theory-building research underlines the fact that more theory-testing research is needed in the future. In total, 38 studies were conducted in developed countries and 43 in developing countries. The findings indicated that IE was driven by many determinants such as family and clan ties, patriarchy and social stratification, government support and conducive entrepreneurial ecosystems. Processes related to policies, IE development programs, partnerships, expenditure mechanisms, equitable distribution of benefits and resource mobilization. The outcomes of IE included economic development, sustainability, increased indigenous economic participation, enhanced quality of life, self-determination and preserving cultural heritage.

The current paper has some limitations. Firstly, it focuses only on academic journals and excludes conferences, books and working papers. Secondly, it includes only English language academic articles. However, while the current systematic literature review (SLR) has these limitations, it presents a thorough view of the determinants, processes and impacts of IE. Future studies may consider other sources beyond academic journals and also include non-English publications, and this approach may identify interesting areas for future research.

Existing reviews of IE take a narrow perspective and fail to present a comprehensive view of the IE phenomenon. The current study aims to fill this gap in the literature and provides a SLR pertaining to IE’s determinants, processes and impacts. The review is both timely and relevant because it identifies gaps and serves as a springboard to guide future research.

The purpose of this paper is to analyze the rationale for using social engineering as a tool to impact the nationalization of workforce in the United Arab Emirates (UAE).

Interpretative and exploratory approaches have been employed for this research. Accordingly, the study has extensively reviewed government documents, reports of international organizations and relevant academic literature, including journal articles, conference papers and unpublished dissertations.

The findings show that the UAE Government has initiated multiple policies and programs to enhance participation of indigenous Emiratis in the burgeoning labor market which has been hitherto dominated by the expatriates. However, while the Emiratization programs are on the verge of fulfilling the targets in the public sector job market, significant gaps exist between the targets and accomplishments in the private sector, causing policy concern.

This paper links theoretical insights from the social engineering model used in the social sciences research to analyze the dynamics of workforce nationalization. The study will be helpful to inform further empirical research in this area.

Like many developing countries, Bangladesh has been experimenting with decentralization for a long period. However, despite numerous efforts undertaken over the years, decentralized governance remains elusive in Bangladesh. Drawing on historical and contemporary evidence, this paper analyzes the factors underlying the non‐functioning of decentralization in Bangladesh.

The purpose of this paper is to explore and analyse the factors influencing the relative success and failure of new public management (NPM) initiatives in the developing world, with particular reference to Singapore and Bangladesh.

Secondary materials have been extensively used, interpreted and reinterpreted to substantiate the arguments. The analysis has been confined to two countries. However, the experiences of NPM initiatives of other countries have also been analysed to strengthen the arguments.

There are some critical factors such as the advanced level of economic development, the existence of a formal market economy, the rule of law, the advanced level of administrative infrastructure and state efficiency for the success of NPM‐oriented reforms. To a large extent, Singapore fulfills these conditions. Bangladesh is lagging behind these conditions, and has achieved very little in NPM initiatives. The findings also indicate that there is still a greater role of the state in socio‐economic transformation in general and implementation of market‐oriented reforms in particular.

The Singapore case offers ample lessons for low‐income developing countries such as Bangladesh who are struggling with their administrative reforms.

The value of the paper lies in clearly delineating the factors of success and failure and relating these to concrete cases on a comparative basis. More importantly, analyses of the Bangladesh case could be of immense value to state decision makers of Bangladesh and countries with similar socio‐economic and political standings.

Considering sustainability and resilience together is crucial in food supply chain (FSC) management, as it ensures a balanced approach that meets environmental, economic and social needs while maintaining the system's capacity to withstand disruptions. Towards this, a multi-objective optimisation model is proposed in this study to create an integrated sustainable and resilient FSC. The proposed model employs four objective functions – each representing a dimension of sustainability and one for resilience and utilises an augmented ϵ-constraint method for solving. The findings highlight the interplay between sustainability aspects and resilience, illustrating that overemphasis on any single dimension can adversely affect others. Further, the proposed model is applied to the case of Indian mango pulp supply chain and several inferences are derived. The proposed model would assist decision-makers in making a well-balanced choice based on sustainability and resilience considerations.

Natural convection in finite enclosures is a common phenomenon in various thermal applications. To provide the thermal design guidelines, this study aims to numerically explore the potential of using internal baffles and nanofluids to either enhance or suppress heat transport in a vertical annulus. Furthermore, the annular-shaped enclosure is filled with aqueous-silver nanofluid and the effects of five distinct nanoparticle shapes are examined. In addition, the influence of baffle design parameters, including baffle position, thickness and length, is thoroughly analyzed.

The finite difference method is used in conjunction with the alternating direction implicit and successive line over relaxation techniques to solve nonlinear and coupled partial differential equations. The single phase model is used for nanofluid which is considered as a homogeneous fluid with improved thermal properties. The independence tests are carried out for assessing the sufficiency of grid size and time step for obtaining results accurately.

The baffle dimension parameters and nanoparticle shape exhibit significant impact on the convective flow and heat transfer characteristics, leading to the following results: sphere- and blade-shaped nanoparticles demonstrate around 30% enhancement in the heat transport capability compared with platelet-shaped nanoparticles, which exhibit the least. When considering the baffle design parameter, either a decrease in the baffle length and thickness or an increase in baffle height leads to an improvement in heat transport rate. Consequently, a threefold increase in baffle height yields a 40% improvement in thermal performance.

Understanding the impact of nanoparticle shapes and baffle design parameters on flow and thermal behavior will enable engineers to provide valuable insight on thermal management and overall system efficiency. Therefore, the current work focuses on exploring buoyant nanofluid flow and thermal mechanism in a baffled annular-shaped enclosure. Specifically, an internal baffle that exhibits conductive heat transfer through it is considered, and the impact of baffle dimensions (thickness, length and position) on the fluid flow behavior and thermal characteristics is investigated. In addition, the current study also addresses the influence of five distinct nanoparticle shapes (e.g. spherical, cylindrical, platelet, blade and brick) on the flow and thermal behavior in the baffled annular geometry. In addition to deepening the understanding of nanofluid behavior in a baffled vertical annulus, the current study contributes to the ongoing advancements in thermal applications by providing certain guidelines to design application-specific enclosures.
