The purpose of this paper is to investigate the factors that are significant in contributing to the per capita income growth of countries that are experiencing or have experienced the lower-middle and upper-middle income traps.

The study comprises 85 countries over the period 1960 to 2017 spanning across three income groups: lower-middle, upper-middle and high. A panel data structure was used to run a fixed effect and random effect estimation on three models of income groups. The Hausman specification test, which was used for further statistical fitness, confirmed the appropriateness of fixed effect over the random in explaining the estimation of factor variables.

The results show that unemployment is a pervasive problem that negatively affect countries at all income levels. Foreign direct investment and population of dependents are associated with economic progression of countries that have experienced or are experiencing the lower-middle income trap. Furthermore, rising income inequality and foreign aid assistance are detrimental to countries that have experienced or are experiencing the upper-middle income trap. Moreover, income inequality, disproportionate urban population and rising dependent population are damaging for high income countries that never experienced any of the middle-income traps. Conversely, openness to trade, inflation and exchange rate volatility had limited capacity in explaining growth dynamics.

This study could not incorporate geopolitical, demographic, geographical and other such exogenous factors, which could have episodes of influences on the economic development of countries. These were outside the study's realm of quantitative analysis.

This paper contributes to existing literature by providing an empirical cross-sectional comparative analysis of countries belonging to different income groups. The prevailing literature lacks such a cross-tabulated presentation of factors affecting countries that avoided the middle income trap and those that could not.

In recent years, researchers and practitioners have paid a great deal of attention to the circular economy (CE) due to its potential social and environmental benefits. However, limited attention has been devoted in the literature to studying the barriers to CE implementation in the apparel retail industry in emerging and developing nations besides China. Consequently, the purpose of this paper is to analyse the barriers to implementing CE in the Indian garment retail market.

This exploratory study uses a comprehensive literature analysis to identify the micro-level impediments to CE adoption in India's garment retail industry. The study aims to identify these barriers using a Delphi process, consisting of three stages. The first stage involves literature reviews and expert opinions, while the second and third stages involve survey methods with 14 industry professionals and academics. The use of the two primary data sources allows for triangulation of the data, which improves the validity of the findings and enables broader conclusions to be drawn from the results.

This study indicates that the top three challenges to implementing CE principles in the Indian apparel retail industry are “standards and regulation barriers” (84%), “strategic barriers” (82%) and “supply chain management and technology barriers” (79%). Strategies for overcoming these obstacles include gaining top management support, coordinating supply chain components, training and employee motivation.

This study considers only Indian apparel retail industry, and the practical implications could potentially limit the study to emerging Asian economies.

To the best of the authors’ knowledge, this is the first research of its type to explore CE obstacles at the organizational level in the Indian garment retail business. Thus, it contributes to a greater understanding of the topic and enables practitioners to develop effective policies and business strategies for CE and sustainability.

The purpose of this paper is to investigate in-depth and explain the issues related to the experience of Tunisia, a developing country, in its attempt to move from Euro-Continental rule-based generally accepted accounting principles (GAAPs) to an accounting system adapted to international financial reporting standards (IFRS).

The study is conducted via a qualitative methodology based on a content analysis of primary data from interviews with key actors involved in financial reporting in Tunisia.

Findings reveal that local Tunisian GAAPs, adapted to IFRS in their 1996 version, failed to establish a financial reporting accounting culture and meet public-interest firms’ informational needs. This is mainly related to factors, such as the simplified methods adopted (generally adequate to the identified needs of users of small and medium-sized entity financial statements) and the hybrid aspect of the Tunisian accounting standards due to the co-existence of Euro-Continental and Anglo-Saxon parties. Moreover, the findings show that the lack of political willpower and the absence of updates to changes in IFRS have compromised the proper functioning of standardization and control structures.

The study’s results may interest regulators and policymakers of many developing countries that have not pursued the harmonization of their local GAAPs with IFRS. In addition, findings from the research provide insights into the rough road towards harmonization, the dysfunctions of the latter and delays in developing countries.

The research highlights the complexity for an emerging country with Euro-Continental accounting traditions to move to IFRS.

This paper aims to investigate and provide an objective appraisal of the impact of the COVID-19 outbreak on Islamic and conventional financial institutions and Islamic windows in the Gulf Cooperation Council (GCC) countries.

The panel data techniques are conducted country-wise in each financial institution type: random-effect model, fixed-effect model and Hausman test.

The results of the first phase analysis that extends from 1 January 2020 to 30 October 2020 show that Islamic financial institutions are less exposed to the repercussions of the COVID-19 outbreak than the conventional and Islamic window financial institutions in Bahrain, Oman, Qatar, Saudi Arabia and UAE. Moreover, the Islamic financial institutions in Saudi Arabia and Oman have not been affected by the COVID-19 outbreak. The second phase analysis for the COVID-19 outbreak that extends from 1 November 2020 to 17 March 2021 confirms the disappearance of the negative impact of COVID-19 on Islamic financial institutions in Bahrain and Oman.

The findings present that Islamic banks are not as resilient in the COVID-19 pandemic as in the 2008 financial crisis. It can be suggested that regulatory authorities, financial institutions and other key policymakers in the GCC countries should focus on implementing regulatory reforms related to human capital, innovative products, research and development to further develop individuals, societies and institutions within the framework of Islamic ontology to be more resilient in such crises.

This paper provides a different perspective from existing literature on the pandemics and financial institutions by comparing the stock prices in Islamic and conventional financial institutions and Islamic windows in GCC countries during the COVID-19 pandemic. Therefore, this paper should be considered as a contribution to filling a gap in the literature.

The purpose of this paper is to discuss accounting development in Tunisia, which is a developing North African country little known in the international accounting literature.

Methodologically, this paper is based on an exploratory approach. It uses the descriptive tradition of research by collecting and analyzing numerical and narrative data to identify and describe environmental factors that favor or hamper accounting development in Tunisia.

This paper indicates that Tunisian companies have been applying the Enterprise Accounting System (EAS) since 1996. This system, while keeping with the logic of a chart of accounts, represents a first attempt to harmonize with international accounting standards. Accounting harmonization in Tunisia is meant to support the strategy, launched in the early 1990s, to integrate the country into the globalization process. Accordingly, the EAS has helped to achieve macroeconomic benefits (public interests). However, it does not lead to the desired level of financial transparency (private interests), especially that of large companies. Currently, Tunisian Accounting Standards neither reflect the rapid evolution of business activity nor changes in international accounting standards. This unachieved harmonization has led some listed companies to comply with some International Financial Reporting Standards which are not included in the EAS.

The unachieved harmonization in Tunisia is mainly related to the political system, taxation factors, the legal system, the weak state of corporate governance and governmental control over standardization.

This paper provides insights into the problems of developing countries that harmonize with international standards to achieve public interests. These countries may encounter many difficulties in bringing their accounting standards up to date. These difficulties seem to be associated with environmental specificities. Accordingly, international standardization bodies and developing country regulators should take into account environmental factors which are determinant for the harmonization decision to succeed.

This paper contributes to the existing literature on accounting development in developing countries. It implies that recent accounting development, as it is designed in Tunisia, is better suited to the needs of small businesses. Large companies would be compelled to complement local generally accepted accounting principles by standards they choose, voluntarily, among international standards.

The UK construction industry produces up to one third of all waste to landfill. This study aims to identify specific project practices impeding the reduction of waste in construction projects as well as uncovering potential waste solutions throughout the project delivery process. The rationale being that for such a drastic reduction in waste to landfill, holistic and extensive measures would be required.

A two‐way methodological approach was used. This comprised qualitative unstructured interviews and a quantitative questionnaire survey of three major stakeholders in the UK construction industry: clients, architects and contractors.

Design factors remain the major cause of impediments to waste reduction to landfill. Critical impediments include clients making waste prevention a top priority in projects, overly complex designs, waste taking a low priority compared to project time and costs, lack of concerns by designers for buildability, among others. Critical solutions include early supply chain involvement in design process, choosing materials for their durability, early communication of design changes to all parties, longer project programmes and better lead times, among others.

In all, the target of halving construction waste to landfill based on the 2008 benchmark is achievable but would require construction companies to take it upon themselves to implement the proposed solutions suggested by this study.

The value of this research is to provide UK construction companies with solutions to reduce waste and aid the reaching of the landfill target, as landfill is decreasing as a solution to waste. In addition the cost savings on reducing waste could be crucial for companies in this current economic climate.

The purpose of this paper is to investigate the performance of natural Jordanian zeolite tuff to remove ammonia from aqueous solutions using a laboratory batch method and fixed-bed column apparatus. Equilibrium data were fitted to Langmuir and Freundlich models.

Column experiments were conducted in packed bed column. The used apparatus consisted of a bench-mounted glass column of 2.5 cm inside diameter and 100 cm height (column volume = 490 cm3). The column was packed with a certain amount of zeolite to give the desired bed height. The feeding solution was supplied from a 30 liter plastic container at the beginning of each experiment and fed to the column down-flow through a glass flow meter having a working range of 10-280ml/min.

Ammonium ion exchange by natural Jordanian zeolite data were fitted by Langmuir and Freundlich isotherms. Continuous sorption of ammonium ions by natural Jordanian zeolite tuff has proven to be effective in decreasing concentrations ranging from 15-50 mg NH₄-N/L down to levels below 1 mg/l. Breakthrough time increased by increasing the bed depth as well as decreasing zeolite particle size, solution flow-rate, initial NH₄+ concentration and pH. Sorption of ammonium by the zeolite under the tested conditions gave the sorption capacity of 28 mg NH₄-N/L at 20°C, and 32 mg NH₄-N/L at 30°C.

This research investigates the performance of natural Jordanian zeolite tuff to remove ammonia from aqueous solutions using a laboratory batch method and fixed-bed column apparatus. The equilibrium data of the sorption of Ammonia were plotted by using the Langmuir and Freundlich isotherms, then the experimental data were compared to the predictions of the above equilibrium isotherm models. It is clear that the NH₄+ ion exchange data fitted better with Langmuir isotherm than with Freundlich model and gave an adequate correlation coefficient value.

The purpose of the study is to examine the sliding wear performance of plasma transfer arc (PTA) deposited and laser surface melted (LSM) Mo modified Stellite 12 hardfacings under high contact stresses (i.e. >20 GPa).

For this purpose, after structural characterization, sliding wear tests have been conducted using sphero-conical diamond indenter as the counterface with different normal loads. The wear tracks formed on the hardfacings were examined by atomic force microscopy and scanning electron microscopy.

Both hardfacings showed severe wear (at high contact stress levels ranging from 24 to 41 GPa), which progressed by plastic deformation, although the wear resistance of LSMed hardfacings was better than the PTA hardfacings by a factor of two due to its near surface microstructure characterized as carbide-rich zone.

Sliding wear characterization of a promising 10 Wt.% Mo modified version of commercial Stellite 12 hardfacings (as reported previously by authors) was done in as PTA and LSMed states using nanomechanical test system. To the best of authors’ knowledge, no report is available in the open literature on such hardfacings under these testing conditions.
