The authors empirically examined the theoretically recognized industrial linkages between manufacturing and services from the trade perspective. In particular, they confirmed the trade effect of manufacturing on services, given that global value chain fragmentation pervades and splits manufacturing and services segments separately in developed and developing countries.

Based on observations of 47 countries with manufacturing and service trade data from 1990 to 2020 and with gravity model specification, the authors primarily used the Poisson pseudo-maximum likelihood (PPML) estimation with multiple levels of fixed effects. Considering that many zero values are included in the dependent variable and potential endogeneity, other methods such as Tobit regression, Heckman estimation and two-stage least squares estimation (2SLS) are used. Subsample estimation also supplemented the empirical research.

The results showed that manufacturing trade is a stepping-stone rather than an obstacle to service trade. This finding exhibited significant robustness under different model specifications, instrumental variable estimation and subsample checks. Moreover, in contrast to the north–north country ties, manufacturing trade between northern and southern countries has played a prominent stepping-stone role; meanwhile, manufacturing trade among core–peripheral countries has a considerably more significant impact than the outcomes of core–core and peripheral–peripheral countries.

The authors provided direct clarification and revealed that trade in manufacturing remains the demand basis for service trade. As trade in manufacturing and services are typical phenomena of transnational production linkages, the authors suggested exploring the underlying role of global value chain (GVC) fragmentation and the offset and even barrier effect of biased institutional arrangements on GVC fragmentation.

Commercial and Islamic banks are important players in the UAE financial market. However, little is known about their financial distress because these financial institutions usually resolve financial distress within their own organisations, which means that outsiders cannot explicitly observe distress. The purpose of the research is therefore to identify the main drivers of financial institutions' financial distress.

The paper estimates a probability distress prediction model using the BankScope Database and the annual reports of UAE financial institutions submitted to UAE Security Exchange Authority. The paper also analyses the impact of macroeconomic information for forecasting financial institutions' financial distress.

The fundamentals of financial institutions in terms of cost income ratio, equity to total assets, total asset growth and ratio of loan loss reserve to gross loans (all these variables with a lag of one year) positively impacted the probability of financial distress in the next year. Recent findings for emerging economies have cast some doubt on the usefulness of macroeconomic information for financial institutions' risk assessment. Similar results are found for UAE financial institutions in predicting the probability of financial distress.

This is the first study to provide empirical evidence on the drivers of financial distress of commercial and Islamic banks in UAE during 2000‐2008, and to examine the extent of the financial distress that can be can be attributed to internal bank‐specific fundamental factors and external factors in the economy.

This study has the following aims. First, it tries to clarify the relationship between global value chain (GVC) participation and innovation performance. To date, research generated mixed results. Secondly, it explores a novel way of investigating GVC participation by focusing on the sectoral level in which organizations operate using the concept of GVC embeddedness, which has not been investigated to date.

Data from two sources are combined. The European Company Survey of 2019 provides data about the innovation performance of organizations. These data include measures about production and process. At the sectoral level, these company-level data are combined with data from the Trade in Value Added from the Organization for Economic Cooperation and Development. In total, more than 20,000 companies were investigated, which operate in 15 sectors in 28 countries. This three-level structure is analysed using multilevel ordered probit analyses.

The results show that forward participation and backward participation at the sectoral level are positively related to product innovation and process innovation. The probability of not being engaged in innovation is reduced through GVC embeddedness. And, the probability of generating incremental and radical innovations (both regarding products and processes) increases if GVC participating at the sectoral level is higher.

This study is the first to relate sectoral GVC embeddedness to the innovation performance of organizations.

This paper aims to contribute to the political connection literature by investigating the impact of political connection on banks’ profitability in Bahrain.

Exploiting the unique natural experiment of the 2017 Qatar blockade crisis, this study uses primary data of political connection. The study uses the difference-in-difference (DID) methodology to investigate the effect of political connections on banks’ profitability.

The main finding is that political connections have a positive effect on bank profitability in Bahrain. The paper finds that the ongoing GCC crisis has had a negative effect on the banking sector of Bahrain. During the Qatar blockade crisis, politically connected banks suffered more than their non-connected counterparts.

The result suggests that the Qatar blockade crisis has had a notable effect on the banking system throughout the region, including both the boycotting countries as well as Qatar. In the banking sector, politically connected banks are the most harmed by the crisis. Investors can enhance their hedging and investment decisions by exploiting knowledge of how political connections affected bank profitability during the Qatar diplomatic crisis and how that effect can be transmitted from one market to another. In addition, regulators could use insights about the association between political connections and profitability in Bahrain to undertake strategies to increase banks’ profitability and mitigate the transmission effect of a crisis by ensuring adequate regulation and supervision.

This paper offers four novel contributions to political connection literature as follows: Firstly, the study fills in an important gap in the literature as it is the first attempt to quantify the impact of political connections on bank performance in Bahrain. To the best of the authors’ knowledge, the role of political factors in Bahrain has not been studied about the banking system. Secondly, the study depends on primary data about political connections collected manually from various sources. Thirdly, this is the first study to investigate the effect of the Qatar blockade on the banking sector. Lastly, the evidence suggests that politically connected banks are more profitable than banks that lack political connections. However, the Qatar blockade crisis resulted in a sharp decrease in bank profitability, suggesting that the crisis significantly harmed the banking sector in Bahrain.

This study aims to investigate the differences in spatial ability between students with a math learning disability and their normal peers.

To investigate these differences two groups, (60 students with a math learning disability) and (60 normal students) from fifth grade with a mean age (10.6 years) were administered with spatial ability test along with an IQ test. Students with a math learning disability were chosen using measures of the following: math learning disability questionnaire developed from learning disability evaluation scale – renormed second edition (LDES-R²) (McCarney and Arthaud, 2007) and the Quick Neurological Screening Test (Mutti et al., 2012), in addition to their marks in formal math tests in school.

Comparison between the two groups in four aspects of spatial ability resulted in obvious differences in each aspect of spatial ability (spatial relations, mental rotation, spatial visualization and spatial orientation); these differences were clear, especially in mental rotation and spatial visualization.

This paper contributes to gain more insights into the characteristics of pupils with a math learning disability, the nature of spatial abilities and its effect on a math learning disability. Moreover, the results suggest spatial ability to be an important diagnose factor to distinguish and identify students with a math learning disability, and that spatial ability is strongly relevant to math achievement. The results have significant implications for success in the science, technology, engineering and mathematics domain.

This paper aims to develop and validate a strategy for reducing construction waste (CW) generated during the design process (DP) in architectural design firms (ADFs) in Egypt.

Qualitative and quantitative research methodology was designed to accomplish four objectives. The literature review investigated DP, CW, waste management (WM) and WM strategies (WMS). Three case studies were analysed to investigate the role of WMS towards reducing CW during DP. A survey questionnaire was conducted with a representative sample of ADFs in Egypt to assess their perception and application of WMS during DP. Lastly, a strategy was developed and validated to reduce CW generated during DP.

Through literature review, the research identified the highest 40 causes of CW during the DP and classified them into 13 categories. Despite early promotion of WMS to reduce CW at its source, Egypt and other countries with similar construction market characteristics lack laws and regulations to address CW during the DP, with current codes primarily focusing on post-occurrence issues. In addition, analysis of three case studies showed that CW was reduced by adopting WMS during the DP. Findings of data analysis revealed that ADFs have an average knowledge of WMS and a low awareness of Egyptian laws and WMS during DP. “Prefabrication” was the highest-ranked strategy for CW reduction during DP. Several challenges hamper the implementation of WMS. The “preparation and briefing” was ranked the most common design stage where CW causes occur, while “waiting” was ranked the most common form of CW. These findings informed the research outcome and helped in the development of the proposed strategy.

The proposed strategy was developed taking into account the results of the survey questionnaire which was conducted in ADFs in Egypt where the authors reside, and such a strategy is needed. However, it could be applied in other countries that share the same characteristics of the architectural DP as well as the causes of CW and WMS implementation challenges.

This research presents a practical strategy to reduce CW generated during the DP. It was based on the findings of literature review, case studies and survey questionnaire. The strategy was explained in a workable way to include the required activities; tools and techniques; involved personnel and needed resources. The strategy was validated by a representative sample of ADFs in Egypt to ensure its practicability and viability for implementation towards developing a sustainable built environment. The practical application of the strategy will have long-term and short-term benefits. The long-term benefits include improving the social, economic and environmental aspects of sustainability during the design and construction phases in Egypt. In the short term, application of the strategy will improve the cooperation between design and construction teams, reduce the negative impact of CW production and enhance the quality of construction projects in Egypt.

Despite the need to reduce CW during DP, a practical strategy is lacking in Egypt, where laws are focused on dealing with CW after its existence. This research studied a topic that received scant attention in construction literature. It developed and validated a strategy to reduce CW during DP, which represents a synthesis that is novel and creative in thought and adds value in a manner that has not been previously explored.
