What kinds of support do interstate rivals provide to domestic actors in ongoing civil wars? And how do domestic actors utilize the support they receive? This chapter answers these questions by comparing Iranian and Saudi military and non-military (mediation, foreign aid and religious soft-power promotion) support to the Houthis and to the Government of Yemen (GoY) during the Saada wars (2004–2010) and the internationalized civil war (2015–2018). It also focuses on the processes through which the GoY and the Houthis have utilized this support for their own strategic purposes. This chapter applies a structured, focused comparison methodology and relies on data from a review of both primary and secondary sources complemented by 14 interviews. This chapter finds that there were less external interventions in the conflict in Saada than in the internationalized civil war. During the latter, a broader set of intervention strategies enabled further instrumentalization by domestic actors, which in turn contributed to the protracted nature of the conflict. This chapter contributes to the literature on interstate rivalry and third-party intervention. The framework of analysis is applicable to civil wars that experience intervention by rivals, such as Syria or Libya.

Private telecommunication companies in Yemen face huge challenges to improve their competitive position. Many of them suffer from performance management systems (PMS) that are not aligned nor integrated and do not give adequate support. This research aims at identifying the current state and quality of PMS in Yemeni private telecom companies and developing recommendations that will assist in improving their performance and competitive position.

As research tools, the performance management analysis – used to measure the quality of a PMS – and the high performance organization (HPO) framework – used to measure the quality of an organization and thereby its ability to achieve sustainable high competitive performance – are applied at three Yemeni private telecom companies.

There is a considerable performance gap between the actual and the ideal PMS in the Yemeni private telecom companies; this performance gap is highly correlated with competitive performance in a negative relationship. Both the structural and behavioral dimensions’ performance gaps have a significant impact on competitive performance, with the impact of the behavioral dimensions being considerably higher than that of the structural dimensions.

The current academic literature on HPOs and PMS in Yemen is scarce. This study adds knowledge to these areas, and thus provides a basis for further study. This research results also help managers of the Yemeni private telecom companies to take strategic action to redesign and implement new and improved PMS to increase their competitive performance.

Road projects are essential for poverty reduction and the socio-economic development of Yemeni people living in rural areas. Rural access programs, which are mainly sponsored by foreign countries and international organisations, are often delayed. The purpose of this paper is to identify the delay factors of rural road projects with a focus on stakeholder-related factors.

The data was collected using a questionnaire survey from 164 participants representing 7 groups, namely, owner, government, donors, consultants, designers, contractors and beneficiaries. The data was analysed using the partial least squares path modelling (PLS-SEM).

The results show that the identified factors contribute to 16% of the variance of project delay. Donor and government-related factors have a significant relationship with delay. Further analysis of data using the IPMA procedure in PLS-SEM revealed the top factors contributing to delay, which are project selection criteria imposed by donors, government bureaucracy, decision-making process, weak laws and guidelines that regulate the work of project implementation units, procurement procedures, delay of payment to contractor and delay of transactions.

The timely completion of rural road projects can have a positive impact on the current and future rural access programs aiming to reduce poverty and increase access to health and education services of over 70% of Yemeni people living in rural areas. Such programs will reduce the misfortune of displaced people due to the ongoing war in the country.

Although competitor orientation (CO) has been given great attention, its link to firm performance (FP) is still unclear. The reason behind this may be attributed to the fact that the CO–FP relationship depends on several contingencies. The purpose of this paper is to simultaneously explore the separate and combined moderating effects of marketing ethics (ME) and competitive intensity (CI) in the CO–FP relationship.

The participants in this study were managers or owners from 289 manufacturing SMEs located in two regions in Yemen (i.e. Sana’a and Taiz). Hierarchical regression analysis using PROCESS Macro V. 3.5 in SPSS was performed to analyze the data collected.

The obtained results reveal that ME in fact positively moderates the CO–FP relationship and, importantly, this effect is not influenced by CI.

The findings of this paper provide advantageous insights for managers and decision-makers for SMEs as it is expected that they demonstrate a greater commitment to the practice of ME in their firms. This has implications that with the practice of ME, it is expected that SMEs will be able to use the full potential of CO to improve their performance at a low level of CI.

This study contributes to widening the studies on CO, ME, CI and SMEs in a different context. In addition, it adds to the knowledge by exploring the combined moderating influence of internal (e.g. ME) and external factors (e.g. CI) when examining the CO–FP relationship.

The variance between the winning bid and the owner's estimated cost (OEC) is one of the construction management risks in the pre-tendering phase. The study aims to enhance the quality of the owner's estimation for predicting precisely the contract cost at the pre-tendering phase and avoiding future issues that arise through the construction phase.

This paper integrated artificial neural networks (ANN), deep neural networks (DNN) and time series (TS) techniques to estimate the ratio of a low bid to the OEC (R) for different size contracts and three types of contracts (building, electric and mechanic) accurately based on 94 contracts from King Saud University. The ANN and DNN models were evaluated using mean absolute percentage error (MAPE), mean sum square error (MSSE) and root mean sums square error (RMSSE).

The main finding is that the ANN provides high accuracy with MAPE, MSSE and RMSSE a 2.94%, 0.0015 and 0.039, respectively. The DNN's precision was high, with an RMSSE of 0.15 on average.

The owner and consultant are expected to use the study's findings to create more accuracy of the owner's estimate and decrease the difference between the owner's estimate and the lowest submitted offer for better decision-making.

This study fills the knowledge gap by developing an ANN model to handle missing TS data and forecasting the difference between a low bid and an OEC at the pre-tendering phase.

This paper provides a state-of-the-art review of the financial development in the Middle East and Central Asia (MECA) and examines its impact on its economic growth.

The authors use a Panel Data Regression Analysis on a sample of 21 countries in MECA for the period 2008–2018.

Using the financial development indices and subindices retrieved from IMF, the study finds that the whole region has a below average index compared to other developing regions. However, this hides a great deal of variation across MECA countries. Surprisingly, financial development does not necessarily contribute to economic growth. It seems that some developing countries are still not predisposed to benefit from financial development due to several obstacles.

The authors recommend policymakers and regulators in MECA to promote financial stability and keep inflation in check so that economic agents can reap the fruits of financial development and foster economic growth. Policymakers should also stimulate competition in the financial sector, build skillful human capital, attract foreign direct investments, strengthen supervision and forensic audit and more importantly reinforce the independence of central banks.

The authors mitigate the shortcomings of single indicators as proxies for financial development by using the IMF Financial Development index that captures the depth, access and efficiency of both financial institutions and financial markets. The authors employ lower-middle-, upper-middle and high-income country groups to test the magnitude of income level on the relationship between financial development and economic growth.

Burdened by undernutrition, micronutrient deficiencies and overweight and obesity as a consequence of both internal conflict and the global nutrition transition, Iraq is in need of adequate public health nutrition education to mitigate nutrition-related outcomes and risks. To address nutrition-related health outcomes, trained nutrition professionals are warranted. This paper examines current nutrition-affiliated programs offered across post-secondary institutions in Iraq.

An electronic review of universities and colleges’ websites, department webpages and academic programs’ homepages and resources of all the private and public universities in Iraq was conducted to find programs related to nutrition, nutrition sciences and dietetics.

All identified programs belonged to the governmental sector, were administered and financed by the Iraqi Government and were under the purview of the Iraqi Ministry of Higher Education. The review highlighted a predominant focus on food sciences in agricultural departments rather than public health or clinical nutrition. Advanced education in topics such as human metabolism, medical nutrition therapy and public health nutrition are required to adequately address over- and undernutrition in Iraq.

The current state of public health and nutrition-related postsecondary education in Iraq warrants an increased emphasis on clinical and public health nutrition education. Despite a commendable focus on food science studies, the country’s ongoing challenges with obesity, nutrition-related noncommunicable diseases and conflict-associated food insecurity signal an urgent need for balancing this focus with grounding in postsecondary training in public health nutrition.

This study aims to empirically investigate the impact of oil prices, political instability and changes in stability on the bank diversification of the two types of banking systems in the Middle East and North African (MENA) countries.

The study uses bank diversification, stability measurement of probability of default and Zscore by adopting the generalised method of moment for the data between 2007 and 2021. The authors estimate short- and long-run dynamic panel analysis and a robustness test.

The findings reveal that Islamic banks are slightly lower in diversification and stability than conventional peers in the region. Diversification increases with a positive increase in GDP growth, law and order, political stability, bank size, asset quality, oil price, return on equity, profitability and change in banking asset-based stability. The authors found consistency in the two stability measurements in both short- and long-run situations.

Despite the change in banking stability and economic growth and oil prices improved diversification, banks in the region are not diversifying during the crisis period and political instability. Therefore, policymakers should improve mechanisms to monitor the crisis and political unrest to avoid the systemic risk that adversely affects the system through macro-financial linkages in the region.

This study uses change dual stability measurements and oil prices to predict MENA region bank diversification. The authors extended the banking literature by estimating the relationship between crisis periods, political and banking stability, oil prices and other institutional indicators of banking diversification. This study uncovers the effect of the global crisis period on banking diversification and the impact of banking stability changes and validates the models through robustness tests.

The purpose of this paper is to develop a practical implementation blueprint for the attainment of food security for all Nigerians based on sustainable agricultural practices.

This paper conducted a critical review of 66 peer-reviewed empirical articles on various sustainable agricultural case studies. The evidence obtained from this review and the in-depth knowledge of the authors regarding the Nigerian agricultural landscape was used to develop a practical implementation blueprint for achieving food security in the country.

The food security for all Nigerians (FOSFAN) blueprint was developed and comprising of eight practical and interconnected steps. These steps take into consideration the synergistic effort of the government, the ministry of agriculture and its corresponding agencies in ensuring that farmers attain sustainable practices in their endeavour.

The findings of this paper will contribute to existing literature on food security and will also serve as a baseline for deeper empirical exploration of the impact of sustainable agricultural practices on food security in Nigeria (a country in the Sub-Saharan region).

The FOSFAN blueprint provides a practical and comprehensive step-by-step guide, which the Nigerian Ministry of Agriculture can use to achieve food security for all Nigerians.

This paper is addressed towards the development of food security plan in the Nigerian context in which the Nigerian Government ensures the availability of food to all its citizens in a bid to achieve “Zero Hunger”, which is the second Sustainable Development Goal.

The FOSFAN blueprint is a proactive guide that takes into consideration the importance of cultural and socioeconomic nuances in the development of a sustainable agriculture policy in a developing country context.
