The purpose of this paper was to study the genetic variability, heritability, heat tolerance indices and phenotypic and genotypic correlation studies for traits of 250 elite International Center for Agricultural Research in the Dry Areas (ICARDA) bread wheat genotypes under high temperature in Wad Medani, Center in Sudan.

Bread wheat is an important food on a global level and is used in the form of different products. High temperature associated with climate change is considered to be a detrimental stress in the future on world wheat production. A total of 10,250 bread wheat genotypes selected from different advanced yield trials introduction from ICARDA and three checks including were grown in two sowing dates (SODs) (1st and 2nd) 1st SOD heat stress and 2nd SOD non-stress at the Gezira Research Farm, of the Agricultural Research Corporation, Wad Medani, Sudan.

An alpha lattice design with two replications was used to assess the presence of phenotypic and genotypic variations of different traits, indices for heat stress and heat tolerance for 20 top genotypes and phenotypic and genotypic correlations. Analysis of variance revealed significant differences among genotypes for all the characters. A wide range, 944-4,016 kg/ha in the first SOD and 1,192-5,120 kg/ha in the second SOD, was found in grain yield. The average yield on the first SOD is less than that of the secondnd SOD by 717.7 kg/ha, as the maximum and minimum temperatures were reduced by 3ºC each in the second SOD when compared to the first SOD of the critical stage of crop growth shown.

Similar wide ranges were found in all morpho-physiological traits studied. High heritability in a broad sense was estimated for days to heading and maturity. Moderate heritability estimates found for grain yield ranged from 44 to 63.6 per cent, biomass ranged from 37.8 to 49.1 per cent and canopy temperature (CT) after heading ranged from 44.2 to 48 per cent for the first and secondnd SODs. The top 20 genotypes are better than the better check in the two sowing dates and seven genotypes (248, 139, 143, 27, 67, 192 and 152) were produced high grain yield under both 1st SOD and 2nd SOD.

The same genotypes in addition to Imam (check) showed smaller tolerance (TOL) values, indicating that these genotypes had a smaller yield reduction under heat-stressed conditions and that they showed a higher heat stress susceptibility index (SSI). A smaller TOL and a higher SSI are favored. Both phenotypic and genotypic correlations of grain yield were positively and significantly correlated with biomass, harvest index, number of spikes/m², number of seeds/spike and days to heading and maturity in both SODs and negatively and significantly correlated with canopy temperature before and after heading in both SODs.

Genetic variations, heritability, heat tolerance indices and correlation studies for traits of bread wheat genotypes under high temperature

Although there are over 55,000 social enterprises operating in Egypt, the social entrepreneurship field is still failing to create the desired social change. This paper aims to explore the challenges faced by the field with a special focus on government related challenges as well as offer a set of recommendations to the Egyptian government to enhance the field.

The research was carried out in two phases; reviewing the literature around the topic through a secondary research followed by an empirical research interviewing four social enterprises, the ministry of social solidarity and experts in the field of social entrepreneurship.

The paper arrived to several challenges and they were organized into three main themes: challenges related to policy-making and other legal aspects; challenges related to institutional and operational support; and challenges related to social, educational and cultural awareness of the field and its ecosystem. The paper also came up with a set of nine recommendations directed to the Egyptian Government.

The originality and value of this research is that it offers first hand viewpoints of the challenges facing the field of social entrepreneurship in Egypt as well as offer practical recommendations to the Egyptian Government to overcome them.

Managerial effectiveness is considered as an essential element for sustainable development and competitive advantage for organisations, and its core conceptualisation revolves around the capability of management to manage self, subordinates and relationships. However, very few research addressed this important phenomenon; this study aims to fill this gap by investigating the mediating role of Islamic work ethics between leadership styles and managerial effectiveness.

Data collection was done through a structured questionnaire, and the hypothesized relationships were tested with the help of SmartPLS.

Results of the statistical analysis showed that transformational and transactional leadership styles are positively associated with managerial effectiveness. Also, Islamic work ethics mediated the association between transactional leadership and managerial effectiveness, and however, no mediation effect of Islamic work ethics was found in the relationship of transformational leadership and managerial effectiveness

Although volumes of research have been conducted into the nature of management and leadership over the past 50 years or so, there have been significant shortcomings in terms of little attention having been given to the issue of managerial effectiveness, lack of generalizability of findings and lack of relevance and utility; thus, this study contributed to human resource management literature by providing a macro-level model to measure managerial effectiveness.

Years after the 2011 uprising Egypt, it seems that the country’s non-Islamist parties are still included in the political game. After significant alterations in their political sphere by mid-2013 at the advent of the Muslim Brother exclusion and the subsequent discrediting of Salafi al-Nour party, non-Islamist parties took clear part in the mobilization for presidential elections (2014, 2018) and competed for legislative seats in 2015. Nonetheless, it is difficult to expect them to turn into long-term key political players with clear-cut ideological postures, unique platforms and strong grass root mobilization. With the exception of the electoral gains scored by numbered parties like Free Egyptians’ party and Nation’s Future in 2015 legislative elections, these parties seem to be lagging behind esp. in terms of their popular base; who became winners at the advent of the radical exclusion of the MB from July 2013 onwards.

This paper is based on archival research and guided by basic assumptions of rational choice institutionalism, mainly game-theoretic versions of the approach. It is divided into four sections, three of them are chronological and the last one is thematic.

Egypt’s non-Islamists engaged in the post-2011 political sphere, with strong Islamist rivals crippling their political chances in the first two years following the 2011 uprising. They surely capitalized on the exclusion and discrediting of the latter, but they suffered lack of ideological clarity and fragmentation from 2011 onwards with no enough evidence these weaknesses were surpassed after Islamists were “out of their way”. The only strand of non-Islamist parties which came out as “game winners” were those possessing the resources and enjoying overt “friendly” relations with al-Sisi regime. Nonetheless, internal conflicts inside key secularist parties shed light on their capacity to turn into long-term players in Egypt’s political sphere.

Very few papers were published on Egypt’s secularists parties after the 2011 uprising from the perspective of the alteration that occurred in their political environment affecting their political weight and gains. More generally, literature on non-ruling parties in authoritarian contexts mostly reduce these parties to secondary roles allocated by ruling regimes. The paper seeks to overcome both shortages.

Recently, various policies have been implemented in Saudi Arabia to reform science teaching at K-12 levels in order to focus on critical thinking, inquiry-based learning, and problem solving. Research is needed to explore the adequacy of teacher preparation programs to determine whether these programs sufficiently prepare Saudi science teachers to teach according to these new reforms. This study explores the challenges that Saudi pre-service science teachers face in these higher education programs. Results indicated that graduates of the programs studied were satisfied with their experiences; however, various concerns were expressed by some pre-service teachers regarding the theory-practice gap between their university coursework and field experiences, and the supervision structures and functions in place for the professional experiences component. Modifications to the teacher preparation programs are suggested in order to address these concerns and to successfully enact reforms in science education in Saudi Arabia.

Incorporating flipped learning (FL) into teaching English as a foreign language may improve student learning outcomes. This study gathered information on Saudi EFL teachers' readiness and willingness to apply FL. So, it aims to describe Saudi EFL teachers' readiness and willingness to apply FL in language classrooms and to find suitable guidelines for Saudi EFL professional development (PD) designers to follow.

This descriptive study involved 153 male and female Saudi EFL teachers as participants, investigating the perspectives and perceptions of these teachers within the context of foreign language teaching in Saudi Arabia. Surveys in Qualtrics were employed as the primary data collection tool for the study.

Results showed that teachers' self-efficacy of their current teaching was high. Most participants had positive attitudes and abilities related to FL, although they also identified potential challenges related to its engagement and assessment. Teachers expressed a strong willingness to participate in PD in this area, with a preference for online videos and group workshops.

The study emphasizes the importance of PD for Saudi EFL teachers. In addition, it offers guidelines for planning effective PD.
