The model of animal husbandry is an enduring cultural element. It undergoes transformations only as a result of the pressure of serious factors: ecological, demographic or, less frequently, religious ones. By conducting comparative analyses of faunal data from the largest ancient and Medieval civilisation centres of NE Africa, mainly from the Middle Nile, we identify the effects of such factors − the time, scope and strength of their impact on local communities. For the first time, we compare animal breeding models by communities from two Medieval, neighbouring Nubian kingdoms: Makuria and Alwa (AD 500-1200). Research shows that Makuria was dynamic, changeable and open to the adaptation of new species: pig, camel, chicken and horse. In the Southern state community of Alwa practiced a conservative, largely cattle-raising model typical of the ancient Kush civilisation (300 BCE-AD 300). Long-horned, indigenous cattle were imported to Makuria from the central Sahel, as evidenced by osteometric and isotopic data. Only local taurine shorthorn cattle were bred at Alwa, unchanged for two millennia, continuing the tradition of ancient Kush. We found that the pattern of farming and meat consumption can be an element of identity among communities living in analogous environmental, political and religious contexts.

The present paper focuses on the need of a paradigm shift in teaching learning process in which students may be given opportunity to construct knowledge by their own experiences. This paradigm shift referred to as constructivist paradigm is the need of the hour in which students may be given opportunities to reflect, develop critical thinking and problem solving abilities. The paper also focuses on the principles and strategies needed to be adopted for successful implementation of constructivism in teaching learning process.

retail investors are also important and they are also able to play a critical role in the growth of the stock market. Retail participation is particularly important for small cap companies. For some obvious reasons, institutional investors are not quite keen to invest in these companies. Retailers can be very important for the survival of small cap companies. Another important role of retail investors lies in providing a stable ownership base for companies. This is because most retail investors' trade relatively infrequently. However, all this can happen only when retail participation in the stock market is sufficiently large. The present survey provides first-hand information on the contents of retail investors' investment, and their trading habits and decision making.

The purpose of this paper was to review existing literature on leadership theories and the desired competencies of the 21st Century Organization Leader, collect and summarize empirical evidence that fits within the context of this study. The modern organization is operating in a context of complex problems that are non-predictable, dynamic and do not have definite solutions. This is coupled with the global sustainability issues of pandemics, global terrorism and environmental pollution, among others. The 21st Century leader needs to have competencies that are sustainable for the present, the future and have capabilities for survival in this digital era. The world is not static and as it evolves, so has leadership evolved and leaders require competencies that will help run the 21st century organization successfully. There are constant changes in the speed of communication, expansive networks that are needed to run organizations and the upsurge in trade volumes. All these have alt...

This article presents a materialist ecofeminist critique of neoextractivism by highlighting its historical origins and elaborating its economic policy implications in Latin America. Three questions addressed are as follows: 1) How can materialist ecofeminism contribute to understanding the current dynamics of capitalist development in the Global South, 2) why (neo)extractivism hits women hardest, and 3) to what extent and how ecofeminist movements can shape a post-extractivist transition to a just and sustainable future. The article's main argument is that exploitation and oppression in Latin America can be understood in terms of gender, race, and class and, therefore, require an intersectional analysis framework. Within this framework, post-extractivist alternatives in this region must incorporate an ecofeminist analysis to understand better how social expression systems (including sexism, white supremacy, and ecological crises) intersect and reinforce each other. In this framework, this study is intended to contribute to the growing literature and debate on the development and resistance dynamics of neoextractivism in Latin America, where long-standing racial and gender inequalities intersect with class inequalities.

Mediterranean Politics, 2023

Despite Greece's centrality in Eastern Mediterranean history and politics, the evolution, characteristics, and rationale behind the country's relations with the Arab world have yet to be identified. This article provides a close examination of post-World War II Greek foreign policy towards the Arab world across four key periods (1945-80; 1980-89; 1990-2018; and since 2019). It builds on a historical institutionalist approach in order to argue that Greece's relationship with the Arab world remained a vital pillar of the country's diplomatic strategy, albeit instrumentalised in terms of Greece's two main foreign policy pillars in the post-World War II era: maintaining the country's Western orientation and navigating the vicissitudes of Greek-Turkish relations. Thus, the Arab world has traditionally been approached by Greek policymakers in a profit maximisation manner that sought to amplify its relationship with Western powers or to respond to Turkish initiatives in the region. Aiming to provide the first systematic overview of Greek diplomatic strategy towards the Arab world, the article understands the importance of path dependence in evaluating Greek foreign policy initiatives towards the Middle East. It also seeks to contextualise current attempts at a pro-active Greek role across the region by providing necessary historic nuance and a comparative perspective.
