Structural violence (SV) is related to the uneven distribution of resources which then leads to social exclusion and marginalisation of people. Johan Galtung (1969) also refers to it as social injustice and it is characterised by unequal access to education, health, water, food, shelter and other basic services. SV manifests itself through different forms of exclusion supported through both public and private institutions. Without support to address economic and educational opportunities, Zimbabwean youth continue to experience SV and high levels of social inequality (Chimucheka, 2012). Conflict transformation (CT) can help address SV since it provides processes and ways to build something desired thus altering the manifestation of the conflict (Waldman, 2009). CT involves action between parties that leads to both social change and justice (M. Evans, 2016). Social entrepreneurship (SE) can be used as a CT tool because it (i) identifies an unjust equilibrium that perpetuates exclusion and marginalisation, (ii) identifies opportunities and innovatively challenges the status quo to add social value and (iii) provides a better future for the marginalised communities through creating a new and stable alternative equilibrium (Baporikar, 2016). This chapter discusses the SV transformation model which the author tested to address the disparities faced by youth in an urban area in Zimbabwe. The action research, which took place between January and May 2017, was carried out in combination with capacity building, social support systems and community participation to address some of the SV indicators prevalent in the community. Whilst SE showed great potential in tackling SV in the community study, findings also reveal contestations between theory and practice. Some of the barriers identified in the field include the community’s failure to self-organise, lack of financial resources and buy-in from the local government. Future research could test the model in multiple settings and over longer periods to see its effectiveness.

From a theoretical point of view, a spatial econometric model can contain both a spatially lagged dependent variable (spatial lag) and a spatially autocorrelated error term (spatial error). However, such models are rarely used in practice. This is because (assuming a lattice model approach is used for both the spatial lag and spatial error) the model is difficult to estimate¹ unless the weight matrices are different for the spatial lag and the spatial error.

Prejudice against Jews was part of the landscape in the Union of South Africa long before Nazism made inroads into the country during the 1930s, at which stage Jews constituted approximately 4.6% of the country’s white (or European) population. Aggressive Afrikaner nationalism was marked by fervent attempts to proscribe Jewish immigration. By 1939, Jewish immigration was included as an official plank in the political platform of the opposition Purified National Party led by Dr D.F. Malan, along with a ban on party membership for Jews residents in the Transvaal province. Racial discrimination, in a country with diversified ethnic elements and intense political complexities, was synonymous with life in the Union long before the Apartheid system, with its official policy of enforced legal, political and economic segregation, became law in May 1948 under Dr Malan’s prime ministership. Although the Jews, while maintaining their own subcultural identity, were classified within South Africa’s racial hierarchy as part of the privileged white minority, the emergence of recurrent anti-Jewish stereotypes and themes became manifest in a country permeated by the ideology of race and white superiority. This was exacerbated by the growth of a powerful Afrikaner nationalist movement, underpinned by conservative Calvinist theology. This chapter focusses on measures taken in South Africa by organisational structures within the political sphere to restrict Jewish immigration between 1930 and 1939 and to do so on ethnic grounds. These measures were underscored by radical Afrikaner nationalism, which flew in the face of the principles of ethics and moral judgement.

How should we make sense of Europe's current malaise? Focused on the great recession, the European Union (EU)'s architecture, or diverging national interests, the literature offers useful economic, institutional, and political explanations. It is our contention that, however diverse, these works share one important limitation: a tendency to focus on rather immediate causes and consequences and not to step back with historical or comparative perspectives to gain a “longer” view of the dynamics at work. In this article, we begin by examining parallels between the EU's current conditions and the Austrian-Hungarian Empire. Then, introducing the articles contained in this special issue, we raise research questions pertaining to long-term historical, social, cultural, economic, and political factors. Are the current challenges unprecedented or do they have roots or connections to past events and developments? Is there a European trajectory into which we can contextualize current events? Are there bright spots, and what do they suggest about Europe's present and future? To engage in such questions, the papers leverage the insights of historical and comparative sociology, as well as comparative politics. In so doing, they offer analyses that see the EU as an instance of state formation. They propose that a key dimension of tension and possible resolution is the classic problem of sovereignty. They grapple with the question of identity and institutions, exploring in that context the extent and limit of citizens' support for more Europe. And they delve into the nature of the nationalist and populist sentiments within and across European countries.

This study has covered many types of solar-powered air-conditioning systems that may be used as an alternative to traditional electrically powered air-conditioning systems in order to reduce energy usage. Solar adsorption air cooling is a great alternative to traditional vapor compression air-conditioning. Solar adsorption has several advantages over traditional vapor-compression systems, including being a green cooling technology which uses solar energy to drive the cycle, using pure water as an eco-friendly HFC-free refrigerant, and being mechanically simple with only the magnetic valves as moving parts. Several advancements and breakthroughs have been developed in the area of solar adsorption air-conditioners during the previous decade. However, further study is required before this technology can be put into practise. As a result, this book chapter highlights current research that adds to the understanding of solar adsorption air-conditioning technologies, with a focus on practical research. These systems have the potential to become the next iteration of air-conditioning systems, with the benefit of lowering energy usage while using plentiful solar energy supplies to supply the cooling demand.
