Bibliography 273 Abstract The nation-state is now the dominant form of sovereign statehood, however, a century and a half ago the political map of Europe comprised only a handful of sovereign states, very few of them nations in the modern sense. Balkan historiography often tends to minimize the complexity of nation-building, either by referring to the national community as to a monolithic and homogenous unit, or simply by neglecting different social groups whose consciousness varied depending on region, gender and generation. Further, Bulgarian and Serbian historiography pay far more attention to the problem of "how" and "why" certain events have happened than to the emergence of national consciousness of the Balkan peoples as a complex and durable process of mental evolution. This dissertation on the concept of nationality in which most Bulgarians and Serbs were educated and socialized examines how the modern idea of nationhood was disseminated among the ordinary people and it presents the complicated process of national indoctrination carried out by various state institutions.

  • Anti-Communism, Neoliberalisation, Fascism by Bozhin Stiliyanov
    Post-Socialist Blues Within Real Existing Capitalism: Anti-Communism, Neoliberalisation, Fascism by Bozhin Stiliyanov Traykov A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy Department of Sociology University of Alberta © Bozhin Stiliyanov Traykov, 2020 Abstract This project draws on Alex William’s (2020) contribution to Gramscian studies with the concept of complex hegemony as an emergent, dynamic and fragile process of acquiring power in socio- political economic systems. It examines anti-communism as an ideological element of neoliberal complex hegemony in Bulgaria. By employing a Gramcian politico-historical analysis I explore examples of material and discursive ideological practices of anti-communism. I show that in Bulgaria, anti-communism strives to operate as hegemonic, common-sensual ideology through legislative acts, production of historiography, cultural and educational texts, and newly invented traditions. The project examines the process of rehabilitation of fascist figures and rise of extreme nationalism, together with discrediting of the anti-fascist struggle and demonizing of the welfare state within the totalitarian framework of anti-communism. Historians Enzo Traverso (2016, 2019), Domenico Losurdo (2011) and Ishay Landa (2010, 2016) have traced the undemocratic roots of economic liberalism and its (now silenced) support of fascism against the “Bolshevik threat.” They have shown that, whether enunciated by fascist regimes or by (neo)liberal intellectuals, anti-communism is deeply undemocratic and shares deep mass-phobic disdain for political organizing of the majority. In this dissertation I argue that, in Bulgaria, anti- communism has not only opened the ideological space for extreme right and fascist politics, it has demoralized left political organizing by attacking any attempts for a politics of socio- economic justice as tyrannical.

  • Volatility Spillover from the United States and Japanese Stock Markets
    PANOECONOMICUS, 2021, Vol. 68, Issue 1, pp. 35-52 UDC 336.76(73+510]:597) Received: 28 April 2017; Accepted: 26 January 2019. https://dx.doi.org/10.2298/PAN170428003N Original scientific paper Le Dinh Nghi Volatility Spillover from the United Corresponding author Saigon University; States and Japanese Stock Markets to Ho Chi Minh City Open University, Vietnam [email protected] the Vietnamese Stock Market: [email protected] A Frequency Domain Approach Nguyen Minh Kieu Ho Chi Minh City Open University, Vietnam Summary: Using frequency domain analysis, this paper examines the volatility [email protected] spillover from the United States and Japanese stock markets to the Vietnamese stock market. Daily data of S&P 500, Nikkei 225 and VN-Index from January 01, 2012 to May 31, 2016 is used. In terms of estimation, the GARCH model is used to estimate volatilities in these stock markets; the Granger Causality Test is used to examine volatility spillover; and the test for causality in the frequency domain by Jorg Breitung and Bertrand Candelon (2006) is used to examine the volatility spillover at different frequencies. The empirical results provide two main contri- butions: (i) there is a significant volatility spillover from the United States to the Vietnamese stock markets, but the evidence of volatility spillover from the Japa- nese to the Vietnamese stock market is not found; and (ii) the volatility spillover may vary across frequency spectrum bands. To our best understanding, volatility spillover analysis using frequency domain approach was not previously reported in literature. The authors are grateful to the editors Key words: Causality, Frequency domain, Spillover, Volatility.
