The Multilateralisation of Soviet Bloc Security: The Hungarian Revolution from an Eastern European Perspective

The Hungarian Revolution is often analysed in a national context or from the angle of Hungarian-Soviet relations. From this perspective, the Eastern European satellites seem mere puppets and the Soviet bloc a monolith. Archival evidence nevertheless shows that the Kremlin actually attempted to build a new kind of international relations after Stalin’s death in 1953, in which the Eastern European leaders would gain more scope for manoeuvre. This attempt at liberalisation even facilitated the uprisings in Hungary in 1956. Avoiding a teleological approach to the Hungarian Revolution, this article argues that the Soviet invasion was neither inevitable, nor wholly unilateral. Khrushchev even sought to legitimise the invasion in bilateral and multilateral consultations. There was a mutual interest in sacrificing Hungary’s sovereignty to safeguard the communist monopoly on power. This multilateralisation of Soviet bloc security is an important explanatory factor in an analysis of the Revolution and its repercussions in Eastern Europe.

Empire's Children: Soviet Childhood in the Age of Revolution

Ideas of childhood and citizenship stood at the center of the Soviet Union’s empire-building project during the 1920s and 1930s. After the 1917 Revolution the Bolsheviks were faced with the challenge of establishing a new state structure and governing a vast territory inherited from its tsarist predecessor. In the early years of the Soviet project, new leaders enlisted a cadre of professionals tasked with not only creating the norms of childhood and the everyday, but also implementing policies to modernize habits and values of the empire’s younger citizens. To understand how children became a prime focus of Soviet imperial and ethno-cultural politics, my dissertation employs discourse analysis and compares the ways in which Soviet imperial policies were implemented in two ethnically different regions: the Buddhist Republic of Kalmykia as the colonial case study and Moscow as the Metropole. The current project examines newspapers, treatises, and inspectors’ reports over the span of twenty years. It finds that the Bolsheviks’ initial values and discourses in the realm of children’s education, health, leisure and nutrition, all which were scientifically designed to transform children into ideal Soviet and modern citizens, changed over time as a result of the competing ideologies among local elites and the challenges they faced while intervening in children’s everyday lives. The most significant conclusion in this dissertation reveals that, contrary to previous scholarly arguments, the modernization projects that took place in Moscow and Kalmykia were more similar in the challenges and outcomes that local officials faced when implementing state policies.

The Hungarian Revolution of 1956 at Sixty Years, Liberal Reform, and the Search for a Useable Past

The story of the 1956 Hungarian Revolution at sixty years remains contested. The current center-right government led by Prime Minister Viktor Orbán at once embraces the Revolution and yet at the same time trumpets the failure of the liberal states of the West. Hungarians are encouraged to view the authoritarian politics of Vladmir Putin as a successful model worthy of emulation. In this light the liberal state envisioned by many of the revolutionaries, let alone the liberal state expected by the European Union stands in contrast with one of the principal tenets of the ruling FIDESz/Christian Democrat (KDNP) coalition. At the same time, the current yearning for an illiberal state accords with a strand of desire more akin to those who supported Cardinal Mindszenty during the Revolution and by extension his sympathy for the authoritarian regime of Miklós Horthy.

China's Involvement in the Hungarian Revolution, October-November 1956

The 1956 crises in the Soviet Bloc states, and the Hungarian October events in particular, had a profound impact on China's international and domestic policies. The Chinese Communist Party leadership – party chairman Mao Zedong in particular – had by the end of mid-1950s begun to conceive of "a great Chinese revolution," which would largely take the form of large-scale industrial modernization. At the same time, China's awareness that it could develop into a leading player in the international socialist camp led Mao and his colleagues to actively intervene on the East European scene, posing an implicit challenge to the Soviet dominance in the bloc. The apparent desire of the Hungarian and Polish people to break free from Stalinist socialism, and the real risk, as Mao saw it, of the bloc foundering, convinced the Chinese Party that only reforming institutional socialism and revising the Stalinist pattern of inter-state relations could keep the camp intact.

Vortex evolution in the wake of accelerating low-aspect-ratio plates and three-dimensional bodies of revolution

To find examples of effecient locomotion and manoeuvrability, one need only turn to the elegant solutions natural flyers and swimmers have converged upon. This dissertation is specifically motivated by processes of evolutionary convergence, which have led to the propulsors and body shapes in nature that exhibit strong geometric collapse over diverse scales. These body features are abstracted in the studies presented herein using low-aspect-ratio at plates and a three-dimensional body of revolution (a sphere). The highly-separated vortical wakes that develop during accelerations are systematically characterized as a function of planform shape, aspect ratio, Reynolds number, and initial boundary conditions. To this end, force measurements and time-resolved (planar) particle image velocimetry have been used throughout to quantify the instantaneous forces and vortex evolution in the wake of the bluff bodies. During rectilinear motions, the wake development for the flat plates is primarily dependent on plate aspect ratio, with edge discontinuities and curvature playing only a secondary role. Furthermore, the axisymmetric case, i.e. the circular plate, shows strong sensitivity to Reynolds number, while this sensitivity quickly diminishes with increasing aspect ratio. For rotational motions, global insensitivity to plate aspect ratio has been observed. For the sphere, it has been shown that accelerations play an important role in the mitigation of flow separation. These results - expounded upon in this dissertation - have begun to shed light on the specific vortex dynamics that may be coopted by flying and swimming species of all shapes and sizes towards efficient locomotion.

Integrating Machine Learning Paradigms for Predictive Maintenance in the Fourth Industrial Revolution era

In the last decade, manufacturing companies have been facing two significant challenges. First, digitalization imposes adopting Industry 4.0 technologies and allows creating smart, connected, self-aware, and self-predictive factories. Second, the attention on sustainability imposes to evaluate and reduce the impact of the implemented solutions from economic and social points of view. In manufacturing companies, the maintenance of physical assets assumes a critical role. Increasing the reliability and the availability of production systems leads to the minimization of systems’ downtimes; In addition, the proper system functioning avoids production wastes and potentially catastrophic accidents. Digitalization and new ICT technologies have assumed a relevant role in maintenance strategies. They allow assessing the health condition of machinery at any point in time. Moreover, they allow predicting the future behavior of machinery so that maintenance interventions can be planned, and the useful life of components can be exploited until the time instant before their fault. This dissertation provides insights on Predictive Maintenance goals and tools in Industry 4.0 and proposes a novel data acquisition, processing, sharing, and storage framework that addresses typical issues machine producers and users encounter. The research elaborates on two research questions that narrow down the potential approaches to data acquisition, processing, and analysis for fault diagnostics in evolving environments. The research activity is developed according to a research framework, where the research questions are addressed by research levers that are explored according to research topics. Each topic requires a specific set of methods and approaches; however, the overarching methodological approach presented in this dissertation includes three fundamental aspects: the maximization of the quality level of input data, the use of Machine Learning methods for data analysis, and the use of case studies deriving from both controlled environments (laboratory) and real-world instances.

Transitional Justice as a Post-Revolution Constitutional Arrangement: A Law and Economics Approach

This dissertation addresses the timely questions of transitional justice (TJ) in the aftermath of revolutions against autocratic regimes, dealing with TJ as a constitutional arrangement through the lenses of constitutional economics. After an introductory chapter, chapter 2 deals with why nations rarely adopt meaningful TJ processes in the first place, it then explains the limitations of civil society as the arbiter, facilitator, and enforcer of TJ policies. Chapter 3 tackles the question of which mechanisms to choose? It uses the UN Guidelines on TJ that sets five principal TJ mechanisms. It provides a cost-benefit analysis (CBA) of each mechanism and suggests policy implications accordingly. The CBA inspires chapter 4 analysis, suggesting a tradeoff between restrictive fair trial standards under constitutional laws and justice considerations. The tradeoff explains the suggested efficiency of the balanced TJ approaches that combine trials and amnesties. This approach is used for the case study analysis of TJ in Tunisia after the 2011 revolution in chapter 5. The chapter presents the first index of TJ mechanisms in Tunisia through novel data collected by the author. It shows an ultimate TJ design that ended with a modest harvest in the application. The lack of cooperation between the Tunisian parties, added to the absence of transparency in many TJ measures, threatens any possible positive outcomes of the partial TJ process. It is also alarming regarding constitutional compliance in a system that – until recently - was considered the only democracy in the Arab region. Chapter 6 is a summary

Investigating the learning potential of the Second Quantum Revolution: development of an approach for secondary school students

In recent years we have witnessed important changes: the Second Quantum Revolution is in the spotlight of many countries, and it is creating a new generation of technologies. To unlock the potential of the Second Quantum Revolution, several countries have launched strategic plans and research programs that finance and set the pace of research and development of these new technologies (like the Quantum Flagship, the National Quantum Initiative Act and so on). The increasing pace of technological changes is also challenging science education and institutional systems, requiring them to help to prepare new generations of experts. This work is placed within physics education research and contributes to the challenge by developing an approach and a course about the Second Quantum Revolution. The aims are to promote quantum literacy and, in particular, to value from a cultural and educational perspective the Second Revolution. The dissertation is articulated in two parts. In the first, we unpack the Second Quantum Revolution from a cultural perspective and shed light on the main revolutionary aspects that are elevated to the rank of principles implemented in the design of a course for secondary school students, prospective and in-service teachers. The design process and the educational reconstruction of the activities are presented as well as the results of a pilot study conducted to investigate the impact of the approach on students' understanding and to gather feedback to refine and improve the instructional materials. The second part consists of the exploration of the Second Quantum Revolution as a context to introduce some basic concepts of quantum physics. We present the results of an implementation with secondary school students to investigate if and to what extent external representations could play any role to promote students’ understanding and acceptance of quantum physics as a personal reliable description of the world.

Non-thermal phenomena in galaxy clusters: the LOFAR revolution

Turbulence introduced into the intra-cluster medium (ICM) through cluster merger events transfers energy to non-thermal components (relativistic particles and magnetic fields) and can trigger the formation of diffuse synchrotron radio sources. Owing to their steep synchrotron spectral index, such diffuse sources can be better studied at low radio frequencies. In this respect, the LOw Frequency ARray (LOFAR) is revolutionizing our knowledge thanks to its unprecedented resolution and sensitivity below 200 MHz. In this Thesis we focus on the study of radio halos (RHs) by using LOFAR data. In the first part of this work we analyzed the largest-ever sample of galaxy clusters observed at radio frequencies. This includes 309 Planck clusters from the Second Data Release of the LOFAR Two Metre Sky Survey (LoTSS-DR2), which span previously unexplored ranges of mass and redshift. We detected 83 RHs, half of which being new discoveries. In 140 clusters we lack a detected RH; for this sub-sample we developed new techniques to derive upper limits to their radio powers. By comparing detections and upper limits, we carried out the first statistical analysis of populations of clusters observed at low frequencies and tested theoretical formation models. In the second part of this Thesis we focused on ultra-steep spectrum radio halos. These sources are almost undetected at GHz frequencies, but are thought to be common at low frequencies. We presented LOFAR observations of two interesting clusters hosting ultra-steep spectrum radio halos. With complementary radio and X-ray observations we constrained the properties and origin of these targets.

Semi-determinate Growth Habit Adjusts The Vegetative-to-reproductive Balance And Increases Productivity And Water-use Efficiency In Tomato (solanum Lycopersicum).

Tomato (Solanum lycopersicum) shows three growth habits: determinate, indeterminate and semi-determinate. These are controlled mainly by allelic variation in the SELF-PRUNING (SP) gene family, which also includes the florigen gene SINGLE FLOWER TRUSS (SFT). Determinate cultivars have synchronized flower and fruit production, which allows mechanical harvesting in the tomato processing industry, whereas indeterminate ones have more vegetative growth with continuous flower and fruit formation, being thus preferred for fresh market tomato production. The semi-determinate growth habit is poorly understood, although there are indications that it combines advantages of determinate and indeterminate growth. Here, we used near-isogenic lines (NILs) in the cultivar Micro-Tom (MT) with different growth habit to characterize semi-determinate growth and to determine its impact on developmental and productivity traits. We show that semi-determinate genotypes are equivalent to determinate ones with extended vegetative growth, which in turn impacts shoot height, number of leaves and either stem diameter or internode length. Semi-determinate plants also tend to increase the highly relevant agronomic parameter Brix×ripe yield (BRY). Water-use efficiency (WUE), evaluated either directly as dry mass produced per amount of water transpired or indirectly through C isotope discrimination, was higher in semi-determinate genotypes. We also provide evidence that the increases in BRY in semi-determinate genotypes are a consequence of an improved balance between vegetative and reproductive growth, a mechanism analogous to the conversion of the overly vegetative tall cereal varieties into well-balanced semi-dwarf ones used in the Green Revolution.

Nature-inspired Enzymatic Cascades To Build Valuable Compounds.

Biocatalysis currently is focusing on enzymatic and multi-enzymatic cascade processes instead of single steps imbedded into chemical pathways. Alongside this scientific revolution, this review provides an overview on multi-enzymatic cascades that are responsible for the biosynthesis of some terpenes, alkaloids and polyethers, which are important classes of natural products. Herein, we illustrate the development of studies inspired by multi- and chemo-enzymatic approaches to build the core moieties of polyethers, polypeptide alkaloids, piperidines and pyrrolidines promoted by the joint action of oxidoreductases, hydrolases, cyclases, transaminases and imine reductases.
