Persecution and Patronage: Oscar Buneman’s years in Britain
2016
The German student Oscar Bunemann, in trouble with the Nazi authorities in the mid-1930s, chose to emigrate to Britain and pursue a PhD there. After emigration, his surname appears as Buneman. On the verge of completing his degree in 1940, he was detained as an enemy alien and spent almost a year in internment. Upon release, he found work as an atomic scientist in England, and went on to lead a post-war career as a pioneering plasma physicist in the USA.We study forced migration of European scientists before and during the Second World War, and scientific patronage in the host countries. Buneman’s case is interesting from several points of view. Being a non-Jewish, non-communist, anti-Nazi …
A new indicator for higher education student performance
2014
The debate on academic achievement is a heated issue that involves all the higher education contexts. This paper attempts to provide an indicator that can make the measurement of university student performance easier and that can be easily applied to different systems, making comparisons more fair. The Italian University System is used as a starting point to make several considerations on the current measures and to build up a new performance indicator. Then, a generalization for other marking systems is shown and finally a quantile regression is performed to investigate some determinants of the new performance indicator, also with respect to the current one.
External drivers of EU differentiated cooperation: How change in the nuclear nonproliferation regime affects member states alignment
2023
Since its establishment, the Common Foreign and Security Policy (CFSP) has strived to increase convergence among EU member states. Yet, convergence remains elusive and scholars have started to explain the emergence of differentiated cooperation resulting from multiple internal EU crises. We posit that the convergence in the EU member states with respect to nuclear weapons has been fundamentally altered by the humanitarian turn to nuclear disarmament. This has led to a crystallization of differentiated subgroups among the member states, whose membership coincides with that of informal groupings active in the broader nuclear nonproliferation regime. Combining quantitative data on resolution s…
L’urbanité de l’héritage industriel La reconversion du viaduc de la High Line à New York
2015
At the heart of urban dynamics over the past few decades, the reconversion of riverside and port spaces in cities of the western world is associated with the deindustrialisation of these sites, often situated near historic city centres. This contemporary situation puts industrial heritage conversion at the centre of thinking which goes beyond the mere conservation of the original value of the buildings to question the future of cities, in relation to the notion of sustainability. In New York, after thirty years of neglect, the old railway viaduct known as the “High Line” has been transformed into an elevated, linear urban parkway. The project must be reframed within the Hudson Riverpark ope…
Negative Party Identifications as Out-Group Perceptions in Multi-Party Systems How Do They Affect Vote Choice?
2015
Although negative party identification is part of the original party identification concept by Campbell et al., it has been rarely analyzed in empirical studies. Further, the few existing studies lack a coherent conceptualization of negative partisanship, and focus in their analyses almost exclusively on negative party evaluations. This paper clearly distinguishes between negative party identification and evaluation, conceptualizing both concepts coherently within the social identity framework. In addition, new insights are presented by conceptualizing and operationalizing negative party identifications as out-group perceptions of political parties (based on new German data from 2013). The …
ASV un Pakistānas sadarbība terorisma apkarošanā (2001-2014)
2015
ASV un Pakistānas sadarbība terorisma apkarošanā, sniedz ārkārtīgi būtisku informāciju gan attiecībā uz sasniegto pretterorisma jomā, gan attiecībā uz iespējamajiem trūkumiem pretterorisma stratēģijās. Lai gan abu valstu attiecības raksturo abpusēja neuzticēšanās, ASV vadītā pretterorisma cīņa būtu neiespējama bez Pakistānas kā reģiona sabiedrotā. Šobrīd ir skaidrs, ka abu valstu sadarbībā nav sasniegti cerētie rezultātus, bet lai identificētu sadarbības neizdošanās iemeslus ir nepieciešama padziļināta pretterorisma sadarbības izpēte. Lai izvērtētu sadarbību pretterorisma centienos, darba ietvaros tiek aplūkoti abu valstu īstenotie pretterorisma pasākumi, kā arī analizētas pretterorisma pol…
Measuring the wastewater treatment plants productivity change: Comparison of the Luenberger and Luenberger-Hicks-Moorsteen Productivity Indicators
2019
Abstract It is essential to assess the productivity of wastewater treatment plants (WWTPs) to improve their economic and technical performance over time. In doing so, reliable indexes should be used to avoid biased conclusions leading to unsuccessful policy and managerial measures. Ratio-based indexes are typically employed, but are infeasible when any of the variables are equal or close to zero. To overcome this limitation, this paper presents the innovative approach of applying and comparing two difference-based productivity indicators, Luenberger (LPI) and Luenberger-Hicks-Moorsteen (LHMPI), to evaluate how productivity changes in a sample of WWTPs. Because the LHMPI is an additively com…
The Olt River pollution monitoring, using spatial analysis, analityc hierarchy process and technique for order preference by similarity methods
2016
Abstract Environmental pollution is one of the most serious problems of the contemporary world. Chemical industry is one of the major sources of environmental pollutants. Human knowledge and experience is currently focused on the use of assessment methods and techniques before and during the onset of such activities. For instance, it is common to consider the integration of multiple constraining factors and also, taking into account their high complexity and the application of one of the various techniques of Multi-Criteria Decision Making. The purpose of this study is to determine the location of the least and most polluted areas from several sampling points on the Olt River, in Romania. I…
Improving the prediction of air pollution peak episodes generated by urban transport networks
2016
Abstract This paper illustrates the early results of ongoing research developing novel methods to analyse and simulate the relationship between trasport-related air pollutant concentrations and easily accessible explanatory variables. The final scope is to integrate the new models in traditional traffic management support systems for a sustainable mobility of road vehicles in urban areas. This first stage concerns the relationship between the hourly mean concentration of nitrogen dioxide (NO2) and explanatory factors reflecting the NO2 mean level one hour back, along with traffic and weather conditions. Particular attention is given to the prediction of pollution peaks, defined as exceedanc…
A note on cooperative versus non-cooperative strategies in international pollution control
2002
Abstract In this note, we evaluate the scope of Dockner and Long’s [Journal of Environment Economics and Management 24 (1993) 13] conclusion on the efficiency of the non-cooperative outcome in a differential game of international pollution control. We also complete the study of the different equilibria the differential game can present. Our results show that their conclusion requires that the initial value of the stock of pollution be higher than the Pareto-efficient pollution stock so that the equilibrium path of emissions involves a decreasing stock of pollution. Our results also show that the application of the procedure proposed by Tsutsui and Mino [Journal of Economic Theory 52 (1990) …
