This study sheds new light on the different characteristics of social networks for COVID-19 in European regions. This study explores six countries (the United Kingdom, Spain, Italy, Germany, France, and Sweden) by employing social network analysis for Twitter. First, this study finds that European countries show different characteristics for social networks with regard to COVID-19. For example, the UK has only national key players, France shows a majority of national key players, and other countries have all global key players. Donald Trump played an important role in the social networks of Italy, Germany and Sweden while he was the US president. Second, European countries demonstrate different social networks for groups. For example, the UK shows the most active communications across groups, whereas Germany shows the least communication networks across groups. Lastly, European countries reveal highly different interests regarding COVID-19. For example, the UK is more interested in the epidemic and vaccines, Germany focuses on schools and studies, and Sweden cares more about herd immunity and lockdown.

The article is concerned with analysing the key challenges afflicting the world order. The coronavirus pandemic has hit the entire world order, and only now is humankind beginning to realize its far-reaching consequences. An analysis of expert opinions allows us to conclude that, in the near future, not much of the global balance of power will change, although tensions will rise among the world powers regarding leadership and ‘survival’ in terms of the political and economic crisis of the world system caused by the pandemic. The research results can be used to reinforce the line of international and foreign policy activities, as well as be used in the development of scientific programmes in the field of challenges and alternatives to globalization.

This article studies the mechanics through which the EU’s relations with China may harm its values and institutions, providing specific examples that precisely illustrate the Chinese Communist Party’s malign influence in Europe. It also intends to reflect on the extent to which the two distinct political and economic models are compatible with the preservation of a liberal international order. Accordingly, we aim to assess whether the EU has the capacity to counteract China’s sharp power, highlighting concrete policy actions that help strengthen the EU’s position while also identifying persisting shortcomings. It is argued that the EU has considerable economic deterrence to push China into respecting global defined rules and arrangements. Indeed, recent reforms, such as the investment screening mechanism and the global sanctions regime, were an important step towards the affirmation of an EU committed to its values. However, the unanimity requirement in the Common Foreign and Security Policy’s decision-making will likely remain a relevant obstacle for a coherent and efficient EU’s external action.

Turkey’s inclusion in the Belt and Road Initiative in 2015 has raised the expectations of Turkish businesses and government concerning growth-generating investment from China. Existing studies on Chinese investments in Turkey lack sufficient data on the volume of investment, types of firms, and sectoral composition. Based on a novel dataset of Chinese investments in Turkey, this article contributes to filling this gap. We show that although Chinese investment in Turkey has increased considerably in recent years, it remains quite modest compared with investments from the West. Moreover, despite the expanding activities of Chinese technology companies, more than half of Chinese investment in Turkey consists of low value-added manufacturing, extraction of raw materials, and marketing of Chinese products. Overall, the developmental potential of Chinese investment in Turkey has not been radically different from other countries’ investments.

Scientific fraud still lacks a precise, universally accepted definition: the borders between unambiguously established fraud, errors, misconduct are uncertain: this frequently complicates decisions on whether or not cases of questionable behaviour can be classified as true fraud. In this article we have listed the behaviours which establish that true fraud has occurred. The most important is undoubtedly the intentionality of the behaviour, aimed at creating fictitious support of a theory or of a hypothesis. The fraudulent behaviour must have violated the standards of the time in which it occurred: this is an important point, as these standards may have been different in different times. Also important is the fact that the assessment of the seriousness of suspected cases is incremental: it goes from simple misconduct cases that would border on negligence, to cases of evident fraud, e.g. the fabrication or falsification of data or results, and/or the appropriation (plagiarism) of another person’s ideas or data without giving appropriate credit. In recent times, scientific fraud has become widespread, but it was known in the distant past as well: it has involved scientists who are real icons in the history of science. This article analyses the most important cases, dissecting with great attention the particular aspects of the accusations that had been levelled at them. With one exception, it clears them all of the accusations.

Scientific fraud has increased dramatically in recent times. The main reason has been the exponential increase of the number of researchers, that has greatly exceeded the increase in available resources. This has generated a situation of extreme competition that has dramatically increased the tendency to commit FFP acts. In comparison with the situation in the (distant) past, described in the accompanying contribution (Part I), in which scientific misconduct as a rule concerned research on themes of great significance, today the misconduct generally concerns petty fraudulent acts meant to give the fraudster personal advantages that are frequently illusory. Other factors, more technical in nature, are also having roles in today’s great increase of misconduct cases. Important among them are the ease with which they are now discovered thanks to impressive technological advances in their detection, and the appearance and rapid proliferation of open access predatory journals which do not follow the established peer review publication rules. Cases that deal with themes of great general significance do still occur, and some are examined in this article. At variance with those analysed in Part I they are now rapidly solved by the technical resources available today.

Numerous cases of thesis plagiarism by senior public officials in many European countries have attracted significant public attention in recent years. Such different cases, however, have had different political and legal consequences. This article elucidates some of the cases through the examples of Slovakia and the Czech Republic. Based on the theory of political accountability, it is clarified that the reactions of politicians to the exposure of their plagiarism cases were fundamentally different. Almost no common pattern of reactions can be found in the two countries. It is explained that the only solution in both countries was to adopt legislation allowing subsequent withdrawal of a university degree once acquired.
