Hypothesis-driven approaches identified important characteristics that differentiate violent from non-violent radicals. However, they produced a mosaic of explanations as they investigated a restricted number of preselected variables. Here we analyzed without a priory assumption all the variables of the “Profiles of Individual Radicalization in the United States” database by a machine learning approach. Out of the 79 variables considered, 19 proved critical, and predicted the emergence of violence with an accuracy of 86.3%. Typically, violent extremists came from criminal but not (...) radical backgrounds and were radicalized in late stages of their life. They were followers in terrorist groups, sought training, and were radicalized by social media. They belonged to low social strata and had problematic social relations. By contrast, non-violent but still criminal extremists were characterized by a family tradition of radicalism without having criminal backgrounds, belonged to higher social strata, were leaders in terrorist organizations, and backed terrorism by supporting activities. Violence was also promoted by anti-gay, Sunni Islam and Far Right, and hindered by Far Left, Anti-abortion, Animal Rights and Environment ideologies. Critical characteristics were used to elaborate a risk-matrix, which may be used to predict violence risk at individual level. (shrink)

We relax the assumption that priors are common knowledge, in the standard model of games of incomplete information. We make the realistic assumption that the players are boundedly rational: they base their actions on finite-order belief hierarchies. When the different layers of beliefs are independent of each other, we can retain Harsányi's type-space, and we can define straightforward generalizations of Bayesian Nash Equilibrium and Rationalizability in our context. Since neither of these concepts is quite satisfactory, we propose a hybrid concept, (...) Mirage Equilibrium, providing us with a practical tool to work with inconsistent belief hierarchies. When the different layers of beliefs are correlated, we must enlarge the type-space to include the parametric beliefs. This presents us with the difficulty of the inherent openness of finite belief subspaces. Appealing to bounded rationality once more, we posit that the players believe that their opponent holds a belief hierarchy one layer shorter than they do and we provide alternative generalizations of BNE and Rationalizability. Finally, we show that, when beliefs are degenerate point beliefs, the definition of Mirage Equilibrium coincides with that of the generalized BNE. (shrink)

Enlightenment thought and its contemporary followers usually support two contradictory principles simultaneously. The first is universality. Truth is universal because it is truth for all. Claims to universality are made in logic and science, but also in areas that are culturally or politically controversial. Recently, universalism has become a key term to express a fundamental critique of identity politics. For much of European history, Christianity provided such a universal truth. But with the decline of its cultural hegemony and the rise (...) of particular nation-states, conflicting truth claims became weapons in violent conflicts, leading Hobbes to argue that dangerous truth claims must be neutralized by robust political power. In the eighteenth century, rationalism became more optimistic, interpreting universalism as cosmopolitanism based on universal reason and progress through history. The second principle is historicism, which is the self-reflexive look at the historical origins of universal claims and theories. Historicism emerged in the nineteenth century as a response to the application of rationalism to history. It challenged the universal claims of the French Revolution, emphasizing instead the unique value of each historical entity. This revealed a fundamental paradox: when universalism becomes self-reflexive, it recognizes that it has non-universal historical origins, thereby undermining itself. After the devastation of World War II and the Holocaust, the Universal Declaration of Human Rights (1948) represented a significant effort toward a new universalism. It sought to establish human rights as universal principles for the emerging world order. But history repeated itself: Historicism once again weakened confidence in human rights. The enemies of human rights take advantage of this weakness. We therefore have to live with the paradox that universalism is necessary because humanity shares a single world, but that historical self-reflection is also unavoidable. In other words, the Enlightenment principle of universalism must accept historicism as an integral part of itself. (shrink)

Examining the naturalist and normativist concepts of health and disease this article starts with analysing the view of C. Boorse. It rejects Boorse's account of health as species-typical functioning, giving a critique of his view based on evolutionary theory of contemporary biology. Then it gives a short overview of the normativist theories of health, which can be objectivist and subjectivist theories. Rejecting the objectivist theories as philosophically untenable, it turns to the subjectivist theories of Gert and Culver, and to the (...) view of Nordenfelt. These theories give quite a good subjectivist account of health and disease, but they do not pay enough attention to the notion of the environment, without which it is impossible to define health and disease. Starting with their definitions but introducing the notion of “reasonable social norms”, the article arrives at the following definition of health: The healthier a physical or mental characteristic, process, reaction is, the more it makes it possible for the individual to adapt to reasonable social norms without pain and suffering, and the longer, and happier a life it will be able to ensure him in that society.

Bódog (Felix) Somló is the most reputable representative of Hungarian legal philosophy at the last turn of the century, whose ouevre greatly contributed to the establishment of the neo-Kantian legal philosophy, the dominant trend preaviling in Central Europe at the time, a development that eventually resulted in modernising the legal scholarship and theoretical thought in law in Hungary. Hungarian jurisprudence can be proud of the fact that Bódog Somló, besides Rudolf Stammler, Gustav Radbruch, Hans Kelsen and Alfred Verdross is regarded (...) as a great representative of European neo-Kantian philosophy of law.

The current use of citation-based metrics to evaluate the research output of individual researchers is highly discriminatory because they are uniformly applied to authors of single-author articles as well as contributors of multi-author papers. In the latter case, these quantitative measures are counted, as if each contributor were the single author of the full article. In this way, each and every contributor is assigned the full impact-factor score and all the citations that the article has received. This has a multiplication (...) effect on each contributor's citation-based evaluative metrics of multi-author articles, because the more contributors an article has, the more undeserved credit is assigned to each of them. In this paper, I argue that this unfair system could be made fairer by requesting the contributors of multi-author articles to describe the nature of their contribution, and to assign a numerical value to their degree of relative contribution. In this way, we could create a contribution-specific index of each contributor for each citation metric. This would be a strong disincentive against honorary authorship and publication cartels, because it would transform the current win-win strategy of accepting honorary authors in the byline into a zero-sum game for each contributor.

This paper invokes the conceptual framework of Bourdieu to analyse the mechanisms, which help to maintain inappropriate authorship practices and the functions these practices may serve. Bourdieu’s social theory with its emphasis on mechanisms of domination can be applied to the academic field, too, where competition is omnipresent, control mechanisms of authorship are loose, and the result of performance assessment can be a matter of symbolic life and death for the researchers. This results in a problem of game-theoretic nature, where (...) researchers’ behaviour will be determined more by the logic of competition, than by individual character or motives. From this follows that changing this practice requires institutionalized mechanisms, and change cannot be expected from simply appealing to researchers’ individual conscience. The article aims at showing that academic capital is translated into honorary authorship. With little control, undetected honorary authorship gives the appearance of possessing intellectual capital. In this way a dominant position is made to be seen as natural result of intellectual ability or scientific merit, which makes it more acceptable to those in dominated positions. The final conclusion of this paper is that undemocratic authorship decisions and authorship based performance assessment together are a form of symbolic violence. (shrink)

In this commentary I discuss the role of types of knowledge and conceptual structures in lexical representation, revealing the explanatory potential of frame-based knowledge. Although frame-based lexical semantics is not alien to the theoretical model outlined in Jackendoff's conceptual semantics, testing its relevance to the analysis of the lexical evidence presented in his book has been left out of consideration.

This commentary asks the reader to examine Pylyshyn's target article and the imagery debate at four levels of analysis – institutional, programmatic, empirical, and individual. It is proposed that the debate follows somewhat generic patterns of discourse at all four levels, but the discourse associated with one side of the debate may or may not be expressible and evaluated in terms of the other. The different sides of the debate might better serve cognitive science if they proceed as separate research (...) programs in their respective sub-disciplines. A more inclusive program could result, however, if the opposing approaches could somehow unite. (shrink)

This article investigates the emergence of the concept of stress in the 1930s and outlines its changing disciplinary and conceptual frames up until 1960. Originally stress was a physiological concept applied to the hormonal regulation of the body under stressful conditions. Correlated closely with chemical research into corticosteroids for more than a decade, the stress concept finally became a topic in cognitive psychology. One reason for this shift of the concept to another discipline was the fact that the hormones previously (...) linked to the stress concept were successfully transferred from laboratory to medical practice and adopted by disciplines such as rheumatology and dermatology. Thus the stress concept was dissociated from its hormonal context and became a handy formula that allowed postindustrial society to conceive of stress as a matter of individual concern. From a physiological phenomenon stress turned into an object of psychological discourse and individual coping strategies. (shrink)

Anderson and Dyck claim that the current trend of almost exclusively using citation-based evaluative metrics to assess the research output of scholars is unsound. I agree with them in this, but I feel that, for practical reasons, this system will not disappear in the near future, so we must concentrate on making it fairer. Both commentators doubt whether numerically expressing each contributor's relative contribution is feasible. I admit that an important precondition for this task is the possibility of an informed, (...) democratic debate among equals about the relative contribution of each contributor to the article. Mechanisms should be established to protect vulnerable researchers in the academic field in the same way as safeguards exist today to protect vulnerable research participants. Theoretically, however, I think that the fair allocation of authorship credit is possible, and much of this task is already being performed routinely when contributors determine the order of their names in the byline, being well aware of the widespread assumption that this order mostly mirrors the order of their relative contributions. All they would have to do as an additional task is to express this order in numbers. If they cannot reach a consensus, they could always choose not to express their relative contribution in numbers, in which case the presumption would be that they contributed equally. My proposal could, at best, make the system fairer and, at worst, not reduce the options that evaluators already have. (shrink)

How different neural crest derivatives differentiate in distinct embryonic locations in the vertebrate embryo is an intriguing issue. Many attempts have been made to understand the underlying mechanism of specific pathway choices made by migrating neural crest cells. In this speculative review we suggest a new mechanism for the regulation of neural crest cell migration patterns in avian and mammalian embryos, based on recent progress in understanding the expression and activity of receptor tyrosine kinases during embryogenesis. Distinct subpopulations of crest‐derived (...) cells express specific receptor tyrosine kinases while residing in a migration staging area. We postulate that the differential expression of receptor tyrosine kinases by specific subpopulations of neural crest cells allows them to respond to localized growth factor ligand activity in the embryo. Thus, the migration pathway taken by neural crest subpopulations is determined by their receptor tyrosine kinase response to the differential localization of their cognate ligand. (shrink)
