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)

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 our article, we argue, following Nelson Goodman and Arthur Danto, that in contrast to the essentialist conception of authenticity, it is more fertile to consider authentic patterns not as the inner core of the person, but as a case of metaphorical exemplification. According to our approach, if we accept that authentic style is a metaphorical exemplification, then, based on Richard Rorty’s concepts of language and metaphor, style can be seen as an exaptation or reuse of symbols previously adapted through (...) cultural selection to other specific functions. To support this approach, we proceed as follows. First, using Goodman’s and Danto’s model, we argue that authentic style can best be grasped through metaphorical exemplification. We then show that the metaphorical use of linguistic, pictorial, and other symbols is the result of exaptation. According to our results, the authentic style is the exaptation of symbols previously adapted to culturally selected functions. We then separate authenticity from creativity through the concepts of style and manner—borrowed from Danto—and we point out that whether a particular symbol is authentic or not is not affected by whether creative or mechanical mental processes are responsible for its creation. Finally, we examine the relationship between authenticity and autonomy, and we show that in an environment that promotes autonomous decisions and authentic style, agents that originally generated inauthentic symbols may be able to produce authentic ones.

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.

Das Aequivalenzprinzip wurde von Einstein erst 1907 in Worte gefasst. Er wendete sich 1912 brieflich an W. Wien mit der Bitte, den Unterschied der Schwingungsdauer eines Uranpendels und eines Bleipendels sowie die Proportionalität der trägen und schweren Massen eines Blei- und eines Urangewichts auszumessen, und zwar mit einer Drehwage. Der Brief macht es klar, dass Einstein bei der Aufstellung des Aequivalenzprinzips von dem Eötvös-Versuch nichts wusste, und als es ihm nötig schien, das Prinzip experimentell zu prüfen, hat er den Versuch (...) neuentdeckt.The principle of equivalence was first formulated by Einstein in 1907. In 1912 he turned by letter to W. Wien with the request to measure the difference between the periods of oscillation of pendulums made of uranium and lead, as well as the proportionality of inertial and gravitational masses of a uranium and a lead weight, respectively, namely with a torsion balance. The letter testifies that Einstein was not aware of the Eötvös experiment when he formulated the principle of equivalence and as soon as he needed an experimental test of it, he reinvented the experiment.

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)

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)

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)

Wittgenstein, possibly the most influential philosopher of the twentieth century, is often labelled a Neopositivist, a New-Kantian, even a Sceptic. _Questions on Wittgenstein_, first published in 1988, presents a selection of nine essays investigating a matter of vital philosophical importance: Wittgenstein’s relationship to his Austrian predecessors and peers. The intention throughout is to determine the precise contours of Wittgenstein’s own thought by situating it within its formative context. Although it remains of particular interest to Anglo-Saxon philosophers, special familiarity with Austrian (...) philosophy is required to appreciate the subtle and profound influence which this cultural and philosophical setting had on Wittgenstein’s intellectual development. Professor Haller has spent his career exploring these themes, and is one of the foremost authorities on both Wittgenstein and contemporary Austrian philosophy. Questions on Wittgenstein thus offers a unique insight into the twentieth-century tradition of Austrian philosophy, and its importance for Wittgenstein’s thought. (shrink)

The study's goal was to examine the socially responsible power use in the context of ethical leadership as an explanatory mechanism of the ethical leadership-follower outcomes link. Drawing on the attachment theory (Bowlby, 1969/1982 ), we explored a power-based process model, which assumes that a leader's personal power is an intervening variable in the relationship between ethical leadership and follower outcomes, while incorporating the moderating role of followers' moral identity in this transformation process. The results of a two-wave field study (...) ( N = 235) that surveyed employees and a scenario experiment ( N = 169) fully supported the proposed (moderated) mediation models, as personal power mediated the positive relationship between ethical leadership and a broad range of tested follower outcomes (i.e., leader effectiveness, follower extra effort, organizational commitment, job satisfaction, and work engagement), as well as the interactive effects of ethical leadership and follower moral identity on these follower outcomes. Theoretical and practical implications are discussed. (shrink)
