Summary A large survey of German and Israeli younger and older adolescents was conducted to reveal their opinions and attitudes towards violence and aggression, their personal engagement in aggressive and violent behaviors in and outside the school environment, their attitudes toward physical activity, their engagement in physical activity, and the linkage between physical activity engagement and conductance of violence and aggression. The findings point out that there are more similarities than differences between German and Israeli adolescents concerning violence and aggression (...) in and outside schools. No linkage between physical activity involvement and the extent of violent and/or aggressive acts is found. The findings pertaining adolescents’ opinions and attitudes toward aggression and violence and their behaviors in and outside school are encouraging. (shrink)

Der Zeichnung kommt im Trecento nicht allein in der Praxis, sondern auch als theoretisches Fundament einer „wissenschaftlich“ akzeptierbaren ars eine zentrale Rolle zu. Sie ist Medium der Bewahrung und Erneuerung, zudem auch unverzichtbares Kommunikationsmittel in den verschiedenen öffentlichen Bau- und Ausstattungsprogrammen zwischen Mailand, Florenz und Siena. An Cennino Cenninis umfassendem Praxishandbuch, dem ‚Libro dell′arte‘, sowie an einigen Beispielen der Zeichenkunst um 1400, lässt sich ablesen, dass disegno nicht allein die lernende Nachahmung und den Naturabzug, sondern auch den Auszug aus den (...) gespeicherten Sinneseindrücken meinen kann. Vor allem aber wird durch Cenninis Rede vom „Zeichen in deinem Kopf“ der graphische Akt zur Metapher der Neugestaltung der memorierten Bilddaten durch die vis imaginativa der Fantasie. Die Spuren dieser dem Werkstattgespräch entnommenen bildkünstlerischen Fachterminologie reichen allerdings weit zurück und lassen sich über Francesco Petrarca, die Dante-Kommentatoren und Dante selbst bis in die Zeit um 1300 verfolgen. Bereits in der ‚Vita Nuova‘ kann Dante mit dem terminus technicus „disegnare“ in komplexer allegorischer Rede die Fantasie als kreative Arbeit mit dem Gedächtnis hervorheben und mit einer solchen intermedialen Brechung wirkungsvoll vom verdeutlichenden Hervorbringen eines deutenden inneren Bildes durch die ekphrastisch gesteigerte literarische Repräsentation sprechen.

Cells mitigate the detrimental consequences of DNA damage on genome stability by attempting high fidelity repair. Homologous recombination templates DNA double‐strand break (DSB) repair on an identical or near identical donor sequence in a process that can in principle access the entire genome. Other physiological processes, such as homolog recognition and pairing during meiosis, also harness the HR machinery using programmed DSBs to physically link homologs and generate crossovers. A consequence of the homology search process by a long nucleoprotein filament (...) is the formation of multi‐invasions (MI), a joint molecule in which the damaged ssDNA has invaded more than one donor molecule. Processing of MI joint molecules can compromise the integrity of both donor sites and lead to their rearrangement. Here, two mechanisms for the generation of rearrangements as a pathological consequence of MI processing are detailed and the potential relevance for non‐allelic homologous recombination discussed. Finally, it is proposed that MI‐induced crossover formation may be a feature of physiological recombination. (shrink)

Dietrich Bonhoeffer's theology has bad a role in the development ofthe Protestant Churches in the GDR which was not at all unimportant. Wolf Krötke has a closer look at the reception of Bonhoeffer in the GDR. He describes Bonhoeffer in wide perspectives. They range from a socialist demand on the one hand up to critical claims against socialism on the other hand. In these perspectives the slogan of »Kirche im Sozialismus« plays a prominent and at the same time (...) problematic role. Krötke's study demands a critical inventary of the Bonhoeffer-reception in the GDR and gives a first and cautious contribution to this analysis. (shrink)

My strategy is to examine a recent trend in philosophical discussions of responsibility, a trend that tries, but I think ultimately fails, to give an acceptable analysis of the conditions of responsibility. It fails due to what at first appear to be deep and irresolvable metaphysical problems. It is here that I suggest that the condition of sanity comes to the rescue. What at first appears to be an impossible requirement for responsibility---the requirement that the responsible agent have created her- (...) or himself---turns out to be the vastly more mundane and non controversial requirement that the responsible agent must, in a fairly standard sense, be sane.

We give a review and critique of jury theorems from a social-epistemology perspective, covering Condorcet’s (1785) classic theorem and several later refinements and departures. We assess the plausibility of the conclusions and premises featuring in jury theorems and evaluate the potential of such theorems to serve as formal arguments for the ‘wisdom of crowds’. In particular, we argue (i) that there is a fundamental tension between voters’ independence and voters’ competence, hence between the two premises of most jury theorems; (ii) (...) that the (asymptotic) conclusion that ‘huge groups are infallible’, reached by many jury theorems, is an artifact of unjustified premises; and (iii) that the (nonasymptotic) conclusion that ‘larger groups are more reliable’, also reached by many jury theorems, is not an artifact and should be regarded as the more adequate formal rendition of the ‘wisdom of crowds’.

This analysis investigates whether solidarity is an appropriate concept for thinking about justifications for a just distribution of bioethical goods in the international arena. This will be explored by looking at the national origins of the idea of justifying solidarity in the form of the health care that welfare states offer. Following that, ‘life’ and ‘health’ will be placed within a philosophical context by focusing on the main arguments of John Rawls and Amartya Sen and the role of solidarity in (...) these two theories of justice will be analysed. It will be shown that these theories assume that solidarity is not a prerequisite for just international structures. Finally, the possibility will be discussed, that there is a degree of uncertainty surrounding justifications for fair distribution in the international context that can result when the concepts of solidarity and justice are handled imprecisely.

Judgment-aggregation theory has always focused on the attainment of rational collective judgments. But so far, rationality has been understood in static terms: as coherence of judgments at a given time, defined as consistency, completeness, and/or deductive closure. This paper asks whether collective judgments can be dynamically rational, so that they change rationally in response to new information. Formally, a judgment aggregation rule is dynamically rational with respect to a given revision operator if, whenever all individuals revise their judgments in light (...) of some information (a learnt proposition), then the new aggregate judgments are the old ones revised in light of this information, i.e., aggregation and revision commute. We prove an impossibility theorem: if the propositions on the agenda are non-trivially connected, no judgment aggregation rule with standard properties is dynamically rational with respect to any revision operator satisfying some basic conditions on revision. Our theorem is the dynamic-rationality counterpart of some well-known impossibility theorems for static rationality. We also explore how dynamic rationality might be achieved by relaxing some of the conditions on the aggregation rule and/or the revision operator. Notably, premise-based aggregation rules are dynamically rational with respect to so-called premise-based revision operators. (shrink)

Democratic decision-making is often defended on grounds of the ‘wisdom of crowds’: decisions are more likely to be correct if they are based on many independent opinions, so a typical argument in social epistemology. But what does it mean to have independent opinions? Opinions can be probabilistically dependent even if individuals form their opinion in causal isolation from each other. We distinguish four probabilistic notions of opinion independence. Which of them holds depends on how individuals are causally affected by environmental (...) factors such as commonly perceived evidence. In a general theorem, we identify causal conditions guaranteeing each kind of opinion independence. These results have implications for whether and how ‘wisdom of crowds’ arguments are possible, and how truth-conducive institutions can be designed. (shrink)

Bringing these two emergent areas of thought into direct conversation in Before the Law, Cary Wolfe fosters a new discussion about the status of nonhuman animals and the shared plight of humans and animals under biopolitics.

Condorcet's famous jury theorem reaches an optimistic conclusion on the correctness of majority decisions, based on two controversial premises about voters: they are competent and vote independently, in a technical sense. I carefully analyse these premises and show that: whether a premise is justi…ed depends on the notion of probability considered; none of the notions renders both premises simultaneously justi…ed. Under the perhaps most interesting notions, the independence assumption should be weakened.

In the Transcendental Aesthetic (TA), Kant is typically held to make negative assertations about “things in themselves,” namely that they are not spatial or temporal. These negative assertions stand behind the “neglected alternative” problem for Kant’s transcendental idealism. According to this problem, Kant may be entitled to assert that spatio-temporality is a subjective element of our cognition, but he cannot rule out that it may also be a feature of the objective world. In this paper, I show in a new (...) way how Kant’s view (focusing on his conclusions about space) is not subject to this objection, by showing that he does not make the denial about mind-independent reality that he is typically held to make. The argument develops consequences of a new reading of Kant’s expression “an sich selbst” (‘in itself’; ‘in themselves’). I argue that “an sich selbst” or “per se” has a special, judgment-level role, so that this expression does not form new noun-terms adjectivally. It follows that the conceptual unit of Kant’s “Conclusions” in the TA is simply “things” (Dinge), since “things in themselves” is not a nominal expression; Kant adopts the Wolffian ontological use of “thing” as the basic kind-term for any existent. The arguments that things per se are not in space are arguments that space cannot be a necessary property or relations of things as a kind. I show that this does not involve the positive claim about mind-independent reality that inspires the neglected alternative objection. (shrink)

We present an abstract model of rationality that focuses on structural properties of attitudes. Rationality requires coherence between your attitudes, such as your beliefs, values, and intentions. We define three 'logical' conditions on attitudes: consistency, completeness, and closedness. They parallel the familiar logical conditions on beliefs, but contrast with standard rationality conditions like preference transitivity. We establish a formal correspondence between our logical conditions and standard rationality conditions. Addressing John Broome's programme 'rationality through reasoning', we formally characterize how you can (...) (not) become more logical by reasoning. Our analysis connects rationality with logic, and enables logical talk about multi-attitude psychology. (shrink)

In solving judgment aggregation problems, groups often face constraints. Many decision problems can be modelled in terms the acceptance or rejection of certain propositions in a language, and constraints as propositions that the decisions should be consistent with. For example, court judgments in breach-of-contract cases should be consistent with the constraint that action and obligation are necessary and sufficient for liability; judgments on how to rank several options in an order of preference with the constraint of transitivity; and judgments on (...) budget items with budgetary constraints. Often more or less demanding constraints on decisions are imaginable. For instance, in preference ranking problems, the transitivity constraint is often contrasted with the weaker acyclicity constraint. In this paper, we make constraints explicit in judgment aggregation by relativizing the rationality conditions of consistency and deductive closure to a constraint set, whose variation yields more or less strong notions of rationality. We review several general results on judgment aggregation in light of such constraints. (shrink)
