A formal approach to reanalysis: The case of a negative counterfactual marker

This paper proposes a formal definition of reanalysis, while emphasizing the importance of the distinction between two different kinds of reanalysis: those in which the change is confined to the grammatical level, and those in which it is confined to the semantic level. After tracing the history of a negative counterfactual conditional marker in Hebrew and Aramaic which underwent both syntactic and semantic reanalyses, the paper assesses the concept of reanalysis with focus on the following questions: Is reanalysis a single, clearly-defined phenomenon, and if so, what is its nature? Is it merely a descriptive label for a certain observable state of affairs, or does it explain diachronic changes? Alternatively, perhaps it is a theoretical constraint, a theoretical requirement that linguistic change must be associated with specific environments where reanalysis can take place? A detailed analysis of the marker and its evolution yields the following broad hypothesis: Reanalysis of a linguistic form does not change the truth conditions of the proposition that contains it, regardless of whether the reanalysis is on the grammatical level or on the semantic level.

Terrorism prevention with reelection concerns and valence competition

In recent decades, fear of terrorism has increased among voters in liberal democracies. In response, governments have adopted counterterrorist measures that curtail civil liberties, at times prompting allegations that political expediency underlies such measures. I study politicians’ strategic design of counterterrorist policies in a model of valence competition under threat of terrorism. The incumbent chooses a counterterrorist strategy that combines observable (state of emergency) and unobservable (effort) actions. In equilibrium, emergencies and terrorist attacks become endogenously informative about valence. The low-valence incumbent underprovides effort relative to the high-valence incumbent, and at times declares a state of emergency in the absence of a terrorist threat. Increasing voters’ information about the incumbent’s valence improves politician selection, but at the expense of a higher incidence of unwarranted emergencies and, under some conditions, terrorist attacks.

Part 2 The Post-Cold War Era (1990–2000), 42 The US Airstrike Against the Iraqi Intelligence Headquarters—1993

This contribution analyses the normative implications of the US raid against the headquarters of the Iraqi Intelligence Service in 1993 in reaction to a foiled assassination attempt against former President Bush. It examines the legality of the operation, its precedential value and its evolutive potential regarding the regime on the ius contra bellum and specifically the right to self-defence. After dissecting the multiple contentious dimensions of the US claim of justification, the article concludes that the raid constituted an illegal ‘armed reprisal’. In light of observable state practice, its precedent-setting nature should not be overstated. However, albeit qualified as an ‘one-off incident’ the US raid did not leave the prohibition on the use of force and the contemporary discourse surrounding it untouched. Hence, it appears essential to demystify its frequently asserted evolutive potential particularly regarding the temporal limitations of Article 51 UN Charter to which this article is dedicated.

Continuum theory of fibrous tissue damage mechanics using bond kinetics: application to cartilage tissue engineering

This study presents a damage mechanics framework that employs observable state variables to describe damage in isotropic or anisotropic fibrous tissues. In this mixture theory framework, damage is tracked by the mass fraction of bonds that have broken. Anisotropic damage is subsumed in the assumption that multiple bond species may coexist in a material, each having its own damage behaviour. This approach recovers the classical damage mechanics formulation for isotropic materials, but does not appeal to a tensorial damage measure for anisotropic materials. In contrast with the classical approach, the use of observable state variables for damage allows direct comparison of model predictions to experimental damage measures, such as biochemical assays or Raman spectroscopy. Investigations of damage in discrete fibre distributions demonstrate that the resilience to damage increases with the number of fibre bundles; idealizing fibrous tissues using continuous fibre distribution models precludes the modelling of damage. This damage framework was used to test and validate the hypothesis that growth of cartilage constructs can lead to damage of the synthesized collagen matrix due to excessive swelling caused by synthesized glycosaminoglycans. Therefore, alternative strategies must be implemented in tissue engineering studies to prevent collagen damage during the growth process.

THE OBSERVABLE-STATE MODEL AND NONRENORMALIZABLE THEORIES

The aim of this work is to apply the observable-state model for the quantum field theory of a ϕn self-interaction. We show how to obtain finite values for the two-point and n-point correlation functions without introducing counterterms in the Lagrangian. Also, we show how to obtain the renormalization group equation for the mass and the coupling constant. Finally, we find the dependence of the coupling constant with the energy scale and we discuss the validity of the observable-state model in terms of the projection procedure.
