"Verwundete Orte" in Hettches Nox und Pareis Die Schattenboxerin

[EN] Body and space play a determinant role in the formation of societies, according to the social analyst Richard Sennet. His thesis that the configuration of spaces in history, such as that of the cities, is closely linked to the perception of the own body offers a relevant theorethical approach for the analysis of Nox (1995) by Thomas Hettche and Die Schattenboxerin (1999) by Inka Parei. In both novels bodies are perceived conscientiously by the self as a wounded and exhausted “I”, but also as a rebellious and fighting “self”. Both novels offer a concept of the body as an inadequate and wounded space, which is actually a key procedure to successfully face the similarly unstable geographical, social and political context of Germany after the Fall of the Berlin Wall.

An observer-based vaccination control law for an SEIR epidemic model based on feedback linearization techniques for nonlinear systems

This paper presents a vaccination strategy for fighting against the propagation of epidemic diseases. The disease propagation is described by an SEIR (susceptible plus infected plus infectious plus removed populations) epidemic model. The model takes into account the total population amounts as a refrain for the illness transmission since its increase makes the contacts among susceptible and infected more difficult. The vaccination strategy is based on a continuous-time nonlinear control law synthesised via an exact feedback input-output linearization approach. An observer is incorporated into the control scheme to provide online estimates for the susceptible and infected populations in the case when their values are not available from online measurement but they are necessary to implement the control law. The vaccination control is generated based on the information provided by the observer. The control objective is to asymptotically eradicate the infection from the population so that the removed-by-immunity population asymptotically tracks the whole one without precise knowledge of the partial populations. The model positivity, the eradication of the infection under feedback vaccination laws and the stability properties as well as the asymptotic convergence of the estimation errors to zero as time tends to infinity are investigated.

The outset of mental torture. Through the lens of the Ticking Time Bomb Scenario

No doubt shall be placed when qualifying torture as one of the cruellest crime offences against human beings. It is widely known that the first torture practices go back to the Middle Ages, where torture mechanisms and devices were used as a legitimate means of punishment, extraction of confessions or executions. Brutal techniques such as ‘Judas Cradle’, ‘The Rack’ or the ‘Rat Torture’ were indeed, the ones commonly used. Moreover, some centuries onwards, torture warrants were permitted and authorised by Privy Councils in legislations such as the English one. However, examples like that were the only ones which public accountability was given to, whereas off-the-book practices remained in silence in other countries for long lasting years. Nowadays, in the 21st century, there are innumerable enforced laws and provisions that prohibit the act of torture, to be precise, physical and psychological torture. Nonetheless, not only are these legislations necessary for fighting torture, but also ad hoc courts and specialised committees continuously report the existence of this crime offence.
