The Red Swamp Crayfish Procambarus Clarkii (the Louisiana Crayfish) as a Particular Scavenger on a Human Corpse

An 85-year-old man was found deceased floating in an irrigation ditch 18 days after his disappearance. During crime scene investigation, specimens of the red swamp crayfish Procambarus clarkii were found in proximity of the body. The feeding activity of these nonendemic crayfishes contributed to the formation of specific injuries on the body and in the production of a large substance defects inside the corpse. The aim of this paper was to illustrate the scavenging activity of P. clarkii on a human body and highlight the potential postmortem artefacts caused by this species. This is the first report on a real case of postmortem injuries produced by P. clarkii crayfishes on a submerged human body. So far, crustaceans are not considered useful for the estimation of the minimum postmortem interval. However, the important modifications on the corpses deriving from the activity of these animals should be kept in consideration.     

“One,none, and a hundred thousand” recipes for a robust response to turbulence

Turbulence appears to be a “new normal” in current societies, and public organizations need to learn how to react and adapt to it. Scholars agree on the need for robust actions to respond to turbulence. Through a qualitative comparative analysis performed on the vaccination campaigns of all 20 Italian regions, our paper explores whether different and alternative models of robustness may exist to cope with turbulence. Results shed light on three alternative models featuring static, hybrid, and dynamic robustness. They also highlight that robust governance appears to involve a capacity to learn, and to employ this learning as circumstances demand.

Validity and Defeasibility in the Legal Domain

In jurisprudential literature, the adjective ‘defeasible’ appears as a predicate of many terms: concepts, laws, rules, reasoning, justification, proof, and so on. In this paper, we analyze the effects of some versions of the thesis of the defeasibility of legal norms on the reconstruction of the notion of legal validity. We analyze some possible justifications of this thesis considered as a claim concerning validity, and enquire into two possible sets of problems related to the defeasibility of the criteria of identification of a legal system. We also provide a formalization of some options regarding defeasible criteria of identification, which can be used as a tool for meta-jurisprudential analysis. Finally, the thesis according to which defeasibility is better conceived of as a feature of legal application is examined and questioned.
