Alberi e pavimentazioni

La presentazione illustrer\ue0 gli effetti di una sperimentazione in corso dal 2011 finalizzata a studiare gli effetti di diverse tipologie di pavimentazioni sulla crescita e la fisiologia di due specie arboree, oltre che su alcuni parametri fisici del suolo. Verranno illustrate le principali problematiche derivanti dall'impermeabilizzazione del suolo e possibili metodo per porvi rimedio, tra cui pavimentazioni alternative e il verde urbano. Infine, sar\ue0 chiarito quali siano gli stress tipici che possono ridurre i servizi ecosistemici degli alberi in ambienti pavimentati

Normative resistance to responsibility to protect in times of emerging multipolarity: the cases of Brazil and Russia

This article assesses the normative resistance to Responsibility to Protect adopted by Brazil and Russia against the backdrop of their international identities and self-assigned roles in a changing global order. Drawing upon the framework of Bloomsfield's norm dynamics role spectrum, it argues that while the ambiguous Russian role regarding this principle represents an example of 'norm antipreneurship', particularities of Brazil's resistance are better grasped by a new category left unaccounted for by this model, which this study portrays as 'contesting entrepreneur'.- (undefined

It’s not the size, it’s the relationship: from ‘small states’ to asymmetry

Debate about the definition of “small state” has produced more fragmentation than consensus, even as the literature has demonstrated its subjects’ roles in joining international organizations propagating norms, executing creative diplomacy, influencing allies, avoiding and joining conflicts, and building peace. However, work on small states has struggled to identify commonalities in these states’ international relations, to cumulate knowledge, or to impact broader IR theory. This paper advocates a changed conceptual and definitional framework. Analysis of “small states” should pivot to examine the dynamics of the asymmetrical relationships in which these states are engaged. Instead of seeking an overall metric for size as the relevant variable—falling victim in a different way Dahl’s “lump-of-power fallacy,” we can recognize the multifaceted, variegated nature of power, whether in war or peacetime
