Main Driver

The diffusion of COVID-19 pandemic among Italian Regions has been very uneven. The intensity of measures introduced to contrast its spread also shows a high heterogeneity among local jurisdiction, but this does not correspond, prima facie, with the intensity of the pandemic. What shapes the stringency of responses across different localities? Various factors could be hypothesised to be at play: factors related to the intensity of the pandemic, to the political and ideological orientation of governing authorities, to the models of growth and development characterising regional economic systems, and to the strength of lobbying groups pushing for more or less stringent responses. To address these questions, we elaborate a regional stringency index and analyse (using CART regression trees and other statistical methods) its relationships with some of these factors. The results show that the main driver of stringency (in an inverse way) is the weight of exports on regional GDP, suggesting that economic interests and business power might play an important role in shaping political responses to pandemics.

This chapter introduces agent-based modeling as a methodology to study qualitative change in economic systems. The need to focus on qualitative developments is derived from evolutionary economics, where the quantitative orientation of mainstream economic approaches is strongly criticized. It is shown that agent-based models can cope with the challenges of an evolutionary setting and fulfill the requirements of modeling qualitative change. In particular agent-based models allow a detailed representation of knowledge and the underlying dynamics, which are considered the major driving force of economic growth and development. The chapter also gives an illustrative example of an agent-based model of innovation processes organized in networks of actors.

Negative Phenomena

AbstractIt is not only growth and development that is of value to local, regional and central governments, but also the ability to absorb negative phenomena and the ability to continuously transform socio-economic systems. Resilience strategies thus serve as a response to the more and more frequent and intense natural, social and economic challenges. In some approaches to urban resilience, special attention is paid to activities undertaken by cities to become inclusive, integrated, robust, resourceful, reflective, redundant and flexible. In regional strategies the emphasis is on diversity, dispersion, mutuality and modularity. The aim of the paper is to synthesise selected qualities of resilient cities and regions into a new model of resilience strategy. It assumes that goals at each level of strategy are formulated according to adaptive interpretation of the resilience concept. Development of such model would enable the use of the concept by practitioners responsible for creating development strategies.

Cell and tissue interactions are a basic aspect of eukaryotic growth and development. While cell-to-cell interactions involving recognition and incompatibility have been studied extensively in animals, there is no known antigen-antibody reaction in plants and the recognition mechanisms operating in plant grafts have been virtually neglected.An ultrastructural study of the Sedum telephoides/Solanum pennellii graft was undertaken to define possible mechanisms of plant graft incompatibility. Grafts were surgically dissected from greenhouse grown plants at various times over 1-4 weeks and prepared for EM employing variations in the standard fixation and embedding procedure. Stock and scion adhere within 6 days after grafting. Following progressive cell senescence in both Sedum and Solanum, the graft interface appears as a band of 8-11 crushed cells after 2 weeks (Fig. 1, I). Trapped between the buckled cell walls are densely staining cytoplasmic remnants and residual starch grains, an initial product of wound reactions in plants.
