Multi-hazard, exposure and vulnerability in Italian municipalities
No full textDisaster risk is a function of hazard, exposure and vulnerability. These dimensions may show large heterogeneity also at a very local level. This work uses updated statistics on natural hazards (earthquake, landslide and flood hazards) at a municipality level in Italy in order to tackle the issue of multi-hazard. Through a cluster analysis and a Multi-Hazard Indicator it is possible to disentangle specific and geographically defined hazard patterns. Moreover, the analysis of both exposures and local vulnerabilities suggests that they tend to be linked with hazards. In this respect, Italian inner areas seem to face the most critical situation (and because of the lack of organisation infrastructures), and deserve proper attention. In particular, community resilience (as also promoted by the Sendai Framework) could be enhanced by a proper assessment of local hazards and vulnerabilities
Did Zipf anticipate spatial connectivity structures?
No full textAn avalanche of empirical studies has addressed the validity of the rank-size
rule (or Zipf ’s law) in a multicity context in many countries. Under which conditions (eg,
sample size, spatial scale) this ‘law’ holds remains as yet largely underinvestigated, while
spatial network constellations also deserve more attention. Against this background, we
investigate the relationship between network connectivity and the rank-size rule (or Zipf ’s
law) in an urban economic network constellation. In particular, we address the following
methodological issues: (i) the (aggregate) behavioural foundation underlying the rank-size
rule (Zipf ’s law) in the light of spatial-economic network theories (eg, entropy maximization,
spatial interaction theory); (ii) the nature of the analytical relationship between
social-spatial network analysis and the rank-size rule (Zipf ’s law). We argue that the ranksize
rule is compatible with conventional economic foundations of spatial network models.
We test the sensitivity of rank-size rules for changes in scale, functional forms, time periods,
and connectivity structures. Our application uses an extensive spatiotemporal panel
database on the evolution of the urban population in Germany. We test the relevance of
the rank-size rule (Zipf ’s law), and—in parallel—the related ‘socioeconomic’ connectivity
in these urban networks. In particular, we will show that Zipf ’s law (ie, with the rank-size
coefficient equal to 1) is only valid under particular conditions of the sample size
Introduction to The Creative Class Revisited: New Analytical Advances
Full text linkIn this introductory chapter, we contextualize and briefly describe the intellectual contributions of the different chapters in this book. Following this chapter, which comprises Part I of the book, there are eleven chapters and each of these chapters addresses a particular research question or a set of questions about the creative class. Part II of this book consists of two chapters and this part focuses on alternate conceptual approaches to the creative class. Part III also contains two chapters and this part concentrates on analytics. Part IV consists of five chapters and this part sheds light on a variety of regional perspectives on the creative class. Finally, the two chapters that make up part V takes a retrospective and a prospective look at research on the creative class. In the concluding section of the present chapter, we offer some reflections on the cornerstones of creative class theory as advocated by Richard Florida two decades ago
Valuing urban cultural heritage
No full textThe evaluation of cultural assets is a research activity that finds its roots in environmental evaluation. The latter aims to assess from an individual or societal perspective the economic meaning of environmental goods (or a degradation of such goods). Cultural heritage forms a particular subset of environmental goods with specific characteristics in terms of uniqueness and historical orientation. Nevertheless, various general principles from environmental valuation apply also to cultural goods, as they have similar attributes: scarcity, non-priced nature as a result of externalities, and site specificity (see, for example, Carruthers and Mundy 2006). The principles of environmental evaluation can be found in the theory of hedonic prices and implicit markets advocated decades ago by Rosen (1974). Ever since then, a great effort has been made to operationalise evaluation concepts and to extend the domain of valuation by developing adjusted new methods (for example, travel costs methods, and survey-based methods such as contingent valuation and conjoint methods). After significant progress in disciplines such as ecological economics and environmental economics (see, for example, van den Bergh et al. 2006), the question arises whether the evaluation of cultural heritage has a sufficiently strong basis
Space and knowledge spillovers in European regions: the impact of different forms of proximity on spatial knowledge diffusion
Full text linkUsually, knowledge spillovers (KS) are related to geographic proximity. In the present study, we measure KS on the basis of different proximity matrices, focusing on the relational, social, cognitive and technological preconditions for knowledge diffusion. In the light of previous studies on KS, we examine: (i) which types of proximity enhance or hamper knowledge flows, and (ii) whether local absorptive capacity favour such flows. Our results indicate that KS across European NUTS2 regions measured through geographic, relational, social, cognitive and technological proximity channels increase with local absorptive capacity. This finding points towards the emergence of large clusters of regions (absorptive capacity clubs) where relational, cognitive, social and technological proximity lock-in maximizes the returns to local investment in R&D
