    "Nella presente nota è descritta Typhloreicheia flaviae n. sp., scoperta nella Grotta. di Istirzili N° 50 Sa\/NU, 507 m s.l.m. (Sardegna centro-orientale, Supramonte di Baunei,. Ogliastra). La nuova specie è affine a T. casalei Magrini, Marcia & Onnis, 2011, nota di. una grotta del Supramonte di Urzulei, ma se ne differenzia per numerosi caratteri indicati. nel testo e illustrati nelle figure; in particolare: dimensioni nettamente minori, corpo più. depresso, tegumenti meno lucidi, pronoto più ristretto alla base, lobo mediano dell’edeago. con apice più appuntito in visione laterale e meno inclinato ventralmente, in visione ventrale. più dritto e simmetrico, lamella copulatrice con apice conformato diversamente. La. nuova specie non presenta caratteri adattativi alla vita ipogea particolarmente evidenti, ma. è complessivamente simile ad altri taxa, endogei o tipici dell’MSS, reperiti recentemente. in cavità della Sardegna orientale e meridionale: T. carlonnisi Magrini, Marcia & Casale,. 2011, T. casalei Magrini, Marcia & Onnis, 2011 e T. grafittii Magrini, Onnis, Casale &. Marcia, 2012. Sono inoltre riportate alcune note addizionali sulla distribuzione di Typhloreicheia. bulirschi Magrini & Bastianini, 2011 nella Sardegna meridionale.

    Urban Growth Drivers and Spatial Inequalities: Europe - a case with geographically sticky people

    No full text
    We try to combine theory with empirical analysis to investigate the drivers of spatial growth processes, welfare and disparities in a context in which people are markedly immobile. Drawing on two of our recent papers (Cheshire and Magrini, 2006 and 2008), we review the evidence on the drivers of differential urban growth in the EU both in terms of population and output growth. The main conclusion from our findings is that one cannot reasonably maintain the assumption of full spatial equilibrium in a European context. This has a number of wider implications. It suggests that i. differences in real incomes in Europe - and more generally where populations are relatively immobile - are likely to persist and indicate real differences in welfare; ii. there is no evidence of a unified European urban system but rather of a set of national systems; iii. there are significant but theoretically consistent, differences in the drivers of population compared to economic growth

    Recent Developments in Thermophysical Properties Estimation of Insulating Materials from Transient Tests

    No full text
    The aim of this work is to present some recent developments in the identification technique of thermophysical properties of insulating materials from transient conductive experiments. The non linear, time varying, inverse heat conduction problem is solved by using a suitable version of the Kalman filter. This last is one of the more general and powerful stochastic methodology available in the field of parameter estimation. Several transient experiments performed with the European standard reference for thermal conductivity of insulators (resin bonded glass fiber board BCR 64) have shown that the confidence bound of the reconstructed thermophysical properties is comparable to that given by standard methods

    Raising Urban Productivity or Attracting People? Different Causes, Different Consequences

    No full text
    This paper investigates growth differences in the urban system of the EU12 over the last decades of the 20th Century. Models in which growth of real GDP p.c. and rates of population growth are the dependent variables are compared. This suggests that it makes sense to model GDP growth in a European context. The analysis supports the conclusion that systems of urban governance are significantly related to economic growth, as is the distribution of highly skilled human capital and R&D activity. In addition, evidence is found supporting the conclusion that integration shocks in the EU favour core areas but when all else is controlled for peripheral regions experienced a systematic positive growth differential. Careful testing for spatial dependence reveals that national borders are significant barriers to adjustment but we can resolve such problems by including a set of variables designed to reflect spatial economic adjustment mechanisms where cities are densely packed so their economies interact. Models of population growth show some similar results but interesting and revealing differences. Strong evidence is found that there are substantial national border effects impeding the emergence of a full spatial equilibrium across the EU’s urban system. Better climate is the single most significant variable but only when expressed relative to the national (not EU) mean. As with economic growth, there are significant national border effects in patterns of spatial dependence. Concentrations of human capital and R&D, however are if anything negatively associated with attracting population – a finding which parallels the finding that a better climate relative to the national mean is associated with slower rather than faster growth of real GDP per capita.growth; cities; local public goods; human capital; convergence; territorial competition

    Analysing Growth and Distribution Dynamics - Isolating Divergence Factors

    No full text
    This paper analyses the factors driving convergence and divergence processes in the growth dynamics of European urban regions over the period 1978 to 1994. To achieve this, we develop a two-stage procedure. First, viewing growth of real GDP per capita as a multivariate process, a fully specified growth model is estimated assessing growth dynamics and the role of a rich set of variables. In particular, as noted elsewhere (Cheshire and Magrini, 2005), evidence is found which is supportive of a spatial adaptation of the endogenous growth model, with human capital related variables having a highly significant role in explaining growth differences. The second stage then uses a ‘distribution dynamics’ approach to evaluate the contribution of individual growth factors to convergence dynamics. More specifically, regression results are used to simulate alternative end period incomes which, via the estimation of stochastic kernels, enable us to isolate the role of selected variables in shaping the dynamics of the cross-sectional distribution of per capita income. This analysis suggests that the most important factor determining the form of FUR growth and convergence dynamics observed from 1978 to 1994 was the differing distribution of human capital. These results are compared with the results using the Markov Chain approach and it is found both techniques lead to similar conclusions.
