Economy and society in Europe: A relationship in crisis
No full text'Improving our understanding of how economy and society interrelate in Europe is of paramount importance. The rigorous and thought-provoking analyses about the interaction between markets and the institutions of society contained in this book undoubtedly represent an excellent example of how this improvement can be achieved, especially in these times of crisis.' - Andrés Rodríguez-Pose, London School of Economics, UK. © Luigi Burroni, Maarten Keune and Guglielmo Meardi 2012.

Agenzie e sviluppo locale. Un gioco a somma zero? (articolo in rivista fascia A settore 14/D1)
No full textThe article deals with the role of regional development agencies. The author identifies two idealtypes of agency: the first one aims at attracting direct investments via financial incentives and the second focuses on the provision of local competition goods and of external economies. Looking at some empirical cases, the author underlines that both types of agencies can trigger local economic development. At the same time, looking at them more in details advantages and shortcomings of each models emerge. Finally, the possible role of this kind of organization in promoting socio-economic development of the Italian Mezzogiorno is taken into account[...
Governance territoriale dell'economia in Francia, regno Unito e Italia (articolo in rivista fascia A settore 14/D1)
No full textThe article examines recent changes in territorial governance in France, the United Kingdom and Italy. The author investigates how local competition goods are produced and allocated in three metropolitan areas (Lyon, Manchester and Turin) and in three local production systems (Roanne, Leicester and Prato), and identifies both similarities and differences among the six cases. On the one hand, these six cases share the rise of a process of political devolution, the emergence of mechanisms of local co-ordination among different economic and labour policies, the set up of ‘negotiated policies’ and the increasing adoption of contracting-out practices and of public-private partnership. On the other hand, important differences still persist: local governments, agencies, associations and large firms play different roles in the six cases. Analysing the blurring boundaries between similarities and differences it becomes possible to identify four models of economic territorial governance: local statalism for the Roanne case, agency-led governance for the Leicester and Manchester cases, local neo-corporatism for Prato and strategic planning for Lyon and Turin[...
Frontier Mountain meteorite specimens of the Acapulco-Lodranite clan: petrography, pairing and parent-rock lithology of an unusual intrusive rock
No full textIn this paper we reconstruct the heterogeneous lithology of an unusual intrusive rock from the acapulcoite-lodranite (AL) parent asteroid on the basis of the petrographic analysis of 5 small (<8.3 g) meteorite specimens from the Frontier Mountain ice field (Antarctica). Although these individual specimens may not be representative of the parent-rock lithology due to their relatively large grain size, by putting together evidence from various thin sections and literature data we conclude that Frontier Mountain (FRO) 90011, FRO 93001, FRO 99030, and FRO 03001 are paired fragments of a medium- to coarse-grained igneous rock which intrudes a lodranite and entrains xenoliths. The igneous matrix is composed of enstatite (Fs13.3±0.4 Wo3.1±0.2), Cr-rich augite (FS6.1±0.7 Wo42.3±0.9), and oligoclase (Ab80.5±3.3 Or3.2±0.6). The lodranitic xenoliths show a fine-grained (average grain size 488 ± 201 μm) granoblastic texture and consist of olivine Fa9.5±0.4 and Fe,Ni metal and minor amounts of enstatite Fs12.7±0.4 Wo1.8±0.1, troilite, chromite, schreibersite, and Ca-phosphates. Crystals of the igneous matrix and lodranitic xenoliths are devoid of shock features down to the scanning electron microscope scale. From a petrogenetic point of view, the lack of shock evidence in the lodranitic xenoliths of all the studied samples favors the magmatic rather than the impact melting origin of this rock. FRO 95029 is an acapulcoite and represents a separate fall from the AL parent asteroid, i.e., it is not a different clast entrained by the FRO 90011, FRO 93001, FRO 99030, and FRO 03001 melt, as in genomict breccias common in the meteoritic record. The specimen-to-meteorite ratio for the AL meteorites so far found at Frontier Mountain is thus 2.5
Frontier Mountain 93001: A coarse-grained, enstatite-augite-oligoclase-rich, igneous rock from the acapulcoite-lodranite parent asteroid
No full textThe Frontier Mountain (FRO) 93001 meteorite is a 4.86 g fragment of an unshocked, medium- to coarse-grained rock from the acapulcoite-lodranite (AL) parent body. It consists of anhedral orthoenstatite (Fs13.3±0.4Wo3.1±0.2), augite (FS6.1±0.7Wo42.3±0.9; Cr2O3 = 1.54 ± 0.03), and oligoclase (Ab80.5±3.3Or3.1±0.6) up to >1 cm in size enclosing polycrystalline aggregates of fine-grained olivine (average grain size: 460 ± 210 μm) showing granoblastic textures, often associated with Fe,Ni metal, troilite, chromite (cr# = 0.91 ± 0.03; fe# = 0.62 ± 0.04), schreibersite, and phosphates. Such aggregates appear to have been corroded by a melt. They are interpreted as lodranitic xenoliths. After the igneous (the term "igneous" is used here strictly to describe rocks or minerals that solidified from molten material) lithology intruding an acapulcoite host in Lewis Cliff (LEW) 86220, FRO 93001 is the second-known silicate-rich melt from the AL parent asteroid. Despite some similarities, the silicate igneous component of FRO 93001 (i.e., the pyroxene-plagioclase mineral assemblage) differs in being coarser-grained and containing abundant enstatite. Melting-crystallization modeling suggests that FRO 93001 formed through high-degree partial melting (≥35 wt%; namely, ≥15 wt% silicate melting and ∼20 wt% metal melting) of an acapulcoitic source rock, or its chondritic precursor, at temperatures ≥1200 °C, under reducing conditions. The resulting magnesium-rich silicate melt then underwent equilibrium crystallization; prior to complete crystallization at ∼1040 °C, it incorporated lodranitic xenoliths. FRO 93001 is the highest-temperature melt from the AL parent-body so far available in laboratory. The fact that FRO 93001 could form by partial melting and crystallization under equilibrium conditions, coupled with the lack of quench-textures and evidence for shock deformation in the xenoliths, suggests that FRO 93001 is a magmatic rock produced by endogenic heating rather than impact melting
