The Matter of Future Heritage
In 2018, for the first time, the University of Bologna’s Board of PhD in Architecture and Design Culture assigned second-year PhD students the task of developing and managing an international conference and publishing its works. The organisers of the first edition of this initiative – Giacomo Corda, Pamela Lama, Viviana Lorenzo, Sara Maldina, Lia Marchi, Martina Massari and Giulia Custodi – have chosen to leverage the solid relationship between the Department of Architecture and the Municipality of Bologna to publish a call having to do with the European Year of Cultural Heritage 2018, in which the Municipality was involved.
The theme chosen for the call, The Matter of Future Heritage, set itself the ambitious goal of questioning the future of a field of research – Cultural Heritage (CH) – that is constantly being redefined. A work that was made particularly complex in Europe by the development of the H2020 programme, where the topic entered, surprisingly, not as a protagonist but rather as an articulation of other subjects that in the vision of the programme seemed evidently more urgent and, one might say, dominant. The resulting tensions have been considerable and with both negative and positive implications, all the more evident if we refer to the issues that are closest to us namely the city and the landscape
The galaxy stellar mass function at 3.5 ≤z ≤ 7.5 in the CANDELS/UDS, GOODS-South, and HUDF fields
Context. The form and evolution of the galaxy stellar mass function (GSMF) at high redshifts provide crucial information on star formation history and mass assembly in the young Universe, close or even prior to the epoch of reionization. Aims: We used the unique combination of deep optical/near-infrared/mid-infrared imaging provided by HST, Spitzer, and the VLT in the CANDELS-UDS, GOODS-South, and HUDF fields to determine the GSMF over the redshift range 3.5 ≤ z ≤ 7.5. Methods: We used the HST WFC3/IR near-infrared imaging from CANDELS and HUDF09, reaching H ≃ 27 - 28.5 over a total area of 369 arcmin2, in combination with associated deep HST ACS optical data, deep Spitzer IRAC imaging from the SEDS programme, and deep Y and K-band VLT Hawk-I images from the HUGS programme, to select a galaxy sample with high-quality photometric redshifts. These have been calibrated with more than 150 spectroscopic redshifts in the range 3.5 ≤ z ≤ 7.5, resulting in an overall precision of σz/ (1 + z) ~ 0.037. With this database we have determined the low-mass end of the high-redshift GSMF with unprecedented precision, reaching down to masses as low as M∗ ~ 109 M☉ at z = 4 and ~6 × 109 M☉ at z = 7. Results: We find that the GSMF at 3.5 ≤ z ≤ 7.5 depends only slightly on the recipes adopted to measure the stellar masses, namely the photometric redshifts, the star formation histories, the nebular contribution, or the presence of AGN in the parent sample. The low-mass end of the GSMF is steeper than has been found at lower redshifts, but appears to be unchanged over the redshift range probed here. Meanwhile the high-mass end of the GSMF appears to evolve primarily in density, although there is also some evidence of evolution in characteristic mass. Our results are very different from previous mass function estimates based on converting UV galaxy luminosity functions into mass functions via tight mass-to-light relations. Integrating our evolving GSMF over mass, we find that the growth of stellar mass density is barely consistent with the time-integral of the star formation rate density over cosmic time at z> 4. Conclusions: These results confirm the unique synergy of the CANDELS+HUDF, HUGS, and SEDS surveys for the discovery and study of moderate/low-mass galaxies at high redshifts, and reaffirm the importance of space-based infrared selection for the unbiased measurement of the evolving GSMF in the young Universe.

Cultivar ciudades. Delineaci\uf3n de una utop\ueda de mejores entornos urbanos, autosuficientes y resilientes
Urban agglomerations and their effects on ecosystem are the dominant feature of our current and future political agenda, as well as we definitely understood that human activities and natural processes are linked together in a complex new whole: the Antropocene. Many of the most promising ideas in this field are those related to the reactivation and reclamation of variable patterns related to open space as generator of new urban-rural linkages. The paper traces an overview on the periurban contexts, for a long time seen only in terms of land-cover consumption. Today they are complex realities that interpret the changes taking place in the territories, defining measures of co-planning, providing alternative services and promoting networks of relationships between farming communities and citizens
ReCycle: A territory-based approach
The different contributions of the LUH group to the Re-Cycle research conceive the intrinsically connected transformations of the city and of the countryside as holistic sustainable approach. In a larger frame of territory and society, many researches address bottom-up phenomena as \u201cUrban Catalysts\u201d or \u201cMicroplanning\u201d with the intention to systemize practices of citizens and so-called \u201curban creatives\u201d in appropriating and transforming spatial fragments with intents of urban transformation in general. Working on the relations between the smaller and the larger, between the object and the context, the figure with the ground, dealing with puzzles, fragments, concentrations, dispersions, patterns: the double role of urbanism

Il progetto APICE: verso la mitigazione dell’inquinamento atmosferico prodotto dalle attività portuali a Genova e in altre città del Mediterraneo
Harbours represent a significant potential for the economic development all over the Med basin, but they also have a potential negative environmental impact due to multiple emission sources. The presence of competing activities in coastal areas can lead to potential conflicts which need to be managed by the institutional actors. APICE - Common Mediterranean strategy and local practical Actions for the mitigation of Port, Industries and Cities Emissions – proposes a decision-making approach that assumes the impact of air pollution sources as driver for the coast management in port-cities which includes Venice, Genoa, Barcelona, Marseille and Thessaloniki. For each Pilot areas both scientific and policies issues are taken into account, through the participation of one scientific and one institutional partner dealing with planning topics. This vision enforces one of the basic concepts of Integrated Management of Coastal Zones (ICZM) as well as Lisbon and Gothenburg Strategies, aiming at strengthen the dynamism of European competitiveness whilst ensuring social cohesion and sustainable development, and with the MED Operational Programme 2007-2013

Re-cycle Italy: Atlante: 5. Re-cycle Footprint
Un atlante è un atlante. È una raccolta di mappe che rappresentano uno spazio misurabile. Di solito gli atlanti mettono insieme la cartografia cominciando dalla scala più vasta fino ad arrivare agli approfon- dimenti tematici o alla scala locale. Cristoforo Buon- delmonti, un monaco geografo italiano della fine del 1300, per primo integrò negli Isolari oltre allo spazio misurabile il senso degli spazi descritti. Se gli Atlan- ti descrivono gli spazi, gli Isolari raccontano i luoghi, come scrive Franco Farinelli1. Questo Atlante delle Impronte da Riciclo cerca di fare tutte e due le cose. È una raccolta di mappe che misurano le riserve di spazio del patrimonio architettonico paesaggistico e urbano abbandonato, inutilizzato e dismesso a par- tire dalla scala di riferimento più grande che in que- sto caso è quella nazionale per la natura stessa del- la ricerca Recycle Italy. Ma anche, come un Isolario, l’Atlante delle Impronte da Riciclo serve a racconta- re le storie, cioè le occasioni e il senso delle azioni progettuali che possono innescare nuovi cicli di vita dei materiali paesaggistici, architettonici e urbani in sede locale
