Recommendations for reporting equivalent black carbon (eBC) mass concentrations based on long-term pan-European in-situ observations
Marjan Savadkoohi, Marco Pandolfi, Olivier Favez, Jean-Philippe Putaud, Konstantinos Eleftheriadis, Markus Fiebig, Philip Hopke, Paolo Laj, A. Wiedensohler, Griša Močnik, 2024, original scientific article

Abstract: A reliable determination of equivalent black carbon (eBC) mass concentrations derived from filter absorption photometers (FAPs) measurements depends on the appropriate quantification of the mass absorption cross-section (MAC) for converting the absorption coefficient (babs) to eBC. This study investigates the spatial–temporal variability of the MAC obtained from simultaneous elemental carbon (EC) and babs measurements performed at 22 sites. We compared different methodologies for retrieving eBC integrating different options for calculating MAC including: locally derived, median value calculated from 22 sites, and site-specific rolling regression MAC. The eBC concentrations that underwent correction using these methods were identified as LeBC (local MAC), MeBC (median MAC), and ReBC (Rolling MAC) respectively. Pronounced differences (up to more than 50 %) were observed between eBC as directly provided by FAPs (NeBC; Nominal instrumental MAC) and ReBC due to the differences observed between the experimental and nominal MAC values. The median MAC was 7.8 ± 3.4 m2/g from 12 aethalometers at 880 nm, and 10.6 ± 4.7 m2/g from 10 MAAPs at 637 nm. The experimental MAC showed significant site and seasonal dependencies, with heterogeneous patterns between summer and winter in different regions. In addition, long-term trend analysis revealed statistically significant (s.s.) decreasing trends in EC. Interestingly, we showed that the corresponding corrected eBC trends are not independent of the way eBC is calculated due to the variability of MAC. NeBC and EC decreasing trends were consistent at sites with no significant trend in experimental MAC. Conversely, where MAC showed s.s. trend, the NeBC and EC trends were not consistent while ReBC concentration followed the same pattern as EC. These results underscore the importance of accounting for MAC variations when deriving eBC measurements from FAPs and emphasizes the necessity of incorporating EC observations to constrain the uncertainty associated with eBC.

STAGED CONCERT of the DIPLOMACY COLLECTIVE
Peter Purg, Fabian Koppri, Francisco Catalán, Morris Kliphius, Stange Madlen, Véronique Ehrsam, 2019, artistic work

Abstract: This site-specific one-time performance joined 7 musicians/performers, as well as the participating audience, in a joint experience of sound, space and music. It was devised as a premiere performance at the ART FESTIVAL, 29.-31-3-2019 in Berlin, Germany at the "Atelierhaus Australische Botschaft".

The Resiege of Neptun
Peter Purg, 2017, artistic work

Abstract: After the Neptun Trilogy (2011-13) and its Re:enactment in 2014 (vimeo.com/119334124), the performer returns to the site -- now taken over by yet another corporation: The ex-Neptun factory in Komiža, island of Vis (Croatia) was being used as one of the strictly closed areas on the island for shooting of the Hollywood blockbuster Mamma Mia 2. Since the production of part one left a small idyllic Greek island had bereft of peace and well-being, the islanders accepted it with much ambivalence. Thus Neptun's pier had to be sieged again, even if only at its floating tip, the plastic pontoon (02:25 - 02:45 ).

Čuvari (Keepers)
Peter Purg, 2017, artistic performance

Abstract: The pavement reconstructions in the Belgrade University of the Arts area at Kosančičev venac had been going on for months, and heaps of cobblestone. Sand just kept being moved from one side of the rubble-filled street to the other. Suddenly one afternoon, on the 30th of March 2017, a little bed of dry (stonewall) plants appeared on the top of the biggest sand heap. They remained there for a whole month, somebody must have been caring for them... Soon after they suddenly disappeared, another big bright flower took their place immediately -- but on the very same day (April 28th), that flower disappeared, too. The documentary photos were taken (in the order of gallery appearance) every couple of days throughout April 2017 -- special thanks to (photo by) Rastko Čirić and Danica Bojić

New Collaboration Forms in Site-specific Blended Courses Abroad: : Lessons Learned in the ADRIART.net Curriculum Development Project
Peter Purg, Daniela Brasil, 2016, original scientific article

Abstract: A condensed programme of international courses with site-specific focus was developed as part of the collaborative art study programme Media Arts and Practices. Among higher-education partners from Italy, Austria, Croatia, and Slovenia the collaboration crossed the realms of new-media and contemporary art, film, animation, photography and scenography. Aiming at art pedagogy practitioners including art-school managers, who plan to develop or implement similar forms of intensive courses or programmes, the article discusses several key phenomena emerging among different stakeholders of the artistic or media-production education process. A plethora of research-and-development data, gathered along the three years of the collaborative study programme provision and intensive short-term course deployments, were condensed into lessons-learned that focus around the aspects of (blended) course design, interdisciplinary teaching and production methods, academic feedback and critique, as well as impact on local stakeholders. By shedding multi-layered light at site-specific art pedagogy along four short case-comparisons (from Graz, Komiža, Rijeka, and Venice), the article reflects an important trend in the arts—increasingly hybrid, multidisciplinary practices. It shows how social and (aesth)ethical change is well possible within a culturally reflected art pedagogy-cum-production setting that can materialize a collective and meaningful impact on a specific site, and its social tissue.
