No full textIn the present-day city, the quality of the places is not just the result of its architecture but is increasingly linked to a diffused urban landscape; a sort of Buzz design, the definition Andrea Branzi uses for the shower of small and medium-size projects that contribute to creating a new level of expression and culture of the urban setting. The new nature of urban areas leads to some reflections about the competencies that are necessary for their organic planning, not strictly imposed from above, but acting more through an integrated system of micro-interventions that are better apt to deal with the characteristics of volatility, temporariness, and velocity of adjustment, typical of the postmodern era. Planning expertise, capable of connecting different disciplines in a context marked by complexity, generating a global transformation through local and specific interventions, from interiors to urban landscape, applying the concept of “see small to see more.”
The essay aims to investigate the design approach to urban transformations through the interpretation of several theories including Ugo La Pietra's interior through exterior, the urban leftovers theorized by Luciano Crespi, and the in-between spaces identified in Giovanna Piccinno's publications. Through a critical reading, the text identifies how the design of interiors and spaces becomes, therefore, a tool for urban space’s re-development through different approaches linked by a single crucial theme: the centrality of space’s user, according to the Global Public Space Toolkit (2016), which defines a public place, “a portion of an area or location designated or available for or being used by someone. Place comes to existence when people give meaning to a part of a larger space. Places that have a strong sense of place have an identity and character felt by local inhabitants “.
The importance of urban space, meant as a connective space, a space of sociality, a space of connection between public and private, emerges even more strongly in these years in which the health emergency has led, on the one hand, to an increase in the use of the outdoor space as an appendix and an alternative to confined space, and, on the other hand, to regain the meaning of place dedicated to the community, a platform of personal and physical relationships and a medium for the recognition and sense of belonging of the inhabitant.
“In contemporary societies, public space has become a medium, a tool, an enabler, a place where everybody should feel included and have the possibility of personalizing, reclaiming and conquering it. At the same time, public space is the best platform for designers to think about the future of cities. It is the ideal framework for testing and prototyping new ideas and possibilities, and creating future scenarios that can then be shared, discussed, and debated. Public space should be the place where individual and societal freedom is most represented and by rethinking and re-shaping it, designers are affecting people’s present and future lives. In this framework, design is a powerful and meaningful instrument to transform public space from a mirror in which society is merely reflected into a tool that can change society in a collaborative way. However, design should not be approached only as a physical and material intervention. The way in which urban transformation processes are conceptualized and ignited can also be designed and curated to foster an augmented citizenship more active and conscious.” (Tato et alii 2020)

No full textA manipulation experiment on ozone enrichment and increased nitrogen deposition has been performed in 2012 in Northern Italy on young trees of Quercus robur and Carpinus betulus, two of the most representative species of forest vegetation of the Po valley and the pre-alpine region. Two hundreds and twentyfour saplings of each species have been potted and placed in 12 Open-Top Chambers following a split-plot design with 3 randomized blocks and two factors: ozone concentration, the main factor, at 4 different levels (CF, AA, AA+35%, AA+70%), and nitrogen irrigation, the nested factor, at 2 different levels (tap water, tap water + 70Kg of N*ha*y-1).
Saplings growth and physiological have been monitored during the whole growing season from April to the end of September. Gas exchange measurements were performed once a month as well as photosynthetic performance of PSII and stomatal conductance measurements (3 daily cycles).
Moreover A/Ci and A/Light response curves have been made in June and September to assess the maximum carboxylation rate of RuBisCO, the maximum assimilation at non-limiting Ci concentration, photorespiration and dark respiration rates. At the end of the growing season half of the saplings have been harvested in order to estimate the total biomass production and its root/shoot partition.
Preliminary results of the first year of experimentation (ECLAIRE experiment will last two years) reveal significant positive effects of nitrogen and negative effects of ozone at photosynthetic level in both species.
Effects on growth and biomass partition were detected only for nitrogen, particularly for Q. robur, while the ozone effects were weak and scattered. The only detectable effect of ozone was a clear reduction of stomatal conductance starting from the mid-season. This fact highlights the need to include a f(O3) modifying function in the stomatal conductance models, one of which is proposed for these two species.
The interaction between the two factors shows an antagonistic effects of nitrogen and ozone on the photosynthetic parameters.
The observed incoherence among the ozone effects on photosynthetic parameters and the real plant growth rises a question about the possibility to predict ozone impacts on plant growth with a purely modellistic approach based upon photosynthesis and, once again, highlights the need to set up and support pluriannual experiments on field

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
