Tra polis e oikia. Considerazioni sul "sesso debole" a partire dalla quarantena
No full textIl contributo si interroga sulle ragioni di quella che appare una scarsa incisività nelle risposte e contro-narrazioni femminili riferibili all'evento pandemico e all'emergenza sanitaria. In tale prospettiva, l'indagine si rivolge a ritroso sui modi in cui voci storiche del femminismo italiano hanno messo a tema il binomio dentro/ fuori (oikia/polis) come fondamento politico dell’esclusione femminile dallo spazio pubblico e della gerarchizzazione dei generi.
In conclusione, viene avanzata l'ipotesi che la radicalità del rifiuto a lungo apposto all’uguaglianza e alla parità da parte del pensiero della differenza italiano abbia sedimentato una memoria culturale che non agevola nel porre la questione della partecipazione sociale femminile né in condizioni ordinarie né, tanto meno, in situazioni emergenziali
L'amore tra differenza e rischio: una lettura del Frammento postumo
No full textIl contributo rilegge e interpreta un celebre testo incompiuto
dell’ultimo Simmel, il Fragment über die Liebe, ponendo in evidenza similitudini o assenze emergenti dal raffronto con altri lavori simmeliani vicini vuoi per argomento vuoi perché scritti nell'ultima fase della vita.
La parte finale si concentra sulla possibile attualizzazione della riflessione simmeliana, evidenziando come questo autore classico della sociologia possa fornire elementi utili a comprendere tendenze e processi contraddittori oggi in atto
Heat island effects in urban life cycle assessment: Novel insights to include the effects of the urban heat island and UHI‐mitigation measures in LCA for effective policy making
No full textUrbanization often entails a surge in urban temperature compared to the rural surroundings: the Urban Heat Island (UHI) effect. Such a temperature increase triggers the formation of pollutants worsening the urban air quality. Jointly, bad air quality and UHI affect ecosystems and human health. To alleviate the impacts on the population and the environment, it is crucial to design effective UHI‐mitigation measures. Life Cycle Assessment (LCA) is an assessment tool able to capture the complexity of urban settlements and quantify their impact. Yet, as currently implemented, LCA neglects the interactions between the built environment and the local climate, omitting the resulting impacts. This study reviews the existing literature, showing the lack of studies that organically include interactions between the built environment and local climate in LCA. This forms the basis to identify the unsuitability of the current LCA framework for comprehensively capturing the impact of urban settlements. To overcome this limitation, this research offers a pathway to expand the LCA methodology, indicating the necessity to (a) couple the LCA methodology with climate models or physical relations that quantify the interactions between the local climate and the built environment; (b) include novel impact categories in LCA to address such interactions; and (c) use existing or ad hoc developed characterization factors to assess the impacts related to the UHI effect. The LCA community can build on the frame of reference offered by this research to overcome the current limitations of LCA and enable its use for a comprehensive assessment of the impacts of UHI and its mitigation measures
Not just political parties: Robert Michels as a critic of mainstream economics
No full textBest known for his contribution to elite theory through the formulation of the principle of oligarchy, Robert Michels pursued a critique of economic reductionism for decades. In this paper, I examine some significant passages from Michels’ writings to clarify the significance of his criticism of the dominant economics of his time. This provides an overview of an author partly conditioned by his adherence to Italian fascism but still able to distance himself progressively from productivist ideology while anticipating current lines of research focusing on the relationship between the market and society, such as civil economy. Moreover, by investigating how goods may provide happiness, Michels expressed a sophisticated and contemporary view of consumption, already bringing into focus the logic of distinction that Pierre Bourdieu examined in the second half of the twentieth century. By also attempting to do all this in an interdisciplinary way, Michels represents a scholar whom the social sciences and sociology should rediscover in the face of the challenges of the twenty-first century

Building integrated vegetation effect on micro-climate conditions for urban heat island adaptation. Lesson learned from Turin and Rome case studies
No full textThe proposed study investigates the effect of urban heat island mitigation scenarios by applying extensive green roofs, green façades, and living walls to two built areas within Turin and Rome, Italy. Three mitigation scenarios and a baseline one have been developed in ENVI-met software for each built area and run for a typical winter day, summer day, and summer day with a heat wave. The simulation results show that building integrated vegetation technology-application on a single building has an irrelevant effect on local temperatures; contrariwise, building integrated vegetation technology-wide application can effectively mitigate urban warming. Furthermore, the effect of green roofs and green walls on urban temperature is negligible in winter, likely because of the limited plant activity and the reduced amount of incoming solar radiation. Results also show that green façades are more effective than green roofs in mitigating pedestrian-level air temperature when installed on high-rise buildings, and green walls are more beneficial in mitigating summer urban heat island when installed in canyons parallel to wind direction than in perpendicular ones. Depending on the mitigation scenario, average decreases in urban temperatures up to 1 °C can be reached in the whole selected built area, alleviating urban warming
Development of predictive indices for evaluating the UHI adaptation potential of green roof- and wall-based scenarios in the Mediterranean climate
No full textUrban heat islands can jeopardize urban inhabitants, but the installation of green roofs (GRs) and walls (GWs) can contribute to mitigating urban overheating. The present study provides novel indices to easily predict the spatial median variation in air temperature at pedestrian heights related to the application of GR- and GW-based scenarios during the hottest hours of a typical summer day by varying the building height (BH), coverage percentage, and leaf area index. The indices are meant to be applied to built areas with 0.3–0.4 urban density in the Mediterranean climate and are derived from regression models fed with the outputs of 281 simulations of three urban areas developed and run in ENVI-met software. The developed models are all highly significant. The GR model shows that mitigation is influenced by all three parameters, and it can estimate mitigation with a root mean square error of 0.05 °C. Compared with the other parameters, the GW models revealed that the BH did not influence the decrease in air temperature. The green façade and living wall (LW) indices predict mitigation with errors of 0.04 °C and 0.05 °C, respectively. However, for the LW model, further parameters should be considered to improve its reliability
