Connection between Design and Nature Reflections and Projects for the future of the Planet
2022
Humanity’s delayed reaction to the consequences of the climate crisis is the result of multiple interests and strategies caused by denialist policies and piloted information. It is also true, however, that there is a strictly cultural responsibility, in the form of a lack of dialogue between sources of knowledge. Restoring the balance between humanity and nature is the most important issue that contemporary design must address. Design has the task of highlighting objects and strategies in re-establishing the relationship between Man and the context in which he lives by re-integrating the social and natural ecosystems. In this context, thanks to the evolution of natural sciences and technolo…
Achievements, flaws, and future goals of scientific research on green roofs in mediterranean cities: first feedback from ongoing meta-analysis
2022
Current scientific research points out the low number of papers focused on the environmental patterns in Mediterranean urban areas, where green infrastructure is still strongly underrated by scientists as well as by politicians, planners and decision-makers. In this paper, the results of a simple meta-analysis on the topics treated in scientific literature about the Mediterranean green roofs (MGRs) are presented. Our review pointed out the strikingly higher attention paid to building materials, energy efficiency and hydraulics with respect to life sciences (including basic ecology, horticulture, soil, plant and animal sciences) in the target paper selection. In fact, despite the availabilit…
Place-Keeping and Ecological Services. Una prospettiva di Studi
2016
La diffusione di azioni di appropriazione e gestione condivisa di aree verdi urbane residuali o degradate (place-keeping) rende manifesto un cambio di prospettiva da parte dei cittadini. Esse legano il dibattito sugli urban commons e sulle pratiche di condivisione alla più generale questione ecologica urbana, e inducono a un ripensamento degli standard in senso prestazionale. Il contributo presenta i primi risultati di una ricerca più ampia, tuttora in corso, che indaga i servizi ecosistemici erogati nei casi di place-keeping, evidenziando analogie e differenze rispetto alle aree verdi tradizionalmente pianificate, e analizza il ruolo e la partecipazione dei cittadini nel progetto e nella g…
Does diversification pay in the app market? Evidence from Apple's App Store and Google Play
2016
In this paper we address the study of the effects of product line diversification on firm performance in the mobile application market. Specifically, we shed light on whether the distribution platform ecosystem where developers commercialize their apps influence the effect of product line diversification, i.e., diversification across different app categories, on developer sales performance. To these purposes, we compare the sales performance of diversified developers with that of category-specialized developers in the two major app stores (namely, Apple’s App Store and Google Play). Our results show that the diversification strategy has a positive impact on developer sales in Google Play, w…
Monitoring tropical forests under a functional perspective with satellite-based vegetation optical depth.
2020
Monitoring ecosystem functions in forests is a priority in a climate change scenario, as climate-induced events may initially alter the functions more than slow-changing attributes, such as biomass. The ecosystem functional properties (EFPs) are quantities that characterize key ecosystem processes. They can be derived by point observations of gas and energy exchanges between the ecosystems and the atmosphere that are collected globally at FLUXNET flux tower sites and upscaled at ecosystem level. The properties here considered describe the ability of ecosystems to optimize the use of resources for carbon uptake. They represent functional forest information, are dependent on environmental dri…
ANTHROPOCENE: NEW ENCOUNTERS, OLD PATTERNS. A FEW COMMENTS ON PAYMENTS FOR ECOSYSTEM SERVICES
2021
This paper focuses on one of the answers that have been given to the question: what type of change is to be pursued to limit human impact on the Earth while considering the needs of poor and disadvantaged communities? In particular it looks at a proposal that combines sustainable development approaches with market mechanisms and top- down technocratic responses: Payments for Ecosystem Services frameworks. They have been criticized by many points of view and this paper questions, in particular, their very reliance on the market, questioning their appropriateness for the regulation of conser- vation activities and their interaction with local communities.
La Sicilia negli Orsi di Dino Buzzati e Lorenzo Mattotti
2022
Nella fiaba illustrata di Dino Buzzati La famosa invasione degli orsi in Sicilia (1945) e nella sua trasposizione filmica ad opera di Lorenzo Mattotti (2019) l’ambientazione siciliana è determinante. In entrambi i casi la Sicilia è un’isola con un grande vulcano – trasfigurata in un ambiente fantastico o riscritta secondo alcuni stereotipi – che i due autori utilizzano con accezioni diverse nella costituzione dell’ecosistema delle loro narrazioni. Soltanto attraverso una comparazione tra le due opere sarà possibile distinguere la rappresentazione delle due Sicilie che vengono raccontate con un intervallo di circa settanta anni. Se non si considera la storia degli Orsi soltanto una fiaba per…
Understanding the Microfoundations of Entrepreneurial Ecosystems: Toward a Value-Based Method and Theory
2023
Despite the progress made by scholars, empirically investigating entrepreneurial ecosystems (EEs) remains problematic because of the inherent complexities and nonlinearities of interactions among EE actors. The research to date has shown a tendency to focus on macrolevel ecosystem dynamics while neglecting the microfoundations of EEs. We contend that this negligence is due to a lack of appropriate methodologies that can capture EE microfoundations through a systemic value-based perspective. To fill this gap, in this article, we propose a novel methodological approach, the value system method, which enables framing EEs through critical causal interdependences between key actors’ business mod…
Tracing the anthropocene back and forward: Rights for ecosystem services, local communities, and REDD
2020
The author of the book When Rights Embrace Responsibilities. Biocultural Rights and Conservation of the Environment replies to the comments raised by Francesco Viola and Gianfrancesco Zanetti in the present journal issue. She also dwells on some topics of her book which deserve further clarification and speculates on possible future developments of biocultural rights.
Disentangling conditional effects of multiple regime shifts on Atlantic cod productivity
2020
AbstractRegime shifts are increasingly prevalent in the ecological literature. However, definitions vary, and many detection methods are subjective. Here, we employ an operationally objective means of identifying regime shifts, using a Bayesian online change-point detection algorithm able to simultaneously identify shifts in the mean and(or) variance of time series data. We detected multiple regime shifts in long-term (59-154 years) patterns of coastal Norwegian Atlantic cod (>70% decline) and putative drivers of cod productivity: North Atlantic Oscillation (NAO); sea-surface temperature; zooplankton abundance; fishing mortality (F). The consequences of an environmental or climate-relate…
