Regional spillover effects of renewable energy generation in Italy

In a multivariate setting, we document that renewable energy generation has a positive impact on economic growth at the regional level in Italy. We do so by adopting panel data unit-root and cointegration tests as well as Granger non-causality tests relying on the system GMM estimator. Our results are interpreted in three ways. Renewable energy generation alleviates balance-of-payments constraints and reduces the exposure of a regional economy to the volatility of the price of fossil fuels and to negative environmental and health externalities deriving from non-renewable energy generation. Therefore, our evidence supports policies promoting renewable energy generation.renewable energy generation, economic growth, panel unit root and cointegration tests, Granger causality, Italy, panel error correction model, regions.

A Case Study of a Conflict Over a Biogas Plant

Abstract This article aims to contribute to the analysis of the complex relationship between sustainable development and green economy in mountain areas by focusing on a conflict over the building of a centralized biogas plant to produce renewable energy from livestock manure in an Italian Alpine valley. The case study shows that the project for a large-sized biogas plant promoted by the local political institutions as environmental modernization of local agriculture, and supported by the most important professional organizations, became increasingly controversial at the local community level and was eventually abandoned. By drawing in particular on the literature concerning the social acceptance of renewable energies, the article highlights how this conflict raises issues of distributional justice and procedural justice with regard to the implementation of the green economy model, and it points out the need to embed green economy technologies in the local context and conditions. These concerns should be ..

District heating and ambivalent energy transition paths in urban and rural contexts

Most institutions and industrial actors believe that district heating infrastructures can play a key role in changing urban systems towards greater sustainability and accelerate the transition to more efficient and low-carbon energy systems. We tested this belief on the Italian case, starting from a census of all existing plants, subdivided by sources of supply and business organization models. We have isolated two types of district heating, urban and rural. We found that they are different in relation to their approach to energy transition. In rural areas, networks constitute systems that can empower the local techno-institutional complex to achieve a technological leap. Set in a pre-existing social network, district heating reinforces the sense of community and allows the involvement of various local players in a collective project. In the case of biomass, we are faced with local systems that have almost completed the transition with regard to the production of thermal and sometimes electric energy. In urban areas, on the other hand, networks represent functional devices for the stabilization of the techno-institutional complex. They allow cities to work on the circularity of some economies, generating added value from the same factors of production. Eventually the clear difference between urban and rural contexts highlights the need to consider the ambivalence of district heating technology

How to Record Current Events like an Archaeologist

This article shows how to record current events from an archaeological perspective. With a case study from the COVID-19 pandemic in Norway, we provide accessible tools to document broad spatial and behavioral patterns through material culture as they emerge. Stressing the importance of ethical engagement with contemporary subjects, we adapt archaeological field methods—including geolocation, photography, and three-dimensional modeling—to analyze the changing relationships between materiality and human sociality through the crisis. Integrating data from four contributors, we suggest that this workflow may engage broader publics as anthropological data collectors to describe unexpected social phenomena. Contemporary archaeological perspectives, deployed in rapid response, provide alternative readings on the development of current events. In the presented case, we suggest that local ways of coping with the pandemic may be overshadowed by the materiality of large-scale corporate and state response

Landscape Maintenance and Farming in the Alps: From Family Firms Up-Keeping to Inter-Institutional Arrangements

This contribution discusses assets and limits of the local/territorial level as a core level to improve the sustainability of agriculture. The focus is on the issue of rural landscape maintenance through farming. Some possible institutional solutions to overcome the difficulties of family farms are examined. New institutional settings such as the "local group", constituting an interface for the negotiation among different local stakeholders, seem to effectively facilitate the stipulation of local contracts for landscape management. The participation to these contracts requires a change in farmers' identity and a more general re-conceptualization of agricultural and environmental problems as community problems.Land use, Participatory approach, Rural development, Community/Rural/Urban Development, Land Economics/Use,

A contemporary archaeology of pandemic

Global crises drastically alter human behavior, rapidly impacting patterns of movement and consumption. A rapid-response analysis of material culture brings new perspective to disasters as they unfold. We present a case study of the coronavirus pandemic in Tromsø, Norway, based on fieldwork from March 2020 to April 2021. Using a methodology rooted in social distancing and through systematic, diachronic, and spatial analysis of trash (e.g., discarded gloves, sanitization products), signage, and barriers, we show how material perspectives improve understanding of relationships between public action and government policy (in this case examined in relation to the Norwegian concept of collective labor, dugnad). We demonstrate that the materiality of individual, small-scale innovations and behaviors that typified the pandemic will have the lowest long-term visibility, as they are increasingly replaced or outnumbered by more durable representations generated by centralized state and corporate bodies that suggest close affinity between state directive and local action. We reflect on how the differential durability of material responses to COVID-19 will shape future memories of the crisis

Energy retrofitting of urban buildings: A socio-spatial analysis of three mid-sized Italian cities

3The current paper analyses the issue of energy retrofitting of buildings in Italian cities. In particular a mixed-method approach is used combining the socio-spatial analysis of data on the most relevant policy tool, namely tax deduction, together with qualitative analysis of three case studies of middle-sized cities. The results show that on the one hand tax deduction has not been very effective in promoting a deep renovation of buildings and it may exacerbate already existing inequalities. On the other hand, it emerges that progress in eco-retrofit of buildings depends mainly on creation of new intermediators and intermediation incentives. They are increasingly necessary in an urban panorama that has become inevitably polycentric.partially_openembargoed_20220430Natalia Magnani; Giovanni Carrosio; Giorgio OstiMagnani, Natalia; Carrosio, Giovanni; Osti, Giorgi

Ubiquitin-proteasome signaling in lung injury

Cell homeostasis requires precise coordination of cellular proteins function. Ubiquitination is a post-translational modification that modulates protein half-life and function and is tightly regulated by ubiquitin E3 ligases and deubiquitinating enzymes. Lung injury can progress to acute respiratory distress syndrome that is characterized by an inflammatory response and disruption of the alveolocapillary barrier resulting in alveolar edema accumulation and hypoxemia. Ubiquitination plays an important role in the pathobiology of acute lung injury as it regulates the proteins modulating the alveolocapillary barrier and the inflammatory response. Better understanding of the signaling pathways regulated by ubiquitination may lead to novel therapeutic approaches by targeting specific elements of the ubiquitination pathways.Fil: Magnani, Natalia Daniela.

Hormone deprivation alters mitochondrial function and lipid profile in the hippocampus

Mitochondrial dysfunction is a common hallmark in aging. In the female, reproductive senescence is characterized by loss of ovarian hormones, many of whose neuroprotective effects converge upon mitochondria. The functional integrity of mitochondria is dependent on membrane fatty acid and phospholipid composition, which are also affected during aging. The effect of long-term ovarian hormone deprivation upon mitochondrial function and its putative association with changes in mitochondrial membrane lipid profile in the hippocampus, an area primarily affected during aging and highly responsive to ovarian hormones, is unknown. To this aim, Wistar adult female rats were ovariectomized or sham-operated. Twelve weeks later, different parameters of mitochondrial function (O2 uptake, ATP production, membrane potential and respiratory complex activities) as well as membrane phospholipid content and composition were evaluated in hippocampal mitochondria. Chronic ovariectomy reduced mitochondrial O2 uptake and ATP production rates and induced membrane depolarization during active respiration without altering the activity of respiratory complexes. Mitochondrial membrane lipid profile showed no changes in cholesterol levels but higher levels of unsaturated fatty acids and a higher peroxidizability index in mitochondria from ovariectomized rats. Interestingly, ovariectomy also reduced cardiolipin content and altered cardiolipin fatty acid profile leading to a lower peroxidizability index. In conclusion, chronic ovarian hormone deprivation induces mitochondrial dysfunction and changes in the mitochondrial membrane lipid profile comparable to an aging phenotype. Our study provides insights into ovarian hormone loss-induced early lipidomic changes with bioenergetic deficits in the hippocampus that may contribute to the increased risk of Alzheimer’s disease and other age-associated disorders observed in postmenopause.Fil: Zarate, Sandra Cristina.
