Collective participation for the sustainable redevelopment of degraded environments and urban public space

2022

The use of participatory processes as useful tools for the regeneration of the built environment is urgently topical, also in view of the inclusive forms of decision-making that have been introduced for years by ministerial and European standards. The research is part of a well-structured cultural and regulatory context characterised by new and interesting experiments in the field. Studying the participatory process as a useful strategy for conflict management and for the construction of new regenerative models in fact also implies a clarification of "what is meant by participation and the participatory project. At the same time, as widely testified to by the production of manuals in recent…

Density-Functional Tight-Binding Simulations of Curvature-Controlled Layer Decoupling and Band-Gap Tuning in Bilayer MoS2

2014

Monolayer transition-metal dichalcogenides (TMDCs) display valley-selective circular dichroism due to the presence of time-reversal symmetry and the absence of inversion symmetry, making them promising candidates for valleytronics. In contrast, in bilayer TMDCs both symmetries are present and these desirable valley-selective properties are lost. Here, by using density-functional tight-binding electronic structure simulations and revised periodic boundary conditions, we show that bending of bilayer MoS2 sheets breaks band degeneracies and localizes states on separate layers due to bendinginduced strain gradients across the sheets. We propose a strategy for employing bending deformations in b…

“Comme ça pour le plaisir…”

2010

“Comme ca pour le plaisir…” is a quotation taken from The Little Prince of Antoine de Saint - Exupéry that in a few words summarizes the subjects I want to discuss. Is there only pleasure in creative activities? How much creativity is related with painful parts of our inner world? More in specific: has writing to do with separation issues? In the first part of my paper I will try to answer to the above questions exploring some psychoanalytical concepts, their relationship with creativity and in particular with writing. I will therefore deepen Sigmund’s Freud’s notion of sublimation, Donald W. Winnicott’s concept of transitional object and Melanie Klein’s ideas about reparation of destroyed …

Cleavage of Ge–Ge and Sn–Sn Triple Bonds in Heavy Group 14 Element Alkyne Analogues (EAriPr4)2 (E = Ge, Sn; AriPr4 = C6H3-2,6(C6H3-2,6-iPr2)2) by Rea…

2016

The reactions of heavier group 14 element alkyne analogues (EAriPr4)2 (E = Ge, Sn; AriPr4 = C6H3-2,6-(C6H3-2,6-iPr2)2) with the group 6 transition-metal carbonyls M(CO)6 (M = Cr, Mo, W) under UV irradiation resulted in the cleavage of the E–E triple bond and the formation of the complexes {AriPr4EM(CO)4}2 (1–6), which were characterized by single crystal X-ray diffraction as well as by IR and multinuclear NMR spectroscopy. Single-crystal X-ray structural analyses of 1–6 showed that the complexes have a nearly planar rhomboid M2E2 core with three-coordinate group 14 atoms. The coordination geometry at the group 6 metals is distorted octahedral formed by four carbonyl groups as well as two br…

IEA EBC Annex83 Positive Energy Districts

2021

At a global level, the need for energy efficiency and an increased share of renewable energy sources is evident, as is the crucial role of cities due to the rapid urbanization rate. As a consequence of this, the research work related to Positive Energy Districts (PED) has accelerated in recent years. A common shared definition, as well as technological approaches or methodological issues related to PEDs are still unclear in this development and a global scientific discussion is needed. The International Energy Agency’s Energy in Buildings and Communities Programme (IEA EBC) Annex 83 is the main platform for this international scientific debate and research. This paper describes the challeng…

Heritage, urbanity and transition: methods and tools for a possible future.

2021

It has taken millennia to provide our world with works of art that are sometimes comparable in magnificence and character to natural creation. Some civilizations of the past, without having any of our means, have created a historical heritage of infinite beauty. The literature on heritage and memory reports that heritage exists because society attests that an artifact, event, or place is so valuable that it is handed down to the next generation. Heritage is our anchor and beauty will save us. Architects, historians and geographers have argued that the concepts of heritage and memory are socially constructed, they shape cities and influence their identity. In the current metamorphosis, how t…

Äitien luottamuksen rakentuminen kasvattajiin varhaiskasvatuksen aloituksessa

2020

Vanhempien ja kasvattajien kasvatusyhteistyön sujuvuus heijastuu siihen, millaiseksi varhaiskasvatuksen aloitus muodostuu lapsen kokemuksena. Parhaimmillaan yhteistyön alkuvaihe tukee luottamuksen rakentumista vanhempien ja kasvattajien välille. Tässä artikkelissa kiinnostus kohdistuu luottamuksen rakentumisen prosessiin äitien näkökulmasta. Tarkastelemme miten luottamus kasvattajiin varhaiskasvatuksen instituutiossa rakentuu äitien puheessa heidän pohtiessaan lapsensa ensi kuukausia varhaiskasvatuksessa. Teoriasidonnaisen sisällönanalyysin tuella tutkimme, onko puheesta löydettävissä Rempelin, Holmesin ja Zannanin (1985) kuvaamia luottamuksen rakentumisen tasoja. Aineistona ovat viiden noi…

Relational approach to infant-teacher lap interactions during the transition from home to early childhood education and care

2022

The transition from home care to early childhood education and care (ECEC) is a period of intense change and development in young children's socio-spatial worlds. This article focuses on infant–teacher lap interactions during this transition period. This investigation applies a relational approach to the study of infant–teacher lap interactions. In doing so, it highlights the inherently social and contextual nature of interaction. From a relational perspective, actors, context, and situation are seen as constitutive of each other, and their interrelationality is considered central to the emergence of interactions. The data, regarding infants' first months attending ECEC in Finland, is compo…

Stabilise, balance and adjust : Framing the early years transitions of children whose parents work non‐standard hours

2022

This study examined talk by parents about the early years transitions of their children (n = 7) in the context of parental non-standard working hours and Finnish early childhood education and care (ECEC) services. Parents were interviewed at three time points: when their child was aged one, four, five or six years (a total of 21 interviews). The third interview was conducted during the COVID-19 pandemic. This article focuses on the children's ECEC transitions and the interpretative frames used by parents when talking about their work and childcare. The frames used by the parents to discuss the children's transitions were stabilising the children's lives, balancing between staying at home an…
