Families_Share: digital and social innovation for work–life balance

Purpose: The European H2020 Families_Share project aims at offering a grass-root approach and a co-designed platform supporting families for sharing time and tasks related to childcare, parenting, after-school and leisure activities and other household tasks. To achieve this objective, the Families_Share project has been built on current practices which are already leveraging on mutual help and support among families, such as Time Banks, Social Streets and self-organizing networks of parents active at the neighbourhood level and seek to harness the potential of ICT networks and mobile technologies to increase the effectiveness of participatory innovation. The aim of this paper is to present and discuss the Families_Share methodology and platform, as well as the results obtained by several partecipating communities in different European countries. Design/methodology/approach: This paper discusses how the Families Share approach (CAPS project, Horizon 2020) is bringing the sharing economy to childcare. Families Share developed a co-caring approach and a co-designed digital welfare platform to support parents with sharing time and tasks related to childcare, after-school and leisure activities. Families Share conducted two iterative pilot experiments and related socio-economic evaluations in six European cities. More than 3,000 citizens were engaged in the co-design process through their local community organizations and more than 1,700 parents and children actively experimented with the approach by organizing collaborative childcare activities. The authors discuss the challenges and solutions of co-designing a socio-technical approach aimed at facilitating socially innovative childcare models, and how the Families Share approach, based on technology-supported co-production of childcare, may provide a new sustainable welfare model for municipalities and companies with respect to life––work balance. Findings: The authors discuss the challenges and solutions of co-designing a technological tool aimed at facilitating socially innovative childcare models, and how the Families Share approach may provide a new sustainable welfare model for municipalities and companies with respect to work–life balance. Originality/value: As a main difference with state-of-the-art proposals, Families_Share is aimed to provide support to networks of parents in the organization of self-managed activities, this way being orthogonal with respect either to social-network functionalities or to supply and demand services. Furthermore, Families_Share has been based on a participative approach for both the ICT platform and the overall structure

Regioisomeric and substituent effects upon the outcome of the reaction of 1-borodienes with nitrosoarene compounds

A study of the reactivity of 1-borodienes with nitrosoarene compounds has been carried out showing an outcome that differs according to the hybridization state of the boron moiety. Using an sp2 boron substituent, a one-pot hetero-Diels–Alder/ring contraction cascade occurred to afford N-arylpyrroles with low to good yields depending on the electronic properties of the substituents on the borodiene, whereas an sp3 boron substituent led to the formation of stable boro-oxazines with high regioselectivity in most of the cases, in moderate to good yields. 1H and 11B NMR studies on two boro-oxazine regioisomers showed that selective deprotection can be performed. Formation of either the pyrrole or the furan derivative is pH- and regioisomer-structure-dependent. The results obtained, together with previous B3LYP calculations, support mechanistic proposals which suggest that pyrrole, or furan, formation proceeds via oxazine formation, followed by a boryl rearrangement and an intramolecular addition–elimination sequence

Enantiospecific sp(2)-sp(3) coupling of secondary and tertiary boronic esters

The cross-coupling of boronic acids and related derivatives with sp² electrophiles (the Suzuki–Miyaura reaction) is one of the most powerful C–C bond formation reactions in synthesis, with applications that span pharmaceuticals, agrochemicals and high-tech materials. Despite the breadth of its utility, the scope of this Nobel prize-winning reaction is rather limited when applied to aliphatic boronic esters. Primary organoboron reagents work well, but secondary and tertiary boronic esters do not (apart from a few specific and isolated examples). Through an alternative strategy, which does not involve using transition metals, we have discovered that enantioenriched secondary and tertiary boronic esters can be coupled to electron-rich aromatics with essentially complete enantiospecificity. As the enantioenriched boronic esters are easily accessible, this reaction should find considerable application, particularly in the pharmaceutical industry where there is growing awareness of the importance of, and greater clinical success in, creating biomolecules with three-dimensional architectures

Copper-based corrole as thermally stable hole transporting material for perovskite photovoltaics

Perovskite solar cells (PSCs) represent nowadays a promising starting point to develop a new efficient and low-cost photovoltaic technology due to the demonstrated power conversion efficiency (PCE) exceeding 25% on small area devices. However, best reported devices suffer from stability issue under real working conditions thus slowing down the race for the commercialization. In particular, the hole transporting material commonly employed in mesoscopic n–i–p PSCs (nip-mPSCs), namely spiro-OMeTAD, is strongly corrupted when subjected to temperatures above 70 °C due to intrinsic thermal instability and because of the dopant employed to improve the hole mobility. In this work, the novel use of a copper-based corrole as HTM is proposed to improve the device thermal stability of nip-mPSCs under prolonged 85 °C stress conditions. Corrole-based devices show remarkable PCE above 16% by retaining more than 65% of the initial PCE after 1000 h of thermal stress, while spiro-OMeTAD cells abruptly lose more than 60% after the first 40 h. Once scaled-up to large area modules, the proposed device structure can truly represent a possible way to pass thermal stress tests proposed by IEC-61646 standards and, not less importantly, the high temperature required by the lamination process for panel production

Structure of nonlocality of plasma turbulence

International audienceVarious indications on the weakly nonlocal character of turbulent plasma transport both from experimental fluctuation measurements from Tore Supra and observations from the full-f, flux-driven gyrokinetic code GYSELA are reported. A simple Fisher equation model of this weakly nonlocal dynamics can be formulated in terms of an evolution equation for the turbulent entropy density, which contains the basic phenomenon of radial turbulence spreading in addition to avalanche-like dynamics via coupling to profile modulations. A derivation of this model, which contains the so-called beach effect, a diffusive and convective flux components for the flux of turbulence intensity, in addition to linear group propagation is given, starting from the drift-kinetic equation. The proposed model has the form of a transport equation for turbulence intensity, and may be considered as an addition to transport modelling. The kinetic fluxes given, can be computed using model closures, or local gyrokinetics. The model is also used in a particular setup that represents the near edge region as a relatively stable zone between the core and edge region where the energy injection is locally more substantial. It is observed that with constant, physical coefficients, the model gives a convincing qualitative profile of fluctuation intensity when the turbulence is coming from the core region with either a group velocity or a convective flux
