RESUMEN
Although printed networks of semiconducting nanosheets have found success in a range of applications, conductive nanosheet networks are limited by low conductivities (<106 S m-1 ). Here, dispersions of silver nanosheets (AgNS) that can be printed into highly conductive networks are described. Using a commercial thermal inkjet printer, AgNS patterns with unannealed conductivities of up to (6.0 ± 1.1) × 106 S m-1 are printed. These networks can form electromagnetic interference shields with record shielding effectiveness of >60 dB in the microwave region at thicknesses <200 nm. High resolution patterns with line widths down to 10 µm are also printed using an aerosol-jet printer which, when annealed at 200 °C, display conductivity >107 S m-1 . Unlike conventional Ag-nanoparticle inks, the 2D geometry of AgNS yields smooth, short-free interfaces between electrode and active layer when used as the top electrode in vertical nanosheet heterostructures. This shows that all-printed vertical heterostructures of AgNS/WS2 /AgNS, where the top electrode is a mesh grid, function as photodetectors demonstrating that such structures can be used in optoelectronic applications that usually require transparent conductors.
RESUMEN
This research takes a moral perspective to studying third parties' reactions to injustice as a function of their moral identity. Drawing from theories of deontic justice, moral intuition, moral heuristics, and moral identity, we develop and test a model of the moral underpinnings of third parties' reactions to injustice. First, we compare third parties' responses with interpersonal, distributive, and procedural justice violations. We hypothesize that third parties are more likely to intuit that interpersonal justice violations are morally wrong, compared with distributive and procedural justice violations. As a result, third parties are more likely to experience stronger moral anger and punish violators in response to interpersonal transgressions compared with distributive and procedural justice transgressions. Second, we test the proposition that third parties with a strong moral identity will react more strongly to justice violations than third parties with a comparatively weak moral identity. Results from 3 studies support these predictions.

Sandwell Health Visiting Service identified difficulties in recruiting and retaining health visiting staff and fully meeting the needs of vulnerable families. Following the Laming report, the decision was made to introduce health visiting supervision leads. This resulted in improvements in record keeping and care planning and in better protection and support for vulnerable families.

The purpose of this study was to assess the ethical and professional learning needs of medical trainees on clinical placements at a care-based facility, as they shifted from acute care to care-based philosophy. Using qualitative data analysis and grounded theory techniques, 12 medical learners and five clinical supervisors were interviewed. Five themes emerged as learning needs: the holistic approach to care, withdrawal of treatment and withholding investigations, the collaborative team model, violations to patient autonomy, Do Not Resuscitate and advance directives issues. The results illustrate the importance of preparing medical learners for a philosophical shift in their approach to patient care, as they move from the more cure-based approach of acute care to the care model of care-based facilities.
