What characterises well‐connected schools? Exploring centrality in inter‐organisational school networks

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Within the educational literature, inter‐organisational school networks are commonly considered instruments for administration, management, and school improvement, but are rarely scrutinised as objects of study themselves. Conversely, in organisational studies, this perspective is given more prominence.

Ch‐Ch‐Ch‐Ch‐Changes: The Impact of Supply Base Growth, Contraction, and Turnover on Firm Innovation

open access: yesJournal of Operations Management, EarlyView.
ABSTRACT Modern supply chains are experiencing more disturbances due to regulatory shifts, rising sustainability standards, emerging or declining markets, and disruption to critical inputs. Some firms react by strengthening existing supplier partnerships to resist changes, while others reconfigure relationships with suppliers to embrace changes ...

Semi-Supervised Learning for Neural Keyphrase Generation

open access: yes, 2018
We study the problem of generating keyphrases that summarize the key points for a given document. While sequence-to-sequence (seq2seq) models have achieved remarkable performance on this task (Meng et al., 2017), model training often relies on large ...

Superplasticity of Fine-Grained Magnesium Alloy AZ31 Processed by Multi-Directional Forging

open access: yesMATERIALS TRANSACTIONS, 2007
Superplasticity was studied in a fine-grained magnesium alloy AZ31 processed by multidirectional forging (MDF) under decreasing temperature conditions. Tensile tests were carried out at temperatures from 393 K to 473 K and at various strain rates. Superplasticity appears even at a low temperature of 393 K with a stress exponent of around 5.6 and a ...

Stress‐guided photo‐programming of cholesteric liquid crystal elastomers for 2D‐to‐3D shape–color information encoding

open access: yesResponsive Materials, EarlyView.
We reported a stress‐guided photo‐programming strategy that enables cholesteric liquid crystal elastomers (CLCEs) to achieve synchronous 3D shape morphing and structural color evolution from a single 2D film. Abstract Flexible materials with dynamic structural colors have attracted considerable interest for multilevel information interaction, showing ...
