Key points
- It is more important to a funder to know that the research advances knowledge and has an impact on the field than that it is published in a prestigious journal (or not).
- Improving journal quality assurance is more important than improving the business model.
- Focusing on open access misses the point that journals need to improve their quality standards.

An investigation has been undertaken at St Andrew’s church, Walpole St Andrew, Norfolk, to establish the underlying causes of the observed stone decay to the upper parts of the six stone piers. The stone decay was first recorded in the early 1930s. The salt-contaminated masonry within the church has been shown to undergo severe salt decay during the summer, with little damage occurring over the winter months. The south aisle piers have been shown to decay 2.5 times faster than the north aisle piers. Although crystallization–hydration cycles have been identified, the rate of decay is at its greatest when the cycling is relatively infrequent. This was not the expected trend. Furthermore, it has been shown that during extended periods where the ambient relative humidity is less than 75%, the rate of decay reaches a maximum. It is the length of this ‘drying’ period that apparently has the greatest influence on the rate of decay and could explain the significant difference in the rate of decay between the south and north aisle piers. The results have serious implications for passive conservation, where it is often recommended to lower the ambient relative humidity to well below the equilibrium relative humidity of the salt contaminant, to avoid crystallization–hydration cycles. Since, at the time of building, the church was situated on the coast, it is possible that the sodium chloride contamination occurred during the building process (1440–1520), particularly since the area was prone to sea-flooding at this time. Alternatively, the salt could have been applied as a treatment during the general restoration of 1897. Whatever the source of the salt, it seems likely that the ambient environment was changed by the insertion of a sealed floor in 1897, which could account for the onset of the salt decay. 相似文献

This article follows an earlier publication highlighting the changing role of special educational needs co‐ordinators (SENCos) in England. SENCos are now required to manage change strategically and deliver inclusive school cultures. School‐based action research undertaken by a teacher studying for the postgraduate National Award for SEN Co‐ordination (NASENCO) is featured in the article; a strategic review of resource allocation increased the availability and quality of interventions for students with special educational needs and disabilities (SEND). The commentary which frames the study acknowledges that many SENCos are not yet members of a senior school management team (SMT) despite their mandated strategic whole‐school remit. Featuring the process through which one SENCo has strived to enhance SEND provision and develop context‐specific key performance indicators brings official guidance on the SENCo's role in strategic change management into sharp focus, raising questions that should concern both SMTs and non‐SMT SENCos. 相似文献

Classroom discourse patterns were examined in the morning news sessions of a primary school classroom. The effects of reducing teacher questions and increasing rates of teacher pauses, praise and directives were investigated. Child words spoken and child expansions were recorded, as well as class call‐outs and teacher control statements. Frequencies of child words spoken showed no significant changes across the phases of the study. However, reducing teacher questions and increasing teacher pauses significantly decreased child expansions, while reducing teacher questions and increasing teacher praise significantly increased child expansions. Replacing teacher questions with directives had no significant effect upon child expansions. Class call‐outs and teacher control statements showed no significant changes across the intervention phases. The results of this study suggest that, for this teacher and class, teacher questions may be decreased without adversely affecting either child utterances or class behaviour, and that replacing questions with praise may increase children's contributions — particularly in the form of verbal expansions — to morning news talks. 相似文献

Two experiments investigated the use of orthographic analogies in 6 year olds. In Experiment 1, 26 children were shown CVC clue and target word pairs sharing either rimes (`fork' – `pork'), heads (`fork' – `ford') or were controls (`fork' – `hurl'). A modest advantage for rime-clued over head-cluedtargets was unreliable over by-subject and by-item analyses. Improvements in target word reading were correlated with pretest scaffolding errors (e.g. `pork' misread as `park'). In Experiment 2, 50 children were pretaught three clue words for each target word before being shown words that shared either rimes (`leak' – `peak'), or medial vowel digraphs (`leak') – `bean'), or were controls (`leak' – `herd'). A modest advantage for rime-clued over vowel digraph-clued targets was again unreliable over by-subject and by-item analyses. Neither rime nor phoneme awareness measures were correlated with rime inference use. Vowel, but not rime inference, was correlated with scaffolding errors. Rime detection was the strongest predictor of reading ability, whereas phoneme segmentation was the strongest predictor of the use of scaffolding errors. 相似文献

This article reports on how an action research strategy was used to increase children's uptake of feedback during peer assessment in primary school writing. Several different strategies were used in the study that had been successful in increasing students’ uptake of peer feedback in contexts such as higher education. In order to evaluate how successful these actions were, several different data collection methods were drawn upon to triangulate findings including children's work, observations, informal interviews and mind mapping. Thematic analysis was used to analyse the data generated. Findings are consistent with those from research in other settings which suggest that pupils make better use of feedback if: it is task-involving and useful; there is sufficient time given for them to act on it and discuss it with their peers; and they are asked to reflect on how it has been used to improve the quality of the assessed work. 相似文献
