Purpose – This chapter presents an analysis of a researcher-led follow-up activity during an early childhood reading lesson that was aligned with a gradual release of responsibility (GRR) model. Particularly, the authors seek to understand how students used their language(s) in this lesson, how they described particular linguistic decisions, and how language could be further conceptualized in such events.

Design/Methodology/Approach – The authors develop a telling case (Mitchell, 1984) from the guided instruction portion of a lesson to make salient theoretical connections between metacognitive strategies taught in early literacy and metalinguistic knowledge theorized from the field of linguistic anthropology. The lesson was video recorded for interactional analysis. The video recording was also used to stimulate recall and allow students to reflect on their own language use.

Findings –Through the telling case, the authors use language socialization as a lens to understand the way students represent story retell with physical objects. Though some students do not use the school-based conventionalized form of retelling, they do engage in retelling by using a variety of other forms. The authors highlight through the case that the metacognitive strategy of story retell is distinct from the abstract linear, left-to-right representation of sequencing of events.

Research Limitations/Implications – This study suggests that further attention is needed to theorize the relationship between reading strategies and forms of representation in multilingual preschool contexts. In particular, the very notions of literacy and language need to be nuanced through conversations among multiple disciplines.

Practical Implications – Practitioners are encouraged to attend to the differences between metacognitive strategies that are useful for reading comprehension and the expected styles of representation. Teachers can consider leveraging the communicative repertoires of emergent bilingual students as they accomplish early literacy activities, thereby, potentially offering further scaffolds for learning reading strategies.

Originality/Value of Paper – This chapter brings nuance to the GRR model by demonstrating that there is a difference between the GRR of metacognitive strategies in reading instruction and the way they are represented through diverse semiotic repertoires.

IT was not until the Battle of Britain that Hawker Aircraft Ltd. found, like so many other aircraft firms, that pre‐war repair methods were unsuitable for dealing with the variety and quantity of work which resulted from large‐scale engagements in the air. They discovered that not only were new types of repairs needed but also that more attention had to be paid to the speedy distribution of repair information.

THAT spar repairs were indeed needed, and not only for repairing damage caused by bullets, shells and “flak”, is evidenced by the fact that on one occasion a Hurricane had the bottom boom of the front spar severed when it flew into a balloon cable. Fortunately, the cable broke and the pilot succeeded in flying the aero‐plane back to his station. The wing was satisfactorily repaired at Hawker's Homewood works; some idea of the extent of the damage will be gained from FIG. 11.

THE policy and organization of the Avro Repair Group was based upon intelligent anticipation—anticipation of the many and varied types of damage that might be expectedl anticipation of quantities, and anticipation of facilities to deal with all contingencies. The central depot at Bracebridge Heath, Lincoln, developed from an ex‐1914–18 war hangar to an establishment employing nearly 3,000 men and forming the hub of an organization that embraced many stations and subcontractors' works, civilian out‐working parties, of A. V. Roe personnel, effected a high proportion of major repairs to Lancaster, York and Anson aircraft; such parties were stationed all over the British Isles and were supplemented by a fleet of some seventy mobile workshops.

THE medical problems of flying were first seriously tackled during the latter part of the first world war, when it became obvious that mechanical construction was indivisible with pilot performance. Research has since proceeded along two main lines: pre‐selection of personnel for flying duties and the maintenance of the physiological efficiency of flying personnel. There is no doubt that the work accomplished is proving invaluable in these times of extended air force expansion and added interest is therefore given to the report of the symposium held at Washington D.C., at which Air‐Commodore H. E. Whittingham represented Great Britain.

The purpose of this paper is to develop a quantitative model to assess probability of errors and errors correction costs in parts feeding systems for assembly lines.

Event trees are adopted to model errors in the picking-handling-delivery-utilization of materials containers from the warehouse to assembly stations. Error probabilities and quality costs functions are developed to compare alternative feeding policies including kitting, line stocking and just-in-time delivery. A numerical case study is included.

This paper confirms with quantitative evidence the economic relevance of logistic errors (LEs) in parts feeding processes, a problem neglected in the existing literature. It also points out the most frequent or relevant error types and identifies specific corrective measures.

While the model is general purpose, conclusions are specific to each applicative case and are not generalizable, and some modifications may be required to adapt it to specific industrial cases. When no experimental data are available, human error analysis should be used to estimate event probabilities based on underlying modes and causes of human error.

Production managers are given a quantitative decision tool to assess errors probability and errors correction costs in assembly lines parts feeding systems. This allows better comparing of alternative parts feeding policies and identifying corrective measures.

This is the first paper to develop quantitative models for estimating LEs and related quality cost, allowing a comparison between alternative parts feeding policies.

The foundation collection of the printed books now forming the Library of the British Museum was that of Sir Hans Sloane. This comprised about 40,000 volumes. To it was added in 1759 the Royal collection, begun in the time of Henry VII and inherited by George II from his predecessors on the throne.

In the first part of the paper, which outlines the laboratory and field investigations on corrosion by flue gases from solid fuel combustion carried out by the British Coal Utilisation Research Association, the effects of different flue gas constituents on corrosion phenomena are discussed. Laboratory studies of the effects of fuel type and method of combustion on the sulphuric acid content of combustion gases are described. The second part presents the results of measurements of the condensation characteristics of flue gases from water‐tube boilers in power stations and from various industrial boilers and furnaces; investigations into the use of additives are described briefly. The final section is concerned with some theoretical considerations of effects of fuel type, burning rate, etc., on the amounts of sulphuric acid likely to be present in the combustion products from domestic appliances.

In this, the concluding part of Mr. Kear's paper, methods of reducing corrosion by flue‐gas condensates are discussed, including fuel selection, the addition of ‘inerts,’ dusts and smokes. But it is the removal of the root causes of low‐temperature corrosion which is the preferred method.
