Mr R. H. Collins, of Harold Cartwright Grammar School, Solihull, told the conference of current progress in bringing a new ‘O’‐level syllabus in Mathematics into operation. Over the years an ever‐widening gulf had been developing between the mathematics taught in schools and that taught in the universities, colleges of technology and used in industry and life in general. We have always forced children to follow adult ways of reasoning — very different from their own; now a child‐centred mathematics was required in which whatever is being developed as a topic must have roots in the immediate and past experience of the children.

The BP Conferences Mathematics. The first of the BP conferences examined the problems arising in the teaching of mathematics and referred to the use mad: of mathematics, in its widest applications, by industry. It was attended by about 50 mathematics masters from all parts of Great Britain, chiefly from public and grammar schools, but representing also other schools and colleges of technology.

Mr Thomas, who is a member of the FBI Education Committee, chairman of the FBI Technical Colleges Committee, member of the BISF Training Committee, and of the West Riding and North Derbyshire Area Training Committee, BISF, discusses two important topics arising in Sir Eric's book: the government of colleges of technology, and the nature of liberal studies.

High‐Production ‘Vacu‐Blast’. A new form of gun has been introduced by the manufacturers of Vacu‐Blast, specially designed to obtain an extremely high rate of millscale removal from flat plate prior to fabrication. Indeed, the manufacturers claim that millscale can be removed with the gun at a rate varying between 300 and 600 sq.ft. /hr., according to the surface to be cleaned.

Visual representations of teachers and teachers’ work over the past century and a half, in both professional literature and popular media, commonly construct teachers’ work as teacher‐centred, and built around specific technologies that privilege the teacher as the active, dominant and legitimate principal agent in the educational process. This article analyses a set of photographs that represent an ‘alternative’ educational approach to normalised mainstream schooling, to explore the ways such practices might enact pedagogy within different social relations. Butler’s discussions of performativity and Foucault’s concept of technologies of self, offer a theoretical framework for understanding the educative and political work such visual representations of teachers work might perform, in the construction of capacities to imagine what teachers’ work looks like, with implications for capacities to enact teaching. The photographs analysed present a pedagogy in which the teacher is less visibly central and less overtly directive in relation to children’s learning than in normalised pedagogy. Thus, in important respects, they offer material from which to construct a different vision of what teachers’ work looks like, and, consequently, to enact teachers’ work differently. In this article I explore a set of photographs of Montessori methods at Blackfriars School in Sydney in the early twentieth century. I do so in order to establish whether such photographs offer a representation of teaching that differs significantly from conventional ‘normalised’ understandings of teachers’ work. This in turn is intended to inform one part of a transformative agenda to address problematic aspects of contemporary schooling.

Current solutions for monitoring the progress of pavement construction (such as collecting, processing and analysing data) are inefficient, labour-intensive, time-consuming, tedious and error-prone. In this study, an automated solution proposes sensors prototype mounted unmanned ground vehicle (UGV) for data collection, an LSTM classifier for road layer detection, the integrated algorithm for as-built progress calculation and web-based as-built reporting.

The crux of the proposed solution, the road layer detection model, is proposed to develop from the layer change detection model and rule-based reasoning. In the beginning, data were gathered using a UGV with a laser ToF (time-of-flight) distance sensor, accelerometer, gyroscope and GPS sensor in a controlled environment. The long short-term memory (LSTM) algorithm was utilised on acquired data to develop a classifier model for layer change detection, such as layer not changed, layer up and layer down.

In controlled environment experiments, the classification of road layer changes achieved 94.35% test accuracy with 14.05% loss. Subsequently, the proposed approach, including the layer detection model, as-built measurement algorithm and reporting, was successfully implemented with a real case study to test the robustness of the model and measure the as-built progress.

The implementation of the proposed framework can allow continuous, real-time monitoring of road construction projects, eliminating the need for manual, time-consuming methods. This study will potentially help the construction industry in the real time decision-making process of construction progress monitoring and controlling action.

This first novel approach marks the first utilization of sensors mounted UGV for monitoring road construction progress, filling a crucial research gap in incremental and segment-wise construction monitoring and offering a solution that addresses challenges faced by Unmanned Aerial Vehicles (UAVs) and 3D reconstruction. Utilizing UGVs offers advantages like cost-effectiveness, safety and operational flexibility in no-fly zones.

Pictures are routinely identified as possible sources for researching history yet they are widely either neglected or underused. This article explores the use of pictorial materials, in particular photographs, in historical analysis. It describes some common, or standard, uses of photographs in historical writing, and critically discusses them. It identifies and examines methodological and ethical issues in using photographs as evidence. And it draws on a current project which is using a rich body of photographs as an integral part of its analysis of the history of one educational institution to explore these issues

The purpose of this paper is to analyze the effects of the PRD geometric parameters, including the area and aspect ratio, on the discharge and force characteristics of pressure relief process under various plenum compartment pressures and Mach numbers.

Under various plenum compartment pressures and Mach numbers, the effect of the area and aspect ratio on the discharge and force characteristics of the PRD are numerically investigated via a three-dimensional steady Reynolds-averaged Navier–Stokes equations solver based on structured grid technology.

When the aspect ratio remains constant, the discharge coefficient C_D, thrust coefficient C_T and moment coefficient C_M are not affected by the PRD. When the area is constant, the aspect ratio dramatically impacts the discharge and force characteristics because the aspect ratio increases, the discharge coefficient C_D of the PRD decreases, and the thrust coefficient C_T and the moment coefficient C_M both increase. When the aspect ratio is 2, the discharge coefficient C_D decreases by 14.7 per cent, the thrust coefficient C_T increases by 10-15 per cent, and the moment coefficient C_M increases by 10-23 per cent compared with when the aspect ratio is 1.

This study provides detailed data and conclusions for nacelle PRD researchers and actual engineering applications.

On the basis of considering the influence of operating conditions on the discharge and force characteristics of the nacelle PRD, the impact of geometric parameters, including the area and aspect ratio on the discharge and force characteristics is comprehensively considered.

The literature of entrepreneurship has an urban focus and despite the emergence of the rural entrepreneurship literature, we know little about the characteristics, philosophies, operating practices and growth strategies of ordinary village entrepreneurs’ in a UK context. As a concept, the “village entrepreneur” is contentious as theoretically there should be little difference between urban and rural entrepreneurs. Nevertheless, there is! The concept is important because many villages are in decline and are marginal places in terms of entrepreneurial opportunity. The paper aims to discuss these issues.

A review of the fragmented literature is conducted to synthesise and develop greater understanding. Drawing on a “life-story” approach the empirical strand comprises of an analysis of five ethnographic interviews with village entrepreneurs.

The respondents did not consider themselves entrepreneurs whom they characterised as flash, rogues and even crooked. Their embedded village entrepreneur persona was constructed around tales-of-character, hard work and perseverance. They prided themselves in making “slow-money” which they retain over their lifetime. Embeddedness, self-efficacy, character and morality were key themes encountered.

From a research perspective the findings are based on a limited sample and the study was not specifically designed to capture data on characteristics, philosophies and operating practices. Further research on a larger scale is necessary to validate the findings.

From a practical perspective policy makers require to consider the notions of embeddedness, self-efficacy, character and morality when considering implementing growth strategies in rural areas.

This study contributes to the growing literature of rural entrepreneurship by expanding the typology of rural entrepreneurs and by detailing philosophies, operating practices, and growth strategies suitable and appropriate for small village and rural businesses.

Outlines previous research on the effects of insider trading on share prices and reactions to the tightening up of US laws against illegal trading. Calculates returns for a sample of large managerial purchases made after the new legislation (1993‐1995) and announced in the Wall Street Journal to test for the presence of asymmetric information, agency conflicts and undervaluation; using firm size, market‐to‐book ratio, Q ratio and price‐earnings ratio as proxies. Finds that share prices react positively to large managerial purchases, especially if the firm is small, undervalued and/or experiencing conflicts between managers and shareholders; and that this effect is not reversed within a year.
