The life of Dr W. F. Hook with special reference to and assessment of his educational work

Chapter 1. Outlines his life commencing with his education and also his curacy at Whippingham, during which he studied theology intensively and began his pastoral work. His work at Moseley and Birmingham when his educational interest and close contact with the working classes first came to the fore. This work was continued on a larger scale at Coventry and then at Leeds. His relationship to The Tractarians is outlined and also his work of Church and School extension. Finally his literary and other work at Chichester is mentioned together with a brief assessment of his life. Chapter 2. Educational progress during Dr Hook’s lifetime. The Monitorial system, the rise of the Voluntary Societies and the beginnings of State aid for education. The rise of Training Colleges, School inspection and the Pupil-Teacher system. Increased State provision, management and conscience clause controversies, the Revised Code and events leading up to the Education Act of 1870. The 1870 Act with its sequel and other Educational developments 1800-1875. Chapter 3. A survey of the practical and theoretical educational work of Dr Hook throughout his Ministry with special reference to his letter to the Bishop of St David’s on the means of rendering more efficient the education of the people (1846). Dr Hook’s practical educational work is shown to be very comprehensive while his educational theory is shown to have changed considerably over the years. Chapter4. The impact of Dr Hook’s letter to the Bishop of St David’s (1846) on contemporaries as revealed in biographical material and reviews. A critique of the Reviews and also an assessment of Dr Hook’s educational proposals both in the light of the possible alternatives to his suggestions and also in view of what in fact did happen in educational practice after 1846 both before and after the Education Act 1870

Advanced flight deck/crew station simulator functional requirements

This report documents a study of flight deck/crew system research facility requirements for investigating issues involved with developing systems, and procedures for interfacing transport aircraft with air traffic control systems planned for 1985 to 2000. Crew system needs of NASA, the U.S. Air Force, and industry were investigated and reported. A matrix of these is included, as are recommended functional requirements and design criteria for simulation facilities in which to conduct this research. Methods of exploiting the commonality and similarity in facilities are identified, and plans for exploiting this in order to reduce implementation costs and allow efficient transfer of experiments from one facility to another are presented

The Role of Environmental Payments in Sustaining Farm Incomes: A Four Year Study of Farm Businesses in an Upland Area of the UK

A representative sample of both participant and non-participant case study farms was examined over a three-year period in the Shropshire Hills Environmentally Sensitive Area of the UK from 1997 to 2000. The effects on farm business viability were monitored and results compared with two relevant sub samples of Farm Business Survey recorded farms. The study showed that farming profitability declined sharply over the study period but that participant case study farm profitability exceeded that of non-participants by an average of £4024 per year. This was attributable to a combination of factors which included larger average farm size, the ESA premium and more intensive farming operations. Subsidies received by both types of farms were almost totally on the "per head" basis and averaged £270 per hectare. Without these both classes of farms would have been highly unprofitable. The status of the ESA premium compared with these figures was an average of 4.5 percent of business turnover or £2358 per farm, well below that of headage based subsidies. Return on capital invested in land was consistently low, suggesting that even with these levels of subsidies the long-term future of these farms could be uncertain. The results achieved were consistent with those obtained from the Farm Business Survey data provided for the two relevant sub-samples.Farm Management,

Gauge Field Preheating at the End of Inflation

Here we consider the possibility of preheating the Universe via the parametric amplification of a massless, U(1) abelian gauge field. We assume that the gauge field is coupled to the inflaton via a conformal factor with one free parameter. We present the results of high-resolution three-dimensional simulations of this model and show this mechanism efficiently preheats the Universe to a radiation-dominated final state.Comment: 8 pages, 8 figure

Real-world comparison of probe vehicle emissions and fuel consumption using diesel and 5 % biodiesel (B5) blend.

An instrumented EURO I Ford Mondeo was used to perform a real-world comparison of vehicle exhaust (carbon dioxide, carbon monoxide, hydrocarbons and oxides of nitrogen) emissions and fuel consumption for diesel and 5% biodiesel in diesel blend (B5) fuels. Data were collected on multiple replicates of three standardised on-road journeys: (1) A simple urban route; (2) A combined urban/inter-urban route; and, (3) An urban route subject to significant traffic management. At the total journey measurement level, data collected here indicate that replacing diesel with a B5 substitute could result in significant increases in both NOx emissions (8-13%) and fuel consumption (7-8%). However, statistical analysis of probe vehicle data demonstrated the limitations of comparisons based on such total journey measurements, i.e., methods analogous to those used in conventional dynamometer/drive cycle fuel comparison studies. Here, methods based on the comparison of speed/acceleration emissions and fuel consumption maps are presented. Significant variations across the speed/acceleration surface indicated that direct emission and fuel consumption impacts were highly dependent on the journey/drive cycle employed. The emission and fuel consumption maps were used both as descriptive tools to characterise impacts and predictive tools to estimate journey-specific emission and fuel consumption effects

Realizability of the Lorentzian (n,1)-Simplex

In a previous article [JHEP 1111 (2011) 072; arXiv:1108.4965] we have developed a Lorentzian version of the Quantum Regge Calculus in which the significant differences between simplices in Lorentzian signature and Euclidean signature are crucial. In this article we extend a central result used in the previous article, regarding the realizability of Lorentzian triangles, to arbitrary dimension. This technical step will be crucial for developing the Lorentzian model in the case of most physical interest: 3+1 dimensions. We first state (and derive in an appendix) the realizability conditions on the edge-lengths of a Lorentzian n-simplex in total dimension n=d+1, where d is the number of space-like dimensions. We then show that in any dimension there is a certain type of simplex which has all of its time-like edge lengths completely unconstrained by any sort of triangle inequality. This result is the d+1 dimensional analogue of the 1+1 dimensional case of the Lorentzian triangle.Comment: V1: 15 pages, 2 figures.

The disconnect between the current orthodoxy of local government and the promise and practice of information technology management: an illustrative case study

Information technology (IT) is often assumed to be a critical enabling factor for modern democratic processes. In this paper we examine some of the IT management issues that have arisen as a result of the changing nature of local government. We identify a disconnect between the current orthodoxy of local government, the expected benefits of information technology, and the actual experience of information technology management in public-sector organisations. Many public sector organisations suffer from multiple IT management problems that seriously affect their ability to deliver on the promise that information technology management will delivery the quality management information that that is required by increased demands for public accountability. We illustrate this with a case study

A tool for assessing error in digital elevation models from a user’s perspective

A Digital Elevation Model (DEM) is a representation of geographic reality. The elevations recorded within DEMs have been shown to contain errors pertaining to sampling, measurement and interpolation (Fisher, 1998). Even a small amount of elevation error can greatly affect derivative products (Holmes et al., 2000). This can potentially have a significant impact on the application of DEMs in Geographical Information Systems (GIS) where first and second order derivatives are considered

The a-number of hyperelliptic curves

It is known that for a smooth hyperelliptic curve to have a large $a$-number, the genus must be small relative to the characteristic of the field, $p>0$, over which the curve is defined. It was proven by Elkin that for a genus $g$ hyperelliptic curve $C$ to have $a_C=g-1$, the genus is bounded by $g<\frac{3p}{2}$. In this paper, we show that this bound can be lowered to $g <p$. The method of proof is to force the Cartier-Manin matrix to have rank one and examine what restrictions that places on the affine equation defining the hyperelliptic curve. We then use this bound to summarize what is known about the existence of such curves when $p=3,5$ and $7$.Comment: 7 pages. v2: revised and improved the proof of the main theorem based on suggestions from the referee.
