Working-class males and engagement with high school education

This study explores working-class males' engagement with high school education as statistically this group are underachieving and the chosen city in the North-West of England has been highlighted as an area of particular concern. Questionnaires and semi-structured interviews were used in an attempt to establish which issues affected their engagement in school, allowing a critical insight into their attitudes towards education. Findings indicate that there are a range of factors causing the educational disengagement of working-class boys in the city, ranging from deprivation to the content of the curriculum. The combination of causes is complex and varies between individuals, although the most common obstacle seems to be relationships between teachers and participants, with the issue of ‘relate-ability’ particularly evident

The eta-inverted sphere over the rationals

We calculate the motivic stable homotopy groups of the two-complete sphere spectrum after inverting multiplication by the Hopf map eta over fields of cohomological dimension at most 2 with characteristic different from 2 (this includes the p-adic fields and the finite fields of odd characteristic) and the field of rational numbers; the ring structure is also determined.Comment: 24 pages, 6 figures, 4 tables.

An implementation of Sub-CAD in Maple

Cylindrical algebraic decomposition (CAD) is an important tool for the investigation of semi-algebraic sets, with applications in algebraic geometry and beyond. We have previously reported on an implementation of CAD in Maple which offers the original projection and lifting algorithm of Collins along with subsequent improvements. Here we report on new functionality: specifically the ability to build cylindrical algebraic sub-decompositions (sub-CADs) where only certain cells are returned. We have implemented algorithms to return cells of a prescribed dimensions or higher (layered {\scad}s), and an algorithm to return only those cells on which given polynomials are zero (variety {\scad}s). These offer substantial savings in output size and computation time. The code described and an introductory Maple worksheet / pdf demonstrating the full functionality of the package are freely available online at http://opus.bath.ac.uk/43911/.Comment: 9 page

The Domestic Market for Short-term Debt Securities

The market for short-term debt is dominated by the issuance of bank securities. Yields on these securities act as an important reference rate within the financial system. The turmoil in global markets during recent years has led to significant changes in the short-term debt market as the funding profiles of banks and other issuers of short-term securities has altered.short-term debt; prime banks; BBSW; ABCP; LIBOR; OIS

A computer simulation of oscillatory behavior in primary visual cortex

Periodic variations in correlated cellular activity have been observed in many regions of the cerebral cortex. The recent discovery of stimulus-dependent, spatially-coherent oscillations in primary visual cortex of the cat has led to suggestions of neural information encoding schemes based on phase and/or frequency variation. To explore the mechanisms underlying this behavior and their possible functional consequences, we have developed a realistic neural model, based on structural features of visual cortex, which replicates observed oscillatory phenomena. In the model, this oscillatory behavior emerges directly from the structure of the cortical network and the properties of its intrinsic neurons; however, phase coherence is shown to be an average phenomenon seen only when measurements are made over multiple trials. Because average coherence does not ensure synchrony of firing over the course of single stimuli, oscillatory phase may not be a robust strategy for directly encoding stimulus-specific information. Instead, the phase and frequency of cortical oscillations may reflect the coordination of general computational processes within and between cortical areas. Under this interpretation, coherence emerges as a result of horizontal interactions that could be involved in the formation of receptive field properties
