Music education

Prior to the 1980s the music curriculum consisted of class-singing, sol-fah deciphering and music appreciation. Typical resources were the piano, the Curwen modulator, numerous sets of song and sight-reading books (to suit single gender class groupings) and a record player. More enlightened teachers would have some percussion instruments or recorders in the classroom and, from the 1970s, the odd guitar. The Scottish Examination Board 'O' Grade examination at the end of year 4 was designed to be overtaken by pupils who had expertise on an instrument or voice to the equivalent of Associated Board Grade 5, tuition on which was given outwith the classroom while the teacher concentrated on historical study, rudiments and analysis. Such elitism fuelled growing disillusionment in pupils and many teachers who experienced a different world of music in their private lives (Witkin, 1974). Significant and effective change came in 1978 with the publication by the Scottish Education Department of the highly controversial Curriculum Paper 16, Music in Scottish Schools. This was the dividing line between past practices and future developments which radically changed the way in which music was taught and which clearly focused music teachers' and educators' energies and ideas. It encapsulated many of the ideas and innovations which had been forming in Britain through the work of Paynter and Aston (1970), Witkin (1974) and in the USA since the 1960s (Choksy et al., 1986) and placed them into a Scottish context. This provided the impetus for a root and branch overhaul of the curriculum which would reshape music in the classroom into an action-based experience, open to all children, regardless of their musical or academic ability. In the contexts of both primary and secondary schools, Curriculum Paper 16 recommended syllabus content and teaching and learning strategies, the review of assessment approaches and most significantly, staffing, resource and accommodation requirements to enable 'music for all' to be implemented. These recommendations gave teachers and headteachers the tools and impetus to make demands on local authorities to fund the developments appropriately

Flow over a cylinder subjected to combined translational and rotational oscillations

The experimental research reported here employs particle image velocimetry to extend the study of Nazarinia et al. (2009a), recording detailed vorticity fields in the near-wake of a circular cylinder undergoing combined translational and rotational oscillatory motions. The focus of the present study is to examine the effect of the ratio between the cross-stream translational and rotational velocities and frequencies on the synchronization of the near- wake structures for multiple phase differences between the two motions. The frequencies are fixed close to that of the natural frequency of vortex shedding. The results are presented for a fixed amplitude of rotational oscillation of 1 rad and a range of ratios between the translational and rotational velocities ðVRÞ 1⁄4 1⁄20:25,0:5,1:0,1:

Harnessing Electrical Power from Vortex-Induced Vibration of a Circular Cylinder

The generation of electrical power from Vortex-Induced Vibration (VIV) of a cylinder is investigated numerically. The cylinder is free to oscillate in the direction transverse to the incoming flow. The cylinder is attached to a magnet that can move along the axis of a coil made from conducting wire. The magnet and the coil together constitute a basic electrical generator. When the cylinder undergoes VIV, the motion of the magnet creates a voltage across the coil, which is connected to a resistive load. By Lenz's law, induced current in the coil applies a retarding force to the magnet. Effectively, the electrical generator applies a damping force on the cylinder with a spatially varying damping coefficient. For the initial investigation reported here, the Reynolds number is restricted to Re < 200, so that the flow is laminar and two-dimensional (2D). The incompressible 2D Navier-Stokes equations are solved using an extensively validated spectral-element based solver. The effects of the electromagnetic (EM) damping constant xi_m, coil dimensions (radius a, length L), and mass ratio on the electrical power extracted are quantified. It is found that there is an optimal value of xi_m (xi_opt) at which maximum electrical power is generated. As the radius or length of the coil is increased, the value of xi_opt is observed to increase. Although the maximum average power remains the same, a larger coil radius or length results in a more robust system in the sense that a relatively large amount of power can be extracted when xi_m is far from xi_opt, unlike the constant damping ratio case. The average power output is also a function of Reynolds number, primarily through the increased maximum oscillation amplitude that occurs with increased Reynolds number at least within the laminar range, although the general qualitative findings seem likely to carry across to high Reynolds number VIV

Modification of three-dimensional transition in the wake of a rotationally oscillating cylinder

A study of the flow past an oscillatory rotating cylinder has been conducted, where the frequency of oscillation has been matched to the natural frequency of the vortex street generated in the wake of a stationary cylinder, at Reynolds number 300. The focus is on the wake transition to three-dimensional flow and, in particular, the changes induced in this transition by the addition of the oscillatory rotation. Using Floquet stability analysis, it is found that the fine-scale three-dimensional mode that typically dominates the wake at a Reynolds number beyond that at the second transition to three-dimensional flow (referred to as mode B) is suppressed for amplitudes of rotation beyond a critical amplitude, in agreement with past studies. However, the rotation does not suppress the development of three-dimensionality completely, as other modes are discovered that would lead to three-dimensional flow. In particular, the longer-wavelength mode that leads the three-dimensional transition in the wake of a stationary cylinder (referred to as mode A) is left essentially unaffected at low amplitudes of rotation. At higher amplitudes of oscillation, mode A is also suppressed as the two-dimensional near wake changes in character from a single- to a double- row wake; however, another mode is predicted to render the flow three-dimensional, dubbed mode D (for double row). This mode has the same spatio-temporal symmetries as mode A

Maintaining and Improving Irrigation Application Uniformity in Sprinkler and Drip Systems

The goal of most irrigation system design and management is to provide all plants in an irrigated area with equal access to water. Ideally, each plant should receive the exact amount of water it needs. If a field needs 1 inch of water for irrigation, all parts of the field should receive exactly that. The reality is not so perfect. It is practically impossible to apply the same quantity of water to all plants in an irrigated area, plot, or field. In other words, all irrigation systems have some nonuniformities in the water delivered. Instead of designing and managing irrigation systems to apply water 100% uniformly, the goal of irrigation system designers, manufacturers, and operators should be to maximize irrigation uniformity within practical and economic constraints. In this fact sheet, we explain the major causes of uneven water distribution in sprinkler and drip irrigation systems and suggest ways to improve or maintain uniformity

Special Section Introduction: Mass Observation as Method

Since Mass Observation's foundation in 1937, the organisation has played witness to the great and the small events of everyday life during the last eight decades, recording people's opinions, beliefs and experiences, and making them available for researchers to develop new interpretations of British social life. Although the data produced is often messy and unwieldy and apparently contradicts many sociological assumptions about methodological rigour, the Archive is uniquely placed to offer detailed and exceptionally rich accounts of the fibre of everyday life and to reveal the deep complexities of family, personal and intimate life. As Mike Savage notes in Identities and Social Change in Britain since 1940, 'Mass-Observation is the most studied, and arguably the most important, social research institution of the mid-twentieth century' (Savage 2010: 57). He situates this significance in it providing the focus for the emergence of a new intellectual class in late 1930s Britain of people who identified with a social scientific outlook. Until that point in time, the main point of entry into intellectual circles for newly educated classes was through literary culture, which was often implicitly elitist and hierarchical in its attitude to wider society
