Methods Used with a High Ability Group

Teaching for social justice in a standards-driven social studies classroom can be challenging. However, the authors believe that there does not have to be a choice between meeting standards versus meeting the needs of students. Through semistructured interviews with four current social studies practitioners, the authors found similarities in the language the teachers used to describe the role of standards in their classrooms, teachers' perceptions of context as being important to the tension between teaching for social justice and teaching to standards, and the ways that perception impacted how they negotiated that tension. The authors offer social studies teachers an alternate conceptual frame for viewing social justice instruction in terms of methods rather than content.     

Demand for gambling: development and assessment of a gambling purchase task

Self-report purchase tasks are a novel approach examining the reinforcing value of addictive behaviour relative to increasing monetary costs required to access the addictive behaviour (i.e. demand). These measures reveal a positive relationship between the indices of demand and addiction problem severity and can elucidate factors associated with motivation for substance use. Gambling is an addictive behaviour that has not been examined using this paradigm. This study seeks to adapt and examine the purchase task for gambling behaviour. A gambling purchase task was devised that asked individuals how often per month they would gamble at various cover charges. Participants were 73 adults from the community with either gambling disorder (n = 28) or alcohol use disorder (n = 24) or were a healthy control (n = 21). Both the alcohol and gambling purchase tasks were administered. Results demonstrate discriminant validity of the gambling purchase task, as individuals with gambling disorder have significantly greater demand for accessing gambling than other groups. The alcohol purchase task also evidenced discriminant validity in that individuals with alcohol use disorder have significantly greater demand for alcohol than other groups. These findings support the use of the gambling purchase task to assess the demand for gambling.     

Squirrels in suburbia: influence of urbanisation on the occurrence and distribution of a common exotic mammal

Urbanisation is widely considered to promote the establishment of non-native species, but there is limited empirical evidence of the ecological factors driving their responses. The grey squirrel Sciurus carolinensis (Gmelin 1788) is native to North America, but is widespread in the UK and is starting to spread across Europe. It is regarded as one of the world’s worst invasive animals due to its adverse impacts on native biodiversity. We use the non-native grey squirrel population in Sheffield (UK) as a case study to assess which factors limit its distribution and abundance in urban environments. In 2010 the city-wide population of adult squirrels peaked at an estimated 6539 in autumn (0.46 squirrels/ha), with maximum local densities of 8.29/ha. These densities appear to be slightly lower than those recorded in urban environments in the species’ native range. Grey squirrels occurred more frequently at urban sites with larger amounts of green-space in the surrounding region. Local habitat characteristics were, however, more powerful predictors of urban grey squirrel occurrence and abundance than regional availability of green space. Canopy cover, seed bearing trees and supplementary feeders, provided for garden birds, positively influenced grey squirrels. The potential for grey squirrels to connect city dwellers with nature thus appears to be highest in urban locations that have considerable capacity to support native biodiversity. The beneficial impacts of supplementary feeding on grey squirrel populations is notable given concerns that squirrels can adversely influence bird populations. These habitat associations also imply that grey squirrels typically respond negatively to urbanisation, which challenges arguments that urbanisation favours exotic species.     

Involving carers from minority ethnic backgrounds in carer-led research

This qualitative pilot study investigated the interest of minority ethnic informal carers, with no previous experience of research, in engaging in carer-led research. Individual face-to-face interviews and focus groups were conducted to explore the understanding and attitudes carers hold to research alongside the motivators and de-motivators to their involvement in carer-led projects. The findings reveal that carers are interested in initiatives with a practical beneficial outcome for carers or those they look after. Black and minority ethnic carers identified interpreter and translation resources, gender sensitivity and flexibility around their involvement as major considerations. Carers’ perceptions of their transferable skills from personal or professional experiences to research were also closely linked to their willingness to engage in carer-led studies.     

Boundary oscillations: Epistemological and genre transformation during the 'method' of thesis writing

In this article I offer an account of some of the 'boundary oscillations' I experienced during the writing of my doctoral thesis, and attempt to illustrate my personal struggle with the presentation of qualitative data. This struggle evolved through my search for an appropriate style to [re]present both voice and experience as a text, resulting in my turning towards genres alternative to those normally adopted in social science research. And it was during that process that I experienced both change and conflict in my epistemological position, as I moved from positivism, through postpositivism and towards postmodernism.     

Measure for measure: evaluating performance and the arts organisation

This paper discusses the cultural policy and impacts of the application of performance indicators to subsidised arts organisations in Britain. The context of this study is the increased accountability and measurement of the outputs of arts organisations by government funding agencies, and the related drive for improved productivity and efficiency. In an extension of performance measurement regimes in ‘public good’ provision, and the arguments concerning economic importance of the cultural industries, the performing arts occupy an uncomfortable place as a pre-industrial activity being subjected to notions of economic efficiency. This discussion concerns the focus for analysis of the measurements used – the three-Es of economy, efficiency and effectiveness - and the rationale underlying their imposition. The outputs and performance indicators of the major subsidised arts organisations are then presented, based on a ten year time series, revealing declining audiences and production, but increasing ticket prices and expenditure, which arguably undermines the performing arts ‘merit good’ status.     

Difference-based Methods for Truncating the Singular Value Decomposition

Given a noisy time series (or signal), one may wish to remove the noise from the observed series. Assuming that the noise-free series lies in some low-dimensional subspace of rank r, a common approach is to embed the noisy time series into a Hankel trajectory matrix. The singular value decomposition is then used to deconstruct the Hankel matrix into a sum of rank-one components. We wish to demonstrate that there may be some potential in using difference-based methods of the observed series in order to provide guidance regarding the separation of the noise from the signal, and to estimate the rank of the low-dimensional subspace in which the true signal is assumed to lie.
