Finding Common Ground: The Role of Preventive Conservation in Response to the Expectations of Contemporary Audiences at the National Gallery,London

ABSTRACT

Like many museums and galleries following a prolonged period of austerity, the National Gallery has increased its public, private and corporate activities on an unprecedented scale and embarked on an extensive building programme to develop the site and its heritage-listed building. Together with an expanding loans and exhibitions programme, institutional attention has been drawn towards using the collection and building in ways not done before, both to attract new audiences and to develop new income sources. However, such new and escalating activities have the potential to expose the collection to risks not previously considered and are increasing cumulative exposure to certain environmental factors. A new group, the Preventive Conservation Working Group (PCWG), working at an operational level, has recently been established as a forum for discourse, collaboration and innovation at this time of transformation, and its activities and areas of current focus are presented. The role of this group in safeguarding the collection while helping the institution to respond to the expectations of modern life and the contemporary audience are discussed, as well as some of the other positive benefits resulting from the group's formation.     

The effects of added mass on the biomechanics and performance of countermovement jumps

This study examined the kinetic and temporal differences between countermovement jumps (CMJs) and eccentrically loaded CMJs. A survey of 109 coaches and athlete showed that 87% of respondents regularly used jumps with added mass within training. Sixteen male and thirteen female track and field athletes from sprinting, hurdling and jumping events performed 5 bodyweight CMJs 5 jumps wearing a weighted jacket and 5 eccentrically loaded dumbbell (LDB) jumps trials in a randomised order. Peak force (PF), peak power (PP), flight time (FT), concentric time (CON-T), eccentric time (ECT), total time (TIME) and eccentric/concentric ratio (E/C-Ratio) were obtained from force plate data. Statistically significant differences (p < 0.05) with moderate to large magnitude effect sizes were found between men and women in FT, PP and PF but not in any of the temporal variables. The results indicated that the WJ decreased FT in men (↓9%) and women (↓10%) but LDB jumps had similar FT to CMJ. Overall, the results showed that LDB increased the E/C Ratio (↑50% and ↑42%) and decreased CON-T (↓37% and ↓25%) compared with WJ and CMJ respectively. LDB jumping is not recommended as a training modality as it tends to disrupt the relative timing of the jump action.     

Bivariate functional principal components analysis: considerations for use with multivariate movement signatures in sports biomechanics

Sporting performance is often investigated through graphical observation of key technical variables that are representative of whole movements. The presence of differences between athletes in such variables has led to terms such as movement signatures being used. These signatures can be multivariate (multiple time-series observed concurrently), and also be composed of variables measured relative to different scales. Analytical techniques from areas of statistics such as Functional Data Analysis (FDA) present a practical alternative for analysing multivariate signatures. When applied to concurrent bivariate time-series multivariate functional principal components analysis (referred to as bivariate fPCA or bfPCA in this paper) has demonstrated preliminary application in biomechanical contexts. Despite this, given the infancy of bfPCA in sports biomechanics there are still necessary considerations for its use with non-conventional or complex bivariate structures. This paper focuses on the application of bfPCA to the force-angle graph in on-water rowing, which is a bivariate structure composed of variables with different units. A normalisation approach is proposed to investigate and standardise differences in variability between the two variables. The results of bfPCA applied to the non-normalised data and normalised data are then compared. Considerations and recommendations for the application of bfPCA in this context are also provided.     

A social neuroscience perspective on physical activity

The objective of this investigation was to examine the cognitive characteristics of individuals who demonstrate successful and unsuccessful self-regulation of physical activity behavior. In Study 1, participants articulated 1-week intentions for physical activity and wore a triaxial accelerometer over the subsequent 7 days. Among those who were motivated to increase their physical activity, those who were most and least successful were administered an IQ test. In Study 2, a second sample of participants completed the same protocol and a smaller subset of matched participants attended a functional imaging (fMRI) session. In Study 1, successful self-regulators (SSRs) scored significantly higher than unsuccessful self-regulators (USRs) on a test of general cognitive ability, and this difference could not be accounted for by favorability of attitudes toward physical activity or conscientiousness. In Study 2, the IQ effect was replicated, with SSRs showing a full standard deviation advantage over USRs. In the imaging protocol, USRs showed heavier recruitment of cognitive resources relative to SSRs in the anterior cingulate and orbitofrontal cortex during performance of a Stroop task; SSRs showed heavier recruitment in the right dorsolateral prefrontal cortex.     

What it means to be studying against the grain of neoliberalism in a community-based university programme in a ‘disadvantaged area’

Australia is indicative of a country that is deeply confused and conflicted around a policy discourse of inclusion that is sutured within an existential context heavily committed to the tenets of neoliberalism. Nowhere is this more evident than in the case of higher education, in which the proportion of young people from backgrounds of ‘disadvantage’ has remained implacably stuck at around 15% for several decades. The research from which this paper comes is an innovative community-based university-provided programme for young people for whom university education was never a realistic possibility – because of family histories, interruption to their lives, of having undertaken forms of secondary education that prevented them from gaining university entrance qualification, or who had terminated their education before completing the secondary years of schooling. This paper explores the story of one young person in his first year in a university programme, as he struggled with obstacles and impediments of a higher education system and set of neoliberal policy discourses that remain deeply sceptical and antagonistic to his trajectory.
