This paper responds to a trend of contracting out subjective well-being econometrics to demonstrate social return on investment (SROI) for evidence-based policy-making. We discuss an evolving ecology of ‘external’ research taking place ‘between’ the academy and commercial consultancy. We then contextualise this as waves of research methodologies and consultancy for the cultural sector. The new model of ‘external between’ consultancy research for policy is not only placed between the University and the market, but also facilitates discourse between policy sectors, government, the media and the academy. Specifically, it enables seductive but selective arguments for advocacy that claim authority through academic affiliation, yet are not evaluated for robustness. To critically engage with an emergent form of what Stone calls ‘causal stories’, we replicate a publicly funded externally commissioned SROI model that argues for the value of cultural activities to well-being. We find that the author’s operationalisation of participation and well-being are crucial, yet their representation of the relationship problematic, and their estimates questionable. This case study ‘re-performs’ econometric modelling national-level survey data for the cultural sector to reveal practices that create norms of expertise for policy-making that are not rigorous. We conclude that fluid claims to authority allow experimental econometric models and measures to perform across the cultural economy as if ratified. This new model of advocacy research requires closer academic consideration given the changing research funding structures and recent attention to expertise and the contracting out of public services.  相似文献

This study examined the psychometric properties of a questionnaire developed with the guidance of the socialization model of child behaviour to understand modifiable correlates of toddlers’ physical activity and sedentary behaviour. Findings are based on 118 parents (33.7 ± 4.9 years; 86% female) of toddlers (19.3 ± 2.7 months; 48% female) from Edmonton, Canada in The Parents’ Role in Establishing healthy Physical activity and Sedentary behaviour habits study (PREPS). The PREPS questionnaire encompassed 21 variables across the constructs of the socialization model of child behaviour. Of the nine variables assessed for internal consistency reliability, eight had good (α ≥ 0.70) reliability. Of the 15 continuous variables assessed for 1-week test–retest reliability, 10 had moderate (intra-class correlation = 0.50–0.74) and 5 had good (intra-class correlation ≥ 0.75) reliability. Of the six categorical variables assessed for 1-week test–retest reliability, two had fair (К = 0.21–0.40), one had moderate (К = 0.41–0.60), one had substantial (К = 0.61–0.80), and two had almost perfect (К = 0.81–1.00) reliability. Of the 12 sedentary behaviour variables assessed for convergent validity, 7 were significantly correlated with children’s screen time, of which three were small (r ≤ 0.29), two were medium (r = 0.30–0.49), and two were large (r ≥ 0.50) effect sizes.  相似文献

What values do theatre and dance hold for audience members? And how do these values differ between subsidised, amateur, and commercial performance? This paper addresses these questions through a survey of over 1800 spectators for theatre and dance in Tyneside in northeastern England, as well as a parallel set of focus groups, in the spring of 2014. These methods, which are designed for comprehensiveness and comparability, are being used across Europe by the Project on European Theatre Systems, a working group of theatre sociologists. Our research showed two sets of values which performances achieved; one was a common measure of performance quality, while the other described the values particular to subsidised work. This allows us to articulate both the general value of the arts and the particular values which subsidy (attempts to) facilitate. This has implications for both understandings of cultural value and for cultural policy, as the distinction between the two groups was not clean. We also found that amateur theatre participated in the same value system, but with an increased emphasis on loyalty and community cohesion. The paper concludes a methodological reflection on the use of quantitative methods in theatre studies.  相似文献

手机电视被称为新媒体先锋,一路走来,受到了业界的青睐,北京、上海和广州等地的媒体纷纷上马手机电视业务,以期抢占潮头,争夺先机。其实,任何一种媒体的诞生及其生命力,都要通过传播效果来反观,受众作为影响传播效果的重要因素,向来受到传播学者关注。手机媒体想在媒体生态中获得一席之地,并求得更好的发展,必须从受众因素分析入手,探求其必要性和可行性。  相似文献

略论运动生物力学的研究方法与测量技术   总被引:4,自引:0,他引:4  
文章认为:1,仅依靠牛顿分析力学的研究方法,运动生物力学只能停留在“研究人体机械运动规律”的水平,“走出系统”的研究方法适合于对活体系统的生物力学研究;2,“理论模型”需数据支持才具有应用价值,“数据模型”需相应的数学化才具有理论意义;3,活体运动过程的测量应建立参数采集与测量的标准化和参数分析与评价的专家系统;4,应界定常规参数和敏感参数,并区别参数间的平行关系和因果关系,测量精度的提高主要应依靠测量参数数字化过程的分析方法的进步。  相似文献
