The paper makes a connection between transmission modes and constructivism in sociology and education, respectively. There are parallels between Archer’s criticism of upward and downward conflation in social theory, and approaches to learning in education. In her 2012 book, Archer seeks to reconceptualise socialisation as relational reflexivity. This paper seeks to connect this idea to thinking about learning in relational terms and links the analysis to Young’s account of ‘bringing knowledge back in’. The paper uses an example from field work on participation in learning to provide concrete examples that illuminate the points being made. It argues that learning theory needs to move away from transmission and the constructivists’ ideas about education and to consider the relational aspects of learning.  相似文献

Recent years have witnessed a noticeable proliferation in Digital Library Systems (DLSs) and their specialized form represented in Digital Heritage Resources (DHRs). DHRs usually manage a complex and varied mix of digital heritage objects of different types and formats. They tend to be complex in nature and usually involve complex, simultaneous and intersecting workflows. As a result, DHRs impose implementation challenges on any solutions that aim to manage their workflows. Thus, despite the proliferation of DHRs, it is a noteworthy trend that there is a general lack of workflow management solutions that can be utilized in such systems. As a research area that is rarely covered, this paper therefore presents the design and development of a novel Workflow Management System (WfMS) built to integrate with DHRs specifically, and DLSs in general. In this context, an experimental WfMS aimed to test the validity of workflow management integration with DHRs. The devised WfMS was built as a workflow management solution that can adequately address the specific hurdles imposed by DHR implementations. Additionally, a novel DHR implementation framework called DISPLAYS (Digital Library Services for Playing with Antiquity and Shared Heritage) is presented as a test bed for the proposed WfMS.  相似文献

Abstract

This study is the first empirical investigation that has explored levels of athletic identity in elite-level English professional football. The importance of understanding athletes’ psychological well-being within professional sport has been well documented. This is especially important within the professional football industry, given the high attrition rate (Anderson, G., & Miller, R. M. (2011). The academy system in English professional football: Business value or following the herd? University of Liverpool, Management School Research Paper Series. Retrieved from http://www.liv.ac.uk/managementschool/research/working%20papers/wp201143.pdf) and distinct occupational practices (Roderick, M. (2006). The work of professional football. A labour of love? London: Routledge). A total of 168 elite youth footballers from the English professional football leagues completed the Athletic Identity Measurement Scale (AIMS). Multilevel modelling was used to examine the effect of playing level, living arrangements and year of apprentice on the total AIMS score and its subscales (i.e., social identity, exclusivity and negative affectivity). Football club explained 30% of the variance in exclusivity among players (P = .022). Mean social identity was significantly higher for those players in the first year of their apprenticeship compared to the second year (P = .025). All other effects were not statistically significant (P > .05). The novel and unique findings have practical implications in the design and implementation of career support strategies with respect to social identity. This may facilitate the maintenance of motivation over a 2-year apprenticeship and positively impact on performance levels within the professional football environment.  相似文献

Abstract

The aim of this study was to examine the effects of changes in maximal aerobic (MAS) and sprinting (MSS) speeds and the anaerobic reserve (ASR) on repeated-sprint performance. Two hundred and seventy highly-trained soccer players (14.5 ± 1.6 year) completed three times per season (over 5 years) a maximal incremental running test to approach MAS, a 40-m sprint with 10-m splits to assess MSS and a repeated-sprint test (10 × 30-m sprints), where best (RSb) and mean (RSm) sprint times, and percentage of speed decrement (%Dec) were calculated. ASR was calculated as MSS-MAS. While ?RSb were related to ?MSS and ?body mass (r2 = 0.42, 90%CL[0.34;0.49] for the overall multiple regression, n = 334), ?RSm was also correlated with ?MAS and ?sum of 7 skinfolds (r2 = 0.43 [0.35;0.50], n = 334). There was a small and positive association between ?%Dec and ?MAS (r2 = 0.02 [?0.07;0.11], n = 334). Substantial ?MSS and ?MAS had a predictive value of 70 and 55% for ?RSm, respectively. Finally, ?ASR per se was not predictive of ?RSm (Cohen’s = +0.8 to ?0.3 with increased ASR), but the greater magnitude of ?RSm improvement was observed when MSS, MAS and ASR increased together (0.8 vs. +0.4 with ASR increased vs. not, additionally to MSS and MAS). Low-cost field tests aimed at assessing maximal sprinting and aerobic speeds can be used to monitor ?RS performance.  相似文献

The Dearing Report reflects the perspectives on higher education of the Government that appointed it, perspectives that are widely shared among the leaders of British institutions outside of academic life. It is of interest for that, rather than for its recommendations, which are fundamentally flawed. The Report does not show an intimate knowledge of the institutions about which it advises; it separates its discussions of finance from its comments on teaching and learning; it ignores the wide diversity of higher education institutions, subjects, and students in making its sweeping recommendations, and it does not recognise the limits of its own knowledge, nor make provision for the continuing improvement of the knowledge and understanding on which future policies for British higher education might be based. For these and other reasons, the Report is now one of the many problems facing British higher education rather than part of their solution.  相似文献

The education of children with behavioural difficulties is under scrutiny from various quarters. The provision of specialised school environments isbeing questioned and, at the same time, there is pressure to minimise the exclusion of disruptive pupils. The study reported in this article lookedat a group of children whose behaviour had prompted placement in a school for emotionally and behaviourally disordered (EBD) pupils. The results showed the overall rate of psychiatric disturbance in the group was 86% and, in particular, that the rate of Attention Deficit Hyperactivity Disorder (ADHD) was 70%. These findings suggest that a significant minority of disruptive pupils may have their difficulties compounded by the presence of ADHD, and raises the question of whether specific screening processes should be established for such pupils.  相似文献
