Rethinking participation in the Aarhus as European Capital of Culture 2017 project     

Leila Jancovich  Louise Ejgod Hansen 《Cultural Trends》2018,27(3):173-186

This paper examines the relationship between cultural participation and regional development with reference to the European Capital of Culture in 2017. From the bidding stage, Aarhus 2017 claimed it put “participation” at the heart of its strategic plans, through consultation at roadshows and exhibitions. In addition, it aspired to use culture as a catalyst for development not only in the city of Aarhus but across the region of Central Denmark. This paper, therefore, examines how participation is defined and implemented to address regional development in the Aarhus 2017 process through textual analysis of documentation from Aarhus 2017 and delivery partners as well as over 20 interviews with managers and participants involved in a range of 2017 projects. The paper argues against the common prioritisation of urban and professional cultural institutions and makes the case for decentralised cultural provision that supports both amateurs and professionals through a regional networked structure.  相似文献   

The effect of beetroot juice supplementation on repeat-sprint performance in hypoxia     

Georgina L. Kent  Brian Dawson  Lars R. McNaughton  Gregory R. Cox  Louise M. Burke  Peter Peeling 《Journal of sports sciences》2019,37(3):339-346

This investigation assessed the effect of dietary nitrate (NO₃^?) supplementation, in the form of beetroot juice (BR), on repeat-sprint performance in normoxia and normobaric hypoxia. 12 male team-sport athletes (age 22.3 ± 2.6 y, VO_2peak 53.1 ± 8.7 mL.kg^?1.min^?1) completed three exercise trials involving a 10 min submaximal warm-up and 4 sets of cycling repeat-sprint efforts (RSE; 9 × 4 s) at sea level (CON), or at 3000 m simulated altitude following acute supplementation (140 mL) with BR (HYP_BR; 13 mmol NO₃^?) or NO₃^–depleted BR placebo (HYP_PLA). Peak (PPO) and mean (MPO) power output, plus work decrement were recorded during the RSE task, while oxygen consumption (VO₂) was measured during the warm-up. There were no significant differences observed between HYP_BR and HYP_PLA for PPO or MPO; however, work decrement was reduced in the first RSE set in HYP_BR compared with HYP_PLA. There was a moderate effect for VO₂ to be lower following BR at the end of the 10 min warm-up (ES = 0.50 ± 0.51). Dietary NO₃^? may not improve repeat-sprint performance in hypoxia but may reduce VO₂ during submaximal exercise. Therefore, BR supplementation may be more effective for performance improvement during predominantly aerobic exercise.  相似文献   

Carnosine in health and disease     

Guilherme Giannini Artioli  Craig Sale  Rebecca Louise Jones 《European Journal of Sport Science》2019,19(1):30-39

Abstract

Carnosine was originally discovered in skeletal muscle, where it exists in larger amounts than in other tissues. The majority of research into the physiological roles of carnosine have been conducted on skeletal muscle. Given this and the potential for muscle carnosine content to be increased with supplementation, there is now a large body of research examining the ergogenic effects (or otherwise) of carnosine. More recent research, however, points towards a potential for carnosine to exert a wider range of physiological effects in other tissues, including the brain, heart, pancreas, kidney and cancer cells. Taken together, this is suggestive of a potential for carnosine to have therapeutic benefits in health and disease, although this is by no means without complication. Herein, we will provide a review of the current literature relating to the potential therapeutic effects of carnosine in health and disease.  相似文献   

Exploring askers’ switching from free to paid social Q&A services: A perspective on the push-pull-mooring framework     

Zhouying Liu  Yuxiang Zhao  Si Chen  Shijie Song  Preben Hansen  Qinghua Zhu 《Information processing & management》2021,58(1):102396

The purpose of this study is to explore the factors that prompt askers to switch from free to paid social question-and-answer (SQA) services. Prior studies have investigated users’ motivations and participation in free and paid SQA services; however, little attention has been paid to askers’ switching behavior. We empirically analyzed the content of qualitative interviews from 64 askers on a well-known SQA platform in China. Based on the push-pull-mooring framework, we identified and classified factors that influenced askers’ to switch from free to paid Q&A services, using the critical incident technique, after which we calculated the entropy weights of the 16 subcategories before and after the switch, using the entropy weight method. The findings suggest that askers’ switching behavior was influenced by push factors (i.e., dissatisfaction with the free SQA service), pull factors (i.e., satisfaction with the paid SQA service), and mooring factors (i.e., social factors, personal factors, situational factors). Moreover, the findings show that the effects of these factors vary significantly before and after a switch. Dissatisfaction with the quality of information from the free SQA service would influence users before a switch, whereas satisfaction with the quality of information from the paid SQA service would influence them after a switch. In terms of mooring factors, the effects of social and personal factors on askers’ switching behavior, especially subjective norms and cognitive lock-in, turn out to be less significant after a switch, whereas the effect of trust is more significant. Besides, the effects of situational factors are more or less the same before and after a switch. To the best of our knowledge, this paper is one of the first attempts to explore factors that affect askers’ switching behavior and to shed light on the managerial strategies of paid SQA services.  相似文献   

Children’s Reading Comprehension and Oral Reading Fluency in Easy Text     

Louise Spear-Swerling 《Reading and writing》2006,19(2):199-220

This study explored third-graders’ oral reading fluency (ORF) in easy text in relation to their third- and fourth-grade reading comprehension. It also examined the children’s performance on two different measures of text exposure, a self-report questionnaire and a title-recognition test. Although third-graders’ ORF related significantly to their reading comprehension, oral language comprehension accounted for most of the variance in reading comprehension, whereas single word reading speed accounted for most of the variance in ORF. Third-grade reading comprehension and ORF each predicted unique variance in children’s scores on a fourth-grade state-mandated reading comprehension assessment. Scores on the self-report questionnaire correlated significantly with third-grade ORF and fourth-grade reading; the self-report accounted for reliable variance in ORF even with all of the other reading ability variables entered first. Results are consistent with the viewpoint that text exposure affects reading fluency. They also demonstrate that ORF is a valuable predictor of middle-elementary children’s reading comprehension, even when the ORF measure employs very easy text in which children achieve near-perfect word accuracy.  相似文献   

Decision-oriented frameworks for management information systems design     

James V. Hansen  Lynn J. McKell  Lester E. Heitger 《Information processing & management》1977,13(4):215-225

Despite the rapid growth in the use of computers in organizations, few of the resulting systems have had a significant impact on the way in which management makes decisions. Frameworks are needed which aid in understanding the structure of management information systems, toward providing focus and improving the effectiveness of systems efforts.This paper surveys recent conceptual and empirical work related to development of decision-oriented frameworks for management information systems design, particularly as related to the improving the management of organizations.  相似文献   

What’s in a name? Preschoolers’ noun learning performance in relation to their risk for reading disability     

Megan Louise Gilliver  Brian Byrne 《Reading and writing》2009,22(6):637-659

This paper reports the findings of an investigation aimed at gaining a clearer understanding of the nature of vocabulary difficulties associated with dyslexia and associated risk status. Three studies were conducted to examine preschoolers’ access and mastery of syntactic- and phonological-based processes believed to support word learning. Results are reported for 82 participants whose (reading) risk status was assessed from a composite of measures known to be related to reading development. As expected, risk status correlated positively with participants’ ability to recall the phonological form of novel nouns. No relationship was found between risk status and participants’ use of syntactic form-class cues in interpreting the noun class of novel names in isolation. However, the ability to use form-class cues was impaired for at-risk participants on a task that required them to learn both the phonological form and noun class. Findings are discussed in relation to the suggestion that limitations in processing resources such as working memory rather than in the availability of language structures may be at the root of the reported poor performance by at-risk children on vocabulary and other linguistic measures.

Thinking about the future because of the past: young children's knowledge about the causes of worry and preventative decisions     

Lagattuta KH 《Child development》2007,78(5):1492-1509

Two studies investigated 3- to 6-year-olds' and adults' (N= 128) knowledge about emotions and behaviors caused by thinking about the future because of the past. Participants listened to stories featuring characters that experienced negative events, and then, many days later, felt worried or changed their behaviors upon seeing an entity associated with the prior harm. Results revealed a significant increase between 3 and 5 years in the frequency that participants explained characters' reactions as caused by anticipating the reoccurrence of a negative past event. Across age, females more often marked future events as uncertain, as well as predicted that people in ambiguous risk situations would feel worried due to past-to-future connections.  相似文献   

Physical activity patterns of ethnic children from low socio-economic environments within the UK     

Emma Lisa Jane Eyre  Michael Joseph Duncan  Samantha Louise Birch  Valerie Cox  Matthew Blackett 《Journal of sports sciences》2015,33(3):232-242

Many children fail to meet physical activity (PA) guidelines for health benefits. PA behaviours are complex and depend on numerous interrelated factors. The study aims to develop current understanding of how children from low Socio-economic environments within the UK use their surrounding built environments for PA by using advanced technology. The environment was assessed in 96 school children (7–9 years) using global positioning system (GPS) monitoring (Garmin Forerunner, 305). In a subsample of 46 children, the environment and PA were assessed using an integrated GPS and heart rate monitor. The percentage of time spent indoor, outdoor, in green and non-green environments along with time spent in moderate-to-vigorous PA (MVPA) in indoor and outdoor environments were assessed. A 2-by-2 repeated measures analysis of covariance, controlling for body mass index, BF%, assessed the environmental differences. The findings show that 42% of children from deprived wards of Coventry fail to meet PA guidelines, of which 43% was accumulated during school. Children engaged in more MVPA outdoor than indoor environments (P < 0.01) and a greater amount of time was spent in non-green environments (P < 0.01). Increased time outdoors was negatively associated with BF%. In conclusion, outdoor environments are important for health-enhancing PA and reducing fatness in deprived and ethnic children.  相似文献   

Assessment is learning: the preposition vanishes     

Louise Hayward 《Assessment in Education: Principles, Policy & Practice》2015,22(1):27-43

Scotland, in common with many countries internationally, has been learning how to align ideas from research with policy and practice. This article considers what Scotland learned from large-scale evaluations of its Assessment is for Learning (AifL) programme and the extent to which this evidence was used to inform future learning within the national programme. More recently, the policy focus in Scotland has shifted to the creation of a new curriculum, Curriculum for Excellence, subsuming AifL. Merging curriculum and assessment innovations brought new challenges in the alignment of curriculum, pedagogy and assessment. Drawing on a Scottish Government-funded research project, Assessment at Transition, designed to identify and explore emerging gaps between practice in schools and local authorities and national curriculum and assessment policy aspirations, the article argues that assessment is learning and explores how formative approaches to evaluation at a national level might be used to prevent countries repeating past mistakes.  相似文献
