Fishing tournaments are a common feature in recreational angling across a wide range of target species in both fresh and salt waters. Tournaments are organised for a number of purposes, including as commercial enterprises; as fund-raising initiatives for angling clubs; for economic development purposes (e.g. tourism); as well as improve participants' skill levels. Most tournaments are confined to geographically small areas and usually occur over a small number of days, which can mean a pulse of economically significant activity in the local area. This paper analyses the nature of expenditure associated with angling tournaments, including travel, food and accommodation, and angling-related expenditures as a function of socio-economic and angler characteristics. Analysis based on 106 tournaments across Ireland during 2013 finds a clear 80/20 segmentation between ‘high’- and ‘low’-spend anglers and that the segmentation occurs across all fish target species considered. The analysis also finds that British coarse anglers participating at Irish angling tournaments spend considerably more than other anglers irrespective of target species or angler country of origin. 相似文献

The charity/tragedy discourse of disability and traditional versions of femininity bear some striking resemblances. Both are associated with dependence and helplessness, and with resultant practices that are implicated in the enduring reproduction of social and material inequalities. This article looks at the 'identity work' of a group of girls, all of whom had been identified as having 'special educational needs', in a mainstream school in the UK. Using findings from an ethnographic study, the article explores how the girls position themselves in relation to the subject 'special needs student'. The findings suggest that historical meanings associated with femininity and disability combine with contemporary schooling practices to produce a constrained range of subject positions around which the girls have limited room for manoeuvre. 相似文献

Decades of communication research have demonstrated that political candidate images are important predictors of electoral success and that campaign communication influences these image perceptions. However, questions remain about the relative importance of various facets of candidate image, how electoral context and partisanship influence the salience of these facets, and whether privileged classes enjoy presumption in image facets that reinforce their dominant position in politics. These questions require a new approach to image research. We propose a multifactor approach that explores the relative importance of six image traits: character, intelligence, leadership, benevolence, homophily, and charm. The benefits of this approach are illustrated through application to two electoral contexts, the 2012 U.S. presidential election and the 2014 U.S. midterm elections. 相似文献

Perception of effort, also known as perceived exertion or sense of effort, can be described as a cognitive feeling of work associated with voluntary actions. The aim of the present review is to provide an overview of what is perception of effort in Exercise Science. Due to the addition of sensations other than effort in its definition, the neurophysiology of perceived exertion remains poorly understood. As humans have the ability to dissociate effort from other sensations related to physical exercise, the need to use a narrower definition is emphasised. Consequently, a definition and some brief guidelines for its measurement are provided. Finally, an overview of the models present in the literature aiming to explain its neurophysiology, and some perspectives for future research are offered. 相似文献

Managing cognitive load in educational multi-user virtual environments: reflection on design practice 总被引:1,自引:0,他引:1

In this paper, we explore how the application of multimedia design principles may inform the development of educational multi-user virtual environments (MUVEs). We look at design principles that have been shown to help learners manage cognitive load within multimedia environments and conduct a conjectural analysis of the extent to which such principles can help manage cognitive load in the highly immersive “beyond multimedia” environments that 3-D educational MUVEs represent. We frame our discussion as a design practice analysis of the River City MUVE, a science inquiry environment that has middle school students collaborating to develop and test hypotheses regarding illnesses sweeping a virtual town. We analyze the current River City interface design using a framework describing cognitive overload scenarios and associated approaches to manage cognitive load. We also discuss the potential difficulties that may be seen as multimedia principles are applied to 3-D MUVEs. Our discussion describes a blueprint for research implementations that we are undertaking to systematically investigate the effect of an educational MUVE interface design based on multimedia principles—implementations that we hope will provide an action framework for other MUVE researchers to use in their own studies. 相似文献

Purpose:This systematic review and meta-analysis aimed to evaluate the effect of wearable devices for improving physical activity and healthrelated outcomes in cancer survivors.Methods:CINAHL,Cochrane,Ebscohost,MEDLINE,Pubmed,ProQuest Health and Medical Complete,ProQuest Nursing and Allied Health Source,ScienceDirect,and SPORTDiscus databases were searched for randomized controlled trials published before September 1,2020,that evaluated interventions involving wearable devices in cancer survivors.Standardized mean differences(SMDs)were calculated to assess effects on physical activity and health-related outcomes.Subgroup analyses were conducted to assess whether the effects differed by interventions and cancer characteristics.Risk of bias was assessed using the Cochrane risk of bias tool.Results:Thirty-five trials were included(breast cancer,n=15,43%).Intervention durations ranged between 4 weeks and 1 year.Most trials(n=25,71%)involved pedometer-based physical activity interventions.Seven(20%)involved Fitbit-based interventions,and 3(9%)involved other wearable physical activity trackers(e.g.,Polar,Garmin).Compared to usual care,wearable devices had moderate-to-large effects(SMD range 0.54-0.87,p<0.001)on moderate-intensity physical activity,moderate-to-vigorous-intensity physical activity,total physical activity,and daily steps.Compared to usual care,those in the intervention had higher quality of life,aerobic fitness,physical function,and reduced fatigue(SMD range=0.18-0.66,all p<0.05).Conclusion:Wearable physical activity trackers and pedometers are effective tools that increase physical activity and improve health-related outcomes in individuals with cancer.Identifying how these devices can be implemented for longer-term use with other intervention components remains an area for future research. 相似文献
