Tudor-Locke and colleagues previously assessed steps/day for 1 year. The aim of this study was to use this data set to introduce a novel approach for the investigation of whether individual’s physical activity exhibits periodicity fluctuating round a mean and, if so, the degree of fluctuation and whether the mean changes over time. Twenty-three participants wore a pedometer for 365 days, recorded steps/day and whether the day was a workday. Fourier transform of each participant’s daily steps data showed the physical activity had a periodicity of 7 days in half of the participants, matching the periodicity of the workday pattern. Activity level remained stable in half of the participants, decreased in ten participants and increased in two. In conclusion, the 7-day periodicity of activity in half of the participants and correspondence with the workday pattern suggest a social or environmental influence. The novel analytical approach introduced herein allows the determination of the periodicity of activity, the degree of variability in activity that is tolerated during day-to-day life and whether the activity level is stable. Results from the use of these methodologies in larger data sets may enable a more focused approach to the design of interventions that aim to increase activity.  相似文献

Playing with tension: national charisma and disgrace at Euro 2012     

Alex Law 《Soccer & Society》2014,15(2):203-221

By the time of Euro 2012, deepening tensions of nationalism and internal social struggles were developing across Europe in worsening conditions of systemic crisis. The official football ideology of UEFA conceives Euro 2012 as a civilizing platform for mutual respect and brotherhood between competing nations. In contrast, what I call Hyper-Critical Theory conceives of football competitions like Euro 2012 as part of a de-civilising ‘sports mode of production’ that necessarily produces crisis conditions, alienation and violence on a mass scale, fostering nationalism, militarism and racism. Between these polar perspectives, the figurational sociology of sport associated with Norbert Elias proposes that major international football competitions like Euro 2012 creates and dissipates contingent tensions of ‘group charisma’ and ‘group disgrace’. Study of Euronews ‘post-national’ coverage of Euro 2012 allows their explanatory adequacy to be compared. In a competition structure like the Euros no social group – players, officials, media or fans – is able to disregard entirely the field capabilities of the ‘best minority of 11’ in the serious game of exemplifying the group charisma of nations.  相似文献   

The “Other” in the Crusading Period: Walter the Chancellor's Presentation of Najm al-Dīn Il-Ghāzī     

Alex Mallett 《Al-Masaq: Islam & the Medieval Mediterranean》2010,22(2):113-128

This paper examines ideas surrounding the presentation of the Muslim “other” in Latin writings of the early period of the Crusades. Using a case-study approach of the views of one chronicler, Walter the Chancellor, in his work Bella Antiochena, on one individual Muslim, Najm al-Dīn Il-Ghāzī, the paper studies aspects of the image of Il-Ghāzī, the reasons for them, how and why they develop throughout the chronicle, and whether, from the other information given in the chronicle, it would be possible to interpret the information in other ways. The conclusions reached demonstrate that the reason for the vitriol in Walter's presentation was his wish to justify the Crusades and suggest that the writers of Outremer started to develop their own cross-cultural responses to Islam, independent of mainstream European thought, because of their situation.  相似文献   

A coactive sign system for children who are dual-sensory impaired.     

S Watkins  T C Clark 《American annals of the deaf》1991,136(4):321-324

The SKI*HI Institute developed a system of coactive signing to help alleviate communication and instructional barriers for children who are dual-sensory impaired (deaf and blind). The system also can be used to help children who are severely multihandicapped learn how to communicate. The system includes optimized coactive signs that are functional, easy to feel, easy to relate to the referent, and easy to make, and it also includes techniques related to effective coactive sign use. The coactive sign system is illustrated on a series of video tapes that has been field tested and produced and is being disseminated throughout the United States and Canada.  相似文献   

Thanks,but no-thanks for the feedback     

Alex Forsythe  Sophie Johnson 《Assessment & Evaluation in Higher Education》2017,42(6):850-859

Feedback is an emotional business in which personal disposition influences what is attended to, encoded, consolidated and eventually retrieved. Here, we examine the extent to which students’ perceptions of feedback and their personal dispositions can be used to predict whether they appreciate, engage with and act on the feedback that they receive. The study is framed in psychological theories of mindset, defensive behaviours and new psychometric measures of the psychological integration of assessment feedback. Results suggest that, in this university population, growth mindset students were in the minority. Generally, students are fostering self-defensive behaviours that fail to nurture remediation following feedback. Recommendations explore the implications for students who engage in self-deception, and the ways in which psychologists and academics may intercede to help students progress academically by increasing their self-awareness.  相似文献
