This article employs autoethnographic reflections to contribute towards debates concerning film-induced tourism by analysing the officially endorsed Doctor Who Experience Walking Tour around filming locations from the BBC series in Cardiff Bay, Wales. Approaching this tour as an example of paratextuality, the article pursues two arguments. First, it reflects upon the attempts used within the tour for encouraging connection between participants and the locations visited from the perspective of immersion. However, noting preceding positions, it is recognized that the tour constructs forms of imaginative immersion. The terms symbolic and cued immersion are subsequently introduced to consider the strategies that the tour employs to position fans and engage them with its frequently quotidian spaces. Second, the article explores the links between the tour’s immersive strategies and its institutional context, arguing that these assist in reinforcing core brand values regarding BBC Worldwide.  相似文献

The purpose of this study was to assess the effect of periodized resistance training on accelerative sprint performance. Sixteen physically active men participated in a randomized controlled study. An experimental group (n = 10) completed an 8-week periodized resistance training intervention, while a control group (n = 6) did not train. Pre- and post-training measures of 20-m straight-line sprint time, including a 10-m split, maximum strength, and explosive strength, were recorded. Flight time, stance time, stride length, and stride frequency were quantified from digitized video recordings of the first three strides of the 20-m sprint. Resistance training resulted in significant increases in maximum strength (parallel back squat: 19%) and explosive strength (6-10%). However, both groups increased 0-10 m sprint times (experimental group = 6%; control group = 3%) while 10-20m times were reduced (experimental group = 7%; control group = 4%), highlighting the mechanical differences between the distinct sprint phases. The change during the 0-10m interval was accompanied by a reduction in stride frequency during the first three strides. Strength coaches should be aware that the potential benefits of increased muscular strength during short sprints are likely to be affected by mechanical specificity and that improvements in sprinting performance may not occur immediately after a period of resistance training.  相似文献

Vocational assessment services increasingly are being provided to handicapped secondary school students as a result of recent federal legislation. This article describes the need for such services and describes a vocationally oriented psychological evaluation completed on a handicapped adolescent by a school psychologist. The relevance of traditionally derived school psychological assessment data in vocational programming, the value of expanding assessment batteries to include vocationally specific assessment techniques, and the writing of vocationally oriented psychological reports are discussed.  相似文献

This study surveyed 362 school psychologists to: (a) identify the percentages of school psychologists who have had some involvement in the practices of vocational assessment, vocational counseling, consultation with vocational education teachers, and vocational program or curriculum development, and (b) identify factors that are associated with such vocational involvement. Results indicated that 30–40% of those school psychologists surveyed reported some involvement in vocational assessment, vocational counseling, and consultation with vocational education teachers, while only 12% indicated involvement with vocational program or curriculum development. Sex, experience, salary, perceived control over role functioning, and involvement in practices other than traditional assessment were found to be associated with increased involvement in vocational activities. Results also indicated that school psychologists who were certified guidance counselors, and who were members of the American Association of Counseling and Development, were more likely to be involved in vocational practices than were school psychologists who were not so certified or affiliated. Results are discussed in terms of their implication for involving greater numbers of school psychologists in vocational practices.  相似文献

Introduction: Many factors may contribute to running-related injury. These include fatigue and footwear, the combination of which has rarely been studied, in particular with reference to barefoot running, recently advocated as a method to reduce injury risk. Methods: Twenty-two runners (12 well-trained and 10 trained) participated in a 10?km fatiguing trial. Knee and ankle joint kinematics and kinetics and electromyography were assessed during overground running in the barefoot and shod condition. This was performed pre- and post-fatigue using a motion capture system and force platforms. Results: Initial loading rate increased in the trained runners when barefoot but not shod. Shod knee stiffness increased in both groups after fatigue, whereas barefoot knee stiffness decreased only in the trained group. A reduction in barefoot bicep femoris pre-activation was found in both groups. During stance, a reduction in vastus lateralis and biceps femoris and an increase in tibialis anterior activity were found over time in both groups and conditions. Trained runners decreased gluteus medius and increased lateral gastrocnemius median frequency for both conditions after fatigue. Conclusion: When fatigued, gait adjustments in habitually shod runners may increase injury risk when running barefoot. Training status may be a risk factor for injury, as less-trained runners experience muscular fatigue changes that may compromise ground reaction force attenuation. Caution is recommended when transitioning to pure barefoot running.  相似文献

This article presents findings of an instrumental case study that examined the perceptions held by African-American parents on the efficacy of schools in meeting the needs of African-American learners in a North Carolina community. A theme of distrust emerged and evidenced the need for teachers, administrators, and teacher educators to reconsider approaches used with African-American parents, particularly where building culturally reciprocal home-school-community relationships is concerned.  相似文献

Time-out procedures often seem to be overused by teachers and tend to emphasize a linear view of problem behavior. Paradoxical strategies appear to provide a change in the dynamics of the teacher-child relationship and are thus a more systemic way of viewing the behavior. Three case studies are presented where the paradoxical strategies have varying degrees of success. The cases are discussed in terms of the critical aspects of the approach, as demonstrated in the case studies.  相似文献
