Measuring spoken language: a unit for all reasons

Abstract: The analysis of spoken language requires a principled way of dividing transcribed data into units in order to assess features such as accuracy and complexity. If such analyses are to be comparable across different studies, there must be agreement on the nature of the unit, and it must be possible to apply this unit reliably to a range of different types of speech data. There are a number of different units in use, the various merits of which have been discussed by Crookes (1990). However, while these have been used to facilitate the analysis of spoken language data, there is presently no comprehensive, accessible definition of any of them, nor are detailed guides available on how to identify such units in data sets. Research reports tend to provide simplistic two-line definitions of units exemplified, if at all, by unproblematic written examples. These are inadequate when applied to transcriptions of complex oral data, which tend not to lend themselves easily to a clear division into units. This paper was motivated by the need each of the three authors felt for a reliable and comprehensively defined unit to assist with the analysis of a variety of recordings of native and non-native speakers of English. We first discuss in very general terms the criteria according to which such a unit might be selected. Next, we examine the main categories of unit which have been adopted previously and provide a justification for the particular type of unit that we have chosen. Focusing on this unit, we identify a number of problems which are associated with the definition and exemplification of units of this type, and give examples of the awkward cases found in actual data. Finally we offer a definition of our unit, the Analysis of Speech Unit (AS-unit), providing adequate detail to address the problematic data analyses we have illustrated.

The prevention and treatment of exercise-induced muscle damage.

Abstract: Exercise-induced muscle damage (EIMD) can be caused by novel or unaccustomed exercise and results in a temporary decrease in muscle force production, a rise in passive tension, increased muscle soreness and swelling, and an increase in intramuscular proteins in blood. Consequently, EIMD can have a profound effect on the ability to perform subsequent bouts of exercise and therefore adhere to an exercise training programme. A variety of interventions have been used prophylactically and/or therapeutically in an attempt to reduce the negative effects associated with EIMD. This article focuses on some of the most commonly used strategies, including nutritional and pharmacological strategies, electrical and manual therapies and exercise. Long-term supplementation with antioxidants or β-hydroxy-β-methylbutyrate appears to provide a prophylactic effect in reducing EIMD, as does the ingestion of protein before and following exercise. Although the administration of high-dose NSAIDs may reduce EIMD and muscle soreness, it also attenuates the adaptive processes and should therefore not be prescribed for long-term treatment of EIMD. Whilst there is some evidence that stretching and massage may reduce muscle soreness, there is little evidence indicating any performance benefits. Electrical therapies and cryotherapy offer limited effect in the treatment of EIMD; however, inconsistencies in the dose and frequency of these and other interventions may account for the lack of consensus regarding their efficacy. Both as a cause and a consequence of this, there are very few evidence-based guidelines for the application of many of these interventions. Conversely, there is unequivocal evidence that prior bouts of eccentric exercise provide a protective effect against subsequent bouts of potentially damaging exercise. Further research is warranted to elucidate the most appropriate dose and frequency of interventions to attenuate EIMD and if these interventions attenuate the adaptation process. This will both clarify the efficacy of such strategies and provide guidelines for evidence-based practice.

Task Design and Second Language Performance: The Effect of Narrative Type on Learner Output

Abstract: This article presents a study examining how narrative structure and narrative complexity might influence the performance of second language learners. Forty learners of English in London and sixty learners in Teheran were asked to retell cartoon stories from picture prompts. Each performed two of four narrative tasks that had different degrees of narrative structure (loose or tight) and of storyline complexity (with or without background events). Results support the findings of previous research that tight task structure is connected to increased accuracy and that narratives involving background information give rise to more complex syntax. A comparison of the data from the London and Teheran cohorts showed that the learners in London used significantly more complex syntax and diverse vocabulary even though they did not differ from the Teheran learners in other performance dimensions.

Sleep duration and quality in elite athletes measured using wristwatch actigraphy

Abstract: Sleep is known to be an important component of recovery from training, yet little is known about the quality and quantity of sleep achieved by elite athletes. The aim of the present study was to quantify sleep in elite athletes using wristwatch actigraphy. Individual nights of sleep from a cohort of Olympic athletes (n = 47) from various sports were analysed and compared to non-athletic controls (n = 20). There were significant differences between athletes and controls in all measures apart from ‘time asleep’ (p = 0.27), suggesting poorer characteristics of sleep in the athlete group. There was a significant effect of gender on ‘time awake’ (mean difference: 12 minutes higher in males; 95% likely range: 3 to 21 minutes) and ‘sleep efficiency’ (mean difference: 2.4 lower in males; 95% likely range: 0.1 to 4.8). Athletes showed poorer markers of sleep quality than an age and sex matched non-athletic control group (Sleep efficiency: 80.6 ± 6.4% and 88.7 ± 3.6%, respectively. Fragmentation Index: 36....

The Reliability and Validity of Fatigue Measures During Multiple-Sprint Work: An Issue Revisited

Abstract: The ability to repeatedly produce a high-power output or sprint speed is a key fitness component of most field and court sports. The aim of this study was to evaluate the validity and reliability of eight different approaches to quantify this parameter in tests of multiple-sprint performance. Ten physically active men completed two trials of each of two multiple-sprint running protocols with contrasting recovery periods. Protocol 1 consisted of 12 × 30-m sprints repeated every 35 seconds; protocol 2 consisted of 12 × 30-m sprints repeated every 65 seconds. All testing was performed in an indoor sports facility, and sprint times were recorded using twin-beam photocells. All but one of the formulae showed good construct validity, as evidenced by similar within-protocol fatigue scores. However, the assumptions on which many of the formulae were based, combined with poor or inconsistent test-retest reliability (coefficient of variation range: 0.8-145.7%; intraclass correlation coefficient range: 0.09-0.75), suggested many problems regarding logical validity. In line with previous research, the results support the percentage decrement calculation as the most valid and reliable method of quantifying fatigue in tests of multiple-sprint performance.
