Content marketing involves creating content in genres that readers find useful. These genres individually do not persuade their readers to buy a given product and may not even mention the product or service being marketed. But collectively, they are designed to lead their readers to a purchase decision, that is, they sell without selling. The authors examine how content marketers strategically deploy these ecologies of genres. 相似文献

Diurnal variation in cycling performance: influence of warm-up 总被引:2,自引:0,他引:2
We examined the effects of time of day on a cycling time trial with and without a prolonged warm-up, among cyclists who tended towards being high in "morningness". Eight male cyclists (mean +/- s: age = 24.9 +/- 3.5 years, peak power output = 319 +/- 34 W, chronotype = 39 +/- 6 units) completed a 16.1-km time trial without a substantial warm-up at both 07:30 and 17:30 h. The time trial was also completed at both times of day after a 25-min warm-up at 60% of peak power. Power output, heart rate, intra-aural temperature and category ratings of perceived exertion (CR-10) were measured throughout the time trial. Post-test blood lactate concentration was also recorded. Warm-up generally improved time trial performance at both times of day (95% CI for improvement = 0 to 30 s), but mean cycling time was still significantly slower at 07:30 h than at 17:30 h after the warm-up (95% CI for difference = 33 to 66 s). Intra-aural temperature increased as the time trial progressed (P < 0.0005) and was significantly higher throughout the time trials at 17:30 h (P = 0.001), irrespective of whether the cyclists performed a warm-up or not. Blood lactate concentration after the time trial was lowest at 07:30 h without a warm-up (P = 0.02). No effects of time of day or warm-up were found for CR-10 or heart rate responses during the time trial. These results suggest that 16.1-km cycling performance is worse in the morning than in the afternoon, even with athletes who tend towards 'morningness', and who perform a vigorous 25-min warm-up. Diurnal variation in cycling performance is, therefore, relatively robust to some external and behavioural factors. 相似文献

The designation of overlapping hierarchies in thesauri, first outlined in 1973, is suggested as a key element in progress towards a successful man-machine partnership. An updating, expansion and theoretical background of the 1973 proposal are given. The use of the UDC, both as a matrix and a searching aid, is postulated but is not essential. Means of distinguishing overlapping terms from other “related terms” are suggested, in order to make possible the accurate representation of all hirarchical relationships. At its largest, the result could be a “Universal Reference Vocabulary”, maintained on-line only and used to construct profiles before searching via natural language and/or class numbers. It is suggested that a computer program package for a small model area within Social Sciences should be given priority. 相似文献
