Utilizing dimensional Analysis with Observed data to determine the Significance of Hydrodynamic Solutions in Coastal Hydrology

引用

Computational Water, Energy, and Environmental Engineering 2014年第2期3卷 57-77页

作者： Eric d. Swain Jeremy d. decker Joseph d. Hughes US Geological Survey Florida Water Science Center Fort Lauderdale USA US Geological Survey Florida Water Science Center Tampa USA

In this paper, the authors present an analysis of the magnitude of the temporal and spatial acceleration (inertial) terms in the surface-water flow equations and determine the conditions under which these inertial terms have sufficient magnitude to be required in the computations. data from two South Florida field sites are examined and the relative magnitudes of temporal acceleration, spatial acceleration, and the gravity and friction terms are compared. Parameters are derived by using dimensionless numbers and applied to quantify the significance of the hydrodynamic effects. The time series of the ratio of the inertial and gravity terms from field sites are presented and compared with both a simplified indicator parameter and a more complex parameter called the Hydrodynamic Significance Number (HSN). Two test-case models were developed by using the SWIFT2d hydrodynamic simulator to examine flow behavior with and without the inertial terms and compute the HSN. The first model represented one of the previously-mentioned field sites during gate operations of a structure-managed coastal canal. The second model was a synthetic test case illustrating the drainage of water down a sloped surface from an initial stage while under constant flow. The analyses indicate that the times of substantial hydrodynamic effects are sporadic but significant. The simplified indicator parameter correlates much better with the hydrodynamic effect magnitude for a constant width channel such as Miami Canal than at the non-uniform North River. Higher HSN values indicate flow situations where the inertial terms are large and need to be taken into account.

Purpose: The aim of this study was to examine whether the efficacy of transtheoretical model(TTM)-based interventions on physical activity(PA)varied according to the following criteria:(1) interventions targeted the actual stages of change(SOCs) or did not;(2) participants were selected according to their SOC or were not; and(3) its theoretical constructs(decisional balance, temptation, self-efficacy, processes of change).Methods: Thirty-three randomized controlled trials assessing TTM-based interventions promoting PA in adults were systematically ***: The between-group heterogeneity statistic(Qb) did not reveal any differential efficacy either in interventions targeting the actual SOC compared with those that did not(Qb = 1.48, p = 0.22) or in interventions selecting participants according to their SOC compared with those that did not(Qb = 0.01, p = 0.91). TTM-based interventions enhanced PA behavior whether they targeted the actual SOC(Cohen's d = 0.36; 95%confidence interval(CI): 0.22–0.49) or not(d = 0.23; 95%CI: 0.09–0.38) and whether they selected their participants according to their SOC(d = 0.33; 95%CI: 0.13–0.53) or not(d = 0.32; 95%CI: 0.19–0.44). The moderators of the efficacy of TTM-based interventions were the number of theoretical constructs used to tailor the intervention(Qb = 8.82, p = 0.003), the use of self-efficacy(Qb = 6.09, p = 0.01), and the processes of change(Qb = 3.51, p = 0.06).Conclusion: TTM-based interventions significantly improved PA behavior, and their efficacy was not moderated by SOC but by the TTM theoretical constructs.

二十世纪90年代末到二十一世纪初,在北京、上海的外国人及美籍华裔将嘻哈文化带入中国,中国大陆出现了第一批说唱歌手。通过嘻哈聚会、说唱音乐电台、自由式说唱比赛等形式的推广,中国大陆的说唱音乐逐渐发展起来。其本土化虽具有真实性,但是在政治场域的约束下进行的。因此在2017年《中国有嘻哈》将嘻哈文化和说唱音乐带入大众视野之前,中国大陆的说唱音乐一直处于地下状态。根据伯明翰学派的研究,嘻哈文化作为一种亚文化,具有抵抗性和风格化。因为这两种属性,嘻哈文化拥有一系列的社会功能,包括对社会结构中的矛盾进行象征性的集体解决、促进一种批判性的思考和表达能力、尝试解决一种“认同危机”、满足“社会相符需要”和“社会差别需要”。因为这些功能,主流支配文化会对其进行遏制、框束和收编,其中资本市场对其进行商品方式的收编,政府、媒体和学术界对其进行意识形态方面的收编。2017年被资本市场裹挟进入大众文化的中国嘻哈文化和说唱音乐正经历了上述过程。根据空间理论,中国地下说唱所面临的问题主要源于生存空间的缺失、“真实”概念的改变,“体验”的丧失。通过对十二位中国说唱歌手的访谈和问卷调查,问题包括对于自身说唱的看法、对于中国说唱行业情况的看法、对于《中国有嘻哈》《中国新说唱》等综艺节目的看法,以及外国说唱音乐对自身说唱的影响等,可以看出中国嘻哈新纪元的出现,让中国地下说唱面临各种情况和挑战:一是新旧两代说唱歌手出现观念差异,地下说唱的传统和精神看似无以为继;二是保持风格与在社会上定义自己的身份存在冲突,地下说唱还没找到一条独立、专业的道路可循。尽管说唱音乐的多元化受到了限制,仍然有一些积极的因素可以促进中国地下说唱未来的发展。
