Striking a Balance: Stakeholder Perceptions of Risk in Horse Racing
Equine Veterinary Journal, EarlyView.ABSTRACT Background Thoroughbred racing is a major industry, and in recent years, public concerns about equine safety have become more prominent, particularly in relation to on‐track injuries and fatalities. This has challenged the industry's social licence to operate (SLO).

Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

Shuitu Baochi Xuebao, 2017 森林更新或改造是林地极易发生水土流失的关键时期。通过对四川省宜宾市高县马尾松低效林不同改造模式的5个人工径流小区不同降雨量条件下产流产沙数据分析，探索改造初期（3 a）降雨与产流、产沙特征的关系及随植被恢复的演变规律。结果表明：2014年Ⅰ～Ⅴ号径流小区因不同降雨量条件下导致的产流总量较2012年同期分别降低－6.44%，－10.51%，20.95%，13.28%，12.73%；产沙总量降低58.4%，56.38%，77.72%，78.16%，79.68%。产流量与产沙量随降雨量增加呈指数增长趋势 ...

Identification of Rice Dwarf Mutant and Fine Mapping of mhd1 Gene [PDF]
, 2016 株高是水稻株型重要的组成因子，直接关系到水稻的产量，株高过高易引起植株倒伏导致减产，适当矮化则可以达到抗倒、增产的目的。虽然目前已经鉴定不少与水稻矮秆相关的基因，但是能够在生产上实际应用的矮秆主基因仍以sd1为主。因此，寻找和创造能在生产上利用的矮秆种质资源以及研究矮化相关机制具有重要的理论和实践意义。 本研究的材料源于籼稻品种闽恢3301经EMS诱变产生的小粒矮秆突变体，暂命名为mhd1（Minhui3301dwarf1）。mhd1表现出多个异常表型，包括植株矮化、叶片直立变宽、叶色深绿、穗和谷粒较小，

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, EarlyView.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Study on high density cultivation of red microalgae Porphyridium purpureum for Arachidonic acid production [PDF]
, 2016 非可再生化石资源的大量消耗导致了严重的环境问题和气候问题，这使得可再生且碳中性的生物质资源日益受到人们的关注。生物质可作为一种再生资源，在替代化石资源获取燃料、化学品和材料等领域具有广阔前景。其中，微藻具有将废弃物转化成生物燃料、食品、饲料原料以及其他高附加值生化产品的巨大潜能。海洋食物链中，微藻可作为多不饱和脂肪酸（PUFAs）的初级生产者，其种类繁多、含量丰富，具有诸多优点并且富产多种高附加值的生物活性物质。特别是近年来微藻已成为人们获取花生四烯酸（Arachidonicacid，ARA ...

Narrative power in the narrative policy framework
Policy Studies Journal, EarlyView.Abstract The Narrative Policy Framework lacks clear and empirical explanations of power. Yet, the study of narratives is inherently the study of power in shaping policy outputs and decisions. We develop a conceptual model positing that expressions of power (power to, with, and over) may be discovered in narrative constructs (e.g., narrative structure ...
