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).

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 ...

Shuitu Baochi Xuebao, 2011 研究露地蔬菜覆膜垄沟种植体系中2种不同的种植方式(膜上、膜侧)对滇池面山台梯地农田表层土壤结构稳定性及农田产流的影响。结果表明:与膜上种植方式比较,膜侧种植方式对种植行0-5cm土层的容重、孔隙分布及>0.25mm水稳性团聚体含量均无明显影响。在5-10cm土层,虽然膜侧种植方式下的总孔隙度及>60μm孔隙度显著低于膜上种植方式的,但是2种种植方式下5-10cm土层>0.25mm水稳性团聚体含量间的差异不显著。这表明膜侧种植方式不会明显降低表层土壤的结构稳定性。与膜上种植方式比较 ...

, 2007 应用非饱和土壤水运动理论,建立膜下滴灌条件下土壤水分运动二维数值模拟模型,研究了田间层状土壤在膜下滴灌条件下土壤水分运动特征。应用不同小区不同灌水处理的实测值与模拟值进行对比,同时对模型做了精度分析,结果表明符合精度要求,这说明所建立的模型能客观地反映实际土壤条件下的水分运动情况。研究结果表明:土壤剖面30~40 cm粘土层使土壤水分运动具有很大的差异,0~30 cm变化明显,而40 cm以下土壤水分运动的变化较小。膜下滴灌应该采取灌水量小 ...

Continuities in policy change: The case of squatter housing redevelopment strategies in Türkiye
Review of Policy Research, Volume 43, Issue 1, January 2026.Abstract The introduction of the neoliberal agenda in the 1980s marked a milestone for urban studies, where the neoliberal framework became widely accepted as both given and explanatory for understanding urban phenomena. This tendency often obscured policy continuities rooted in the historical and social contexts of specific geographies.

, 2015 悠久的茶史积淀了武夷茶种植的文化内核,这尤其体现在以下几个方面:首先,碧水丹山与茶树的牵手造就了源远流长、博大精深的武夷茶文化。第二,因为万里茶路始自武夷山下梅村,武夷山茶作为起点之茶被赋予至高品质、神圣光环和至尊地位。同时,万里茶路的兴起促进了武夷茶种植规模的扩大。第三,因为武夷茶的卓越名声,因为万里茶路、丝绸之路等贸易方式的影响,也因为饮茶习俗在异域的普及和盛行,武夷茶开始了向全世界跨境种植的征程,成为世界茶文化传播的重要祖源。第四,武夷茶种植与儒释道文化互动密切,这又昭示了武夷茶文化发展的种种可能。
