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.

The preparation and basic researches of blood vessels with anticoagulant and endothelial functions [PDF]
, 2017 小口径血管一般是指直径小于6mm的血管，人工血管移植物已经被大量地应用于临床实践中，目前临床上常用的主要有自体血管移植物、异体血管移植物和人工合成的高分子材料血管移植物等3大类血管移植物。其中前两类由于来源有限与异体排斥反应局限了其临床应用，而高分子合成材料制成的人工血管已在大口径血管移植方面取得了比较大的进展，但在小口径血管移植方面一直没有取得突破性进展，究其原因主要还是由于血管材料的内皮化功能欠缺，机械性能不如天然血管等，故本文采取将细胞种植于人工材料表面的方法，制备人源性细胞外基质 ...

Integrative Conservation, Volume 4, Issue 4, Page 686-694, December 2025.The soil fungicide reduces the occurrence of pathogenic fungi in invaded soil and at the same time promotes the recruitment of mycorrhizal fungi and saprophytic fungi by the plants. The addition of biochar to the invaded soil has a negative legacy effect on subsequent invasive plants, while it exerts a positive enhancement effect on native plants ...

People and Nature, Volume 7, Issue 11, Page 2700-2713, November 2025.Abstract Large old trees are important ecological entities in human settlements, providing cultural values and ecological services that are threatened by current and future changes in global climate, land use and disturbance regimes. Some studies suggest incorporating social and cultural significance into the conservation of large old trees.

Functional Ecology, Volume 39, Issue 10, Page 2889-2904, October 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract In the Southwest Australian Biodiversity Hotspot, the greatest plant species diversity tends to occur on the most phosphorus (P)‐impoverished soils. Many plant species in this P‐impoverished environment release root carboxylates that mobilise soil P which is a more ...
