Business Strategy and the Environment, EarlyView.ABSTRACT Green claims pervade corporate communications, yet their informational value varies because stakeholders process them under bounded rationality—scarce attention and costly verification. This paper develops a conceptual signalling framework in which three parameters—signal diagnosticity (D), verification frictions (V) and available attention (A)

四川大学学报. 自然科学版, 2005 适量的钒掺杂,大大增加了SrBi4Ti4O15(SBTi)铁电材料的剩余极化2Pr,并改善了材料的耐压性能.SBTi拉曼模的位置,基本不受V掺杂的影响,但对应Ti O6氧八面体的拉曼模在掺杂明显宽化,这与V5+取代进入Ti O6中的Ti4+后,材料局部无序性增大,应力增加有关.X射线光电子能谱表明,不同掺杂量样品的Bi4f和Ti2p的结合能未有明显变化,这与B位高价掺杂减少氧空位的特殊机制有关.材料的2Pr增加,是高价阳离子掺杂导致材料中氧空位浓度的减少,局部无序性的增加共同作用的结果.

Impact of Emission Reduction Targets on Corporate Greenwashing: International Empirical Evidence
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study investigates the influence of emission reduction target characteristics on corporate greenwashing propensity. Through the analysis of 4938 international observations via probit regression, we examine four key dimensions: science‐based validation, target compliance, timeframe, and organizational coverage.

四川大学学报. 自然科学版, 2005 用固相烧结法制备了不同Nd掺杂量的SrBi4-xNdxTi4O15(SBNT-x,x=0.00～1.00)铁电陶瓷.X射线衍射谱显示Nd掺杂未改变SrBi4Ti4O15(SBTi)的晶体结构.铁电测量表明,适量的Nd掺杂使SBTi的剩余极化(2Pr)显著增加.当x=0.18时,2Pr达到极大值,为25.8μC/cm2,和未掺杂相比,增长约56%.样品的矫顽场在x=0.00到0.18之间几乎不变,而在更大掺杂量下,随掺杂量的增加而逐步减小.掺杂引起材料中点缺陷浓度降低和晶格畸变减小 ...
