The Influence of CEO’s Characteristics on Accounting Conservatism：Evidence from Chinese Listed Company [PDF]
, 2016 作为会计核算的重要原则之一，会计稳健性对提高企业会计信息质量及减少企业代理成本的作用不可忽视。董事长不直接管理公司，CFO是CEO意见的执行者，CEO作为公司管理团队的核心，实际控制着公司，对公司的影响力广泛而重大。因此，探讨CEO如何影响公司的会计稳健性意义重大。 本文从我国2010-2014年的沪深A股上市公司出发，采用Ball和Shivakumar（2005）的模型研究我国上市公司CEO个人特征（年龄、性别、学历、专业、持股比例、两职兼任情况）如何影响上市公司的会计稳健性。此外 ...

The Hour that Never Comes and the Time that Remains
Journal of Analytical Psychology, EarlyView.Abstract This essay proposes a symbolic and clinical investigation of psychic temporality through two archetypal experiences of time: the hour that never comes and the time that remains. Drawing on analytical psychology, trauma theory and aesthetic philosophy, text explores how certain forms of suffering resist chronological resolution and persist as ...

Methods in Ecology and Evolution, EarlyView.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

Conservation Biology, EarlyView.Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e.

Conservation Biology, EarlyView.Abstract The Natura 2000 (N2K) network of protected areas is one of the main tools for area‐based conservation in the European Union (EU), yet its role in preserving plant biodiversity requires better understanding. We examined data kept in the European Vegetation Archive from over 1.2 million vegetation plots and obtained over 14.2 million plant ...

Super weakly compact sets and the super fixed point property in Banach spaces [PDF]
, 2015 我们知道,不动点理论是非线性分析及其应用的一个非常重要的组成部分.进入上世纪~60~年代以后,研究包括~Banach~空间中的有界闭凸子集对非扩张映射等的不动点性质成为不动点理论研究的主体,同时对这些映射的超不动点性质也是人们重点关注的内容.然而,由于超不动点性质研究要建立一种平行于弱紧集的“超弱紧集”理论,这就成为超不动点理论研究中的一大障碍.值得我们庆幸的是,近些年来超弱紧集的研究取得了重要进展,这使得我们进一步研究局部化的超不动点性质成为可能.

Conservation Biology, EarlyView.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Success of restoration strategies in preventing extirpation of 2 critically endangered coral species
Conservation Biology, EarlyView.Abstract An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected.

Hobbyist preferences for pet freshwater turtles
Conservation Biology, EarlyView.Abstract The burgeoning pet trade is a primary threat to wild freshwater turtles worldwide. Although the risks from commercial exploitation of turtles have been discussed widely, there is little empirical research on preferences for pet turtles from a hobbyists’ perspective.
