Substrate‐Controlled Enantiodivergence in Ni‐Catalyzed Access to Phosphorylated Oxindoles With Quaternary Stereocenters

open access: yesAngewandte Chemie, EarlyView.
An efficient, enantiodivergent synthesis of phosphorylated oxindoles with quaternary stereocenters is achieved via a nickel‐catalyzed intermolecular Heck‐phosphorylation cascade. Employing a single chiral catalyst, either product enantiomer is selectively accessed simply by changing the alkene leaving group. DFT calculations trace this stereodivergence

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia

open access: yesConservation Biology, EarlyView.
Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Examining the multi‐disciplinary origins of biophobia towards threatening and non‐threatening wildlife in a highly urbanised city in China

open access: yesPeople and Nature, Volume 8, Issue 7, Page 2338-2352, July 2026.

從家課的質與量看香港課程改革的實施 The Quality and Quantity of Homework in Hong Kong Primary Schools: An Indicator of Curriculum Reform Implementation

open access: yesJournal of Curriculum Studies, 2014
華人地區深受傳統儒家文化影響,不少家長及教師都認同「勤有功、戲無益」、「有志者、事竟成」和「鐵柱磨成針」等傳統觀念。因此長期以來,香港學童都面對家課量多、家課深、長時間做家課的問題。2001年,香港特區政府推行教育改革,建議學校適當編排學生家課的數量,從而提升教與學的質素。為求了解香港學童家課的質與量是否因家課政策的實施而得以改善,本研究在香港10所小學進行調查,邀請各所學校其中一班五年級學生填寫問卷,統計完成家課的時間和家課類型,並訪問教師了解他們在家課設計、家課類型、家課功能等方面的考量。研究顯示 ...
