Generalized preinvex functions and related Hermite-Hadamard type integral inequalities on fractal space(分形空间中的广义预不变凸函数与相关的Hermite-Hadamard 型积分不等式)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2019
在分形集Rα (0 < α ≤ 1) 上定义了广义预不变凸函数,建立了关于广义预不变凸函数的Hermite- Hadamard 积分不等式。构建了一个与广义预不变凸函数相关的局部分数阶积分恒等式,由此恒等式并利用广义 Hölder 不等式和广义幂均不等式得到了关于此类函数的几个Hermite-Hadamard 型局部分数阶积分不等式。结果推广了已有研究中的一些结论。

Sign Language as “Mother Tongue Orphan”: A Challenge to Raciolinguistic Multiculturalism in Singapore

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT This article examines the contested status of “sign language” in Singapore by exploring deaf people's experiences of the “Mother Tongues”—the state's designation for the official languages of Mandarin, Malay, and Tamil—with a particular focus on the relationships that deaf Chinese Singaporeans have with Mandarin.

On the normative roles of biodiversity and naturalness in conservation

open access: yesConservation Biology, EarlyView.
Abstract Nature is an opaque concept. Consequently, the term biodiversity conservation has replaced nature conservation in most conservation contexts. We review the conceptual indeterminacies that plague the terms nature and natural but then show that comparable difficulties plague biodiversity.
