Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservation

Conservation Biology, EarlyView.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.

Which Decolonization? Theorizing Decolonization beyond Decoloniality and its Critics

Development and Change, EarlyView.
ABSTRACT The debate on decolonial thought has reached an unhelpful stalemate. A core problem in assessing decolonial thought is that the term ‘decolonization’ has been stretched so widely that it now allows for many competing uses. For some critics of decolonial thought such as Nigerian philosopher Olúfẹ́mi Táíwò, this overuse points to conceptual ...

Research on Dynamic Characteristics of the Two-stage Planetary Gear Transmission System of TBM Reducers

Jixie chuandong
Tunnel boring machine (TBM) reducers are important components of TBM's cutter-head drive system. In order to reveal the dynamic characteristics of the two-stage planetary gear transmission system of the TBM reducer, the influence factors such as tooth ...

Antinomies of Nativism: Understanding Decoloniality Theory's Affinities with the Global Far Right

Development and Change, EarlyView.
ABSTRACT This article examines the peculiar conjuncture of decolonial theory and contemporary far‐right ideology. It argues that their shared fixation on the dualism of native and settler is immanent to the development of advanced capitalism, particularly the sharpening of its contradictory tendency to undermine labour as the source of value, and to ...

Kineto-static Analysis of Planetary Gear Train based on Vector Bond Graph Method

Jixie chuandong, 2016
For the problem of kineto- static analysis for planetary gear train,the corresponding vector bond graph procedure is proposed. Based on the kinematic constraint condition of planar compound revolute joint,the procedure for modeling planar compound ...

New organizational forms: Deconstructing and reconfiguring the literature

European Management Review, EarlyView.
Abstract Less hierarchical, self‐managing, agile, alternative: so‐called “new organizational forms” draw interest from scholars and practitioners alike. Despite an abundance of both conceptual and empirical research, the “new organizational form” concept remains elusive, capturing a growing diversity of phenomena and labels.

Study on the Dynamics of Non-circular Planetary Gear Hydraulic Motor

Jixie chuandong, 2017
The structure and working principle of a new type of non-circular planetary gear hydraulic motor are introduced. The pitch curve and tooth profile of each gear within non-circular planetary gear system are programmed. A torsional vibration model is built

Residency and Space Use of Endangered Smoothhound Sharks (Mustelus mustelus) in Relation to Marine Protection and Demersal Longline Fishing Along South Africa's South Coast

Fisheries Management and Ecology, EarlyView.
ABSTRACT Shark populations are declining globally and the effectiveness of marine protected areas (MPAs) as a conservation tool may vary by species and environmental context. This study assessed space use and residency of smoothhound sharks (Mustelus mustelus)—an endangered, yet highly exploited shark—in relation to spatial protection and fishing risk ...
