Minimal impact of spotted hyenas on livestock and endangered species in a prey‐rich ecosystem

Wildlife Biology, EarlyView.
The diet of large carnivores is of great interest to conservation managers, as it can reveal the extent of human–carnivore conflict and the impact of carnivores on species of high conservation priority. Metabarcoding of environmental DNA can identify species and is often more reliable than observational or morphological methods, particularly when it ...

Analysis of Influence Factor of Oil Jet Lubrication Impingement Depth of Aviation Spur Gear

Jixie chuandong, 2017
When the nozzle is decorated without offset and incline,gears with transmission ratios above 1 won’t be efficiently lubricated. In order to solve this problem,analytic method is adopted to establish mathematical model,basing on the geometric relationship

Forty years of captive breeding in Przewalski's horse: pedigree‐based insights into population growth, sex ratio, and inbreeding

Wildlife Biology, EarlyView.
Long‐term captive breeding programs play a critical role in the conservation and reintroduction of endangered species, yet they face persistent challenges related to demographic structure and genetic management. The Przewalski's horse Equus przewalskii, once extinct in the wild, represents a global model for conservation breeding supported by pedigree ...

Lost traditions and new pathways: Hunting participation and perceptions among Black HBCU students in the U.S.

Wildlife Society Bulletin, EarlyView.
Abstract The U.S. Fish and Wildlife Service's Relevancy Roadmap urges wildlife agencies to engage nontraditional audiences in activities such as hunting, yet little research has examined young Black Americans’ perceptions of and participation in hunting.

Collaborating in future states—Contextual instability, paradigmatic remaking, and public policy

Australian Journal of Public Administration, EarlyView.
Abstract Collaboration is ubiquitous in public policy life, with its presence and profile determined by prevailing governance conditions. Commitments to globalisation and marketisation in the latter part of the 20th century marked the onset of an era defined by collaboration, between and across tiers and spheres of government, with non‐state actors ...

Design of high contact ratio spur gears cut with standard tools

, 2003
In high precision and heavily loaded spur gears, the effect of gear error is negligible, so the periodic variation of tooth stiffness is the principal cause of noise and vibration.

Crisis, temporality and governmental policy agendas: The cases of Finland and Sweden

Scandinavian Political Studies, EarlyView.
Abstract Crises transform the temporal orientation of political decision‐making. They demand immediate and decisive action and thus convert time into a means of political control. In these circumstances, assessing the long‐term consequences of proposed policies with respect to welfare, sustainability or justice also becomes demanding.

Fatigue resistance of steel and titanium PVD coated spur gears

, 2007
The aim of this work is to investigate into the possibility of enhancing the fatigue resistance of CrN-PVD coated components. In particular, PVD coated spur gears were tested and a numerical simulation of crack propagation was carried out.

The company you keep: becoming one(self) in an Indonesian convent En bonne compagnie : devenir (quelqu’)un dans un couvent indonésien Pergaulan dalam biara di Indonesia: sebuah proses pembentukan diri*

Journal of the Royal Anthropological Institute, EarlyView.
This article investigates companionate processes of self‐making in a religious community of Catholic nuns in eastern Indonesia. I argue that the sociality of the convent establishes a unique context for understanding the effects of one's company on processes of self‐becoming.
