Safe Curb Parking Distance Near School-Gate Ensuring Child Pedestrians' Safety

open access: yesTransactions on Transport Sciences
The presence of curb parking near school-gate is a serious threat to the safety of child pedestrians while crossing the road. Child pedestrians with limited discernibility often cannot sense an approaching vehicle obstructed by the parked vehicle(s).

Modeling of Unsymmetrical Single-lane Roundabouts based on Stopping Sight Distance

open access: yesKSCE Journal of Civil Engineering, 2019
Evaluation of the adequacy of sight distance at roundabout is usually performed graphically as no quantitative guidelines are available for the lateral clearance needs. This paper presents analytical lateral clearance models to satisfy Stopping Sight Distance (SSD) at unsymmetrical single-lane roundabouts (with different entry and exit radii).

Potential vs. Realized Large Carnivore Density: The Influence of Livestock on Carnivore Carrying Capacity Estimation

open access: yesAnimal Conservation, EarlyView.
In an unfenced mixed‐use savanna landscape in Namibia, we compared realized densities of leopards and cheetahs estimated using spatial capture–recapture models with prey‐based carrying capacity predictions. Leopard densities exceeded predictions based on wild prey alone but closely matched livestock‐supplemented models, suggesting that vulnerable ...

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Sight Distance Detection Using LIDAR and GPS Data

open access: yes
Sight distance (SD) is important subject of traffic safety. Depending on SD driver is able to receive in time the necessary visual information about any obstacles on the road. Obstacle on road must be spotted in defined distance, so the driver could make

Bonds, Bounds, and Borders: Crafting Hospitality with Unauthorized Migrants in Southern France

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT This article analyzes the everyday politics of migrant hospitality in rural Southern France. Drawing on four years of fieldwork alongside benevolent residents hosting unauthorized migrants at their home or volunteering in migrant shelters, I consider how residents attempted to make up for the state's abandonment of migrant lives, the ethical ...

Evaluation of the Intersection Sight Distance at Stop-Controlled Intersections in a Mixed Vehicle Environment

open access: yesWorld Electric Vehicle Journal
The introduction of autonomous vehicles (AVs) on roadways will result in a mixed vehicle environment consisting of these vehicles and manual vehicles (MVs). This vehicular environment will impact intersection sight distances (ISDs) due to differences in the driving behaviors of AVs and MVs. Currently, ISD design values for stop-controlled intersections

Traffic Sign Sight Distance for Low-Volume Roads

open access: yes, 2011
Warning signs are a critical signaling element providing information to the monitoring public with respect to potential hazards on the roadway. They should be placed in order to allow the driver enough time to perceive, identify, and decide on and ...

The Vicissitudes of the Nafs: Madness, Paralysis, and the Work of Transgression in Sufi Ethics

open access: yesAnthropology of Consciousness, EarlyView.
ABSTRACT How should we theorize Sufi ethics when the practice of zikr (remembrance) that leads to spiritual enlightenment (tazkiyya) might also bring one to the brink of majzubiyat (madness)? What forms of regulation or restraint are imagined or enacted by practitioners to prevent spiritual boundlessness from perverting into its underside of paralysis (
