On‐Time Meal Delivery Assisted by Drone Resupply

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Ensuring timely delivery is crucial with the increasing competition in online meal delivery services. This requires the industry to adopt new technologies and the corresponding operational models, including the use of drones. Concerning the desired features of meal delivery, such as safety and reliability, we propose an operational model that ...

Self‐Service and Home Delivery Combined: Coordinating the Route of a Mobile Parcel Locker With the Delivery Tasks of Its Human Driver

open access: yesNetworks, EarlyView.
ABSTRACT In response to the increasing volume of parcels, last‐mile delivery innovations are exploring the integration of multiple delivery modes. The most prominent examples are delivery vans that, next to being the base for the delivery tasks of their human drivers, also function as mobile launching platforms for drones or autonomous delivery robots.

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

open access: yesOikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

open access: yesOikos, EarlyView.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...

Field location & marking of no-passing zones due to vertical alignments using the global positioning system [PDF]

open access: yes, 2008
Passing on two-lane roadways is one of the most difficult movements a driver may perform and guidance on where passing maneuvers are prohibited is given by the location of no-passing zones.

Conserving wildlife through demand reduction and supply alternatives: Two experiments in restaurants in Kinshasa

open access: yesPeople and Nature, EarlyView.
Abstract High aggregate levels of wildlife consumption in cities in Central Africa highlight the need for solutions that balance wildlife protection, local livelihoods and the relational values between people and nature. This study explores the impacts of demand‐ and supply‐side interventions on wild meat consumption through two randomized control ...

Technical wildness: Modernity, romanticism, and the technocratic turn in Scottish rewilding

open access: yesPeople and Nature, EarlyView.
Abstract Technical wildness is a new and increasingly influential culture of nature. This paper marks its emergence in Scotland in the early 2020s. Focusing on Scotland's rapidly evolving land management sector, the paper traces how private rewilding companies position science‐led land management and natural capital markets as the most effective ...

Sampling for Socially‐Inclusive Adoption Studies (SSAS): A new interdisciplinary sampling method for DNA‐fingerprinting‐based crop varietal adoption studies

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
DNA fingerprinting is becoming the standard measurement procedure in crop adoption studies in the Global South, yet the lack of systematic and intentional sampling regarding which farmer to go to the plot with may bias results from these methods. We introduce a methodological innovation, Sampling for Socially Inclusive Adoption Studies (SSAS), to offer

Development of a new microscopic passing maneuver model for two-lane rural roads [PDF]

open access: yes, 2015
Microsimulation is a useful tool to analyze traffic operation. On two-lane highways, the complexity of passing and the interaction with oncoming traffic requires specific models.
