Explaining the Allocation of Bilateral and Multilateral Environmental Aid to Developing Countries

In this paper we examine how international development assistance for environmental purposes is allocated to developing countries. In particular, we investigate whether there are patterned differences between environmental aid for international public goods projects versus environmental projects having more localized impacts. We empirically investigate these questions using project project level development assistance data.International Development,

A slowly rotating perfect fluid body in an ambient vacuum

A global model of a slowly rotating perfect fluid ball in general relativity is presented. To second order in the rotation parameter, the junction surface is an ellipsoidal cylinder. The interior is given by a limiting case of the Wahlquist solution, and the vacuum region is not asymptotically flat. The impossibility of joining an asymptotically flat vacuum region has been shown in a preceding work.Comment: 7 pages, published versio

Pharmacology of airway afferent nerve activity

Afferent nerves in the airways serve to regulate breathing pattern, cough, and airway autonomic neural tone. Pharmacologic agents that influence afferent nerve activity can be subclassified into compounds that modulate activity by indirect means (e.g. bronchial smooth muscle spasmogens) and those that act directly on the nerves. Directly acting agents affect afferent nerve activity by interacting with various ion channels and receptors within the membrane of the afferent terminals. Whether by direct or indirect means, most compounds that enter the airspace will modify afferent nerve activity, and through this action alter airway physiology

Superior Facial Expression, But Not Identity Recognition, in Mirror-Touch Synesthesia

Simulation models of expression recognition contend that to understand another's facial expressions, individuals map the perceived expression onto the same sensorimotor representations that are active during the experience of the perceived emotion. To investigate this view, the present study examines facial expression and identity recognition abilities in a rare group of participants who show facilitated sensorimotor simulation (mirror-touch synesthetes). Mirror-touch synesthetes experience touch on their own body when observing touch to another person. These experiences have been linked to heightened sensorimotor simulation in the shared-touch network (brain regions active during the passive observation and experience of touch). Mirror-touch synesthetes outperformed nonsynesthetic participants on measures of facial expression recognition, but not on control measures of face memory or facial identity perception. These findings imply a role for sensorimotor simulation processes in the recognition of facial affect, but not facial identity

Ground Water Occurrence and Utilization in the Arizona - Sonora Border Region

Authors' manuscript for published article / paper presented at Symposium on U.S.-Mexican Transboundary Resources, Part II. (publication information from WorldCat.)This article discusses ground-water resources along the Arizona-Sonora border from Yuma, Arizona to the Douglas-Rio Yaqui region in Eastern Arizona. Transfrontier physiography and geology are reviewed to understand the physical occurrence of ground water, its storage, movement, depth, and availability. The border region is divided into five zones or basins for ground-water supply; then the utilization of ground-water resources is detailed, including kinds of development and production water quality considerations, and present and future resource supply problems. Particular attention is paid to the extensive pumping proposals at San Luis, Sonora near the Colorado River. The need for better institutional arrangements to plan and manage the conjunctive use of both surface and ground-water supplies is discussed as a summary conclusion.This item is part of the Water Resources Research Center collection.

Outdoor Recreation and Rural Transitions in Central Appalachia: Revisiting the Economic Impact of Rock Climbing in Kentucky’s Red River Gorge

Kentucky’s Red River Gorge is a popular rock climbing destination located amid longstanding poverty in America’s Central Appalachian region. Climbing represents an important part of the outdoor recreation economy and may provide one alternative to mono-economic extractive industry dependency in this region. This study examines the economic impact of climbing in the Red utilizing an online survey of rock climbers and economic impact methodology. The survey examines expenditures in lodging, food purchases, travel, retail purchases, and services. The survey also collected visitation and demographics data. The authors estimate climbers spend $8.7 million annually (up from$3.8 million in 2015) and support over 100 jobs in some of the poorest counties in the region and nation. The study reiterates previous findings indicating climbers are well-educated with incomes higher than those typically found in this region. The study’s results help reframe the value of climbing’s economic impact in rural transitional economies throughout Central Appalachia. These findings also raise policy implications regarding public land access and reducing climber environmental impacts on public lands

Peer Influence in Initiation to Heroin Use

Much research on heroin initiation shows that most people use heroin initially with friends or family. However, there is little research examining why those who use heroin would initiate others to its use, and conversely, whether and why one might try to prevent initial heroin use in others. Following recent work on peer influence on crime and delinquency, we test the hypothesis that those with higher levels of self-control are less likely to initiate others to heroin use and are more likely to try to prevent others from using for the first time. The sample included 370 persons entering an opioid withdrawal program. We find that those with low self-control are more likely to initiate others, but there is no relationship between self-control and trying to prevent initiation. We further investigate self-reported motives for initiating others, and find a mix of self-interested and more altruistic motives for initiating others
