Scent stations are assumed to be a simple and economical method to index furbearer populations, but recent literature challenges the reliability of this technique. We examined several variables that could affect visitation rates of 2 commonly indexed species. Raccoon (Procyon lotor) and bobcat (Felis rufus) visitation rates of scent stations were monitored on the Hatchie National Wildlife Refug...

This article documents the successful creation and promotion of a bill to fund a nurse home visitation program for high-risk mothers in Arkansas. It illustrates several key factors in successful advocacy by pediatricians working in an academic setting: a realistic time commitment; a community needs assessment, data assimilation, and review of existing resources; the identification and incorpora...

Limitations of Home-Visiting Programs T use of home visitors to deliver services designed to improve the well-being of children and their families has drawn the increasing interest of policymakers, including President Barack Obama, who last year proposed a federal investment of more than $8 billion over the next 10 years in programs that use home visitation as a method of service delivery. Mean...

Home visitation services for young and expectant families have the potential to improve child and parent outcomes in a broad variety of ways, but the effectiveness of home visits may depend on the nature, frequency, and duration of these services. The Patient Protection and Affordable Care Act of 2010 (PPACA) created a new federal funding stream to promote the development and implementation of ...

Plants use many means to attract pollinators, including visual cues and odor. We investigated how nonpigment floral chemistry influences nectar removal, floral visitation, florivory, rates of outcrossing, and fitness through both male and female functions. We blocked expression of biosynthetic genes of the dominant floral attractant [benzyl acetone (Nachal1)] and nectar repellent [nicotine (Nap...

This contribution addresses the consideration of time windows in the optimization of multi-commodity network flows. For each node, one interval is specified in which the visitation is allowed. Applications in freight flow consolidation let this problem become interesting. An optimization model is proposed and a construction heuristic is presented. For improving the generated solutions, a geneti...

We investigate subdiffusion in the quenched trap model by mapping the problem onto a new stochastic process: Brownian motion stopped at the operational time S(α) = ∑(x=-∞)(∞) (n(x))(α) where n(x) is the visitation number at site x and α is a measure of the disorder. In the limit of zero temperature we recover the renormalization group solution found by Monthus. Our approach is an alternative to...

This study explores the feasibility of implementing a sustainable funding mechanism for ocean and coastal management in Jamaica. Results show that tourists are more willing to pay for an ‘‘environmental tax’’ than a general ‘‘tourism development tax’’. The study found that an environmental surcharge of US$2 per person could generate $3.4M per year for management with 0.2% rate of decline in tou...
