Supervised visitation centers (SVCs) have developed rapidly across the United States. Increasingly, courts are restricting contact between abusive intimate partners and their children by ordering visitation or exchanges to occur at SVCs. This article describes some of the key lessons the authors learned over 18 months of planning and then another 18 months of implementation at a SVC developed s...

Plants often grow in clusters of various sizes and have a variable number of flowers per inflorescence. This small-scale spatial clustering affects insect foraging strategies and plant reproductive success. In our study, we aimed to determine how visitation rate and foraging behaviour of pollinators depend on the number of flowers per plant and on the size of clusters of multiple plants using D...

Despite considerable advances in our understanding of constraint composition, antecedent conditions, outcomes, and negotiation behaviors, few studies have tracked how constraints have changed or remained stable over time. This investigation sought to examine the change and stability in park visitation constraints and preferred constraint negotiation strategies across a 10-year period. A 2001 te...

Ongoing biodiversity decline impairs ecosystem processes, including pollination. Flower visitation, an important indicator of pollination services, is influenced by plant species richness. However, the spatio-temporal responses of different pollinator groups to plant species richness have not yet been analyzed experimentally. Here, we used an experimental plant species richness gradient to anal...

The objective of the TARGET VISITATION PROBLEM is to determine a path for an unmanned aerial vehicle that begins at a point of origin and needs to visit several targets before returning to its starting point. An optimal visitation sequence is one which minimizes the total distance traveled and maximizes the utility of the visitation order. This utility measure is defined for each pair of target...

Scientists have traditionally studied recreation in nature by conducting surveys at entrances to major attractions such as national parks. This method is expensive and provides limited spatial and temporal coverage. A new source of information is available from online social media websites such as flickr. Here, we test whether this source of "big data" can be used to approximate visitation rate...

Studies of pairwise interactions have shown that an alien plant can affect the pollination of a native plant, this effect being mediated by shared pollinators. Here we use a manipulative field experiment, to investigate the impact of the alien plant Impatiens glandulifera on an entire community of coflowering native plants. Visitation and pollen transport networks were constructed to compare re...

n early childhood home visitation programs, parents and children are visited at home during the child’s first 2 years of life by trained personnel who rovide some combination of information, support, or raining about child health, development, and care. ome visitation has been used to meet a wide range of bjectives, including improvement of the home envionment, family development, and the preve...

Native bees provide essential pollination services to cultivated and wild plants worldwide. Despite the need to conserve pollinators, the foraging patterns of native bees are poorly understood. Classic concepts of resource use have typically categorized bee species as specialists or generalists based on floral visitation patterns. While intraspecific variation in bee foraging likely depends on ...

BACKGROUND Obesity is a major problem in the United States, particularly among socio-economically disadvantaged Latino and Black children. Effective interventions that can be disseminated to large numbers of at-risk children and their families are needed. The goals of the Early Childhood Obesity Prevention Program (ECHO) are to examine the 12-month efficacy of a primary obesity prevention progr...
