Large, terrestrial carnivores are key regulators exerting strong and irreplaceable effects on biological community assemblages, their absence can lead to fundamentally downgraded ecosystems (Estes et al. 2011, Enquist 2020). Due relatively low reproductive rates high energetic requirements, large predators also among the most imperilled species Earth highly sensitive human-induced environmental...

We have investigated the effects of inhaling odors of preference on physiological responses to physical exercise in college students. Rhythmic handgrip, maintaining a mercurial pressure by repetitive compression, increased blood pressure. In the participants exercised with inhaling odors of their choice, such as rose, jasmine and lavender, the increase in diastolic blood pressure during exercis...

This article examines the history of human exposure to silica, the second most common element on earth, to explore the problem of categorizing substances for regulatory purposes and the role interest groups play in developing policy. The regulatory history of silica teaches three important lessons: First, the most compelling account of the cycle of action and inaction on the part of regulators ...

Quantitative differences in leaf abscisic acid (ABA) among Acer rubrum L. (red maple) ecotypes were investigated. This study tested the hypothesis that seedlings from wet and dry maternal sites display distinctly different capacities to synthesize ABA in response to atmospheric vapor pressure defi cits. The increased levels of ABA in leaf tissue in the red maple ecotypes were associated with at...

This paper examines recent foreign policy and the changing orientation to ‘Asia’ and ‘Asian engagement’. It is argued that despite the general constraints faced by the policy-making elites of smaller powers in an era of ‘globalization’, policy matters. In this regard, recent policy under the Howard government provides a stark contrast to the earlier, proactive, Asia-oriented policies of the Haw...

The Center for Robot-Assisted Search and Rescue deployed three commercially available small unmanned aerial systems (SUASs)—an AirRobot AR100B quadrotor, an Insitu Scan Eagle, and a PrecisionHawk Lancaster—to the 2014 SR-530 Washington State mudslides. The purpose of the flights was to allow geologists and hydrologists to assess the eminent risk of loss of life to responders from further slides...

We describe algorithms for automating the process of picking seismic events in prestack migrated common depth image gathers. The approach uses supervised learning and statistical classification algorithms along with advanced signal/image processing algorithms. No model assumption is made such as hyperbolic moveout. We train a probabilistic neural network for voxel classification using event tim...

Both fear and pain can cause suffering. When pain is being studied, experiments must be designed to separate the variable of fear from the variable of pain. Some investigators claim that a sharp cut off line exists between those animals who experience pain and suffering, from those who do not. These arguments are based on the assumption that the capacity to suffer is related to the size and com...

In 1925 the Carnegie Corporation granted $50,000 to Louisiana, a state then “backward in library development,” to fund a demonstration of rural public library development. Essae M. Culver, a California librarian, was chosen to direct the project. Culver arrived in Louisiana to fi nd that the entire state needed organizing. She concluded that the parish (county) was the appropriate unit upon whi...

The aim of this article is to examine the role of information technologies (IT) in supporting practice and professional identity formation, both major axes for communities of practice. The article uses an ethnographic case study to understand how public defenders learn to improve their court performance. The concept of “communities of practice” helps to illuminate how the attorneys in a public ...
