In many schools, drugs, vandalism, assaults,
thefts, and violence against both students and teachers
have destroyed the orderly atmosphere needed for teaching
and learning. While juvenile criminal behavior,
both in school and elsewhere, is caused by a large and
complex set of sociological and psychological conditions,
there is evidence that...
John Keats, as a principal figure in the Romantic
movement in Europe, reacted against the philosophy of the
Enlightenment. His poetry and letters are testament to his
distrust of, and resistance to, an ever increasingly
clinical and "reasonable" society. Keats's poetic thought--imaginative,
speculative, dialectic--is the antithesis of an
Enlightenment philosophy...
Understanding the frequency, magnitude, and nature of explosive volcanic eruptions is essential for hazard planning and risk mitigation. Terrestrial stratigraphic tephra records can be patchy and incomplete due to subsequent erosion and burial processes. In contrast, the marine sedimentary record commonly preserves a more complete historical record of volcanic activity...
Barley (Hordeum vulgare L.) possesses a large and highly repetitive genome of 5.1 Gb that has hindered the development of a complete sequence. In 2012, the International Barley Sequencing Consortium released a resource integrating whole-genome shotgun sequences with a physical and genetic framework. However, because only 6278 bacterial artificial chromosome...
Marine provinces, founded on contrasting floras or faunas, have been recognized for more than 150 years but were not consistently defined by endemism until 1974. At that time, provinces were based on at least a 10% endemism and nested within biogeographic regions that covered large geographic areas with contrasting biotic...
Glacial periods exhibit abrupt Dansgaard-Oeschger (DO) climatic oscillations that are thought to be linked to instabilities in the Atlantic meridional overturning circulation (AMOC). Great uncertainty remains regarding the dynamics of the DO cycle, as well as controls on the timing and duration of individual events. Using ice core data we...
The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive
conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife
species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...
This document describes the design and deployment of a first generation water vapor density sensing unit, the HumiSense. This device is based on an open, air-filled capacitor which is part of a resonant circuit. The frequency of the resonant circuit mixed with a fixed frequency oscillator is the basis of...
