Will the Kyoto Protocol Be Good for the Environment? Implications for Agriculture
Global warming or, more accurately, climate change remains a hotly debated issue in scientific, government and public circles. While the extent of the human contribution to climate change through greenhouse gas (GHG) emissions remains highly controversial, the scientific evidence of significant changes in climate per se appears to be mounting (Intergovernmental Panel on Climate Change, 2001). Since changes in climate typically will include greater variability in temperatures, more extreme weather events and changes in precipitation patterns as well as a general warming trend, there are significant risks for agriculture.(2) If human activity does turn out to have a significant causal effect on climate change, the Kyoto Protocol and other related multilateral environmental agreements appear to have the potential to reduce these risks. The Kyoto Protocol, however, leaves possible channels for increases in emissions or so-called carbon leakage.Environmental Economics and Policy,
An Investigation Of Principals\u27 Attitudes Toward The Knowledge And Use Of Learning Styles In Therapeutic Settings
In March, 2006 the Principal\u27s Attitudes Toward the Knowledge, Value, and Application of Learning Styles with Students in Therapeutic Settings survey developed by the author was distributed to 120 principals belonging to the National Association of Therapeutic Schools and Programs. Two mailings yielded a return of 68 (56.6%) usable survey instruments from which principals\u27 self-reporting on knowledge, value and application of learning styles was examined. Focus for this study was provided through three research questions: (a) to determine to what extent principals in therapeutic settings self-reported general knowledge of learning style applications, (b) to determine to what extent principals exhibit positive attitudes toward the use of learning style theory- supported instructional methods and materials, and (c) to determine to what extent principals in therapeutic settings support the application of learning style theory. All administrators reported general knowledge of learning style theories, three basic learning styles, and matching teaching strategies with learning styles. All administrators believed that students do exhibit different learning styles, learning styles have a place in education, and teachers should receive learning style training. They also expressed the belief that learning styles impact student learning, matching teaching strategies to learning styles was important for academic success, a learning style inventory was necessary, and matching mental health disorders to learning styles was important for academic achievement. The most documented change due to learning style-based instruction was evidenced by test scores and earned grades. All administrators wanted to learn more about learning styles. Almost 90% of administrators indicated that they were providing learning style training. Almost 100% (95.6%) reported they observed improvement on academic achievement due to learning style-based instruction
Constraints on the broad line region from regularized linear inversion: Velocity-delay maps for five nearby active galactic nuclei
Reverberation mapping probes the structure of the broad emission-line region
(BLR) in active galactic nuclei (AGN). The kinematics of the BLR gas can be
used to measure the mass of the central supermassive black hole. The main
uncertainty affecting black hole mass determinations is the structure of the
BLR. We present a new method for reverberation mapping based on regularized
linear inversion (RLI) that includes modelling of the AGN continuum light
curves. This enables fast calculation of velocity-resolved response maps to
constrain BLR structure. RLI allows for negative response, such as when some
areas of the BLR respond in inverse proportion to a change in ionizing
continuum luminosity. We present time delays, integrated response functions,
and velocity-delay maps for the broad emission line in five
nearby AGN, as well as for and in Arp 151,
using data from the Lick AGN Monitoring Project 2008. We find indications of
prompt response in three of the objects (Arp 151, NGC 5548 and SBS 1116+583A)
with additional prompt response in the red wing of . In SBS
1116+583A we find evidence for a multimodal broad prompt response followed by a
second narrow response at 10 days. We find no clear indications of negative
response. The results are complementary to, and consistent with, other methods
such as cross correlation, maximum entropy and dynamical modelling. Regularized
linear inversion with continuum light curve modelling provides a fast,
complementary method for velocity-resolved reverberation mapping and is
suitable for use on large datasets.Comment: 20 pages, 13 figures, accepted to MNRA
