Welcome to AccessScience News!
AccessScience News, based on the McGraw-Hill Encyclopedia of Science and
Technology Online, is a free monthly citation of current science updates
available on AccessScience. Our goal is to keep you abreast of the
newest content and features of AccessScience.
New & Noteworthy
<http://www.accessscience.com/Newsletter/images/label-newnoteworthy.gif>
* The reformatted user statistics are now online and should be
accessible "24/7" by the designated contact person for AccessScience at
your library using the same URL, user name, and password as before.
After log-in, links are available to reports for Session Data, Accesses
to Articles by Topic, and Accesses to Content Areas by Categories. These
data report usage starting December 15, 2003. An additional link to view
statistics prior to December 15, 2003, is provided.
The "Session Data" report captures home page accesses and total accesses
for your institution (for institutions that subscribe on a
concurrent-user basis, "Max connection errors" indicates number of times
that the user limit had been exceeded); "Accesses to Articles by Topic"
reports total accesses in each of the 19 topics; and "Accesses to
Content Areas by Categories," reports total accesses by content type
(e.g., Encyclopedia articles, Research Updates, biographies).
These reports are further divided into "daily" data showing usage for
the previous 24 hour period; "weekly" data reporting on usage since the
previous Sunday; and "monthly" data (please refer to the historical
report mentioned above for data prior to December 15, 2003).
The report on accesses by category after December 15th may show a slower
rate of growth for Encyclopedia articles compared with the other content
categories. This would result from the new algorithm used to display
Encyclopedia articles, which makes viewing more convenient but reduces
the access count for long articles. We also have split up some general
categories to show use of special features, such as the Image Gallery.
As always, these reports may be downloaded in Excel or tab-delimited
database format.
* The new "email this article" feature allows users to send an
e-mail message containing a link to a full-text, fully illustrated pdf
version of an article to themselves at another location or to another
person. This is useful if the user wishes to view the article in a
location where subscription access is not available, or if printing
services are not available.
* We recently published a new exhibit in our Image Gallery,
Supernova remnants
<http://www.accessscience.com/server-java/Arknoid/science/AS//ImageGalle
ry/1837/exhibit_toc.html> , with 19 optical, x-ray, and radio telescope
images from international observatories and orbiting platforms, and an
overview article on these products of the explosive death of stars by
Prof. Stephen Lawrence, Department of Physics & Astronomy, Hofstra
University. Once again, the images may be downloaded in PowerPoint
format for classroom use; this exhibit also includes a QuickTime
animation.
* The Question of the Week announcement on the home page links to
the latest AccessScience Q
<http://www.accessscience.com/server-java/Arknoid/science/AS//QA/> &A.
Each week, we select a particularly interesting question submitted by a
reader and ask a prominent scientist to write a brief response with
links to relevant articles in AccessScience for in-depth reading. A
listing of recently published as well as upcoming Q&A's is given below.
* If you plan to attend the Public Library Association meetings in
Seattle, please make sure to visit the McGraw-Hill exhibit (Booth 341).
We look forward to your comments and feedback about AccessScience and
the McGraw-Hill Encyclopedia of Science & Technology. And when you
visit, enter the drawing to win an Apple iPod! Just fill out the entry
card you'll find in the "Aisle x Aisle Show Program" and drop it off
when you visit our booth. Exhibit hours are:
Wednesday, Feb 25, 4:00pm-6:30pm
Thursday, Feb 26, 8:30am-5:00pm
Friday, Feb 27, 8:30am-4:00pm .
New Articles
<http://www.accessscience.com/Newsletter/images/label-newarticles.gif>
* Autism
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_040835_frameset.html> , by Dr. Robert Byrd, Associate Professor
in Clinical Pediatrics, University of California, Sacramento. Autism is
a neurodevelopmental condition that impairs the way a person relates to
and communicates with other people. Although recognition of autism is
increasingly common, the cause and the reason for its increase remain
unknown. This timely article reviews:
diagnosis-etiology-genetics-prenatal and perinatal
factors-theories-autism spectrum disorders-Asperger syndrome-Rett
syndrome-childhood disintegration disorder-epidemiology-interpretation
of observed increase-treatment. Literature references and links to
relevant web sites supplement the text.
* Crab
<http://www.accessscience.com/server-java/Arknoid/science/AS//ResUpdates
/2004/YB_040545_frameset.html> nebula, by Dr. Paul Scowen, Department of
Physics and Astronomy, Arizona State University, Tempe. The Crab Nebula
is the product of a powerful explosion that blew apart a giant star and
was seen by Chinese astronomers in 1054. It has been intensively
studied, most recently with both the Hubble Space Telescope and the
Chandra X-ray Observatory. This article discusses the observations made,
the dynamics of the nebula, and the results of imaging, and concludes
with an overall picture of the patterns and processes of the nebula. An
extensive bibliography is complemented by links to external websites.
* Digital
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_041195_frameset.html> stroboscopic photography, by Prof. Andrew
Davidhazy, School of Photographic Arts and Sciences, Rochester Institute
of Technology, New York. This well-illustrated article discusses
traditional and digital photographic techniques for capturing high-speed
motion ("time-sampled image recording").
* Geoarcheology
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_040710_frameset.html> , by Prof. George Rapp, Jr., Dean, College
of Letters and Science, University of Minnesota. Geoarcheology entails
the use of geologic concepts, methods, and knowledge for solving
archeological problems. New instrumental techniques adapted from physics
and chemistry, such as ground-penetrating radar, are also used. This
article reviews this field including prospecting techniques, provenance
and age analysis, and sediments and soil analysis.
* Higgs
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_040100_frameset.html> boson, by Prof. Chris Quigg, Associate
Director, Superconducting Super Collider, Lawrence Berkeley Laboratory,
California. A highly readable account of the search for an elementary
atomic particle that is predicted by the theory of electromagnetic and
weak interactions and is believed to be associated with the origin of
mass of all known elementary particles.
* Indoor
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_040315_frameset.html> fungi, by Dr. Brian G. Shelton, PathCon
Laboratories, Norcross, Georgia. The author explains that the spores of
fungi, so common in outside air, can be easily transported indoors
through windows, doors, ventilation systems, etc. With the use of
stunning color photomicrographs, the article discusses: occurrence and
conditions for growth of common indoor molds-effects on human
health-allergic reactions-asthmatic reactions-infections-removal and
control.
