  • Violence, abuse and neglect”

This resource contains articles from 1980 to the present and is updated monthly.

To access Social Services Abstracts from IU Northwest campus computers ONLY, go to the IU Northwest Electronic Information Page . Under the Journal and Newspaper Indexes heading, click the Humanities and Social Sciences link. At the next screen, choose Social Services Abstracts to start using this journal index. If you need further assistance using the database, there is a Help button located at the top right corner of the main menu.

Four New Knovel Chemistry Titles Now Available Electronically

The IU Northwest Library is pleased to announce access to four new online chemistry references published by Knovel. These new references give students and faculty the ability to quickly locate key information about the properties of chemical compounds. You may access these resources using any computer that is a part of the IU Northwest campus network. Simply launch your Web browser and visit www.knovel.com.

International Critical Tables of Numeric Data, Physics, Chemistry and Technology, 7 volumes and index (first electronic edition). Originally published for the National Research Council, ICT offers data on physical, thermodynamic, mechanical, and other key properties and is a major reference source used by those involved in chemistry, physics, and engineering. Many tables have been “knovelized” to be interactive. The full text of the original print version is available in PDF format (full-text searchable), including the original index. All entries in the index are hyperlinked to their page numbers.

knovel Critical Tables.  kCT is a brand new reference featuring tables of properties for commonly used chemical compounds in the physical properties tables. kCT has expanded the original 6,000 chemical compounds in the physical properties tables of International Critical Tables to more than 13,000 compounds. Using multiple sources, kCT contains the most up-to-date chemical properties information available online. Tables in kCT include Basic Physical Properties of Inorganic Compounds, Basic Physical Properties of Organic Compounds, Critical Properties and Acentric Factor, Enthalpy of Formation, Enthalpy of Vaporization, Entropy of Formation, Entropy of Gas, Gibbs Energy of Formation, Heat Capacity of Gas, Helmholtz Energy of Formation, Internal Energy of Formation, Basic Physical Properties of Common Solvents, and Safety Properties of Common Solvents. New tables will be added to kCT on a regular basis, setting the standard for online interactive chemical properties information.

Thermochemistry of the Chemical Substances. Compiled by renowned thermodynamicist, Frederick D. Rossini, and International Critical Tables editor F. Russell Bichowsky, this reference is a revision of the table of values for the heats of formation in the thermochemistry section in International Critical Tables. It includes 5,840 values of heats of formation and 350 values of heats of transition, fusion, vaporization, and reaction. All entries in the index are hyperlinked to their page numbers.

Smithsonian Physical Tables (ninth revised edition). Comprising 901 tables concentrating on a broad scope of common physical and chemical data, the information provided is of general interest to scientists and engineers, and of particular interest to those involved with physics in its larger sense. On knovel, the Smithsonian Physical Tables are now easy to navigate and full-text searchable (as are all references on knovel!). All entries in the index are hyperlinked to their page numbers.

Favorite Web Sites: General Science

The web sites featured this month have been critically evaluated and selected by the IU Northwest librarians as well as a group of academic and public librarians across the United States who compile a yearly Best Free Reference Web Sites List  for the American Library Association  . Here is a list of selection criteria  initially created by the MARS Best Free Websites Task Force to choose these sites. The Library hopes our readers will find these web sites useful for locating reliable, accurate and authoritative information on the Internet. The Elemental Data Index provides access to online scientific data from the NIST Physics Laboratory  for each specific chemical element. There are three versions of the index: frames, no-frames, and text-only. In all three versions, you search by clicking on the element in the periodic table. The results screen displays the element's atomic weight, ionization energy, ground-state level, and ground-state configuration, as well as links to all of the NIST databases in which that element appears, including Atomic Spectra Data, X-Ray and Gamma Ray, Radiation Dosimetry Data, Nuclear Physics Data, and Condensed Matter Physics Data. The information on this site serves as a complement to the WebElements Periodic Table (www.webelements.com) selected for the MARS Best 2001 list. (Summary used with permission of the MARS Best Free Websites Committee) The Geographic Names Information System (GNIS) home page notes that the site "contains information about almost 2 million physical and cultural geographic features in the United States."  The GNIS is searchable by name, state or territory, feature type (e.g., cemetery, beach, hospital), county, elevation, and population. Results pages provide longitude and latitude, USGS map names, elevation (if applicable), estimated population of cities and towns, and links to online maps. To search GNIS, follow the links in the table below the words "Query the GNIS Online Data Bases" and search the U.S. or Antarctica. The site is easy to search and the results are linked to the U.S. Census Bureau's map server.  (Summary used with permission of the MARS Best Free Websites Committee) Although the main purpose of this award-winning governmental site is to disseminate "information about the U.S. and worldwide Human Genome Projects," it actually offers a wealth of general research information on genetics and bioethics. Clicking on the "About HGP" link will lead to yet more links, including a "Genetics 101" introduction, a glossary of terms, a list of acronyms, a FAQ section, and an extensive list of links to other genome web pages. From the home page, the "Ethical, Legal, Social Issues" section includes a very useful page on legislation and links to journal articles on court actions. Site organization is generally good with alphabetic quick links at the top of the dictionary pages for easy navigation. A drawback of the design is that some of the sections are just long lists of articles and are a little difficult to wade through. Overall, however, this site is an excellent starting point for research on the hot issues in bioethics. (Summary used with permission of the MARS Best Free Websites Committee) WebElements is an award-winning online periodic table. There is a Scholar Edition for students as well as a Professional Edition. Researchers click on the symbol for any element on the periodic table displayed on the home page. Information given for each element includes the name for the element in several languages, essentials (name, symbol, atomic weight, etc.), description, and isolation. Sidebars provide well-known compounds that contain the element and more detailed information on the element’s properties and history. The Scholar Edition, at http://www.webelements.com/webelements/scholar/index.html, provides more pictures demonstrating element structures and periodic properties. Both versions are excellent teaching tools as well as helpful ready reference resources. (Summary used with permission of the MARS Best Free Websites Committee) Topozone.com is an online map service providing topographical maps of the United States, down to the [quadrant] level: 1:100,000, 1:25,000, and 1:24,000. These maps do not provide most street names, but they do include features such as buildings, streams, woods, creeks, mountains, and of course, topographic contour lines. The maps will print out most successfully on a color printer, but will still be useful in black and white. Use of Topozone along with Mapquest or another street map tool would provide quite complete information on both natural and man-made features.

A collection of articles written by Marshall Brain, who, according to the web site is "nationally recognized for his ability to communicate complex ideas clearly." The articles describe how common "stuff," such as how an appendix, electricity, car engines, modems, etc. work. Both fun and informative, the articles contain exceptionally simple and descriptive graphics and numerous links to relevant information throughout. It features a table of contents and a search engine to help move around but a better web design would greatly improve access to this gold mine of information.
