Why is the video so wide?

The original videos are just over 1300 pixels wide. Although we can shrink them within the Web browser, that makes it difficult to perceive the details necessary for observational coding. (Facial expression and such.) If you're attempting to code the videos, you probably want to adjust your screen resolution and maximize your browser window.

How do I code my own dataset?

This site doesn't feature specialized software for creating your own dataset. In all likelihood, your best bet is to adjust your browser window to fill the top half of your screen and use Microsoft Excel in the lower half of your window to record your codes.

How were the microphones positioned?

In the video, you can see a black/silver pole interrupting the view. Atop that pole was a microphone that captured the students input. In addition, the teachers wore a microphone. You can switch between these audio tracks using the video player.

Why does the video appear to be distorted?

The distortion is the result of rendering all sides of the room into one long image, a segmented panorama.

Although the distortion is unusual at first glance, this view enables you to see the entire classroom without having to adjust the camera angle, which is very useful for observational coding.

Can I get access to higher-quality versions of the videos?

Unfortunately, the video you see on the site is the highest quality version of the video. After video processing (and compression), the original videos were destroyed.

How do I find data that I can use for my research project?

The Data Access/Download Data page allows you to search our data holdings by keyword. The page also gives you several options to browse our data holdings. On the search results page, you may filter your results by subject, geography, time period, funding agency, author, and recency.

Please keep in mind that our data collections consist of ASCII data files and documentation. These data files must be read into a statistical package such as SAS or SPSS in order to generate statistics. Our Web site does not have statistics that have already been produced or published reports, charts, or other analyses based upon data holdings. For more information about these products, see the answer to I don't want to run my own statistics. Where can I get reports or statistics that have already been generated?

What is MyData?

MyData is a user registration and authentication system for the ICPSR Web site. The system creates a more secure environment for users and enables them to sign up for services that ICPSR is developing. MyData has the following user-friendly features:

  • Uses an email address as a login ID
  • Requires a password to authenticate to the Web site
  • Allows users to create an account and set preferences
  • Allows registered users to reset a forgotten password
  • Enables users to view prior download history
  • Enables users to subscribe to an update notification service that emails users when a study they've previously downloaded is substantially updated

Do I have to establish a MyData account?

Users who desire to download members-only data and some publicly available data may either establish a MyData account or log in using their Facebook or Google account. When a user creates a new account, s/he will be asked to complete a brief questionnaire about user preferences. Users that do not want to share their name and contact information with the Official Representative at their member institution can request to withhold that information.

How does ICPSR handle authentication for access to its data and members-only content?

Users may log in to ICPSR using their Facebook or Google account. They may also use an ICPSR MyData account if they prefer not to use third party authentication.

Benefits of Third Party Authentication

  • Users will not have to remember a separate login/password to access ICPSR data.
  • If users are logged into their Facebook or Google account and then go to ICPSR, they will already be logged into ICPSR.

Privacy Issues

  • Using a single identity to log into multiple websites allows users to establish a reputation on several sites with the same ID. However, that may make it easier for others (marketers, law-enforcers) to track them.
  • Users can choose to share personal information they've stored at the third party provider with ICPSR, in order to save the trouble of re-entering some basic profile information.
  • If a third party account gets hacked, the hackers would also be able to access that user's ICPSR account.
  • Third party authentication providers are able to track every site you use your third party account to log into.

Multiple Logins

A user may log into ICPSR using (for example) Facebook one session, Google another session, and MyData a third session. Doing so would create separate profiles in the ICPSR system if the third party accounts are associated with different email addresses.

How do I obtain a data collection from NACJD?

Most NACJD data collections can be freely downloaded from our web site. Information about how to download data and documentation can be found in the Help section of this web site or users can contact NACJD staff for assistance at nacjd@icpsr.umich.edu.

Selected NACJD data collections cannot be downloaded from our web site due to the sensitive nature of the data. If you are only given the option to download the documentation but no data for a particular collection, then you should read the Restrictions field in the study description for more information about how to obtain the data. In order to ensure respondent confidentiality, certain sensitive data collections are available only through a restricted access archive. While these data are still available free of charge, users must specifically request these collections from the archive. More information about this process and the necessary Data Transfer Agreement Form can be found in our Restricted Access Data Archive as well as in the Restrictions field in the study description.

Why is the text so small on your Web site?

The default font size varies from browser to browser. We design our sites so that the user can control the font size. By doing this, we guarantee that users with low vision can access our content.

See "How to Increase the Font Size on My Browser" for assistance resizing the text in your preferred browser.

How can I archive crime or criminal justice data that I have collected?

If you are an NIJ grantee, please see Depositing Data Sponsored by the National Institute of Justice. All other researchers who would like to contribute data to the archive can submit their materials through ICPSR's data deposit procedures and the data will then be forwarded to the criminal justice archive. For more information, see our Deposit Data page.

Does ICPSR accept qualitative data?

Yes. Please contact ICPSR prior to submitting qualitative data at deposit@icpsr.umich.edu.
