The U.S. Geological Survey (USGS) Library, where the author serves as the digital services librarian, is increasingly challenged to make it easier for users to find information from many heterogeneous information sources. Information is scattered throughout different software applications (i.e., library catalog, federated search engine, link…

The Hill cipher is the simplest example of a "block cipher," which takes a block of plaintext as input, and returns a block of ciphertext as output. Although it is insecure by modern standards, its simplicity means that it is well suited for the teaching of such concepts as encryption modes, and properties of cryptographic hash functions. Although…

Client speech in favor of change within motivational interviewing sessions has been linked to treatment outcomes, but a causal chain has not yet been demonstrated. Using a sequential behavioral coding system for client speech, the authors found that, at both the session and utterance levels, specific therapist behaviors predict client change talk.…

Longitudinal research designs involve data collection at multiple time points to measure change over time. Therefore, identification of the same respondents is essential at each time point so that data from the same respondents can be matched for comparison over time. Subject-generated identification codes permit an anonymous means to track…

The Information Age has been built, in part, on the belief that more information is always better. True to that sentiment, people have found ways to make a lot of information available to the masses--perhaps more than anyone ever imagined. The goal of the Semantic Web, often called Web 3.0, is for users to spend less time looking for information…

In this article, the authors have 2 aims. First, hierarchical, nonhierarchical, and nonstandard log-linear models are defined. Second, application scenarios are presented for nonhierarchical and nonstandard models, with illustrations of where these scenarios can occur. Parameters can be interpreted in regard to their formal meaning and in regard…

This article describes a procedure which has proven useful in facilitating narratives about experience of everyday family situations in order to provide insights into the inner world of children around five-seven years. The Windows to Attachment in Young Children (WAYC) consists of the procedure itself and scoring frameworks through which the…

In this essay, the authors chronicle the overhauling of their English department's rubric design, curriculum, and portfolio in order to emphasize a wider range of "real-world" writing. The authors share that in the process of their overhaul, they redefined their identity--how they thought of themselves and how they wanted to approach…

When students learn mathematics, they tend to understand and remember the mathematical processes that they find practical and relevant. It is not surprising then that "Principles and Standards for School Mathematics" (NCTM 2000) encourages teachers to help students discover the relevance of mathematics in their daily lives. To help young people…

In order to get the most from LibQUAL+[TM] qualitative data, libraries must organize and classify the comments of their patrons. The challenge is to do this effectively and efficiently. This article illustrates how researchers at Western Michigan University Libraries utilized ATLAS.ti 5.0 to organize, classify, and consolidate the LibQUAL+[TM]…

In May 2008, the first National Assessment Program for Literacy and Numeracy (NAPLAN) test was administered across Australia to determine the standard of literacy and numeracy achievement of Australia's students in Years 3, 5, 7 and 9. Some students did very well on the tests and some did not. This type of test can tell a great deal about…

Generally recognized as the standard work in its field, "Behavioral, Social, and Emotional Assessment of Children and Adolescents" provides a comprehensive foundation and guide for conducting conceptually sound, culturally responsive, and ecologically oriented assessments of student social and emotional behavior. It is aimed at graduate…

Many researchers and clinicians believe that the therapeutic relationship is essential in bringing about clinical change. Empirical research to support this contention is scarce in part due to the difficulty of specifying and measuring theoretically derived mechanisms of change and the important dimensions of the client-therapist relationship.…

The forms of words as they appear in text and speech are central to theories and models of lexical processing. Nonetheless, current methods for simulating their learning and representation fail to approach the scale and heterogeneity of real wordform lexicons. A connectionist architecture termed the "sequence encoder" is used to learn…

In order to get undergraduates interested in mathematics, it is necessary to motivate them, give them good reasons to spend time on a subject that requires hard work, and, if possible, involve them in undergraduate research. This article discusses how cryptography can be used for all these purposes. In particular, a special topics course on…
