The latent factor in a causal indicator model is no more than the latent factor of the factor part of the model. However, if the causal indicator variables are well-understood and help to improve the prediction of individuals' factor scores, they can help to interpret the meaning of the latent factor. Aguirre-Urreta, Rönkkö, and Marakas (2016)…

The slope of the z-transformed receiver-operating characteristic (zROC) in recognition memory experiments is usually less than 1, which has long been interpreted to mean that the variance of the target distribution is greater than the variance of the lure distribution. The greater variance of the target distribution could arise because the…

The sources of forgetting in working memory (WM) are a matter of intense debate: Is there a time-related decay of memory traces, or is forgetting uniquely due to representation-based interference? In a previous study, we claimed to have provided evidence supporting the temporal decay hypothesis (S. Portrat, P. Barrouillet, & V. Camos, 2008).…

Liberal arts universities are under mounting pressure to maintain their position of relevance in an increasingly technological and economically competitive world, while professional journalism is steadily losing ground to social media. This essay argues that a new partnership between journalism schools and the academic community would be…

E. Brandstatter, G. Gigerenzer, and R. Hertwig (2006) contended that their priority heuristic, a type of lexicographic semiorder model, is more accurate than cumulative prospect theory (CPT) or transfer of attention exchange (TAX) models in describing risky decisions. However, there are 4 problems with their argument. First, their heuristic is not…

This paper describes the current status of teacher supply and demand in both special and general education, presents examples of the kinds of data and analyses which comply with the Individuals with Disabilities Education Act, and discusses how educational policymaking might be affected by the mandate to project future personnel needs. (Author/DB)

Many problem-solving activities include mathematical principles but students do not use them during the design and experimentation phases before creating a prototype or product. Restricting the amount and/or type of materials available to students will require them to calculate and requisition the materials needed. (JOW)

The future occupational structure is projected to provide jobs for workers at all educational levels, but those with the most education and training will enjoy the best job opportunities. (Author)

People can use a variety of different strategies to perform tasks and these strategies all have two characteristics in common. First, they can be evaluated in comparison with either an absolute or a relative standard. Second, they can be used at varying levels of consistency. In the present article, the authors develop a general theory of task…

Rebuts the claims of Trusheim and Crouse, made in an earlier issue, that Scholastic Aptitude Test scores are no more effective predictors of college success than is high school class rank. Discusses inaccuracies in the data used by Trusheim and Crouse and points out errors in their analyses. (PGD)

Predicts that online searching in the 1990s will be characterized by end users discovering faster and easier ways to access information. Predicted trends that are discussed include databases designed for end users, pricing innovations, increased use of CD-ROM products, improved computer graphics, and the expansion of database products into the…

Offers an alternative to the U.S. Bureau of the Consensus population projection for 2050. Discusses alternative mortality, fertility, and immigration assumptions and projection methods that use a baseline scenario of no further gains against mortality. Description of the U.S. population under alternative scenarios include changes in structure and…

The labor force is expected to expand at an annual rate of 1.2 percent, a much slower pace than in 1976-88; fast-growing segments include Blacks, Hispanics, Asians, and other minority groups. (Author)

Providing researchers, especially those in the social sciences, with access to publicly collected microdata furthers research while advancing public policy goals in a democratic society. However, while technological improvements have eased remote access to these databases and enabled computer using researchers to perform sophisticated statistical…

Reviews key developments in information technologies, and describes the possible convergence of these developments in the creation of a new publishing and communication medium. The impact of this technology on the organization and role of libraries is discussed. (4 references) (CLB)
