microscope. While this chapter requires of its reader some knowledge of physics, it contains information which all electron microscopists should possess for a thorough understanding of the potentialities and limitations of this instrument. Three chapters follow on selected methods and techniques including preparation of metal specimens, mounting of particulate materials, and ultramicrotomy. The...

Hypochondriasis (HC) involves preoccupation with fears of having a serious medical illness based on the misinterpretation of benign bodily perturbations. Individuals with HC also perform behaviors such as checking and reassurance-seeking presumably to reduce health-related fears. Experimental behavioral analyses of HC symptoms, however, are lacking. In the present study, 27 patients with HC wer...

Angiogenesis is a fundamental process by which new blood vessels are formed. Progressive tumor growth necessitates the continuous induction of new capillary blood vessels which converge upon the tumor. Suppression of tumor growth can be accomplished with the use of antiangiogenesis agents. AGM-1470 is a potent angiogenesis inhibitor in vitro and in vivo. In mouse studies, AGM-1470 has suppresse...

In this paper we elicit preferences for discounting via experimental techniques. We then estimate a general speci…cation of discounting that nests exponential and hyperbolic discounting, as well as various forms of present bias, including quasihyperbolic discounting. The data strongly favor a speci…cation with a small present bias in the form of a …xed cost, of the order of $4 on average across...

The transition from telophase to the G I period of interphase includes the process of nucleolar reorganization in each of the daughter nuclei, and it has been demonstrated by the classic studies of Heitz (13) and McClintock (17) that only specific regions of particular chromosomes in each karyotype are involved in the formation of new nucleoli . On the other hand, a number of studies revealed t...

A method of data collection is presented that unites the efficiency of mass testing with the ease of instant electronic data collection that is typical of computer-based experiments run on individual participants. A wireless response system (WRS), originally designed as a teaching tool, is used to replicate three classic and robust effects from the memory literature (effects of false memory, le...

Students in psychology need to learn to design and analyze their own experiments. However, software that allows students to build experiments on their own has been limited in a variety of ways. The shipping of the first full release of the E-Prime system later this year will open up a new opportunity for addressing this problem. Because E-Prime promises to become the standard for building exper...

Technology-based interventions to promote health are expanding rapidly. Assessing the preliminary efficacy of these interventions can be achieved by employing single-case experiments (sometimes referred to as n-of-1 studies). Although single-case experiments are often misunderstood, they offer excellent solutions to address the challenges associated with testing new technology-based interventio...
