The recent report, “Serum prolactin level in psoriasis”, is very interesting 1. Ghiasi et al. concluded that “it seems that while intracutaneous prolactin may contribute to the pathogenesis of psoriasis, the probable role of pituitary-produced circulating prolactin in the disease process needs further investigation .” There are some concerns on this report. First, although Ghiasi et al. have st...

Rangachari PK. Teaching undergraduates the process of peer review: learning by doing. Adv Physiol Educ 34: 137–144, 2010; doi:10.1152/advan.00071.2009.—An active approach allowed undergraduates in Health Sciences to learn the dynamics of peer review at first hand. A four-stage process was used. In stage 1, students formed self-selected groups to explore specific issues. In stage 2, each group p...

This paper presents the Navigation Maps Modeling approach (NMM), which provides platform independent models for characterizing navigation maps of web applications. The NMM approach is conceived to obtain a trade off between high and low-level design notations. As high-level design notations, NMM models permit architectural details that may hinder the overall understanding of the web application...

This paper discusses learning contents design from the viewpoint of knowledge level and symbol level. The purpose of study is to develop a foundation for share and reuse of IESs on a global platform. SCORM2004 is becoming de facto standard so we choice it as the basis of the platform. On the platform we aim to build an environment for authors to clarify pedagogical meaning of learning contents ...

The ability of listeners to detect level differences between two sinusoidal stimuli in a two-interval forced-choice procedure was measured as a function of duration and level in three conditions: (1) the pedestal was fixed in level and the stimuli in the two intervals had the same frequency of either 1 or 2 kHz (fixed-level condition); (2) the pedestal was roved in level over a 20-dB range from...

We study the impact of new information about food safety on subjects’ willingnessto-pay for food products, in an experimental setting. We elicit prices using either a second price auction or the Becker-DeGroot-Marschak procedure. There are three stages of bidding. In stage 1, subjects bid for products without any information. In stage 2, public information about health impact is provided. In st...
