Previous studies have examined the influence of femininity on disordered eating behavior in female undergraduates, but few studies have examined the relation between gender roles and disordered eating in male undergraduates. The present study examined whether gender roles relate to disordered eating behaviors the same way in male and female undergraduates. 512 undergraduates (58% female) at a l...

The detailed design of a robust and inexpensive optical trap system is presented. The system features high-sensitivity back focal plane position detection, mechanically controlled specimen stage movement, and fluorescence imaging to provide broad experimental applications. Three educational experimental modules are described to cover basic concepts in optical trapping and biophysics at a level ...

Medical, industrial, and basic research relies heavily on the use of viruses and vectors. Therefore, it is important that bioscience undergraduates learn the practicalities of handling viruses. Teaching practical virology in a student laboratory setup presents safety challenges, however. The aim of this article is to describe the design and implementation of a virology laboratory, with emphasis...

There are two ways to learn mathematics: to discover (research) and to rediscover. Inspiring exercises are used to guide students at all levels to rediscover the essential meaning of various individual pieces of mathematics. Their r^ ole has become all the more important at a time when Bourbakisation is the dominating fashion. While mathematics is decorated with a thick layer of cosmetics, such...

The calculation of the structure of white dwarf and neutron stars is a suitable topic for an undergraduate thesis or an advanced special topics or independent study course. The subject is rich in many different areas of physics, ranging from thermodynamics to quantum statistics to nuclear physics to special and general relativity. The computations for solving the coupled structure differential ...
