BACKGROUND & METHODS
The relationship between stress and breast cancer has been
examined in many epidemiological studies, the results of which have
yielded mixed results. One reason for these differences is the use
of different measures of stress. For example, death of a spouse or
close relative is a major acute stressor, whereas stress
experienced in daily life is more moderate and chronic in nature.
As these different types of stress likely have different
physiological and psychological impacts, the observed...

Students appear to rationalize their illicit behavior based on perceptions ofhow their teachers view cheating. Poor teachers are thought not to know or care whether students cheat, so cheating in their classes are OK. Good teachers, on the other hand, do care and are alert...
