of 174 respondents and acceptance of males in the nursing profession by multiple regression analysis has indicated that only two of the variables, namely, respondents' educational level and sex, significantly predict the attitudes toward male nurses (Laroche and Livneh, 1983).
I have always used by end of business which normally means by 5pm. I think that it depends on who you are sending the email to. If it is a superior you might want to reconsider and define an exact time deadline. If it is to a subordinate giving a general time frame like end of today or end of the day would be fine. share|improve this answer.
It's been asked and answered a gazillion times on College Confidential. A November 1 deadline means that the college wants your materials submitted on or before November 1. So if you submit at 11:59 p.m. on November 1, you meet the deadline. But you should be aware, many colleges have so many last-minute submissions that applicants crash the servers at colleges or at the Common Application. Some students have technical difficulties on their own end.
