用烤箱做烧饼的方法:谁知到国外associate professor 和 assistant professor有什么区别？

Let's use lay terms to understand the differences. When we apply for a job, the position may be a temporary contract job for 6 months. It may be a permanent job forever, but we must pass the probation first.

Temporary position for professorship is an adjunct professorship. Sometimes, a full time well known professor from a famous university can go to another university to join a research program for a few months to a few years. Anyway, all adjunct professors are temporary.

An assistant professorship is an entry level position for new PhD graduates. He/she must work hard to produce enough research publications to obtain his/her tenure, like passing a probation.

An associate professor has passed his tenure (probation) and is a full time permanent staff, though his position is still junior.

A professor is a tenure permanent full time staff and is more senior by promotion.

第一个是副教授。
第二个是助理教授，级别高于讲师，低于副教授。
第三个也是副教授。
我估摸着第一种和第三种的区别在于语言或者学校的差异。
