In fact, not even all professors are full professors. Many of them are assistant or associate professors or adjunct professors. So what do all of these different academic titles mean at American colleges and universities? Get ready for a short lecture, especially if you are thinking of a career in higher education. Professors usually need a doctoral degree. But sometimes a school will offer positions to people who have not yet received their doctorate. This person would be called an instructor until the degree has been completed. After that, the instructor could become an assistant professor. Assistant professors do not have tenure. Tenure means a permanent appointment. This goal of greater job security is harder to reach these days. Fewer teaching positions offer the chance for tenure. Teachers and researchers who are hired into positions that do offer it are said to be "on the tenure track." Assistant professor is the first job on this path. Assistant professors generally have five to seven years to gain tenure. During this time, other faculty members study the person's work. If tenure is denied, then the assistant professor usually has a year to find another job. Candidates for tenure may feel great pressure to get research published. "Publish or perish" is the traditional saying. An assistant professor who receives tenure becomes an associate professor. An associate professor may later be appointed a full professor. Assistant, associate and full professors perform many duties. They teach classes. They advise students. And they carry out research. They also serve on committees and take part in other activities. Other faculty members are not expected to do all these jobs. They are not on a tenure track. Instead, they might be in adjunct or visiting positions.

Should we allow the cinema to be constructed in the Havenswood Shopping Center? There is just one large area left to build on, and the theater would use up all of that space. Some people are excited at the idea of finally having our own movie theater. Others would rather travel ten miles to the nearest theater to keep our quiet town the way it is. They say it is enough to have Marvin's Movie Video Rentals. After all, Marvin's store keeps thousands of the latest videos. There are certainly benefits to renting videos. For one thing, you can plan your own schedule when it is convenient for you. You can relax on your sofa, and take a break whenever you need one. You can also talk to others without bothering any strangers seated nearby. In addition, it is a less expensive way to view a movie, especially if more than one person is watching the video. On the other hand, seeing a movie in a theater is an experience all its own. First, you can see the movie on a wide screen as the filmmaker intended. To be viewed on a television screen, a film must be changed in some way to make it smaller. One is the "pan-and-scan method, which involves removing some of the details in the picture. The other way, called "letterboxing, keeps the image the way it is on the big screen, with one annoying exception; because the big-screen style is wide, the same picture on a television screen must be long and narrow. Another problem is sound. The sound from a television cannot compare with the sound system in a theater. Your experience of a movie improves when you can clearly hear all of the sounds. Furthermore, at home, viewing companions often talk during a movie, which makes you miss out on what's happening in the film. Besides, having a movie theater will not mean that you can't still go to Marvin's! You will just have a choice that you didn't have before. Isn't it time for Havenswood residents like me to enjoy a little progress? Question: Who is the author probably? Options: A: An editor of a newspaper. B: The manager of the nearest theatre. C: The owner of Marvin's Movie Video Rentals. D: A concerned citizen in Havenswood.
