Difference between "referee" and "reviewer"?

I've seen the terms "referee" and "reviewer" both used to describe a person who gives feedback to a paper in a journal submission. Are there differences between the two terms? Is one used in some situations where the other isn't?

What are the chances of getting into a PhD program in math after other pursuits in life?

I have a very unusual profile for a PhD program applicant. I worked a few years in business after college and have recently completed a J.D. I did not have much research experience in college except my honors thesis. My grades in math are solid but I did not take any grad level classes. After the many side distractions, I have decided that I would like to study math and do math research. I do love math and was quite good at it. I'm concerned that the admissions committee might view me trajectory as unfocused.

I would appreciate any feedback and suggestion as to how I can best remedy my situation.

Thank you so much for your help.

Tips on my future path (15 years from now)

I'll be able to finish my Computer Science degree next year, but I'm thinking of what are my options for my career and my education.

NOTE: My college education is not really top-notch (third world country), most of my knowledge is based on self-study from related knowledge on a courses.

I'm thinking of taking a Masters Degree (in Computer Science) 2-3 years after I graduate, hopefully that I already earned enough money to do that. Then proceed on my own research, probably related to artificial intelligence. Then take the route to be a professor, and if everything will be smooth, I'm aiming for a doctorate degree.

Is this the correct plan that I should take? My goal is to have a significant contribution to this field, as my country is not really well known in this field (the most famous one in my country, created a virus).

Any tips on what I should do/take first to achieve my goals? I'm also thinking of taking my graduate studies in other countries, since this field is not really good in this country (the computer science degree here is almost identical to Information Technology, maybe a bit harder on most cases but almost no distinction).

Best undergrad degree for neurology

when speaking with representatives from a few different college on the topic of an undergrad degree before applying to med school for neurology I got some pretty vague answers. They all told me generally the same thing, Get a major in one of the sciences (Literally that was how specific they were). So I'm seeking opinions on what some of the more helpful majors are for that field.

How to find DOI for article in JSTOR?

I have a link to an article on JSTOR. I can't see the DOI mentioned. Is there a standard way to find the DOI? Do all articles on JSTOR have an assigned DOI?

Struggling to find a foundation in mathematics worth 90 Ects points

I'm a 2:1 university graduate in computer science, and I'm thinking about doing postgraduate studies. The thing is that many of the degree schemes require at least 90 ECTS credits in mathematics as a requirement to enrolment in the course.

I don't have a mathematics A-levels, so I would need some foundation course that goes over the basics and bridges the gap into postgraduate study. I've done some searching but nothing has really turned up.

what are my options ?

How can I approach my professor when he is sending me indirect messages with another person?

After achieving my masters degree, i applied for a phd program at the same university i was graduated from. In Germany, a person has to find 2 advisors to be registered as a phd student and thats it for the begining.

I approached a professor whose area is related to my research.I told my intention and research idea to him and he said he would like to be my advisor but he officially cannot be the first advisor due to the number of students he already has. Instead, he suggested that he can be my second advisor and i should find another professor as my first advisor, in this way we can continue working anyway.

I decided to approach another professor (who is also a colleague of 2.advisor) and I asked him if he could be my first advisor and he accepted. We have exchanged more than 10 e-mails, talking about my proposal. When he came to my city, we met and everything looked fine. I continued to work on my proposal and sent him after a while. I needed to get a reference letter from him, as I am applying for potential scholarships. Some of these scholarships demand the reference letter to be sent directly by the professors. He has written the reference letter and wrote me an e-mail saying that he has sent the letter to the grant givers i asked him to send. I have asked him to send the letter also to me as a pdf, since i need to upload it personally as well. He has not send it to me and since weeks he is not replying my e-mails.

Instead, he has sent me an indirect message with a friend of mine (also a student of his), saying that I should work more on my proposal and it would be difficult to get a scholarship with such inaccurate proposal. He told her that I have been rushing to finish it and I should stop and reconsider my steps. He also added that, due to the inner conflicts he has with the faculty, he will be resigning in two years so maybe i should consider to find another first advisor as well.

I found this indirect communication unusual, disturbing and i must say, unprofessional. I decided to send him another e-mail, asking him if he can approve what I heard from my friend so that I can begin to search for another first advisor. Because if he officialy does not write it, i'm still registered as his student and it would be awkward to search for another one while I still have one. He is not replying to this e-mail as well. I have been applying for another scholarship meanwhile (only with one reference letter which is from my second advisor) and today i recieved a note from this scholarship, saying that my file has been taken under consideration but i should send the other reference letter as soon as possible.

My professor is literally blocking me from applying further. I have understood what he meant by taking more time to focus on my proposal but for now I need this reference letter from him. It just doesn't make sense that I cannot have the letter when it is already written for me. My question would be, shall I contact and ask my second advisor about his opinion on this situation or shall I take a step back and wait for my first advisor's conflicts to be cleared and hopefully he writes back to me?
