Aristotle was the first philosopher to define the term thesis. The purpose of the dissertation is thus to outline the proofs of why the author disagrees with other philosophers or the general opinion. Structure[ edit ] A thesis or dissertation may be arranged as a thesis by publication or a monographwith or without appended papers, respectively, though many graduate programs allow candidates to submit a curated collection of published papers.

Please see the update to this blog! The best part about writing a dissertation is finding clever ways to procrastinate. I think a major deterrent that keeps people away from graduate school is the requirement to write a dissertation or thesis.

One often hears horror stories of the excessive page lengths that are expected.

A thesis for Distinction in Biology should be a presentation, written primarily for the non-specialist reader, of the significance, results and conclusions of a productive research project. A Ph.D., or Doctor of Philosophy, is among the highest of degree levels and takes years to earn. The exact length depends on how much time you must spend on your courses, exams, and dissertation. tchomptchomp PhD*, Developmental Biology 0 points 1 point 2 points 3 years ago There are two parts: an exit seminar and the actual defense. Exit seminars should be the length of .

A single chapter may be pages in length, whereas the same chapter published in the primary literature may only be 10 or so pages long in a journal. Any professor will tell you that page length is not a good indicator of the quality of your work.

Regardless, I feel that some general page length goal should be established prior to writing.

One could argue that it indicates absolutely nothing. My advisor once told me about a student in Chemistry that produced a dissertation that was less than five pages, and included nothing more than a molecular equation that illustrated the primary findings of the research.

Like any indicator, page length provides information that may or may not be useful. However, I guarantee that almost every graduate student has thought about an appropriate page length on at least one occasion during their education.

The University of Minnesota library system has been maintaining electronic dissertations since in their Digital Conservancy website. These digital archives represent an excellent opportunity for data mining.

Unfortunately, the code will not work unless you are signed in to the University of Minnesota library system. Obviously, this sample is not representative of all institutions or time periods, so extrapolation may be unwise. The code returns a list with two elements for each author.

This raw HTML is then further parsed using some of the base functions in R, such as grep and strsplit. The tricky part is to find the permanent URL for each student that contains the relevant information. The loop stops once all records are imported.

The important part is to identify the format of each URL so the code knows where to look and where to re-initiate each search. For example, each author has a permanent URL that has the basic form http: The permanent URL for each student is then accessed and parsed.

The important piece of information for each student takes the following form: University of Minnesota Ph. This chunk of text is then saved to the output object for additional parsing.

After the online data were obtained, the following code was used to identify page length, major, month of completion, year of completion, and advisor for each character string for each student.

The resulting text is converted to a data frame and some minor reworkings are applied to convert some vectors to numeric or factor values. Now the data are analyzed using the check. The data contained 2, records for students that completed their dissertations since The range was incredibly variable minimum of 21 pages, maximum ofbut most dissertations were around to pages.

Interestingly, a lot of students graduated in August just prior to the fall semester. As expected, spikes in defense dates were also observed in December and May at the ends of the fall and spring semesters.

The top four majors with the most dissertations on record were in descending order educational policy and administration, electrical engineering, educational psychology, and psychology. Not many differences are observed among the majors, although some exceptions are apparent.

Economics, mathematics, and biostatistics had the lowest median page lengths, whereas anthropology, history, and political science had the highest median page lengths. This distinction makes sense given the nature of the disciplines. The maximum number of students that completed their dissertations for a single advisor since was eight.

For those interested, the below code was used to create the plots.As many PhD candidates are wont to do, Beck took the pressure of readying for his defense and channeled it toward an incredibly interesting (if entirely thesis-unrelated) side project. PhD programs online or nearby.

A Ph.D., or Doctor of Philosophy, is among the highest of degree levels and takes years to earn. The exact length depends on how much time you must spend on your courses, exams, and dissertation. The importance is in the content and the originality of the Ph.d thesis and not in the number of pages.

However, depending on the area, the number of pages may vary from 25 to hundreds of pages. "The length of the 44 thesis conclusions ranged from 2 to 38 pages, averaging pages. There was a marked difference, however, between those in ST disciplines and those in HSS disciplines.
