A thesis or dissertation is a document submitted in support of candidature for an academic degree or professional qualification presenting the author's research and findings. In some contexts, the word "thesis" or a cognate is used for part of a bachelor's or master's course, while "dissertation" is normally applied to a doctorate, while in other contexts, the reverse is true. The term graduate thesis is sometimes used to refer to both master's theses and doctoral dissertations.
The required complexity or quality of research of a thesis or dissertation can vary by country, university, or program, and the required minimum study period may thus vary significantly in duration.
The word "dissertation" can at times be used to describe a treatise without relation to obtaining an academic degree. The term "thesis" is also used to refer to the general claim of an essay or similar work.
The term "thesis" comes from the Greek θέσις, meaning "something put forth", and refers to an intellectual proposition. "Dissertation" comes from the Latin dissertātiō, meaning "discussion". Aristotle was the first philosopher to define the term thesis.
"A 'thesis' is a supposition of some eminent philosopher that conflicts with the general opinion...for to take notice when any ordinary person expresses views contrary to men's usual opinions would be silly".
For Aristotle, a thesis would therefore be a supposition that is stated in contradiction with general opinion or express disagreement with other philosophers (104b33-35). A supposition is a statement or opinion that may or may not be true depending on the evidence and/or proof that is offered (152b32). The purpose of the dissertation is thus to outline the proofs of why the author disagrees with other philosophers or the general opinion.
A thesis (or dissertation) may be arranged as a thesis by publication or a monograph, with or without appended papers, respectively, though many graduate programs allow candidates to submit a curated collection of published papers. An ordinary monograph has a title page, an abstract, a table of contents, comprising the various chapters (e.g., introduction, literature review, methodology, results, discussion), and a bibliography or (more usually) a references section. They differ in their structure in accordance with the many different areas of study (arts, humanities, social sciences, technology, sciences, etc.) and the differences between them. In a thesis by publication, the chapters constitute an introductory and comprehensive review of the appended published and unpublished article documents.
Dissertations normally report on a research project or study, or an extended analysis of a topic. The structure of a thesis or dissertation explains the purpose, the previous research literature impinging on the topic of the study, the methods used, and the findings of the project. Most world universities use a multiple chapter format : a) an introduction, which introduces the research topic, the methodology, as well as its scope and significance; b) a literature review, reviewing relevant literature and showing how this has informed the research issue; c) a methodology chapter, explaining how the research has been designed and why the research methods/population/data collection and analysis being used have been chosen; d) a findings chapter, outlining the findings of the research itself; e) an analysis and discussion chapter, analysing the findings and discussing them in the context of the literature review (this chapter is often divided into two—analysis and discussion); f) a conclusion.
Degree-awarding institutions often define their own house style that candidates have to follow when preparing a thesis document. In addition to institution-specific house styles, there exist a number of field-specific, national, and international standards and recommendations for the presentation of theses, for instance ISO 7144. Other applicable international standards include ISO 2145 on section numbers, ISO 690 on bibliographic references, and ISO 31 on quantities or units.
Some older house styles specify that front matter (title page, abstract, table of content, etc.) must use a separate page number sequence from the main text, using Roman numerals. The relevant international standard and many newer style guides recognize that this book design practice can cause confusion where electronic document viewers number all pages of a document continuously from the first page, independent of any printed page numbers. They, therefore, avoid the traditional separate number sequence for front matter and require a single sequence of Arabic numerals starting with 1 for the first printed page (the recto of the title page).
Presentation requirements, including pagination, layout, type and color of paper, use of acid-free paper (where a copy of the dissertation will become a permanent part of the library collection), paper size, order of components, and citation style, will be checked page by page by the accepting officer before the thesis is accepted and a receipt is issued.
However, strict standards are not always required. Most Italian universities, for example, have only general requirements on the character size and the page formatting, and leave much freedom for the actual typographic details.
A thesis or dissertation committee is a committee that supervises a student's dissertation. In the US, these committees usually consist of a primary supervisor or advisor and two or more committee members, who supervise the progress of the dissertation and may also act as the examining committee, or jury, at the oral examination of the thesis (see below).
At most universities, the committee is chosen by the student in conjunction with his or her primary adviser, usually after completion of the comprehensive examinations or prospectus meeting, and may consist of members of the comps committee. The committee members are doctors in their field (whether a PhD or other designation) and have the task of reading the dissertation, making suggestions for changes and improvements, and sitting in on the defense. Sometimes, at least one member of the committee must be a professor in a department that is different from that of the student.
In the Latin American docta, the academic dissertation can be referred to as different stages inside the academic program that the student is seeking to achieve into a recognized Argentine University, in all the cases the students must develop original contribution in the chosen fields by means of several paper work and essays that comprehend the body of the thesis. Correspondingly to the academic degree, the last phase of an academic thesis is called in Spanish a defensa de grado, defensa magistral or defensa doctoral in cases in which the university candidate is finalizing his or her licentiate, master's, or PhD program. According to a committee resolution, the dissertation can be approved or rejected by an academic committee consisting of the thesis director, the thesis coordinator, and at least one evaluator from another recognized university in which the student is pursuing his or her academic program. All the dissertation referees must already have achieved at least the academic degree that the candidate is trying to reach.
At English-speaking Canadian universities, writings presented in fulfillment of undergraduate coursework requirements are normally called papers, term papers or essays. A longer paper or essay presented for completion of a 4-year bachelor's degree is sometimes called a major paper. High-quality research papers presented as the empirical study of a "postgraduate" consecutive bachelor with Honours or Baccalaureatus Cum Honore degree are called thesis (Honours Seminar Thesis). Major papers presented as the final project for a master's degree are normally called thesis; and major papers presenting the student's research towards a doctoral degree are called theses or dissertations.
At Canadian universities under the French influenced system, students may have a choice between presenting a "mémoire"', which is a shorter synthetic work (roughly 75 pages) and a thèse which is one hundred pages or more. A synthetic monograph associated with doctoral work is referred to as a "thèse". See also compilation thesis. Either work can be awarded a "mention d'honneur" (excellence) as a result of the decision by the examination committee, although these are rare.
A typical undergraduate paper or essay might be forty pages. Master's theses are approximately one hundred pages. PhD theses are usually over two hundred pages. This may vary greatly by discipline, program, college, or university. However, normally the required minimum study period is primarily depending on the complexity or quality of research requirements.
Theses Canada acquires and preserves a comprehensive collection of Canadian theses at Library and Archives Canada' (LAC) through a partnership with Canadian universities who participate in the program.
At most university faculties in Croatia, a degree is obtained by defending a thesis after having passed all the classes specified in the degree programme. In the Bologna system, the bachelor's thesis, called završni rad (literally "final work" or "concluding work") is defended after 3 years of study and is about 30 pages long. Most students with bachelor's degrees continue onto master's programmes which end with a master's thesis called diplomski rad (literally "diploma work" or "graduate work"). The term dissertation is used for a doctoral degree paper (doktorska disertacija).
In the Czech Republic, higher education is completed by passing all classes remaining to the educational compendium for given degree and defending a thesis. For bachelors programme the thesis is called bakalářská práce (bachelor's thesis), for master's degrees and also doctor of medicine or dentistry degrees it is the diplomová práce (master's thesis), and for Philosophiae doctor (PhD.) degree it is dissertation dizertační práce. Thesis for so called Higher-Professional School (Vyšší odborná škola, VOŠ) is called absolventská práce.
The following types of thesis are used in Finland (names in Finnish/Swedish):
In France, the academic dissertation or thesis is called a thèse and it is reserved for the final work of doctoral candidates. The minimum page length is generally (and not formally) 100 pages (or about 400,000 characters), but is usually several times longer (except for technical theses and for "exact sciences" such as physics and maths).
To complete a master's degree in research, a student is required to write a mémoire, the French equivalent of a master's thesis in other higher education systems.
The word dissertation in French is reserved for shorter (1,000–2,000 words), more generic academic treatises.
The defense is called a soutenance.
In Germany, an academic thesis is called Abschlussarbeit or, more specifically, the basic name of the degree complemented by -arbeit (rough translation: -work; e.g., Diplomarbeit, Masterarbeit, Doktorarbeit). For bachelor's and master's degrees, the name can alternatively be complemented by -thesis instead (e.g., Bachelorthesis).
Length is often given in page count and depends upon departments, faculties, and fields of study. A bachelor's thesis is often 40–60 pages long, a diploma thesis and a master's thesis usually 60–100. The required submission for a doctorate is called a Dissertation or Doktorarbeit. The submission for a Habilitation, which is an academic qualification, not an academic degree, is called Habilitationsschrift, not Habilitationsarbeit. PhD by publication is becoming increasingly common in many fields of study.
A doctoral degree is often earned with multiple levels of a Latin honors remark for the thesis ranging from summa cum laude (best) to rite (duly). A thesis can also be rejected with a Latin remark (non-rite, non-sufficit or worst as sub omni canone). Bachelor's and master's theses receive numerical grades from 1.0 (best) to 5.0 (failed).
In India the thesis defense is called a viva voce (Latin for "by live voice") examination (viva in short). Involved in the viva are two examiners and the candidate. One examiner is an academic from the candidate's own university department (but not one of the candidate's supervisors) and the other is an external examiner from a different university.
In India, PG Qualifications such as MSc Physics accompanies submission of dissertation in Part I and submission of a Project (a working model of an innovation) in Part II. Engineering qualifications such as BTech, B.E., MTech or M.E. also involves submission of dissertation. In all the cases, the dissertation can be extended for summer internship at certain research and development organizations or also as PhD synopsis.
In Indonesia, the term thesis is used specifically to refer to master's theses. The undergraduate thesis is called skripsi, while the doctoral dissertation is called disertasi. In general, those three terms are usually called as tugas akhir (final assignment), which is mandatory for the completion of a degree. Undergraduate students usually begin to write their final assignment in their third, fourth or fifth enrollment year, depends on the requirements of their respective disciplines and universities. In some universities, students are required to write a proposal skripsi or proposal tesis (thesis proposal) before they could write their final assignment. If the thesis proposal is considered to fulfill the qualification by the academic examiners, students then may proceed to write their final assignment.
In Iran, usually students are required to present a thesis in their master's degree and a dissertation in their Doctorate degree, both of which requiring the students to defend their research before a committee and gaining their approval. Most of the norms and rules of writing a thesis or a dissertation are influenced by the French higher education system.
In Italy there are normally three types of thesis. In order of complexity: one for the Laurea (equivalent to the UK Bachelor's Degree), another one for the Laurea Magistrale (equivalent to the UK Master's Degree) and then a thesis to complete the Dottorato di Ricerca (PhD). Thesis requirements vary greatly between degrees and disciplines, ranging from as low as 3–4 ECTS credits to more than 30. Thesis work is mandatory for the completion of a degree.
Malaysian universities often follow the British model for dissertations and degrees. However, a few universities follow the United States model for theses and dissertations. Some public universities have both British and US style PhD programs. Branch campuses of British, Australian and Middle East universities in Malaysia use the respective models of the home campuses.
In Pakistan, at undergraduate level the thesis is usually called final year project, as it is completed in the senior year of the degree, the name project usually implies that the work carried out is less extensive than a thesis and bears lesser credit hours too. The undergraduate level project is presented through an elaborate written report and a presentation to the advisor, a board of faculty members and students. At graduate level however, i.e. in MS, some universities allow students to accomplish a project of 6 credits or a thesis of 9 credits, at least one publication is normally considered enough for the awarding of the degree with project and is considered mandatory for the awarding of a degree with thesis. A written report and a public thesis defense is mandatory, in the presence of a board of senior researchers, consisting of members from an outside organization or a university. A PhD candidate is supposed to accomplish extensive research work to fulfill the dissertation requirements with international publications being a mandatory requirement. The defense of the research work is done publicly.
In the Philippines, an academic thesis is named by the degree, such as bachelor/undergraduate thesis or masteral thesis. However, in Philippine English, the term doctorate is typically replaced with doctoral (as in the case of "doctoral dissertation"), though in official documentation the former is still used. The terms thesis and dissertation are commonly used interchangeably in everyday language yet it generally understood that a thesis refers to bachelor/undergraduate and master academic work while a dissertation is named for doctorate work.
The Philippine system is influenced by American collegiate system, in that it requires a research project to be submitted before being allowed to write a thesis. This project is mostly given as a prerequisite writing course to the actual thesis and is accomplished in the term period before; supervision is provided by one professor assigned to a class. This project is later to be presented in front of an academic panel, often the entire faculty of an academic department, with their recommendations contributing to the acceptance, revision, or rejection of the initial topic. In addition, the presentation of the research project will help the candidate choose their primary thesis adviser.
An undergraduate thesis is completed in the final year of the degree alongside existing seminar (lecture) or laboratory courses, and is often divided into two presentations: proposal and thesis presentations (though this varies across universities), whereas a master thesis or doctorate dissertation is accomplished in the last term alone and is defended once. In most universities, a thesis is required for the bestowment of a degree to a candidate alongside a number of units earned throughout their academic period of stay, though for practice and skills-based degrees a practicum and a written report can be achieved instead. The examination board often consists of 3 to 5 examiners, often professors in a university (with a Masters or PhD degree) depending on the university's examination rules. Required word length, complexity, and contribution to scholarship varies widely across universities in the country.
In Poland, a bachelor's degree usually requires a praca licencjacka (bachelor's thesis) or the similar level degree in engineering requires a praca inżynierska (engineer's thesis/bachelor's thesis), the master's degree requires a praca magisterska (master's thesis). The academic dissertation for a PhD is called a dysertacja or praca doktorska. The submission for the Habilitation is called praca habilitacyjna" or dysertacja habilitacyjna". Thus the term dysertacja is reserved for PhD and Habilitation degrees. All the theses need to be "defended" by the author during a special examination for the given degree. Examinations for PhD and Habilitation degrees are public.
In Portugal and Brazil, a dissertation (dissertação) is required for completion of a master. The defense is done in a public presentation in which teachers, students, and the general public can participate. For the PhD, a thesis (tese) is presented for defense in a public exam. The exam typically extends over 3 hours. The examination board typically involves 5 to 6 scholars (including the advisor) or other experts with a PhD degree (generally at least half of them must be external to the university where the candidate defends the thesis, but it may depend on the University). Each university / faculty defines the length of these documents, and it can vary also in respect to the domains (a thesis in fields like philosophy, history, geography, etc., usually has more pages than a thesis in mathematics, computer science, statistics, etc.) but typical numbers of pages are around 60–80 for MSc and 150–250 for PhD.
In Brazil the Undergraduate Thesis is called TCC or Trabalho de Conclusão de Curso (Course Conclusion Work).
In Russia, Kazakhstan, Belarus, and Ukraine an academic dissertation or thesis is called what can be literally translated as a "master's degree work" (thesis), whereas the word dissertation is reserved for doctoral theses (Candidate of Sciences). To complete a master's degree, a student is required to write a thesis and to then defend the work publicly. The length of this manuscript usually is given in page count and depends upon educational institution, its departments, faculties, and fields of study
At universities in Slovenia, an academic thesis called diploma thesis is a prerequisite for completing undergraduate studies. The thesis used to be 40–60 pages long, but has been reduced to 20–30 pages in new Bologna process programmes. To complete Master's studies, a candidate must write magistrsko delo (Master's thesis) that is longer and more detailed than the undergraduate thesis. The required submission for the doctorate is called doktorska disertacija (doctoral dissertation). In pre Bologna programmes students were able to skip the preparation and presentation of a Master's thesis and continue straightforward towards doctorate.
In Slovakia, higher education is completed by defending a thesis, which is called bachelor's thesis "bakalárska práca" for bachelors programme, master's thesis or "diplomová práca" for master's degrees, and also doctor of medicine or dentistry degrees and dissertation "dizertačná práca" for Philosophiae doctor (PhD.) degree.
In Sweden, there are different types of theses. Practices and definitions vary between fields but commonly include the C thesis/Bachelor thesis, which corresponds to 15 HP or 10 weeks of independent studies, D thesis/'/Magister/one year master's thesis, which corresponds to 15 HP or 10 weeks of independent studies and E Thesis/two-year master's thesis, which corresponds to 30 HP or 20 weeks of independent studies. The undergraduate theses are called uppsats, sometimes examensarbete, especially at technical programmes.
After that there are two types of post graduate theses, licentiate thesis and PhD dissertation. A licentiate degree is approximately "half a PhD" in terms of size and scope of the thesis. Swedish PhD studies should in theory last for four years, including course work and thesis work, but as many PhD students also teach, the PhD often takes longer to complete. The thesis can be written as a monograph or as a compilation thesis, where the introductory chapters are called kappa, literally coat.
Outside the academic community, the terms thesis and dissertation are interchangeable. At universities in the United Kingdom, the term thesis is usually associated with PhD/EngD (doctoral) and research master's degrees, while dissertation is the more common term for a substantial project submitted as part of a taught master's degree or an undergraduate degree (e.g. BA, BSc, BMus, BEd, BEng etc.).
Thesis word lengths may differ by faculty/department and are set by individual universities.
A wide range of supervisory arrangements can be found in the British academy, from single supervisors (more usual for undergraduate and Masters level work) to supervisory teams of up to three supervisors. In teams, there will often be a Director of Studies, usually someone with broader experience (perhaps having passed some threshold of successful supervisions). The Director may be involved with regular supervision along with the other supervisors, or may have more of an oversight role, with the other supervisors taking on the more day-to-day responsibilities of supervision.
In some U.S. doctoral programs, the "dissertation" can take up the major part of the student's total time spent (along with two or three years of classes) and may take years of full-time work to complete. At most universities, dissertation is the term for the required submission for the doctorate, and thesis refers only to the master's degree requirement.
Thesis is also used to describe a cumulative project for a bachelor's degree and is more common at selective colleges and universities, or for those seeking admittance to graduate school or to obtain an honors academic designation. These projects are called "senior projects" or "senior theses"; they are generally done in the senior year near graduation after having completed other courses, the independent study period, and the internship or student teaching period (the completion of most of the requirements before the writing of the paper ensures adequate knowledge and aptitude for the challenge). Unlike a dissertation or master's thesis, they are not as long and they do not require a novel contribution to knowledge or even a very narrow focus on a set subtopic. Like them, they can be lengthy and require months of work, they require supervision by at least one professor adviser, they must be focused on a certain area of knowledge, and they must use an appreciable amount of scholarly citations. They may or may not be defended before a committee but usually are not; there is generally no preceding examination before the writing of the paper, except for at very few colleges. Because of the nature of the graduate thesis or dissertation having to be more narrow and more novel, the result of original research, these usually have a smaller proportion of the work that is cited from other sources, though the fact that they are lengthier may mean they still have total citations.
Specific undergraduate courses, especially writing-intensive courses or courses taken by upperclassmen, may also require one or more extensive written assignments referred to variously as theses, essays, or papers. Increasingly, high schools are requiring students to complete a senior project or senior thesis on a chosen topic during the final year as a prerequisite for graduation. The extended essay component of the International Baccalaureate Diploma Programme, offered in a growing number of American high schools, is another example of this trend.
Generally speaking, a dissertation is judged as to whether or not it makes an original and unique contribution to scholarship. Lesser projects (a master's thesis, for example) are judged by whether or not they demonstrate mastery of available scholarship in the presentation of an idea.
The required complexity or quality of research of a thesis may vary significantly among universities or programs.
One of the requirements for certain advanced degrees is often an oral examination (called a viva voce examination or just viva in the UK and certain other English-speaking countries). This examination normally occurs after the dissertation is finished but before it is submitted to the university, and may comprise a presentation (often public) by the student and questions posed by an examining committee or jury. In North America, an initial oral examination in the field of specialization may take place just before the student settles down to work on the dissertation. An additional oral exam may take place after the dissertation is completed and is known as a thesis or dissertation "defense", which at some universities may be a mere formality and at others may result in the student being required to make significant revisions.
The result of the examination may be given immediately following deliberation by the examiners (in which case the candidate may immediately be considered to have received his or her degree), or at a later date, in which case the examiners may prepare a defense report that is forwarded to a Board or Committee of Postgraduate Studies, which then officially recommends the candidate for the degree.
Potential decisions (or "verdicts") include:
At most North American institutions the latter two verdicts are extremely rare, for two reasons. First, to obtain the status of doctoral candidates, graduate students typically write a qualifying examination or comprehensive examination, which often includes an oral defense. Students who pass the qualifying examination are deemed capable of completing scholarly work independently and are allowed to proceed with working on a dissertation. Second, since the thesis supervisor (and the other members of the advisory committee) will normally have reviewed the thesis extensively before recommending the student proceed to the defense, such an outcome would be regarded as a major failure not only on the part of the candidate but also by the candidate's supervisor (who should have recognized the substandard quality of the dissertation long before the defense was allowed to take place). It is also fairly rare for a thesis to be accepted without any revisions; the most common outcome of a defense is for the examiners to specify minor revisions (which the candidate typically completes in a few days or weeks).
At universities on the British pattern it is not uncommon for theses at the viva stage to be subject to major revisions in which a substantial rewrite is required, sometimes followed by a new viva. Very rarely, the thesis may be awarded the lesser degree of M.Phil (Master of Philosophy) instead, preventing the candidate from resubmitting the thesis.
In Australia, doctoral theses are usually examined by three examiners although some, like the Australian Catholic University and the University of New South Wales, have shifted to using only two examiners; without a live defense except in extremely rare exceptions. In the case of a master's degree by research the thesis is usually examined by only two examiners. Typically one of these examiners will be from within the candidate's own department; the other(s) will usually be from other universities and often from overseas. Following submission of the thesis, copies are sent by mail to examiners and then reports sent back to the institution.
Similar to a master's degree by research thesis, a thesis for the research component of a master's degree by coursework is also usually examined by two examiners, one from the candidate's department and one from another university. For an Honours year, which is a fourth year in addition to the usual three-year bachelor's degree, the thesis is also examined by two examiners, though both are usually from the candidate's own department. Honours and Master's theses sometimes require an oral defense before they are accepted.
In Germany, a thesis is usually examined with an oral examination. This applies to almost all Diplom, Magister, master's and doctoral degrees as well as to most bachelor's degrees. However, a process that allows for revisions of the thesis is usually only implemented for doctoral degrees.
There are several different kinds of oral examinations used in practice. The Disputation, also called Verteidigung ("defense"), is usually public (at least to members of the university) and is focused on the topic of the thesis. In contrast, the Rigorosum is not held in public and also encompasses fields in addition to the topic of the thesis. The Rigorosum is only common for doctoral degrees. Another term for an oral examination is Kolloquium, which generally refers to a usually public scientific discussion and is often used synonymously with Verteidigung.
In each case, what exactly is expected differs between universities and between faculties. Some universities also demand a combination of several of these forms.
Like the British model, the PHD or MPhil student is required to submit their theses or dissertation for examination by two or three examiners. The first examiner is from the university concerned, the second examiner is from another local university and the third examiner is from a suitable foreign university (usually from Commonwealth countries). The choice of examiners must be approved by the university senate. In some public universities, a PhD or MPhil candidate may also have to show a number publications in peer reviewed academic journals as part of the requirement. An oral viva is conducted after the examiners have submitted their reports to the university. The oral viva session is attended by the Oral Viva chairman, a rapporteur with a PhD qualification, the first examiner, the second examiner and sometimes the third examiner.
Branch campuses of British, Australian and Middle East universities in Malaysia use the respective models of the home campuses to examine their PhD or MPhil candidates.
In the Philippines, a thesis is followed by an oral defense. In most universities, this applies to all bachelor, master, and doctorate degrees. However, the oral defense is held in once per semester (usually in the middle or by the end) with a presentation of revisions (so-called "plenary presentation") at the end of each semester. The oral defense is typically not held in public for bachelor and master oral defenses, however a colloquium is held for doctorate degrees.
In Portugal, a thesis is examined with an oral defense, which includes an initial presentation by the candidate followed by an extensive questioning/answering period. Typical duration for the total exam is 1 hour 30 minutes for the MSc and 3 hours for the PhD.
The examining committee normally consists of the thesis committee, usually a given number of professors mainly from the student's university plus his or her primary supervisor, an external examiner (someone not otherwise connected to the university), and a chair person. Each committee member will have been given a completed copy of the dissertation prior to the defense, and will come prepared to ask questions about the thesis itself and the subject matter. In many schools, master's thesis defenses are restricted to the examinee and the examiners, but doctoral defenses are open to the public.
The typical format will see the candidate giving a short (20–40-minute) presentation of his or her research, followed by one to two hours of questions.
At some U.S. institutions, a longer public lecture (known as a "thesis talk" or "thesis seminar") by the candidate will accompany the defense itself, in which case only the candidate, the examiners, and other members of the faculty may attend the actual defense.
A student in Ukraine or Russia has to complete a thesis and then defend it in front of their department. Sometimes the defense meeting is made up of the learning institute's professionals and sometimes the students peers are allowed to view or join in. After the presentation and defense of the thesis, the final conclusion of the department should be that none of them have reservations on the content and quality of the thesis.
A conclusion on the thesis has to be approved by the rector of the educational institute. This conclusion (final grade so to speak) of the thesis can be defended/argued not only at the thesis council, but also in any other thesis council of Russia or Ukraine.
The Diploma de estudios avanzados (DEA) can last two years and candidates must complete coursework and demonstrate their ability to research the specific topics they have studied. After completing this part of the PhD, students begin a dissertation on a set topic. The dissertation must reach a minimum length depending on the subject and it is valued more highly if it contains field research. Once candidates have finished their written dissertations, they must present them before a committee. Following this presentation, the examiners will ask questions.
In Hong Kong, Ireland and the United Kingdom, the thesis defense is called a viva voce (Latin for "by live voice") examination (viva for short). A typical viva lasts for approximately 3 hours, though there is no formal time limit. Involved in the viva are two examiners and the candidate. Usually, one examiner is an academic from the candidate's own university department (but not one of the candidate's supervisors) and the other is an external examiner from a different university. Increasingly, the examination may involve a third academic, the 'chair'; this person, from the candidate's institution, acts as an impartial observer with oversight of the examination process to ensure that the examination is fair. The 'chair' does not ask academic questions of the candidate.
In the United Kingdom, there are only two or at most three examiners, and in many universities the examination is held in private. The candidate's primary supervisor is not permitted to ask or answer questions during the viva, and their presence is not necessary. However, some universities permit members of the faculty or the university to attend. At the University of Oxford, for instance, any member of the University may attend a DPhil viva (the University's regulations require that details of the examination and its time and place be published formally in advance) provided he or she attends in full academic dress.
A submission of the thesis is the last formal requirement for most students after the defense. By the final deadline, the student must submit a complete copy of the thesis to the appropriate body within the accepting institution, along with the appropriate forms, bearing the signatures of the primary supervisor, the examiners, and in some cases, the head of the student's department. Other required forms may include library authorizations (giving the university library permission to make the thesis available as part of its collection) and copyright permissions (in the event that the student has incorporated copyrighted materials in the thesis). Many large scientific publishing houses (e.g. Taylor & Francis, Elsevier) use copyright agreements that allow the authors to incorporate their published articles into dissertations without separate authorization.
Failure to submit the thesis by the deadline may result in graduation (and granting of the degree) being delayed. At most U.S. institutions, there will also be various fees (for binding, microfilming, copyright registration, and the like), which must be paid before the degree will be granted.
Once all the paperwork is in order, copies of the thesis may be made available in one or more university libraries. Specialist abstracting services exist to publicize the content of these beyond the institutions in which they are produced. Many institutions now insist on submission of digitized as well as printed copies of theses; the digitized versions of successful theses are often made available online.
In computability theory, the Church–Turing thesis (also known as computability thesis, the Turing–Church thesis, the Church–Turing conjecture, Church's thesis, Church's conjecture, and Turing's thesis) is a hypothesis about the nature of computable functions. It states that a function on the natural numbers can be calculated by an effective method, if and only if it is computable by a Turing machine. The thesis is named after American mathematician Alonzo Church and the British mathematician Alan Turing. Before the precise definition of computable function, mathematicians often used the informal term effectively calculable to describe functions that are computable by paper-and-pencil methods. In the 1930s, several independent attempts were made to formalize the notion of computability:
In 1933, Kurt Gödel, with Jacques Herbrand, created a formal definition of a class called general recursive functions. The class of general recursive functions is the smallest class of functions (possibly with more than one argument) which includes all constant functions, projections, the successor function, and which is closed under function composition, recursion, and minimization.
In 1936, Alonzo Church created a method for defining functions called the λ-calculus. Within λ-calculus, he defined an encoding of the natural numbers called the Church numerals. A function on the natural numbers is called λ-computable if the corresponding function on the Church numerals can be represented by a term of the λ-calculus.
Also in 1936, before learning of Church's work, Alan Turing created a theoretical model for machines, now called Turing machines, that could carry out calculations from inputs by manipulating symbols on a tape. Given a suitable encoding of the natural numbers as sequences of symbols, a function on the natural numbers is called Turing computable if some Turing machine computes the corresponding function on encoded natural numbers.Church and Turing proved that these three formally defined classes of computable functions coincide: a function is λ-computable if and only if it is Turing computable if and only if it is general recursive. This has led mathematicians and computer scientists to believe that the concept of computability is accurately characterized by these three equivalent processes. Other formal attempts to characterize computability have subsequently strengthened this belief (see below).
On the other hand, the Church–Turing thesis states that the above three formally-defined classes of computable functions coincide with the informal notion of an effectively calculable function. Since, as an informal notion, the concept of effective calculability does not have a formal definition, the thesis, although it has near-universal acceptance, cannot be formally proven.
Since its inception, variations on the original thesis have arisen, including statements about what can physically be realized by a computer in our universe (physical Church-Turing thesis) and what can be efficiently computed (Church–Turing thesis (complexity theory)). These variations are not due to Church or Turing, but arise from later work in complexity theory and digital physics. The thesis also has implications for the philosophy of mind (see below).Dialectic
Dialectic or dialectics (Greek: διαλεκτική, dialektikḗ; related to dialogue), also known as the dialectical method, is at base a discourse between two or more people holding different points of view about a subject but wishing to establish the truth through reasoned arguments. Dialectic resembles debate, but the concept excludes subjective elements such as emotional appeal and the modern pejorative sense of rhetoric. Dialectic may be contrasted with the didactic method, wherein one side of the conversation teaches the other. Dialectic is alternatively known as minor logic, as opposed to major logic or critique.
Within Hegelianism, the word dialectic has the specialised meaning of a contradiction between ideas that serves as the determining factor in their relationship. Dialectic comprises three stages of development: first, a thesis or statement of an idea, which gives rise to a second step, a reaction or antithesis that contradicts or negates the thesis, and third, the synthesis, a statement through which the differences between the two points are resolved. Dialectical materialism, a theory or set of theories produced mainly by Karl Marx and Friedrich Engels, adapted the Hegelian dialectic into arguments regarding traditional materialism.
Dialectic tends to imply a process of evolution and so does not naturally fit within formal logic (see logic and dialectic). This process is particularly marked in Hegelian dialectic and even more so in Marxist dialectic which may rely on the evolution of ideas over longer time periods in the real world; dialectical logic attempts to address this.Doctor of Medicine
A Doctor of Medicine (M.D. from Latin Medicinae Doctor) is a medical degree, the meaning of which varies between different jurisdictions. In the United States, Canada and some other countries, the MD denotes a professional graduate degree awarded upon graduation from medical school. In the United Kingdom, Ireland and other countries, the MD is a research doctorate, higher doctorate, honorary doctorate or applied clinical degree restricted to those who already hold a professional degree in medicine; in those countries, the equivalent professional degree is typically titled Bachelor of Medicine, Bachelor of Surgery (MBBS).Doctor of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin philosophiae doctor or doctor philosophiae) is the highest university degree that is conferred after a course of study by universities in most English-speaking countries. PhDs are awarded for programs across the whole breadth of academic fields. As an earned research degree, those studying for a PhD are usually required to produce original research that expands the boundaries of knowledge, normally in the form of a thesis or dissertation, and defend their work against experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields.
Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title Doctor (often abbreviated "Dr" or "Dr.") or, in non-English-speaking countries, variants such as "Dr. phil." with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at universities or work in academic, educational, or research fields are usually addressed by this title "professionally and socially in a salutation or conversation." Alternatively, holders may use post-nominal letters such as "Ph.D.", "PhD", or "DPhil" (depending on the awarding institution). It is, however, considered incorrect to use both the title and post-nominals at the same time.The specific requirements to earn a PhD degree vary considerably according to the country, institution, and time period, from entry-level research degrees to higher doctorates. During the studies that lead to the degree, the student is called a doctoral student or PhD student; a student who has completed all of their coursework and comprehensive examinations and is working on their thesis/dissertation is sometimes known as a doctoral candidate or PhD candidate (see: all but dissertation). A student attaining this level may be granted a Candidate of Philosophy degree at some institutions, or may be granted a master's degree en route to the doctoral degree. Sometimes this status is also colloquially known as "Ph.D. ABD", meaning "All But Dissertation".A PhD candidate must submit a project, thesis or dissertation often consisting of a body of original academic research, which is in principle worthy of publication in a peer-reviewed journal. In many countries, a candidate must defend this work before a panel of expert examiners appointed by the university. Universities sometimes award other types of doctorate besides the PhD, such as the Doctor of Musical Arts (D.M.A.) for music performers and the Doctor of Education (Ed.D.) for professional educators. In 2005 the European Universities Association defined the "Salzburg Principles", 10 basic principles for third-cycle degrees (doctorates) within the Bologna Process. These were followed in 2016 by the "Florence Principles", seven basic principles for doctorates in the arts laid out by the European League of Institutes of the Arts, which have been endorsed by the European Association of Conservatoires, the International Association of Film and Television Schools, the International Association of Universities and Colleges of Art, Design and Media, and the Society for Artistic Research.In the context of the Doctor of Philosophy and other similarly titled degrees, the term "philosophy" does not refer to the field or academic discipline of philosophy, but is used in a broader sense in accordance with its original Greek meaning, which is "love of wisdom". In most of Europe, all fields (history, philosophy, social sciences, mathematics, and natural philosophy/sciences) other than theology, law, and medicine (the so-called professional, vocational, or technical curriculum) were traditionally known as philosophy, and in Germany and elsewhere in Europe the basic faculty of liberal arts was known as the "faculty of philosophy".Doctor of Science
For the degree granted by Soviet institutions, see Doctor of Sciences.Doctor of Science (Latin: Scientiae Doctor), usually abbreviated Sc.D., D.Sc., S.D., or D.S., is an academic research degree awarded in a number of countries throughout the world. In some countries, "Doctor of Science" is the title used for the standard doctorate in the sciences; elsewhere the Sc.D. is a "higher doctorate" awarded in recognition of a substantial and sustained contribution to scientific knowledge beyond that required for a Doctor of Philosophy (PhD). It may also be awarded as an honorary degree.Doctoral advisor
A doctoral advisor (also dissertation director or dissertation advisor) is a member of a university faculty whose role is to guide graduate students who are candidates for a doctorate, helping them select coursework, as well as shaping, refining and directing the students' choice of sub-discipline in which they will be examined or on which they will write a dissertation. Students generally choose advisors based on their areas of interest within their discipline, their desire to work closely with particular graduate faculty, and the willingness and availability of those faculty to work with them.
In some countries, the student's advisor serves as the chair of the doctoral examination or dissertation committees. In some cases, though, the person who serves those roles may be different from the faculty member who has most closely advised the student. For instance, in the Dutch academic system, only full professors (hoogleraren) may chair doctoral examinations, so students who have been advised by lower-ranked faculty members will have a full professor as their official advisor (or promotor) and their actual advisor as co-promotor. In other countries, such as Spain, the doctoral advisor has the role of a mentor, but is not allowed to form part of the examination committee. This is a body of 5 experts independently selected by the rectorate among 10 candidates proposed by the university's department.
An academic genealogy may be traced based on student's doctoral advisors, going up and down the lines of academic "descent" in a manner analogous to a traditional genealogy.Doctorate
A doctorate (from Latin docere, "to teach") or doctor's degree (from Latin doctor, "teacher") or doctoral degree, is an academic degree awarded by universities, derived from the ancient formalism licentia docendi ("licence to teach"). In most countries, it is a research degree that qualifies the holder to teach at university level in the degree's field, or to work in a specific profession. There are a variety of names for doctoral degrees; the most common is the Doctor of Philosophy (PhD), which is awarded in many different fields, ranging from the humanities to scientific disciplines.
In the United States and some other countries, there are also some types of vocational, technical, or professional degrees that are referred to as doctorates. Professional doctorates historically came about to meet the needs of practitioners in a variety of disciplines. However, the necessity of these degrees may vary greatly across disciplines, making their significance unclear.
Many universities also award honorary doctorates to individuals deemed worthy of special recognition, either for scholarly work or for other contributions to the university or to society.E-Theses Online Service
E-Theses Online Service (EThOS) is a bibliographic database and union catalogue of electronic theses provided by the British Library, the National Library of the United Kingdom. As of March 2018 EThOS provides access to approximately 480,000 doctoral theses awarded by over 140 UK higher education institutions, with around 3000 new thesis records added every month.Essay
An essay is, generally, a piece of writing that gives the author's own argument — but the definition is vague, overlapping with those of a paper, an article, a pamphlet, and a short story. Essays have traditionally been sub-classified as formal and informal. Formal essays are characterized by "serious purpose, dignity, logical organization, length," whereas the informal essay is characterized by "the personal element (self-revelation, individual tastes and experiences, confidential manner), humor, graceful style, rambling structure, unconventionality or novelty of theme," etc.Essays are commonly used as literary criticism, political manifestos, learned arguments, observations of daily life, recollections, and reflections of the author. Almost all modern essays are written in prose, but works in verse have been dubbed essays (e.g., Alexander Pope's An Essay on Criticism and An Essay on Man). While brevity usually defines an essay, voluminous works like John Locke's An Essay Concerning Human Understanding and Thomas Malthus's An Essay on the Principle of Population are counterexamples.
In some countries (e.g., the United States and Canada), essays have become a major part of formal education. Secondary students are taught structured essay formats to improve their writing skills; admission essays are often used by universities in selecting applicants, and in the humanities and social sciences essays are often used as a way of assessing the performance of students during final exams.
The concept of an "essay" has been extended to other media beyond writing. A film essay is a movie that often incorporates documentary filmmaking styles and focuses more on the evolution of a theme or idea. A photographic essay covers a topic with a linked series of photographs that may have accompanying text or captions.Habilitation
Habilitation defines the qualification to conduct self-contained university teaching and is the key for access to a professorship in many European countries. Despite all changes implemented in the European higher education systems during the Bologna Process, it is the highest qualification level issued through the process of a university examination and remains a core concept of scientific careers in these countries.The degree is conferred for a habilitation thesis based on independent scholarship, which was reviewed by and successfully defended before an academic committee in a process similar to that of a doctoral dissertation. In some countries, a habilitation degree is a required formal qualification to independently teach and examine a designated subject at the university level.Irrelevant conclusion
Irrelevant conclusion, also known as ignoratio elenchi (Latin for 'ignoring refutation') or missing the point, is the informal fallacy of presenting an argument that may or may not be logically valid and sound, but (whose conclusion) fails to address the issue in question. It falls into the broad class of relevance fallacies.Irrelevant conclusion should not be confused with formal fallacy, an argument whose conclusion does not follow from its premises.Literature review
A literature review or narrative review is a type of review article. A literature review is a scholarly paper, which includes the current knowledge including substantive findings, as well as theoretical and methodological contributions to a particular topic. Literature reviews are secondary sources, and do not report new or original experimental work. Most often associated with academic-oriented literature, such reviews are found in academic journals, and are not to be confused with book reviews that may also appear in the same publication. Literature reviews are a basis for research in nearly every academic field. A narrow-scope literature review may be included as part of a peer-reviewed journal article presenting new research, serving to situate the current study within the body of the relevant literature and to provide context for the reader. In such a case, the review usually precedes the methodology and results sections of the work.
Producing a literature review may also be part of graduate and post-graduate student work, including in the preparation of a thesis, dissertation, or a journal article. Literature reviews are also common in a research proposal or prospectus (the document that is approved before a student formally begins a dissertation or thesis).Master of Arts
A Master of Arts (Latin: Magister Artium; abbreviated M.A.; also Latin: Artium Magister, abbreviated A.M.) is a person who was admitted to a type of master's degree awarded by universities in many countries, and the degree is also named Master of Arts in colloquial speech. The degree is usually contrasted with the Master of Science. Those admitted to the degree typically study linguistics, history, communication studies, diplomacy, public administration, political science, or other subjects within the scope of the humanities and social sciences; however, different universities have different conventions and may also offer the degree for fields typically considered within the natural sciences and mathematics. The degree can be conferred in respect of completing courses and passing examinations, research, or a combination of the two.
The Master of Arts traces its origin to the teaching license or Licentia docendi of the University of Paris.Master of Science
A Master of Science (Latin: Magister Scientiae; abbreviated MS, M.S., MSc, M.Sc., SM, S.M., ScM or Sc.M.) is a master's degree in the field of science awarded by universities in many countries or a person holding such a degree. In contrast to the Master of Arts degree, the Master of Science degree is typically granted for studies in sciences, engineering and medicine and is usually for programs that are more focused on scientific and mathematical subjects; however, different universities have different conventions and may also offer the degree for fields typically considered within the humanities and social sciences. While it ultimately depends upon the specific program, earning a Master of Science degree typically includes writing a thesis.Mathematics Genealogy Project
The Mathematics Genealogy Project is a web-based database for the academic genealogy of mathematicians. By 13 February 2019, it contained information on 238,725 mathematical scientists who contributed to research-level mathematics. For a typical mathematician, the project entry includes graduation year, thesis title, alma mater, doctoral advisor, and doctoral students.Postgraduate education
Postgraduate education, or graduate education in North America, involves learning and studying for academic or professional degrees, academic or professional certificates, academic or professional diplomas, or other qualifications for which a first or bachelor's degree generally is required, and it is normally considered to be part of higher education. In North America, this level is typically referred to as graduate school (or sometimes colloquially as grad school).
The organization and structure of postgraduate education varies in different countries, as well as in different institutions within countries. This article outlines the basic types of courses and of teaching and examination methods, with some explanation of their history.Rationalism
In philosophy, rationalism is the epistemological view that "regards reason as the chief source and test of knowledge" or "any view appealing to reason as a source of knowledge or justification". More formally, rationalism is defined as a methodology or a theory "in which the criterion of the truth is not sensory but intellectual and deductive".In an old controversy, rationalism was opposed to empiricism, where the rationalists believed that reality has an intrinsically logical structure. Because of this, the rationalists argued that certain truths exist and that the intellect can directly grasp these truths. That is to say, rationalists asserted that certain rational principles exist in logic, mathematics, ethics, and metaphysics that are so fundamentally true that denying them causes one to fall into contradiction. The rationalists had such a high confidence in reason that empirical proof and physical evidence were regarded as unnecessary to ascertain certain truths – in other words, "there are significant ways in which our concepts and knowledge are gained independently of sense experience".Different degrees of emphasis on this method or theory lead to a range of rationalist standpoints, from the moderate position "that reason has precedence over other ways of acquiring knowledge" to the more extreme position that reason is "the unique path to knowledge". Given a pre-modern understanding of reason, rationalism is identical to philosophy, the Socratic life of inquiry, or the zetetic (skeptical) clear interpretation of authority (open to the underlying or essential cause of things as they appear to our sense of certainty). In recent decades, Leo Strauss sought to revive "Classical Political Rationalism" as a discipline that understands the task of reasoning, not as foundational, but as maieutic.
In the 17th-century Dutch Republic, the rise of early modern-period rationalism — as a highly systematic school of philosophy in its own right for the first time in history — exerted an immense and profound influence on modern Western thought in general, with the birth of two highly influential rationalistic philosophical systems of Descartes (who spent most of his adult life in the Netherlands in the period 1628–1649) and Spinoza — namely Cartesianism and Spinozism. It was the 17th-century arch-rationalists like Descartes, Spinoza and Leibniz who have given the "Age of Reason" its name and place in history.In politics, rationalism, since the Enlightenment, historically emphasized a "politics of reason" centered upon rational choice, utilitarianism, secularism, and irreligion – the latter aspect's antitheism was later softened by the adoption of pluralistic methods practicable regardless of religious or irreligious ideology. In this regard, the philosopher John Cottingham noted how rationalism, a methodology, became socially conflated with atheism, a worldview:
In the past, particularly in the 17th and 18th centuries, the term 'rationalist' was often used to refer to free thinkers of an anti-clerical and anti-religious outlook, and for a time the word acquired a distinctly pejorative force (thus in 1670 Sanderson spoke disparagingly of 'a mere rationalist, that is to say in plain English an atheist of the late edition...'). The use of the label 'rationalist' to characterize a world outlook which has no place for the supernatural is becoming less popular today; terms like 'humanist' or 'materialist' seem largely to have taken its place. But the old usage still survives.Supervisor
A supervisor, or also known as foreman, overseer, facilitator, monitor, area coordinator, or sometimes gaffer, is the job title of a low level management position that is primarily based on authority over a worker or charge of a workplace. A supervisor can also be one of the most senior in the staff at the place of work, such as a Professor who oversees a PhD dissertation. Supervision, on the other hand, can be performed by people without this formal title, for example by parents. The term supervisor itself can be used to refer to any personnel who have this task as part of their job description.
An employee is a supervisor if he/she has the power and authority to do the following actions (according to the Ontario Ministry of Labour):
Give instructions and/or orders to subordinates.
Be held responsible for the work and actions of other employees.If an employee cannot do the above, legally, he or she is probably not a supervisor, but in some other category, such as a work group leader or lead hand.
A supervisor is first and foremost an overseer whose main responsibility is to ensure that a group of subordinates get out the assigned amount of production, when they are supposed to do it and within acceptable levels of quality, costs and safety.
A supervisor is responsible for the productivity and actions of a small group of employees. The supervisor has several manager-like roles, responsibilities, and powers. Two of the key differences between a supervisor and a manager are (1) the supervisor does not typically have "hire and fire" authority, and (2) the supervisor does not have budget authority.
Lacking "hire and fire" authority means that a supervisor may not recruit the employees working in the supervisor's group nor does the supervisor have the authority to terminate an employee. The supervisor may participate in the hiring process as part of interviewing and assessing candidates, but the actual hiring authority rests in the hands of a Human Resource Manager. The supervisor may recommend to management that a particular employee be terminated and the supervisor may be the one who documents the behaviors leading to the recommendation but the actual firing authority rests in the hands of a manager.
Lacking budget authority means that a supervisor is provided a budget developed by management within which constraints the supervisor is expected to provide a productive environment for the employees of the supervisor's work group. A supervisor will usually have the authority to make purchases within specified limits. A supervisor is also given the power to approve work hours and other payroll issues. Normally, budget affecting requests such as travel will require not only the supervisor's approval but the approval of one or more layers of management.
As a member of management, a supervisor's main job is more concerned with orchestrating and controlling work rather than performing it directly.Thesis statement
A thesis statement usually appears at the middle or end of the introductory paragraph of a paper, and it offers a concise summary of the main point or claim of the essay, research paper, etc. It is usually expressed in one sentence, and the statement may be reiterated elsewhere. It contains the topic and the controlling idea. There are two types of thesis statements: direct and indirect. The indirect thesis statement does not state the explicit reasons, while the direct thesis statement does. If I write, "I love New York for three reasons," the fact that I love New York is the topic, and "three reasons" are an indirect thesis statement. The essay will contain the three reasons. If I write, "I love New York because of the food, the jazz clubs and the Broadway Shows," that's a direct thesis statement that tells what each section or body paragraph is going to be about. The thesis statement is developed, supported, and explained in the course of the paper by means of examples and evidence. Thesis statements help organize and develop the body of the writing piece. They let readers know what the writer's statement is and what it is aiming to prove. A thesis statement does not necessarily forecast organization of an essay which can be more complex than its purpose.
