two kinds of thesis

Think of yourself as a member of a jury, listening to a lawyer who is presenting an opening argument. You'll want to know very soon whether the lawyer believes the accused to be guilty or not guilty, and how the lawyer plans to convince you. Readers of academic essays are like jury members: before they have read too far, they want to know what the essay argues as well as how the writer plans to make the argument. After reading your thesis statement, the reader should think, "This essay is going to try to convince me of something. I'm not convinced yet, but I'm interested to see how I might be."

An effective thesis cannot be answered with a simple "yes" or "no." A thesis is not a topic; nor is it a fact; nor is it an opinion. "Reasons for the fall of communism" is a topic. "Communism collapsed in Eastern Europe" is a fact known by educated people. "The fall of communism is the best thing that ever happened in Europe" is an opinion. (Superlatives like "the best" almost always lead to trouble. It's impossible to weigh every "thing" that ever happened in Europe. And what about the fall of Hitler? Couldn't that be "the best thing"?)

A good thesis has two parts. It should tell what you plan to argue, and it should "telegraph" how you plan to argue—that is, what particular support for your claim is going where in your essay.

Steps in Constructing a Thesis

First, analyze your primary sources.  Look for tension, interest, ambiguity, controversy, and/or complication. Does the author contradict himself or herself? Is a point made and later reversed? What are the deeper implications of the author's argument? Figuring out the why to one or more of these questions, or to related questions, will put you on the path to developing a working thesis. (Without the why, you probably have only come up with an observation—that there are, for instance, many different metaphors in such-and-such a poem—which is not a thesis.)

Once you have a working thesis, write it down.  There is nothing as frustrating as hitting on a great idea for a thesis, then forgetting it when you lose concentration. And by writing down your thesis you will be forced to think of it clearly, logically, and concisely. You probably will not be able to write out a final-draft version of your thesis the first time you try, but you'll get yourself on the right track by writing down what you have.

Keep your thesis prominent in your introduction.  A good, standard place for your thesis statement is at the end of an introductory paragraph, especially in shorter (5-15 page) essays. Readers are used to finding theses there, so they automatically pay more attention when they read the last sentence of your introduction. Although this is not required in all academic essays, it is a good rule of thumb.

Anticipate the counterarguments.  Once you have a working thesis, you should think about what might be said against it. This will help you to refine your thesis, and it will also make you think of the arguments that you'll need to refute later on in your essay. (Every argument has a counterargument. If yours doesn't, then it's not an argument—it may be a fact, or an opinion, but it is not an argument.)

This statement is on its way to being a thesis. However, it is too easy to imagine possible counterarguments. For example, a political observer might believe that Dukakis lost because he suffered from a "soft-on-crime" image. If you complicate your thesis by anticipating the counterargument, you'll strengthen your argument, as shown in the sentence below.

Some Caveats and Some Examples

A thesis is never a question.  Readers of academic essays expect to have questions discussed, explored, or even answered. A question ("Why did communism collapse in Eastern Europe?") is not an argument, and without an argument, a thesis is dead in the water.

A thesis is never a list.  "For political, economic, social and cultural reasons, communism collapsed in Eastern Europe" does a good job of "telegraphing" the reader what to expect in the essay—a section about political reasons, a section about economic reasons, a section about social reasons, and a section about cultural reasons. However, political, economic, social and cultural reasons are pretty much the only possible reasons why communism could collapse. This sentence lacks tension and doesn't advance an argument. Everyone knows that politics, economics, and culture are important.

A thesis should never be vague, combative or confrontational.  An ineffective thesis would be, "Communism collapsed in Eastern Europe because communism is evil." This is hard to argue (evil from whose perspective? what does evil mean?) and it is likely to mark you as moralistic and judgmental rather than rational and thorough. It also may spark a defensive reaction from readers sympathetic to communism. If readers strongly disagree with you right off the bat, they may stop reading.

An effective thesis has a definable, arguable claim.  "While cultural forces contributed to the collapse of communism in Eastern Europe, the disintegration of economies played the key role in driving its decline" is an effective thesis sentence that "telegraphs," so that the reader expects the essay to have a section about cultural forces and another about the disintegration of economies. This thesis makes a definite, arguable claim: that the disintegration of economies played a more important role than cultural forces in defeating communism in Eastern Europe. The reader would react to this statement by thinking, "Perhaps what the author says is true, but I am not convinced. I want to read further to see how the author argues this claim."

A thesis should be as clear and specific as possible.  Avoid overused, general terms and abstractions. For example, "Communism collapsed in Eastern Europe because of the ruling elite's inability to address the economic concerns of the people" is more powerful than "Communism collapsed due to societal discontent."

How To Write 3 Types Of Thesis Statements

A thesis statement is “a short summary of the main idea, purpose, or argument of an essay that usually appears in the first paragraph.” It’s generally only one or two sentences in length.

A strong thesis statement is the backbone of a well-organized paper, and helps you decide what information is most important to include and how it should be presented.

What is a good thesis statement?

This thesis statement, for example, could open a paper on Dr. Martin Luther King Jr.’s importance as a civil rights leader: “Dr. Martin Luther King Jr. was one of the most influential figures of the American civil rights movement. His moving speeches and nonviolent protests helped unite a nation divided by race.”

This example lays out the writer’s basic argument (King was an important leader of the American civil rights movement), offers two areas of evidence (his speeches and nonviolent protests), and explains why the argument matters (united a divided nation).

A good thesis statement delivers a clear message about the scope of the topic and the writer’s approach to the subject. In contrast, poor thesis statements fail to take a position, are based solely on personal opinion, or state an obvious truth. For example, “Democracy is a form of government,” is a weak thesis statement because it’s too general, doesn’t adopt a stance, and states a well-known fact that doesn’t need further explanation.

What are the different types of thesis statements?

Thesis statements can be explanatory , argumentative , or analytical . The type of paper determines the form of the thesis statement.

1. Explanatory thesis statement

An explanatory thesis statement is based solely on factual information. It doesn’t contain personal opinions or make claims that are unsupported by evidence. Instead, it tells the reader precisely what the topic will be and touches on the major points that will be explored in the essay. An explanatory thesis statement is sometimes also called an expository thesis statement .

For example: The core components of a healthy lifestyle include a nutritious diet, regular exercise, and adequate sleep.

2. Argumentative thesis statement

In an argumentative essay, the writer takes a stance on a debatable topic. This stance, and the claims to back it up, is the argument . Unlike an explanatory thesis statement, an argumentative thesis statement allows the writer to take a position about a subject (e.g., the deeper meaning of a literary text, the best policy towards a social problem) and to convince readers of their stance. The body of the argumentative essay uses examples and other evidence to support the writer’s opinion.

For example: Shakespeares’s Taming of the Shrew uses humor, disguise, and social roles to criticize the lack of power women had in Elizabethan England.

3. Analytical thesis statement

An analytical thesis statement analyzes, or breaks down, an issue or idea into its different parts. Then, it evaluates the topic and clearly presents the order of the analysis to the reader.

For example: The school’s policy to start its school day an hour later revealed three related benefits: students were more alert and attentive in class, had a more positive about school, and performed better in their coursework.

How to write a thesis statement

Writing a thesis statement requires time and careful thought. The thesis statement should flow naturally from research and set out the writer’s discoveries. When composing a thesis statement, make sure it focuses on one main idea that can be reasonably covered within your desired page length. Try not to write about the entire history of America, for example, in a three-page paper.

Although deciding upon a thesis statement can be challenging and time-consuming, a strong thesis statement can make the paper both easier to write and more enjoyable to read. Don’t worry: we’re not going to leave you hanging! We’ve got a whole article to help you write an effective thesis statement here .

Thesis – Structure, Example and Writing Guide

Table of contents.

Definition:

Thesis is a scholarly document that presents a student’s original research and findings on a particular topic or question. It is usually written as a requirement for a graduate degree program and is intended to demonstrate the student’s mastery of the subject matter and their ability to conduct independent research.

History of Thesis

The concept of a thesis can be traced back to ancient Greece, where it was used as a way for students to demonstrate their knowledge of a particular subject. However, the modern form of the thesis as a scholarly document used to earn a degree is a relatively recent development.

The origin of the modern thesis can be traced back to medieval universities in Europe. During this time, students were required to present a “disputation” in which they would defend a particular thesis in front of their peers and faculty members. These disputations served as a way to demonstrate the student’s mastery of the subject matter and were often the final requirement for earning a degree.

In the 17th century, the concept of the thesis was formalized further with the creation of the modern research university. Students were now required to complete a research project and present their findings in a written document, which would serve as the basis for their degree.

The modern thesis as we know it today has evolved over time, with different disciplines and institutions adopting their own standards and formats. However, the basic elements of a thesis – original research, a clear research question, a thorough review of the literature, and a well-argued conclusion – remain the same.

Structure of Thesis

The structure of a thesis may vary slightly depending on the specific requirements of the institution, department, or field of study, but generally, it follows a specific format.

Here’s a breakdown of the structure of a thesis:

This is the first page of the thesis that includes the title of the thesis, the name of the author, the name of the institution, the department, the date, and any other relevant information required by the institution.

This is a brief summary of the thesis that provides an overview of the research question, methodology, findings, and conclusions.

This page provides a list of all the chapters and sections in the thesis and their page numbers.

Introduction

This chapter provides an overview of the research question, the context of the research, and the purpose of the study. The introduction should also outline the methodology and the scope of the research.

Literature Review

This chapter provides a critical analysis of the relevant literature on the research topic. It should demonstrate the gap in the existing knowledge and justify the need for the research.

Methodology

This chapter provides a detailed description of the research methods used to gather and analyze data. It should explain the research design, the sampling method, data collection techniques, and data analysis procedures.

This chapter presents the findings of the research. It should include tables, graphs, and charts to illustrate the results.

This chapter interprets the results and relates them to the research question. It should explain the significance of the findings and their implications for the research topic.

This chapter summarizes the key findings and the main conclusions of the research. It should also provide recommendations for future research.

This section provides a list of all the sources cited in the thesis. The citation style may vary depending on the requirements of the institution or the field of study.

This section includes any additional material that supports the research, such as raw data, survey questionnaires, or other relevant documents.

How to write Thesis

Here are some steps to help you write a thesis:

• Choose a Topic: The first step in writing a thesis is to choose a topic that interests you and is relevant to your field of study. You should also consider the scope of the topic and the availability of resources for research.
• Develop a Research Question: Once you have chosen a topic, you need to develop a research question that you will answer in your thesis. The research question should be specific, clear, and feasible.
• Conduct a Literature Review: Before you start your research, you need to conduct a literature review to identify the existing knowledge and gaps in the field. This will help you refine your research question and develop a research methodology.
• Develop a Research Methodology: Once you have refined your research question, you need to develop a research methodology that includes the research design, data collection methods, and data analysis procedures.
• Collect and Analyze Data: After developing your research methodology, you need to collect and analyze data. This may involve conducting surveys, interviews, experiments, or analyzing existing data.
• Write the Thesis: Once you have analyzed the data, you need to write the thesis. The thesis should follow a specific structure that includes an introduction, literature review, methodology, results, discussion, conclusion, and references.
• Edit and Proofread: After completing the thesis, you need to edit and proofread it carefully. You should also have someone else review it to ensure that it is clear, concise, and free of errors.
• Submit the Thesis: Finally, you need to submit the thesis to your academic advisor or committee for review and evaluation.

When to Write Thesis

The timing for writing a thesis depends on the specific requirements of the academic program or institution. In most cases, the opportunity to write a thesis is typically offered at the graduate level, but there may be exceptions.

Generally, students should plan to write their thesis during the final year of their graduate program. This allows sufficient time for conducting research, analyzing data, and writing the thesis. It is important to start planning the thesis early and to identify a research topic and research advisor as soon as possible.

In some cases, students may be able to write a thesis as part of an undergraduate program or as an independent research project outside of an academic program. In such cases, it is important to consult with faculty advisors or mentors to ensure that the research is appropriately designed and executed.

It is important to note that the process of writing a thesis can be time-consuming and requires a significant amount of effort and dedication. It is important to plan accordingly and to allocate sufficient time for conducting research, analyzing data, and writing the thesis.

Characteristics of Thesis

The characteristics of a thesis vary depending on the specific academic program or institution. However, some general characteristics of a thesis include:

• Originality : A thesis should present original research findings or insights. It should demonstrate the student’s ability to conduct independent research and contribute to the knowledge in their field of study.
• Clarity : A thesis should be clear and concise. It should present the research question, methodology, findings, and conclusions in a logical and organized manner. It should also be well-written, with proper grammar, spelling, and punctuation.
• Research-Based: A thesis should be based on rigorous research, which involves collecting and analyzing data from various sources. The research should be well-designed, with appropriate research methods and techniques.

9 Different Types of Thesis Statements: With Examples for Each

Types of Thesis Statements

A strong thesis statement is a fundamental part of a well-structured argumentative essay or academic paper. It holds various important purposes. 

Some of the purposes of a thesis statement include making the paper’s focus clear, guiding the writer, organizing the essay’s structure, enhancing clarity and understanding, and engaging the readers. 

It also helps the writer engage in critical thinking, enhances the strength of the essay’s argument, and improves consistency. A thesis statement is usually part of the evaluative criterion. 

The thing that differentiates a thesis statement from another is its particular characteristics and purpose. Different papers or essays require different types of thesis statements. 

This article will discuss the different types of thesis statements in terms of their definition and explanation, provide examples for those statements, and demonstrate when to use them. 

Different Types of Thesis Statements

1. the expository thesis statement.

This is a type of thesis statement used in research papers or expository essays. It is a clear and concise statement of the central argument or point of the essay.

The expository thesis statement is meant to explain, inform, or describe the topic that is being discussed.

It is neutral because its aim is not to persuade readers to adopt a particular perspective. It straightforwardly presents objective information and facts. 

One example of an expository thesis statement includes:  “The principles of Newton’s laws of motion lay the foundation for understanding the fundamental behavior of objects in the physical world.”

Another example is:  “The process of photosynthesis, in which plants convert sunlight into energy, is a crucial part of the ecosystem’s energy cycle.”

Expository thesis statements can be used in situations where the aim is to explain a concept, provide information, describe a process, or present objective facts without trying to persuade the audience. 

As such, expository thesis statements can be used in informative essays, expository research papers, how-to guides, and descriptive essays. 

2. The Argumentative Thesis Statement

This is a thesis statement used in persuasive or argumentative essays . It presents assertive, clear, and debatable claims that the author or writer wishes to support using logical reasoning and evidence within the essay. 

The argumentative thesis statement takes a stance on a particular viewpoint to persuade the reader to concur with that point of view. 

An example of the argumentative thesis statement includes:  “The government should implement stricter gun control laws to reduce the incidence of gun violence in the United States.”

Another good example is:  “Social media has a detrimental impact on mental health, as it promotes unrealistic standards and encourages constant comparison with others.”

As aforementioned, argumentative thesis statements are meant to convince, persuade, or argue for a specific viewpoint or position on a debatable or controversial issue.

Therefore, argumentative thesis statements can be used in persuasive essays, discussions and debates, controversial topics, and opinion editorials. 

3. The Analytical Thesis Statement

These are thesis statements used in research papers or analytical essays. They focus on breaking down and examining complex issues or topics into their basic parts and evaluating how they relate to each other. 

The main purpose of an analytical thesis statement is to give insight, understanding, and interpretation instead of informing or persuading the audience. 

One example of an analytical thesis statement is:  “The economic crisis of 2008 can be attributed to a combination of factors, including risky financial practices, regulatory failures, and the burst of the housing bubble.”

The second example is:  “In Shakespeare’s play ‘Hamlet,’ the character of Hamlet undergoes a profound transformation from a hesitant and indecisive prince to a vengeful and resolute avenger.”

The analytical thesis statement is used when the objective is to interpret, evaluate, or dissect a text, subject, or idea in a critical and detailed manner. 

Such statements can be used in literary analysis essays, critical essays, research papers, comparative essays, and interdisciplinary studies. 

4. The Comparative Thesis Statement

This is a thesis statement used in research papers or essays that are meant to compare and contrast two or more ideas, subjects, texts, or phenomena. 

A comparative thesis statement highlights the similarities and differences among the things or subjects that are being compared.

They give a debatable, focused, and clear claim meant to be the foundation for comparative analysis. 

The first example of such a comparative thesis statement is:  “A comparison of Eastern and Western philosophies reveals fundamental differences in their views on the self, the nature of reality, and the path to enlightenment.”

The second example is : “When assessing the impact of two different economic policies, a comparison of austerity measures and stimulus spending reveals varying effects on economic growth and unemployment rates.”

Such statements are used in comparative essays, literacy and textual analysis, cultural and historical studies, argumentative essays, and academic research. 

5. The Narrative Thesis Statement

The narrative thesis statement is used in storytelling contexts or narrative essays. It provides the main theme, point, or message the writer or narrator wants to convey.

It is focused on the purpose of the narrative in that it encapsulates the main lesson, idea, or experience the writer or narrator wishes to convey. 

An example of the narrative thesis statement is:  “The story of my grandmother’s life in war-torn Vietnam reflects the strength and determination that can emerge from adversity.”

Another example includes: “In the narrative of my childhood summers spent at the family cabin, I discovered the importance of cherishing simple moments with loved ones.”

Such thesis statements can be used in narrative essays, memoirs, personal reflections, oral storytelling, and creative writing. 

6. The Persuasive Thesis Statement

This is a thesis statement used in speeches, argumentative essays, and persuasive essays. Its main purpose is to give a clear and debatable claim which the writer intends to support, argue, and persuade the audience to accept. 

Persuasive thesis statements take a clear position concerning a controversial topic or issue and aim to convince the readers of the validity of that stance. 

An example of such a thesis statement is:  “The death penalty should be abolished because it is inherently inhumane, prone to error, and does not act as a deterrent to crime.”

Another example is:  “Public schools should implement comprehensive sex education programs to reduce teen pregnancy rates and promote responsible sexual behavior.”

Persuasive thesis statements can be used in argumentative essays, persuasive essays, speeches and debates, op-eds and editorials, and policy proposals. 

7. The Descriptive Thesis Statement

The descriptive thesis statement aims to paint a clear or vivid picture of an object, subject, experience, or place. 

It focuses on clearly describing the topic or conveying a specific feeling or impression about the topic. It helps the reader know what to expect when it comes to imagery, emotions, or sensory details in the essay. 

An example of a descriptive thesis statement is: “ The bustling, vibrant market in Marrakech, with its vibrant colors, exotic spices, and the hum of haggling, immerses visitors in the rich tapestry of Moroccan culture.”

Another example includes:  “The abandoned, dilapidated house at the end of the street, with broken windows and overgrown ivy, exudes an eerie and haunted aura.”

Such statements can be used in travel writing, descriptive essays, creative writing, art and film analysis, and immersive storytelling. 

8. The Problem-Solution Thesis Statement

This is a thesis statement primarily used in reports, essays, or papers meant to address a particular problem or issue and propose the course of action or solution to resolve the issue. 

The problem-solution thesis statement’s purpose is to recognize a significant issue and present an actionable and clear plan or solution to address it. 

An example of such a thesis statement is:  “The rising levels of air pollution in major cities can be mitigated by implementing stricter emission standards for vehicles and promoting the use of public transportation.”

Another example includes:  “To combat the obesity epidemic among children, schools should incorporate healthier meal options, increase physical education requirements, and promote nutritional education.”

The thesis statement can be used in policy proposals, business reports, problem-solving essays, community action plans, and scientific research. 

9. The Cause and Effect Thesis Statement

Finally, the cause-and-effect thesis statement is meant to explore and explain the connections between phenomena, actions, or events by recognizing the causes and their effects. 

Such thesis statements establish particular causal relationships by explaining how one action or event leads to another, and the reasons their connections are important. 

One example of a cause-and-effect thesis statement is:  “The excessive use of social media among teenagers can lead to increased feelings of loneliness and anxiety, as it hinders face-to-face social interactions and promotes social comparison.”

Another example includes:  “The decline of bee populations, caused by pesticide use and habitat destruction, has a cascading effect on food production and biodiversity, endangering global ecosystems.”

The thesis statement can be used in scientific research, cause and effect essays, historical analysis, environmental studies, and social and economic studies. 

A strong thesis statement is a very important part of a well-structured argumentative essay or academic paper.

What differentiates a thesis statement from another is its particular characteristics and purpose. Different papers or essays require different types of thesis statements.

Therefore, it is essential to first identify the type of paper or essay before deciding on the thesis statement to use.

Types of Theses

Three types of gallatin ma theses.

Each graduate student in the Gallatin School completes a final thesis as the culmination of their work toward a Master of Arts degree. The thesis may take one of three forms: a research thesis, an artistic thesis, or a project thesis. In each case, the thesis represents a synthesis of the student’s accumulated knowledge and skill and an opportunity to display the ideas, practices and skills learned through the program. While the master’s thesis, unlike a doctoral dissertation, does not have to create new knowledge or break new ground, it does display the student’s ability to go beyond the mere collection of information into synthesis, analysis, judgment and interpretation. Moreover, it should demonstrate the student’s familiarity with a substantial body of thought and literature and illustrate mastery of some self-chosen field of study.

Below you will find descriptions of the three types of theses: 

Research Thesis

Artistic thesis, project thesis.

Current MA students who are interested in seeing sample theses should consult the Gallatin Master's Thesis Archive , which is accessible with an NYU Net ID.

Students pursuing the research option produce and defend a substantial research essay, the thesis of which is demonstrably related to the student’s course of study and ongoing conversations with the primary adviser. The adviser and defense panelists are the ultimate arbiters of whether the thesis satisfies a reasonable understanding of a project worthy of the master’s degree. However, in general and at minimum, a successful Gallatin MA research thesis demonstrates sufficient mastery of relevant academic fields as well as a critical grasp of the scholarship and methods that currently define those fields. The thesis essay is a logically-constructed argument that presents its central points on the basis of research and critical interpretation. The sources and objects of study may cover the spectrum from archival materials to critical theory to statistical surveys and personal interviews, but the student should carefully choose sources in consultation with the primary adviser, and with reference to questions about what constitutes legitimate source within the student’s field(s). The research thesis essay must be more than a "review of the literature" but the demand for original findings is lower than that faced by doctoral candidates. Significantly original contributions are of course highly commendable, but the excellence of an MA research thesis essay may lie in its critical and creative synthesis, articulation of a fresh perspective on the work of others, or identification of new, research-based questions that themselves shed light on existing problems within fields. Generally speaking, the final research thesis essay should be at least 50 pages and not exceed 80 pages (not including appendices and bibliographic material). Students and advisers are encouraged to talk with the program's academic directors about these expectations whenever necessary.

back to top

The artistic thesis is appropriate for those students who wish to display the creative process in the performing, visual or literary arts. A student might make a film or video; choreograph an evening of dance; act in a play; mount an exhibit of paintings; write a screenplay, novel, play or collection of short stories; or choose another artistic endeavor. The artistic thesis represents the culmination of a Gallatin arts concentration in which the student has studied the genre under consideration.

The artistic thesis comprises both the artistic project and three accompanying essays. Therefore, you should conceive of the artistic thesis as a unified piece composed of the creative work and the essays which enhance it. Members of the faculty committee will assess both the artistic work and the essays. The essays include:

• an academic research paper related to the field of artistic work;
• an essay on artistic aims and process;
• a technical essay.

Please note: The technical essay does not apply to those students who are submitting a literary work.

Some General Advice

Be careful to keep records and a log of the artistic project as it evolves. This information can be used in the Technical Essay.

If a student is writing a work of fiction, poems, a play, etc., for the thesis, the student will submit this work to their adviser and other readers along with the essays. However, if the student is presenting a performance, they will need to arrange to have their adviser and other members of their committee see the performance. The student is responsible for coordinating schedules and for notifying committee members so that everyone can view the piece. The student should notify the thesis reviewer of the date of the performance at least one month in advance. In the event that one or more of the committee cannot attend the scheduled event, the student should arrange to have the performance videotaped so people can see it later. Except in unusual circumstances, the student must submit the first draft of the thesis to their adviser no more than three months after the performance.

Essays for the Artistic Thesis

Background Research Essay

As stated above, this essay follows the description for the standard research essay. It is a scholarly endeavor and differs from the standard essay in terms of length and focus. The length is approximately 25 to 40 pages. The focus of the essay is related to the artistic work and explores some aspect of that work that the student wishes to study and develop through outside research. The essay might take the form of an analysis of a performance or literary genre; a history of an art form or phenomenon; a philosophical study of an aesthetic concept; or a critical/biographical analysis of the work of an influential artistic figure.

Artistic Aims Essay

In this essay, the student is required to articulate their goals in mounting their particular artistic project. For example, what was the student trying to accomplish in writing short stories, a screenplay, a novel, presenting an evening of dances or songs, making a film or mounting an art exhibit? What were the aesthetic choices made and why?  The student should also explain their approach to the artistic work (their style, genre, or school), any relevant influences on the work, how the student's training influenced their artistic choices, and the student's intentions for particular elements of the creative work. After the student has carefully and clearly articulated these goals, they need to explain how their actual artistic work meets the stated goals. The student should use examples from their artistic project to illustrate these ideas. This essay should be approximately 10-15 pages in length.

Technical Essay

This essay is a description of the steps the student actually took to physically mount their production.  The student will need to include such technical details as arranging for rehearsal and performance space; choosing the performers; finding/creating, costumes, materials, lights; raising funds and getting institutional support. This essay should be approximately 10 pages in length.

Students may submit a portfolio, if appropriate. This would consist of any material, such as photos, slides, fliers, programs, videotapes, audiotapes etc. which might constitute an appendix and which might be helpful to a fuller understanding of the thesis.

The project thesis consists of two elements: (1) the project, a professional activity designed and executed primarily by the student as a way of solving a problem, and (2) an accompanying essay about the project. This thesis is especially appropriate for students in such fields as business, education, social work or public administration. The project thesis may appeal to those students who are active in their profession and who take responsibility for the creation of some kind of program or practice.

Students should understand that the project cannot simply propose a professional activity; the design for such an activity must actually be carried out (at least in a pilot version) and evaluated. Some examples of projects: a student in education may develop and apply a new strategy for teaching reading to recent immigrants; a person working in a corporation may construct new methods for managing financial information; or a community worker in a settlement house may organize a group of local residents to combat drug abuse.

At each step, the student should be careful to keep in touch with their adviser and with any other expert who can help them in their process. The student should keep careful records of the process by taking detailed notes of conversations, meetings, interviews, etc.  If at all possible, the student should arrange to have the members of their committee, especially their adviser, witness the project first-hand: Visit the site, talk with key actors, watch the program in operation. (This direct contact is highly recommended, but not required.)

Essays for the Project Thesis

The project thesis essay may take a number of forms and include a range of information. It ought to discuss at least the following elements:

Consider the institutional or social context within which the project takes place. Describe the organization, the potential clientele or participants, and the larger environment (social, economic and political conditions surrounding the problem and the project).

Describe the particular problem or need that you address in the project. What causes that problem? How extensive is it? Have other attempts to solve the problem been made; if so, what were their shortcomings, and why are you trying another approach? Place the problem in its professional and academic context by referring to the appropriate literature. Program

Describe the goals and objectives of the project and what the student hoped to accomplish. Describe how the program was designed and structured; for example, what kinds of activities did participants engage in, and in what sequence? What kinds of resources and techniques were used? Justify the strategies and tactics used by citing appropriate professional and academic literatures.

Implementation

Describe how the plan was carried out. Use as much detail as needed to give the reader a sense of what actually happened, and to indicate the extent to which the reality matched the plan.

Describe the criteria for assessing the project and evaluation methods used. Justify the criteria and methods by referring to appropriate literatures. To what extent did the project accomplish the goals and objectives identified earlier?

Citing relevant literature and the practical contingencies of the project, explain why the project did or did not achieve its stated purposes. Describe the factors (political, social, organizational, financial, psychological, etc.) that contributed to the process and to the outcomes. What changes--either conceptual or practical--would the student make if they were to repeat or extend the project? What would the student leave in place? Describe what was learned from the project about the original problem and about the student's strategy and tactics. Also consider the professional and theoretical implications of the project.

If necessary, put relevant documentary materials (flyers, important correspondence, budgets, etc.) in appendices.

Types of Thesis Papers

High School Writing Styles

A successful thesis paper is the ticket to ending a course or graduate program on a high note. Before you begin writing, it is important to know which type of thesis you need to write. Elements such as a thesis statement, textual support and references will vary, depending on whether the paper is a persuasive, expository or analytical piece.

According to Purdue University's Online Writing Lab, a persuasive thesis makes a claim about a topic and justifies it with specific evidence. Thesis statements should reflect the main point of your argument.

Calgary Bible College provides this example of a persuasive thesis statement: "High school graduates should be required to take a year off to pursue community service projects before entering college in order to increase their maturity and global awareness." The part of the statement about increasing their maturity and global awareness makes the sentence ideal for a persuasive paper, since it expands upon and explains the initial argument.

When writing a persuasive paper, resist the tendency to simply state an opinion. Provide solid textual support for this opinion, and draw out its implications and advantages.

An expository is the most basic type of thesis paper and often the easiest to write. It simply explains a topic to an audience.

According to Calgary Bible College, an expositiory thesis might start with a sentence such as, "The life of the typical college student is characterized by time spent studying, attending class and socializing with peers." So, the thesis will expound on a college student's life in the three areas mentioned.

In an expository paper, it is important to make sure that your evidence is relevant to the theme of the paper.

Analytical theses also explain a given theme, but in more detail. These types of papers are common in mathematics and science courses, where data is analyzed. Analytical papers often are tied to a specific text or study, and unlike a persuasive paper, they are entirely factual.

"An analysis of the college admission process reveals two principal problems facing counselors: accepting students with high test scores or students with strong extracurricular backgrounds." From this statement, given as an example by Calgary Bible College, the paper will focus on studies that involve the college admission process and explore the two problems.

What this handout is about

This handout provides definitions and examples of the two main types of abstracts: descriptive and informative. It also provides guidelines for constructing an abstract and general tips for you to keep in mind when drafting. Finally, it includes a few examples of abstracts broken down into their component parts.

What is an abstract?

An abstract is a self-contained, short, and powerful statement that describes a larger work. Components vary according to discipline. An abstract of a social science or scientific work may contain the scope, purpose, results, and contents of the work. An abstract of a humanities work may contain the thesis, background, and conclusion of the larger work. An abstract is not a review, nor does it evaluate the work being abstracted. While it contains key words found in the larger work, the abstract is an original document rather than an excerpted passage.

Why write an abstract?

You may write an abstract for various reasons. The two most important are selection and indexing. Abstracts allow readers who may be interested in a longer work to quickly decide whether it is worth their time to read it. Also, many online databases use abstracts to index larger works. Therefore, abstracts should contain keywords and phrases that allow for easy searching.

Say you are beginning a research project on how Brazilian newspapers helped Brazil’s ultra-liberal president Luiz Ignácio da Silva wrest power from the traditional, conservative power base. A good first place to start your research is to search Dissertation Abstracts International for all dissertations that deal with the interaction between newspapers and politics. “Newspapers and politics” returned 569 hits. A more selective search of “newspapers and Brazil” returned 22 hits. That is still a fair number of dissertations. Titles can sometimes help winnow the field, but many titles are not very descriptive. For example, one dissertation is titled “Rhetoric and Riot in Rio de Janeiro.” It is unclear from the title what this dissertation has to do with newspapers in Brazil. One option would be to download or order the entire dissertation on the chance that it might speak specifically to the topic. A better option is to read the abstract. In this case, the abstract reveals the main focus of the dissertation:

This dissertation examines the role of newspaper editors in the political turmoil and strife that characterized late First Empire Rio de Janeiro (1827-1831). Newspaper editors and their journals helped change the political culture of late First Empire Rio de Janeiro by involving the people in the discussion of state. This change in political culture is apparent in Emperor Pedro I’s gradual loss of control over the mechanisms of power. As the newspapers became more numerous and powerful, the Emperor lost his legitimacy in the eyes of the people. To explore the role of the newspapers in the political events of the late First Empire, this dissertation analyzes all available newspapers published in Rio de Janeiro from 1827 to 1831. Newspapers and their editors were leading forces in the effort to remove power from the hands of the ruling elite and place it under the control of the people. In the process, newspapers helped change how politics operated in the constitutional monarchy of Brazil.

From this abstract you now know that although the dissertation has nothing to do with modern Brazilian politics, it does cover the role of newspapers in changing traditional mechanisms of power. After reading the abstract, you can make an informed judgment about whether the dissertation would be worthwhile to read.

Besides selection, the other main purpose of the abstract is for indexing. Most article databases in the online catalog of the library enable you to search abstracts. This allows for quick retrieval by users and limits the extraneous items recalled by a “full-text” search. However, for an abstract to be useful in an online retrieval system, it must incorporate the key terms that a potential researcher would use to search. For example, if you search Dissertation Abstracts International using the keywords “France” “revolution” and “politics,” the search engine would search through all the abstracts in the database that included those three words. Without an abstract, the search engine would be forced to search titles, which, as we have seen, may not be fruitful, or else search the full text. It’s likely that a lot more than 60 dissertations have been written with those three words somewhere in the body of the entire work. By incorporating keywords into the abstract, the author emphasizes the central topics of the work and gives prospective readers enough information to make an informed judgment about the applicability of the work.

When do people write abstracts?

• when submitting articles to journals, especially online journals
• when applying for research grants
• when writing a book proposal
• when completing the Ph.D. dissertation or M.A. thesis
• when writing a proposal for a conference paper
• when writing a proposal for a book chapter

Most often, the author of the entire work (or prospective work) writes the abstract. However, there are professional abstracting services that hire writers to draft abstracts of other people’s work. In a work with multiple authors, the first author usually writes the abstract. Undergraduates are sometimes asked to draft abstracts of books/articles for classmates who have not read the larger work.

Types of abstracts

There are two types of abstracts: descriptive and informative. They have different aims, so as a consequence they have different components and styles. There is also a third type called critical, but it is rarely used. If you want to find out more about writing a critique or a review of a work, see the UNC Writing Center handout on writing a literature review . If you are unsure which type of abstract you should write, ask your instructor (if the abstract is for a class) or read other abstracts in your field or in the journal where you are submitting your article.

Descriptive abstracts

A descriptive abstract indicates the type of information found in the work. It makes no judgments about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract describes the work being abstracted. Some people consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short—100 words or less.

Informative abstracts

The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the writer presents and explains all the main arguments and the important results and evidence in the complete article/paper/book. An informative abstract includes the information that can be found in a descriptive abstract (purpose, methods, scope) but also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is rarely more than 10% of the length of the entire work. In the case of a longer work, it may be much less.

Here are examples of a descriptive and an informative abstract of this handout on abstracts . Descriptive abstract:

The two most common abstract types—descriptive and informative—are described and examples of each are provided.

Informative abstract:

Abstracts present the essential elements of a longer work in a short and powerful statement. The purpose of an abstract is to provide prospective readers the opportunity to judge the relevance of the longer work to their projects. Abstracts also include the key terms found in the longer work and the purpose and methods of the research. Authors abstract various longer works, including book proposals, dissertations, and online journal articles. There are two main types of abstracts: descriptive and informative. A descriptive abstract briefly describes the longer work, while an informative abstract presents all the main arguments and important results. This handout provides examples of various types of abstracts and instructions on how to construct one.

Which type should I use?

Your best bet in this case is to ask your instructor or refer to the instructions provided by the publisher. You can also make a guess based on the length allowed; i.e., 100-120 words = descriptive; 250+ words = informative.

How do I write an abstract?

The format of your abstract will depend on the work being abstracted. An abstract of a scientific research paper will contain elements not found in an abstract of a literature article, and vice versa. However, all abstracts share several mandatory components, and there are also some optional parts that you can decide to include or not. When preparing to draft your abstract, keep the following key process elements in mind:

• Reason for writing: What is the importance of the research? Why would a reader be interested in the larger work?
• Problem: What problem does this work attempt to solve? What is the scope of the project? What is the main argument/thesis/claim?
• Methodology: An abstract of a scientific work may include specific models or approaches used in the larger study. Other abstracts may describe the types of evidence used in the research.
• Results: Again, an abstract of a scientific work may include specific data that indicates the results of the project. Other abstracts may discuss the findings in a more general way.
• Implications: What changes should be implemented as a result of the findings of the work? How does this work add to the body of knowledge on the topic?

(This list of elements is adapted with permission from Philip Koopman, “How to Write an Abstract.” )

All abstracts include:

• A full citation of the source, preceding the abstract.
• The most important information first.
• The same type and style of language found in the original, including technical language.
• Key words and phrases that quickly identify the content and focus of the work.
• Clear, concise, and powerful language.

Abstracts may include:

• The thesis of the work, usually in the first sentence.
• Background information that places the work in the larger body of literature.
• The same chronological structure as the original work.

How not to write an abstract:

• Do not refer extensively to other works.
• Do not add information not contained in the original work.
• Do not define terms.

If you are abstracting your own writing

When abstracting your own work, it may be difficult to condense a piece of writing that you have agonized over for weeks (or months, or even years) into a 250-word statement. There are some tricks that you could use to make it easier, however.

Reverse outlining:

This technique is commonly used when you are having trouble organizing your own writing. The process involves writing down the main idea of each paragraph on a separate piece of paper– see our short video . For the purposes of writing an abstract, try grouping the main ideas of each section of the paper into a single sentence. Practice grouping ideas using webbing or color coding .

For a scientific paper, you may have sections titled Purpose, Methods, Results, and Discussion. Each one of these sections will be longer than one paragraph, but each is grouped around a central idea. Use reverse outlining to discover the central idea in each section and then distill these ideas into one statement.

Cut and paste:

To create a first draft of an abstract of your own work, you can read through the entire paper and cut and paste sentences that capture key passages. This technique is useful for social science research with findings that cannot be encapsulated by neat numbers or concrete results. A well-written humanities draft will have a clear and direct thesis statement and informative topic sentences for paragraphs or sections. Isolate these sentences in a separate document and work on revising them into a unified paragraph.

If you are abstracting someone else’s writing

When abstracting something you have not written, you cannot summarize key ideas just by cutting and pasting. Instead, you must determine what a prospective reader would want to know about the work. There are a few techniques that will help you in this process:

Identify key terms:

Search through the entire document for key terms that identify the purpose, scope, and methods of the work. Pay close attention to the Introduction (or Purpose) and the Conclusion (or Discussion). These sections should contain all the main ideas and key terms in the paper. When writing the abstract, be sure to incorporate the key terms.

Highlight key phrases and sentences:

Instead of cutting and pasting the actual words, try highlighting sentences or phrases that appear to be central to the work. Then, in a separate document, rewrite the sentences and phrases in your own words.

Don’t look back:

After reading the entire work, put it aside and write a paragraph about the work without referring to it. In the first draft, you may not remember all the key terms or the results, but you will remember what the main point of the work was. Remember not to include any information you did not get from the work being abstracted.

Revise, revise, revise

No matter what type of abstract you are writing, or whether you are abstracting your own work or someone else’s, the most important step in writing an abstract is to revise early and often. When revising, delete all extraneous words and incorporate meaningful and powerful words. The idea is to be as clear and complete as possible in the shortest possible amount of space. The Word Count feature of Microsoft Word can help you keep track of how long your abstract is and help you hit your target length.

Kenneth Tait Andrews, “‘Freedom is a constant struggle’: The dynamics and consequences of the Mississippi Civil Rights Movement, 1960-1984” Ph.D. State University of New York at Stony Brook, 1997 DAI-A 59/02, p. 620, Aug 1998

This dissertation examines the impacts of social movements through a multi-layered study of the Mississippi Civil Rights Movement from its peak in the early 1960s through the early 1980s. By examining this historically important case, I clarify the process by which movements transform social structures and the constraints movements face when they try to do so. The time period studied includes the expansion of voting rights and gains in black political power, the desegregation of public schools and the emergence of white-flight academies, and the rise and fall of federal anti-poverty programs. I use two major research strategies: (1) a quantitative analysis of county-level data and (2) three case studies. Data have been collected from archives, interviews, newspapers, and published reports. This dissertation challenges the argument that movements are inconsequential. Some view federal agencies, courts, political parties, or economic elites as the agents driving institutional change, but typically these groups acted in response to the leverage brought to bear by the civil rights movement. The Mississippi movement attempted to forge independent structures for sustaining challenges to local inequities and injustices. By propelling change in an array of local institutions, movement infrastructures had an enduring legacy in Mississippi.

Now let’s break down this abstract into its component parts to see how the author has distilled his entire dissertation into a ~200 word abstract.

Example 2: Science Abstract

Luis Lehner, “Gravitational radiation from black hole spacetimes” Ph.D. University of Pittsburgh, 1998 DAI-B 59/06, p. 2797, Dec 1998

The problem of detecting gravitational radiation is receiving considerable attention with the construction of new detectors in the United States, Europe, and Japan. The theoretical modeling of the wave forms that would be produced in particular systems will expedite the search for and analysis of detected signals. The characteristic formulation of GR is implemented to obtain an algorithm capable of evolving black holes in 3D asymptotically flat spacetimes. Using compactification techniques, future null infinity is included in the evolved region, which enables the unambiguous calculation of the radiation produced by some compact source. A module to calculate the waveforms is constructed and included in the evolution algorithm. This code is shown to be second-order convergent and to handle highly non-linear spacetimes. In particular, we have shown that the code can handle spacetimes whose radiation is equivalent to a galaxy converting its whole mass into gravitational radiation in one second. We further use the characteristic formulation to treat the region close to the singularity in black hole spacetimes. The code carefully excises a region surrounding the singularity and accurately evolves generic black hole spacetimes with apparently unlimited stability.

This science abstract covers much of the same ground as the humanities one, but it asks slightly different questions.

Make a Gift

A Summary and Analysis of Amy Tan’s ‘Two Kinds’

By Dr Oliver Tearle (Loughborough University)

‘Two Kinds’ is a short story by the American author Amy Tan (born 1952), published as part of her book The Joy Luck Club in 1989. The story is about a young American girl born to Chinese parents; her mother pushes her to become a child prodigy, but the daughter resists.

A powerful tale about pushy parents and their children, ‘Two Kinds’ deserves some closer analysis to tease out its meaning and significance. First, though, here’s a quick recap of the story’s plot.

‘Two Kinds’: plot summary

The story is narrated in the first person by a Chinese-American woman, named Jing-mei, who is looking back on her upbringing in the United States. Her parents had emigrated to the US from China in 1949, and the narrator’s mother was convinced that, in America, anyone could become successful, rich, and famous.

She tells her daughter that she can become a child prodigy like the child firm star Shirley Temple, but when her mother takes her to have her hair curled like Temple’s, the result is a disaster and Jing-mei has to have her hair cut short like a boy’s. She longs to become a prodigy because she thinks that will make her perfect; if she fails to become one, she will be nothing.

Her mother next tries to turn Jing-mei into a fiercely intelligent girl who can match the feats of knowledge and memory achieved by other children, but the tests the mother sets her become more and more difficult. She feels bad for disappointing her mother, but when she catches sight of her own reflection in the mirror, she realises how strong she is, and decides to defy her mother, who eventually gives up trying to school her daughter into becoming a genius.

A few months later, her mother sees a Chinese girl playing the piano on the television, and makes her daughter start taking piano lessons. When Jing-mei confronts her mother about this, the mother denies trying to turn her daughter into a genius, claiming she just wants her to be the best she possibly can be. She is taught to play the piano by a retired neighbour, Mr Chong, who is deaf. Because he cannot hear the notes she is playing, the girl doesn’t bother to correct herself when she hits the wrong notes.

She is determined not to commit to it because her mother has pushed it so hard. When her mother enters Jing-mei into a talent competition, Jing-mei decides to sabotage it by not practising and performing badly. However, as she starts playing and hits the wrong notes, she longs for the performance to go well. Afterwards, her mother is ashamed by how badly she has done, and Jing-mei regrets throwing the performance away.

Two days later, however, the mother tries to force Jing-mei into resuming piano lessons. Her mother tells her that there are only ‘two kinds’ of daughters: those who are obedient and those who follow their own mind, and she insists on her daughter being the obedient kind. In response, Jing-mei says she wishes she wasn’t her mother’s daughter, or that she had died at birth like the children her mother had lost back in China. This stuns her mother, who stops trying to force her daughter to learn the piano.

Jing-mei tells us that, in the years that followed, she continually disappointed her mother, because she doesn’t share her view that she could be anything she wanted to be, but instead could ‘only be me’. When the narrator turns thirty, she is surprised when her mother offers to give her the piano as a birthday present. Even after all these years, her mother is convinced her daughter has a natural aptitude for music. Although Jing-mei doesn’t immediately take the piano off her parents, every time she sees it in their living room she feels proud.

At the end of the story, Jing-mei tells us that her mother recently died and she went round to the house to tune the piano. Opening it up, she finds the sheet music for the piece of music, ‘Pleading Child’, she had failed to play at the talent show. She notices that the piece opposite it in the book is called ‘Perfectly Contented’, and realises these are two halves of the same song.

‘Two Kinds’: analysis

‘Two Kinds’ is a story about the relationship between parents and their children, and what motivates a ‘pushy parent’ to encourage (or coerce?) their child into working hard to achieve something. Does the mother in the story have her daughter’s best interests at heart when she tries to make her learn the piano? Where does a parent’s well-meaning desire to see their child succeed spill over into interfering with the child’s desire not to do a particular thing?

These questions are given an extra twist by the fact that the narrator is Chinese-American, born in the US but to parents who have struggled to escape from Communist China (China became a Communist state in 1949, the same year Jing-mei’s parents fled the country, when Chairman Mao seized power) and who clearly believe in the American dream .

Jing-mei, however, does not share the immigrant’s view that America is a land where all dreams can come true, and her aspirations are lower but arguably more realistic: simply to do the best that she can and to be happy.

It is clear that Jing-mei’s mother is motivating her daughter to succeed partly because she wants her to have all the opportunities she never had as a child. She arguably feels it is her duty as a parent to push her daughter to become a prodigy for her own good. But she is also motivated by a desire to feel pride as a parent.

Is this pride, however, not merely the happiness derived from seeing one’s child flourishing, but something more personal and even egotistical? She feels she can vicariously enjoy her daughter’s success through her, as though she had somehow won the talent show herself.

This becomes obvious when Jing-mei overhears her mother boasting to a friend, Lindo Jong, about her daughter’s natural talent for music, and she realises that her mother is only making her learn the piano so she can brag to other mothers about how talented her daughter is. It is significant that, after the talent show, Jing-mei is disappointed that her mother doesn’t shout angrily at her when they get home.

She wants an opportunity to confront her mother and air her frustration at having to live out her mother’s own fantasies by becoming a child prodigy.

The story’s title, ‘Two Kinds’, is ostensibly explained by the mother’s comment to her daughter that there are two kinds of daughter: obedient and free-thinking. Ironically, her mother has fled a totalitarian state only to set up a petty tyrannical regime in her own home (you can take the girl out of Communism, but …).

Yet Tan’s title ‘Two Kinds’ does itself have two kinds of meaning: it can also refer to the final section of the story, in which Jing-mei discovers the other piece of music from the talent show, and realises – in a moment laden (perhaps too conveniently) with symbolism – that ‘Pleading Child’ is complemented by ‘Perfectly Contented’.

These are the ‘Two Kinds’ of person she has been: she had to struggle slowly through the years as a pleading child longing for independence and the right to choose what she pursued, but now she has reached adulthood, she is indeed perfectly contented, in a way that her mother never could be.

Jing-mei realises that doing your best and making yourself proud is the key to a happy life: trying to win talent shows or outdo other people (or, worse, other people’s children through your own child) is only going to leave you trapped in a perpetual cycle of goal-chasing and ambition-pursuing.

And yet, Amy Tan has Jing-mei point out that the latter was dependent on the former: in order to be fully content as an adult, she had to plead and fight for her own independence while growing up. Her journey mirrors her mother’s, oddly, in that they have both had to struggle out of situations where they were not allowed to be free, but the difference is that Jing-mei embraces her freedom whereas her mother didn’t know what to do with hers.

Instead, she had to live out her own thwarted ambitions through someone who is, now, free to pursue them. Except, of course, Jing-mei doesn’t want them, because they’re not her ambitions. One message of Tan’s ‘Two Kinds’ is that you cannot force someone to be free: they have to embrace it and define it in their own way, otherwise it is not worthy of being called freedom.

Regulation of growth and nutrient digestibility by supplemental myo-inositol and luteolin in pigs and chickens

Newborn animals undergo a lot of early-life stress that heavily impact on their long-term growth, performance, and welfare. Typically, the stress would indirectly interfere with the capacity of these neonates to utilize dietary nutrients and consequently impact tissue growth and development. In piglets, weaning is a stressful situation characterized by disruption of intestinal epithelial cell development which causes poor digestion of solid feed and a negative impact on absorption of nutrients especially in the post-gastric region. In addition, weaning in piglets could cause an increase in cellular assault by reactive oxygen species thereby potentially causing gut leakiness and paracellular loss of nutrients along the intestinal tract. In broiler chickens, access to feed may take up to 72 h following hatching which may affect their gut development as well as their gut microbiota. After the first feed ingestion, there is a sharp increase in the gut microbiota which triggers an increase in the development of the immune system as well as the gut. There is continuous attention on the strategies and nutritional interventions to mitigate or ameliorate the adverse effects of early life stressors in these food animals, especially in broiler chickens and piglets. In the studies described in this dissertation, myo-inositol (purely supplemented or phytase-induced) and luteolin were tested as nutritional strategies to mitigate the effects of early-life stressors on growth and the potential mechanisms by which myo-inositol and luteolin regulate growth were investigated.

In study I, the effect of myo-inositol on growth in 128 postweaning piglets fed protein-deficient corn-soy diets was tested. There were 4 dietary treatments in a randomized complete block design with body weight as the blocking factor. The treatments consisted of 1 positive control (PC) diet formulated to meet all the nutrient requirements of the piglets with a 20% crude protein (CP); the remaining 3 diets were the negative control (NC) diets with a 3% reduction in CP, a 2 g/kg myo-inositol supplemented negative control diet (NC+INO), and phytase (3,000 FTU/kg) supplemented negative control (NC+PHY) diet. The results showed that phytase enhanced the apparent total tract digestibility (ATTD) of P in the weanling pigs. Myo-inositol supplementation in a protein-deficient diet improved (P < 0.05) porcine plasma myo-inositol concentration while an in vitro myo-inositol incubation with intestinal epithelial cells increased the expression of genes that encode for Claudin-1, Claudin-3, Claudin-4, ZO-1, NaPiIIb, GLUT2, and SLC7A2. The in vitro analysis of tight junction integrity in the IPEC-J2 cells indicated by the transepithelial electrical resistance and FITC-Dextran permeability showed an enhancement in response to myo-inositol treatment. Although the in vivo study found that myo-inositol did not improve growth performance or ATTD, the in vitro myo-inositol enhanced markers of gut health and function.

In study II, the effect of myo-inositol on the growth of broiler chickens was tested. In this study, there were 6 experimental treatments based on two dietary protein levels (PC and NC) and three supplement types (BASAL, INO, and PHY) resulting in a 2 x 3 factorial arrangement in a completely randomized design. A total of 384 broiler chickens comprising 6 treatments with eight replicates per treatment and 8 birds per replicate were used. The birds were fed a common starter diet for the initial 7 days after they arrived at the poultry unit followed by a 14-day trial. The protein-deficient diet decreased the feed efficiency of the birds. Phytase addition increased (P < 0.05) the apparent ileal digestibility (AID) and ATTD of P and Ca in both PC and NC groups. The jejunal gut morphology was enhanced by supplemental phytase as indicated by an increase in villus height and the ratio of the villus height-to-crypt depth, coupled with an increase in serum myo-inositol concentration caused by both myo-inositol and phytase. In conclusion, myo-inositol showed a differential influence on growth performance, nutrient digestibility, and gut morphology.

In study III, the effects of luteolin on weanling pigs and IPEC-J2 cells were examined. A total of 48 piglets were randomly allotted to two dietary treatments consisting of a control group and a luteolin (LUT)-supplemented dietary group for a 4-week trial. A weekly assessment of the growth performance and expression of specific proteins in the jejunal mucosa was performed. In each dietary group, 8 piglets were slaughtered at weeks 1, 2, and 4 postweaning to collect blood, jejunal and ileal mucosa, and tissues. Luteolin supplementation numerically improved the ADG and G:F of the pigs. Luteolin feeding altered the jejunal and ileal gut morphology with increased villi height (P < 0.05) and villus height-to-crypt depth ratio (VCR, P < 0.05) in the jejunum and decreased crypt depth in the ileum. The effect of luteolin on IPEC-J2 global proteome and phosphor-proteome showed that luteolin could potentially improve intestinal barrier integrity by enhancing the abundance of proteins important in cell growth and survival.

In summary, dietary supplementation with myo-inositol and luteolin could regulate growth and nutrient digestibility in broiler chickens and weanling pigs by enhancing the integrity of intestinal cells and facilitating the expression of nutrient transporters that are significant in the uptake of nutrients across the lining of the gastrointestinal tract. Phytase supplementation improves the P release from phytate in the diets thereby alleviating its loss.
