Plagiarism

 Plagiarism and Research Ethics

Research is a systematic process of collecting, analysing, interpreting, and presenting information to generate new knowledge or to examine existing knowledge from a new perspective. Since research contributes to academic and intellectual development, it must be conducted with honesty, transparency, originality, responsibility, and respect for others.

Two closely related concepts in academic research are plagiarism and research ethics. Plagiarism concerns the improper use or presentation of another person's intellectual work, whereas research ethics encompasses the broader moral and professional principles that guide the entire research process—from selecting a topic and collecting data to publishing the findings.

PART I: PLAGIARISM

2. Meaning of Plagiarism

The word plagiarism refers to the act of presenting another person's words, ideas, arguments, data, expressions, research findings, or creative work as one's own without proper acknowledgement.

In simple terms:

Plagiarism means using someone else's intellectual contribution without giving appropriate credit to its original source.

Plagiarism can occur deliberately or accidentally. Therefore, ignorance of citation conventions does not necessarily make the practice academically acceptable.

Important elements of plagiarism

• Use of another person's exact words without quotation and citation.

• Use of another person's ideas without acknowledgement.

• Copying another researcher's arguments or interpretations.

• Reproducing tables, graphs, figures, photographs, or diagrams without appropriate acknowledgement.

• Presenting translated material as one's own without citing the original.

• Using one's previous work improperly in a new publication.

• Submitting another person's work as one's own.

3. Why Plagiarism is a Serious Academic Problem

Plagiarism is considered serious because academic research depends fundamentally upon intellectual honesty and trust.

Major consequences include:

1. Violation of academic integrity

It violates the principle that researchers should honestly distinguish their own contribution from the contributions of others.

2. Misrepresentation of authorship

The plagiarist receives intellectual credit for work that was actually produced by someone else.

3. Damage to academic credibility

A researcher found guilty of plagiarism may lose the confidence of teachers, researchers, institutions, publishers, and readers.

4. Distortion of the research record

Plagiarised material can make it difficult to determine who originally developed an idea or finding.

5. Institutional consequences

Depending on institutional regulations, plagiarism can result in rejection of a dissertation or article, disciplinary proceedings, withdrawal of publication, or other academic penalties.

6. Legal and copyright implications

Some forms of unauthorised reproduction may also raise copyright issues, although plagiarism and copyright infringement are not identical concepts.

4. Types of Plagiarism

A. Direct Plagiarism

Direct plagiarism occurs when a researcher copies the exact words of another author without quotation marks and without proper citation.

Example:

Original:

Research methodology provides a systematic framework for conducting research.

If a student reproduces the sentence exactly without quotation and attribution, it constitutes direct plagiarism.

Prevention

• Use quotation marks for exact wording.

• Mention the author's name.

• Provide the appropriate citation and reference.

B. Paraphrasing Plagiarism

Paraphrasing is legitimate when a researcher expresses another author's idea in genuinely independent language and gives appropriate credit.

Paraphrasing plagiarism occurs when a researcher changes only a few words or rearranges the sentence structure while retaining the original idea and wording without acknowledgement.

Prevention

• Understand the original passage thoroughly.

• Write the idea independently.

• Cite the original source.

• Do not merely replace words with synonyms.

________________________________________

C. Mosaic or Patchwork Plagiarism

Mosaic plagiarism occurs when a researcher combines phrases, expressions, or sentence structures from different sources and presents the resulting text as original.

Characteristics

• Borrowed phrases from multiple sources.

• Minor alterations to original wording.

• Combination of several sources without adequate citation.

• The resulting paragraph may appear original but remains substantially dependent on borrowed material.

________________________________________

D. Source-Based Plagiarism

This occurs when a researcher provides misleading or inaccurate information about the source of a particular idea.

Examples include:

• Citing a source that was not actually consulted.

• Citing a secondary source as though it were the primary source.

• Providing an incorrect reference.

• Manipulating bibliographical information.

________________________________________

E. Self-Plagiarism

Self-plagiarism refers to the inappropriate reuse of one's own previously published or submitted work without adequate disclosure.

Although the researcher originally created the material, presenting previously used material as completely new can mislead readers about its originality.

Examples

• Reusing substantial portions of an earlier article in a new article without disclosure.

• Submitting the same assignment for different courses without permission.

• Republishing substantially the same research without transparent disclosure.

Important distinction

Self-plagiarism is different from ordinary reuse of one's previous ideas. Researchers can legitimately build on earlier work, but they should acknowledge previous publications and clearly identify what is new.

F. Accidental Plagiarism

Accidental plagiarism occurs without deliberate intention, often because of:

• Poor note-taking.

• Forgetting the source of information.

• Incorrect citation.

• Confusion between one's own ideas and borrowed ideas.

• Lack of knowledge about citation conventions.

Even when accidental, it should be corrected and prevented through careful research practices.

G. Translation Plagiarism

Translation plagiarism occurs when material is translated from another language and presented as original work without acknowledging the original source.

For example, translating a Bengali scholarly article into English and submitting it as one's own research constitutes plagiarism if the original source is not acknowledged.

H. Idea Plagiarism

Plagiarism is not limited to copying words. A researcher can also plagiarise a distinctive idea, argument, hypothesis, methodology, or interpretation if it is taken from another researcher without appropriate acknowledgement.

5. What Does Not Normally Constitute Plagiarism?

Not every similarity between two texts is plagiarism.

Examples include:

• Common knowledge that does not normally require citation.

• Properly quoted and cited material.

• Properly paraphrased and cited ideas.

• Standard terminology used within a discipline.

• Independently developed arguments.

• Facts that are genuinely common knowledge within the relevant academic context.

However, whether something qualifies as common knowledge depends on the discipline, audience, context, and source.

6. How to Avoid Plagiarism

1. Maintain accurate research notes

Record:

• Author

• Title

• Publication details

• Page number

• URL/DOI where relevant

• Date of access where required

2. Distinguish quotations from your own notes

When copying an exact sentence into research notes, immediately place it in quotation marks and record the source.

3. Cite borrowed ideas

Citation is required not only for direct quotations but also for ideas, arguments, data, and interpretations obtained from other researchers.

4. Use quotation marks correctly

Exact words should normally be clearly distinguished from your own writing.

5. Paraphrase genuinely

A proper paraphrase changes the structure and expression while preserving the meaning and acknowledges the original source.

6. Prepare a reference list

Every source cited in the research should be appropriately documented according to the required style.

7. Use plagiarism-detection software responsibly

Similarity-detection tools can help identify passages requiring review, but a similarity percentage by itself does not automatically establish plagiarism. Human academic judgement and examination of the sources remain important.
