1. Duties of authors

Reporting standards

In reports of original research, authors hold a paramount responsibility: to present a factual account of their work and objectively discuss its significance. Accuracy reigns supreme, demanding faithful representation of the underlying data. The manuscript should offer enough detail and reference points for any qualified researcher to replicate the findings. Fraudulent or intentionally misleading statements are deplorable lapses in ethical conduct and will not be tolerated. Beyond original research, reviews and professional publications must likewise uphold accuracy and objectivity. Even for editorial "opinion" pieces, transparency is paramount: readers deserve clear identification of such subjective content.

Data access and retention

As part of the editorial review process, authors may be requested to provide the research data underpinning their paper. Additionally, some journals have open data policies, necessitating data sharing. In such cases, authors should be prepared to grant public access to their data (when feasible) and ensure its retention for a reasonable period following publication. This commitment to data transparency strengthens research integrity and allows for independent verification and further exploration by the scientific community.

Originality and acknowledgment of sources

Authorship requires originality. Authors must ensure their work is their own, and any use of others' ideas, words, or data must be appropriately cited, quoted, and credited. Obtaining required permissions is paramount. Acknowledging the work of others is not just a formality, but an essential pillar of academic integrity.

Multiple, redundant or concurrent publication

Duplicate publication, meaning publishing essentially the same research in multiple primary journals, is unacceptable and undermines scientific integrity. Submitting the same manuscript to multiple journals concurrently is a particularly egregious form of this misconduct. Similarly, republishing previously published work in another journal is generally discouraged.

However, some specific types of articles, like clinical guidelines or translations, can be justifiably published in multiple journals under certain conditions. This requires explicit agreement and coordination between the authors and editors of all involved journals. Importantly, the secondary publication must reflect the same data and interpretation as the primary source, with clear citation of the original work.

Confidentiality

Information entrusted to researchers during confidential services, such as reviewing manuscripts or grant applications, is strictly confidential. Disclosing or utilizing this information without the express written consent of the author entrusted with the work would constitute a grave breach of professional ethics and a violation of trust.

Authorship of the paper

Authorship should be reserved for those who made significant contributions to the research, encompassing its conception, design, execution, or interpretation. All such individuals deserve co-authorship recognition. Others who provided substantial support, such as language editing, should be acknowledged separately.

The corresponding author has the crucial responsibility of ensuring accurate and appropriate co-authorship. This includes confirming all listed contributors deserve inclusion, no one deserving of recognition is omitted, and everyone listed has reviewed and approved the final manuscript, agreeing to its submission for publication.

Careful consideration of authorship order and inclusion is expected before submission. Definitive authorship lists should be provided with the initial manuscript. Any changes involving the addition, deletion, or rearrangement of authors will only be considered by the editor in exceptional circumstances and at their discretion. Such requests must be clearly flagged by the corresponding author, and all co-authors involved must agree to the proposed changes.

Ultimately, all authors collectively share responsibility for the work. Each individual author is accountable for addressing and resolving any questions regarding the accuracy or integrity of any aspect of the research.

Declaration of competing interests

The World Association of Medical Editors (WAME) defines a conflict of interest as "a clash between personal interests (competing interests) and an individual's duty to uphold scientific and publishing integrity, where an observer might question whether personal gain influenced their behavior or judgment." Authors should disclose any financial or personal ties, in the manuscript, that could be perceived as inappropriately biasing their work.

Transparency regarding research funding is crucial. Disclose all sources of financial support for the research and manuscript preparation, along with the sponsor's role (if any) in study design, data collection and analysis, interpretation, writing, and publication decisions. If sponsors had no involvement, state this clearly.

Examples of potential conflicts to disclose include employment, consulting roles, stock ownership, honoraria, paid expert testimony, patent applications, and grants or other funding. Early disclosure of potential conflicts is essential for building trust and safeguarding scientific integrity.

Notification of fundamental errors

Authors discovering a significant error or inaccuracy in their published work bear an ethical responsibility to act swiftly. They must promptly notify the journal editor and actively collaborate with them to retract or correct the paper as deemed necessary. Conversely, if an editor learns of such an error from a third party, the author owes prompt cooperation, including providing requested evidence to facilitate a resolution.

Image integrity

Image manipulation in scientific contexts must prioritize transparent presentation. Any alteration beyond adjustments to brightness, contrast, or color balance, particularly the addition, removal, or movement of features, is strictly prohibited. Such manipulations intended to enhance clarity are permissible, but any attempt to mislead or distort the data constitutes scientific misconduct and will be subject to appropriate consequences.

2. Guidelines for manuscript preparation

• The main text’s headings and subheadings should be numbered and formatted as follows:

 

Specific requirements

1. Title

• The title should be specific, concise, and informative.

• The title should clearly describe the content of the paper in the fewest possible words; 10 to 12 words are enough.

• Avoid abbreviations and formulas.

• Capitalize the first word of the title, proper nouns, and words after hyphen or colon.

Example:

Effect of levamisole on parameters of immune response and bacterial resistance of striped catfish (Pangasianodon hypophthalmus)

2. Authors and Affiliations

• Write each author’s full name, do not include author’s degrees.

• Use superscript (numbered consecutively) after each author’s name to indicate the author’s affiliation.

• Mark (*) to indicate the corresponding author.

Example:

To Nguyen Phuoc Mai1, Ly Van Khanh2*, Bui Lan Anh3 and Tran Thanh Truc1 1 College of Agriculture, Can Tho University, Vietnam 2 Mekong Delta Development Research Institute, Can Tho University 3 College of Aquaculture and Fisheries, Can Tho University *Correspondence: Ly Van Khanh (email: lvkhanh@ctu.edu.vn)

3. Abstract

• Should be no more than 200 words in length.

• Should briefly state the purpose of the research, methods used, primary results, and major conclusions.

• Should not contain any undefined abbreviations or unspecified references.

• If abbreviations are essential (three times at least), they must be defined at their first mention in the abstract.

Example: Introduction/Objective(s), Method(s), Result(s), Conclusion(s)

Experimental evidence suggests that white spot syndrome virus (WSSV) can be transmitted horizontally through water, via carrier organisms and/or by cannibalism of infected shrimp, but also vertically through infected brood stock. However, the mode(s) of WSSV transmission in shrimp farming systems and the epidemiological consequences are not well understood. In this study, molecular markers have been used to analyse the spread of WSSV within and between farms in Viet Nam for two different farming systems: improved-extensive and semi-intensive. Samples were periodically obtained from twenty improved-extensive shrimp ponds and twenty-three semi-intensive shrimp ponds applying different sampling schemes. PCR-genotyping was employed using three WSSV molecular marker loci: the variable tandem repeat regions (VNTR) in ORF75, ORF94, and ORF125 (GenBank AF369029). An analysis on the combined results of all three VNTR marker loci made it possible to follow transmission pathways of WSSV in the respective shrimp farming systems. The transmission of WSSV infection on improved extensive shrimp farms appeared mainly due to the recycling of WSSV over time in the same pond, whereas in semi-intensive shrimp farms transmission of WSSV was mainly from neighboring ponds. These findings provide important information for field applications by suggesting pathway-specific control strategies.

Rational reflection can help us to detect inconsistencies and fallacious argumentation, and to uncover misuse of evidence. It helps us to see whether a choice coheres with our given judgement, including our judgements about what kind of person we ought to be. It also helps us to evaluate the ways we are attached to other people, and to carry out our altruistic obligations and goals more effectively.
