Target audience

Professionals, Researchers, and Scholars, with interest in research in fields of architecture, urban planning, and specialties related areas, nationally and internationally.

Peer review

All papers submitted to the journal are peer-reviewed. The review system is double blind

Authorship policy

The proposed papers for publication in the journal must be unpublished works, not allowing publication in another journal. Submitted papers should not be reviewed simultaneously in other journals. They must also conform to the format and editorial policy of the journal.

Nexo Revista Científica considers that an author of a published manuscript will have made a significant intellectual contribution to it. Following the indications of the Committee on Publication Ethics (COPE) authors must comply with the following criteria:

  • Substantial contributions to the concept or design of the manuscript, data acquisition, analysis, or interpretation.
  • Editing or critical review of the most relevant intellectual content of the manuscript.
  • Final approval of the version to be published.
  • Assume responsibility for all aspects of the work, guaranteeing the research and resolution of all issues related to its precision and integrity.

Those who do not comply with the above criteria can be only listed in acknowledgments. To avoid the use of fictional or usurped identifies, it is recommended that all the authors agree among themselves on the respective roles and order of listing of co-authors.

About the contributions by author:
To specify the content or contribution of each author of the work, it is recommended to utilize the criteria established in CRediT (Contributor Roles Taxonomy):

Order of contribution:
To determine the order of authors in an article, the authors can utilize any of the three most commonly used practices:

  • First last author emphasis approach (FLAE): The first and last authors are given equal importance. Authors between them are listed in order of decreasing importance.
  • Sequence determines credit approach (SDC): The order indicates the rank of importance.
  • Equal contribution norm (EC): Alphabetical order is utilized among authors of similar contribution to avoid disputes in collaboration groups.

Changes in authorship

Nexo Revista Científica follows the indications of the COPE Flow diagrams, in which any addition, elimination, or reordering of names must be accomplished before the manuscript has been accepted and only with the approval of the journal editor.

Conflicts of interest
Nexo Revista Científica follows the indications of the COPE Flow diagrams in cases of conflict of interest: (a) Conflict of interest not revealed in a submitted manuscript ,and (b) Conflict of interest not revealed in a published artícle.

In the case of conflict of interest declared by the authors regarding financial or personal relationships with any public or private entity that could influence (intentionally) the results of the work, this should be communicated at the moment of submission of the manuscript.

Grievances and appeals

Disputes, grievances, and complaints by readers, authors, and reviewers can be directed to the General Editor at the email address of Nexo Revista Científica (revistanexo@uni.edu.ni).

The members of the Editorial Committee will respond promptly, once the presented arguments are analyzed, discussed, and verified.

When the reason for the complaint or appeal implies a breach of the ethical good practices established by Nexo Revista Científica and COPE in its Code of Conduct, the Flow Diagrams of COPE will be followed in each case.

Post-publication revisions

The articles and other types of documents that have been published in this journal will be maintained current, exact, and unaltered to the extent possible. Nonetheless, exceptional circumstances can emerge in which an article will need to be corrected, retracted, or in some cases, eliminated. Such actions will be conducted only after careful consideration on the part of the Nexo Revista Científica’s Editorial Team, to guarantee appropriate steps, following the norms recommended in COPE.

In such cases as these, the regime of norms and control mechanisms for scholarly communications has several principal rectification procedures in accordance with the type, seriousness, and the consequences of the detected error. These can be resolved by an announcement of errata or correction, a retraction, or in rare occasions, the elimination an article. The objective of this mechanism is that the changes be transparent and that they provide a guarantee to the integrity of the scholarly registry.  

Errata

An announcement of errata will be published when required to correct an error or omission committed by the journal after the publication of an article or essay whose error may affect the reputation of the authors or of the journal, but where the scholarly work remains unaffected.

All errors will be accompanied by a separate announcement, which provides clear details of the error and the changes which have been made to the document.

In these circumstances:

  • The article will be corrected.
  • A note will be added at the end of the article referring to the announcement of the errata.
  • An announcement of errata or correction will be published separately, in conjunction with the corrected version.
  • The document of errata or correction will be placed in the table of contents and with an individual DOI.

Corrections

A notice of correction will be made when an error or omission committed by the authors has occurred, which may affect the contents of the publication or the reputation of the authors or of the journal, but does not affect the scholarly integrity of the work.

All errors will be accompanied by a separate announcement, which will provide clear details regarding the error and the changes made within the document. In these circumstances:  

  • The article will be corrected.
  • In the article, a note will be placed at the end which refers to the correction.
  • An announcement of errata or correction will be made separately which will be linked to the corrected version of the article.
  • The announcement of errata or correction will be paged in the Table of Contents and will be provided an individual DOI.

Retractions

An announcement of retraction will be published when an important error invalidates the conclusions of an article, or when misconduct has occurred in the research or in the publication of the article. The authors can request a retraction of an article if their motives comply with the criteria given below.

A retraction will be considered:

  • If there is clear evidence that the findings of the article are not trustworthy, whether from misconduct (for example, fabrication of data or manipulation of images) or from error (for example, calculational or experimental flaw).
  • If the findings have been published elsewhere without adequate cross-reference, permission, or justification (for example, cases or redundant publication or duplicate publication).
  • If the publication constitutes plagiarism.
  • If there is existence of fraudulent authorship.
  • If there is proof of impropriety in peer review.
  • If there exist indications of ethical flaws in the research or infractions of professional ethical codes.

When the decision has been made to retract an article:

  • A watermark will be added to the published article stating, “article retracted”.
  • Before the title of the article, “Article retracted” will be placed [title of article]
  • A declaration of retraction of the article will be published separately, titled #Retraction: [title of article]”, that will be linked to the retracted article. This note will be signed by the General Editor of the journal.
  • The declaration of retraction will be paged in the Table of Contents and will be assigned an individual DOI.

Elimination of articles

An article will be eliminated in exceptional, grave circumstances that can not be resolved through a correction or a retraction.

This will occur only:

  • When the article is clearly defamatory, or it infringes on certain legal rights.
  • When the article is the subject of a judicial order.
  • When the article could provoke risks in public health and safety.  
  • In the case of an eliminated article, metadata (authorship and title) will be conserved, and the text will be substituted with a document that indicates the article has been removed for legal or other reasons.

Resubmission of Manuscripts Within the Same Institution

If a manuscript has been previously reviewed and rejected by a journal belonging to the same institution, the author may submit it to a second institutional journal only if:

  • A formal rejection has been received from the first journal.
  • The author has made substantial modifications to the content, structure, or focus of the article, if applicable.
  • It is explicitly declared, at the time of the new submission, that the manuscript was previously submitted to and rejected by another institutional journal, indicating its name and the outcome of the editorial process.

Policy on the Use of Artificial Intelligence Tools

Authors who have used artificial intelligence (AI) tools—such as ChatGPT, Gemini, or other generative platforms—during the preparation of the manuscript must explicitly disclose this usage. This statement must specify:

  • The name of the AI tool used.
  • The sections of the manuscript where the tool was applied.
  • The type of content generated or assisted by the AI.
  • The rationale for using these tools in the writing or analysis process of the article.

Furthermore, the AI tool used must be properly cited and included in the references section in accordance with the citation style adopted by the journal.

The use of AI does not exempt authors from their ethical and academic responsibility regarding the content of the manuscript, nor does it replace critical judgment, intellectual authorship, or the scientific analysis that should characterize any academic publication.

Charges for processing and publication of articles

No article processing charges are required for publication. The National University of Engineering in Managua, Nicaragua finances the publication costs of the papers.
