Editorial
Peer review: Double-blind peer review. The authors do not know the reviewers, and the reviewers do not know the authors. This model reduces the possibility for the authors to pressure the reviewers for results and reduces the chances for the reviewers to conceive favors for the authors.
Plagiarism: The Journal routinely screens article submissions for plagiarism, normally the journal screens the text using Grammarly or ProWritingAid (complementary methods may be used, such as an internet search on DuckDuck Go or Google)
Repository policy: Authors are permitted to post their work online (e.g., in institutional repositories or on their website) after the complete submission process and final publication of the original manuscript, and the authors are responsable by the informations that they present.
PEER-REVIEW PROCESS
All articles undergo thorough double-blind peer review. This involves a review by at least two independent reviewers.
The double-blind peer-review process
The double-blind peer review is an important part of the publication process. All submissions to Periódico Tchê Química are initially assessed by an Editor, who will decide whether they are suitable for peer review. As the reviewers are voluntary they must receive for evaluation only materials with good publishing potential. Therefore, the editor will filter the manuscripts that are not suitable to avoid the misuse of the time of the reviewers. This filter may include a request for the authors to improve the manuscript or a rejection.
If a member of the journal staff is present in the author list or has any other competing interest regarding a specific manuscript, another member of the Editorial Board will be assigned to assume responsibility for overseeing peer review. Submissions suitable for consideration will be sent for peer review by appropriate independent experts identified by the editor. The names of the authors are removed from the file to avoid their identification. The editor will decide based on the reports of the reviewers, and authors will receive a notification based on these reports along with the editorial decision on their manuscript. The authors should note that even in the light of one positive report, concerns raised by another reviewer may fundamentally undermine the study and result in the manuscript being rejected.
The practice of peer-review aims to ensure that only good science is published. It is an objective process at the heart of good scholarly publishing and is carried out by all reputable scientific journals. All referees play a vital role in maintaining the high standards Review Policy and all manuscripts are peer-reviewed following the procedure outlined below.
Initial manuscript evaluation
The Editor first evaluates all manuscripts to check their suitability to the AIM and SCOPE of the Journal, apart from critical issues like Plagiarism and Citation manipulation. It is rare, but an exceptional manuscript can be accepted at this stage. Manuscripts rejected at this stage are insufficiently original, have serious scientific flaws, have poor grammar or English language, or are outside the journal's aims and scope. Those that meet the minimum criteria are normally passed on to at least 2 experts for review. The image of the Publication Flow Chart provides a graphical representation of the publication process. Let us focus on the actions that start with the submission done by the author until the double-blind per-review moment.
Stages of the review process
The author starts the submission process by sending the cover letter file and the manuscript by e-mail; there are templates for the cover letter and the manuscript preparation available for download, so it is expected that at least the cover letter uses the template. The authors can recommend potential reviewers on the manuscript submission process. The editors will check to ensure no conflicts of interest before contacting those reviewers and will not consider those with competing interests. Reviewers are asked to declare any conflicts of interest. Authors could also enter the names of potential peer reviewers they wish to exclude from consideration in the peer review of their manuscript during the initial submission. The editorial team respects these requests as long as this does not interfere with the objective and thorough assessment of the submission;
After receiving the submission, the Editor will verify its content for completeness, scope, structure, plagiarism, and quality. When necessary, the submission fee will be charged at this point. From this initial desk review, the possible results are:
Rejection of the manuscript. In this scenario, the authors can submit the manuscript to another journal.
Return to the authors for improvements. The authors must resolve all the appointments made by the Editor prior to the return of the manuscript. A new desk review will be done.
Procced to double-blind peer review. At least two independent reviewers will be selected, normally by an editor, to evaluate the content of the manuscript. The reviewers will return their comments to the Editor. Based on the reviewer analysis, the Editor may approve the manuscript, request improvements, or reject the manuscript.
If the reviewers and editors approve the manuscript, it will proceed to publication.
Post Publication discussions and corrections. The Periódico Tchê Química follows the guidance from COPE regarding ethical concerns for published articles. Complaints and Appeal Editor in Chief e-mail at journal.tq@gmail.com is available for contact should the authors have an objection or disagreement pertaining to the publication process in The Periódico Tchê Química. Every complaint will be acknowledged and handled to resolve the issue accordingly. In addition, articles may be retracted for scientific or ethical reasons, which can be requested by the author(s) or the Editor. Articles found to be seriously flawed or violated ethical guidance from COPE will be retracted to correct the scientific record. The retracted article will be noticed on the website of the journal alongside information regarding the reason for the retraction.
Please take a moment to watch this instructional video regarding the publication procedures.
Type of Peer-Review
The Periódico Tchê Química employs double-blind peer-reviewing, where both the referee and author remain anonymous throughout the process.
Referees are asked to evaluate whether the manuscript is original; methodologically sound; follows appropriate ethical guidelines; has results clearly presented and supports the conclusions, and correctly references previous relevant work. Language correction is not part of the peer-review process, but referees may, if so wish, suggest modifications to the manuscript.
How long does the review process take?
The review processing time might take up to 90 from the date of receiving the paper. Should the referee's reports contradict one another or a report is unnecessarily delayed, a further expert opinion will be sought. The decision of the editor will be sent to the author with recommendations made by the referees, which usually include verbatim comments by the referees. Revised manuscripts might be returned to the initial referees, who may request another manuscript revision.
Final report
A final decision to accept or reject the manuscript will be sent to the author, and any recommendations made by the referees. It may include verbatim comments by the referees.
The Decision of the Editor is final
Referees advise the editor, who is responsible for accepting or rejecting the article.
Misconduct
Periódico Tchê Química will follow the COPE guidelines (CLICK HERE < https://publicationethics.org/guidance>) outlining how to deal with cases of suspected misconduct.
Research misconduct
All research involving humans (including human data and human material) and animals must have been carried out within an appropriate ethical framework (see our research involving animals - Animal Ethics Committees (A.E.C.s) and Ethics approval for research involving human participants, human material, or human data information). Suppose there is suspicion that research has not taken place within an appropriate ethical framework. In that case, the editor may reject a manuscript and may inform third parties, for example, author(s)' institution(s) and ethics committee(s). In cases of proven research misconduct involving published articles or where the scientific integrity of the article is significantly undermined, articles may be retracted.
INFORMATION TO REVIEWERS
Peer reviews are extremely important to the editorial process and quality of the journal. A well-done review is also important to guide authors in revising their work.
In case you have any conflicts of interest in reviewing a manuscript, please contact any of the editors of the Journal. The manuscript will be assigned to another reviewer.
Conflicts of interest may include:
Personal conflict; e.g., a personal relationship with the author or institution that could interfere with you providing an unbiased review. While Periódico Tchê Química removes identifying information from the manuscript, the referee may be able to discern the author's identity in other ways.
Financial conflict, or holding a financial interest in a product, company, or organization discussed in the manuscript; e.g., holding stock in a drug company, or consulting with a particular health care organization.
Intellectual conflict or holding a strong interest in seeing the manuscript published or not published.
We encourage you to review the Committee on Publication Ethics (COPE) document on Ethical Guidelines for Peer Reviewers (CLICK HERE). If you are new to reviewing, check COPE's resource, What to Consider When Asked to Peer Review a Manuscript.
Content of the Review.
Your review should focus on the content of the manuscript, rather than editing it for grammar or punctuation or rewriting and reorganizing it (the journal has a team for that).
Periódico Tchê Química is interested in manuscripts that reflect the 'state of the science' and, importantly, include practical application. Consider if the content is accurate and up to date. Is there anything the author didn't include but should have?
You may want to check into sources cited by the author that are unfamiliar to you. Are the citations and references appropriate, fairly recent (most within 10 years), and from credible sources? Is the material accurately represented, or is it plagiarized? (The editors of Periódico Tchê Química run all submissions through plagiarism detection software before sending it to the reviewers, but if you notice something, please indicate that.) Authors should be citing primary sources – that is, from the original research article or database.
If you recommend that the manuscript be revised, you must provide detailed comments to guide the author on the review form in the comments section. Note what should they do to fix the paper to make it acceptable. Should they add details or additional content, replace sources? If you are recommending that the manuscript be rejected, your narrative should indicate why, but do not spend unnecessary time on a fatally flawed manuscript.
The tone of the Review.
Please write your narrative in a nonjudgmental style. Begin with the positives if possible. If you believe the manuscript should be revised, please be encouraging and specific in your comments. Refrain from disparaging, critical remarks that aren't constructive.
PLEASE NOTE: All submitted reviews are confidential and are the property of PERIÓDICO TCHÊ QUÍMICA and may not be submitted for dissemination or publication elsewhere.
Manuscripts should be treated as confidential material. If you want to solicit the expertise of another colleague to review it, please contact any of the editors-in-chief before doing so. It is recommended that you keep a copy of your review narrative for three months.
If you have any questions, please don't hesitate to contact any of the editors-in-chief.
All manuscripts are peer-reviewed by at least two independent referees. The evaluation is based on the form indicated above. The review sheets will be sent to the author(s) anonymously.
Revised manuscripts
Manuscripts returned to authors for revision should be sent back to the editors within three months. The revised manuscript should be submitted to the same e-mail address by the author who originally submitted the article. The author should also answer the referees' comments, detailing changes made in the new version and, in case some of the referees' suggestions were not accepted, justifying the reason for this. After the submission has been checked by the editors, another e-mail will be sent with the final comments and suitable information.
Final version
As soon as all questions about referees' comments and the revision itself are solved, the editors will notify the author if the article was accepted or refused through an e-mail message. The editors of Periódico Tchê Química reserve the right to make small changes to the manuscript, if necessary, to adjust them to the rules of the Journal or improve the style, respecting naturally the content of the article. Whatever the nature of the manuscript, it should be original in terms of methodology, information, interpretation, or critique. Two referees will attest to the quality of the article.

3. THE MAIN TEXT PART OF THE MANUSCRIPT
The words Introduction, Review of Literature, Definitions (if any), Materials and Methods or Methodology, or Development, or Background, Results and Discussion of Findings, Conclusions must be written in capital letters, Arial, font size 12, left alignment, bold.
INTRODUCTION: The introduction must clearly state the problem, the reason for doing the work, the hypotheses or theoretical predictions under consideration, and the essential background. It should not contain equations or mathematical notation. A brief survey of the relevant literature so that a non-specialist reader could understand the significance of the presented results. A good introduction should ideally have 3-5 well-explained paragraphs and should finishing pointing out the AIM of the study.
MATERIALS AND METHODS OR METHODOLOGY, OR DEVELOPMENT: Provide sufficient details to the reader to understand how the study was performed. The technical description of methods should be given when such methods are new. It is generally recommended that the materials and methods should be written in the past tense, preferably in the passive voice. In this section, ethical approval, study dates, number of subjects, groups, evaluation criteria, exclusion criteria and statistical methods should be described sequentially. The following questions should be absolutely provided: the beginning, and termination dates of the study period; number of subjects/patients/experimental animals . enrolled in the study; has the approval of the ethics committee been obtained? Study design (prospective, retrospective or other); still additional features of the study design (cross-sectional) should be indicated. Apart from this, other types of study designs (randomized, double-blind, placebo-controlled or double-blind, parallel control.) should be revealed. Before you finish your manuscript, ask yourself the following questions about your Materials and Methods section to ensure that you have included all important information. Is there sufficient detail so that the experiments can be reproduced? Is there excess information that could be removed without affecting the interpretation of the results? Are all the appropriate controls mentioned? Are all appropriate citations included? Is the source of each reagent listed? The Materials and Methods section is a vital component of any manuscript. This section of the report gives a detailed account of the procedure that was followed in completing the experiment(s) discussed in the paper. Such an account is very important, not only so that the reader has a clear understanding of the experiment, but a well written Materials and Methods section also serves as a set of instructions for anyone desiring to replicate the study in the future. Considering the importance of "reproducible results" in science, it is very relevant why this second application is so vital. Some general rules for Methods sections are:
It should be clear from the Methods section how all of the data in the Results section were obtained;
The study system should be clearly described. In medicine, for example, researchers need to specify the number of study subjects; how, when, and where the subjects were recruited, and that the study obtained appropriate ‘informed consent’ documents; and what criteria subjects had to meet to be included in the study;
In most cases, the experiments should include appropriate controls or comparators. The conditions of the controls should be specified.
The outcomes of the study should be defined, and the outcome measures should be objectively validated.
The methods used to analyze the data must be statistically sound.
For qualitative studies, an established qualitative research method (e.g. grounded theory is often used in sociology) must be used as appropriate for the study question.
If the authors used a technique from a published study, they should include a citation and a summary of the procedure in the text. The method also needs to be appropriate for the present experiment.
All materials and instruments should be identified, including the supplier’s name and location.
The Methods section should not have information that belongs in another section (such as the Introduction or Results).
You may suggest if additional experiments would greatly improve the quality of the manuscript. Your suggestions should be in line with the study’s aims. Remember that almost any study could be strengthened by further experiments, so only suggest further work if you believe that the manuscript is not publishable without it.
RESULTS AND DISCUSSION OR FINDINGS: Results should be presented concisely. Also, point out the significance of the results, and place the results in the context of other work and theoretical background. The results and discussion sections are one of the challenging sections to write. It is important to plan this section carefully as it may contain a large amount of scientific data that needs to be presented clearly and concisely. The purpose of the Results section is to present the key results of your research. Results and discussions can either be combined into one section or organized as separate sections. Use subsections and subheadings to improve readability and clarity. Number all tables and figures with descriptive titles. Present your results as figures and tables and point the reader to relevant items while discussing the results. This section should highlight significant or interesting findings along with P values for statistical tests. Be sure to include negative results and highlight the potential limitations of the paper. The results and discussion section of your research paper should include the following: Findings; Comparison with prior studies; Limitations of your work; Casual arguments; Speculations; Deductive arguments.
CONCLUSION: Summarize the data discussed in the Results and Discussion or Findings section showing the relevance of the work and how different it is from other researches. Also, point out the benefits and improvements that can be observed to develop new science standards that can change something in the related field.
ACKNOWLEDGMENTS: (if any) These should be placed in a separate paragraph at the end of the text, immediately before the list of references. It may include funding information too.
REFERENCES: References should be cited in the text using the name-and-year system (Author, year) (APA FORMAT). Alternatively, the author's surname may be integrated into the text, followed by the year of publication in parentheses. Examples: Grasslands are regarded as important foraging areas for many insectivores in Europe, such as birds (Vichery, 2001; Barnet et al., 2004), bats (Guttinger, 1997) or amphibians and reptiles (Langton and Burton, 1997). However, the knowledge of the overall arthropod availability in such grasslands is scarce, since many studies about insect populations concentrate on extensive grasslands on poor, dry or wet soils include only few species or systematic groups (Ellgsen et al., 1997; Gibson et al., 1992; Hansel and Plachter, 2004; Manhart et al., 2004; Kruess and Tscharntke, 2002a, b; Wingerden et al., 1992; Sjodin, 2007a, b; Perner et al., 2005). Carbon dioxide produced by the combustion of biodiesel can be recycled by photosynthesis, thereby minimizing the impact of biodiesel combustion on the greenhouse effect (Korbitz, 1999; Agarwal and Das, 2001).
Cite only essential resources, avoid citing unpublished material. References to papers "in press" must mean that the article has been accepted for publication. At the end of the paper list references alphabetically by the last name of the first author. Please, list only those references that are cited in the text and prepare this list as an automatically numbered list. The word References with size 12, bold, capital letters, left alignment

The number of pictures (including graphs and diagrams) should not exceed 15 and should be submitted either in JPEG or PNG formats. All photographs, charts, and diagrams should be numbered consecutively (e.g., Figure 1, Figure 2, Figure 3,…..) in the order in which they are referred to in the text. The caption must appear below the figure (size 11, bold, italic) and should be sufficiently detailed to enable us to understand apart from the text. Explanation of lettering and symbols should be also given in the caption and only exceptionally in the figures. Figures should be of good quality. Scanned figures should be at a resolution of 800 dpi/bitmap for line graphs. Diagrams containing chemical structures should be of high graphical quality and always be of the same size so that they can be uniformly reduced. Figures should have a maximum width of one Journal column (8.5 cm) to be inserted on the body of the text so that they can be applied to the standards of the Journal. If the figures exceed 8.5 cm, they will be placed at the end of the article. Also, authors may be requested to submit each figure as an image file in one of the following formats: jpeg or png. For pictures, graphs, diagrams, and tables identical to material already published in the literature, authors should seek permission for publication from the companies or scientific societies holding the copyrights and send it to the editors of Periódico Tchê Química along with the final form of the manuscript
Important summarized information:
Upload the images either in JPEG or PNG formats. Poor quality and resolution figures will not be accepted. Pay attention when scanning or making print screen of an image. In these cases, the resolution is usually low and it becomes challenging to the reader to see the information of the figure;
Figures should be numbered consecutively, in Arabic numerals, according to the order in which they have been first cited in the text;
All information including numbers and symbols should be clear and of uniform size. The lettering for figures should be large enough to be legible either in the two or one column format;
Any details to point out a specific view like symbols, arrows, or letters used in photomicrographs should contrast with the background;
Titles and detailed explanations belong in the legends for illustrations not on the illustrations themselves.
When graphs, scatter-grams or histograms are submitted the numerical data on which they are based should also be supplied and clear enough.
The photographs and figures should be trimmed to remove all the unwanted areas. Also, if photographs of individuals are used, their pictures must be accompanied by written permission to use the photograph.
If a figure has been published elsewhere, acknowledge the source and submit written permission from the copyright holder to reproduce the material. A credit line should appear in the legend for such figures.
Legends for illustrations: When symbols, arrows, numbers, or letters are used to identify parts of the illustrations, identify and explain each one in the legend. Explain the internal scale (magnification) and identify the method of staining in photomicrographs when suitable;
The Journal reserves the right to crop, rotate, reduce, or enlarge the photographs to an acceptable size.
6. TABLES
Tables should be self-explanatory and should not duplicate textual material. They should be mentioned in the text, numbered consecutively (e.g., Table 1, Table 2, Table 3,....), and accompanied by a title at the top (size 11, bold, italic). Please insert all the tables in the text and do not enclose huge tables that cannot fit within the page margins. Other important considerations.
Tables with more than 15 columns and 30 rows are not acceptable.
Number tables, in Arabic numerals, consecutively in the order of their first citation in the text and supply a brief title for each.
Place explanatory matter in footnotes, not in the heading.
Explain in footnotes all non-standard abbreviations that are used in each table. If necessary, use symbols to explain and make all abbreviations clear to the reader.
Obtain permission for all fully borrowed, adapted, and modified tables and provide a credit line in the footnote.
Tables with their legends should be provided at the end of the text after the references. The tables along with their number should be cited at the relevant place in the text.
In the text, do not use Tab. For an abbreviation of a Table. Write Table 1, Table 2 instead of Tab.1, Tab.2;
7. MATHEMATICAL EXPRESSIONS
In general, minimize unusual typographical requirements, use solidus, built-up fractions. Avoid lengthy equations that will take several lines (possibly by defining the terms of the equation in separate displays). For drawing equations, please use the Equation Editor of Word, if possible. Make subscripts and superscripts clear. Display only those mathematical expressions that must be numbered for later reference or that need to be emphasized. The equations displayed should be consecutively numbered throughout the paper. The numbers should be placed in parentheses on the right of the equation, e.g. (Eq. 1).
8. SUPPLEMENTARY MATERIAL
Any Supplementary material (extra figures, tables, diagrams, appendix, abbreviations list) should be placed at the end of the manuscript and indicated as such. All supplementary material should also be cited in the text.
Editors, at any time of the editing process, may ask authors to split off part of the manuscript, presenting it as supplementary material.
Correction and Retraction
The Periódico Tchê Química assumes responsibility to seriously maintain the integrity and completeness of the scholarly record of our content for all end users. Therefore, changes to articles after they have been published online may only be made under the circumstances outlined below. The Periódico Tchê Química emphasizes the authority of articles after publication. Therefore, the journal policy is based on best practices in the academic publishing community. On December 25, 2022, the Periódico Tchê Química introduced an erratum template file.
An Erratum is a statement by the original paper's authors that briefly describes any correction(s) resulting from errors or omissions. In addition, any effects on the conclusions of the paper should be noted. The corrected article is not removed from the online journal, but notice of erratum is given. The erratum is made freely available to all readers and is linked to the corrected article.
A Retraction is a notice that the paper should not be regarded as part of the scientific literature. Retractions are issued if there is clear evidence that the findings are unreliable, this can be as a result of an honest error or misconduct; if the findings have previously been published elsewhere without proper referencing, permission, or justification; if the work was plagiarized; or if the work reports unethical research. To protect the integrity of the record, the retracted article is not removed from the online journal. However, a retraction notice is given, made freely available to all readers, and linked to the retracted article. The authors can publish retractions when they have discovered substantial scientific errors; in other cases, the Editors or Publisher may conclude that retraction is appropriate. In all cases, the retraction indicates the reason for the action and who is responsible for the decision. If a retraction is made without the unanimous agreement of the authors, that is also noted. The Publisher may redact or remove an article in rare and extreme cases involving legal infringement. Bibliographic information about the article will be retained to ensure the integrity of the scientific record.
A Publisher's Note notifies readers that an article has been corrected subsequent to publication. It is issued by the Publisher and is used in cases where typographical or production errors (which are the Publisher's fault) affect the integrity of the article metadata (such as title, author list or byline) or will significantly impact the readers' ability to comprehend the article. The original article is removed and replaced with a corrected version. Publisher's Notes are freely available to all readers. Minor errors that do not affect the integrity of the metadata or a reader's ability to understand an article and that do not involve a scientific error or omission will be corrected at the Publisher's discretion.
The original article is removed and replaced with a corrected version in such a case. The date the correction is made is noted on the corrected article. Authors should also be aware that an original article can only be removed and replaced with a corrected version less than one year after the original publication date. Corrections to an article with a publication date older than one year will only be documented by a Publisher's Note.

Guidelines for publication
General - Articles suitable for publication Periódico Tchê Química (PTQ) are those that cover the traditional fields of Chemistry, Biology, Physics, Mathematics, Pharmacy, Medicine, Engineering, Agronomical sciences, and Education in Science. Articles should conform to one of the categories below:
Original Articles (in Portuguese or
English): for communicating original research. Articles should follow the usual form of presentation, including the IMRAD structure (introduction, methodology, results, discussion, and conclusions) as appropriate for the work being submitted. They should have a maximum of 20 pages, including figures, tables, diagrams. All pages should be numbered following the template.
Review Articles (in Portuguese or
English):
for communicating progress in a specific field of Chemistry, Biology, Physics, Mathematics, Pharmacy, Medicine, Engineering, Agronomical sciences, and Education in Science, to provide a critical account of the state of the art from the point of view of the highly qualified and experienced specialist. They should have a maximum of 40 pages, including figures, tables, diagrams. All pages should be numbered following the template. Authors need to have publications in the field reviewed attesting their experience and qualification. Before submitting the manuscript, authors should send an e-mail to the editors with an abstract of the review and a letter explaining the relevance of the publication. The material will be examined by the editors and, once approved, authors will be requested to submit the full manuscript, according to PTQ guidelines.
Technical Notes (in Portuguese or
English): for communicating methods, validation of methods, techniques, equipment, and accessories developed in the author's laboratory or according to the professional experience of the authors in checking some situations at the site. They should have a maximum of 25 pages, including figures, tables, and diagrams. All pages should be numbered following the template.
Interviews (in Portuguese or
English): for communicating interviews linked to one of the subjects of the interest of Periódico Tchê Química. The interview should have a maximum of 20 questions or 15 pages. The person who is going to be interviewed does not necessarily need to be a researcher. It may be another person since the subject to be discussed shows relevance in the field of science. All pages should be numbered following the template.
Short Communications - Short Communications (in Portuguese or English): Short Communications are short papers that present original and significant material for rapid dissemination. For instance, Short Communication may focus on a particular aspect of a problem or a new finding that is expected to have a significant impact. Short articles include, but are not limited to the discovery or development of new materials, cutting-edge experiments, and theory, the novelty in simulation and modeling, elucidation of mechanisms. Short Communications are limited to 3000 words and are not subdivided. The paper should contain an abstract, main body, and references, and contain no more than 6 figures or tables, combined. The abstract is limited to 100 words.
Case Study - Case Study (in Portuguese or English): a case study research paper examines a person, place, event, phenomenon, or another type of subject of analysis to extrapolate key themes and results that help predict future trends, illuminate previously hidden issues that can be applied to practice, and/or provide a means for understanding an important research problem with greater clarity. A case study research paper usually examines a single subject of analysis, but case study papers can also be designed as a comparative investigation that shows relationships between two or more subjects. The methods used to study a case can rest within a quantitative, qualitative, or mixed-method investigative paradigm. A case study as a qualitative methodology is an exploration of a time- and space-bound phenomenon and requires much more from their authors who are acting as instruments within the inquiry process. In the case study methodology, a variety of methodological approaches may be employed to explain the complexity of the problem being studied. A case study research is defined as a qualitative approach in which the investigator explores a real-life, contemporary bounded system (a case) or multiple bound systems (cases) over time, through detailed, in-depth data collection involving multiple sources of information, and reports a case description and case themes. The unit of analysis in the case study might be multiple cases (a multisite study) or a single case (a within-site case study).
