The Philippine Journal of Science (Philipp J Sci) is a peer-reviewed journal in English that publishes reports of original research in the natural and applied sciences, engineering, mathematics, and social sciences. It also publishes invited reviews and viewpoints on timely subjects. This guide must be followed carefully in submitting a manuscript. Authors are also advised to consult a recent issue of the new PJS for current format and style.

Submitted manuscripts should not have been published or submitted elsewhere. Authors are responsible for obtaining permission from the original publisher to reproduce or modify tables and figures from previous publications. The Journal has no page charges. Ten (10) copies of reprints and an electronic copy are given free. Authors will be asked to sign a Transfer of Copyright form when the manuscript is accepted for publication.

In principle, reviews and viewpoints are written and submitted on the invitation of a member of the Editorial Board, although the Editors would also welcome suggestions. Proposals for review articles (approximately 500–1000 words) should be sent to the Editor-in-Chief for further reviewing.

All submitted papers are subject to a refereeing process.

All submissions shall include the following as attachments (in pdf format):
(a) Cover letter from the corresponding author explaining why their manuscript satisfies the Journal publication criteria of originality, merit, scientific novelty and significance.
(b) Full manuscript with figures and tables.
(c) List of five (5) possible reviewers with complete contact information (full name with title, affiliation, telephone number and e-mail address).

Incomplete submissions will not be reviewed.

Type manuscripts on one side of page, and double-spaced throughout the title page, abstract, text, references, tables, figure legends, etc. Lettering in Arial and 12-point font is preferable. Number all pages consecutively on top right corner, including those carrying tables, figure legends, and figures. Leave at least 2.5-cm margin on all sides. Each page must have line numbers. Do not use footnotes in the text. Ancillary information should appear in the text set off in parenthesis. Equations and formulas set off from the text should be typed in quadruple spacing and should be numbered. All measurements should be given in metric units. Observe clarity and conciseness in writing. Spelling should be according to the Webster Unabridged Dictionary. Limit the number of pages for research manuscript to 30 pages (10 printed pages).

The following abbreviations are used: h, min, s, yr, mo, wk, km, m, cm, mm, kg, g, mg, mL, etc. without periods. Abbreviate units of measure when used only with numerals. Use L for liter and % instead of percent. Designate temperature as in 27o C. For names of months, use three letters without the period as “Jan, Mar, Apr, Jul,” etc. Symbols, abbreviations, and acronyms should be defined when they are used first. Numbers: write out one to nine unless a measurement (e.g., two species, 3 cm, 4 yr). Day, month, and year are written as “25 Dec 1998.”
Novel or important findings warranting immediate publication but which cannot be justified as full-length articles can be published as research note/short communication. It should contain the same sections as full-length article and must not exceed 4 printed pages.


Manuscript format

Manuscript format

Title page (page 1) includes the title, running head, name of each author, addresses, and key words. The title should not exceed 250 characters, without active verbs, abbreviations, and punctuation marks. Avoid waste words such as “Studies on,” “Investigations on,” and “Observations on.” They are useless for indexing purposes. Main title-subtitle arrangement with Roman numeral, hanging title using a colon, and “question” titles are not acceptable. The running head should have no more than 50 characters and spaces. It is an abridged title suitable at the top of the printed page. Write the full name of each author. Give the full postal address, phone number, and e-mail address of the corresponding author to whom inquiries regarding the paper should be directed. On the bottom of the page, list up to six key words that reflect the content of the paper arranged alphabetically.

Abstract should occupy page 2 of the manuscript and written in one paragraph not to exceed 300 words. It should summarize the background and scope of the work, the principal results, and note the implications of these results or main conclusions. References and acronyms should be avoided. Since the abstract will be published separately by indexing services, it should concisely capture the basic content of the paper and be understandable without the text.

Text. The text starts on page 3. It includes the introduction, materials and methods used, results and discussion, and conclusion. They may be written as headings of separate sections or as an integrated text with appropriate headings suitable to the discipline. Headings and subheadings should be aligned to the left of the page and set in bold face and italics. An Introduction should describe the paper’s background and provide the rationale for the present study. Cite only those references that will provide the most relevant background rather than an exhaustive review of the topic. Methods should be described concisely and clearly to allow experiments to be repeated. For commonly used methods, a simple reference is sufficient. Avoid references that are not readily accessible. In Results, present data in only one of the following: text, table, or figure. Results should preferably have no more than five illustrations (tables and/or figures). Do not use tables or figures to present data that can be more concisely stated in the text. Discussion should interpret results in relation to previously published work. Do not repeat results or reiterate the introduction. Discussion should incorporate summary of conclusions. Literature citations should be selective, not to exceed 30 references for a research paper. Avoid citing gray literature or references not accessible through indexes or obtainable via regular library channels. Cite references in the text as follows: single author, White (1998) or (White 1998); two authors, White & Gray (1998) or (White & Gray 1998); more than two authors, Green et al. (1998) or (Green et al. 1998). Cite multiple references in chronological order (e.g., White & Gray 1990, Green 1992, Brown 1994, 1996). Do not cite unpublished work. Note that most of the abstract, methods, and results will be in the past tense, whereas most of the introduction, some of the discussion, and all conclusions will be in the present tense.

Acknowledgments should be brief and are placed under a separate heading immediately before References. Acknowledge any financial support for the work being published and personal assistance.

Personal communication should appear only in text parenthetically with the names of persons who supplied the information. They should not be listed in the References section.
Authors are urged to check references with special care that all references in the text appear at the end of the paper and vice versa, and that the names and dates are consistent as no editorial responsibility can be taken for their accuracy.

Tables. Type each table on a separate sheet. Never use vertical lines to separate columns. Prepare tables so that compared data read down, not across. Columns that show no significant variations should be omitted. Do not use tables for word lists. Titles should be clear, and column headings should be brief with units of measurements in parenthesis. Symbols and abbreviations should be defined below the table. Indicate table footnotes with a, b, c, etc. Do not present the same data in both graphical and tabular form. Tables should be self-explanatory or understandable without reference to the text.

Figure legends. Each figure should have a legend or caption typed on a separate sheet and should be self-explanatory. Figure legends should be in lowercase print-type, except for the first letter of first word. Abbreviations and symbols on figures should be defined in the legend. Figures include line drawings, photographs, and computer plots. They should be clear. Magnification of figures if needed should be given by scale. The size should not exceed a full manuscript page. Glossy prints of photographs should be sent mounted on regular bond paper, with lettering about 3 mm high. Write lightly with a soft pencil on the back or margin of figures, or use self-adhesive label, indicating the figure number and name of lead author. For guidance in the preparation of figures and manuscripts in general, authors are urged to refer to a good style manual, such as Robert Day’s How to write and publish a scientific paper, 4th ed. (1994) or The Chicago Manual of Style, 14th ed. (1993).
