Life Table Guidelines

This manuscript provides guidelines for writing an undergraduate scientific paper on survivorship. Covers paper organization, abstract, introduction, methods, results, discussion, and literature cited sections. Offers tips on proper formatting, word choice, and data presentation. The document explains the importance of studying survivorship, outlines data collection methods, statistical analyses, and result interpretation. It also discusses gender and geographic differences in life expectancy based on hypotheses and previous studies. The text includes examples and suggestions for improving the study and its practical implications for scientists.

  1. Life Table Guidelines LIFE TABLE MANUSCRIPTS FEBRUARY 15, 2010

  2. Due Dates • Rough draft due March 1 (in lab) • 50 points • Final draft due March 15 (in lab) • 100 points • Must hand in a hard copy

  3. A great information source http://www.jyi.org/resources/320/Guide%20to%20Science%20Writing.pdf Guide to undergraduate scientific writing (pg 7-38)

  4. How publishing works • Write (or coauthor) a paper • Anonymous reviewers give feedback • Reviewers give suggestions to editors • Editors have the final say • Process can take months

  5. Paper organization Abstract Introduction Methods Results Discussion Literature Cited

  6. Abstract • Less than 500 words, generally 200-300 • Summarizes • Why/how research was conducted • What major results and conclusions were • Don’t cite references • Format (1-2 sentences each) • Idea 1: Problem to be investigated • Idea 2: Purpose of study • Idea 3: Methods • Idea 4: Results • Idea 5: Interpretations/conclusions

  7. Introduction • What is survivorship/why do we study it? • How has survivorship been studied before? • Use previous research-anthropology journals? • Outline the two populations • What are your hypotheses?

  8. Methods • Where/when data were collected • What information did you collect? What data were given? • Information you got from life table • What statistical analyses did you perform? • What program you used to calculate

  9. Results • Results of K-S test for each hypothesis • Kolmogorov-Smirnov two sample test, D [maximum deviation] =0.40, P<0.05; Table 1 • Do not include entire life table • Include tables and figures • I found Bloomington-Normal males and Bloomington-Normal females did not differ in life expectancy (Table 1). • No data interpretation

  10. Discussion • Interpret all 4 hypotheses • Which do you have evidence for/which do you fail to reject? • Why might there be gender differences or geographic differences? • Do your results agree with previous studies? • Likely sources of error influencing results • How can you improve study (real suggestions) • Why is this information useful-how can scientists use it? • Give specific interpretation, don’t be too broad

  11. Literature cited, formatting • Use guidelines from Lab 1 • In text citations • Jonas (2008) found… • Age-specific mortality does not differ…(Jonas 2008). • 3 or more authors= Jonas et al. (2008) says… • Formatting • Title page (pg 100) • Running head • Tables and figures • Literature cited

  12. Figures/tables • Make sure lines are distinguishable in B&W • Proper formatting (look in appendix) • Use the journal Ecology guidelines you printed at the beginning of the semester

  13. Word choice • Be precise • Analyze vs. evaluate vs. look at • Do not use adjectives • Data are plural • Do not start sentences with “There”
