Using transparency to increase awareness of chemical hazards.pptx Presentation Transcript

  • 1. Miriam Weil, MPH, ScD Work Environment Policy UMASS Lowell *Funding for this project was provided by NIOSH through the Harvard ERC and by the National Science Foundation  UMASS  Lowell  12/12/2011  
  • 2. Research  Ques+on   —  How can the internet help provide timely and useful health and safety information to people working with chemicals around academic laboratories? —  Hypothesis: For web-based chemical hazard information to be useful to researchers and workers at universities, it must be embedded so that action can be taken to reduce or prevent exposures.UMASS  Lowell  12/12/2011  
  • 3. What is Embeddedness?  —  Three elements determine whether a message is “embedded” in the users’ decision-making process:— Relevance: pertinent to user decisions.— Compatibility: with the user’s language and ‘socioeconomic’ or workplace culture.— Accessibility : easily found and consistent with the conventional patterns for finding information.—  Source: Fung Graham and Weil, 2007 3  
  • 4. Par+cipants     — Subjects: — Students (17) — Laboratory Staff (18) — Sites: — UMASS Lowell —  Harvard UniversityUMASS  Lowell  12/12/2011  
  • 5. Method:  Exercise  Format  Four parts to the experiment:1. Pre-test- Background questions2. Ethylene Glycol hypothetical question3. Acetonitrile hypothetical question4. Exit interview For 2 and 3 : Rate the relevance, compatibility, accessibility of each website towards pursuing the problem using a 5 point rating scale: where 1 is worst and 5 is best 5  
  • 6. Exercise  Format   Rate the relevance, compatibility, accessibility of each website towards pursuing the problem using the following rating scale: —  1 Disagree strongly —  2 Disagree —  3 Neither agree nor disagree —  4 Agree —  5 Agree stronglyUMASS  Lowell  12/12/2011

  • 10. The  Google  Effect    — Google is the default.— May not find best information.— Lab culture requires speed.— Miss other valuable sites   10  
  • 11. Findings/Conclusions  — Criteria  rankings  influenced  favorable   choices.    — ATSDR,  NJ  and  ICSC  rated  highly.  — The  internet  can  provide  helpful  and   useful  informa+on.  — Chemical  safety  sites  require  useful   content  and  a  high  Google  ranking   11
