Producing an information leaflet to help patients access high quality drug information on the Internet: a local study     

Coleman B 《Health information and libraries journal》2003,20(3):160-171

Objectives: To develop a patient information leaflet (PIL) to help local patients meet their drug information needs using the Internet, and to perform a preliminary evaluation of this tool. Methods: Development—a cross‐sectional survey of the drug information needs of local patients using a semi‐structured questionnaire; assessment of websites offering free, consumer‐orientated medicines information using set criteria; identification of consensus criteria to evaluate the quality of health‐related on‐line information; evaluation—views on a draft patient information leaflet from a focus group. Results: Those surveyed felt that being directed to high‐quality websites and being provided with assessment criteria for on‐line information would be useful. The three websites fulfilling most of the set quality criteria were Surgery Door ( www.surgerydoor.co.uk ), InteliHealth ( www.intelihealth.com ) and medline plus ( www.nlm.nih.gov/medlineplus ). The six most frequently cited assessment criteria were currency, authorship, commerciality, relevance, links and attribution. A draft leaflet was constructed listing the above three websites and six criteria along with tips on how to search the Internet effectively. A focus group reacted favourably. Conclusion: The Internet is a source of drug information—an information leaflet may help to guide local patients through its variable information quality.  相似文献   

The effect of two different 18-week walking programmes on aerobic fitness, selected blood lipids and factor XIIa

Forty-nine previously sedentary or low active individuals aged 40-71 years were allocated to three groups. The long walking group participated in an 18-week walking programme which consisted of walks lasting 20-40 min; the repetitive short walking group completed walks of between 10 and 15 min, up to three times a day, with no less than 120 min between each walk; and the control group maintained their low level of activity. Both walking programmes began at a prescribed 60 min x week(-1), which increased steadily up to 200 min x week(-1) by week 12. During the study, the long walking group walked for an estimated 2514 min (139 min x week(-1)), expending an estimated 67.5 MJ (3.72 MJ x week(-1)) at an estimated 73% of their age-predicted maximum heart rate and 68% of their estimated VO2max. The repetitive short walking group walked for an estimated 2476 min (135 min x week(-1)), expending an estimated 58.5 MJ (3.17 MJ x week(-1)) at an estimated 71% of their age-predicted maximum heart rate and 65% of their estimated VO2max. The results showed a statistically significant reduction in heart rate during a standardized step test (pre- vs post-intervention) in both walking groups, indicating an improvement in aerobic fitness, although the control group showed a higher average heart rate during the post-intervention test, indicating reduced fitness. When compared with the male subjects pre-intervention, the females possessed more favourable levels of high-density lipoprotein (HDL) cholesterol (P< 0.001), apolipoprotein (apo) AI (P < 0.001) and ratios of total cholesterol:HDL cholesterol (P< 0.02) and low-density lipoprotein (LDL) cholesterol: HDL cholesterol (P< 0.02). Compared with the controls post-intervention, the walking groups showed no statistically significant changes in total cholesterol, LDL cholesterol, HDL cholesterol, apo AI, apo AII, apo B, or the ratios of total cholesterol: HDL cholesterol, LDL cholesterol: HDL cholesterol, apo AI: apo B or apo AI: apo AII (P > 0.05). Relative to the walking groups, factor XIIa increased in the control group (P < 0.05). We conclude that, although both walking programmes appeared to improve aerobic fitness, there was no evidence of improvements in the blood lipids or associated apolipoproteins of the walking groups. Further analysis indicated that this apparent lack of change may have been related to the subjects' relatively good pre-intervention blood lipid profiles, which restricted the potential for change. The implications of the observed changes in the coagulation/fibrinolytic factors remain unclear.  相似文献

Science in Action: How Middle School Students Are Changing Their World Through STEM Service-Learning Projects     

Jane L. Newman  John Dantzler  April N. Coleman 《理论付诸实践》2015,54(1):47-54

The purpose of Science in Action (SIA) was to examine the relationship between implementing quality science, technology, engineering, and math (STEM) service-learning (SL) projects and the effect on students' academic engagement in middle school science, civic responsibility, and resilience to at-risk behaviors. The innovative project funded by the Corporation for National and Community Service (CNCS) included 6,000+ middle school at-risk students (eligible for at least 50% free or reduced-cost lunch), 126 science teachers who integrated STEM problem-based SL pedagogy into science instruction to teach students to solve real problems in schools and communities. The project involved 20 schools and communities with assistance from 120 community partners. Participants completed pre- and post-SL surveys on academic engagement, civic responsibility, and resilience; qualitative data were collected from journals, interviews, focus groups, observations, and field notes. Results highlight exemplary SL projects that demonstrated increased student academic engagement and achievement for students living in high poverty areas with potential at-risk behavior. Implications for future research and educational practices are discussed.  相似文献

The how's and why's of biological change: How learners neglect physical mechanisms in their search for meaning     

Eleanor Abrams  Sherry Southerland 《International Journal of Science Education》2013,35(12):1271-1281

This study describes the trends in students' explanations of biological change in organisms. A total of 96 student volunteers (8 students from each of 2nd, 5th, 8th, and 12th grades from 3 localities) were interviewed individually and each student was presented a series of graphics depicting natural phenomena. Students' explanations to questions of how something occurred were assigned to one of three categories (responses addressing how something occurred, why something occurred, and 'I don't know'). While the number of responses in each category was roughly equivalent in prominence across grade levels, the majority of students were unable to offer a causal explanation of how a phenomena occurred. An unexpected phenomenon was the students' predilection to redirect the interview question so they could answer them. If asked a how question, as they were in every interview instance, 32% the students answered with a 'why' response. The way biology is taught, the structure of biology or/and how we learn it could shed some light into this phenomenon and has implications for science educators.  相似文献

A study of results overlap and uniqueness among major Web search engines     

Amanda Spink  Bernard J. Jansen  Chris Blakely  Sherry Koshman 《Information processing & management》2006

The performance and capabilities of Web search engines is an important and significant area of research. Millions of people world wide use Web search engines very day. This paper reports the results of a major study examining the overlap among results retrieved by multiple Web search engines for a large set of more than 10,000 queries. Previous smaller studies have discussed a lack of overlap in results returned by Web search engines for the same queries. The goal of the current study was to conduct a large-scale study to measure the overlap of search results on the first result page (both non-sponsored and sponsored) across the four most popular Web search engines, at specific points in time using a large number of queries. The Web search engines included in the study were MSN Search, Google, Yahoo! and Ask Jeeves. Our study then compares these results with the first page results retrieved for the same queries by the metasearch engine Dogpile.com. Two sets of randomly selected user-entered queries, one set was 10,316 queries and the other 12,570 queries, from Infospace’s Dogpile.com search engine (the first set was from Dogpile, the second was from across the Infospace Network of search properties were submitted to the four single Web search engines). Findings show that the percent of total results unique to only one of the four Web search engines was 84.9%, shared by two of the three Web search engines was 11.4%, shared by three of the Web search engines was 2.6%, and shared by all four Web search engines was 1.1%. This small degree of overlap shows the significant difference in the way major Web search engines retrieve and rank results in response to given queries. Results point to the value of metasearch engines in Web retrieval to overcome the biases of individual search engines.  相似文献
