Objectives:Current literature recommends online research guides as an easy and effective tool to promote LGBTQ+ health information to both health care providers and the public. This cross-sectional study was designed to determine how extensive LGBTQ+ health guides are among hospital and academic libraries and which features are most prevalent.Methods:In order to locate LGBTQ+ health guides for content analysis, we searched for guides on the websites of libraries belonging to the Association of Academic Health Sciences Libraries (AAHSL) and the Canadian Association of Research Libraries (CARL). Additionally, we searched the Springshare interface for LibGuides with the word “health” and either “LGBT” or “transgender.” Content analysis was performed to identify major characteristics of the located guides, including target audience and the information type provided.Results:LGBTQ+ research guides were identified for 74 libraries. Of these, 5 were hospital libraries, and the rest were academic libraries. Of 158 AAHSL member libraries, 48 (30.4%) had LGBTQ+ guides on their websites. Nearly all guides (95.9%) provided general LGBTQ+ health information, and a large majority (87.8%) also had information resources for transgender health. Smaller percentages of guides contained information on HIV/AIDS (48.6%) and women''s health (16.2%).Conclusions:Even though literature recommends creating LGBTQ+ health guides, most health sciences libraries are missing an opportunity by not developing and maintaining these guides. Further research may be needed to determine the usage and usefulness of existing guides and to better identify barriers preventing libraries from creating guides. 相似文献

The experimental investigation of the laws governing the excitation of x-rays by electron impact appears to be near completion. However, the existence of the proton, with its mass of 1,846 times that of the electron, provides the possibility of introducing anew variable—the mass—into collision experiments. Previous investigations have led to inconclusive results except that it is known that when fast α-particles fall on an element, its characteristic x-ray spectrum is excited.In the writer's experiments, a mass spectrograph is used to bring either protons or electrons, of same energy in the range from 15 kv. to 25 kv., onto a copper target. The arrangement eliminates several known sources of error. X-radiation produced passed into an argon filled Geiger counter.The procedure was to compare two currents: (1) the current composing an electron beam just intense enough to produce detectable x-rays; and (2) that composing the strongest proton beam which certainly produced less radiation.The ratio of these currents is a minimum value for p, the ratio of the efficiencies for excitation of electrons and protons respectively.The results were that (1) no radiation from proton impacts was observed, (2) the minimum value of p from three sets of experiments was 740; 237,000; and 6,400.In view of the directness of the experiment, the order of magnitude of the highest figure is presented as the result, i.e. ? = 105. This may be compared with (.Wave mechanical considerations of impact processes indicate that radiation should be produced by proton impacts of energy greater than the critical energy (for copper, 8.86 kv.) but intensity formulas have not been derived.If they can be derived the present results offer the possibility of checking the wave mechanics of impact processes. 相似文献

A comparison between conventional and live television methods of demonstrating an exercise in dental technology indicated that they were equally effective as judged by grading of students' work. Students' comments suggested that the unedited television method was recieved less favourably. Their comments form a basis for discussion regarding the development of edited self‐access cassettes or cartridges in preference to unedited television demonstrations in real time. 相似文献

I seek here to explain and elaborate on how and why Paulo Freire’s work has significance for educators in today’s ‘affluent’ west, not least in reminding us powerfully of core critical and celebratory values at a time when many teachers, and not only of English, feel under huge pressure – a pressure that in fact verges on the oppressive. My focus here is on native language teaching and learning – English, in effect – thus echoing Freire’s concern for critical literacy and pedagogy and how these may relate constructively to fundamentally Romantic traditions of English pedagogy. 相似文献
