Editor's Notes
- Hi, My name is ……… and I’m one of the Science Librarians at the Barry J Marshall Library.
- Aim of this library workshop is to support you in the research requirements of your two major assessments for this unit, specifically in identifying the research evidence in support of your RCT Research proposal.
- This workshop will focus on developing these research skills so as to support you in answering the questions about your risk factor for your promotional review. Be able to identify and effectively search a range of medical/health resources to locate information relevant to addressing each of the review requirements. Construct an effective search strategy Know what types of resources are available and how to search them Understand that search results will deliver different levels of evidence and focus their search strategy on high level, synthesised sources of evidence. Understand the different levels of hierarchies of evidence available to them; Have strategies for limiting to and evaluating these
- Before you start any search, it’s important to spend a little bit of time: Breaking down your search topic identifying the core concepts important to your research, Coming up with other keywords/terms used to describe your topic and thinking about how you combine them. Other terms you could add: Nutrition Obesity For impact: Do you know of any medical terms that could help: Epidemilogy – study of the distribution and determinants of health related states or events Aetiology It is worth putting some thought into what your concepts are and how you might
- Who is familiar with the term Grey Literature and can tell me what it is? Often used to refer to government or non-government, organisation or agency sources of information (reports, data etc) that are gathered by them and that may not otherwise be able to be located in bibliographic databases which have as their greater focus published items such as books, articles and research… sometimes reports are captured in some databases. Can represent the most direct route to information about a specific population, especially in a country like Australia. Population health guide: Statistics, reports and website page: Explain what a subject guide is and what it is.. Direct to the guide and to search for their specific risk factor or topic of interest. Example: AIHW
- Site links to important sources of grey literature.
- Explain Boolean and Brackets. Explain that you use broad terms at this early stage, can increase specificity if retrieving too many results. Would not necessarily use all of the terms developed, you are starting a process of seeing which work best in the different resources we will search. ASK STUDENTS TO SPEND SOME TIME DEFINING A EPIDEMIOLOGICAL TOPIC OF INTEREST TO YOU – Activity 1
