  5. Do MSc Project Perform literature search Select a topic Make a plan Write up Gather & analyse data Create Gantt chart Produce estimates Plan resources Decide objectives Develop Work Struct. Overview of Project Work Structure Source Ref: to be added

  6. Research Design • General sequence of steps in research design • Identify the research problem • Determine the purpose of research • Develop the theoretical framework • Define the research questions and/or hypotheses • Define the scope of the study • Decide on methodology • Define expected outcomes • Writing up J Hussey & R Hussey, Business Research (Palgrave, 1997), Ch. 5.

  7. Identifying the topic • Why this topic? • is it topical, timely? • is there a clear need for work in this area? • if so, who needs it, who will use it? • how will the world be a better place? • Where does expertise lie? • who can you talk to? • what can you read to find out more? • does this confirm the need for the research? • Is the proposed research novel? • How does the project relate to other work? • does it follow on sequentially from something? (eg extension of previous project) • does it apply similar approach to another project? • does it fill a gap in knowledge? • draw a “mind map” of the subject

  8. Generating a Research Idea #1 • Following questions can help to define a research focus including; • What does the research seek to find out? What questions does it aim to answer, or what hypothesis does it seek to test? • What areas of knowledge, subjects and disciplines will the research need to draw on? • What do we know already that is relevant? Where shall we need to add new knowledge or know how? • What are the likely sources for the required information? • What are the potentially useful ways of doing the research - the methodological options? • What limits must we set to the breadth and depth of the inquiry? • What obligations do we have to fulfil to the institution in which we are doing the research? E Orna w. G Stevens, Managing Information for Research (OU Press 1995), Ch. 2.

  9. Generating a Research Idea #2 • finding your research subject • brainstorming • ways of refining the topic • analogy - import ideas and procedures from a similar area • morphological analysis - methodical breakdown of key dimensions of general area of interest • mind maps - use network diagram to extend out from central concept • relevance trees - use hierarchical diagram to develop fine categories within research area • importance of literature review • to increase your knowledge of research area and methodologies • to scope, justify and decide feasibility of your proposed work • to develop critical appraisal and ability to synthesize • consider purpose, conduct, findings, strengths and weaknesses of the studies you read

  10. Defining Research: problems/questions identifying a research problem developing research questions 1. read literature, identify gaps 1. state purpose of research 2. formulate specific questions or hypotheses 2. generate list of interesting questions N 6. does suitable problem exist? Y N 3. are they interesting or important? 3. questions already answered in literature? Y Y 5. have questions been answered already? Y N 5. eliminate impractical questions N 4. test feasibility 4. survey relevant literature to next stage in research design to next stage in research design J Hussey & R Hussey, Business Research (Palgrave, 1997), Ch. 5.

  11. ‘the role of information products and information presentation in organizations’ organizational policy - strategic objectives - corporate planning how organizations make decisions on information products information resource management people involved in information products - decision makers - professional specialists organizational information products - how they are used - medium of production technology for information products - DTP - databases - electronic publishing - document management training management of information products - writing - design - editing - typesetting - production - budget monitoring and evaluation of information products E Orna w. G Stevens, Managing Information for Research (OU Press 1995), Ch. 2. An Example -- Mind Map

  12. Literature Survey • Literature search • a methodical search of published sources of information to identify items relevant to a particular need, for instance; • Topic selection, Find specific project information • Discover structure of information in a particular subject, etc. • But remember to • Define your initial topic, scope, content and parameters for your own work first • Decide on what sort of relevant information to your project • range of sources - eg, reference works, books and articles, government publications, theses, conference proceedings, standards and statistics, directories, company and market reports… • Structure how you get it • decide on a search order, allow enough time, keep detailed records • identify keywords for searching, use computerized databases and Internet, but narrow your search first • Keep notes of references on index cards or computer

  13. Document/Start Search statement Read/Store Modify Information Sources Evaluate Search Strategy SEARCH Searching Cycle

  23. extracting information from sources - an exhaustive process use key topics as ‘hooks’ for searching and storing making notes make accurate note of bibliographic details of item at top of notes about any item, put key topic(s) prominently don’t copy large chunks of text, but do note page no. of any quotations you might use which vehicles to use for notes? Cards, loose leaf, notebooks? If notebooks, number them and number pages. storing information - key decisions what containers to use how to arrange items in containers like with like (need to label the containers by key topic) in sequence (need to number items as they come in) whether to create records of the items you store probably yes if no, items must be clearly labelled, and you will need an index into them by topic (etc) Storing information E Orna w. G Stevens, Managing Information for Research (OU Press 1995), Ch. 3.

  24. Software: Endnote

  25. Evaluating your Search Results • Ask yourself a number of questions; • relevant to your needs? • useful for the problem in hand? • date of publication appropriate? • obtainable? • level of information correct? • Too simple/advanced? • Is this a new information or do you know this already?

  26. Searching your information • Key considerations for indexing • decide what are the key topics • put them on index cards or use reference database software (Endnote) • use them as hooks to fish for information • put main topics on notes you make and on items you photocopy. • decide how to store your information - in number sequence or by main topic • set up an index - use cards from 2 or make back-of-book index to notebooks. • Searching your information • look up the cards for topics you want. • go from there to information store, and take out relevant items E Orna w. G Stevens, Managing Information for Research (OU Press 1995), Ch. 3.

  27. Literature Review • Definition • A story or narrative, which documents the previous research that is relevant to your own research area • The literature review essentially “sets the scene” and prepares the reader for your own contribution • The literature review usually occurs as chapter 2 in your thesis • But other sections of your thesis are likely to contain references to material considered in the literature review • Also the literature review is also an opportunity to learn more about the subject area you are researching • Purpose • knowledge of current literature and your own reading • present it thematically or in an order that relates to the rest of the project structure • identify trends, gaps etc in the literature • analyse, evaluate and otherwise demonstrate that you have understood what you have read • ALWAYS check your project guidelines

  28. Planning the Literature Review #1 Planning the literature review Set aside enough time to find, read and review a given publication. 75% of the literature review can be done in one session The other 25% may be ongoing as your understanding, knowledge and research skills develop Identify the main areas of the literature to be covered Make up a “shopping-list” of these areas so you know what you are looking for

  29. Planning the Literature Review #2 Find relevant publications Always follow the literature search cycle Remember to find 10 relevant publications you may have to read over 30 Thus you need to adhere to Find, read and record relevant literature Record the title of each publication Record the source (e.g. reference or a web-page) Make a brief note about the relevance of the publication

  30. Structure the literature that you have reviewed You could even use a table with appropriate categories Start by drawing a “concept map” or an overall plan of the literature review chapter Identify the main areas of the literature This will include the “parent” or main discipline and the context of your research The main areas will be the main sections in the literature chapter Identify relevant sub-areas to be highlighted Sub-divide the main literature areas into smaller sections These sections will be the sub-sections within the main sections of the literature chapter Structuring your Review #1

  31. Section 2.1 (introduction) Introduce your own research topic and explain what literature areas need to be reviewed Briefly present your concept map or plan to show the reader how the literature review is logically structured Section 2.2 to 2.x Address each of the main areas of the concept map or plan Try to move towards specific discussion of each area and identify what is already known and what is not known Section 2.x (final section) End by stating your own research challenge/question or any hypothesis Structuring your Review #2 Structuring the literature review

  32. Structuring your Review #3 Different literature review structures can be used including; The ‘funnel’ approach: from broad to narrow focus, from main areas/issues to detail from periphery to centre of research issue The ‘family tree’ approach: different levels of knowledge at each level: various options/theories/issues Time line Concept map 2.2 2.3 2.2 2.2.1 2.2.2 2.2.3 Writing the literature review

  33. Guidelines #1 The literature review chapter should not be standalone but relates to other chapters Ensure that the literature review chapter is closely linked to your study Mention your research topic up-front Then proceed to identify the main areas that will drive the literature review Show how your study is related to previous work (e.g. extends, fills gap, applies in different contexts, etc.) Use the literature review chapter to develop your own research framework or research model Use the literature review chapter to help shape subsequent chapters in your thesis Often to highlight the gap including research problem that your project is to focus on

  34. Guidelines #2 • Try to review topics rather than articles • GOOD: reviewing topics • “Absenteeism has been defined in three ways: • genuine absences through illness [1] • voluntary non-attendance e.g. skiving [2] • frequent absences due to mental or physical health problems [3]” • NOT AS GOOD: reviewing articles • “[1] says voluntary absences are due to illness. [2] suggests some absences are simply due to non-attendance e.g. skiving. [3] did a study and found that frequent absences are caused by mental or physical health problems ”
