Research Methodology IV BTech IT Cape Peninsula University (CPUT) Faculty of Informatics & Design (FID) Lecturer: Nhlanhla Mlitwa Research & Research Process …Units of analysis From individuals to groups Remember the difference between studying members of a criminal gang … and studying differences between big and small gangs – what are the units of analysis? You may also be studying an organisation or organisations: identify them according to specific characteristics Sometimes you are only interested – not on individuals but only in their actions: i.e. whether weddings are racially mixed or not, secular or religious, or simply interested on understanding the kissing habbits of drunk people You may also be studying artefacts such as: Books, songs, cars, computers, or other scientific discoveries. Each artefact could imply a set of other artefacts: i.e. “all books”; “all songs”, “all cars”,…etc Research & Research Process The Time Dimension Research over one or more phenomena - that is conducted at a specific point in time obviously produces results about that moment in time and often not about other times. This study is referred as Cross-Sectional. Exploratory & Descriptive studies are usually cross-sectional. Danger: Things about life in general, keep changing and generalising about life as a whole - based on a snapshot in time can be misleading. That is why some research studies called Longitudinal Studies are designed – to permit observations over extended continuous periods of time, i.e. every 5 yr or 10 yr interval – for the next 50 yrs, etc, etc. But longitudinal studies may include studies done at a specific moment in time – about phenomena that extend over a very long time. Analysis of supreme court decisions in a specific case matter over the past 20 or 30 yrs would be longitudinal, even if it is conducted in one year. There are three special types of longitudinal studies. …Longitudinal Studies three special types: Trend studies Cohort studies Panel studies Trend Studies Studies that observe changes within a specific phenomenon (group, nature, instances, etc) over time. Where the trend in which specific events unfold is observed. Example: observing the temperature changes between Winter and summer over a 30 yr period – to make sense of the global warming on climate change. …Longitudinal Studies …Cohort Studies The difference here is that you select a sub-group or sub-element, like the age group or time group. Example: conducting a study every ten years - about economic attitudes of World War II Veterans. …Panel Studies Similar to the above, except that you observe exactly the same persons every time. You may observe the same persons every five yrs – for the next 30 yrs. In observing changes in spending patterns, this study may be appropriate, WHY? SHORT RECAP - Research & Process: Getting Started Starting from a particular research interest Ask questions, read literature Identify the problem for study Clarify the questions to be answered. DO CONCEPTUALISATION Operationalise Select the METHOD of Enquiry Start your observations Process data Analyse that data It is important to set out a clear Time Frame & Budget Research & Research Process Conceptualisation Here you must be clear about Key VARIABLES to be studied, How are you going to define them, How are you going to measure them (operationalisation) Concepts & conceptions A concept is “a technical term for that mental image” so that its meaning can be shared by others with no physical access to your mind. Conceptualisation - process in which we clarify what we (and will) mean when we use a particular term. It involves the specification of Variables (& the Attributes composing them). A variable is a logical set of attributes of a phenomenon – for example: Employment Status is a variable composed of Employed & Unemployed Digital divide is a variable composed of … and …? Research & Research Process …Variables Every variable must have 2 qualities: Its attributes must be exhaustive. For example, if you are measuring political party affiliation, you cannot just give the DA & ANC as the attributes. What if other respondents need to mark the IFP, the DM, and others. So, you will need to exhaust all the attributes of a variable to enable adequate responses. Attributes of a variable must be mutually exclusive. If you discuss employment status for example, you need to define your attributes in such a way that no person can both be EMPLOYED & UNEMPLOYED at the same time. Being employed should exclude being unemployed. That leads us to the subject of INDICATORS & DIMENSIONS The Research Onion Phenomenology Inductive Philosophy/Epistemology Research Approach Research Strategies •Analyzing existing documents •Observations •Interviews •Questionnaires Qualitative and Quantitative Analytical Techniques Deductive Positivism The Time Dimension Data Collection Methods Data Analysis Techniques Research Methodology IV Referencing & Research Ethics Literature Review & Referencing Literature Review always goes with referencing. As a recap: In addition to the literature about your research topic, also consult the literature about your context. e.g. Mobile learning in a tertiary institution in South Africa you need to say something about tertiary institutions (based on references) + something a lot about Mobile learning generally, as well as about the South African context (that applies to your research). If you conduct research on the use of ICT to support AIDS treatment in Southern Africa – you may have to refer to AIDS literature as well as the latest WHO (World Health Organisation) report to obtain the statistics required to substantiate your research. - Obviously, You need to work with literature on ICT for this as well. Not just one set but both sets apply equally. Literature Review & Referencing …Literature review Some guidelines for deciding how to present a reference in the literature study: What are the argument/s & contribution/s of the author/s? Does this differ from other author/s conducting similar research? If so – how does it differ? Are there reasons for differences (e.g. a different context)? You can introduce an alternative view as follows: e.g. However, …./ In contrast…. Similarly – does this confirm what others have said/found? In those cases you can report something like: generally ….. apply to …… (ref1, ref2, ref3). Why are they saying that? Are such reasons applicable or not applicable to your research? When you refer to other authors’ works it is important that you say why you are referring to a specific argument/guidelines/ framework/… i.e. This is an important consideration for this research … because … Once you have completed, it is necessary to analyse your findings from the literature as a basis for your discussions throughout your document. Literature Review & Referencing Make sure that what you are writing tells a story (interesting), that it is cohesive and also attend to the flow of your writing. Your arguments and statements must be substantiated by (1) a reputable reference and (2) make logical sense. Avoid: Just providing a list of summarized references that are strung together in a disjointed way, i.e. there is no logical flow from the one section to the next. A list of bullet points – one can easily ask the question if the list is in fact complete – therefore only use a list of bullet points when you know for certain that the list is complete and representative, i.e. no one can add to or delete from the list Leaving the reader with the question “why am I reading this?” – “should I read the next part?” and finally – with a feeling of “so what”. Repeating what others have said (even in your own words) without some attempt to make sense of that, e.g. “what does this mean?”, “how does it apply to my research?”… The last point leads us to the subject of RESEARCH ETHICS & REREFENCING. Literature Review & Referencing …Ethics & Referencing Research Ethics: Important principle guiding relationships between science & the rest of the society is ACCOUNTABILITY. So, scientists cannot do whatever they want without regard for the rights of the society. Research ethics emphasizes that scientists conduct their research both in a SOCIALLY RESPONSIVE (& useful) as well as RESPONSIBLE manner: - Always adhere to the highest possible technical standards in your research (never take technical chances!!) - Always indicate at the end of your work, what the limits of your study were, and the methodological constraints that affect the extent of the validity of your study - Never misrepresent your results in any way!! - Never change (or fabricate) your data in any way (even if it leads to the findings that you dislike). Literature Review & Referencing …Research Ethics – What is ethics? Because of the significance of the Ethics or notion in research – most professional bodies and all credible research institutions (including universities) establish specific codes of ethical behaviour in research. Masters & Doctoral proposals should obtain ethics committee approval before research can be allowed. In research interviews for example, you will need to declare that you will not abuse, compel, deceive & redicule your participants, and that you will not subject them to inhume types of tests. In the case of interviews for example, you should not do THIS Researchers therefore abide by the following principles: - rejection of secrete research - obligation to free & open dissemination of research results - responsibility to sponsors of research - integrity in methods and handling of data, findings, & reporting - Appropriate ascription of authorship to a manuscript - No simultaneous submission of manuscripts to different publications - REJECTION OF ANY FORM OF PLAGIARISM. Literature Review & Referencing Referencing What is referencing, why is it important, and how to do it correctly? It is a standardised method of acknowledging sources of information (and ideas) used in your assignment to uniquely identify their source. Direct quotations, facts, figures, as well as ideas and theories, from both published and unpublished works, must be referenced. Information obtained from any source, including the Internet, is covered by copyright law. You must acknowledge any source that you refer to in your assignment, both within the text of your assignment, and at the end of it (by including a list of references). Referencing your sources also enables the reader to view your sources Literature Review & Referencing …Some Referencing Styles Did I say “Reject any form of PLAGIRISM?” Statement implies strict adherence to full & correct referencing. Using someone else’s work – and then claiming that it is your own is tantamount to stealing. Stealing someone’s work!! Such theft in research terms is known as plagiarism. Remember that you are also required to adhere to the highest technical standards possible. So, it is not enough to reference, but it has to be correct, and most of all, consistent. Please remember the CONSISTENCY part!! What consistency…? You see, there are numerous referencing styles. To make life easier, most institutions decide on the most preferable style for use by its students/ researchers/ authors. When you write a research paper for a conference or journal for example, they will tell you their preferred referencing style – for consistency among all papers they publish. Literature Review & Referencing Let us discuss some referencing styles below. … Oh, Holy Cow!!, why should we discuss referencing styles now? You ask. Because many students (and amateur writers) tend to mix different referencing styles in one piece of work (a lack of technical consistency). You should know these so that you can also AVOID INCONSISTENT REFERENCING (mixing Styles). We use the Harvard Style at CPUT!! … Some styles: Harvard Referencing Style www.library.uq.edu.au/training/citation/harvard_6.pdf www.usq.edu.au/library/help/ehelp/ref_guides/harvardonline.htm http://library.curtin.edu.au/referencing/harvard.pdf www.lib.monash.edu.au/tutorials/citing/harvard.html APA Style [American Psychological Association (APA) http://library.curtin.edu.au/referencing/apa.pdf Oxford Style: www.usq.edu.au/library/help/ehelp/ref_guides/oxford.htm Vancouver Referencing Style http://library.curtin.edu.au/referencing/vancouver.pdf Chicago Style (footnotes) www.wisc.edu/writing/Handbook/DocChiWorksCited.html Oxford Referencing Style The Oxford (documentary-note) referencing system/ style consists of: Citations in the body of the paper, using a superscript (raised) number, generally at the end of a sentence Footnotes at the bottom (foot) of each page, for all citations on that page, or endnotes if they appear at the end of a chapter, section or other thesis A reference list (wrongly known as bibliography) at the end of the paper giving the details of each source referred to and possibly other materials consulted. Oxford Style: Some examples In the reference list at the end of the paper: See how the (a) author names, and (b) the date, are written 1 S Kostof, A history of architecture: settings and rituals, 2nd edn, Oxford University Press, New York, 1995, p. 35. 2 M Levey, Rococo to revolution: major trends in eighteenth-century painting, Thames and Hudson, London, 1966, p.14. 3 M Levey, Painting in eighteenth-century Venice, 2nd edn, Phaidon, Oxford, 1980. Vancouver Style Vancouver is a "numbered" style, that follows rules of the International Committee of Medical Journal Editors. It is a requirement for Manuscripts submitted to Biomedical Journals. A number is assigned to each reference as it is cited. A number must be used even if an author was named in the sentence, eg. Smith [12] argued that... Use double quotation marks to enclose a direct quotation. Type [sic] after a misspelled word or an incorrect or apparently absurd statement in quoted material to indicate that this is an accurate rendition of the original source. Use single quotation marks for quotations within quotations. The original number assigned to a reference is re-used every time the reference is cited in text, regardless of the previous position in text Vancouver Style: Examples The coach can carry out his own assessment of the athlete [5,9] in relation to the agreed constructs and so pinpoint areas of agreement on the one hand, [2-4] and differing perceptions on the other. Butler and Hardy maintain "that people's intrinsic motivation could be weakened by the application of external controls".[1] Reference list (again, see names & dates): Baker PN, editor.

It is very important that you use the right punctuation and that the order of details in the reference is also correct. Latin Abbreviations Latin forms must be used correctly. ibid. (ibidem), meaning, in the same place), relates to the same work, cited immediately before. op. cit. (opera citato, meaning in the work cited ) refers to a different page of a work cited earlier. loc. cit. (loco citato, meaning in the place cited) refers to the same page of a work cited earlier.
