Key Concepts: Data Analysis Techniques

Powell
  • The basic purpose of statistical analysis is to summarize observations/data in such a manner that they provide answers to a hypothesis or research question.
  • Descriptive statistics deal with the tabulation of data: their presentation is in tabular, graphical, or pictorial form.  This kind of statistical analysis can characterize what is typical in a group, indicate how widely cases in the group vary, show relationships between variables and groups, and summarize data.
  • Inferential statistics are used for making inductive generalizations about populations based on sample data and for testing hypotheses.  This kind of statistical analysis can estimate population parameters and test the significance of relationships between and among variables.
Wildemuth
  • Content analysis is the systematic, objective, quantitative analysis of message characteristics.  This form of data analysis is only interested in content characteristics related to the hypothesis or research question.  A set of codes is to capture those characteristics is developed and finalized before analysis begins.  Content analysis is deductive and can deal with large, randomly selected samples.
  • Chi-square statistic measures the difference between what was observed and what would be expected in the general population.  The chi-square statistic can be used to test the null hypothesis that there is no relationship between the two variables.

Key Concepts: Data Collection Techniques

Powell
  • Focus group - a group interview designed to explore in depth the feelings and beliefs people hold and to learn how these beliefs shape overt behavior.  Generally, the discussions start broadly and gradually narrow down to the focus of the research.
  • Usability testing - form of human ethnographic observation combined with ergonomics and cognitive psychology.
 Wildemuth
  • Think-aloud protocols - research method used to understand the subjects' cognitive processes based on their verbal reports of their thoughts during experiments. Its purpose is to obtain information about what happens in the human mind when it processes information to solve problems or make decisions in diverse contexts.
  • Participant observation - research method in which (1) the researcher is a participant in the setting; (2) such participation leads to a better understanding of the people and social processes that occur within that setting; and (3) this understanding can lead to better theories about social processes in that setting and similar settings.  The challenge to the researcher is balancing the roles of participant and observer.
  • Research diaries - research method that that comprises a varied set of data collection instruments and techniques that range from descriptive event logs to narrative personal accounts. Research can conceptually resemble other data collection methods such as the questionnaire, the interview, or observation.

Article Review #2

Ashley Smith

Article #2

Bell, S., & Sarr, N. (2010). Case study: Re-engineering an institutional repository to engage users. New Review of Academic Librarianship, 16(S1), 77-89. doi:10.1080/13614533.2010.509517

Introduction
Institutional repositories (IRs) provide a digital medium in which faculty and graduate students can preserve and disseminate their scholarly work with relative ease.  In 2003, the Libraries at the University of Rochester launched UR Research, an IR initiative that was mostly ignored by the academic community.  To figure out how to obtain academic buy-in of the IR, the Libraries conducted two work-practice studies that focused on the work habits of faculty and graduate students to determine how to redesign an IR that could easily be incorporated into their work flow.  I chose to critique this article because I’m interested in learning about the kinds of features that make an IR attractive to its users.

Problem Statement
The authors focus their research study on how to design an IR that will that complement the work needs of faculty and graduate students.

Literature Review
There is no literature review in the article; however, there is a note section at the end of the article which refers the reader to a literature review written by different authors in a different journal article. 

Method
The researchers designed and conducted two separate work-practice studies on two segments of the academic community, faculty and graduate students, to discover how they use digital technology to do research and disseminate their scholarly materials.  These segments came from diverse academic disciplines: humanities and social and physical sciences.  The researchers videotaped one-hour observations and followed up with phone and group interviews. 

After they finished gathering data from their field work, the researchers transcribed the videotaped observations and interviews and analyzed their findings.  Work-practice studies have their roots in anthropology, and the researchers analyzed the data through a combination of anthropological means and a creative process. 

Caveat
I had a few problems with this article.  First, the authors didn’t discuss or summarize the salient points of their methodology in this article.  Instead, they referred the reader to two previous articles that described the University of Rochester work-practice studies.  I had to read those other articles to gain more in-depth information on the research methodology.  Another problem was how the authors gave little detail of how they analyzed the data.  Despite several readings, I’m still unclear on what exactly it means to analyze data by anthropological means combined with a creative process.  The researchers don’t provide further information about this particular kind analysis, and that raises concerns about the research study’s validity and reliability.  My last problem was the lack of a literature review in the article.  It would be helpful to have some context of how the researchers decided to apply work-practice studies in their research on adapting IRs to better suit faculty and graduate students’ work needs.

Key Concepts: Methods, Ethics, & Theory

Powell
  • Evaluative research - a type of applied research that has as its goal the testing of the application of knowledge within a specific program or project. In most evaluative research, there is an implicit (or explicit) hypothesis in which the dependent variable is a desired value, goal, or effect and the independent variable is usually a program or service.  The two general types of evaluative research are summative (outcome) evaluation and formative (process) evaluation  .
  • Institutional Review Boards (IRBs) - the U.S. government requires that all universities and other organizations that conduct research involving human subjects and that receive federal funding for research involving human subjects have an IRB.  The purpose of the IRB is: (1) to help ensure that that no harm will come to human subjects; (2) that the human subjects are informed of and consent to the protocol of the research study; and (3) that the human subjects' confidentiality or anonymity will be protected.
  • Survey - the survey is a group of research methods commonly used to determine the present status of a given phenomenon.  The basic assumption of most survey research is that one can make inferences about a large group of elements by studying a relatively small number (sample) selected from the larger group (population) by carefully following scientific procedures.
  • Sampling error/standard error of the mean - sampling error represents how much the average of the means of an infinite number of samples drawn from a population deviates from the actual mean of that same population.
Wildemuth
  • Middle-range theories - theories that are concrete enough to apply to phenomena of interest to a special field, like library and information science, but are also abstract enough to apply to settings beyond the context of which they were originally developed.
  • Grounded theory - theory emerges simultaneously with the collection of data.  It isn't a separate process.  Rather than testing an existing theory, the grounded theory approach begins to formulate a theory that fits the data as the data emerge.
  • Typology - a comprehensive list of theoretical concepts/categories and their definitions.

Key Concepts: Literature Reviews

Overview from Deakin University
  • Elements of the literature review: a list; a search; a survey; a vehicle for learning; a research facilitator; and a report.
  • The literature review does not report new primary scholarship itself.
Overview from the University of Toronto
  • A literature review is a piece of discursive prose, not a list describing or summarizing one piece of literature after another. Organize the literature review into sections that present themes or identify trends, including relevant theory. Try to synthesize and evaluate the literature according to the guiding concept of your thesis or research question.
  • Writing a literature review lets you gain and demonstrate skills in two areas: (1) information seeking, which is the ability to scan the literature efficiently, using manual or computerized methods, to identify a set of useful articles and books; and (2) critical appraisal, which is the ability to apply principles of analysis to identify unbiased and valid studies.
Overview from UNC
  •  Literature reviews have thesis statements. A thesis statement will not necessarily argue for a position or an opinion; rather it will argue for a particular perspective on the material.
  • Literature reviews should contain at least three basic elements: an introduction or background information section; the body of the review containing the discussion of sources; and, finally, a conclusion and/or recommendations section to end the paper.
    • Introduction: Gives a quick idea of the topic of the literature review, such as the central theme or organizational pattern.
    • Body: Contains your discussion of sources and is organized either chronologically, thematically, or methodologically (see below for more information on each).
    • Conclusions/Recommendations: Discuss what you have drawn from reviewing literature so far. Where might the discussion proceed?

Key Concepts: Developing the Study

Patten
  • Strict replications - A study that mimics a previous study; the purpose is to obtain the same results.
  • Modified replication - A study that is replicated from a previous study but with some major modifications.
  • Descriptor - A key subject-matter term
  • Record - All the information about a given article
  • Literature review tip 1 - When citing literature on each topic, group references together when they have something in common.
  • Literature review tip 2 - It is important to indicate the results of the research in the literature review, not just the description of the methodology.
Pyrczak
  • Tip 1 for evaluating literature reviews - Has the author avoided citing sources for a single point?
  • Tip 2 for evaluating literature reviews - Has the author distinguished between opinions and research findings?

Wildemuth
  • Symmetry of potential outcome - Concept of whether or not the initial hypothesis is confirmed does not matter because the findings of the study will still be useful.
  • Components of a good research question: (1) clear and easily understood; (2) specific enough to suggest the data that need to be collected; (3) answerable; and (4) interconnected with important concepts
  • Evidence-based information - Information professionals should base their decisions on the strongest evidence available.
  • Practice-based question - A research question that is abstract enough to be of interest beyond the local setting.
  • Hypothesis - A conjectural statement of the relation between two or more variables
  • Null hypothesis - A hypothesis that states there is no relationship between variables or no difference between one thing and another. 
Williams
  • Directional hypothesis - A hypothesis that indicates the relationship between, or among, variables.
  • The role of literature review - The literature review should include evaluative and critical judgments about the research literature, and that it should present a comparison of ideas and research findings, tying them together.

    Article Review #1

    Article Review #1

    Jihyun, K. (2011). Motivations of faculty self-archiving in institutional repositories.
    Journal of Academic Librarianship, 37(3), 246-254. Retrieved from EBSCOhost.

    Introduction
    Despite the growth of the Open Access (OA) movement and the greater ease of disseminating scholarly research through institutional repositories (IRs), many faculty members do not self-archive their research and journal articles in their institutions’ repositories.  This article explores two things:  (1) the factors that motivate faculty to deposit their scholarly research in their institution’s repositories and (2) the factors that impede them from self-archiving.  For my research topic, I’m interested in exploring ways to increase faculty contribution of their scholarly materials into their IRs.

    Problem Statement
    In her article, the author examines faculty members’ attitudes toward their institutions’ repositories and how four factors--costs, benefits, contextual factors, and individual traits--affect whether or not faculty are apt to self-archive their materials in IRs. 

    Literature Review
    Even though the author has almost fifty citations throughout her article, her literature review is only a one-sentence statement about how the body of literature is replete with studies that not only investigate faculty members’ attitudes toward IRs but also explore ways to increase their self-archiving rate.  Any kind of critical review consists primarily of previous studies that only measured faculty attitudes at one or two universities.  The author wanted to cast a wider net for her research.

    Method
    The author used an online survey and telephone interviews to gather data on faculty attitudes toward IRs at seventeen U.S., Carnegie doctorate-granting universities that have IRs.  Her sample was composed of two groups:  (1) 621 faculty members who had self-archived their research papers in their IRs and (2) 829 faculty members randomly selected from Science, Engineering, Social Science, and Humanities disciplines.  This second sample group included both faculty members whose disciplines had a firmly establish culture of self-archiving, such as Physics, Computer Science, and Economics, and other disciplines, such as Humanities, that did not have a strong culture of depositing materials in IRs.

    The survey questionnaire consisted of four parts: (1) faculty members’ self-archiving experience and awareness of IRs, (2) faculty members’ perception of self-archiving, (3) faculty members’ future plans for self-archiving, and (4) faculty members’ demographics.   Each question provided five answer choices: (1) Strongly agree, (2) Agree, (3) Neutral, (4) Disagree, and (5) Strongly Disagree.  From the survey results, the author used 684 responses, or 45.6% , for her research analysis.  She then applied a logistic regression analysis where the dependent variable was whether or not a faculty member had self-archived material in his/her IR and the independent variables were the costs, benefit, contextual factors, and individual traits factors. 

    After the conclusion of the online survey, the author e-mailed 151 faculty members who had indicated on the survey that she could contact them for a telephone interview.  Forty-one professors consented to be interviewed.  All telephone interviews were transcribed and then coded based on the four factors of costs, benefits, contextual factors, and individual traits. 
     
    Caveats
    My main caveat with the author’s research methodology focuses on reliability.  Would she obtain similar results if she surveyed and interviewed faculty members at smaller institutions, such as baccalaureate or professional schools?  Would she get comparable results if she studied faculty attitudes at academic institutions outside of the U.S.?  And, as mentioned earlier, the author's literature review was almost nonexistent.  Taking the time to discuss even just a couple of articles would help novice researchers understand why she approached the problem the way she did.
