Summary of Finding and Managing Scientific Sources

  • Importance of Skills: Finding scientific sources and managing them are essential skills acquired during university studies, enabling the navigation of vast digital academic landscapes.

  • Support Provided: Students at Indiana University (IU) are supported by the Library and Information Services (LIS) team through workshops and individual consultations.

  • Evaluation of Sources:

    • Sources must be carefully evaluated to determine their appropriateness for citation in academic work.

    • Systematic management of sources, utilizing suitable software (e.g., Zotero, Mendeley, or Citavi), aids in creating references and bibliographies in correct formats (APA, MLA, etc.).

  • Effective Reading Techniques: Includes strategies like SQ3R (Survey, Question, Read, Recite, Review) to quickly extract important information.

  • Citation Guidelines: Citing scientific sources must adhere to IU’s General Citation Guidelines to avoid plagiarism, which is the act of presenting someone else's work as your own.

  • Literature Discussion: Discussing literature on a topic helps form the foundation for independent arguments by highlighting gaps in current research.

Research Designs: Study Goals

  • Completion Outcomes: Upon completion, students will be able to:

    • Discuss differences between fundamental research designs such as cross-sectional, longitudinal, and experimental studies.

    • Identify key properties of basic scientific formats like monographs vs. journal articles.

    • Discuss advantages (generalizability) and disadvantages (lack of depth) of quantitative research, and vice versa for qualitative designs.

    • Name specific methods for data collection (e.g., Likert scales, semi-structured interviews).

Research Designs: Introduction

  • Role of Research Design: It serves as a blueprint or logical structure of the inquiry, ensuring the evidence obtained enables the researcher to answer the initial questions as unambiguously as possible.

  • Key Considerations:

    • Identify relevant academic formats in IT, such as technical reports or conference papers.

    • Determine approach: Qualitative (exploratory) vs. Quantitative (confirmatory).

  • Quantitative Research: Focuses on numerical measurements to either:

    • Deductively test established theories (Theory -> Hypothesis -> Observation -> Confirmation).

    • Inductively test falsifiability (e.g., recording sensor data from 100100 nodes to find patterns).

  • Qualitative Research: Aims for a deep, holistic understanding of social phenomena. In IT, this includes UX research and Human-Computer Interaction (HCI).

  • Research Method Selection factors:

    • Research Goal: Whether to Explain (causal), Understand (meaning), Predict (forecasting), or Criticize (emancipatory).

    • Pragmatic constraints: Time limits (33-66 months for a thesis) and budget constraints for data acquisition.

Key Formats of Written Work

4.1 Types of Research Formats
  1. Empirical Research:

    • Collects original primary data to answer a specific research question.

    • Systematic cycle: Problem definition -> Research design -> Data collection -> Data analysis -> Interpretation.

  2. Literature and Review Work:

    • A secondary research format providing a meta-level summary.

    • Systematic Reviews: Follow a strict protocol to find all relevant studies on a topic.

  3. Design Science Research (DSR):

    • Predominant in Information Systems; focuses on solving problems via artifacts (e.g., algorithms, interfaces).

    • The 7 Principles of DSR:

    1. Artifact Design: Must be a construct, model, method, or instantiation.

    2. Problem Relevance: Must solve an identified business or technical problem.

    3. Design Evaluation: Requires rigorous utility, quality, and efficacy tests.

    4. Research Contributions: Must provide clear contributions to the knowledge base.

    5. Research Rigor: Requires rigorous methods in both construction and evaluation.

    6. Design Optimization: Iterative search process to reach a solution.

    7. Communication: Results must be presented to technology-oriented and management-oriented audiences.

Correlations

  • Definition: A statistical measure (expressed by a coefficient between 1-1 and 11) that describes the size and direction of a relationship between two variables.

  • Caution: Correlation (XX and YY move together) does not imply causation (XX causes YY).

4.2 Methods: Quantitative or Qualitative?
Qualitative Methods
  • Smaller, non-representative samples (n < 20) prioritized for depth.

  • Techniques include Grounded Theory or Ethnomethodology.

Quantitative Methods
  • Large samples (n > 100) prioritized for statistical power.

  • Big Data: Involves the 33 Vs: Volume, Velocity, and Variety, requiring specialized processing beyond standard databases.

Method Triangulation
  • Purpose: To overcome the intrinsic biases and problems of a single method.

  • Types:

    • Data Triangulation: Using different data sources (e.g., at different times or from different people).

    • Investigator Triangulation: Using multiple observers or interviewers to reduce subjective bias.

    • Theory Triangulation: Using multiple theoretical schemes to interpret the results.

    • Methodological Triangulation: Using multiple methods, such as a survey followed by an interview.

Data Collection Methods

Qualitative Methods
  • Data Saturation: The point in data collection when no new information or themes are observed in the data.

  • Quality Criteria:

    • Credibility: Internal consistency.

    • Transferability: Contextual applicability.

    • Dependability: Traceability of the process.

Quantitative Methods
  • Experiments: Manipulate an independent variable (XX) to see the effect on a dependent variable (YY) while controlling for extraneous variables.

  • Quality Criteria:

    • Objectivity: Result is independent of the researcher (robj1r_{obj} \rightarrow 1).

    • Reliability: Consistency of the measurement instrument (rrel1r_{rel} \rightarrow 1).

    • Validity: The instrument measures what it is intended to measure (rval1r_{val} \rightarrow 1).

Data Evaluation Methods

Qualitative Methods
  • Coding: Labeling and organizing data to identify themes. Software like MAXQDA or NVivo automates the organization of codes.

Quantitative Methods
  • Data Cleansing: Identifying and correcting (or removing) corrupt or inaccurate records (e.g., outliers or missing values).

  • Analysis levels:

    • Univariate: Analysis of 11 variable (e.g., mean, median).

    • Bivariate: Analysis of the relationship between 22 variables (e.g., Scatter plots).

    • Multivariate: Analysis of 33 or more variables simultaneously (e.g., Multiple Regression).
