• Personality insights from sensor data
• Tone analyzer from text
• Chatbot impact on person / virtual coaches
Eye tracking forms
- wearable (camera included to record what the person is looking at): always dark pupil effect
- computer screen: switches from bright to dark pupil effect
- webcam
= different gaze points, illuminators, algorithms
Need more literature
• Extend search terms (more/better synonyms), using OR
• Less precise or demanding; drop aspects, less AND
• Search in more databases, search engines, websites
• Search in more languages (German, French, Dutch...)
• Use broader search fields; abstract or full text instead of title
• Use truncation to broaden the search; child* instead of children
• Use database thesaurus or subject headings
• Use reference list or cited-by to find older/newer articles (snowballing)
• Contact institutions or authors who are working on the subject
• Set up alerts to stay informed of new relevant publications
Search profile; search strategies
Hyphens
Wildcards
Proximity operators
Hyphens: well-being
Wildcards: term wom?n will retrieve results such as woman, women, and womyn (?, #, $)
--> allows you to perform a single character wildcard search
Proximity operators: WITH, PRE, W/
--> narrow searches by finding words that are next to, near, or within a specified distance from each other
Boolean Operators
AND, OR, NOT
AND: narrows a search
OR: broadens a search
NOT: narrows a search by excluding
Mixed methods
• Combination of different methods
• Often quantitative and qualitative
• For example: interviews after a survey
• Triangulation
– Multiple methods to answer the same research question
– Increases the validity of the research
Parsimony (‘economy’) principle
– Choose the minimal design needed to answer the research
questions properly (not more, not less)
Research questions for exploratory - quantitative research
– Descriptive
• How often do students use Facebook?
• For what reasons do students use Facebook?
– Comparison
• What differences exist in the use of Facebook between female
and male students?
– Relations
• Is the degree to which students use Facebook related to
personality?
Identity
▪Multiple
▪Dynamic
▪Situated
▪Relational
▪ Acknowledging incoherence and dynamics of identity formation
▪ From normative to descriptive
▪ From internal state to linguistic expression and embodied
enactment (identity in what you do and say)
Need less literature (irrelevant results)
• Make sure terms aren’t truncated too shortly, e.g. car*
• Use NEAR or other proximity operators
• Use phrase searching where it makes sense, e.g. “social media”
• Exclude unwanted meanings (with homonyms), using (AND) NOT
• Refine/filter results on subject area
• Search using subject headings or classification terms (e.g. patent
search)
Impact factor
h-index
Altmetrics
Impact factor: measure of the frequency with which the average article in a journal has been cited in a particular year
h-index: Kennzahl für die weltweite Wahrnehmung eines Wissenschaftlers in Fachkreisen
Altmetrics: tell you how often journal articles and other scholarly outputs like datasets are discussed and used around the world
