In recent years, online privacy literacy has often been regarded as a potential solution to people’s seemingly paradoxical behaviors in online environments. Based on empirical findings that Internet users rarely implement privacy and data protection strategies, it has been suggested that they are simply not literate enough to make informed decisions in online environments. Throughout the last years, we have been working on reconceptualizing online privacy literacy and providing reliable and validated instruments to measure online… Read More »Reconceptualizing online privacy literacy
When a year comes to an end, many blogger seem to have this urge to do one of these “Best of 2018” posts. The blogosphere is full of lists, thoughts, personal accomplishments and idiosyncratic meditations and resolutions. It is almost too much. Yet, I have to admit that I quite like to scroll through at least some of them, thereby realizing someone’s personal taste and likes as well as finding common themes and topics in… Read More »What I read, heard and watched in 2018
I recently gave a workshop on data visualization. One of the topics was visualizing interaction effects (or “moderation” analyses). I think it is a great topic because it exemplifies quite well that there is not one solution to all problems. In general, I would argue that trying to visualize interaction effects is great idea. Due to the conditional nature of the effects obtained from standard regression analyses that include an interaction term, it is often… Read More »How to visualize interaction effects
I finally can say that I published my dissertation. Although my defense was already in December, it took some time to wrap everything up and get the book published. But what did I actually write about? Using both a theoretical argumentation and an empirical investigation, I rationalize the view that in order to understand people’s privacy perceptions and behaviors, we need to adopt a situational perspective. To this end, the book is divided into three… Read More »Book published: Situational Privacy and Self-Disclosure
Have you ever thought about centering your variables before running an regression based analysis? From my personal experiences, chances are high are that you haven’t: Although a useful data transformation procedure for many statistical analyses, centering is seldom taught in fundamental statistic courses. Although the mathematical principles behind it may seem arbitrary, its implications are oftentimes quite strong. Although centering is already useful in standard statistical modeling (e.g., OLS regression), its usefulness is particularly evident… Read More »How to center in multilevel models
If you have ever been on this website before, you might realize that the design changed slightly and some new contents appear on a couple of sites. Yes, I did move to wordpress. Although it was great fun to create this website from scratch and keep it simple and fast by implementing only basic html and css, I nonetheless missed some more elaborate functions that I could not program myself (e.g., comments, tags, categories, footnotes…).… Read More »Hello and welcome back!
