#OpenScience principles help students gain lots of useful skills that are an advantage on the job market in and beyond academia. Read our latest book chapter where we provide tips for educators to bolster employability through open science: doi.org/10.31219/osf...

Open science contributes to more rigorous and impactful science. However, little attention is often paid to the benefits that it provides to its users, such as project management and programming skills. Although not its primary objective, these skills may be considered additional benefits supporting the transition to open science practices. Drawing from international perspectives, this chapter will discuss skills that students develop explicitly or implicitly by engaging in open science and their benefits to careers within and outside of academia. It will also showcase examples of how engagement in open science is considered in (academic) hiring decisions, including ongoing debates and areas for (structural) improvement. Ultimately, this chapter will inform educators about the most important open science skills and provide insights into how to strategically build a resume to present open science-related skills convincingly to improve employability, including practical tips and resources.

I feel you. And getting up is just the follow-up. It never ceases to amaze me how fast the little ones progress. If I'd learn in a year what they learn in a day I'd be happy :D

Thanks to everybody who chimed in!

I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist.

So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

🔍 What is Wearable Landscape?
An open-science project aiming to foster collaboration in the field of #Wearables. We want to bring experts together, to ultimately advance the validation and application in wearables that track 24-hour physical behavior (sleep, sedentary time, activity) #OpenScience

Exactly this :D, but you need documentation somewhere so you don't get lost. A nice feature would be an email path diagram to get through this mess.

I have a feeling we are revolutionalizing emails here...

Janis Fiedler @fiejanis.bsky.social · Apr 22

I feel you! Maybe we should start sending emails that self-delete once they are irrelevant...

In der Promotion fand ich Schreiben oft quälend, hab mit jeder Formulierung gekämpft & gehadert. Das hat sich inzwischen zum Glück verändert — v.a. durch Schreibkollaborationen, die das Zutrauen in mein Schreiben gestärkt haben, & durch Routine. Was ich daraus gelernt hab: Heute in #ArbeitInDerWiss!

Weiter im Text: Vom Schreiben inner- und außerhalb der Wissenschaft

Der beste Text ist einer, der gut genug ist, um fertig zu sein.
