<div class="sreweekly-title"><a href="http://lup.lub.lu.se/student-papers/record/2971193" target="_blank">Language Bias in Accident Investigation</a></div>
<div class="sreweekly-description">
<p>This Master&#8217;s thesis by Crista Vesel seeks to answer the question, &#8220;How does the language used in the U.S. Forest Service&#8217;s <i>Serious Accident Investigation Guide</i> bias accident investigation analysis?&#8221; It&#8217;s an awe-inspiring analysis, drawing on Dekker, Woods, Cook, and other authors I&#8217;ve linked here repeatedly.</p>
<p>The most exciting part for me was the confirmation of some vague thoughts I&#8217;ve had around the use of passive versus active voice in retrospectives. By using passive voice, we can seek to reduce the kind of blaming that is inherent in active/agentive language.</p>

<div class="sreweekly-description">
<p>PagerDuty&#8217;s take on automating chaos includes a chat-bot that lets folks trigger one-off host failures, along with running periodically, of course.</p>
<blockquote><p>Unfortunately, ChaosCat is significantly tied into our internal infrastructure tooling. For the moment this means we won’t be open-sourcing it.</p></blockquote>
