Hier sind unsere erste Ergebnisse aus unserer Studie rund um Autismus im Software Engineering. Erkennt ihr euch darin wieder? Fehlen Themen, sind eure Erfahrungen ganz anders? Meldet euch gern :) @svenapel.bsky.social, @janetsiegmund.bsky.social Isabella Graßl, Stefan Sobernig #autism #se
Quadratische Sharepic-Grafik mit der Überschrift „Stärken erkennen“. Links steht eine gezeichnete, lächelnde Person mit erhobener Faust. Rechts befinden sich sechs grüne Themenfelder mit Icons: „Neugier und Offenheit für Neues“, „Andere unterstützen“, „Bewusste Kommunikation“, „Hohe Persönliche Standards“, „Leitung zielführender Meetings“ und „Interesse an Herausforderung“. Die Grafik wirkt positiv und ermutigend.Quadratische Sharepic-Grafik mit der Überschrift „Handlungsbedarf“. Links steht eine gezeichnete Person mit verschränkten Armen und verärgertem Gesichtsausdruck; neben dem Kopf sind Dampfwolken als Zeichen von Frustration zu sehen. Rechts stehen sechs farbige Themenfelder mit Icons: „Bedürfnis nach Struktur“, „Sinnhaftigkeit der Arbeit“, „Probleme in sozialen Situationen“, „Zu viele Stimuli“, „Einhaltung persönlicher Standards für Arbeit“ und „Verantwortungen fair verteilen“. Die Grafik macht deutlich, wo aus Sicht der Forschung Handlungsbedarf besteht.Quadratische Sharepic-Grafik mit der Überschrift „Autismus am Arbeitsplatz“. Links sitzt eine gezeichnete Person mit schwarzem Dutt an einem Tisch vor einem Laptop. Rechts stehen drei gelbe Themenfelder mit Icons: „Was spricht für ein Outing“, „Was spricht gegen ein Outing“ und „Wem gegenüber ist man geoutet“. Die Grafik nutzt warme Beige-, Gelb- und Brauntöne.Quadratische Sharepic-Grafik mit der Überschrift „Eure Forschungsthemen“. Links steht eine gezeichnete Person mit roten Haaren, Brille und einem Buch in der Hand. Rechts sind drei rosa Themenfelder mit Icons zu sehen: „Abbau von Vorurteilen“, „Entstehung sozialer Normen“ und „Empowerment“. Die Grafik ist freundlich gestaltet und nutzt helle Rosa-, Beige- und Violetttöne.

Occasionally, I get a reviewer complaining, “You don’t compare against any other approach. So how can we know you’re better?” So I found a simple way to still add the "bold number column" that apparently everybody wants these days.
Table with three columns: one "other approaches", all with 0%; one "our approach", with bold, non-zero percentages; and one "improvement", showing infinite improvement in all cases.

Correct. If the birthdate field contains corrupt or mismatched data, it defaults to 1875-05-20, which serves as a flag. May 20, 1875, is the day the international standards and metrics treaty was signed. Everything is a conspiracy when you don’t know how anything works.
