We present a study that examines how a social media activism campaign aimed
at improving gender diversity within engineering gained and maintained momentum
in its early period. We examined over 50,000 Tweets posted over the first ~75
days of the #ILookLikeAnEngineer campaign and found that diverse participation
- of types of users - increased activity at crucial moments. We categorize
these triggers into four types: 1) Event-Driven: Alignment of the campaign with
offline events related to the issue (Diversity SFO, Disrupt, etc.); 2)
Media-Driven: News coverage of the events in the media (TechCrunch, CNN, BBC,
etc.); 3) Industry-Driven: Web participation in the campaign by large
organizations (Microsoft, Tesla, GE, Cisco, etc.); and 4) Personality-Driven:
Alignment of the events with popular and/or known personalities (e.g. Isis
Anchalee; Michelle Sun; Ada Lovelace.) This study illustrates how one mechanism
- triggering - supports connective action in social media campaign.

研究社交媒体行动主义活动如何利用触发机制来促进获得和维持动力，以实现工程领域的性别多样化，发现多样化的参与类型会在至关重要的时刻增加活动性。触发机制分为四种类型：与离线事件对齐，媒体报道，行业参与和知名人物对齐。
