Science is one of the top interdisciplinary peer-reviewed journals with a very wide audience, and since 1996 it has dedicated a section of its website, Science Careers, to career news and advice. As Science Careers has been active, the academic job market has been transforming, most notably by a decrease in the availability of tenure-track academic positions. Using a dataset of 6111 full-text Science Careers articles we perform an exploratory text analysis to characterize the changes in framing, topics, and scope of career content. We analyzed tag frequency and word frequency to examine topics over time. We tracked the relative prominence of articles that explicitly present advice to the reader, as opposed to more descriptive articles about workforce dynamics or personal experiences of career scientists. We find that although the number of articles tagged Advice had remained consistently high from the inception of the Science Careers section, 2015 marked the beginning of a significant decrease in the number of explicitly tagged Advice articles. The apparent disinclination for strongly prescriptive advice may indicate a growing sense, even within an academic-oriented venue, that career-pathways for researchers have become less predictable, making dispensing broadly applicable advice more challenging.

科学是跨学科的顶级跨学科期刊之一，拥有广泛的受众，自1996年以来，它在其网站“科学职业”中专门介绍了职业新闻和建议。随着科学职业的活跃发展，学术工作市场正在发生变化，最显着的趋势是终身任职的学术职位的减少。使用6111全文科学数据集在职业文章中，我们进行了探索性的文本分析，以描述框架，主题和职业内容范围的变化。我们分析了标签频率和单词频率，以检查主题随时间的变化。我们跟踪了向读者明确提出建议的文章的相对突出程度，而不是有关劳动力动态或职业科学家个人经历的更具描述性的文章。我们发现，尽管自《科学》创立以来，标记为“建议”的文章的数量一直保持较高水平2015年的“职业”部分标志着显着标记的“建议”文章数量开始显着减少。即使是在以学术为导向的场所内，强烈建议性建议的明显偏离也可能表明一种增长的感觉，即研究人员的职业道路变得难以预测，这使得分配广泛适用的建议更具挑战性。
