翻译：经理们（管理者们）必须具备有限的理性，并能够完全预见到当他们浏览组织管理结构时，他们的经历、期望和机率性的判断将会对公司投资组合资源的管理造成影响。
注意：take as a given their bounded rationality应理解为take their bounded rationality as a given 字面意思把他们的有限理性看作是给定的

.........take as a given their bounded rationality, and can fully expect that their history, their expectations, and the probabilistic judgments that they make when scanning the organizational context will have an impact on the way they manage the firm’s portfolio of resources.

挺有意思的句子，试着翻一下，论坛币就不用给我了。

由于存在理性上的限制，当对组织环境的浏览影响了他们管理公司资源的组合的方式时，他们的生平，他们的期望，他们作出或然性判断（这些因素）都是能被经理们完全预料到的。
