人类环境科学中的一类问题侧重于个人或家庭行为与当地地理环境之间的关系。这些问题的核心是人们的地理流动性的本质，以及他们在不同时空尺度上的位置稳定性的持续时间。研究人员面临的问题是，流动性/稳定性的过程在时间和空间上是动态的，因此难以测量。由于时间和空间是连续的，分析人员必须选择适合所讨论问题的地点的时间长度和空间尺度的聚合级别。以前的工作强调流动性和抑制稳定性作为一个分析范畴。我在这里关注的是稳定性，并说明分析个体的稳定性需要分析他们的流动性。通过一个以企业家精神和地方之间关系为中心的实证例子，我展示了对稳定性的关注如何通过强调稳定性/流动性的时间和空间维度之间的相互依存来解决测量问题。
A class of questions in the human environment sciences focuses on the relationship between individual or household behavior and local geographic context. Central to these questions is the nature of people's geographic mobility as well as the duration of their locational stability at varying spatial and temporal scales. The problem for researchers is that the processes of mobility/stability are temporally and spatially dynamic and therefore difficult to measure. Whereas time and space are continuous, analysts must select levels of aggregation for both length of time in place and spatial scale of place that fit with the problem in question. Previous work has emphasized mobility and suppressed stability as an analytic category. I focus here on stability and show how analyzing individuals' stability requires also analyzing their mobility. Through an empirical example centered on the relationship between entrepreneurship and place, I demonstrate how a spotlight on stability illuminates a resolution to the measurement problem by highlighting the interdependence between the time and space dimensions of stability/mobility.
