Understanding parental leave experiences: connecting the dots with a multiple-methods approach

ABSTRACT

This research note draws selected findings from a multiple-methods study conducted in partnership with a large public-sector employer in Portland, OR to describe the added value of this approach for research translation. We focus on how our study of a newly implemented paid parental leave policy can translate to actionable steps for two important end-users: employers and policymakers. Using administrative records (N?=?579), a countywide employee survey (N?=?137 leave-takers) and focus groups (N?=?35), we describe how each data source contributes important and unique information about how the policy’s implementation affected diverse employees. We find gender differences in how employees changed leave-taking in response to the policy, and describe the critical but nuanced role that supervisors play. Working with employers and policymakers to develop and implement thoughtful policies will help to ensure equitable distribution of the benefits of paid leave policies.     

I’m not like everybody else: urbanization factors shaping spatial distribution of native and invasive ants are species-specific

Urbanization is a major global change inducing complex and multiple modifications of landscapes and ecosystems. The spatial distributions of organisms experiencing these modifications will likely shift specifically, depending on each species’ response to each environmental modification induced by urbanization. We sampled two ant genera (Lasius and Tetramorium) at 1248 locations along an urbanization gradient in Lyon, France and used high resolution spatial layers for 18 spatial (e.g., open habitat fragmentation, bioclimatic data and surface temperatures) and temporal (e.g., comparison of Normalized Difference Vegetation Index between 1986 and 2015) environmental variables associated with urbanization. Coupling two different analytical methods (Outlying Mean Index and Boosted Regression Trees), we showed that each species’ distribution was influenced by its own combination of environmental factors. Two morphologically cryptic Tetramorium species (T. sp.E and T. sp.U2) were both highly abundant but with opposite responses to urbanization: while T. sp.E was favored by urbanized habitat, T. sp.U2 avoided urbanized areas. Among Lasius species, we detected 63 occurrences of the invasive ant Lasius neglectus, the distribution of which was favored only by embankments along roads. We found that, even at this reduced spatial scale, climatic effects influenced most species and interacted with urbanization factors.
