Sequential Specification Tests to Choose a Model: A Change-Point Approach

Researchers faced with a sequence of candidate model specifications must often choose the best specification that does not violate a testable identification assumption. One option in this scenario is sequential specification tests: hypothesis tests of the identification assumption over the sequence. Borrowing an idea from the change-point literature, this paper shows how to use the distribution of p-values from sequential specification tests to estimate the point in the sequence where the identification assumption ceases to hold. Unlike current approaches, this method is robust to individual errant p-values and does not require choosing a test level or tuning parameter. This paper demonstrates the method's properties with a simulation study, and illustrates it by application to the problems of choosing a bandwidth in a regression discontinuity design while maintaining covariate balance and of choosing a lag order for a time series model

Accessing Socially Excluded People — Trust and the Gatekeeper in the Researcher-Participant Relationship

This paper describes methodological findings from research to recruit and research hard-to-reach socially excluded people. We review the ways in which researchers have used particular strategies to access hard-to-reach individuals and groups and note that little attention has been given to understanding the implications of the nature of the trust relationship between researcher and participant. Gatekeepers invariably play a role in accessing socially excluded people in research, yet discussion to date invariably focuses on the instrumental role gatekeepers play in facilitating researchers\' access. In this paper we explore the possibilities for analysing relationships in terms of trust and distrust between gatekeeper and socially excluded participant. Our analysis considers the different kinds of relationships that exist between gatekeepers and socially excluded people and, in particular, the relationships of power between gatekeepers and socially excluded people. Insights into the nature of trust among socially excluded people will also be considered. Finally, we discuss how size and use of social networks among socially excluded groups and perceptions of risk in interactions with gatekeepers are important to understanding the possibilities for trustful relationships, and for meaningful and successful access for researchers to socially excluded individuals and groups.Social Exclusion, Access, Research, Gatekeepers, Trust, Distrust, Risk

Postsecondary Achievement of Deaf People in Wisconsin: 2017

Postsecondary experiences of deaf people vary widely across the nation. National reports about educational attainment and employment are available at nationaldeafcenter.org (Garberoglio, Cawthon, & Bond, 2016; Garberoglio, Cawthon, & Sales, 2017). This report provides current estimates of postsecondary achievement in Wisconsin. We used 5-year estimates of data from the American Community Survey (ACS), a national survey conducted by the U.S. Census Bureau, to generate the findings in this report. More information about this dataset and the analyses are shared in the Methods section at the end of this report.This document was developed under a grant from the U.S. Department of Education, OSEP #HD326D160001.
