This study proposes transformation functions and matrices between coefficients in the original and reparameterized parameter spaces for an existing linear-linear piecewise model to derive the interpretable coefficients directly related to the underlying change pattern. Additionally, the study extends the existing model to allow individual…

Background: Although students with disabilities are enrolling in higher education in larger numbers than ever before, they are still underrepresented in colleges and universities, particularly among four-year institutions. College choice has been explored across multiple facets, but limited research has examined the college choice processes of…

Public attitude surveys provide invaluable data for assessing perceptions, values, and attitudes across societies and over time. Ideally, respondents feel secure to disclose accurate information (avoiding reporting bias and item non-response) in the context of a face-to-face interview. Yet, survey research seldom accounts for peer effects caused…

Address-based sampling (ABS) refers to the use a list of addresses derived from the U.S. Postal Service's Computerized Delivery Sequence File as a sampling frame. While most residential addresses are included on an ABS frame, it still suffers from undercoverage. Undercoverage is problematic only if the uncovered units have different attributes…

Child labor is a sobering reality in a modern society, when it has been practiced over numerous decades and has led to such inhumane consequences for children. Due to poverty, poor family conditions, socio-economic fragility, phenomena like child labor have been observed globally. In terms of South Asian countries, in many instances it is a source…

In prior work, we fit the mixture Rasch model to item responses from a fractions survey administered to a nationwide sample of middle grades mathematics teachers in the United States. The mixture Rasch model located teachers on a continuous, unidimensional scale and fit best with 3 latent classes. We used item response data to generate initial…

The purpose of this research was to identify the comfort levels of professionals with AI in various humanlike roles. A survey of 787 full-time working adults showed that more active AI users are comfortable with AI in many humanlike roles, such as a teammate or a performance coach. Less active AI users, however, are uncomfortable with AI in these…

Not knowing the population size is a common problem in data-limited contexts. Drawing on work in Sierra Leone, this short take outlines a four-step solution to this problem: (1) estimate the population size using expert interviews; (2) verify estimates using interviews with participants sampled; (3) triangulate using secondary data; and (4)…

Conducting research among hard-to-reach populations is a difficult endeavor because some of their characteristics are known to be associated with survey nonresponse and panel attrition. In the case of the Parchemins study, which followed undocumented migrants over their process of regularization and during the first years of regularized life in…

Objective: To characterize the context, patterns, and correlates of sedentary behavior (SB) in university students. Participants: A total of 95 adults (41% men) enrolled in 34 different undergraduate majors. Methods: SB was assessed by questionnaire and accelerometer. Results: Objective SB and moderate-to-vigorous physical activity (MVPA)…

Adaptive survey design refers to using targeted procedures to recruit different sampled cases. This technique strives to reduce bias and variance of survey estimates by trying to recruit a larger and more balanced set of respondents. However, it is not well understood how adaptive design can improve data and survey estimates beyond the…

We discuss methods that can improve response rates in large-scale cross-sectional and longitudinal studies. Regardless of the specific study topic, sample member population, or method of contact, data collections should be designed with certain core principles in mind: legitimizing the study to prospective participants; presenting study…

This paper reports on students' experiences of describing and representing variation in hypothetical data. Fifty-six students (8-9 years-old) experienced collecting and working with quantitative data for two years as part of a STEM education project. The task described here was an end-of-year survey question, with three parts about a hypothetical…

Adult literacy skills are critical assets of individuals as well as societies in terms of economic (e.g., human capital) and social well-being. Thus, it is important to monitor the long-term trends and sources of skill gain/loss. Yet, temporal sources of adult literacy skill variation are understudied. The current study analyzed three comparable,…

How might a theory of communicative rationality be applied to policymaking to secure the morally justifiable administration of public education? In answer, Darron Kelly uses conceptual resources found in Habermasian practical discourse to outline development of a survey instrument. The survey is designed to measure constituent satisfaction with…
