Transitions in drinking behaviors across the college years: A latent transition analysis [PDF]
Addictive Behaviors, 2019 College student alcohol use remains a considerable concern. While many colleges provide universal interventions surrounding matriculation, trends indicate alcohol use increases over the college years. This study utilized a person-centered approach to examine changes in drinking across college and predictors (expectancies, attitudes, norms, and gender ...

The endpoint of the electroweak phase transition [PDF]
, 1997 The 3d SU(2)-Higgs model is used to find the critical Higgs mass above which the first order phase transition ends. One method is focused on the disappearance of the two-state signal of the scalar condensate (vanishing of the latent heat). Another method

Fraction Errors in a Digital Mathematics Environment: Latent Class and Transition Analysis
Journal of Numerical Cognition, 2019 Student struggles with fractions are well documented, and due to fractions’ importance to later mathematics achievement, identification of the errors students make when solving fraction problems is an area of interest for both researchers and teachers ...

Fingerprinting models of first-order phase transitions by the synergy between collider and gravitational-wave experiments [PDF]
, 2018 We investigate the sensitivity of future space-based interferometers such as LISA and DECIGO to the parameters of new particle physics models which drive a first-order phase transition in the early Universe.

Finite size effects at phase transition in compact U(1) gauge theory [PDF]
, 1997 We present and discuss the results of a Monte-Carlo simulation of the phase transition in pure compact U(1) lattice gauge theory with Wilson action on a hypercubic lattice with periodic boundary conditions.

Student perspectives on the relationship between a curve and its tangent in the transition from Euclidean Geometry to Analysis [PDF]
, 2008 The tangent line is a central concept in many mathematics and science courses. In this paper we describe a model of students’ thinking – concept images as well as ability in symbolic manipulation – about the tangent line of a curve as it has developed ...

Alternative Models of Dynamics in Binary Time-Series-Cross-Section Models: The Example of State Failure [PDF]
, 2001 This paper investigates a variety of dynamic probit models for time-series-cross-section data in the context of explaining state failure. It shows that ordinary probit, which ignores dynamics, is misleading.

Learning scientific reasoning: A latent transition analysis
Learning and Individual Differences, 2021 Primary education in many countries enables children to learn the scientific reasoning skills of hypothesizing, experimenting, interpreting data and drawing conclusions. Research has shown that these component skills develop at a different pace and with substantial variation among same-age children.

Factor-Driven Two-Regime Regression
, 2020 We propose a novel two-regime regression model where regime switching is driven by a vector of possibly unobservable factors. When the factors are latent, we estimate them by the principal component analysis of a panel data set.
