Muller, Thomas; Frauendiener, Jorg – European Journal of Physics, 2012
In a first course in general relativity, the Schwarzschild spacetime is the most discussed analytic solution to Einstein's field equations. Unfortunately, there is rarely enough time to study the optical consequences of the bending of light for some advanced examples. In this paper, we present how the visual appearance of a thin disc around a…

Muller, Thomas; Frauendiener, Jorg – European Journal of Physics, 2011
In a first course of general relativity, it is usually quite difficult for students to grasp the concept of a geodesic. It is supposed to be straight (auto-parallel) and yet it "looks" curved. In these situations, it is very useful to have some explicit examples available which show the different behaviour of geodesics. In this paper, we present…

Boblest, Sebastian; Muller, Thomas; Wunner, Gunter – European Journal of Physics, 2011
The "twin paradox" of special relativity offers the possibility of making interstellar flights within a lifetime. For very long journeys with velocities close to the speed of light, however, we have to take into account the expansion of the universe. Inspired by the work of Rindler on hyperbolic motion in curved spacetime, we study the worldline…

Lochmiller, Chad R.; Sugimoto, Thomas J.; Muller, Patricia A. – Regional Educational Laboratory Appalachia, 2016
The purpose of this descriptive study was to determine the rates of retention, mobility, and attrition for classroom teachers in Kentucky public schools, as well as how those rates might vary by various teacher and school characteristics. The study looks at retention, defined as teachers returning to their same classroom ("stayers");…

Lochmiller, Chad R.; Sugimoto, Thomas J.; Muller, Patricia A.; Mosier, Gina G.; Williamson, Steven E. – Regional Educational Laboratory Appalachia, 2016
Kentucky is using dual enrollment as one strategy to improve access to postsecondary education for its high school students, particularly after passage of Kentucky Senate Bill 1 in 2009, which focused on improving college and career readiness. The Regional Educational Laboratory (REL) Appalachia undertook a descriptive study of participation in…

Beyer, Thomas; Postert, Christian; Muller, Jorg M.; Furniss, Tilman – Child Psychiatry and Human Development, 2012
In a four-year longitudinal study, changes in and continuity of behavioral and emotional problems were examined in 814 subjects from kindergarten to primary school. Mental health problems were assessed by means of the Child Behavior Checklist (CBCL). The distribution of the CBCL broadband groups revealed a high level of continuity of internalizing…

Geyer, Thomas; Shi, Zhuanghua; Muller, Hermann J. – Journal of Experimental Psychology: Human Perception and Performance, 2010
Three experiments examined memory-based guidance of visual search using a modified version of the contextual-cueing paradigm (Jiang & Chun, 2001). The target, if present, was a conjunction of color and orientation, with target (and distractor) features randomly varying across trials (multiconjunction search). Under these conditions, reaction times…

Muller, Thomas – 1975
This is the second in a series of reports concerned with evaluating the impacts of land development. This report discusses in considerable depth and detail how development affects the revenues and expenditures of local government. Questions include the following: (1) Will new development inflate the demand for public services and facilities in…

Muller, Thomas – 1993
The latest immigration surge, which began in the 1960s, has facilitated urban renewal by strengthening small businesses, providing low-wage labor, and maintaining the population base needed to sustain a high level of economic activity. In spite of the contributions of immigrants, American central cities continue to face serious economic…

Muller, Hermann J.; Geyer, Thomas; Zehetleitner, Michael; Krummenacher, Joseph – Journal of Experimental Psychology: Human Perception and Performance, 2009
Three experiments examined whether salient color singleton distractors automatically interfere with the detection singleton form targets in visual search (e.g., J. Theeuwes, 1992), or whether the degree of interference is top-down modulable. In Experiments 1 and 2, observers started with a pure block of trials, which contained either never a…

Geyer, Thomas; Muller, Hermann J.; Krummenacher, Joseph – Journal of Experimental Psychology: Human Perception and Performance, 2007
Two experiments examined cross-trial positional priming (V. Maljkovic & K. Nakayama, 1994, 1996, 2000) in visual pop-out search. Experiment 1 used regularly arranged target and distractor displays, as in previous studies. Reaction times were expedited when the target appeared at a previous target location (facilitation relative to neutral…

Muller, Thomas; And Others – 1980
This report focuses on demographic and economic changes affecting urban households during the 1980s. Statistics regarding birth, fertility and mortality rates, marriage and divorce, and household formation are presented. Metropolitan and interregional trends in mobility are examined by racial, income and age groups. Growth rates of the national…

Muller, Thomas E. – Journal of Nutrition Education, 1984
Determined whether shoppers would use nutrition information when making in-store choices among brands of five packaged products. Also determined whether information used would be affected by the number of nutrients appearing on signs displayed in the store, and/or by the perceived importance of the set of nutrients presented.

Levin, Betsy; Muller, Thomas – 1973
This study documents the revenue and expenditure patterns for categories of school districts and for individual school districts. The fiscal impact of the current system, the nature and extent of fiscal disparities, and the factors that contribute to the disparities are examined. An attempt is made to distinguish between disparities among…

Postert, Christian; Averbeck-Holocher, Marlies; Beyer, Thomas; Muller, Jorg; Furniss, Tilman – Child Psychiatry and Human Development, 2009
"DSM-IV" and "ICD-10" have limitations in the diagnostic classification of psychiatric disorders at preschool age (0-5 years). The publication of the "Diagnostic Classification 0-3 (DC:0-3)" in 1994, its basically revised second edition ("DC:0-3R") in 2005 and the "Research Diagnostic Criteria-Preschool Age (RDC-PA)" in 2004 have provided several…
