Greeley, CO, United States

The University of Northern Colorado is a coeducational public institution of higher education in Greeley, Colorado, USA, with satellite centers in Loveland, Colorado Springs and the Lowry neighborhood of Denver. It is the fifth-largest university in the state by total enrollment, behind the University of Colorado - Boulder, Colorado State University, Metropolitan State University, and the University of Colorado - Denver.Established in 1889 as the State Normal School of Colorado, the university has a strong background in teacher education. The university offers over 100 undergraduate programs in the arts, science, humanities, business, human science, and education. Undergraduate degrees are typically four year programs and degree programs have a strong emphasis in liberal arts education. The university offers nearly 50 graduate programs primarily in education. Academic programs are distributed among six colleges. Wikipedia.

The Late Pleistocene Antarctic temperature variation curve is decomposed into two components: "cyclic" and "high frequency, stochastic." For each of these components, a mathematical model is developed which shows that the cyclic and stochastic temperature variations are distinct, but interconnected, processes with their own self-organization. To model the cyclic component, a system of ordinary differential equations is written which represent an auto-oscillating, self-organized process with constant period. It is also shown that these equations can be used to model more realistic variations in temperature with changing cycle length. For the stochastic component, the multifractal spectrum is calculated and compared to the multifractal spectrum of a critical sine-circle map. A physical interpretation of relevant mathematical models and discussion of future climate development within the context of this work is given. Key Points Temperature curve is decomposed into two parts: "cyclic" and "stochastic" Two mathematical models are created and studied "Cyclic" and "stochastic" components are two types of self-organization © 2014.

While e-book sales continue to increase, electronic textbooks are not very popular with college students. This may be due to the fact that e-textbooks are read for different reasons and with different strategies than are e-books. Although previous research has documented this lack of preference for e-textbooks, student performance and use of electronic texts has yet to be thoroughly investigated, especially in naturalistic settings. This study examines students' use and performance on a variety of print and electronic formats in both laboratory and at-home conditions. Although students scored similarly across formats and conditions, reading time was significantly higher in the electronic conditions with this difference increasing for the home conditions. Similarly, self-reports of multi-tasking were significantly higher for electronic conditions in the home condition, possibly accounting for the disparities in reading time. We conclude by urging caution in the rush to assume that electronic textbooks are equivalent substitutes for traditional textbooks and argue for further investigation into the unique ways that students may interact with electronic texts to promote more effective design. © 2012 Elsevier Ltd.

Objectives: This study examined the impact of parental alcohol misuse and family environment on young adults' drinking and behavioral problems in secondary schools. Methods: The study used a multivariate logistic regression longitudinal analysis. The effects of parental and young adult alcohol use and family environment on school behavioral problems were estimated over 20 years from 1984 to 2004. Sample: Data were drawn from the National Longitudinal Surveys of Youth (NLSY79), a representative sample of the general population of the United States, and the surveys of Mother-Child and Young Adults (MCYA): mothers (N = 5634), fathers (N = 5007) and young adults (N = 4648). Results: Parental alcohol misuse increased the risk of alcohol misuse in offspring. There was a threefold rise in school behavior problems among youth from family environments in which the biological father was a heavy drinker and the marital quality of the biological parents was reported as poor and the home life was characterized by high conflict, argumentativeness, disruption and ineffectual parental monitoring as well as by low family cohesion. Conclusions: There is a need for prevention and intervention programs oriented toward reducing alcohol misuse among secondary school students. Preventive strategies should incorporate substance use, involve families and be applicable to both within and outside the school environment. © 2014 Informa UK Ltd. Source

The Chemical Concepts Inventory (CCI) is a multiple-choice instrument designed to assess the alternate conceptions of students in high school or first-semester college chemistry. The instrument was published in 2002 along with an analysis of its data from a test population. This study supports the initial analysis and expands on the psychometric data available. The CCI was given to over 2500 students from four universities. Data were analyzed using classical test theory and Rasch model methods. The classical test theory analysis found the CCI to have acceptable internal consistency (Cronbach's α = 0.73, pretest, and 0.76, posttest) and good test-retest reproducibility (Pearson correlation = 0.79, posttest). Most items were found to have good difficulty and discrimination values; however, a few had values that may warrant further evaluation. The Rasch analysis showed that the instrument and the items nicely fit the Rasch model. The data showed good separation reliability and that the instrument overall is at an appropriate level for the population. However, several gaps were found along the range of item difficulties, leading to less accurate estimations of student abilities. Overall, the CCI was found to be suitable for the large-scale assessment of students' alternate conceptions. © 2013 The American Chemical Society and Division of Chemical Education, Inc. Source

Involving stakeholders can greatly impact evaluation results. The Delphi method, a consensus-building tool, is a promising process to promote and encourage involvement from all stakeholders during the evaluation framing process. The Delphi method removes geographic challenges and time boundaries allowing all stakeholders to participate. The Delphi method uses a series of surveys interspersed with controlled feedback designed to gather information and build consensus without requiring face-to-face meetings. Two different formats of the Delphi method, a paper-and-pencil, postal-mail version and a web-based, real-time computer version are compared in this study. Both versions of the Delphi were administered to a non-profit community based organization as part of framing an evaluation. Participation rates were better with the paper-pencil version. The quantity and quality of data collected were comparable in both versions. © 2009 Elsevier Ltd. All rights reserved. Source
