Educational video games provide an opportunity for students to interact with and explore complex representations of academic content and allow for the examination of problem-solving strategies and mistakes that can be difficult to capture in more traditional environments. However, data from such games are notoriously difficult to analyze. This…

Students with different achievement goal orientations have different approaches towards learning and studying. There is a widespread interest to find an easy access into learning spaces for those students who have low motivation with fear of failure and academic withdrawal. Mobile learning offers an easily accessible chance with low threshold to…

Vocal disorders are a very common occupation-related disease in teachers, though it has never been given enough attention in China. As a result, the occupational health care of professional voice users is surprisingly, undeveloped compared to the attention given to occupational hearing disorders or many other occupational symptoms.

This paper outlines the development of a "Three-dimensional Empowerment Framework", and…

The present study was aimed at investigating the relationships between students' perceived classroom achievement goals, school engagement and substance use in terms of smoking and drinking, and at investigating gender differences regarding these issues in a sample of 1,239 Norwegian 10th grade students. A multivariate analysis showed that…

There is evidence supporting the social and cognitive benefits of music education. However aspects of music practice, such as an increase in frequency and intensity of practice, are associated with playing-related musculoskeletal problems in adult musicians, though with limited evidence in children. The aim of this study was to describe the music…

Children's ability to manage the expression of sadness is critical to their development and adjustment. Although parents have been the primary focus of research examining sadness socialization, many acknowledge the influence of other agents such as children's peers. The present research evaluated one type of emotion socialization--reactions to…

"Entre Familia: Reflejos de Salud" was a successful family-based randomized controlled trial designed to improve dietary behaviors and intake among U.S. Latino families, specifically fruit and vegetable intake. The novel intervention design merged a community health worker ("promotora") model with an entertainment-education…

The benefits of physical activity and active play for children and young people are well established. However, there is a lack of physical activity research involving children and young people with intellectual disabilities. This study investigated habitual physical activity and recess play behaviour in 70 5- to 15-year-old participants with…

In the current study of 353 science and engineering faculty members, we examined whether three types of gender-based mistreatment might "chill" individuals' perceptions of the professional climate, which might in turn undermine satisfaction with their jobs. We also tested gender differences in these relationships. Results indicated that…

The experience of discrimination is a complex phenomenon. At present, there are few studies that have captured the experience of discrimination on a predominately white university campus. This study was designed to investigate the association between perceived discrimination and self-reported health outcomes among university students in Southwest…

A model of negative affect and alcohol use was replicated on a sample of African-American high school students. Participants (N = 5,086) were randomly selected from a previously collected data set and consisted of 2,253 males and 2,833 females residing in both rural and urban locations. Multivariate analysis of covariance and structural equation…

The objective of my dissertation is to create a general approach to evaluating IS/IT projects using Real Option Analysis (ROA). This is an important problem because an IT Project Portfolio (ITPP) can represent hundreds of projects, millions of dollars of investment and hundreds of thousands of employee hours. Therefore, any advance in the…

We examined substance use onset and associations with pregnancy by age 15 years. Participants were girls ages 15 years or younger (weighted n = 8319) from the 1999-2003 Youth Risk Behavior Surveillance System (YRBS). Multivariable logistic regression examined pregnancy as a function of substance use onset (i.e., age 10 years or younger, 11-12,…

In this article, the authors talk about variation and how variation between measurements may be reduced if sampling is not random. They also talk about replication and its variants. A replicate is a repeated measurement from the same experimental unit. An experimental unit is the smallest part of an experiment or a study that can be subject to a…
