Submissions to an online homework tutor were analyzed to determine whether they were copied. The fraction of copied submissions increased rapidly over the semester, as each weekly deadline approached and for problems later in each assignment. The majority of students, who copied less than 10% of their problems, worked steadily over the three days…

Background: Despite extensive efforts, the causes of autism remain unknown. Advancing paternal age has been associated with various neurodevelopmental disorders. We aim to investigate three unresolved questions: (a) What is the association between paternal age and autism spectrum disorders (ASD)?; (b) Does paternal age moderate the genetic and…

Many studies have shown that pharmaceutical marketing affects prescribing choices. Studies that have assessed the effects of educational interventions on perceptions of pharmaceutical promotion have found mixed results. This study assesses the short-term effects of an educational intervention about marketing tactics on the attitudes and fund of…

This project analyzes the organizational behavior of the University of Texas System. The University of Texas System is comprised of nine academic and six health institutions. The University of Texas System has over 85,000 employees; the student enrollment is 202,240 with a budget of $2.25 billion dollars. This project has a total of four parts and…

The intensive use of interactive media has led to assertions about the effect of these media on youth. Rather than following the assumption of a distinct Net generation, this study investigates diversity in interactive media use among youth. Results from a pilot study show that contemporary youth can be divided into clusters based on the use of…

The present study examined the role of adolescents' self-esteem and perceptions of family and classroom contexts on their domain specific self-perceptions. 345 Greek junior high school adolescents aged 14-16 completed measures of domain specific self-perceptions, self-esteem, parenting styles and classroom climate. Hierarchical regression analyses…

This article concerns individual differences in the associative meaning of psychological concepts. Associative meaning may be assessed with prototype methodology, which yields a list of features of the concept ordered according to their rated importance. Our theory concerns individual differences in a concept's associative meaning: A personal…

Stander and colleagues, in 1989, noted that change in specialization may be caused by two distinct but potentially complementary processes: (a) a change in group composition, where change in specialization is the product of the attrition of offenders who vary systematically in their tendency to specialize; and (b) a change in the tendency to…

This paper is founded upon the premise that "common sense" understandings about boys persist within schools and, given this continuing circulation of such understandings, advocates the need to critique such conceptualising. It does so on the grounds that such understandings, and the essentialist discursive knowledges informing these, fail to take…

Many experiential educators assume that participation in outdoor recreation creates an awareness and commitment to the environment through direct experience. This research summary looks to whether the research supports such an assumption. Specifically it reviews the key literature on this topic, examines the various classifications of outdoor…

Analysis of survey data collected from 6,520 students at a large Midwestern University affirmed that financial knowledge is a significant factor in the credit card decisions of college students but not entirely in expected ways. Results of a double hurdle analysis indicated that students with relatively higher levels of financial knowledge were…

Evolutionary psychologists explore the adaptive function of traits and behaviors that characterize modern Homo sapiens. However, evolutionary psychologists have yet to incorporate the phylogenetic relationship between modern Homo sapiens and humans' hominid and pongid relatives (both living and extinct) into their theorizing. By considering the…

Background: Emotion regulation (ER) has been conceptualized as an ongoing process of the individual's emotion patterns in relation to moment-to-moment contextual demands. In contrast to traditional approaches of descriptively quantizing ER, we employed a dynamic approach to ER by examining key transitions in infants of clinically depressed and…

The three algorithms most frequently selected by behavior-analytic researchers to compute interobserver agreement with continuous recording were used to assess the accuracy of data recorded from video samples on handheld computers by 12 observers. Rate and duration of responding were recorded for three samples each. Data files were compared with…

Recent evidence demonstrated that dopamine within the nucleus accumbens mediates consolidation of both associative and nonassociative memories. However, the specific contribution of the nucleus accumbens subregions, core and shell, and of D1 and D2 receptors subtypes has not been yet clarified. The aim of this study was, therefore, to directly…
