A study was undertaken to implement a series of chance games and activities in a Year 7 classroom, and investigate the students' knowledge about probability concepts, as well as their attitudes to chance. Initially, the project involved selecting a set of appropriate learning activities to develop key probability concepts which are integral to the…

Aim: The aim of this study was to elucidate factors related to the high rate of mental health disorders seen in those with impaired hearing, including social factors and audiological measures. Method: A representative sample of 95 pupils (47 females, 48 males; mean age 11y 1mo, range 6y 5mo to 16y, SD 2y 7mo) with hearing impairments of at least…

Clinical research has found a strong association between negative affect and returning to alcohol use after a period of abstinence. Yet little is known about the probability of a lapse given a particular level of negative affect or whether there is a reciprocal relationship between negative affect and alcohol use across time. The goal of the…

Objective: The authors identified the principal components of bar and nightclub expectancy in college students and the associations between these factors and the risk behavior of nightclubbing. Participants: A total of 4,384 undergraduates enrolled at a large, public university participated. Methods: In the first phase (July-September 2007), the…

Purpose: The purpose of this paper is to measure the relative effect of relevant explanatory variable on smoking tendency and smoking intensity. Design/methodology/approach: Using survey data collected by the Israeli Bureau of Statistics in 2003-2004, a probit procedure is estimated for analyzing factors that affect the probability of being a…

Using social network analysis, we investigated the characteristics of social networks composed of positive relationships (positive network: PN) and negative relationships (negative network: NN) in classrooms of Japanese 3- and 4-year-olds. Analysis of "density" showed that PNs were denser than NNs among 4-year-olds but that this was not…

Prior research indicates that the married enjoy higher levels of well-being than the unmarried, including unmarried cohabiters. Yet, comparisons of married and unmarried persons routinely exclude partnered gays and lesbians. Using a large probability sample, this study assessed how the well-being of partnered gays and lesbians (282) compares with…

Ecuador's 2008 Constitution--and a subsequent law on higher education passed in its wake--effectively suspended student fees for public universities. The goal of this reform was to increase equality of opportunity. In this article I use newly-available individual-level retrospective information from the 2001 Census to explore gender and ethnic…

This article describes a one-week introduction to stochastic groundwater modeling, intended for the end of a first course on groundwater hydrology, or the beginning of a second course on stochastic hydrogeology or groundwater modeling. The motivation for this work is to strengthen groundwater education, which has been identified among the factors…

An extensive database of exam scores is studied to determine the effects of a grading policy that drops the lowest exam score. We find evidence that some students engage in strategic behavior, either by understudying for one of the exams or missing one altogether, but the vast majority of students show no evidence of strategic behavior. We also…

Clinical decision-making is challenging mainly because of two factors: (1) patient conditions are often complicated with partial and changing information; (2) people have cognitive biases in their decision-making and information-seeking. Consequentially, misdiagnoses and ineffective use of resources may happen. To better support clinical…

A growing body of research examines the effects of state affirmative action bans on domestic minority students' application and admission rates. This study expands previous research, considering how Texas's implementation of a race-neutral percent plan influenced admission opportunities for two understudied groups: foreign students and in-state…

Objective: The purpose of the study was to explore heterogeneity and differential treatment outcome among a sample of patients with binge eating disorder (BED). Method: A latent class analysis was conducted with 205 treatment-seeking, overweight or obese individuals with BED randomized to interpersonal psychotherapy (IPT), behavioral weight loss…

The current study examined to what extent information in long-term memory concerning the distribution of phoneme clusters in a language, so-called long-term phonotactic knowledge, increased the capacity of verbal short-term memory in young language learners and, through increased verbal short-term memory capacity, supported these children's first…

Several organizations have highlighted the importance of preparing teachers to teach students mathematics using appropriate technology (e.g., Association of Mathematics Teacher Educators, 2006; International Society for Technology in Education, 2008). This article provides examples from teacher education materials that were developed using an…
