This paper uses the widespread variation across states in the timing of adoption of tougher drunk driving laws that set very low legal blood alcohol limits for drivers under age 21--"zero tolerance" (ZT) laws--to provide new evidence on the causal effect of alcohol use on youth suicide. ZT laws reduced heavy episodic drinking by underage men, with…

In the study reported here, I examined the diagrams that mathematically capable high school students produced in solving applied calculus problems in which a diagram was provided in the problem statement. Analyses of the diagrams contained in written solutions to selected free-response problems from the 1996 BC level Advanced Placement Calculus…

The Adaptive/Maladaptive Perfectionism Scale (AMPS) for children measures different dimensions of perfectionism. In this study, subscales derived from the AMPS were compared with results of the Piers-Harris Self-Concept Scale (PHSCS) in a sample of fourth- and fifth-grade students (9 to 11 years old). The AMPS dimensions accounted for significant…

The peer context plays an important role in adolescents' views of math and social domains. (Contains 1 table and 2 figures.)

This study examined why female adolescents choose to opt out of the math pipeline during high school more often than males, which has implications for their long-term careers. (Contains 3 figures.)

Student perceptions of what constitutes appropriate and inappropriate classroom behavior are affected by who is being asked. (Contains 3 tables.)

Hierarchical linear modeling (HIM) is an approach used in data analysis to better understand how program outcomes are affected by the "nested" nature of data collected in many studies. An outcome can be considered variables such as an individual's self-efficacy, social skills, or more targeted outcomes such as demonstrated reading and mathematical…

College students rank "raising a family" as one of their primary values (American Council on Education and University of California, 2003). Yet, little is known about their understanding of the respective roles of motherhood and fatherhood. Feminism, dual career marriages, and more egalitarian role models may have altered adherence to…

This study compared the characteristics of girls in the juvenile justice system with their male counterparts in selected Texas counties. A relatively higher proportion of girls who are in trouble with the law experienced ineffective parental control as compared to delinquent boys. They also experienced more problems in family, school, and with…

The purpose of this article was to model United States Medical Licensing Examination (USMLE) Step 2 passing rates using the Cox Proportional Hazards Model, best known for its application in analyzing clinical trial data. The number of months it took to pass the computer-based Step 2 examination was treated as the dependent variable in the model.…

Datasets are often under-exploited by institutions, yet they contain evidence that is potentially of high value for planning and decision-making. This article shows how institutional data were used to determine whether the demographic background of students might have an influence on their performance: this is a matter of particular interest where…

The purpose of the present study was to investigate the relationship between personal variables of physical education students and their attitudes towards participation of children with disabilities and self-efficacy (SE) in teaching students with disabilities in regular classes. A total 153 PE majors (95 females and 58 males) participated in the…

Academic enabling behaviors play a significant role in the development of academically competent students. Academic enablers are behaviors that facilitate learning such as social skills, study skills, motivation, and engagement. In this study, teacher and student ratings were used to describe the academic enablers of a nationally representative…

We evaluated the extent to which aggressive victims show unique developmental pathways that are different from those of passive victims, bullies, and uninvolved children. A total of 1,722 children were followed from 4th grade to 6th grade, and the prevalence and stability of each group were assessed. Aggressive victims became less prevalent and…

Majority-race (black or white) elementary school children with and without a minority friend (black or white) in their classroom were compared on measures of social, behavioral, and affective characteristics. Analyses focused on 260 4th through 6th grade students who were racial majorities in their classrooms and had at least one reciprocated…
