The subject matter presented in this article can be used in the classroom to enrich the learning experience of students taking a course that includes a unit on combinatorics, such as discrete mathematics, graph theory, or probability. In order to provide such students with the background needed to appreciate the significance of the generalization…

Little prior research has examined children's interpersonal perceptions of peers from a social relations model framework. This study examines the degree of actor and partner variances, as well as generalised and dyadic reciprocities, in a sample of 351 sixth graders' peer nominations of different forms and functions of aggression and aspects of…

The influence of three components of temperament (activity level, impulsivity, and soothability) on children's friendships was investigated. Children (40 girls, 35 boys) aged 43 to 69 months responded to a sociometric interview and teachers provided temperament ratings. The probability of children choosing particular classmates as friends was…

Research studies uniformly find that, on average, about 25% of teen dating relationships contain violent elements. Research with pregnant and parenting teens show…

Context: Psychosocial exposures commonly show large variation over time and are usually assessed using multi-item Likert indices. A construct requiring a five-item Likert index could possibly be replaced by a single visual analogue scale (VAS). Objective: To: a) evaluate validity and relative reliability of a single VAS compared to previously…

The rise of molecular genetics is having a pervasive influence in a wide variety of fields, including research into neurodevelopmental disorders like dyslexia, speech and language impairments, and autism. There are many studies underway which are attempting to determine the roles of genetic factors in the aetiology of these disorders. Beyond the…

A sense of direction (SOD) computes the body's facing direction relative to a reference frame grounded in the environment. The authors report on three experiments in which they used a heading-recall task to tap the functioning of a SOD system and then correlated task performance with self-reported SOD as a convergent test of the task's construct…

Should instruments, such as Likert-type scales, contain both positively worded and negatively worded items within the same scale (i.e. mixed format)? Recent evidence suggests that the use of scales with a mixed format can adversely affect the psychometric properties of scales. In particular, the mean item response to the positively worded items…

A brief instrument to assess risk of injury was applied retrospectively for 2 years and prospectively for 1 year to all people living in a large ICF/MR.
