Numerous studies have investigated the impact of class size on student outcomes. This analysis contributes to this discussion by examining the impact of class size on student outcomes in higher education. Additionally, this paper investigates the importance of student load (total number of students taught across all courses) in educational outcomes. We find that both class size and student load...

In a meta-analysis of 25 studies, the relationship of both specific types of negative life events and the total number of experienced events to depression in old age was studied. Almost all negative life events appeared to have a modest but significant relationship with depression. The total number of negative life events and the total number of daily hassles appeared to have the strongest rela...

The aim of this study was to investigate the extent to which tactile information that is unavailable for full conscious report can be accessed using partial-report procedures. In Experiment 1, participants reported the total number of tactile stimuli (up to six) presented simultaneously to their fingertips (numerosity judgment task). In another condition, after being presented with the tactile ...

Relations between children's imaginary companion status and their engagement in private speech during free play were investigated in a socially diverse sample of 5-year-olds (N=148). Controlling for socioeconomic status, receptive verbal ability, total number of utterances, and duration of observation, there was a main effect of imaginary companion status on type of private speech. Children who...

A Sudoku grid is a constrained Latin square. In this paper a reduced Sudoku grid is described, the properties of which differ, through necessity, from that of a reduced Latin square. The Sudoku symmetry group is presented and applied to determine a mathematical relationship between the number of reduced Sudoku grids and the total number of Sudoku grids for any size. This relationship simplifies...

This study explored how social pressure related to parental preference for the sex of their children affects fertility. Pre-war and post-war generations were compared using individual level data previously collected in Japan in 2002. In the pre-war generation, if the first child was a daughter, the total number of children tended to increase not only when the mother preferred a son, but also wh...

The present study investigated associations between maternal relationship instability patterns and children's behavioral and emotional functioning in middle childhood in a representative sample of low-income urban families (N = 891). Data from the Three-City Study tracked maternal partnerships through the child's life, assessing total marital and cohabiting relationship transitions and delineat...

Analysis of new data on the relationship between and premiums and coverage in the individual insurance market and health risk shows that actual premiums paid for individual insurance are much less than proportional to risk, and risk levels have a small effect on obtaining coverage. States limiting risk rating in individual insurance display lower premiums for high risks than other states, but s...

I examined the relation between courtship and mate choice in convict cichlids by presenting females with the option of courting and spawning with one of two males that were isolated from each other. I quantified the amount of courtship performed by females towards males they selected as mates and males they rejected, and the amount of courtship performed by each male towards the female. I measu...
