Experimental Study of Bite Mark Injuries by Digital Analysis

Abstract: This study was based on a morphometric analysis of bite marks starting from the quantitative definition of the anterior teeth by the geometric acquisition of the “injuries,” using bite marks impressed on pig skin and plastic. Each mark was photographed and acquired. A dedicated program automatically supplied the values of the shape factors and the areas of the pattern geometric figures. The values obtained for the homologous samples were compared to the heterologous values. Statistical comparison was made of the sets by linear regression, determining the correlation coefficient and the determination coefficient for each value. Results showed only 4.8% and 2% of overlap between homologous and heterologous values. This study was carried out in attempting to quantitatively define the anterior teeth of the human dentition and the procedure described and the results obtained support the advantage of morphometric studies and computer‐aided programs in this study of bite marks.

Youth Development Outcomes of the Camp Experience: Evidence for Multidimensional Growth

Three thousand, three hundred and ninety-five families, whose child attended one of 80 different day or resident summer camps for at least one week, completed customized questionnaires that measured growth from precamp to postcamp in four domains: Positive Identity, Social Skills, Physical & Thinking Skills, and Positive Values & Spirituality. Parents, children, and camp staff reported significant positive change in these four domains; more than would be expected by maturation alone. Most gains were maintained or showed additional growth six months later. Few of the camp's structural elements correlated with growth, nor did striking gender, age, or ethnicity differences emerge. The study highlights the particular strengths of camp as an educational institution and social movement and suggests that different variations of summer camp can provide potent developmental experiences.
