Youth from single-parent families report lower educational aspirations than those from two-parent families. This study explored
the influence of background factors (gender, grade, parental education and SES), parental involvement with education, academic self-concept, and peer influences on educational aspirations. The participants
were Canadian adolescents; 2751 from two parent and 681 from single-parent families. ANOVA results showed that adolescents
from single-parent families scored significantly lower than adolescents from intact families on educational aspirations, and
other predictor variables. Hierarchical regression analysis showed that the pattern of relationships between educational aspirations
and other factors was very similar for adolescents from both types of families; namely academic self-concept significantly
predicted educational aspirations. The family involvement and background factors predicted educational aspirations via academic
self-concept. Having academically oriented peers was especially beneficial to adolescents from single-parent families. Implications
for intervention programs are discussed.
The research was supported by a Social Sciences and Humanities Research Council of Canada Grant.

Validation studies of the new DentalPrint software were carried out with experimental bite marks in pigskin. The bite marks were digitally photographed according to the ABFO guidelines for evidence collection. Dental casts used in the experiment were scanned in 3D and 2D, and comparison overlays were generated using DentalPrint and Adobe Photoshop software, respectively. Digitized photographs of the experimental bite marks and the biting edges obtained in the overlays were compared by two different examiners to analyze the impact of training and experience with the two methods. Receiver operating characteristic (ROC) analysis, sensitivity, specificity, and 95% confidence intervals for each cutoff point were calculated. The expert examiner using DentalPrint obtained the best results, with an area under the ROC curve of 0.76 (SE=0.057; CI at 95%=0.652-0.876). Fairly high specificity values were found for DentalPrint, and the best results were obtained for the cutoff value that discriminated between the examiner's response "biter" and the rest of the possible (specificity 97.9%, CI at 95%=93.2%-99.6%). Therefore, the results presented here indicate that DentalPrint is a useful, accurate tool for forensic purposes, although further research on the comparison process is needed to enhance the validity of bite mark analysis. 相似文献
