Highly parallel SNP genotyping platforms have been developed for some important crop species, but these platforms typically carry a high cost per sample for first-time or small-scale users. In contrast, recently developed genotyping by sequencing (GBS) approaches offer a highly cost effective alternative for simultaneous SNP discovery and genotyping. In the(More)
Parental care was analyzed separately with the PBI for both father and mother or their surrogate to assess its association with suicidal behavior (attempt or serious ideation). The study was conducted on two French-speaking samples from Montreal: the first included 2,327 high school students and the second 701 young adults (18 to 24) reached by phone.(More)
Next-generation sequencing (NGS) technologies have accelerated considerably the investigation into the composition of genomes and their functions. Genotyping-by-sequencing (GBS) is a genotyping approach that makes use of NGS to rapidly and economically scan a genome. It has been shown to allow the simultaneous discovery and genotyping of thousands to(More)
This research analyzes school integration of a sample of 150 adolescents lacking parental attention. A group of 78 suicidal students is compared to a group of 72 non-suicidals. Students are 14 to 17 years old and are recruited in six schools of the Montreal region. Suicidal adolescents do not experience more problems of discipline, absenteeism, academic(More)
A study made on a sample of 2,327 Montréal area students of third, fourth and fifth year of High School shows that suicidal behaviors ("les suicidaires") account for 13.2 % of youth interrogated, and that 6.7 % admit to having attempted suicide. The suicidal behavior rate is higher among girls than boys and it is lower in schools where the proportion of(More)
This article sums up the outcome of a research project conducted in Montreal schools in 1987 and 1988, and focusing on how family ecology and social networks relate to strong suicidal tendencies among teenagers. Two groups were involved in the study: one with 78 suicidal persons, the other with 72 non-suicidal persons. Teenagers in each group were(More)
