The size of DNA replication intermediates from Drosophila cells pulse-labeled with 3H-thymidine for 30-120 sec was determined by electrophoresis in formamide-polyacrylamide gels. Replication intermediates were formed in three discrete size classes, with median lengths of 61, 125 and 240 nucleotides. Replication intermediates in the 125 nucleotide size class(More)
There has been considerable recent interest in understanding the role of positive inter-specific interactions within ecology, and significant progress has been made both empirically and theoretically. Similarly, considerable progress has been made in improving our understanding of the mechanisms that limit species' ranges. In this contribution, we seek to(More)

Measurements of the age difference between coexisting benthic and planktic foraminifera from western equatorial Pacific deep-sea cores suggest that during peak glacial time the radiocarbon age of water at 2-kilometers depth was no greater than that of today. These results make unlikely suggestions that a slowdown in deep-ocean ventilation was responsible(More)
Introduction Current and emerging advances in the science of genetics provide significant promise for enhanced health and well-being and an opportunity for social workers to make a major contribution. As rapid discoveries in genetics (the study of single genes and their effects) and genomics (the study of the functions and interaction of all the genes in(More)
The Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3) and its earlier versions are measures designed to assess societal and interpersonal aspects of appearance ideals. Correlational, structural equation modeling, and prospective studies of the SATAQ-3 have shown consistent and significant associations with measures of body image(More)
" The major challenge of social work is that social workers have too many things on their plates. They cannot possibly do everything they need to do and do it well. Burnout is a main reason people are leaving the profession. We are short-handed as it is… " —Survey Participant The 2004 benchmark national study of licensed social workers provided a wealth of(More)
