Youth mentoring programs must change in order to become truly effective. The world’s leading expert shows how. Youth mentoring is among the most popular forms of volunteering in the world. But does it work? Does mentoring actually help young people succeed? In Older and Wiser, mentoring expert Jean Rhodes draws on more than thirty years of empirical research to survey the state of the field. Her conclusion is sobering: there is little evidence that most programs—even renowned, trusted, and long-established ones—are effective. But there is also much reason for hope. Mentoring programs, Rhodes writes, do not focus on what young people need. Organizations typically prioritize building emo...

Nonviral Vectors for Gene Therapy
Gene transfer within humans has been an obstacle until about 10 years ago. At that time, it was found that viral vectors were effective carriers of "healthy genes" into patients' cells. The problem, however, was that viral vectors proved unnecessarily harmful to humans: subjects experienced inflamatory activity and negative immunological responses to the genes. Viral vectors were also unable to meet the needs of the pharmaceutical community: they were not reproducible in large-scale proportions in cost-effective ways.Thus, research was undertaken to find a safer way to transfer genes to patients without jeopardizing the safety of the patient. And so non-viral vectors were discovered. This vo...
Differentially Expressed Genes In Plants
The analysis of changes in gene activity in tissues and cells of plants is a way of measuring developmental and environmental responses. This volume provides detailed accounts of new and established techniques used to carry out such analyses.
