Stem Cells: Biology and Promise for Regenerative Medicine by Elaine Fuchs, Jan. 2007 - Part 1: Introduction to Stem Cells and Ethical Issues (35:11)

During embryogenesis, a single fertilized oocyte gives rise to a multicellular organism whose cells and tissues have adopted differentiated characteristics or fates to perform the specified functions of each organ of the body. As embryos develop, cells that have acquired their particular fate proliferate, enabling tissues and organs to grow. Even after an animal is fully grown, however, many tissues and organs maintain a process known as homeostasis, where as cells die, either by natural...

Genes and Cells that Determine the Lifespan of C. elegans - Part 1: An Evolutionarily-Conserved Regulatory System for Aging (42:46)

submitted by: video_collector
Once it was thought that aging was just a random and haphazard process. Instead, the rate of aging turns out to be subject to regulation by transcription factors that respond to hormones and other signals. In the nematode C. elegans, in which many key discoveries about aging were first made, the aging process is subject to regulation by food intake, sensory perception, and signals from the reproductive system. Changing genes and cells that affect aging can lengthen lifespan by six fold, and...

Part V - Business Approaches to Implement CSR

submitted by: asantos
6 CORPORATE STRATEGIES TO IMPLEMENT CSR 6.1 Context A number of variables affect the strategy that a given company chooses to implement its CSR, including its structure, size, culture and business strategy. CSR strategies might also be affected by how close they are to the core business or the proximity that it demands from the community that has been affected. Defining the appropriate strategy for CSR is one of the roles that can be played by the designer since he/she can have the...

Part III - Drivers for CSR

submitted by: asantos
4 DRIVERS/BARRIERS FOR CSR In order to allow a designer to understand his/her role within a CSR initiative it is important he/she understand the various motivations that could drive a business (and a businessman) to invest company assets into social responsibilities. It is important to call attention to the fact that these CSR drivers could also be understood as barriers for CSR on those situations when they are absent. Hence, the focus of the designer on his/her creative process would...
