Scientific advances on Cloning - Research Paper Example Some have suggested that the â€Å"fear of the unknown† aspect of cloning mammals, though understandable, is largely unfounded. The potential benefits are numerous and outweigh the concerns brought forth by those who don’t fully understand the process or implications of cloning. Laws and regulations related to this new science will be implemented to address the ethical implications but it’s impossible to stop scientific exploration. The birth of Dolly the sheep represents the birth of a new, exciting scientific method that will change the course of medical history for the better. The Scottish scientist Ian Wilmut of the Roslin Institute, along with his colleagues, announced on February 23, 1996 they had cloned a sheep by using a ground-technique. The method involved transplanting genetic matter from an adult sheep into a hollowed-out egg, an egg that had its nucleus removed. â€Å"The researchers fused the adult udder cell with an (egg) that was ready to be fertilized, but taken from a different sheep. The scientists had previously removed the nucleus from the (egg) using an electrical current to fuse it with the udder cell.† (Barnes, 2012). This sequence instigated cell division. The resulting embryo was then implanted into another sheep who acted as the surrogate-mother. The secret to this method’s success was making the nucleus of the donor’s udder cell â€Å"silent† so it would quit performing as it was originally intended and then reprogrammed it to act as an embryonic cell. That embryo would become Dolly; a sheep with three â€Å"mothers† involved but only related biologically to the one that donated an udder cell. Dolly shared all of the udder donor’s chromosomes but none of the host egg cell’s chromosomes. Consequently, Dolly is an exact genetic reproduction of the donor-cell sheep.

What is Organizational Psychology Letter - Essay Example Organizational psychology has been in existence since the previous century - since factories began their operations. The owners of these factories aimed at gaining profits, and they did not consider the employees’ interest and well-being. Psychologists used their knowledge in testing employees in different occupations. Between 1924 and 1932, psychologist Harry Landsberger discovered that employees performed better when they felt that someone else was interested in their work, for instance, supervisors in white coats, who carried clipboards, were an inspiration to employees (Cogniphany, 2008). The study of the history of organizational psychology informs us on how far we have come, and the importance of the previous ideas, which can determine the future of organizational psychology. Organizational psychology brought about change in work, after the First World War, the then industrial psychologists were interested in fatigue and efficiency, and researched on how to design work that would yield maximum profits (Furnham, 2005, p.62). However, the present organizational psychologists are interested in the well-being of employees, and the effect they have on the organization. In 1960, McGregor differentiated between the assumptions that managers have on employees. Theory X stated that the supervision approach is determined by managers’ view on human nature. This theory insists that human beings hate working; therefore, they must be controlled or punished for organizational goals to be achieved. Therefore, high levels of control would be exercised by managers who support theory X. whilst theory Y insisted on the application of less control, this theory acknowledges that people view work as a natural activity, and therefore, they are committed to work if they are motivated with rewards (Furnham, 2005, p.67). The Hawthorne effect indicated that employees respond positively to change in the work
