It is possible that what appear to be references to one ship are in fact coincidental descriptions of different destroyers sharing a single name. For instance, several ships of different classes have used the name Vengeance, and not all of them were Imperator-class destroyers. There has also been more than one Iron Fist. In these cases, successive commanders have kept the name when they moved to newer vessels upon promotion.
Why Twin Studies? Twins provide a valuable source of information for health and psychological research, as their unique relationship allows researchers to pull apart and examine genetic and environmental influences. Twin study findings have been influential in detecting and treating various diseases and psychological disorders. How are they able to do this? Twin studies allow researchers to examine the overall role of genes in the development of a trait or disorder.
Your journey into psychology. Clinical psychologists work largely in health and social care settings including hospitals, health centres, community mental health teams, Child and Adolescent Mental Health Services (CAMHS) and social services. They often work as part of a team with other health professionals and practitioners. Most clinical psychologists are employed by the National Health Service (NHS), but some work in private practice.
