Personnel Selection: The process of choosing employees for specific types of employment. The concept includes recruitment.Selection, Genetic: Differential and non-random reproduction of different genotypes, operating to alter the gene frequencies within a population.Military Personnel: Persons including soldiers involved with the armed forces.Personnel, Hospital: The individuals employed by the hospital.Health Personnel: Men and women working in the provision of health services, whether as individual practitioners or employees of health institutions and programs, whether or not professionally trained, and whether or not subject to public regulation. (From A Discursive Dictionary of Health Care, 1976)Allied Health Personnel: Health care workers specially trained and licensed to assist and support the work of health professionals. Often used synonymously with paramedical personnel, the term generally refers to all health care workers who perform tasks which must otherwise be performed by a physician or other health professional.Personnel Management: Planning, organizing, and administering all activities related to personnel.Military Medicine: The practice of medicine as applied to special circumstances associated with military operations.Medical Laboratory Personnel: Health care professionals, technicians, and assistants staffing LABORATORIES in research or health care facilities.Models, Genetic: Theoretical representations that simulate the behavior or activity of genetic processes or phenomena. They include the use of mathematical equations, computers, and other electronic equipment.Emergency Medical Technicians: Paramedical personnel trained to provide basic emergency care and life support under the supervision of physicians and/or nurses. These services may be carried out at the site of the emergency, in the ambulance, or in a health care institution.Evolution, Molecular: The process of cumulative change at the level of DNA; RNA; and PROTEINS, over successive generations.Personnel Staffing and Scheduling: The selection, appointing, and scheduling of personnel.Biological Evolution: The process of cumulative change over successive generations through which organisms acquire their distinguishing morphological and physiological characteristics.Genetic Variation: Genotypic differences observed among individuals in a population.Patient Selection: Criteria and standards used for the determination of the appropriateness of the inclusion of patients with specific conditions in proposed treatment plans and the criteria used for the inclusion of subjects in various clinical trials and other research protocols.Selection Bias: The introduction of error due to systematic differences in the characteristics between those selected and those not selected for a given study. In sampling bias, error is the result of failure to ensure that all members of the reference population have a known chance of selection in the sample.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.War: Hostile conflict between organized groups of people.Naval Medicine: The practice of medicine concerned with conditions affecting the health of individuals associated with the marine environment.Personnel Staffing and Scheduling Information Systems: Computer-based systems for use in personnel management in a facility, e.g., distribution of caregivers with relation to patient needs.Iraq War, 2003-2011: An armed intervention involving multi-national forces in the country of IRAQ.Laboratory Personnel: Professionals, technicians, and assistants staffing LABORATORIES.Phylogeny: The relationships of groups of organisms as reflected by their genetic makeup.Genetics, Population: The discipline studying genetic composition of populations and effects of factors such as GENETIC SELECTION, population size, MUTATION, migration, and GENETIC DRIFT on the frequencies of various GENOTYPES and PHENOTYPES using a variety of GENETIC TECHNIQUES.Afghan Campaign 2001-: Multinational coalition military operation initiated in October 2001 to counter terrorism and bring security to AFGHANISTAN in collaboration with Afghan forces.Mutation: Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.United StatesPersonnel Delegation: To entrust to the care or management of another, to transfer or to assign tasks within an organizational or administrative unit or structureIraqAttitude of Health Personnel: Attitudes of personnel toward their patients, other professionals, toward the medical care system, etc.Base Sequence: The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.AfghanistanAmbulances: A vehicle equipped for transporting patients in need of emergency care.Operating Rooms: Facilities equipped for performing surgery.Phenotype: The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.
