Ethics of Population-Based Research
Journal of Law, Medicine & Ethics, 2007Multiple scholars and institutions have asked what distinguishes public health research from public health practice. Most often, they ask in order to have a clear definition of what one does in various public health settings to assess oversight and/or regulation of human subjects research.

A population-based study of craniosynostosis
Journal of Clinical Epidemiology, 1990A population-based study of the incidence of craniosynostosis was conducted among residents of Olmsted County, Minnesota, born between 1 January 1976 and 31 December 1985. This study included only those with primary craniosynostosis who were less than 5 years of age at the time of diagnosis.

Most of the studies this monograph is concerned with—hospital-based studies of pregnant diabetic women—were conducted in special medical facilities, including diabetes clinics, i.e. facilities whose patients may have needed special care, and who therefore may not have been a true cross-section of all pregnant diabetic women in that time and place.

Population-based genetic screening
Current Opinion in Genetics & Development, 1991A preventive genetic programme aimed to control beta-thalassemia in the Sardinian population is based on a combination of increased awareness of the population, carrier screening, genetic counselling and prenatal diagnosis. As a result, the registry of thalassemia major demonstrated a profound decline in the incidence of this disease from 1 per 250 to ...

A Population Based Approach for ACO
2002A population based ACO (Ant Colony Optimization) algorithm is proposed where (nearly) all pheromone information corresponds to solutions that are members of the actual population. Advantages of the population based approach are that it seems promising for solving dynamic optimization problems, its finite state space and the chances it offers for ...

Ensemble strategies for population-based optimization algorithms - A survey
Swarm and Evolutionary Computation, 2019In population-based optimization algorithms (POAs), given an optimization problem, the quality of the solutions depends heavily on the selection of algorithms, strategies and associated parameter combinations, constraint handling method, local search ...

Implementing Population-Based ACO
2014Population-based ant colony optimization (PACO) is one of the most efficient ant colony optimization (ACO) algorithms. Its strength results from a pheromone memory model in which pheromone values are calculated based on a population of solutions. In each iteration an iteration-best solution may enter the population depending on an update strategy ...

Population based cohort study of injuries
Journal of Clinical Epidemiology, 1996A population-based cohort study was done to estimate the incidence of different types of injuries and to evaluate certain risk factors in an urban slum; 4333 slum dwellers in Madras city in India were randomly selected by cluster sampling, of whom 1.7 per cent were lost during the 12 months of follow up.
