Complexity science suggests that our current health care delivery system acts as a complex adaptive system (CAS). Such systems represent a dynamic and flexible network of individuals who can coevolve with their ever changing environment. The CAS performance fluctuates and its members' interactions continuously change over time in response to the stress generated by its surrounding environment. ...

Asian American (ASA) children experience high rates of mental health problems. Although there is a pressing need to utilize population approaches, emerging frameworks from the fields of public and population health have not been applied to ASA children. This paper addresses this gap by first discussing applications of the National Prevention Strategy (NPS), a population strategy developed from ...

the implementation of different silvicultural systems can be effective on different characteristics of forest stands, such as stand structure and diameter distribution of trees. this study was carried out in shafaroud forests of gilan province of northern iran. the objectives of this research were 1) to evaluate the suitability of different probability distribution functions, including weibull,...

This paper presents a multi objective geometric programming model which determines the product`s selling price in two markets. We assume demand is a function of price and marketing expenditure in two markets. The cost of production is also assumed to be a function of demands in both markets. Our model is a posynomial function which is solved using Geometric Programming (GP). In our GP implement...

in present pet/ct scanners, pet attenuation correction is performed by relying on the information given by ct scan. in the ct-based attenuation correction methods, dual-energy technique (dect) is the most accurate approach, which has been limited due to the increasing patient dose. in this feasibility study, we have introduced a new method that can implement dual-energy technique with only a si...

the current challenge in health services research is disability to present comprehensive and effective intervention plans for community health promotion. there are numerous reasons in this regard, some of which can be overcome through performance-based participatory research methods. the population research center (prc) in tehran university of medical sciences (tums) provides the necessary grou...
