background: the species of ectoparasites that live on a specific host in a geographical region form an ectoparasite community. species abundance distributions describe the number of individuals observed for each different species that is encountered within a community. based on properties of the species abundance distribution, the expected total number of species present in the community can be...

The present note shows that the concept of a distribution economy (Hildenbrand (1974)) is closely related to a framework of an exchange economy in which the agents’ individual characteristics (i.e. preferences and endowments) are random (Hildenbrand (1971), Bhattacharya and Majumdar (1973), Föllmer (1974)). A random exchange economy is fully specified by the distribution of the family of random...

fuzzy set based methods have been proved to be effective in handling many types of uncertainties in different fields, including reliability engineering. this paper presents a new approach on fuzzy reliability, based on the use of beta type distribution as membership function. considering experts' ideas and by asking operators linguistic variables, a rule base is designed to determine the level ...

introduction: family planning is the most effective strategy in reducing the world population. family planning was replaced by reproductive health since 1994 and the role of men is one of the most important aspects of this program. therefore, determination of men's knowledge in family planning and the role of education in enhancing the awareness are important. this study has been performed...

Introduction: Hospitalization of patients in the critical care units greatly affects their families and their balance. Attention to family needs can affect the treatment process. Identifying the needs of patients’ families and the extent to which they can be fulfilled can affect the treatment process. Objectives: The purpose of this study was to determine the importance of family needs o...

Given a family of null hypotheses $H_{1},\ldots,H_{s}$, we are interested in the hypothesis $H_{s}^{\gamma}$ that at most $\gamma-1$ these false. Assuming corresponding $p$-values independent, investigating combined valid for testing $H_{s}^{\gamma}$. In various settings which is false, determine $p$-value works well setting. Via simulations, find Stouffer method if uniformly distributed and si...
