rural economy has an important role in rural sustainable development in every region or country. however, the rural economy in iran is too much depending on agriculture and development of other rural economy in particular nonfarm activities, has been neglected by iranian rural communities. therefore, the aim of this study was to identify the role of non-farm business on rural sustainable develo...

In this work we study numbers and polynomials generated by two type of composition of generating functions and get their explicit formulae. Furthermore we state an improvementof the composita formulae's given in [6] and [3], using the new composita formula's we construct a variety of combinatorics identities. This study go alone to dene new family of generalized Bernoulli polynomials which incl...

Staged tree models are a discrete generalization of Bayesian networks. We show that these form curved exponential families and derive their natural parameters, sufficient statistic, cumulant-generating function as functions graphical representation. give necessary criteria for classifying regular subfamilies discuss implications model selection.

An algorithm due to Bengalloun that continuously enumerates the primes is adapted to give the rst prime number sieve that is simultaneously sublinear, additive, and smoothly incremental: { it employs only (n= log log n) additions of numbers of size O(n) to enumerate the primes up to n, equalling the performance of the fastest known algorithms for xed n; { the transition from n to n + 1 takes on...

Poor households worldwide rely on savings groups (SGs) to satisfy their financial needs, yet very little is known about these groups’ ability to meet them. In this paper we develop a theoretical model illustrating the basic trade-offs in the functioning of SGs, and present stylized facts derived from the financial accounts of a sample of Ugandan SGs. The main conclusion from the theoretical mod...

The Nemours ModelTalker supports voice banking for users diagnosed with ALS/MND and related neurodegenerative diseases. Users record up to 1600 sentences from which a synthetic voice is constructed. For the past two years we have focused on extending and refining a web-based recording tool to support this process. In this demonstration, we illustrate the features of the web-based pipeline that ...

Recent welfare reform legislation requires increased parental work effort and imposes time limits on the receipt of federal assistance. These changes were based in part on assumptions that parental welfare receipt may be negatively related to family processes and children's attitudes and behaviors. Currently, researchers know little about the effects of welfare by itself relative to the effects...
