In this study the authors evaluated the prevalence of Gestational Diabetes Mellitus (GDM) and the incidence in determining the occurrence thereof, given by the following risk factors: age, family history for Diabetes Mellitus (DM), Body Mass Index (BMI), smoking, diet, macrosomia in previous pregnancies and physical activity. To this end, they investigated a cohort of 61 pregnant women, who had...

Let Mn,m be the set of all n × m matrices with entries in F, where F is the field of real or complex numbers. A matrix R ∈ Mn with the property Re=e, is said to be a g-row stochastic (generalized row stochastic) matrix. Let A,B∈ Mn,m, so B is said to be gw-majorized by A if there exists an n×n g-row stochastic matrix R such that B=RA. In this paper we characterize all linear operators that stro...

We investigate the credit risk model defined in Hatchett and Kühn [18] under more general assumptions, in particular using a general degree distribution for sparse graphs. Expanding upon earlier results, we show that the model is exactly solvable in the N →∞ limit and demonstrate that the exact solution is described by the message-passing approach outlined in Karrer and Newman [21], generalized...

Since the papers of Basu et. al. (1985) and Lal and Srinivasan (1993), marketing academics have been interested in the design and implementation of optimal compensation plans. The literature has focused on agency theory as a foundation to help describe and understand this process. Although there has been much theoretical work on this topic, empirical evidence to support this theory remains spar...

This paper studies an inverse problem of determining the implied volatility in the financial products linked with gold price, which has important application in financial derivatives pricing. Based on the total variation regularization strategy, the existence and necessary condition of the minimum for the control function are addressed, and the local uniqueness of the solution is also given by ...

Current poverty measurement methodology does not allow a definitive analysis of changes in distribution, through time or between countries, which involve changes in the number or proportion of poor people. By reopening some of the discussion which has taken place around the incidence, intensity and inequality aspects of poverty, and by revisiting the continuity and transfer axioms, we show that...
