Introduction:     women's  employment  is one of the fundamental problems in breastfeeding. Studies have shown that after delivery, amount of milk is  equal in the mothers working and non-working. But  after several   months will be reduced markedly. Methods: In this study, with different departments was done coordination , and interviewed with the 351 mothers that had children under two years...

This paper studies an overlapping generations model with multiple securities and heterogeneously informed agents. There are two types of multiplicity of equilibria, one due to noisy rational expectations and the other resulting from self-fulfilling prophecies. Under general conditions, there exists an equilibrium in which stock returns are highly volatile and strongly correlated, even if all un...

This paper incorporates excess volatility in stock prices into a standard general equilibrium model and finds large welfare gains from stabilizing policies. Stock prices in this model aggregate information about fundamentals which is dispersed in the economy but also reflect excess volatility stemming from correlated distortions in beliefs. To solve the model, this paper develops a novel soluti...

A water use simulation for citrus (Citrus sinensis) was used to estimate the effects of climate, soil-available water, rooting depth, allowable depletion of available water, and partial coverage irrigation on the annual irrigation requirements. The soil in the study was excessively drained Candler sand (hyperthermic, uncoated Typic Quartzipsamments) of the Central Florida Ridge. Variation of an...

We revisit classical sieves for computing primes and analyze their performance in the external-memory model. Most prior sieves are analyzed in the RAM model, where the focus is on minimizing both the total number of operations and the size of the working set. The hope is that if the working set fits in RAM, then the sieve will have good I/O performance, though such an outcome is by no means gua...

We present a 37-week female baby, known with intrauterine growth restriction since 25 weeks of pregnancy, born with a placenta with an excessive long umbilical cord (ELUC), without any other abnormalities. ELUC is mostly an incidental finding after delivery, but represents a potentially detectable intrauterine cause of growth restriction. A system that allows ultrasound measurement of the lengt...

Received June 28, 1988; accepted August 14, 1988. metal suspension device, can be lifted or lowered by means of a hand crank that controls the elevation of the frame. In the CT suite, the patient is placed supine on a plastic spinal buckboardl A single sling is positioned underneath the buckboard at the level of the patient's thighs. The sling is then connected to two Hoyer lifts, one on each s...

This research relies on complementary variable- and person-centred approaches to investigate the underlying dimensionality of workaholism construct. In three studies (Study 1: N = 343 workers; Study 2: 654 firefighters in Sample 1 247 administrative technical employees 2; 3: 153 nurses 359 educators 2), results showed that employees' ratings simultaneously reflected a global overarching constru...

This article reviews the mainstream leadership literature and its perennial debates and compares it to the public-sector (administrative) leadership literature. The mainstream leadership literature fully articulated the transformational models in the 1980s and began the serious work of integrating transactional and transformational types of leadership into comprehensive models in the 1990s. Man...
