We develop a parsimonious bivariate model of inflation and unemployment that allows for persistent variation in trend inflation and the NAIRU. The model, which consists of five unobserved components (including the trends) with stochastic volatility, implies a time-varying VAR for changes in the rates of inflation and unemployment. The implied backwards-looking Phillips curve has a time-varying ...

A perusal of literature of some of the plants used for Jaundice (Nadkarni 1908, & 1976, Anonymous 1918, Chopra et al 1956 Kirtikar & Basu 1935; Anonymous 1956; Nadkarni and Nadkarni 1976, Moideen Sheriff 1978, Mathew 1983, Abstr, from Jour. Medicinal & Aromatic plants 1982 – 84) have revealed surprisingly that no – where in the literature references pertaining to the use of Flaveria trinervia (...

This ancient institution (one of the first, if not the oldest, asylums for lunatics in Europe) was founded in 1247, during the reign of Henry III., by Simon Fitzmary, a sheriff of London, at Bishopsgate, when it was designated the Priory of Bethlehem, At the dissolution of the religious houses, the property was seized by Henry VIII., who in 1547 granted the Priory, with all its revenues, to the...

In 1958, A.W. Phillips discovered a strong negative correlation between inflation and unemployment in United Kingdom data. Continuing controversy surrounds the long-run trade-off suggested by a curve he drew through these observations. We conduct a wide-ranging investigation of the post-war U.S. Phillips correlations and Phillips curve. Many economists view the Phillips correlations as chimeric...

In this paper we propose a multi-objective mathematical model to aid the marketing team of a company in customer service marketing. Customer reflects to the services provided by a company, and the reflections affect the profit of the company. Thus, the services can be evaluated by the customers to imply the company's performances. First, the services are purified based on the opinions of th...

in a supply chain, cross-docking is one of the most innovative systems for ameliorating the operational performance at distribution centers. cross-docking is a logistics strategy in which freight is unloaded from inbound trucks and (almost) directly loaded into outbound trucks, with little or no storage in between, thus no inventory remains at the distribution center. in this paper, we consider...

consideration of the current-voltage (i-v) characteristics variations of solar modules with temperature and irradiations variations is basic for maximum power point tracking (mppt). having a simple and accurate mathematical model for the optimize utilization of the solar modules is essential. in this paper, a novel modeling of photovoltaic systems with novel coefficients is proposed for mathema...

conclusions we found a large impact due to nsps for reducing the occurance of hiv among active drug injectors who have been provided sufficient needles and syringes. the coverage of nsps needs to be increased to observe such significant impact. results given the output of the model, we found that among the pwid with sufficient coverage of nsps the hiv rate is 1.02%, while those with insufficien...
