Abstract

The purpose of the paper is investigating relations between human development and economic growth, with a view to identifying major policies and prioritizing of them across Iranian provinces. In order to, human development index (HDI) between Iranian provinces over 1996, 2006 and 2001 have been created, and then with using the Co-integration and Granger causality technique have been measured long term relationships between economic growth and HDI. The findings suggest that although still inequality remains but the quality of life also has risen and these improvements seems have significant impact on long term economic growth. Also we find that HDI is positively influenced by Per capita GDP and if we want high levels of quality of life, we must dedicate a special consideration to economic growth in regional Policies across provinces.

Abstract
The aim of this contribution is to apply methods from optimal control theory to the mathematical modeling of biological pest control. We formulate a pest control strategy for nonlinear Kolmogorov system of n interacting populations by introducing natural enemies as a control function. The sufficient conditions for existence of an optimal feedback control function are based on the fact, that the steady-state solution of the Hamilton-Jacobi-Bellman partial differential equation is a Lyapunov function guaranteeing stability and optimality. We apply those general results to the Lotka-Volterra system with a logistic rate of increase of the prey population and Holling’s second type functional response of the predator population, to illustrate biological control of pest mite in stored grain Acarus siro by predatory mite Cheyletus eruditus.

Abstract
The paper analyzes the experience of Portuguese and Spanish hotel networks in Brazil, specifically on the Northern Coast of Bahia. We look at this process over the period when Brazil was opening up to international tourism corporations through promotion of national and regional policies. The research included surveying hotel representatives from investing countries. Clearly, there is a mighty convergence of interests between hotel groups, civil construction firms, and financial institutions, which appeals strongly to the political powers, particularly at a regional level. We also conclude that countries launching their tourism industry may learn from the experience of first comers with this crisscrossing research approach proving beneficial from various perspectives.
