We study a growth model for a single resource-based economy, as an infinite-horizon optimal control problem. The resource is assumed to be governed by the standard model of logistic growth, and is related to the output of the economy through a Cobb-Douglass type production function with an exogenously driven knowledge stock. The problem involves unbounded controls and the non-concave Hamiltonia...

â â â  â â  abstract â  the importance of community's health followed by the consideration of endogenous growth models has led to an increase in health expenditure of countries to speed up economic growth and development. this has made the efficiency of health production function to an essential issue especially in developing countries. based upon this, the present study with employing the...

Exchange of resources among individual components a system is fundamental to systems like social network humans and cities villages. For various reasons, the human society has come up with notion money as proxy for resources. Here we extend model resource dependencies in networks that was recently proposed by one us, incorporating concept so vertices can sell buy required themselves. We simulat...

Ambidexterity has been linked to firm structures that are typical of organizations with a larger size. However, further research is needed analyze whether the effect size on ambidexterity contingent other aspects. We argue micro and small firms have developed some competitive intelligence routines (CIRs) may foster ambidextrous behavior compensate for limitations arising from smaller lack resou...

In this paper we present our contribution to SemEval-2014 Task 4: Aspect Based Sentiment Analysis (Pontiki et al., 2014), Subtask 2: Aspect Term Polarity for Laptop domain. The most outstanding feature in this contribution is the automatic building of a domain-depended sentiment resource using Latent Semantic Analysis. We induce, for each term, two real scores that indicate its use in positive ...

Context. Among optical stellar interferometers, the CHARA Array located at Mt Wilson in California offers the potential of very long baselines (up to 330 m) and the prospect of coupling multiple beam combiners. This paper presents the principle and the measured performance of VEGA, Visible spEctroGraph and polArimeter installed in September 2007 at the coherent focus of the array. Aims. With 0....
