The export sector is the main driver of the development process of any country and one of the main pillars of its economy, the importance of exports lies in their ability to create new jobs, reform the deficit in the balance of payments, and attract
private investment, both domestic and foreign then they help achieve sustained growth rates. They are also the most important sources of foreign exchange, and without export the economy fails to develop and unemployment increases.
This research studies the evolution of Syrian trade balance during the period 2000 – 2010. Results show that the balance of trade suffered a deficit between (2004-2010). exports were much lower than imports. Oil exports and their impact on total exports and on the Syrian economy in general as well as agricultural exports and their share in total exports were also analyzed using Hirschman Index.
This research aims to shed a light on the distinctive economic characteristics of water
resources and to identify the reasons that led to increasing interest in studying these
resources and their economics.
depending on descriptive analytical meth
od through characterization of what is and
analyze it, The researcher is addressing the policies necessary to be followed for a
successful allocation of water balances within the time periods, and define whether the
water resources are to be considered as an economical good and whether they are subjected
to market mechanisms, i.e. demand and supply.
the research results pointed out to the fact that the water resource is a strategic vital
resource and an economic good has a special nature which make it not subject to market
mechanisms.
this study is providing a number of proposals that emphasize the need to focus on the
economics of water resources to attain the efficiency of resource exploitation, which, on
the one hand, leads to achieving sustainability of this valuable resource, and on the other
hand fulfill maintain the economic development.

The purpose of this article is to examine the possibility of immediate against mediated or theoretical knowledge. However, in both types of knowledge, there is a face to face confrontation. I encounter something which I wish to apprehend. Therefore,
aspiration already assumes a duality, a gulf between me and that which faces me. The object is, as it were, already there, autonomous, present as a fact. This is, of course, a basic tenet of positivism and empiricism. The world as summation of all its possible contents is simply 'given'. This article also tries to enquire a little further into this perspective, questioning the nature of this objectivity exploring possible ambiguities. I shall be looking mostly at Kantian transcendentalism and Husserlian and Merleapontian phenomenology.
In this thesis an analytical study is done on existing cloud
resource allocation strategies and a comparative study summarize
them on the basis of technique used and objective as well as their
advantage and disadvantage.
