in this research by applying the theoretical framework of socio-technical systems and literature review using the form of e-government has been identified as a core component. to realize the model results and the results indicated that each of the six components of e-government in 1404 particularly in the areas of communication and access to digital content. based on the results of the highest ...
Cooling flow models for the hot gas in elliptical galaxies predict that gas is cooling at a rate of ∼ 1 M⊙ yr , yet there is little evidence for this phenomenon beyond the X-ray waveband. If hot gas is cooling, it will pass through the 3× 10 K regime and radiate in the O VI λλ1032,1038 ultraviolet lines, which can be detected with the Far Ultraviolet Spectroscopic Explorer (FUSE ) and here we r...
We have identified a new intermediate polar, HS 0943+1404, as part of our ongoing search for cataclysmic variables in the Hamburg Quasar Survey. The orbital and white dwarf spin periods determined from time-resolved photometry and spectroscopy are P orb ≃ 250 min and Pspin = 69.171 ± 0.001 min, respectively. The combination of a large ratio Pspin/P orb ≃ 0.3 and a long orbital period is very un...
Inspired by Adam Smith and Friedrich Hayek, many economists have postulated the existence of invisible forces that drive economic markets. These market forces interact in complex ways making it difficult to visualize or understand the interactions in every detail. Here I show how these forces can transcend a zero-sum game and become a win-win business interaction, thanks to emergent social syne...
The emergence of profit-based online platforms for the peer-to-peer sharing of consumer goods provides new means for the end users to derive profit from their possessions. The success of these platforms relies heavily on the behavior of their participants. Using an agent-based model simulating these behaviors via different scenarios, we show how these mechanisms are efficient to improve the inf...
The analysis of Iran's knowledge economy suggests that the main weakness of the Iranian economy is the lack of processes of innovation and innovative entrepreneurship for the exploitation of new knowledge and technology. These processes fundamentally formed in the knowledge-based entrepreneurship ecosystems that did not developed in Iran economy and has not even known. Therefore, the purpose of...
Resistance economy is a term come across in literature of Iran economy that include lots of paper in this topic. Cities in national economy are a basis of production. Primer cities and metropolises are economy engines that cover major of goods and services production, and they are most important market for the goods and services produced in these cities, so that if these regions were not existe...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...
the present study aimed at investigating how different news agencies using the concept of legitimation/delegitimation represent the same event differently. to this end, van leeuwens (2008) legitimatory/delegitimatory framework was applied to the data gleaned from the iranian state-run news agency fars news, british state-run news agency bbc, and also american state-run news agency voa. the resu...
