Gender Specific Language: A Myth or a Reality in Evolution?
Hajar Ghafarpour and Shakiba Rostami
Language has been deemed to differ in use by each gender. Most of the research in this area focuses on the spoken language. The purpose of the present study is to probe the notion of genderlect in short stories by British or American male and female authors of 20 and 21 centuries. Hence a sample of 32 English short stories is selected 16 of which have female authors and 16 male authors, making four major categories of 19 century male and female and 20 century male and female. The investigated features include empty adjectives, boosters and intensifiers that were probed using the Word Smith Tools. To find out whether the difference is significant MANOVA is applied. The result shows no significant differences between male and female language in each century and a significant decrease in intensifier application in by the female group. Some probable reasons are discussed in the article.
Keywords: Genderlect, booster, intensifier, empty adjective

Urban Seismic Vulnerability Assessment using Fuzzy
Multi-Criteria Decision-Mak¬ing and Geographic Informa¬tion Systems: A Case Study Tehran Center Core Region 12
Mohsen Soltanabadi and Amir Razmi
Cities as human gathering places are subjected to natural disasters and in order to diminish the effects of these catastrophes should be made a decision. Urbanity accelerated growth along with vulnerability ecological region structure provokes environmental crisis and insecurity of sensitive and main areas in the city. The most manifest sample for this sort of urbanity is Tehran. This city due to its geographical location, surrounded by Alborz hillsides and river and flood basins, from one hand, and located on the abundant fault from other hand, is susceptible to vulnerability in front of natural disasters like earthquake. Vulnerability is being intensified by another factor; old urban texture that 12th region of Tehran is a manifest example here. In this study, we practice investigation and seismic vulnerability of 12 region of Tehran as the city core. The utilized method is a combination of new Delphi technique to characterize criteria and indices of vulnerability, multi-criterion decision-making regime including Fuzzy-AHP within GIS area to rank blocks subjected to danger. All blocks on 12th region are our items. In fact, in order to assess vulnerability, mere application of structural indices isn't enough and to obtain an accurate analysis utilizing demographic indices, spatial- skeletal structure and functional, environment and communication network is required. Results obtained from vulnerability plots by the means of abovementioned techniques allow managers and city planners to have realistic plan of the city. It also helps them to distinguish which field is much more important, how to perform different steps of earthquake risk management and prioritize facilities and resources allocation.

Optimization of using Wire Antenna in Mobile Communication Systems in Fourth Generation
Mehdi Khoshabi, Hossein Emami, Mahmoud Pirhadi and Mehdi Hosseinpour
Development of technology using software and hardware techniques, has designed some antennas with better performance than before. Today, cell phone is an unavoidable issue for developed or developing societies. Mobile systems have developed so much and many people would not be able to do their daily activities without them. This issue was a pertinent reason for optimizing these antennas in 4th generation communication systems. This study, considers increase in capacity through reuse of frequency. The aim of this study is to combine several antennas, so that they can optimize desirable power for desirable surface. Finally, regarding simulated results by software, it would be suggested that new construction improves width of impedance band and decreases back lobe of micro-strip antenna. Antenna has been always an important component of wireless communication system. In fact, antenna is a hatch, which sends electromagnetic energy to channel and then to receiver through radio waves. During this process electromagnetic energy would be distributed to the surrounding area and would be received again. During the process there are also some effective factors, which would affect frequency, new networks and service quality significantly. There are antennas with different features and kinds, which would be classified considering their design and radiation pattern. These features would optimize antenna for a certain application. Therefore, antennas would be dividend into two groups generally including multi-dimensional and limited-angle radiation antennas.

Musa Khan and Musab Yousufi
Radio is an effective tool of Media that has a strong effect on the behavior of people and plays an important role in the process of setting minds of people towards an issue in positive or in negative way. Through this research it has been investigated that, In Malakand division, area of Pakistan where the literacy is low, areas are vast and means of communication insufficient, FM broadcasting is very effective, advance and important instrument because of its locality, closeness, quickness, easy access, easy operating, cheap, and infinite reach, which has many effects on the behavior of people of this area. It has been also investigated and discussed through quantitative research that since last two years during militancy FM radio played a negative role and misguided the innocent people of the area towards extremism with the misinterpretation of religion. The FM broadcasting used to change the mind and attitude of people towards social instability, extremism and against state. In this paper the researcher tried to find two important things that, what were the content of these FM stations and what are the impacts on audience of these radios in the area. Purposive sampling technique was used for data collection and survey conducted from two hundred sample of the total population. And it is examined that the content of these radios were totally biased and Taliban (militants) used the Fm radios as a war tool and strongly affected the mind of innocent people of the area.
