Modern communication technology has allowed China to achieve a centralized bureaucracy that has a smaller chance of becoming overextended and too top heavy. This perspective on the media audience was the subject of substantial debate and discussion at the time (e.g., Livant, 1979; Murdock, 1978; Smythe, 1978). In the years since, however, this perspective has received relatively little attention in communications scholarship (Artz, 2008; for exceptions, see Andrejevic, 2002; Cohen, 2008; Shimpach, 2005). However, just as contemporary developments in the media environment have invited a reconsideration of the concept of mass communication, so too do they invite reconsideration of this corollary notion of the work of the mass audience. The 16th of February 2005 was the dawn of our struggle. On that day the Kennedy Road committee had a very successful meeting with the chair of the housing portfolio of the executive committee of the municipality, the director of housing and the ward councillor. They all promised us the vacant land on the Clare Estate for housing. The land on Elf Road was one of the identified areas. But then we were betrayed by the most trusted people in our city. Just one month later, without any warning or explanation, bulldozers began digging the land. People were excited. They went to see what was happening and were shocked to be told that a brick factory was being built there. More people went down to see. There were so many of us that we were blocking the road. The man building the factory called the police and our local councillor, a man put into power by our votes and holding our trust and hopes. The councillor told the police Arrest these people they are criminals.â€ The police beat us, their dogs bit us and they arrested 14 of us. We asked what happened to the promised land. We were told Who the hell are you people to demand this land?â€ This betrayal mobilised the people. The people who betrayed us are responsible for this movement. Those people are the second force. Introduction to noise and linearity concepts. System budgeting for optimum dynamic range. Frequency plan tradeoffs. Linearity analysis techniques. Down-conversion and up-conversion techniques. Modulation and demodulation. Microwave and RF system design communications. Current research topics in the field. Prerequisites: ECE 166 or consent of instructor; graduate standing. Additionally, take note of the difference between each device’s sensitivity to minor motion (working at a desk) vs. major motion (walking or half-step activity). The sensor manufacturer should provide coverage diagrams for both levels of activity. HID lamps do not work well with occupancy sensors because most HID lamps take a long time to start each time they are switched off.
